Description

Technical Field

[0001] The utility model relates to the technical field of kitchen equipment, in particular to a cleaning machine. Background Art

[0002] As people's living standards continue to improve, dishwashers, as a kitchen appliance, are increasingly entering households. Dishwashers generally include a cabinet, a dish rack for placing tableware, and a spray device disposed in the cabinet, which is used to draw water from the bottom of the cabinet into a water spray component and spray it onto the dish rack to rinse the tableware.

[0003] At present, household dishwashers on the market are generally equipped with an openable door in front of the dishwasher, which can be flattened after opening to allow the bowl basket to slide out. For the opening and closing operation of the door, in addition to daily opening and closing to facilitate the placement of tableware, it can also be controlled accordingly in conjunction with the washing function of the dishwasher. For example, the Chinese patent application number 202110759151.5, "A dishwasher and its automatic door opening mechanism", is an automatic door opening mechanism used to automatically open the dishwasher door to exhaust steam when the dishwasher is in the drying stage.

[0004] However, for built-in dishwashers, after the door is opened, the heat will spread around the cabinet, and the heat condenses into water droplets, causing the surface of the cabinet to become moist. Over time, the cabinet will become moldy and deteriorate, causing a bad experience for users. Utility Model Content

[0007] A box body having a cleaning chamber inside and an opening at the front side; and

[0008] The door body is hinged at the bottom edge of the bottom front side of the box body and is used to open and close the opening of the front side of the box body;

[0009] The feature is that: the box body is provided with an air curtain assembly, which includes

[0010] The air duct comprises a first pipe part and a second pipe part, wherein the first pipe part is arranged around the outer side of the edge of the front side of the box body except the bottom, an air outlet is opened on the front side surface of the first pipe part along its extension direction, an inlet end of the second pipe part is connected to the outside atmosphere, and an outlet end of the second pipe part is connected to the first pipe part; and

[0011] The first fan is arranged at the inlet of the second pipe part and can transport the airflow from the inlet to the outlet of the second pipe part.

[0012] In order to expand the coverage of the air curtain as much as possible, the first pipe portion is U-shaped.

[0013] In order to facilitate the installation of the second pipe part, the second pipe part is installed on the top side of the box body, and the outlet end of the second pipe part is connected to the upper part of the first pipe part.

[0014] In order to ensure that the outside atmosphere is transported to various positions of the first pipe part in time through the second pipe part, the second pipe part includes a main pipe and two branch pipes branching from the outlet end of the main pipe, the inlet end of the main pipe forms the inlet end of the second pipe part, and the outlet end of the branch pipe forms the outlet end of the second pipe part.

[0015] In order to achieve better ventilation and drying effects, an air inlet assembly for conveying external air to the cleaning chamber is provided outside the box.

[0016] In order to transport the outside air to the cleaning chamber, the air inlet assembly includes

[0017] An air hood, wherein an air duct is formed inside, the inlet of the air duct is connected to the outside atmosphere, and the outlet of the air duct is connected to the cleaning chamber; and

[0018] The second fan is arranged at the inlet of the air duct and can transport the air flow from the inlet to the outlet of the air duct.

[0019] In order to ensure that the outside atmosphere is evenly diffused throughout the cleaning chamber, the air duct includes a first air duct and a second air duct, the outlet of the first air duct is connected to the upper part of the cleaning chamber, and the outlet of the second air duct is connected to the lower part of the cleaning chamber.

[0020] In order to facilitate the installation of the second fan, the first air duct and the second air duct share an air inlet section, and the second fan is arranged at the entrance of the air inlet section.

[0021] In order to realize automatic door opening, a door opening device for pushing the door body open is provided on the top of the box body.

[0022] In order to ensure aesthetics, when the door body is closed, the front surface of the door body is flush with the front end surface of the cabinet.

[0023] Compared with the prior art, the utility model has the advantages that an air curtain assembly is arranged outside the box to form an air curtain wall on the front side of the box, thereby isolating hot air from the cabinet, thereby preventing the outflowing hot air from wetting the cabinet and causing it to mold.

[0040] The door opening device 5 is installed on the top of the box body 1, and is used to push open the above-mentioned door body 2. The specific structure of the door opening device 5 can refer to the background patents and other solutions, and will not be repeated here.

[0041] The above-mentioned cleaning machine has at least three states:

[0042] In the first state, the door body 2 is in a closed state, and the air curtain assembly 3 and the air inlet assembly 4 are both closed;

[0043] In the second state, the door body 2 is in an open state, and the air curtain assembly 3 and the air inlet assembly 4 are both started;

[0044] In the third state, the door body 2 is in an open state, the air curtain assembly 3 is closed, and the air inlet assembly 4 is started.

[0045] The working principle of this embodiment is as follows:

[0046] (1) Cleaning mode: the cleaning machine is switched to the first state, the door body 2 is in the closed state, the air curtain assembly 3 and the air inlet assembly 4 are both closed, and the spray device cleans the tableware on the dish rack;

[0047] (2) Drying mode: The cleaning machine is switched to the second state, the door body 2 is in the open state, the air curtain assembly 3 and the air inlet assembly 4 are both started, at this time, the hot air in the cleaning chamber 11 is discharged through the gap between the door body 2 and the box body 1, the first fan 32 transports the outside air to the first pipe part 311 through the main pipe 3121 and the branch pipe 3122 in turn and discharges it through the air outlet 3111 to form a wind curtain wall, isolating the hot air from the cabinet 10 to prevent the outflowing hot air from wetting the cabinet 10, at the same time, the second fan 42 transports the outside air to the upper and lower parts of the cleaning chamber 11 through the first air duct 411 and the second air duct 412 respectively, so that the hot air in the cleaning chamber 11 is quickly condensed, and then flows from the inner wall of the chamber to the bottom of the cleaning machine for discharge, achieving better ventilation and drying effects;

[0048] (3) Deodorization mode: The cleaning machine is switched to the third state, with the door body 2 in the open state, the air curtain assembly 3 closed, and the air inlet assembly 4 started. At this time, the second fan 42 transports the outside air to the upper and lower parts of the cleaning chamber 11 through the first air duct 411 and the second air duct 412, respectively, to achieve ventilation of the cleaning chamber 11, ensuring that there is no odor every time the user opens the door to use the cleaning machine.
