In other embodiments of the present invention, the water level detecting device can also be used to detect the water level in a drum-type washing machine or other types of washing equipment or water storage equipment.
Fig. 1 is a schematic view illustrating a connection structure between a water level detecting device and an outer tub of a wall-mounted washing machine according to an embodiment of the present invention. Fig. 2 is a schematic view of the overall structure of the water level detecting apparatus of fig. 1. Fig. 3 is an exploded view of the water level detecting apparatus of fig. 2. As shown in fig. 1, 2 and 3, the water level detecting device 100 in the present embodiment includes a drain pump body 10, an air pressure pipe 20 and a water level sensor 30. The inner cavity of the drainage pump body 10 is connected to the accommodating cavity surrounded by the outer tub 200 of the wall-mounted washing machine, the inlet end 21 of the air pressure conduit 20 is connected to the inner cavity of the drainage pump body 10, and the water level sensor 30 is connected to the outlet end 22 of the air pressure conduit 20.
According to the water level detecting apparatus in this embodiment, the inner cavity of the drainage pump body 10 is in communication connection with the accommodating cavity surrounded by the outer tub 200, and the inlet end 21 of the air pressure conduit 20 is in communication connection with the inner cavity of the drainage pump body 10, so that the connection reliability between the air pressure conduit 20 and the accommodating cavity surrounded by the outer tub 200 is effectively improved, the risk of water leakage is reduced, the pressure generated in the air pressure conduit 20 can be accurately measured by the water level sensor 30, and the water level in the accommodating cavity surrounded by the outer tub 200 can be determined by the measured pressure generated in the air pressure conduit 20.
The air pressure conduit 20 in this embodiment is a rubber tube or a silicone tube, so that the position of the water level sensor 30 can be conveniently adjusted. As shown in fig. 1, when the wall-mounted washing machine is in a hanging state, the back plate 300 is vertically placed, and the outer tub 200 is disposed perpendicular to the plate surface of the back plate 300. In order to drain the washing water in the outer tub 200 of the wall-mounted washing machine tub as much as possible, a drain opening (not shown) is provided at the lowest portion of the outer tub 200 in the vertical direction, and the receiving cavity surrounded by the outer tub 200 is in communication with the drain pump body 10 through the drain opening. Since the drain pump body 10 is connected to the outer tub 200, the lowest part of the entire water level is located in the drain pump body 10, and the washing water in the outer tub 200 can flow out through the drain pump body 10.
When the wall-mounted washing machine is in a working state and enters a washing mode, water enters into a containing cavity formed by the outer tub 200 (i.e., an inner cavity of the outer tub 200). Since the water surface of the inner cavity of the outer tub 200 is atmospheric pressure, and the inlet end 21 of the air pressure conduit 20 is connected to the inner cavity of the outer tub 200 through the drain pump body 10, and the outlet end 22 of the air pressure conduit 20 is connected to the water level sensor 30, as the water level in the inner cavity of the outer tub 200 gradually rises, the washing water in the drain pump body 10 further compresses the gas in the air pressure conduit 20, so that the air pressure of the gas in the air pressure conduit 20 also gradually rises, and the air pressure in the air pressure conduit 20 is detected by the water level sensor 30, and the water level position in the inner cavity of the outer tub 200 is determined accordingly.
Specifically, as shown in fig. 4 and 5, the drain pump body 10 of the present embodiment is provided with a water inlet 11 for communicating with a drain outlet of the outer tub 200, and a communication joint 12 for communicating with an inlet end 21 of the air pressure duct 20. In order to compress the gas in the air pressure conduit 20 during the inflow and outflow of the washing water in the drainage pump body 10, in this embodiment, the conductive joint 12 connected to the air pressure conduit 20 is disposed between the water inlet 11 and the water outlet 15 of the drainage pump body 10, so that the washing water can flow into the air pressure conduit 20 through the conductive joint 12 during the inflow and outflow of the drainage pump body 10, and compress the gas in the air pressure conduit 20, thereby increasing the air pressure in the air pressure conduit 20, detecting the air pressure value in the air pressure conduit 20 through the water level sensor 30, and determining the water level position in the outer tub 200. In this embodiment, the pneumatic conduit 20 is connected to the conducting connector 12 through the inlet end 21, and the outlet end 22 of the pneumatic conduit 20 is disposed at a position higher than the inlet end 21, i.e. the water level sensor 30 is disposed at a position higher than the inlet end 21. In order to obtain a more reliable detection result, the water level sensor 30 should be disposed higher than the water outlet, and the water level sensor 30 is generally disposed at the height 2/3 in the vertical direction of the accommodating cavity surrounded by the outer tub 200, so that the air pressure conduit 200 forms a U-shaped conduction structure in the vertical direction.
When the wall-mounted washing machine is in operation, the washing water in the outer tub 200 flows into the inner cavity of the drainage pump body 10 through the water inlet 11 by the action of its own gravity, and the washing water entering the drainage pump body 10 enters the air pressure duct 20 through the communication joint 12, so as to compress the air in the air pressure duct 20, and raise the air pressure in the air pressure duct 20. Since the air pressure in the air pressure guide tube 20 is proportional to the water level in the inner cavity of the outer tub 200, the water level in the outer tub 200 is determined by detecting the air pressure in the air pressure guide tube 20 by the water level sensor 30.
