Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dishwashers, in particular to a cleaning machine and a cleaning method for cleaning tableware and fruits and vegetables. BACKGROUND

[0002] With the increasing improvement of people's living standards, dishwashers as a kind of kitchen household electrical products are increasingly entering families. The dishwashers on the market are generally divided into three types: table type, cabinet type and tank type. Among them, the table type dishwasher is a whole independent structure, which is generally placed on the table for use; the cabinet type dishwasher is also an independent structure, but needs to be embedded in the kitchen cabinet for use; the tank type dishwasher is combined with the sink, which is generally installed in the kitchen cabinet for use.

[0003] The prior patent ZL202221185181.6 "A cleaning machine" of the present applicant discloses a structure, which includes a box body, a flow guide seat and a slag collecting basket. The bottom of the box body is provided with a concave water return area. The top of the water return area is covered with a filter plate. The bottom of the flow guide seat is supported in the water return area for conveying water in the water return area to the top of the filter plate. The lower part of the slag collecting basket is accommodated in the water return area through the filter plate, and the upper part of the slag collecting basket is exposed above the filter plate. Part of the edge of the water return area forms a flow guide structure which is outwardly arched and arranged in a circumferential spiral. The slag collecting basket is arranged close to the flow guide structure. The lower end of the flow guide seat is closed, and the sidewall is provided with a water suction port corresponding to the arrangement of the slag collecting basket and the flow guide structure.

[0004] In the above-mentioned structure of the cleaning machine, the flow guide seat adopts a single aggregation type water suction port structure, which is beneficial to improve the water suction efficiency and the slag collecting efficiency. However, due to the complex washing environment during the washing process, affected by the properties of the detergent and the objects to be cleaned, a large amount of foam may be generated as the cleaning time is prolonged. The generation of foam not only affects the effective washing water volume, leading to a decrease in liquid level, but also makes the foam easy to be sucked into the spray arm, affecting the jet lift and pressure, and further affecting the cleaning effect. Moreover, the water flow speed through the center of the slag collecting basket is significantly reduced, resulting in poor slag collecting effect. SUMMARY

[0005] The first technical problem to be solved by the present application is to provide a cleaning machine which can automatically adjust the water suction height according to the properties of the washing water, thereby improving the water flow speed and further improving the cleaning effect and the slag collecting effect, in view of the current status of the prior art.

[0006] The second technical problem to be solved by the present application is to provide a cleaning method of the above-mentioned cleaning machine, in view of the current status of the prior art.

[0007] The technical solution adopted by the present application to solve at least one of the above technical problems is as follows:

[0008] A cleaning machine comprises a tank, a water pump and a slag collecting basket, the tank is provided with a concave backwater area at the bottom, the top of the backwater area is covered with a filter plate, the water pump is arranged in the backwater area, the lower part of the slag collecting basket is accommodated in the backwater area, the top of the slag collecting basket is provided with a slag collecting opening exposed above the filter plate, the water pump is provided with a baffle extending towards the side of the slag collecting basket to form an aggregated water suction channel, and an adjusting ring is sleeved on the outer periphery of the slag collecting basket and can move up and down under the action of the washing water buoyancy to restrict the water suction height in cooperation with the baffle.

[0009] Preferably, the bottom of the backwater area is provided with a concave backflow area for mounting the water pump and the slag collecting basket, the water pump and the slag collecting basket are arranged side by side in the backflow area, the side wall of the backflow area is arranged close to the outer periphery of the water pump and the slag collecting basket, and the baffle cooperates with the side wall of the backflow area to enclose a single aggregated water suction channel. With the above structure, a single aggregated water suction channel is formed, which can better restrict the water suction height.

[0010] In the present application, the height from the lower surface of the baffle to the inner bottom wall of the backflow area constitutes a fixed water suction height H. In the initial washing stage, when there is no foam in the washing water, the adjusting ring is located above the height H, and the water suction height can be considered to adopt the above-mentioned fixed water suction height, but the water suction area is slightly larger than the water suction area corresponding to the fixed water suction height.

[0011] Preferably, the adjusting ring is sleeved on the outer peripheral wall of the slag collecting basket, the maximum height of the adjusting ring floating relative to the inner bottom wall of the backflow area is H1, and the minimum height of the adjusting ring floating relative to the inner bottom wall of the backflow area is H2, the floating water suction height is restricted by (H1-H2), and H2≤H≤H1. With such arrangement, the water suction height is reasonably adjusted within a certain range, so as to meet the requirements of the backwater flow rate and the flow rate of the water flow through the central passage of the slag collecting basket, so as to improve the jet height and lift, and improve the slag collecting effect.

