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 mounting area at the bottom. The bottom of the mounting area has a drain outlet. The machine also includes a pulsator seat, a pulsator, and a drive component. The pulsator seat is supported in the mounting area, and a first water passage gap is formed between its edge and the side wall of the mounting area. A water passage outlet is formed in the center of the pulsator seat. The pulsator is rotatably mounted on the pulsator seat, and a second water passage gap is formed between the pulsator seat and the upper surface of the pulsator seat, connecting it to the mounting area through the water passage outlet. The drive component is located at the bottom of the housing, and its output shaft passes through the water passage outlet and is connected to the pulsator.

[0008] With the above structure, after cleaning, some water in the washing chamber flows from the edge through the first water passage gap into the installation area and then out through the drain outlet. Some water flows from the center of the impeller through the second water passage gap and the water outlet into the installation area and then out through the drain outlet. The water flows into the installation area from multiple directions and washes the impeller seat during the flow. This not only facilitates the timely discharge of accumulated water but also solves the problem of local residue accumulation, thereby avoiding secondary pollution and improving the cleaning effect.

[0009] Preferably, the impeller seat is formed with a first arc-shaped structure that gradually arches downwards from the edge to the center, the water inlet is located at the lowest point of the first arc-shaped structure, and the lower surface of the impeller forms a second arc-shaped structure that matches the first arc-shaped structure. With this structure, both the first and second arc-shaped structures can better guide the water flow, and the second water passage formed between them is also arc-shaped. Combined with the suction of the drainage component, this improves drainage efficiency and prevents residue accumulation.

[0010] Preferably, the installation area extends along the length of the housing, and there are at least two sets of impeller seats and impellers, with the two impellers arranged at intervals along the length of the installation area, and the impeller seats corresponding to the two impellers connected to each other. This structure enhances water flow turbulence and further improves the cleaning effect.

[0011] Preferably, the two impeller seats are formed as a single unit, and a protruding ridge extending along the width of the installation area is formed at the joint of the two impeller seats. The upper surfaces of the two impeller seats on both sides of the protruding ridge gradually slope downward from the ridge towards the edge of the first arc-shaped structure to form a guide surface. This structure improves the integration of the components, facilitating assembly and further enhancing drainage efficiency while preventing residue accumulation.

[0012] Preferably, the impeller includes a disc-shaped body that gradually arches downwards from the edge to the center, forming the second arc-shaped structure. The upper surface of the body is provided with a first blade and a second blade extending radially, the first blade and the second blade being spaced apart. More preferably, the first blade extends radially through the impeller, the length of the second blade is less than the length of the first blade, and the circumferential width of the second blade is less than the width of the first blade. This structure is beneficial for improving the turbulence effect of the water flow.

[0013] To facilitate the installation of the impeller seat, a vertically extending protrusion is provided at the bottom of the installation area near its edge, and correspondingly, a connecting sleeve that can be detachably connected to the protrusion is provided on the lower surface of the impeller seat.

[0014] As an improvement, the housing is equipped with a washing basket located above the installation area. This washing basket contains a rotating basket that corresponds to the impeller and rotates with the impeller while it is rotating. Two sets of rotating baskets can be installed in one washing basket, each corresponding to the impeller below, which facilitates the sorting and washing of fruits and vegetables and creates dual turbulence, improving the washing effect.

[0015] Preferably, the bottom of the rotating basket is rotatably supported on the bottom wall of the washing basket. The rotating basket is cylindrical, and the bottom wall of the rotating basket is provided with radially arranged baffles. Each baffle corresponds to one of the blades of the impeller below it, so that the rotating basket rotates stably and reliably under the influence of the water flow through the agitation of the impeller.

[0016] To facilitate installation and assembly, the bottom of the cleaning basket is provided with a shaft hole. Correspondingly, the central part of the bottom wall of the rotating basket is provided with a shaft that passes downward through the shaft hole, and the lower end of the shaft is provided with a limiting flange that can cooperate with and limit the lower surface of the cleaning basket.

[0017] Compared with the prior art, the advantages of this utility model are as follows: This utility model has an integrated drive and guide structure at the bottom of the washing chamber that cooperates with the installation area. After washing, some of the water in the washing chamber flows from the edge through the first water passage gap into the installation area and then out through the drain outlet. Some of the water flows from the center of the impeller through the second water passage gap and the water passage into the installation area and then out through the drain outlet. The water flows into the installation area from multiple directions and washes the impeller seat during the flow. This not only facilitates the timely discharge of accumulated water, but also solves the problem of local residue accumulation, so as to avoid secondary pollution and improve the cleaning effect.

[0026] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this invention are for illustrative purposes only and do not represent the only possible implementation.

[0030] like Figures 1 to 6 As shown, the fruit and vegetable washing machine of this embodiment includes a box body 1. The bottom of the box body 1 is provided with a recessed installation area 11. The bottom of the installation area 11 is provided with a drain outlet 12. The outer bottom of the box body 1 is provided with a drain valve pump assembly 5 connected to the drain outlet 12 to control the opening and closing of the drain outlet 12 and provide drainage suction in the drainage state.

