It may be understood that the axis of the flow sensor assembly 50 is eccentrically disposed with respect to the axis 201 of the water replenishment valve assembly 40 or the bathroom waterway 20, so that the axis of the impeller 53 is eccentrically disposed with respect to the axis 201 of the bathroom waterway 20, so that the impeller 53 can be driven to rotate when water flows through the water inlet cavity 13.
Preferably, the axis 201 of the bathroom waterway 20, the axis of the water replenishing channel 30, and the axis of the water replenishing valve assembly intersect at the same point, and the axis of the water replenishing channel 30 is perpendicular to the axis 201 of the bathroom waterway 20. Here, by arranging the axis 201 of the bathroom waterway 20, the axis of the water replenishing channel 30, and the axis of the water replenishing valve assembly to intersect at the same point, the structure of the valve body 10 is more compact, the volume of the valve body 10 is further reduced, and the space required for installing the valve body 10 is reduced.
The invention further provides a wall-mounted furnace, which comprises a wall-mounted furnace body, wherein the wall-mounted furnace body is connected with the water inlet valve 100 of the wall-mounted furnace, and the water inlet valve 100 is used for controlling the opening and closing of the water exchange channel of the wall-mounted furnace plate.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
