The present invention relates to a drum dryer.

Known drum dryer condenser type includes a closed loop of the drying air is made with the possibility of the circulation of heated drying air through the rotating drum, and air-cooled condenser, i.e. the heat exchanger air-to-air, are designed to remove moisture from the moisture-saturated hot drying air exiting mentioned drum, and an open path of cooling air is made with the possibility of the circulation of cooling air taken from the environment, through the air-cooled condenser for cooling the above-mentioned capacitor and for production of the cooling air flow again into the environment.

Example drum dryer of the above-mentioned type is schematically represented in figure 1.

Through the closed loop of the drying air is hot and saturated with moisture of the drying air comes out of the rotating drum and is conveyed to the air-cooled condenser. Then dehydrated drying air discharged from the condenser after the subsequent heating sent back into the drum to further remove moisture from clothes, perevorachivaesh inside the drum.

After cooled air Conde is Satori provides a means of heating the dehydrated drying air to send it back into the drum.

Air condenser contains many channels for the fluid, which may leak drying the air to condense and remove the moisture from it, and these channels for fluid surrounded by a cooling air flow flowing through an open path of the cooling air.

Closed loop drying air usually involves nodes filtering and collecting fluff, designed to remove lint from the drying air. This means filtering is required to prevent deposition of lint or cotton fibers and their accumulation on heat transfer surfaces of the air condenser, which can affect its performance and efficiency. In addition, this tool filtering prevents dangerous accumulation of lint on the heating means, which eliminates the possibility of fire.

However, the filtering means has a big drawback consisting in the fact that it can easily become clogged during drying, resulting in significant pressure losses in the circuit draining and therefore requires a corresponding increase in power to achieve the specified rate of flow through this path of drainage. This also occurs a significant change of the flow velocity in the drying process, which reduces the efficiency.

Another disadvantage is the fact that the security is of the highest possible efficiency of drum dryer, the user must after the end of each drying cycle to clean the filtering.

However, users typically do not want to do this routine work, care and cleaning, because it is required to perform certain actions, i.e. to come into contact with down and fiber. In addition, the user usually thinks it is a waste of time. It should be emphasized that the full effectiveness and ability to ensure performance drum dryers depend on technical service actually provided by the user. Thus, the consequences of poor service or maintenance performed not as often as required, are quite obvious.

But Pooh is inevitably delayed by the filter tool during the drying process, and this Pooh inevitably gradually increases the resistance to flow through the drying air, resulting in the flow rate of process air is somehow reduced, and the drying time required for the end of the current cycle, respectively, increases.

The present invention is to solve the above-mentioned problems, eliminating the drawbacks of the above known device.

In accordance with the present invention this problem along with other problems that will become apparent from the following description, which is settled in barabanschike for linen, features which are defined and represented in the attached claims.

In addition, the means of keeping and collecting fibers contain a means of draining for the collection containing the Pooh water on the lower section deflecting the air flow surface 7.

Preferably, the dryer has a cover 3 for closing and opening the end of the rotating drum. This cover 3 forms an air channel 4 closed loop of the drying air.

In other words, the air channel 4 closed loop drying air is formed in the lid 3, which essentially closes the open end of the rotating drum.

Drum dryer includes an external housing 11, i.e. the outer casing, the closing parts of the device. The outer casing 11 includes a window 12 loading/unloading with a door 13 that enables the load of Laundry inside and remove it from the drum. A drum installed inside the housing 11 for rotation around its Central axis with a drive from the engine.

Through the closed loop of the drying air is hot and saturated with moisture of the drying air comes out of the rotating drum and is fed in the direction of the air condenser 2. Then coming out of the condenser 2 dehydrated drying air after the heat again enters the drum to further remove moisture from clothes, perevorachivaesh inside the drum. Drum dryer contains suitable the fan to circulate the drying air in the closed loop of the drying air. The heating means is installed after the air condenser for heating the dehydrated drying air is again fed into the drum.

Open loop cooling air includes a fan to circulate cooling air through the condenser inlet and outlet openings for air, connected by a fluid environment with an air condenser 2. The cooling air in an open loop cooling air is taken from the environment, served in the air condenser and, eventually, released again into the environment.

Air condenser 2, which preferably is a heat exchanger air-to-air, contains many channels for a fluid medium, along which may be drying air to condense and remove the moisture from it, and these channels for fluid surrounded by a cooling air flow flowing through an open path of the cooling air.

For example, the condenser 2 may contain a first set of spaced apart channels for the fluid, which is passed the drying air, and a second set of spaced apart channels for the fluid, which is passed the cooling air and which are interleaved relative to the channels mentioned in the first set for a fluid with the food, in the result between two adjacent channels in the drying air is a channel for cooling air.

