Description

Technical Field

[0001] This invention relates to the field of kitchen cleaning equipment, specifically a cleaning machine. Background Technology

[0002] A cleaning machine is a device that sprays cold or hot water onto dishes and items to remove dirt adhering to them. A typical cleaning machine mainly includes a body forming a cleaning chamber, a control panel, a water pump for spraying washing water, a rotating spray arm, a slag basket assembly, a drainage assembly, and a heater for generating hot water. Existing cleaning machines circulate and filter the cleaning water by covering the tank with a filter plate. The filter plate has mounting holes for installing the slag basket assembly, where residue washed off the items is collected.

[0003] For example, the Chinese utility model patent disclosed in patent number CN202121480853.1 (publication number CN215502871U) entitled "Filter Plate for Dishwasher and Dishwasher" includes a cabinet with a recessed water return area at the bottom. The filter plate covers the top of the water return area. The bottom of the cabinet is provided with a water distribution chamber that communicates with the water return area. The water supply pipe extends longitudinally close to the inner wall of the cabinet. The lower end of the water supply pipe passes through the assembly port on the second filter plate and connects to the water outlet at the upper end of the water distribution chamber.

[0004] Because the water in the dishwasher's cabinet contains food residue from the initial washing cycle, even with the filter basket, small particles may still enter the return water area, causing the walls of the return water area to become dirty and require cleaning. This necessitates removing the filter plate, which is quite troublesome. Even after disassembly and cleaning, blind spots for cleaning and drying will still exist. Over time, this area will accumulate dirt, food residue, and other grime, causing secondary contamination of dishes, fruits, and vegetables, thus affecting the dishwasher's cleaning, sterilization, and preservation effects. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a cleaning machine that can use the water flow channel in the drain plate to rinse the drain area, in view of the current state of the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a cleaning machine with a spray nozzle that can deflect and rinse, in view of the current state of the prior art.

[0007] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a cleaning machine, comprising:

[0008] The box has a hollow interior forming a cleaning chamber, and the bottom of the box has a downward-recessed drainage area;

[0009] A draining board is used to cover the open area of ​​the draining zone.

[0010] A water pumping mechanism is provided inside the cleaning chamber, and it has a first water outlet for pumping cleaning water from the draining area to the cleaning chamber.

[0011] The pumping mechanism also has a second water outlet end, and the drain plate has a water flow channel for rinsing the drain area. Along the direction of fluid flow, the water flow channel is arranged downstream of the pumping mechanism, with its inlet end in fluid communication with the second water outlet end of the pumping mechanism and its outlet end located within the drain area.

[0012] To avoid obstructing the original slag-separating function of the drain plate when the water flow channel washes the draining area, preferably, the drain plate includes a first plate body and a second plate body, with the water flow channel disposed on one of the first and second plate bodies, and the outlet end of the water flow channel having spray holes for rinsing the draining area. This two-plate design allows one plate body to perform its original slag-separating function, while the other can house the aforementioned water flow channel, achieving effective diversion of pumped cleaning water.

[0013] Specifically, both the first plate and the second plate are disc-shaped, arranged vertically and at least partially overlapping.

[0014] To ensure that the spray holes in the water flow channel can rinse the drainage area, preferably, a guide pipe is provided at the bottom of the second plate along the circumferential edge. The guide pipe is hollow inside to form the water flow channel, and the spray holes are formed on the guide pipe.

[0015] To ensure uniform rinsing of the drainage area, specifically, there are at least two spray holes, and each spray hole is arranged at intervals along the length of the guide pipe.

[0016] To ensure the rinsing water flow effectively collects residue, preferably, each of the nozzles is arranged at an angle towards the center of the first plate, so that the sprayed water flow is generally converged in the circumferential direction of the drain plate. This arrangement of multiple nozzles, through their converged posture, allows the impact force of the spray to gather the residue as it enters the draining area, facilitating the collection of food waste.

[0017] To ensure that water is delivered into the water flow channel, preferably, the bottom of the second plate is also provided with a guide pipe, which extends radially along the first plate and has a hollow interior forming an ejector channel. Along the direction of fluid flow, the ejector channel is arranged upstream of the water flow channel, and the direction of fluid flow inside it intersects with the direction of fluid flow inside the water flow channel.

[0018] Specifically, the second plate has at least two nozzles extending radially along the guide tube, the outlet of each nozzle being the spray hole, and the nozzles are spaced apart along the length of the guide tube.

[0019] To further address the second technical problem mentioned above, the technical solution adopted by this invention is as follows: the cleaning machine further includes a first driver, the power output end of which is connected to one of the first plate and the second plate, causing the first plate and the second plate to rotate relative to each other, thereby moving each of the nozzles in the deflection direction of the second plate. This structural design, where the first driver drives the first or second plate to move and deflects the nozzles, allows the water flow channel to rinse the draining area with the help of the nozzles, while simultaneously achieving directional rotation of the water flow within the draining area through the deflection of the nozzles. This also helps to collect food residue within the draining area; furthermore, the directional deflection of the water flow changes the position of the nozzles, ensuring effective rinsing of the draining area and avoiding any blind spots.

