Description

Technical Field

[0001] The invention relates to a cleaning machine and a cleaning method thereof. Background Art

[0002] As people's living standards continue to improve, dishwashers, as a kitchen appliance, are increasingly entering households. Currently, dishwashers on the market are generally divided into three types: desktop, cabinet, and tank. Among them, desktop dishwashers are integrated independent structures and are generally placed on the table for use; cabinet dishwashers are also independent structures, but need to be embedded in kitchen cabinets for use; tank dishwashers are combined with sinks and are generally installed in kitchen cabinets for use.

[0003] For example, the Chinese patent "Sink Type Cleaning Machine" (application number: CN201310749864.9) with authorization announcement number CN103735237B of the applicant discloses a structure, which includes a box body forming a washing space, the box body includes a sink body, the sink body is concave at least in the central part, the concave part is covered with a drain plate of the same shape as the concave part, a plurality of drain holes for draining water are provided on the drain plate, the space between the concave part and the drain plate forms a drain area, the drain plate is flush with other parts of the bottom of the sink body, and a water pump is provided in the drain area to pump water out of the drain area to above the drain plate. When the above-mentioned washing machine is used for washing, generally in order to improve the cleanliness, at least one water layer in the cleaning process will be hot water, so that after washing, the residual heat of this part of hot water can also play a role in drying the dishes. However, since a large amount of water vapor is generated during the drying process of the dishes, and this part of the water vapor cannot be discharged in time, it will condense and adhere to the dishes and the inner wall surface of the washing machine as the temperature drops, which is easy to breed bacteria; and if an exhaust structure is set to quickly discharge the water vapor, it is easy to burn the user due to the hot steam, affecting the user experience. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a cleaning machine that can timely discharge water vapor and reduce the steam discharge temperature by enhancing the convection of cold and hot gases, thereby avoiding the breeding of bacteria and improving user experience in response to the current status of the prior art.

[0005] Another technical problem to be solved by the present invention is to provide a cleaning method for the above-mentioned cleaning machine in response to the current status of the prior art. The method simultaneously introduces cold air into the cleaning machine and exhausts the steam, thereby enhancing the convection of cold and hot gases inside and outside the cleaning machine, discharging the water vapor in the cleaning machine in time and avoiding the exhaust steam temperature being too high to burn the user, avoiding the breeding of bacteria and improving the user experience.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a cleaning machine, including a box body with a washing chamber, characterized in that: it also includes

[0011] The valve plate has a first end that is rotatably disposed on the inner wall of the air intake structure, and a second end that is a rotating free end that can block or connect the channel of the air intake body. When the valve plate blocks the channel of the air intake body, the first end of the first air duct remains connected to the first opening.

[0012] Preferably, the air intake body is formed into an inverted U-shaped structure, and the second end of the air intake body is arranged lower than the first end, and the top of the air intake body is arranged higher than the second opening. Such a structure is adopted to prevent water in the box from flowing back into the air intake body.

[0013] Preferably, the valve plate is arranged at the top of the air intake body, and the first end of the valve plate is arranged close to the top surface of the inner wall of the air intake body, and the second end of the valve plate can abut against the bottom surface of the inner wall of the air intake body to block the passage of the air intake body. The valve is arranged here, on the one hand, to prevent the backflow of water in the box from affecting the air intake mechanism, and on the other hand, to facilitate the diversion of the external cold air introduced into the air intake body.

The lower wall surface of the top of the air intake body is formed into an inverted V-shaped structure arranged in the middle of the corresponding flat plate, and the valve plate can cooperate with the inclined surface of the V-shaped structure near the first air guide pipe in the rotating state. The above structure is conducive to the assembly and opening and closing of the valve plate.

[0022] (3) The valve plate is opened to keep the channel of the air intake body unobstructed, and the air suction mechanism introduces external cold air into the air intake body. A part of the cold air in the air intake body enters the washing chamber from the first opening, thereby strengthening the gas convection in the box and allowing water vapor to be output from the second opening through the second air duct. At the same time, another part of the cold air in the air intake body does not enter the box through the first opening but directly enters the first air duct and mixes with the water vapor at the output end of the second air duct, and is further discharged at a lower temperature through the outlet end of the exhaust structure.

