Description

Technical Field

[0001] The present invention relates to the technical field of washing equipment, and particularly relates to a laundry treatment device with a heat pump drying function. Background Art

[0002] With the improvement of living standards, people pursue a safer and more comfortable laundry drying experience. However, for the mainstream laundry treatment devices with a separate drying function or a washing-drying integrated function on the market currently, their main drying method is the electric heating method, which has problems of high power consumption and poor drying effect. Therefore, the market mainstream is gradually turning to the research of heat pump drying.

[0003] Heat pump drying not only saves energy but also can not damage clothes. However, there is still an unavoidable problem with the heat pump drying system, that is, the heat pump drying module will inevitably cause the overall size of the machine to be relatively large. The overall size specification is different from that of a conventional washing machine, which will make the placement position and space of the commonly used laundry treatment device in the family unable to be universalized, which is a common headache for current consumers.

[0004] Therefore, the present invention aims to solve the problem of how to put the heat pump drying system into a laundry treatment device to achieve the effect of heat pump drying on the premise of the size specification of the existing conventional laundry treatment device. Moreover, without affecting the drying efficiency and effect, it is necessary to solve the problem of space utilization in the existing conventional laundry treatment device.

[0027] As an alternative embodiment of the present invention, an outer cylinder avoidance area for avoiding the installation of the two-component box is provided at a position on the outer peripheral wall of the outer cylinder opposite to the two-component box.

[0028] Beneficial effects:

[0029] Combined with the spatial layout in the housing, the evaporator and the condenser of the present invention are arranged in the upper left or upper right space of the inner and outer cylinders of the housing, mainly considering the arrangement of the structural components in the housing, and improving the utilization rate of the internal space of the washing machine housing. Specifically, a detergent dispenser is generally arranged in the upper left of the inner and outer cylinders of the housing of the existing laundry treatment device. Therefore, the evaporator and the condenser can be arranged in the upper right space of the inner and outer cylinders of the housing; if it is considered to arrange the detergent dispenser in the upper right of the inner and outer cylinders of the housing, then the evaporator and the condenser can be arranged in the upper left space of the inner and outer cylinders of the housing.

[0030] The evaporator and condenser of the present invention are arranged in the limited space inside the housing.

[0032] The cross-section of the heat exchange body of the evaporator and / or condenser of the present invention perpendicular to the axis of the outer cylinder is in the shape of being wider at the top and narrower at the bottom. This is because the outer cylinder is a cylindrical structure and the housing is a cuboid structure. The space in the upper left or upper right between the housing 1 and the outer cylinder is in the shape of being wider at the top and narrower at the bottom. In order to make full use of the space, the heat exchange body of the evaporator and / or condenser is adapted to be in the shape of being wider at the top and narrower at the bottom, maximizing the cross-sectional area of the heat exchange body of the two-device module to improve the heat pump drying effect.

[0035] 2. It can effectively ensure the drying time and drying effect;

[0036] 3. It can reduce the space occupied by the heat pump drying module. Description of the Drawings

[0063] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

"Plural" generally includes at least two, but does not exclude the case of including at least one.

[0065] It should be understood that the term " / and / " used herein is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0066] It should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a commodity or system comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such commodity or system. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the commodity or system comprising said element.

[0067] To further elaborate on the technical solutions in the present invention, in combination with Figures 1 - 25 , the following specific embodiments are provided.

[0068] See Figure 1 and Figure 2 As shown, this embodiment provides a laundry treatment device with a heat pump drying function, which may specifically be a drum washing machine with a heat pump drying function, or a heat pump drum dryer and other laundry treatment devices with a heat pump drying function. Specifically, the drum washing machine with a heat pump drying function in the present invention is taken as an example for elaboration, but it can also be applied to a heat pump drum dryer by those skilled in the art.

[0069] This embodiment provides a laundry treatment device with a heat pump drying function, including a housing 1. An inner drum 3 and an outer drum 2 are coaxially installed inside the housing 1, and the outer drum 2 is installed inside the housing 1 through a vibration damping module; the inner drum 3 is driven by a driving motor and is rotatably arranged inside the outer drum 2.

[0070] During the laundry process of the laundry treatment device, washing water enters the outer drum 2 through a water inlet pipeline. After reaching the set water level, the water inlet stops. The inner drum 3 is driven by the driving motor to rotate inside the outer drum 2, and the laundry is washed by lifting and beating the laundry during the rotation of the inner drum 2.

[0071] As Figure 1 shown, the laundry treatment device is vertically placed on a horizontal ground. A panel assembly 8 is provided in front of the housing 1 of the laundry treatment device. A feeding port is opened on the panel assembly 8, and a door body assembly 9 is installed on the feeding port of the panel assembly 8 for opening / closing the feeding port. See Figure 1 for the orientation marks in it. For the direction definitions of up, down, front, back, left, and right involved in the present invention, examples are given to better explain the technical solutions of the present invention.

[0072] Furthermore, the laundry treatment device in this embodiment has a drying function, and it is a heat pump drying method realized through a heat pump system. Considering the problem of the working efficiency of the heat pump in existing laundry treatment devices, sufficient space generally needs to be reserved inside the housing to install the heat pump system, thus resulting in an increase in the housing of the washing machine.

[0073] Therefore, a laundry treatment device with a heat pump drying function proposed by the present invention has a heat pump system including an evaporator, a condenser, a compressor, and a fan assembly. The fan assembly conveys the humid and hot drying air in the outer cylinder to the evaporator. The evaporator exchanges heat with the humid and hot drying air to condense the moisture in the humid and hot drying air into dry and cold drying air. The dry and cold drying air is conveyed to the condenser for heat exchange to be heated into dry and hot drying air. The dry and hot drying air is introduced into the outer cylinder to dry the laundry and then becomes humid and hot drying air again, and the cycle is repeated. The refrigerant, which is the working medium of the heat pump system, circulates among the condenser, the throttling device, the evaporator, and the compressor. The refrigerant absorbs heat in the evaporator to cool and dehumidify the humid and hot drying air led out from the outer cylinder, and releases heat in the condenser to heat the dry and cold drying air led out from the evaporator.

[0074] The present invention aims to provide a laundry treatment device with a heat pump drying function. Considering the internal space layout of the housing of the laundry treatment device, the internal space of the housing is fully utilized to implement the setting of the heat pump system, ensuring the drying efficiency and drying effect, and keeping the housing of the laundry treatment device with a heat pump drying function the same size as that of a common corresponding kilogram-level laundry treatment device.

