DETAILED DESCRIPTION

[0038] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the present invention, but the embodiments of the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0040] like Figures 1 to 6 As shown, this embodiment provides a clothes processing device, which includes a housing 1, a clothes processing drum 2 arranged in the housing 1, and a heat pump heat exchange component 3.

[0041] A heat exchange channel 4 is provided between the housing 1 and the laundry processing tub 2 . The heat exchange channel 4 is connected to the inner cavity of the laundry processing tub 2 . At least part of the heat pump heat exchange component 3 is arranged in the heat exchange channel 4 .

[0042] The air can circulate between the heat exchange channel 4 and the inner cavity of the clothing treatment drum 2. Since at least part of the heat pump heat exchange component 3 is arranged in the heat exchange channel 4, the air flow in the heat exchange channel 4 can exchange heat with the heat pump heat exchange component 3 when flowing through the heat pump heat exchange component 3, and then further flow into the inner cavity of the clothing treatment drum 2, so as to heat the clothes placed in the inner cavity of the clothing treatment drum 2 through the air flow after the heat exchange. Exemplarily, a circulating fan 5 can also be arranged in the heat exchange channel 4, and the circulating fan 5 can drive the air to circulate between the heat exchange channel 4 and the inner cavity of the clothing treatment drum 2.

[0043] Exemplarily, the heat pump heat exchange component 3 specifically includes an evaporator 31, a condenser 32 and a compressor 33. The evaporator 31 and the condenser 32 are both connected to the compressor 33, and the heat exchange medium 35 can circulate between the evaporator 31, the condenser 32 and the compressor 33. Exemplarily, the evaporator 31 and the condenser 32 are arranged in the heat exchange channel 4.

[0044] In a specific implementation, the heat pump heat exchange assembly 3 may further include an expansion device 34, through which the evaporator 31 and the condenser 32 are connected, so that after the compressor 33 stops running, the pressure in the condenser 32 and the evaporator 31 can automatically reach equilibrium quickly, thereby reducing the load at startup. The expansion device 34 is, for example, a capillary tube.

[0045] Reference Figure 2 As shown, when the heat pump heat exchange component 3 is working, the compressor 33 sucks in a low-pressure gaseous heat exchange medium 35 (such as a refrigerant), and the heat exchange medium 35 is compressed by the compressor 33 and discharged into the condenser 32 in a high-temperature and high-pressure gaseous state, and exchanges heat with the air entering the heat exchange channel 4. After the air is heated by the condenser 32, the heat exchange medium 35 is cooled and condensed by the air to form a high-pressure liquid, and then it is decompressed by the expansion device 34 to become a low-temperature and low-pressure gas-liquid two-phase mixture and enters the evaporator 31, and then exchanges heat with the air in the heat exchange channel 4. Specifically, the evaporator 31 absorbs heat from the air to condense the moisture in the air to achieve dehumidification, and then the heat exchange medium 35 of the gas-liquid two-phase mixture absorbs heat to become a gaseous low-temperature heat exchange medium 35 and is returned to the compressor 33 for pressurization, so as to achieve heat exchange.

[0046] The process of drying the clothes in the laundry treatment drum 2 by the heat pump heat exchange component 3 is as follows: the low-temperature humid air in the laundry treatment drum 2 enters the heat exchange channel 4 under the action of the circulation fan 5, and can first pass through the evaporator 31 to exchange heat with the evaporator 31, so that the evaporator 31 absorbs heat from the air to achieve air dehumidification. The dehumidified dry low-temperature air then passes through the condenser 32 for heat exchange to heat the air, and then enters the laundry treatment drum 2 after forming high-temperature dry hot air, thereby achieving heating or drying of the clothes in the laundry treatment drum 2.

[0047] The clothing processing device further includes a heat exchanger 6 , at least a portion of which is disposed in the heat exchange channel 4 , and the heat exchanger 6 is used to absorb a portion of the heat of the air in the heat exchange channel 4 .

