Abstract
A magnetron for microwave oven is composed of casing, antenna, anode, magnet and shielding box, and the cooling evaporating cavity between the first and the second magnets. The cooling vaporization cavity is a hollow circular ring, the inner wall of the cooling vaporization cavity is in contact with the surface of the anode, and the outer wall of the cooling vaporization cavity is provided with a water inlet and a steam outlet. The magnetron of the invention is provided with a cooling vaporization cavity outside the anode, and a dripping pump pumps water into the cavity to cool the anode in a water cooling mode. Because the cooling water enters the cavity in a water drop mode, the water drops can generate water vapor when the temperature of the anode is reduced; the steam enters into the cavity of the microwave oven through the steam outlet of the cooling vaporization chamber and heats the food in a steam cooking manner. The invention not only improves the cooling effect of the magnetron, prolongs the service life of the magnetron, but also saves energy and improves the energy efficiency grade of the microwave oven.
Description
Technical field
The present invention relates to a kind of magnetron, the water-cooled magnetron that particularly a kind of micro-wave oven is used.
Background technology
The power supply connecting device of magnetron for microwave oven comprises high-tension transformer, high-voltage capacitance etc.The energy conversion efficiency of magnetron is about 70%, promptly 70% of magnetron institute consumed power converts microwave energy into, and all the other electric energy of 30% will convert heat to.These heats are mainly produced by the anode of magnetron.The voltage of general anode of magnetron is 3～4kV high pressure; Anode is worked under high pressure conditions and can be produced great amount of heat; These heats must in time distribute; To avoid because magnetron is worked for a long time the situation that the magnetron unstable properties that is caused, life-span reduce under the excessive temperature environment.So, magnetron is cooled, be to ensure the necessary process of its operate as normal.
At present; Generally adopt air-cooled mode that magnetron is cooled, its structure is that fin is housed outside vacuum tube, with the cooling of dispelling the heat of the mode of electric fan blowing; Though this mode can guarantee the operate as normal of magnetron, this heat energy of 30% has but wasted.In addition, the shortcoming of wind-cooling heat dissipating is that radiating effect is not good, and temperature of anode is still too high, so can not guarantee the stability that magnetron works long hours.The long-term temperature of anode is too high, also causes the performance of magnetron to descend the lost of life.Therefore, be necessary to do further improvement.
Summary of the invention
The object of the invention aims to provide a kind of can fully the cooling, and the magnetron that the micro-wave oven that can utilize the steam that produces in the cooling procedure that food is heated is again used is to overcome the weak point of prior art.
The magnetron of using by a kind of micro-wave oven of this purpose design; Comprise shell, antenna, anode, magnet and shielding box; Its architectural feature is that the male or female outer shroud of magnetron is with the cooling vaporization chamber, and the cooling vaporization chamber is the annulus of hollow, and its outer wall is provided with water inlet and steam (vapor) outlet.
The internal diameter of said cooling vaporization chamber and the external diameter of male or female adapt, and the inwall of cooling vaporization chamber contacts with the surface of male or female.
The upper end of said anode is provided with first magnet, and the lower end is provided with second magnet, and the cooling vaporization chamber is fixed between first magnet and second magnet.
Said water inlet and steam (vapor) outlet are symmetricly set on the both sides of cooling vaporization chamber, and water inlet is connected with the pump that drips, and steam (vapor) outlet is connected with the furnace chamber of micro-wave oven.
The drip nozzle of the said pump that drips is connected with water inlet, and the shape and the water inlet of drip nozzle adapt, so that water inlet is sealed.
Said steam (vapor) outlet is connected with the furnace chamber of micro-wave oven through steam pipe.
The top of said cooling vaporization chamber is provided with screw, and the cooling vaporization chamber is fixed through screw, screw and shell.
Said steam pipe is the low rubber tube of thermal conductivity factor.
Magnetron of the present invention is with the cooling vaporization chamber at the outer ring of anode, and the pump that drips pumps into water in the chamber, utilizes the mode antianode of water-cooled to lower the temperature.Because cooling water gets in the chamber with the mode of water droplet, water droplet just can generate water vapour in the antianode cooling; Steam gets in the furnace chamber of micro-wave oven through the steam (vapor) outlet of cooling vaporization chamber, and with the mode heat food of steam cooking.The present invention has not only promoted the cooling effect of magnetron, has prolonged the service life of magnetron, has also practiced thrift the energy, has promoted the efficiency grade of micro-wave oven.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Referring to Fig. 1-Figure 10, the magnetron that a kind of micro-wave oven is used comprises shell 1, antenna 2, anode 3, magnet 4 and shielding box 6.Outer ring at anode 3 is with cooling vaporization chamber 5.The cooling vaporization chamber is the circular ring structure of hollow, and its inwall is close to the outer surface of anode 3, and the external diameter of its internal diameter and anode 3 adapts.Be provided with above the cooling vaporization chamber 5 first magnet 4.1, below be provided with second magnet 4.2, cooling vaporization chamber 5 is fixed between two blocks of magnet 4.The outer wall of cooling vaporization chamber 5 is provided with inlet opening 5.1 and steam (vapor) outlet 5.2, also is provided with at its top to be used for the screw 5.3 that matches with shell 1.Water inlet 5.1 and steam (vapor) outlet 5.2 corresponding two middle side parts that are arranged on cooling vaporization chamber 5, water inlet 5.1 is connected with the pump 7 that drips, and steam (vapor) outlet 5.2 is communicated with cavity of microwave oven through steam pipe 8.
In use, anode 3 heating of starting working and heat up; At this moment, drip pump 8 supplies water to water inlet 5.1 through drip nozzle.Water droplet gets in the cavity of cooling vaporization chamber 5 through water inlet.Because the inwall of the outer surface of anode 3 and cooling vaporization chamber 5 is close to, cause cooling off the extreme temperatures in the vaporization chamber 5, water droplet falls into the heat that back absorption anode 3 produces in the cavity and vaporizes rapidly, is the anode cooling when producing steam.Because the shape of drip nozzle and water inlet 5.1 adapt; So drip nozzle can seal water inlet after water droplet gets into water inlet; Overflow from the water inlet thereby can prevent to cool off vaporization chamber 5 interior steam, and guarantee that steam can only be from steam (vapor) outlet 5.2 discharges.Because the steam pipe that links to each other with steam (vapor) outlet 5.2 8 is the low rubber tube of thermal conductivity factor, thus when steam gets into cavity of microwave oven through rubber tubes in cooling vaporization chamber 5 can condensation liquefaction, thus guaranteed that effectively steam is to heating cooking that food carried out.
