Abstract
Description
Technical Field
[0001] This application relates to kitchen appliance technology. In particular, it relates to a dishwasher. Background Technology
[0002] As living standards improve, people have higher and higher requirements for quality of life, and dishwashers have become increasingly common in people's lives in recent years.
[0003] In related technologies, dishwashers include an inner tub, a fan, and a breather, with the fan and breather connected to the inner tub. Dishwasher washing consists of four stages: main wash, cold rinse, hot rinse, and drying. After the high-temperature rinse, a large amount of water vapor is generated in the inner tub due to the high temperature. When the fan starts and delivers hot air into the inner tub, a large amount of hot steam is expelled through the breather.
[0004] However, water droplets easily condense on the outside of the dishwasher, and drying takes a long time. Summary of the Invention
[0005] This application provides a dishwasher that is less prone to condensation on its exterior and has a shorter drying time.
[0006] To achieve the above objectives, this application adopts the following technical solution:
[0007] This application provides a dishwasher, comprising:
[0008] The outer casing has a mounting cavity.
[0009] The inner liner is located inside the installation cavity and has a cleaning chamber.
[0010] The door is movably connected to the outer casing to open or close the cleaning chamber;
[0011] The fan assembly is located inside the mounting cavity and is connected to the inner liner;
[0012] A respirator, located within the mounting cavity and connected to the inner liner;
[0013] The air duct structure is set inside the installation cavity and is connected to the fan assembly. The air duct structure has an air duct cavity and a ventilation opening, which is connected to the air duct cavity.
[0014] The fan assembly is configured to blow hot air into the cleaning chamber and to blow hot air to the outside of the inner liner through the air duct chamber and vent.
[0015] In this way, during the drying mode, the fan assembly blows hot air outwards, raising the temperature of the dishwasher's outer walls and surrounding objects. This reduces the temperature difference between the dishwasher's outer walls and surrounding objects and the air exhausted from the respirator, making it less prone to condensation in the exhaust air. The fan assembly also accelerates the evaporation of moisture within the cleaning chamber by blowing hot air into it, speeding up the drying process. Furthermore, compared to similar technologies, the cooling time for the inner drum can be eliminated or reduced, thus helping to decrease the dishwasher's operating time and reduce energy consumption.
[0016] In some embodiments, the air duct structure includes:
[0017] The air supply duct has an air duct cavity and multiple ventilation openings. The multiple ventilation openings are spaced apart along the extension direction of the air supply duct and are connected to the fan assembly.
[0018] A control valve is connected to a fan assembly or to an air supply duct, and is configured to control whether the fan assembly is connected to or not connected to the air supply duct.
[0019] In this way, in some cases, the fan can provide airflow only to the inner tank without providing airflow to the air supply duct, thereby reducing energy consumption.
[0020] In some embodiments, the vent is located on the side of the air supply duct away from the inner liner;
[0021] And / or, the vent is located on the side of the air supply duct facing the door.
[0022] In this way, the vents direct hot air towards the perimeter of the dishwasher, which helps to raise the temperature of the dishwasher's exterior walls and surrounding objects. And / or, it helps the hot air blown out of the duct to blow the air exhausted from the respirator to the outside of the cabinet, making it less likely for condensation to form inside the cabinet due to steam buildup.
[0023] In some embodiments, a partition is provided in the air supply duct, and the air duct cavity of the partition is divided into at least two regions, the at least two regions including a first region and a second region, with some vents communicating with the first region and some vents communicating with the second region.
[0024] Some of the hot air flows to the outside of the inner liner through the first zone and the vents connected to the first zone;
[0025] Some of the hot air flows to the outside of the inner liner through the second zone and the vents connected to the second zone.
[0026] In this way, by setting up separators, it is easier to control the air volume of the ventilation openings at different locations.
[0027] In some embodiments, the air supply duct is disposed on the outer wall of the inner liner, and a portion of the air supply duct is adjacent to the door along the depth direction of the inner liner.
[0028] In this way, the air supply duct is positioned close to the door, making it easier for the hot air blown out of the duct to blow the air exhausted by the respirator to the outside of the cabinet or to a location with better air circulation.
