Patent Description:
In order to save an occupied space of a building, the overall volume of a water tank of a toilet tends to be smaller and smaller. As shown in a hidden water tank with a detergent storage box, which is disclosed in <CIT>, a water tank is provided with a mounting seat fixedly protruding to a mounting window, and a cover plate (i.e. a panel) covers the mounting window and is fixedly connected to the mounting seat. However, with the diversification of product functions, there are more and more assemblies to be replaced and repaired inside the water tank, such as water inlet/outlet valves, intelligent modules, etc. The disassembly and assembly operations of the above assemblies bring troubles to a small-volume water tank structure and make it difficult to disassemble and assemble. Document <CIT> gives an example of a device for fastening an actuating element to a flush-mounted cistern, having at least one spacer bolt which engages in an opening of a holding element and has an external toothing which engages with an internal toothing of the said opening. However, more sophisticated mechanisms for facilitating assembly and disassembly of internal assemblies are still needed.

To this end, the present invention provides a hidden water tank for improving disassembly and assembly of internal assemblies to effectively solve the above problems.

In order to achieve the above objective, the present invention provides the following technical solution:
a hidden water tank for improving disassembly and assembly of internal assemblies, the hidden water tank comprising a water tank body provided with a mounting window, and at least one mounting seat positioned at an edge of the mounting window and used for assembling a connecting panel, wherein the mounting seat is movably connected and arranged on the water tank body, and by means of the movement of the mounting seat, the mounting seat can be switched between a first positioning state in which the mounting seat protrudes in a direction toward the center of the mounting window and a second positioning state in which the mounting seat retracts toward the edge of the mounting window.

The hidden water tank of the invention is particular in that the arrangement of movable connection of the mounting seat is a hinged arrangement or a slidable connection.

When the mounting seat is a hinged arrangement, further preferably, a plane where the mounting window is located is defined as a first plane, an axial direction of a hinge shaft connecting the mounting seat and the water tank body is perpendicular to the first plane, and the mounting seat swings on a parallel plane parallel to the first plane and can be switched between the first positioning state and the second positioning state.

Still more further preferably, the mounting seat is arranged on an inner wall surface of the water tank body.

More further preferably, the inner wall surface of the water tank body is further provided with a stop portion in a protruding manner.

Further preferably, a plane where the mounting window is located is defined as a first plane, an axial direction of a hinge shaft connecting the mounting seat and the water tank body is parallel to the first plane, and the mounting seat swings on a perpendicular plane perpendicular to the first plane and can be switched between a first positioning state and a second positioning state.

More further preferably, a fixed seat is fixedly connected to the inner wall surface of the water tank body, and the mounting seat is hinged to the fixed seat.

When the mounting seat is a slidable arrangement, further preferably, the inner wall surface of the water tank body is provided with a slide groove, and the mounting seat is slidably fitted to the slide groove in the inner wall surface of the water tank body.

Further preferably, the mounting seat is provided with a mounting hole.

With the technical solution of the present invention, the beneficial effects are as follows.

The mounting window is enabled to have a larger mounting area by means of a second positioning state of retracting to the edge of the mounting window, and the mounting window can be assembled and connected to the connecting panel by means of a first positioning state of protruding in a direction toward the center of the mounting window. Without changing the size of original components (such as the size of the mounting window, the connecting panel, etc.), by means of a movably arranged mounting seat, the requirements of disassembling and assembling internal assemblies can be met, thereby effectively solving the problem that it is difficult to disassemble and assemble the internal assemblies in a small-sized water tank structure in the prior art, and achieving a simple structure and being easy to implement.

The present invention provides drawings to further illustrate the various embodiments. The drawings, which are part of the disclosure of the present invention, are mainly used to illustrate the embodiments and can explain the operation principle of the embodiments together with the relevant explanation in the description. With reference to these contents, a person of ordinary skill in the art should be able to understand the advantages of the present invention. Assemblies in the drawings are not drawn to scale, and like reference numerals are usually used to indicate like assemblies.

The present invention will now be further described with reference to the drawings and particular embodiments.

In the following embodiments, the term "outward" or "inward" is defined relative to the position of a mounting window, "outward" refers to a direction in which a water tank body faces the mounting window, and "inward" refers to a direction in which the mounting window faces the water tank body. The term "forward" refers to a direction in which an inner side wall of the water tank body faces an outer wall surface of the water tank body, and the term "backward" refers to a direction in which the outer wall surface of the water tank body faces the inner side wall of the water tank body. The terms "upward" and "downward" refer to a vertical direction of the water tank in an assembled state.