[0012] Preferably, a first limiting part capable of cooperating with the top edge of the adjusting ring to restrict it at H1 is arranged on the outer peripheral wall of the slag collecting basket, and a second limiting part capable of cooperating with the bottom edge of the adjusting ring to restrict it at H2 is arranged on the outer peripheral wall of the slag collecting basket. In order to avoid the adjusting ring from being out of control due to changes in the washing environment in the washing cavity, the above structure is arranged to always restrict the adjusting ring between the first limiting part and the second limiting part.

[0013] Preferably, the adjusting ring is annular and internally hollow to form a floating cavity, and the outer peripheral wall of the adjusting ring is arranged close to the inner side wall of the backflow area and the edge of the baffle to restrict a water suction area below the adjusting ring. The inner wall of the adjusting ring is annular and matches the outer side wall of the slag collecting basket, and the outer side wall of the adjusting ring forms a outwardly arched protrusion which is in sealing engagement with the inner side wall of the backflow area and the edge of the baffle. The above structure is advantageous to restrict a relatively independent water suction area and avoid water suction in other positions to cause water flow disorder.

[0014] Preferably, the adjusting ring comprises a first part and a second part which are connected in sequence, the second part has a greater width in the radial direction than the first part, and the lower surface of the second part is gradually inclined upward in the radial direction from inside to outside to form a floating surface which is in contact with the washing water. The above structure forms a larger floating surface and is advantageous to improve the floating stability of the adjusting ring.

[0015] In the present application, the bottom of the backflow area is provided with a water outlet, the outer bottom of the tank is provided with a water drainage power assembly which is in communication with the water outlet, and the bottom of the slag collecting basket is in communication with the water outlet.

[0018] In the initial state of washing, there is no or little foam in the washing water, the adjusting ring is floated above the baffle under the large floating force of the washing water, and a large water suction height is maintained;

[0019] After a period of washing, as the foam in the washing water increases, the water level of the washing water decreases, the floating force of the washing water on the adjusting ring decreases, and the adjusting ring automatically adjusts the floating height under the double balancing action of the floating force of the washing water and the gravity to reduce the water suction height and improve the water suction flow rate, and to avoid that the foam is sucked into the water pump.

[0020] Preferably, as the washing time is prolonged, when the automatic floating displacement of the adjusting ring cannot meet the requirement of the water suction flow rate, the water suction power of the water pump is increased, so that the water suction power of the water pump, the floating force of the washing water and the gravity of the adjusting ring are balanced together to further reduce the height of the adjusting ring, reduce the water suction height and improve the water suction flow rate.

[0021] Compared with the prior art, the water pump of the present application cooperates with the slag collecting basket to form an aggregated water suction channel, thus improving the water suction efficiency and the slag collecting effect; meanwhile, the adjusting ring capable of floating up and down under the action of the washing water is arranged on the outer periphery of the slag collecting basket, and the water level of the washing water and the content of the foam in the washing water will affect the buoyancy of the adjusting ring, thus the adjusting ring can automatically adjust the water suction height according to the properties of the washing water, when there is no or little foam, the water suction height is increased, the water flow can pass through the slag collecting basket at a larger flow rate, when there is much foam, the water suction height is decreased, the water flow can still pass through the slag collecting basket at a larger flow rate, thus improving the slag collecting effect, the jet flow lift and the pressure, and thus improving the cleaning effect.

[0028] The present application will be further described in detail below with reference to the embodiments of the drawings.

[0029] As shown in Fig. Figure 1 6, the cleaning machine of the present embodiment comprises a box body 1, a water pump 2 and a slag collecting basket 3, the bottom of the box body 1 is provided with a concave backwater area 11, the top of the backwater area 11 is covered with a filter plate 12, the water pump 2 is arranged in the backwater area 11, the bottom of the water pump 2 is provided with a water suction port, and the top of the water pump 2 is provided with a water outlet port, a spray arm 6 connected with the water outlet port of the water pump 2 is arranged above the filter plate 12.

[0030] The lower part of the slag collecting basket 3 is contained in the backwater area 11, the top of the slag collecting basket 3 is provided with a slag collecting opening 31 exposed above the filter plate 12, and the water pump 2 is provided with a baffle plate 22 extending towards the side of the slag collecting basket 3 to form a concentrated water suction channel 21. The outer periphery of the slag collecting basket 3 is sleeved with an adjusting ring 4 which can move up and down under the buoyancy of the washing water to cooperate with the baffle plate 22 to restrict the water suction height.

[0031] Specifically, the bottom of the backwater area 11 is provided with a concave backflow area 13 for installing the water pump 2 and the slag collecting basket 3, the water pump 2 and the slag collecting basket 3 are arranged side by side in the backflow area 13, the side wall of the backflow area 13 is arranged close to the outer periphery of the water pump 2 and the slag collecting basket 3, and the baffle plate 22 cooperates with the side wall of the backflow area 13 to enclose a single concentrated water suction channel. The single concentrated water suction channel only sucks water on the side of the baffle plate 22, and other parts of the slag collecting basket 3 are blocked by the inner wall of the backflow area 13 and basically have no water exchange. The single concentrated water suction channel can better restrict the water suction height.

