Description

Technical Field

[0001] The invention relates to the technical field of dishwashers, in particular to a dual-purpose washing machine which can be switched between a common water tank and a fruit and vegetable washing machine. Background Art

[0002] At present, most users generally have two sinks in their kitchens. If a sink-type dishwasher is installed, one of the sinks is used as a normal sink, and the other sink is used as a washing sink for the dishwasher. A spray system is installed in the washing sink, so it cannot be used as a normal sink.

[0003] The applicant's prior application CN202111462798.8 "A cleaning machine" discloses a structure, which includes a sink body, a water outlet and a water chamber connected below the water outlet are provided at the bottom of the sink body, and also includes a return pipe, a cover, an elastic member and a spray arm. A return pipe located next to the water outlet is provided at the bottom of the sink body, and the return pipe is provided outside the sink body and is used to connect the water chamber with the return pipe; the cover can be moved up and down at the return pipe to open or close the return pipe; the elastic member enables the cover to always maintain a tendency to move upward to close the return pipe; the spray arm is detachably provided in the sink body and arranged corresponding to the return pipe. When the spray arm and the return pipe are plugged and connected, the cover is pressed into the return pipe by the spray arm to connect the spray arm with the return pipe. When the spray arm is detached from the return pipe, the cover closes the return pipe under the drive of the elastic member.

[0004] The above solution can be used as a dishwasher or as an ordinary sink, and compared with the existing ordinary sink, the only change in the sink body is to open a water return port, the overall structure is simple and the cost of modification is low. However, since it uses a closed water pump, it needs to supply water through the return pipe, resulting in a long return path, which affects the injection head and cleaning effect.

[0005] In addition, the existing fruit and vegetable washing machines are usually equipped with a vegetable basket installed on a spray arm, and the fruits and vegetables are washed by spraying or turbulence. Since the spray hole is located at the bottom of the vegetable basket, the washing direction is single, especially in the washing of leafy vegetables, the root gaps or the stacking of leaves result in unclean washing. In the turbulent washing with a high water level, the main function of the jet is to disturb the water flow and lacks targeted cleaning, which also has the problem of unclean washing.

The slag collection basket 6 can filter the slag when used as a fruit and vegetable cleaning machine, and filter the slag when used as an ordinary water tank.

[0047] The filter plate 12 is provided with an installation opening 121 through which the top wall of the water pump mechanism 2 is exposed, and the water outlet 202 is provided on the top wall of the water pump mechanism 2 and exposed from the installation opening 121. The vegetable basket 3 is provided with an internal hollow flow channel, and the bottom of the vegetable basket 3 is provided with a water inlet 31 that can be detachably connected to the water outlet 202 of the water pump mechanism 2, and the inner wall of the vegetable basket 3 is provided with a plurality of water spray holes 32. When the vegetable basket 3 is separated from the water pump mechanism 2, the filter plate 12 and the top wall of the water pump mechanism 2 constitute part of the bottom wall of the water tank body 1.

[0048] In this embodiment, if Figures 2 to 4 As shown, a water collecting chamber 33 connected to the water inlet 31 is provided at the central part of the bottom wall of the vegetable basket 3, and a branch flow channel 34 extending from the water collecting chamber 33 to the side wall of the vegetable basket 3 is also provided on the bottom wall of the vegetable basket 3, and there are a plurality of water spray holes 32 distributed on the inner wall surface of the vegetable basket 3. This structure can spray water into the vegetable basket 3 through a larger water spraying area, and there is no side wall of the vegetable basket 3 to block the water spray directly to the fruits and vegetables in the vegetable basket 3, which is conducive to improving the cleaning effect.

[0049] There are four branch channels 34 arranged in a cross-shaped structure, each extension of the cross-shaped structure corresponds to a side wall of the basket 3, and the water spray holes 32 on the inner walls of at least two baskets 3 are arranged in different directions. With such a structure, the water spray direction is targeted at different parts, and all parts can be sprayed to eliminate dead corners in cleaning.

