Abstract

The invention discloses a wave transferring furnace, including a cooking chamber and an electrical control chamber, wherein the cooking chamber is positioned in a chamber center, and the electrical control chamber is arranged on one side of the cooking chamber; the electrical control chamber includes a magnetron, a high-voltage transformer and a high-voltage capacitor as well as a wave-guide which guides the flow direction of microwaves; the entrance of the wave-guide connects with a microwave transmitting side of the magnetron, while the exit of the wave-guide connects with the up and down microwave entrances of the cooking chamber. The invention has the advantages that the microwave transmitted by the magnetron gets into the entrance of the wave-guide and then is reflected continuously to the up and down plackets of the chamber through the wave-guide; as the microwave is transmitted from both the upper and the lower parts of the chamber, an even heat absorption is secured for both the upper and the lower parts of foods in the chamber, thus the food heating is more uniform with a higher heating efficiency.

Description

The microwave plumbing of wave-rotating furnace

Technical field

The present invention relates to a kind of wave-rotating furnace, particularly relate to a kind of microwave plumbing of wave-rotating furnace.

Background technology

Microwave is a kind of high frequency waves, velocity transformation with per second 2,400,000,000 times, cause the high-speed motion of hydrone, friction generates heat mutually to make hydrone, to reach purpose to the food heating, can be simultaneously to heating inside and outside the food, so microwave is used widely in the culinary art of a variety of foods.

Wave-rotating furnace is a kind of improvement to microwave oven, wave-rotating furnace rotates by distinctive commentaries on classics ripple device changes wave beam, allow microwave rotate, with the mechanical rotation of rotating the alternative conventional microwave oven rotating disk of microwave energy, be " dish does not change ripple and changes ", wave-rotating furnace adopts no dish design to solve problems such as the heat efficiency that conventional microwave oven causes by the side-emitted microwave is low, microwave heating food effect mouthfeel, and cleaning is got up convenient.

Also has a kind of microwave oven in the microwave oven now with degassing function, be arranged on the wall corresponding to gas-cooker top, microwave oven is except having basic heating function, can also be discharged to the outside to hot gas and the flue gas that the gas-cooker of below produces, the waveguide of microwave oven is arranged on cavity top.Fig. 1 is the profile schematic diagram of the microwave oven of prior art, and as shown in Figure 1, microwave oven 10 comprises cavity and electric control chamber, and the body of heater profile is cuboid, and the inner chamber of body of heater constitutes cooking space-culinary art chamber 20, and food can be placed in culinary art 20 inside, chamber.Culinary art chamber 20 is formed by connecting its front openings by the bending of a lot of piece metallic plate.

The core of existing microwave oven cavity assembly is a cooking room 20.One side of cavity assembly is provided with the electronic unit that produces microwave.The electronic unit that is arranged on cavity assembly side comprises: vibration produces the magnetron 30 of microwave, and the high-tension transformer 40 and the capacitor 50 of high voltage source is provided; The microwave that magnetron 30 produces transmits microwave by waveguide 60 to cooking room 20.

As shown in Figure 2, the magnetron 3 of another wave-rotating furnace 2 is arranged on the cavity side, waveguide 5 is connected extension to the furnace chamber bottom with magnetron 3, the microwave of magnetron 3 emissions acts on the cavity bottom of wave-rotating furnace by waveguide 5, by blender microwave is rotated, microwave directly affacts on the heated food.

But, there is following shortcoming in existing wave-rotating furnace: microwave is from cavity top or heat heating object the cavity bottom, microwave is uniformly dispersed at grade, and heating object always be divided near microwave portion with relative away from microwave portion, food near microwave portion is warmmer than relative place away from microwave portion, makes the food temperature of heating inhomogeneous.

Summary of the invention

Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, and the wave-rotating furnace of the upper and lower thermally equivalent of a kind of heated food is provided.

The technical solution used in the present invention is: wave-rotating furnace comprises culinary art chamber and electric control chamber, and described culinary art chamber is arranged on the cavity center, and described electric control chamber is arranged on culinary art chamber one side, and electric control chamber comprises magnetron, high-tension transformer and high-voltage capacitor; Described electric control chamber also comprises waveguide, and the inlet of described waveguide is communicated with the microwave transmitting terminal of magnetron.

The output of described waveguide is a two-way, and waveguide is communicated with the top microwave entrance of wave-rotating furnace culinary art chamber, and waveguide is communicated with the bottom microwave entrance of wave-rotating furnace culinary art chamber.

The invention has the beneficial effects as follows: the magnetron launched microwave enters the waveguide inlet, microwave enters the back constantly reflexes to cavity by waveguide upper and lower opening, because cavity all has the microwave emission up and down, make the microwave amount unanimity of the upper and lower absorption of food in the cavity, make the food heating more even, the heat efficiency is higher.

Description of drawings

Below in conjunction with the drawings and specific embodiments the present invention is done a detailed description:

Fig. 1 be in the prior art magnetron at the schematic diagram on microwave oven cavity top;

Fig. 2 be in the prior art microwave by the schematic diagram of waveguide from culinary art chamber lower heating;

Fig. 3 is the schematic diagram that microwave heats up and down from the culinary art chamber by waveguide up and down among the present invention.

Embodiment

Wave-rotating furnace comprises culinary art chamber 200 and electric control chamber 300, and described culinary art Room 200 are arranged on the cavity center, and described electric control chamber 300 is arranged on culinary art chamber 200 1 sides, and electric control chamber 300 comprises magnetron 310, high-tension transformer (not shown) and high-voltage capacitor (not shown); Structure same as the prior art repeats no more.

Described electric control chamber also comprises waveguide 320,330, and the inlet of described waveguide 320,330 is communicated with the microwave transmitting terminal of magnetron 310.Microwave by magnetron 310 emissions enters waveguide 320 by the waveguide inlet, 330, described waveguide 320,330 output is a two-way, waveguide 320 is communicated with the top microwave entrance of wave-rotating furnace culinary art chamber 200, promptly, described waveguide 320 is communicated with the top microwave entrance of culinary art chamber 200 along the sidewall bending back of described culinary art chamber 200, waveguide 330 is communicated with the bottom microwave entrance of wave-rotating furnace culinary art chamber 200, promptly, described waveguide 330 is communicated with the bottom microwave entrance of culinary art chamber 200 along the sidewall bending back of described culinary art chamber 200, by waveguide 320, the outlet that 330 continuous reflection is delivered to waveguide to microwave is radiated to culinary art chamber 200, food to the culinary art chamber evenly heats, by lay respectively at the culinary art chamber 200 on, the microwave entrance of bottom, microwave sends in streams to a place on the food of culinary art chamber 200, because cavity all has the microwave emission up and down, make on the food of culinary art chamber 200, the microwave amount unanimity of following absorption makes the food heating more even, and the heat efficiency of microwave is higher.