[0048] Exemplarily, when the clothes processing device dries the clothes in the inner cavity of the clothes processing drum 2, the clothes processing device sequentially undergoes the following three stages:

[0049] The first stage is the preheating stage. In this stage, the heat energy provided by the heat pump heat exchange component 3 is mainly used to increase the temperature of related components (such as the condenser 32) and the temperature of the clothes in the clothes processing drum 2, that is, the condenser 32 is quickly heated to heat the air in the heat exchange channel 4, and the heated air is used to heat the clothes in the clothes processing drum 2.

[0050] The second stage is a steady-state stage. In this stage, the heat pump heat exchange component 3 reaches the best working efficiency, the heat exchange efficiency of the condenser 32 and the evaporator 31 is kept in a substantially constant best state, the air flow flowing in the heat exchange channel 4 and the inner cavity of the laundry treatment tub 2 is kept within the best heating temperature range, and the heat exchange efficiency of the laundry treatment device is the best.

[0051] The third stage is the power reduction stage. In this stage, the air temperature in the inner cavity of the laundry treatment tub 2 will further increase, the moisture on the clothes in the laundry treatment tub 2 will become less, and it will become more difficult to evaporate the moisture from the clothes, and the heat exchange efficiency of the heat pump heat exchange component 3 will decrease accordingly.

[0052] In the steady-state stage, due to the high temperature in the heat exchange channel 4, in order to ensure the heat exchange efficiency of the evaporator 31 and the condenser 32, the compressor 33 will overheat due to being in a high temperature and high pressure operating state, resulting in its own temperature being too high, and these excess heat will be transferred to the heat exchange channel 4 through the evaporator 31 and the condenser 32, so that the air flow in the heat exchange channel 4 will increase in temperature, causing the inner cavity of the clothing processing drum 2 to overheat, and the clothing processing equipment will be unable to maintain the optimal heat exchange efficiency, resulting in a decrease in heat exchange efficiency.

[0053] In a specific implementation, at least a portion of the heat exchanger 6 is arranged in the heat exchange channel 4, so that it can absorb part of the heat of the air in the heat exchange channel 4. The hot and humid air in the clothing processing drum 2 after heat exchange with the clothing can absorb heat through the heat exchanger 6 while exchanging heat with the heat pump heat exchange component 3, thereby realizing cooling of the air in the heat exchange channel 4. Therefore, to a certain extent, it avoids the compressor 33 from affecting the air temperature in the heat exchange channel 4 due to overheating, thereby avoiding affecting the optimal working efficiency of the clothing processing equipment in the steady state stage, thereby ensuring that the clothing processing equipment continues to maintain the steady state stage, or that the clothing processing equipment maintains the steady state stage for a longer time.

[0054] The clothing processing device provided in the present embodiment provides a heat exchange channel 4 between the housing 1 and the clothing processing drum 2 so that the heat exchange channel 4 is connected to the inner cavity of the clothing processing drum 2, and at least a portion of the heat pump heat exchange component 3 is provided in the heat exchange channel 4, so that the heat pump heat exchange component 3 can exchange heat with the air in the heat exchange channel 4 to achieve drying of the clothing in the inner cavity of the clothing processing drum 2. At the same time, a heat exchanger 6 is provided so that at least a portion of the heat exchanger 6 is located in the heat exchange channel 4, so that part of the heat of the air in the heat exchange channel 4 is absorbed by the heat exchanger 6. For example, when the clothing processing device is in a steady-state stage, the compressor 33 of the heat pump heat exchange component 3 will overheat, thereby causing There is excess heat in the heat exchange channel 4, and the excess heat will cause the cycle time of the clothing processing equipment to increase and the energy consumption to increase. Therefore, by arranging the heat exchanger 6, the heat exchanger 6 can absorb a certain degree of excess heat transferred by the compressor 33 at least in the steady state stage, that is, the heat in the heat exchange channel 4 is balanced by the heat exchanger 6, thereby avoiding to a certain extent the overheating of the clothing processing drum 2 caused by the excess heat transferred by the compressor 33, reducing the equipment cycle time and energy consumption, and achieving the air flow flowing in the heat exchange channel 4 and the inner cavity of the clothing processing drum 2 to be maintained within a preferred heating temperature range, thereby improving the heat exchange efficiency of the clothing processing equipment.

