Abstract
In a temperature sensor of a microwave oven, a baffle which is normally opened when the microwave oven operates is arranged at an observation hole through a tension spring and a slideway, moreover, a swing rod arranged on a drive motor shaft can be utilized to push the baffle to move until the observation hole on the oven chamber is closed, the observation hole is automatically opened or closed in the process according to the operating state of the microwave oven, and a drive motor not only can change the observation angle and observation track of a sensor probe, but also can automatically judge the dimension of the swinging angle, so that the sensor probe can be effectively protected when the microwave oven is shut down. Since the movement of the baffle is completely actuated by the tension spring on the oven chamber of the microwave oven and the drive motor of the sensor probe, the independent motor for controlling the baffle in the prior art is dispensed with, consequently, the overall energy consumption of the microwave oven is reduced, the internal structure of the microwave oven becomes simpler, and the production cost of the microwave oven is reduced.
Description
Technical field
The invention belongs to the technical field of micro-wave oven, be specifically related to a kind of by being arranged on the furnace chamber outside extension spring and drive motor control furnace chamber on the switching of observation port, thereby can protect the temperature sensor of the micro-wave oven of sensor probe automatically.
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 synoptic diagram; Fig. 2 is the scheme of installation of a kind of temperature sensor of micro-wave oven in the prior art.
To shown in Figure 2, 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 as Fig. 1, also comprises being located at 40 of 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 panel 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, constitutes the food after both can having put into food and take out the cooking from opening the place ahead of furnace chamber 20 by the tetragonal chest of front openings.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 furnace chamber, be provided with rotatable pallet 60.
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 by radiator fan 35.
In the temperature sensor 70 of the micro-wave oven of prior art, sensor probe 71 is arranged on the outer sidewall of the furnace chamber 20 of micro-wave oven or is arranged on the top of furnace chamber, see through the observation port 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 electric signal is input to micro-wave oven; Sensor outer housing 72 holds protection and fixation of sensor probe.
But, there is following problem in the prior art:
In the prior art in the temperature sensor of micro-wave oven, sensor is fixed on the outer sidewall of the furnace chamber of micro-wave oven or is arranged on the top of furnace chamber, in most of the cases the observation port position on the furnace chamber is not provided with blocking-up means such as baffle plate, observation port is in the state of opening all the time, micro-wave oven foul such as dust when not working arrives sensor probe from observation port easily, causes the sensitivity of sensor probe to descend.In the temperature sensor in the prior art, even if be provided with baffle plate at the observation port place, baffle plate also is to have independent motor to carry out drive, and independent motor has improved production cost of products.
Summary of the invention
