The gas water heater heats by using burning natural gas, but the waste gas generated by burning the natural gas has certain toxicity, and the smoke poisoning caused by unsmooth smoke emission occurs. The heat pump water heater heats by utilizing heat in the environment, but when the ambient temperature is lower than 5 ℃, the heating capacity of the heat pump water heater is greatly reduced, and particularly in northern winter with lower temperature, the heating effect is poor. The electric water heater is less affected by the environment, does not need to discharge smoke, and therefore can stably output hot water in different environments, but at present, the electric water heater usually adopts a water-in-water or water-in-water type to heat water, and although the electric water heater is provided with devices such as a leakage-proof wall and the like, leakage accidents still occur every year. The electromagnetic water heater heats water by utilizing the variable-frequency electromagnetic heating effect, can effectively realize water-electricity separation and is safe, but the electromagnetic water heater still has the problems of strong electromagnetic radiation and poor heat dissipation because the electromagnetic heating device has certain structural defects.

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, the heating apparatus of the embodiment of the present invention includes an electromagnetic heating device 100 for heating water. Next, the structure of the electromagnetic heating device 100 in the present application will be described by taking a heating apparatus as a water heater as an example. The following examples are given by way of illustration only and are not intended to limit the scope of the present application. It is understood that in other embodiments, the heating device may also be embodied as other appliances equipped with the electromagnetic heating apparatus 100, and is not limited herein.
The electromagnetic heating apparatus 100 includes a heat radiation housing 10, a heating assembly 20, a heating coil 30, and a heat radiation medium 40. The heat dissipation housing 10 forms a heat dissipation space, the heating assembly 20 forms a water flow channel, and includes an inlet section 21, a heating section 23, and an outlet section 25, which are connected in sequence, wherein the heating section 23 is located in the heat dissipation space, and the inlet section 21 and the outlet section 25 extend out of the heat dissipation space. The heating coil 30 is partially accommodated in the heat dissipation space and surrounds the heating section 23, and the heat dissipation medium 40 is filled in the heat dissipation space. The heating coil 30 may generate a magnetic field, and the heating assembly 20 may be heated by the magnetic field to heat the water in the water flow channel.
the electromagnetic heating device 100 utilizes the electromagnetic heating effect, the energized heating coil 30 generates a magnetic field, and the heating assembly 20 induces the magnetic field to heat water in the heating water channel. Since the heating element 20 and the heating coil 30 are both accommodated in the heat radiation housing 10 filled with the heat radiation medium 40, the electromagnetic radiation emitted from the heating coil 30 is reduced by the heat radiation medium 40. Moreover, since the heat dissipation medium 40 near the heating coil 30 absorbs heat and flows in the direction of the heat dissipation housing 10 to form circulating heat dissipation, the safety hazard caused by the excessively high operating temperature of the electromagnetic heating device 100 is avoided, and when the power of the heating coil 30 is increased, the volume of the heating coil 30 does not need to be additionally increased in order to increase the heat dissipation performance of the heating coil 30, thereby being beneficial to the miniaturization development of the heating equipment provided with the electromagnetic heating device 100.
Referring to fig. 1, the heat dissipating housing 10 is a hollow housing structure, a heat dissipating space is formed inside the heat dissipating housing 10, and a through hole for communicating the heat dissipating space with the external environment is formed on a side wall of the heat dissipating housing 10 to allow the heating element 20 and the heating coil 30 to pass through.
The heat dissipation medium 40 completely fills the remaining space inside the heat dissipation housing 10 except for the heating element 20 and the heating coil 30, so as to completely immerse the heating element 20 and the heating coil 30, and while effectively isolating the electromagnetic radiation emitted by the heating coil 30, the heat generated by the heating coil 30 and the heating element 20 can be dissipated through the heat dissipation housing 10 by circulating in the heat dissipation housing 10, thereby effectively controlling the temperature of the electromagnetic heating apparatus 100.
