Description

Technical Field

[0001] This application relates to the field of water dispenser technology, and in particular to a water dispenser water supply device. Background Technology

[0002] The authorized patent application CN201320194681.0 discloses a water supply device for a water heater. In existing water heater tanks, the water level fluctuates between the two chambers, causing pressure changes in the water supplied to the heating element. This results in hot and cold water mixing, making it impossible to guarantee that all drinking water is boiled. The water supply device provided by this invention features a water tank with a trough, an outlet pipe at the bottom of the trough, and an inlet pipe connected to the outlet of a water pump supplying water to the trough. The inlet of the water pump is located at the bottom of the tank. The trough also includes a return water device to guide water with excessively high levels back to the tank. A float at the bottom of the trough is connected to the water heater's control system. When the water heater is operating, the water level in the trough remains constant, preventing pressure changes in the outlet pipe and avoiding mixing of hot and cold water, making it safer and more convenient to use.

[0003] However, in the aforementioned existing technologies, whether the water tank is fixed to the inner wall of the water tank with bolts or with non-toxic glue, the operation is often quite complicated and inconvenient for installation and disassembly for cleaning. While installing the water tank on the outside of the water tank makes it convenient to clean each item individually, it increases the installation space and brings inconvenience to the installation and use of the water dispenser. Utility Model Content

[0004] To address the issue that existing water supply devices for water heaters, whether using bolts to fix the water tank to the inner wall of the water tank or using non-toxic glue, are often complex to operate and inconvenient to install and disassemble for cleaning, while installing the water tank on the outside of the water tank allows for easy cleaning, it increases the installation space and causes inconvenience to the installation and use of the water heater, this application provides a water supply device for a water heater.

[0005] The water supply device for a water dispenser provided in this application adopts the following technical solution:

[0006] A water supply device for a water dispenser includes a water tank with a detachable water storage trough inside. A water outlet pipe is located at the lower part of one side of the water storage trough, and a water inlet pipe is located at the bottom. The water inlet pipe is connected to the outlet of a water pump that supplies water to the water storage trough. A return water opening is located at the upper end of the water storage trough. A fixing frame is fixedly installed at the top of one end of the return water opening. The fixing frame is snapped onto a side wall of the water tank. A U-shaped mounting base is located on the outer side of the side wall of the water tank. The fixing frame is snapped into the interior of the U-shaped mounting base. Limiting components for fixing the fixing frame are symmetrically arranged inside the U-shaped mounting base.

[0007] Preferably, the outlet of the water storage tank is lower than the highest liquid level of the water tank.

[0008] Preferably, the U-shaped mounting base has a mounting hole in the middle that matches one end of the fixed frame.

[0009] Preferably, the U-shaped mounting base has symmetrically formed cavities at both ends. The limiting component includes a sliding plate that is slidably installed in the cavity. One end of the sliding plate is fixedly provided with an insert rod at equal intervals, and the other end is fixedly provided with a connecting rod at equal intervals. The other ends of the multiple insert rods pass through the cavity and extend to the outside of the U-shaped mounting base. The other ends of the multiple connecting rods pass through the cavity and extend to the outside of the U-shaped mounting base and are provided with baffles. A spring is sleeved in the cavity. One end of the spring is fixedly connected to the sliding plate, and the other end is fixedly connected to the inner wall of the cavity.

[0010] Preferably, the fixed frame has multiple symmetrically spaced insertion holes on its outer side that are adapted to the insertion rod, and a handle is fixedly connected to the side of the baffle away from the connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] During installation, the water supply device for this water dispenser is installed by pulling the baffle with the handle to insert the water storage tank 2 into the water tank. Releasing the handle causes the spring to return to its elasticity, pushing multiple rods into the multiple holes on the outside of the fixed frame, thus securing the fixed frame. Similarly, during disassembly, pulling the baffle with the handle moves it away from the U-shaped mounting base, causing the rods to leave the holes and releasing the fixed frame. The fixed frame can then be lifted upwards to remove the water storage tank from the water tank, facilitating installation and disassembly and making subsequent cleaning easier.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution:

[0019] A water supply device for a water dispenser includes a water tank 1, a water storage tank 2 detachably installed inside the water tank 1, an outlet pipe 15 on the lower part of one side of the water storage tank 2, and an inlet pipe 3 at the bottom. The inlet pipe 3 is connected to the outlet of a water pump that supplies water to the water storage tank 2. A return water opening is provided at the upper end of the water storage tank 2, and a fixing frame 4 is fixedly installed at the top of one end of the return water opening. The fixing frame 4 is snapped onto one side wall of the water tank 1. A U-shaped mounting seat 5 is provided on the outer side of the side wall of the water tank 2, and the fixing frame 4 is snapped into the inside of the U-shaped mounting seat 5. Limiting components for fixing the fixing frame 4 are symmetrically arranged inside the U-shaped mounting seat 5.

[0020] The outlet of the water storage tank 2 is lower than the highest liquid level of the water tank 1. When the water level in the water storage tank 2 is too high, the water will be drawn back into the water tank 1 through the outlet.

[0021] The U-shaped mounting base 5 has a mounting hole 6 in the middle that matches one end of the fixed frame 4.

[0022] The U-shaped mounting base 5 has symmetrically opened cavities 7 at both ends. The limiting component includes a sliding plate 8 that is slidably installed in the cavity. One end of the sliding plate 8 is fixedly provided with insert rods 10 at equal intervals, and the other end is fixedly provided with connecting rods 9 at equal intervals. The other ends of the multiple insert rods 10 pass through the cavity and extend to the outside of the U-shaped mounting base 5. The other ends of the multiple connecting rods 9 pass through the cavity and extend to the outside of the U-shaped mounting base 5 and are provided with baffles 11. A spring 12 is sleeved inside the cavity 7. One end of the spring 12 is fixedly connected to the sliding plate 8, and the other end is fixedly connected to the inner wall of the cavity 7.

[0023] The outer side of the fixed frame 4 has multiple symmetrically spaced insertion holes 13 that are compatible with the insertion rod 10, and a handle 14 is fixedly connected to the side of the baffle 11 away from the connecting rod 9.

[0024] During installation, pull the baffle 11 away from the U-shaped mounting base 5, which will cause the connecting rod 9, baffle 11, and insertion rod 10 to move synchronously. The movement of baffle 11 within the cavity 7 will compress the spring 12, and the movement of insertion rod 10 will retract it into the cavity 7. Then, install the water storage tank 2, aligning the fixing frame 4 at the upper end of the water storage tank 2 with one side wall of the water tank 1. Insert the water storage tank 2 into the water tank 1, inserting one end of the fixing frame 4 into the mounting hole 6 in the middle of the U-shaped mounting base 5. Release the handle 14, at which point the spring 12 will return to its original position. The force pushes the slide plate 8 and the insert rod 10 towards the center of the U-shaped mounting base 5, so that the multiple insert rods 10 are inserted into the multiple insertion holes 13 on the outside of the fixed frame 4, thereby limiting and fixing the fixed frame 4. Similarly, when disassembling, the baffle 11 is pulled by the handle 14 and moved away from the U-shaped mounting base 5, which drives the insert rods 10 away from the insertion holes 13, releasing the limitation on the fixed frame 4. The fixed frame 4 can then be lifted upwards, and the water tank 2 can be removed from the water tank 1, which facilitates installation and disassembly and makes it easier to clean them one by one later.
