Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of clothing treatment, and more specifically, to an air supply component and a clothing treatment device. Background Art

[0002] Heat pump dryers have greatly improved people's quality of life, enabling the effect of wearing clothes immediately after drying, and having energy-saving characteristics at the same time. In related technologies, the filter guide rail of the heat pump system extends into the air duct. Due to the unreasonable design of the filter structure, the air resistance will increase, the air volume will be weakened, the heat exchange effect will be affected, and the clothing drying effect will be poor. Summary of the Invention

[0003] Embodiments of the present invention aim to solve at least one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of embodiments of the present invention provides an air supply component.

[0005] A second aspect of embodiments of the present invention provides a clothing treatment device.

[0006] In view of this, according to a first aspect of embodiments of the present invention, an air supply component is provided, including an air duct and a filter guide rail. The air duct includes an air inlet and an air outlet; at least a part of the filter guide rail extends into the air duct, the filter guide rail is located between the air inlet and the air outlet, and the filter guide rail includes a bending portion, and the bending portion is located in the air duct.

[0007] The air supply component provided by the embodiments of the present invention can be used in a clothing treatment device. The air duct can be connected to the barrel assembly of the clothing treatment device to circulate the air in the barrel assembly to achieve clothing drying. The filter guide rail is located between the air inlet and the air outlet of the air duct, so that the inserted filter can filter sundries such as lint mixed in the air flow entering the air duct through the air inlet, reducing the risk of sundries adhering to the surface of the heat exchanger in the air duct. By constructing a bending portion in the part of the filter guide rail extending into the air duct, the inserted filter can be deformed accordingly and be in a bent shape. Since under the condition of the same air duct size, the effective length of a curve is greater than that of a straight line, after such a design, the filter can intercept more lint, and the same amount of lint is distributed over a larger area, resulting in smaller air resistance and smaller air volume loss, which helps to improve the heat exchange efficiency between the air flow and the downstream heat exchanger and improve the clothing drying effect. Through experiments, compared with the straight filter design scheme, under the same conditions, the air volume of the air supply component provided by the embodiments of the present invention can be increased by about 20%.

[0008] Specifically, the air supply assembly further includes an air supply housing, and the air duct and the filter guide are both arranged inside the air supply housing. The air supply housing includes a detachable base and a cover body. Filter guides are provided on both the base and the cover body, which are respectively denoted as the cover body guide and the base guide to stably guide the movement of the filter. The air outlet is opened on the base.

[0009] Specifically, one end of the filter guide extending out of the air duct can be connected to the housing of the laundry treatment device, for example, connected to the control panel of the laundry treatment device, so as to insert or extract the filter through the corresponding position. Specifically, taking the case where one end of the filter guide extending out of the air duct is connected to the control panel as an example, the control panel is provided with an insertion port for the filter to be inserted. When the filter is inserted into the air duct and assembled in place, one end of the filter extending out of the air duct is embedded in the insertion port and adapted to the insertion port, making the appearance beautiful. A one-key ejection button can be provided on the end face of the filter. When the one-key ejection button is pressed, the filter can pop out a part from the housing, and the user can hold this part to extract the filter.

[0010] In addition, the air supply assembly provided according to the above technical solution of the present invention further has the following additional technical features:

[0011] In a possible design, the bending portion is arranged corresponding to the air inlet.

[0012] In this design, the air volume in the area of the air duct corresponding to the air inlet is the most concentrated, and the carried lint is also the most. By specifically arranging the bending portion in the area corresponding to the air inlet, on the one hand, the effective filtering area of the filter in this part of the area can be concentratedly increased to intercept more lint, and at the same time, the amount of lint distributed per unit area can be reduced, making the wind resistance smaller and the air volume loss smaller, which helps to improve the heat exchange efficiency between the air flow and the heat exchanger downstream and improve the laundry drying effect. On the other hand, in the position far from the air inlet, the bending portion does not need to be arranged, and the filter guide can extend approximately in a straight line, which can simplify the structure of the filter guide, reduce the processing difficulty, reduce the material consumption, and help to reduce the production cost. At the same time, the more bending areas of the filter guide, the greater the bending degree of the filter when inserting the filter, and the corresponding insertion difficulty will also increase. By reducing the bending area, the resistance when inserting the filter can be reduced, which is convenient for the user to operate, and the repeated deformation degree of the filter can be reduced, reducing the risk of fatigue failure of the filter and helping to extend the service life of the filter.

[0013] In a possible design, the bending portion protrudes towards the air inlet.

[0014] In this design, it is specifically defined that the protruding direction of the bent portion is the direction where the air inlet is located. Since the filter element is located between the air inlet and the air outlet, the space inside the air duct can thus be divided into an upstream space and a downstream space. The upstream space is connected to the air inlet, and the downstream space is connected to the air outlet. By making the bent portion protrude towards the upstream air inlet, the size of the downstream space can be relatively increased, so that the lint is distributed in the smaller upstream space, improving the heat exchange effect. In addition, if the bent portion protrudes towards the air outlet, then in order to avoid interference between the filter element and the downstream heat exchanger, the end of the filter element guide rail extending into the air duct needs to be moved in the direction away from the heat exchanger, resulting in an increase in the air inlet opening corresponding to the heat exchanger, which may affect the original air flow direction. Making the bent portion protrude towards the air inlet does not have this problem, and can reduce the impact on the original air flow direction, helping to ensure reliable heat exchange of the heat exchanger.

[0015] In a possible design, the intersection point of the center line of the air inlet and the bent portion is denoted as the reference point, and the included angle between the tangent plane of the bent portion at the reference point and the center line of the air inlet is greater than or equal to 80° and less than or equal to 100°.

[0016] In this design, the direction of the center line of the air inlet is the air inlet direction, and the intersection point of the center line of the air inlet and the bent portion is the main action point of the incoming air flow and the inserted filter element, and this point is denoted as the reference point. By limiting the value range of the included angle between the tangent plane of the bent portion at the reference point and the center of the air inlet to be between 80° and 100°, for example, 85°, 90°, 95°, that is, the air inlet direction can be made approximately perpendicular to the tangent plane of the bent portion at the reference point, so that the air inlet direction is approximately perpendicular to the filter element, achieving approximately perpendicular air inlet. On the one hand, this can reduce the resistance of the air, thus effectively increasing the air volume, improving the heat exchange efficiency, and improving the clothes drying effect. On the other hand, at this time, the filter element can better adsorb lint, making the lint on the filter element evenly distributed, helping to prevent excessive stacking of lint in a local area, so that the air volume can also be evenly distributed on the surface of the filter element, making the air volume entering the downstream heat exchanger uniform, and helping to ensure the heat exchange performance of the system.

[0017] In a possible design, the equivalent diameter d of the air inlet and the curvature radius r of any point of the bent portion satisfy 0.5d ≤ r ≤ 1.25d.

