[0035] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0036] This embodiment provides a kitchen appliance that can be used for cooking food. An integrated stove is a kitchen appliance that integrates a range hood, a cooker, a steamer, an oven, and a disinfection cabinet. With the improvement of people's living standards, integrated stoves have gradually become an indispensable kitchen appliance. The kitchen appliance in this embodiment is described by taking an integrated stove as an example.

[0037] The integrated stove includes a machine head, an air collecting box and a check valve, and the machine head is provided with an air intake port. Figure 1 As shown, the check valve 2 is arranged on one side of the air collecting box 1, the air collecting box 1 is connected to the machine head and the check valve 2, the other end of the check valve 2 is connected to the smoke pipe, and a smoke exhaust component is arranged in the air collecting box 1, the smoke exhaust component includes a volute and a fan arranged in the volute, and negative pressure can be formed in the air collecting box 1 when the fan rotates. The fumes generated by cooking food can enter the machine head through the air intake port, and are discharged to the outside after passing through the air collecting box 1, the volute, the check valve 2 and the smoke pipe in turn, thereby ensuring a cleaner cooking environment indoors.

[0038] In order to accurately control the speed of the fan, an oil fume sensor is needed to detect the oil fume particles in the air collecting box 1 or the check valve 2, and automatically control the air volume of the fan according to the concentration of the oil fume particles detected by the oil fume sensor.

[0039] like Figure 1 and Figure 2As shown, in order to achieve the above-mentioned purpose, the integrated stove also includes a connecting pipe 3 and a bracket for an oil fume sensor. The bracket 4 is fixedly arranged on the outside of the air collecting box 1. The bracket 4 is fixedly arranged with an oil fume sensor 100. One end of the connecting pipe 3 is connected to the oil fume sensor 100 in the bracket 4, and the other end of the connecting pipe 3 is passed through the check valve 2 and extends into the check valve 2.

[0040] The oil fume sensor 100 is provided with a through sampling channel, and the connecting pipe 3 is connected to the sampling channel. When the oil fume enters the sampling channel along the connecting pipe 3, the oil fume sensor 100 can detect the concentration of the oil fume particles. However, the existing bracket 4 mostly fixes the oil fume sensor 100 by a buckle 422. When the oil fume sensor 100 needs to be disassembled, the buckle 422 needs to be pried open by force, which is difficult to operate and the bracket 4 is easily damaged due to excessive force.

[0041] To solve the above problems, this embodiment provides a bracket for a fume sensor, such as Figure 2 to Figure 4 As shown, the bracket 4 includes a fixing portion 41 and a clamping assembly 42. The fixing portion 41 is provided with a fixing groove 411. The oil smoke sensor 100 is partially arranged in the fixing groove 411. The clamping assembly 42 includes two clamping plates 421. The thickness of the two clamping plates 421 gradually decreases in the direction away from the fixing portion 41. The two clamping plates 421 are arranged on two opposite side walls of the fixing groove 411. The oil smoke sensor 100 is located between the two clamping plates 421 and is clamped and fixed by the two clamping plates 421.

[0042] In the bracket 4, the fixing groove 411 of the fixing part 41 is used to accommodate the oil smoke sensor 100, ensuring the stability of the position of the oil smoke sensor 100. The two clamping plates 421 of the clamping assembly 42 can clamp and clamp the oil smoke sensor 100 from the opposite sides of the oil smoke sensor 100, thereby fixing the oil smoke sensor 100. Since the thickness of the clamping plate 421 gradually decreases in the direction away from the fixing part 41, the strength of the clamping plate 421 also gradually decreases, which makes it easy for the operator to open the clamping plate 421 and take out the oil smoke sensor 100.

[0043] The bracket of the oil smoke sensor makes it easy for operators to disassemble the oil smoke sensor 100 , thereby avoiding damage to the bracket 4 .

[0044] like Figure 2 to Figure 4 As shown, a plurality of buckles 422 are protruding from the side wall of the clamping plate 421 facing the other clamping plate 421. The buckles 422 of the two clamping plates 421 are arranged opposite to each other. When the oil smoke sensor 100 is inserted between the two clamping plates 421 and pressed downward into the fixing groove 411, the buckles 422 of the two clamping plates 421 can clamp the oil smoke sensor 100, thereby fixing the oil smoke sensor 100 in the fixing groove 411.