[0032] In the present embodiment, the height from the lower surface of the baffle plate 22 to the inner bottom wall of the backflow area 13 constitutes a fixed water suction height H. In the initial washing stage, when there is no foam in the washing water, the adjusting ring 4 is located above the height H, the water suction height can be considered to adopt the above-mentioned fixed water suction height, but the water suction area is slightly larger than the water suction area corresponding to the fixed water suction height. The adjusting ring 4 is sleeved on the outer peripheral wall of the slag collecting basket 3, the adjusting ring 4 floats to a maximum height H1 relative to the inner bottom wall of the backflow area 13, and the adjusting ring 4 sinks to a minimum height H2 relative to the inner bottom wall of the backflow area 13, (H1-H2) restricts a floating water suction height, and H2≤H≤H1. With such a setting, the water suction height is reasonably adjusted within a certain range, so as to meet the requirements of the backwater flow rate and the flow rate of the water flow through the central channel of the slag collecting basket, so as to improve the jet height and lift, and improve the slag collecting effect.

[0033] The outer peripheral wall of the slag collecting basket 3 is provided with a first limiting portion 301 which can cooperate with the top edge of the adjusting ring 4 to restrict it at H1, and the outer peripheral wall of the slag collecting basket 3 is provided with a second limiting portion 302 which can cooperate with the bottom edge of the adjusting ring 4 to restrict it at H2. In order to avoid the adjusting ring 4 from being out of control due to changes in the washing environment in the washing cavity, the above structure is provided, so that the adjusting ring 4 is always restricted between the first limiting portion 301 and the second limiting portion 302.

[0034] In the embodiment, the adjusting ring 4 is annular and internally hollow to form a floating cavity 40, and the outer peripheral wall of the adjusting ring 4 is arranged close to the inner side wall of the backflow area 13 and the edge of the baffle 22 to restrict a water suction area 400 below the adjusting ring 4. The inner wall of the adjusting ring 4 is annular and matches the outer side wall of the slag collecting basket 3, and the outer side wall of the adjusting ring 4 forms an outwardly arched protrusion 43 which is in sealing cooperation with the inner side wall of the backflow area 13 and the edge of the baffle 22. The above structure is beneficial to restrict a relatively independent water suction area 400 and avoid water suction in other positions to cause water flow disorder.

[0035] In the embodiment, the bottom of the backflow area 13 is provided with a water outlet 131, and the outer bottom of the box body 1 is provided with a water suction power assembly 5 which is in communication with the water outlet 131, and the bottom of the slag collecting basket 3 is in communication with the water outlet 131.

[0036] The cleaning method of the cleaning machine in the embodiment includes the following steps:

[0037] Water is fed into the box body 1, and after the water feeding is completed, the washing is started;

[0038] In the initial state of washing, there is no or little foam in the washing water, the adjusting ring 4 floats above the baffle 22 under the large floating force of the washing water, and a large water suction height is maintained;

[0039] After a period of washing, as the foam in the washing water increases, the water level of the washing water decreases, the floating force of the washing water on the adjusting ring 4 decreases, and the adjusting ring 4 automatically adjusts the floating height under the double balancing action of the floating force of the washing water and the gravity to reduce the water suction height and improve the water suction flow rate, and to avoid that the foam is sucked into the water pump;

[0040] As the washing time is prolonged, when the automatic floating displacement of the adjusting ring 4 cannot meet the water suction flow rate requirement (the water flow rate can be judged by the output power of the water pump 2, and an independent water flow rate detector can be arranged on the inner side of the slag collecting basket to judge the water flow rate), the water suction power of the water pump 2 is increased, so that the water suction power of the water pump 2, the floating force of the washing water and the gravity of the adjusting ring 4 are balanced together to further reduce the height of the adjusting ring 4, reduce the water suction height and improve the water suction flow rate.

[0041] The water pump 2 of the embodiment cooperates with the slag collecting basket 3 to form a concentrated water suction channel, thereby improving water suction efficiency and slag collecting effect; meanwhile, the adjusting ring 4 capable of floating up and down under the action of washing water is arranged on the outer periphery of the slag collecting basket 3, and since the water level of washing water and the content of foam in washing water will affect the buoyancy of the adjusting ring 4, the adjusting ring 4 can automatically adjust the water suction height according to the properties of washing water, when there is no or little foam, the water suction height is increased, the water flow can pass through the slag collecting basket 3 at a larger flow rate, when there is much foam, the water suction height is decreased, the water flow can still pass through the slag collecting basket 3 at a larger flow rate, thereby improving the slag collecting effect, and improving the jet flow lift and pressure, thereby improving the cleaning effect.
