The heat pump module of the heat pump washer-dryer mainly includes a fan, a drying air duct, and an evaporator and condenser installed in the drying air duct.

[0004] Under the action of the fan, the airflow circulates between the drying duct and the washing drum. When the airflow passes through the evaporator, the water vapor carried by the airflow is condensed, and the airflow is heated when it passes through the condenser. The existing heat pump module is also equipped with an electric heating component for auxiliary heating in the drying duct. In order to improve the heating efficiency of the electric heating component, the electric heating component is spread throughout the duct, which forms a large obstruction to the airflow, thereby affecting the drying efficiency of the washer-dryer.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] Specifically, Figure 1 and Figure 2 As shown, the heat pump washer-dryer of the present invention comprises a housing 1 and a drum module 2 and a heat pump module 3 arranged in the housing 1. The heat pump module 3 can supply hot air to the drum module 2 to dry the clothes.

[0050] like Figures 2 to 4 As shown, the heat pump module 3 of the utility model includes a drying air duct and a fan 32, wherein the drying air duct includes a first drying air duct 31 and a second drying air duct 33, the first drying air duct 31, the fan 32 and the second drying air duct 33 are connected in sequence, an evaporator 34 is arranged in the first drying air duct 31, a condenser 35 is arranged in the second drying air duct 33, and the drum module 2 is provided with a first air outlet (not shown in the figure) connected to the first drying air duct 31 and a second air outlet (not shown in the figure) connected to the second drying air duct 33.

[0051] In the present embodiment, the hot and humid air in the drum module 2 circulates under the action of the fan 32, enters the first drying duct 31, the second drying duct 33, and the second air outlet into the drum module 2 in sequence, and under the action of the evaporator 34, the moisture in the hot and humid air is condensed and separated from the airflow, and under the action of the condenser 35, the temperature of the air is increased to supply hot air to the drum module 2, thereby drying the clothes in the drum module 2 and further drying the clothes.

[0052] It should be noted that the drying air duct of the present invention is not limited to the two-stage structure described above. Those skilled in the art can also set the drying air duct as a whole-stage structure in actual application. In this case, the fan can be installed on the first air outlet or the second air outlet, and then the fan is connected to the second air outlet or the first air outlet through the drying air duct. Of course, the present invention preferably sets the drying air duct as the first drying air duct and the second drying air duct described above, and the fan is set between the first drying air duct and the second drying air duct.

[0053] Preferably, if Figure 1 and Figure 2 As shown, the first drying air duct 31 , the fan 32 and the second drying air duct 33 are all arranged above the drum module 2 .

[0054] Furthermore, if Figures 2 to 4 As shown, the first drying air duct 31 includes a return air duct 311 and a first heat exchange air duct 312 which are connected. The return air duct 311 and the first heat exchange air duct 312 are arranged at the upper rear of the barrel module 2, that is, close to the rear end of the barrel module 2. The evaporator 34 is arranged in the first heat exchange air duct 312. The first air outlet is arranged at the upper rear of the barrel module 2, that is, the first air outlet is also arranged close to the rear end of the barrel module 2, so as to facilitate the return air duct 311 to be connected with the first air outlet. The first heat exchange air duct 312 extends in the horizontal direction, and the extension direction of the first heat exchange air duct 312 is perpendicular to the axial direction of the barrel module 2.

[0055] The return air duct 311 and the first heat exchange air duct 312 are preferably configured to be detachably fixedly connected.

[0056] Furthermore, if Figures 2 to 4As shown, the second drying air duct 33 includes a second heat exchange air duct 331 and an air outlet duct 332 that are connected. The air outlet duct 332 and the second heat exchange air duct 331 are arranged at the upper left or upper right of the barrel module 2. The condenser 35 is arranged in the second heat exchange air duct 331. The second air outlet is arranged at the upper front of the barrel module 2, that is, the second air outlet is arranged near the front end of the barrel module 2, and the air outlet duct 332 is connected to the second air outlet. The second heat exchange air duct 331 also extends in the horizontal direction, and the extension direction of the second heat exchange air duct 331 is parallel to the axial direction of the barrel module 2, that is, the extension direction of the second heat exchange air duct 331 is perpendicular to the extension direction of the first heat exchange air duct 312, and the two heat exchange air ducts are arranged in an approximately L shape.