[0018] In this design, the equivalent diameter d of the air inlet is the diameter of a circular pipe (hereinafter referred to as the reference circular pipe for convenience of description) having the same hydraulic radius as the air inlet, which can reflect the size of the air inlet. By taking the equivalent diameter d of the air inlet as a reference, the value range of the curvature radius r of the bending portion is limited to 0.5d to 1.25d, that is, greater than or equal to the radius of the reference circular pipe and less than or equal to 2.5 times the radius of the reference circular pipe, so that the filter element at the corresponding part has an appropriate degree of bending. Specifically, the smaller the curvature radius of the bending portion, the greater the effective length of the filter element and the more lint that can be intercepted. The upper limit value can ensure that the curvature radius of the bending portion is small enough to meet the requirement of intercepting lint structurally, thereby controlling the air resistance and reducing the air volume loss. However, at the same time, the smaller the curvature radius of the bending portion, the greater the degree of bending, the greater the resistance when inserting the filter element, and the greater the loss of the filter element. The lower limit value can control the degree of bending within a reasonable range to ensure that the filter element can be smoothly inserted into the air duct through the filter element guide rail, and can reduce the repeated deformation degree of the filter element, reduce the risk of fatigue failure of the filter element, and help to extend the service life of the filter element.

[0019] In a possible design, the air supply assembly further includes a baffle and a first heat exchanger. The baffle extends from the inner wall surface of the air duct towards the inside of the air duct. The filter element guide rail extends into the air duct and towards the baffle until it contacts the baffle. The first heat exchanger includes a heat exchange body and a connecting pipe. The heat exchange body is located between the filter element guide rail and the air outlet. The connecting pipe is connected to the end of the heat exchange body facing the baffle, and the connecting pipe is located on the side of the baffle facing the air outlet.

[0020] In this design, since the filter element guide rail has a bent portion, after the filter element is inserted into the air duct, it will bend accordingly and deflect, resulting in only line contact between the filter element and the inner wall surface of the air duct, making it difficult to achieve surface contact. When the filter element is blown by the wind, there may be a gap between the filter element and the air duct, causing the air flow to pass through the gap, which not only affects the filtering effect but also causes the air volume to concentrate at the gap, further increasing the gap and forming a vicious cycle. By setting a baffle on the inner wall surface of the air duct and extending the filter element guide rail extending into the air duct to contact the baffle, the contact area between the filter element and the baffle can be increased, the morphological stability of the filter element can be enhanced, the risk of forming a gap between the filter element and the baffle can be reduced, and the filtering effect is ensured. At this time, the baffle and the filter element guide rail can jointly divide the space in the air duct into the aforementioned upstream space and downstream space. At the same time, the baffle can be used to block the air flow, so that the air flow entering the air duct can only enter the downstream space through the filter element inserted into the filter element guide rail, facilitating the reasonable planning of the air flow. The air supply assembly further includes a first heat exchanger disposed in the air duct. The first heat exchanger is located in the downstream space and includes a heat exchange main body that plays a major heat exchange role, and a connecting pipe located at the end of the heat exchange main body facing the baffle. The connecting pipe is specifically used to connect the heat exchange pipes in the heat exchange main body. By placing the connecting pipe on the downstream side of the baffle, the baffle can be used to shield the connecting pipe, so as to reduce the air volume blown to the connecting pipe, make the air volume more concentrated to pass through the heat exchange main body, help reduce the air volume loss, improve the heat exchange efficiency between the air flow and the first heat exchanger, and improve the clothing drying effect.

[0021] It can be understood that a connecting pipe can also be provided at the end of the first heat exchanger away from the baffle, and this part of the connecting pipe can extend outside the air duct.

[0022] In a possible design, the end of the heat exchange main body facing the baffle contacts the baffle.

[0023] In this design, for the end of the heat exchange main body facing the baffle, by further making this end contact the baffle, a closed structure can be formed by the baffle and the heat exchange main body to prevent air from leaking to the connecting pipe, which helps to fully reduce the air volume loss, improve the heat exchange efficiency between the air flow and the first heat exchanger, and improve the clothing drying effect. It can be understood that at this time, the air cannot reach the second wall of the air duct described below.

[0024] In a possible design, the air supply assembly further includes: a second heat exchanger, located between the first heat exchanger and the air outlet.

[0025] In this design, the air supply component further includes a second heat exchanger located downstream of the first heat exchanger, so that the air flow entering the air duct passes through the first heat exchanger and the second heat exchanger in sequence to achieve the treatment of the air flow. Specifically, the first heat exchanger is an evaporator, and the second heat exchanger is a condenser. Both the evaporator and the condenser have heat exchange tubes through which the refrigerant passes. When the air flow passes over the surface of the heat exchange tubes, heat can be exchanged with the refrigerant inside the tubes. The evaporator is located upstream of the condenser. The wet and cold air entering the air duct from the barrel assembly first contacts the evaporator. The refrigerant in the evaporator evaporates and absorbs heat, taking away the heat of the wet and cold air, causing the water vapor in the wet and cold air to cool and condense into a liquid state, and then being discharged, which can reduce the humidity of the wet and cold air and achieve dehumidification. The dehumidified dry and cold air then contacts the condenser downstream. The refrigerant in the condenser condenses and releases heat, transferring heat to the dry and cold air, causing the dry and cold air to warm up, obtaining warm and dry air. These warm and dry air return to the barrel assembly, which can promote the evaporation of moisture on the clothes, accelerate the drying of the clothes, and at the same time increase the air humidity in the barrel assembly. By repeating this cycle, the drying of the clothes can be achieved.

[0026] It can be understood that when only the first heat exchanger is provided in the air duct, the first heat exchanger can be an evaporator to achieve the dehumidification function, or a condenser to achieve the heating and drying function. These are all implementation manners of the present invention and fall within the protection scope of the present invention.

[0027] In a possible design, the air duct includes a rectangular channel and an inlet channel. The rectangular channel includes a first wall and a second wall connected to each other. The first wall is provided with an air outlet; the inlet channel is communicated with the second wall, and the inlet channel is inclined in a direction away from the first wall. One end of the inlet channel away from the rectangular channel forms an air inlet.

[0028] In this design, in terms of shape, by configuring the air duct as a connected rectangular channel and an inclined inlet channel, specifically making the inlet channel inclined in a direction away from the first wall from the end connected to the rectangular channel to the end away from the rectangular channel, the air flow entering the rectangular channel can flow obliquely towards the direction where the first wall is located. In other words, the rectangular channel can have an inclined air inlet towards the air outlet, forming a gradually expanding channel, which helps to increase the air flow space and can cooperate with the filter guide to facilitate the setting of the bending part, and helps to increase the effective filtering area of the filter.

[0029] In a possible design, the included angle between the center line of the air inlet and the first wall of the air duct is greater than or equal to 105° and less than or equal to 150°.

