Description

Technical Field

[0001] The present invention relates to the technical field of washing equipment, and in particular to a clothing processing device with a heat pump drying function. Background Art

[0002] There are two main types of washing machines with drying functions on the market: the first is heat pump drying, and the second is electric heating drying. The drying principle of heat pump models is to let the humid air pass through the evaporator first, so that the water vapor in it condenses into liquid and then flows into the drainage system through the two boxes, thereby achieving the purpose of drying the air in the barrel. Then the dried air passes through the condenser to absorb the heat generated by the compressor, forming high-temperature dry gas and then enters the barrel for drying. The cycle is repeated to achieve the effect of drying clothes.

[0003] However, since the two boxes are relatively large and the upper end of the washing machine outer drum is an arc surface, in order to avoid the collision between the shaking washing machine drum and the two boxes during the operation of the washing machine, it is necessary to raise the position of the two boxes to avoid the highest point of the washing machine outer drum. Since the upper surface of the washing machine outer drum is an arc, this causes a waste of space between the lowest point and the highest point. In addition, the outer drum is connected to the frame by a hanging spring, and the position of the hanging spring is exactly where the two boxes are located. In order to avoid interference between the two boxes and the hanging spring, it is also necessary to increase the space occupied by the two boxes. As a result, the existing heat pump drying type washing machines are either too high or too wide, and the internal space is seriously wasted.

[0004] Therefore, the present invention aims to solve the following technical problems existing in the existing clothes processing device with heat pump drying function:

[0005] 1. Solve the problem of wasting vertical space caused by the two boxes to avoid the outer drum of the washing machine;

[0006] 2. Solve the problem of lateral space waste caused by the two boxes to avoid the hanging springs;

[0007] 3. The problem of air conduction in the two boxes in the avoidance structure;

[0008] 4. The problem of condensation drainage in the two device boxes in the avoidance structure.

[0061] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0064] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0065] To further illustrate the technical solution of the present invention, Figure 1-Figure 25 , the following specific embodiments are provided.

[0066] See also Figure 1 and Figure 2As shown, the present embodiment provides a clothing processing 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 clothing processing devices with a heat pump drying function. Specifically, the present invention is explained by taking a drum washing machine with a heat pump drying function as an example, but can also be applied to a heat pump drum dryer by those skilled in the art.

[0067] The present embodiment provides a clothing processing device with a heat pump drying function, including a shell 1, in which a coaxially mounted inner drum 3 and an outer drum 2 are arranged, and the outer drum 2 is installed in the shell 1 through a vibration reduction module; the inner drum 3 is driven by a driving motor and is rotatably arranged in the outer drum 2.

[0068] During the washing process of the clothes processing device, washing water enters the outer drum 2 through the water inlet pipe. The water inlet stops when the set water level is reached. The inner drum 3 is driven by the driving motor to rotate in the outer drum 2. During the rotation of the inner drum 2, the clothes are washed by lifting and beating the clothes.

[0069] like Figure 1 As shown, the clothes processing device is placed vertically on a horizontal ground, a panel assembly 8 is arranged in front of the housing 1 of the clothes processing device, a loading port is opened on the panel assembly 8, and a door assembly 9 is installed on the loading port of the panel assembly 8 for opening / closing the loading port. Figure 1 The direction identification in the figure provides examples for the direction limitations of up, down, front, back, left and right involved in the present invention, so as to better explain the technical solution of the present invention.

[0070] Furthermore, the clothes treatment device of this embodiment has a drying function, and the heat pump drying method is realized by the heat pump system. In view of the working efficiency of the heat pump, the existing clothes treatment device generally needs to reserve enough space in the shell to install the heat pump system, which will cause the shell to increase.

[0071] Therefore, the present invention proposes a clothing treatment device with a heat pump drying function, wherein the heat pump system includes an evaporator, a condenser, a compressor and a fan assembly, wherein the fan assembly transports the hot and humid drying air in the outer drum to the evaporator, wherein the evaporator exchanges heat with the hot and humid drying air to condense the moisture in the hot and humid drying air into dry and cold drying air, wherein the dry and cold drying air is transported to the condenser for heat exchange heating to become dry and hot drying air, wherein the dry and hot drying air is introduced into the outer drum for drying clothes and becomes hot and humid drying air again, and then circulated again. The refrigerant as the working medium of the heat pump system circulates among the condenser, the throttling device, the evaporator and the compressor, wherein the refrigerant absorbs heat in the evaporator to cool and dehumidify the hot and humid drying air drawn out of the outer drum, and releases heat in the condenser to heat the dry and cold drying air drawn out from the evaporator.

[0072] The present invention aims to propose a clothing processing device with a heat pump drying function. Taking into account the internal space layout of a shell of the clothing processing device, the internal space of the shell is fully utilized to realize the setting of a heat pump system, ensure the drying efficiency and drying effect, and keep the shell of the clothing processing device with a heat pump drying function the same size as the shell of an ordinary corresponding kilogram-class clothing processing device.

