The present invention relates to a washing machine a drum type having a door unit, located on the front side of the housing so that it can be freely opened and closed.

In a standard washing machine a drum type washing dryer used for drying, placed horizontally or obliquely, and is rotationally driven. For inserting or removing linen from the chassis from the front side there is opening. The doorway closes the door block.

The opening of the aperture is using the operation button is pressed. During operation of the washing machine unit door is locked, so that it was impossible to open it, which prevents the user from getting his hands into the rotating drum and eliminates the appearance, suddenly, washing water and the Laundry.

Figure 5 shows the appearance of a traditional washing machine drum. The housing 2 has an upward inclined surface 2A in the upper part of which is the continuation of his front side, on which there is a door unit 8 round shape. The user can open the unit door by pressing the release button 56, located on the inclined surface 2A.

Figure 6 shows a washing machine, in which the door unit is opened by pressing the release button 56. Door unit 8 is equipped with a latch 90, done is authorized in the form of a protrusion on the inner side. There is a locking device 59, mounted in the rear of the inclined surface 2A of the housing 2. There is also a latch with safety lock 91, providing further opening of the housing 2, and the heck with the safety forms part of a locking device 59.

When the unit door is open, the user puts the Laundry in the washing machine drum 5, are also used for drying, closes the door unit and starts the operation. At this time, the latch 90 is latched in the latch with safety device 91, and a door unit 8 is held in closed position by a locking device 59.

The following is a detailed description of the structure of the locking device and its important components. Figure 7 presents a drawing of the washing machine with a part of the external device near the inclined surface 2A to show the experimental structure of the opening and closing of the door block. On Fig presents a view of a vertical cross section along the line a-7, and figure 9 shows a horizontal section along the line C-D of figure 7.

As shown in Fig and 9, the axial force of the spring 92, the opening/closing actuator 93 and creating pressure on the protrusion 94, there is the back button 56 of the door opening. Opening/closing the actuator 93 is connected with a spring 69, which creates a pressure spring, and thus, opening gravause actuator 93 and the locking device 59 connected with the spring 69, as shown in Fig.7. The locking device 59 is equipped formed here by a latch with a safety device 91, as stated earlier. The heck with the safety 91 and the button 56, opening the door, located on the inclined surface 2A. Button 56, opening the door, held the rotating shaft 56A within a limited area.

In the following description discusses the opening sequence, in which the door unit 8 is opened from the closed position, when the user clicks on the button the door opening 56. In normal condition the axial force of the spring 92 is limited to opening/closing actuator 93 and is held in the open state of the button 56 in the front position by applying forces, as shown in Fig.7 and Fig.9.

When the user clicks on the button 56 opening the door with a force P in the direction of the arrow pointer, shown in Fig and Fig.9, the spring 92 with the axial force is compressed and presses the protrusion 94, then transmitting the force of the spring 92 opening/closing actuator 93, which becomes the focus. This leads to the fact that the opening/closing actuator 93 is rotated around a rotary axis 93A, serving as the fulcrum, and this movement of the opening/closing actuator 93 causes the force on the Azania on the spring 69.

The spring 69 is installed between the opening/closing actuator 93 and the locking device 59 thus, in order to maintain the predetermined tension. The other end of the spring 69 located within the device lock 59 is connected with a tension rod 111.

Therefore, when the tensile force applied to the spring 69, it affects the tension rod 111. This causes the locking circuit Board 113, interconnected with the tensioning rod 111 so as to rotate around a supporting shaft 114 and the release of the latch 90, held in the latch with safety device 91.

Shut-off fee 113 under the action of a lateral force of a locking spring 112 moves into the locking device 59 in the direction of the capture latch 90 inside of the latch with safety device 91, as shown in Fig.

As mentioned above, the amount of force needed to press on start button 56, must be sufficient to overcome the reactive force of the axial load of the spring 92 to rotate the opening/closing actuator 93, and an axial supporting force of the locking spring 112 to rotate the shut-off cost 113 using the tension force of the spring 69.

When the compression force on the button 56 of the door opening shot, gate fee 113 rotates under the influence of axial force of a locking spring 11, and it returns the protruding part A in the inner position of the latch with safety device 91. Immediately after the movement of the stretch rod 111 down, at the same time opening/closing actuator 93, pushed by the spring 69, rotates and forces the rear part of the door open button 56, to occupy the original position by the influence of the axial force of the spring 92.

The user pushes the door unit 8 from the open position to the closed position of the door panel 8. When this occurs, the latch 90 of the door block 8 squeezes shut-cost 113 and turns it, in spite of the axial force of the locking spring 112. Such movement of the latch cooperates with a projecting part A and forces her to re-take the state in which it was being closed.