Referring to <FIG> and <FIG>, this embodiment provides a hidden water tank that improves disassembly and assembly of internal assemblies, the hidden water tank comprising a water tank body <NUM> and a mounting seat <NUM> for a connecting panel (not shown), wherein the water tank body <NUM> is provided with a mounting window <NUM>, and a plane where the mounting window <NUM> is located is defined as a first plane. Specifically, when the water tank is assembled, the mounting window <NUM> is a vertical window, that is, the first plane is a vertical plane. The mounting seat <NUM> is movably arranged on the water tank body <NUM>, specifically, the mounting seat <NUM> is hinged on the water tank body <NUM>, and more specifically, an axial direction of a hinge shaft (not shown) connecting the mounting seat <NUM> and the water tank body <NUM> is perpendicular to the first plane. The mounting seat <NUM> swings on a parallel plane (also being a vertical plane) parallel to the first plane and can be switched between a first positioning state (as shown in <FIG>) in which the mounting seat protrudes in a direction toward the center of the mounting window <NUM> and a second positioning state (as shown in <FIG>) in which the mounting seat retracts toward an edge of the mounting window.

When it is necessary to assemble or disassemble an assembly such as a water inlet valve into or from the water tank body <NUM>, in the state of <FIG>, the mounting seat <NUM> is toggled, so that the mounting seat <NUM> swings downward to the second positioning state in which the mounting seat retracts to the edge of the mounting window, as shown in <FIG>, thus the effective area of the mounting window <NUM> for the access of the assembly can be increased. In this specific embodiment, the mounting seat <NUM> can swing to be completely hidden in the water tank body <NUM>, which does not affect the access of the assembly at all. After the operation is completed, the mounting seat <NUM> is toggled to swing upward, and the mounting seat <NUM> is switched to the first positioning state in which the mounting seat protrudes in a direction toward the center of the mounting window <NUM>, thus realizing a normal fixed assembly with the connecting panel. Without changing the size of original components (such as the size of the mounting window <NUM>, the connecting panel, etc.), the problem that it is difficult to disassemble and assemble the internal assemblies in a small-sized water tank structure in the prior art can be effectively solved, and the structure is simple and easy to implement.

Further preferably, in this embodiment, the mounting seat <NUM> is arranged on an inner wall surface of the water tank body <NUM>, thus it can give way to the mounting of the connecting panel, so that the connecting panel can be better attached to an outer wall surface of the water tank body <NUM>, and the assembly is more stable and simpler. Of course, in other embodiments, the mounting seat <NUM> can also be arranged on the outer wall surface of the water tank body <NUM>, etc. When the mounting seat <NUM> is arranged on the outer wall surface of the water tank body <NUM>, the mounting seat <NUM> itself protrudes from the outer wall surface of the water tank body <NUM>. In order to allow the connecting panel to be attached to the outer wall surface of the water tank body <NUM>, a clearance groove can be arranged at a position of the connecting panel corresponding to the mounting seat <NUM>. When covered, the mounting seat <NUM> is accommodated in the clearance groove, and other positions of the connecting panel can be well attached to the outer wall surface of the water tank body <NUM>.

Further preferably, in this embodiment, the inner wall surface of the water tank body <NUM> is further provided with a stop portion <NUM> in a protruding manner. When the mounting seat <NUM> swings to be perpendicular to an outer edge of the mounting window <NUM>, it indicates that the mounting seat moves to a position for the connecting panel, and at this time, the mounting seat is stopped and limited by the stop portion <NUM> to realize positioning. That is, in this specific embodiment, the mounting seat <NUM> swings in a lower semicircle (i.e., a lower half of a circle), and the stop portion <NUM> is located above the mounting seat <NUM>. When the mounting seat <NUM> swings upward to a position for assembly, the mounting seat is stopped by the stop portion <NUM>, which limits the mounting seat from continuing to swing upward, so that the mounting seat <NUM> can be quickly positioned and the operation is simpler. Of course, in other embodiments, if the mounting seat <NUM> swings in an upper semicircle (i.e., an upper half of a circle), the stop portion <NUM> is located below the mounting seat <NUM> correspondingly. When the mounting seat <NUM> swings downward to a position for assembly, the mounting seat is stopped by the stop portion <NUM>, which limits the mounting seat from continuing to swing downward. Alternatively, there is no need for the limit of the stop portion <NUM>, and so on.

Further, the movable arrangement of the mounting seat <NUM> enables the mounting seat <NUM> to realize a fine adjustment in its movable direction, so as to be better aligned with a mounting structure of the connecting panel.

Further preferably, in this embodiment, the mounting seat <NUM> is provided with a mounting hole <NUM>, specifically a screw hole, and the mounting seat is fixedly assembled to the connecting panel by means of the mounting hole <NUM>. Specifically, the connecting panel is also provided with a mounting hole, and then a bolt is used to pass through the mounting hole in the connecting panel and the mounting hole <NUM> of the mounting seat <NUM> in sequence for screw connection and fixation. Of course, in other embodiments, the mounting structure on the mounting seat <NUM> can also be replaced by other structures, such as clamping grooves, hook and loop fasteners, etc., as long as it can be mounted to and match the structure on the connecting panel.

This embodiment provides a hidden water tank that improves disassembly and assembly of internal assemblies, the structure of which is substantially the same as the structure of embodiment I except in that referring to <FIG>, in this embodiment, an axial direction of a hinge shaft <NUM> connecting the mounting seat <NUM> and the water tank body <NUM> is parallel to the first plane, and the mounting seat <NUM> swings (i.e., swings back and forth) on a perpendicular plane perpendicular to the first plane to be switched between a first positioning state (as shown in <FIG>) and a second positioning state (as shown in <FIG>).

