When the smoke machine is used with the stove, the relative installation position between the stove and the smoke machine in the horizontal direction and / or vertical direction, if the offset amount of the smoke machine relative to the stove in the horizontal direction and / or vertical direction is too large, will also cause the pot to deviate from the detection field of view of the infrared temperature sensor and appear temperature measurement deviation, ultimately affecting the automatic control of the smoke machine, so the installation position of the smoke machine relative to the stove, the offset amount in the horizontal direction and / or vertical direction is also one of the important factors affecting the automatic control of the smoke machine.

[0027] The application will be further described below in conjunction with the drawings and examples. It should be understood that the specific examples described herein are intended to be illustrative only and are not intended to limit the scope of the application. In addition, it should be noted that only the parts related to the application are shown in the drawings and not all the structures.

[0028] Figure 1 is a structural schematic view of an oil fume purification device and a cooking appliance provided by an embodiment of the application, as shown in the figure, the oil fume purification device comprises a smoke collecting hood 10 and an infrared temperature sensor 20; the smoke collecting hood 10 is used for being installed above the cooking appliance 30; the infrared temperature sensor 20 is arranged on the smoke collecting hood 10 and faces a burner 31 of the cooking appliance 30 and is arranged towards the burner 31; a field of view detection area of the infrared temperature sensor 20 is aligned with the burner 31 area and is used for detecting the temperature near the corresponding burner 31 area. Figure 1

[0029] ​Specifically, the oil fume purification device includes a smoke collecting hood 10 and an infrared temperature sensor 20. The smoke collecting hood 10 can collect oil fume gas in the environment to purify the environment, and the infrared temperature sensor 20 can detect the temperature of the corresponding area. During the installation of the oil fume purification device, the smoke collecting hood 10 needs to be installed above the cooking appliance 30, the infrared temperature sensor 20 is arranged on the smoke collecting hood 10 towards one side of the burner 31 of the cooking appliance 30, and the infrared temperature sensor 20 is arranged towards the burner 31 of the cooking appliance 30, and the field of view detection area of the infrared temperature sensor 20 is aligned with the area of the burner 31 of the cooking appliance 30, and the field of view detection area of the infrared temperature sensor 20 is located within the range of the area of the burner 31 of the cooking appliance 30, further ensuring the detection accuracy of the temperature of the infrared temperature sensor 20. For example, the field of view center line 21 of the field of view detection area of the infrared temperature sensor 20 can pass through the position of the center point of the area of the burner 31 of the cooking appliance 30. In addition, the present embodiment does not specifically require and specially limit the one-to-one correspondence relationship between the infrared temperature sensor 20 and the burner 31. For example, the infrared temperature sensor 20 and the burner 31 can be in a one-to-one correspondence relationship, that is, one infrared temperature sensor 20 can be arranged corresponding to one burner 31 below the oil fume purification device. In this way, the infrared temperature sensor 20 can detect the temperature near the corresponding burner 31 area (which usually corresponds to the area inside the cooking pot 40), and at this time, the detection accuracy of the temperature of the infrared temperature sensor 20 is higher, so that the temperature inside the cooking pot 40 can be accurately detected to determine the cooking stage based on the corresponding temperature, so as to control the oil fume purification device to work in the appropriate gear and mode.

[0030] Figure 2 is a flowchart of an installation method of an oil fume purification device provided by an embodiment of the present application, as shown in the figure, the installation method comprises: Figure 2

[0031] S110, in response to the determined model of the oil fume purification device to be installed, searching for a corresponding preset installation specification; wherein the installation specification is used to indicate the reference installation position of the oil fume purification device and the maximum offset amount allowed by the oil fume purification device relative to the reference installation position.

[0032] ​The type of the oil fume purification equipment and the corresponding installation specification can be a preset and known mapping relationship, that is, for a certain type of oil fume purification equipment, there is a preset installation specification corresponding to the installation of the oil fume purification equipment. Specifically, during the installation of the oil fume purification equipment, the type of the oil fume purification equipment to be installed can be obtained first, and then according to the determined type of the oil fume purification equipment to be installed, the installation of the oil fume purification equipment is searched for the preset installation specification. For example, the type of the oil fume purification equipment can be attached to the surface of the oil fume purification equipment, so as to facilitate the relevant installation personnel to quickly obtain. For example, the relevant installation personnel can find the preset installation specification corresponding to the oil fume purification equipment to be installed by checking the product installation instruction of the preset installation specification table. The preset installation specification table can be understood as a preset installation instruction document. It can be understood that different types of oil fume purification equipment correspond to different installation requirements, that is, different installation specifications. The user or installer of the oil fume purification equipment can determine the reference installation position of the oil fume purification equipment and the maximum offset of the oil fume purification equipment relative to the reference installation position by checking the corresponding preset installation specification, so as to better guide and carry out the installation process of the cooking utensil or the oil fume purification equipment. Alternatively, for example, the relevant installation personnel can find the preset installation specification corresponding to the oil fume purification equipment to be installed through the preset installation specification software. The preset installation specification software can be understood as a preset installation demonstration program. The form of the installation demonstration program includes but is not limited to text, picture, audio and video. It can be understood that different types of oil fume purification equipment correspond to different installation requirements, that is, different installation specifications. The user or installer of the oil fume purification equipment can determine the reference installation position of the oil fume purification equipment and the maximum offset of the oil fume purification equipment relative to the reference installation position by checking the corresponding preset installation specification, so as to better guide and carry out the installation process of the cooking utensil or the oil fume purification equipment.