The cooling air flowing through the channels of the second set, wrap around, that is, moves in contact with the channels for the drying air, cooling it, causing the water vapor in the hot saturated with moisture, the drying air accumulate due to condensation.

The dryer includes means 14, 15, 16, 17, 18 for collection of air condenser 2 which is formed during operation of the dryer of the condensed water.

The cover 3 is made with the possibility of closing the open end of the drum and forming the air channel 4, which is a single plot of the closed loop of the drying air and is configured to transmit and receive coming out of the dryer the moisture-saturated hot drying air. In the air duct 4 has an inlet 5 that communicates through a fluid environment with the drum, the outlet 6 that communicates through a fluid environment with an air condenser 2, and deflecting the air flow surface 7 to reject entering into the inlet 5 of the air flow and feed it in the direction of the outlet 6 from which air is supplied to the air condenser 2.

The drum may be made in the form of a uniform design that represents the item that contains asuu cylindrical wall, front flange with a hole for providing access to the interior of the drum and the rear flange is mechanically connected to the drive shaft of the drum in rotation. In this case, the cover 3 is connected with the door 13 of the housing or integrated in it, with the possibility of closing the holes for access to the interior of the drum when the door is closed housing. Typically, the cover 3 is located on the inner side of the door 13 of the housing and directed to the inside of the drum so that the inlet 5 of the air channel 4 is located in close proximity to the access hole on the inside of the drum or may be installed inside the said hole when the door is closed 13 of the housing.

Alternatively, forming the air channel 4 cover 3 can be made so that it will fit the rear flange of the drum.

In an additional embodiment of the invention, the drum may consist of a cylindrical side wall, an open front and rear ends. The cylindrical side wall is mounted for rotation on the front and rear holders, which close the respective ends of the drum, allowing the cylindrical side wall to rotate relative to the front and back covers, which are still installed with respect to the outer housing 11.

One of these holders forms a cover 3, which is I (possibly in cooperation with the Cabinet door in its closed position) forms an air channel 4.

Tool 8 water supply may, for example, contain the means of irrigation, for example a tube, a spray or the like, which preferably has a lot of holes) made with the possibility of formation of water flow in close proximity to the upper part of deflecting the air flow surface 7 for the formation of a water film or veil 9, flowing down along deflecting the air flow surface 7. The drying air flowing during operation of the drum dryers are formed through the cover 3 air channel 4 as a result of collision with such a water film or curtain 9 is deflected and moves along it. Thus, entering into contact with the drying air and impurities, portable together with him, the water can catch and hold the Pooh and the fibers carried by the flow of drying air, which is thus cleared from these impurities and then exits the air channel 4 for its submission, that is moving in the direction of the air condenser.

The above-mentioned tool 10 plum may, for example, to include the site collection containing the Pooh water on the lower section deflecting the air flow surface 7.

Usually the drying air enters the air duct 4 through the inlet 5 and hits the water layer or veil 9, flowing down along deflecting the flow of ozdoba surface 7. This water film or veil 9 acts as a reflective wall, with which the drying air is faced with rejection and then moves in contact with this water film or veil 9. Water keeps typically transferred together with the drying air impurities such as fluff and fiber, while the tool 10 drain collects containing the Pooh water in close proximity to the lower section of deflecting the air flow surface. Thus, after cleaning and drying air from migrating them down, the drying air at the end of the air duct 4 through the outlet 6 is adjudged to be in an air condenser 2.

In one of the embodiments of the present invention, the cover 3 includes a tool 8 water supply and the tool 10 drain, and the tool 10 discharge, in particular, is located closer to deflecting the air flow surface. This option was preferred in the case when an open end of the cylindrical side wall of the drum is mounted for rotation on the cover 3.

In an additional embodiment of the invention, as shown in Fig.2-6, the door 13 of the housing includes a cover 3 forming an air channel 4 and the tool 8 water supply and the tool 10 drain installed close to the frame 19, forming box 12 loading/unloading in the outer casing 11, so that when akriti the door 13 of the tool 8 water supply is located in close proximity to the upper part of deflecting the air and the surface 7, while the tool 10 drain is located in close proximity to the lower part of this surface 7.

In particular, in the upper part of the frame 19 is installed, the tool 8 water supply, while in the bottom frame 19 is formed of the node 20 of the delivery or collection means 10 plum.