[0075] Example 1

[0076] In this embodiment, the evaporator and the condenser are structurally designed and installed, so as to ensure that the evaporator and the condenser can be adapted to the installation in the internal space of the housing, improve the utilization rate of the internal space of the housing, and effectively control the overall height of the machine. The specific technical solution is as follows:

[0077] See Figures 1 - 9 As shown in the figure, a laundry treatment device with a heat pump drying function in this embodiment includes:

[0078] A housing 1, which forms an internal space;

[0079] An outer cylinder 2, arranged in the internal space of the housing 1;

[0080] A heat pump module, including a two-device assembly. The two-device assembly includes an evaporator 441 and a condenser 442. The evaporator 441 and / or the condenser 442 is arranged in the upper left space or the upper right space of the housing 1 and the outer cylinder 2. The heat exchange body of the evaporator 441 and / or the condenser 442 has an outer contour adapted to the upper left space or the upper right space where it is located.

[0081] In this embodiment, according to the structural characteristics of the upper left or upper right space inside the housing of the laundry treatment device. Specifically, for a drum washing machine, generally, a detergent dispensing device needs to be arranged in the upper left space, and there is a certain idle space in the upper right space opposite to the upper left space. Therefore, according to the characteristics of the internal space of the housing, the two-component assembly of this embodiment is arranged in the upper left space or the upper right space between the inner and outer drums 2 of the housing 1. Further, since the upper left space or the upper right space between the inner and outer drums 2 of the housing 1 is limited, and at the same time, in order to ensure that the overall height dimension of the laundry treatment device remains unchanged, and in order to improve the heat exchange efficiency as much as possible and ensure the drying effect, it is necessary to increase the heat exchange body of the two-component assembly as large as possible. Therefore, the heat exchange body of the evaporator 441 and / or the condenser 442 of this embodiment has an outer contour adapted to the upper left space or the upper right space where it is located. Specifically, the heat exchange body of the evaporator 441 and / or the condenser 442 of this embodiment having an outer contour adapted to the upper left space or the upper right space where it is located means that the heat exchange body adopts an irregular layout method, but is adapted to the installation space to ensure the drying efficiency.

[0082] As an alternative embodiment of this embodiment, the cross-section of the heat exchange body of the evaporator 441 and / or the condenser 442 perpendicular to the axis of the outer drum is in the shape of being wider at the top and narrower at the bottom. This is because the outer drum 2 is a cylindrical structure, the housing 1 is a cuboid structure, and the upper left space or the upper right space between the housing 1 and the outer drum 2 is in the shape of being wider at the top and narrower at the bottom. In order to make full use of the space, the heat exchange body of the evaporator 441 and / or the condenser 442 is adapted to be in the shape of being wider at the top and narrower at the bottom.

[0083] As an alternative embodiment of this embodiment, the cross-section is in the shape of an approximate stepped surface or an approximate inverted L shape. In this way, not only can the installation space inside the housing 1 be fully utilized, but also it is convenient for the processing and manufacturing of the evaporator 441 and / or the condenser 442.

[0084] This embodiment combines the space layout inside the housing 1 and arranges the evaporator 441 and the condenser 442 in the upper left or upper right space between the inner and outer drums 2 of the housing 1, mainly considering the arrangement of the structural components inside the housing 1. Specifically, generally, a detergent dispensing box is arranged in the upper left of the inner and outer drums 2 of the housing 1 of the existing laundry treatment device. Therefore, the evaporator 441 and the condenser 442 can be arranged in the upper right space between the inner and outer drums 2 of the housing 1; if it is considered to arrange the detergent dispensing box in the upper right of the inner and outer drums 2 of the housing 1, then the evaporator 441 and the condenser 442 can be arranged in the upper left space between the inner and outer drums 2 of the housing 1.

[0085] The evaporator 441 and the condenser 442 of this embodiment are arranged in the limited space inside the housing 1. In order to ensure the drying efficiency and drying effect of the evaporator 441 and the condenser 442, the existing regular rectangular or square evaporator 441 and condenser 442 are not suitable for making full use of the space inside the housing 1 and cannot meet the drying efficiency.

[0086] Therefore, the shape of the heat exchange body of the evaporator 441 and / or the condenser 442 of this embodiment is adapted to the space between the housing 1 and the outer cylinder 2. That is to say, the overall structure of the evaporator 441 and / or the condenser 442 is designed with an adaptable shape according to the installation space, and it is no longer a regular rectangle, which can not only make full use of the installation space inside the housing, but also ensure the heat exchange efficiency.

[0087] As an alternative implementation of this embodiment, the heat exchange body of the evaporator 441 and / or the condenser 442 of this embodiment has a first horizontal side close to the top wall of the housing 1, a second horizontal side far from the top wall of the housing 1, a first vertical side close to the side wall of the housing 1 on the corresponding side, and a second vertical side far from the side wall of the housing 1 on the corresponding side. The length of the second horizontal side is greater than the length of the first horizontal side, and the height of the first vertical side is greater than the height of the second vertical side. Due to the cylindrical structure of the outer cylinder 2 and the flat structure of the housing, the horizontal length of the space between the housing 1 and the outer cylinder 2 gradually decreases from top to bottom in the vertical direction. Therefore, in order to adapt to the installation space, the horizontal distance of the first horizontal side of the heat exchange body of the evaporator 441 and / or the condenser 442 close to the outer cylinder 2 is less than the horizontal distance of the second horizontal side far from the outer cylinder 2.

[0088] For the convenience of assembling the condenser and the evaporator, as an alternative implementation of this embodiment, see Figure 5 As shown, the condenser 442 and the evaporator 441 of this embodiment are integrated into a two-device module 44. The heat exchange bodies of the condenser 442 and the evaporator 441 each include a first heat exchange part 4421 and a second heat exchange part 4421 with unequal horizontal lengths, so that the heat exchange body of the two-device module 44 has a stepped surface with a horizontal length far from the outer cylinder side greater than that close to the outer cylinder side. In order to make better use of this part of the space, the cross-section of the heat exchange body of the two-device module 44 is set to a non-rectangular structure, that is, in this space, the cross-section shape of the heat exchange body of the two-device module 44 is set to an "L" shape, a "7" shape, etc., and placed in this space to maximize the cross-sectional area of the heat exchange body of the two-device module 44 to improve the heat pump drying effect.

[0089] See Figure 5As shown, as an optional implementation of this embodiment, the evaporator 441 and the condenser 442 both have a first heat exchange part 4451 away from the outer tube 2 and a second heat exchange part 4452 close to the outer tube 2, the first heat exchange part 4451 is formed by a first heat exchange tube 4453 of a first length inserted in the first fin, and the second heat exchange part 4452 is formed by a second heat exchange tube 4455 of a second length inserted in the second fin, and the length of the first heat exchange tube 4453 is greater than the length of the second heat exchange tube 4455.