[0050] The projection of the vegetable basket 3 on the horizontal plane is rectangular. A branch flow channel 34 with an inverted V-shaped structure 001 is provided on the first long side wall 301 of the vegetable basket 3. A branch flow channel 34 with a V-shaped structure 002 is provided on the second long side wall 302 opposite to the first long side wall 301. A plurality of water spray holes 32 are provided in each side wall of the vegetable basket 3 along the corresponding branch flow channels 34. The branch flow channels 34 on the two opposite long side walls have opposite upper and lower arrangement trends, which is conducive to further covering a larger water spray area and improving the cleaning effect. The two short side walls 303 and 304 of the vegetable basket 3 are respectively provided with a branch flow channel 34 including a transverse portion 003 and an inclined portion 004 extending obliquely upward from the transverse portion 003. A plurality of water spray holes 32 are provided in each side wall of the vegetable basket 3 along the corresponding branch flow channels 34. This structure provides a larger water spray surface in the width direction of the vegetable basket 3 to further improve the cleaning effect.

[0051] The bottom wall of the vegetable basket 3 is provided with a drain area 35, and the drain area 35 is multiple and arranged at intervals with each extended portion of the cross-shaped structure. With such a structure, the vegetable basket 3 of this embodiment can be used as a drain basket, and the drain area 35 is in a grid shape and evenly distributed, which is conducive to improving the draining effect.

[0052] At both ends of each branch flow channel 34, at least one water spray port 36 is disposed obliquely and has a spray diameter larger than the water spray hole 32. An inclined water spray port 36 is disposed at the end of each branch flow channel 34, and the inclination trend of each water spray port 36 in the circumferential direction is consistent, so that each water spray port 36 is used to form a circulation in the vegetable basket 3 to further improve the cleaning effect.

[0053] In order to facilitate production and manufacturing, the vegetable basket 3 includes a first shell 37 and a second shell 38 that are spliced ​​with each other. The outer size of the lower part of the first shell 37 is smaller than the outer size of the upper part. The height of the second shell 38 matches the height of the lower part of the first shell 37. The second shell 38 is sleeved on the outer periphery of the first shell 37 from bottom to top, and the water collection chamber 33 and the branch flow channel 34 are arranged in the clamping compartment of the layer enclosed by the first shell 37 and the second shell 38.

[0054] It should be noted that the water spray hole in this embodiment directly sprays water columns. Of course, the diameter of the water spray hole can be increased as needed to connect a secondary water spray structure, such as a rotatable nozzle, to further increase the spraying area.

[0055] In this embodiment, if Figure 1 , 6 As shown in Figures 1 to 10, the water pump mechanism 2 includes a pump housing 21, a guide vane structure 22, an impeller 23, and a driving member 24. The pump housing 21 is roughly barrel-shaped, with a water inlet 201 opened at the bottom of the pump housing 21 and a water outlet 202 opened at the top of the pump housing 21. The guide vane structure 22 is arranged in the pump housing 21 and divides the inner cavity of the pump housing 2 into relatively independent upper cavity 211 and lower cavity 212, which is used to input the water in the lower cavity 212 into the upper cavity 211 after circumferential dispersion, and then output it upward through the water outlet 22 from the axial direction; the impeller 23 is rotatably arranged in the lower cavity 212, which is used to draw water in the return water area 11 into the lower cavity 212 and transport the water flow upward; the driving member 24 is a motor, which is arranged at the outer bottom of the water tank body 1, and the output shaft passes through the bottom wall of the water tank body 1 and is connected to the impeller 23, which is used to provide power for the rotation of the impeller 23.

[0056] The pump mechanism 2 is provided with a guide vane structure 22 and an impeller 23 in the pump housing 21 for guiding the axial water inlet circumferentially for pressurization and then outputting the water axially, which is beneficial to increase the water pressure and improve the cleaning effect. The impeller 23 is a centrifugal impeller, with an inlet corresponding to the water inlet 201 at the bottom and an outlet corresponding to the guide vane 222 at the side.