[0055] The clothes processing device provided in this embodiment can be a clothes dryer or a washer-dryer, etc. The clothes processing drum 2 of the clothes processing device can be a drum type or a pulsator type. In this embodiment, a drum type clothes dryer is used as an example for description.

[0056] Reference Figure 1As shown, in some embodiments, the evaporator 31 is located on the upstream side of the condenser 32, and the heat exchanger 6 is located on the upstream side of the evaporator 31. This arrangement enables the air flow flowing from the inner cavity of the laundry treatment tub 2 into the heat exchange channel 4 to first pass through the heat exchanger 6, so that a part of the heat in the air is pre-absorbed by the heat exchanger 6, so that when the air flow flows to the evaporator 31 again, the temperature can be further reduced, so that the evaporator 31 has a better cooling and condensing effect on the air in the heat exchange channel 4, and the energy consumption of the evaporator 31 can also be reduced to a certain extent.

[0057] For example, the heat exchanger 6 can be detachably installed in the housing 1, for example, the heat exchanger 6 is detachably connected to the housing 1 by screwing or clamping. In this case, a mounting port connected to the heat exchange channel 4 can be opened on the housing 1, and the heat exchanger 6 can be placed in the heat exchange channel 4 through the mounting port, or taken out of the housing 1 through the mounting port.

[0058] In some embodiments, the heat exchanger 6 may also be arranged between the evaporator 31 and the condenser 32. This arrangement enables the air flowing from the inner cavity of the laundry processing drum 2 into the heat exchange channel 4 to be cooled and condensed by the evaporator 31, and then further absorb heat by the heat exchanger 6, so that the air in the heat exchange channel 4 can be double cooled, which can achieve a better cooling and condensing effect, and further improve the heat exchange efficiency and drying efficiency of the laundry processing device.

[0059] Reference Figure 2 and Figure 3 As shown, in some embodiments, the heat exchanger 6 includes a heat absorbing body 61 and an air flow channel 6a connected to the heat exchange channel 4. The heat absorbing body 61 contacts and exchanges heat with the air flow channel 6a to absorb part of the heat of the air in the air flow channel 6a.

[0060] That is, the air in the heat exchange channel 4 can enter the heat exchanger 6 through the air flow channel 6a. Since the heat absorbing body 61 contacts and exchanges heat with the air flow channel 6a, the heat absorbing body 61 absorbs part of the heat of the air flowing into the air flow channel 6a from the heat exchange channel 4, which makes the heat exchange effect between the heat absorbing body 61 and the air better, thereby further improving the heat absorption effect of the heat exchanger 6. In addition, the setting of the air flow channel 6a can also guide the air flow, ensure the air flow velocity in the heat exchange channel 4, thereby further ensuring the heat exchange efficiency of the clothing processing device.

[0061] Among them, the heat absorption body 61 contacts and exchanges heat with the air flow channel 6a. Specifically, for example, the heat absorption body 61 can be in direct contact and heat exchange with the air flow channel 6a (for example, when there are multiple heat absorption bodies 61, an air flow channel 6a is defined between two adjacent heat absorption bodies 61, and the air in the air flow channel 6a is in direct contact and heat exchange with the heat absorption body 61), or the heat absorption body 61 can be in indirect contact and heat exchange with the air flow channel 6a (for example, the heat absorption body 61 contacts other structures with air flow channel 6a formed inside, so that the air in the air flow channel 6a can be in contact and heat exchange with the heat absorption body 61 through the structure).