[0045] like Figure 4 As shown, the distance between the two clamping plates 421 gradually increases in the direction away from the fixing portion 41. In other words, the opposite side walls of the two clamping plates 421 are inclined outward in the direction away from the fixing portion 41. The advantage of this structure is that there is a gap between the top of the clamping plate 421 and the oil smoke sensor 100, which makes it easy for operators to bend the clamping plate 421 to remove the oil smoke sensor 100.

[0046] like Figure 4 As shown, the fixing part 41 includes a front plate 412 and a rear plate 413 which are arranged opposite to each other, the rear plate 413 is provided with a connecting column 414, the connecting column 414 is provided with a first connecting port 415, the front plate 412 is provided with a second connecting port 416, the first connecting port 415 is connected to one end of the sampling channel, and the second connecting port 416 is connected to the other end of the sampling channel. A connecting hole is provided on the side wall of the gas collecting box 1, and the function of the connecting column 414 is that when the bracket 4 is arranged on the outside of the gas collecting box 1, the connecting column 414 can be inserted into the connecting hole, which can not only play a positioning role for the bracket 4, but also can generate negative pressure in the sampling channel through the gas flow in the gas collecting box 1, thereby promoting the oil smoke in the check valve 2 to enter the sampling channel through the connecting pipe 3.

[0047] In order to allow the oil smoke to enter the sampling channel, the fixing part 41 includes two side plates 417 arranged at intervals. The side wall of the oil smoke sensor 100 is provided with an air intake pipe 101, which is connected to the sampling channel. When the gas flow in the gas collecting box 1 generates a negative pressure in the sampling channel, the clean air outside the external gas collecting box 1 will enter the sampling channel through the air intake pipe 101 and mix with the oil smoke, thereby reducing the oil smoke concentration to the sensitive range of the oil smoke sensor 100, thereby improving the detection accuracy. Then, the concentration of the oil smoke particles in the check valve 2 can be obtained by conversion. Moreover, the setting of the air intake pipe 101 can also reduce the negative pressure in the sampling channel, thereby reducing the gas flow rate in the sampling channel, which can also improve the detection accuracy.

[0048] like Figure 2 As shown, when the oil fume sensor 100 is arranged in the fixing groove 411, the air intake pipe 101 abuts against the top surface of the side plate 417. At this time, the side plate 417 and the buckle 422 can respectively provide upward and downward forces to the oil fume sensor 100, and cooperate with the inner wall of the fixing groove 411 to ensure the stability of the oil fume sensor 100, avoid the vibration of the air collecting box 1 caused by the rotation of the fan, and cause the position of the oil fume sensor 100 to change, thereby reducing the detection error.

[0049] Furthermore, the two opposite side walls of the oil fume sensor 100 are both provided with the air inlet pipe 101, and each air inlet pipe 101 abuts against the top surface of one side wall. The two side walls abut against the two air inlet pipes 101, so that the upward force of the fixing part 41 on the oil fume sensor 100 can be evenly distributed, further improving the stability of the oil fume sensor 100.

[0050] In this embodiment, the first connection port 415 is arranged opposite to the second connection port 416. At this time, the sampling channel extends in a straight line, and the gas inside will not slow down due to the change of direction when flowing, so the gas flow rate in the sampling channel is stable, thereby improving the detection accuracy.

[0051] like Figure 2 to Figure 4 As shown, the front plate 412 is provided with a connection joint 418, and a plurality of clamping rings 4181 are provided at intervals along the axial direction on the outer periphery of the connection joint 418, and the second connection port 416 is opened at the connection joint 418. The front plate 412 is provided with the connection joint 418, so that the connection pipe 3 is connected to the second connection port 416 of the front plate 412, thereby improving the reliability of the oil smoke sensor 100 during detection.

[0052] Furthermore, the outer diameter of the clamping ring 4181 gradually decreases in the direction away from the fixing portion 41. In other words, the side away from the front plate 412 is inclined, which, on the one hand, facilitates the sleeve of the connecting pipe 3 on the outer periphery of the connecting joint 418, and on the other hand, can reduce the thickness of the outer periphery of the clamping ring 4181, so that the clamping ring 4181 can be embedded in the inner wall of the connecting pipe 3, and the embedding depth is deeper, which improves the reliability of the connection between the connecting joint 418 and the connecting pipe 3, and also improves the sealing performance.

[0053] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
