The embodiment provides a kitchen appliance with a fume removing function, which can be a range hood or an integrated kitchen range. In this embodiment, the kitchen appliance is a range hood.

As shown in fig. 1 and 2, the range hood includes a main body 50, a fume collecting hood 30, a mounting panel 10, and a movable panel 40. The main machine 50 is arranged above the cooking bench, the bottom of the main machine 50 is connected with the fume collecting hood 30, the fume collecting hood 30 is provided with a fume inlet, a filter screen is arranged in the fume inlet, and a fume exhaust channel communicated with the fume inlet is arranged in the main machine 50. The fan is arranged in the smoke exhaust channel. After the fan is started, the air below the fume collecting hood 30 can be filtered through the filter screen at the fume inlet, and then is sucked into the fume exhaust channel and is discharged outdoors through the fume exhaust channel, so that the aim of purifying the kitchen environment is fulfilled.

The installation panel 10 is fixed on the fume collecting hood 30, and the top end of the movable panel 40 is rotatably connected with the fume collecting hood 30, so that the movable panel 40 can close the fume inlet or open the fume inlet. When the movable panel 40 closes the smoke inlet, the movable panel 40 and the installation panel 10 are spliced into a whole to decorate the surface of the smoke collecting hood 30, thereby improving the beautiful appearance.

In order to make the range hood more intelligent, the range hood further comprises a temperature sensing module 20, wherein the temperature sensing module 20 is arranged on the body mounting panel 10 so as to be positioned above the cooking bench, and the temperature sensing module 20 is used for detecting the temperature in a preset range on the cooking bench, and the burner is positioned in the preset range. Further, the temperature sensing module 20 is in communication with the fan. The temperature in the preset range is detected through the temperature sensing module 20, so that the range hood can automatically adjust the gear of the fan corresponding to different temperatures, and the oil smoke can be purified more intelligently. In this embodiment, the temperature sensing module 20 is an infrared temperature sensing module, and the temperature is determined by measuring infrared radiation.

It should be noted that, the preset range is a coverage area of the receiving field of the temperature sensing module 20 on the stove, and the burner corresponding to the temperature sensing module 20 is located in the coverage area. When the cooker is not placed on the burner, the temperature sensing module 20 mainly detects the temperature of the burner; when a cooker is placed on the burner, the temperature sensing module 20 mainly detects the bottom temperature of the cooker placed on the burner.

In order to improve the appearance consistency of the range hood, the temperature sensing module 20 is arranged at the inner side of the fume collecting hood 30, the mounting panel 10 is provided with a through hole 111, and the temperature sensing module 20 receives infrared radiation through the through hole 111, so as to detect the temperature.

The conventional temperature sensing module 20 is generally embedded in the range hood and is fixed by a bracket. After the temperature sensing module 20 is embedded, the temperature sensing module 20 needs to be flush with the embedded piece, otherwise, the detection precision of the temperature sensing module 20 and the appearance of the kitchen appliance cannot be guaranteed. Therefore, the fixing method has very high requirements on the dimensional accuracy of the bracket and the temperature sensing module 20, and the bracket process is difficult to ensure. In addition, in the actual installation process of the kitchen appliance, the assembly precision of the temperature sensing module 20 is difficult to ensure under the influence of the installation environment and the assembly personnel level, and the problem of inaccurate temperature measurement caused by larger installation errors exists.

To solve the above problems, as shown in fig. 3, the temperature sensing module 20 includes a temperature sensing housing 21, a temperature sensing probe assembly 22, and an elastic member 23. The temperature sensing shell 21 is arranged on the mounting panel 10, a mounting cavity is defined between the temperature sensing shell 21 and the mounting panel 10, the temperature sensing probe assembly 22 is arranged in the mounting cavity, and the receiving end of the temperature sensing probe assembly 22 faces the through hole 111; the elastic member 23 is disposed between the temperature sensing housing 21 and the temperature sensing probe assembly 22, and the elastic member 23 abuts against the temperature sensing probe assembly 22 to press the temperature sensing probe assembly 22 toward the mounting panel 10. Through setting up elastic component 23, realize the flexible coupling of temperature sensing shell 21 and temperature sensing probe subassembly 22, can compress tightly temperature sensing probe subassembly 22 on installation panel 10 in parallel, make the angle deviation of temperature sensing probe subassembly 22 little, guarantee the installation accuracy of temperature sensing probe subassembly 22 to improve the test accuracy. The structure has low requirements on the proficiency of assembly personnel and low operation difficulty.

