Description

A water vapor separation device, a dishwasher inner tank, and a dishwasher Technical Field

[0001] This invention relates to a water vapor separation device, a dishwasher inner tank, and a dishwasher, and is mainly applied in the technical field of dishwashers. Background Technology

[0002] After a dishwasher finishes washing, the dishes remain warm, and there is still a lot of moisture and water droplets inside the drum. If this moisture is not dehumidified, it will condense back into water droplets after cooling and adhere to the inner walls and dishes, easily breeding bacteria. If the moisture is directly removed, the humidity in the dishwasher environment will increase, and the moisture will adhere to the dishwasher's exterior, affecting the kitchen environment.

[0003] Dishwashers use various drying methods, including natural drying via residual heat from the inner drum, enhanced airflow through a fan to remove moisture, enhanced drying with PTC heating elements, or condensation drying and air heating via a compressor. However, using auxiliary drying methods (PTC heating or compressor condensation drying) increases energy consumption, increases the size of the appliance, and consequently reduces the washing space. Furthermore, these methods either have longer drying times, poorer drying results, and can lead to microbial growth inside the dishwasher; or they do not effectively address the issues of moisture separation and removal.

[0004] In a prior art dishwasher, a work tray is fixedly connected to one side of the dishwasher body, and a connecting pipe is fixedly connected to the side of the work tray adjacent to the dishwasher body. A first connecting flange is fixedly connected to the end of the connecting pipe away from the work tray. During the drying process, the water vapor separator is activated to separate the water vapor generated inside the dishwasher tub. Simultaneously, a circulating fan is activated, drawing the dried water vapor filtered by the water vapor separator from the exhaust pipe into the intake pipe, and then using airflow to re-enter the dishwasher tub. This prior art requires a circulating fan to work with the water vapor separator for water vapor separation, and the drying efficiency is low, prone to airflow blockage or circulation problems. Furthermore, improper maintenance of the circulating fan can easily introduce dirt and cause internal contamination during startup.

[0005] In another prior art drying device for dishwashers and its usage method, the device includes a dishwasher cabinet, a condenser and heating device, and a drying spray device. The dishwasher cabinet includes an inner cabinet, an outer cabinet, and a door panel. The condenser and heating device is located between the inner and outer cabinets and includes a miniature fan, a steam-water cyclone separator, and a heating device. The miniature fan is embedded in the inner cabinet to extract water vapor from it. The miniature fan is connected to the steam-water cyclone separator via an exhaust pipe. The steam-water cyclone separator is connected to the heating device via a gas connecting pipe. The heating device is connected to the drying spray device. The steam-water cyclone separator is connected to the drying spray device via a condensate guide pipe. This prior art involves numerous devices and appliances, resulting in high cost, high energy consumption, and large size for the drying device. It also suffers from low drying efficiency and susceptibility to internal contamination. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a water vapor separation device, a dishwasher inner tank and a dishwasher, forming a completely closed internal circulation structure. The structure is relatively simple, the water vapor separation effect is good and the efficiency is high, and a relatively complete drying mechanism is provided.

[0007] The present invention is achieved through the following technical solution.

[0008] A water vapor separation device, comprising:

[0009] The casing has an inlet and at least one outlet.

[0010] An impeller located within the housing defines the steam inlet space it occupies and is connected to the steam inlet.

[0011] At least one air duct, one end of which is connected to the steam inlet space and the other end of which is connected to the corresponding air outlet. The air duct is provided with a primary water vapor separation structure in the part near the steam inlet space and a secondary water vapor separation structure in the part downstream of the primary water vapor separation structure.

[0012] As a further improvement of the present invention, the air duct has two air duct walls, and the inner sides of the two air duct walls are provided with inner enclosure walls that have gaps with the air duct walls. A drainage channel is defined between the air duct walls and the inner enclosure walls for receiving water separated by the primary water vapor separation structure and the secondary water vapor separation structure.

[0013] As a further improvement of the present invention, the primary water vapor separation structure includes a first part of the inner wall having a plurality of dewatering ports and the air duct wall. The dewatering ports are arranged at intervals along the extending direction of the first part of the inner wall and are connected to the air duct and the drainage duct.

