Description

Clothes treating apparatus

Technical Field

The utility model relates to the technical field of clothes treatment devices, and particularly provides a clothes treatment device.

Background

The existing condensing type clothes drying device utilizes hot air to exchange heat with clothes, so that moisture in the clothes is evaporated, and the effect of quick drying is achieved. During the drying process, the moisture on the clothes is taken away along with the hot air and mixed into the air. In order to separate out the moisture-containing air, it is generally necessary to cool down the air by means of a condenser, separate the moisture from the air, finally form condensed water, and then drain the condensed water through a drain channel.

However, although such a drying apparatus is seemingly simple and easy to use, there are problems in use, one of which is the problem of condensed water discharge. Once the condensate water drainage channel is blocked, condensate water cannot be normally drained. With the continuous drying, the accumulated condensed water is increased, and finally the condensed water flows back to the clothes placement position, so that the clothes are soaked, and the drying failure is caused.

Accordingly, there is a need in the art for a laundry treating apparatus to solve the above-mentioned problems.

In order to solve the problem that condensed water which cannot be discharged during drying flows backwards to soak clothes, the embodiment discloses a clothes treatment device, in particular to a washing machine with a drying function, which is mainly used for drying the clothes and can also be used for washing the clothes.

It should be noted that although the laundry treatment apparatus in the present embodiment is a washing machine having a drying function, this is not a limitation of the present utility model, and other types of laundry treatment apparatuses may be adopted in other embodiments by those skilled in the art without departing from the principles of the present utility model, such as: the clothes treating apparatus is only a clothes drying apparatus, and does not have a function of washing clothes; alternatively, the laundry treating apparatus is another laundry treating apparatus having a drying function. All without departing from the basic principles of the utility model and therefore fall within the scope of the utility model.

Referring to fig. 1, the laundry treating apparatus includes a drum assembly 1, a dryer 2, a condenser 3, a drain assembly 4, a water level detecting member, an alarm, and a controller.

The drum assembly 1 is used for placing wet laundry to be dried. Specifically, the drum assembly 1 includes an outer tub 11 and an inner tub 12, the inner tub 12 being disposed within the outer tub 11, and the inner tub 12 being rotatably connected to the outer tub 11. The clothes are placed in the inner cylinder 12, and the inner cylinder 12 can drive the clothes to turn over, so that the clothes are uniformly and fully contacted with hot air, and the drying efficiency is improved. The outer tub 11 and the inner tub 12 are provided with openings on the same side for putting in or taking out laundry. In the present embodiment, the drum assembly 1 is also capable of washing laundry. However, this is not a limitation of the present utility model, and in other embodiments, the drum assembly 1 may be used only for drying laundry.

The dryer 2 is capable of heating air and delivering the heated air into the drum assembly 1. Specifically, the air outlet of the dryer 2 communicates with the drum assembly 1. More specifically, the air outlet of the dryer 2 is disposed toward the opening of the inner tub 12 to enable hot air to enter the inner tub 12. The hot air contacts the wet laundry in the inner tub 12, and moisture on the wet laundry absorbs heat in the hot air to evaporate and mix the moisture into the air. The structure of the dryer 2 is the same as that of a conventional drying device of a washing machine with a drying function in the prior art, and the specific structure thereof is not described herein.

The condenser 3 is used to reduce the temperature of the air so that the water vapor in the air condenses into water. Specifically, the condenser 3 includes an exhaust portion 31 and a cooling portion 32. The exhaust part 31 communicates with the drum assembly 1 so that air mixed with water vapor in the drum assembly 1 can enter the exhaust part 31; and the exhaust part 31 is also communicated with an air inlet of the dryer 2 so that the air cooled in the exhaust part 31 can enter the dryer 2, thereby forming a circulating air flow. The cooling portion 32 is provided with coolant water therein, and the coolant water has a low temperature. The air in the exhaust part 31 and the refrigerant water in the cooling part 32 can exchange heat so as to cool the air in the exhaust part 31 and enable water vapor in the air to be condensed and then remain in the exhaust part 31. Further, the cooling portion 32 communicates with a water supply device, which can supply low-temperature coolant water like the cooling portion 32, so that the cooling portion 32 can cool the hot air in the exhaust portion 31 and water vapor in the air. Wherein the water supply device is specifically a tap water pipeline.

