Document Type and Number:
Japanese Patent JP2023072978
Kind Code:
A
Abstract:
To disclose one example of a water supply device which can inhibit an electric pump from operating at an excessively high rotation speed while securing a necessary water supply amount.SOLUTION: In target pressure control, a value of a target pressure is increased when a water supply amount is in an increasing state and the value of the target pressure is decreased when the water supply amount is in a decreasing state. Thus, the water supply amount is increased in the increasing state and the water supply amount is decreased in the decreasing state. Thus, in a water supply device 1, an operation state of an electric pump 3 is changed according to the necessary water supply amount. Further, the electric pump 3 can be inhibited from operating at an excessively high rotation speed while the necessary water supply amount is secured.SELECTED DRAWING: Figure 1
