If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.

Referring to fig. 1, the cooking appliance of the embodiment of the present invention includes a cavity, the cavity includes a top plate 101, a bottom plate 102, a front plate 103, a back plate 201 (shown in fig. 2), a left side plate 104 and a right side plate 105, the top plate 101, the bottom plate 102, the front plate 103, the back plate 201, the left side plate 104 and the right side plate 105 together enclose a furnace body structure with an opening, and the opening is located on the front plate 103.

The cooking appliance further comprises an oven door (not shown in the figures) mounted at the position of the front plate 103 for opening or closing the opening of the oven structure. A cooking cavity 106 is formed in the cavity, food is placed in the cooking cavity 106 to be heated, and a closed space is formed in the cavity after the oven door is closed.

It is understood that the cooking appliance may be a microwave oven, an oven, a steam-baking all-in-one machine, a micro-steam-baking all-in-one machine, or the like. The following description will be made by taking a microwave oven as an example.

Referring to fig. 2, it can be understood that the storage container 202 is placed at the bottom of the cooking appliance, that is, the storage container 202 is placed on the bottom plate 102, the cooking appliance is further provided with a heat source (such as a magnetron 203 in a microwave oven), food is placed in the storage container 202, the magnetron 203 heats the food, and some heat insulation structures are arranged outside the cavity to reduce heat loss in the cooking cavity 106.

It should be noted that the storage container 202 is not an essential component of the cooking device, and some food items, such as sweet potatoes, taros and other food items with self-contained partitions, can be directly placed on the base plate for direct heating. The storage container 202 is only indicated here for better illustration of the position where the food is placed and the detection range of the temperature sensor 401, and should not be interpreted as a limitation to the protection scope of the present invention.

Due to the heat radiation effect, the objects radiate infrared rays outwards, the temperature of the objects is different, and the energy value of the infrared rays radiated outwards is also different. In the correlation technique, an infrared sensor is arranged on the inner wall of the cavity, the temperature of food is detected through the infrared sensor, the cooking appliance is further provided with a controller, and the controller is connected with the infrared sensor, so that the temperature of the food is conveniently controlled.

As can be appreciated, the viewing angle range of the infrared sensor covers the storage container 202, receives infrared rays radiated by an object within the viewing angle range, and converts the received infrared rays into a temperature value; the controller receives the temperature value transmitted by the infrared sensor, and can determine whether an object is placed on the storage container 202 and control the working state of the magnetron 203 according to the received temperature value.

In the related art, the infrared sensor is generally disposed on the left inner wall (i.e., the left side plate 104) or the right inner wall (i.e., the right side plate 105) of the cavity, so as to ensure that the viewing angle range of the infrared sensor can cover the storage container 202.

However, the infrared sensor is disposed on the left side plate 104 or the right side plate 105 of the chamber, and the angle of incidence is ensured by virtue of the inclined disposition of the infrared sensor. Therefore, the incident angle of the infrared sensor probe is greatly limited, so that the visual angle range of the infrared sensor is limited, that is, the included angle between the incident direction of the infrared sensor probe and the horizontal direction is small, in some cooking appliances with high side plates, the visual angle range of the infrared sensor mainly irradiates the side plate opposite to the cooking appliance, and the angle irradiating the storage container 202 on the bottom plate 102 is small, so that the temperature control precision is poor.

For example, the infrared sensor mounted on the right side plate 105, the viewing angle range of the infrared sensor mainly irradiates on the cooking utensil left side plate 104, and the angle irradiating on the storage container 202 on the bottom plate 102 is small, thereby causing the temperature control accuracy to deteriorate.

It should be noted that the first detecting hole 108 is not generally disposed at the middle position of the top plate 101, that is, the first detecting hole 108 is not generally disposed right above the storage container 202, because a high temperature device is disposed at the top of the cooking appliance, which may affect the detection accuracy of the temperature sensor 401. The first detecting hole 108 is disposed at the middle position of the top plate 101, and the temperature sensor 401 is also disposed at the corresponding position, that is, the temperature sensor 401 is directly projected onto the storage container 202 at the top of the cooking appliance, although the storage container 202 can be maximally irradiated, substances such as steam and oil smoke in the cooking cavity 106 flow upwards, which may contaminate the probe of the temperature sensor 401, resulting in inaccurate temperature measurement.
