Description

Technical Field

[0001] The present invention belongs to the technical field of water heaters, and more specifically, relates to an instant water heater. Background Art

[0002] At present, water heaters on the market can be divided into float-type water heaters, boiling-type water heaters, step-type water heaters, and instant water heaters according to their structures.

[0003] For a float-type water heater, the water level in its water tank is controlled by a float. After hot water is output, the water level drops, the float follows and drops, the inlet valve opens, cold water is input, and the cold water and hot water are mixed to produce mixed water. The entire water tank is boiled again, and thousand-boiled water is repeatedly produced. For a boiling-type water heater, the water level in the water tank is controlled by two water level probes. First, a whole tank of cold water is injected, and then the heating tube is started. After boiling, when hot water is output to the lowest water level, a second tank of cold water is input again. The lower water level probe and the faucet are at the same position, and the water below the faucet cannot be completely output, and it will be mixed with the newly input cold water every time, producing mixed water, and thousand-boiled water is produced after long-term repeated heating. Both the float-type and boiling-type water heaters are provided with large water tanks, and after boiling, they need to be kept warm as a whole, consuming a large amount of electric energy. There is a mixture of hot water and cold water, resulting in the repeated boiling of thousand-boiled water, which affects human health when consumed. Moreover, the outer wall of the machine shell becomes overheated after being used for a period of time.

[0004] For a step-type water heater, water enters from the bottom layer and is heated step by step layer by layer until the water is boiled, which can improve the separation of cold and hot water, ensure a single boiling, and alleviate the generation of "yin-yang water". However, the water temperature can only reach 99 degrees and cannot boil. Due to the single-tank structure, cold and hot mixed water will also be generated when cold water is injected.

[0005] For the existing instant water heaters, cold water is quickly heated by a heating tube, there is no mixed water, and hot water is directly heated out. The heating coil is thin, the water flow rate is fast, and the water is not easily boiled. Moreover, the flowing water pipe is also a heating pipe, and scale is easily generated inside the pipe and it is not easy to clean. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] The embodiment of the present invention provides an instant water heater, as Figure 1As shown in the figure, it includes a heating device, and the heating device includes a first outer casing 11, an atomizing member 12 and a first heating member 13. An inlet 111 for inputting cold water is provided at the upper part of the first outer casing 11. An outlet 112 for outputting heated hot water is provided at the lower part of the first outer casing 11. Preferably, the outlet 112 is arranged at the bottom end of the first outer casing 11, so that the heated hot water can completely flow out from the outlet 112, without staying in the first outer casing, and thus cold and hot water will not be mixed, and repeated heating to form thousand-boiled water will not occur. Both the atomizing member 12 and the first heating member 13 are located inside the first outer casing 11. The atomizing member 12 is arranged at the inlet 111. Among them, the atomizing member 12 is connected to the inlet 111 and is used to atomize the cold water input from the inlet 111 into tiny water particles and suspend them in the first outer casing 11. For example, the atomizing member 12 is an atomizing nozzle. The first heating member 13 is used to heat the water in the first outer casing 11. For example, the first heating member 13 can be an electric heating rod, which uses electric energy to generate heat energy to heat water.

[0024] For the instant water heater according to the embodiment of the present invention, cold water is input from the inlet 111, atomized into ultra-fine water particles by the atomizing member 12 at the inlet and diffused into the first outer casing 11. The first heating member 13 heats the water, and the heated atomized water gathers at the outlet 112 and flows out, realizing instant use. By atomizing the cold water through the atomizing member 12 to form ultra-fine particles, the heating area of the water is increased, the heating efficiency is improved, the heating is sufficient, and the heating time is shortened. At the same time, no energy is required for heat preservation, the mixing of cold and hot water in the water storage tank is avoided, and thousand-boiled water will not be generated.

[0025] Preferably, the first heating member 13 is located at the lower part inside the first outer casing 11. The upper half of the cavity between the first heating member 13 and the first outer casing 11 is large, which is beneficial to the diffusion of the atomized ultra-fine water particles and not easy to aggregate. All the ultra-fine water particles can be quickly heated, improving the heating efficiency and shortening the heating time. The ultra-fine water particles fall to the lower part of the first outer casing 11 under the action of gravity, and part of them will drip onto the first heating member 13 and be heated again, thereby further improving the heating effect. Further, the distance between the first heating member 13 and the lower inner wall of the first outer casing 11 is small, so that most of the ultra-fine water particles can fall on the first heating member and be further heated, making the heating sufficient.

[0026] As a preference, the first heating member 13 is in a spindle shape. The atomized ultra-fine water particles fall on the first heating member 13 under the action of gravity. The first heating member 13 is in a spindle shape, and the water falling on the first heating member 13 flows down along the outer surface of the first heating member 13 to the outlet, making the heating more sufficient and improving the heating effect.

[0027] Preferably, the instant water heater of this embodiment further includes a second heating device, which is connected to the heating device. The second heating device is provided with a hot water inlet 211 and a hot water outlet 212. The hot water inlet 211 communicates with the water outlet 112 of the first outer casing of the heating device. After the heating device heats the water, the hot water is input into the second heating device for further heating, making up for the deficiency of the heating device and ensuring the heating effect, so as to meet the usage requirements of direct drinking water or high-temperature water.

