[0038] The embodiments of the present application provide a base device 10.

[0039] It should be noted that the application scenario of the base device 10 is not limited. In the embodiments of the present application, the base device 10 is described by taking its application to a laundry treatment device as an example.

[0040] The embodiments of the present application also provide a laundry treatment device. Please refer to Figure 1 and Figure 2 , the laundry treatment device includes a first cylinder assembly 20 and the base device 10 of any embodiment of the present application.

[0041] It can be understood that the specific form of the laundry treatment device is not limited. Exemplarily, the laundry treatment device can at least be used for drying clothes.

[0042] Please refer to Figures 3 to 8 , the base device 10 includes a base 11, an evaporator 14, and a condenser 15. Among them, the evaporator 14 and the condenser 15 can be collectively referred to as two devices, that is, the two devices include the evaporator 14 and the condenser 15.

[0043] The base 11 has an air duct 11a, and the air duct 11a is used to communicate with the laundry treatment chamber of the laundry treatment device.

[0044] Specifically, the air duct 11a is used for the flow of air, and the air can circulate between the air duct 11a and the laundry treatment chamber to dry the laundry.

[0045] Please refer to Figure 3 and Figure 4 , the air duct 11a has an air outlet 11b. The dry hot air flow formed after heating in the air duct 11a can flow out of the air duct 11a through the air outlet 11b and flow towards the laundry treatment chamber.

[0046] Exemplarily, please refer to Figure 1 , the first cylinder assembly 20 has a first laundry treatment chamber 21.

[0047] The air duct 11a is communicated with the first laundry treatment chamber 21. That is to say, the air can circulate between the air duct 11a and the first laundry treatment chamber 21.

[0048] Please refer to Figure 5 and Figure 8 , the air duct 11a includes a two-device installation area 11c, the evaporator 14 and the condenser 15 are arranged in the two-device installation area 11c, the evaporator 14 is arranged upstream of the condenser 15 along the air flow direction, the evaporator 14 condenses and dehumidifies the air flow, and the condenser 15 heats the air flow.

[0049] The following briefly describes the drying process and principle of the laundry treatment device in the embodiments of the present application.

[0050] When the laundry treatment device performs a drying operation on the laundry, the dry hot air flow enters the first laundry treatment chamber 21 from the air duct 11a, flows through the surface of the wet laundry, performs heat and moisture exchange with the wet laundry, absorbs the moisture in the laundry, and becomes a humid hot air flow. The humid hot air flow leaves the first laundry treatment chamber 21 and enters the air duct 11a, forms a low-temperature dry air flow after being condensed and dehumidified by the evaporator 14, and then forms a dry hot air flow after being heated by the condenser 15. The dry hot air flow enters the first laundry treatment chamber 21 again. In this way, it runs in a cycle to achieve continuous and efficient drying of the laundry.

[0051] It should be noted that the low-temperature dry air flow is relative to the humid hot air flow, and the temperature of the low-temperature dry air flow is lower than that of the humid hot air flow. The low temperature in the embodiments of the present application can be room temperature.

[0052] The base device 10 further includes a compressor. The compressor is used for compressing the refrigerant. The compressor has a suction port and an exhaust port. The compressor sucks in the refrigerant with a lower temperature and a lower pressure from the suction port, compresses the refrigerant by driving a piston through the operation of the motor, and outputs the refrigerant with an increased temperature and an increased pressure from the exhaust port.

[0053] It can be understood that the refrigerant, also known as the refrigerant medium or refrigerant, is a medium substance used to complete the heat exchange cycle.

[0054] Exemplarily, the compressor, the evaporator 14, and the condenser 15 are connected through a refrigerant circulation pipeline. The suction port of the compressor is communicated with the outlet of the evaporator 14, and the discharge port of the compressor is communicated with the inlet of the condenser 15. In this way, a refrigerant circulation loop is formed. After the compressor compresses the refrigerant, the refrigerant enters the condenser 15. The condenser 15 cools the refrigerant, and the evaporator 14 heats the refrigerant. The heated refrigerant enters the compressor again, and so on in a cycle.