The drain assembly 4 is used to drain condensed water in the exhaust portion 31. Specifically, the drain assembly 4 includes a drain pipe 41, a filter 43, and a drain pump 42.

The drain pipe 41 communicates the exhaust part 31 with the outside of the laundry treating apparatus so that condensed water in the exhaust part 31 can be discharged to the outside of the laundry treating apparatus through the drain pipe 41. In the present embodiment, the drain pipe 41 is also used to drain the washing water in the drum assembly 1 when the drum assembly 1 performs washing of laundry; in other embodiments, the drum assembly 1 communicates with a separate pipe for discharging the washing water, and is not discharged through the drain pipe 41 of the drain assembly 4.

A filter 43 is provided on the drain pipe 41 for filtering lint or other impurities in the running water in the drain pipe 41.

The drain pump 42 is disposed on the drain pipe 41. The drain pump 42 is capable of supplying power, sucking condensed water in the exhaust part 31 into the drain pipe 41, and discharging water in the drain pipe 41 out of the laundry treating apparatus.

Further, the cooling part 32 communicates with the drain pipe 41 so that the heat-exchanged refrigerant water in the cooling part 32 can be sucked to the drain pipe 41 by the drain pump 42 and discharged.

It should be noted that, although the cooling portion 32 in the present embodiment discharges the coolant through the communicating drain pipe 41, the present utility model is not limited to this structure, and those skilled in the art can adopt other arrangements in other embodiments without departing from the principles of the present utility model, for example: the cooling part 32 can be provided with a drain pipe independently, so that the chilled water can be drained independently, and the chilled water is prevented from being mixed into condensed water; alternatively, the cooling unit 32 may be connected to the drain pipe 41 downstream of the filter 43, and no filtering is required because the coolant water is free of impurities such as lint. These arrangements do not deviate from the basic principle of the present utility model and therefore fall within the scope of the present utility model.

The water level detecting member, specifically, a water level sensor, can acquire the level of condensed water in the exhaust portion 31. Specifically, the exhaust portion 31 of the condenser 3 is provided with a bypass pipe so that the liquid level in the bypass pipe is the same as the condensed water level in the exhaust portion 31. More specifically, the bottom end of the exhaust part 31 is connected to the lower end of the bypass pipe, and the upper end of the bypass pipe is provided with an opening so that the exhaust part 31 and the bypass pipe constitute a U-shaped pipe, and the level of the liquid in the bypass pipe is the same as the level of the condensed water in the exhaust part 31. The water level detecting member can obtain the condensed water level in the exhaust portion 31 by obtaining the liquid level in the bypass pipe. In other embodiments, the water level detecting member may be provided in the exhaust portion 31 so as to directly acquire the condensed water level in the exhaust portion 31.

The alarm is used for indicating that the condensed water level in the exhaust part 31 is too high. Specifically, the alarm includes a horn and/or a warning lamp, and when the condensed water level in the exhaust portion 31 is too high, the horn sounds an alarm, and the warning lamp lights up or blinks, thereby reminding the user. In other embodiments, the alarm may also be integrated into a display module of the laundry treatment apparatus, and when the condensate level in the exhaust portion 31 is too high, a notification message of "condensate level in the exhaust portion 31 is too high" is displayed on the display module.

The water level detection part, the alarm, the drainage assembly 4 and the dryer 2 are all electrically connected with the controller. The controller can control the operation of the alarm, the drainage assembly 4 and the dryer 2 along with the condensed water level obtained by the water level detection part. Specifically, the water level detecting element detects the level of the condensed water in the exhaust part 31, and sends the level of the condensed water to the controller, the controller judges whether the level of the condensed water reaches a second preset level, if the level of the condensed water reaches the second preset level, the level of the condensed water in the exhaust part 31 is higher, in other words, the filter 43 is blocked, the condensed water in the exhaust part 31 cannot be discharged, and accumulation occurs; or the flow rate of the condensed water in the exhaust portion 31 becomes slow and cannot be discharged in time. The controller drives the drain pump 42 to be activated to power the condensed water in the drain pipe 41 and the drain portion 31 so as to be discharged.

