Description

Technical Field

[0001] This utility model relates to water system, and also to a water dispenser with a sterile water tank, dual water supply, and normal pressure water output. Background Technology

[0002] Water dispensers are common drinking water devices. They purify tap water through a filter module, and then use an electric water heater to heat the purified water to boiling. The electric water heater typically has two outlets: one connects directly to the boiling water faucet to provide boiling water; the other, after being cooled by a heat exchanger, connects to the warm water faucet to provide warm water. For water dispensers with multiple faucets (e.g., 4-5), if all faucets are open, the water pressure and flow rate will be low due to the limited water production speed of the filter module, resulting in a poor user experience.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] Regarding the aforementioned technical issues in existing water dispensers with multiple taps, when all taps are open, the water pressure is low and the water output is small due to the limited water production speed of the filter module. The technical solution adopted by this utility model to solve its technical problem is: a water system, which includes: a filter module, an electric water tank, a water storage tank, and a heat exchanger. The inlet of the filter module is connected to a water source through pipe A, and a first booster pump is connected in series on pipe A. The pure water outlet of the filter module is connected to the cold water inlet of the heat exchanger through pipe B. The cold water outlet of the heat exchanger is connected to the inlet of the electric water tank. The first outlet of the electric water tank is connected to at least one hot water tap. The second outlet of the electric water tank is connected to the hot water inlet of the heat exchanger. The warm water outlet of the heat exchanger is connected to at least one warm water tap. The pure water outlet of the filter module is connected to the inlet of the water storage tank through bypass pipe A. The outlet of the water storage tank is connected to the cold water inlet of the heat exchanger through bypass pipe B. A second booster pump is connected in series on bypass pipe B.

[0005] In the water system described above, a first check valve is connected in series on pipe B.

[0006] In the water system described above, a second check valve is connected in series on the bypass pipe B.

[0007] As described above, in the water system, an activated carbon filter element is connected in series on pipe B.

[0008] In the water system described above, the electric water tank is equipped with a pressure sensor for detecting the water pressure inside, and the pressure sensor is connected to the controller.

[0009] In the water system described above, the bypass pipe A is equipped with a solenoid valve, and the water storage tank is equipped with an electronic float valve that controls the start and stop of the solenoid valve.

[0010] As described above, the water system has an overflow outlet at the top of the water storage tank.

[0011] In the water system described above, the hot water tap and the warm water tap are sensor taps.

[0012] This utility model discloses a water dispenser with a sterile water tank, dual water supply, and normal pressure water outlet. The water dispenser adopts the water circuit system described above.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model incorporates a water storage tank. When the electric water heater is full, the pure water produced by the filter module can be temporarily stored in the water storage tank. When both the hot water tap and the warm water tap are open, causing low water pressure in the electric water heater, a second booster pump can be activated to inject the temporarily stored pure water from the water storage tank into the electric water heater, thereby increasing the water pressure in the electric water heater, maintaining normal water pressure and efficiency, and improving the user experience.

[0015] 2. The water dispenser of this utility model has the advantage of stable water pressure, which can ensure normal water pressure and water output efficiency, and improve the user experience. Attached Figure Description

[0018] Figure 3 This is a schematic diagram of the water system in this utility model. Detailed Implementation

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 3As shown, the water system of this utility model includes: a filter module 1, an electric water tank 2, a water storage tank 3, and a heat exchanger 4. The inlet of the filter module 1 is connected to a water source via pipe A101, and a first booster pump 5 is connected in series on pipe A101. The pure water outlet of the filter module 1 is connected to the cold water inlet of the heat exchanger 4 via pipe B102. The cold water outlet of the heat exchanger 4 is connected to the inlet of the electric water tank 2. The first outlet of the electric water tank 2... The electric water tank 2 is connected to at least one hot water tap 6. Its second outlet is connected to the hot water inlet of the heat exchanger 4. The heat exchanger 4's warm water outlet is connected to at least one warm water tap 7. The filter module 1's pure water outlet is connected to the inlet of the storage tank 3 via a bypass pipe A103. The storage tank 3's outlet is connected to the cold water inlet of the heat exchanger 4 via a bypass pipe B104. A second booster pump 8 is connected in series on the bypass pipe B104. This invention, by setting up a storage tank, allows the pure water produced by the filter module to be temporarily stored in the tank when the electric water tank is full. When both the hot and warm water taps are open, causing low water pressure in the electric water tank, the second booster pump can be activated to inject the temporarily stored pure water into the electric water tank, thereby increasing the water pressure, maintaining normal water pressure and efficiency, and improving the user experience.

[0021] To ensure health, the water storage tank must be a sterile tank.

[0022] In this embodiment, a first check valve 10 is connected in series on the pipe B102. The first check valve 10 is used to prevent the water pressurized by the second booster pump 8 from flowing into the water storage tank or impacting the filter module (which can protect the filter module).

[0023] In this embodiment, a second check valve 9 is connected in series on the bypass pipe B104. The second check valve 9 is used to prevent water flowing from the pure water outlet of the filter module 1 from flowing into the water storage tank through the bypass pipe B.

[0024] In this embodiment, an activated carbon filter element 11 is connected in series on pipe B102 to improve the taste of drinking water.

[0025] In this embodiment, both the first booster pump and the second booster pump are connected to the controller.

[0026] In this embodiment, a pressure sensor 12 for detecting the water pressure inside the electric water tank 2 is provided on the electric water tank 2. The pressure sensor 12 is connected to the controller. When the pressure sensor 12 detects that the water pressure inside the electric water tank 2 is lower than a set value, it can feed back to the controller, which can then control the second booster pump to start, thereby increasing the water pressure inside the electric water tank 2. When the pressure sensor 12 detects that the water pressure inside the electric water tank 2 is higher than the set value, it can feed back to the controller, which can then control the first booster pump and / or the second booster pump to stop, to ensure safety.

[0027] In this embodiment, a solenoid valve 13 is installed on the bypass pipe A103, and an electronic float valve 14 is installed in the water storage tank 3 to control the start and stop of the solenoid valve 13. When the water in the water storage tank 3 is insufficient, the solenoid valve 13 can be opened according to the signal of the electronic float valve 14 to replenish the water storage tank.

[0028] In this embodiment, an overflow port 301 is provided at the top of the water storage tank 3. In order to prevent the water storage tank 3 from overflowing through the top opening when the electronic float valve 14 fails, excess water is discharged through the overflow port 301.

[0029] In this embodiment, the hot water tap 6 and the warm water tap 7 are sensor taps, which are convenient to use.

[0030] This embodiment features a water dispenser with a sterile water tank, dual water supply, and normal pressure water output. The water dispenser uses the water circuit system described above, which has the advantage of stable water pressure, ensuring normal water pressure and output efficiency, and improving user experience.

[0031] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
