Detailed Description
The present invention is illustrated by the following examples, but the present invention is not limited to these examples. To the embodiment of the present invention, modify or replace some technical features, without departing from the spirit of the present invention, it should be covered in the technical solution scope of the present invention.
The first embodiment is as follows: as shown in FIG. 2, a water level and air pressure conduction structure applied to a dishwasher comprises a washing chamber 1, a water cup 2, an air chamber 3, a pressure switch 4 and a connecting pipe 5, wherein the water cup 2 is arranged at the bottom of the washing chamber 1 and has a water collecting function. The air chamber 3 is arranged beside the water cup 2, the air chamber 3 is communicated with the bottom of the water cup 2, the pressure switch 4 is communicated with the air chamber 3 through the connecting pipe 5, and a certain amount of air is sealed in the air chamber 3 after water enters. An air pressure buffer member is provided in the air chamber 3 or the connection pipe 5, and an air pressure change generated by a water level change in the washing chamber 1 is transmitted through the air pressure buffer member to reach the pressure switch 4.
In this embodiment, the air pressure buffering member is made of sponge 6, and the sponge 6 is disposed at the middle position in the air chamber 3 to form a sponge layer, so that the air chamber 3 is divided into an upper air chamber 30 and a lower air chamber 31, and the air chamber 3 is divided into three parts by the sponge layer. The pressure switch 4 is connected to the upper chamber 30 through the connection pipe 5, and the pressure switch 4 senses the air pressure in the chamber 3 varying with the water level of the washing chamber 1.
Further, a vent hole 32 is formed in one side of the upper air chamber 30, and the vent hole 32 communicates the upper air chamber 30 with the connecting pipe 5, so that the functions of air guiding and air leakage prevention are achieved.
Preferably, the connecting pipe 5 is a hose, so that the service life and the sealing performance of the connecting pipe 5 are ensured.
The utility model discloses a theory of operation:
the pressure switch 4 senses the air pressure of the upper air chamber 30, so that when the water level of the washing chamber 1 changes, the air pressure of the lower air chamber 31 changes, and then the air pressure change needs to be conducted through the sponge 6, until the air pressure of the upper air chamber 30 changes, the pressure switch 4 cannot detect the water level of the washing chamber 1. The air pressure change due to the water level change is stable and continuous, and through the above process, the air pressure change finally passes through the sponge 6 to reach the pressure switch 4, and the pressure switch 4 can normally detect the water level. For a momentary air pressure change, i.e. a sudden rise in air pressure caused by a rapid door closing, during the time when the air pressure change passes through the sponge 6, the air pressure inside the washing chamber 1 is rapidly restored, and the air pressure in the lower air chamber 31 is reduced to the original level, at which time the conductive air pressure change disappears, and the rise in air pressure in the upper air chamber 30 is not caused, and thus the false triggering of the pressure switch 4 is not caused.
Example two: as shown in fig. 3, a difference from the first embodiment is that the sponge 6 is respectively disposed at two ends in the connecting pipe 5, and includes a first sponge section 60 and a second sponge section 61, the first sponge section 60 is disposed near the vent 32, and the second sponge section 61 is disposed near the pressure switch 4, which can also prevent the pressure switch 4 from being triggered by mistake.
In addition, a vent hole 32 is provided at one side of the air chamber 3, and the vent hole 32 communicates the air chamber 3 with the connection pipe 5, and also has the functions of air guiding and air leakage prevention.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