[0029] In some embodiments, the air supply duct includes:
[0030] The first air supply duct is connected to the fan assembly;
[0031] The second air supply duct is connected to the first air supply duct. The second air supply duct is located on one side of the inner liner along the width direction and is equipped with a vent.
[0032] The third air supply duct is connected to the second air supply duct. The third air supply duct is located at the top of the inner liner and is equipped with a vent.
[0033] The fourth air supply duct is connected to the third air supply duct. The fourth air supply duct is located on the other side of the inner liner along the width direction and is equipped with a ventilation opening.
[0034] The inner cavities of the first, second, third, and fourth air supply pipes form an air duct cavity.
[0035] By setting up a first air supply pipe, a second air supply pipe, a third air supply pipe, and a fourth air supply pipe, wherein the second, third, and fourth air supply pipes are arranged around the top of the inner tank and on both sides along the width direction, and the second, third, and fourth air supply pipes are provided with ventilation openings, the air supply pipes can deliver hot air to a larger area, which is beneficial to increasing the temperature of the outer wall of the dishwasher and surrounding objects.
[0036] In some embodiments, the system also includes a column, the outer wall of which is provided with a receiving cavity, the column being connected to the outer wall of the inner liner, and the edge of the column facing the door being flush with the edge of the inner liner facing the door.
[0037] The second, third, and fourth air supply pipes are located inside the receiving cavity.
[0038] In this way, the second, third, and fourth air ducts do not require additional space, which helps to reduce the overall size of the dishwasher. Moreover, the second, third, and fourth air ducts are located close to the door, making it easier for the hot air blown out by the second, third, and fourth air ducts to blow the air exhausted by the respirator to the outside of the cabinet or to a location with better air circulation.
[0039] In some embodiments, the first air supply duct is plugged into the fan assembly;
[0040] The second air supply pipe is connected to the first air supply pipe;
[0041] The third air supply pipe is connected to the second air supply pipe;
[0042] The fourth air supply duct is connected to the third air supply duct.
[0043] This makes the fabrication of the air supply duct less difficult.
[0044] In some embodiments, the number of separators is at least two, and the at least two separators include:
[0045] A first partition is located inside a second air supply duct to divide the inner cavity of the second air supply duct into a first region and a second region, and the vent on the second air supply duct is connected to the first region.
[0046] The second partition is located inside the third air supply duct to divide the inner cavity of the third air supply duct into a third region and a fourth region. The vent on the third air supply duct is connected to the third region. The third region is connected to the first region and also to the second region. The fourth region is connected to the first region and also to the second region.
[0047] The inner cavity of the fourth air supply duct is connected to the third area and also to the fourth area.
[0048] In this way, by setting the first and second partitions to distribute the air volume, it is beneficial to improve the uniformity of the air output from the second, third and fourth air supply ducts.
[0049] In some embodiments, the wind turbine assembly includes:
[0050] The fan is located at the bottom of the inner liner;
[0051] The fan cover has an air supply chamber, is connected to the fan, and is also connected to the inner liner. The control valve is configured to control whether the fan cover is connected to or not connected to the air supply pipe.
[0052] By installing a fan cover, the fan's placement can be more flexible. The fan can be positioned below the inner liner, which facilitates the upward movement of hot air into the inner liner when the fan delivers it. Attached Figure Description

[0079] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0080] In related technologies, dishwashers include an inner tub, a fan, and a breather, both of which are connected to the inner tub. Dishwasher washing consists of four stages: main wash, cold rinse, hot rinse, and drying. After the high-temperature rinse, a large amount of water vapor is generated in the inner tub due to the high temperature. When the fan starts and delivers hot air into the inner tub, a large amount of hot steam is expelled through the breather. When the hot steam encounters the outer wall of the dishwasher and the surrounding cabinet, it condenses into water droplets due to the significant temperature difference, producing condensation.
[0081] Currently, methods typically involve lowering the temperature of the dishwasher's inner drum to reduce the amount of steam inside and minimize the temperature difference between the air exhausted from the exhaust fan and the dishwasher's outer walls and surrounding cabinetry. For example, the dishwasher may be paused for a period after the hot-drying phase. Alternatively, after the hot-drying phase, the fan may supply cold air to the inner drum. Another method is to use an alternating cycle of hot and cold air during the drying process. Combining these three methods lowers the temperature of the dishwasher's inner drum, thereby reducing the amount of hot steam. This method increases the dishwasher's drying time.