Accordingly, in the frame 19 is additionally made a hole 21 through which purified from down the drying air discharged from the air duct 4 through the outlet 6, can go directly into the air condenser 2, as shown in figure 2, 4 and 5, or may flow into the air condenser 2 when the fan 22.

The node 20 of the collection and the opening 21 are located and designed to prevent accidental capture containing the Pooh water and the transfer of the drying air in the air condenser 2.

Preferably, the tool 8 water supply reported in a fluid environment with the tools 14, 15, 16, 17, 18 of the collection, resulting in tool 8 water flows condensed water is then collected in the above-mentioned means 14, 15, 16, 17, 18 of the collection.

Additionally, the tool 10 plum is also reported in a fluid environment with the mentioned tool 14, 15, 16, 17, 18 of the collection, resulting in containing the Pooh water can be transferred to gather in the means 14, 15, 16, 17, 18 of the collection.

Preferably, the tool 8 water supply means 10 and drain means 14, 15, 16, 17, 18 collection form a closed loop water resulting in water entering the tool 10 plum and coming out of it, can be restored and re-filed with the tool 8 in the water supply.

A closed water circuit may include means 23 of the filter, configured to filter containing the Pooh water coming from 10 drain, resulting in tool 8 water supply may be filed filtered, fully purified from down the water.

Preferably, such means 23 set filter means 14, 15, 16, 17, 18 of the collection.

Means 14, 15, 16, 17, 18 collection may include any removable tanks, i.e. tanks, which can be extracted from the outer case 11, in which there are means 23 of the filter, either permanently installed tanks in which there is a removable tool 23 of the filter so that it can be removed for cleaning.

In the embodiment of the invention shown in figure 2 and 3, the tool 8 water supply is connected through a supply pipe 24 with the tool 14 collection, which includes a removable reservoir with means 23 of the filter. Located in the tool 14 collect the first valve 25 allows removable plug means 14 collection to the supply pipe 24, while placed there the second valve 26 provides for the filing of the condensed water from the air to the of tensator 2 in the tool 14 collection. Return line 27 connects the tool 20 drain tool 14 collection through the third valve 28 installed inside the means 14 collection.

The means 23 of the filter separates the tool 14 collection at first compartment 29 which has a capability of collecting coming from air condenser 2 of the condensed water, and the second compartment 30, is configured to collect funds resulting from 10 plum containing the Pooh water. Because the first compartment 29 is connected with the feed pipe means 24 8 water supply, the water in the second compartment 30 flows through the tool 23 of the filter (which holds therein the Pooh) and, ultimately, flows into the first compartment 29, and from thence to the tool 8 water supply through the supply pipe 24.

To circulate water in a closed circuit formed by the tool 8 water supply means 10 and drain means 14, 15, 16, 17, 18 collection, there is a pump 31.

Accumulated in the tool 23 filtering fluff can be removed by simply emptying the tank 14 through the hole made in the second compartment 30. Thus, pouring water in the second compartment 30 as a result of leaking water from the first compartment 29 during operation of the dryer allows you to remove and collect the Pooh, settled in the tool 23 of the filter.

4 shows an additional variant of the implementation of this is bretania, in which similar or identical parts and parts are denoted by the same numbers of reference positions.

In this particular case collection tool includes a stationary mounted tank 15, which are impossible to remove from the outer case 11 and in which the tool is installed 23 filtering. The said tank is communicated in fluid with the tool 8 feed means 10 drain and air condenser 2, in the same way as described above.

The collection tool additionally includes a container 16 that is installed with the possibility of removal in the upper part of the outer case 11 and connected to the feed pipe 24.

If necessary, the election of the feed water flowing through the supply pipe 24 to the tool 8 water supply and/or in the removable container 16, the valve 32 is set.

Preferably, in still installed tanks 15 may be made removable means 23 of the filter, which can be removed for cleaning.

Figure 5 shows an additional variant of implementation of the present invention, in which similar or identical parts and parts are denoted by the same numbers of reference positions.

In this case, the tool collection includes a stationary mounted tank 17, which cannot be removed from the outer case 11 and which is reported by those who UCA environment tool 8 filing the tool 10 drain and air condenser 2, in the same way as described above. This allows you to get in the tank 17 as condensed water coming from the air condenser 2, and containing the Pooh water coming from 10 plum.

The collection tool additionally includes a container 18, which is installed with the possibility of removal in the upper part of the outer case 11 and which is connected to the reservoir 17 through a connecting pipe 33, and with the tool 8 water flow through the supply pipe 24. The container 18 includes means 23 of the filter, configured to filter flowing through it is fed into the tool 8 in the water supply. The means 23 of the filter installed in the container 18 so that it essentially forms a first compartment 34, which receive water from the reservoir 17, and the second compartment 35 into which the filtered water to flow through the supply pipe 24 to the tool feed water.