[0055] The drying process and principle of the laundry treatment device are as follows: The compressor sucks in low-pressure gaseous refrigerant, compresses it, and discharges it as high-pressure gaseous refrigerant. The discharged high-pressure gaseous refrigerant enters the condenser 15. The refrigerant is cooled by the airflow around the condenser 15 and condenses into high-pressure liquid (while transferring heat to the surrounding air). That is to say, the airflow around the condenser 15 will be heated and raised in temperature to form a drying hot airflow and enter the first laundry treatment chamber 21. After the high-pressure liquid refrigerant flows through the throttling device for throttling and pressure reduction, it becomes a low-temperature and low-pressure gas-liquid two-phase mixture. The gas-liquid two-phase mixture enters the evaporator 14. The liquid refrigerant therein evaporates and refrigerates in the evaporator 14 (while absorbing heat from the surrounding air). That is to say, the airflow around the evaporator 14 will be cooled and lowered in temperature to form a low-temperature drying airflow. The low-pressure gaseous refrigerant is sucked into the compressor again for pressurization, and so on in a cycle, continuously circulating to achieve heat exchange and realize continuous and efficient drying of the laundry.

[0056] Please refer to Figure 8 , the air duct 11a includes a diversion area 11e, and the diversion area 11e communicates with the two-device installation area 11c and the air outlet 11b. That is to say, the diversion area 11e is located downstream of the two-device installation area 11c along the airflow direction. The diversion area 11e is used to direct the airflow flowing through the two-device installation area 11c to the air outlet 11b. The airflow is dehumidified by the evaporator 14 and heated by the condenser 15, and then is directed to the air outlet 11b through the diversion area 11e, and then can flow to the laundry treatment chamber of the laundry treatment device through other paths.

[0057] Exemplarily, the base 11 includes a bottom case 111 and a top cover 112. The top cover 112 is disposed on the top side of the bottom case 111, and the two define the air duct 11a.

[0058] Exemplarily, the base device further includes an electric auxiliary heating device 13, and the electric auxiliary heating device 13 is used to heat the airflow.

[0059] Please refer to Figure 5 and Figure 7, the electric auxiliary heating device 13 is arranged in the diversion area 11e. That is to say, the electric auxiliary heating device 13 is arranged downstream of the condenser 15 along the air flow direction. In this way, after the air flow is heated by the condenser 15, it can be reheated by the electric auxiliary heating device 13, so as to increase the drying temperature and improve the drying efficiency.

[0060] Specifically, when the ambient temperature is relatively low and the heating temperature is relatively low, the electric auxiliary heating device 13 can be turned on to further heat the air flow passing through the condenser 15. The heated air flow is guided to the air outlet 11b under the action of the diversion area 11e and flows to the laundry processing chamber of the laundry processing device through the air outlet 11b.

[0061] Exemplarily, the base device 10 includes an impeller for generating negative pressure in the air duct 11a. The air flow assisted by heating by the electric auxiliary heating device 13 flows to the air outlet 11b under the action of the negative pressure. In some embodiments, the impeller can be arranged downstream of the air outlet 11b, that is to say, the fan is not arranged in the air duct 11a. Of course, in other embodiments, the impeller can also be arranged in the air duct 11a.

[0062] Please refer to Figure 8 , the two-device installation area 11c extends along the first direction, that is, the air flow passing through the two-device installation area 11c generally flows along the first direction. That is, the evaporator 14 and the condenser 15 described above are arranged along the first direction.

[0063] The diversion area 11e extends towards the side of the two-device installation area 11c along the second direction, where the first direction and the second direction are perpendicular. It should be noted that the side of the two-device installation area 11c along the second direction refers to the lateral orientation of the two-device installation area 11c, and the fact that the diversion area 11e extends towards the side of the two-device installation area 11c along the second direction refers to the deflection trend of the diversion area 11e, rather than limiting that the diversion area 11e extends along the second direction.

[0064] Exemplarily, the first direction, the second direction, and the height direction of the base device 10 are perpendicular to each other pairwise. The first direction can be the left-right direction or the front-back direction of the laundry processing device. The left-right direction and the front-back direction are the directions in which the laundry processing device is located in the normal use state. Specifically, the side where the door body of the laundry processing device is located and / or the side facing the user is the front side, and the side opposite to the front side is the rear side. The side of the laundry processing device facing the user's left hand is the left side, and the side facing the user's right hand is the right side.