[0062] In some embodiments, the heat absorption body 61 has a cooling medium channel 6b, which has an inlet and an outlet, which are respectively connected to the outside world. The inlet of the cooling medium channel 6b is used for the cooling medium to enter, and the cooling medium is used to exchange heat with the air entering the air flow channel 6a.

[0063] That is to say, by introducing the cooling medium into the cooling medium channel 6b, the cooling medium enters the cooling medium channel 6b from the inlet, and then exchanges heat with the air in the air flow channel 6a, absorbing the heat in the air, and the cooling medium after absorbing the heat of the air is then discharged to the outside from the above outlet, thereby achieving heat exchange, with a simple structure and good heat exchange effect. Through the above arrangement, the cooling medium with a lower temperature can be continuously flowed into the cooling medium channel 6b to a certain extent to exchange heat with the air in the air flow channel 6a, and a better heat absorption effect of the air in the air flow channel 6a can be achieved, that is, the heat absorption effect of the heat exchanger 6 is further improved, thereby further improving the heat exchange efficiency of the clothing processing device.

[0064] In other embodiments, the heat absorption body 61 may also absorb part of the heat of the air in the air flow channel 6a in other ways. For example, the interior of the heat absorption body 61 has a phase change material, and the phase change material can reduce the temperature of the heat absorption body 61 itself by undergoing a phase change, so as to cool the air in the air flow channel 6a, thereby achieving the effect of absorbing part of the heat of the air in the air flow channel 6a.

[0065] In some embodiments, the cooling medium is gas. Compared with cooling medium in other states, the cooling medium uses gas, which has a faster flow rate, so the heat exchange effect of the cooling medium is better, thereby further improving the heat absorption effect of the heat exchanger 6 and the heat exchange efficiency of the clothing processing device.

[0066] Reference Figure 2 As shown, in a specific implementation, the gas can be cold air outside the clothing processing device, and the inlet and outlet of the cooling medium channel 6b are both connected to the outside, so that the cold air from the outside can be introduced into the cooling medium channel 6b to achieve heat absorption of the air in the air flow channel 6a.

[0067] For details, please refer to Figure 2 As shown, illustratively, an air inlet 11 and an air outlet 12 connected to the outside can be opened on the surface of the box body 1, the inlet of the cooling medium channel 6b is connected to the air inlet 11, and the outlet of the cooling medium channel 6b is connected to the air outlet 12.

[0068] In some embodiments, there are at least two heat absorbing bodies 61, and at least two heat absorbing bodies 61 are arranged at intervals, and an air flow channel 6a is defined between two adjacent heat absorbing bodies 61. This arrangement enables the air flow in the air flow channel 6a to achieve contact heat exchange with the two adjacent heat absorbing bodies 61, that is, the heat exchange area between the air flow in the air flow channel 6a and the heat absorbing bodies 61 is increased, thereby further improving the heat exchange effect of the heat exchanger 6, and further improving the heat exchange efficiency of the clothing processing device.

[0069] See also Figure 3 As shown. Exemplarily, the heat exchanger 6 can be configured to include a plurality of hollow first shells and a plurality of hollow second shells 63. The first shell is a heat absorbing body 61, and a cooling medium channel 6b is formed inside the first shell, and an air flow channel 6a is formed inside the second shell 63. The first shell and the second shell 63 are stacked in an alternating manner, which not only defines the air flow channel 6a, but also ensures the structural stability of the cooling medium channel 6b.

[0070] Exemplarily, the shapes of the first shell and the second shell 63 can match each other, so that the overall structure of the heat exchanger 6 is regular, so that it can be more conveniently arranged inside the box 1, and is compatible with the shape of the evaporator 31, thereby improving the space utilization inside the box 1. Exemplarily, the first shell and the second shell 63 can be connected together by a connector, so that the heat exchanger 6 forms an integral structure, which is convenient for assembly and transportation.