[0082] For example, after the heat dissipation is complete, pause for T1 minutes. Then start the fan to deliver cold air into the inner tank. After a certain period of time, pause for T2 minutes. Then start the fan again to blow cold air, and repeat the operation for N1 cycles. Finally, start the fan to deliver hot air and cold air into the inner tank alternately, and after a certain period of time, pause for T3 minutes, and repeat the operation for N2 cycles.
[0083] Based on this, hot steam condenses into water when it encounters a cold surface, but it is less likely to condense into water when it comes into contact with a hot object. To overcome the shortcomings of related technologies, the dishwasher provided in this application blows hot air to the outside of the inner drum during the drying process using a fan assembly and air duct structure. This increases the temperature of the outer wall of the dishwasher and surrounding objects, reducing the temperature difference and making it less likely for hot steam to condense into water. Furthermore, because the temperature of the outer wall of the dishwasher and surrounding objects is increased, the temperature drop of the inner drum can be reduced or cooling of the inner drum can be eliminated, thereby reducing the cooling time of the inner drum and the working time of the dishwasher during drying.
[0084] For example, after the hot air bleaching program is completed, there is no need to pause the program to cool the inner drum. After the hot air bleaching program is completed, hot air can be directly delivered into the inner drum of the dishwasher for drying.
[0085] Alternatively, the pause time can be reduced after the hot drift ends, for example, by reducing T4 minutes.
[0086] Alternatively, reduce the cooling air circulation cycle. For example, reduce it by N3 cycles.
[0087] Alternatively, the pause time for cold air can be reduced, for example, by reducing the pause time to T5 minutes.
[0088] Alternatively, the hot and cold air circulation cycle can be reduced, for example, by reducing the number of cycles by N4.
[0089] Alternatively, reduce the pause time for hot and cold air, for example, reduce T6 minutes.
[0090] This technology can effectively reduce the working time of dishwashers, which helps to reduce energy consumption and improve the user experience for consumers.
[0091] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.
[0092] This application provides a dishwasher, which can be a built-in dishwasher, a freestanding dishwasher, or a countertop dishwasher.
[0093] Figure 1 This is a schematic diagram of the structure of a dishwasher provided in an embodiment of this application.
[0094] See Figure 1 As shown, in some embodiments, the dishwasher includes a housing 100. The housing 100 is provided with a mounting cavity.
[0095] Figure 2 This is a schematic diagram of the inner tank, fan assembly, and air duct structure of a dishwasher provided in an embodiment of this application. Figure 3 for Figure 2 A structural diagram from another angle.
[0096] See Figure 2 and Figure 3 As shown, in some embodiments, the dishwasher includes an inner tank 200. The inner tank 200 is located within an installation cavity and has a cleaning chamber.
[0097] See Figure 1 As shown, in some embodiments, the dishwasher includes a door 300. The door 300 is movably connected to the housing 100 to open or close the cleaning chamber.
[0098] In some embodiments, the dishwasher includes a dish rack. The dish rack is disposed within the cleaning chamber and is slidably connected to the inner liner 200.
[0099] In some embodiments, the dishwasher includes a water supply system for communication with an external water source.
[0100] In some embodiments, the dishwasher includes a spray arm disposed within and rotatably connected to the inner tub 200. A water supply system is connected to the spray arm, which sprays liquid onto the dishes inside the cleaning chamber.
[0101] See Figure 2 and Figure 3 As shown, in some embodiments, the dishwasher includes a fan assembly 400. The fan assembly 400 can deliver hot or cold air into the inner tank 200. The fan assembly 400 is located within the mounting cavity and communicates with the inner tank 200.
[0102] In some embodiments, the dishwasher includes a breather. The breather is used to vent air from the inner tank 200 to the outside of the dishwasher. The breather is located within a mounting cavity and communicates with the inner tank 200.
[0103] During the drying process, the warm and humid air inside the dishwasher 200 is released to the outside of the dishwasher through a breather. When this warm and humid air comes into contact with the outer wall of the dishwasher or an external cabinet, the large temperature difference causes condensation to form.
