[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 water tanks and are generally installed in kitchen cabinets for use.

[0003] The various forms of dishwashers mentioned above generally use a water pump to lift water and spray it onto the dishes in the cleaning space to achieve the cleaning effect. For details, please refer to the Chinese patent application number 201721042136.4 previously applied by the applicant, "A spray arm and a cleaning machine using the spray arm".

[0004] However, in the above scheme, the spray arm cannot spray the entire cleaning chamber when it is working. When there are few dishes to be cleaned or individual dishes need to be cleaned intensively, precise spraying cannot be performed, the cleaning effect is poor, and the amount of cleaning water will be wasted. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a cleaning machine capable of improving the cleaning effect and saving the amount of cleaning water in view of the current status of the prior art.

[0006] The utility model solves the above technical problems by adopting the following technical solution: a cleaning machine, comprising a box body with a cleaning chamber and a spraying device for spraying cleaning water into the cleaning chamber, characterized in that: the spraying device comprises

[0007] A water inlet arm, having a first flow channel inside, a first end rotatably connected to the box body and having a first water inlet, and a second end being a free end and having a water outlet;

[0008] A plurality of spray arms are radially arranged on the periphery of the rotation area of ​​the water inlet arm, each spray arm has a second flow channel inside, an inward end of the spray arm has a second water inlet, and a side portion of the spray arm has a plurality of spray holes arranged at intervals along its extension direction; and

[0009] The first driving member is used to drive the water inlet arm to rotate around its first end so that the water outlet is connected to the second water inlet of any spray arm.

[0010] In order to realize automatic delivery of water flow, a water pumping mechanism is also included for pumping clean water to the first water inlet.

[0011] In order to facilitate the supply of clean water, a clean water tank for storing clean water is also included, and the first water inlet is connected to the inner cavity of the clean water tank.

[0012] In order to facilitate the cleaning water to cover the entire cleaning cavity in the height direction after flowing out from the spray hole, the spray hole is located on the bottom wall of the spray arm.

[0013] In order to facilitate the installation of the spray device, the top of the box body is provided with a mounting cover, and an mounting cavity is formed between the mounting cover and the top wall of the box body. The spray device is arranged in the mounting cavity, and the bottom wall of the spray arm and the bottom wall of the mounting cavity share the same wall surface.

[0014] In order to simplify the processing of the spray arm, the top wall of the spray arm and the top wall of the installation cavity share the same wall surface.

[0015] To facilitate the installation of the clean water tank, the clean water tank is installed on the top of the mounting cover, and the first end of the water inlet arm is rotatably connected to the top wall of the mounting cover via a rotating shaft.

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0027] like Figures 1 to 3 FIG. 1 is a preferred embodiment of the cleaning machine of the present invention. The cleaning machine comprises a housing 1 , a spray device 2 , a clean water tank 3 and a water pump mechanism 4 .

[0028] The box body 1 has a cleaning chamber 11 inside, and a mounting cover 12 is provided on the top of the box body 1 . A mounting chamber 121 is formed between the mounting cover 12 and the top wall of the box body 1 .

[0029] The spray device 2 is disposed in the installation cavity 121 and is used for spraying cleaning water into the cleaning cavity 11 .

[0030] In this embodiment, the spray device 2 includes a water inlet arm 21 , a spray arm 22 , a first driving member 23 and a valve assembly 24 .

[0031] Specifically, the water inlet arm 21 is arranged in the middle of the installation cavity 121 along the horizontal direction. The water inlet arm 21 has a first flow channel 211 inside; the first end of the water inlet arm 21 is rotatably connected to the top wall of the installation cover 12 through a rotating shaft 212, and the interior of the rotating shaft 212 is provided with a first water inlet 2121 that is axially connected to the first flow channel 211; the second end of the water inlet arm 21 is a free end, and the port of the free end is recorded as a water outlet 213.

[0032] There are multiple spray arms 22, which are radially arranged on the periphery of the rotation area of ​​the water inlet arm 21, and the bottom wall of the spray arm 22 shares the same wall surface with the bottom wall of the installation cavity 121, and the top wall of the spray arm 22 shares the same wall surface with the top wall of the installation cavity 121. Each spray arm 22 has a second flow channel 221 inside, and the second flow channel 221 includes a plurality of flow channel units 2211 arranged in sequence along its extension direction; the port at the inward end of the spray arm 22, i.e., the front end of the frontmost flow channel unit 2211, is recorded as the second water inlet 222; the bottom side of the front end of each flow channel unit 2211 has a spray hole 223; and the side wall of each flow channel unit 2211 has a mounting groove 224 at the position corresponding to the spray hole 223.

