[0032] When a dishwasher is working, it first rinses the dishes with water and then dries them. In related technologies, a fan is used to provide airflow into the dishwasher's inner drum to accelerate the drying process and improve the drying efficiency. However, the vibration generated by the fan during operation can cause frictional vibrations and low-frequency resonance noise, affecting user experience.

[0033] Please see Figures 1 to 4 The present invention provides a heat pump drying device 10, which includes a heat exchange assembly 12 and a base 14. The heat exchange assembly 12 includes a heat exchange shell 16, a heat exchanger 18, and a fan 20. The heat exchange shell 16 includes a first shell 22, and the heat exchanger 18 is located inside the first shell 22. The first shell 22 has a first opening 24. The base 14 includes side plates 26 and a bottom plate 28 that are connected to each other.

[0034] The first housing 22 is fixedly connected to the base plate 28, the side plate 26 closes the first opening 24, and the fan 20 is installed on the side plate 26 and located in the installation space enclosed by the first housing 22 and the side plate 26.

[0035] In the aforementioned heat pump drying device 10, the fan 20 is fixedly connected to the side plate 26 of the base 14, and the first housing 22 is fixedly connected to the bottom plate 28 of the base 14. This can, to a certain extent, prevent the fan 20 from vibrating and causing the heat exchange housing 16 to resonate, thereby avoiding affecting the airtightness of the heat exchange housing 16. At the same time, it can reduce the noise generated by the fan 20 driving the heat exchange housing 16 to vibrate.

[0036] Specifically, the heat pump drying device 10 can dry and heat the gas flowing through it, and guide the gas to a target location for drying. The heat pump drying device 10 includes a heat exchange assembly 12 and a base 14. The heat exchange assembly 12 includes a heat exchange shell 16, a heat exchanger 18, and a fan 20.

[0037] The heat exchanger 18 includes an evaporator. When the heat pump drying device 10 is operating, the evaporator can cool the air by absorbing heat from the air around it, thereby lowering the temperature of the surrounding air and causing the gas flowing through the evaporator to condense into condensate, thus achieving the effect of drying the air.

[0038] The heat exchanger 18 includes a condenser. When the heat pump drying device 10 is working, the condenser can generate heat, thereby absorbing heat from the surrounding air to raise the temperature of the surrounding air, so as to heat the gas flowing through the condenser. The heated gas is then guided to the target location to achieve the effect of drying the target location.

[0039] Fan 20 is used to power the gas flow. Fan 20 is located downstream of the condenser. When fan 20 is started, it can create a negative pressure on the side facing the condenser, thereby drawing in air from around the condenser to enable gas flow.

[0040] The heat exchanger 18 and the fan 20, located in the heat exchange duct formed by the heat exchange shell 16 and the base 14, can better guide the airflow to the target position. However, the fan 20 will generate vibration during operation. If the fan 20 comes into contact with the heat exchange shell 16, it will cause the heat exchange shell 16 to resonate, which may affect the sealing performance of the heat exchange shell 16 and generate noise.

[0041] The fan 20 of the heat pump drying device 10 is fixedly connected to the side plate 26 of the base 14, and the first housing 22 is fixedly connected to the bottom plate 28 of the base 14. The side plate 26 and the first housing 22 form an installation space for the fan 20, which can allow the fan 20 to be located inside the first housing 22, while avoiding resonance with the first housing 22.

[0042] The side plate 26 closes the first opening 24, which can ensure that the installation space formed by the first housing 22 and the side plate 26 has a certain degree of sealing, and can prevent the gas after drying and heating from leaking from the first opening 24 to a certain extent.

[0043] The side plate 26 is connected to the base plate 28, allowing the first housing 22 to be mounted on the base plate 28 while the side plate 26 closes the first opening 24. Optionally, in one embodiment, the side plate 26 and the base plate 28 are connected by welding. Optionally, in one embodiment, the side plate 26 and the base plate 28 are integrally formed sheet metal parts. In this way, the base 14 can have high structural strength while being easy to manufacture and form.

[0044] Please see Figure 1 and Figure 3 In some embodiments, the heat exchange housing 16 includes a second housing 30, a side plate 26 and a first housing 22 forming a second opening 32, the second housing 30 being connected to the first housing 22 and the side plate 26 respectively and covering the second opening 32 to form a heat exchange duct.

