Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to an installation structure for a water level and pressure sensor for a laundry and shoe washing machine. Background Technology

[0002] Currently, in the washing machine industry, water level sensors are generally installed. The water level sensor transmits the detected water level signal to the control terminal through a signal line. The control terminal controls the opening and closing of the water inlet valve based on the received signal.

[0003] In the prior art, patent CN212560805U, entitled "A Washing Machine Water Level Sensor," discloses a washing machine water level sensor including a housing and a detection area connected to the washing tub. An air pipe is connected to the detection area, and the air pipe is connected to a sensor air chamber located above the washing tub. The air pipe extends towards the bottom of the washing tub and then towards the sensor air chamber. By placing the air pipe within the detection area and extending it downwards and then upwards to the sensor air chamber, the pressure changes detected by the sensor air chamber are all pressure changes caused by the addition of water, thus improving the detection accuracy of the water level sensor. The addition of a certain amount of water generates a certain amount of water pressure, which causes a certain amount of air in the detection area to enter the air pipe, generating a certain amount of air pressure. This pressure change is then detected by the sensor air chamber and fed back to the controller with a corresponding signal.

[0004] In the existing technology, these air chambers that collect pressure changes are usually integrally injection molded on the side wall of the cleaning cylinder. This not only makes the mold complex and the manufacturing cost high, but also makes the injection molding process prone to defects and low yield because the connecting hole of the air chamber to the air pipe protrudes from the outside of the cleaning cylinder and the hole diameter is small. Furthermore, during the handling process, the protruding structure is easily damaged by collision, causing the entire cylinder to be scrapped, resulting in large losses per unit and high maintenance costs. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing an installation structure for a water level and pressure sensor in a washing machine or shoe washing machine that is simple in structure, easy to replace, and has low maintenance costs.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an installation structure for a water level and pressure sensor in a washing machine and shoe washing machine, comprising a washing cylinder, a drainage mechanism at the bottom of the washing cylinder, and a detection structure connected to the sensor via an air pipe on the drainage mechanism. By separating the detection structure and connecting it as a separate structure to the drainage mechanism, not only can the mold opening cost be reduced, but the injection molding efficiency and yield rate are also high, and the loss per unit is small.

[0007] In the above technical solution, the detection structure includes a shell structure with interconnected horizontal and vertical cavities. The vertical cavity mainly functions as an air chamber. The change in water level in the horizontal cavity compresses the gas in the vertical cavity to achieve a change in air pressure, thereby transmitting the water pressure information to the sensor.

[0008] In the above technical solution, one of the working ends of the horizontal cavity is open and forms a drainage mechanism connection part.

[0009] In the above technical solution, a tracheal connection part is provided along the cavity wall of the vertical cavity to connect the vertical cavity with the outside, for connecting the tracheal tube.

[0010] In the above technical solution, the drainage mechanism includes a drainage seat, on which an inlet and an outlet are provided. A detection structure connection part is provided on the side wall of the chamber between the inlet and the outlet. The drainage mechanism connection part is connected to the detection structure connection part to realize the connection between the drainage mechanism and the detection structure, so that the water in the cleaning cylinder enters the horizontal chamber. Then, the change in water level in the horizontal chamber squeezes the gas in the vertical chamber to realize the change in air pressure, and then transmits the water pressure status to the sensor.

[0011] In the above technical solution, an air pipe routing structure is reserved on the outer wall of the cleaning cylinder, and the air pipe is arranged along the outer wall of the cleaning cylinder through the air pipe routing structure.

[0012] In the above technical solution, the air tube routing structure is a concave structure with an arc-shaped bottom, so that the air tube is not affected by the compression of other installation structures and the detection effect is not affected, while making the overall cylinder structure more consistent.

[0013] In the above technical solution, one working end of the air pipe extends to the bottom of the cleaning cylinder and is connected to the detection structure through the air pipe connection part, and the other working end of the air pipe extends to the top of the cleaning cylinder and is connected to the sensor.

[0014] In the above technical solution, a reserved channel is provided at the eaves of the cleaning cylinder, and the air pipe passes through the reserved channel to connect with the sensor, which is beneficial for the installation of the air pipe.

