Description
Technical field
The invention belongs to the technical field of micro-wave oven, be specifically related to a kind of main fixed part and auxiliary retention portion of on sensor outer housing, being provided with respectively, be that sensor outer housing fixes with furnace chamber upper edge, the outside and rear board simultaneously, thereby make the fixed position of sensor more accurate, and the temperature sensor of the more firm micro-wave oven of constant intensity.
Technical background
Micro-wave oven is that magnetron produces microwave behind power connection, and these microwave irradiations on heating objects such as food and the device of cooking food.Such micro-wave oven can be divided into home-use micro-wave oven that is equipped with small-sized magnetron and the commerce micro-wave oven that is equipped with large-scale or a plurality of magnetrons.Micro-wave oven can also be divided into home-use micro-wave oven according to the mode of heat food and generally adopt rotation to fill the glass rotating disk mode of food, and commerce mainly adopts the figure of confusion mode of scattered radiation microwave with micro-wave oven.Commercial mainly be applicable to the convenience store that utilization rate is high and the food supply retail shop of cooking food at short notice, so generally need the high relatively output of more home-use micro-wave oven with micro-wave oven.
Fig. 1 is the microwave oven structure schematic diagram; Fig. 2 is the schematic diagram of temperature sensor set-up mode of the micro-wave oven of prior art; Fig. 3 be prior art the schematic diagram of temperature sensor of micro-wave oven.
As shown in Figure 1 to Figure 3, micro-wave oven comprises by the shell that forms outward appearance, furnace chamber 20 and is positioned at the electricity storage chamber 30 of furnace chamber 20 right side sides, also comprises the door 40 that is located at furnace chamber 20 fronts.Right-hand member at the lateral surface of door 40 is provided with handle, and the two ends of handle are screwed with door 40 and are connected.Shell forms the micro-wave oven outward appearance, also plays the effect of the inner furnace chamber 20 of protection simultaneously, so shell generally will be made of the steel plate with certain intensity.Shell comprises the rear board 17 at the base plate 13 below the top panel 11 of the top and two sides that cover furnace chamber 20 simultaneously, protection, the front panel 15 that forms furnace chamber 20 fronts and protection furnace chamber 20 back sides.Furnace chamber 20 is spaces of cooking such as cooking food thing, is made of the tetragonal chest of front openings, and the food after both can having put into food and take out the cooking from opening the place ahead of furnace chamber 20 is provided with the barbecue tube 21 that is used for baking food on the top of furnace chamber.There is certain space the right side side of furnace chamber 20, and this space is to be the electricity storage chamber 30 that electronic unit is set, and electricity storage chamber 30 inside are provided with a plurality of electronic units such as transformer 31, magnetron 33, capacitor 37.Be provided with control panel assembly 26 in the front of electricity storage chamber 30.
In addition, the inside of electricity storage chamber 30 is provided with demarcation strip 39 between transformer 31 and radiator fan 35.Transformer 31, radiator fan 35, capacitor 37 and demarcation strip 39 be fixed on sub-panel above.Between sub-panel and base plate 13 top at intervals.
In a plurality of electronic units, transformer 31 and magnetron 33 produce the microwave of irradiation furnace chamber 20 inside.Electronic unit generates heat in the process that produces microwave, so in the time of cooking food, the temperature of electricity storage chamber 30 rises.Need to suck extraneous air for the electricity storage chamber 30 of cooling off heating, so radiator fan 35 sucks extraneous air.
In the arrangement of temperature sensor of the micro-wave oven of prior art, sensor probe is arranged on outside the furnace chamber 20 of micro-wave oven, see through the peephole that forms on the furnace chamber and receive the infrared signal that food sends in the furnace chamber and measure food temperature, temperature signal is converted to the controller that the signal of telecommunication is input to micro-wave oven; Sensor outer housing 60 is installed in furnace chamber 20 outsides by fixed part 61, by outer casing upper cover 60a and shell lower cover 60b two parts be combined into, holds and protects sensor probe; Probe hole 62 is formed on the through hole on the shell lower cover 60b, makes sensor probe can accept thermal signal.
But, there is following problem in the prior art:
In the prior art, sensor outer housing is by being arranged on the single fixed part that covers under outer casing upper cover or the shell, utilize the outside upper edge of screw and furnace chamber to fix, this fixed structure is simple relatively, but owing to only be connected between whole temperature sensor and the furnace chamber by a fixed part, temperature sensor is in unsettled state, therefore stress can take place on fixed part concentrates, if in the transportation of micro-wave oven, jolt, temperature sensor can produce a bigger moment of torsion to the fixed position in the fixed part and the furnace chamber outside, thereby cause fixed part to rupture easily, cause the damage of product.
Summary of the invention
The present invention provides a kind of main fixed part and auxiliary retention portion of being provided with respectively for solving the technical problem that exists in the prior art on sensor outer housing, be that sensor outer housing fixes with furnace chamber upper edge, the outside and rear board simultaneously, thereby make the fixed position of sensor more accurate, and the temperature sensor of the more firm micro-wave oven of constant intensity.
The technical scheme that the present invention takes for the technical problem that exists in the solution prior art is:
The temperature sensor of micro-wave oven of the present invention, comprise: sensor probe, be arranged on outside the furnace chamber of micro-wave oven, see through the peephole that forms on the furnace chamber and receive the infrared signal that food sends in the furnace chamber and measure food temperature, temperature signal is converted to the controller that the signal of telecommunication is input to micro-wave oven; Sensor outer housing; be installed in the furnace chamber outside by fixed part; by outer casing upper cover and shell lower cover two parts be combined into; hold and protect sensor probe; said fixing partly is main fixed part and auxiliary retention portion two parts, and main fixed part is arranged on the outer casing upper cover, and fixes with the upper edge of furnace chamber to the outside bending; auxiliary retention portion is arranged on the outer casing upper cover simultaneously, fixes with the rear board of micro-wave oven.
The present invention can also adopt following technical measures:
