Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a water distribution structure for a washing machine used for washing tableware, fruits and vegetables and a washing machine. Background Art

[0002] Dishwashers are widely used in home kitchens. In order to improve the cleaning effect, many dishwashers are currently equipped with two sets of upper and lower spray arms. The upper spray arm in the dishwasher is usually fixed on the upper bowl basket and connected to the inner water pipe through a connecting water pipe.

[0003] For example, the Chinese patent "Water distribution structure, internal water pipe structure and dishwasher" (application number: CN202121506706.7) with authorization announcement number CN215191361U discloses a structure suitable for an internal water pipe, and the side wall of the water outlet end of the internal water pipe is provided with a water outlet, and the water distribution structure includes: a ball storage tank, which is arranged on the inner water pipe and located above the water outlet, and the outer side of the ball storage tank is a closed structure; a water distribution ball is configured to be able to move between the ball storage tank and the water outlet, and can move from the position of the water outlet to the ball storage tank under the action of water pressure, and move from the ball storage tank to the water outlet when the water pressure at the water outlet drops, and close the water outlet under the action of water pressure.

[0004] The upper spray arm is connected to the inner water pipe through a water pipe joint, and the water pipe joint is connected to the inner water pipe by a plug-in connection. Although such a structure is relatively simple and convenient to connect, since the water pipe joint needs to bear a large amount of water conduction, if the water pipe joint sags under gravity, it is easy to cause water leakage here, affecting the normal water supply of the upper spray arm. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a water distribution structure for a cleaning machine with convenient connection and good sealing performance in view of the current status of the prior art.

[0006] The second technical problem to be solved by the utility model is to provide a cleaning machine with the above-mentioned water distribution structure in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve at least one of the above technical problems is:

[0008] A water distribution structure for a cleaning machine includes an inner water pipe and a water receiving pipe, wherein the inner water pipe is arranged vertically and a water outlet is provided on the side wall, and the water receiving pipe is arranged horizontally and a water inlet port is connected to the water outlet. An inclined surface is formed on the side wall of the inner water pipe around the water outlet and gradually tilted from top to bottom toward the water receiving pipe. A slot is provided on the periphery of the inclined surface. Accordingly, the water inlet port of the water receiving pipe forms an inclined edge that can cooperate with the inclined surface and is detachably connected to the slot.

[0009] Preferably, a U-shaped bracket is disposed on the outer periphery of the inclined surface, surrounding the water outlet and opening upward, and the water inlet end of the water receiving pipe is supported in the bracket in the assembled state. With the above structure, the water receiving pipe is always supported by the bracket, and even if the water receiving pipe sinks slightly due to the weight of the water during use, it will be positioned by the bracket, thereby ensuring the sealing here.

[0010] Preferably, the front edge of the bottom of the bracket extends forward and upward to form an arc-shaped sleeve that can surround the lower surface of the water receiving pipe. This structure not only improves the supporting effect on the bottom of the water receiving pipe, but also cooperates with the U-shaped bracket to form a deeper slot and improve the reliability of the limit of the spray arm.

[0011] Preferably, the slot is formed at the junction of the bottom of the bracket and the arc sleeve, and the bottom wall of the slot is provided with an opening. With the above structure, if a small amount of water leaks between the water receiving pipe and the inner water pipe due to factors such as aging over a long period of time, it can also be drained away in time through the opening at the bottom of the slot to avoid bacterial growth.

[0012] Preferably, the bottom edge of the water receiving pipe is provided with a convex card that can be inserted into the card slot. This structure facilitates the limiting connection between the bottom of the water receiving pipe and the card slot on the side of the inner water pipe, and the assembly operation is convenient.

[0013] Preferably, when the water inlet end of the water receiving pipe is inserted into the bracket from top to bottom, the bevel and the bevel are gradually pressed and sealed.

[0014] Preferably, the top edge of the U-shaped bracket is provided with guide edges extending outwards respectively, and a guide structure of an inverted figure eight structure with a large upper end and a small lower end is formed between the two guide edges. With such a structure, when the user plugs the water connection pipe into the inner water pipe, the guide edge can provide a guiding and positioning function from top to bottom for the water connection pipe, which is convenient for operation.

[0015] Preferably, when the bevel and the inclined surface are in contact with each other, a sealing ring is elastically pressed between the bevel and the inclined surface. This structure is conducive to further improving the connection sealing between the water receiving pipe and the inner water pipe.

[0016] A cleaning machine comprises a box body, a bowl rack, a spray arm and the above-mentioned water distribution structure. The bowl rack is arranged at the upper part of the washing chamber of the cleaning machine, and the spray arm is rotatably arranged under the bowl rack and is connected to a water receiving pipe constrained at the bottom of the bowl rack.