[0014] As a further improvement of the present invention, the air duct has at least one bend, and the bend is provided with the primary water vapor separation structure.

[0015] As a further improvement of the present invention, the primary water vapor separation structure is provided at the duct wall where the bending portion has a larger turning radius.

[0016] As a further improvement of the present invention, the extension direction of the air duct connecting the steam inlet space is along the tangential direction of the impeller.

[0017] As a further improvement of the present invention, the first-stage water vapor separation structure is provided at the duct wall away from the impeller in the part of the duct connecting the steam inlet space.

[0018] As a further improvement of the present invention, the secondary water vapor separation structure includes a guide rail having a gap with the inner wall, a second part of the inner wall corresponding to the guide rail, and a drainage branch defined between the guide rail and the second part of the inner wall.

[0019] As a further improvement of the present invention, the inner wall of the second part has a drainage connection port connecting the drainage branch and the drainage channel.

[0020] As a further improvement of the present invention, the drainage connection is located downstream of the inner wall of the second part.

[0021] As a further improvement of the present invention, a drainage guide channel that crosses the air duct is connected between the two drainage channels.

[0022] As a further improvement of the present invention, the housing is provided with a drain outlet, which is connected to one of the drain channels.

[0023] As a further improvement of the present invention, the steam inlet and the steam outlet are located on the same shell surface of the housing.

[0024] As a further improvement of the invention, it is centrally symmetrical about the impeller.

[0025] As a further improvement of the present invention, two air ducts are provided.

[0026] A dishwasher inner liner, comprising:

[0027] Inner liner;

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

[0029] As a further improvement of the present invention, a cover is provided on the inner wall of the liner, the water vapor separation device is disposed inside 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 includes a receiving groove formed on the inner wall and an inner cover sealing the receiving groove.

[0031] A dishwasher having the dishwasher inner tub.

[0032] The beneficial effects of this invention are:

[0033] 1. The water vapor separation device of this application can perform multiple water vapor separations on the humid and hot gas in the inner environment of the inner liner and generate dry hot gas, which is then fed back into the inner environment of the inner liner for drying. Based on the water vapor separation mechanism of this embodiment, the inner environment of the inner liner can form a fully closed internal circulation airflow. Under the premise of drying the bowls in the inner liner, there is no need to introduce external drying gas, thereby avoiding the contamination of the inner environment of the inner liner.

[0034] 2. Under centrifugal force, the hot and humid gas enters the air duct from the steam inlet space and forms flowing water droplets on the inner wall. When it flows through the first part of the inner wall, it enters the drain through the dehydration port, thus forming a first-stage water vapor separation, which can perform relatively sufficient water vapor separation on the hot and humid gas entering the shell.

[0035] 3. The air duct extends in a linear shape. The hot and humid gas flows from one end connected to the centrifugal diffusion space to the other end connected to the air outlet. The air duct has multiple primary water vapor separation structures arranged along the flow path of the hot and humid gas. The multiple primary water vapor separation structures perform multiple and sufficient primary water vapor separation on the hot and humid gas. The linear extension of the air duct with its narrow structure can support this primary water vapor separation mechanism.

[0036] 4. Due to the water vapor separation mechanism of the dehydration port, the number of dehydration ports should not be too large to avoid insufficient output of dry hot air from the outlet due to air leakage. The primary water vapor separation structure can be arranged in the air duct, such as at the bend of the air duct wall with a large turning radius, or at the air duct wall away from the impeller in the part of the air duct connecting to the steam inlet space, to maximize the effect of primary water vapor separation.

[0037] 5. Moist and hot gas forms flowing water droplets or water films on the inner wall. After the first-stage water vapor separation structure, the residual amount of water droplets is small or the thickness of the flowing water film is thin. When the gap between the guide rail of the second-stage water vapor separation structure and the first part of the inner wall is small, all of them can enter the drainage branch, forming a second-stage water vapor separation and achieving a more thorough water vapor separation effect.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0045] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0046] Implementation Case 1:

[0047] Referring to Figures 1-4, a water vapor separation device includes a housing 1, an impeller 2, at least one air duct 3, a primary water vapor separation structure 4, and a secondary water vapor separation structure 5. The housing 1 has a steam inlet 11 and at least one air outlet 12. In this embodiment, the water vapor separation device is used in the inner tub of a dishwasher. The humid and hot gas in the inner tub is sent into the steam inlet 11, where water vapor is separated from the humid and hot gas inside the housing 1 to generate dry hot gas. The dry hot gas is output from the air outlet 12 to dry the internal environment of the inner tub.