[0057] The second heat exchange air duct 331 and the air outlet air duct 332 are preferably configured to be detachably fixedly connected.

[0058] This embodiment is aimed at the structural characteristics of the space above the drum module 2 in the box body 1. Specifically, taking a drum-type heat pump washer-dryer as an example, a clothes treatment agent delivery box generally needs to be set in the front space of the upper left, and accordingly, there is a certain amount of free space in the upper back and upper right. Therefore, the heat pump washer-dryer of this embodiment sets the first drying air duct 31 in the upper back space, the second drying air duct 33 in the upper right, and the fan 32 between the first drying air duct 31 and the second drying air duct 33, located at the upper right corner, according to the characteristics of the internal space of the box body 1. From the perspective of the overall layout, the first drying air duct 31, the fan 32, and the second drying air duct 33 are vertically distributed as a whole, which can maximize the use of free space and ensure that the height of the heat pump washer-dryer remains unchanged.

[0059] It should be noted that the front end of the drum module 2 has a clothing access opening, and those skilled in the art may regard the clothing access opening as a second air outlet, even if the air outlet duct 332 is connected to the clothing access opening, or may also be as follows: Figure 2 As shown, a separate air outlet is opened on the upper front of the barrel module 2 as the second air outlet. Such adjustments and changes to the specific setting form of the second air outlet do not deviate from the principle and scope of the present utility model and should be limited within the protection scope of the present utility model.

[0060] Furthermore, in order to improve the heat exchange efficiency as much as possible within a limited space and ensure the drying effect, it is necessary to increase the heat exchange body of the evaporator 34 and the condenser 35 as much as possible. Therefore, the first heat exchange duct 312 and the second heat exchange duct 331 have an external contour adapted to the space in which they are located, so that the heat exchange body of the evaporator 34 accommodated in the first heat exchange duct 312 and the heat exchange body of the condenser 35 accommodated in the second heat exchange duct 331 can be increased as much as possible.

[0061] Specifically, Figure 2and Figure 3 As shown, the first heat exchange duct 312 is arranged at the upper rear of the barrel module 2, approximately in the middle of the barrel module 2, and because the barrel module 2 is a cylindrical structure, it is approximately in a plane at the middle of the cylindrical structure. Therefore, the first heat exchange duct 312 is approximately a rectangular structure, that is, the first heat exchange duct 312 is approximately flat, and its cross-section is approximately rectangular. Correspondingly, the heat exchange body of the evaporator 34 inside it is arranged in a regular rectangular shape. The second heat exchange duct 331 is arranged at the upper right of the barrel module 2. In order to adapt to the cylindrical structure of the barrel module 2 and make full use of this part of the space, the second heat exchange duct 331 is set to a non-rectangular structure, that is, in this part of the space, the second heat exchange duct 331 is set to a "7"-shaped structure, that is, a structure that is wide at the top and narrow at the bottom, and the surface of the second heat exchange duct 331 close to the barrel module 2 is set to an inner concave arc surface, and the inner concave arc surface is coaxial with the barrel module 2. Correspondingly, as shown in Fig.11 As shown, the heat exchange body of the condenser 35 inside is also arranged in a "7" shape, that is, a structure that is wide at the top and narrow at the bottom.

[0062] It should be noted that the shapes of the first heat exchange duct 312 and the second heat exchange duct 331 described above and the arrangement shapes of the heat exchange bodies corresponding to the evaporators 34 and condensers 35 respectively arranged therein are only exemplary. Those skilled in the art may also make arrangements in other shapes according to actual conditions. As long as the space between the box body 1 and the barrel module 2 can be fully utilized, the bottom contour of the first heat exchange duct 312 and the second heat exchange duct 331 can match the barrel wall contour of the barrel module 2, and the heat exchange body inside the heat exchange duct can maximize the heat exchange efficiency, the present invention does not impose any restrictions on this.

[0063] Preferably, if Fig.10 As shown, the heat pump module 3 of the present invention further includes an electric heating component 37 disposed in the drying air duct, and a gap is left between the electric heating component 37 and the inner wall of the drying air duct.

