Description

Technical Field

[0001] This utility model relates to the field of dishwashers, and in particular to a dishwasher drying device and a dishwasher. Background Technology

[0002] In the field of existing drying equipment technology, common drying equipment structures have significant technical defects. One typical structure uses two shells to form a cavity, with components such as fans and heaters housed within the shells. However, because condensation occurs in the condensation channels within the shells, the two shells need to be heat-fused and re-formed to prevent leakage. This design means that when components such as heaters fail, the entire drying equipment becomes unrepairable due to structural solidification, requiring complete scrapping and severely impacting the equipment's lifespan and operating costs. Another structure uses multiple shells joined together, which reduces the difficulty of forming a single shell to some extent, but requires multiple sets of molds. This significantly increases mold costs, complicates the equipment structure, and leads to cumbersome and inefficient installation. Both of these existing technical solutions have significant shortcomings in terms of maintenance convenience, mold costs, and installation ease. There is an urgent need to propose a structurally optimized drying equipment design to address the problems of difficult component replacement and maintenance, high mold costs, and complex installation in existing technologies. Utility Model Content

[0003] Therefore, it is necessary to provide a dishwasher drying device and dishwasher to address the problems of difficult parts replacement and maintenance or high mold costs.

[0004] A dishwasher drying device includes:

[0005] The housing assembly includes a condensation channel and an air guide channel. The condensation channel is used to cool the flowing air. The housing assembly has a first air inlet and a first air outlet communicating with the condensation channel. The housing assembly also has a second air inlet and a second air outlet communicating with the air guide channel. The condensation channel has a condensate outlet in its channel wall. The condensation channel is connected to the air guide channel via the condensate outlet.

[0006] A heating component is detachably mounted on the housing assembly and is connected to the first air outlet and the second air inlet, respectively.

[0007] A fan assembly is disposed on the housing assembly and is used to input air cooled by the condensation channel into the heating assembly.

[0008] The dishwasher drying device disclosed in this application features an independently separated design of the condensation channel and the air guide channel in the housing assembly, forming a multi-stage air handling path. The condensation channel draws in humid, hot air from inside the dishwasher through a first air inlet, cools the air using the channel walls, causing water vapor in the air to condense into liquid water, which is then discharged into the air guide channel through the condensate outlet. This process effectively reduces air humidity, providing a low-humidity air source for subsequent drying. The air guide channel connects to the heating element through a second air inlet, delivering the condensed, low-humidity air to the heating element for heating. Simultaneously, the connection between the condensate outlet and the air guide channel allows for timely drainage of condensate, preventing water accumulation in the condensation channel from affecting cooling efficiency and ensuring continuous and stable operation of the condensation function. The heating element is detachably mounted on the housing assembly, facilitating user cleaning or replacement of the heating element and improving the device's maintenance convenience. The fan assembly, located on the housing assembly, forces the low-humidity air, cooled and dehumidified by the condensation channel, into the heating element. The low-humidity air is heated by the heating element to form dry hot air, which is then blown into the dishwasher through a second air outlet for rapid drying of the dishes.

[0009] In one embodiment, the housing assembly is integrally formed. By employing an integral forming process, the separation structure between the condensation channel and the air guide channel avoids the seam leakage problems that may occur with traditional splicing processes, significantly improving the sealing performance of the channel walls. Especially when the condensation channel is cooling air, the integrally formed channel walls ensure sealing, ensuring that condensate smoothly drains into the air guide channel through the condensate outlet.

[0010] In one embodiment, the housing assembly includes a first housing and a second housing, with the first housing disposed on the second housing, and the first and second housings being integrally formed. This integral forming process ensures the relative positional accuracy of the first and second housings, allowing for a more precise spatial layout of the condensation channel and the air guide channel. Even under long-term exposure to airflow impacts from the fan assembly and temperature changes from the heating assembly, the housing is less prone to deformation, thus ensuring the positional stability of the first air inlet, first air outlet, second air inlet, and second air outlet. This maintains the closed-loop flow path of humid and hot air from the first air inlet to the second air outlet, preventing airflow turbulence caused by housing deformation.

[0011] In one embodiment, a phase change material is also included, disposed on the housing assembly and adjacent to the condensation channel. The phase change material absorbs heat when the condensation channel cools the air, maintaining the low temperature of the channel walls through a solid-liquid phase change process. When hot, humid air flows through the condensation channel, the phase change material continuously absorbs heat from the air, accelerating the condensation rate of water vapor on the channel walls and increasing the amount of condensate generated. This allows for more efficient removal of moisture through the condensate outlet, improving the air dehumidification effect.