[0048] In this embodiment, the impeller 2 is disposed inside the housing 1, and the steam inlet space 1A inside the impeller 2 is connected to the steam inlet 11 on the housing 1. The housing 1 has a built-in drive motor to drive the impeller 2 to rotate. The rotation of the impeller 2 creates a negative pressure environment, which allows hot and humid gas to be drawn from the steam inlet 11 into the steam inlet space 1A.

[0049] The number of air ducts 3 and air outlets 12 is the same. The air duct 3 is defined by the air duct wall 31. One end of the air duct 3 is connected to the steam inlet space 1A, and the other end is connected to the corresponding air outlet 12. The air duct 3 has at least one bend 3-1. The air duct 3 has a primary water vapor separation structure 4 near the steam inlet space 1A and a secondary water vapor separation structure 5 near the air outlet 12. The air duct wall 31 can be independently set inside the shell 1, or it can be formed by the side wall of the shell 1.

[0050] After entering the steam inlet space 1A, the humid and hot gas rotates with the operation of the impeller 2. It leaves the impeller 2 by inertia and enters the air duct 3 through the steam inlet space 1A under the centrifugal force. The humid and hot gas entering the air duct 3 undergoes water vapor separation treatment by the primary water vapor separation structure 4 and secondary water vapor separation treatment by the secondary water vapor separation structure 5. Through multiple and continuous water vapor separation, the humid and hot gas can gradually remove the moisture it contains, thereby generating dry hot gas. Finally, the dry hot gas is output from the air outlet 12 to dry the internal environment of the inner tank.

[0051] In this embodiment, since the air duct 3 has at least one bend 3-1, the bend 3-1 can change the extension direction of the air duct 3, which can not only extend the flow path of the hot and humid gas, but also cause the hot and humid gas to collide with the inner wall 6 described later when passing through the bend 3-1, so that more flowing water droplets can be formed on the inner wall 6. This can better cooperate with the structure of the primary water vapor separation structure 4 and the secondary water vapor separation structure 5 described later to perform primary water vapor separation and secondary water vapor separation.

[0052] The water vapor separation device in this embodiment can perform multiple water vapor separations on the humid and hot gases in the inner environment of the liner, generating dry hot gases, which are then fed back into the inner environment of the liner for drying. Based on the water vapor separation mechanism of this embodiment, a fully enclosed internal circulation airflow is formed in the inner environment of the liner. While drying the bowls in the liner, there is no need to introduce external drying gases, thereby avoiding contamination of the inner environment of the liner.

[0053] In this embodiment, the inner sides of both air duct walls 31 are provided with inner enclosure walls 6 that have gaps with the air duct walls 31. A drainage channel 7A is defined between the air duct walls 31 and the inner enclosure walls 6. The function of the drainage channel 7A is to receive the water separated by the primary water vapor separation structure 4 and the secondary water vapor separation structure 5.

[0054] In this embodiment, the first-stage water vapor separation structure 4 includes a first inner wall 61 and an air duct wall 31. The first inner wall 61 is the part of the inner wall 6 where the first water vapor separation structure is located. The first inner wall 61 has multiple dewatering ports 611, which are spaced apart along the extension direction of the first inner wall 61. The dewatering ports 611 connect the air duct 3 and the drainage channel 7A. The shape of the dewatering ports 611 can be either a trough-shaped structure or a perforated structure.

