Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a foam generator for a cleaning device that constantly generates foam and uses the foam to wash dishes and the like.

BACKGROUND TECHNOLOGY Conventionally, the foam generating configuration of this type of cleaning device is
As shown in Fig. 2, gas is sent from the bottom of a liquid containing a surfactant (hereinafter referred to as detergent liquid) to generate foam in detergent liquid 2 in container 1. . In the case shown in FIG. 1, gas sent from an air supply pipe 3 passes through a backflow prevention part 4 and is discharged from holes 6 of a foam board 5 in the detergent solution into the detergent solution, generating bubbles in the detergent solution 2. It was hot. In addition, in the case shown in FIG. 2, the container 7 is partitioned by a foam board 8 that allows gas to pass through but not liquid, and the gas sent from the air pipe 9 flows through the foam board 8 into the detergent liquid 10. It was something that foamed when it was served in the water.

Problems to be Solved by the Invention However, in the conventional method as described above, since air is supplied from below the detergent solution, a pressure drop corresponding to the height of the detergent solution occurs, and as a result, the supply pressure must be increased. I needed to. In particular, in the conventional example shown in FIG. 2, an extremely high pressure was required. In addition, in the case shown in FIG. 1, the amount of air supplied changed due to changes in the water level, and therefore the generation of bubbles was not constant.

The purpose of the foam generator for a cleaning device of the present invention is to solve these conventional problems and to generate steady foam with extremely low pressure loss.

Means for Solving the Problems In order to solve the above problems, the foam generator of the cleaning device of the present invention has a floating part that floats on the surface of the detergent liquid in a container, and a foam generator that is suspended in the detergent liquid by this floating part. a fixing part, and attaching a distal end of an air pipe inserted into the container from the upper end opening to the fixing part,
The distance from the gas outlet at the tip of the air pipe to the liquid level is kept constant.

Effect According to the above configuration, the gas sent from the air pipe is released into the detergent liquid while generating bubbles from the gas outlet of the air pipe, but in this case, even if the liquid level becomes high or The floating part moves up and down even when it is low,
As the fixed part also moves up and down, the distance (depth) between the gas outlet of the air pipe and the liquid level can be kept constant regardless of the amount of detergent liquid.As a result, the pressure drop is low regardless of the amount of liquid. This allows constant whisking.

Embodiment An embodiment of the present invention will be described below with reference to FIG. A detergent liquid 12 is contained in a container 11, and a floating part 14 such as a hollow float ball with a mesh-shaped fixed part 13 suspended in the detergent liquid 12 is floating on the surface of the detergent liquid 12. A distal end portion of an extensible air pipe 15 inserted through the upper opening of the container 11 is attached to the fixing portion 13 .
Note that the fixing portion 13 may be a wire frame or a punched hole, and in short, it is sufficient that it has an opening through which the detergent solution can freely enter and exit.

Now, the gas sent from the air pipe 15 is released into the detergent liquid 12 from the gas outlet 16 of the air pipe 15 while generating bubbles. In this case, even if the liquid level becomes high or low, the floating part 14 moves up and down, and the fixed part 13 also moves up and down accordingly, so the distance l between the gas outlet 16 of the air pipe 15 and the liquid level is If the supply pressure is constant, the generation of bubbles will be steady. Although this foam is not shown, it is supplied to a dishwashing tank, for example.
It is used to wash dishes, etc.

Effects of the Invention As described above, the foam generator of the cleaning device of the present invention has the following features:
Although the generation of bubbles is steady and generates bubbles,
Since the distance between the gas outlet of the air supply pipe and the liquid level is constant, the conventional problem can be solved without increasing the supply pressure unnecessarily even when there is a large amount of detergent liquid.
