Description

The temperature sensor of micro-wave oven
Technical field
The invention belongs to the technical field of micro-wave oven, be specifically related to a kind of on sensor outer housing, arrange respectively main fixed part and auxiliary retention portion, that sensor outer housing fixes with upper edge, furnace chamber 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 after power connection, and these microwave irradiations on the heating objects such as food and the device of cooking food.Such micro-wave oven can be divided into the home-use micro-wave oven that is equipped with small size magnetic keyholed back plate and the business micro-wave oven that is equipped with large-scale or multiple 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 rotary disc mode of food, and business mainly adopts the figure of confusion mode of scattered radiation microwave with micro-wave oven.Business is mainly applicable to convenience store that utilization rate is high and the food supply retail shop of cooking food at short notice with micro-wave oven, so generally need the relatively high output of more home-use micro-wave oven.
Fig. 1 is the structural representation of micro-wave oven; Fig. 2 is the schematic diagram of the 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 and is located at furnace chamber 20 door 40 above.Right-hand member at the lateral surface of door 40 is provided with handle, and the two ends of handle and door 40 are screwed connection.Shell forms micro-wave oven outward appearance, also plays the effect of the inner furnace chamber 20 of protection simultaneously, and therefore shell is generally made of the steel plate with some strength.Shell comprise by cover simultaneously furnace chamber 20 above and base plate 13 below of the top panel 11 of two sides, protection, forms the front panel 15 before furnace chamber 20 and protects the rear board 17 at furnace chamber 20 back sides.Furnace chamber 20 is spaces of the cooking things such as cooking food, is made up of the tetragonal chest of front openings, both can put into food and take out the food the cooking from the opening front of furnace chamber 20, is provided with the barbecue tube 21 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 the electricity storage chamber 30 for electronic unit is set, and electricity storage chamber 30 inside are provided with multiple electronic units such as transformer 31, magnetron 33, capacitor 37.Before electricity storage chamber 30, be provided with control panel assembly 26.
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.Sub-panel and base plate 13 above between at intervals.
In multiple electronic units, transformer 31 and magnetron 33 produce the microwave that irradiates furnace chamber 20 inside.Electronic unit generates heat in the process that produces microwave, so in the time of cooking food, the temperature rise of electricity storage chamber 30.Need to suck extraneous air for the electricity storage chamber 30 of cooling 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 forming on furnace chamber and receive the infrared signal that in furnace chamber, food sends and also measure food temperature, temperature signal is converted to the signal of telecommunication and is input to the controller of micro-wave oven; Sensor outer housing 60 is arranged on furnace chamber 20 outsides by fixed part 61, is combined into by outer casing upper cover 60a and shell lower cover 60b two parts, holds and protects sensor probe; Probe hole 62 is formed on the through hole on shell lower cover 60b, makes sensor probe can accept thermal signal.
But, in prior art, there is following problem:
In the prior art, sensor outer housing is by being arranged on the single fixed part covering under outer casing upper cover or shell, utilize on the outside of screw and furnace chamber along fixing, this fixed structure is relatively simple, but owing to being only connected by a fixed part between whole temperature sensor and furnace chamber, temperature sensor is in unsettled state, therefore stress can occur on fixed part concentrates, if jolted in the transportation of micro-wave oven, temperature sensor can produce a larger moment of torsion to the fixed position in fixed part and furnace chamber outside, thereby easily cause fixed part to rupture, cause the damage of product.
Summary of the invention
The present invention provides a kind of on sensor outer housing, arrange respectively main fixed part and auxiliary retention portion for solving the technical problem existing in prior art, that sensor outer housing fixes with upper edge, furnace chamber 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 existing in 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 forming on furnace chamber and receive the infrared signal that in furnace chamber, food sends and also measure food temperature, temperature signal is converted to the signal of telecommunication and is input to the controller of micro-wave oven; Sensor outer housing; be arranged on furnace chamber outside by fixed part; be combined into by outer casing upper cover and shell lower cover two parts; hold and protect sensor probe; above-mentioned standing part is main fixed part and auxiliary retention portion two parts, and main fixed part is arranged on outer casing upper cover, and fixes to the upper edge of outside bending with furnace chamber; auxiliary retention portion is arranged on outer casing upper cover simultaneously, fixes with the rear board of micro-wave oven.
The present invention can also adopt following technical measures:
One end of described main fixed part is fixed on the top of outer casing upper cover, and extends to form the main fixed arm of strip of bending to the top of furnace chamber, forms fixed via at the end of main fixed arm.
Described main fixed part and outer casing upper cover are formed as one.