[0073] Embodiment 1

[0074] This embodiment designs the structure and installs the layout of the evaporator and the condenser, thereby ensuring that the evaporator and the condenser can be installed in the space inside the shell, improving the space utilization inside the shell, and effectively controlling the height of the whole machine. The specific technical solution is as follows:

[0075] See also Figure 1-Figure 9 As shown, a clothes processing device with a heat pump drying function in this embodiment includes:

[0076] A housing 1 forming an inner space;

[0077] An outer cylinder 2 is arranged in the inner space of the shell 1;

[0078] The heat pump module includes two-device components, which include an evaporator 441 and a condenser 442. The evaporator 441 and / or the condenser 442 are arranged in the upper left space or the upper right space of the inner and outer cylinders 2 of the shell 1. The heat exchange body of the evaporator 441 and / or the condenser 442 has an external contour adapted to the upper left space or the upper right space where it is located.

[0079] This embodiment is aimed at the structural characteristics of the upper left space or the upper right space in the shell of the clothing treatment device. Specifically, for a drum washing machine, a detergent dispensing device is generally required to be arranged in the upper left space, while there is a certain amount of free space in the upper right space opposite to the upper left space. Therefore, the clothing treatment device of this embodiment arranges the two device components in the upper left space or the upper right space of the inner and outer drums 2 of the shell 1 according to the characteristics of the internal space of the shell. Further, since the upper left space or the upper right space of the inner and outer drums 2 of the shell 1 is limited, and in order to ensure that the height size of the whole machine of the clothing treatment device remains unchanged, 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 device components as much as possible. Therefore, the heat exchange body of the evaporator 441 and / or the condenser 442 of this embodiment has an external 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 has an external contour adapted to the upper left space or the upper right space where it is located, which means that the heat exchange body adopts an irregular layout mode, but is adapted to the installation space to ensure the drying efficiency.

[0080] As an optional implementation of this embodiment, the cross section of the heat exchange body of the evaporator 441 and / or condenser 442 described in this embodiment perpendicular to the axis of the outer cylinder is wide at the top and narrow at the bottom. This is because the outer cylinder 2 is a cylindrical structure, the shell 1 is a rectangular parallelepiped structure, and the upper left space or the upper right space between the shell 1 and the outer cylinder 2 is wide at the top and narrow at the bottom. In order to make full use of the space, the heat exchange body of the evaporator 441 and / or condenser 442 is adapted to be wide at the top and narrow at the bottom.

[0081] As an optional implementation of this embodiment, the cross-section is approximately in the shape of a step surface or approximately inverted L shape. In this way, not only can the installation space in the shell 1 be fully utilized, but also the processing and manufacturing of the evaporator 441 and / or the condenser 442 is facilitated.

[0082] In this embodiment, the evaporator 441 and the condenser 442 are arranged in the upper left or upper right space of the inner and outer tubs 2 of the shell 1 in combination with the spatial layout in the shell 1, mainly considering the arrangement of the structural components in the shell 1. Specifically, a detergent dispensing box is generally arranged in the upper left of the inner and outer tubs 2 of the shell 1 of the existing clothing processing device, so the evaporator 441 and the condenser 442 can be arranged in the upper right space of the inner and outer tubs 2 of the shell 1; if the detergent dispensing box is considered to be arranged in the upper right of the inner and outer tubs 2 of the shell 1, then the evaporator 441 and the condenser 442 can be arranged in the upper left space of the inner and outer tubs 2 of the shell 1.

[0083] The evaporator 441 and condenser 442 of this embodiment are arranged in a limited space inside the shell 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 fully utilizing the space inside the shell 1 and cannot meet the drying efficiency.

[0084] Therefore, the shape of the heat exchange body of the evaporator 441 and / or condenser 442 of this embodiment is adapted to the space between the shell 1 and the outer cylinder 2. That is to say, the overall structure of the evaporator 441 and / or condenser 442 is adaptively designed according to the installation space and is no longer a regular rectangle. This can not only make full use of the installation space in the shell, but also ensure the heat exchange efficiency.

[0085] As an optional implementation of this embodiment, the heat exchange body of the evaporator 441 and / or condenser 442 described in this embodiment has a first horizontal side close to the top wall of the shell 1 and a second horizontal side away from the top wall of the shell 1, as well as a first vertical side close to the side wall of the shell 1 on the side and a second vertical side away from the side wall of the shell 1 on the 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 shell, the space of the upper left or upper right part of the inner and outer cylinders 2 of the shell 1 gradually decreases in horizontal length from top to bottom in the vertical direction. Therefore, in order to adapt to the installation space, the heat exchange body of the evaporator 441 and / or condenser 442 of this embodiment has a horizontal distance of the first horizontal side close to the outer cylinder 2 shorter than the horizontal distance of the second horizontal side away from the outer cylinder 2.

