Abstract
The present invention relates to a heating device for a tray of an electric oven, which is composed of a capillary structure and a heat transferring mechanism, wherein the capillary structure is formed in a sealing space in a tray; the heat transferring mechanism is filled with heat transferring fluid of the sealing space and transfers heat by the phase transition of the heat transferring fluid. When the tray is heated, the temperature of the whole tray is uniformly distributed; thus, the food on the tray is uniformly heated to be cooked, and the cooking speed is further improved.
Description
One, technical field:
The present invention relates to a kind of heater of electric oven pallet, especially relate to a kind of equally distributed electric oven pallet heating device of whole pallet temperature that makes.
Two, background technology:
The inside of electric oven is provided with the furnace chamber of cooking food, and a side of furnace chamber is provided with the magnetron that produces frequency electromagnetic waves and frequency electromagnetic waves is sent into pipeline in the furnace chamber, and the bottom of furnace chamber then is provided with the pallet of food container.Be placed in food on the pallet and when starting electric oven, frequency electromagnetic waves is finished culinary art with heat food.
As shown in Figure 1, existing electric oven heater is heated tray 1 evenly, causes to occur high-temperature region and low-temperature space in the pallet 1, and therefore, the food on the pallet 1 can not obtain uniform heating, has influenced the cooking speed of food.
Three, summary of the invention:
Purpose of the present invention promptly is a kind of electric oven pallet heating device is provided so that pallet when being heated its temperature evenly distribute, thereby make the food on the pallet obtain evenly heating and improve cooking speed.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of electric oven pallet heating device is characterized in that by the capillary pipe structure that forms in the seal cavity in the pallet, is full of the heat-transfer fluid of capillary pipe structure and utilizes the heat transfer mechanism of the phase transformation realization heat transfer of heat-transfer fluid to form.
Aforesaid electric oven pallet heating device wherein is provided with the spacer more than 1 in the pallet inner sealing space, pallet inner surface and spacer surface applied have the coating that can form capillary pipe structure.
Aforesaid electric oven pallet heating device, wherein capillary pipe structure is formed by wire netting.
Aforesaid electric oven pallet heating device, wherein heat transfer mechanism is the heat pipe that is installed in the pallet.
Aforesaid electric oven pallet heating device, wherein heat transfer mechanism is the annular heat pipe that is installed in the tray bottom, it fixedly is concentric circles at interval and arranges.
Aforesaid electric oven pallet heating device, wherein heat pipe is arranged twist.
Aforesaid electric oven pallet heating device, wherein heat pipe is the concentric circles arrangement.
Aforesaid electric oven pallet heating device, wherein heat pipe is radial arrangement.
Based on above structure, the present invention can make the uniformity of temperature profile of whole pallet, thereby makes the food on the pallet obtain evenly heating, and then improves cooking speed.
Tubular heat pipe is installed in inside or bottom surface at pallet, also can obtain same effect.
Be described in further detail below in conjunction with the technical characterictic of specific embodiment electric oven pallet heating device of the present invention.
Four, description of drawings:
Fig. 1 is the Temperature Distribution schematic diagram of existing electric oven pallet.
Fig. 2, Fig. 3 are the vertical view and the cutaway views of first embodiment of the invention.
Fig. 4, Fig. 5 are the vertical view and the cutaway views of second embodiment of the invention.
Fig. 6, Fig. 7 are the vertical view and the cutaway views of third embodiment of the invention.
Fig. 8 is the vertical view of fourth embodiment of the invention.
Fig. 9 is the structural representation of heat pipe among the present invention.
Five, the specific embodiment:
As Fig. 2, shown in Figure 3, the heat transfer mechanism 10 that the capillary pipe structure 12 that forms in the seal cavity 11 of electric oven pallet heating device of the present invention by pallet 1 inside, the heat-transfer fluid 13 that is full of capillary pipe structure 12 and the phase transformation realization that utilizes heat-transfer fluid 13 are conducted heat is formed.Heat transfer mechanism 10 is the coatings that are coated in pallet 1 inner surface and spacer 14 surfaces and can form capillary pipe structure.
Electric oven pallet heating device for said structure, when pallet 1 is heated, the heat-transfer fluid 13 at its 11 interior high temperature places, inner space is subjected to elevated temperature heat and gasifies and formation pressure differential in seal cavity 11, be in heat-transfer fluid steam diffusion of the low temperature place in seal cavity 11 under action of pressure of saturation state after being heated, after discharging evaporation latent heat, be condensed into liquid and get back to evaporated along the capillary pipe structure of seal cavity 11 inner surfaces.Above-mentioned phase-change heat transfer process is carried out repeatedly, and the temperature trend of whole pallet 1 is evenly distributed, thereby makes the food on the pallet 1 obtain evenly heating and finish culinary art.
As Fig. 4, shown in Figure 5, the heat transfer mechanism of pallet 1 adopts heat pipe 15 shown in Figure 9.Heat pipe 15 is installed in the inside of pallet 1 or bottom and shape in the shape of a spiral, and seal cavity 11 forms capillary pipe structures 12 and also is full of heat-transfer fluid 13 in the pallet.
When pallet 1 is heated, heat-transfer fluids 13 in the high temperature place heat pipe 15 are subjected to elevated temperature heat and gasify and form pressure differential in heat pipe 15 inner spaces 11, heat-transfer fluid 13 steams that are in saturation state after being heated under action of pressure to the diffusion of low temperature place, discharge be condensed into liquid behind the evaporation latent heat and along the inner space capillary pipe structure 12 of 11 inner surfaces get back to evaporated.Above-mentioned phase-change heat transfer process repeats, and can make the temperature of pallet 1 be tending towards even.
As Fig. 6, shown in Figure 7, the inside of pallet 1 or bottom are provided with the annular heat pipe, and it fixedly is concentric circles at interval and arranges.The seal cavity of pallet inside forms capillary pipe structure and is full of heat-transfer fluid.Other structure is identical with Fig. 4, Fig. 5 with diabatic process, and whole pallet 1 temperature is evenly distributed.
As shown in Figure 8, the inside of pallet 1 or bottom are provided with the heat pipe 15 of a plurality of one-tenth radial arrangement, and other structure is identical with Fig. 4, Fig. 5 with diabatic process, and whole pallet 1 temperature is evenly distributed.
In sum, the present invention forms capillary pipe structure and is full of heat-transfer fluid in the pallet inner space, utilizes the phase transformation of heat-transfer fluid to realize conducting heat, and the temperature of whole pallet is evenly distributed, thereby makes the food on the pallet 1 obtain evenly heating and finish culinary art.
