As shown in fig. 1, the present embodiment provides a range hood 100 and a kitchen ware system. The kitchen ware system comprises a range hood 100 and a kitchen range 200, wherein the range hood 100 is arranged above the kitchen range 200, and the range hood 100 is used for sucking oil smoke, mist and the like generated in the working process of the kitchen range 200. In this embodiment, as shown in fig. 1, the range hood 100 and the cooker 200 are separate structures, and in other embodiments, the range hood 100 and the cooker 200 may also be connected into a whole. Specifically, as shown in fig. 1 and 6, the range hood 100 is installed on a vertical wall surface 300, the range 200 is horizontally arranged, the range 200 includes a horizontally arranged table top 202 and two burners 201 arranged on the table top 202, the two burners 201 are distributed along the left and right direction and are symmetrically arranged, that is, the range 200 has a vertical plane 203 which is perpendicular to the table top 202 and the vertical wall surface 300 and is located between the two burners 201.

Specifically, the range hood 100 includes a frame 1, an operation button, an air duct, a fan, and a control module. The user is through operating the operation button for control module control fan adjustment operating power inhales the oil smoke from the entrance in wind channel, and discharges to outdoor from the exit in wind channel. In this embodiment, as shown in fig. 1, the rack 1 includes a rack main body 11, a panel 12 is disposed on a front side (i.e., a side facing a user) of the rack main body 11, and the panel 12 may be made of glass or sheet metal, so as to be beautiful and convenient to clean.

Preferably, as shown in fig. 2, the range hood 100 further includes a temperature sensing module 2, and the temperature sensing module 2 is electrically connected to the control module. The temperature sensing module 2 is used for detecting the temperature conditions of the two furnace ends 201, so that the control module can correspondingly adjust the working state of the fan according to the temperature detection structure, namely, the intelligent control of the running power of the range hood 100 is realized, and the use experience of a user is improved. As shown in fig. 1 and fig. 2, the temperature sensing module 2 is installed on the panel 12 and located inside the panel 12, that is, the temperature sensing module 2 is not exposed outside the range hood 100, so that the range hood 100 is more beautiful. The panel 12 is provided with an opening 121, and a signal sent or received by the temperature sensing module 2 passes through the opening 121, so as to detect the temperature at the burner 201. It is understood that, in other embodiments, the temperature sensing module 2 may be mounted on the outer side of the panel 12, or partially located on the inner side of the panel 12 and partially located on the outer side of the panel 12, which is not limited herein.

As shown in fig. 3 and 4, the temperature sensing module 2 includes a housing 22, a detection probe 21, a second circuit board 25, and a first wire assembly 26. Wherein the housing 22 includes a casing 221 and a cover 222, the casing 221 forms a receiving cavity having an opening, and the cover 222 covers the casing 221 and covers the opening. Detecting probe 21 and second circuit board 25 all set up and are holding the intracavity, and detecting probe 21 is connected with second circuit board 25 electricity, and first wire assembly 26 one end stretches into and holds the intracavity and be connected with second circuit board 25 electricity, and the other end is connected with the control module of lampblack absorber 100. The temperature sensing module 2 constitutes an integral structure, so that independent maintenance and replacement are convenient to carry out, and the shell 22 can protect the detection probe 21 and the second circuit board 25, so that the service life of the temperature sensing module 2 is prolonged.

As shown in fig. 4, the casing 221 is further provided with a light-transmitting opening 223 communicated with the accommodating cavity, and a signal sent or received by the detection probe 21 passes through the light-transmitting opening 223, so as to detect the temperature outside the casing 22. In this embodiment, the casing 221 is provided with a light-transmitting opening 223, and signals transmitted or received by the two detection probes 21 pass through the same light-transmitting opening 223. As shown in fig. 4, the temperature sensing module 2 further includes a filter assembly, which is installed at the light-transmitting opening 223, specifically, the filter assembly includes a filter 23, the filter 23 can be a silicon wafer, the silicon wafer can filter out stray light except infrared rays, and it can be ensured that the radiation energy entering the detection probe 21 is only infrared radiation energy, thereby improving the measurement accuracy of the red temperature detection mechanism.

The detection probe 21 detects temperature data and sends the temperature data to the second circuit board 25, the second circuit board 25 sends a corresponding control instruction to the control module according to the received temperature data, and the control module of the range hood 100 correspondingly adjusts the working mode of the fan after receiving the control instruction of the detection probe 21, so that automatic adjustment of the range hood 100 in a lampblack suction mode is realized, and the use experience of a user is improved. Because the detection probe 21 and the second circuit board 25 are both arranged in the shell 22, the communication distance between the detection probe 21 and the second circuit board 25 is short, so that the second circuit board 25 can quickly receive the temperature data detected by the detection probe 21, and in addition, the temperature data cannot be distorted due to the communication path end. Because the control instruction sent by the second circuit board 25 to the control module of the range hood 100 is carried out in a simple binary form, the control instruction is less influenced by a longer communication path, and therefore, the accurate control of the range hood 100 cannot be influenced. The detection probe 21 and the second circuit board 25 are electrically connected by a second wire assembly. Wherein the first wire assembly 26 and the second wire assembly each include a power wire, a ground wire, and a communication wire for signal transmission. The type of the detection probe 21 is not limited in this embodiment, and may be, for example, an active infrared temperature measurement sensor or a passive infrared temperature measurement sensor. The active infrared temperature measurement sensor can emit infrared rays, the infrared rays are reflected after contacting the object to be measured and are received by the active infrared temperature measurement sensor again, and the temperature of the object to be measured is measured; the temperature measurement principle of the passive infrared temperature measurement sensor is as follows: when the temperature of the object is higher than thermodynamic zero, infrared rays can radiate to the periphery, and the passive infrared temperature measurement sensor detects the infrared radiation energy of the object, so that the temperature of the object to be detected is detected. In addition to the above two types, any infrared temperature measuring sensor capable of realizing non-contact measurement of the temperature of an object to be measured is within the protection scope of the technical scheme of the invention. When the detection probe 21 is an active infrared temperature measurement sensor, infrared rays emitted by the detection probe 21 pass through the light-transmitting opening 223 and then are transmitted to the outer side of the range hood 100 through the opening 121, and light rays reflected after the infrared rays contact an object pass through the opening 121 on the panel 12 and then are received by the detection probe 21 through the light-transmitting opening 223. For the detection probe 21 being an active infrared temperature measurement sensor, infrared rays radiated by the external cooker 200 or the table 202 pass through the opening 121 on the panel 12 and then pass through the light-transmitting opening 223 to be received by the detection probe 21, so that the detection probe 21 realizes temperature detection.

As shown in fig. 1, 3 and 4, the temperature sensing module 2 includes two detecting probes 21, a coverage area of the detecting probes 21 for sending or receiving signals is conical, and a central axis L of the coverage area of the signals sent or received by the two detecting probes 21 is disposed at an included angle, so as to detect temperature states of different areas respectively. As shown in fig. 4, the inspection probe 21 includes a first circuit board 211 and a signal transceiving terminal 212 provided on one side of the first circuit board 211, and the first circuit board 211 and the second circuit board 25 are electrically connected by a second wire assembly. The signal transceiving ends 212 are used for receiving or sending out the signal transceiving ends 212 of the optical path signals, the signal transceiving ends 212 of the two detecting probes 21 are symmetrically arranged about the middle vertical plane 203, and the detecting probes 21 respectively detect the temperature at the corresponding furnace ends 201. As shown in fig. 5 and 6, the height from the center of the signal transceiving end 212 of the detecting probe 21 to the table top 202 of the kitchen range 200 is H, H is greater than or equal to 400mm and less than or equal to 600mm, the included angle between the projection of the central axis L of the coverage area of the detecting probe 21 on the vertical wall surface 300 and the vertical direction Z is α, the included angle between the projection of the central axis L on the vertical plane 203 and the vertical direction Z is β, wherein α is greater than or equal to 20 ° and less than or equal to 40 °, and β is greater than or equal to 10 ° and less than or equal to 30 °. Through the matching of the above positional relationships, the central axis of the coverage area of each detection probe 21 for sending or receiving signals falls on the center of the corresponding burner 201 as much as possible, and further the coverage area of the detection probes 21 for sending or receiving signals covers the cookware on the corresponding burner 201 as much as possible, so that the reliability of the temperature detection result is ensured, and the range hood 100 can be conveniently adjusted more appropriately according to the detection result of the temperature sensing module 2.