In recent years, the demand for the creation of more than a simple sequence of actions for this type of washing machines. For ease of operation it is desirable, in particular, to increase the size of the button 56 of the door opening, as when the washing machine is used, the operation of opening and closing of the door panel 8 is always necessary. To improve performance, it is also desirable to reduce the amount of required pressure efforts.

However, in the construction discussed above, the button 56 opening doors and opening/closing of the Executive, milling the m 93 were constructed in compact form and shape and installed in a limited space and location. Button 56, opening the door, specially demanded a big enough push efforts to overcome the reactive force to rotate the shut-off cost 113 held by the spring 112, in addition to the force required to rotate the opening/closing actuator 93. In the result, the force required to press the button 56, opening the door, substantially increases.

The force applied to the locking device 59 via the button 56 of the door opening can be set in the following way from the assumption that the Central push the point m, where the compression force applied to the button 56 of the door opening, is in the same position as the Central point of acting on the opening/closing actuator 93 in terms of geometry 7. Let us assume here that the distance from the Central pressure point M to the rotary shaft 56A and a different distance from the Central point of impact of opening/closing the actuator 93 to torque shaft 93A are denoted respectively by the symbols K and j In accordance with the principle of levers, the force applied at the point of impact is proportional to the distance of the point of impact from the center of rotation. However, the power of Q, which acts on the locking device 59 with a force P is applied to the button 56, opening the door, can be expressed by equation (1):

Q=P(K/J)(1)

In equation (1) the magnitude of the force Q required for device lock 59 to allow the door to block 8 to remain in a fixed position. From this it follows that to improve performance it is necessary to increase the value of K/J in order to reduce the force P, which is the work effort for the user to click on the button 56 of the door opening.

However, it is difficult to increase the value of K, which represents the distance from the Central pressure point M on the button 56 opening the door to the rotary shaft 56A. To increase the K-factor there is not enough space, because the housing 2 has a limited distance, because the distance N from the rotary shaft 56 to the side wall 70 is small, as shown in Fig.7. On the other hand, in order to decrease the value of J, it is necessary to make the opening/closing actuator 93 is extremely small in size. In this case, changes in the value of J would significantly affect the force Q acting on the locking device 59, and therefore this case is not practiced.

In addition, the button 56 opening the door rotates horizontally, while the opening/closing actuator 93 is rotated VERTIC is correctly. After they are rotated along their respective axes, about the value of 90 degrees, there are also big loss efforts in a pressure point.

The present invention relates to a washing machine drum type, with high controllability by performing button door opening is large in size with a reduced force required for operation. Washing machine drum in accordance with the invention has a housing, a washing drum, the employee and for drying hopper, door block, button, opening doors, opening/closing actuator and the locking device. The housing has an aperture located on its front side. The washing drum is located inside the housing and is rotationally driven. Door unit round shape closes the opening of the housing. The button opening the door and managed by applying pressure effort, has a first rotary shaft. Opening/closing the actuator has a second rotary shaft, and he turns upon application of the pressure force to the button opening the door. The locking device of the door Assembly in the closed position operates in an interconnected movement together with the opening/closing actuator, and it releases the door unit to translate it from C the indoor location in the open by the push operation of the button opening the door. Button door opener is in such orientation that the normal of the first rotary shaft is inclined with respect to the second rotary shaft and directed toward the center of the door block. In this design it is possible to provide the desired tension on the locking device with an opening/closing the actuator, even when the control force from the button opening the door a little. The control buttons of the door opening can be improved.

Hereinafter the invention will be explained in more detail with reference to the accompanying drawings, which depict the following :

The following description refers to the example implementation of the present invention with reference to the accompanying drawings. An instance of an implementation, described below, is illustrative and does not imply that it may limit the scope of the present invention.

Figure 1 shows the external appearance of the washing machine drum in accordance with an example implementation of the present invention. Washing machine drum has a body 202, a washing drum 205, which serves to drain the tank, door block 208, the button 256 opening doors, opening/closing actuator 293 and the device 259 lock.

The housing 202 is in the upper part on the front side inclined surface indicated A. On the inclined side there is opening. In other words, the housing 202 has an aperture formed on the front side. Door unit 208 round shape is made so that it could be placed on the inclined surface A and close the opening of the housing 202. The washing drum 205 R is spoelgen inside the housing 202 and is rotationally driven. Thus, the washing drum 205, located inside the housing 202 rotates.

