The present invention relates to a machine for drying clothes.

In the dryer important characteristic is the ability to measure the degree of dryness of clothes for appropriate regulation of the length of the drying cycle. Typically, the dryer is equipped with an electrical circuit for measuring the residual moisture content in lingerie on the basis of the electrical conductivity or resistance. This circuit is arranged to measure the moisture content usually contains electrically conductive contact strip located on the annular wall of the dryer drum. This strip is electrically isolated from the reel non-conductive plate connected to the drum and located between the band and the drum. On the other hand, the band has electrical connection with the electrodes, i.e. the electrical pins on the lifting underwear ribs or means of lifting underwear, located on the inner surface of the circular wall of the drum.

Electrodes made with the possibility of contact with the Laundry inside the drum when it is flipped during rotation of the drum, and the electrodes are properly insulated from the metallic inner surface of the circular wall of the drum by a non-conductive elements.

On the body is down a set readout console located on the brush, which has the possibility of engagement with the conductive strip. Itself brush electrically connected to the control unit, which is also electrically connected to the metal inner surface of the annular wall of the drum, serving as the electrical output of this circuit.

Wet clothes inside the drum provides the electrical connection of the electrodes on the means of lifting linen with metallic inner surface of the drum and thereby closes the circuit.

Usually wet underwear connects the electrical leads of the circuit, that is, the electrodes on one side and the metal inner surface of the drum with the other hand.

When the circuit is supplied with electric current, it can flow through wet clothes to be dried, and the control unit in the machine can calculate the resistance and/or conductivity of the sheets and thereby to determine the necessary duration of the drying cycle.

As linen is flipped inside the drum, it constantly falls on the metal inner surface of the drum, while the heavier elements of underwear, such as buttons, zippers and other metal or, at least, solid accessories that can be coupled with the exposed drying clothes or freely hanging in the midst of it (such as coins), tend to hit Metallichesky inner surface and create noise in the drying process. In addition, a metal drum works in this case as a resonance chamber, so that the level of the created thus noise, ultimately increases.

Thus, there is a need to reduce the noises generated linen and other items, tumbling inside the dryer drum.

To compensate for or reduce noise generated linen and other items, tumbling in the dryer drum, currently use a sheet of foam plastic, such as polypropylene foam, which as insulating means is covered with a metal inner surface of the drum, or even use the dryer, which is completely made from such polymeric materials, such as resin or plastic, which by its nature is effective at damping noise.

However, both of these solutions sound have the disadvantage that the inner surface of the drum becomes electrically non-conductive, since polymeric materials are electrical insulators.

In this case, the above-described electrical circuit used to measure the residual moisture content at the drying unable to work, because the inner surface of the annular wall of the drum is due to the fact that it is electrically continuous is oodama - may not act as an electrical output that is not able to function as the electrical contact of the circuit, subject to connection through clothes with other electrical conclusions of this chain, that is, electrodes placed on the means of lifting the clothes inside the drum.

Thus the main objective of the present invention is to provide a drying machine, which allows to overcome the aforementioned disadvantages of the known dryers.

According to the present invention is tasked, along with additional tasks, which will become apparent from the following description, removed in a drying machine, the characteristics of which are set out in the claims.

The characteristics and advantages of the present invention will be clearer from the description given below as a non-limiting example with reference to the accompanying drawings.

figure 2 is an enlarged view of part of the drying machine shown in figure 1;

figure 3 is a perspective view of a dryer drum according to the present invention;

figure 4 is a perspective view of the drum of the drying machine according to the second variant of implementation of the present invention.

According to the above figures, the drying machine is on, denoted by reference number 1, includes a rotating drum 2, is made with the possibility of adopting and accepting and understanding of objects 3 sheets to be dried, one or more means 4 rise underwear, located on the inner annular surface 5 of the drum 2, and an electrical circuit for determining the resistance and/or conductivity of linen placed in a rotating drum 2.

Each tool 4 rise of the underwear contains at least one first electrode 6 and at least one second electrode 7 made with the possibility of contact with the Laundry, and the electrodes are electrically isolated from each other.

Around the outer annular surface 10 of the drum 2 are a first conductive contact element 8 and the second conductive contact element 9, which are electrically isolated from each other and electrically connected to the first electrode 6 and second electrode 7.

The first sliding contact 11 and the second sliding contact 12 are slidable along the first conducting contact element 8 and the second conducting contact element 9, respectively, in direct galvanic connection with them during the rotation of the drum 2.

With both sliding contacts 11, 12 are electrically connected to the control block 13 to measure the electrical parameter dependent residual llagosta is living in linen, tumbling in the drum and connecting the first and second electrodes 6, 7.

Drying machine includes an external casing made with the remote control of the machine, and the location therein of the rotating drum 2; a motor and fan.

This external enclosure is equipped with a door that allows the user to gain access to the interior of the drum through the access hole. The drum 2 is installed inside the housing for rotation around its Central axis to bring him in motion by an electric motor.