As shown in fig. 6, in this embodiment, the inlet of the air duct is disposed above the panel 12, the panel 12 is disposed obliquely downward, the temperature sensing module 2 is attached to the inner surface of the panel 12, and the included angle between the panel 12 and the vertical wall surface 300 is γ, which is greater than or equal to 30 ° and less than or equal to 50 °. On one hand, the panel 12 and the vertical wall surface 300 can be prevented from having an excessively large included angle, and the panel 12 and the cookware on the burner 201 are prevented from interfering with each other in position; on the other hand, when the included angle between the panel 12 and the vertical wall surface 300 is too small, the projection area of the inlet of the air duct on the horizontally arranged cooker 200 is reduced, so that the oil smoke extraction effect is influenced.

In this embodiment, as shown in fig. 4 and 7, the light paths transmitted or received by the two detection probes 21 pass through the same filter assembly, so that the number of filter assemblies, that is, the number of filters 23, can be reduced, and the structure of the temperature sensing module 2 can be simplified. The intersection position of the central axes L of the signals (i.e., light paths) respectively transmitted or received by the two detection probes 21 is located on one side of the detection probes 21 close to the light-transmitting opening 223, so that the sizes of the light-transmitting opening 223 and the light-filtering component can be reduced, and the structure of the whole temperature sensing module 2 is more compact. In addition, the size of the opening hole 121 on the panel 12 is also reduced, thereby improving the aesthetic appearance of the range hood 100.

As shown in fig. 3, 4, 7 and 8, the temperature sensing module 2 further includes an inner support 24, and the inner support 24 can be installed into the accommodating cavity from the opening. The inspection probe 21 and the second circuit board 25 are mounted on the inner support 24, respectively. When the temperature sensing module 2 is assembled, the second circuit board 25 and the detection probe 21 can be respectively fixed on the inner supporting piece 24, and then the inner supporting piece 24 is integrally installed in the shell 22, so that the workload of installation operation in the shell 22 is reduced, and the assembly convenience and the assembly efficiency of the temperature sensing module 2 are improved; on the other hand, the limit references of the two detection probes 21 are the same inner supporting member 24, so that the phase position precision between the two detection probes 21 is ensured, and the accuracy of the detection result is further ensured.

Alternatively, as shown in fig. 3 and 8, the inner support 24 is provided with a slot 244, and the second circuit board 25 is inserted into the slot 244 and is fixed on the inner support 24. Specifically, the inner supporting member 24 is provided with two slots 244, the two slots 244 are opposite and spaced, and two ends of the second circuit board 25 are respectively inserted into the two slots 244. A space is formed between the two slots 244 to facilitate heat dissipation of the components on the second circuit board 25, and to prevent collision between the components on the second circuit board 25 and the inner support 24 when the second circuit board 25 is mounted.

As shown in fig. 2, since the housing 221 of the temperature sensing module 2 is in contact with the panel 12, the bottom plate of the housing cavity is disposed parallel to the panel 12. As shown in fig. 3, 7 and 8, the inner support 24 includes a support surface 241 and two limiting surfaces 242, and the support surface 241 abuts against the bottom plate of the accommodating cavity, so that the inner support 24 is parallel to the panel 12. Because the inner support 24 is fully retained within the receiving cavity, the relative positional and angular relationships between the inner support 24 and the panel 12 are determined. The limiting surface 242 and the supporting surface 241 form an included angle, the supporting surface 241 is provided with an optical path channel 243, the first circuit board 211 is abutted against the limiting surface 242 and fixed on the limiting surface 242, and the signal transceiving end 212 is accommodated in the optical path channel 243. The optical path channel 243 can avoid the optical path signal transmitted or received by the signal transceiving end 212, so as to ensure smooth signal transceiving. Due to the abutting and fixing of the first circuit board 211 and the limiting surface 242, the angular relationship between the first circuit board 211 and the signal transceiving end 212 thereon and the inner support 24 is determined, and further the relative angle and the position relationship between the signal transceiving end 212 and the panel 12 are determined. That is, the definition of the inclination angle and the position of the signal transceiving ends 212 of the two probes 21 is realized by providing the inner support 24, so that the angle of the central axis L of the signal transceiving ends 212 for receiving or sending out signals conforms to the above-described angular relationship.