[0033] The preset installation specification is used to indicate the reference installation position of the oil fume purification device and the maximum offset amount of the oil fume purification device relative to the reference installation position. It can be understood that in the finished oil fume purification device, the position of the infrared temperature sensor 20 on the smoke hood 10 is determined and known, and the field of view angle of the infrared temperature sensor 20 is also determined and known, so that based on the preferred condition that the center of the field of view detection area of the infrared temperature sensor 20 is aligned with the center of the burner 31 area of the cooking appliance 30, the reference installation position of the oil fume purification device can be determined, that is, the reference installation position of the oil fume purification device is determined and known. Based on the reference installation position of the oil fume purification device, the oil fume purification device should have a determined installation offset range, that is, the maximum offset amount of the oil fume purification device relative to the reference installation position, which can allow the field of view detection area of the infrared temperature sensor 20 to be located within the burner 31 area of the cooking appliance 30. In this way, the reference installation position of the oil fume purification device and the maximum offset amount of the oil fume purification device relative to the reference installation position can be corresponded to the preset installation specification, and the installation position of the oil fume purification device is prompted to the relevant installation personnel in the form of the preset installation specification. In an easier to understand manner, the relevant installation personnel can install the oil fume purification device at the corresponding reference installation position based on the preset installation specification, or the relevant installation personnel can install the oil fume purification device within the maximum offset amount of the corresponding reference installation position based on the preset installation specification. For example, the reference installation position of the oil fume purification device indicated by the preset installation specification can include a height of 1.8 meters, and the maximum offset amount of the reference installation position can include an offset range of a height of 0.1 meters, so that the relevant installation personnel can install the oil fume purification device at any height position within the range interval of a height of 1.7 meters to 1.9 meters based on the preset installation specification, and similarly, the installation range interval of the oil fume purification device relative to the cooking appliance in the horizontal direction can also be obtained based on the preset installation specification.

[0034] S120, according to the installation specification, the oil fume purification device is installed on the installation wall surface to align the field of view detection area of the infrared temperature sensor with the burner area, and the field of view detection area is located within the range of the burner area.

[0035] Specifically, the installation position of the oil fume purification equipment on the corresponding installation wall surface can be determined according to the corresponding preset installation specification of the oil fume purification equipment to be installed, so as to install the oil fume purification equipment on the installation wall surface. For example, the installation wall surface can be the wall surface of the kitchen. In the preset installation specification, the installation steps can be described, and a lookup table of reference horizontal installation position of the oil fume purification equipment to be installed, maximum horizontal offset relative to the reference horizontal installation position, reference installation height, maximum height offset relative to the reference installation height, and the like can be attached for reference by the relevant installer during installation. After the installation position is determined, the oil fume purification equipment is installed, and after the installation is completed, the infrared temperature sensor 20 is arranged towards the burner 31 of the cooking appliance 30, so that the field of view detection area of the infrared temperature sensor 20 is aligned with the burner 31 area of the cooking appliance 30, and the field of view detection area of the infrared temperature sensor 20 is located within the range of the burner 31 area of the cooking appliance 30, further ensuring the detection accuracy of the temperature of the infrared temperature sensor 20. In this way, the relevant installer can determine whether the installation position of the oil fume purification equipment can ensure the temperature measurement accuracy of the infrared temperature sensor without relying on personal installation experience or cumbersome size measurement, and the relevant installer only needs to determine the corresponding preset installation specification of the oil fume purification equipment according to the lookup table, which can effectively simplify the installation steps of the relevant installer and ensure that the installation position of the oil fume purification equipment is conducive to the temperature measurement accuracy of the infrared temperature sensor 20.

[0036] The technical solution in the embodiment of the present application, the installation method can determine the installation position of the oil fume purification equipment relative to the cooking appliance according to the determined model of the oil fume purification equipment to be installed, which conforms to the preset installation specification, facilitates the installation operation process of the relevant installer, avoids the problem that blind installation or unified installation standard affects the temperature measurement accuracy of the infrared temperature sensor, achieves humanized installation, meets the installation needs of users, conforms to the space design of the actual application scene and installation scene of the user, and after the installation is completed, the field of view detection area of the infrared temperature sensor is aligned with the burner area, and the field of view detection area of the infrared temperature sensor is located within the range of the burner area, which effectively improves the temperature measurement accuracy of the infrared temperature sensor, and further improves the automatic control effect of the oil fume purification equipment, and ensures good cooking experience and use comfort of the user.

[0037] Optionally, in response to the determined model of the oil fume purification equipment to be installed, the corresponding preset installation specification is searched, including: in response to the information code on the oil fume purification equipment to be installed scanned and acquired by using the preset software program on the intelligent terminal, the corresponding preset installation specification is searched.