[0045] Thus, a relatively closed heat exchange duct is formed between the first shell 22, the second shell 30, and the base 14, which is beneficial for drying, heating, and guiding the gas.

[0046] Specifically, the first housing 22 is mounted on the base plate 28 of the base 14, the side plate 26 closes the first opening 24, the first housing 22 and the side plate 26 form the second opening 32, the second housing 30 is connected to the first housing 22 and the side plate 26 and covers the second opening 32. In this way, a relatively closed heat exchange duct can be formed, and the heat exchanger 18 and the fan 20 are both housed in the heat exchange duct, which is conducive to the drying, heating and guiding of the gas.

[0047] The first housing 22 is fixedly connected to the base plate 28, and the fan 20 is installed on the side plate 26, thereby mitigating the impact of fan 20 vibration on the first housing 22. The second housing 30 is fixedly connected to the side plate 26 and the first housing 22. The first housing 22, the side plate 26, and the second housing 30 support and fix each other, making the connection more reliable in terms of temperature.

[0048] Please see Figure 1 and Figure 2 In some embodiments, the side plate 26 is formed with a horizontally folded fixing part 34, the fixing part 34 is provided with a first mounting hole, the second housing 30 is provided with a second mounting hole, and the heat pump drying device 10 includes a first fastener 40, the first fastener 40 passes through the first mounting hole and the second mounting hole, and is fixedly connected to the second housing 30 and the side plate 26.

[0049] Thus, the fixing part 34 provides an installation position, making the connection between the second housing 30 and the side plate 26 stable and reliable.

[0050] Specifically, the second housing 30 is mounted vertically on the side plate 26, and the side plate 26 forms a horizontally folded fixing part 34. This increases the contact area and installation position between the second housing 30 and the side plate 26, making the connection between the second housing 30 and the side plate 26 more stable and reliable.

[0051] The fixing part 34 has a first mounting hole, the second housing 30 has a second mounting hole, and the first fastener 40 passes through the first mounting hole and the second mounting hole to fix the fixing part 34 and the second housing 30 together.

[0052] During installation, the first and second mounting holes are aligned to achieve precise positioning, and the first fastener 40 is inserted to complete the connection, making the connection convenient, quick, stable and reliable.

[0053] The first housing 22, heat exchanger 18, and fan 20 are respectively mounted on the base 14. The side plate 26 of the base 14 and the first housing 22 form a second opening 32. The second housing 30 covers the second opening 32, forming a relatively closed heat exchange duct between the first housing 22, the second housing 30, and the interior of the base 14. Fasteners are used to connect the components, making the second housing 30 removable. In case of a malfunction of the heat exchanger 18 or the fan 20, the second housing 30 can be disassembled, exposing the fan 20 and the heat exchanger 18 through the second opening 32 for easy maintenance.

[0054] Optionally, in one embodiment, the second housing 30 is connected to the first housing 22 by fasteners, which makes the connection convenient, quick, stable and reliable.

[0055] Optionally, in one embodiment, the fastener includes a screw that provides a strong tightening force to tightly connect the fixing part 34 and the second housing 30 together, effectively preventing relative displacement or loosening between the fixing part 34 and the second housing 30, ensuring that the housing maintains a stable structure during use and can withstand certain external forces and vibrations without easily separating.

[0056] Optionally, in one embodiment, the fastener includes a vibration-damping screw. The vibration-damping screw can absorb and dissipate vibration energy. When the housing is subjected to external vibration or impact, the vibration-damping screw can reduce the transmission of vibration between the fixing part 34 and the second housing 30, thereby reducing the overall vibration amplitude of the housing and reducing noise caused by vibration. Simultaneously, in a vibrating environment, ordinary screw connections may gradually loosen due to vibration, affecting the stability of the connection. The vibration-damping characteristics of the vibration-damping screw can reduce loosening caused by vibration, ensuring that the fixing part 34 and the second housing 30 always remain tightly connected, maintaining the normal operation of the equipment.

[0057] Please see Figure 2In some embodiments, the heat pump drying device 10 includes a vibration damper 42, which is sleeved on at least a portion of the surface of the fan 20 such that the vibration damper 42 is at least partially located between the fan 20 and the side plate 26.

[0058] Thus, the vibration damping component 42 is positioned between the fan 20 and the side plate 26, providing a vibration damping effect.