[0086] In order to facilitate the assembly of the condenser and the evaporator, as an optional implementation of this embodiment, see Figure 5 As shown, the condenser 442 and the evaporator 441 described in this embodiment are integrated into a two-device module 44, and the heat exchange body of the condenser 442 and the evaporator 441 includes a first heat exchange part 4421 and a second heat exchange part 4421, both of which have different lengths in the horizontal direction, so that the heat exchange body of the two-device module 44 presents a stepped surface with a horizontal length away from the outer cylinder side greater than the horizontal length close to the outer cylinder side. In order to better utilize 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 the space, the cross-sectional shape of the heat exchange body of the two-device module 44 is set to an "L" shape, a "7" shape, etc., and is placed in the space to maximize the cross-sectional area of ​​the heat exchange body of the two-device module 44, so as to improve the heat pump drying effect.

[0087] See also Figure 5 As 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] As an optional implementation of this embodiment, the outer wall surface of the two container boxes on one side opposite to the outer cylinder peripheral wall is an inner concave arc surface 4434, the inner concave arc surface 4434 and the outer cylinder peripheral wall share a central axis, and there is a gap between the inner concave arc surface 4434 and the outer cylinder peripheral wall. In this way, the internal space of the two container boxes can be increased as much as possible, and a safe distance between the two container boxes and the outer cylinder 2 can be maintained.

[0092] Specifically, the two-device box described in this embodiment has a first chamber for the side near the shell body 1 and a second chamber for the side near the outer tube 2, and 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.

[0097] This embodiment carries out a specific structural design for the two-device box in the first embodiment, so as to realize the installation of the two-device components, optimize the circulation of the drying airflow, etc.

[0098] See also Figure 1-Figure 3 , Figure 10-13 As shown, a clothes processing device with a heat pump drying function in this embodiment includes:

[0099] outer cylinder 2;

[0100] The shell 1, the outer cylinder 2 is arranged in the inner space of the shell 1;

[0101] And a heat pump module, including two device boxes and a two-device module 445 which is arranged in the two-device box 447 and is integrated with a condenser 442 and an evaporator 441. The two-device box 447 has a two-device box air inlet 4431, and the two-device box air inlet 4431 is inclined relative to the horizontal direction.

[0102] Specifically, the air inlet 4431 forms an acute angle with the horizontal direction; the air inlet 4431 of the two device boxes is preferably in an approximately rectangular shape with two upper and lower long sides and two left and right short sides.

[0103] The inclination direction of the air inlets 4431 of the two device boxes is inclined toward the direction of the line between the two points on the windward heat exchange surface close to the two device modules 445 that are farthest apart, or the inclination direction of the air inlets 4431 of the two device boxes is consistent with the direction of the line between the two points on the windward heat exchange surface close to the two device modules 445 that are farthest apart.

[0104] The tilt direction of the air inlet 4431 of the two-device box in this embodiment is tilted toward the direction of the line connecting the two points on the windward heat exchange surface that are farthest from each other and close to the two-device module 445. In this way, the angle between the tilt direction of the air inlet 4431 of the two-device box and the direction of the line connecting the two points on the windward heat exchange surface that are farthest from each other is as small as possible, ensuring the consistency of the flow direction of the humid and hot drying airflow toward the windward heat exchange surface of the two-device module 445, avoiding the cross-flow of the drying airflow flowing from the air inlet 4431 of the two-device box toward the windward heat exchange surface of the two-device module 445, and improving the drying heat exchange efficiency.

[0105] Optionally, the inclination direction of the air inlet 4431 of the two device boxes is consistent with the direction of the line connecting the two points on the windward heat exchange surface of the two device modules 445 that are farthest apart, so that the angle between the inclination direction of the air inlet 4431 of the two device boxes and the direction of the line connecting the two points on the windward heat exchange surface that are farthest apart is 0. In this way, the air inlet 4431 of the two device boxes can completely cover the entire windward heat exchange surface of the two device modules 445, ensuring that the humid and hot drying airflow is all directed toward the windward heat exchange surface of the two device modules 445, thereby maximizing the drying heat exchange efficiency.

[0106] Furthermore, the two-device box 447 described in this embodiment includes a box peripheral side wall and a box bottom wall, the box peripheral side wall 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 arranged at a distance, and the two-device box air inlet 4431 is arranged on the box peripheral side wall facing the drying airflow and close to the box bottom wall. This embodiment uses the principle of hot air rising, and sets the two-device box air inlet 4431 at the bottom of the two-device box so that the hot and humid drying airflow rises and contacts the two-device module 445 more fully, thereby improving the drying efficiency.