[0038] The type of the oil fume purification device and the information code on the oil fume purification device can have a preset mapping relationship. According to the information code on the oil fume purification device, the type of the oil fume purification device can be determined. That is, for a determined type of the oil fume purification device, there is a corresponding information code. Exemplarily, the information code can be a symbol (number, English, etc.) code, a two-dimensional code, a bar code, etc. In addition, the type of the oil fume purification device and the corresponding installation specification can be a preset and known mapping relationship. That is, for a determined type of the oil fume purification device, there is a preset installation specification corresponding to the installation of the oil fume purification device. In this way, for a determined information code on the oil fume purification device, there is a preset installation specification corresponding to the installation of the oil fume purification device. That is, through the information code on the oil fume purification device to be installed, the corresponding preset installation specification of the oil fume purification device can be indirectly found and determined.

[0039] Specifically, the information code on the oil fume purification device to be installed can be scanned and obtained by using a preset software program on the intelligent terminal. The preset software program on the intelligent terminal can be used to find and determine the corresponding preset installation specification of the oil fume purification device. Exemplarily, the intelligent terminal can be a mobile phone, a tablet computer, or the like.

[0040] Optionally, in response to the determined type of the oil fume purification device to be installed, the corresponding preset installation specification is found, including: in response to the determined type of the oil fume purification device to be installed, the installation specification lookup table attached in the installation manual is used to find the installation specification corresponding to the type of the oil fume purification device to be installed; wherein the installation specification lookup table has the reference installation position of the oil fume purification device of different types and the maximum offset allowed with respect to the reference installation position.

[0041] The types of the plurality of oil fume purification devices and the corresponding preset installation specifications thereof can be stored in the installation specification lookup table attached in the same installation manual. Exemplarily, the installation specification lookup table attached in the installation manual can be understood as a preset installation instruction document. Specifically, after the type of the oil fume purification device to be installed is obtained, the installation specification lookup table attached in the installation manual can be used to find and determine the installation specification corresponding to the type of the oil fume purification device to be installed. It can be understood that different types of oil fume purification devices correspond to different installation requirements, that is, different installation specifications. The user or installer of the oil fume purification device can refer to the installation specification lookup table attached in the installation manual to determine the reference installation position of the oil fume purification device and the maximum offset allowed with respect to the reference installation position, so as to better guide and carry out the installation process of the cooking utensil or the oil fume purification device.

[0042] Optionally, in response to the determined model of the oil fume purification equipment to be installed, a corresponding preset installation specification is searched, including: in response to the determined model of the oil fume purification equipment to be installed, the reference installation position corresponding to the model of the oil fume purification equipment to be installed and the maximum offset allowed with respect to the reference installation position are output through the preset software program on the intelligent terminal, and the installation specification is obtained.

[0043] The models of the plurality of oil fume purification equipment and the respective corresponding preset installation specifications can be stored in the preset software program on the same intelligent terminal, that is, the preset software program on the intelligent terminal can have the reference installation positions corresponding to the oil fume purification equipment of different models and the maximum offset allowed with respect to the reference installation positions. Specifically, after the model of the oil fume purification equipment to be installed is obtained, the model of the oil fume purification equipment can be input into the preset software program on the intelligent terminal, the corresponding preset installation specification is searched and processed through the preset software program on the intelligent terminal, and the installation specification corresponding to the model of the oil fume purification equipment to be installed is output. For example, the installation specification can include the output reference installation position corresponding to the model of the oil fume purification equipment to be installed and the maximum offset allowed with respect to the reference installation position. It can be understood that different installation requirements of oil fume purification equipment of different models, that is, different installation specifications, the user or installer of the oil fume purification equipment can determine the reference installation position of the oil fume purification equipment and the maximum offset allowed with respect to the reference installation position of the oil fume purification equipment by consulting the preset software program on the intelligent terminal, so as to better guide and carry out the installation process of the cooking utensil or the oil fume purification equipment.

[0044] In addition, it can be understood that the installation specification can also be obtained in other ways, and those skilled in the art can make reasonable selection and adjustment according to the needs, which will not be illustrated one by one in the embodiment.

[0045] In another specific embodiment, optionally, in response to the determined model of the oil fume purification equipment to be installed, a corresponding preset installation specification is searched, including: in response to the determined model of the oil fume purification equipment to be installed, a corresponding preset first installation specification is searched; wherein the first installation specification is used to indicate the reference horizontal installation position of the oil fume purification equipment and the maximum horizontal offset allowed with respect to the reference horizontal installation position of the oil fume purification equipment, and the maximum horizontal offset is the offset allowed by the oil fume purification equipment with respect to the cooking utensil in any direction parallel to the plane on which the cooking utensil is located.

