Description
Technical Field
[0001] The utility model relates to the technical field of microwave ovens, in particular to a microwave oven with an anti-dry-burning function. Background Art
[0002] At present, microwave ovens have become a must-have appliance for almost every household, but most microwave ovens on the market ignore the hazards of dry burning. Long-term dry burning of microwave ovens will cause the following hazards: 1. Equipment damage: When the microwave oven is idling, because there is no object to consume microwaves, the microwaves will be reflected between the oven and the oven wall. Over time, it may cause damage to the magnetron, and in severe cases, it may even cause sparks. 2. Shortened service life: Long-term idling will generate a large amount of heat energy that cannot be released, which will shorten its service life. 3. Safety hazards: The heating characteristic of the microwave oven is that the vibration of water molecules generates heat. If there is no object in the oven, then this heat energy will have nowhere to dissipate, which may cause the microwave oven to malfunction or even cause a fire, posing a threat to personal safety.

[0024] The utility model will be further described below in conjunction with the accompanying drawings.
[0025] See also Figures 1 to 6 As shown, a microwave oven with an anti-dry-burning function comprises a microwave oven body 1 and an anti-dry-burning sensor 2 arranged in the inner cavity of the microwave oven body 1;
[0026] A first control unit is provided in the microwave oven body 1. The first control unit is used to control the working state of the microwave oven body 1. The working state of the microwave oven body 1 includes an on state or an off state.
[0027] The anti-dry burning sensor 2 is provided with a laser module 4, a camera module 3 and a second control unit, and the second control unit is electrically connected to the camera module 3 and the first control unit, wherein:
[0028] The laser module 4 is used to emit laser beams into the inner cavity of the microwave oven body 1;
[0029] The camera module 3 is used to collect the pattern of the light spot formed by the laser beam emitted by the laser module 4 in the inner cavity of the microwave oven body 1;
[0030] The second control unit is used to determine whether the inner cavity of the microwave oven body 1 is empty and whether there is a dry burning phenomenon in combination with the working state of the microwave oven body 1 and send a control instruction for the microwave oven body 1 to the first control unit, thereby controlling the working state of the microwave oven body 1.
[0031] In this embodiment, illustratively, the line laser emitted by the laser module 4 is infrared light.
[0032] According to the above design, the utility model adds an anti-dry-burning sensor 2 designed based on the laser module 4, the camera module 3 and the second control unit in the inner cavity of the microwave oven body 1. The laser module 4 first emits a laser beam into the inner cavity of the microwave oven body 1, and then the camera module 3 collects the pattern of the light spot formed by the laser beam emitted by the laser module 4 in the inner cavity of the microwave oven body 1. Subsequently, the second control unit compares and analyzes it with the pattern of the light spot formed by the laser beam emitted by the laser module 4 in the inner cavity of the microwave oven body 1 in an empty state, and then determines whether the inner cavity of the microwave oven body 1 is in an empty state, and then determines whether there is a dry-burning phenomenon in combination with the working state of the microwave oven body 1, and takes corresponding measures (when there is a dry-burning phenomenon, a control instruction is sent to shut down the microwave oven body 1, and when there is no dry-burning phenomenon, no control instruction is sent), thereby achieving the purpose of preventing dry-burning.
[0033] See also Figures 2 to 6 As shown, with regard to the structural design, specifically, the anti-dry burning sensor 2 also includes a front shell 5 and a rear shell 6, which are snap-fitted and spliced together, and an installation cavity is formed therebetween, and an opening 5-1 is provided on the front side of the front shell 5, the laser module 4 and the camera module 3 are both fixed in the installation cavity, and the emitting end of the laser module 4 and the receiving end of the camera module 3 are both facing the opening 5-1.
[0034] The anti-dry-burning sensor 2 can be embedded in the side wall of the inner cavity of the microwave oven body 1, or embedded in the inner corner of the inner cavity of the microwave oven body 1, or the above two arrangements can be combined. For example, the anti-dry-burning sensor 2 is embedded in the two pairs of side walls of the inner cavity of the microwave oven body 1 and is located in the middle, such as Figure 3 , the two anti-dry-burning sensors 2 work, and there is almost no blind spot in this arrangement, or the anti-dry-burning sensor 2 is embedded in one of the inner corners of the inner cavity of the microwave oven body 1, such as Figure 4 , this arrangement also has almost no blind spots.
[0035] The above technical solution is preferably designed as follows:
[0036] The laser beam emitted by the laser module 4 is parallel to the storage table in the microwave oven body and is emitted into the inner cavity of the microwave oven body 1 to form an optimal coverage area. It is further preferred that the laser module 4 should be as close to the storage table in the microwave oven body 1 as possible;
[0037] A transparent lens 7 is sealed and embedded in the opening 5-1 to prevent dirt. Preferably, the transparent lens 7 is a filter, and the filter parameters of the filter 7 are adapted to the line laser emitted by the laser module 4 to filter out non-target light and reduce interference.
[0038] In general, the utility model can independently determine whether dry-burning phenomenon exists in the microwave oven body 1 and take corresponding measures, so that the microwave oven has the function of preventing dry-burning.
[0039] Of course, the above are only preferred implementations of the present utility model, and are not intended to limit the scope of use of the present utility model. Therefore, any equivalent changes made to the principles of the present utility model should be included in the protection scope of the present utility model.