[0090] The first heat exchange part 4453 and the second heat exchange part 4455 described in this embodiment are connected by the third heat exchange tube 4454, and the third heat exchange tube 4454 includes a first tube segment inserted in the first fin and having the same length as the first heat exchange tube 4453, a second tube segment inserted in the second fin and having the same length as the second heat exchange tube 4455, and a third tube segment connecting the first tube segment and the second tube segment.

[0091] The two-device module 44 of this embodiment includes a condenser 441 and an evaporator 442, both of which are obtained by inserting copper tubes through fins, and are used to generate heat and absorb heat respectively; and the space enclosed by the outer tube 2 and the shell 1 is used to maximize the cross-sectional area of ​​the heat exchange body of the two-device module 44 and place it in the space; wherein the heat exchange body of the evaporator 441 and the condenser 442 is stepped, and the copper tube flow path is inserted in the fins, and the stepped cross section is connected by a long and short U-shaped third heat exchange tube 4454, so that the copper tube flow path of the stepped surface is connected, and the evaporator 441 and the condenser 442 are integrated in structure and easy to assemble; at the same time, the copper tube flow path is penetrated as a single inlet and a single outlet, thereby improving the utilization rate of the heat pump refrigerant medium.

[0092] Furthermore, the two-device assembly described in this embodiment includes a two-device box, and the two-device module 44 is arranged in the two-device box; the two-device box is fixed on the shell 1 and is located at the upper left or upper right of the outer tube 2, and there is a gap between the two-device box and the outer tube peripheral wall of the outer tube 2. The two-device box of this embodiment includes a two-device box body 443 and a two-device box cover 444, the two-device box body 443 has an internal accommodating cavity with one end open inside, and the two-device box cover 444 is sealed on the open end of the two-device box body 443 to form a closed space, and the two-device module 44 is placed in the internal closed space of the two-device box, and the space between the outer tube 2 and the shell 1 is also used, and this space is called an effective space, and a certain safety gap is reserved between the outer tube 2 and the shell 1.

[0093] As an alternative implementation of this embodiment, the outer wall surface of the two-component box on the side opposite to the outer peripheral wall of the outer cylinder is an inwardly concave arc surface 4434. The inwardly concave arc surface 4434 and the outer peripheral wall of the outer cylinder share the same central axis, and there is a gap between the inwardly concave arc surface 4434 and the outer peripheral wall of the outer cylinder. This can increase the internal space of the two-component box as much as possible and maintain a safe distance between the two-component box and the outer cylinder 2.

[0094] Specifically, in this embodiment, the two-component box has a first chamber near the housing 1 side and a second chamber near the outer cylinder 2 side. The length of the first chamber in the horizontal direction is greater than the length of the second chamber in the horizontal direction; the first heat exchange part 4451 is arranged in the first chamber, and the second heat exchange part 4452 is arranged in the second chamber.

[0095] In a clothes treatment device with a heat pump drying function according to this embodiment, the outer peripheral wall of the outer cylinder 2 is hoisted in the housing 1 through a damping hanging spring 53. An inwardly concave avoidance structure 4435 is arranged on the side wall surface of the two-component box opposite to the damping hanging spring 53 for avoiding the installation of the damping hanging spring 53. Specifically, the inwardly concave avoidance structure 4435 is an inwardly concave structure formed by partial inward depression of the side wall surface of the two-component box opposite to the damping hanging spring 53.

[0096] In a clothes treatment device with a heat pump drying function according to this embodiment, the heat pump module includes a fan assembly 43. The fan assembly 43 is fixed on the housing 1 and is located above the left or right of the outer cylinder. There is a gap between the fan assembly 43 and the outer peripheral wall of the outer cylinder 2. The two-component assembly is arranged on one side near the opening of the outer cylinder 2, and the fan assembly 43 is arranged on one side near the bottom of the outer cylinder 2. An air outlet 22 is opened at the top of the outer peripheral wall of the outer cylinder. The fan assembly 43 is communicated with the air outlet 22 through an air outlet duct 41; the two-component box has a two-component box air inlet, and the fan air outlet of the fan assembly 43 is directly connected to the two-component box air inlet; a door seal 24 is installed at the opening of the outer cylinder 2. The two-component box has a two-component box air outlet, and the two-component box air outlet is communicated with the door seal 24 through an air inlet duct 511.

[0097] As an alternative implementation of this embodiment, in a clothes treatment device with a heat pump drying function according to this embodiment, there is an outer cylinder avoidance area 231 on the outer peripheral wall of the outer cylinder 2 at a position opposite to the two-component box for avoiding the installation of the two-component box. Specifically, the outer cylinder avoidance area 231 is formed by reducing the height of the reinforcing rib at the position on the outer peripheral wall of the outer cylinder 2 opposite to the two-component box or removing the reinforcing rib, thereby reducing the installation height of the two-component box.

[0098] Example 2

[0099] This embodiment specifically designs the two-chamber box in Embodiment 1 to achieve the installation of the two-component assembly, the optimization of the circulation of the drying air flow, etc.

[0100] See Figures 1 - 3 、 Figures 10 - 13 As shown in the figure, a laundry treatment device with a heat pump drying function according to this embodiment includes:

[0101] An outer drum 2;

[0102] A housing 1, and the outer drum 2 is arranged in the inner space of the housing 1;

[0103] And a heat pump module, including a two-chamber box and a two-component module 445 formed by integrating a condenser 442 and an evaporator 441 in the two-chamber box 447. The two-chamber box 447 has a two-chamber box air inlet 4431, and the two-chamber box air inlet 4431 is inclined relative to the horizontal direction.

[0104] Specifically, the air inlet 4431 forms an acute angle with the horizontal direction; the two-chamber box air inlet 4431 is preferably an approximately rectangular shape with two long sides and two short sides.

[0105] In this embodiment, the inclination direction of the two-chamber box air inlet 4431 is inclined towards the direction of the connection line between the two points farthest from each other on the cross-section of the heat exchange main body of the two-component module 445, or the inclination direction of the two-chamber box air inlet 4431 is consistent with the direction of the connection line between the two points farthest from each other on the upper diagonal of the cross-section of the heat exchange main body of the two-component module 445.