[0055] Driven by impeller 2, the hot and humid gas enters the duct 3 from the steam inlet space 1A under centrifugal force, forming flowing water droplets on the inner wall 6. As it flows through the first part of the inner wall 61, it enters the drainage channel 7A through the dehydration port 611, thus forming a primary water-vapor separation. For hot and humid gas with low moisture content, the primary water-vapor separation structure 4 near the steam inlet space 1A in the duct 3 can largely separate the moisture. However, the size of the dehydration port 611 on the first part of the inner wall 61 is limited to prevent air leakage, thus limiting the amount of moisture separated by the primary water-vapor separation structure 4. When the moisture content in the hot and humid gas is high, the primary water-vapor separation structure 4 cannot completely separate the moisture. Therefore, a secondary water-vapor separation structure 5 near the outlet 12 in the duct 3 is needed for secondary water-vapor separation. When the moisture content in the hot and humid gas is high, the water droplets form a thin, flowing water film on the inner wall 6, which can be continuously discharged from the dehydration port 611 into the drainage channel 7A.

[0056] The air duct 3 extends in a linear shape. The hot and humid gas flows from one end connected to the centrifugal diffusion space to the other end connected to the outlet 12 in the air duct 3. Under normal circumstances, in order to improve the water vapor separation effect, the air duct 3 will be equipped with multiple primary water vapor separation structures 4 and arranged along the flow path of the hot and humid gas. Multiple water vapor separation structures perform multiple and sufficient primary water vapor separation on the hot and humid gas. The air duct 3, which extends in a linear shape and has a narrow structure, can support this primary water vapor separation mechanism.

[0057] In this embodiment, a primary water vapor separation structure 4 is provided at the bend 3-1 of the air duct 3. The bend 3-1 can change the flow direction of the hot and humid gas, and when the flow direction changes, the primary water vapor separation structure 4 performs secondary water vapor separation, thus achieving a better water vapor separation effect.

[0058] In addition, a primary water vapor separation structure 4 is provided at the bend 3-1 corresponding to the duct wall 31 with a larger turning radius. When the hot and humid gas turns through the bend 3-1, the water droplets contained in it can be formed into a state that is approximately thrown onto the duct wall 31 with a larger turning radius under the action of mass inertia. Compared with the inner wall 6 with a smaller turning radius, the amount of water droplets on the inner wall 6 with a larger turning radius is larger, which makes the water vapor separation amount of the primary water vapor separation structure 4 at this location greater and the water vapor separation effect better.

[0059] In this embodiment, the extension direction of the air duct 3 connecting the steam inlet space 1A is set along the tangential direction of the impeller 2. Since the outflow direction of the hot and humid gas from the steam inlet space 1A is along the tangential direction of the impeller 2, the air intake rate of the air duct 3 can be improved.

[0060] Furthermore, a primary water vapor separation structure 4 is provided at the section of the air duct 3 connected to the steam inlet space 1A, away from the impeller 2, on the duct wall 31. Under centrifugal force, the water droplets formed on the inner wall 6 away from the impeller 2 by the humid and hot gas are larger. Therefore, the inner wall away from the impeller 2 is the first part of the inner wall 61, and the first water vapor separation structure provided at this location can have a better water vapor separation effect.

[0061] In this embodiment, the first-stage water vapor separation structure 4, due to the water vapor separation mechanism of the dehydration port 611, should not have too many dehydration ports 611, so as to avoid insufficient output of dry hot air from the outlet 12 due to air leakage. In this embodiment, the layout of the first-stage water vapor separation structure 4 in the air duct 3 can maximize the effect of the first-stage water vapor separation.

[0062] In this embodiment, the secondary water vapor separation structure 5 includes a guide rail 51 with a gap to the inner wall 6, and a second inner wall 62 on the inner wall 6 corresponding to the guide rail 51. A drainage branch 7B is defined between the guide rail 51 and the second inner wall 62. The second inner wall 62 has a drainage connection port 7D connecting the drainage branch 7B and the drainage channel 7A. The guide rail 51 can be independently installed in the air duct 3, or it can be formed by branches generated from the inner wall 6.