[0030] In this design, the extending direction of the center line of the air inlet is the same as that of the center line of the inlet channel. By defining the range of the included angle between the center line of the air inlet and the first wall of the air duct, the inclination degree of the inlet channel can be defined. By limiting the range of the included angle between 105° and 150°, it can not only ensure the formation of a gradually expanding channel, but also enable the air flow to smoothly pass through the filter element and blow to the heat exchanger, which helps to reduce the air volume loss, improve the heat exchange efficiency between the air flow and the downstream heat exchanger, and improve the clothes drying effect.

[0031] In a possible design, the rectangular channel further includes a third wall and a fourth wall connected to each other, and the third wall is arranged opposite to the first wall; the rectangular channel further includes a transition wall connected between the third wall and the fourth wall.

[0032] In this design, for the third wall and the fourth wall of the rectangular channel facing the air inlet, by connecting a transition wall between the two, the air flow can smoothly transition at the transition wall, reducing the generation of vortices, which helps to reduce the air volume loss, improve the heat exchange efficiency between the air flow and the downstream heat exchanger, and improve the clothes drying effect.

[0033] Specifically, the filter element guide rail passes through the transition wall, that is, it extends into the air duct through the transition wall. The aforementioned baffle is connected to the second wall, and the two ends of the heat exchanger face the second wall and the fourth wall respectively.

[0034] Specifically, the filter element is arranged between the third wall and the fourth wall, and the filter element extends through the transition wall to the baffle. The baffle is connected to the second wall and blocks the connecting pipe at the end of the first heat exchanger facing the baffle. At the same time, the connecting pipe at the end of the first heat exchanger away from the baffle can extend outside the fourth wall. That is to say, the shape formed by the filter element and the transition wall is connected to the fourth wall at one end and extends to the baffle at the other end, and the heat exchange body of the first heat exchanger is located between the baffle and the fourth wall. Therefore, during operation, the air passing through the filter element will flow along the shape formed by the filter element and the transition wall, all pass through the heat exchange body of the first heat exchanger, and then all pass through the corresponding part of the downstream second heat exchanger, which can avoid the loss of air volume. It can be understood that to facilitate the installation of the first heat exchanger and the second heat exchanger and extend the first heat exchanger and the second heat exchanger outside the fourth wall, the corresponding part of the fourth wall corresponding to the first heat exchanger and the second heat exchanger can be removed, leaving only the part between the first heat exchanger and the second heat exchanger.

[0035] In a possible design, the radius of curvature of the transition wall is greater than or equal to 60 mm and less than or equal to 120 mm.

[0036] In this design, the larger the radius of curvature of the transition wall, the smoother the transition between the third wall and the fourth wall, but the smaller the space of the air duct. By defining the value range of the radius of curvature of the transition wall to be 60 mm to 120 mm, it is possible to ensure smooth transition, reduce the generation of vortices, reduce the air volume loss, and ensure sufficient air duct space for the air flow to pass through. The comprehensive balance of the two helps to achieve a reasonable air volume and optimize the clothing drying effect. It can be understood that to ensure smooth transition, the transition wall needs to be a curved wall. In particular, when at least part of the wall surface of the transition wall is an arc wall, the radius of curvature of this part of the arc wall is equal to its radius.

[0037] In some embodiments, the air supply assembly further includes: an air inlet pipe, which is communicated with the air inlet.

[0038] In this design, the air supply assembly further includes an air inlet pipe connected to the air inlet of the air duct. Specifically, the end of the air inlet pipe facing away from the air inlet is communicated with the barrel assembly of the clothing treatment device. By providing an air inlet pipe at the air inlet of the air supply housing, the air inlet pipe can be used to communicate with the barrel assembly of the clothing treatment device, so that the air supply assembly and the barrel assembly can be reliably assembled. In addition, by using the air inlet pipe, after determining the installation position of the air supply housing, it is convenient to use the air inlet pipe to connect the air duct and the barrel assembly, which helps to improve the flexibility of the installation position of the air duct. Specifically, at least part of the pipe section of the air inlet pipe is a corrugated pipe, which helps to improve the vibration resistance performance of the air supply assembly. Specifically, the equivalent diameter d of the air inlet is equal to the diameter of the air inlet pipe.

[0039] Specifically, when the air supply housing includes a base and a cover, the base and the air inlet pipe can be set as an integral structure, which helps to improve the reliability of their connection, improves the assembly convenience, reduces the risk of air leakage from the connection between the two, and thus reduces the risk of wet air eroding and damaging other electrical components in the housing, which helps to extend the service life of the product.

[0040] In a possible design, the air supply assembly further includes: a fan, and the inlet of the fan is communicated with the outlet.

[0041] In this design, the air supply component further includes a blower connected to the air outlet of the air duct. Specifically, the outlet of the blower is connected to the barrel assembly of the laundry treatment device. That is to say, the air duct is connected to the barrel assembly via the blower. The outlet of the blower is specifically connected to the gasket at the laundry inlet of the barrel assembly, which can reduce the structural damage to the barrel assembly. By providing the blower, power can be provided for the circulation of the air flow, and the air flow direction can be planned. In the case where the air supply component includes the aforementioned evaporator and condenser, the air flow can be guided to pass through the evaporator first and then through the condenser, ensuring that the temperature of the air returning to the barrel assembly is relatively high to ensure the laundry drying effect. By specifically arranging the blower at the air outlet, a negative pressure can be formed at the air outlet, and the air flow can be guided to flow from the air inlet to the air outlet by using the pressure difference, ensuring the stability and reliability of the air flow direction. Specifically, the blower includes a blower housing and an impeller located inside the blower housing, and also includes a motor for driving the impeller to rotate. The inlet and outlet of the blower are specifically the inlet and outlet of the blower housing.

[0042] According to the second aspect of the embodiments of the present invention, there is provided a laundry treatment device including the air supply component provided in any of the above technical solutions, and thus has all the beneficial technical effects of the air supply component, which will not be elaborated herein. Specifically, the laundry treatment device is a heat pump washing and drying integrated machine in the form of a drum washing machine.

[0043] In addition, the laundry treatment device provided according to the above technical solutions of the present invention further has the following additional technical features:

[0044] In a possible design, the laundry treatment device further includes: a control panel, and the control panel includes an insertion port, and the insertion port is connected to one end of the filter guide rail extending out of the air duct.

[0045] In this design, by providing an insertion port connected to the filter guide rail at the control panel of the laundry treatment device, the filter can be inserted or withdrawn through the insertion port, realizing the taking and placing of the filter from the front of the laundry treatment device. Compared with the design of taking and placing the filter from the top, the taking and placing operation can be facilitated, and there is no need for the top operation space of the laundry treatment device, so that the top space of the laundry treatment device can be used to place other items. Specifically, when the filter is inserted into the air duct and assembled in place, one end of the filter extending out of the air duct is embedded in the insertion port and is adapted to the insertion port, making the appearance beautiful. A one-key ejection button can be provided on the end face of the filter. When the one-key ejection button is pressed, the filter can pop out a part from the housing, and the user can hold this part to withdraw the filter.