[0106] In this embodiment, the inclination direction of the two-chamber box air inlet 4431 is inclined towards the direction of the connection line between the two points farthest from each other on the cross-section of the heat exchange main body of the two-component module 445, or the inclination direction of the two-chamber box air inlet 4431 is consistent with the direction of the connection line between the two points farthest from each other on the upper diagonal of the cross-section of the heat exchange main body of the two-component module 445. In this way, it ensures the consistency of the flow direction of the humid and hot drying air flow towards the heat exchange main body of the two-component module 445, avoids the cross-flow of the drying air flow flowing from the two-chamber box air inlet 4431 towards the heat exchange main body of the two-component module 445, and improves the drying heat exchange efficiency.

[0107] Further, the two-device box 447 described in this embodiment includes a box peripheral sidewall and a box bottom wall. The box peripheral sidewall and the box bottom wall enclose an open accommodation space for accommodating the two-device module. The box bottom wall is opposite to the outer cylinder 2 and is spaced apart therefrom. The air inlet 4431 of the two-device box is provided on the box peripheral sidewall facing the drying air flow and is close to the box bottom wall. In this embodiment, the principle of hot air rising is utilized, and the air inlet 4431 of the two-device box is arranged at the bottom of the two-device box, enabling the humid and hot drying air flow to rise and come into more sufficient contact with the two-device module 445, thereby improving the drying efficiency.

[0108] Specifically, the two-device box described in this embodiment includes a first box sidewall facing the drying air flow and a second box sidewall opposite to the first box sidewall. The box bottom wall is an inwardly concave arc surface that is concave towards the internal accommodation space of the two-device box. The air inlet 4431 of the two-device box is opened on the first box sidewall and is close to the box bottom wall. The two-device box also has an air outlet of the two-device box opened on the second box sidewall.

[0109] As an alternative implementation manner of this embodiment, the two-device module 445 has a first heat exchange portion 4451 close to the housing side in the vertical direction and a second heat exchange portion 4452 close to the outer cylinder side. The first heat exchange portion 4451 is formed by a first heat exchange tube 4453 with a first length inserted into first fins, and the second heat exchange portion 4452 is formed by a second heat exchange tube 4455 with a second length inserted into second fins. The length of the first heat exchange tube 4453 is greater than the length of the second heat exchange tube 4455. The projection of the air inlet 4431 of the two-device box on the projection plane perpendicular to the central axis of the outer cylinder obliquely crosses the projection of the diagonal line of the two-device module 445 on the projection plane perpendicular to the central axis of the outer cylinder.

[0110] As an alternative implementation manner of this embodiment, the air inlet 4431 of the two-device box is directly opposite to the evaporator heat exchange surface of the two-device module 445, and there is a spacing between the air inlet 4431 of the two-device box and the evaporator heat exchange surface. The range of the spacing is 20 mm to 80 mm. The two-device module 445 is arranged at a certain distance range from the air inlet 4431 of the two-device box, which can reduce the wind resistance, ensure the smooth flow of the drying air flow, and at the same time reduce the load of the fan assembly.

[0111] As an alternative implementation of this embodiment, both the first heat exchange part 4451 and the second heat exchange part 4452 have a heat exchange main body and a heat exchange pipe joint located at one end of the heat exchange main body. A wind guide plate 4433 is arranged on one side of the air inlet 4431 of the two-device box to guide the drying air to flow onto the heat exchange surface main body. When using an avoidance design, the two devices also need to have an avoidance structure accordingly. There are pipelines on both sides of the two devices, so the L-shaped is the best solution, which not only avoids the two-device box but also provides space for the condenser pipe. However, there is a gap in the L-shaped two-device module, and this requires the two-device box to be made into a wind baffle to ensure that the wind can completely pass through the two devices. The wind guide plate 4433 in this embodiment is an L-shaped plate identical to the L-shaped two-device module, which can better divert the drying air flow entering from the air inlet 4431 of the two-device box to the windward heat exchange surface of the two-device module, blocking the drying air flow to the heat exchange pipe joint. The wind resistance of the drying air flow at the heat exchange joint is small, and the heat exchange effect is poor.

[0112] Meanwhile, the heat pump module in this embodiment includes a compressor arranged on the rear housing of the outer cylinder. The compressor is connected to the two-device module 445 through a heat pump medium pipeline. A pipeline channel is formed between the wind guide plate 4433 and the two-device box body 443, and the heat pump medium pipeline passes through the pipeline channel and is connected to the heat exchange pipe joint. The wind guide plate 4433 in this embodiment is also used to construct a pipeline channel for the layout and connection of the heat pump medium pipeline between the compressor and the two-device module.

[0113] See Figure 12 As shown, in order to install the two-device module 445, the specific structure of the two-device box body 443 in this embodiment is as follows: A first support plate 4434 for supporting the first heat exchange part 4451 of the evaporator 441, a second support plate 4437 for the second heat exchange part 4452 of the evaporator 441, a third support plate 44314 for supporting the first heat exchange part 4451 of the condenser 442, a fourth support plate 44310 for the second heat exchange part 4452 of the condenser 442, and a partition card plate for separating the evaporator 441 and the condenser 442 are arranged on the inner wall surface of the box bottom wall. The first support plate 4434 and the second support plate 4437 are both located on one side of the partition card plate, and the third support plate 44314 and the fourth support plate 44310 are both located on the other side of the partition card plate. The first support plate 4434 and the second support plate 4437 in this embodiment realize the support and installation of the evaporator 441, the third support plate 44314 and the fourth support plate 44310 realize the support and installation of the condenser 442, and the partition card plate is inserted between the evaporator 441 and the condenser 442 by means of clamping while separating the integrated evaporator 441 and condenser 442.

[0114] Optionally, a stepped support platform 4436 is further provided on the inner wall surface of the bottom wall of the box. The partition card board includes a first partition card board 4435 and a second partition card board 4439 provided on the stepped support platform 4436. The first heat exchange parts 4451 and the second heat exchange parts 4452 at the mutually close ends of the evaporator 441 and the condenser 442 respectively abut against the stepped support platform 4436. The first partition card board 4435 is inserted and clamped between the first heat exchange part of the evaporator 441 and the first heat exchange part of the condenser 442, and the second partition card board 4439 is inserted and clamped between the second heat exchange part of the evaporator 441 and the second heat exchange part of the condenser 442.

[0115] In addition, on the inner peripheral wall of the two-device box body 443 of this embodiment, two-device corner limit blocks 44311 for circumferentially limiting the installation of the two-device module are provided. The two-device corner limit blocks 44311 abut against the corners of the two-device module for circumferential limitation to prevent circumferential shaking.

