Problems solved by technology

Obviously, this container is only suitable for working in the microwave state. Once it works under the grilling function, because the distance between the cooking container and the top grilling pipe is very close, even if it is a very short time, the top will have a high temperature of over 400 degrees. As a result, the plastic container in the container assembly is baked
In addition, in the actual use of microwave ovens, there are many containers with specific shapes. These containers are made of non-high-temperature-resistant plastic materials. Once the user misoperates the grill function key, it is easy to cause a safety accident.

Embodiment Construction

[0012] like figure 1 As shown, on the side of the electric appliance room of the microwave oven with barbecue function, the microwave emitted by the magnetron 4 is guided into the cavity 6 by the waveguide 5 from the bottom of the microwave oven, and a laser generator of a specific wavelength is fixed on the vertical side of the side plate of the cavity. A laser receiver 1 is fixed on the corresponding other side board. The circuit control board of the microwave oven has a separate port on the I / O, which is connected to the laser receiver 2 and is used to judge the acquisition of the receiver 2. signal of.

[0013] When the microwave oven is powered on and the user closes the oven door, the laser generator 1 will emit rays of a specific frequency band in the direction of the laser receiver 2. The frequency band and intensity of the laser rays are set so that they can pass through the space in the oven cavity but cannot penetrate solid objects. .

[0014] Simultaneously, the ...

Abstract

The invention relates to a microwave oven which can avoid error operation of barbecue function, wherein one side wall of furnace chamber is arranged with one light generator; another side wall of furnace chamber has one light receiver for transmitting signal to the circuit control board; when the light receiver can receive the light of light generator, the circuit control board will connect the barbecue function circuit; when the boiling container is arranged inside the furnace chamber, the light is blocked, to make light receiver not receive light signal, to cutoff the barbecue function circuit; therefore, even the barbecue function key is pressed, the barbecue function will not be turned on.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a microwave oven capable of preventing malfunction of the barbecue function. Background technique [0002] Microwave ovens with a grill function are very common on the market at present. Because microwaves easily penetrate plastics, it is very convenient and practical to use plastic containers when using the microwave function of microwave ovens, so plastic containers are widely used in microwave ovens. However, the temperature resistance of plastic containers is generally between 100 and 150 degrees. Such a situation often occurs. When the user places the plastic container in the cavity of the microwave oven, when the user accidentally operates the grill function key by mistake, the grill tube will be heated. The speed is extremely fast, and the temperature can easily exceed 200 degrees. At this time, the plastic container will melt quickly, causing danger. [0003] For example, in the pate...