[0046] In a possible design, the laundry treatment device further includes: a barrel assembly, forming a cavity, and both the air inlet and the air outlet of the air duct are connected to the barrel assembly.

[0047] In this design, by setting up the barrel assembly, the cavity of the barrel assembly can be used to accommodate the clothes to be processed. The barrel assembly is connected to both the air inlet and the air outlet of the air duct, enabling the cavity and the air duct to form a closed-loop flow path to continuously process the air in the barrel assembly and complete the drying of the clothes.

[0048] Specifically, the barrel assembly includes a stationary outer barrel and an inner barrel that can rotate relative to the outer barrel. The outer barrel is used for storing water, and the inner barrel is used for accommodating clothes. The inner barrel and the outer barrel are connected to allow the washing water to enter the inner barrel. The inner barrel rotates according to a certain pattern, enabling the clothes to come into full contact with the washing water to achieve the washing of the clothes. After the washing is completed, the inner barrel rotates, and part of the water on the clothes can be thrown out under the action of centrifugal force to achieve dehydration of the clothes.

[0049] Specifically, the clothes treatment device further includes a housing, a compressor, and a pipeline assembly. The housing forms the overall framework of the clothes treatment device and can accommodate other structures such as the barrel assembly. The compressor is connected to the evaporator and the condenser of the air supply assembly through the pipeline assembly, and can provide power for the circulation of the refrigerant to ensure the reliable operation of the evaporator and the condenser, guaranteeing the drying effect of the clothes treatment device. Separately arranging the relatively large compressor from the air supply assembly can reasonably utilize the space inside the housing for layout. By introducing a heat pump system into the clothes treatment device while maintaining the original overall height of the machine or only slightly increasing the overall height of the machine, a heat pump washing and drying integrated machine is formed, which helps to reduce the overall size of the clothes treatment device, reduce the space occupied by the clothes treatment device, and contribute to enhancing the market competitiveness of the product.

[0050] Specifically, the air supply assembly is arranged in the top space of the housing, and the compressor is arranged in the bottom space of the housing. For example, the compressor is connected to the bottom plate of the housing, so that the compressor and the air supply assembly are separately arranged, which helps to reduce the occupation of the top space of the housing and reduce the overall height of the clothes treatment device.

[0051] Further, the air inlet of the compressor is connected to the outlet of the evaporator, and the air outlet of the compressor is connected to the inlet of the condenser. The air supply assembly further includes a throttling device, such as a capillary tube, disposed between the outlet of the condenser and the inlet of the evaporator, forming a refrigerant circulation path of compressor → condenser → throttling device → evaporator → compressor, which constitutes a heat pump system. Specifically, the refrigerant is compressed into a high-temperature and high-pressure gaseous refrigerant in the compressor. The high-temperature and high-pressure gaseous refrigerant is discharged from the compressor through the air outlet of the compressor and then enters the condenser to condense and release heat. The high-temperature and high-pressure gaseous refrigerant gradually turns into a high-pressure liquid refrigerant. The high-pressure liquid refrigerant flows out of the condenser and enters the throttling device for throttling to reduce the temperature and pressure. The high-pressure liquid refrigerant turns into a low-temperature and low-pressure gas-liquid mixed refrigerant. Then, the low-temperature and low-pressure refrigerant flows out of the throttling device and enters the evaporator to absorb heat from the surrounding environment and continuously evaporate, turning into a low-pressure gaseous refrigerant. The low-pressure gaseous refrigerant flows out of the evaporator and then re-enters the compressor through the air inlet of the compressor for compression, and so on in a cycle.

[0052] Further, the laundry treatment device further includes a connecting member that is connected to both the housing and the air supply assembly. The connecting member is located on the side of the air supply assembly facing away from the tub assembly. By providing the connecting member connected to the air supply assembly, the air supply assembly can be carried and moved by holding the connecting member. Specifically, the connecting member can be connected to the air supply housing. At the same time, since the connecting member is specifically connected to the side of the air supply assembly facing away from the tub assembly, that is, facing outward, the connecting member can always be exposed within the visual range and operating range of the assembly personnel, and can also always be exposed within the operating range of the automated assembly equipment. That is, during the entire assembly process, the position of the air supply assembly can be adjusted through the connecting member, which is convenient for operation. In addition, the connecting member is also connected to the housing. After the position of the air supply assembly is adjusted, the connecting member can be directly fixedly connected to the housing, thereby realizing the fixed connection between the air supply assembly and the housing, and thus completing the assembly of the air supply assembly. In other words, by providing the connecting member, the handling and assembly of the air supply assembly can be directly completed by using the connecting member, which helps to greatly improve the assembly efficiency of the air supply assembly and the housing, and improve the production output of the laundry treatment device.

Detailed Description of the Invention

[0067] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0068] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0069] Refer to the following Figures 1 to 10 The air supply assembly 100 and the clothes treating apparatus provided according to some embodiments of the present invention are described.

[0070] like Figure 1 and Figure 2 As shown, an embodiment of the first aspect of the present invention provides an air supply assembly 100, comprising an air duct 120 and a filter guide rail 130. The air duct 120 comprises an air inlet 122 and an air outlet 124; at least a portion of the filter guide rail 130 extends into the air duct 120, the filter guide rail 130 is located between the air inlet 122 and the air outlet 124, and the filter guide rail 130 comprises a curved portion 132, which is located in the air duct 120.

[0071] The air supply assembly 100 provided in the embodiment of the present invention can be used in a clothes processing device, and the air duct 120 can be connected to the barrel assembly 200 of the clothes processing device to circulate the air in the barrel assembly 200 to achieve clothes drying. The filter element guide rail 130 is located between the air inlet 122 and the air outlet 124 of the air duct 120, so that the inserted filter element 140 can filter the fluff and other debris mixed in the air flow entering the air duct 120 through the air inlet 122, thereby reducing the risk of debris adhering to the heat exchanger surface in the air duct 120. By constructing a curved portion 132 at the portion of the filter element guide rail 130 extending into the air duct 120, the filter element 140 inserted therein can be deformed and curved. Since the effective length of the curve is greater than the straight length under the same air duct size, after such design, the filter 140 can intercept more hair debris, and the same amount of hair debris is distributed over a larger area, so that the wind resistance is smaller and the air volume loss is smaller, which helps to improve the heat exchange efficiency between the airflow and the downstream heat exchanger and improve the clothes drying effect. According to the test, compared with the straight filter design, under the same conditions, the air volume of the air supply assembly 100 provided by the embodiment of the present invention can be increased by about 20%.