[0046] First, the first installation specification in the preset installation specification is explained. Figure 3a is a simplified position relationship diagram of a reference horizontal installation position of an oil fume purification equipment provided by the embodiment of the application, as shown inFigure 3a As shown, the reference horizontal installation position of the oil fume purification device indicated by the first installation specification can be understood as the optimal installation position of the oil fume purification device in the horizontal direction relative to the cooking appliance 30, or in other words, the standard relative installation position in the horizontal direction between the cooking appliance 30 and the oil fume purification device. At this time, the field-of-view detection area of the infrared temperature sensor 20 is located within the range of the burner 31 area of the cooking appliance 30, and the field-of-view center line 21 of the field-of-view detection area of the infrared temperature sensor 20 can just pass through the position of the center point O of the burner 31 area of the cooking appliance 30. Exemplarily, the reference horizontal installation position can include a reference distance a (i.e., the length of the line segment OD) between the center point of the burner 31 and the wall surface on which the oil fume purification device is installed, a reference distance b (i.e., the length of the line segment CD) between the infrared temperature sensor 20 and the wall surface on which the oil fume purification device is installed, a reference distance c (i.e., the length of the line segment AB) between the infrared temperature sensor 20 and the tabletop of the cooking appliance 30, a reference offset z (i.e., the length of the line segment BC) of the infrared temperature sensor 20 in the first direction X relative to the center of the corresponding burner 31, and the like. Figure 3b is a simplified position relationship diagram of the maximum horizontal offset of the oil fume purification device relative to the reference horizontal installation position provided by an embodiment of the present application, as shown in Figure 3b As shown, the maximum horizontal offset of the oil fume purification device relative to the reference horizontal installation position indicated by the first installation specification, which is the maximum offset of the oil fume purification device relative to the cooking appliance 30 in any direction parallel to the plane on which the cooking appliance 30 is located, can be understood as the maximum offset in the plane parallel to the plane on which the cooking appliance 30 is located between the reference horizontal installation position of the oil fume purification device and the installation position when finally installed, or in other words, the offset range of the oil fume purification device in the horizontal direction on the basis of the standard relative installation position in the horizontal direction between the cooking appliance 30 and the oil fume purification device. At this time, the field-of-view detection area of the infrared temperature sensor 20 is located at a critical position within the range of the burner 31 area of the cooking appliance 30. Exemplarily, the maximum horizontal offset can include the offset of the oil fume purification device relative to the reference horizontal installation position in the front-rear direction, and the offset of the oil fume purification device relative to the reference horizontal installation position in the left-right direction. It should be noted that, Figure 3a Compared with Figure 3b The same infrared temperature sensor 20 only has an offset in the horizontal direction relative to the cooking appliance 30, and has no offset in the vertical direction.

[0047] Specifically, in response to the determined model of the oil fume purification device to be installed, a corresponding preset first installation specification is searched. In the installation process of the oil fume purification device, the model of the oil fume purification device to be installed can be acquired first, and then, according to the determined model of the oil fume purification device to be installed, a corresponding preset first installation specification for the installation of the oil fume purification device is searched. In this way, the first installation specification can be used to determine the required installation position of the oil fume purification device on the corresponding installation wall surface, and the relevant installation personnel can install the oil fume purification device on the installation wall surface. In this horizontal installation position, the field-of-view detection area of the infrared temperature sensor 20 is aligned with the burner head 31 area of the cooking appliance 30, and the field-of-view detection area of the infrared temperature sensor 20 is located within the range of the burner head 31 area of the cooking appliance 30.

[0048] Figure 4a and Figure 4b are schematic diagrams of the position of the field-of-view detection area of the two infrared temperature sensors and the burner head area of the cooking appliance provided by the embodiments of the present application, as shown in Figure 4a and Figure 4b , the small circles represent the field-of-view detection area of the infrared temperature sensor 20, the large dashed circle represents the position of the burner head 31 area of the cooking appliance 30 corresponding to the reference horizontal installation position of the oil fume purification device, and the large solid circle represents the position of the burner head 31 area of the cooking appliance 30 corresponding to the oil fume purification device with the maximum horizontal offset relative to the reference horizontal installation position. It should be noted that, regardless of the position relationship between the infrared temperature sensor 20 and the burner head 31 of the cooking appliance 30, the height and field-of-view angle of the infrared temperature sensor 20 are fixed at this time, so the size of the field-of-view detection area of the infrared temperature sensor 20 is fixed, for example Figure 4a and Figure 4b , the field-of-view detection area of the infrared temperature sensor 20 is the same.