[0104] To address the aforementioned technical issues and reduce the temperature difference between the air exhausted from the respirator into the dishwasher and the dishwasher's outer wall or external cabinet, see [link to relevant documentation]. Figure 2 and Figure 3 As shown, in some embodiments, the dishwasher includes an air duct structure 500.
[0105] The air duct structure 500 is installed inside the mounting cavity and is connected to the fan assembly 400.
[0106] The air duct structure 500 is provided with an air duct cavity and an air vent 510, which is connected to the air duct cavity.
[0107] In some embodiments, the number of vents 510 may be one, two, or more.
[0108] The fan assembly 400 is configured to blow hot air into the cleaning chamber and to blow hot air to the outside of the inner liner 200 through the air duct chamber and the vent 510.
[0109] Understandably, during the drying mode, the fan assembly 400 blows hot air outwards to raise the temperature of the dishwasher's outer walls and surrounding objects, reducing the temperature difference between the dishwasher's outer walls and surrounding objects and the air exhausted from the respirator, thus preventing condensation in the exhaust air. The fan assembly 400 also accelerates the evaporation of moisture within the cleaning chamber by blowing hot air into it, speeding up drying. Furthermore, compared to related technologies, the cooling time for the inner tank 200 can be eliminated or reduced, thus helping to decrease the dishwasher's operating time and reduce energy consumption.
[0110] Figure 4 This is a schematic diagram of the structure of the inner tank of a dishwasher provided in an embodiment of this application.
[0111] See Figure 4 As shown, in some embodiments, the side wall of the inner liner 200 is provided with a first communication port 210, which communicates with the cleaning chamber. The respirator communicates with the inner liner 200 through the first communication port 210. Air from the cleaning chamber enters the respirator through the first communication port 210.
[0112] In some embodiments, the inner liner 200 has a second communication port 220 on its side wall, which communicates with the cleaning chamber. The fan assembly 400 communicates with the inner liner 200 through the second communication port 220. Hot or cold air from the fan assembly 400 enters the cleaning chamber through the second communication port 220.
[0113] In some embodiments, the first connecting port 210 and the second connecting port 220 are arranged opposite to each other. This facilitates faster airflow within the inner liner 200.
[0114] Specifically, the first connecting port 210 and the second connecting port 220 are located on opposite sides of the inner liner 200 along the width direction.
[0115] Figure 5 This is a schematic diagram of the structure of the fan assembly in the dishwasher provided in an embodiment of this application.
[0116] See Figure 5 As shown, in some embodiments, the fan assembly 400 includes a fan 410. The fan 410 is used to deliver hot or cold air.
[0117] See Figure 2 and Figure 3 As shown, in some embodiments, the fan 410 is positioned below the inner liner 200.
[0118] In some embodiments, the fan 410 may be installed on the inner liner 200, and the fan 410 is connected to the second communication port 220.
[0119] See Figure 5 As shown, in some embodiments, the fan assembly 400 includes a fan cover 420. The fan cover 420 provides a flow path for the air output from the fan 410.
[0120] The fan cover 420 is provided with an air supply chamber. The fan cover 420 is connected to the fan 410 and the inner liner 200. Hot or cold air output by the fan 410 enters the inner liner 200 through the air supply chamber and the second connecting port 220.
[0121] Understandably, by setting the fan cover 420, the placement of the fan 410 can be more flexible. The fan 410 can be positioned below the inner liner 200, which facilitates the rising of hot air into the inner liner 200 when the fan 410 delivers hot air.
[0122] Figure 6 for Figure 5 Another structural diagram from another angle.
[0123] See Figure 6 As shown, in some embodiments, the fan cover 420 includes a first fan cover 421.
[0124] The first fan cover 421 is provided with a first air supply chamber. The fan 410 is located inside the first air supply chamber.
[0125] See Figure 5 and Figure 6 As shown, in some embodiments, the fan cover 420 includes a second fan cover 422.
[0126] The second fan cover 422 is connected to the first fan cover 421. In some embodiments, the second fan cover 422 is located on top of the first fan cover 421.
[0127] In some embodiments, the second fan cover 422 is detachably connected to the first fan cover 421. For example, the connection can be made by clips or screws. This reduces the difficulty of manufacturing.