In some embodiments, the heat dissipation medium 40 is heat dissipation oil, and the main components of the heat dissipation oil are alkanes, naphthenic saturated hydrocarbons, aromatic unsaturated hydrocarbons, and other compounds, which have good stability, thermal conductivity, and electromagnetic isolation. It is to be understood that the substance forming the heat dissipation medium 40 is not limited thereto, and may be selected as needed.
the heating assembly 20 has a hollow tubular structure, thereby forming a water flow passage allowing water to flow therethrough, and cold water enters the heating section 23 from the inlet section and is discharged through the outlet section 25 after being warmed in the heating section 23. The heating assembly 20 is formed of a heat conductive material resistant to high temperature, and thus the heating assembly 20 may be warmed up by the magnetic field to heat water located in the water flow passage of the heating section 23 based on the electromagnetic heating effect. It is understood that the shape and material of the heating assembly 20 are not limited and may be set as desired.
The electromagnetic heating apparatus 100 further includes a driving unit 60 and a control unit 70 located outside the heat radiating housing 10, the control unit 70 is connected to the driving unit 60 in communication, the driving unit 60 is electrically connected to the heating coil 30, and the control unit 70 may control the driving unit 60 to output a high frequency current to flow through the heating coil 30, thereby causing the heating coil 30 to generate a magnetic field.
in some embodiments, the electromagnetic heating apparatus 100 further includes an insulation structure 50, and the insulation structure 50 is filled between the heating assembly 20 and the heating coil 30, thereby achieving water and electricity isolation. Specifically, in one embodiment, the insulation structure 50 is wrapped around the heating section 23 of the heating assembly 20, and the heating coil 30 is circumferentially wound around the insulation structure 50 from one end to the other end of the insulation structure 50. In this way, due to the arrangement of the insulation structure 50, even if the heating assembly 20 has a water leakage phenomenon, the leaked water cannot contact the heating coil 30; similarly, when the heating coil 30 has an electric leakage phenomenon, the current cannot be transmitted to the water in the heating assembly 20, so as to avoid harming the personal safety of the user. More specifically, the insulating structure 50 is a columnar structure formed of a ceramic insulating material. It is understood that the material and shape of the insulating structure 50 are not limited thereto, and may be selected as desired.
In some embodiments, electromagnetic heating apparatus 100 further includes a flow sensing unit 80 and a temperature sensing unit 90, each communicatively coupled to control unit 70. The flow sensing unit 80 is disposed at the inlet section 21 of the heating assembly 20, and is configured to detect the water flow of the inlet section 21 in real time and send the water flow to the control unit 70. The temperature sensing unit 90 is disposed at the outlet section 25 of the heating assembly 20, and is used for detecting the water temperature of the heating section 23 in real time and transmitting the water temperature to the control unit 70. The control unit 70 may compare the acquired water temperature with a preset water temperature, and automatically adjust the operating state of the driving unit 60 according to the water temperature difference and the water flow rate, thereby adjusting the heating power of the heating coil 30, thereby achieving automatic control of the water temperature and achieving the requirement of constant water temperature.
Specifically, in an embodiment, the flow sensing unit 80 includes a hall element, and the hall element can output different electric signals to the control unit 70 according to the magnitude of the water flow in the water flow channel, and when the water flow in the water flow channel is larger, the electric signal contains a larger number of pulses, and the control unit 70 can accurately obtain the water flow of the inlet section according to the number of pulses in the obtained electric signal, so as to accurately adjust the operating state of the heating coil 30 according to the water flow.
The electromagnetic heating device 100 and the heating equipment provided with the same output hot water in an electromagnetic heating mode, so that compared with the traditional electric water heater, effective water and electricity isolation is realized, and the safety and reliability are higher; compared with the traditional heat pump water heater and the solar water heater, the solar water heater can stably heat without being influenced by the environmental temperature; compared with the traditional gas water heater, the gas water heater does not need to discharge toxic and harmful gas. Moreover, since the heating assembly 20 and the heating coil 30 are both immersed in the heat dissipation medium 40, self-cooling is achieved while electromagnetic radiation is effectively reduced, and thus, it is not necessary to increase the volume of the heating coil 30 in order to increase the heat dissipation efficiency of the heating coil 30 while increasing the power of the heating coil 30, thereby contributing to miniaturization of the heating apparatus. In addition, since the flow sensing unit 80 capable of accurately detecting the flow rate of water and the temperature sensing unit 90 capable of detecting the temperature of water are adopted, the heating power of the heating coil 30 can be adjusted according to the real-time flow rate of water and the temperature of water, and rapid constant temperature can be realized.
the technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