[0059] Specifically, the vibration damping element 42 is sleeved on at least a portion of the surface of the fan 20, such that when the fan 20 is installed on the side plate 26, the vibration damping element 42 is at least partially located between the fan 20 and the side plate 26, and vibration transmitted from the fan 20 to the side plate 26 must pass through the vibration damping element 42. The vibration damping element 42 can absorb vibration energy, convert the mechanical energy of the vibration into other forms of energy such as heat energy and dissipate it, thereby significantly reducing the vibration energy transmitted to the side plate 26, effectively blocking the vibration transmission path, and thus reducing the overall vibration and noise of the heat pump drying device 10.

[0060] Furthermore, due to reduced vibration transmission, the relative displacement and friction between the fan 20 and the side plate 26 caused by vibration are significantly reduced. Without the damping element 42, long-term vibration would cause continuous friction between the fan 20 and the side plate 26, potentially leading to surface wear, coating peeling, and even affecting the installation stability of the fan 20. The presence of the damping element 42 buffers the forces between the two, protecting the structural integrity of the fan 20 and the side plate 26, reducing potential failures caused by wear, and extending the service life of the fan 20.

[0061] Optionally, the vibration damper 42 may include a rubber vibration damper 42, a silicone vibration damper 42, or a composite material vibration damping pad.

[0062] Please see Figure 3 and Figure 4 In some embodiments, the first housing 22 is provided with a partition plate 41 to separate a first cavity 44 and a second cavity 46. The fan 20 includes an air inlet 53. The fan 20 is housed in the first cavity 44, and the heat exchanger 18 is housed in the second cavity 46. The partition plate 41 is provided with a through hole 52, and the second cavity 46 is connected to the air inlet 53 of the fan 20 through the through hole 52.

[0063] Thus, the fan 20 is installed in the first cavity 44 of the heat exchange housing 16, and the heat exchanger 18 is housed in the second cavity 46, which can prevent the condensate generated when the heat exchanger 18 dries the air from entering the fan 20 and affecting the drying effect.

[0064] Specifically, during the operation of the heat pump drying device 10, the heat exchanger 18 dries the air, causing water vapor in the air to condense upon cooling. Since the heat exchanger 18 is located in the second chamber 46, the condensate accumulates in the second chamber 46 and is discharged through the drainage structure.

[0065] The partition plate 41 separates the first cavity 44 and the second cavity 46, and connects the second cavity 46 to the air inlet 53 of the fan 20 only through the through hole 52. This makes it difficult for condensate to overcome the height difference and airflow resistance under the action of gravity, and to enter the fan 20 area of ​​the first cavity 44 through the through hole 52, thereby blocking the direct path of condensate into the fan 20.

[0066] Furthermore, the partition plate 41 separates the first cavity 44 and the second cavity 46, which can reduce the corrosion of the internal components of the fan 20 by condensate, reduce the probability of the fan 20 failing due to water ingress, extend the overall service life of the heat pump dryer 10, and reduce equipment maintenance costs.

[0067] In the illustrated embodiment, the air outlet of the fan 20 faces the second opening 32 and flows to the target location through the second housing 30 and the air guide duct. In one embodiment, a sealing ring is provided between the first housing 22 and the second housing 30 to seal the heat exchange duct formed by the base 14, the first housing 22, and the second housing 30.

[0068] Please see Figure 4 In some embodiments, the first cavity 44 is provided with a first opening 24, the first opening 24 is disposed opposite to the partition plate 41, and the side plate 26 is connected to the first cavity 44 to close the first opening 24.

[0069] Thus, by providing a first opening 24 in the first cavity 44, the connection between the side plate 26 and the first cavity 44 is facilitated.

[0070] Specifically, the partition plate 41 is positioned opposite to the first opening 24, and the air inlet 53 of the fan 20 faces the partition plate 41, communicating with the second cavity 46 through the through hole 52 on the partition plate 41. The side plate 26 closes the first opening 24, and the side of the fan 20 away from the air inlet 53 is fixed to the side plate 26, thereby allowing the air inlet 53 of the fan 20 to face the second through hole 52, facilitating the positioning and installation of the fan 20.