[0128] In some embodiments, the second fan cover 422 is integrally formed with the first fan cover 421. This reduces the number of installation steps.
[0129] In some embodiments, the second fan cover 422 is provided with a second air supply cavity, which is connected to the first air supply cavity and is connected to the second communication port 220.
[0130] In some embodiments, the second fan cover 422 is provided with a third connecting port 4221, which communicates with the second air supply chamber and is also connected to the second connecting port 220. The third connecting port 4221 and the second connecting port 220 are opposite each other. In this way, the air delivered by the fan 410 can enter the second connecting port 220 through the third connecting port 4221, thereby increasing the airflow speed.
[0131] In some embodiments, the third connection port 4221 matches the shape of the second connection port 220. For example, the third connection port 4221 and the second connection port 220 are circular and have the same opening size. The axis of the third connection port 4221 is collinear with the axis of the second connection port 220.
[0132] In some embodiments, a second fan cover 422 is disposed on the side wall of the inner liner 200. A sealing element is provided between the second fan cover 422 and the side wall of the inner liner 200. The sealing element abuts against the second fan cover 422 and against the outer wall of the inner liner 200.
[0133] See Figure 5 and Figure 6 As shown, in some embodiments, the fan cover 420 includes a third fan cover 423.
[0134] The third fan cover 423 is connected to the second fan cover 422.
[0135] In some embodiments, the third fan cover 423 is located on top of the second fan cover 422.
[0136] In some embodiments, the third fan cover 423 is detachably connected to the second fan cover 422. For example, the connection can be made by clips or screws. This reduces the difficulty of manufacturing.
[0137] In some embodiments, the third fan cover 423 is integrally formed with the second fan cover 422. This reduces the number of installation steps.
[0138] In some embodiments, the third fan cover 423 is provided with a third air supply chamber 4232, which is connected to the second air supply chamber.
[0139] Figure 7 This is a schematic diagram of the fan assembly structure and air duct structure in the dishwasher provided in the embodiments of this application.
[0140] See Figure 7 As shown, in some embodiments, the air duct structure 500 includes an air supply duct 520.
[0141] The air supply duct 520 is provided with an air duct cavity and multiple ventilation openings 510 are provided in the air supply duct 520. The multiple ventilation openings 510 are spaced apart along the extension direction of the air supply duct 520.
[0142] In some embodiments, the air supply duct 520 is connected to the fan assembly 400.
[0143] Specifically, the air supply duct 520 can be connected to the third fan cover 423.
[0144] In some embodiments, the air supply duct 520 may be plugged into the third fan cover 423.
[0145] In some embodiments, a sealing element is provided between the outer wall of the air supply duct 520 and the inner wall of the third fan cover 423. The sealing element is interference-fitted with the third fan cover 423.
[0146] In some embodiments, the outer wall of the air supply duct 520 is provided with an assembly cavity, and the sealing element is disposed in the assembly cavity.
[0147] In some embodiments, the duct structure 500 includes a control valve 530.
[0148] The control valve 530 is configured to control whether the fan assembly 400 is connected to or not connected to the duct structure 500.
[0149] In some embodiments, the control valve 530 is connected to the fan assembly 400 or to the air supply duct 520, and the control valve 530 is configured to control whether the fan assembly 400 is connected to or not connected to the air supply duct 520.
[0150] Figure 8 This is a schematic diagram of the structure of the third fan cover and control valve in the dishwasher provided in an embodiment of this application. Figure 9 for Figure 8 A cross-sectional view along the AA direction.
[0151] See Figure 8 and Figure 9 As shown, in some embodiments, a control valve 530 is disposed on a fan cover plate 420, and the control valve 530 is configured to control whether the fan cover plate 420 is connected to or not connected to the air supply pipe 520.
[0152] In some embodiments, the third fan cover 423 is provided with a fourth air supply chamber 4233. The third fan cover 423 is provided with a fourth connecting port 4231, which connects the fourth air supply chamber 4233 and the third air supply chamber 4232. The air supply duct 520 is connected to the fourth air supply chamber 4233.