[0065] That is to say, the dimension of the air duct 11a along the first direction is approximately the extension dimension of the two-device installation area 11c along the first direction. During the flow of the air flow from the two-device installation area 11c to the air outlet 11b, it undergoes at least one commutation.

[0066] It can be understood that in the related art, due to the limited installation space, the distance between the electric auxiliary heating device and the condenser is close, and the working temperature of the electric auxiliary heating device is likely to affect the operation of the condenser, which is not conducive to the effective heating of the air flow.

[0067] However, for the base device provided in the embodiment of the present application, the arrangement of the two-device installation area 11c and the diversion area 11e can facilitate the reasonable layout of the positions and distances of the condenser 15 and the electric auxiliary heating device 13 without increasing the size of the base device 10 in the first direction, improving the working reliability of the condenser 15. The electric auxiliary heating device 13 can also effectively perform auxiliary heating to improve the overall drying efficiency. The overall size of the base device 10 is reasonable, with high space utilization and high structural compactness.

[0068] In some embodiments, please refer to Figure 5 and Figure 7 , the electric auxiliary heating device 13 is arranged at one end of the diversion area 11e close to the two-device installation area 11c.

[0069] In this way, while reasonably arranging the distance between the electric auxiliary heating device 13 and the condenser 15, it is also convenient for the electric auxiliary heating device 13 to timely and effectively assist in heating the air flow flowing out of the condenser 15, improving the drying performance.

[0070] In some embodiments, please refer to Figure 6 and Figure 8 , the diversion area 11e has a contraction section 11f and a transition section 11g. The contraction section 11f is connected to the two-device installation area 11c, and the transition section 11g connects the end of the contraction section 11f and the air outlet 11b.

[0071] Specifically, the air flow passing through the two-device installation area 11c flows through the contraction section 11f and the transition section 11g in sequence and then flows to the air outlet 11b.

[0072] It can be understood that the end of the contraction section 11f refers to the tail end of the contraction section 11f along the air flow direction. The head end of the contraction section 11f is connected to the two-device installation area 11c. The contraction section 11f intakes air at the head end and discharges air at the end.

[0073] Please refer to Figure 6 and Figure 8 , along the air flow direction, the flow cross-sectional area of the contraction section 11f decreases. It should be noted that the decrease in the flow cross-sectional area of the contraction section 11f refers to the area where the flow cross-sectional area as a whole shows a decrease, which can be a continuous decrease or a stepwise decrease.

[0074] It should be noted that the flow cross-sectional area refers to the cross-sectional area through which the air flow passes. For example, when the height of the contraction section 11f remains unchanged, the flow cross-sectional area region is the width of the contraction section 11f. That is, the width of the contraction section 11f decreases along the air flow direction. Among them, the width of the contraction section 11f can be understood as: the diameter corresponding to the largest sphere that can pass through each part of the contraction section 11f.

[0075] In this embodiment, the setting of the contraction section 11f is beneficial to guiding the air flow, can also accelerate the air flow velocity, facilitate the air flow to concentrate and flow through the transition section 11g to the air outlet 11b, and increase the air outlet reliability.

[0076] Exemplarily, the electric auxiliary heating device 13 can be arranged at one end of the contraction section 11f close to the condenser 15. That is to say, the electric auxiliary heating device 13 is as close as possible to the air inlet position of the contraction section 11f. In this way, the electric auxiliary heating device 13 can have sufficient layout space, and the size of the electric auxiliary heating device 13 can be larger, which is beneficial to ensuring the heating power of the electric auxiliary heating device 13 and the heating effect on the air flow.

[0077] In some embodiments, please refer to Figures 4 to 8 , in the orthographic projection on the plane perpendicular to the first direction, at least part of the air outlet 11b is located on one side of the condenser 15 along the second direction.

