Description

Technical Field

[0001] The utility model belongs to the technical field of toilets and relates to a water tank assembly of a wall-mounted intelligent toilet. Background Art

[0002] The toilet is an indispensable bathroom equipment in every household in today's life. It generally includes a ceramic base with a pelvis and a water tank. An inlet valve for connecting to an external water pipe and an outlet valve connected to the pelvis through a flushing pipe are installed in the water tank. Water is filled into the water tank through the inlet valve for storage. When it is needed, the water temporarily stored in the water tank is controlled by the outlet valve to be discharged into the pelvis through the flushing pipe, thereby flushing the pelvis.

[0003] With the continuous advancement of technology, smart toilets have gradually entered the public eye. Compared with ordinary mechanical toilets, the biggest highlight of smart toilets is their diverse functions. For the flushing function, the functional components of the current smart toilets for flushing include a water inlet valve, a switching valve, and a control circuit board. The water inlet valve and the switching valve are connected to the circuit board through wires, and the control circuit board controls the opening and closing of the two. When in the starting state, the water inlet valve introduces water from the external water pipe. After passing the water into the switching valve, the control circuit board controls the two valve plates in the switching valve. Control is performed to realize that the switching valve supplies water to the upper flush pipe or the lower flush pipe connected to the pelvic cavity, so as to realize the upper flush function or the lower flush function of the toilet. It is well known that the installation space in the toilet is relatively limited. Due to the setting of the circuit board, the water inlet valve and the switching valve, and the numerous sensors and wires and other components arranged inside the toilet, the installation space left in the toilet is very limited, and it is not enough to install a water tank therein to ensure that the toilet has the water storage function. Therefore, the water tank structure is generally abandoned directly, and the flushing function of the toilet is directly realized by the cooperation of the water inlet valve, the switching valve and the control circuit board.

[0004] However, the above-mentioned smart toilets have great disadvantages during use. Specifically, the flushing of the smart toilet is completely dependent on the cooperation of the smart water pump and the external water pipe. However, water outages and low-pressure water supply are inevitable in life. In this case, the water pump cannot fully pump water to supply the pelvic cavity, and thus cannot achieve the function of flushing the pelvic cavity, which in turn causes certain limitations in the use of smart toilets. Summary of the invention

[0005] The purpose of the utility model is to address the above-mentioned problems in the existing technology and to propose a water tank assembly for a wall-mounted smart toilet. The technical problem to be solved by the utility model is: how to reduce the usage limitations of the smart toilet while ensuring the installation space for electrical components.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a water tank assembly of a wall-mounted intelligent toilet, the wall-mounted intelligent toilet includes a seat body, the seat body has a pelvic cavity and an installation cavity located behind the pelvic cavity, the water tank assembly includes a tank body, a water pump, a switching valve and a water inlet valve, characterized in that the tank body is connected to the installation cavity and is arranged close to one side of the pelvic cavity, the bottom of the tank body is stepped along the width direction of the seat body to form a first step cavity, a second step cavity and a third step cavity that are connected in the tank body, and the depths of the first step cavity, the second step cavity and the third step cavity decrease successively, the switching valve and the water inlet valve are connected to the inner bottom wall of the second step cavity, and the water pump is connected to the inner bottom wall of the third step cavity.

[0007] The present application installs a box body in the installation cavity and stores water in the box body through a water inlet valve to ensure that the toilet can still be flushed once when the water supply is cut off or the water pressure is low, thereby achieving the purpose of reducing the limitations of the use of the smart toilet. At the same time, on this basis, in addition to the switching valve, the water inlet valve and the water pump used to supply water to the pelvic cavity are also integrated into the box body in the present application, thereby avoiding that the water pump, the switching valve and the water inlet valve occupy too much space in the installation cavity. The three are carried by the box body to achieve the purpose of reasonably utilizing the space in the installation cavity. At the same time, the present case further optimizes the shape of the box body by setting the bottom of the box body in a stepped shape. Compared with the boxes in the square tube, cylindrical shape and other shapes commonly used in the prior art, the shape of the box body in this case can It is more suitable for the installation cavity. While ensuring that the water storage capacity of the box itself meets the requirements, the shape of its outer wall is used to make way for various components in the installation cavity, thereby avoiding the situation where the components cannot be installed due to the existence of the box. Furthermore, the present application reasonably plans the installation positions of the water pump, the switching valve and the water inlet valve in the box, and sets the water pump in the third step cavity to ensure that the water in the water tank is effectively pumped out, avoiding the situation where the pelvic cavity is not cleaned due to insufficient water supply during the flushing process of the toilet. The water inlet valve and the switching valve are set in the second installation cavity. On the premise of ensuring that the water tank effectively accommodates the water inlet valve and the switching valve, interference between the water inlet valve and the switching valve and the water pump is avoided, and it also ensures that it is more convenient to lay pipes between the three.