As in this specific embodiment, when it is necessary to assemble or disassemble an assembly such as a water inlet valve into or from the water tank body <NUM>, in the first positioning state shown in <FIG>, the mounting seat <NUM> is toggled forward, so that the mounting seat <NUM> swings forward to be switched to the second positioning state in which the mounting seat retracts to the edge of the mounting window, as shown in <FIG>, thus the effective area of the mounting window <NUM> for the access of the assembly can be increased and the operation is convenient. After the disassembly and assembly operations of the internal assemblies are completed, in the second positioning state shown in <FIG>, the mounting seat <NUM> is toggled backward, so that the mounting seat <NUM> swings backward to the first positioning state in which the mounting seat protrudes in a direction toward the center of the mounting window, as shown in <FIG>, thus realizing a normal fixed assembly of the connecting panel and the mounting seat <NUM>.

More further preferably, in this embodiment, a fixed seat <NUM> is fixedly connected to the inner wall surface of the water tank body <NUM>, and the mounting seat <NUM> is hinged to the fixed seat <NUM>, that is, the water tank body <NUM> is hinged to the mounting seat <NUM> by means of the fixed seat <NUM> arranged on the water tank body. With such an arrangement, when the mounting seat <NUM> is in the first positioning state, as shown in <FIG>, the mounting seat does not interfere with the mounting of the connecting panel, so that the connecting panel can be well attached to the outer wall surface of the water tank body <NUM>.

More specifically, a U-shaped opening (not indicated) with an outward opening is formed at an outer end of the fixed seat <NUM>, a hinge projection <NUM> of the mounting seat <NUM> extends into the U-shaped opening, and a hinged assembly of the U-shaped opening and the hinge projection <NUM> is realized by means of the hinge shaft <NUM>. That is, the hinge shaft <NUM> passes through the hinge projection <NUM>, and two ends of the hinge shaft are fixed on two side walls of the U-shaped opening, so as to realize the hinged assembly of the mounting seat <NUM> and the fixed seat <NUM>. Meanwhile, the hinge projection <NUM> of the mounting seat <NUM> also extends inward to a position where the hinge projection can overlap with the inner wall surface of the water tank body <NUM>. When the mounting seat <NUM> is toggled backward from the second positioning state shown in <FIG> to the first positioning state shown in <FIG>, the hinge projection <NUM> of the mounting seat <NUM> can abut against the inner wall surface of the water tank body <NUM>, thereby limiting the mounting seat <NUM> from continuing to turn backward, and realizing rapid positioning. Of course, in other embodiments, the configuration of the structure and position of the mounting seat <NUM> may not be limited to this. For example, the mounting seat <NUM> may also be directly hinged on a side wall of the water tank body <NUM> surrounding the mounting window <NUM> or hinged on the outer wall surface of the water tank body <NUM>.

This embodiment provides a hidden water tank that improves disassembly and assembly of internal assemblies, the structure of which is substantially the same as the structure of embodiment I except in that referring to <FIG>, in this embodiment, the mounting seat <NUM> is slidably arranged on the water tank body <NUM>, so that the mounting seat <NUM> can slide and protrude in a direction toward the center of the mounting window <NUM> by sliding relative to the water tank body <NUM> to reach a first positioning state (as shown in <FIG>); and the mounting seat can slide and retract to the edge of the mounting window <NUM> to reach a second positioning state (as shown in <FIG>). Switching between the first positioning state and the second positioning state is realized.

When it is necessary to assemble or disassemble an assembly such as a water inlet valve into or from the water tank body <NUM>, in the first positioning state shown in <FIG>, the mounting seat <NUM> is pressed, so that the mounting seat <NUM> slides and retracts to the edge of the mounting window <NUM> to reach the second positioning state shown in <FIG>, thus the effective area of the mounting window <NUM> for the access of the assembly can be increased and the operation is convenient. After the disassembly and assembly operations of the internal assemblies are completed, the mounting seat <NUM> can be pulled out in a direction toward the center of the mounting window <NUM>, which is simple to operate.

Further preferably, in this embodiment, the sliding direction of the mounting seat <NUM> is arranged perpendicular to the side wall of the mounting window <NUM>. Of course, in other embodiments, it can also be tilted at a certain angle, as long as the switching between the first positioning state and the second positioning state can be ensured.

Further preferably, the inner wall surface of the water tank body <NUM> is provided with a slide groove (not shown), and the mounting seat <NUM> is slidably fitted to the slide groove in the inner wall surface of the water tank body <NUM>, thereby realizing a slidable assembly. Moreover, the mounting seat <NUM> is arranged on the inner wall surface of the water tank body <NUM>, which can give way to the mounting of the connecting panel, so that the connecting panel can be well attached to the outer wall surface of the water tank body <NUM>. Of course, in other embodiments, the slidable assembly structure and arrangement position of the mounting seat <NUM> are not limited to this.