Accumulated in the tool 23 filtering fluff can be removed by simply emptying the container 18 through the opening in the first compartment 34. Thus, the pouring of water from compartment 34 located therein as a result of leaking from the second compartment 35 during operation of the dryer allows you to remove and collect the Pooh, settled in the tool 23 of the filter.

Figure 6 shows another Odie the additional option of implementing the present invention, which is essentially similar to the one shown in figure 2 and 3. The only difference is that cleared down the drying air discharged from the air channel 4, first enters the fan 22, and then is served and accordingly is directed to an air condenser 2.

Regarding option, shown in figure 2 and 3, the drum of the dryer in accordance with the present invention uses a pump 31 which pumps out contained in the tank 14 water (through the first valve 25) for feeding into the tool 8 water supply through the supply pipe 24. Flowing along deflecting the air flow surface 7 of the water in the form of a water film or veil 9 captures and holds the Pooh, carried by the flow of drying air, removing it from the air. Contains fluff, water is collected in the node 20 of the collecting means 10 and drain through the return pipe 27 enters the tank 14. Through the third valve 28 containing the Pooh water enters the second compartment 30 of the tank 14 and then passes through the means 23 of the filter in the first compartment 29 of the tank 14, from which it is drawn through the first valve 25 by the pump 31.

Condensed in overhead condenser 2 water, in turn, can be replenished through the second valve 26) of the first compartment 29 from which it is drawn through the first valve 25 by the pump 31.

Water plenary veil 9 can act during the entire drying cycle, in this case, you just need to ensure that the tank 14 has never been completely emptied, and the specified amount of water, or otherwise, shall remain in the tank 14. Alternatively, because the fluff begins to form after downloaded linen in the dryer to dry to a certain extent, there is no need for the inclusion of a water film or veil from the beginning of the drying cycle. In fact, it is enough to activate a water film or veil after a certain period of time after the start of the drying cycle. This mode has the advantage that the water film or veil may be formed using the condensed water, which by this time may accumulate in the tank 14.

The mode of operation of drum dryer in an embodiment in figure 4 is essentially similar to the mode described above. The only difference is that water is pumped by pump 31 from a permanently mounted tank 15 may be selectively submitted (through the corresponding valve 32 in the tool 8 water supply and/or removable container 16.

The work drum dryer in an embodiment according to figure 5, based on the collection still in the established tank 17 condensed water from an air condenser 2, and containing the Pooh water coming from the return of the pipeline is an ode to 27 tools 10 drain. The pump 31 selects the water from the tank 17 and delivers it (through appropriate piping 33) in the first compartment 34 of the removable container 18. Then, by passing through the tool 23 of the filter, which acts as a baffle, the water enters the second compartment 35 of the container 18, and is supplied through the supply pipe 24 to the tool 8 in the water supply.

Thus, the present invention containing nodes deduction and collection fibers, allows you to effectively ensure that the drum of the dryer without changing its characteristics during the drying cycle, i.e., the performance level of drum dryer remains unchanged during the drying cycle. This is due to the fact that the present invention can prevent the formation of obstacles, which would be resistance to the flow of process air through the closed loop of the drying air.

In addition, units retention and collection fibers in accordance with the present invention does not require any special maintenance that should be performed by the user.

It should be emphasized that the only reason you use the 23 filter containing the Pooh water, is to improve the ability of a water film or veil 9 to catch and hold the Pooh as a whole and to minimize the risk for the orenia closed water circuit in the drying process. However, the use of such filtering should not be regarded as binding.

In addition, when such means 23 of the filter installed in removable containers 14 and 18, it is only required just to empty these containers (what to do in any case) for purification means 23 of the filter.

SUBSTANCE: according to proposed method, after preliminary removal of moisture by centrifuging, linen is acted upon by elastic vibrations of ultrasonic frequency. Said vibrations are formed by aerodynamic or electromechanical converters and are introduced into linen to be dried contactlessly through nonresonance air gaps or through design members of washing machine. Intensity of elastic vibrations is set within 135 and 160 dB. Frequency of vibrations is chosen to provide acoustic resonance of inner volume of washing machine tumbler and/or inner air gap between tumbler for linen and outer tumbler. In process of drying frequency is changed according to change in quantity of linen to be dried and its moisture content. Owing to use of optimum sources of ultrasonic vibrations and corrected parameters and conditions of formation and introduction of vibrations into linen, energy consumption for implementing the method is reduced.
