Example one

The embodiment provides a kitchen appliance, and particularly, the kitchen appliance can be but is not limited to a range hood, an integrated stove and the like. In this embodiment, a kitchen appliance is taken as an example of a range hood and described in detail. It should be noted that in the present embodiment, the descriptions of the front, rear, left, right, up, down, and the like are all based on the position of the range hood relative to the user.

As shown in fig. 1-3, the range hood comprises a frame 1, the frame 1 comprises a panel 11, and the panel 11 is a plate member at the outermost side of the range hood. Optionally, the panel 11 may be a glass plate or a metal plate, which is good in appearance and convenient to clean. The lampblack absorber of this embodiment still includes temperature sensing module 2, temperature sensing module 2 installs the internal surface in frame 1, specifically be panel 11's inboard, be provided with the trompil on the panel 11, temperature sensing module 2 sends or receives the light path and passes through the temperature of trompil in order to detect the cooking utensils or the mesa of frame 1 below, temperature sensing module 2 can be with the temperature data output who detects for the control module of lampblack absorber, the control module of lampblack absorber can correspond the mode of adjusting the oil absorption cigarette according to the detection structure of temperature sensing module, make the lampblack absorber can assist the user to adjust the mode of oil smoke absorption cigarette through the cooperation of temperature sensing module and control module promptly.

As shown in fig. 3, the temperature sensing module 2 includes a main body 21, a mounting plate 22, and a first wire assembly 24, the mounting plate 22 is connected to the outside of the main body 21, and the mounting plate 22 is used for connecting the temperature sensing module 2 to other components. The body portion 21 includes a housing, a detection probe 213, and a circuit board 214. Wherein the casing is formed with and holds the chamber, and test probe 213 and circuit board 214 all set up and are holding the intracavity, and test probe 213 is connected with circuit board 214 electricity, and first wire assembly 24 one end is connected with circuit board 214 electricity, and the other end stretches out to the casing outside and be connected with the control module of lampblack absorber. The temperature sensing module 2 constitutes an integral structure, so that independent maintenance and replacement are facilitated, and the shell can protect the detection probe 213 and the circuit board 214, so that the service life of the temperature sensing module 2 is prolonged. Be provided with light-permeable opening 215 on the casing, light path that test probe 213 sent or received passes through from light-permeable opening 215, and then realizes detecting the outside temperature of casing, and test probe 213 detects temperature data and sends circuit board 214, and circuit board 214 sends corresponding control command to the control module of lampblack absorber according to the temperature data that receive. Because the detection probe 213 and the circuit board 214 are both arranged in the shell, the communication distance between the detection probe 213 and the circuit board 214 is short, so that the circuit board 214 can quickly receive the temperature data detected by the detection probe 213, and in addition, the temperature data cannot be distorted due to the communication path end. Because the control instruction sent by the circuit board 214 to the control module of the range hood is carried out in a simple binary form, the control instruction is less influenced by a longer communication path, and the accurate control of the range hood is not influenced. The detection probe 213 and the circuit board 214 are electrically connected by a second wire assembly.

Besides the two types, any infrared temperature measuring sensor capable of realizing non-contact measurement of the temperature of the object to be measured is within the protection scope of the technical scheme of the invention. When the detection probe 213 is an active infrared temperature sensor, the infrared rays emitted by the detection probe 213 pass through the light-transmitting opening 215 and then are transmitted to the outside of the range hood through the opening, and the light rays reflected by the infrared rays contacting the object pass through the opening on the panel 11 and then pass through the light-transmitting opening 215 to be received by the detection probe 213. For the detection probe 213 being an active infrared temperature sensor, infrared rays radiated from an external cooker or a table top pass through the opening of the panel 11 and then pass through the light-transmitting opening 215 to be received by the detection probe 213, so that the detection probe 213 can detect the temperature.

In this embodiment, a kitchen appliance is taken as an example to be introduced. In this embodiment, the working principle of the range hood, the concept that the temperature sensing module 2 and the protective cover 3 are integrated and then installed in the panel 11 are the same as those of the first embodiment, and the same parts are not described herein again. The difference mainly lies in proposing a new temperature sensing module 2 and new installing support 4, and temperature sensing module 2 installs on installing support 4 with new connected mode, specifically as follows:

The protection cover 3 can be connected with the two supporting plates 47 respectively, and the relative positions of the two limiting plates 46 can be fixed. In this embodiment, if an opening is provided above the shield 3, the temperature sensing module 2 is mounted between the two stopper plates 46 from top to bottom, and if an opening is provided below the shield 3, the temperature sensing module 2 is mounted between the two stopper plates 46 from bottom to top.

In this embodiment, as shown in fig. 7, the mounting bracket 4 further includes a connecting portion 41, and the connecting portion 41 is used to mount the mounting bracket 4 on the panel 11. Specifically, the mounting bracket 4 includes two connecting portions 41, and each connecting portion 41 is connected to one of the limiting plates 46. The connecting portion 41 is located on a side of the stopper plate 46 facing the panel 11 and is disposed parallel to the panel 11. The detailed structure of the connection portion 41 and the specific connection manner between the connection portion 41 and the panel 11 in this embodiment are the same as those in the first embodiment, and are not described again.