[0116] On the two-device box body 443 of this embodiment, two-device box studs 44312 are further provided for realizing the fixed connection and assembly with the two-device box cover 444.

[0117] As an optional implementation manner of this embodiment, a condensate drain joint 44313 for discharging condensate is provided on the bottom wall of the two-device box 447 of this embodiment. The water outlet direction of the condensate drain joint 44313 is consistent with the flow direction of the drying air in the two-device box 447. In this way, the condensate can be discharged by means of the drying air flow, avoiding the problem that the condensate accumulates and reduces the drying efficiency.

[0118] Furthermore, a support plate for supporting the two-device module 445 is provided on the inner bottom wall of the two-device box 447. One end of the support plate close to the condensate drain joint 44313 has a condensate water diversion arc surface 4438 bent towards the condensate drain joint, so that the condensate water of the two-device module 445 can be diverted to the condensate drain joint 44313.

[0119] The structural design of the two-device box 447 of this embodiment has the following beneficial effects:

[0120] 1. By applying the principle that hot air rises, the air inlet of the two-device box is arranged at the bottom of the two-device box body, so that the humid and hot drying air flow rises and contacts the two-device module more fully, improving the drying efficiency.

[0121] 2. In the projection direction on the front of the whole machine, the obliquely arranged air inlet obliquely crosses the diagonal direction of the two-device module, ensuring the consistency of the flow direction of the humid and hot drying air flow and avoiding cross-flow.

[0122] 3. The two-unit module is set at a certain distance range from the air inlet of the two units, which can reduce the wind resistance, ensure the smooth flow of the drying air flow, and at the same time reduce the fan load.

[0123] 4. The water outlet direction of the condensate drain joint is the same as the flowing direction of the drying air flow, which can utilize the wind force to drain the condensate, avoid the accumulation of condensate, and prevent the problem of reduced drying efficiency.

[0124] Example 3

[0125] In this embodiment, specific optimization design is carried out for the assembly and structural improvement of the fan assembly of the heat pump module, which can better utilize the internal space of the housing for assembly, improve the space utilization rate inside the housing, ensure the drying efficiency, and at the same time simplify the installation process. The specific scheme is as follows:

[0126] See Figures 1 - 3 、 Figures 14 - 18 As shown in

[0127] An outer cylinder 2 with an air outlet 22 at the top;

[0128] A housing 1, and the outer cylinder 2 is arranged in the internal space of the housing 1;

[0129] And a heat pump module, including an evaporator, a condenser, a heat exchange air duct and a fan assembly 43 arranged in the space between the upper part of the outer cylinder 2 and the housing 1. The evaporator and the condenser are arranged in the heat exchange air duct. The fan air inlet of the fan assembly 43 is communicated with the air outlet 22 on the outer cylinder 2. The fan air outlet of the fan assembly 43 is directly fixedly connected to the air duct air inlet of the heat exchange air duct, forming an integrated connection structure. The air duct air outlet of the heat exchange air duct is communicated with the inside of the outer cylinder 2.

[0130] The heat pump module described in this embodiment is composed of a two-unit assembly, a heat exchange air duct, a fan assembly 43 and a wind guiding assembly. The two-unit assembly 43 includes a condenser 442 and an evaporator 441, which are respectively used to generate heat and absorb heat, and are both obtained by inserting copper tubes through fins. And the two-unit assembly is connected to the compressor 451 through copper tubes to form a complete two-unit flow path.

[0131] The heat exchange air duct assembly is internally provided with support ribs for placing the two-unit assembly. The two-unit assembly is completely placed in the heat exchange air duct assembly, while ensuring that the ventilation area is not affected, and the movement of the two-unit assembly is restricted by the surrounding ribs and sponge strips, so that the degrees of freedom of the two-unit assembly are completely restricted. At the same time, the heat exchange air duct assembly is connected to the wind guiding assembly 446 and the fan assembly 43, and forms a complete heat pump drying circulating air path through connection with the outer cylinder. At the same time, the heat exchange air duct serves as the channel for the air path circulation.

[0132] The two-heat-exchanger assembly is located between the outer cylinder and the housing. The outer cylinder is a cylindrical structure, and the housing is a planar structure. The spatial structure where the two-heat-exchanger assembly is placed is a space composed of an arc surface and a plane. On the premise of ensuring the overall height of the machine, based on this space, the two-heat-exchanger assembly is set to the maximum to improve the heat pump drying effect.

[0133] At the same time, a safety gap is left between the heat exchange air duct assembly and the outer cylinder. In the effective space between the outer cylinder and the housing, the two-heat-exchanger assembly is set to the maximum to facilitate increasing the fin heat exchange area and improving the drying efficiency.

[0134] Correspondingly, the evaporator in the two-heat-exchanger assembly is located behind the fan assembly. The fan assembly can blow the humid air in the outer cylinder into the evaporator and the condenser, and condense the water in the air after passing through the evaporator. Then, under the action of gravity, it flows along the fins to the bottom of the heat exchange air duct, and the condensed water is discharged through the ribs arranged at the bottom of the heat exchange air duct. And when passing through the condenser, heat is generated by the condenser to convert the cold and dry air flowing through the condenser into hot and dry air, which re-enters the outer cylinder through the first connecting piece.

[0135] The heat pump module is attached to the housing, and the heat pump module is fixed to the housing so that it is not affected by the vibration of the outer cylinder.

[0136] In this embodiment, the fan assembly 43 is fixedly connected to the heat exchange air duct with an evaporator and a condenser arranged inside to form an integrated structure. When the integrated module assembled by the evaporator, the condenser and the fan assembly is integrally installed in the housing 1, it avoids the problems of cumbersome assembly and high assembly precision requirements caused by separately installing the evaporator, the condenser, the heat exchange air duct and the fan assembly 43 in the housing respectively. Moreover, through the installation of the integrated module, the internal installation space required for the housing 1 can be reduced, the utilization rate of the internal space of the housing 1 can be improved, and the overall height of the washing machine can be reduced.

[0137] See Figure 15 As shown, a first buckle structure 431 and a first assembly hole 432 are arranged on the outer periphery of the fan outlet in this embodiment. A second slot structure 44315 and a second assembly hole 44316 are arranged on the outer periphery of the air duct air inlet of the heat exchange air duct. The fan air outlet and the air duct air inlet are pre-fixed by clamping the first buckle structure 431 with the second slot structure 44315, and then the fan air outlet and the air duct air inlet are fixedly connected by passing a connecting piece through the first assembly hole 432 and fastening it in the second assembly hole 44316, so that the evaporator, the condenser, the heat exchange air duct and the fan assembly are assembled into an integrated module.