[0153] The control valve 530 is inserted into the fourth connection port 4231 so that the fourth air supply chamber 4233 and the third air supply chamber 4232 can be connected or disconnected.
[0154] In some embodiments, a seal is provided between the outer wall of the control valve 530 and the inner wall of the fourth communication port 4231. The seal forms an interference fit with the third air cover.
[0155] In some embodiments, the control valve 530 can be a solenoid valve. The opening and closing of the air supply pipe 520 is controlled by whether the solenoid valve is energized or not, so as to determine whether hot air enters the air supply pipe 520.
[0156] Figure 9 The diagram shows the state when the solenoid valve is energized. When energized, the coil generates electromagnetic force, causing the magnetic core to overcome the spring force and move away from the third air supply chamber 4232, opening the exhaust passage. At this time, the hot air generated by the fan 410 can enter the air supply pipe 520 through the fan pipe. When the solenoid valve is de-energized, due to the spring force, the valve core moves towards the third air supply chamber 4232, closing the fourth connecting port 4231. In this state, the hot air generated by the fan 410 can only enter the inner liner 200 through the fan cover.
[0157] See Figure 2 As shown, in some embodiments, the air supply duct 520 is disposed on the outer wall of the inner liner 200.
[0158] In some embodiments, along the depth direction of the inner liner 200, a portion of the air supply duct 520 is adjacent to the door 300. This proximity of the air supply duct 520 to the door 300 facilitates the hot air blown from the air supply duct 520 to direct the air exhausted by the respirator to the outside of the cabinet or to a location with better air circulation.
[0159] In some embodiments, the vent 510 is located on the side of the air duct 520 away from the inner tank 200. In this way, hot air can be directed towards the periphery of the dishwasher through the vent 510, which helps to increase the temperature of the outer wall of the dishwasher and surrounding objects.
[0160] In some embodiments, the vent 510 is located on the side of the air supply duct 520 facing the door 300. This facilitates the hot air blown out of the air supply duct 520 to blow the air exhausted by the respirator to the outside of the cabinet, or to a location with better air circulation, thereby reducing the amount of hot steam accumulation and condensation.
[0161] In some embodiments, the vent 510 is located on the side of the air supply duct 520 away from the door body 300.
[0162] In some embodiments, some vents 510 are located on the side of the air supply duct 520 facing the door 300, and some vents 510 are located on the side of the air supply duct 520 away from the door 300. In this way, the air supply duct 520 can blow air in two directions, improving the uniformity of temperature rise of the dishwasher's outer wall and surrounding objects.
[0163] In some embodiments, some vents 510 are located on the side of the air duct 520 away from the inner tank 200. Some vents 510 are located on the side of the air duct 520 facing the door 300. This is beneficial for both increasing the temperature of the outer wall of the dishwasher and surrounding objects, and for the hot air blown out of the air duct 520 to blow the air exhausted by the breather to the outside of the cabinet, making it less likely for condensation to form inside the cabinet due to steam accumulation.
[0164] It should be noted that the position and size of the vent 510 can be designed according to the actual working conditions of the dishwasher. In areas where condensation is prone to form, the distance between two adjacent vents 510 can be reduced and the size of the vent 510 can be increased to improve the hot air delivery rate. In areas where condensation is not prone to form, the distance between two adjacent vents 510 can be increased.

[0166] See Figure 10 and Figure 11 As shown, in some embodiments, the air supply duct 520 includes a first air supply duct 521.
[0167] The first air supply duct 521 is connected to the fan assembly 400.
[0168] Specifically, the first air supply duct 521 can be connected to the third fan cover 423.
[0169] In some embodiments, the first air supply duct 521 can be a circular duct. Alternatively, the first air supply duct 521 can be a rectangular duct.
[0170] Figure 12 This is a schematic diagram of the structure of the second air duct in the dishwasher provided in an embodiment of this application.
[0171] See Figure 10 and Figure 12 As shown, in some embodiments, the air supply duct 520 includes a second air supply duct 522.
[0172] The second air supply pipe 522 is connected to the first air supply pipe 521. The second air supply pipe 522 is located on one side of the inner liner 200 along the width direction, and the second air supply pipe 522 is provided with a vent 510.
[0173] In some embodiments, a vent 510 is provided on the side of the second air supply duct 522 away from the door body.
