Description

Technical Field

[0001] The present application relates to the field of kitchen and bathroom machinery, and in particular to a dishwasher. Background Art

[0002] Washing dishes is an essential part of daily life. The oil stains on the dishes can easily lead to greasy hands. At the same time, people's pace of life is getting faster and faster, and the cleaning efficiency is low and the time is long during the daily dishwashing process. Therefore, dishwashers are increasingly widely used in people's daily lives.

[0003] In the related art, the working process of a dishwasher is divided into a washing stage and a drying stage. In the washing stage, the dishwasher is a device that can spray hot water or cold water onto dishes to remove dirt adhering to the dishes and clean the dishes; in the drying stage, the hot and humid air in the inner cavity of the dishwasher is discharged to the outside of the dishwasher, and the dry air outside the dishwasher enters the inner cavity of the dishwasher, thereby drying the tableware in the inner cavity of the dishwasher.

[0004] However, in the process of the hot and humid air in the above-mentioned drying stage being discharged to the outside of the dishwasher, the condensation efficiency of the hot and humid air is poor, which affects the drying performance of the dishwasher. At the same time, the uncondensed hot and humid air will condense on the kitchen wall or chopping board after being discharged, thereby aggravating the user's cleaning work. Utility Model Content

[0051] Washing dishes is an essential part of daily life. The oil stains on the dishes can easily lead to greasy hands. At the same time, people's pace of life is getting faster and faster, and the cleaning efficiency is low and the time is long during the daily dishwashing process. Therefore, dishwashers are increasingly widely used in people's daily lives.

[0052] In the related art, the working process of a dishwasher is divided into a washing stage and a drying stage. In the washing stage, the dishwasher is a device that can spray hot water or cold water onto dishes to remove dirt adhering to the dishes and clean the dishes; in the drying stage, the hot and humid air in the inner cavity of the dishwasher is discharged to the outside of the dishwasher, and the dry air outside the dishwasher enters the inner cavity of the dishwasher, thereby drying the tableware in the inner cavity of the dishwasher.

[0053] However, in the process of the hot and humid air in the above-mentioned drying stage being discharged to the outside of the dishwasher, the condensation efficiency of the hot and humid air is poor, which affects the drying performance of the dishwasher. At the same time, the uncondensed hot and humid air will condense on the kitchen wall or chopping board after being discharged, thereby aggravating the user's cleaning work.

[0054] Based on this, the present application provides a dishwasher that can quickly condense the hot and humid air discharged from the inner cavity of the dishwasher, thereby improving the drying performance of the dishwasher and reducing the cleaning work of the user. The specific structure and corresponding functions of the dishwasher in the present application will be described in detail below in conjunction with the drawings of the specification.

[0055] Figure 1 FIG. 1 shows one of the overall structural diagrams of the dishwasher provided in the embodiment of the present application, referring to FIG. Figure 1 In some embodiments of the present application, the dishwasher 1 may include a dishwasher body 10, and the dishwasher body 10 has a dishwasher cavity 11. In this way, the user can place items to be washed, such as bowls, plates, chopsticks or spoons, in the dishwasher cavity 11.

[0056] It should be noted that the inner cavity 11 of the dishwasher can also be provided with multiple bowl baskets, such as a first bowl basket 12 and a second bowl basket 13 arranged up and down. At this time, bowls, plates or tea cups can be placed in the upper first bowl basket 12, and chopsticks, spoons or knives and forks can be placed in the lower second bowl basket 13, so as to facilitate users to store and organize after washing.

[0057] Figure 2The second schematic diagram of the overall structure of the dishwasher provided in the embodiment of the present application is shown. Figure 2 In some embodiments of the present application, the dishwasher 1 may further include an exhaust assembly 20 and an air intake assembly 30 , and both the exhaust assembly 20 and the air intake assembly 30 are connected to the dishwasher body 10 .

[0058] During the drying stage of the dishwasher 1, the exhaust component 20 operates to exhaust the hot and humid air in the inner cavity 11 of the dishwasher, so that the air pressure in the inner cavity 11 of the dishwasher is lower than the air pressure in the external environment of the dishwasher 1. The dry and low-temperature air in the external environment flows into the inner cavity 11 of the dishwasher through the air intake component 30 under the action of atmospheric pressure, and dries the tableware in the inner cavity 11 of the dishwasher.