[0057] The guide vane structure 22 of this embodiment includes a cover plate 221 and a guide plate 222. The cover plate 221 is transversely arranged in the middle of the pump housing 21 and divides the inner cavity of the pump housing 21 into relatively independent upper cavity 211 and lower cavity 212. The water outlet 22 is connected to the upper cavity 211. The guide plates 222 are multiple and vertically arranged on the lower surface of the cover plate 221. The multiple guide plates 222 cover the circumferential area of ​​the cover plate 221 and are arranged at intervals along the circumference. The guide plates 222 extend spirally inward from the edge of the cover plate 221 against the direction of the water flow. A guide channel 223 is constrained between two adjacent guide plates 222. The portion of the cover plate 221 corresponding to the top of the guide plate 222 is at least partially missing to form a gap 224 for connecting the guide channel 223 with the upper cavity 211. The guide vane structure 22 is used to guide the axial inlet water to pressurize it through the circumferential direction and then output it axially to meet the water pressure requirements.

[0058] The outer end of the guide vane 222 is arranged close to the inner circumferential wall of the pump casing 21, and the outer end is arranged close to the edge of the impeller 23. Among the two adjacent guide vanes 222, the outer end portion of the first guide vane 222 and the inner end portion of the second guide vane 222 are arranged in an interlaced manner to enclose the guide channel 223. The cover plate 221 is missing in the range from the outer end of the first guide vane 222 to the outer end of the second guide vane 222 to form a gap 224. With such a structure, the gap 224 is reasonably connected with the water outlet end of the guide channel 223 to reduce energy loss. The upper surface of the cover plate 221 is provided with a converging blade 225 that spirally extends from the edge to the middle and is used to gather the water transported through the gap 224 to the water outlet 202. This structure can rectify and guide the water flow entering the upper cavity 211, avoid energy loss caused by water flow turbulence, and increase water pressure and head.

[0059] This embodiment also includes a cover 4 and an elastic member 5. The cover 4 is disposed in the upper cavity 211 of the pump housing 21 so as to be movable up and down, and is used to open or close the water outlet 202. The elastic member 5 is disposed on the guide vane structure 22 so as to keep the cover 4 always in a tendency to move upward. The bottom of the vegetable basket 3 is provided with a support leg 39 which can pass through the water outlet 202 and press the cover 4 to move downward. The support leg 39 is used to press the cover 4 under the gravity of the vegetable basket 3 to open the water outlet 202, and at the same time connect the water inlet 31 of the vegetable basket 3 with the water outlet 202 of the pump housing 21.

[0060] When the vegetable basket 3 is placed in the sink body 1, the water inlet 31 is aligned with the water outlet 202, the lower end of the support leg 39 abuts against the upper surface of the cover 4 to open the water outlet 202, and the elastic member 5 is a spring and is in a compressed state. The support leg 39 includes three support ribs 391 extending downward from the edge of the water inlet 31 and arranged at intervals in the circumferential direction of the water inlet 31. The support leg 39 formed by the support ribs 391 can also guide the water flow upward to reduce the energy loss of the water flow because it is located in the upper cavity 211 and is larger at the bottom and smaller at the top.

[0061] The guide vane structure 22 is disposed in the upper cavity 211 and spirally extends from the edge of the upper cavity 211 to the middle, and is used to gather the water flow conveyed from the lower cavity 212 to the water outlet 202. The inner ends of the converging vanes 225 together enclose a receiving cavity 226 for accommodating the cover 4 and the elastic member 5. The cover 4 is movably disposed in the receiving cavity 226, and the elastic member 5 is elastically compressed under the cover 4. The converging vanes 225 gather the water flow from the edge of the upper cavity 211 to the middle, and then guide the water upward through the support legs 39 to reduce energy loss.

[0062] The vegetable basket 3 of the present invention has its own flow channel, and a plurality of water spray holes 32 are arranged on the inner wall of the vegetable basket 3. The water column can be directly sprayed onto the fruits and vegetables in the vegetable basket through the built-in flow channel of the vegetable basket 3. Without the obstruction of the bottom wall of the vegetable basket, the water column can cover the interior of the vegetable basket over a large area and with high pressure, thereby eliminating dead corners in cleaning and improving the cleaning effect. The vegetable basket 3 of this embodiment can be directly placed in the water tank body 1 and connected to the water pump mechanism 2 to realize water return, and can be used as a fruit and vegetable washing machine. After the vegetable basket 3 is taken out, it automatically switches to a common water tank for use, which is easy to operate and use.
