Description

Technical Field

[0001] The present invention relates to a water vapor separation device, a dishwasher inner container and a dishwasher, and is mainly used in the technical field of dishwashers. Background Art

[0002] After a dishwasher finishes washing dishes, the residual temperature remains high, and a large amount of moisture and water droplets remain in the inner tank. If this moisture is not removed, it will recondense as water droplets after cooling down and adhere to the inner wall and dishes, which can easily breed bacteria. If this moisture is removed directly, the humidity in the dishwasher will increase, and the moisture will adhere to the outer shell of the dishwasher, affecting the kitchen environment.

[0003] Dishwasher drying methods include natural drying through residual heat from the inner tank, using fans to enhance air circulation within the tank to remove moisture, further enhancing drying by using heating elements such as PTC to heat the air, or using compressors to condense moisture and heat the air. Using auxiliary drying methods (PTC heating drying, compressor condensation drying) increases energy consumption, increases the size of the device, and thus reduces the cleaning space. Furthermore, these methods may take a long time to dry, have poor drying results, and easily lead to the growth of microorganisms inside the tank; or they may not effectively solve the problems of water vapor separation and moisture discharge.

[0004] In one prior art technology related to a dishwasher, a working box is fixedly connected to one side of the dishwasher body. A connecting pipe is fixedly connected to the side of the working box adjacent to the dishwasher body. A first connecting flange is fixedly connected to the end of the connecting pipe away from the working box. When the dishwasher is performing drying and drying operations, the water vapor separator is opened to separate the water vapor generated in the dishwasher's inner tank. While the water vapor separator is opened, the circulating fan is turned on simultaneously, so that the circulating fan can draw the dry water vapor filtered by the water vapor separator from the outlet pipe into the inlet pipe, and then use wind power to return the dry water vapor to the dishwasher's inner tank. In this prior art, a circulating fan is required to cooperate with the water vapor separator for water vapor separation. Moreover, the drying efficiency is low and it is prone to airflow blockage or circulation problems. In addition, if the circulating fan is not properly maintained, it is easy to introduce dirt during startup, causing internal contamination.

[0005] Another prior art device for a dishwasher drying apparatus and its use method includes a dishwasher housing, a condensing and heating device, and a drying spray device. The dishwasher housing includes an inner housing, an outer housing, and a door panel. The condensing and heating device is disposed between the inner and outer housings and includes a micro-fan, a steam-water cyclone separator, and a heating device. The micro-fan is embedded in the inner housing to extract water vapor from the inner housing. The micro-fan is connected to the steam-water cyclone separator via an air duct, which is connected to the heating device via a gas connection pipe. The heating device is connected to the drying spray device, which is connected to the steam-water cyclone separator via a condensate guide pipe. This prior art device includes numerous devices and apparatus, resulting in high cost, high energy consumption, and large size. It also suffers from low drying efficiency and the risk of internal contamination. Summary of the Invention

[0015] As a further improvement of the present invention, the secondary water vapor separation structure includes a guide member and a drainage gap formed between the enclosing member and the guide member, and the drainage gap connects the drainage channel and the centrifugal diffusion space.

[0016] As a further improvement of the present invention, the guide is formed by extending downward from the end surface of the shell and is located on the inner side of the enclosing member.

[0017] As a further improvement of the present invention, the enclosing member has an air guide annular surface close to the impeller, and the air guide annular surface is used to guide the gas separated from the water vapor under the action of centrifugation to the air outlet.

[0018] As a further improvement of the present invention, the shell has a cover, and the cover has a central hollow and an outer ring hollow. The central hollow forms the steam inlet, and the outer ring hollow forms the air outlet.

[0019] As a further improvement of the present invention, the shell is provided with a filter fence in the central hollow portion, for preventing debris from entering the shell.

[0020] As a further improvement of the present invention, the shell is provided with a plurality of partition bars to divide the outer ring hollow into a plurality of air outlet areas, and the shell is provided with a plurality of guide grilles arranged at intervals in the air outlet areas.

[0021] As a further improvement of the present invention, the air outlet area is divided along the circumference of the outer ring hollowing.

[0022] As a further improvement of the present invention, the guide grille is inclined to the axial direction of the cover, so as to guide the direction of the outgoing air away from the central hollow.

[0026] A dishwasher liner, comprising:

[0027] liner;

[0028] At least one of the water vapor separation devices is arranged on the inner wall of the inner container.

[0029] As a further improvement of the present invention, a cover is provided on the inner tank wall, the water vapor separation device is provided in the cover, and a drainage groove is provided at the bottom of the cover.

[0030] As a further improvement of the present invention, the cover shell includes a receiving groove formed on the inner container wall and an inner container cover covering the receiving groove.