[0107] Specifically, the two container boxes described in this embodiment include a first box side wall facing the drying airflow and a second box side wall opposite to the first box side wall, and the box bottom wall is a concave arc surface concave toward the internal accommodating space of the two container boxes; the two container box air inlets 4431 are opened on the first box side wall and close to the box bottom wall, and the two container boxes also have two container box air outlets opened on the second box side wall.

[0108] As an optional implementation scheme of this embodiment, the two-device module 445 has a first heat exchange part 4451 close to the shell side in the vertical direction and a second heat exchange part 4452 close to the outer tube side, 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; the projection of the two-device box air inlet 4431 on the projection plane perpendicular to the center axis obliquely crosses the projection of the diagonal of the two-device module 445 on the projection plane perpendicular to the center axis.

[0109] As an optional implementation of this embodiment, the two-device box air inlet 4431 is directly opposite to the evaporator heat exchange surface of the two-device module 445, and there is a spacing between the two-device box air inlet 4431 and the evaporator heat exchange surface, and the range of the spacing is 20mm to 80mm. The two-device module 445 and the two-device box air inlet 4431 are set at a certain distance range, which can reduce wind resistance, ensure the smooth flow of drying airflow, and reduce the load of the fan component.

[0110] As an optional implementation of this embodiment, the first heat exchange part 4451 and the second heat exchange part 4452 both have a heat exchange body and a heat exchange pipe joint at one end of the heat exchange body, and a wind guide plate 4433 for guiding the drying airflow to the heat exchange surface body is arranged on one side of the air inlet 4431 of the two-device box in the two-device box. When the avoidance design is adopted, the two devices also need to make an avoidance structure accordingly. There are pipelines on both sides of the two devices, so the L-shape is the best solution, which not only avoids the two-device box but also provides space for the condenser pipe, but there is a gap in the L-shaped two-device module, which requires the two-device box to be used as a windshield to ensure that the wind can completely pass through the two devices. The wind guide plate 4433 of this embodiment is the same L-shaped plate as the L-shaped two-device module, which can better guide the drying airflow entering the air inlet 4431 of the two-device box to the windward heat exchange surface of the two-device module, blocking the drying airflow from the heat exchange pipe joint, and the wind resistance of the drying airflow at the heat exchange joint is small, and the heat exchange effect is poor.

[0111] At the same time, the heat pump module described in this embodiment includes a compressor arranged on the shell behind 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 air 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 air guide plate 4433 of this embodiment is also used to construct a pipeline channel for arranging and connecting the heat pump medium pipeline between the compressor and the two-device module.

[0112] See also Fig.12As shown, in order to realize the installation of the two-device module 445, the two-device box body 443 of this embodiment has a specific structure as follows: a first support plate 4434 for supporting the first heat exchange part 4451 of the evaporator 441 and a second support plate 4437 for supporting the second heat exchange part 4452 of the evaporator 441 are arranged on the inner wall surface of the bottom wall of the box, a third support plate 44314 for supporting the first heat exchange part 4451 of the condenser 442 and a fourth support plate 44310 for supporting the second heat exchange part 4452 of the condenser 442, and a partition card plate for separating the evaporator 441 and the condenser 442, the first support plate 4434 and the second support plate 4437 are located on one side of the partition card plate, and the third support plate 44314 and the fourth support plate 44310 are located on the other side of the partition card plate.

[0113] Optionally, a stepped support platform 4436 is also provided on the inner wall surface of the bottom wall of the box, and the partition card includes a first partition card plate 4435 and a second partition card plate 4439 provided on the stepped support platform 4436, and the first heat exchange part 4451 and the second heat exchange part 4452 of the evaporator 441 and the condenser 442 close to each other at one end are respectively abutted on the stepped support platform 4436, and the first partition card plate 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 plate 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.

[0114] In addition, the inner circumferential wall of the two-device box body 443 of this embodiment is provided with two-device corner limit blocks 44311 for circumferentially limiting the installation of the two-device modules. The two-device corner limit blocks 44311 abut against the corners of the two-device modules for circumferential limitation to prevent circumferential shaking.

[0115] In this embodiment, two device box studs 44312 are also provided on the two device box bodies 443 to achieve fixed connection and assembly with the two device box covers 444.

[0116] As an optional implementation of this embodiment, the bottom wall of the two-container box 447 of this embodiment is provided with a condensed water drainage joint 44313 for draining condensed water, and the water outlet direction of the condensed water drainage joint 44313 is consistent with the flow direction of the drying air in the two-container box 447. In this way, the condensed water can be drained with the help of the drying air force, avoiding the problem of condensed water accumulation and reducing the drying efficiency.

[0117] Furthermore, a support plate for supporting the two-device module 445 is provided on the bottom inner wall of the two-device box 447, and the end of the support plate close to the condensate drain joint 44313 has a condensate guide arc surface 4438 bent toward the condensate drain joint, so that the condensate of the two-device module 445 can be drained to the condensate drain joint 44313.