[0072] Specifically, Figures 1 to 3As shown, the air supply assembly 100 further includes an air supply housing 110, and the air duct 120 and the filter guide 130 are both disposed within the air supply housing 110. The air supply housing 110 includes a detachable base 112 and a cover 114. Filter guides 130 are provided on both the base 112 and the cover 114, denoted as the cover guide 136 and the base guide 134 respectively, to stably guide the movement of the filter element 140. As Figure 2 shown, the air outlet 124 is formed on the base 112.

[0073] Specifically, one end of the filter guide 130 extending out of the air duct 120 can be connected to the housing 300 of the laundry treatment apparatus. For example, Figure 1 as shown, it is connected to the control panel 310 of the laundry treatment apparatus to insert or extract the filter element 140 through the corresponding position. Specifically, taking the case where one end of the filter guide 130 extending out of the air duct 120 is connected to the control panel 310 as an example, as Figure 4 and Figure 5 shown, the control panel 310 is provided with an insertion port 312 for inserting the filter element 140. When the filter element 140 is inserted into the air duct 120 and assembled in place, one end of the filter element 140 extending out of the air duct 120 is embedded in the insertion port 312 and is adapted to the insertion port 312, making the appearance aesthetically pleasing. A one-key ejection button 142 can be provided on the end face of the filter element 140. When the one-key ejection button 142 is pressed, the filter element 140 can be ejected from the housing 300 by a part, and the user can hold this part to extract the filter element 140.

[0074] As Figure 2 shown, in some embodiments, the bending portion 132 is disposed corresponding to the air inlet 122.

[0075] In this embodiment, the air volume in the air duct 120 is most concentrated in the area corresponding to the air inlet 122, and the most lint is carried. By specifically arranging the bending portion 132 in the area corresponding to the air inlet 122, on the one hand, the effective filtering area of the filter element 140 in this part of the area can be concentratedly increased to intercept more lint, and at the same time, the amount of lint distributed per unit area can be reduced, making the resistance of the air smaller and the air volume loss smaller, which helps to improve the heat exchange efficiency between the air flow and the downstream heat exchanger and improve the clothes drying effect. On the other hand, the bending portion 132 does not need to be arranged at a position far from the air inlet 122, and the filter element guide rail 130 can extend approximately in a straight line, which can simplify the structure of the filter element guide rail 130, reduce the processing difficulty, reduce the material consumption, and help to reduce the production cost. At the same time, the more bending areas of the filter element guide rail 130, the greater the bending degree of the filter element 140 when the filter element 140 is inserted, and the corresponding insertion difficulty will also increase. By reducing the bending area, the resistance when inserting the filter element 140 can be reduced, which is convenient for the user to operate, and the repeated deformation degree of the filter element 140 can be reduced, and the risk of fatigue failure of the filter element 140 can be reduced, which helps to extend the service life of the filter element 140.

[0076] As Figure 2 and Figure 3 shown, in some embodiments, the bending portion 132 protrudes towards the air inlet 122.

[0077] In this embodiment, the protruding direction of the bending portion 132 is specifically defined as the direction where the air inlet 122 is located. Since the filter element 140 is located between the air inlet 122 and the air outlet 124, the space in the air duct 120 can be divided into an upstream space and a downstream space. The upstream space communicates with the air inlet 122, and the downstream space communicates with the air outlet 124. By making the bending portion 132 protrude towards the upstream air inlet 122, the size of the downstream space can be relatively increased, so that the lint is distributed in the smaller upstream space, improving the heat exchange effect. In addition, if the bending portion 132 protrudes towards the air outlet 124, then in order to avoid interference between the filter element 140 and the downstream heat exchanger, the end of the filter element guide rail 130 extending into the air duct 120 needs to be moved in a direction away from the heat exchanger, resulting in an increase in the air inlet opening corresponding to the heat exchanger, which may affect the original air flow direction. Making the bending portion 132 protrude towards the air inlet 122 does not have this problem, and can reduce the influence on the original air flow direction, which helps to ensure the reliable heat exchange of the heat exchanger.

[0078] As Figure 7 shown, in some embodiments, the intersection point of the center line of the air inlet 122 and the bending portion 132 is denoted as the reference point, and the included angle α between the tangent plane of the bending portion 132 at the reference point and the center line of the air inlet 122 is greater than or equal to 80° and less than or equal to 100°.

[0079] In this embodiment, the centerline direction of the air inlet 122 is the air inlet direction, and the intersection point of the centerline of the air inlet 122 and the bent portion 132 is the main acting point of the incoming air flow and the inserted filter element 140, which is denoted as the reference point. By limiting the value range of the included angle α between the tangent plane of the bent portion 132 at the reference point and the center of the air inlet 122 to be between 80° and 100°, for example, 85°, 90°, 95°, that is, the air inlet direction can be made approximately perpendicular to the tangent plane of the bent portion 132 at the reference point, and the air inlet direction can be made approximately perpendicular to the filter element 140, realizing approximately perpendicular air inlet. On the one hand, this can reduce the resistance of the air, thereby effectively increasing the air volume, improving the heat exchange efficiency, and improving the clothing drying effect. On the other hand, at this time, the filter element 140 can better adsorb lint, so that the lint on the filter element 140 is evenly distributed, which helps to prevent excessive stacking of lint in a local area, so that the air volume can also be evenly distributed on the surface of the filter element 140, making the air volume entering the downstream heat exchanger uniform, and helping to ensure the heat exchange performance of the system.

[0080] In some embodiments, the equivalent diameter d of the air inlet 122 and the radius of curvature r of any point on the bent portion 132 satisfy 0.5d ≤ r ≤ 1.25d.

[0081] In this embodiment, the equivalent diameter d of the air inlet 122 is the diameter of a circular pipe having the same hydraulic radius as it (for the convenience of description, hereinafter referred to as the reference circular pipe), which can reflect the size of the air inlet 122. By referring to the equivalent diameter d of the air inlet 122, the value range of the radius of curvature r of the bent portion 132 is limited to 0.5d to 1.25d, that is, greater than or equal to the radius of the reference circular pipe and less than or equal to 2.5 times the reference circular pipe, which can make the corresponding filter element 140 have an appropriate degree of bending. Specifically, the smaller the radius of curvature of the bent portion 132, the greater the effective length of the filter element 140, and the more lint that can be intercepted. The upper limit value can ensure that the radius of curvature of the bent portion 132 is small enough to meet the requirement of intercepting lint from the structure, thereby controlling the air resistance and reducing the air volume loss. However, at the same time, the smaller the radius of curvature of the bent portion 132, the greater the degree of bending, the greater the resistance when inserting the filter element 140, and the greater the loss of the filter element 140. The lower limit value can control the degree of bending within a reasonable range to ensure that the filter element 140 can be smoothly inserted into the air duct 120 through the filter element guide rail 130, and can reduce the degree of repeated deformation of the filter element 140, reduce the risk of fatigue failure of the filter element 140, and help to extend the service life of the filter element 140.