[0071] In some embodiments, reference Figure 3 As shown, the inlet of the cooling medium channel 6b and the inlet of the air flow channel 6a can be arranged on different sides of the heat exchanger 6. This arrangement can prevent the hotter cooling medium at the outlet of the cooling medium channel 6b from interfering with the lower temperature cooling medium at the inlet and affecting the low temperature state of the cooling medium before entering the channel, thereby further ensuring the heat exchange effect of the heat absorbing body 61.

[0072] See also Figure 3As shown, exemplarily, the inlet of the cooling medium channel 6b and the air inlet of the air flow channel 6a can be arranged on two adjacent different sides of the heat exchanger 6. For example, when the heat exchanger 6 is a cubic structure, the inlet and outlet of the cooling medium channel 6b are opened on two opposite sides of the cubic structure, and the air inlet and air outlet of the air flow channel 6a are opened on the other two opposite sides of the cubic structure, thereby not only ensuring the contact heat exchange between the heat absorption body 61 and the air flow channel 6a, but also realizing that the inlet of the cooling medium channel 6b and the inlet of the air flow channel 6a are located on different sides of the heat exchanger 6.

[0073] In some embodiments, the cooling medium channel 6b is provided with heat exchange fins 62. The heat exchange fins 62 can increase the contact area between the cooling medium and the inside of the cooling medium channel 6b, thereby improving the heat absorption effect of the cooling medium on the air in the air flow channel 6a, further improving the heat exchange efficiency of the heat exchanger 6, and thus achieving an improvement in the heat exchange efficiency of the clothing processing device to a certain extent.

[0074] Reference Figure 4 As shown, for example, the extension direction of the heat exchange fins 62 can be set to be the same as the extension direction of the cooling medium channel 6b. This arrangement enables the cooling medium to exchange heat with the heat exchange fins 62 for a longer time during the flow of the cooling medium channel 6b, so that the cooling medium has a better heat absorption effect on the air in the air flow channel 6a, thereby further improving the heat absorption effect of the heat exchanger 6 and further improving the heat exchange efficiency of the clothing processing device.

[0075] In some embodiments, there are multiple heat exchange fins 62, and the multiple heat exchange fins 62 are arranged in the cooling medium channel 6b at intervals. This arrangement enables the cooling medium to exchange heat with as many heat exchange fins 62 as possible when flowing in the cooling medium channel 6b, thereby further improving the heat absorption effect of the heat exchanger 6.

[0076] Reference Figure 4 As shown, for example, a plurality of heat exchange fins 62 are arranged at intervals along the width direction of the cooling medium channel 6b, and each heat exchange fin 62 is arranged along the extension direction of the cooling medium channel 6b. Of course, in other embodiments, the heat dissipation fins may also be arranged in other forms, such as a plurality of heat exchange fins 62 arranged at intervals in front and back along the extension direction of the cooling medium channel 6b.

[0077] Exemplarily, the first shell 63 , the second shell 63 and the heat exchange fins 62 of the heat exchanger 6 can all be made of metal materials (such as aluminum, copper, etc.) to achieve a better heat exchange effect.

[0078] In some embodiments, a water collecting structure is further provided in the housing 1, and at least part of the water collecting structure is located below the heat exchanger 6 to at least collect condensed water generated on the heat exchanger 6. The water collecting structure can collect condensed water generated on the heat exchanger 6 after the air in the heat exchange channel 4 flows through the heat exchanger 6, so that the surface of the heat exchanger 6 is dry, thereby further ensuring the dryness of the air in the heat exchange channel 4, and at the same time, it can also prevent the condensed water from dripping or flowing to other components in the housing 1, causing the components to be damaged by water, and at the same time improve safety.

[0079] Exemplarily, the water collecting structure may be a water collecting tank, which may be in communication with the outside, so that the condensed water can be discharged to the outside of the clothing processing device in a timely manner.