[0012] In one embodiment, the condensation channel includes a condensation guide channel and a mounting groove. An overflow port is formed on the housing assembly. The first air inlet, the condensation guide channel, the overflow port, the mounting groove, and the first air outlet are sequentially connected. The mounting groove is located on the surface of the housing assembly. The fan assembly is mounted on the housing assembly and located at the mounting groove. The fan assembly connects the overflow port and the first air outlet. The sequential connection of the first air inlet, the condensation guide channel, the overflow port, the mounting groove, and the first air outlet forms a stable airflow channel. After entering through the first air inlet, the humid and hot air is first thoroughly cooled and dehumidified by the condensation guide channel. The condensed liquid water is discharged through the condensate outlet. Subsequently, the air enters the fan assembly through the overflow port, is accelerated, and then exits through the first air outlet. The mounting groove is located on the surface of the housing assembly, and the fan assembly is embedded in the mounting groove for easy installation and removal.

[0013] In one embodiment, the fan assembly is connected to both the first air outlet and the second air inlet. The fan assembly serves as a connecting hub between the condensation channel and the air guide channel; its input end is connected to the first air outlet, allowing it to draw in low-humidity air cooled and dehumidified within the condensation channel; its output end is connected to the second air inlet, directly pressurizing the low-humidity air into the heating component.

[0014] In one embodiment, the fan assembly is at least partially located within the condensation channel, with its air inlet located within the condensation channel. The fan assembly is connected to the first air outlet, and the heating assembly is also connected to the first air outlet. Alternatively, a portion of the fan assembly extends through the first air outlet to the outside of the condensation channel and connects to the heating assembly, or a portion of the heating assembly extends through the first air outlet to the inside of the condensation channel and connects to the fan assembly. By directly positioning the fan assembly's air inlet within the condensation channel, dehumidified and cooled air can be drawn in real-time, avoiding the airflow delay and energy loss caused by the length of ductwork in traditional external fans. The fan assembly can directly input the dehumidified air into the heating assembly.

[0015] In one embodiment, the heating assembly includes a heating housing and a heating element. The heating housing has a heating channel and is detachably mounted on the housing assembly. The first air outlet connects to the second air inlet via the heating channel. The heating element is mounted on the heating housing and located within the heating channel. Because the heating housing is detachably mounted on the housing assembly, when the heating element accumulates dirt or malfunctions due to long-term use, the user does not need to disassemble the entire drying device; only the heating housing needs to be removed for cleaning or replacement of the heating element, significantly reducing maintenance difficulty. The heating element, located within the heating channel, can directly heat the flowing low-humidity air.

[0016] In one embodiment, at least a portion of the condensation channel is a meandering channel, with the first air inlet, the meandering channel, and the first air outlet sequentially connected. The meandering channel, through its winding path design, transforms a straight airflow channel into a multi-segment flow path. When humid, hot air enters from the first air inlet, it must turn multiple times along the bends of the meandering channel before exiting from the first air outlet. This allows for more sufficient heat exchange time between the humid, hot air and the channel walls, resulting in more complete water vapor condensation and increased condensate generation, thereby improving the air dehumidification effect.

[0017] In one embodiment, the second air outlet is located at the lowest point of the air guide channel relative to the horizontal plane, while the condensation channel, the heating component, and the fan assembly are at a higher horizontal plane than the second air outlet. Because the second air outlet is at the lowest point of the air guide channel, when a small amount of condensate enters the air guide channel with the dry hot air, it will naturally flow towards the second air outlet due to gravity, preventing accumulation within the channel. Simultaneously, the condensation channel, heating component, and fan assembly are at a higher horizontal plane than the second air outlet, forming a "high-level component - low-level outlet" drop structure. This ensures that condensate discharged into the air guide channel through the condensate outlet can flow smoothly to the outlet, completing drainage without additional power and preventing bacterial growth and channel corrosion caused by water accumulation.

[0018] In one embodiment, the condensation channel is located above the air guide channel. A mounting notch is provided on one side of the housing assembly, with a first air outlet on one side of the mounting notch and a second air inlet on the other side. The heating assembly is located at the mounting notch. Because the condensation channel is located above the air guide channel, the condensate outlet in its channel wall can directly drain condensate into the lower air guide channel by gravity, avoiding channel blockage caused by condensate accumulation. The mounting notch is located on one side of the housing assembly, with a first air outlet and a second air inlet on each side. After the heating assembly is embedded in this notch, it can directly connect the first air outlet and the second air inlet.