[0078] It can be understood that at least part of the air outlet 11b being located on one side of the condenser 15 along the second direction can be that part of the air outlet 11b is located on one side of the condenser 15 along the second direction, and the other part falls within the range where the condenser 15 is located; it can also be that the entire air outlet 11b is located on one side of the condenser 15 along the second direction.

[0079] Please refer to Figure 4 and Figure 5 , from the end of the electric auxiliary heating device 13 close to the air outlet 11b to the end far from the air outlet 11b, the electric auxiliary heating device 13 extends obliquely in the direction away from the side where the condenser 15 is located.

[0080] In this embodiment, the obliquely arranged electric auxiliary heating device 13 helps the air flow to pass through the electric auxiliary heating device 13 as close as possible to the vertical direction, which is beneficial to the air flow passing through the central area of the electric auxiliary heating device 13 more concentratedly and improving the heating efficiency.

[0081] It should be noted that in the embodiment where the electric auxiliary heating device 13 extends obliquely in the direction away from the side where the condenser 15 is located, the extension obliquely in the direction away from the side where the condenser 15 is located refers to the orientation. For example, taking the first direction as the front-back direction, the air outlet 11b is arranged at the rear side, and the condenser 15 is located at the front side of the electric auxiliary heating device 13 in Figure 5 above, then the direction away from the side where the condenser 15 is located refers toFigure 5 the rear side in Figure 8 extends obliquely forward in

[0082] It can be understood that the specific structure of the electric auxiliary heating device 13 is not limited. Exemplarily, the electric auxiliary heating device 13 can be a PTC (Positive Temperature Coefficient, thermistor) heater, a resistance wire, etc.

[0083] It can be understood that the electric auxiliary heating device 13 can be powered by a cable to achieve the electric heating function.

[0084] Exemplarily, the base device 10 includes a seal 12.

[0085] The seal 12 is clamped between the bottom shell 111 and the top cover 112. The seal 12 is provided with a wire routing channel, and the cable passes through the wire routing channel and is electrically connected to the electric auxiliary heating device 13.

[0086] The wire routing channel in the seal 12 is for the cable to pass through. The wire routing channel protects the cable so that the cable is not affected by external wear and abrasion, and increases the sealing performance of the air duct 11a.

[0087] In some embodiments, please refer to Figure 5 , the extending direction of the electric auxiliary heating device 13 intersects with the extending direction of the condenser 15. Specifically, the distance between the end of the electric auxiliary heating device 13 close to the air outlet 11b and the condenser 15 is less than the distance between the end of the electric auxiliary heating device 13 far from the air outlet 11b and the condenser 15.

[0088] It can be understood that the extending direction of the electric auxiliary heating device 13 intersecting with the extending direction of the condenser 15 means that the extending direction of the electric auxiliary heating device 13 is not parallel to the extending direction of the condenser 15, and the extending direction of the electric auxiliary heating device 13 and the extending direction of the condenser 15 are arranged at an angle.

[0089] Exemplarily, the condenser 15 can extend along the second direction, and the electric auxiliary heating device 13 extends obliquely with respect to the condenser 15.

[0090] In this embodiment, the extending direction of the electric auxiliary heating device 13 is not the same as the extending direction of the condenser 15. In this way, it is convenient to correspondingly adjust the distance between the electric auxiliary heating device 13 and the condenser 15, and it is adapted to the flowing direction of the air flow, increasing the air flow circulation efficiency.

[0091] In other embodiments, the extending direction of the electric auxiliary heating device 13 is parallel to the extending direction of the condenser 15.

[0092] That is to say, the extending direction of the electric auxiliary heating device 13 is the same as that of the condenser 15, and in the extending direction, the distances between the various parts of the electric auxiliary heating device 13 and the condenser 15 are the same.

[0093] In this embodiment, the extending direction of the electric auxiliary heating device 13 is the same as that of the condenser 15, which is convenient for the layout of the electric auxiliary heating device 13 and the condenser 15.

[0094] In some embodiments, please refer to Figure 8 , the included angle α formed by the extending direction of the electric auxiliary heating device 13 and the second direction is greater than 0° and not more than 30°, that is, 0° < α ≤ 30°. Exemplarily, 0°, 5°, 10°, 12°, 16°, 19°, 21°, 24°, 25°, 27°, 30°, etc.