[0080] In some embodiments, a heat dissipation fan 7 is further provided in the housing 1, and the air outlet side of the heat dissipation fan 7 faces the cooling medium channel 6b. In this way, the cooling air flow rate in the cooling medium channel 6b can be accelerated by the heat dissipation fan 7, thereby accelerating the heat exchange between the cooling air and the heat absorbing body 61, so that part of the heat of the air in the air flow channel 6a absorbed by the heat absorbing body 61 can be transferred to the outside through the cooling air more quickly, so that the heat exchanger 6 can achieve faster heat absorption and cooling, thereby further improving the heat absorption efficiency of the heat exchanger 6, and further improving the heat exchange efficiency of the heat pump heat exchange component 3 and the clothing processing device.

[0081] See also Figure 5 As shown, in one achievable manner, the heat dissipation fan 7 can be arranged at the place where the entrance of the cooling medium channel 6b is connected to the outside, that is, between the air inlet 11 of the box body 1 and the entrance of the cooling medium channel 6b. The air inlet side of the heat dissipation fan 7 is directed toward the air inlet 11 of the box body 1, and the air outlet side is directed toward the entrance of the cooling medium channel 6b.

[0082] Figure 2 An example of a cooling air flow path is specifically shown in FIG. 1. When the heat dissipation fan 7 is turned on, the external cooling air is introduced into the cooling medium channel 6b through the inlet of the cooling medium channel 6b, so that the external cooling air absorbs the heat transferred to the heat absorbing body 61 by the air in the air flow channel 6a, and the cooling air after absorbing the heat is then discharged to the outside through the outlet of the cooling medium channel 6b.

[0083] In some embodiments, the clothing processing device further includes a temperature sensor 8 and a controller. The heat dissipation fan 7 and the temperature sensor 8 are electrically connected to the controller respectively, the temperature sensor 8 is used to detect the temperature in the heat exchange channel 4, and the controller is used to control the working state of the heat dissipation fan 7 according to the temperature detected by the temperature sensor 8. In this way, the state of the heat dissipation fan 7 can be changed according to the specific state in the clothing processing device, which is flexible and energy-saving.

[0084] The working state here can be, for example, the opening, closing, power increase, power decrease, speed increase, speed decrease, etc. of the heat dissipation fan 7. The control mode of the controller for the heat dissipation fan 7 can be selected according to the needs of the operator.

[0085] This arrangement can, for example, enable the heat pump heat exchange component 3 to be not in a steady-state stage (for example, in a preheating stage, when the temperature detected by the temperature sensor 8 has not reached a preset temperature), and the heat exchanger 6 does not need to absorb heat from the air in the heat exchange channel 4, so that the cooling fan 7 can be turned off or operated at low power, so that the cooling medium channel 6b on the heat exchanger 6 can maintain a natural convection state at this time, thereby further saving the energy consumption of the clothing processing equipment and improving the working efficiency of the clothing processing equipment.

[0086] For example, when the temperature detected by the temperature sensor 8 reaches a preset temperature (for example, in a steady state), the controller controls the cooling fan 7 to turn on, or controls the speed or power of the cooling fan 7 to increase, so that the cooling medium, that is, air, can enter the cooling medium channel 6b more, exchange heat with the hot air in the air flow channel 6a, and absorb part of the heat of the air in the air flow channel 6a, thereby preventing overheating.

[0087] Among them, the preset temperature can be set specifically according to actual conditions.

[0088] Specifically, the speed of the cooling fan 7 can be controlled by the controller, that is, by controlling the power of the cooling fan 7, so that the heat absorbed by the heat exchanger 6 to the air in the heat exchange channel 4 is the same as the heat transferred to the heat exchange channel 4 by the compressor 33, so that the heat inside the entire clothing processing device is maintained in a balanced state, thereby further ensuring that the heat pump heat exchange component 3 can maintain operation at the best working efficiency.

[0089] In specific implementation, the temperature sensor 8 can detect and transmit the actual temperature value in the heat exchange channel 4 to the controller in real time. For example, when the controller recognizes that the actual temperature value reaches the preset temperature, the controller outputs a control signal to the heat dissipation fan 7 to operate the heat dissipation fan 7, and the heat exchange efficiency of the heat exchanger 6 is further improved. When the controller recognizes that the actual temperature value drops below the preset temperature, the controller outputs a stop signal to the heat dissipation fan 7, and the heat dissipation fan 7 stops running.