[0059] Figure 3 The exploded structure diagram of the exhaust assembly provided in the embodiment of the present application is shown. Figure 4 One of the structural schematic diagrams of the exhaust assembly provided in the embodiment of the present application is shown, Figure 5 The second structural diagram of the exhaust assembly provided in the embodiment of the present application is shown in conjunction with Figure 3 , Figure 4 and Figure 5 In some embodiments of the present application, the exhaust assembly 20 may include a shell 21, in which a first cavity 211 and a second cavity 212 are formed. The first cavity 211 is connected to the inner cavity 11 of the dishwasher through a first air inlet 24, and the second cavity 212 is connected to the external air through a second air inlet 27.

[0060] in, Figure 4 and Figure 5 The arrow lines marked in the figure indicate the flow direction of humid hot air and dry air. It can be seen that the humid hot air in the inner cavity 11 of the dishwasher can enter the first cavity 211 of the exhaust component 20 through the first air inlet 24, and the dry air outside the dishwasher 1 can enter the second cavity 212 of the exhaust component 20 through the second air inlet 27.

[0061] Figure 6 The third structural diagram of the exhaust assembly provided in the embodiment of the present application is shown. Figure 6 In some embodiments of the present application, the exhaust assembly 20 may further include a condensation channel 213, which is connected to both the first cavity 211 and the second cavity 212. In this way, the high-temperature humid hot air in the first cavity 211 and the low-temperature dry air in the second cavity 212 can flow into the condensation channel 213 and mix with each other, and the low-temperature air can cool the high-temperature air to promote the condensation of the humid hot air.

[0062] Continue reading Figure 4 and Figure 5 and Figure 6In some embodiments of the present application, the exhaust component 20 may further include an airflow driving component 22, which may include a first rotating member 221 and a second rotating member 222. The first rotating member 221 is arranged in the first cavity 211, and is used to send the air in the dishwasher cavity 11 into the condensation channel 213 through the first cavity 211. The second rotating member 222 is arranged in the second cavity 212, and is used to send external air into the condensation channel 213 through the second cavity 212.

[0063] In which, within a unit time, the air output of the first rotating member 221 is greater than the air output of the second rotating member 222 .

[0064] It should be noted that, in the related art, the hot and humid air in the inner cavity 11 of the dishwasher and the dry air outside the dishwasher 1 are usually mixed in equal proportions. After research, the inventor of the present application found that the above-mentioned structural design causes the hot and humid air to be excessively diluted by the dry air, which is not conducive to the condensation of the hot and humid air in the condensation channel 213, affecting the drying efficiency of the dishwasher 1. At the same time, when the hot and humid air that has not yet condensed is discharged into the kitchen, it will condense on the wall or chopping board of the kitchen, making the user's cleaning work more aggravated.

[0065] In the present application, the air output of the first rotating member 221 is set to be greater than the air output of the second rotating member 222 , so that the hot and humid air flowing into the condensation channel 213 is greater than the dry air flowing into the condensation channel 213 .

[0066] In this way, the humid hot air can be promoted to be condensed by the low-temperature dry air at a suitable density, thereby improving the condensation efficiency of the humid hot air and the drying performance of the dishwasher 1. At the same time, it also reduces the uncondensed humid hot air discharged into the kitchen, thereby reducing the user's cleaning work.

[0067] There may be multiple implementation forms for the specific implementation form of the air output of the first rotating member 221 being greater than the air output of the second rotating member 222 .

[0068] In one possible structural design, Figure 7 FIG. 4 shows a fourth structural diagram of an exhaust assembly provided in an embodiment of the present application, referring to FIG. Figure 7 The airflow driving assembly 22 may further include a rotating substrate 223 , which is disposed between the first cavity 211 and the second cavity 212 to separate the inner cavity of the shell 21 into the first cavity 211 and the second cavity 212 .