[0095] In this embodiment, the included angle between the extending direction of the electric auxiliary heating device 13 and the second direction is appropriate, which is convenient for receiving the air flow from the condenser 15, making the air flow pass through the electric auxiliary heating device 13 more smoothly. At the same time, it is also beneficial for the air flow to pass through the electric auxiliary heating device 13 in a direction as perpendicular as possible, improving the heating efficiency.

[0096] In some embodiments, the extending length of the electric auxiliary heating device 13 is less than that of the condenser 15.

[0097] In this embodiment, the setting of the extending length of the electric auxiliary heating device 13 can reduce the space occupied by the electric auxiliary heating device 13 while assisting in heating, making the layout of the base device 10 more compact and reasonable.

[0098] The installation method of the electric auxiliary heating device 13 in the air duct 11a is not limited.

[0099] In some embodiments, the base device 10 includes at least one installation structure 1112, and the installation structure 1112 defines a slot 1112a, and at least part of the structure at at least one end of the electric auxiliary heating device 13 along its extending direction is inserted into the slot 1112a.

[0100] It can be understood that at least part of the structure at at least one end of the electric auxiliary heating device 13 along its extending direction is inserted into the slot 1112a, including various situations.

[0101] The first case: Part of the structure at one end of the electric auxiliary heating device 13 along its extending direction is inserted into the slot 1112a.

[0102] The second case: All of the structure at one end of the electric auxiliary heating device 13 along its extending direction is inserted into the slot 1112a.

[0103] The third case: Part of the structures at both ends of the electric auxiliary heating device 13 along its extending direction are inserted into the slot 1112a.

[0104] The fourth type: Part of the structure at one end of the electric auxiliary heating device 13 along its extending direction is inserted into the slot 1112a, and all the structures at the other end along its extending direction are inserted into the slot 1112a.

[0105] The fifth type: All the structures at both ends of the electric auxiliary heating device 13 along its extending direction are inserted into the slot 1112a.

[0106] In this embodiment, the setting of the slot 1112a can provide an installation space for the electric auxiliary heating device 13, and at the same time, can support and position the electric auxiliary heating device 13, increasing the installation stability of the electric auxiliary heating device 13 and reducing the influence of the electric auxiliary heating device 13 caused by air flow or the vibration of the base device 10. Moreover, the electric auxiliary heating device 13 can also be positioned through the slot 1112a, increasing the installation reliability, and at the same time, it is also convenient to disassemble the electric auxiliary heating device 13, with high operation convenience.

[0107] The number of the installation structures 1112 can be one or multiple, which is not limited here.

[0108] It can be understood that the forming method of the slot 1112a is not limited, as long as it can install and limit the electric auxiliary heating device 13.

[0109] The specific structure of the installation structure 1112 is not limited. Exemplarily, please refer to Figure 6 and Figure 7 , the number of the installation structures 1112 can be two. One installation structure 1112 is arranged at one end of the electric auxiliary heating device 13 along the extending direction away from the air outlet 11b, and the other installation structure 1112 is arranged at one end of the electric auxiliary heating device 13 along the extending direction close to the air outlet 11b. Each installation structure 1112 includes two limiting plates 1113, and the two limiting plates 1113 are arranged at intervals along the direction perpendicular to the extending direction of the electric auxiliary heating device 13, so as to define the slot 1112a. Both ends of the electric auxiliary heating device 13 along the extending direction are arranged in the slot 1112a. In this way, the installation stability of the electric auxiliary heating device 13 is high.

[0110] In some embodiments, the base 11 includes a bottom wall 1111, and the bottom wall 1111 forms a first support surface 1111a and a second support surface 1111b. The first support surface 1111a is used to support the electric auxiliary heating device 13, and the second support surface 1111b is used to support the condenser 15 and the evaporator 14.

[0111] Please refer to Figure 4 , Figure 6 and Figure 7 , the position of the first support surface 1111a is higher than that of the second support surface 1111b. In this way, a step structure is formed between the second support surface 1111b and the first support surface 1111a.