[0049] Continuing to refer to Figure 4a and Figure 4b , the maximum horizontal offset t can be determined according to the distance between the center point of the field-of-view detection area of the infrared temperature sensor 20 and the center point of the burner head 31 area of the cooking appliance 30, and the field-of-view detection area of the infrared temperature sensor 20 cannot deviate outside the burner head 31 area of the cooking appliance 30. For example Figure 4a , the maximum horizontal offset t = j / 2-f / 2 = (j-f) / 2, and for example Figure 4b , the maximum horizontal offset t = j / 2-f / 2 = (j-f) / 2, where j is the diameter of the burner head 31 area, and f is the diameter of the field-of-view detection area of the infrared temperature sensor 20. In addition, Figure 5 is a schematic diagram of the field-of-view detection area and the field-of-view angle of an infrared temperature sensor provided by an embodiment of the present application, as shown in Figure 5As shown, it can be obviously seen that the shape of the field-of-view detection area of the infrared temperature sensor 20 is similar to a searchlight, which can be understood as a cone. The diameter of the field-of-view detection area of the infrared temperature sensor 20 is f, and the radius of the field-of-view detection area of the infrared temperature sensor 20 is k = f / 2, which is exemplified by taking the line segment MN as one of the diameters of the field-of-view detection area of the infrared temperature sensor 20. The field-of-view angle of the infrared temperature sensor 20 is 2a0, and half of the field-of-view angle of the infrared temperature sensor 20 is a0. It can be obviously obtained that k = d x tan a0. That is, the diameter f of the field-of-view detection area of the infrared temperature sensor can be determined by the field-of-view angle 2a0 of the infrared temperature sensor 20, the length d of the line connecting the infrared temperature sensor 20 and the center of the corresponding burner 31, and then the maximum horizontal offset t is determined. The line connecting the infrared temperature sensor 20 and the center of the corresponding burner 31 is also the field-of-view center line 21 of the field-of-view detection area of the infrared temperature sensor 20. In addition, Figure 4a and Figure 4b As shown in the horizontal position offset condition, if the field-of-view detection area of the infrared temperature sensor 20 offsets to the area outside the burner 31 of the cooking appliance 30, the field-of-view detection area of the infrared temperature sensor 20 will at least partially detect the temperature of the area outside the cooking utensil 40 (such as the temperature of the flame or the tabletop), so that the temperature detected by the infrared temperature sensor 20 cannot truly reflect the actual temperature inside the cooking utensil 40. Of course, Figure 4a and Figure 4b The horizontal position offset condition shown is only an example, and other offsets in the horizontal direction can also be included, which will not be exemplified one by one in the present embodiment.

[0056] The above description of the present embodiment only discusses the corresponding relationship between the infrared temperature sensor 20 and the corresponding burner head 31, but does not describe the number of infrared temperature sensors 20. Alternatively, continuing to refer to Figure 1The two burners 31 are arranged on the cooktop 30, and the two infrared temperature sensors 20 are arranged on the fume hood 10 and correspond to the two burners 31, respectively. In the first direction X, the two infrared temperature sensors 20 are located on the two sides away from each other of the two burners 31, respectively. The first direction X is parallel to the center line of the two burners 31 on the cooktop 30.

The two infrared temperature sensors 20 are arranged close to each other and are located at the middle positions of the two burners 31 in the first direction X. The first direction X is parallel to the center line of the two burners 31 on the cooktop 30.

[0059] Specifically, Figure 6 The oil fume purification equipment shown is a top suction type range hood. The distribution mode of the two infrared temperature sensors 20 in the oil fume purification equipment can be understood as a concentrated topology structure, that is, the left infrared temperature sensor 20 and the right infrared temperature sensor 20 are placed together and are located directly above the center of the cooktop 30 and in the vicinity of the outer side. The field of view detection area of the left infrared temperature sensor 20 is aligned with the left burner 31 area, and the left infrared temperature sensor 20 can perform temperature measurement for the left burner 31 area. The field of view detection area of the right infrared temperature sensor 20 is aligned with the right burner 31 area, and the right infrared temperature sensor 20 can perform temperature measurement for the right burner 31 area.

[0060] Optionally, continuing to refer to Figure 6, the offset z of the infrared temperature sensor 20 along the first direction X relative to the center of the corresponding burner head 31 is determined by the center distance e of the two burner heads 31.

[0061] Specifically, the two infrared temperature sensors 20 are arranged in close proximity and are both located at the middle position of the two burner heads 31 along the first direction X, that is, the offset z of each infrared temperature sensor 20 along the first direction X relative to the center of the corresponding burner head 31 can be approximately considered equal to half of the center distance e of the two burner heads 31, that is, z = e / 2.

[0062] Further, the maximum horizontal offset t is determined based on the following parameters: the field angle 2a0 of the infrared temperature sensor 20; the reference distance a between the center point of the burner head 31 and the wall surface on which the oil fume purification device is installed; the reference distance b between the infrared temperature sensor 20 and the wall surface on which the oil fume purification device is installed; the reference distance c between the infrared temperature sensor 20 and the tabletop of the cooking appliance 30; the spacing e between the centers of the two burner heads 31; and the diameter j of the area of the burner head 31.

[0063] Specifically, continuing to refer to Figure 6 , the infrared temperature sensor 20 can be point A, the vertical projection point of the infrared temperature sensor 20 on the tabletop of the cooking appliance 30 can be point B, the reference distance c between the infrared temperature sensor 20 and the tabletop of the cooking appliance 30 can be line segment AB, and line segment AB can also be understood as the reference installation height of the oil fume purification device.

[0064] The infrared temperature sensor 20 can be point A, the vertical projection point of the infrared temperature sensor 20 on the tabletop of the cooking appliance 30 can be point B, the vertical line of the wall surface on which the oil fume purification device is installed passing through point B has an intersection point D with the wall surface on which the oil fume purification device is installed, that is, line segment BD is perpendicular to the wall surface on which the oil fume purification device is installed. The center point of the burner head 31 can be point O, the vertical line of line segment BD passing through point O has an intersection point C, and line segment OC is perpendicular to line segment BD (or line segment OC is perpendicular to line segment BC, line segment CD). The reference distance b between the infrared temperature sensor 20 and the wall surface on which the oil fume purification device is installed can be line segment BD. The reference distance a between the center point of the burner head 31 and the wall surface on which the oil fume purification device is installed can be line segment CD. The spacing e between the two burner heads 31 can be twice the length of line segment OC, and line segment OC is also the offset z of the infrared temperature sensor 20 along the first direction X relative to the center of the corresponding burner head 31, and line segment OC is equal to half of the center distance e of the two burner heads 31.