[0082] Such as Figure 2 and Figure 7As shown, in some embodiments, the air supply assembly 100 further includes a baffle 150 and a first heat exchanger 160. The baffle 150 extends from the inner wall surface of the air duct 120 towards the interior of the air duct 120. The filter guide rail 130 extends into the air duct 120 and towards the baffle 150 until it contacts the baffle 150. The first heat exchanger 160 includes a heat exchange body 162 and a connecting pipe 164. The heat exchange body 162 is located between the filter guide rail 130 and the air outlet 124. The connecting pipe 164 is connected to the end of the heat exchange body 162 facing the baffle 150, and the connecting pipe 164 is located on the side of the baffle 150 facing the air outlet 124.

[0083] In this embodiment, since the filter guide rail 130 has a bending portion 132, after the filter element 140 is inserted into the air duct 120, it will bend accordingly and deflect, so that the filter element 140 can only have line contact with the inner wall surface of the air duct 120, and it is difficult to achieve surface contact. When the filter element 140 is blown by the wind, there may be a gap between the filter element 140 and the air duct 120, causing the air flow to pass through the gap, which not only affects the filtering effect, but also causes the air volume to concentrate at the gap, further causing the gap to increase, forming a vicious cycle. By providing a baffle 150 on the inner wall surface of the air duct 120 and extending the filter guide rail 130 extending into the air duct 120 to contact the baffle 150, the contact area between the filter element 140 and the baffle 150 can be increased, the morphological stability of the filter element 140 can be increased, and the risk of forming a gap between the filter element 140 and the baffle 150 can be reduced, ensuring the filtering effect. At this time, the baffle 150 and the filter guide rail 130 can jointly divide the space in the air duct 120 into the aforementioned upstream space and downstream space. At the same time, the baffle 150 can be used to block the air flow, so that the air flow entering the air duct 120 can only enter the downstream space through the filter element 140 inserted into the filter guide rail 130, which is convenient for reasonable planning of the air flow. The air supply assembly 100 further includes a first heat exchanger 160 provided in the air duct 120. The first heat exchanger 160 is located in the downstream space and includes a heat exchange body 162 that plays a main heat exchange role, and a connecting pipe 164 located at the end of the heat exchange body 162 facing the baffle 150. The connecting pipe 164 is specifically used to connect the heat exchange pipes in the heat exchange body 162. By making the connecting pipe 164 on the downstream side of the baffle 150, the baffle 150 can be used to block the connecting pipe 164 to reduce the air volume blown to the connecting pipe 164, so that the air volume passes more concentratedly through the heat exchange body 162, which helps to reduce the air volume loss, improve the heat exchange efficiency between the air flow and the first heat exchanger 160, and improve the clothing drying effect.

[0084] It can be understood that, as Figure 7 shown, a connecting pipe can also be provided at the end of the first heat exchanger 160 away from the baffle 150, and this part of the connecting pipe can extend outside the air duct 120.

[0085] As Figure 7As shown, in some embodiments, the end of the heat exchange body 162 facing the baffle 150 is in contact with the baffle 150.

[0086] In this embodiment, for the end of the heat exchange body 162 facing the baffle 150, by further bringing this end into contact with the baffle 150, a closed structure can be formed by the baffle 150 and the heat exchange body 162, avoiding air leakage to the connecting pipe 164, which helps to fully reduce the air volume loss, improve the heat exchange efficiency between the air flow and the first heat exchanger 160, and improve the clothing drying effect. It can be understood that at this time, the air cannot reach the second wall 1262 of the air duct 120 described below.

[0087] As Figure 7 shown, in some embodiments, the air supply assembly 100 further includes: a second heat exchanger 170, located between the first heat exchanger 160 and the air outlet 124.

[0088] In this embodiment, the air supply assembly 100 further includes a second heat exchanger 170 downstream of the first heat exchanger 160, so that the air flow entering the air duct 120 passes through the first heat exchanger 160 and the second heat exchanger 170 in sequence to realize the treatment of the air flow. Specifically, the first heat exchanger 160 is an evaporator, and the second heat exchanger 170 is a condenser. Both the evaporator and the condenser have heat exchange tubes for the refrigerant to pass through. When the air flow passes through the surface of the heat exchange tubes, it can exchange heat with the refrigerant in the heat exchange tubes. The evaporator is located upstream of the condenser. The wet and cold air entering the air duct 120 from the barrel assembly 200 first contacts the evaporator. The refrigerant in the evaporator evaporates and absorbs heat, taking away the heat of the wet and cold air, so that the water vapor in the wet and cold air cools and condenses into a liquid state, and then is discharged, which can reduce the humidity of the wet and cold air and realize dehumidification. The dehumidified dry and cold air then contacts the downstream condenser. The refrigerant in the condenser condenses and releases heat, transferring heat to the dry and cold air, so that the dry and cold air warms up to obtain warm and dry air. These warm and dry air returns to the barrel assembly 200 again, which can promote the evaporation of moisture on the clothes, accelerate the drying of the clothes, and at the same time increase the air humidity in the barrel assembly 200. In this way, the drying of the clothes can be realized by repeating the cycle.

[0089] It can be understood that when only the first heat exchanger 160 is provided in the air duct 120, the first heat exchanger 160 can be an evaporator to realize the dehumidification function, or a condenser to realize the heating and drying function. These are all implementation manners of the present invention and fall within the protection scope of the present invention.

[0090] In some embodiments, the air duct 120 includes a rectangular channel 126 and an inlet channel 128. The rectangular channel 126 includes a first wall 1261 and a second wall 1262 that are connected to each other. The first wall 1261 is provided with an air outlet 124; the inlet channel 128 communicates with the second wall 1262, and the inlet channel 128 is inclined in a direction away from the first wall 1261. One end of the inlet channel 128 away from the rectangular channel 126 forms an air inlet 122.

[0091] In this embodiment, in terms of shape, by configuring the air duct 120 as a connected rectangular channel 126 and an inclined inlet channel 128, specifically, the inlet channel 128 is inclined in a direction away from the first wall 1261 from the end connected to the rectangular channel 126 to the end away from the rectangular channel 126, so that the air flow entering the rectangular channel 126 can flow obliquely towards the direction where the first wall 1261 is located. In other words, the rectangular channel 126 can be inclined to intake air towards the air outlet 124, forming a gradually expanding channel, which helps to increase the air flow space and can cooperate with the filter guide 130 to facilitate the setting of the bending portion 132, and helps to increase the effective filtration area of the filter.

[0092] In some embodiments, the included angle between the center line of the air inlet 122 and the first wall 1261 of the air duct 120 is greater than or equal to 105° and less than or equal to 150°.