Further, the controller can also judge whether the condensed water level reaches a first preset level, and the first preset level is higher than a second preset level. If the condensate level reaches a first preset level, representing that the condensate level is too high, possibly flowing backwards into the drum assembly 1 to wet the laundry, the controller drives the alarm to start, reminding the user to clean the filter 43 so as to drain the condensate. And, the controller drives the dryer 2 to be turned off, thereby preventing the condensed water in the exhaust portion 31 from continuously increasing.

The controller is configured to perform the control method of the laundry treating apparatus described above, specifically, to control the alarm, the drain pump 42, and the dryer 2 according to the condensed water level. The control module may be configured to perform only the control method, and not perform other operation control of the laundry treating apparatus, and other operation control may be further equipped with other control modules; it may be configured to perform other operation control of the laundry treating apparatus in addition to the control method, that is, the control module is an integrated execution module, that is, to execute each program in the operation of the air conditioner.

The operation principle of the laundry treating apparatus will be described in detail.

The dryer 2 heats air and delivers the heated air into the drum assembly 1 so that the heated air exchanges heat with laundry in the drum assembly 1, and moisture on the laundry is evaporated by heat absorption and mixed into the air, thereby drying the laundry. The dryer 2 continuously delivers hot air to the drum assembly 1 so that the air mixed with the water vapor enters the exhaust part 31 of the condenser 3. The low-temperature refrigerant water in the cooling portion 32 of the condenser 3 exchanges heat with air in the exhaust portion 31 to cool the air, and moisture in the air is condensed into liquid water to remain in the exhaust portion 31. The cooled air enters the dryer 2 to be heated, and then enters the roller assembly 1 again to be dried.

The level of condensed water in the air discharge portion 31 can be discharged to the outside of the laundry treating apparatus through the drain pipe 41, and the filter 43 on the drain pipe 41 can filter lint or other impurities in the condensed water. As the impurities collected on the filter 43 become more and more, the condensed water in the exhaust part 31 will hardly pass through the filter 43, but will be accumulated in the exhaust part 31 and the drain pipe 41.

The water level detecting member can acquire the level of the condensed water in the air discharging portion 31 and deliver the level to the controller. Referring to fig. 2, the controller performs the following control method:

s1: acquiring the condensed water level in the exhaust portion 31;

s2: the on and off states of the alarm, the drain pump 42, and the dryer 2 are controlled according to the condensed water level.

Referring to fig. 3, the control method specifically includes the steps of:

s101: the condensed water level in the exhaust part 31 is acquired by the water level detecting member, and then S102 is performed.

S102: judging whether the liquid level reaches a second preset liquid level, if not, representing that the liquid level is lower, the condensed water in the exhaust part 31 is less retained or the filter 43 is circulated, the clothes treating apparatus can continue to work, and S101 is executed again; if the second preset liquid level is reached, the liquid level is higher, and the filter 43 is blocked, so that condensed water in the exhaust part 31 cannot be discharged and accumulated; or the flow speed of the condensed water in the exhaust part 31 becomes slow and cannot be discharged in time, S103 is executed.

S103: judging whether the liquid level reaches a first preset liquid level, wherein the first preset liquid level is a dangerous liquid level, and when the condensed water in the exhaust part 31 exceeds the first preset liquid level, representing that the condensed water possibly flows back into the roller and wets clothes, so that the drying failure is caused. Therefore, if the liquid level does not reach the first preset liquid level, indicating that the liquid level is low, S104 is performed; if the liquid level reaches the first preset liquid level, S105 is performed.

S104: the drain pump 42 is activated to power the condensed water in the exhaust part 31 to be discharged to the outside of the laundry treating apparatus through the filter 43. Further, in S104, S106 is performed after the preset time elapses when the drain pump 42 is started.

S105: the dryer 2 is stopped, and an alarm is activated to prompt the user that the condensed water level in the exhaust portion 31 is too high and the filter 43 should be cleaned so as to discharge the condensed water.

S106: the drain pump 42 is turned off, and S101 is performed again.

Thus far, the technical solution of the present utility model has been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of protection of the present utility model is not limited to these specific embodiments. Equivalent modifications and substitutions for related technical features may be made by those skilled in the art without departing from the principles of the present utility model, and such modifications and substitutions will fall within the scope of the present utility model.