[0031] A dishwasher is provided with the dishwasher inner container.

[0032] Beneficial effects of the present invention:

[0033] 1. The water vapor separation device of the present application can perform multiple water vapor separations on the hot and humid air in the inner environment of the inner container, generating dry hot air that is then fed back into the inner environment of the inner container for drying. Based on the water vapor separation mechanism of this embodiment, the inner environment of the inner container can form a fully enclosed internal circulation airflow. While being able to dry the bowls in the inner container, there is no need to introduce external drying gas, thereby preventing contamination of the inner environment of the inner container.

[0034] 2. Under the centrifugal force, the hot and humid gas can quickly diffuse to the surrounding area in the centrifugal diffusion space and impact the enclosing components. The primary water vapor separation structure on the enclosing components performs water vapor separation treatment, which can gradually separate the water contained in the hot and humid gas, thereby generating dry hot gas;

[0035] 3. A secondary water vapor separation device is provided on the basis of the primary water vapor separation structure. It can take effect when the water vapor separation of the primary water vapor separation structure reaches the upper limit threshold, reducing the drainage pressure of the primary water vapor separation structure, so that the hot and humid gas can be separated on the enclosing component and form more water droplets or water films, so that the water in the hot and humid gas can be more fully separated. It is particularly suitable for hot and humid gas with a high water content;

[0036] 4. The air guide annular surface of the enclosing component can guide the gas impacting the enclosing component and direct it to the air outlet, thereby improving the flow efficiency and speed of the drying hot air;

[0037] 5. The cover provided on the casing strengthens the structural strength of the casing at the air inlet and outlet. The filter fence located at the central hollowing part filters debris, preventing it from entering the casing along with the hot and humid gas, thereby avoiding damage to the impeller blades. The division of the air outlet area and the guide grille guide the outlet direction of the dry hot gas, guiding the outlet direction away from the central hollowing part. On the one hand, this can avoid mutual interference between the inlet and outlet steam and avoid insufficient outlet volume of the dry hot gas. On the other hand, it can make the dry hot gas outlet quickly spread to the periphery, thereby increasing the radiation range of the drying and enhancing the drying effect.

[0038] 6. The cover has two configurations. One is fixed on the casing, which has a relatively strong overall structure. The other is that it can rotate synchronously with the start-up of the impeller, thereby further expanding the radiation range of the dry hot air to obtain a better drying effect.

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and implementation examples.

[0048] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0049] Implementation Case 1:

[0050] Reference Figure 1 、 Figure 2A water vapor separation device includes a housing 1, an impeller 2, an enclosing member 3, and a primary water vapor separation structure 4. The housing 1 has a steam inlet 11 and an air outlet 12. The air outlet 12 and the steam inlet 11 are located on the same surface of the housing 1, and the air outlet 12 is arranged around the steam inlet 11. The water vapor separation device of this embodiment is used in the inner tank of a dishwasher. The hot and humid gas in the inner tank is fed into the steam inlet 11. The hot and humid gas is separated from the water vapor in the housing 1 and generates dry hot gas. The dry hot gas is output from the air outlet and dries the internal environment of the inner tank.

[0051] In this embodiment, the impeller 2 is disposed within the housing 1, and the steam inlet space 1A within the impeller 2 is connected to the steam inlet 11 on the housing 1. The housing 1 is equipped with a drive motor to drive the impeller 2 to rotate. The rotation of the impeller 2 creates a negative pressure environment, thereby drawing hot and humid gas from the steam inlet 11 into the steam inlet space 1A.

[0052] The enclosing member 3 is disposed within the housing 1 and surrounds the impeller 2. The enclosing member 3 and the edge of the impeller 2 are spaced a certain distance apart, thereby defining a centrifugal diffusion space 1B between the enclosing member 3 and the impeller 2. The centrifugal diffusion space 1B is connected to the air outlet 12. The primary water vapor separation structure 4 is disposed on the enclosing member 3.

[0053] The humid hot gas enters the shell 1 from the steam inlet 11, rotates in the steam inlet space 1A due to the rotation of the impeller 2, and enters the centrifugal diffusion space 1B from the steam inlet space 1A under the centrifugal action, diffuses to the surroundings and impacts the enclosing member 3. The humid hot gas is subjected to water vapor separation treatment by the primary water vapor separation structure 4, which can gradually separate the moisture it contains, thereby generating dry hot gas, and finally the dry hot gas is output from the air outlet 12 to dry the internal environment of the liner.

[0054] The water vapor separation device in this embodiment can perform multiple water vapor separations on the hot and humid air within the inner container, generating dry hot air that is then fed back into the inner container for drying. This water vapor separation mechanism creates a fully enclosed, internally circulating airflow within the inner container, effectively drying the bowls within it without requiring external drying air, thus preventing contamination of the inner container.

