Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, specifically to a fruit and vegetable washing machine. Background Technology

[0002] The common cleaning methods of fruit and vegetable washing machines are spraying water jets onto the fruits and vegetables, or creating turbulence in the water that submerges the fruits and vegetables to clean them.

[0003] Chinese invention patent ZL 202010900536.4, entitled "A Cleaning Machine," discloses a structure comprising a water tank, a cleaning basket, a spray arm, and an impeller. The cleaning basket is placed in the water tank. The spray arm has a base and an upper seat. The base is constrained in the cleaning basket and can rotate under external force. The base has an opening that runs vertically through it. The upper seat is rotatably positioned above the base and has a flow channel. The bottom wall of the upper seat has a water inlet with a corresponding opening that communicates with the flow channel, and the top wall of the upper seat has a spray hole that communicates with the flow channel. The impeller is used to draw water from below the base into the flow channel.

[0004] The above structure cleans fruits and vegetables by creating turbulence, but the drive structure components are cumbersome and the corresponding assembly structure is also relatively complicated, which makes it easy for water and residue to accumulate at the bottom of the washing chamber, affecting the cleaning effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a fruit and vegetable washing machine that can promptly drain the accumulated water and residue at the bottom of the washing chamber, thereby improving the cleaning effect, in light of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A fruit and vegetable washing machine includes a housing with a recessed water return chamber at the bottom. The bottom of the water return chamber has a water inlet and a water outlet. The water return chamber contains a first impeller and a second impeller that can rotate. The first side of the first impeller and the second impeller are arranged near the first sidewall of the water return chamber, and the second side of the first impeller and the second impeller opposite to the first side are arranged near the second sidewall of the water return chamber. The bottom wall of the water return chamber has a flow guiding structure that gradually decreases from the first sidewall to the second sidewall. The bottom wall of the water return chamber has a water inlet arranged near the first sidewall and a water outlet arranged near the second sidewall.

[0008] By adopting the above structure, with the water inlet located at a high position and the drain outlet located at a low position, it is beneficial to ensure that the water flows rapidly to all places when water enters and to quickly drain the accumulated water when draining, thereby avoiding the accumulation of residue, eliminating secondary pollution, and improving the cleaning effect.

[0009] Preferably, the return water chamber extends along the length of the tank, and both the drain outlet and the inlet are located in the middle of the return water chamber along its length. This design facilitates the rapid drainage of accumulated water.

[0010] Preferably, the bottom wall of the return water chamber has a first guide surface that gradually decreases in shape from the first side wall towards the drain outlet and has a triangular structure. The tip of the first guide surface extends towards the second side wall to form a concave ridge that symmetrically divides the two sides of the triangular structure, and the drain outlet is located on this concave ridge. This structure facilitates the rapid drainage of accumulated water.

[0011] Preferably, the bottom wall of the return water cavity on the first side of the triangular structure gradually extends downward from the edge towards the concave edge to form a second guide surface, and the bottom wall of the return water cavity on the second side of the triangular structure gradually extends downward from the edge towards the concave edge to form a third guide surface. This structure allows for rapid drainage of accumulated water in the return water cavity, increasing the drainage speed and preventing residue from accumulating at the bottom of the return water cavity.

[0012] Preferably, the first and second impellers are arranged side-by-side along the length of the return water chamber, with the inlet and outlet located between them, and the inlet positioned at the center of the first guide surface. Since the first and second impellers each generate a rotating water flow centered on itself, the two flows collide at their confluence, and the violently turbulent water flows flush the inlet and outlet to prevent residue accumulation, thereby avoiding secondary pollution and improving the cleaning effect.

[0013] Preferably, the second sidewall of the return water chamber smoothly arches outward at the corresponding second region to form a drainage area, and the outer edge of the drain outlet is arranged close to the inner wall of this drainage area. By setting the aforementioned outwardly arched drainage area, the turbulent water flow will rush along the arched sidewall, thereby rinsing the edge of the drain outlet 360 degrees, which not only avoids the accumulation of residue, but also helps to further improve the drainage effect.

[0014] Preferably, both the first and second impellers comprise a disc-shaped body, around which a first ring and a second ring are arranged concentrically and spaced apart. The outer wall of the body is provided with radially extending stirring ribs that connect the first and second rings integrally. This structure eliminates the vertical movement of water during impeller rotation, preventing the accumulation of fruits and vegetables in certain areas. Furthermore, it creates a laminar flow effect, improving the stable agitation of fruits and vegetables and thus enhancing the cleaning effect.

[0015] As an improvement, the interior of the body is hollow, forming a buffer cavity with an open bottom and a closed top. This structure further prevents water from flowing vertically within the buffer cavity.

[0016] Preferably, the bottom of the housing is provided with a drive component for rotating the first and second impellers. The output shaft of the drive component passes through the bottom wall of the housing and connects to the central part of the first and second impellers. This structure provides power for the rotation of the impellers, enabling automatic cleaning.