[0064] By leaving a gap between the electric heating component 37 and the inner wall of the drying air duct, the obstruction to the airflow can be reduced, which is conducive to the smooth flow of the airflow, thereby improving the drying efficiency.

[0065] Exemplarily, the electric heating component 37 is arranged in the second drying air duct 33, specifically, in the second heat exchange air duct 331 of the second drying air duct 33, the electric heating component 37 has a rectangular structure, and the second heat exchange air duct 331 has a non-rectangular structure, specifically a structure that is wide at the top and narrow at the bottom. The second heat exchange air duct 331 includes an upper part and a lower part, the upper part has a rectangular structure, and the lower part is approximately a trapezoidal structure. The electric heating component 37 is arranged close to the upper part of the second heat exchange air duct 331, and the lower part of the second heat exchange air duct 331 is the gap left for the electric heating component 37, which is conducive to the smooth flow of airflow.

[0066] The electric heating component 37 mainly plays a role of auxiliary heating, and a PTC heating component is preferably used.

[0067] Preferably, if Fig.10 As shown, an electric heating element 37 is provided downstream of the condenser 35 .

[0068] Furthermore, the fan 32 is arranged at the upper right corner. In order to make full use of this part of the space, the fan 32 is arranged vertically, and the central axis of the air intake port of the fan 32 (that is, the axis of the impeller of the fan 32) extends horizontally along the transverse direction of the box body 1, that is, perpendicular to the axial direction of the barrel module 2, and the central axis of the air outlet of the fan 32 (the central axis of the air outlet of the fan 32 is perpendicular to the axis of the impeller of the fan 32) extends horizontally along the longitudinal direction of the box body 1, that is, parallel to the axial direction of the barrel module 2. In other words, the extension direction of the central axis of the air intake port of the fan 32 The extension direction of the central axis of the exhaust port of the fan 32 is the same as the extension direction of the first heat exchange air duct 312, and the extension direction of the second heat exchange air duct 331 is the same. The first drying air duct 31 is connected to the air intake port of the fan 32, and the second drying air duct 33 is connected to the exhaust port of the fan 32. In this way, the first drying air duct 31 and the second drying air duct 33 are relatively vertically distributed with the fan 32 as the center, which can maximize the use of the free space between the box body 1 and the drum module 2, so as to further ensure that the overall height size of the heat pump washer-dryer remains unchanged.

[0069] In addition, the return air duct 311 and the outlet air duct 332 are also arranged in a manner that can fully utilize the space between the box body 1 and the cylinder module 2. Specifically, Figure 1 and Figure 2 As shown, the return air duct 311 and the outlet air duct 332 are both configured as bent structures, and the surface close to the barrel module 2 is configured as an inner concave arc surface, which is compatible with the barrel wall surface of the barrel module 2. Among them, the return air duct 311 and the outlet air duct 332 are preferably made of flexible materials, such as rubber tubes.

[0070] Furthermore, the return air duct 311, the first heat exchange air duct 312, the fan 32, the second heat exchange air duct 331 and the air outlet duct 332 are all spaced apart from the barrel wall of the barrel module 2 to ensure a safe distance from the barrel module 2, thereby ensuring their respective normal operation.

[0071] Preferably, if Figures 2 to 4As shown, the first drying air duct 31 of the utility model further includes a first connecting air duct 313, a first end of the first connecting air duct 313 is connected to the first heat exchange air duct 312, and a second end of the first connecting air duct 313 is connected to the air suction port of the fan 32. The caliber of the first connecting air duct 313 gradually narrows from the first end of the first connecting air duct 313 to the second end of the first connecting air duct 313, so that the air can be gathered to the air suction port of the fan 32.

[0072] The extension direction of the first connecting air duct 313 is consistent with the extension direction of the first heat exchange air duct 312. It should be noted that the first connecting air duct 313 and the first heat exchange air duct 312 can be fixedly connected, or can also be integrally arranged.

[0073] Preferably, if Figures 2 to 4 As shown, the second drying air duct 33 of the utility model further includes a second connecting air duct 333, a first end of the second connecting air duct 333 is connected to the exhaust port of the fan 32, and a second end of the second connecting air duct 333 is connected to the second heat exchange air duct 331. The caliber of the second connecting air duct 333 gradually widens from the first end of the second connecting air duct 333 to the second end of the second connecting air duct 333, so that the air flowing out of the exhaust port of the fan 32 can diffuse into the second heat exchange air duct 331.