[0008] In the water tank assembly of the wall-mounted smart toilet, the bottom of the tank body abuts against the bottom wall of the installation cavity, the inner wall of the installation cavity on the side away from the pelvic cavity has an abutting edge along the width direction of the seat body, and the side of the tank body facing away from the pelvic cavity has an inner convex edge along the width direction of the seat body, and the inner convex edge abuts against the abutting edge and is screwed and locked by fasteners. Through this arrangement, the tank body can be pre-installed and stabilized in the installation cavity, and the abutting edge and the inner convex edge cooperate to achieve positioning of the tank body, and the fasteners are used for secondary connection and locking to ensure stable installation of the tank body.

[0009] In the water tank assembly of the wall-mounted smart toilet, a fixing hole is provided on the abutting edge, and a long strip-shaped connecting hole is provided on the inner convex edge in the length direction, and the fastener is passed through the connecting hole and screwed with the fixing hole. Through this arrangement, the box body can be displaced and adjusted along the width direction of the seat body in the installation cavity, and then locked by the cooperation of the fastener, the connecting hole and the fixing hole, ensuring that the position of the box body can be adaptively adjusted according to the installation requirements of the components.

[0010] In the water tank assembly of the wall-mounted intelligent toilet, a connecting groove is provided on the seat body between the installation cavity and the pelvic cavity, the installation cavity and the pelvic cavity are connected through the connecting groove, and a U-shaped overflow plate is provided on the outer wall of the top of the box body close to the pelvic cavity, and the overflow plate is shorter than the length of the connecting groove, and the overflow plate extends into the connecting groove and abuts against the bottom wall of the connecting groove. When the box body is installed, the abutment and cooperation between the overflow plate and the bottom wall of the connecting groove can further ensure the stability of the pre-positioning of the box body. At the same time, in the subsequent use process, the water storage amount of the water inlet valve into the box body may be greater than the actual capacity of the box body. At this time, due to the presence of the overflow plate, the excess water in the box body can be discharged into the pelvic cavity of the seat body through the overflow plate and the connecting groove, thereby preventing the water in the box body from overflowing into the installation cavity and causing irreversible damage to the components.

[0011] In the water tank assembly of the wall-mounted smart toilet, the bottom wall of the connecting groove and the overflow plate are both inclined downward toward the pelvic cavity, so as to ensure that the water flows into the pelvic cavity under the guidance of the overflow plate and the water in the tank is kept at a safe water level.

[0012] In the water tank assembly of the wall-mounted smart toilet, the outer bottom wall of the tank body located directly below the third step cavity has an annular rib, and the annular rib abuts against the inner bottom wall of the installation cavity. Due to the further design of the tank body shape, compared with the water tank in the prior art, the contact area between the tank body and the bottom of the installation cavity is smaller, which will inevitably cause a greater pressure on the bottom of the tank body when storing water, and the provision of the annular rib can effectively improve the structural strength of the bottom of the tank body.

[0013] Compared with the prior art, the water tank assembly of this wall-mounted intelligent toilet has the following advantages:

[0014] 1. By setting the bottom of the box in a stepped shape, a first step cavity, a second step cavity and a third step cavity which are connected are formed inside the box. The depths of the first step cavity, the second step cavity and the third step cavity decrease successively along the width of the box. This avoids the defect of interference with electrical components during installation while ensuring the volume of the box, thereby ensuring the installation space of electrical components and reducing the limitations of toilet use.

[0015] 2. The water pump, water inlet valve and switching valve are all integrated in the box to prevent their installation from affecting the installation of electrical components. Secondly, the water pump is installed in the third step cavity, and the water inlet valve and switching valve are installed in the second installation cavity to achieve the effect of reasonable planning and installation layout of the three in the box.