[0093] In this embodiment, the extending direction of the center line of the air inlet 122 is the same as the extending direction of the center line of the inlet channel 128. By limiting the value range of the included angle between the center line of the air inlet 122 and the first wall 1261 of the air duct 120, the inclination degree of the inlet channel 128 can be limited. As Figure 7 shown, for the convenience of marking, the complementary angle β of this included angle is marked. That is, the value range of the complementary angle β is 30° to 75°. By limiting the value range of this included angle between 105° and 150°, it can not only ensure the formation of a gradually expanding channel, but also enable the air flow to smoothly blow through the filter 140 to the heat exchanger, which helps to reduce the air volume loss, improve the heat exchange efficiency between the air flow and the downstream heat exchanger, and improve the clothing drying effect.

[0094] As Figure 7 shown, in some embodiments, the rectangular channel 126 further includes a third wall 1263 and a fourth wall 1264 that are connected to each other. The third wall 1263 is arranged opposite to the first wall 1261; the rectangular channel 126 further includes a transition wall 1265 connected between the third wall 1263 and the fourth wall 1264.

[0095] In this embodiment, for the third wall 1263 and the fourth wall 1264 of the rectangular channel 126 facing the air inlet 122, by connecting a transition wall 1265 between the two, the air flow can smoothly transition at the transition wall 1265, reducing the generation of vortices, helping to reduce the air volume loss, improving the heat exchange efficiency between the air flow and the heat exchanger downstream, and enhancing the clothing drying effect.

[0096] Specifically, as Figure 7 shown, the filter guide rail 130 passes through the transition wall 1265, that is, it extends into the air duct 120 through the transition wall 1265. The aforementioned baffle 150 is connected to the second wall 1262, and the two ends of the heat exchanger face the second wall 1262 and the fourth wall 1264 respectively.

[0097] Specifically, the filter 140 is arranged between the third wall 1263 and the fourth wall 1264, and the filter 140 extends through the transition wall 1265 to the baffle 150. The baffle 150 is connected to the second wall 1262 and blocks the connecting pipe 164 at the end of the first heat exchanger 160 facing the baffle 150. At the same time, the connecting pipe at the end of the first heat exchanger 160 away from the baffle 150 can extend outside the fourth wall 1264. That is to say, one end of the shape formed by the filter 140 and the transition wall 1265 is connected to the fourth wall 1264, and the other end extends to the baffle 150, while the heat exchange body 162 of the first heat exchanger 160 is located between the baffle 150 and the fourth wall 1264. Therefore, during the working process, the air passing through the filter 140 will flow along the shape formed by the filter 140 and the transition wall 1265, all passing through the heat exchange body 162 of the first heat exchanger 160, and then all passing through the corresponding part of the second heat exchanger 170 downstream, which can avoid the loss of air volume. It can be understood that to facilitate the installation of the first heat exchanger 160 and the second heat exchanger 170 and extend the first heat exchanger 160 and the second heat exchanger 170 outside the fourth wall 1264, the part of the fourth wall 1264 corresponding to the first heat exchanger 160 and the second heat exchanger 170 can be removed, leaving only the part between the first heat exchanger 160 and the second heat exchanger 170 as Figure 7 shown.

[0098] In some embodiments, the radius of curvature of the transition wall 1265 is greater than or equal to 60 mm and less than or equal to 120 mm.

[0099] In this embodiment, the larger the radius of curvature of the transition wall 1265, the smoother the transition between the third wall 1263 and the fourth wall 1264, but the smaller the space of the air duct 120 will be accordingly. By defining the value range of the radius of curvature of the transition wall 1265 to be from 60 mm to 120 mm, it is possible to ensure a smooth transition, reduce the generation of vortices, and reduce the air volume loss, and at the same time ensure sufficient space in the air duct 120 for the air flow to pass through. The comprehensive balance of the two helps to achieve a reasonable air volume and optimize the effect of drying clothes. It can be understood that, to ensure a smooth transition, the transition wall 1265 needs to be a curved wall. In particular, when at least part of the wall surface of the transition wall 1265 is an arc wall, the radius of curvature of this part of the arc wall is equal to its radius.

[0100] As Figure 1 and Figure 6 shown, in some embodiments, the air supply assembly 100 further includes: an air inlet pipe 180, which is connected to the air inlet 122.

[0101] In this embodiment, the air supply assembly 100 further includes an air inlet pipe 180 connected to the air inlet 122 of the air duct 120. Specifically, the end of the air inlet pipe 180 facing away from the air inlet 122 is connected to the barrel assembly 200 of the laundry treatment device. By providing the air inlet pipe 180 at the air inlet 122 of the air supply housing 110, the air inlet pipe 180 can be used to connect to the barrel assembly 200 of the laundry treatment device, so that the air supply assembly 100 and the barrel assembly 200 can be reliably assembled. In addition, by using the air inlet pipe 180, after determining the installation position of the air supply housing 110, it is convenient to connect the air duct 120 to the barrel assembly 200 using the air inlet pipe 180, which helps to improve the flexibility of the installation position of the air duct 120. Specifically, at least part of the pipe section of the air inlet pipe 180 is a corrugated pipe, which helps to improve the vibration resistance performance of the air supply assembly 100. Specifically, the equivalent diameter d of the air inlet 122 is equal to the diameter of the air inlet pipe 180.

[0102] Specifically, when the air supply housing 110 includes a base 112 and a cover 114, the base 112 and the air inlet pipe 180 can be set as an integral structure, which helps to improve the reliability of the connection between the two, improves the assembly convenience, and reduces the risk of air leakage from the connection between the two, thereby reducing the risk of wet air eroding and damaging other electrical components in the housing 300, and helps to extend the service life of the product.

[0103] As Figure 1 and Figure 6 shown, in some embodiments, the air supply assembly 100 further includes: a fan 190, and the inlet of the fan 190 is connected to the air outlet 124.

[0104] In this embodiment, the air supply assembly 100 further includes a fan 190 connected to the air outlet 124 of the air duct 120. Specifically, the outlet of the fan 190 is connected to the barrel assembly 200 of the laundry treating apparatus. That is to say, the air duct 120 is connected to the barrel assembly 200 via the fan 190. As Figure 9 shown, the outlet of the fan 190 is specifically connected to the gasket 220 at the laundry inlet 210 of the barrel assembly 200, which can reduce the structural damage to the barrel assembly 200. By providing the fan 190, power can be provided for the circulation of the air flow, and the air flow direction can be planned. When the air supply assembly 100 includes the aforementioned evaporator and condenser, the air flow can be guided to pass through the evaporator first and then through the condenser, ensuring that the temperature of the air returning to the barrel assembly 200 is relatively high to ensure the laundry drying effect. By specifically arranging the fan 190 at the air outlet 124, a negative pressure can be formed at the air outlet 124, and the air flow can be guided to flow from the air inlet 122 to the air outlet 124 by using the pressure difference, ensuring the stability and reliability of the air flow direction. Specifically, the fan 190 includes a fan housing and an impeller located inside the fan housing, and further includes a motor for driving the impeller to rotate. The inlet and outlet of the fan 190 are specifically the inlet and outlet of the fan housing.