[0069] In some embodiments of the present application, the first rotating member 221 may include a plurality of first blades disposed in the first cavity 211, the plurality of first blades being connected to the rotating substrate 223 and being arranged at intervals in the circumferential direction around the rotation center axis of the rotating substrate 223. Similarly, the second rotating member 222 may include a plurality of second blades disposed in the second cavity 212, the plurality of second blades being disposed on a side of the rotating substrate 223 away from the first blades and being arranged at intervals in the circumferential direction around the rotation center axis of the rotating substrate 223.

[0070] In this way, when the rotating substrate 223 rotates around the rotation center axis of the rotating substrate 223, the multiple first blades and the multiple second blades installed on both sides of the rotating substrate 223 can simultaneously drive the hot and humid air inside the dishwasher to enter the condensation channel 213 through the first cavity 211, and the dry air outside the dishwasher 1 to enter the condensation channel 213 through the second cavity 212.

[0071] The plurality of first blades and the plurality of second blades are arranged in one-to-one correspondence, and the projection area of ​​the first blade on the reference plane is larger than the projection area of ​​the second blade arranged opposite to the first blade on the reference plane, and the reference plane is a plane perpendicular to the plane where the rotating substrate 223 is located. In other words, the surface area of ​​the first blade is larger than the surface area of ​​the second blade.

[0072] It can be understood that when the surface area of ​​the first blade is larger than the surface area of ​​the second blade, when a motor is used to drive the rotating substrate 223 to rotate, although the rotation speed of the rotating substrate 223 is constant, the air volume passing through the first cavity 211 and the second cavity 212 on both sides of the rotating substrate 223 per unit time is different. The surface area of ​​the first blade located in the first cavity 211 is larger and can drive more air flow. Therefore, the hot and humid air entering the condensation channel 213 from the inner cavity 11 of the dishwasher through the first cavity 211 is greater than the low-temperature dry air entering the condensation channel 213 from the external air through the second cavity 212.

[0073] It should be noted that, although most of the first cavity 211 and the second cavity 212 are separated by the rotating substrate 223, there is a gap between the outer ring of the rotating substrate 223 and the housing 21, and the first cavity 211 and the second cavity 212 can be connected through this gap. In this way, when the humid hot air enters the first cavity 211 and the dry air enters the second cavity 212, the humid hot air and the dry air are both transported to the gap part of the outer ring of the rotating substrate 223 under the action of centrifugal force, and the humid hot air and the dry air are fully mixed at the gap position, and then transported to the condensation channel 213, so as to promote the condensation efficiency of the humid hot air.

[0074] There may be many specific forms in which the surface area of ​​the first blade is greater than the surface area of ​​the second blade.

[0075] For example, Figure 8 FIG. 1 shows one of the structural schematic diagrams of the airflow drive assembly 22 provided in the embodiment of the present application, see FIG. Figure 8 The length of the first blade along the second direction is greater than the length of the second blade along the second direction, and the second direction is the arrangement direction of the first blade, the rotating substrate 223 and the second blade.

[0076] Exemplarily, the length of the first blade along the radial extension direction of the rotating substrate 223 may be greater than the length of the second blade along the radial extension direction of the rotating substrate 223 .

[0077] In another possible structural design, Fig. 9 FIG. 2 shows a second structural diagram of an airflow drive assembly provided in an embodiment of the present application. Fig. 9 In some embodiments of the present application, the airflow drive assembly 22 may also include a first drive motor 224 and a second drive motor 225, the first drive motor 224 is connected to the first rotating member 221, and the second drive motor 225 is connected to the second rotating member 222, wherein the rotation speed of the first drive motor 224 is greater than the rotation speed of the second drive motor 225.

[0078] That is to say, the present application may not improve the first rotating member 221 or the second rotating member 222, but may use two independent motors to drive the first rotating member 221 and the second rotating member 222 to perform differential rotation, thereby achieving different air output volumes.