[0112] That is, in the height direction of the base device 10 , there is a height difference between the first supporting surface 1111 a and the second supporting surface 1111 b .

[0113] In this embodiment, the height difference design between the first supporting surface 1111a and the second supporting surface 1111b is such that the installation position of the bottom of the electric auxiliary heating device 13 is higher than the installation position of the bottom of the evaporator 14 and the condenser 15. The step structure can block the condensed water flowing along the first supporting surface 1111a (the condensed water may flow downstream along the first supporting surface 1111a in the direction of air flow under the action of the negative pressure in the air duct), thereby reducing the probability of the condensed water contacting the electric auxiliary heating device 13, increasing the working reliability of the electric auxiliary heating device 13, and increasing the drying efficiency.

[0114] In some embodiments, the base device 10 includes a stop rib 1114 , which is disposed on the first supporting surface 1111 a and located at the air outlet side of the electric auxiliary heating device 13 .

[0115] See also Figure 4 , Figure 6 and Figure 7 , the top surface of the stopping rib 1114 is located higher than the first supporting surface 1111a.

[0116] That is, in the height direction of the base device 10 , there is a height difference between the top surface of the stopping rib 1114 and the first supporting surface 1111 a .

[0117] It can be understood that the side of the electric auxiliary heating device 13 facing the condenser 15 is the windward side of the electric auxiliary heating device 13, and the side of the electric auxiliary heating device 13 facing away from the condenser 15 is the windward side of the electric auxiliary heating device 13. The airflow passing through the condenser 15 is first heated by the windward side of the electric auxiliary heating device 13, and then flows to the air outlet 11b through the windward side of the electric auxiliary heating device 13.

[0118] In this embodiment, the provision of the stopping rib 1114 can further stop the condensed water and further increase the drying reliability.

[0119] For some examples, see Figures 5 to 7 The side wall of the air duct 11a includes a first side wall 1115, the first side wall 1115 is located on one side of the condenser 15 along the first direction, the air outlet 11b is arranged on the first side wall 1115, and an arc-shaped guide surface 1115a is formed on the side of the first side wall 1115 facing the electric auxiliary heating device 13, and one end of the electric auxiliary heating device 13 away from the air outlet 11b cooperates with the arc-shaped guide surface 1115a, and the arc-shaped guide surface 1115a is used to guide the airflow flowing through the electric auxiliary heating device 13 to the air outlet 11b.

[0120] It can be understood that one end of the electric auxiliary heating device 13 away from the air outlet 11b cooperates with the arc-shaped guiding surface 1115a. It can be that one end of the electric auxiliary heating device 13 away from the air outlet 11b is arranged close to the arc-shaped guiding surface 1115a. The electric auxiliary heating device 13 can be connected to the arc-shaped guiding surface 1115a through the mounting structure 1112. In this way, the electric auxiliary heating device 13 is located on the flow path of the air flow flowing out of the condenser 15. The air flow flowing out of the condenser 15 can first pass through the electric auxiliary heating device 13 and then flow towards the air outlet 11b, improving the drying temperature.

[0121] The design of the arc-shaped guiding surface 1115a can not only guide the air flow but also reduce the flow resistance of the air flow, facilitating the smooth flow of the air flow towards the air outlet 11b, increasing the air outlet efficiency, and further improving the drying efficiency.

[0122] It can be understood that the bottom wall of the guiding area 11e is connected to the first side wall 1115. Under the combined action of the guiding area 11e and the arc-shaped guiding surface 1115a of the first side wall 1115, the air flow flows towards the air outlet 11b.

[0123] In some embodiments, please refer to Figure 1 and Figure 2 , the laundry treatment device includes a cabinet, a second cylinder assembly 30, and a rack 40 disposed in the cabinet.

[0124] The rack 40 is the main support structure for the fixed installation and support of other components of the laundry treatment device.

[0125] The base device 10 is disposed on the rack, and the base device 10 and its load transfer the acting force to the rack 40.

[0126] Exemplarily, in some embodiments, the rack 40 includes at least four columns, and the four columns extend along the height direction respectively. In the horizontal plane projection, the four columns are distributed at the four vertices of a quadrilateral.

