[0020] See also Figures 1 to 4As shown, according to an embodiment of the present invention, there is provided a hanging rod seat, including a hanging rod seat body 1, on which a hanging rod matching hole 11 is constructed, and the hanging rod matching hole 11 is used to form a supporting connection for one end of the hanging rod 100. It can be understood that the other end of the hanging rod 100 forms a supporting connection with a washing tub 300 of a pulsator washing machine, so that the washing tub 300 can be suspended in a frame box 200 of the pulsator washing machine, and the hanging rod seat body 1 is also constructed with a mounting portion for a liquid level sensor 2, and the liquid level sensor 2 is installed at the mounting portion. In this technical solution, a mounting portion for a liquid level sensor is constructed on the hanging rod seat, and the liquid level sensor 2 can be installed in the mounting portion, and there is no need to separately set a corresponding liquid level sensor fastening structure on the frame box of the washing machine, which simplifies the structural design and assembly process of the washing machine, and the structure is more compact.

[0021] The mounting portion can be, for example, a groove that matches the shape of the liquid level sensor 2. The liquid level sensor 2 can be placed in the groove. Of course, it can also be fastened in place with corresponding screws. Preferably, the mounting portion includes a through hole 31, and a plurality of hooks 32 are provided in the circumference of the through hole 31. The plurality of hooks 32 can limit the liquid level sensor 2 at the through hole 31, that is, the through hole 31 forms a preliminary positioning of the liquid level sensor 2, and the setting of the hooks 32 can form a buckle positioning for the liquid level sensor 2, so that the position of the liquid level sensor 2 is more stable and reliable.

[0022] Furthermore, a liquid level pipe groove 33 is constructed on the suspension rod seat body 1 to form a fixed guide for the liquid level pipe 21 of the liquid level sensor 2 to prevent the liquid level pipe 21 from contacting or interfering with moving parts during the operation of the washing machine.

[0023] In some embodiments, the hole wall of the hanger mating hole 11 has an open groove 12, and the open groove 12 extends along the hole depth direction of the hanger mating hole 11 and penetrates the inner and outer sides of the hole wall along the radial direction of the hanger mating hole 11, that is, the hole wall of the hanger mating hole 11 has a notch, through which the connecting rod portion of the hanger 100 can enter the hanger mating hole 11, thereby, the hanger 100 can be manufactured in an integral molding manner and can meet the requirements of its smooth assembly with the hanger mating hole 11. In the prior art, the two ends of the hanger 100 respectively have bulging portions matching the hanger mating hole 11 and the hanger support seat 303 of the washing bucket 300. When the hanger mating hole 11 does not have the open groove 12, the bulging portion must be detachably connected to the rod, which on the one hand leads to the complexity of assembly, and on the other hand there is a hidden danger of insufficient connection reliability. The aforementioned scheme of the present application can make the hanger 100 integrally molded.

[0024] The connection method between the boom seat body 1 and the frame box 200 can be various. The best one is that the boom seat body 1 is also constructed with a plurality of connection holes 13. The boom seat body 1 is connected to the frame box 200 through a plurality of bolt connectors. This connection method has a higher connection strength.

[0025] According to an embodiment of the present invention, a pulsator washing machine is also provided, comprising a frame box 200, a washing tub 300 and the above-mentioned hanging rod seat, wherein the hanging rod seat is connected to the top of the frame box 200, the hanging rod seat is suspendedly connected with the washing tub 300 through the hanging rod 100, and the liquid level sensor 2 is connected to the hanging rod seat. Further, a liquid level cavity 301 is provided on the outer peripheral wall of the washing tub 300, the liquid level cavity 301 is communicated with the inner cavity of the washing tub 300, and the liquid level sensor 2 can detect the liquid level in the liquid level cavity 301, and the liquid level cavity 301 and the inner cavity of the washing tub 300 form a communicating vessel principle, so that the liquid level can be detected without the liquid level sensor 2 contacting the inside of the washing tub 300, thereby preventing damage caused by contact connection.

[0026] As mentioned above, the liquid level sensor 2 has a liquid level tube 21, one end of the liquid level tube 21 is connected to the first detection port 22 of the liquid level sensor 2, and the other end of the liquid level tube 21 is connected to the second detection port 302 of the liquid level cavity 301. At this time, part of the gas is actually sealed in the liquid level tube 21, and this part of the gas is between the liquid level of the liquid level cavity 301 and the first detection port 22. When the liquid level height of the liquid level cavity 301 changes, the air pressure in the liquid level tube 21 will change, and the liquid level sensor 2 can detect the aforementioned air pressure change and then know the actual liquid level in the liquid level cavity 301 and then judge the liquid level in the washing tub 300. This method does not require the liquid level sensor 2 to form direct contact with the liquid, the layout is more flexible, and there is no risk of damage to it caused by the movement of the washing tub 300 during operation.

[0027] It can be understood that a plurality of suspension rod support seats 303 are further provided on the outer peripheral wall of the washing tub 300, and the other end of the suspension rod 100 is supported and connected with the suspension rod support seat 303, and the plurality of suspension rod support seats 303 are evenly spaced along the circumference of the outer peripheral wall of the washing tub 300. The structure of the matching portion between the suspension rod support seat 303 and the end of the suspension rod 100 may be the same as the structure of the suspension rod matching hole 11.

[0028] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