[0065] The infrared temperature sensor 20 can be point A, the center point of the burner head 31 can be point O, and the length d of the line connecting the infrared temperature sensor 20 and the center of the corresponding burner head 31 can be line segment AO, and it can be obtained that That is, That is, That is, the maximum horizontal offset t allowed for the oil fume purification equipment relative to the reference horizontal installation position can be determined according to the field of view angle 2a0 of the infrared temperature sensor 20, the reference distance a between the center point of the burner 31 and the wall surface on which the oil fume purification equipment is installed, the reference distance b between the infrared temperature sensor 20 and the wall surface on which the oil fume purification equipment is installed, the reference distance c between the infrared temperature sensor 20 and the tabletop of the cooking appliance 30, the spacing e between the centers of the two burners 31, and the diameter j of the burner 31 region.

[0066] In yet another specific embodiment, the corresponding preset installation specification is searched in response to the determined model of the oil fume purification equipment, including: searching for a corresponding preset second installation specification in response to the determined model of the oil fume purification equipment; wherein the second installation specification is used to indicate a reference installation height of the oil fume purification equipment and a maximum height offset allowed for the oil fume purification equipment relative to the reference installation height, the maximum height offset being an offset allowed for the oil fume purification equipment relative to the cooking appliance in a direction perpendicular to the plane on which the cooking appliance is located.

[0067] First, the second installation specification in the preset installation specification is explained. Figure 7a is a simplified position relationship diagram of a reference installation height of an oil fume purification equipment provided by an embodiment of the present application, as Figure 7a indicated, the reference installation height of the oil fume purification equipment indicated by the second installation specification can be understood as the optimal installation height of the oil fume purification equipment relative to the cooking appliance 30 in the vertical direction, or in other words, the standard relative installation height in the vertical direction between the cooking appliance 30 and the oil fume purification equipment. At this time, the field of view detection region of the infrared temperature sensor 20 is located within the range of the burner 31 region of the cooking appliance 30, and the field of view center line 21 of the field of view detection region of the infrared temperature sensor 20 can just pass through the position of the center point O of the burner 31 region of the cooking appliance 30. Exemplarily, Figure 7a indicated can also be understood as a simplified position relationship diagram when the oil fume purification equipment is in the first installation state, and the reference installation height can include the reference distance c (i.e., the length of the line segment AB) between the infrared temperature sensor 20 and the tabletop of the cooking appliance 30 when the oil fume purification equipment is in the first installation state. Figure 7b is a simplified position relationship diagram of a maximum height offset allowed for an oil fume purification equipment relative to a reference installation height provided by an embodiment of the present application, as Figure 7bAs shown, the maximum height offset of the oil fume purification device indicated by the second installation specification relative to the reference installation height is the maximum offset of the oil fume purification device relative to the stove 30 in the direction perpendicular to the plane on which the stove 30 is located, which can be understood as the maximum offset in the vertical direction between the reference installation height of the oil fume purification device and the installation position in the final installation, or in other words, the offset range of the oil fume purification device in the vertical direction based on the standard relative installation height in the vertical direction between the stove 30 and the oil fume purification device. At this time, the field-of-view detection area of the infrared temperature sensor 20 is located at a critical position within the range of the burner 31 area of the stove 30. Exemplarily, Figure 7b As shown, it can also be understood as a simplified position relationship diagram of the oil fume purification device in the second installation state, Figure 7a As shown, the installation height of the oil fume purification device is Figure 7b As shown, the absolute value of the difference between the installation height of the oil fume purification device is equal to the maximum height offset. It should be noted that, Figure 7a As shown, the installation height of the oil fume purification device is Figure 7b Compared with the first installation specification, the same infrared temperature sensor 20 only has an offset in the vertical direction relative to the stove 30, and has no offset in the horizontal direction.

[0068] Specifically, in response to the determined type of the oil fume purification device to be installed, the corresponding preset second installation specification is searched. During the installation of the oil fume purification device, the type of the oil fume purification device to be installed can be acquired first, and then according to the determined type of the oil fume purification device to be installed, the installation of the oil fume purification device is searched for the corresponding preset second installation specification. In this way, the required installation height of the oil fume purification device on the corresponding installation wall surface can be determined according to the second installation specification, and the relevant installation personnel can install the oil fume purification device on the installation wall surface at the installation height, at which the field-of-view detection area of the infrared temperature sensor 20 is aligned with the burner 31 area of the stove 30, and the field-of-view detection area of the infrared temperature sensor 20 is located within the range of the burner 31 area of the stove 30.