Button 256 door opening is controlled by application of the pressure forces and is located near the door block 208 on the front side of the housing 202. Thus, the button 256 door opener installed on the inclined surface A. The device 259 lock is mounted on the rear side of the inclined surface A. The device 259 lock keeps the door unit 208 in the closed position of the opening of the housing 202.

When the user clicks on the button 256 open the door, the device 259 lock releases the latch and opens the door unit 208. In other words, the push operation of the door opener button 256 sets the device 259 lock from the closed position in the state of opening of the door block 208. This allows the user to place and remove the Laundry from the washing drum 205. With reference to figure 2 and 3 below describes the structures associated with the operation of opening and closing of the door block 208. Figure 2 shows a detailed drawing of a portion of the structure near the button 256 opening doors and devices 259 lock. Figure 3 presents the drawing view showing the device structure 259 lock.

Opening/closing actuator 293 is located on the back side of the button 256 open the door the inside of the housing 202. Opening/closing actuator 293 under the action of the pressure force applied to the button 256 open the door, turns. In the normal position of the axial load of the spring, although it is not represented in the drawings, rests on the opening/closing actuator 293 and hold the button opening the door to its original position through its axial force. The device 259 lock, which operates in an interconnected movement of the opening/closing actuator 293, placed under the opening/closing actuator 293 inside the housing 202. Door unit is equipped with a latch (not shown) in the form of a protrusion from its inner side. There is also a latch with a safety device 291 is located next to open the housing 202, while it forms part of the device 259 lock.

The device 259 lock has a tension rod 311 and the locking plate 313, as shown in figure 3. Spring 269 connects the opening/closing actuator 293 and the tension rod 311. The device 259 lock has a construction similar to the device 59 lock presented on Fig.7.

When the user clicks on the button 256 opening the door, he thereby turns the shaft I called the first rotary shaft. This causes rotation otkryvayuschih the closing of the actuator relative to the shaft 293 A, called the second rotary shaft, in an interconnected movement with the turning movement of the key 256 open the door. At the same time opening/closing actuator 293 affects the device 259 lock through connected with him the spring 269. Thus, when the tensile force acts on the spring 269, spring 269 pushes up the tension rod 311. This movement acts on the locking plate 313 associated with the tensioning rod 311, which rotates relative to the shaft 314, which serves as a fulcrum. In the latch, closed the latch with safety device 291 is freed.

Locking plate 313 is pushed in the direction of fixing latch into the latch with safety lock 291 by means of the stop spring (not shown)located inside the unit 259 lock. However, when removed compression force on the button 256 door opener, locking plate 313 is rotated due to the axial force that the locking spring, and the protruding portion I moved back inside of the latch with safety device 291. Further, the tension rod 311 is also moved downward, opening/closing actuator 293, pushed by a spring 269, rotated, and thus the button 256 open the door returns to its original position.

For closing the door block 208, which is in the open state, the user will ehotelier. This leads to the fact that the latch of the door block 208 pushes and rotates the locking plate 313. In this sequence, the latch starts to interact with the protruding part A, and it is closed again.

Here the distance from the Central pressure point G button 256 open the door to the shaft A is denoted by the symbol E. the Central push the point G represents the point of impact on button 256 open the door. Button 256 door opener is located and designed in such a way that the normal to the axis of the shaft A and continuing from point G, that is, the normal N of the shaft A, directed toward the center of the door block 208.

The following is a description of the angular dependence between the button 256 opening doors and opening/closing actuator 293 with reference to figure 4. Figure 4 is a detailed perspective view button 256 door open.

Button 256 door opening is cut out part A annular frame 209 pivoting doors. Opening/closing actuator 293 is placed on the rear side of the button 256 open the door, and he turns into a coherent movement with the axis of movement of the button 256 door open.

The normal N of the shaft A button 256 door opening angle R, which is different from 90 degrees relative to the shaft A opening akrivega actuator 293, have usually horizontally. Thus, it can reduce the loss of influencing efforts. At this point the figure, it is preferable to have the angle R is not less than 20 degrees and not more than 45 degrees.

In the following description discusses the effort required in this structure for the lock device 259 lock. In figure 2 the distance from the point G, the Central point of impact of opening/closing the actuator on the shaft 293 A serving as a fulcrum opening/closing actuator 293, denoted by L. In accordance with the principle of interaction of the levers, the force acting at the point of actuation, is proportional to the distance from the point of impact to the center of rotation. Therefore, force T, which acts on the top of the device 259 locking force S applied to the button 256 open the door, can be expressed by equation (2):

T=S(E/L)(2)

Here the value of L is equal to the value J, which was mentioned in the guidelines. Button 256 door opening is oriented along the periphery of the annular frame door 209, and thus, the normal N of the shaft A directed toward the center from derno what about the block 208. Thus, it becomes possible to obtain a sufficient value of the distance F from the shaft A to the side wall 270 of the housing 202. Consequently, this allows you to set a larger value E is compared with the value K, which was mentioned in the guidelines. As a result, such a structure can reduce the magnitude of the pressure effort S to the user so that the force applied to the button 256 open the door without changing the force T is sufficient to influence the Executive mechanism 259.