[0055] In this embodiment, a drain channel 6 is provided outside the enclosing member 3. The primary water vapor separation structure 4 includes multiple dehydration ports 41 formed on the enclosing member 3. The dehydration ports 41 connect the drain channel 6 to the centrifugal diffusion space 1B. Driven by the impeller 2, the hot and humid gas impacts the enclosing member 3 under centrifugal force, forming flowing water droplets. These droplets then flow through the dehydration ports 41 into the drain channel 6, thus achieving water vapor separation. If the hot and humid gas contains a high water content, a thin, flowing water film forms on the enclosing member 3. This water film is continuously discharged into the drain channel 6 through the dehydration ports 41. The dehydration ports 41 can be configured as holes or slots.

[0056] In this embodiment, there is at least one drain outlet 13 on the shell 1. The number and position distribution of the drain outlets 13 need to be reasonably set according to actual needs. The drain outlet 13 is connected to the drain channel 6. The water separated from the humid and hot gas and entering the drain channel 6 is finally discharged outside the shell 1 through the drain outlet 13.

[0057] In this embodiment, the enclosing member 3 has an air-guiding annular surface 3a located near the impeller 2. Typically, this surface 3a is the inner surface of the enclosing member 3. The direction of flow of the moist hot gas within the centrifugal diffusion space 1B is inconsistent with the direction of flow that ultimately leads to the dry hot gas outlet 12. The function of the air-guiding annular surface 3a is to guide the gas impacting the enclosing member 3 toward the outlet 12, thereby improving the flow efficiency and velocity of the dry hot gas. In this embodiment, the diameter of the air-guiding annular surface 3a gradually increases along the direction of flow of the dry hot gas from the outlet 12, resulting in the air-guiding annular surface 3a appearing sloped in cross-section.

[0058] Implementation Case 2:

[0059] Reference Figure 3 Combined with Figure 2 , a water vapor separation device. The water vapor separation device of this embodiment is based on embodiment 1, and a secondary water vapor separation structure 5 is further provided on the enclosing component 3, and the secondary water vapor separation structure 5 is close to the air outlet 12, and the primary water vapor separation structure 4 is far away from the air outlet 12, so that the hot and humid gas can be subjected to two water vapor separation treatments through the primary water vapor separation structure 4 and the secondary water vapor separation structure 5.

[0060] In Example 1, for hot and humid gas with a low water content, the water can be removed by processing through the primary water vapor separation structure 4, and dry hot gas is discharged from the outlet 12. For hot and humid gas with a high water content, a flowing water film is formed on the enclosing member 3. When the water film reaches a certain thickness, it is limited by the saturation of the flow rate of the dehydration port 41, and the hot and humid gas cannot release more water. It should be noted that the size and number of the dehydration ports 41 on the enclosing member 3 are limited to avoid air leakage. Therefore, the water separation capacity of the primary water vapor separation structure 4 has an upper threshold. When the water content in the hot and humid gas is high and the primary water vapor separation structure 4 is unable to completely separate the water in the hot and humid gas, a secondary water vapor separation structure 5 is required to perform secondary water vapor separation to reduce the drainage pressure of the primary water vapor separation structure, thereby allowing the hot and humid gas to separate on the enclosing member 3 and form more water droplets or water films, so that the water in the hot and humid gas is more fully separated.

[0061] In this embodiment, the secondary water vapor separation structure 5 includes a guide member 51 and a drainage gap 52. The guide member 51 is located on the inner side of the enclosing member 3. The drainage gap 52 is formed between the guide member 51 and the enclosing member 3. The drainage gap 52 connects the drain channel 6 and the centrifugal diffusion space 1B. The water film formed on the enclosing member 3 is discharged into the drain channel 6 through the dehydration port 41. When the flow rate of the dehydration port 41 reaches saturation and cannot discharge further water, the water film is discharged into the drain channel 6 through the drainage gap 52. In addition, the air guide annular surface 3a not only guides the dry hot air out of the air outlet 12 but also guides the flow of the water film toward the drainage gap 52, thereby further improving the drainage efficiency of the drainage gap 52.

[0062] In addition, the spacing distance between the guide 51 and the enclosing member 3 should not be too large, that is, the width of the drainage gap 52 should not be too large to avoid air leakage. The width of the drainage gap 52 should be adapted to the maximum thickness of the water film formed.