[0074] The extension direction of the second connecting air duct 333 is consistent with the extension direction of the second heat exchange air duct 331. It should be noted that the second connecting air duct 333 and the second heat exchange air duct 331 can be fixedly connected, or can also be integrally arranged.

[0075] Preferably, if Figure 4 and Fig. 9 As shown, the heat pump module 3 of the present invention further includes a wind shielding structure 3311 arranged in the drying air duct, and the wind shielding structure 3311 is located between the inner wall of the drying air duct and the condenser 35 .

[0076] By setting a wind shield structure 3311 between the inner wall of the drying air duct and the condenser 35, the wind shield structure 3311 extends from the inner wall of the drying air duct to the condenser 35, which can block the airflow from flowing through the gap between the condenser 35 and the inner wall of the drying air duct, so that the airflow can all pass through the condenser 35 and exchange heat with the condenser, thereby improving the drying efficiency.

[0077] Specifically, the wind shielding structure 3311 is arranged in the second drying air duct 33, between the inner wall of the second drying air duct 33 and the condenser 35. More specifically, the wind shielding structure 3311 is arranged in the second heat exchange air duct 331, between the inner wall of the second heat exchange air duct 331 and the condenser 35.

[0078] It should be noted that the utility model does not limit the specific structural form of the windshield structure 3311. For example, the windshield structure can be set as a windshield plate, windshield ribs or windshield protrusions, etc.

[0079] Preferably, if Figure 4 and Fig. 9 As shown, the wind shield structure 3311 of the present invention includes a plurality of wind shields, and the plurality of wind shields are distributed at intervals along the flow direction of the airflow.

[0080] Exemplarily, the number of wind shields is 5, and the 5 wind shields are distributed at intervals along the length direction of the second heat exchange air duct.

[0081] It should be noted that the number of windshields is not limited to the above five, for example, it can also be set to 2, 4 or 6, etc.

[0082] Preferably, if Figure 4 and Fig. 9 As shown, the wind shield is arranged around the condenser 35.

[0083] In order to make it easier to see the internal structure of the second heat exchange air duct 331 and the second connecting air duct 333, the top structure of the second heat exchange air duct 331 and the second connecting air duct 333 is omitted in the figure. Wind shields are provided on the inner bottom, inner top wall and two inner side walls of the second heat exchange air duct. In other words, the wind shields are arranged around the condenser, which has a better wind shielding effect and is conducive to further improving the drying efficiency.

[0084] Preferably, if Figure 4 and Fig. 9 As shown, the wind shield is provided with a stepped support portion 33111 at the portion located below the condenser 35 .

[0085] The wind shield located below the condenser 35 is supported on the bottom of the condenser 35. In order to adapt to the shape of the cylinder module 2, the condenser 35 is configured to have a structure that is wide at the top and narrow at the bottom. The bottom of the condenser 35 is stepped. By providing a stepped support portion 33111 on the portion of the wind shield located below the condenser 35, it can match the shape of the condenser 35, thereby achieving a better wind shielding effect and providing more stable support for the condenser 35.

[0086] Preferably, if Figure 2 As shown, the heat pump module 3 of the present invention further includes a compressor 36 , which is disposed below the cartridge module 2 .

[0087] Exemplarily, the compressor 36 is vertically arranged at the lower left of the barrel module 2. Of course, the compressor 36 can also be horizontally arranged as long as it can be installed in the lower space between the barrel module 2 and the box body 1. The compressor 36, the evaporator 34 and the condenser 35 are connected to each other to form a refrigerant circulation loop. The refrigerant exchanges heat with the hot and humid air flowing through the evaporator 34, which can condense the moisture in the hot and humid air and separate it from the airflow. The refrigerant exchanges heat with the air flowing through the condenser 35, which can increase the temperature of the air, thereby supplying hot air to the barrel module 2.

[0088] The above-mentioned implementation manner and various extended embodiments, by designing the distribution layout of the heat pump module 3 in the heat pump washer-dryer, can ensure that the free space is utilized to the maximum extent while the height of the whole machine remains unchanged, and at the same time, the heat exchange efficiency is improved as much as possible within the limited space to ensure the drying effect. In addition, the various components in the heat pump module 3 are connected in a detachable fixed manner, especially the evaporator 34 and the condenser 35 are designed in a split type, which is conducive to individual replacement and saves costs compared with the existing heat pump module 3 that adopts a modular setting.

