Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and in particular to an instantaneous universal water heater. Background Technology

[0002] Currently, there are two main types of electric water heaters widely used by people. One type uses heating elements made of resistance wire or other heating elements that are directly immersed in water for heating. However, due to insulation aging, material problems, or manufacturing defects, leakage is prone to occur, causing safety accidents and electric shocks. The other type is electromagnetic heating water heaters, which use electromagnetic fields to generate eddy currents to heat the water in the water channel until a certain temperature is reached before use. Because a fixed amount of water is heated, a certain heating time is required before use. While convenient, the amount of water used each time is uncertain, which can easily lead to waste or water shortage. In view of this, researchers in this field have designed an instantaneous universal water heater. Utility Model Content

A water inlet channel is disposed between the heating element and the outer water cylinder. A water outlet channel communicating with the water inlet channel is disposed within the heating element. A water inlet is disposed at the bottom of the water inlet channel, a hot water inlet communicating with the water inlet channel is disposed at the top of the water outlet channel, and a water outlet is disposed at the bottom of the water outlet channel.

[0005] As can be seen from the above scheme, the energizing body is set on the outer wall of the outer water cylinder to heat the heating element through electromagnetic induction. The water inlet channel is used to allow water to enter from the outside of the heating element, and the water outlet channel is used to allow water to exit from the inside of the heating tube. This utility model separates the water inlet and outlet channels and the heating element from the energizing body, achieving the purpose of separating energization and heating. At the same time, the water flows into and out of the heating element and comes into contact with the outer and inner tube walls of the heating element respectively, increasing the heating area, improving the heat conduction effect, and reducing heat radiation loss by keeping the outside cool and the inside hot, thus achieving the effect of energy saving and consumption reduction.

[0006] The bottom of the outer water cylinder is connected to a connecting pipe seat, and a water inlet is provided on the side of the connecting pipe seat. A water outlet connector is connected to the bottom of the connecting pipe seat via a water outlet. A limiting groove adapted to the heating element is provided inside the connecting pipe seat, and a temperature probe is inserted into the water outlet via a limiting socket. Therefore, the limiting groove is used to limit the bottom of the heating element, the water inlet is used to allow water to enter the water inlet channel, the water outlet connector is used to connect to the water outlet to achieve hot water output, and the temperature probe is used to detect the water temperature at the water outlet.

[0007] The hot water tank is equipped with a water pump and a regulating valve seat. The output port of the water pump is connected to the regulating valve seat, and the input port of the water pump is connected to an inlet pipe connector. The regulating valve seat is connected to the inlet. Therefore, the water pump is used to pump water into the heating device.

[0008] The energizing element includes a conductor coil wound around the outer wall of the outer water cylinder, and the conductor coil is electrically connected to the control board inside the hot water tank. Therefore, the conductor coil is used to generate a high-frequency electromagnetic field after being energized, thereby heating the heating element.

[0009] A thermally conductive filler is provided between the conductor coils.

[0010] An insulator is provided on the outer wall of the conductor coil.

[0011] The outer water tank is made of thermally conductive plastic.

[0020] like Figures 1 to 5 As shown, this utility model is an instantaneous universal water heater, including a hot water tank 1 and a heating device disposed in the hot water tank 1. The heating device includes an outer water cylinder 2, a heating element 3, and an electric conductor. The outer water cylinder 2 is sleeved on the outside of the heating element 3. The electric conductor is disposed on the outer wall of the outer water cylinder 2. A water inlet channel 5 is disposed between the heating element 3 and the outer water cylinder 2. A water outlet channel 6 communicating with the water inlet channel 5 is disposed inside the heating element 3. A water inlet 51 is disposed at the bottom of the water inlet channel 5. A hot water inlet 61 communicating with the water inlet channel 5 is disposed at the top of the water outlet channel 6. A water outlet 62 is disposed at the bottom of the water outlet channel 6. In this embodiment, the heating element 3 has a thin wall. The hot water tank 1 includes a front shell and a rear shell detachably connected to the front shell. A limiting post is provided on the rear shell, and a limiting hole adapted to the limiting post is provided on the outer wall of the outer water cylinder 2. The limiting post is inserted into the limiting hole, thereby achieving the limiting and fixing of the outer water cylinder 2 within the hot water tank 1. The power-carrying wire is outside the insulated plastic outer water cylinder 2, and water flows inside the insulated tube. The heating element 3 is not connected to a power-carrying wire. This ensures safe use.

[0021] The bottom of the outer water cylinder 2 is connected to a connecting pipe seat 9. A water inlet 91 is provided on the side of the connecting pipe seat 9. A water outlet connector 11 is connected to the bottom of the connecting pipe seat 9 through a water outlet 92. A limiting groove 93 adapted to the heating element 3 is provided inside the connecting pipe seat 9. A temperature probe 12 is inserted into the water outlet 62 through a limiting socket 94.

[0022] The hot water tank 1 is equipped with a water pump 7 and a regulating valve seat 8. The output port of the water pump 7 is connected to the regulating valve seat 8, and the input port of the water pump 7 is connected to an inlet pipe connector 10. The regulating valve seat 8 is connected to the inlet 51. In this embodiment, the inlet pipe connector 10 and the outlet pipe connector 11 extend out of the hot water tank 1.

[0023] The energizing element includes a conductor coil 41 wound around the outer wall of the outer water tank 2, and the conductor coil 41 is electrically connected to the control board 13 inside the hot water tank 1.

[0024] Thermally conductive filler 43 is provided between the conductor coils 41. An insulator 14 is provided on the outer wall of the conductor coils 41. The outer water cylinder 2 is made of thermally conductive plastic, which facilitates the absorption of heat from the energized body when the water flows through the water inlet channel 5, thereby improving heat utilization and cooling the energized body. The heating element 3 is a tubular conductor.

[0025] The outer wall of the hot water tank 1 is provided with a display screen 15 and operation buttons 16. The display screen 15, operation buttons 16 and temperature probe 12 are electrically connected to the control board.

[0026] The working process of this utility model is as follows: the water pump 7 pumps cold water from the water pipe into the outer water cylinder 2. The conductor coil 41 is energized to heat the heating element 3. The cold water flows upward into the inlet channel 5, and when it flows in, it contacts the outer pipe wall of the heating element 3 to heat the water. The water flows upward from the hot water inlet 61 into the outlet channel 6, and when it flows downward, it contacts the inner pipe wall of the heating element 3. By the water flowing in and out, heat is transferred to the outer and inner pipe walls of the heating element, respectively, increasing the heating area, improving the heat conduction effect, and reducing heat radiation loss by keeping the outside cold and the inside hot. The heated water flows from the outlet 62 through the connecting pipe seat 9 and then out of the outlet pipe joint 11 to the water-using end.