[0017] Compared with the prior art, the advantages of this utility model are as follows: This utility model sets up a first impeller and a second impeller arranged side by side in the return water cavity, and sets the bottom wall of the return water cavity as a flow guiding structure that gradually decreases from its first side wall to its second side wall. The water inlet is set at a high position and the water outlet is set at a low position, which is conducive to the rapid flow of water to all places when water enters and the rapid discharge of accumulated water when draining, thereby avoiding the accumulation of residue, eliminating secondary pollution, and improving the cleaning effect.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-4 As shown, the fruit and vegetable washing machine of this embodiment includes a housing 1. The bottom of the housing 1 is provided with a recessed water return cavity 11. The bottom of the water return cavity 11 has a water inlet 12 and a drain outlet 13. The water return cavity 11 is provided with a first impeller 10 and a second impeller 20 that can rotate. The first side of the first impeller 10 and the second impeller 20 is arranged close to the first side wall of the water return cavity 11. The second side of the first impeller 10 and the second impeller 20, which is opposite to the first side, is arranged close to the second side wall of the water return cavity 11. The bottom wall of the water return cavity 11 forms a flow guiding structure that gradually decreases from its first side wall to its second side wall. The bottom wall of the water return cavity 11 has a water inlet 12 arranged close to the first side wall and a drain outlet 13 arranged close to the second side wall.

[0024] By adopting the above structure, the water inlet 12 is placed at a high position and the drain outlet 13 is placed at a low position. This facilitates the rapid flow of water to all parts when water is introduced and the rapid discharge of accumulated water when draining, thereby avoiding the accumulation of residue, eliminating secondary pollution, and improving the cleaning effect.

[0025] The return water chamber 11 extends along the length of the tank body 1, and the drain outlet 13 and the inlet 12 are both located in the middle of the length of the return water chamber 11. This design facilitates the rapid drainage of accumulated water.

[0026] The bottom wall of the return water chamber 11 has a first guide surface 01 that gradually decreases from the first side wall toward the drain outlet 13 and has a triangular structure. The tip of the first guide surface 01 extends toward the second side wall to form a concave ridge 011 that symmetrically divides the two sides of the triangular structure. The drain outlet 13 is located on the concave ridge 011. This structure facilitates the rapid drainage of accumulated water.

[0027] The bottom wall of the return water cavity 11 on the first side of the triangular structure gradually extends downward from the edge towards the concave edge 011 to form a second guide surface 02, and the bottom wall of the return water cavity 11 on the second side of the triangular structure gradually extends downward from the edge towards the concave edge 011 to form a third guide surface 03. This structure is used to quickly guide the accumulated water in the return water cavity 11, increase the water discharge speed, and prevent residue from accumulating at the bottom of the return water cavity 11.

[0028] The first impeller 10 and the second impeller 20 are arranged side by side along the length of the return water chamber 11. The inlet 12 and the outlet 13 are both located between the first impeller 10 and the second impeller 20, with the inlet 12 located at the center of the first guide surface 01. Since the first impeller 10 and the second impeller 20 will each generate a rotating water flow centered on itself, the two water flows collide with each other at the confluence point. The violently turbulent water flow will flush the inlet and outlet 13 to avoid the accumulation of residue, thereby avoiding secondary pollution and improving the cleaning effect.

[0029] The second sidewall of the return water chamber 11 smoothly arches outward at the corresponding second region to form a drainage area 14, and the outer edge of the drain outlet 13 is arranged close to the inner wall of the drainage area 14. By setting the aforementioned outwardly arched drainage area 14, the turbulent water flow will rush along the arched sidewall, thereby rinsing the edge of the drain outlet 13 360 degrees, which not only avoids the accumulation of residue, but also helps to further improve the drainage effect.

[0030] Both the first impeller 10 and the second impeller 20 include a disc-shaped body 101. A first ring 102 and a second ring 103, spaced apart and concentrically arranged, are fitted around the body 101. The outer wall of the body 101 is provided with radially extending stirring ribs 100 that connect the first ring 102 and the second ring 103 to the body 101. With this structure, there is no vertical water flow during impeller rotation, thus avoiding the problem of localized accumulation of fruits and vegetables. Furthermore, a laminar flow effect is created, improving the stable stirring effect on fruits and vegetables, thereby enhancing the cleaning effect.

[0031] The body 101 has a hollow interior forming a buffer cavity 105 with an open bottom and a closed top. With this structure, the water stored in the buffer cavity can further prevent the formation of water flow that moves up and down.

[0032] The bottom of the housing 1 is equipped with a drive unit, which is a motor, for driving the first impeller 10 and the second impeller 20 to rotate. The output shaft 2 of the drive unit passes through the bottom wall of the housing 1 and is connected to the central part of the first impeller 10 and the second impeller 20. This structure provides power for the rotation of the impellers to achieve automatic cleaning.

[0033] In this embodiment, a first impeller 10 and a second impeller 20 are arranged side by side in the return water chamber 11, and the bottom wall of the return water chamber 11 is configured as a flow guide structure that gradually decreases from its first side wall to its second side wall. The water inlet 12 is set at a high position and the water outlet 13 is set at a low position, which is conducive to the rapid flow of water to all places when water enters and the rapid discharge of accumulated water when draining, thereby avoiding the accumulation of residue, eliminating secondary pollution, and improving the cleaning effect.