[0031] The fruit and vegetable washing machine of this embodiment also includes a pulsator seat 2, a pulsator 3, and a drive component 4. The pulsator seat 2 is supported in the installation area 11 and a first water passage gap 10 is formed between its edge and the side wall of the installation area 11. A water passage 21 is opened in the central part of the pulsator seat 2. The pulsator 3 is rotatably mounted on the pulsator seat 2 and a second water passage gap 20 is formed between it and the upper surface of the pulsator seat 2, which is connected to the installation area 11 through the water passage 21. The drive component 4 is a motor, which is located at the bottom of the housing 1 and the output shaft 41 passes through the water passage 21 and is connected to the pulsator 3.

[0032] With the above structure, after cleaning, some water in the washing chamber flows from the edge through the first water passage 10 into the installation area 11 and then out through the drain outlet 12. Some water flows from the center of the impeller 3 through the second water passage 20 and the water outlet 21 into the installation area 11 and then out through the drain outlet 12. The water flows into the installation area 11 from multiple directions and washes the impeller seat 2 during the flow. This not only facilitates the timely discharge of accumulated water but also solves the problem of local residue accumulation, thereby avoiding secondary pollution and improving the cleaning effect.

[0033] The impeller seat 2 has a first arc-shaped structure 01 that gradually arches downwards from the edge to the center. The water inlet 21 is located at the lowest point of the first arc-shaped structure. The lower surface of the impeller 3 forms a second arc-shaped structure 02 that matches the first arc-shaped structure 01. With the above structure, both the first and second arc-shaped structures can better guide the water flow. Furthermore, the second water passage gap 20 formed between them is also arc-shaped. Combined with the suction of the drainage component, this helps to improve the drainage effect and avoid residue accumulation.

[0034] The installation area 11 extends along the length of the housing 1. There are at least two sets of impeller seats 2 and impellers 3, and the two impellers 3 are arranged at intervals along the length of the installation area 11. The impeller seats 2 corresponding to the two impellers 3 are connected. The above structure is beneficial to enhance water flow turbulence and further improve the cleaning effect.

[0035] The two impeller seats 2 are formed as a single unit, and a protruding ridge 22 extending along the width direction of the mounting area 11 is formed at the joint of the two impeller seats 2. The upper surfaces of the two impeller seats 2 on both sides of the protruding ridge 22 gradually slope downward from the protruding ridge towards the edge of the first arc-shaped structure to form a guide surface 23. By adopting the above structure, the integration of the components is improved, which not only facilitates assembly but also helps to further improve drainage efficiency and avoid residue accumulation.

[0036] The impeller 3 includes a disc-shaped body 33, which gradually arches downward from the edge to the center to form a second arc-shaped structure. The upper surface of the body 33 is provided with a first blade 31 and a second blade 32 extending radially, with the first blade 31 and the second blade 32 arranged at intervals. More preferably, the first blade 31 extends radially through the impeller, the length of the second blade 32 is less than the length of the first blade 31, and the circumferential width of the second blade 32 is less than the width of the first blade 31. This structure is beneficial for improving the turbulence effect of the water flow.

[0037] To facilitate the installation of the impeller seat 2, a protruding post 111 extending vertically near its edge is provided at the bottom of the installation area 11. Correspondingly, a connecting sleeve 24 that can be detachably connected to the protruding post 111 is provided on the lower surface of the impeller seat 2.

[0038] The housing 1 contains a washing basket 6 located above the installation area 11. The bottom and side walls of the washing basket 6 are hollowed-out. A rotating basket 7, corresponding to the impeller 3 and rotating with it while the impeller 3 is rotating, is installed within the washing basket 6. The bottom and side walls of the rotating basket 7 are also hollowed-out. Two sets of rotating baskets 7 can be installed in one washing basket 6, each corresponding to the impeller 3 below, facilitating the sorting and washing of fruits and vegetables and creating dual turbulence to improve the washing effect.

[0039] The bottom of the rotating basket 7 is rotatably supported on the bottom wall of the washing basket 6. The rotating basket 7 is cylindrical, and the bottom wall of the rotating basket 7 is provided with baffles 71 arranged radially. Each baffle 71 corresponds to one of the blades of the impeller 3 below it, so that the impeller 3 agitates the water and drives it to rotate stably and reliably.

[0040] To facilitate installation and assembly, a shaft hole 61 is provided at the bottom of the cleaning basket 6. Correspondingly, a shaft 72 is provided at the center of the bottom wall of the rotating basket 7, which passes downward through the shaft hole 61, and a limiting flange 73 is provided at the lower end of the shaft 72 to limit its engagement with the lower surface of the cleaning basket 6.

[0041] In this embodiment, an integrated drive and guide structure that cooperates with the installation area 11 is provided at the bottom of the washing chamber. After washing, some water in the washing chamber flows into the installation area 11 from the edge through the first water passage gap and then is discharged through the drain outlet 12. Some water flows into the installation area 11 from the center of the impeller 3 through the second water passage gap 20 and the water passage 21 and then is discharged through the drain outlet 12. The water flows into the installation area 11 from multiple directions and washes the impeller seat 2 during the flow. This not only facilitates the timely discharge of accumulated water, but also solves the problem of local residue accumulation, so as to avoid secondary pollution and improve the cleaning effect.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
