It consists of a cover part that is detachably attached to the open window of the box part.

This conventional water supply control box has a structure in which an elastic body made of rubber or the like is interposed between the box part and the cover part, and the cover part is attached to the box part by threading a large number of screws. This prevents the cover part from wobbling and allows it to be reliably attached to the box part.

However, with such conventional water supply control boxes, there is a problem that the elastic body sandwiched over a wide area between the box part and the cover part easily deteriorates and is not durable enough to prevent the cover part from rattling. . In addition, due to the necessity of threading a large number of screws,
There is a problem that attaching and detaching the cover part is troublesome.

In addition, this type of water supply control box has a structure in which the sensing part is attached to the mounting frame using a roller catch (see Japanese Utility Model Publication No. 154469/1983), and a sensing part cover made of synthetic resin that utilizes the elasticity of the synthetic resin. There is also a known structure in which the sensor is attached to the sensing part (see Japanese Utility Model Application Publication No. 159464/1983), and it is also possible to apply such a mounting structure that utilizes elasticity to the attachment between the cover part and the box part. However, those that attach the cover to the box using only elasticity have poor durability and may become rattled due to long-term use or frequent attachment and detachment.Moreover, those that use a roller catch like the former have a complicated structure. However, there are problems in that the number of parts increases and the cost also increases.

(Purpose of the invention) The present invention was made to solve these problems, and its purpose is to provide a cover that can be easily attached and removed, and that is durable enough to prevent the cover from wobbling. An object of the present invention is to provide a water supply control box that can prevent the above problems.

(Structure) In order to achieve the above-mentioned object, the water supply control box according to the present invention includes a box part that houses the water supply control mechanism and is fixedly installed with an open window in a part, and an open box part of the box part.