[0127] In the embodiments of the present application, the height direction is Figure 1 the direction shown in

[0128] which includes both the direction from top to bottom and the direction from bottom to top.

[0129] Exemplarily, the base device 10 can be respectively connected to the above four columns. The base device 10 is located within the area defined by the four columns.

[0130] In some embodiments, the first laundry treatment chamber 21 can at least perform a drying treatment on laundry. The second cylinder assembly 30 has a second laundry treatment chamber 31, and the second laundry treatment chamber 31 can at least perform a washing treatment on laundry.

[0131] In some embodiments, the first space is located above the second space, that is, the position of the first cylinder assembly 20 is higher than the position of the second cylinder assembly 30.

[0132] In some other embodiments, the first space can also be located below the second space, that is, the position of the second cylinder assembly 30 is higher than the position of the first cylinder assembly 20.

[0133] In some embodiments, a partial structure of the bottom wall 1111 protrudes upward to form an avoidance space 11d at the bottom side of the bottom wall 1111 for avoiding the cylinder assembly of the laundry treatment device.

[0134] Specifically, please refer to Figure 1 , the avoidance space 11d is used to avoid a partial structure of the second cylinder assembly 30, so that the structure of the laundry treatment device is compact and the overall height of the laundry treatment device is reduced.

[0135] The air duct 11a includes a two-device installation area 11c for installing two devices. Here, the two devices refer to the evaporator 14 and the condenser 15, and the evaporator 14 and the condenser 15 are installed in the two-device installation area 11c.

[0136] The base 11 further includes a power mechanism installation area 111a located outside the air duct 11a. The compressor is disposed in the power mechanism installation area 111a, and the power mechanism installation area 111a is disposed on one side of the two-device installation area 11c along the first direction.

[0137] That is to say, the compressor is disposed outside the air duct 11a. In this way, it is convenient for the air to circulate around the compressor, enhancing the heat dissipation effect, and reducing the influence of the heat generated by the compressor on the evaporator 14 and the condenser 15 in the air duct 11a. At the same time, it is also convenient for disassembling, assembling and maintaining the compressor without affecting the structure in the air duct 11a.

[0138] The position of the bottom wall of the power mechanism installation area 111a is lower than the bottom wall of the two-device installation area 11c. In this way, a stepped structure can be formed, which is convenient for installing the compressor at a lower position, reducing the overall center of gravity of the base device 10, and also convenient for installing and maintaining the compressor, making the layout of the base device 10 more compact.

[0139] In some embodiments, please refer to Figure 7 , the bottom wall of the two-device installation area 11c is a horizontal plate-like structure; the two devices are supported on the horizontal plate-like structure.

[0140] It can be understood that the horizontal plate-like structure means that the plane where the bottom wall of the two-vessel installation area 11c is located is parallel to the horizontal plane.

[0141] In this embodiment, the two vessels are arranged on the horizontal plate-like structure. The evaporator 14 and the condenser 15 can be stably arranged in the two-vessel installation area 11c. The two-vessel installation area 11c can evenly bear the weights of the evaporator 14 and the condenser 15. And when it is necessary to adjust the installation positions of the evaporator 14 and the condenser 15, it can also be carried out in the same plane without complex three-dimensional space adjustment. At the same time, the design of the horizontal plate-like structure can also reduce the manufacturing difficulty of the base 11 and increase the structural reliability of the base device 10.

[0142] In some embodiments, the position of the horizontal plate-like structure is the highest position of the avoidance space 11d.

[0143] Specifically, the horizontal plate-like structure can serve as the top boundary of the avoidance space 11d to provide protection for the cylinder assembly or other components of the clothing treatment device below and reduce damage.

[0144] Exemplarily, the horizontal plate-like structure can be used as a platform for separating the first cylinder assembly 20 and the second cylinder assembly 30. While providing support, the horizontal plate-like structure can also increase the layout reliability of the first cylinder assembly 20 and the second cylinder assembly 30.

[0145] In this embodiment, the installation position of the compressor is relatively low, and the overall center of gravity of the base device 10 is low. Without increasing the overall height of the clothing treatment device, the overall structure of the clothing treatment device can be made more compact.