[0090] Reference Figure 1 and Figure 5 As shown, in some embodiments, a sealing structure 9 is further provided in the housing 1 , and the sealing structure 9 is used to seal at least the connection between the laundry processing tub 2 and the housing 1 .

[0091] For details, please refer to Figure 5As shown, for example, when the laundry treatment drum 2 is disposed inside the housing 1, it is usually necessary to drive the laundry treatment drum 2 to be connected with the driving motor 19 disposed inside the housing 1, so that the driving motor 19 drives the laundry treatment drum 2 to rotate relative to the housing 1, and at the same time, the front side and the rear side of the laundry treatment drum 2 are respectively connected to the housing 1 to ensure that the laundry treatment drum 2 is installed and fixed while being able to rotate. In addition, a front air duct 15 that connects the air outlet 12 located on the front side of the laundry treatment drum 2 with the heat exchange channel 4 can be disposed inside the front panel 13 of the housing 1, and a rear air duct 16 that connects the air inlet 11 on the rear side of the laundry treatment drum 2 can be disposed inside the rear panel 14 of the housing 1.

[0092] Since the clothing processing drum 2 needs to rotate relative to the housing 1 during operation, there will be a structural gap 17 at the connection between the clothing processing drum 2 and the front panel 13 and the rear panel 14 of the housing 1. The structural gap 17 will cause the heat in the clothing processing drum 2 to leak from the connection, resulting in a slowdown in the temperature increase in the drum, thereby affecting the heat exchange efficiency of the entire clothing processing equipment.

[0093] The connection between the clothing processing drum 2 and the front panel 13 and the rear panel 14 of the housing 1 is sealed by the sealing structure 9, ensuring that the air in the inner cavity of the clothing processing drum 2 will not leak to the outside from the connection, thereby avoiding heat loss, thereby shortening the preheating time of the clothing processing device, and enabling the clothing processing device to enter the steady-state stage more quickly, thereby further improving the heat exchange efficiency of the clothing processing device and reducing the operating time and energy consumption.

[0094] Furthermore, by sealing the connection between the clothing processing drum 2 and the front panel 13 and the rear panel 14 of the housing 1 through the sealing structure 9, the sealing member originally provided at the connection between the clothing processing drum 2 and the housing 1 can be eliminated, thereby further avoiding power loss caused by friction between the clothing processing drum 2 and the sealing member during rotation, reducing motor consumption, and improving the working efficiency of the clothing processing equipment.

[0095] That is to say, by setting the sealing structure 9, the heat leakage in the clothing processing drum 2 is reduced to a certain extent, the heat in the clothing processing drum 2 is ensured, and the equipment can enter the steady-state stage as soon as possible; at the same time, by setting the heat exchanger 6, at least a part of the heat exchanger 6 is set in the heat exchange channel 4. When the clothing processing equipment is in the steady-state stage, the heat exchanger 6 can absorb the excess heat generated in the heat exchange channel 4 due to the overheating of the compressor 33, so that the heat in the heat exchange channel 4 reaches a balance, so that the clothing processing equipment is in a better working efficiency in the steady-state stage, so that the clothing processing equipment continues to maintain the steady-state stage, or the clothing processing equipment maintains the steady-state stage for a longer time, thereby reducing the equipment cycle time and energy consumption, and improving the heat exchange efficiency.

[0096] See also Figure 5 As shown, the sealing structure 9 is exemplarily a sealing barrel sleeved on the periphery of the clothing treatment tub 2. The sealing structure 9 uses a sealing barrel, which can better match the shape of the clothing treatment tub 2, so as to achieve sealing of the connection between the clothing treatment tub 2 and the housing 1 in all directions around the clothing treatment tub 2, so that the sealing effect is better, thereby further improving the heat exchange efficiency of the clothing treatment device.

