Description

Technical Field

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

[0002] Dishwashers have been widely used in home kitchens.

[0003] The applicant's prior application 202410044765.9 "A cleaning machine" discloses a structure including a water cup and a water pump, the water cup is provided with a concave water return area, the water pump is arranged close to the local inner wall of the water return area, the bottom of the water pump is provided with a water suction port arranged opposite to the local inner wall and facing the water return area, and the upper surface of the water pump is provided with a diversion structure extending gradually downward from the middle to the edge. The above scheme also reduces or eliminates the problem of easy suction of the water pump suction port by providing a water retaining rib at the bottom of the water pump.

[0004] Although the above-mentioned prior solution seems to divide the water suction area of ​​the water pump into two parts corresponding to the slag basket and the heating element, the water suction height of the two parts is actually equal. Since a large amount of return water flows back through the slag basket and a small amount of return water flows back through the heating element, the water suction speed on the slag basket side is much higher than the water suction speed on the heating element side, and the problem of empty suction is still easy to occur, which affects the water return effect to a certain extent. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a cleaning machine which can effectively avoid the vacuum problem and thus improve the water return effect in view of the current status of the prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problems is:

[0007] A cleaning machine comprises a box body and a water pump, wherein a concave water return area is arranged at the bottom of the box body, the water pump is arranged in the water return area and has a water inlet at the bottom, a heating element and a slag collecting basket arranged adjacent to the water pump are also arranged in the water return area, and a downwardly extending water retaining rib is arranged at the bottom of the water pump, the water retaining rib constrains a first water absorption height corresponding to the slag collecting basket and a second water absorption height corresponding to the heating element, and the first water absorption height is greater than the second water absorption height.

[0008] The utility model clearly distinguishes the water absorption heights of different return water areas through water retaining ribs, positions the water absorption height of the corresponding slag collecting basket at the first water absorption height, and positions the water absorption height of the corresponding heating element at the second water absorption height, and the first water absorption height is greater than the second water absorption height. Since the amount of return water from the slag collecting basket is much greater than the amount of return water from the heating element, the above-mentioned different water absorption heights are used to use the second water absorption height as a flow sharing point at the first water absorption height, which is beneficial to reducing the flow velocity at the first water absorption height, eliminating the problem of empty suction, and thus improving the return water effect.

[0009] Preferably, on the inner top wall of the water return area supported by the bottom edge of the water retaining rib, the water retaining rib is formed into a semi-enclosed structure surrounding the water inlet, and the opening of the semi-enclosed structure is arranged corresponding to the slag collection basket. With such a structure, the main water absorption area is aligned with the slag collection basket to improve the water return efficiency.

[0010] Preferably, the first installation area of ​​the water pump and the slag basket at the bottom of the return water area is lower than the second installation area of ​​the heater, a step with a smooth transition is formed between the first installation area and the second installation area, the first side wall of the water retaining rib is arranged close to the inner wall of the return water area, and the second side wall of the water retaining rib is close to the step, thereby dividing the water suction direction of the water pump into a first water suction direction toward the slag basket and a second water suction direction toward the heater. By adopting the above scheme, a clear water suction area is divided between the slag basket and the heater, so that the main return water area corresponds to the slag basket, and the heater is only used as a return water supplement, which is not only conducive to eliminating the vacuum problem, but also conducive to improving the heating effect.

[0011] Preferably, the water retaining rib corresponding to the second water absorption direction is provided with a notch extending upward from the bottom edge, and the notch is arranged toward the heating element and constrains the second water absorption height. It is very convenient to limit the second water absorption height by the above structure, and the notch arranged close to the bottom wall of the return water area facilitates the rapid absorption of residues into the water suction port at the bottom of the water pump, and avoids the accumulation of residues in the low flow area to cause bacterial growth.

[0012] Preferably, the water retaining ribs extend beyond the bottom of the water pump, and the bottom wall of the water pump extends outwards in the area corresponding to the water retaining ribs to form a baffle, and the baffle and the water retaining ribs together constrain the first water absorption height. With such a structure, the first water absorption height can be effectively controlled, and the water absorption force of the return water from the slag collection basket can be improved.

[0013] Further preferably, the edge of the baffle extends downward to form a baffle for controlling the first water absorption height. This structure is conducive to further accurately controlling the first water absorption height and preventing bubbles from being sucked in.

[0014] Preferably, the first water absorption height is 8 to 17 mm greater than the second water absorption height. Preferably, the first water absorption height is 18 to 25 mm, and the second water absorption height is 6 to 15 mm. Controlling the first water absorption height and the second water absorption height within the above range is conducive to completely solving the vacuum absorption problem and obtaining the best water absorption effect.