[0019] In one embodiment, the housing assembly is provided with a return channel, which is connected to both the condensate outlet and the air guide channel. The return channel is used to guide the condensate generated in the condensation channel into the air guide channel. By using the return channel as a dedicated drainage pipe independent of the airflow channel, the condensate generated in the condensation channel can be directly guided from the condensate outlet into the air guide channel, avoiding condensate residue on the channel wall or backflow into other components.

[0020] In one embodiment, a baffle plate is further included, which is disposed on the housing assembly and located within the air guide channel. A drainage channel is formed between the baffle plate and the channel wall of the air guide channel. The return channel, the drainage channel, and the second air outlet are sequentially connected. The baffle plate separates the airflow from the condensate within the air guide channel, and the drainage channel formed by the baffle plate and the channel wall serves as a dedicated drainage path, ensuring that the condensate introduced by the return channel flows along the drainage channel to the second air outlet, preventing the condensate from the return channel from being blown back into the condensation channel.

[0021] In one embodiment, a baffle plate is further included, disposed on the housing assembly and located within the condensation channel. The baffle plate covers the condensate outlet, and a liquid-passing gap is formed between the baffle plate and the channel wall of the condensation channel. The liquid-passing gap between the edge of the baffle plate and the channel wall of the condensation channel prevents airflow in the backflow channel from flowing back into the condensation channel through the condensate outlet.

[0022] A second aspect of this application discloses a dishwasher, comprising:

[0023] The aforementioned dishwasher drying unit.

[0024] The dishwasher disclosed in this application draws in hot and humid air through a first air inlet, cools and dehumidifies it through a condenser channel, then sends it to a heating element for heating by a fan assembly, and finally blows it onto the dishes through a second air outlet, thus achieving high drying efficiency.

[0042] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0044] The following describes some embodiments of the dishwasher drying apparatus and dishwasher according to the present invention with reference to the accompanying drawings.

[0045] Example 1

[0046] like Figures 1 to 10 As shown, this embodiment discloses a dishwasher drying device, including:

[0047] The housing assembly 1 is provided with a condensation channel 101 and an air guide channel 103. The condensation channel 101 is used to cool the flowing air. The housing assembly 1 has a first air inlet 104 and a first air outlet 105 communicating with the condensation channel 101. The housing assembly 1 has a second air inlet 106 and a second air outlet 107 communicating with the air guide channel 103. The channel wall of the condensation channel 101 has a condensate outlet 108. The condensation channel 101 is connected to the air guide channel 103 through the condensate outlet 108.

[0048] Heating component 2 is detachably mounted on housing component 1 and is connected to the first air outlet 105 and the second air inlet 106 respectively.

[0049] Fan assembly 3 is mounted on housing assembly 1 and is used to input air cooled by condensation channel 101 into heating assembly 2.

[0050] The dishwasher drying apparatus disclosed in this application features an independently separated design of the condensation channel 101 and the air guide channel 103 in the housing assembly 1, forming a multi-stage air handling path. The condensation channel 101 draws in humid, hot air from inside the dishwasher through the first air inlet 104. The air is cooled by the channel wall, causing water vapor in the air to condense into liquid water, which is then discharged into the air guide channel 103 through the condensate outlet 108. This process effectively reduces air humidity, providing a low-humidity air source for subsequent drying. The condensation channel 101 can consist only of the channel wall for condensation, or a condensation column can be installed internally to further enhance the condensation effect. The air guide channel 103 is connected to the heating assembly 2 through the second air inlet 106, allowing the condensed, low-humidity air to be delivered to the heating assembly 2 for heating. Simultaneously, the connection between the condensate outlet 108 and the air guide channel ensures timely drainage of condensate, preventing water accumulation in the condensation channel 101 from affecting cooling efficiency and ensuring continuous and stable operation of the condensation function. The heating element 2 is detachably mounted on the housing assembly 1, facilitating cleaning or replacement by the user and improving the device's maintenance convenience. The fan assembly 3, located on the housing assembly 1, forces the dehumidified air cooled by the condensation channel 101 into the heating element 2. This dehumidified air is heated by the heating element to form dry hot air, which is then blown into the dishwasher through the second air outlet 107 for rapid drying of the dishes.