[0138] In this embodiment, a combination of a buckle and a screw is adopted. The buckle structure is designed for pre-fixing during assembly, and then fastening is carried out by screws.

[0139] Further, in order to improve the sealing performance of the connection between the blower air outlet and the air duct air inlet and prevent air leakage, a sealing ring 46 is provided between the blower air outlet and the air duct air inlet in this embodiment, and an annular sealing groove for assembling the sealing ring is provided in the blower air outlet and / or the air duct air inlet.

[0140] As an alternative implementation of this embodiment, in order to solve the problem of the fixed installation of the blower assembly 43 in the housing, refer to FIG. Figure 15 , 16 and FIG. 18, the blower assembly includes a volute, a blower impeller 4310 and a blower motor 438. The blower impeller 4310 is arranged in the volute, the blower motor 438 is arranged on the volute, the motor shaft of the blower motor 4310 extends into the volute to connect the blower impeller 4310, the blower air inlet is arranged on the volute, the blower air inlet and the blower impeller share the same central axis, the blower air outlet is arranged on the volute, and the central axis of the blower air outlet is perpendicular to the central axis of the blower impeller; the volute is fixedly installed on the housing 1, and the blower assembly 43 is eccentrically arranged in the upper right of the outer cylinder 2. In this embodiment, the blower assembly 43 is fixedly installed on the housing 1. Since the blower assembly, the evaporator 441, the condenser 442, and the heat exchange air duct are assembled into an integrated module, the evaporator 441, the condenser 442, and the heat exchange air duct are also fixedly installed on the housing 1.

[0141] Further, the housing 1 includes a frame assembly 11. The frame assembly includes a rear frame plate 111 and left and right frame plates 113 and 112 that are fixedly arranged at both ends of the rear frame plate 111 and are opposite to each other. The volute is fixedly installed on at least the rear frame plate 111 and the right frame plate 112. In this embodiment, the blower assembly 43 is fixedly installed in at least two directions through the rear frame plate 111 and the right frame plate 112 to ensure the stability of its assembly.

[0142] Specifically, the volute includes an upper volute 434 and a lower volute 4311. The upper volute 434 and the lower volute 4311 are fixedly connected to enclose a volute chamber for arranging the blower impeller 4310. A platform is arranged on the upper volute 434, and a fixing column 435 with a threaded hole inside is arranged on the lower volute 4311. The platform and the fixing column 435 are arranged along the circumference of the volute; the platform is fixedly lapped on the right frame plate 112 / rear frame plate 111, and the fixing column 435 is fixed on the rear frame plate 111 / right frame plate 112 through a connecting piece.

[0143] In this embodiment, a first platform 433 and a second platform 434 are provided on the upper volute 434. The frame assembly includes a corner frame plate 114 that bridges the right frame plate 112 and the rear frame plate 111. The first platform 433 is fixedly lapped on the right frame plate 112, the second platform 434 is fixedly lapped on the corner frame plate 114, and the fixing column 435 is fixed on the rear frame plate 111 through a connecting piece. The corner frame plate 114 of this embodiment not only realizes the fixed installation of the fan assembly 43, making the installation of the fan assembly 43 more stable, but also increases the overall strength of the frame assembly, ensuring the stability of the whole washing machine.

[0144] In this embodiment, multi-directional fixing structures such as platforms and fixing columns are designed on the structure of the fan assembly. Through the analysis of the fixing stability and the stress angle, the multi-directional fixing structures such as platforms and fixing columns need to be arranged within a position range not less than one-third of the diameter of the fan assembly; and they are fixed on the whole machine box through screw fasteners. When the whole machine box vibrates due to outer cylinder washing or dehydration, the multi-directional fixing structures effectively ensure the stability of the fan assembly.

[0145] During the drying process, the fan motor 4310 drives the fan impeller 4310 to rotate at a certain speed. The fan impeller 4310 under high-speed operation drives the internal circulation movement of the drying air flow, so that the air flow is sucked from the outer cylinder 2 into the fan assembly 43, and then flows towards the heat exchange module at a certain speed, forming the air flow movement in the drying air duct.

[0146] The drying process described in this embodiment means that during drying, the fan assembly 43 will operate at a high speed through the fan motor 4310. The air flow in the loop is sucked from the outer cylinder 2 through the air outlet into the fan assembly 43, and then driven by the high-speed fan motor 4310 of the fan assembly 43, it makes a centrifugal movement at a certain speed and enters the heat exchange air duct. Then it enters the outer cylinder 2 again and continues to be sucked into the drying loop by the fan assembly 43, circulating continuously.

[0147] See Figure 18 As shown, the air inlet of the fan in this embodiment is communicated with the air outlet 22 on the outer cylinder body 23 of the outer cylinder 2 through a flexible adapter 41. Since the fan assembly 43 is fixed on the frame assembly 11, the outer cylinder body 23 will vibrate during the operation of the washing machine. Therefore, the connection between the outer cylinder body 23 and the fan assembly 43 is realized through the flexible adapter 41, avoiding damage caused by the interaction between the vibration of the outer cylinder body 23 and the fan assembly 43.

[0148] Furthermore, in this embodiment, the center of the air outlet 22 is set at a position on the central axis plane of the top of the outer cylinder body 23, closer to the rear cylinder part. The flexible adapter 41 has a first connection port connected to the air outlet 22 and a second connection port connected to the air inlet of the fan. There is an eccentric distance between the central axis of the first connection port and the central axis of the second connection port.

[0149] In this embodiment, the first connection port and the air outlet are tightly connected by a first fastening clamp 437, and the second connection port and the air inlet of the fan are tightly connected by a second fastening clamp 436.

[0150] Specifically, this embodiment provides a flexible adapter 41 for a fan assembly, which uses a rubber adapter to connect the drying air duct and the outer cylinder. Utilizing the stretchability and ductility of the rubber adapter, when the outer cylinder vibrates or is pulled by multi-directional forces during washing, dehydration and other program operations, it ensures that the drying air duct is not affected by vibration and maintains a complete and closed circulating air path system.

[0151] The rubber adapter in this embodiment is installed on the top of the outer cylinder to connect the fan assembly and the outer cylinder; the connection position on the top of the outer cylinder is called the air outlet. Among them, the placement method of the fan assembly forms a certain angle (within 90°) with the horizontal plane; the first connecting member 511 is installed at the front position of the outer cylinder to connect the air guiding assembly 446 and the outer cylinder; in this assembly, both the rubber adapter and the first connecting member are flexible structures and materials that can generate a movement stroke.