[0015] Compared with the prior art, the advantages of the utility model are: the utility model clearly distinguishes the water absorption heights of different return water areas through water retaining ribs, and positions the water absorption height of the corresponding slag collecting basket at the first water absorption height, and the water absorption height of the corresponding heating element at the second water absorption height, and the first water absorption height is greater than the second water absorption height. Since the return water amount from the slag collecting basket is much greater than the return water amount from the heating element, the above-mentioned different water absorption heights are adopted, and the second water absorption height is used as the flow sharing point at the first water absorption height, which is beneficial to reduce the flow velocity at the first water absorption height, eliminate the vacuum problem, and thus improve the return water effect.

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 3 As shown, the cleaning machine of this embodiment includes a box body 1 and a water pump 2. A concave water return area 11 is provided at the bottom of the box body 1. The water pump 2 is arranged in the water return area 11 and has a water inlet 21 at the bottom. A water outlet is provided at the top of the water pump 2. A heating element 3 and a slag collection basket 4 arranged adjacent to the water pump 2 are also provided in the water return area 11. A water retaining rib 5 extending downward is provided at the bottom of the water pump 2. The water retaining rib 5 constrains a first water absorption height corresponding to the slag collection basket 4 and a second water absorption height corresponding to the heating element 3. The first water absorption height is greater than the second water absorption height.

[0021] On the inner top wall of the water return area 11 supported by the bottom edge of the water retaining rib 5, the water retaining rib 5 is formed into a semi-enclosed structure surrounding the water inlet 21, and the opening of the semi-enclosed structure is arranged corresponding to the slag collecting basket 4. With such a structure, the main water absorption area is aligned with the slag collecting basket 4 to improve the water return efficiency.

[0022] The first installation area 10 of the water pump 2 and the slag basket 4 at the bottom of the return water area 11 is lower than the second installation area 20 of the heating element 3. A smoothly transitioning step 30 is formed between the first installation area 10 and the second installation area 20. The first side wall 51 of the water retaining rib 5 is arranged close to the inner wall of the return water area 11, and the second side wall 52 of the water retaining rib 5 is close to the step 30, thereby dividing the water suction direction of the water pump 2 into a first water suction direction 01 toward the slag basket 4 and a second water suction direction 02 toward the heating element 3. By adopting the above scheme, the slag basket 4 and the heating element 3 are clearly divided into water suction areas, so that the main return water area is arranged corresponding to the slag basket 4, and the heating element 3 is only used as a return water supplement, which is not only conducive to eliminating the vacuum problem, but also conducive to improving the heating effect.

[0023] The water retaining rib 5 corresponding to the second water absorption direction 02 is provided with a notch 53 extending upward from the bottom edge, and the notch 53 is arranged toward the heating element 3 and constrains the second water absorption height. It is very convenient to limit the second water absorption height by adopting the above structure, and the notch 53 arranged close to the bottom wall of the return water area 11 facilitates the rapid absorption of residues and the like into the water absorption port 21 at the bottom of the water pump 2, and avoids the accumulation of residues in the low flow area to cause bacterial growth.

[0024] The water retaining rib 5 extends beyond the bottom of the water pump 2, and the bottom wall of the water pump 2 extends outward in the area corresponding to the water retaining rib 5 to form a baffle 54, and the baffle 54 and the water retaining rib 5 together constrain the first water absorption height. With such a structure, the first water absorption height can be effectively controlled, and the water absorption force of the return water from the slag collection basket 4 can be improved. The edge of the baffle 51 extends downward to form a retaining edge 541 for controlling the first water absorption height. This structure is conducive to further accurately controlling the first water absorption height and preventing bubbles from being sucked in.

[0025] The first water absorption height of this embodiment is 8 to 17 mm greater than the second water absorption height. The first water absorption height is 18 to 25 mm, and the second water absorption height is 6 to 15 mm. Controlling the first water absorption height and the second water absorption height within the above range is conducive to completely solving the vacuum absorption problem and obtaining the best water absorption effect.

[0026] In this embodiment, the water absorption heights of different return water areas 11 are clearly distinguished by the water retaining ribs 5, and the water absorption height corresponding to the slag collecting basket 4 is positioned at the first water absorption height, and the water absorption height corresponding to the heating element 3 is positioned at the second water absorption height, and the first water absorption height is greater than the second water absorption height. Since the amount of return water from the slag collecting basket 4 is much greater than the amount of return water from the heating element 3, the above-mentioned different water absorption heights are used to use the second water absorption height as the flow sharing point at the first water absorption height, which is beneficial to reducing the flow velocity at the first water absorption height, eliminating the vacuum problem, and thus improving the return water effect.

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.