[0017] Compared with the prior art, the advantages of the utility model are: the utility model is provided with an inclined surface on the side wall of the inner water pipe, which is gradually inclined from top to bottom around the water outlet and toward the water receiving pipe, and a card groove is provided on the periphery of the inclined surface. The water inlet port of the water receiving pipe is docked with the inclined surface through the corresponding inclined edge and is detachably connected with the card groove. The whole connection structure is simple and reasonable, and the operation is convenient. In addition, the coordination between the inclined surface and the inclined edge can automatically press the contact surface when the water receiving pipe moves slightly downward due to gravity, thereby improving the sealing performance.

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5 As shown, the water distribution structure for the cleaning machine of this embodiment includes an inner water pipe 1 and a water receiving pipe 2. The inner water pipe 1 is arranged vertically and a water outlet 11 is opened on the side wall. The water receiving pipe 2 is arranged horizontally and a water inlet port is connected with the water outlet 11. The side wall of the inner water pipe 1 is formed with an inclined surface 12 around the water outlet 11, which is gradually inclined from top to bottom toward the water receiving pipe 2. A groove 13 is arranged on the periphery of the inclined surface 12. Correspondingly, the water inlet port of the water receiving pipe 2 is formed with a bevel 21 that can cooperate with the bevel 12 and is detachably connected with the groove 13.

[0025] Specifically, a U-shaped bracket 14 is disposed on the outer periphery of the inclined surface 12, surrounding the water outlet 11 and opening upward. In the assembled state, the water inlet end of the water receiving pipe 2 is supported in the bracket 14. With the above structure, the water receiving pipe 2 is always supported by the bracket 14. Even if the water receiving pipe 2 sinks slightly due to the weight of the water body during use, it will be positioned by the bracket 14, thereby ensuring the sealing performance here.

[0026] The front edge of the bottom of the bracket 14 extends forward and upward to form an arc-shaped sleeve 15 that can surround the lower surface of the water connection pipe 2. This structure improves the supporting effect on the bottom of the water connection pipe 2 on the one hand, and on the other hand, cooperates with the U-shaped bracket 14 to facilitate the formation of a deeper slot 13, thereby improving the reliability of the limit of the spray arm.

[0027] The slot 13 is formed at the junction of the bottom of the bracket 14 and the arc sleeve 15, and the bottom wall of the slot 13 is provided with an opening 131. With the above structure, if a small amount of water leaks between the water receiving pipe 2 and the inner water pipe 1 due to factors such as aging over a long period of time, it can also be drained away in time through the opening 131 at the bottom of the slot 13 to avoid bacterial growth.

[0028] The bottom edge of the water receiving pipe 2 is provided with a convex card 22 which can be inserted into the card slot 13. This structure facilitates the limiting connection between the bottom of the water receiving pipe 2 and the card slot 13 on the side of the inner water pipe 1, and the assembly operation is convenient.

[0029] When the water inlet end of the water receiving pipe 2 is inserted into the bracket 14 from top to bottom, the bevel 21 and the bevel 12 are gradually pressed and sealed.

[0030] The top edge of the U-shaped bracket 14 is provided with guide edges 141 extending outwards respectively, and a guide structure of an inverted figure eight structure with a large upper end and a small lower end is formed between the two guide edges 141. With such a structure, when the user plugs the water connection pipe 2 into the inner water pipe 1, the guide edges 141 can provide a guiding and positioning function from top to bottom for the water connection pipe 2, which is convenient for operation.

[0031] When the bevel 21 is in contact with the bevel 12, a sealing ring 3 is elastically pressed between the bevel 21 and the bevel 12. This structure is beneficial to further improve the connection sealing between the water receiving pipe 2 and the inner water pipe 1.

[0032] The cleaning machine of this embodiment includes a housing 4, a bowl rack 5, a spray arm 6 and the above-mentioned water distribution structure. The bowl rack 5 is arranged at the upper part of the washing chamber of the cleaning machine, and the spray arm 6 is rotatably arranged under the bowl rack 5 and is connected to the water receiving pipe 2 constrained at the bottom of the bowl rack 5.

[0033] In this embodiment, a slope 12 is provided on the side wall of the inner water pipe 1, which is gradually inclined from top to bottom around the water outlet 11 toward the water receiving pipe 2. A clamping groove 13 is provided on the periphery of the slope 12. The water inlet port of the water receiving pipe 2 is docked with the slope 12 through the corresponding oblique edge 21 and is detachably connected with the clamping groove 13. The entire connection structure is simple and reasonable, and the operation is convenient. In addition, the coordination between the slope 12 and the oblique edge 21 can automatically press the contact surface of the water receiving pipe 2 when it moves slightly downward due to gravity, thereby improving the sealing performance.