[0015] Compared with the prior art, the present invention has the following advantages: by separating the air chamber and connecting it to the drainage mechanism as a separate unit, not only can the cost of the mold be reduced, but the yield rate is also high; the air chamber is separated from the cylinder, which can reduce the risk of water leakage from the cylinder; if the air chamber is damaged, only the detection structure needs to be replaced, without replacing the entire cylinder at the same time, thereby reducing maintenance costs.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0023] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0024] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0025] See Figures 1 to 4An installation structure for a water level and pressure sensor in a washing machine and shoe washing machine includes a washing drum 1, a drainage mechanism 2 at the bottom of the washing drum 1, a sensor 4 at the top of the washing drum 1, an air pipe routing structure 11 reserved on the outer wall of the washing drum 1, and a reserved channel 12 at the eaves of the washing drum 1, which allows the air pipe 3 to be routed along the outer wall of the washing drum 1 through the air pipe routing structure 11, thereby effectively connecting with the sensor 4 and the detection structure 5.

[0026] The detection structure 5 can detect the change in water pressure by transmitting the change in air pressure to the sensor 4 through the air pipe 3, and then output a command to the drainage mechanism 2.

[0027] The detection structure 5 includes a shell structure with a horizontal cavity 51 and a vertical cavity 52 that are interconnected. The vertical cavity 52 mainly functions as an air chamber, and the air pressure changes by the water level change in the horizontal cavity 51 compressing the gas in the vertical cavity 52.

[0028] The horizontal cavity 51 and the vertical cavity 52 are an integral structure. The non-direct connection ends of the horizontal cavity 51 and the vertical cavity 52 are both open structures. One of the working ends of the horizontal cavity 51 is open and forms a drainage mechanism connection part 511. The open end of the vertical cavity 52 is sealed by a plug 53. A tracheal connection part 521 is provided on the cavity wall of the vertical cavity 52 to connect the vertical cavity 52 with the outside.

[0029] Of course, this arrangement is mainly for the convenience of mold making and to reduce manufacturing costs. Alternatively, both the horizontal cavity 51 and the vertical cavity 52 can be closed structures, with a drainage mechanism connection part 511 connected to the outside at one of the working ends of the horizontal cavity 51. In this way, the vertical cavity 52 does not need to be sealed by a plug.

[0030] The drainage mechanism 2 includes a drainage seat with an inlet 21 and an outlet 22. The inlet 21 is connected to the cleaning cylinder 1, and the outlet 22 is connected to a drain pipe 24. A detection structure connection part 23 is provided on the side wall of the chamber between the inlet 21 and the outlet 22. Of course, a drainage control structure is also provided at this location, including a control component that enables the drain valve to open or close the drainage channel. In the non-working state, the drain valve closes the drainage channel, and water flows in through the horizontal cavity 51. The water pressure is then transmitted to the sensor 4 via the air pipe 3, and the sensor 4 controls the control component to operate the drain valve.

[0031] The size and structure of the detection structure connection part 23 match the size and structure of the drainage mechanism connection part 511, which can ensure an effective airtight connection between the drainage mechanism 2 and the detection structure 5.

[0032] An air pipe routing structure 11 is pre-installed on the outer wall of the cleaning cylinder 1. The air pipe routing structure 11 is a concave structure with an arc-shaped bottom. The air pipe 3 is installed along the outer wall of the cleaning cylinder 1 through the air pipe routing structure 11. This ensures that the air pipe is not affected by the compression of other installation structures, thus improving the overall consistency of the cylinder structure. A reserved channel 12 is provided at the eaves of the cleaning cylinder 1. One working end of the air pipe 3 extends to the bottom of the cleaning cylinder 1 and is connected to the detection structure 5 through the air pipe connector 521. The other working end of the air pipe 3 extends to the top of the cleaning cylinder 1, passes through the reserved channel 12, and is connected to the sensor 4.

[0033] By setting the detection structure 5 as an independent mechanism and forming a structure with an air chamber inside, the sensor 4 and the detection structure 5 are effectively connected through the air pipe wiring structure 11 via the air pipe 3. The change in air pressure can be detected and the change in water pressure can be transmitted to the sensor 4, thereby issuing a command output to the drainage mechanism 2.

[0034] When the detection structure is damaged, only the detection structure needs to be replaced, which avoids the drawback of high maintenance costs caused by integrating the air chamber and the cleaning cylinder into one unit in the existing technology. In addition, the mold opening is simple, the yield rate is high, and the service life of the cleaning cylinder is improved, which gives it good market competitiveness.

[0035] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
