Description

Technical Field

[0001] This utility model relates to an installation structure for a filter screen of a cleaning machine. Background Technology

[0002] Currently available cleaning machines are designed for cleaning small items such as tableware, baby bottles, and their accessories. These machines typically have a filter at the bottom of the inner tank to trap food debris in the water. Most cleaning machines use two filters: one for collecting larger debris and the other primarily for filtering the water. After each use, users need to disassemble both filters separately, which is inconvenient and time-consuming.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide an installation structure for a cleaning machine filter screen, which simplifies the installation of the filter screen and makes it more convenient for users.

[0005] To achieve the above objectives, this utility model provides an installation structure for a cleaning machine filter screen, comprising a cleaning machine body, a plate-shaped filter screen, and a cage-shaped filter screen. The cleaning machine body has a cleaning inner tank with a water collection cavity at the bottom. The plate-shaped filter screen covers the opening of the water collection cavity and has an installation port. The horizontal height of the outer edge of the plate-shaped filter screen gradually decreases from the installation port. The cage-shaped filter screen has an upper opening structure, is placed on the installation port and presses against the plate-shaped filter screen, and is snapped and fixed to the water collection cavity. The horizontal height of the upper opening of the cage-shaped filter screen is lower than the upper surface of the plate-shaped filter screen.

[0006] In one or more embodiments, the wall of the water collection cavity is provided with a retaining rib, and the outer side of the cage-like filter screen is provided with a locking position that engages with the retaining rib. The cage-like filter screen can be rotated to engage the locking position with the retaining rib, or to separate the locking position from the retaining rib.

[0007] In one or more embodiments, the plate-shaped filter screen has an annular recessed step at the mounting opening, and the cage-shaped filter screen has an annular pressing flange pressed onto the annular recessed step.

[0008] In one or more embodiments, the water collection cavity has a mounting recess along its opening, a plate-shaped filter screen is placed on the mounting recess, and the bottom surface of the mounting recess is inclined.

[0009] In one or more embodiments, the cage-like filter screen is provided with a plurality of upwardly extending columns, forming a slag passage zone between the columns, and the upper end of the columns is connected to a ring frame.

[0010] In one or more embodiments, the outer surface of the ring frame has a plurality of recessed areas distributed circumferentially.

[0011] Compared with the prior art, the present invention simplifies the installation of plate-shaped and cage-shaped filters. The plate-shaped filter can be placed directly in the designated position and fixed by the cage-shaped filter being snapped into the water collection cavity, which is convenient for users to disassemble and assemble.

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] See appendix Figure 1-4 This application provides an installation structure for a cleaning machine filter screen, which includes a cleaning machine body 1, a plate-shaped filter screen 2, and a cage-shaped filter screen 3. The cleaning machine body 1 has a cleaning inner tank 4, and a water collection cavity 5 is provided on the bottom of the cleaning inner tank 4. The plate-shaped filter screen 2 covers the opening of the water collection cavity 5 and has an installation port 6. The horizontal height from the outer edge of the plate-shaped filter screen 2 to the installation port 6 gradually decreases, making the plate-shaped filter screen a concave arc shape, so as to guide the residue and water flow to the installation port 6. The cage-shaped filter screen 3 has an upper opening structure. The cage-shaped filter screen 3 is placed on the installation port 6 and presses the plate-shaped filter screen 2. The cage-shaped filter screen 3 is snapped and fixed to the water collection cavity 5. After the cage-shaped filter screen is snapped to the water collection cavity 5, the plate-shaped filter screen is pressed at the same time, eliminating the need for fixing the plate-shaped filter screen. The horizontal height of the upper opening of the cage-shaped filter screen 3 is lower than the upper surface of the plate-shaped filter screen 2, so that the residue on the plate-shaped filter screen flows into the cage-shaped filter screen 3 and is collected by the cage-shaped filter screen.

[0018] The water collection cavity 5 has a retaining rib 7 on its cavity wall, and the outer side of the cage-shaped filter screen 3 has a locking position 8 that engages with the retaining rib 7. The cage-shaped filter screen 3 can be rotated to engage the locking position 8 with the retaining rib 7, or to separate the locking position 8 from the retaining rib 7. With the above structure, the user can install or disassemble the cage-shaped filter screen by rotating the cage-shaped filter screen 3, which is very convenient to operate.

[0019] The plate-shaped filter screen 2 is provided with an annular recessed step 9 at the mounting port 6, and the cage-shaped filter screen 3 is provided with an annular pressing edge 10 pressed on the annular recessed step 9. With the cooperation of the annular pressing edge 10 and the annular recessed step 9, the sealing performance at the connection between the cage-shaped filter screen 3 and the plate-shaped filter screen 2 can be improved, and the connection tightness between the two can be improved, thereby improving the fixing effect on the plate-shaped filter screen 2.

[0020] The water collection cavity 5 has an installation recess 11 along its opening. The plate-shaped filter screen 2 is placed in the installation recess 11. The installation recess plays a role in positioning and installing the plate-shaped filter screen. The bottom surface of the installation recess 11 is inclined to guide water.

[0021] The cage-shaped filter screen 3 is provided with several upwardly extending columns 12, and a slag passage zone 13 is formed between the columns. The residue on the plate-shaped filter screen 2 enters the cage-shaped filter screen 3 through the slag passage zone 13. The upper end of the column 12 is connected to a ring frame 14. The ring frame allows the user to hold and rotate the cage-shaped filter screen. To avoid slipping and to facilitate the user's rotation of the cage-shaped filter screen, multiple recessed areas 15 are distributed circumferentially on the outer side of the ring frame 14.

[0022] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