[0152] Correspondingly, the air outlet is arranged at the top of the outer cylinder to reduce the length of the air path circulation, thereby reducing the resistance of the drying circulating air path and improving the drying efficiency. At the same time, it also plays the role of the circulating air path.

[0153] At the air outlet, a first filter screen 411 needs to be arranged to filter the lint generated during the drying process.

[0154] Example 4

[0155] This embodiment conducts specific optimization design for the assembly and structural improvement of the compressor assembly of the heat pump module, makes better use of the space inside the housing for assembly, improves the space utilization rate inside the housing, ensures the drying efficiency, and simplifies the installation process. The specific scheme is as follows:

[0156] See Figures 1 - 3 、 Figures 19 - 21 As shown, a clothes treatment device with a heat pump drying function in this embodiment includes:

[0157] Outer cylinder 2;

[0158] The frame component 11, with the outer cylinder 2 arranged in the inner space of the frame component 11;

[0159] And a heat pump module, including an evaporator 441, a condenser 442 and a compressor 451. The condenser 442 and the evaporator 441 are integrated to form a two-device module 44. The two-device module 44 is arranged above the outer cylinder 2. The compressor 451 is arranged on the frame component 11, and the compressor 451 is connected to the two-device module 44 through a heat pump medium pipeline.

[0160] In the clothes treatment device of this embodiment, the two-device module 44 is arranged above the outer cylinder 2, and the compressor 451 is arranged on the frame component 11 and behind the outer cylinder 2. The reasonable layout of the positions among the modules reduces the production cost, makes rational use of the internal space of the washing machine, and reduces the overall height of the machine.

[0161] See Figure 20 As shown, the frame component 11 of this embodiment includes a rear frame plate 111 and a left frame plate 113 and a right frame plate 112 that are fixedly arranged at both ends of the rear frame plate 111 and are opposite to each other. The bottom of the left frame plate 113 has a left bottom plate 118, and the bottom of the right frame plate 112 has a right bottom plate 117. The compressor 451 is fixedly installed on a fixed bottom plate 116, and both ends of the fixed bottom plate 116 are respectively fixed at one end of the left bottom plate 118 close to the rear frame plate 111 and one end of the right bottom plate 117 close to the rear frame plate 111.

[0162] In this embodiment, the compressor 451 is fixed on the frame component 11 through the fixed bottom plate 116, reducing the displacement of the compressor caused by vibration during the operation of the compressor 451 and reducing the resonance of the working conditions of the compressor 451, making the whole machine operate smoothly.

[0163] See Figure 21 As shown, the compressor 451 of this embodiment is fixed on the fixed bottom plate 116 through an assembly component. The assembly component includes an assembly bolt 4511 and a fastening nut 458. Assembly through holes are arranged on the fixed bottom plate 116, and fixed feet 459 are arranged on the casing of the compressor 451. The assembly bolt 4511 sequentially passes through the assembly through hole and the fixed foot 459 from bottom to top, and the fastening nut 458 is fastened on one end of the assembly bolt 4511 extending out of the fixed foot 459.

[0164] Furthermore, the assembly component further includes a pre-tightening elastic washer 4510. The pre-tightening elastic washer 4510 is sleeved on the assembly bolt 4511 and is located between the fixed foot 459 and the fixed bottom plate 116.

[0165] Further, an assembly press mold 1161 is provided on the fixed bottom plate 116. The assembly press mold 1161 matches the shape of the end of the casing of the compressor 451. After the compressor 451 is fixedly installed on the fixed bottom plate 116, the end of the casing of the compressor 451 abuts against the inside of the assembly press mold 1161.

[0166] Further, there are multiple assembly through-holes, which are evenly distributed along the outer periphery of the assembly press mold 1161. There are multiple fixing feet 459, which are evenly distributed along the outer periphery of the casing of the compressor 451 and are arranged in one-to-one correspondence with the assembly through-holes.

[0167] During installation, the assembly through-holes and the fixing feet 459 are assembled in one-to-one correspondence. The assembly bolts 4511 sequentially pass through the assembly through-holes on the fixed bottom plate 116, the pre-tightening elastic washers 4510, and the fixing feet 459 from bottom to top, and are locked by the fastening nuts 458 arranged above the fixing feet 459. When the assembly is in place, the bottom of the compressor 451 abuts against the assembly press mold 1161. The pre-tightening elastic washers 4510 provide the pre-tightening force for bolt locking and can absorb a certain amount of vibration energy, thereby reducing the risk of bolt locking failure caused by the vibration generated during the operation of the compressor. The assembly press mold provides locking feedback for the locking of the compressor and forms a certain structural limit in the horizontal direction, improving the locking strength of the compressor.

[0168] See Figure 20 As shown, a cooling fan 453 is provided on the left frame plate and / or the right frame plate of this embodiment. The air outlet direction of the cooling fan 453 faces the compressor 451 for cooling the compressor. See Figure 24 As shown, heat dissipation holes 119 for the heat dissipation air blown out by the cooling fan 453 to flow out of the interior of the housing 1 are provided on the rear frame plate 111.

[0169] The heat pump module of this embodiment further includes a two-device box for setting the two-device module. The two-device box has a two-device box air outlet, and the two-device box air outlet is communicated with the interior of the outer cylinder 2 through an air inlet duct 511.

[0170] Further, the heat pump module of this embodiment includes a fan assembly 43. An air outlet 22 is opened on the outer cylinder 2. The fan assembly 43 is communicated with the air outlet 22 through an air outlet duct 41. The two-device box has a two-device box air inlet, and the two-device box air inlet is communicated with the air outlet of the fan assembly.

[0171] In the laundry treatment device of this embodiment, the two-device module and the fan assembly are eccentrically arranged above the peripheral wall of the outer cylinder. The two-device module is arranged at one end near the mouth of the outer cylinder, and the fan assembly is arranged at one end near the bottom of the outer cylinder.

[0172] The pipeline connection mode between the compressor, evaporator and condenser in this embodiment is as follows:

[0173] See Figures 22 - 25 As shown, the compressor 451 in this embodiment is connected with a first heat pump medium pipeline 455 and a second heat pump medium pipeline 454. The evaporator is connected with a third heat pump medium pipeline 456 detachably connected to the first heat pump medium pipeline 455. The condenser is connected with a fourth heat pump medium pipeline 457 detachably connected to the second heat pump medium pipeline 454.