[0174] In some embodiments, the first air supply duct 521 and the second air supply duct 522 are detachably connected. This reduces the difficulty of processing.
[0175] In some embodiments, the first air supply pipe 521 and the second air supply pipe 522 are inserted into each other. Alternatively, in some embodiments, the first air supply pipe 521 and the second air supply pipe 522 are connected by a snap-fit.
[0176] In some embodiments, a sealing element is provided between the outer wall of the first air supply duct 521 and the inner wall of the second air supply duct 522.
[0177] In some embodiments, the first air supply duct 521 and the second air supply duct 522 are integrally formed. This reduces installation steps and improves installation efficiency.
[0178] Figure 13 This is a schematic diagram of the structure of the third air duct in the dishwasher provided in an embodiment of this application.
[0179] See Figure 10 and Figure 13 As shown, in some embodiments, the air supply duct 520 includes a third air supply duct 523.
[0180] The third air supply pipe 523 is connected to the second air supply pipe 522. The third air supply pipe 523 is located at the top of the inner liner 200 and is provided with a vent 510.
[0181] In some embodiments, a vent 510 is provided on the side of the third air supply duct 523 facing the door 300.
[0182] In some embodiments, the second air supply duct 522 and the third air supply duct 523 are detachably connected. This reduces the difficulty of manufacturing.
[0183] In some embodiments, the second air supply duct 522 and the third air supply duct 523 are inserted into each other. Alternatively, in some embodiments, the second air supply duct 522 and the third air supply duct 523 are connected by a snap-fit.
[0184] In some embodiments, a seal is provided between the outer wall of the second air supply duct 522 and the inner wall of the third air supply duct 523.
[0185] In some embodiments, the second air supply duct 522 and the third air supply duct 523 are integrally formed. This reduces installation steps and improves installation efficiency.
[0186] Figure 14 This is a schematic diagram of the structure of the fourth air duct in the dishwasher provided in an embodiment of this application.
[0187] See Figure 10 and Figure 14 As shown, in some embodiments, the air supply duct 520 includes a fourth air supply duct 524.
[0188] The fourth air supply pipe 524 is connected to the third air supply pipe 523. The fourth air supply pipe 524 is located on the other side of the inner liner 200 along the width direction. The fourth air supply pipe 524 is provided with a vent 510.
[0189] In some embodiments, a vent 510 is provided on the side of the fourth air supply duct 524 facing the door 300.
[0190] In some embodiments, the fourth air supply duct 524 is detachably connected to the third air supply duct 523. This reduces the difficulty of manufacturing.
[0191] In some embodiments, the fourth air supply duct 524 is inserted into the third air supply duct 523. Alternatively, in some embodiments, the second air supply duct 522 and the third air supply duct 523 are connected by a snap-fit.
[0192] In some embodiments, a seal is provided between the outer wall of the third air supply duct 523 and the inner wall of the fourth air supply duct 524.
[0193] In some embodiments, the fourth air supply duct 524 is integrally formed with the third air supply duct 523. This reduces installation steps and improves installation efficiency.
[0194] In some embodiments, the inner cavities of the first air supply pipe 521, the second air supply pipe 522, the third air supply pipe 523, and the fourth air supply pipe 524 form an air duct cavity.
[0195] It is understandable that by setting up a first air supply pipe 521, a second air supply pipe 522, a third air supply pipe 523, and a fourth air supply pipe 524, wherein the second air supply pipe 522, the third air supply pipe 523, and the fourth air supply pipe 524 are arranged around the top of the inner liner 200 and on both sides along the width direction, and the second air supply pipe 522, the third air supply pipe 523, and the fourth air supply pipe 524 are provided with ventilation openings 510, so that the air supply pipes can deliver hot air to a larger area, which is beneficial to increasing the temperature of the outer wall of the dishwasher and surrounding objects.
[0196] In some embodiments, the dishwasher also includes a column 600.
[0197] The outer wall of the column 600 is provided with a receiving cavity. The column 600 is connected to the outer wall of the inner liner 200. The edge of the column 600 facing the door 300 is flush with the edge of the inner liner 200 facing the door 300.
