Water-cooling silent frequency-variable microwave oven

Abstract

The invention discloses a water-cooling silent frequency-variable microwave oven, and relates to the field of microwave ovens. The water-cooling silent frequency-variable microwave oven comprises a microwave oven body, an oven body outer cover and a magnetron installation cavity formed by the right side of the microwave oven body and the oven body outer cover, wherein a magnetron is installed in the magnetron installation cavity; the positive pole of the magnetron is sleeved with a water tank body with an annular water tank inside; the annular water tank surrounds the positive pole of the magnetron; the outer wall of the water tank body is provided with a water tank water inlet connector and a water tank water outlet connector communicated with the annular water tank; a water storage box is further arranged in the magnetron installation cavity and provided with a water storage box water inlet connector and a water storage box water outlet connector; the water tank water inlet connector is connected with the water storage box water outlet connector through a water pipe; the water tank water outlet connector is connected with the water storage box water inlet connector through a water pipe; a water pump is connected between the water tank water inlet connector and the water storage box water outlet connector in series. According to the water-cooling silent frequency-variable microwave oven, a large amount of heat generated in the work process can be cooled, the problem of noise is resolved, and the purpose of silence is realized.

Description

technical field [0001] The invention relates to the field of microwave ovens, in particular to a water-cooled silent frequency conversion microwave oven. Background technique [0002] Microwaves are electromagnetic waves. A microwave oven is composed of a power supply, a magnetron, a control circuit, and a cooking cavity. The power supply provides a high voltage of about 4000 volts to the magnetron. Under the excitation of the power supply, the magnetron continuously generates microwaves, and then couples into the cooking cavity through the waveguide system. Near the entrance of the cooking cavity, there is a rotatable stirrer, because the stirrer is a fan-shaped metal, which can reflect the microwave in all directions after rotating, so it can evenly distribute the microwave energy in the cooking cavity, thus Reheat food. [0003] The core component of the microwave oven is the magnetron. The magnetron emits microwaves to heat food. When it is working, the central tube c...

Problems solved by technology

Apparently, the above solution only noticed that water cooling can replace air cooling, but did not pay attention to the effect of water cooling on reducing noise; on the other hand, part of the water pipe is covered with fins, and the cost of fins is very high, so it is not practical enough , and the water pipe is wound outside the anode, the effective contact area between the anode and the water pipe is small, so it cannot transfer heat well