As shown in fig. 2, the temperature sensing module 2 is fixed to the inner side of the panel 12 by the mounting bracket 3. Since the panel 12 is thin, it is inconvenient to process installation structures such as grooves and holes. The mounting bracket 3 is adhesively attached to the panel 12. Specifically, as shown in fig. 9 and 10, the mounting bracket 3 includes a connecting portion 31 disposed parallel to the inner surface of the chassis 1 (i.e., the inner surface of the panel 12), one side of the connecting portion 31 facing the inner surface of the panel 12 is provided with at least two bosses 32, the two bosses 32 are disposed at equal heights, the bosses 32 abut against the inner surface of the panel 12 to form a gap between the connecting portion 31 and the inner surface of the chassis 1, and a glue layer 4 is formed in the gap, so that the mounting bracket 3 is connected to the panel 12. Alternatively, the manner of forming the glue layer 4 may be casting. By arranging the boss 32, the connecting portion 31 and the panel 12 are kept in a parallel state, and the accuracy of the installation posture of the whole installation bracket 3 is ensured. In addition, the thickness of the gap formed between the connecting part 31 and the panel 12 is consistent, so that the thickness of the poured glue at each position of the connecting part 31 is uniform, and the mounting bracket 3 is stably and reliably connected. Optionally, in this embodiment, four bosses 32 are provided on the connecting plate, and in other embodiments, the number of the bosses 32 and the distribution positions on the connecting plate are not limited. As shown in fig. 9, the connection portion 31 is provided with a glue injection hole 311, so that glue can be injected into the gap between the connection portion 31 and the panel 12 through the glue injection hole 311, thereby improving convenience of glue injection. As shown in fig. 9, since the plurality of glue injection holes 311 are provided in the connecting portion 31 and the plurality of glue injection holes 311 are uniformly distributed in the connecting portion 31, glue can be injected into the gap from each of the plurality of glue injection holes 311, thereby improving the uniformity of glue distribution in the gap.

As shown in fig. 9, a through hole 2212 is provided on the temperature sensing module 2, a mounting hole 331 is provided on the mounting bracket 3, the range hood 100 further includes a fixing member 5, and the fixing member 5 sequentially penetrates through the through hole 2212 and the mounting hole 331, so as to install the temperature sensing module 2 on the mounting bracket 3. Specifically, as shown in fig. 9, a mounting plate 2211 is disposed on the outer side of the housing 221 of the temperature sensing module 2, a through hole 2212 is disposed on the mounting plate 2211, the mounting bracket 3 includes a support portion 33, the support portion 33 is disposed perpendicular to the connecting portion 31, a mounting hole 331 is disposed on the support portion 33, the fixing element 5 is a bolt, the mounting hole 331 is a threaded hole, and the fixing element 5 penetrates through the through hole 2212 and is in threaded connection with the threaded hole.

In this embodiment, as shown in fig. 10, the axis of the through hole 2212 is inclined with respect to the axis of the mounting hole 331 so that the temperature sensing module 2 is in contact with the inner surface of the chassis 1. Specifically, in the top-to-bottom direction, the axis of the through hole 2212 is disposed obliquely to the side away from the panel 12. When the fixing member 5 is installed from top to bottom, a force is applied to the mounting plate 2211 to make it lean against the panel 12, so that the entire temperature sensing module 2 is pressed against the panel 12. Therefore, the temperature sensing module 2 and the panel 12 can be tightly attached to each other, which not only ensures the accuracy of the installation angle of the temperature sensing module 2, but also reduces the gap between the temperature sensing module 2 and the panel 12 as much as possible, thereby avoiding the influence of the oil drop on the silicon wafer to the detection precision of the detection probe 21.