[0174] The compressor, evaporator and condenser in this embodiment are respectively connected to the heat pump medium pipelines. When the individual components are assembled in the housing, there will be no interference between the components, making assembly easier. After the compressor, evaporator and condenser are respectively assembled, connecting the corresponding heat pump medium pipelines can achieve the connection of the heat pump medium pipelines between the components. Therefore, the separate connection mode of the heat pump pipelines in this embodiment simplifies the assembly sequence between components and reduces production costs.

[0175] As an optional implementation mode of this embodiment, the frame assembly 11 in this embodiment includes a rear frame plate and left and right frame plates 113 and 112 fixedly arranged at both ends of the rear frame plate 111 and opposite to each other. An installation through hole 115 is provided on the rear frame plate 111. The connection positions of the first heat pump medium pipeline 455 and the third heat pump medium pipeline 456, and the connection positions of the second heat pump medium pipeline 454 and the fourth heat pump medium pipeline 457 all correspond to the installation through hole 115. In this way, the installation through hole 115 on the frame assembly 11 is used for pipeline connection and disassembly and maintenance, simplifying the assembly and reducing the production and after-sales maintenance costs.

[0176] As an optional implementation mode of this embodiment, the evaporator and condenser in this embodiment are both relatively fixedly installed on the frame assembly 11 and are located above the outer cylinder 2. The first heat pump medium pipeline 455 and the third heat pump medium pipeline 456, and the second heat pump medium pipeline 454 and the fourth heat pump medium pipeline 457 are all relatively fixedly connected. Since the evaporator and condenser are both relatively fixedly installed on the frame assembly 11, and the compressor is also relatively fixedly installed on the frame assembly 11, there will be no relative displacement between the evaporator, condenser and compressor, and a relatively fixed hard connection mode can be adopted between the heat pump medium pipelines.

[0177] Specifically, the first heat pump medium pipeline 455 and the third heat pump medium pipeline 456 are both rigid pipes, and the first heat pump medium pipeline 455 and the third heat pump medium pipeline 456 are fixedly connected through a first rigid pipe joint; the second heat pump medium pipeline 454 and the fourth heat pump medium pipeline 457 are both rigid pipes, and the second heat pump medium pipeline 454 and the fourth heat pump medium pipeline 457 are fixedly connected through a second rigid pipe joint. Specifically, the first heat pump medium pipeline 455, the third heat pump medium pipeline 456, the second heat pump medium pipeline 454, and the fourth heat pump medium pipeline 457 are all made of copper or aluminum metal pipes, and the first rigid pipe joint and the second rigid pipe joint are made of copper or aluminum pipe joints.

[0178] Meanwhile, the heat pump module described in this embodiment includes a fan assembly 43 and an air outlet duct 41. The fan assembly 43 is internally communicated with the inside of the outer cylinder 2 through the air outlet duct 41 and is used to drive the drying air to flow between the outer cylinder 2, the evaporator, and the condenser; the fan assembly 43 is installed on the frame assembly 11, and the air outlet duct 41 is a flexible deformation duct. Since the fan assembly 43 is fixedly installed on the frame assembly 11, the outer cylinder will vibrate during the operation of the washing machine, so it is necessary to connect through a flexible deformation duct.

[0179] As an alternative implementation of this embodiment, the evaporator and the condenser described in this embodiment are both relatively fixedly installed at the top of the circumferential wall of the outer cylinder 2, and the first heat pump medium pipeline 455 and the third heat pump medium pipeline 456, and the second heat pump medium pipeline 454 and the fourth heat pump medium pipeline 457 are connected through flexible deformation pipes. Since the evaporator and the condenser are both installed on the outer cylinder, and the compressor is relatively fixedly installed on the frame assembly 11, the outer cylinder will vibrate during the operation of the washing machine, so relative displacement will occur between the evaporator, the condenser, and the compressor, and a soft connection method with relative movement is adopted between the heat pump medium pipelines.

[0180] Specifically, the first heat pump medium pipeline and the third heat pump medium pipeline are both rigid pipes, and the flexible deformation pipe includes a first soft rubber pipe. The first heat pump medium pipeline and the third heat pump medium pipeline are connected through the first soft rubber pipe so as to be relatively movable;

[0181] The second heat pump medium pipeline and the fourth heat pump medium pipeline are both rigid pipes, and the flexible deformation pipe includes a second soft rubber pipe. The second heat pump medium pipeline and the fourth heat pump medium pipeline are connected through the second soft rubber pipe so as to be relatively movable.

[0182] Meanwhile, the heat pump module described in this embodiment includes a fan assembly 43. The fan assembly 43 is relatively fixedly installed at the top of the circumferential wall of the outer cylinder 2, and an air outlet 22 is provided at the top of the outer cylinder 2. The air inlet of the fan assembly 43 is directly fixedly connected to the air outlet, or the air inlet of the fan assembly 43 is fixedly connected to the air outlet through an air outlet duct, for driving the drying air to flow between the outer cylinder and the evaporator and the condenser. The fan assembly 43 is fixed on the outer cylinder and moves synchronously with the outer cylinder, and the two are relatively stationary. Therefore, the air path connection method between the fan assembly 43 and the outer cylinder 2 can be a hard connection.

[0183] In this embodiment, the condenser and the evaporator are integrated to form a two-device module. The heat pump module further includes a two-device box for arranging the two-device module. The two-device box has a two-device box air inlet, and the air outlet of the fan assembly is fixedly connected to the two-device box air inlet.

[0184] A door seal is installed at the opening of the outer cylinder described in this embodiment. The two-device box has a two-device box air outlet, and the two-device box air outlet is communicated with the door seal through an air inlet duct.

[0185] In this embodiment, the two-device component and the compressor component of the heat pump module are placed separately in the overall machine position. During the overall machine assembly, the heat pump medium pipelines between the two components are welded respectively, and then connected through the intermediate pipeline A after the two components are assembled in place respectively.

[0186] The following beneficial effects are obtained through this invention:

[0187] (1) The separate placement of the two devices and the compressor reduces the overall height of the machine and realizes the miniaturization of the heat pump type clothing treatment device;

[0188] (2) The compressor is placed behind the cylinder and fixed on the bottom plate, making reasonable use of the internal space of the overall machine;

[0189] (3) The separate welding method of the heat pump pipeline simplifies the assembly sequence between components and reduces the production cost;

[0190] (4) Using the installation through holes on the frame for pipeline connection simplifies the assembly and reduces the production and after-sales maintenance costs.

[0191] The exemplary embodiments of the present disclosure are specifically illustrated and described above. It should be understood that the present disclosure is not limited to the detailed structures, setting methods or implementation methods described here; on the contrary, the present disclosure is intended to cover various modifications and equivalent settings included within the spirit and scope of the appended claims.