[0020] The drain plate can have different structural forms. In order to achieve the deflection of the nozzle, preferably, the periphery of the first plate is bent downward to form a rolled edge, and a gap is left between the rolled edge and the first plate to form a limiting groove. The second plate is located within the range defined by the rolled edge, and the guide tube on its outer edge is constrained in the limiting groove. The rolled edge has at least two adjustment holes along the wall thickness direction for the corresponding nozzle to extend out. Furthermore, the guide tube can move relative to the limiting groove when the first plate and the second plate rotate relative to each other, thereby causing the nozzle to deflect to one side of the adjustment hole.

[0021] Specifically, all the nozzles deflect in the same direction, thus presenting the same rotation direction relative to the rolled edge as a whole. The deflection direction can be either clockwise or counterclockwise relative to the guide tube.

[0022] Preferably, the first driver is arranged outside the housing, and its output shaft extends into the housing. The cleaning chamber is provided with a swing arm in the area adjacent to the drain plate. The first end of the swing arm is connected to the output shaft of the first driver, and the second end is connected to the second plate.

[0023] Specifically, the first driver is located below the housing and extends upward along the output axis, the swing arm is arranged above the drain plate, and the first plate has a vertically penetrating limiting opening at the edge adjacent to the first driver.

[0024] To further ensure the filtration of residue, preferably, the first plate and the second plate are respectively provided with a first filter hole and a second filter hole for water flow. When the first plate and the second plate rotate relative to each other, the first filter hole and the second filter hole can be in a first working state of mutual alignment or a second working state of mutual misalignment, thereby correspondingly increasing or decreasing the water flow of the drain plate.

[0025] To prevent residue from clogging the first and second filter holes, preferably, the bottom plate and side plate of the drainage area have an arc-shaped transition area, and the nozzle of the spray head is arranged toward the arc-shaped transition area or the bottom plate of the drainage area, thereby forming a reflected water flow in the drainage area for backwashing the first and second filter holes.

[0026] To achieve the rinsing of tableware, preferably, a spray arm is provided in the cleaning chamber, and the water pumping mechanism is located at the bottom of the box and below the draining area. The water pumping mechanism has a water pumping element and a second driver. The power output end of the second driver is connected to the water pumping element to drive the water pumping element to move relative to each other, thereby pumping the cleaning water to the spray arm.

[0027] Specifically, the cleaning chamber also has a slag collection basket, which is fixed on the first plate and located in the draining area, and the second plate has a clearance opening at the corresponding position for the slag collection basket to pass through.

[0028] Compared with the prior art, the advantages of the present invention are as follows: In this cleaning machine, by setting a water flow channel on the drain plate and arranging the second water outlet of the water flow channel in the drain area, the water output by the pumping mechanism can not only achieve the normal cleaning function through the first water outlet, but also be guided into the water flow channel of the drain plate and output through the water flow channel to achieve rinsing of the drain area. Compared with the existing cleaning machines, this method of adding a water flow channel on the drain plate eliminates the need for a separate rinsing mechanism. It can automatically rinse the drain area by simply diverting the cleaning water during pumping, so as to wash away the residue and dirt in the instant they remain, and prevent them from accumulating in the drain area.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] like Figures 1 to 8 The image shows a preferred embodiment of the present invention. In this embodiment, the washing machine includes a housing 1, a drain plate 2, and a water pumping mechanism 3. The housing 1 is hollow inside to form a washing chamber 10, and the bottom of the housing 1 has a downwardly recessed draining area 1a. To separate food residue, the drain plate 2 covers the opening of the draining area 1a. The washing machine in this embodiment can be different models of washing equipment; a dishwasher is used as an example here, and tableware is placed inside the washing chamber 10 of the washing machine.

[0039] To rinse the tableware inside the washing chamber 10, a water outlet mechanism is typically installed inside the washing chamber 10. In this embodiment, a spray arm 31 is installed inside the washing chamber 10. A water pumping mechanism 3 is located at the bottom of the housing 1 and below the draining area 1a. This water pumping mechanism 3 has a water pumping element 32 and a second driver 33. The power output end of the second driver 33 is connected to the water pumping element 32 to drive the water pumping element 32 to move relative to each other, thereby pumping the washing water to the spray arm 31. The above-mentioned water pumping mechanism 3 is a conventional structure and will not be described in detail. The water path can be found in [reference needed]. Figure 8 .