[0063] The gap between the guide rail 51 and the first inner wall 61 should not be too large to avoid air leakage. When the gap is small, the drainage capacity of the secondary water vapor separation structure 5 also has an upper limit. Therefore, under normal circumstances, when hot and humid gas flows in the duct 3, most of the water droplets flowing on the inner wall 6 are separated through the dewatering port 611. The remaining water droplets, when passing through the secondary water vapor separation structure 5, are isolated by the guide rail 51 and enter the drainage branch 7B under the guidance of the guide rail 51. Then, they enter the drainage channel 7A through the drainage connector 7D, forming a secondary water vapor separation. The drainage connector 7D is located downstream of the second inner wall 62, allowing the drainage branch 7B to be fully utilized. If the hot and humid gas has a high water content, a flowing water film forms on the inner wall 6. After the primary water vapor separation by the primary water vapor separation structure 4, the thickness of the flowing water film is relatively thin. Even with a small gap between the guide rail 51 and the first inner wall 61, all the water droplets can enter the drainage branch 7B for relatively thorough water vapor separation.

[0064] In practical applications, the water vapor separator can continuously separate water vapor from the humid and hot gas in the inner tank environment. When the water vapor separator is initially started, if the inner tank environment is very humid, the hot gas output by the water vapor separator will still contain a certain amount of moisture in the initial stage. However, based on the internal circulation airflow mechanism constructed by the water vapor separator, under the condition of completely eliminating external interference, the moisture content of the humid and hot gas entering the steam inlet 11 gradually decreases until the hot gas output from the outlet 12 is basically free of moisture.

[0065] In this embodiment, a drainage guide channel 7C that crosses the air duct 3 connects the two drainage channels 7A. Based on the setting of the bend 3-1 of the air duct 3 and the position layout of the primary water vapor separation structure 4, the water flow of the two drainage channels 7A is different. By setting the drainage guide channel 7C, the flow can be guided to balance the drainage volume of the two drainage channels 7A.

[0066] In this embodiment, the housing 1 is provided with drain outlets 13, and the number of drain outlets 13 is unlimited. Each drain outlet 13 is connected to one of the drainage channels 7A. Since the two drainage channels 7A are connected through the drainage guide channel 7C, the drain outlet 13 only needs to be connected to one of the drainage channels 7A to discharge all the water separated by the primary water vapor separation structure 4 and the secondary water vapor separation structure 5. The drain outlet 13 can be configured as a trough-shaped structure or a perforated structure.

[0067] In this embodiment, the steam inlet 11 and the steam outlet 12 are located on the same shell surface of the shell 1 and face the internal environment of the inner liner.

[0068] In one embodiment, two air ducts 3 are provided and are mirror-symmetrical about the impeller 2. In this embodiment, the two air ducts 3 are positioned one above the other on the housing 1, corresponding to the air outlets 12, which can expand the coverage area of ​​the output dry hot air and enhance the drying effect on the internal environment. In this embodiment, since the number of air ducts 3 is relatively small, the width of the air ducts 3 should not be too narrow, and the number of primary water vapor separation structures 4 should not be too small.

[0069] In other embodiments, three or more air ducts 3 are arranged at intervals along the circumference of the impeller 2. In these embodiments, the number of air outlets 12 is greater, and the output of dry hot air is more uniform. In these embodiments, the width of the air ducts 3 can be slightly narrower, and the number of primary water vapor separation structures 4 can be reduced.

[0070] Implementation Case 2:

[0071] Referring to Figure 5, a dishwasher inner tub includes an inner tub and at least one water vapor separation device J. The number of water vapor separation devices J needs to be reasonably set according to the actual drying needs. The water vapor separation device J is shown in Embodiment 2.

[0072] In this embodiment, the water vapor separator J is installed on the inner wall K of the inner liner.

[0073] In this embodiment, a cover L is provided on the inner liner, and a water vapor separator J is installed inside the cover L. A drain trough LA is provided at the bottom of the cover L. The water separated by the water vapor separator J is discharged from the outer shell L through the drain outlet 13 and also discharged from the cover L through the drain trough 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.

[0074] In this embodiment, the casing L includes a receiving groove L1 and an inner liner cover L2. The receiving groove L1 is formed by a recess in the inner liner wall K, and the inner liner cover L2 seals the receiving groove L1. Additionally, the casing L has openings at both the steam inlet 11 and the steam outlet 12 for inputting humid hot gas and outputting dry hot gas. The inner liner cover L2 can be fixedly connected to the inner liner wall K with fasteners, facilitating disassembly and installation.

[0075] Implementation Case 3:

[0076] A dishwasher has a dishwasher inner liner, as shown in Embodiment 2.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