[0069] Figure 8a And Figure 8b are two more position diagrams of the field-of-view detection area of the infrared temperature sensor and the burner area of the stove provided by the embodiments of the present application, as shown in Figure 8a And Figure 8bAs shown in the figure, the largest circle represents the burner 31 area of the cooking appliance 30, the first installation state is that the oil fume purification equipment is installed on the installation wall surface according to the reference installation height, and the circle area with the center point O can be understood as the field of view detection area of the infrared temperature sensor 20 when the oil fume purification equipment is in the first installation state. The second installation state is that the oil fume purification equipment is installed on the installation wall surface according to the installation height with the maximum height offset g relative to the reference installation height, and the circle area with the center point O1 can be understood as the field of view detection area of the infrared temperature sensor 20 when the oil fume purification equipment is in the second installation state. It should be noted that the size of the field of view angle of the infrared temperature sensor 20 will not change with the change of the actual installation height of the oil fume purification equipment, but the size and position of the field of view detection area of the infrared temperature sensor 20 will change with the change of the actual installation height of the oil fume purification equipment, so the range of the field of view detection area of the infrared temperature sensor 20 is not fixed during the installation of the oil fume purification equipment.

[0070] With reference to the above Figure 8a and Figure 8b , the maximum height offset g can be determined according to the distance between the center of the field of view detection area of the infrared temperature sensor 20 with the center point O and the center of the field of view detection area of the infrared temperature sensor 20 with the center point O1, and the field of view detection area of the infrared temperature sensor 20 with the center point O1 cannot deviate out of the burner 31 area of the cooking appliance 30. Figure 8a and Figure 8b It can be understood that Figure 1 the oil fume purification equipment shown in the figure is in the relative installation condition of upward and downward offset relative to the reference installation height, and Figure 8a is taken as an example for illustration, it can be obviously seen that j / 2=k1+L, and similarly, Figure 8b is taken as an example for illustration, it can be obviously seen that j / 2=k1+L, where j is the diameter of the burner 31 area, k1 is the radius of the field of view detection area of the infrared temperature sensor 20 with the center point O1, and L is the offset of the center of the field of view detection area of the infrared temperature sensor 20 when the oil fume purification equipment is in the second installation state relative to the center of the field of view detection area of the infrared temperature sensor 20 when the oil fume purification equipment is in the first installation state, that is, the distance between the center point O1 and the center point O. And, Figure 9 is another schematic view of the field of view detection area and the field of view angle of the infrared temperature sensor provided by the embodiment of the present application, as Figure 9As shown, it can be clearly seen that the shape of the field-of-view detection area of the infrared temperature sensor 20 is similar to a searchlight, which can be understood as a cone. The diameter of the field-of-view detection area of the infrared temperature sensor 20 when the oil fume purification device is in the first installation state is f0, and the radius of the field-of-view detection area of the infrared temperature sensor 20 when the oil fume purification device is in the first installation state is k0=f0 / 2. The diameter of the field-of-view detection area of the infrared temperature sensor 20 when the oil fume purification device is in the second installation state is f1, and the radius of the field-of-view detection area of the infrared temperature sensor 20 when the oil fume purification device is in the second installation state is k1=f1 / 2. The field-of-view angle of the infrared temperature sensor 20 is 2α0, and half of the field-of-view angle of the infrared temperature sensor 20 is α0. The size of the field-of-view angle of the infrared temperature sensor 20 does not change with the change of the radius of the field-of-view detection area of the infrared temperature sensor 20, and the size of the field-of-view angle of the infrared temperature sensor 20 does not change with the change of the length of the line connecting the infrared temperature sensor 20 and the center of the corresponding burner 31. It can be clearly obtained that k0=d0*tanα0 and k1=d1*tanα0. That is, k1 and L can be determined by the field-of-view angle 2α0 of the infrared temperature sensor 20, the length d0 of the line connecting the infrared temperature sensor 20 and the center of the corresponding burner 31 when the oil fume purification device is in the first installation state, and the length d1 of the line connecting the infrared temperature sensor 20 and the center of the corresponding burner 31 when the oil fume purification device is in the second installation state, which is conducive to determining the maximum height offset g. In addition, Figure 8a and Figure 8b As shown in the height position offset condition, if the field-of-view detection area of the infrared temperature sensor 20 deviates to the area outside the burner 31 of the cooking appliance 30, the field-of-view detection area of the infrared temperature sensor 20 will at least partially detect the temperature of the area outside the cooking utensil 40 (such as the temperature of the flame or the table), so that the temperature detected thereby cannot truly reflect the actual temperature inside the utensil 40. Of course, Figure 8a and Figure 8b The relative position offset condition of the center point O and the center point O1 shown is only an example, and other horizontal direction offsets can also be included, which are not exemplified one by one in this embodiment.

[0071] Optionally, the maximum height offset g is determined based on the following parameters: a reference distance a between a center point of the burner head 31 and a wall surface on which the oil fume purification device is installed; a reference distance b between the infrared temperature sensor 20 and the wall surface on which the oil fume purification device is installed; a reference distance c between the infrared temperature sensor 20 and a cooking surface of the cooking appliance 30; a reference offset z of the infrared temperature sensor 20 relative to the center of the corresponding burner head 31 along the first direction X; and a radius k0 of the field-of-view detection area of the infrared temperature sensor 20 when the oil fume purification device is in the first installation state; wherein the first direction X is a direction parallel to the line connecting the centers of the two burner heads 31 on the cooking appliance 30, and the first installation state is a state in which the oil fume purification device is installed on the installation wall surface according to a reference installation height.