Further, in order to better reduce the angular deviation of the temperature sensing probe assembly 22, the side of the temperature sensing probe assembly 22 facing the mounting panel 10 is provided with an abutment plane 2211, the abutment plane 2211 being for abutment with the mounting panel 10. When the temperature sensing probe assembly 22 is prepared, by ensuring that the end surface of the receiving end of the temperature sensing probe assembly 22 is located at a preset angle (for example, may be parallel) to the abutting plane 2211, it is possible to ensure that the end surface of the receiving end of the temperature sensing probe assembly 22 is located at a preset angle to the mounting panel 10 when the abutting plane 2211 abuts against the mounting panel 10, so as to further reduce the angular deviation of the temperature sensing probe assembly 22.

In addition, the mounting angle of the temperature sensing probe assembly 22 can be ensured by only improving the machining precision of the abutting plane 2211, and the machining difficulty and the machining cost are reduced.

In some embodiments, the installation cavity may be formed only by the temperature-sensing casing 21, the temperature-sensing casing 21 is abutted with the installation panel 10, and the temperature-sensing probe assembly 22 is disposed in the installation cavity and is pressed against the inner wall of the temperature-sensing casing 21 under the elastic force of the elastic member 23. This kind of setting can guarantee the installation angle of temperature sensing probe subassembly 22 in temperature sensing shell 21, and then guarantees the installation angle of temperature sensing probe subassembly 22 relative installation panel 10, also can reach the angle deviation that reduces temperature sensing probe subassembly 22, and then improves the effect of test accuracy.

In this embodiment, the elastic member 23 is an elastic pad made of an elastic material, and the elastic pad is compressed between the temperature sensing housing 21 and the temperature sensing probe assembly 22, so as to compress the temperature sensing probe assembly 22 by using an elastic force generated by deformation of the elastic pad, so as to ensure an installation angle of the temperature sensing probe assembly 22.

To ensure that the elastic pad is in a compressed state, the distance H between the surface of the side of the temperature sensing probe assembly 22 facing away from the mounting panel 10 and the inner wall of the temperature sensing housing 21 is smaller than the thickness of the elastic pad in a natural state, so as to ensure that the elastic pad can be stressed and compressed after being mounted in the temperature sensing housing 21, so as to provide elastic pressure for the temperature sensing probe assembly 22.

To ensure the stable position of the elastic pad, the elastic pad may be adhered to at least one of the temperature sensing housing 21 and the temperature sensing probe assembly 22, so as to avoid deviation of the angle of the temperature sensing module 20 caused by the position movement of the elastic pad.

Alternatively, the resilient pad may be made of sponge, silicone or rubber, which can apply pressure to the temperature sensing probe assembly 22 to compress the temperature sensing probe assembly 22 against the mounting panel 10.

In order to facilitate the installation of the temperature sensing module 20, the temperature sensing housing 21 comprises a cylinder 211 and an upper cover 212, wherein the bottom end of the cylinder 211 is installed on the installation panel 10, and the upper cover 212 is detachably connected with the cylinder 211 and seals the top end opening of the cylinder 211. Optionally, the upper cover 212 is fixed to the cylinder 211 by a first screw 213, the upper cover 212 includes a top plate and a side plate circumferentially disposed around the top plate, the side plate covers the circumferential outer wall of the cylinder 211, and the first screw 213 fixedly connects the side plate and the cylinder 211.