[0105] As Figure 7 and Figure 8 shown, an embodiment of the second aspect of the present invention provides a laundry treating apparatus, including the air supply assembly 100 provided in any of the above embodiments, and thus has all the beneficial technical effects of the air supply assembly 100, which will not be elaborated herein. Specifically, the laundry treating apparatus is a heat pump washing and drying integrated machine in the form of a drum washing machine.

[0106] As Figure 5 shown, in some embodiments, the laundry treating apparatus further includes: a control panel 310, and the control panel 310 includes an insertion port 312, and the insertion port 312 is connected to one end of the filter guide 130 extending out of the air duct 120.

[0107] In this embodiment, by providing the insertion port 312 connected to the filter guide 130 at the control panel 310 of the laundry treating apparatus, the filter element 140 can be inserted or withdrawn through the insertion port 312, so as to realize taking and placing the filter element 140 from the front of the laundry treating apparatus. Compared with the design of taking and placing the filter element 140 from the top, the taking and placing operation can be facilitated, and there is no need for the top operation space of the laundry treating apparatus, so that other items can be placed in the top space of the laundry treating apparatus. Specifically, when the filter element 140 is inserted into the air duct 120 and assembled in place, as Figure 4 and Figure 5As shown, one end of the filter element 140 extending out of the air duct 120 is inserted into the insertion opening 312 and is adapted to the insertion opening 312, making the appearance beautiful. A one-key ejection button 142 can be provided on the end face of the filter element 140. When the one-key ejection button 142 is pressed, the filter element 140 can pop out a part from the housing 300, and the user can hold this part to pull out the filter element 140.

[0108] In some embodiments, the laundry treatment device further includes: a tub assembly 200 that forms a cavity, and both the air inlet 122 and the air outlet 124 of the air duct 120 are connected to the tub assembly 200.

[0109] In this embodiment, by providing the tub assembly 200, the cavity of the tub assembly 200 can be used to accommodate the laundry to be processed. The tub assembly 200 is connected to both the air inlet 122 and the air outlet 124 of the air duct 120, and a closed-loop flow path can be formed between the cavity and the air duct 120 to continuously process the air in the tub assembly 200 to complete the drying of the laundry.

[0110] Specifically, the tub assembly 200 includes a stationary outer tub and an inner tub that can rotate relative to the outer tub. The outer tub is used for storing water, and the inner tub is used for accommodating the laundry. The inner tub and the outer tub are connected to allow the washing water to enter the inner tub. The inner tub rotates according to a certain rule, enabling the laundry to come into full contact with the washing water to achieve the washing of the laundry. After the washing is completed, the inner tub rotates, and part of the water on the laundry can be thrown out under the action of centrifugal force to achieve the dehydration of the laundry.

[0111] Specifically, as Figure 10 shown, the laundry treatment device further includes a housing 300, a compressor 400, and a pipeline assembly 500. The housing 300 forms the overall framework of the laundry treatment device and can accommodate other structures such as the tub assembly 200. The compressor 400 is connected to the evaporator and condenser of the air supply assembly 100 through the pipeline assembly 500, and can provide power for the circulation of the refrigerant to ensure the reliable operation of the evaporator and condenser, guaranteeing the drying effect of the laundry treatment device. Arranging the relatively large-volume compressor 400 separately from the air supply assembly 100 can reasonably utilize the space inside the housing 300 for layout. By introducing a heat pump system in the laundry treatment device while maintaining the original overall height of the machine or only slightly increasing the overall height of the machine, a heat pump washing and drying integrated machine is formed, which helps to reduce the overall size of the laundry treatment device and the space occupied by the laundry treatment device, and helps to improve the market competitiveness of the product.

[0112] Specifically, the air supply assembly 100 is arranged in the top space of the housing 300, and the compressor 400 is arranged in the bottom space of the housing 300. For example, the compressor 400 is connected to the bottom plate 320 of the housing 300, so that the compressor 400 and the air supply assembly 100 are arranged separately, which helps to reduce the space occupied by the top space of the housing 300 and reduce the overall height of the laundry treatment device.

[0113] Further, the intake port of the compressor 400 is connected to the outlet of the evaporator, and the exhaust port of the compressor 400 is connected to the inlet of the condenser. The air supply assembly 100 further includes a throttling device, such as a capillary tube, disposed between the outlet of the condenser and the inlet of the evaporator, forming a refrigerant circulation path of compressor 400 → condenser → throttling device → evaporator → compressor 400, which constitutes a heat pump system. Specifically, the refrigerant is compressed into a high-temperature and high-pressure gaseous refrigerant in the compressor 400. The high-temperature and high-pressure gaseous refrigerant is discharged from the compressor 400 through the exhaust port of the compressor 400 and then enters the condenser to condense and release heat. The high-temperature and high-pressure gaseous refrigerant gradually turns into a high-pressure liquid refrigerant. The high-pressure liquid refrigerant flows out of the condenser and enters the throttling device to be throttled to reduce the temperature and pressure. The high-pressure liquid refrigerant turns into a low-temperature and low-pressure gas-liquid mixed refrigerant. Then, the low-temperature and low-pressure refrigerant flows out of the throttling device and enters the evaporator to absorb heat from the surrounding environment and continuously evaporate, turning into a low-pressure gaseous refrigerant. The low-pressure gaseous refrigerant flows out of the evaporator and then re-enters the compressor 400 through the intake port of the compressor 400 for compression, and so on in a cycle.

[0114] Further, as Figure 6 and Figure 8 shown, the laundry treatment device further includes a connecting member 600. The connecting member 600 is connected to both the housing 300 and the air supply assembly 100 at the same time. The connecting member 600 is located on the side of the air supply assembly 100 facing away from the tub assembly 200. By providing the connecting member 600 connected to the air supply assembly 100, the air supply assembly 100 can be carried and moved by holding the connecting member 600. Specifically, the connecting member 600 can be connected to the air supply housing 110. At the same time, since the connecting member 600 is specifically connected to the side of the air supply assembly 100 facing away from the tub assembly 200, that is, facing outward, the connecting member 600 can always be exposed within the visual field and operation range of the assembly personnel, and the connecting member 600 can also always be exposed within the operation range of the automated assembly equipment. That is, during the entire assembly process, the position of the air supply assembly 100 can be adjusted through the connecting member 600, which is convenient for operation. In addition, the connecting member 600 is also connected to the housing 300. After the position of the air supply assembly 100 is adjusted, the connecting member 600 can be directly fixedly connected to the housing 300, thereby realizing the fixed connection between the air supply assembly 100 and the housing 300, and thus completing the assembly of the air supply assembly 100. In other words, by providing the connecting member 600, the handling and assembly of the air supply assembly 100 can be directly completed by using the connecting member 600, which helps to greatly improve the assembly efficiency of the air supply assembly 100 and the housing 300 and increase the production of the laundry treatment device.