Button 256 door opening is located in the upper right position of the annular frame 209 doors installed around the door unit 208, as shown in the front view front inclined surface A. Preferably, the button 256 door opener was located in an inclined position on the peripheral part of the annular frame 209 door, which was mentioned above. When you install button 256 inside the washing machine this configuration, it is even possible to increase the distance F to the side wall 270. This causes an increase in the value of the distance E from the Central pressure point G to the shaft A and, therefore, makes it possible to reduce the force required to press the button 256 open the door. In other words, it improves the efficiency of the washing machine drum t is PA.

It is preferable that the location of the button 256 door opening was oriented along the periphery of the annular frame 209 door. This arrangement is used in the case of configuration changes, so it can be easily realized by replacing the framing frame 209 in the part corresponding to the button 256 open the door. This contributes to the diversion of thoughts about the alteration of the outer inclined surface A side top front view of the housing 202, which is one of the major components and, consequently, leads to expansion of the applicability with the diversification of design.

In the future, it is preferable that the button 256 door opener was installed in a so-called frame so that the length in the direction along the periphery of the door block 208 was greater than the length in the radial direction of the door block 208. Such framing could help expand the full size button 256 open the door. Even in this case, the button 256 opening the doors framing able to influence the opening/closing actuator 293, because the normal shaft A directed toward the center of the door block 208. Button 256 door opening size can reduce the control effort required for operation of the buttons 256 open the door. In addition, even when the user clicks the end button 256 door opener instead of a Central push efforts G, the distance E is not changed. This has a stabilizing effect on the force's even a button 256 door opener, made with a large width to improve the practicability.

The above-described design of the device 259 lock is intended to be illustrative and not restrictive. The invention can be implemented in many other ways as much as working the design into a coherent movement with opening/closing actuator 293, or how much compression force applied on the button 256 door opener, performs the function of opening the door block 208 from the closed position.

As described above, the washing machine drum of the present invention has the advantage of reducing the pressure of the effort required for application to the button opening the door, along with the fact that this reduces loss efforts. The present invention can also be adapted in numerous applications, such as drying drum type, and similar devices, are equipped with locking mechanisms of the doors.

SUBSTANCE: laundry washer of drum type consists of case, of washing drum functioning as drying hopper, of door block, of door opening button, of opening/closing actuating device and of locking device. The case has an aperture on its front side. The door block of a round shape closes the aperture of the case. The door opening button is equipped with the first pivoting shaft, the opening/closing actuating device is equipped with the second pivoting shaft and the device is designed to turn under hold down force applied to the door opening button. In the position of aperture case closing the locking device for fixation of the door block operates in interconnected motion with the opening/closing actuating device, and it releases the door block changing its closed state to an open one under hold down force applied the door opening button. The door block is oriented so, that normal of the first pivoting shaft is inclined relative to the second pivoting shaft and is directed to the centre of the door block.

EFFECT: facilitating high controllability of laundry washer due to decreased hold down force applied to control button.

SUBSTANCE: washing-wringing machine comprises external drum, inside of which there is an internal drum installed coaxially with the possibility of horizontal rotation around axis of symmetry, as well as drive, suspensions and balancing device. Balancing device of washing-wringing machine consists of balancing ring rigidly installed on external surface of outer drum and two flat guides. One of guides is located in inner space of balancing ring and is rigidly fixed on shaft of inner drum, and the other guide is rigidly fixed on drive shaft. Balancing device also comprises balancing shaft, installed with the possibility of transverse motion relative to axis of machine symmetry by means of sliders fixed in its ends and installed with the possibility of displacement in according guides. Through threaded holes are arranged on shaft in mutually perpendicular planes at a distance to each other, one with right thread, other - with left thread. Longitudinal screw-shaped element passes through each of holes. On each of guides there are two support elements for fixation of screws. On each end of screws there is a disk fixed rigidly symmetrically to axis of rotation and with the possibility to contact to surface of balancing ring.

EFFECT: improved operational characteristics of machine due to reduced dynamic loads that occur as a result of imbalance.