Further, the conduction joint 12 in the present embodiment is provided on the outer side surface of the drain cylinder 10 and is capable of being connected to the air pressure pipe 20 by being inserted into the air pressure pipe 20, and a conduction passage 121 for communicating the drain cylinder 10 and the air pressure pipe 20 is provided inside the conduction joint 12. As shown in fig. 4, the conducting joint 12 is a cylindrical structure, and the outer diameter of the conducting joint 12 is greater than or equal to the inner diameter of the pneumatic conduit 20, so that the conducting joint 12 can be tightly fitted with the pneumatic conduit 20 after being inserted into the pneumatic conduit 20. The conductive joint 12 is internally provided with a conductive passage 121 to introduce the washing water in the drain pump body 10 into the air pressure guide pipe 20 and compress the air in the air pressure guide pipe 20, thereby determining the water level of the washing water in the outer tub 200 by the water level sensor 30.
The connection reliability between the air pressure pipe 20 and the drain pump body 10 is improved by providing the conduction joint 12 on the drain pump body 10 and connecting the air pressure pipe 20 and the drain pump body 10 by using the conduction joint 12. Meanwhile, the washing water in the outer tub 200 enters the drain pump body 10 and then acts on the gas in the air pressure guide duct 20 to compress the gas in the air pressure guide duct 20, so that the pressure of the gas in the air pressure guide duct 20 is detected by the water level sensor 30 and the water level in the outer tub 200 is judged. The water level detecting apparatus 100 of the present embodiment utilizes the drain pump body 10, so that the overall structure is simple, and the washing water in the air pressure conduit 20 can be drained through the drain pump body 10, thereby improving the safety and reliability of the use of the apparatus.
In order to further increase the sealing performance between the conducting joint 12 and the pneumatic conduit 20 and reduce the occurrence of water leakage, a first fastening member (not shown) is further disposed around the outer side surface of the connection portion between the pneumatic conduit 20 and the conducting joint 12, and the first fastening member may be a clamp, a tie or other fastening member. The outer side surface of the air pressure conduit 20 is extruded through the first fastening piece, so that the inner wall surface of the air pressure conduit 20 is tightly attached to the outer side surface of the conduction joint 12, and the air tightness of the connection part of the air pressure conduit 20 and the conduction joint 12 can be effectively improved. Similarly, in order to increase the air tightness of the connection between the air pressure conduit 20 and the water level sensor 30, a second fastening member (not shown) is also provided on the outer side of the connection between the air pressure conduit 20 and the water level sensor 30. The air pressure conduit 20 is tightly attached to the water level sensor 30 through the second fastening piece, so that the air leakage phenomenon at the joint of the air pressure conduit 20 and the water level sensor 30 can be effectively reduced, and the accuracy of the detection result of the water level sensor 30 is improved.
Further, as shown in fig. 5, the drainage pump body 10 of the present embodiment is further provided with a filter assembly mounting opening 13 capable of being connected with the filter assembly in a matching manner.
Since the water after washing may contain solid impurities (such as swarf, ornaments, small keys, etc.), in order to avoid blocking the drain pipe or the drain pump body 10 during draining, the drain pump body 10 is provided with a filter assembly mounting opening 13 which can be connected with the filter assembly in a matching manner. The filter assembly is rotatably connected to the filter assembly mounting hole 13 of the drain pump body 10, and is separated from the drain pump body 10 by rotating the filter assembly after the filter assembly filters impurities in the washing water and the draining is completed. The filter assembly is cleaned and then rotated to connect the filter assembly to the drain pump body 10 for further use. In this embodiment, the inner cavity of the filter assembly mounting opening 13 and the inner cavity of the water inlet 11 are coaxially arranged, so that the filter screen on the filter assembly can contact with the washing water in the largest area, and the filtering efficiency of the filter assembly is improved. Meanwhile, the filter assembly mounting port 13 also has a drainage function. When the drain pump body 10 does not have a water outlet, the washing water can be discharged through the filter unit mounting port 13 by detaching the filter unit from the drain pump body 10.
Further, as shown in fig. 5, the drainage pump body 10 of the present embodiment is further provided with a drainage motor mounting opening 14 capable of being connected with a drainage motor in a matching manner.
In this embodiment, the inner cavity of the drain motor mounting port 14 is coaxially disposed with the conduction passage 121. The drain pump body 10 is connected to a drain motor by providing a drain motor mounting port 14, and the washing water in the outer tub 200 is discharged by the drain motor. Correspondingly, the drainage pump body 10 in this embodiment is further provided with a water outlet 15 capable of being connected with a drainage pipe in a communication manner.
The present invention also provides a wall-mounted washing machine having the water level detecting device 100 in the above embodiment, wherein the outer tub 200 of the wall-mounted washing machine is provided with a water outlet, and the accommodating cavity surrounded by the outer tub 200 can be connected to the drainage pump 10 through the water outlet.
By using the wall-mounted washing machine in this embodiment, the inner cavity of the drainage pump body 10 is in communication connection with the accommodating cavity surrounded by the outer tub 200, and the inlet end 21 of the air pressure conduit 20 is in communication connection with the inner cavity of the drainage pump body 10, so that the connection reliability between the air pressure conduit 20 and the accommodating cavity surrounded by the outer tub 200 is effectively improved, the risk of water leakage is reduced, the pressure generated in the air pressure conduit 20 can be accurately measured by the water level sensor 30, and the water level in the accommodating cavity surrounded by the outer tub 200 can be judged by the measured pressure generated in the air pressure conduit 20.