[0071] In the illustrated embodiment, the size of the first cavity 44 is adapted to the size of the fan 20. After the fan 20 is fitted with the vibration damping member 42, the vibration damping member 42 is squeezed and deformed and abuts against the inner wall of the first cavity 44. In this way, the vibration damping member 42 can seal the gap between the partition plate 41 and the fan 20, and prevent the gas inside the heat exchange duct from leaking out.

[0072] Please see Figure 2 and Figure 3 In some embodiments, the heat pump drying device 10 includes a vibration damper 42, which is sleeved on at least a portion of the surface of the fan 20. At least a portion of the vibration damper 42 is engaged in the first opening 24 so that the first cavity 44 is sealed to the side plate 26.

[0073] Thus, the damping component 42 seals the connection between the first housing 22 and the side plate 26, preventing gas from leaking between the first housing 22 and the side plate 26.

[0074] Specifically, the size of the first opening 24 matches the size of the fan 20. When the fan 20 is installed on the side plate 26 and the side plate 26 closes the first opening 24, the vibration damping member 42 on the outside of the fan 20 is squeezed and deformed, and is stuck at the first opening 24, so that the side plate 26 can seal the first opening 24 and prevent the gas inside the heat exchange duct from leaking out.

[0075] In one embodiment, a sealing ring is provided around the periphery of the first opening 24. When the side plate 26 closes the first opening 24, it is connected to the side plate 26 through the sealing ring, thereby sealing the first opening 24. Furthermore, the sealing ring can absorb the vibration transmitted from the fan 20 to the first housing 22 to a certain extent, which helps to reduce the impact of the fan 20 vibration on the first housing 22.

[0076] Please see Figure 5 In some embodiments, the fan 20 is mounted on the side plate 26 by fasteners, and the bottom of the fan 20 is spaced apart from the base plate 28.

[0077] This reduces the contact between the fan 20 and the base 14, thereby reducing the transmission path of the fan 20's vibration.

[0078] Specifically, the fan 20 is fastened to the side plate 26 with fasteners, and the bottom of the fan 20 is spaced apart from the base plate 28, cutting off the direct contact between the fan 20 and the base plate 28. This prevents vibration from being directly transmitted to the base plate 28 through the bottom, and instead transmits it indirectly through the single path of the side plate 26, greatly reducing the path of vibration transmission and thus reducing the vibration energy transmitted to other parts. At the same time, the side plate 26, base 14, and other components receive less vibration energy from the fan 20, and the wear between them and at the contact points with the fan 20 is significantly reduced, which helps protect the fan 20 and extend its service life.

[0079] Please see Figure 5 In some embodiments, the side plate 26 has a third mounting hole 50, the fan 20 has a fourth mounting hole, and the heat pump drying device 10 includes a second fastener, which passes through the third mounting hole 50 and the fourth mounting hole to fix the fan 20 and the side plate 26.

[0080] In this way, the fan 20 and the side plate 26 can be stably and reliably connected.

[0081] Specifically, the side plate 26 has a third mounting hole 50, and the fan 20 has a fourth mounting hole. During installation, the third and fourth mounting holes are aligned to achieve precise positioning. The second fastener passes through the third and fourth mounting holes, achieving a firm, stable, and reliable mechanical connection between the fan 20 and the side plate 26. The fastener connection can effectively withstand various forces generated by the fan 20 during operation, preventing the fan 20 from shifting, shaking, or even falling off during operation, thus ensuring the structural integrity of the heat pump drying device 10.

[0082] A stable connection provides a reliable support foundation for the fan 20, which helps the fan 20 maintain the correct posture and position during operation, reduces the increased vibration or component damage caused by unstable connection, ensures that the fan 20 can work continuously and smoothly, and guarantees the stability of its air volume and air pressure output.

[0083] Optionally, in one embodiment, the second fastener includes a screw that provides strong fastening force to tightly connect the fan 20 and the side plate 26 together, effectively preventing relative displacement or loosening between the fan 20 and the side plate 26, ensuring that the housing maintains a stable structure during use, and can withstand certain external forces and vibrations without easily separating.

[0084] Optionally, in one embodiment, the second fastener includes a vibration-damping screw. The vibration-damping screw can absorb and dissipate vibration energy. When the housing is subjected to external vibration or impact, the vibration-damping screw can reduce the transmission of vibration between the fan 20 and the side plate 26, thereby reducing the vibration amplitude of the entire heat exchange housing 16 and reducing noise caused by vibration. Simultaneously, in a vibrating environment, ordinary screw connections may gradually loosen due to vibration, affecting the stability of the connection. The vibration-damping characteristics of the vibration-damping screw can reduce this loosening caused by vibration, ensuring that the fan 20 and the side plate 26 always maintain a tight connection and maintain the normal operation of the equipment.