[0051] In addition to the features of the above embodiments, this embodiment further specifies that the housing assembly 1 is integrally formed. By adopting an integral forming process, the separation structure between the condensation channel 101 and the air guide channel 103 avoids the seam leakage problems that may occur in traditional splicing processes, significantly improving the sealing performance of the channel wall. In particular, when the condensation channel 101 is cooling air, the integrally formed channel wall can ensure sealing performance, ensuring that the condensate is smoothly discharged into the air guide channel 103 through the condensate outlet 108.

[0052] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 1 includes a first housing 11 and a second housing 12, the first housing 11 is disposed on the second housing 12, and the first housing 11 and the second housing 12 are integrally formed. The integral forming process ensures the relative positional accuracy of the first housing 11 and the second housing 12, making the spatial layout of the condensation channel 101 and the air guide channel 103 more precise. Even under long-term airflow impact from the fan assembly 3 and temperature changes from the heating assembly 2, the housing is not easily deformed, thereby ensuring the positional stability of the first air inlet 104, the first air outlet 105, the second air inlet 106, and the second air outlet 107, maintaining the closed-loop flow path of hot and humid air from the first air inlet 104 to the second air outlet 107 unchanged, and avoiding airflow turbulence caused by housing deformation.

[0053] like Figure 1 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further includes a phase change material 6, which is disposed on the housing assembly 1 and adjacent to the condensation channel 101. The phase change material 6 absorbs heat when cooling air in the condensation channel 101, maintaining the low temperature of the channel wall through a solid-liquid phase change process. When hot and humid air flows through the condensation channel 101, the phase change material 6 continuously absorbs heat from the air, accelerating the condensation rate of water vapor on the channel wall and increasing the amount of condensate generated. This allows for more efficient removal of moisture through the condensate outlet 108, improving the air dehumidification effect.

[0054] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the condensation channel 101 includes a condensation guide channel 1011 and a mounting groove 1012; an overflow port 1013 is formed on the housing assembly 1; the first air inlet 104, the condensation guide channel 1011, the overflow port 1013, the mounting groove 1012, and the first air outlet 105 are sequentially connected; the mounting groove 1012 is located on the surface of the housing assembly 1; and the fan assembly 3 is disposed on the housing assembly 1 and located at the mounting groove 1012, connecting the overflow port 1013 and the first air outlet 105. Through the sequential connection structure of the first air inlet 104, the condensation guide channel 1011, the overflow port 1013, the mounting groove 1012, and the first air outlet 105, a stable airflow channel is formed. After entering through the first air inlet 104, the hot and humid air is first cooled and dehumidified by the condensation guide channel 1011. The condensed liquid water is discharged through the condensate outlet 108. Then, the air enters the fan assembly 3 through the overflow port 1013, is accelerated, and is discharged from the first air outlet 105. The mounting groove 1012 is located on the surface of the housing assembly 1. The fan assembly 3 is embedded in the mounting groove 1012, which facilitates the installation and removal of the fan assembly 3.

[0055] In addition to the features of the above embodiments, this embodiment further specifies that: the fan assembly 3 is connected to the first air outlet 105 and the second air inlet 106 respectively. The fan assembly 3 serves as the connecting hub between the condensation channel 101 and the air guide channel 103. Its input end is connected to the first air outlet 105, allowing it to draw in low-humidity air cooled and dehumidified within the condensation channel; its output end is connected to the second air inlet 106, directly pressurizing the low-humidity air into the heating assembly 2.

[0056] In addition to the features of the above embodiments, this embodiment further specifies that: the fan assembly 3 is at least partially located within the condensation channel 101; the air inlet of the fan assembly 3 is located within the condensation channel 101; the fan assembly 3 is connected to the first air outlet 105 and the heating assembly 2 is connected to the first air outlet 105; or a portion of the fan assembly 3 extends through the first air outlet 105 to the outside of the condensation channel 101 and connects with the heating assembly 2; or a portion of the heating assembly 2 extends through the first air outlet 105 to the inside of the condensation channel 101 and connects with the fan assembly 3. By directly setting the air inlet of the fan assembly 3 within the condensation channel 101, low-humidity air after cooling and dehumidification can be extracted in real time, avoiding the extraction delay and energy loss caused by the length of the pipeline in traditional external fans. The fan assembly 3 can directly input the dehumidified air into the heating assembly 2.