[0118] The structural design of the two-device box 447 of this embodiment has the following beneficial effects:

[0119] 1. Using the principle of hot air rising, the air inlet of the two-device box is set at the bottom of the two-device box body to make the hot and humid drying air flow rise and contact the two-device module more fully, thereby improving the drying efficiency.

[0120] 2. In the projection direction of the front of the whole machine, the tilted air inlet is set diagonally across the two modules to ensure the consistency of the flow direction of the hot and humid drying airflow and avoid cross-flow.

[0121] 3. The two modules are set at a certain distance from the air inlets of the two devices, which can reduce wind resistance, ensure smooth flow of drying airflow, and reduce fan load.

[0122] 4. The water outlet direction of the condensate drainage joint is consistent with the flow direction of the drying airflow. The condensate can be discharged with the help of wind force to avoid the accumulation of condensate and the reduction of drying efficiency.

[0123] Embodiment 3

[0124] This embodiment makes specific optimization design for the assembly and structural improvement of the fan assembly of the heat pump module, makes better use of the space inside the shell for assembly, improves the space utilization rate inside the shell, ensures the drying efficiency, and simplifies the installation process. The specific scheme is as follows:

[0125] See also Figure 1-Figure 3 , Figure 14-18 As shown, this embodiment provides a clothes processing device with a heat pump drying function, comprising:

[0126] The outer cylinder 2 has an outer cylinder air outlet 22 at the top;

[0127] The shell 1, the outer cylinder 2 is arranged in the inner space of the shell 1;

[0128] 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 outer cylinder 2 and the shell 1, the evaporator and the condenser are arranged in the heat exchange air duct, the fan air inlet of the fan assembly 43 is connected with the outer cylinder air outlet 22 on the outer cylinder 2, the fan air outlet of the fan assembly 43 is directly fixedly connected with the air duct inlet of the heat exchange air duct to form an integrated connection structure, and the air duct outlet of the heat exchange air duct is connected to the inside of the outer cylinder 2.

[0129] The heat pump module described in this embodiment is composed of two-device components, a heat exchange air duct, a fan component and an air guide component; the two-device components include a condenser and an evaporator, which are used to generate heat and absorb heat respectively, both of which are obtained by copper tubes inserted through fins; and the two-device components are connected to the compressor through copper tubes to form a complete two-device flow path.

[0130] The heat exchange duct assembly is provided with supporting ribs for placing the two device assemblies, and the two device assemblies are completely placed in the heat exchange duct assembly, while ensuring that the ventilation area is not affected, and the movement of the two device assemblies is limited by the surrounding ribs and sponge strips, so that the freedom of the two device assemblies is completely restricted; at the same time, the heat exchange duct assembly is connected to the air guide assembly 446 and the fan assembly 43, and through the connecting outer cylinder, a complete heat pump drying circulation air circuit is formed; at the same time, the heat exchange duct serves as a channel for air circulation.

[0131] The two-device components are located between the outer cylinder and the shell, and the outer cylinder is a cylindrical structure, the shell is a flat structure, and the space structure where the two-device components are placed is a space composed of an arc surface and a plane. On the premise of ensuring the height of the whole machine, the two-device components are set to the maximum based on this space to enhance the heat pump drying effect.

[0132] At the same time, a safety gap is left between the heat exchange air duct component and the outer cylinder, and the two components are arranged to the maximum extent within the effective space between the outer cylinder and the shell, so as to increase the heat exchange area of ​​the fins and improve the drying efficiency.

[0133] Correspondingly, the evaporator of the two-device assembly is located after the fan assembly, and the fan assembly can blow the hot and humid air in the outer cylinder into the evaporator and the condenser, and condense the water in the air after passing through the evaporator, and flow to the bottom of the heat exchange air duct along the fins under the action of gravity, and discharge the condensed water through the ribs arranged at the bottom of the heat exchange air duct; and when passing through the condenser, heat is generated through the condenser, so that the cold and dry air flowing through the condenser is converted into hot and dry air, and re-enters the outer cylinder through the first connecting member;

[0134] The heat pump module is attached to the shell, and the heat pump module is fixed on the shell so that it is not affected by the vibration of the outer cylinder.

[0135] The fan assembly 43 of this embodiment is fixedly connected to the heat exchange air duct with the evaporator and condenser installed inside to form an integrated structure. When the integrated module assembled by the evaporator, condenser and fan assembly is installed in the housing 1 as a whole, the evaporator, condenser, heat exchange air duct and fan assembly 43 are installed separately in the housing, which causes the assembly to be cumbersome and requires high assembly precision. Moreover, the integrated module installation can reduce the internal installation space of the housing 1, improve the internal space utilization of the housing 1, and reduce the height of the machine.