[0079] Fig.10 The fifth structural diagram of the exhaust assembly provided in the embodiment of the present application is shown. Fig.11 The sixth structural diagram of the exhaust assembly provided in the embodiment of the present application is shown in conjunction with Figure 2 , Fig.10 and Fig.11 In some embodiments of the present application, the shell 21 is formed with an exhaust channel 214, one end of the exhaust channel 214 is connected to the inner cavity 11 of the dishwasher, and the other end of the exhaust channel 214 is connected to the condensation channel 213, the first cavity 211 and the second cavity 212 are both located in the exhaust channel 214, and the arrangement direction of the first cavity 211 and the second cavity 212 in the exhaust channel 214 is perpendicular to the wind direction in the exhaust channel 214.

[0080] In some embodiments of the present application, the exhaust assembly 20 may further include a spacer 23 , which abuts against the shell 21 , and is used to prevent the gas in the dishwasher cavity 11 from entering the second cavity 212 , so that the gas enters the first cavity 211 .

[0081] That is to say, since the spacer 23 divides a section of the exhaust channel into the first cavity 211 and the second cavity 212, the right side of the spacer 23 is the first cavity 211, the left side of the spacer 23 is the second cavity 212, and the top of the spacer 23 abuts against the left side of the shell 21. In this way, when the hot and humid air in the inner cavity 11 of the dishwasher flows from top to bottom along the exhaust channel and encounters the partition plate, all the hot and humid air will be guided to the first cavity 211 on the right, while the low-temperature dry air in the external environment is concentrated in the second cavity 212 on the left. The two enter the condensation channel 213 and mix under the action of the airflow driving component 22.

[0082] It can be understood that the spacer 23 in the present application combined with the rotating substrate 223 can enable the humid hot air and the dry air to pass through the exhaust channel 214 in an orderly manner, and enter the condensation channel 213 after being evenly mixed in the outer circle of the rotating substrate 233, thereby avoiding turbulence when the humid hot air and the dry air are mixed.

[0083] Fig.12 The structure diagram of the damper control assembly provided by the embodiment of the present application in the first position is shown. Fig.13 The structure diagram of the damper control assembly provided by the embodiment of the present application in the second position is shown in conjunction with Figure 2 , Fig.12 and Fig.13 In some embodiments of the present application, the housing 21 has a first air inlet 24 connected to the inner cavity 11 of the dishwasher, and the hot and humid air in the inner cavity 11 of the dishwasher can enter the exhaust assembly 20 through the first air inlet 24 .

[0084] In some embodiments of the present application, the exhaust assembly 20 may further include a damper control assembly 25, which is used to control the opening and closing state of the first air inlet 24, and may include a driving member 251 and a valve body 252. The driving member 251 may include a driving shaft, which can move toward the first air inlet 24. The valve body 252 is connected to the driving shaft and has a first position and a second position.

[0085] When the valve body 252 is located at the first position, the valve body 252 is spaced apart from the first air inlet 24 , thereby opening the first air inlet 24 ; when the valve body 252 is located at the second position, the valve body 252 abuts against the first air inlet 24 , thereby closing the first air inlet 24 .

[0086] It is understandable that when the dishwasher 1 is in the washing stage, the first air inlet 24 can be closed by the damper control assembly 25, so that the inner cavity 11 of the dishwasher is in a sealed state, thereby preventing the heat loss of the inner cavity 11 of the dishwasher, ensuring the cleaning effect of the dishwasher 1, and at the same time, preventing water from entering the exhaust assembly 20. When the dishwasher 1 is in the drying stage, the first air inlet 24 can be opened by the damper control assembly 25, so that the hot and humid air in the inner cavity 11 of the dishwasher is quickly discharged under the action of the exhaust assembly 20, thereby ensuring the drying effect of the dishwasher 1.

[0087] Fig.14 The figure shows a schematic diagram of the assembly structure of the air intake plate and the dishwasher body provided in the embodiment of the present application.

In this way, the hot and humid air in the inner cavity 11 of the dishwasher can pass through the gap to the first air inlet of the exhaust assembly 20.

[0088] Fig.16 FIG7 shows a seventh structural diagram of an exhaust assembly provided in an embodiment of the present application. Fig.17 The structure diagram of the air intake disk provided in the embodiment of the present application is shown in conjunction with Fig.15 , Fig.16 and Fig.17 In some embodiments of the present application, the air inlet plate 26 may include a first wall surface 261, and the first wall surface 261 may be flush with the wall surface of the dishwasher body 10 on the side away from the exhaust assembly 20. In this way, the first wall surface 261 can not only block the washing water from entering the exhaust channel during the washing stage, but also does not occupy the space inside the dishwasher 1.