[0040] In this embodiment, the water pumping mechanism 3 is located inside the cleaning chamber 10, and it has a cleaning water inlet 3c and a first water outlet 3a for pumping the cleaning water in the draining area 1a to the cleaning chamber 10. The cleaning water output from the first water outlet 3a can be delivered to the spray arm 31, thereby rinsing the tableware. In order to rinse the draining area 1a, the drain plate 2 also has a water flow channel 20 for rinsing the draining area 1a. In addition to the first water outlet 3a, the water pumping mechanism 3 also has a second water outlet 3b. Along the direction of fluid flow, the water flow channel 20 is arranged downstream of the water pumping mechanism 3, and its inlet end is in fluid communication with the second water outlet 3b of the water pumping mechanism 3, and its outlet end is located in the draining area 1a. Specifically, the aforementioned drain plate 2 includes a first plate body 21 and a second plate body 22. A water flow channel 20 is disposed on one of the first plate body 21 and the second plate body 22, and the water outlet end of the water flow channel 20 has a spray hole 230 for rinsing the drain area 1a. In this embodiment, both the first plate body 21 and the second plate body 22 are disc-shaped, arranged vertically and at least partially overlapping. The water flow channel 20 and the spray hole 230 can have different configurations. The bottom of the aforementioned second plate body 22 has a guide pipe 23 at its circumferential edge. The guide pipe 23 is hollow inside to form the water flow channel 20, and the spray hole 230 is formed on the guide pipe 23.

[0041] In this embodiment, there are at least two nozzles 230, and each nozzle 230 is arranged at intervals along the length of the guide pipe 23. Furthermore, each nozzle 230 is arranged inclined towards the center of the first plate 21 radially, so that the sprayed water flow is generally converged in the circumferential direction of the drain plate 2. A guide pipe 24 is also provided at the bottom of the second plate 22. This guide pipe 24 extends radially along the first plate 21 and has a hollow interior forming an ejector channel. Along the fluid flow direction, the ejector channel is arranged upstream of the water flow channel 20, and the flow direction of the fluid inside it intersects with the flow direction of the fluid in the water flow channel 20. To achieve the spraying of the nozzles 230, the guide pipe 23 of the second plate 22 has at least two nozzles 231 extending radially along the guide pipe. The outlet of each nozzle 231 is the nozzle 230, and each nozzle 231 is arranged at intervals along the length of the guide pipe 23.

[0042] In addition to conventional spray rinsing, the above-mentioned nozzle 231 can also achieve deflection spray. The cleaning machine in this embodiment also includes a first driver 25, the power output end of which is driven connected to one of the first plate 21 and the second plate 22, so that the first plate 21 and the second plate 22 rotate relative to each other, so that each nozzle 231 moves in the deflection direction of the second plate 22. Specifically, the periphery of the first plate 21 is bent downwards to form a rolled edge 211. A gap is left between the rolled edge 211 and the first plate 21 to form a limiting groove 212. The second plate 22 is located within the area defined by the rolled edge 211, and the guide tube 23 on its outer edge is constrained within the limiting groove 212. The rolled edge 211 has at least two adjustment holes 213 along the wall thickness direction for the corresponding nozzles 231 to extend out. Furthermore, the guide tube 23 can move relative to the limiting groove 212 when the first plate 21 and the second plate 22 rotate relative to each other, thereby causing the nozzles 231 to deflect towards one side of the adjustment hole 213. Moreover, the deflection direction of each nozzle 231 is the same, so that they present the same rotation direction relative to the rolled edge 211 as a whole. The aforementioned first driver 25 is arranged outside the housing 1, with its output shaft extending into the housing 1. The cleaning chamber 10 has a swing arm 26 in the area adjacent to the drain plate 2. The first end of the swing arm 26 is connected to the output shaft of the first driver 25, and the second end is connected to the second plate 22. Specifically, the first driver 25 is located below the housing 1 and its output shaft extends upward. The swing arm 26 is arranged above the drain plate 2, and the first plate 21 has a vertically penetrating limiting opening 214 at the edge adjacent to the first driver 25.

[0043] To further ensure the filtration of food residue, in this embodiment, the first plate 21 and the second plate 22 are respectively provided with a first filter hole 20a and a second filter hole 20b for water flow. When the first plate 21 and the second plate 22 rotate relative to each other, the first filter hole 20a and the second filter hole 20b can be in a first working state of mutual alignment or a second working state of mutual misalignment, thereby correspondingly increasing or decreasing the water flow of the drain plate 2. Furthermore, there is an arc-shaped transition area between the bottom plate and the side plate of the drain area 1a. The nozzle 230 of the spray head 231 is arranged towards this arc-shaped transition area or the bottom plate of the drain area 1a, thereby forming a reflected water flow in the drain area 1a for backwashing the first filter hole 20a and the second filter hole 20b.

[0044] In addition, the cleaning chamber 10 also has a slag collection basket 34, which is fixed on the first plate 21 and located in the draining area 1a. The second plate 22 has a clearance notch 30 at the corresponding position for the slag collection basket 34 to pass through.

[0045] The term "fluid connectivity" as used in this invention refers to the spatial relationship between two components or parts (hereinafter referred to as the first part and the second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. This third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.

[0046] Furthermore, the specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