[0028] Furthermore, as Figure 2 shown, the second heating device has a spiral tubular structure. The hot water inlet 211 is located at the upper end of the second heating device, and the hot water outlet 212 is located at the lower end of the second heating device. The spiral tubular structure, compared with the straight tubular structure, lengthens the flow path between the hot water inlet 211 and the hot water outlet 212, enabling the water to be fully heated in the second heating device to output high-temperature water. The hot water outlet 212 is located at the lower end of the second device, allowing the water in the second heating device to completely flow out from the hot water outlet 212 without staying in the second heating device, preventing the mixing of cold and hot water and the generation of repeatedly boiled water.

[0029] Preferably, a solenoid valve and a temperature controller 3 are provided at the hot water outlet 212. The temperature controller 3 is connected to the solenoid valve. The solenoid valve is used to control the flow of the pipeline at the hot water outlet. The temperature controller 3 is used to measure the water temperature at the hot water outlet and control the solenoid valve to open when the water temperature reaches the preset temperature, outputting hot water at the preset temperature.

[0030] Preferably, as Figure 3As shown in the figure, the second heating device includes a second outer casing 21 and a second heating element 22 disposed within the second outer casing 21. The hot water inlet 211 and the hot water outlet 212 are provided on the second outer casing 21. The second heating element 22 includes a second heating housing 221 and a second heating inner tank 222, and the second heating inner tank 222 is disposed within the second heating housing 221. The first heating element 13 includes a first heating housing 131 and a first heating inner tank 132, and the first heating inner tank 132 is filled within the first heating housing 131. The first outer casing 11 and the second outer casing 21 are in communication, the first heating housing 131 and the second heating housing 221 are in communication, and the first heating inner tank 132 and the second heating inner tank 222 are connected. The first outer casing 11 and the second outer casing 21 are directly in communication, and the first heating housing 131 and the second heating housing 221 are directly in communication, such that the first heating chamber and the second heating chamber are directly in communication, and water flows from the heating device to the second heating device without passing through other structures, preventing the temperature of the water from dropping during transmission and ensuring the heating effect. To simplify the manufacturing process, preferably, the first outer casing 11 and the second outer casing 21 are integrally formed, and the first heating housing 131 and the second heating housing 221 are integrally formed.

[0031] Preferably, the instant water heater of the present embodiment further includes an energy supply device 4, and the energy supply device 4 is connected to the second heating inner tank 222 through a heat transfer member 5. The energy supply device 4 may be a device that provides electrical energy, and the second heating inner tank 222 and the first heating inner tank 132 convert electrical energy into heat energy to heat water. Preferably, the energy supply device 4 is a device that provides heat energy converted from solar energy, such as a solar heat collection device. The energy supply device 4 provides heat energy to the second heating inner tank 222, and the second heating inner tank 222 then transfers the heat energy to the first heating inner tank 132. The first heating inner tank 132 and the second heating inner tank 222 heat the water. Using solar energy to heat water makes full use of natural energy and saves electrical energy.

[0032] Furthermore, the second heating inner tank 222 is a heat pipe; the first heating inner tank 132 has a mesh structure and is made of a heat pipe. In this embodiment, heat pipes are used to transfer heat energy for water heating, with small heat loss, fast heat conduction speed, and high heating efficiency.

[0033] Furthermore, the heat transfer member 5 is a heat pipe, and a heat insulation layer 51 is provided on the outer surface of the heat transfer member 5. The heat energy generated by the energy supply device is transferred to the second heating inner tank and the first heating inner tank through a heat pipe with a heat insulation layer on its outer surface, reducing heat loss during the transfer process, such that the vast majority of the heat energy can be used for water heating and the heating efficiency is improved.

[0034] Preferably, the first outer housing 11, the second outer housing 21, the first heating housing 131 and the second heating housing 221 are all made of crystal. Crystal has better heat conduction performance than glass, is heat-resistant, has good chemical stability, and will not change color after long-term use. Compared with polymer and metal materials, crystal heating will not release carcinogenic substances and is safer and healthier.

[0035] The working process of the preferred embodiment of the present invention is as follows: Open the hot water outlet 212 and at the same time open the water inlet 111. Cold water enters the atomizing member 12 through the water inlet 111 and is atomized into ultra-fine water particles of 1 μm to 5 μm and diffuses into the first outer housing 11. The heat of the first heating inner tank 132 is transferred to the air in the first outer housing 11 through the first heating housing 131 to heat the atomized ultra-fine water particles. The atomized water falls downward under the action of gravity, and most of it falls onto the first heating member 13 and flows downward along the outer surface of the first heating member 13, and is heated by the first heating member 13 again. Finally, all the water converges at the bottom of the first outer housing 11 and flows from the water outlet 112 through the hot water inlet 211 into the space between the second outer housing 21 and the second heating housing 221 of the second heating device. After further heating by the second heating member 22, when the water temperature at the hot water outlet 212 reaches the preset temperature, the temperature controller 3 controls the water valve to open, and the hot water flows out from the hot water outlet 212.

Those skilled in the art should understand that the present invention is not limited by the above specific embodiments, and the above specific embodiments and the descriptions in the specification are only for further explaining the principles of the present invention.