[0136] See also Fig.15 As shown, the periphery of the fan outlet described in this embodiment is provided with a first snap structure 431 and a first assembly hole 432, and the periphery of the air duct inlet of the heat exchange air duct is provided with a second slot structure 44315 and a second assembly hole 44316. The fan outlet and the air duct inlet are pre-fixed by snapping the first snap structure 431 and the second slot structure 44315, and then the fan outlet and the air duct inlet are fixedly connected by a connecting piece passing through the first assembly hole 432 and fastened to the second assembly hole 44316, so that the evaporator, condenser, heat exchange air duct and fan assembly are assembled into an integrated module.

[0137] In this embodiment, the buckle structure is designed by combining buckles and screws to facilitate pre-fixation during assembly, and then fastened by screws.

[0138] Furthermore, in order to improve the sealing of the connection between the fan outlet and the air duct inlet and prevent air leakage, a sealing ring 46 is arranged between the fan outlet and the air duct inlet in this embodiment, and an annular sealing groove for assembling the sealing ring is arranged in the fan outlet and / or the air duct inlet.

[0139] As an optional implementation of this embodiment, in order to solve the problem of fixed installation of the fan assembly 43 in the housing, see FIG. Fig.15 , 16 As shown in Figure 18, the fan assembly includes a volute, a fan impeller 4310 and a fan motor 438. The fan impeller 4310 is arranged in the volute, and the fan motor 438 is arranged on the volute. The motor shaft of the fan motor 4310 extends into the volute to connect with the fan impeller 4310. The fan air inlet is arranged on the volute, and the fan air inlet and the fan impeller share the same central axis. The fan air outlet is arranged on the volute, and the central axis of the fan air outlet is arranged perpendicular to the central axis of the fan impeller; the volute is fixedly mounted on the housing 1, and the fan assembly 43 is eccentrically arranged at the upper right of the outer cylinder 2. In this embodiment, the fan assembly 43 is fixedly mounted on the housing 1. Since the fan assembly, the evaporator, the condenser, and the heat exchange air duct are assembled as an integrated module, the evaporator, the condenser, and the heat exchange air duct are also fixedly mounted on the housing 1.

[0140] Furthermore, the shell 1 includes a frame assembly 11, which includes a rear frame plate 111 and a left frame plate 113 and a right frame plate 112 fixed at both ends of the rear frame plate 111 and arranged opposite to each other. The volute is at least fixedly mounted on the rear frame plate 111 and the right frame plate 112. In this embodiment, the fan assembly 43 is fixedly mounted in at least two directions through the rear frame plate 111 and the right frame plate 112 to ensure the stability of its assembly.

[0141] 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 in which the fan impeller 4310 is arranged. 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 overlapped on the right frame plate 112 / rear frame plate 111, and the fixing column 435 is fixed to the rear frame plate 111 / right frame plate 112 through a connecting piece.

[0142] The upper volute 434 of this embodiment is provided with a first platform 433 and a second platform 434, the frame assembly includes an angle frame plate 114 spanning the right frame plate 112 and the rear frame plate 111, the first platform 433 is fixedly overlapped on the right frame plate 112, the second platform 434 is fixedly overlapped on the angle frame plate 114, and the fixing column 435 is fixed on the rear frame plate 111 through a connecting piece. The angle 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 machine.

[0143] In this embodiment, a multi-directional fixing structure such as a platform and a fixing column is designed on the structure of the fan assembly. Through the analysis of fixing stability and force angle, the multi-directional fixing structure such as the platform and the fixing column needs to be arranged in a position range not less than one-third of the diameter of the fan assembly; and fixed to the whole machine housing by screw fasteners. When the outer drum washing or dehydration causes the whole machine housing to vibrate, the multi-directional fixing structure effectively ensures the stability of the fan assembly.

[0144] During the drying process, the fan motor 4310 drives the fan impeller 4310 to rotate at a certain speed. The fan impeller 4310 running at a high speed drives the internal circulation movement of the drying airflow, so that the airflow is sucked into the fan assembly 43 from the outer cylinder 2, and then flows to the heat exchange module at a certain speed, forming an airflow flow in the drying air duct.

[0145] The drying process described in this embodiment means that during drying, the fan assembly 43 will rotate at high speed through the fan motor 4310, and the air flow in the circuit will be sucked into the fan assembly 43 through the outer tube air outlet in the outer tube 2, and then driven by the high-speed fan motor 4310 of the fan assembly 43, it will move centrifugally at a certain speed and enter the heat exchange air duct. Then it will enter the outer tube 2 again and continue to be sucked into the drying circuit by the fan assembly 43, and the cycle will continue.

[0146] See also Fig.18 As shown, the fan air inlet of this embodiment is connected with the outer drum air outlet 22 on the outer drum body 23 of the outer drum 2 through a flexible adapter 41. Since the fan assembly 43 is fixed on the frame assembly 11, the outer drum body 23 will vibrate during the operation of the washing machine. Therefore, the outer drum body 23 is connected to the fan assembly 43 through the flexible adapter 41 to avoid damage caused by the interaction force between the vibration of the outer drum body 23 and the fan assembly 43.

