Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a cup-type water supply device used for a mouthwash or the like in dental treatment.

Conventional technology and its problems As a water supply device for mouthwash used for dental treatment, there are a fountain type and a cup type. In the case of a cup type, the weight of the cup and the weight of water supplied to the cup are Since the water supply is controlled by the sum of the above, only the cup designated in advance can be used, which is very inconvenient in terms of operability and versatility. Moreover, when a means for detecting the weight is used at the bottom of the cup holder, it is difficult to clean the cup holder from dirt.

The cup type water supply device of the present invention does not depend on the weight detection of the amount of water in the cup, and therefore, does not provide the weight detection means in the lower part of the cup holder to control the amount of water in the cup. It is characterized in that it can be detected, the cup holder can be easily cleaned, and various cups can be used regardless of the weight.

Embodiment FIGS. 1 to 3 are views showing an example of a cup holder suitable for use in the cup type water supply device of the present invention, in which 1 is a cup holder for a dish-shaped container and 2 is a holder. A cup detector 3 including a light receiving detector and the like is a linear convex portion provided on the bottom surface of the dish-shaped container. This linear convex portion 3 prevents the cup from slipping when the cup is placed, prevents contact between water accumulated on the bottom surface of the dish-shaped container and the bottom of the cup, and facilitates drainage. An opening 4 for draining water is provided on one side surface of the dish-shaped container, and water in the dish-shaped container is drained through the opening 4.

When the cup is placed on the cup holder, the cup detector 2
Detects the presence of a cup and supplies water into the cup through a water supply port (not shown). Regarding the amount of water to be supplied, conventionally, a weight detecting means was provided under the cup holder so that the water supply was stopped when the total weight reached a predetermined weight, but in that case, it was specified in advance. Only a cup can be used, and in particular, a paper cup, a plastic cup, and other disposable cups having various shapes and weights cannot be used, which is very inconvenient. Thus, in the present invention, the ultrasonic wave transmitting / receiving device provided near the water supply port detects the water surface in the cup, thereby stopping the water supply when the water surface in the cup reaches a predetermined position. In this way, any desired cup can be used, in particular, a disposable paper cup can be used, which is very hygienic and saves labor such as cleaning and disinfection. This is advantageous in terms of operation and versatility.

The ultrasonic water level detector used to detect the water surface in the cup may be a known one, and its mounting position is attached to a water supply pipe (not shown) arranged at the upper part of the cup holder (or A mounting member for the water level detector may be provided separately.), To accommodate various shapes of the cup,
A pair of ultrasonic transmitters / receivers may be arranged at a position such that the desired water level in the cup can be seen, and at a position facing the desired water level surface so as to have a predetermined angle. Alternatively, one ultrasonic detector may be used to switch between transmission and reception.

In use, when the cup holder 5 is placed on the cup holder 1 and a cup is put in the cup holder 5, the cup detector 2 detects the presence of the cup and the water supply is released after a certain period of time. At the same time, the ultrasonic detector starts operating and monitors the water level in the cup. When the water level in the cup reaches a predetermined water level by water supply, the water level detector detects the water level and stops water supply. This operation will be repeated below.

Effect of the Invention As explained above, according to the present invention, the presence of a cup is detected by the cup detector, then water is supplied for a predetermined time, and the water level in the cup is detected by the ultrasonic detector to determine the water level. Since the water supply is stopped when it reaches a predetermined position, it is not necessary to provide a weight detecting means at the bottom of the cup holder, and a cup with a predetermined weight must be used as in the prior art. Since the cups can be freely selected and used without being subject to restrictions that are not required, disposable cups such as paper cups can be used, and a clean treatment environment can be realized.