[0089] In some embodiments of the present application, the air inlet disk 26 may further include a second wall surface 262 , one side of the second wall surface 262 is connected to the shell 21 , and the other side of the second wall surface 262 is spaced apart from the first wall surface 261 .

[0090] In some embodiments of the present application, the air inlet disc 26 may further include a plurality of connectors 263, which are arranged at intervals in the circumferential direction around the axis of the air inlet disc 26, and the opposite ends of each connector 263 are respectively connected to the first wall surface 261 and the second wall surface 262, and a plurality of air inlet cavities 264 are enclosed with the dishwasher body 10, and the air inlet cavities 264 can be communicated with the first air inlet 24. In this way, the hot and humid gas in the inner cavity 11 of the dishwasher can flow toward the first air inlet 24 from all directions of the air inlet disc 26 through the plurality of air inlet cavities 264.

[0091] Fig.18 FIG. 8 shows a schematic diagram of the structure of the exhaust assembly provided in the embodiment of the present application. Fig.18 In some embodiments of the present application, a second air inlet 27 connected to the second cavity 212 is also formed on the shell 21, so that external low-temperature dry air can enter the second cavity 212 through the second air inlet 27.

[0092] Fig.19 A schematic diagram of the structure of the condensation channel and the air outlet channel provided in an embodiment of the present application is shown. In some embodiments of the present application, the condensation channel 213 may include a bent channel 2131, so that the hot and humid air in the dishwasher cavity 11 and the external low-temperature dry air can be condensed and deposited at the bent channel 2131.

[0093] In some embodiments of the present application, the condensation channel 213 may further include a reflux channel 2132, one end of the reflux channel 2132 is connected to the bending channel 2131, and the other end of the reflux channel 2132 is connected to the dishwasher cavity 11. In this way, the condensed water deposited in the bending channel 2131 can be introduced into the bottom of the dishwasher cavity 11.

[0094] Continue reading Fig.19 In some embodiments of the present application, the housing 21 may further include an air outlet channel 28, which is connected to the bending channel 2131. In this way, the condensed gas is discharged from the air outlet channel 28 to the outside of the dishwasher 1, preventing the gas from condensing into water droplets in the kitchen.

[0095] In summary, the dishwasher 1 provided in this application mainly has the following advantages:

[0096] (1) The air volume of the first rotating member 221 of the present application is greater than the air volume of the second rotating member 222, so that the humid hot air flowing into the condensation channel 213 is greater than the dry air flowing into the condensation channel 213, which promotes the condensation of the humid hot air by the low-temperature dry air at a suitable density, thereby improving the condensation efficiency of the humid hot air and the drying performance of the dishwasher 1. At the same time, it also reduces the humid hot air that has not yet condensed and is discharged into the kitchen, thereby reducing the cleaning work of the user;

[0097] (2) The multiple first blades and multiple second blades installed on both sides of the rotating base plate 223 of the present application can simultaneously drive the hot and humid air inside the dishwasher 1 to enter the condensation channel 213 through the first cavity 211, and the external dry air to enter the condensation channel 213 through the second cavity 212, and can control the ratio of the hot and humid air to the low-temperature dry air in the condensation channel 213 by controlling the size of the first blades and the second blades, and the structure is simple;

[0098] (3) The present application can control the opening and closing of the first air inlet 24 through the damper control component 25. When the dishwasher 1 is in the washing stage, the first air inlet 24 is controlled to be closed, so that the inner cavity 11 of the dishwasher is in a sealed state, thereby preventing the heat loss of the inner cavity 11 of the dishwasher, ensuring the cleaning effect of the dishwasher 1, and at the same time, preventing water from entering the exhaust component 20. When the dishwasher 1 is in the drying stage, the first air inlet 24 is controlled to be open, so that the hot and humid air in the inner cavity 11 of the dishwasher is quickly discharged under the action of the exhaust component 20, thereby ensuring the drying effect of the dishwasher 1.
