Abstract

The microwave water heater is composed of a shell, a controller, a microwave generator, a waveguide, a wave-transmitting seal, and a heating chamber. The water in the water tank can enter the heating chamber through the shielding net covering the heating chamber and be heated by microwaves, while the microwaves cannot enter the water tank through the shielding net. Therefore, the microwaves will not cause harm to the user, and due to the rise and fall of heat, the water heated by the microwaves will rise, and the water with lower temperature in other parts of the water tank will be added to the heating chamber, and this cycle will be repeated until the water temperature reaches the preset requirement. The present invention can not only be used to heat water in an open environment, but also can be used to heat water on a water heater, and the shell of the water heater can be made of non-metallic materials, and there is no need to install a shielding device at the water inlet and outlet.

technical field

The invention relates to a microwave water heater, which belongs to the application technology of microwave in the field of water heating.

Background technique

In bathtubs, bathtubs, sinks, and other open environments, microwaves cannot be used to directly heat water therein. In addition, the application of microwaves on water heaters usually uses the water tank shell as an electromagnetic shielding seal, and a shielding device needs to be installed at the water inlet and outlet, and both need to be grounded, and the structure is relatively complicated. The water tank shell needs to be made of metal materials.

Therefore, it is necessary to find a microwave water heater, which can not only heat water in an open environment, but also can be applied to a water heater, so that the shell of the water heater can be made of non-metallic materials, and there is no need to install shielding at the water inlet and outlet device.

The object of the present invention is to provide a microwave water heater, which can not only heat water in an open environment, but also can be applied to a water heater, so that the shell of the water heater can be made of non-metallic materials, and there is no need for water inlet and outlet Install shielding.

The technical scheme of the present invention is: a kind of microwave water heater, is made up of housing 1, controller 2, microwave generator 3, waveguide 4, wave-transmitting sealing body 5, heating cavity 6, and housing 1 is made up of The water tank 11 of the water tank 11 is composed of the electrical appliance compartment 12 located below, and the controller 2, the microwave generator 3, and the waveguide 4 are sequentially installed in the electrical appliance compartment 12; the bottom wall or side wall of the water tank 11 has a wave-transparent hole, and the wave-transmissive sealing body 5 is placed on the wave-transmitting hole so that water cannot enter the waveguide 4 from the wave-transmitting hole. One end of the wave-transmitting hole is located in the electrical compartment 12 and is connected to the outlet of the waveguide 4. The heating chamber 6 is located in the water tank 11 and fixed on the wave-transmitting On the hole; the heating cavity 6 is a hollow cavity covered by a shielding net, and microwaves cannot radiate outward from the heating cavity 6; The water in the heating chamber 6 is heated.

The wave-transparent sealing body 5 is made of non-metallic materials.

The top opening of water tank 11.

Beneficial effect

1. The water in the water tank can enter the heating chamber through the shielding net covered on the heating chamber and be heated by microwaves, but the microwave cannot enter the water tank through the shielding net. Therefore, the microwave will not cause harm to the user, and due to heat rise and cold drop , the water heated by the microwave will rise, and the water with lower temperature in other parts of the water tank will be added to the heating cavity, and so on, until the water temperature reaches the preset requirements.

2. Not only can it be used to heat water in an open environment, but it can also be used to heat water on a water heater, and the shell of the water heater can be made of non-metallic materials, and there is no need to install shielding devices at the water inlet and outlet.

Fig. 1 is a schematic structural view of the present invention.

Detailed ways

As shown in Figure 1, a microwave water heater is composed of a housing 1, a controller 2, a microwave generator 3, a waveguide 4, a wave-transparent sealing body 5, and a heating chamber 6. The housing 1 is composed of a water tank 11 and The electrical appliance compartment 12 located below is composed of the controller 2, the microwave generator 3, and the waveguide 4, which are sequentially installed in the electrical appliance compartment 12; the bottom wall or the side wall of the water tank 11 has a wave-transparent hole, and the wave-transparent sealing body 5 is placed in the transparent On the wave hole, so that water cannot enter the wave guide 4 from the wave transparent hole, one end of the wave transparent hole located in the electrical compartment 12 is connected to the outlet end of the wave guide 4, and the heating chamber 6 is located in the water tank 11 and fixed on the wave transparent hole; The heating cavity 6 described above is a hollow cavity covered by a shielding net. Microwaves cannot radiate outward from the heating cavity 6; The water is heated.

The wave-transmissive sealing body 5 is made of non-metallic material, so that the microwave can pass through the wave-transmitting sealing body from the waveguide and enter into the heating chamber to heat the water in the heating chamber.

The upper opening of water tank 11 is so that put into the article that needs heating.

The heating cavity 6 is a hollow cavity covered by a shielding net. Water enters the heating chamber from the shielding net, and microwaves enter the heating chamber 6 through the wave-transparent sealing body 5 to heat the water in it. After the water temperature rises, according to the principle of heat rise and cool fall, the water with high temperature will rise, and the water tank will The water with low temperature in other parts of the water tank will flow into the heating chamber 6 to continue heating, and then rise after the temperature rises, and the water with low temperature in other parts of the water tank will flow into and be heated again. The purpose of heating water.

When the present invention is applied to the water heater, there is no need to install a shielding device at the water inlet and outlet. The shell of the water heater can be made of metal materials or non-metal materials, because the microwave has been installed outside the heating chamber 6 in the water tank. The shielding network is blocked.

When applied in an open environment, due to the small mesh of the shielding mesh, in daily use, human fingers or other body parts cannot enter the mesh, so it will not cause harm to the human body.

For safety reasons, a safety net can also be added on the outside of the shielding net.

With the microwave water heater of the present invention, the water in the water tank can enter the heating chamber through the shielding net covered on the heating chamber and be heated by microwaves, but the microwave cannot enter the water tank through the shielding net, so the microwave will not cause harm to the user. Injury, and due to heat rise and cold drop, the water heated by the microwave will rise, and the water with lower temperature in other parts of the water tank will be replenished into the heating chamber, and so on, until the water temperature reaches the preset requirements.

The microwave heating method is adopted, with low installed power, high efficiency, fast heating speed, clean and hygienic, and the water liquid is heated through the heating chamber, and the object in the liquid can also be heated.

The above-mentioned embodiments are only used to illustrate and explain the purpose of the present invention, rather than to limit the present invention. Those of ordinary skill in the art may make various changes or substitutions within the essential scope of the present invention, which shall also belong to the present invention. scope of protection for inventions.