The drum 2 is located within the outer casing in the path of air flow that you can force feeding through him dry heated air to remove moisture from perevorachivaesh in there underwear.

The drum 2 may contain a side wall made of metal, in particular stainless steel, and covered inside with sound absorbing layer in the form of electrically non-conductive sheet, or it may contain a side wall made of an electrically non-conductive polymeric material. The last variant embodiment of the invention shown in the figures.

On the inner annular surface 5 of the side wall of the drum are one of several tools 4 rise underwear for proper turning subjected to drying Laundry in the drum 2.

The drum 2 may include a front flange 14 with made it by opening access to Laundry load and the rear flange 15 which is mechanically connected with the shaft around which can rotate the drum 2. The flanges 14, 15 can be made of metal and plastic and, in particular, as a unit with the side wall of the drum.

In another embodiment of the invention, the drum may include a cylindrical side wall that is open at the front and back of their ends. The cylindrical side wall is mounted for rotation on the front and rear supports so as to close the respective ends of the drum, while the cylindrical side wall has a possibility of rotation relative to the front and rear of the head elements, which are fixed with respect to the outer housing. Between the front pillar and a cylindrical side wall and a rear bearing and a cylindrical side wall are sealing elements permitting relative movement and prevent leakage.

Each tool 4 rise of the underwear contains at least one first electrode 6 and at least one second electrode 7, which are electrically isolated from each other and configured to contact with the Laundry inside the drum 2, when it is flipped during rotation this is drum 2. The first and second electrodes 6, 7 can be performed, for example, in the form of a pair of metal surfaces are electrically isolated from each other and connected externally with a support element, which in the preferred embodiment, is made of electrically non-conductive material and is located on the inner annular surface 5 of the drum 2,

It is obvious that the greater the length of such surfaces, the greater will be their ability to enter into contact with the exposed drying linen and, consequently, the greater will be the accuracy of the measurement of the conductivity of this lingerie, especially when this lingerie has already reached a relatively advanced stage of the drying process, i.e. it is already in an almost dry state or when the load of Laundry in the drum is relatively small.

The first electrode 6 each 4 lifting linen electrically connected to the first electrically conductive contact element 8 made of a metal strip located on the outer annular surface 10 of the drum 2. For this electrical connection has a first electrically conductive element 16, through the passage in the cylindrical wall of the drum 2 in accordance with the area of the drum 2, which is the first electrode 6 each 4 rise underwear. A first electrically conductive element 16 made the AET of the cylindrical wall of the drum 2 so, to implement and establish electrical contact with the metal strip of the first electrically conductive contact element 8.

Completely similarly the second electrode 7 each 4 lifting linen electrically connected with the second conductive contact element 9, which in turn are made of metal strips located on the outer annular surface 10 of the drum 2. The connection is provided by the second electrically conductive element 17, which passes through an additional channel, made in the cylindrical wall of the drum 2 in accordance with the area of the drum 2, which is the second electrode 7 of each lifting linen component 4. This second electrically conductive element 17 is of cylindrical wall of the drum so as to contact with the second electrically conductive contact element 9.

Electrically conductive elements 16, 17, passing through the wall of the drum, are located so as not to contact with each other, providing an effective electrical isolation between the first and second electrodes 6, 7.

Preferably, the first and second electrically conductive elements 16, 17 are made as a single unit with the first and second electrodes 6, 7, respectively, and may, for example, be a use the e tabs or the like, made so as to pass through the appropriate channels, speaking from the cylindrical wall of the drum 2 in the appropriate locations means 4 rise of linen.

If the drum 2 is made of electrically non-conductive material, such as polymeric plastics material, in fact there is no need to, the electrodes 6, 7 and the corresponding electrically conductive elements 16, 17 were electrically insulated from the drum 2.

If the drum 2 is made of metal, it is preferable that the electrodes 6, 7 are located on the support element, the lifting of linen, which in addition to providing adequate electrical insulation between the first electrode 6 and second electrode 7 is also provided to electrically isolate the electrodes 6, 7 from the drum 2. In addition, between each electrically conductive element 16, 17 and the corresponding passage in the wall of the drum, are insulating means to electrically isolate each electrically conductive element 16, 17 on the drum 2.

In a preferred embodiment of the present invention, each tool 4 rise of the underwear contains the first metallic section 6 and the second metal section 7, acting as the first and second electrode, respectively, which are located on the HV the internal annular surface 5 of the drum 2, separated and electrically isolated from each other by a dividing element 18. Preferably, each tool 4 lifting linen includes two metal halves 6, 7 are separated from each other by insulating separating element 18. These two halves 6, 7 can be arranged in one row along or across the axis of rotation of the drum, thus dividing element 18 is located between these two halves, as shown in figure 3 and 4.

If the drum 2 is made of metal, includes insulating means for electrically isolating the first and second metal half 6, 7 each 4 lifting linen drum 2. For this purpose, can be used absorbent sheet, which covered the inner annular surface 5 of the drum 2. In addition, there are additional insulating means to electrically isolate the electrically conductive elements 16, 17 of each of the metal half of 6, 7 the lifting underwear to the side, i.e. from the side of the circular metal wall made of metal drum 2.