[0089] Preferably, if Figure 4 As shown, the first drying air duct 31 of the utility model is provided with a fresh air inlet 3122 , and the fresh air inlet 3122 is located between the evaporator 34 and the fan 32 .

[0090] By setting a fresh air inlet 3122 on the first drying air duct 31, external dry fresh air can be introduced during the drying process, which is beneficial to improving the drying efficiency. In addition, by setting the fresh air inlet 3122 between the evaporator 34 and the fan 32, more fresh air can be introduced, and the temperature of the incoming fresh air will not be affected by the temperature of the evaporator 34, which is more beneficial to improving the drying efficiency.

[0091] For example, Figure 4 As shown, the fresh air inlet 3122 is disposed on the first connecting air duct 313. Of course, those skilled in the art may also dispose the fresh air inlet 3122 on the first heat exchange air duct 312.

[0092] Preferably, if Figure 4 As shown, a fresh air outlet 3321 is provided on the second drying air duct 33 , and the fresh air outlet 3321 is located downstream of the condenser 35 .

[0093] After washing the clothes, if the user does not take out the clothes in time, the fan 32 can be started, and the compressor 36 can not be started, so that the airflow circulates in the drum module 2 and the drying air duct, and the fresh air continuously enters from the fresh air inlet 3122, and part of the airflow will be discharged from the fresh air outlet 3321 to avoid the danger of excessive air pressure in the drum module 2. In addition, by setting the fresh air outlet 3321 downstream of the condenser 35, the wind resistance can be reduced and the assembly is easy.

[0095] By setting an exhaust duct connected to the fresh air outlet 3321, the humid air exhausted from the fresh air outlet 3321 can be directly guided to the outside of the box 1 to avoid excessive humidity inside the box 1. In addition, when there is no need to exhaust air through the fresh air outlet 3321, the electric control valve is in a closed state.

[0099] Among them, the clothing treatment agent delivery box is used to deliver clothing treatment agents (such as detergents, softeners, etc.). During the drying process, due to the entry of fresh air, the pressure in the drum module 2 gradually increases. Under the action of this pressure, the water in the water seal pipe section gradually moves toward the second end of the pressure relief pipe until the water is discharged from the pressure relief pipe. The airflow in the drum module 2 enters the clothing treatment delivery box along the pressure relief pipe, and is discharged to the outside of the casing 1 through the clothing treatment agent delivery box to achieve pressure relief.

[0101] During the drying process, the pressure in the drum module 2 is detected by the pressure sensor. When the pressure in the drum module 2 exceeds a set upper limit, the drainage pump is started to release the pressure.

[0102] It should be noted that the pressure sensor can be communicatively connected to the controller of the heat pump washer-dryer, and the data detected by the pressure sensor is transmitted to the controller, which performs calculations and analysis. When the pressure in the drum module 2 exceeds the set upper limit value, the controller controls the drain pump to start pressure relief.

[0104] The filter device 4 is used to filter the air flow in the first drying air duct 31 and intercept impurities such as lint carried by the air flow. By setting plug interfaces on the box body 1 and the first drying air duct 31, when the filter device 4 needs to be cleaned, the filter component can be pulled out from the first drying air duct 31 and the box body 1. In addition, by setting the first bracket 41 and the second bracket 42 to be detachably connected, after the first bracket 41 is pulled out, the first bracket 41 and the second bracket 42 are disassembled, and then the second bracket 42 is pulled out, which can reduce the required disassembly space and facilitate user disassembly. It is also convenient to clean the filter on the second bracket 42. In addition, by making the two ends of the shell 43 connected to the first plug interface 3121 and the second plug interface 11 respectively, when installing the filter component, it is convenient to smoothly insert the filter component into the first drying air duct 31, and the user experience is better.

[0105] For example, Figures 1 to 3 As shown, the first plug interface 3121 is arranged on the side wall of the front panel of the first heat exchange duct 312 facing the box body 1, and the second plug interface 11 is arranged on the front panel of the box body 1.
