[0001] This utility model relates to the field of kitchen equipment technology, specifically to a top spray arm mounting structure for a cleaning machine and the cleaning machine itself. Background Technology

[0002] For the installation structure of the top spray arm of the dishwasher, the existing solutions mostly connect the top spray arm to the water outlet of the inner water pipe through a connecting pipe, and fix the inner water pipe to the top wall of the inner tank through a fixing bracket, thereby realizing the connection between the top spray arm and the inner tank. For details, please refer to the Chinese patent "Fixing Structure of Inner Water Pipe of Dishwasher" with patent application number CN201720946570.9.

[0003] However, in the above solution, the connection between the top spray arm and the connecting pipe is far from the connection between the fixed bracket and the inner liner, that is, the installation dimension chain of the top spray arm is long, which leads to a large positional error and a large amount of shaking of the top spray arm during installation. Utility Model Content

[0004] The first technical problem to be solved by this utility model is to provide a top spray arm mounting structure for a cleaning machine that provides a precise installation position and minimal sway of the top spray arm, in light of the current state of the technology.

[0005] The second technical problem to be solved by this utility model is to provide a cleaning machine that uses the above-mentioned top spray arm mounting structure.

[0006] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a top spray arm mounting structure for a cleaning machine, including an inner tank, an inner water pipe, a top spray arm, and a connecting pipe for connecting the inner water pipe and the top spray arm, characterized in that: the connecting pipe is connected to the top wall of the inner tank.

[0007] In order to connect the connecting pipe to the inner liner, a clearance hole is provided on the top wall of the inner liner, and a mounting bracket is provided on the outer side of the inner liner at the position of the clearance hole. A mounting post is protruding on the side wall of the top side of the connecting pipe, and the mounting post passes upward through the clearance hole and is connected to the mounting bracket.

[0008] To conceal the mounting post and improve aesthetics, the mounting bracket has an outwardly protruding bulge at the position opposite the clearance hole, which surrounds the outer periphery of the top of the mounting post.

[0009] To achieve the connection between the mounting column and the mounting bracket, the mounting column is provided with an axially extending blind mounting hole, and the top wall of the bulge is provided with a mounting hole corresponding to the blind mounting hole. The connecting pipe and the inner liner are connected to each other through the blind mounting hole of the mounting column and the mounting hole of the mounting bracket and fixed by fasteners.

[0010] Preferably, the fastener is a screw.

[0011] To prevent water leakage during cleaning, the mounting post is sealed to the top wall of the inner liner.

[0012] In order to achieve a sealed fit between the mounting post and the top wall of the inner liner, the outer peripheral wall of the mounting post is provided with a boss that extends outward and then upward. The boss and the outer peripheral wall of the mounting post surround and form an annular groove with the opening facing upward. A sealing ring is embedded in the annular groove and abuts against the top wall of the inner liner located on the outer periphery of the relief hole.

[0013] To achieve the connection between the inner water pipe and the top spray arm, the connecting pipe includes a horizontal section extending from back to front and a vertical section extending downward from the front end of the horizontal section. The rear end of the horizontal section is connected to the water outlet end of the inner water pipe, and the water inlet end on the top side of the top spray arm is rotatably connected to the bottom end of the vertical section.

[0014] To minimize the installation dimension chain of the top spray arm, the mounting column is arranged coaxially with the vertical section.

[0015] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a cleaning machine, characterized in that: it applies the above-mentioned top spray arm mounting structure.

[0016] Compared with the prior art, the advantages of this utility model are: this solution expands the function of the connecting pipe, allowing it to connect the inner water pipe, the top spray arm and the inner tank at the same time, reducing the installation dimension chain of the top spray arm, improving the accuracy of its installation position, and making it more conducive to its stable movement and reducing shaking.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0021] like Figures 1 to 2 The image shows a preferred embodiment of the cleaning machine with a top spray arm mounting structure according to this utility model. The top spray arm mounting structure includes an inner tank 1, an inner water pipe 2, a top spray arm 3, and a connecting pipe 4 disposed within the inner tank 1.

[0022] Specifically, a clearance hole 11 is provided on the top wall of the inner liner 1, and a mounting bracket 12 is provided on the outer side of the inner liner 1 at a position on the outer periphery of the clearance hole 11. Specifically, the mounting bracket 12 has an outwardly protruding bulge 121 at a position directly opposite the clearance hole 11, and a mounting hole 1211 is provided on the top wall of the bulge 121.

[0023] The inner water pipe 2 is installed on the rear side wall inside the inner tank 2, and its bottom water inlet is used to connect to the water pump of the cleaning machine.

[0024] The top spray arm 3 is located at the top of the inner cavity of the inner liner 2 and is used to spray the upper space of the inner cavity of the inner liner 2.

[0025] The connecting pipe 4 is used to connect the inner water pipe 2 and the top spray arm 3. Specifically, the connecting pipe 4 includes a horizontal section 401 extending from back to front and a vertical section 402 extending downward from the front end of the horizontal section 401. The rear end of the horizontal section 401 is connected to the water outlet at the top of the inner water pipe 2, and the water inlet at the top side of the top spray arm 3 is rotatably connected to the bottom end of the vertical section 402.

[0026] In this embodiment, a mounting post 41, coaxially arranged with the vertical section 402, protrudes from the side wall of the top side of the connecting pipe 4. The mounting post 41 extends upward through the relief hole 11 and into the outer side of the inner liner 2. The protrusion 121 surrounds the outer periphery of the top of the mounting post 41, thereby hiding the mounting post 41 and improving aesthetics. The mounting post 41 has an axially extending blind mounting hole 411 corresponding to the mounting opening 1211. The connecting pipe 4 and the inner liner 1 are connected to each other through the blind mounting hole 411 of the mounting post 41 and the mounting hole 1211 of the mounting bracket 12 and fixed with screws. The outer peripheral wall of the mounting post 41 has a boss 42 that extends outward and then upward. The boss 42 and the outer peripheral wall of the mounting post 41 surround and form an upward-opening annular groove 421. A sealing ring 43 is embedded in the annular groove 421. The sealing ring 43 abuts against the top wall of the inner liner 1 located on the outer periphery of the relief hole 11, thereby achieving a sealing fit between the mounting post 41 and the top wall of the inner liner 1.

[0027] The working principle of this embodiment is as follows: During installation, first connect the inner water pipe 2 and the top spray arm 3 through the connecting pipe 4, then align the mounting post 41 on the top side of the connecting pipe 4 with the clearance hole 11 and insert it, and finally thread the screw through the mounting hole 1211 and connect it in the mounting blind hole 411 until the end face of the top of the connecting pipe 4 abuts against the top wall of the protrusion 121, thus completing the connection between the connecting pipe 4 and the top wall of the inner tank 1;

[0028] This solution expands the function of the connecting pipe 4, enabling it to connect the inner water pipe 2, the top spray arm 3, and the inner tank 1 simultaneously. This reduces the installation dimensions of the top spray arm 3, improves the accuracy of its installation position, and is more conducive to its stable movement, reducing shaking.