It is obvious that when the drum 2 is made entirely of electrically non-conductive material, metal tools 4 lifting underwear directly connected with the inner annular surface 5 of the drum 2 without any inserted between the insulating them money.

Each conductive contact element 8, 9, which may, for example, be a metal strip or ribbon attached to the outer annular surface 10 of the drum 2 by means of suitable fastening means or adhesive bonding.

If the drum 2 is made of electrically conductive material, as a metal strip of each conductive contact elements 8, 9, and their associated mounting means are suitably electrically insulated from the drum 2 by means of an insulating means which must be properly placed between the various electrically conductive objects or elements.

For example, to provide the required electrical insulation between the drum 2 and the conductive contact elements 8, 9, between the receiving holes formed in the wall of the drum, and fastening means located in these holes, inserted electrically non-conductive elements, usually made of rubber or plastic, and between the outer annular surface of the drum 2, and a conductive contact element 8, 9 is plastic tape.

On the other hand, the desired insulating effect can be provided with a binder layer of insulating adhesive is virtually no other or additional insulating means is, inserted between the conductive contact elements 8, 9 and the drum 2.

It is also effective to provide electrical isolation from each other, the first conductive contact element 8 and the second conductive contact element 9.

In addition, according to the present invention is a machine for drying clothes also contains the first sliding contact 11, is made slidable on the first conducting contact element 8 in direct galvanic connection with him, and the second sliding contact 12, is made slidable on the second conducting contact element 9 in direct galvanic connection with him, during the rotation of the drum 2.

Sliding contacts 11, 12 are made of graphite, copper or similar material and preferably each of them is made in the form of the contact of the scraper or brush associated with the inner frame of the machine so as to keep unchanged, i.e. fixed position relative to the machine. Each such brush, that is, each sliding contact 11, 12, may be located, for example, on a reading of the console 19.

Each readout console 19 is installed on the machine body with the possibility of sliding engagement with the respective conductive contact elements 8, 9 and allows the first and second sliding contact 11And 12 to remain in a state of electrical contact, constantly supported with the first and second conductive contact element 8, 9, respectively, while these elements rotate together with the drum 2 during drying.

Both of the sliding contact 11, 12 electrically connected to the control block 13, forming an electrical circuit, configured to determine a change in the electrical conductivity and/or electrical resistance of the sheets to be processed in the rotary drum 2 during drying.

Thus, the above-mentioned electric circuit mainly contains the first line of contact, which includes the first electrode 6 each 4 rise of the underwear, the first conductive contact element 8 and the first sliding contact 11, and a second line of contact, which includes the second electrode 7 each 4 rise of the underwear, the second conductive contact element 9 and the second sliding contact 12, while these two lines of contact are connected to each other by means of block 13 of the control.

Wet clothes inside the drum provides electrical connection of the first electrode 6 each 4 rise underwear with the second electrode 7 each 4 lifting linen and thereby closes the circuit.

The control block 13 is arranged to provide power to the electrical circuit so that electrical current could flow through the electric circuit and, as a result, the e through a wet linen, located in the drum. Since the resistance or conductivity (depending on what is being measured) electrical circuit depends on the residual moisture in the Laundry to be dried, the control block 13 is able to continuously determine the degree of dryness of clothes in the time of the dryer to determine the end of the drying cycle, in which the drying operation is to be interrupted upon reaching the final degree of dryness selected by the user for the processing of linen.

In addition, it should be noted that the bonding layer and the conductive contact elements 8, 9 form a kind of sound-insulating lining, which is especially effective and benefits the absorption of the sound waves generated by the underwear incident on the metal wall of the drum or colliding with it the rotation of the latter, especially when such a wall collide with some solid objects, usually associated with the garment parts, such as buttons or zippers.

This gives a special advantage if the drum is made of metal, because the effect of attenuation of noise through non-conductive insulating sheet covering the inner metal surface of the drum.

Sound waves generated by the collision of the garment with the inner surface of the drum, the larger h is STU absorbed binder layer, which due to its viscoelastic properties to a significant extent converts these sound waves into heat, thereby heating the bonding layer.

On the other hand, sound waves are able to pass through the layer of glue and exit, passed in conductive contact elements 8, 9, where they are vulnerable to further weakening.

In the most preferred embodiment of the present invention conductive contact elements 8, 9 cover most of the outside annular surface 10 of the metal drum 2, so that the effect of the absorption of sound waves increases maximally. In practice, the conductive contact elements 8, 9 can be wound around the entire outer annular surface of the drum 2, while ensuring, of course, a proper electrical isolation between the first and second conductive contact elements 8, 9.

Thus, the machine for drying clothes according to the present invention allows to determine the electrical conductivity and/or electrical resistance of linen processed inside a rotating drum, even when the inner surface of the drum in contact with the linen, made of electrically non-conductive material.