[0063] Implementation Case 3:

[0064] Reference Figure 4 A water vapor separation device, compared to Example 1 or Example 2, has a cover 7 on housing 1 in this embodiment. Cover 7 has a central hollow 71 and an outer ring hollow 72. Central hollow 71 forms housing 1's steam inlet 11, while outer ring hollow 72 forms housing's air outlet 12. Hot and humid gas enters housing 1 through central hollow 71 and steam inlet 11, respectively. Dry hot gas, generated after water vapor separation, is output to the exterior of housing 1 through the annular outlet and outer ring hollow 72. Cover 7 strengthens the structural strength of housing 1 at air inlet 11 and air outlet 12.

[0065] In this embodiment, a filter fence 73 is provided at the central hollow 71 of the shell 1. The filter fence 73 filters debris to prevent the debris from entering the shell 1 along with the hot and humid gas, thereby preventing the debris from interfering with the rotation of the impeller 2 and damaging the blades of the impeller 2.

[0066] In this embodiment, the shell 1 is provided with a plurality of partition bars to divide the outer ring hollow 72 into a plurality of air outlet areas 721 along the circumferential direction. The shell 1 is provided with a plurality of spaced guide grilles 74 in the air outlet area 721. The guide grilles 74 guide the outlet direction of the dry hot air. The guide grilles 74 are inclined to the axial direction of the cover 7 and are inclined toward the periphery at a certain angle along the overall air outlet direction, so that the guide grilles 74 guide the outlet direction away from the central hollow 71. On the one hand, it can avoid mutual interference between the incoming steam and the outgoing air, and avoid part of the dry hot air from re-entering the shell 1 from the central hollow 71, resulting in insufficient outlet volume of the dry hot air. On the other hand, it can make the dry hot air outlet quickly spread to the periphery, thereby increasing the radiation range of drying and enhancing the drying effect.

[0067] In this embodiment, the cover 7 is fixed to the housing 1 , so the distribution positions of the air outlet area 721 and the guide grille 74 are fixed, that is, the radiation range of the dry hot air output by the outer ring hollow 72 is fixed.

[0068] Implementation Case 4:

[0069] Reference Figure 5 、 Figure 6 , a water vapor separation device. Compared with implementation case 3, the cover 7 of this implementation case is rotatably connected to the shell 1, and the cover 7 can rotate around its own central axis relative to the shell 1. The cover 7 rotates with the output of the dry hot air, thereby further expanding the radiation range of the dry hot air to obtain a better drying effect.

[0070] In this embodiment, the impeller 2 is provided with a fixed shaft 21 at its center. The fixed shaft 21 extends along the axial direction of the impeller 2 and toward the central hollow 71. The cover 7 is provided with a bearing 75 at its center. The bearing 75 is specifically provided on the filter fence 73. The bearing 75 is rotatably sleeved on the fixed shaft 21, so that the cover 7 can rotate around the fixed shaft 21 relative to the housing 1. The friction between the bearing 75 and the fixed shaft 21 should be as small as possible. A certain amount of lubricating oil can be appropriately added to improve its rotation flexibility. The guide grille 74 of the outlet area 721 is arranged differently relative to the center of the cover 7, such as Figure 6 As shown, the arrangement direction of the guide grille 74a of the air outlet area 721a relative to the center of the cover 7 is different from that of the guide grilles 74 of the other air outlet areas 721, so when air is discharged, a torque that causes the cover 7 to rotate counterclockwise can be generated.

[0071] Implementation Case 5:

[0072] Reference Figure 7 A dishwasher inner tank includes an inner tank and at least one water vapor separation device J. The number of water vapor separation devices J should be reasonably set according to actual drying needs. The water vapor separation device J is shown in Example 1-4.

[0073] In this embodiment, the water vapor separation device J is arranged on the inner wall K of the inner container.

[0074] In this embodiment, a cover L is provided on the inner liner, a water vapor separation device J is provided in the cover L, and a drainage groove LA is provided at the bottom of the cover L. The water separated by the water vapor separation device J is discharged from the shell 1 through the drain port 13 and is discharged from the cover L through the drainage groove LA. The separated water flows to the bottom of the inner liner and is discharged from the inner liner after the inner liner is dried.

[0075] In this embodiment, the housing L includes a receiving slot L1 and an inner liner cover L2. The receiving slot L1 is formed by a recess in the inner liner wall K, and the inner liner cover L2 seals over the receiving slot L1. Furthermore, the housing L has openings corresponding to the steam inlet 11 and the air outlet 12 for the input of moist hot air and the output of dry hot air. The inner liner cover L2 is fixed to the inner liner wall K with fasteners, facilitating removal and installation.

[0076] Implementation Case 6:

[0077] A dishwasher has a dishwasher inner tank, and the dishwasher inner tank is as shown in implementation cases 1-4.

[0078] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