[0033] The first driving member 23 is a motor installed on the bottom wall of the installation cavity 121 , and its power output end is connected to the rotating shaft 212 , and is used to drive the water inlet arm 21 to rotate around the axis of the rotating shaft 212 so that the water outlet 213 is connected to the second water inlet 222 of any spray arm 22 .

[0034] There are multiple valve assemblies 24 corresponding one to one with the above-mentioned flow channel units 2211. Each valve assembly 24 is installed at the corresponding flow channel unit 2211, and can open the corresponding flow channel unit 2211 and close the corresponding spray hole 223 under the action of water flow.

[0035] In this embodiment, the valve assembly 24 includes a valve block 241, a valve plate 242 and an elastic member 243. The valve block 241 is rotatably mounted in the corresponding mounting groove 224, and a flow hole 2411 is provided on the valve block 241; the valve plate 242 is connected to the top of the valve block 241 and is blocked in the corresponding flow channel unit 2211; the elastic member 243 is a torsion spring, which is sleeved on the outer periphery of the valve block 241, and the two ends of the torsion spring are respectively abutted against the outer peripheral wall of the valve block 241 and the inner peripheral wall of the mounting groove 224, so that the valve plate 242 always has a tendency to block the corresponding flow channel unit 2211, and at the same time, the communication hole 2411 of the valve block 241 always has a tendency to be connected with the corresponding spray hole 223. Therefore, when no external force acts on the valve plate 242, the corresponding flow channel unit 2211 is in a closed state, and the corresponding spray hole 223 is in an open state; when water flows on the valve plate 242 and the force is large enough, the valve plate 242 will overcome the elastic force of the elastic member 243 under the action of the water flow and flip over, on the one hand, removing the obstruction to the corresponding flow channel unit 2211 and opening the flow channel unit 2211, and on the other hand, driving the valve block 241 to rotate and cover the corresponding spray hole 223 and close the spray hole 223.

[0036] In addition, the torsion spring rotational force of the rear valve assembly 24 is greater than the torsion spring rotational force of the front valve assembly 24. Therefore, the water flow pressure required for the rear valve assembly 24 to open the corresponding flow channel unit 2211 is greater than the water flow pressure required for the front valve assembly 24 to open the corresponding flow channel unit 2211, thereby ensuring that the water flow can flow out from each spray hole 223.

[0037] The clean water tank 3 is used to store electrolyzed water as clean water, and the clean water tank 3 is installed on the top of the installation cover 12, and the bottom wall of the clean water tank 3 shares the same wall surface with the top wall of the installation cover 12. The top end of the rotating shaft 212 passes through the bottom wall of the clean water tank 3 and extends into the clean water tank 3, so that the first water inlet 2121 is connected to the inner cavity of the clean water tank 3.

[0038] The pumping mechanism 4 is used to pump the clean water in the clean water tank 3 to the first water inlet 2121, and includes an impeller 41 and a second driving member 42. Specifically, the impeller 41 is accommodated in the clean water tank 3; the second driving member 42 is a motor installed on the bottom wall of the installation cavity 121, and its power output end passes through the first water inlet 2121 and is connected to the impeller 41, so as to drive the impeller 41 to rotate.

[0039] The working principle of this embodiment is as follows: when a certain area of ​​the cleaning chamber 11 needs to be cleaned, the first driving member 23 is first started to drive the water inlet arm 21 to rotate to a corresponding angle to communicate with the second water inlet 222 of the corresponding spray arm 22, and then the water pump mechanism 4 is started to pump the cleaning water into the water inlet arm 21 and transport it to the corresponding spray arm 22, and the water pressure of the cleaning water is controlled so that the cleaning water flows out from the corresponding spray hole 223;

[0040] For example, if the first spray hole 223 in the second flow channel 221 needs to be opened, the water pressure needs to be controlled to be smaller than the torsion spring rotation force of the first valve assembly 24, and the water flows out from the first spray hole 223;

[0041] If it is necessary to open the second spray hole 223 in the second flow channel 221, it is necessary to control the water pressure to be greater than the torsion spring rotation force of the first valve assembly 24 and less than the torsion spring rotation force of the second valve assembly 24. In this way, the valve plate 242 of the first valve assembly 24 turns over, opens the first flow channel unit 2211 and closes the first spray hole 223. When the water reaches the second valve assembly 24, the water pressure is less than the torsion spring rotation force of the valve assembly 24. Therefore, the valve plate 242 of the second valve assembly 24 does not turn over, and the water flows out from the second spray hole 223.

[0042] If the third spray hole 223 in the second flow channel 221 needs to be opened, the water pressure needs to be controlled to be greater than the torsion spring rotation force of the second valve assembly 24 and less than the torsion spring rotation force of the third valve assembly 24, and so on.
