Abstract
The utility model provides a temperature detection mechanism for a microwave oven. The mechanism comprises a stove body and a temperature sensor, wherein a visible light source is arranged in the oven body, light emitted from the visible light source penetrates through a detection window in the lateral wall of a furnace chamber and directly reaches foods, and the area irradiated by the light is partially or completely superposed with the detection area of the temperature sensor. According to the temperature detection mechanism, a spotlight is arranged on the temperature sensor, and the irradiation area of the spotlight is positioned in the geometric center of the detection area of the temperature sensor, so that the detection area of the temperature sensor is marked in the furnace chamber through visible light, so that a user can distinguish conveniently. Before the user cooks with the microwave oven, the food can be accurately put in the center of the detected area through the mark of the spotlight light, so that an accurate temperature value can be obtained in the cooking process, and a better cooking effect can be obtained.
Description
Technical field
The utility model relates to the temperature testing organization of a kind of micro-wave oven, particularly a kind of micro-wave oven.
Background technology
Existing micro-wave oven with infrared temperature testing agency on the market, the scan mode of its infrared temperature sensor probe are divided into two kinds of scanning constant and parallel sweeps.Because temperature sensor need to be surveyed the temperature of foodstuff surface, so object to be heated must be in the zone that temperature sensor can detect.And in the above-mentioned two schemes: the position of fixed temperature sensor 4 ' in micro-wave oven is (the seeing Fig. 1, Fig. 2) fixed, and the position of its detection, angle, scope all are extremely restricted, and Effect on Detecting is relatively relatively poor; Parallel scanning type temperature sensor 4 " be fixed on the motor of parallel motion (seeing Fig. 3, Fig. 4); do the parallel sweep motion by driven by motor during work, scope and the angle of detection are larger, so Effect on Detecting is better; but this mechanism need increase motor and accessory thereof, and cost is higher.
Chinese patent literature CN102221225 comprises being arranged on the outer sensor probe of furnace chamber in the arrangement of temperature sensor that on October 19th, 2011 disclosed a kind of micro-wave oven.Sensor probe is accepted the infrared signal that food sends and is measured food temperature by the peephole on the furnace chamber.But the sensor of this invention is traditional fixed sensor, in case food to be heated is not placed in the search coverage, the temperature that it detects and actual conditions have larger gap.Therefore, be necessary to make further improvements.
The utility model content
The purpose of this utility model aims to provide a kind of with the temperature detection area visualization, with the temperature testing organization of the micro-wave oven of accurate acquisition food temperature, to overcome the deficiencies in the prior art part.
Press the temperature testing organization of a kind of micro-wave oven of this purpose design, comprise body of heater and temperature sensor thereof, its architectural feature is to be provided with visible light source in the described body of heater, and the zone that the light that visible light source sends shines partly or entirely overlaps with the search coverage of temperature sensor.
The light that described visible light source sends passes the detecting window that is arranged on the furnace chamber sidewall, shines directly on the testee.Visible light source and temperature sensor are wholely set, and the irradiation area of visible light source is positioned at the geometric center of temperature sensor search coverage.
Described temperature sensor is fixedly installed on the outer wall of furnace chamber of micro-wave oven, receives that testee gives off, and passes the infrared ray of detecting window.Visible light source is shot-light.
The utility model arranges shot-light at temperature sensor, and makes the irradiation area of shot-light be positioned at the geometric center of temperature sensor search coverage, thereby the search coverage of temperature sensor is indicated in the furnace chamber.Before the user carrying out microwave cooking, can accurately food be positioned over the center in detected zone by the sign of shot-light light, in order in cooking process, obtain the comparatively accurately Temperature numerical of food, obtain better culinary art effect.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 5-Fig. 8, a kind of temperature testing organization of micro-wave oven comprises body of heater 1 and temperature sensor 4 thereof, is provided with shot-light at temperature sensor.The visible light that shot-light sends passes the detecting window 2 that is arranged on furnace chamber 3 sidewalls and enters furnace chamber.Because the zone that visible light indicates is positioned at the geometric center place of temperature sensor 4 surveyed areas, so the user is before to the food heating, only need to be positioned over food the irradiation area of visible light, namely can in heating process, obtain comparatively accurate food temperature.In operating process, the vessel 5 that fill food are placed in the furnace chamber 3 (such as Fig. 5), and the irradiation area of the visible light that shot-light sends is on the outer wall of vessel 5.At this moment, if heat collection with temperature data, the data that temperature sensor 4 receives are exactly the temperature of vessel 5 outer walls, rather than the temperature of food.In order to obtain accurately temperature data, the user can mobile vessel 5, make food in the vessel be positioned at the zone (such as Fig. 6) of radiation of visible light.At this moment, food is carried out heating using microwave, the data that temperature sensor 4 gathers namely are the true temperature data after food is heated.