[0085] Please see Figure 6 In some embodiments, the base plate 28 has a mounting groove 54, and the first housing 22 has a mounting part 56, which is embedded in the mounting groove 54 to fix the base and the first housing 22 together.

[0086] Thus, the mounting slot 54 and the mounting part 56 can achieve the positioning and installation of the first housing 22 and the base plate 28.

[0087] Specifically, the base plate 28 has an installation groove 54, and the first housing 22 has an installation part 56. During installation, the installation part 56 can be quickly installed by simply aligning it with the installation groove 54 and inserting it in, without the need for complicated positioning operations, thus improving installation efficiency.

[0088] The cooperation between the mounting part 56 and the mounting groove 54 can form a tight connection between the first housing 22 and the base plate 28. The embedded structure can effectively limit the displacement of the first housing 22, ensure the stability of the connection between the two, and enhance the stability of the entire structure.

[0089] In some embodiments, the heat pump drying device 10 includes a vibration damping pad disposed between the base plate 28 and the first housing 22.

[0090] In this way, vibration transmission between the base plate 28 and the first housing 22 can be further avoided.

[0091] Specifically, the vibration damping pad is placed between the base plate 28 and the first housing 22, which can effectively block the vibration transmission path between the two. During operation, the fan 20 will generate a certain amount of vibration, which is transmitted from the side plate 26 to the base plate 28. The elastic material properties of the vibration damping pad can absorb and buffer this vibration energy, reduce the transmission of vibration from the base plate 28 to the first housing 22, and thus reduce the adverse effects of vibration on the entire device.

[0092] With reduced vibration, the noise caused by vibration will also decrease accordingly. Vibration transmission during the operation of the fan 20 may cause resonance in components such as the base plate 28, resulting in significant noise. The presence of vibration damping pads can suppress this resonance phenomenon, significantly reducing the noise generated by the fan 20 during operation.

[0093] In some embodiments, the base plate 28 is provided with an embedding groove, and the vibration damping pad is embedded in the embedding groove.

[0094] This facilitates the positioning and installation of the vibration damping pads.

[0095] Specifically, the embedded groove provides a precise installation position for the vibration damping pad, ensuring that the vibration damping pad is accurately positioned between the base plate 28 and the first housing 22, so as to give full play to its vibration damping function.

[0096] At the same time, the embedded groove provides stable support for the vibration damping pad, preventing it from shifting or deviating under the vibration generated by the operation of the fan 20. This ensures that the vibration damping pad can always effectively block the vibration transmission path between the first housing 22 and the base plate 28, making the vibration damping effect more stable and reliable.

[0097] In addition, the embedded groove facilitates the installation of the vibration damping pad, eliminating the need for complicated procedures and simplifying the installation process and time.

[0098] In summary, using sheet metal structural components as the fixed base 14 of the fan 20 can enhance the strength of the base 14; using screws and other strong constraint methods to fix the fan 20 can effectively reduce the shaking of the fan 20 itself; and setting vibration damping components 42 between the fan 20 and the base 14 can play a vibration damping role, thereby reducing the frictional shaking of the fan 20 and reducing low-frequency vibration noise.

[0099] The washing appliance provided by this utility model includes a heat pump drying device 10 according to any of the above embodiments.

[0100] In the aforementioned washing appliance, the fan 20 is fixedly connected to the side plate 26 of the base 14, and the first housing 22 is fixedly connected to the bottom plate 28 of the base 14. This can, to a certain extent, prevent the vibration of the fan 20 from causing resonance of the heat exchange housing 16, thereby avoiding affecting the airtightness of the heat exchange housing 16, and at the same time reducing the noise generated by the vibration of the fan 20 driving the heat exchange housing 16.

[0101] Specifically, washing appliances include, but are not limited to, dishwashers, dryers, sterilizers, or integrated kitchen appliances that combine washing and drying functions.

[0102] It should be noted that the above explanation of the implementation method and beneficial effects of the heat pump drying device 10 also applies to the washing appliances of the present invention. To avoid redundancy, it will not be elaborated in detail here.