[0147] Furthermore, in this embodiment, the center of the air outlet 22 is set on the rear cylinder position on the top central axis surface of the outer cylinder body 23, and the flexible adapter 41 has a first connection port connected to the outer cylinder air outlet 22 and a second connection port connected to the fan air inlet, and there is an eccentric distance between the central axis of the first connection port and the central axis of the second connection port.

[0148] In this embodiment, the first connection port is fastened to the air outlet of the outer cylinder via a first fastening clamp 437 , and the second connection port is fastened to the air inlet of the fan via a second fastening clamp 436 .

[0149] Specifically, the present embodiment provides a flexible adapter 41 of a fan assembly that uses a rubber adapter to connect the drying duct and the outer drum, utilizing the stretchability and ductility of the rubber adapter. When the outer drum is vibrating or subjected to multi-directional force during washing, dehydration and other procedures, the drying duct is not affected by vibration and a complete closed circulation air duct system is maintained.

[0150] The rubber adapter described in this embodiment is installed at the top of the outer cylinder to connect the fan assembly and the outer cylinder; the connection position at the top of the outer cylinder is called the outer cylinder air outlet, wherein the fan assembly is placed in a manner to form a certain angle (within 90°) with the horizontal plane; the first connecting member 511 is installed in the front position of the outer cylinder to connect the air guide assembly 446 and the outer cylinder; in this assembly, the rubber adapter and the first connecting member are both flexible structures and materials that can generate a motion stroke.

[0151] Correspondingly, the outer drum air outlet is arranged at the top of the outer drum so as to reduce the length of the air circulation path, thereby reducing the resistance of the drying circulation air path, improving the drying efficiency, and also playing the role of the circulation air path.

[0152] The outer cylinder air outlet needs to be provided with a first filter 411 at the outer cylinder air outlet to filter the hair debris generated during the drying process.

[0159] The clothing processing device of this embodiment arranges the two-device module 44 above the outer drum 2, and the compressor 451 is arranged on the frame assembly 11 and located behind the outer drum 2. The reasonable position layout between the modules reduces the production cost, reasonably utilizes the internal space of the shell, and reduces the height of the whole machine.

[0160] See also Fig. 20 As shown, the frame assembly 11 described in this embodiment includes a rear frame plate 111 and a left frame plate 113 and a right frame plate 112 fixed at both ends of the rear frame plate 111 and arranged 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 mounted on the fixed bottom plate 116, and the two ends of the fixed bottom plate 116 are respectively fixed to 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.

[0161] In this embodiment, the compressor 451 is fixed to the frame assembly 11 by fixing the bottom plate 116, so as to reduce the displacement of the compressor 451 caused by vibration during the operation of the compressor 451, reduce the working resonance of the compressor 451, and make the whole machine run smoothly.

[0162] See also Fig.21 As shown, the compressor 451 described in this embodiment is fixed on the fixed base plate 116 through an assembly component; the assembly component includes an assembly bolt 4511 and a fastening nut 458, an assembly through hole is set on the fixed base plate 116, and a fixing foot 459 is set on the casing of the compressor 451, the assembly bolt 4511 passes through the assembly through hole and the fixing foot 459 from bottom to top in sequence, and the fastening nut 458 is fastened to the end of the assembly bolt 4511 extending out of the fixing foot 459.

[0172] See also Figure 22-25 As shown, the compressor 451 described in this embodiment is connected to a first heat pump medium pipeline 455 and a second heat pump medium pipeline 454, the evaporator is connected to a third heat pump medium pipeline 456 that is detachably connected to the first heat pump medium pipeline 455, and the condenser is connected to a fourth heat pump medium pipeline 457 that is detachably connected to the second heat pump medium pipeline 454.

[0173] The compressor, evaporator, and condenser of this embodiment are connected to the heat pump medium pipelines respectively. When the individual components are assembled in the shell, there is no interference between the components, which makes it easier to assemble. After the compressor, evaporator, and condenser are assembled respectively, the corresponding heat pump medium pipelines are connected to achieve the heat pump medium pipeline connection between the components. Therefore, the separate connection method of the heat pump pipelines of this embodiment simplifies the assembly sequence between the components and reduces the production cost.

[0174] As an optional implementation of this embodiment, the frame assembly 11 described in this embodiment includes a rear frame plate and a left frame plate 113 and a right frame plate 112 fixed at both ends of the rear frame plate 111 and arranged opposite to each other; the rear frame plate 111 is provided with a mounting through hole 115, and the connection position of the first heat pump medium pipeline 455 and the third heat pump medium pipeline 456, and the connection position of the second heat pump medium pipeline 454 and the fourth heat pump medium pipeline 457 correspond to the mounting through hole 115. In this way, the mounting through holes 115 on the frame assembly 11 are used for pipeline connection and disassembly and maintenance, which simplifies assembly and reduces production and after-sales maintenance costs.