[0198] The second air supply duct 522, the third air supply duct 523, and the fourth air supply duct 524 are located within the receiving cavity. This eliminates the need for additional space occupied by these ducts, reducing the overall size of the dishwasher. Furthermore, their proximity to the door 300 facilitates the direct flow of hot air from these ducts to the outside of the cabinet or to areas with better air circulation.
[0199] Figure 15 Cross-sectional views of the second, third, and fourth air supply pipes in the dishwasher provided in this application embodiment.
[0200] See Figure 15 As shown, the hot air generated by the fan 410 will lose airflow after passing through the vent 510. To effectively prevent excessive loss of hot air during the delivery process due to the excessive length of the air supply duct 520, which would affect the amount of hot air delivered to the end of the air supply duct 520 and thus affect the condensation elimination effect, in some embodiments, a separator 540 is provided inside the air supply duct 520.
[0201] The partition 540 divides the air duct cavity into at least two regions, including a first region and a second region. Part of the vent 510 is connected to the first region, and part of the vent 510 is connected to the second region.
[0202] Some of the hot air flows to the outside of the inner liner 200 through the first zone and the vent 510 connected to the first zone.
[0203] Some of the hot air flows to the outside of the inner liner 200 through the second zone and the vent 510 connected to the second zone.
[0204] Understandably, setting up the separator 540 helps to control the air volume of the vents 510 at different locations.
[0205] In some embodiments, the separator 540 may be a partition plate. The partition plate is detachably connected to the air supply duct 520.
[0206] In some embodiments, the separator 540 may be a sealing rib. The separator 540 is integrally formed with the air supply duct 520.
[0207] In some embodiments, the number of separators 540 is at least two.
[0208] Figure 16 for Figure 12 A sectional view along the BB direction. Figure 17 for Figure 13 A sectional view along the CC direction. Figure 18 for Figure 14 A sectional view along the DD direction.
[0209] See Figures 16 to 18 As shown, in some embodiments, at least two separators 540 include a first separator 541.
[0210] The first partition 541 is located in the second air supply duct 522 to divide the inner cavity of the second air supply duct 522 into a first region and a second region, and the vent 510 on the second air supply duct 522 is connected to the first region.
[0211] In some embodiments, at least two separators 540 include a second separator 542.
[0212] The second partition 542 is located inside the third air supply duct 523 to divide the inner cavity of the third air supply duct 523 into a third region and a fourth region. The vent 510 on the third air supply duct 523 is connected to the third region. The third region is connected to the first region and also to the second region. The fourth region is connected to the first region and also to the second region.
[0213] The inner cavity of the fourth air supply duct 524 is connected to the third area and also to the fourth area.
[0214] It is understandable that by setting the first separator 541 and the second separator 542 to distribute the air volume, it is beneficial to improve the uniformity of the air output from the second air supply duct 522, the third air supply duct 523 and the fourth air supply duct 524.
[0215] In some embodiments, a third separator 543 is also included.
[0216] The third partition 543 is located inside the fourth air supply duct 524 to divide the inner cavity of the fourth air supply duct 524 into a fifth region and a sixth region. The vent 510 of the fourth air supply duct 524 is connected to the fifth region. The fifth region is connected to the third region and also to the fourth region. The sixth region is connected to the third region and also to the fourth region.
[0217] For example, when the hot air delivered by the first air supply duct 521 enters the second air supply duct 522, due to the separation effect of the first separator 541, the hot air A is divided into two parts. 1 / 2 of the hot air enters the first area, and part of the hot air is discharged through the vent 510 connected to the first area, acting on the dishwasher structure and cabinet on one side of the inner liner 200 along the width direction. The remaining air volume B in the first area enters the third air supply duct 523.
[0218] The remaining 1 / 2A of hot air enters the third air supply duct 523 through the second zone, for a total of B+1 / 2A of hot air entering the third air supply duct 523. The third air supply duct 523 is equipped with a second separator 542. By designing the position and number of separators, the hot air in the air supply duct 520 can be separated and combined to ensure the amount of hot air delivered to each location in the air supply duct 520.
[0219] It should be noted that the dividers can be designed as multiple strips according to the actual situation, and the vent 510 position can be designed to be either merged or not, in order to ensure the uniformity of air supply.
