Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for a dental spittoon, and particularly to a chair on which a patient is placed for treatment, a lighting device for illuminating an affected area, and a table on which treatment instruments are placed. and a spittoon part for a patient to gargle, the dental treatment unit is configured to move the chair and/or spittoon part to a predetermined position, and the chair has an auto-return mechanism. During the auto-return operation of the chair in connection with the operation, for example, the bowl of the spittoon part moves to a position where it is easy to gargle, and after the chair operation and the bowl operation are completed, water for gargling is provided at a predetermined level. The water fountain is sprayed for a certain period of time, and after the fountain stops, washing water for washing the bowl is spouted out for a predetermined period of time, and then the bowl returns to its original predetermined position. In order to improve the operability of these functions,
The aim is to make the treatment more efficient.

In a dental treatment unit, it is already known that the bowl is washed in conjunction with gargling, so that the bowl is always kept clean after gargling.
If the patient wants to gargle after or during treatment, most chairs are moved to a position where the patient can gargle, and for this reason, many are equipped with an auto-return switch to return the chair to the gargling position. However, in the above-mentioned conventional method, even if the chair is in the gargling position, in order to gargle, it is necessary to indicate the intention to gargle, for example, by pressing a switch for the gargling fountain, and the automatic return operation of the chair and the gargling water spouting operation are required. The operation and spouting of washing water for washing the pot were not continuous, resulting in poor operability, and it took time from the auto-return of the chair to the washing of the pot, resulting in poor treatment efficiency.

The present invention has been made in view of the above-mentioned circumstances, and in particular links the movement of the chair to the gargling position, the spraying of gargling water, and the spraying of water for washing the bowl, thereby improving operability. This aims to shorten the time and at the same time, smooth the flow of medical treatment and improve the efficiency of treatment.

The figure is an overall configuration diagram for explaining one embodiment of the present invention. In the figure, 10 is a central control unit, 20 is a chair vertical movement control unit, 30 is a chair back elevation control unit, and 40 is a chair back elevation control unit. The spittoon part, 50 is a chair operation switch part, 60 is a switch for gargling water fountain, 70 is a wash reset switch, M is a motor, R is a potentiometer, V is a solenoid valve, and spittoon part 4
0 is limit switch SW ₄₁ by motor M ₄₀
It is possible to move horizontally between SW ₄₂ and SW 42, and the gargling fountain and washing water are each equipped with a solenoid valve V ₄₁ ,
It is designed to be ejected through the V ₄₂ . The chair operation switch section 50 is a switch for moving the chair up and down.
SW ₅₁ , SW ₅₂ ; Switch for raising and lowering the chair back board SW ₅₃ ,
SW ₅₄ ; Chair auto return switch SW ₅₅ ;
SW ₅₆ ; Consists of memory setting switch SW ₅₇ , memory storage switch SW _58, etc. First, operate the vertical movement of the chair with switches SW ₅₁ and SW ₅₂ to reach the desired height, and then adjust the back plate of the chair ( The back crest) is operated with switches SW ₅₃ and SW ₅₄ to bring it into the desired undulation state, and then the lighting equipment and table section (not shown) are manually set in the position that is most convenient for diagnosis, and in this state, the memory storage switch SW ₅₈ is turned on. Press to store this state in a predetermined memory (RAM) in the central control unit 10, and from then on,
When the memory setting switch SW ₅₇ is pressed, the chairs, lighting equipment, and table are automatically set to the memorized state. The present invention is applied to the above-mentioned dental unit, and when the automatic return switch SW ₅₅ of the chair is pressed, all motors other than those for vertical movement of the chair are stopped by the limit switch in the same manner as in the prior art. In other words, the height of the chair does not change, only the ups and downs change until the chair reaches the gargling position.At this time, in the present invention,
The motor for moving the pot is also driven, and the limit switch is activated.
Driven until SW ₄₁ is activated. By picking up the movement of the limit switches on the chair and the bowl, it is possible to tell whether all the movements have been completed or not, and at the point of completion, a fountain for gargling is spouted for a certain predetermined time (adjustable), After the fountain finishes, water for washing the pots is squirted out for a predetermined period of time to wash the pots. Thereafter, when a switch other than the chair auto-return switch is turned on, or when the pot reset switch 70 is turned on, the pot returns to the limit switch SW ₄₂ and returns to its original state.

As is clear from the above description, according to the present invention, the gargling position of the chair, the position of the bowl of the spittoon part, the spraying of gargling water, and the spraying of water for washing the bowl are made into a series of continuous operations. It is possible to shorten the time required for these operations, smooth the flow of medical treatment, and improve treatment efficiency.