[0175] As an optional implementation of this embodiment, the evaporator and condenser described in this embodiment are fixedly mounted on the frame assembly 11 and are located above the outer tube 2; the first heat pump medium pipeline 455 and the third heat pump medium pipeline 456, the second heat pump medium pipeline 454 and the fourth heat pump medium pipeline 457 are relatively fixedly connected. Since the evaporator and the condenser are fixedly mounted on the frame assembly 11, and the compressor is also fixedly mounted on the frame assembly 11, there will be no relative displacement between the evaporator, the condenser and the compressor, and the heat pump medium pipelines can be relatively fixedly connected.

[0176] Specifically, the first heat pump medium pipeline 455 and the third heat pump medium pipeline 456 are both hard pipes, and the first heat pump medium pipeline 455 and the third heat pump medium pipeline 456 are fixedly connected by a first hard pipe joint; the second heat pump medium pipeline 454 and the fourth heat pump medium pipeline 457 are both hard pipes, and the second heat pump medium pipeline 454 and the fourth heat pump medium pipeline 457 are fixedly connected by a second hard 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 hard pipe joint and the second hard pipe joint are made of copper or aluminum pipe joints.

[0177] At the same time, the heat pump module described in this embodiment includes a fan assembly 43 and an air outlet duct 41. The fan assembly 43 is connected to the inside of the outer drum 2 through the air outlet duct 41, and is used to drive the drying air to circulate between the outer drum 2 and the evaporator and 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 drum will vibrate during the operation of the washing machine, so it needs to be connected through the flexible deformation duct.

[0178] As an optional implementation of this embodiment, the evaporator and condenser described in this embodiment are fixedly mounted on the top of the outer drum 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 by flexible deformation tubes. Since the evaporator and the condenser are both mounted on the outer drum, and the compressor is fixedly mounted on the frame assembly 11, the outer drum will vibrate during the operation of the washing machine, so relative displacement will occur between the evaporator, the condenser and the compressor, and the heat pump medium pipelines are connected by a relative motion soft connection method.

[0179] Specifically, the first heat pump medium pipeline and the third heat pump medium pipeline are both hard pipes, and the flexible deformation pipe includes a first flexible rubber pipe, and the first heat pump medium pipeline and the third heat pump medium pipeline are connected by the first flexible rubber pipe so as to be relatively movable;

[0180] The second heat pump medium pipeline and the fourth heat pump medium pipeline are both hard pipes, and the flexible deformation pipe includes a second flexible rubber pipe. The second heat pump medium pipeline and the fourth heat pump medium pipeline can be connected in relative motion through the second flexible rubber pipe.

[0181] At the same time, the heat pump module described in this embodiment includes a fan assembly 43, which is fixedly mounted on the top of the outer tube 2, and the outer tube air outlet 22 is opened at the top of the outer tube 2; the air inlet of the fan assembly 43 is directly fixedly connected to the outer tube air outlet 22, or the air inlet of the fan assembly 43 is fixedly connected to the outer tube air outlet 22 through the air outlet duct, which is used to drive the drying air to circulate between the outer tube and the evaporator and condenser. The fan assembly 43 is fixed on the outer tube and moves synchronously with the outer tube, and the two are relatively stationary, so the air path connection between the fan assembly 43 and the outer tube 2 can be a hard connection.

[0182] The condenser and evaporator described in this embodiment are integrated into a two-device module, and the heat pump module also includes a two-device box for setting the two-device module. The two-device box has two-device box air inlets, and the air outlet of the fan assembly is fixedly connected to the two-device box air inlets.

[0183] In this embodiment, a door seal is installed at the tube mouth of the outer tube, and the two device boxes have two device box air outlets, and the two device box air outlets are connected to the door seal through air inlet ducts.

[0184] In this embodiment, the two device components of the heat pump module and the compressor component are placed separately in the whole machine position. When the whole machine is assembled, the heat pump medium pipelines between the two components are welded separately, and then connected through the intermediate pipeline A after the two components are assembled in place.

[0185] The following beneficial effects are achieved through the invention:

[0186] (1) The two devices and the press are placed separately, which reduces the height of the whole machine and realizes the miniaturization of the heat pump type clothes processing device;

[0187] (2) The compressor is placed behind the cylinder and fixed on the bottom plate, making reasonable use of the internal space of the whole machine;

[0188] (3) The separate welding method of heat pump pipelines simplifies the assembly sequence between parts and reduces production costs;

[0189] (4) The mounting holes on the frame are used for pipe connection, which simplifies assembly and reduces production and after-sales maintenance costs.