To facilitate the fixation of the cylinder 211 to the mounting panel 10, as shown in fig. 3 and 4, the mounting panel 10 includes an outer decorative plate 11 and an inner lining plate 12, the outer decorative plate 11 is provided with a through hole 111, the inner lining plate 12 is fixed to the inner side of the outer decorative plate 11, the inner lining plate 12 is provided with a mounting hole 122, the mounting hole 122 corresponds to the position of the through hole 111, and the inner lining plate 12 is provided with an abutting portion 121 around the mounting hole 122. The cylinder 211 is located in the mounting hole 122 and is opposite to the through hole 111, and a flange plate is connected to the bottom end of the cylinder 211, and the abutting portion 121 abuts against the flange plate to press the flange plate toward the outer decorative plate 11, thereby fixing the cylinder 211 to the mounting panel 10. The fixing flange plate is clamped by matching the inner lining plate 12 and the outer decorative plate 11, so that the cylinder 211 and the mounting panel 10 are fixed, and the mounting is convenient.

To avoid damaging the appearance of the outer decorative plate 11, the inner liner 12 and the outer decorative plate 11 are fixed by adhesive bonding so as to avoid forming a hole or the like in the outer decorative plate 11. Alternatively, the outer decorative panel 11 may be a glass panel.

To further enhance the fixing effect on the cylinder 211, as shown in fig. 3, the abutting portion 121 includes a first plate 1211, a second plate 1212, and a third plate 1213 connected in this order, the first plate 1211 being perpendicular to the inner liner 12, the second plate 1212 being perpendicular to the first plate 1211 and extending inward of the mounting hole 122, the first plate 1211 and the third plate 1213 being parallel, the third plate 1213 extending away from the outer decorative plate 11; the second plate 1212 abuts a side of the flange plate facing away from the outer trim panel 11, and the third plate 1213 abuts an outer sidewall of the cylinder 211. The first plate 1211 and the second plate 1212 form a space for sandwiching the flange plate, and the second plate 1212 abuts against the flange plate to fix the cylinder 211 in cooperation with the outer decorative plate 11. The third plate 1213 abuts against the outer side wall of the cylinder 211, thereby limiting the cylinder 211 and improving the stability of the cylinder 211.

It should be noted that, the mounting hole 122 is larger than the through hole 111, so that a portion of the outer decorative plate 11 located in the mounting hole 122 can be abutted against the temperature sensing probe assembly 22, so as to ensure the mounting angle of the temperature sensing probe assembly 22 under the action of the elastic member 23, reduce the mounting deviation, and improve the accuracy of the detection result of the temperature sensing probe assembly 22.

Further, the abutting portion 121 and the cylinder 211 are adhered and fixed, so that on one hand, the fixing effect of the cylinder 211 can be further improved, and on the other hand, a gap between the abutting portion 121 and the cylinder 211 can be plugged by glue, so that oil smoke is prevented from entering the temperature sensing shell 21 through the gap, and the detection result of the temperature sensing module 20 is prevented from being influenced.

Alternatively, the second plate 1212 may be fixed to the flange plate, the third plate 1213 may be fixed to the outer peripheral surface of the cylinder 211, or the second plate 1212 may be fixed to the flange plate, the third plate 1213 may be fixed to the outer peripheral surface of the cylinder 211, so as to fix the cylinder 211 and seal the assembly gap.

The temperature sensing probe 222 is disposed toward the light transmitting hole, and infrared radiation is received by the temperature sensing probe 222 through the through hole 111 and the light transmitting hole to sense temperature. The limiting flange 2212 extends into the through hole 111, and the elastic piece 23 abuts against the temperature-sensitive inner shell 221, so as to push the abutting plane 2211 of the temperature-sensitive inner shell 221 to abut against the inner side surface of part of the mounting panel 10 in the mounting hole 122.

In this embodiment, by providing the temperature-sensing inner housing 221 to further protect the temperature-sensing probe 222, the temperature-sensing probe 222 can be prevented from being affected by oil smoke and the like, thereby ensuring the accuracy of the temperature-sensing probe 222. The limit flange 2212 cooperates with the through hole 111 to limit the temperature sensing inner shell 221 so as to ensure the position accuracy of the temperature sensing probe assembly 22.