[0097] The sealed barrel has an opening at a position corresponding to the clothing inlet 18 of the clothing processing barrel 2, and the opening is sealed with the edge of the clothing inlet 18. The sealing barrel is provided with an opening that avoids the position of the clothing inlet 18, so that the user can normally place clothing into the inner cavity of the clothing processing barrel 2 through the clothing inlet 18. In addition, the sealing of the opening of the sealed barrel with the edge of the clothing inlet 18 can further ensure the sealing effect of the sealed barrel.

[0098] See also Figure 5 As shown, for example, when the sealed barrel is installed in the box body 1, the sealed barrel and the clothes treatment barrel 2 can be coaxially arranged, and the front side of the sealed barrel is connected to the front panel 13 of the box body 1, and the rear side is connected to the rear panel 14 of the box body 1, so as to surround the clothes treatment barrel 2 and the connection between the clothes treatment barrel 2 and the box body 1 in the circumferential direction to further ensure the sealing effect. In addition, the sealed barrel and the box body 1 can be sealed and connected by a sealing member to further ensure the sealing effect.

[0099] In other embodiments, the sealing structure 9 may also adopt other structural settings to achieve sealing of the connection between the clothing processing drum 2 and the housing 1 .

[0100] See also Figure 6 As shown, Figure 6 The graph shows the relationship between the cycle time of the clothing treatment device and the air temperature value in the heat exchange channel. Curve A is a schematic curve showing the change of the air temperature in the heat exchange channel of the clothing treatment device over time during the device cycle when the heat exchanger 6 and the sealing structure 9 are not provided. Curve B is a schematic curve showing the change of the air temperature in the heat exchange channel 4 of the clothing treatment device over time during the device cycle after the heat exchanger 6 and the sealing structure 9 are provided in the heat exchange channel 4.

[0101] Reference Figure 6As shown in the curve A in , when the heat exchanger 6 and the sealing structure 9 are not provided, during the steady-state stage of the clothing processing device, the compressor 33 will overheat, resulting in excess heat generated in the heat exchange channel 4, and the inside of the clothing processing drum 2 will overheat. When the temperature of the compressor 33 itself is too high, it needs to be closed for self-protection, and the heat exchange efficiency of the heat pump heat exchange component 3 for the air in the heat exchange channel 4 will then decrease, and the air temperature in the heat exchange channel will correspondingly decrease. At this time, the clothing processing device does not have the optimal heating temperature in the steady-state stage. When the temperature of the compressor 33 drops to the normal operating temperature, the compressor 33 needs to be restarted, and the heat pump heat exchange component 3 continues to heat the air in the heat exchange channel 4 and gradually reaches the optimal heating temperature in the steady-state stage, and then it will be closed again when the compressor 33 is overheated, and then it will be turned on again for the next time, and it will operate in this cycle. In other words, due to the overheating problem of the compressor 33 in the steady-state stage, the temperature of the clothing processing device will continue to fluctuate during the cycle, affecting the maintenance of the steady-state stage.

[0102] Reference Figure 6 As shown in the curve B in FIG. 4 , by arranging the heat exchanger 6 and the sealing structure 9 in the heat exchange channel 4, the excessive heat generated in the heat exchange channel 4 due to the overheating of the compressor 33 can be absorbed by the heat exchanger 6, so that the heat in the heat exchange channel 4 reaches a balance, so that the clothing processing device is in a better working efficiency in the steady state stage, and the clothing processing device can continue to maintain the steady state stage or maintain the steady state stage for a longer time. At the same time, the sealing structure 9 reduces the heat leakage in the clothing processing drum 2 to a certain extent, ensures the heat in the clothing processing drum 2, enables the device to enter the steady state stage as soon as possible, and further plays the effect of extending the time of the steady state stage, thereby reducing the equipment cycle time and energy consumption, and improving the heat exchange efficiency.