[0057] like Figure 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the heating assembly 2 includes a heating housing 21 and a heating element 22. The heating housing 21 is provided with a heating channel 201. The heating housing 21 is detachably mounted on the housing assembly 1. The first air outlet 105 connects to the second air inlet 106 via the heating channel 201. The heating element 22 is mounted on the heating housing 21 and located within the heating channel 201. Because the heating housing 21 is detachably mounted on the housing assembly 1, when the heating element 22 accumulates dirt or malfunctions due to long-term use, the user does not need to disassemble the entire drying device; only the heating housing 21 needs to be disassembled to clean or replace the heating element 22, greatly reducing maintenance difficulty. The heating element 22, located within the heating channel 201, can directly heat the low-humidity air flowing through it.

[0058] like Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that at least a portion of the condensation channel 101 is a meandering channel, and the first air inlet 104, the meandering channel, and the first air outlet 105 are sequentially connected. Through the meandering channel and its winding path design, the straight airflow channel is transformed into a multi-segment flow path. When humid and hot air enters from the first air inlet 104, it needs to turn multiple times along the bends of the meandering channel before being discharged from the first air outlet 105. This allows for more sufficient heat exchange time between the humid and hot air and the channel wall, resulting in more complete water vapor condensation and increased condensate generation, thereby improving the air dehumidification effect.

[0059] like Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second air outlet 107 is located at the lowest point of the air guide channel 103 relative to the horizontal plane, and the horizontal plane of the condensation channel 101, heating component 2, and fan component 3 is higher than the horizontal plane of the second air outlet 107. Since the second air outlet 107 is at the lowest point of the air guide channel 103 relative to the horizontal plane, when a small amount of condensate enters the air guide channel 103 with dry hot air, it will naturally flow to the second air outlet 107 due to gravity, avoiding accumulation in the channel. Simultaneously, the horizontal plane of the condensation channel 101, heating component 2, and fan component 3 is higher than the second air outlet 107, forming a "high-level component - low-level outlet" drop structure, ensuring that the condensate discharged into the air guide channel 103 through the condensate outlet 108 of the condensation channel 101 can flow smoothly to the outlet, completing drainage without additional power, and avoiding bacterial growth and channel corrosion caused by water accumulation.

[0060] like Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the condensation channel 101 is located above the air guide channel 103; a mounting notch 109 is provided on one side of the housing assembly 1; a first air outlet 105 is provided on one side of the mounting notch 109; a second air inlet 106 is provided on the other side of the mounting notch 109; and the heating assembly 2 is located at the mounting notch 109. Because the condensation channel 101 is located above the air guide channel 103, the condensate outlet 108 opened in its channel wall can directly discharge condensate into the lower air guide channel 103 by gravity, avoiding channel blockage caused by condensate accumulation. The mounting notch 109 is located on one side of the housing assembly 1, with a first air outlet 105 and a second air inlet 106 respectively provided on its two sides. After the heating assembly 2 is embedded in this notch, it can directly connect the first air outlet 105 and the second air inlet 106.

[0061] like Figure 7 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is provided with a return channel 102, which is connected to the condensate outlet 108 and the air guide channel 103 respectively. The return channel 102 is used to guide the condensate generated in the condensation channel 101 into the air guide channel 103. By using the return channel 102 as a dedicated drainage pipe independent of the airflow channel, the condensate generated in the condensation channel 101 can be directly guided from the condensate outlet 108 into the air guide channel 103, avoiding condensate residue on the channel wall or backflow into other components.

[0062] like Figure 7 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further includes a baffle plate 4, which is disposed on the housing assembly 1 and located within the air guide channel 103. A drainage channel 401 is formed between the baffle plate 4 and the channel wall of the air guide channel 103. The return channel 102, the drainage channel 401, and the second air outlet 107 are sequentially connected. The baffle plate 4 separates the airflow from the condensate within the air guide channel 103. The drainage channel 401 formed by the baffle plate 4 and the channel wall serves as a dedicated drainage path, ensuring that the condensate introduced by the return channel 102 flows along the drainage channel 401 to the second air outlet 107, preventing the condensate from the return channel 102 from being blown back into the condensation channel 101.

[0063] like Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further includes a baffle plate 5, which is disposed on the housing assembly 1 and located within the condensation channel 101. The baffle plate 5 covers the condensate outlet 108, and a liquid passage gap 501 is formed between the baffle plate 5 and the channel wall of the condensation channel 101. The liquid passage gap 501 between the edge of the baffle plate 5 and the channel wall of the condensation channel 101 prevents airflow in the return channel 102 from flowing back into the condensation channel 101 through the condensate outlet 108.
