Description

Technical Field

[0001] This utility model relates to the field of drinking water supply technology, specifically a hot water module. Background Technology

[0002] Currently, traditional water dispensers and hot water faucets mainly rely on instant heating elements to quickly heat water when using high-temperature water. Because of the large temperature difference between high-temperature water and room-temperature water, instant heating elements can only meet the demand for small-flow high-temperature water and large-flow low-temperature hot water, but cannot meet the demand for large-flow high-temperature hot water. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention provides a hot water module to solve the above-mentioned technical problems.

[0004] To achieve the aforementioned objectives, the present invention provides the following technical solution:

[0005] A hot water module includes a water tank, a water pump, an inlet solenoid valve, an instant heating element, a water circuit switching valve, a normal temperature water inlet, and a temperature-adjustable water outlet. The water pump includes a first water pump and a second water pump. One end of the inlet solenoid valve is connected to the normal temperature water inlet, and the other end is connected to the temperature-adjustable water outlet. The normal temperature water inlet is connected to the inlet of the first water pump, the outlet of the first water pump is connected to the inlet of the instant heating element, the outlet of the instant heating element is connected to the inlet of the water circuit switching valve, one outlet of the water circuit switching valve is connected to the water tank, and the other end is connected to the temperature-adjustable water outlet. The inlet of the second water pump is connected to the water tank, and the outlet of the second water pump is connected to the inlet of the instant heating element.

[0006] Preferably, a flow meter is installed between the outlet of the second water pump and the inlet of the instantaneous heating element, the outlet of the second water pump is connected to the inlet of the flow meter, and the outlet of the flow meter is connected to the inlet of the instantaneous heating element.

[0007] Preferably, a flow meter is provided between the outlet of the first water pump and the inlet of the instantaneous heating element, the outlet of the first water pump is connected to the inlet of the flow meter, and the outlet of the flow meter is connected to the inlet of the instantaneous heating element.

[0008] Preferably, both the first and second water pumps are diaphragm water pumps.

[0009] Preferably, the instant heating element is an instant integrated heating element.

[0010] Preferably, the water tank is an energy storage water tank.

[0011] Preferably, the inlet of the second water pump is connected to the water tank at the bottom of the water tank.

[0012] Preferably, the water tank is provided with an overflow port at the top.

[0013] The working principle of the hot water module provided by this utility model is as follows:

[0014] 1. Normal temperature water enters through the normal temperature inlet. When the first water pump is off, the inlet solenoid valve is opened, and normal temperature water flows directly out through the temperature-adjustable outlet. At this time, the module provides normal temperature water to the water dispenser or faucet.

[0015] II. When the inlet solenoid valve is closed and the first water pump is working, room temperature water enters the instantaneous heating element and is heated before entering the water circuit switching valve. When the water circuit switching valve connects the water circuit to the temperature-adjustable outlet, the hot water heated by the instantaneous heating element flows directly out through the temperature-adjustable outlet. This can meet the needs of small-flow high-temperature water output and large-flow low-temperature hot water output. When the water circuit switching valve connects the water circuit to the water tank, the hot water heated by the instantaneous heating element enters the water tank for storage. After the water tank stores high-temperature hot water, the first water pump stops working, and the second diaphragm water pump starts working. The water circuit switching valve connects the water circuit to the temperature-adjustable outlet. The hot water in the water tank enters the instantaneous heating element through the second diaphragm water pump and is heated before flowing out through the temperature-adjustable outlet. Because the high-temperature hot water in the water tank is hot water that has been heated by the instantaneous heating element and stored for a short time, its temperature is very high after being heated again by the instantaneous heating element, which can meet the needs of large-flow high-temperature hot water output.

[0017] Marked in the attached diagram:

[0018] 1. First water pump; 2. Second water pump; 3. Water circuit switching valve; 4. Instantaneous heating element; 5. Inlet solenoid valve; 6. Flow meter; 7. Water tank; 8. Normal temperature inlet; 9. Temperature-adjustable outlet. Detailed Implementation

[0019] 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.

[0020] For examples, please refer to Figure 1This application provides a hot water module, including a water tank 7, a water pump, an inlet solenoid valve 5, an instant heating element 4, a water circuit switching valve 3, a normal temperature water inlet 8, and a temperature-adjustable water outlet 9. The water pump includes a first water pump 1 and a second water pump 2. One end of the inlet solenoid valve is connected to the normal temperature water inlet, and the other end is connected to the temperature-adjustable water outlet. The normal temperature water inlet is connected to the inlet of the first water pump, the outlet of the first water pump is connected to the inlet of the instant heating element, the outlet of the instant heating element is connected to the inlet of the water circuit switching valve, one outlet of the water circuit switching valve is connected to the water tank, and the other end is connected to the temperature-adjustable water outlet. The inlet of the second water pump is connected to the water tank, and the outlet of the second water pump is connected to the inlet of the instant heating element. In this embodiment, both the first and second water pumps are preferably diaphragm water pumps, the instantaneous heating element is preferably an instantaneous integrated heating element, the water tank can be an existing water tank, and heating elements such as electric heating tubes and heat exchange tubes can also be installed in the water tank, preferably an energy storage water tank.

[0021] The working principle of the above-mentioned hot water module is as follows:

[0022] 1. Normal temperature water enters through the normal temperature inlet. When the first water pump is off, the inlet solenoid valve is opened, and normal temperature water flows directly out through the temperature-adjustable outlet. At this time, the module provides normal temperature water to the water dispenser or faucet.

[0023] II. When the inlet solenoid valve is closed and the first water pump is working, room temperature water enters the instantaneous heating element and is heated before entering the water circuit switching valve. When the water circuit switching valve connects the water circuit to the temperature-adjustable outlet, the hot water heated by the instantaneous heating element flows directly out through the temperature-adjustable outlet. This can meet the needs of small-flow high-temperature water output and large-flow low-temperature hot water output. When the water circuit switching valve connects the water circuit to the water tank, the hot water heated by the instantaneous heating element enters the water tank for storage. After the water tank stores high-temperature hot water, the first water pump stops working, and the second diaphragm water pump starts working. The water circuit switching valve connects the water circuit to the temperature-adjustable outlet. The hot water in the water tank enters the instantaneous heating element through the second diaphragm water pump and is heated before flowing out through the temperature-adjustable outlet. Because the high-temperature hot water in the water tank is hot water that has been heated by the instantaneous heating element and stored for a short time, its temperature is very high after being heated again by the instantaneous heating element, which can meet the needs of large-flow high-temperature hot water output.

[0024] In a preferred embodiment, a flow meter 6 is installed between the outlet of the second water pump and the inlet of the instantaneous heating element. The outlet of the second water pump is connected to the inlet of the flow meter, and the outlet of the flow meter is connected to the inlet of the instantaneous heating element. Alternatively, a flow meter 6 can also be installed between the outlet of the first water pump and the inlet of the instantaneous heating element, with the outlet of the first water pump connected to the inlet of the flow meter and the outlet of the flow meter connected to the inlet of the instantaneous heating element. The first and second water pumps can be connected to a single flow meter or to separate flow meters, as is well known to those skilled in the art and will not be elaborated further here.

[0025] In actual manufacturing, the inlet of the second water pump can be connected to the bottom of the water tank, while the water circuit switching valve can be connected to the top of the water tank. Of course, an overflow port can also be provided at the top of the water tank, as is well known to those skilled in the art, and will not be elaborated upon here.