[0023] Compared with the prior art, the advantages of the present invention are: the air intake structure of the present invention can simultaneously introduce the inhaled external cold air into the washing chamber and the first air duct. The cold air introduced into the washing chamber can generate convection with the hot air in the box, so that water vapor is discharged into the second air duct from the second opening, and the cold air entering the first air duct is first mixed with the water vapor in the second air duct to reduce the steam temperature, and then discharged through the exhaust structure. Not only can the water vapor in the box be discharged to avoid condensation of water vapor and breeding of bacteria, but also the hot air can be prevented from burning the user, thereby improving the user experience.

A water tank 7 is arranged on one side of the housing 1. The exhaust structure 3 is installed on the outer wall of the water tank 7. The exhaust structure 3 has an air intake end 31 and an air outlet end 32. The side wall of the water tank 7 is provided with a third opening 71 that connects the inner cavity of the water tank 7 with the air outlet end 32 of the exhaust structure 3. The lower end of the exhaust structure 3 has an outlet 33 for discharging condensed water. The first end of the first air duct 4 is connected to the middle of the air intake structure 1, and a second opening 14 is formed on the second outer wall of the box body 1.

The first end of the second air duct 5 is connected to the second opening 14, and the second end of the second air duct 5 is connected to the air intake end 31 of the exhaust structure 3 after converging with the second end of the first air duct 4. The first end of the valve plate 6 is rotatably disposed on the inner wall of the air intake structure 2, and the second end of the valve plate 6 is a free end for rotation. The valve plate 6 can be rotated to block or connect the passage of the air intake body 21, and when the valve plate 6 blocks the passage of the air intake body 21, the first end of the first air duct 4 remains connected to the first opening 13.

[0030] The air intake body 21 of this embodiment is formed as an inverted U-shaped structure, and the second end of the air intake body 21 is arranged lower than the first end, and the top of the air intake body 21 is arranged higher than the second opening 14. Such a structure is adopted to prevent water in the box body 1 from flowing into the air intake body 21 when it flows back.

[0031] The valve plate 6 is arranged at the top of the air intake body 21, and the first end of the valve plate 6 is arranged close to the top surface of the inner wall of the air intake body 21, and the second end of the valve plate 6 can abut against the bottom surface of the inner wall of the air intake body 21 to block the passage of the air intake body 21. The valve 6 is arranged here, on the one hand, to prevent the backflow of water in the box body 1 from affecting the air intake mechanism 22, and on the other hand, to facilitate the diversion of the external cold air introduced into the air intake body 21. A horizontally arranged flat plate 211 is formed on the top of the air intake body 21, and the two sides of the flat plate 211 are respectively connected to inclined plates 212 that are gradually inclined outward from top to bottom, and the first end of the first air guide pipe 4 is connected to the inclined plate 212 close to the second end of the valve plate 6. The lower wall surface of the top of the air intake body 21 is formed into an inverted V-shaped structure 213 arranged in the middle of the flat plate 211. The valve plate 6 can cooperate with the inclined surface 2131 of the V-shaped structure 213 close to the first air duct 4 in the rotating state, thereby blocking the channel of the air intake body 21. A limiting column 214 is arranged on the inner wall of the air intake body 21 to limit the position of the valve plate 6 in the open state.

A part of the cold air in the air intake body 21 enters the washing chamber 10 from the first opening 13, thereby strengthening the gas convection in the box body 1, so that the water vapor is output from the second opening 14 through the second air duct 5; at the same time, another part of the cold air in the air intake body 21 does not enter the box body 1 through the first opening 13 but directly enters the first air duct 4 and mixes with the water vapor at the output end of the second air duct 5, and is further discharged at a lower temperature through the outlet end of the exhaust structure 4.

[0036] The air intake structure 1 of this embodiment can simultaneously introduce the inhaled external cold air into the washing chamber 10 and the first air duct 4. The cold air introduced into the washing chamber 10 can generate convection with the hot air in the box body 1, so that the water vapor is discharged into the second air duct 5 from the second opening 14. The cold air entering the first air duct 4 is first mixed with the water vapor in the second air duct 5 to reduce the steam temperature, and then discharged through the exhaust structure 3. Not only can the water vapor in the box body 1 be discharged to prevent the condensation of water vapor and the breeding of bacteria, but also the hot air can be prevented from burning the user, thereby improving the user experience.