[0072] wherein the reference distance a can be understood as the spacing between the center point of the burner head 31 and the installation wall surface in the second direction Y, the reference distance b can be understood as the spacing between the infrared temperature sensor 20 and the installation wall surface in the second direction Y, the reference distance c can be understood as the spacing between the infrared temperature sensor 20 and the cooking surface of the cooking appliance 30 in the third direction Z, and the reference offset z can be understood as the spacing between the infrared temperature sensor 20 and the center of the corresponding burner head 31 in the first direction X.

[0073] Specifically, Figure 1 It can be understood as a structural schematic view when the oil fume purification device is in the first installation state. Continuing to refer to Figure 1 , the infrared temperature sensor 20 can be point A, and the center point of the burner head 31 can be point O, and point O is also the center point of the field-of-view detection area of the infrared temperature sensor 20 when the oil fume purification device is in the first installation state, and the line connecting the center of the infrared temperature sensor 20 and the corresponding burner head 31 when the oil fume purification device is in the first installation state can be line segment AO, and the following can be obtained Further, In addition, it also needs to be explained that the corresponding field-of-view angle of the infrared temperature sensor 20 when the oil fume purification device is in the first installation state is 2a0, and the corresponding field-of-view angle of the infrared temperature sensor 20 when the oil fume purification device is in the second installation state is also 2a0, Figure 9 only exemplary representation k1>k0, corresponding d1>d0, in other embodiments, also can k1<k0, corresponding d1<d0, the present embodiment is not exemplified one by one here.

[0074] Optionally, Figure 10a is Figure 8a The triangular similarity relationship between the field-of-view detection area of the infrared temperature sensor and the burner head area of the cooking appliance is shown in FIG. 4, as Figure 1 , Figure 8a and Figure 10aAs shown, the center point of the stove head 31 can be point O, and point O is also the center point of the field of view detection area of the infrared temperature sensor 20 when the oil fume purification equipment is in the first installation state. The infrared temperature sensor 20 can be point A, the vertical projection point of the infrared temperature sensor 20 on the table top of the stove 30 can be point B, the center point of the field of view detection area of the infrared temperature sensor 20 when the oil fume purification equipment is in the second installation state can be point O1, and the position point corresponding to the installation height of the infrared temperature sensor 20 when the oil fume purification equipment is in the second installation state can be point P. The reference distance a between the center point of the stove head 31 and the wall surface on which the oil fume purification equipment is installed can be line segment OD, the reference distance b between the infrared temperature sensor 20 and the wall surface on which the oil fume purification equipment is installed can be line segment CD, the reference distance c between the infrared temperature sensor 20 and the table top of the stove 30 can be line segment AB, the reference offset z of the infrared temperature sensor 20 along the first direction X relative to the center of the corresponding stove head 31 can be line segment BC, and the maximum height offset g can be line segment AP.

[0075] In addition, triangle OAB can be understood as a schematic diagram of a triangular relationship when the oil fume purification equipment is in the first installation state, and triangle O1PB can be understood as a schematic diagram of a triangular relationship when the oil fume purification equipment is in the second installation state. Figure 10a It can be clearly seen that triangle OAB and triangle O1PB are similar triangles, so line segment AB / line segment PB=line segment AO / line segment PO1. Among them, line segment AB is c, line segment PB is c+g, line segment AO is the length d0 of the line connecting the infrared temperature sensor 20 and the center of the corresponding stove head 31 when the oil fume purification equipment is in the first installation state, and line segment PO1 is the length d1 of the line connecting the infrared temperature sensor 20 and the center of the corresponding stove head 31 when the oil fume purification equipment is in the second installation state. That is, Similarly, line segment AB / line segment PB=line segment OB / line segment O1B. Among them, line segment AB is c, line segment PB is c+g, line segment OB forms a right triangle with line segment BC and line segment OC, line segment BC is z, line segment OC=b-a-line segment OD=b-a, and line segment OB is line segment O1B=line segment OB+line segment OO1, which is the center of the field of view detection area of the infrared temperature sensor 20 when the oil fume purification equipment is in the second installation state, relative to the offset L of the center of the field of view detection area of the infrared temperature sensor 20 when the oil fume purification equipment is in the first installation state. That is,

[0076] Further, j / 2=k1+L, k1=d1*tanα0, then That is, the maximum height offset g satisfies: g = f -1 (j). Wherein, the reference distance a between the center point of the burner head 31 and the wall surface on which the oil fume purification device is installed, the reference distance b between the infrared temperature sensor 20 and the wall surface on which the oil fume purification device is installed, the reference distance c between the infrared temperature sensor 20 and the tabletop of the stove 30, and the reference offset z of the infrared temperature sensor 20 along the first direction X relative to the center of the corresponding burner head 31 are all design parameters, which are constants. The radius k0 of the field of view detection area of the infrared temperature sensor 20 when the oil fume purification device is in the first installation state is a set value, which can also be understood as a known value. The maximum height offset g is a variable, that is, the diameter j of the burner head 31 region can be understood as a function of the maximum height offset g, j = f(g). When the value of the diameter j of the burner head 31 region is set, the value of the maximum height offset g can be inversely calculated through the inverse function g = f -1 (j). Subsequently, the oil fume purification device can be installed according to the value of the maximum height offset g, so as to ensure that the actual installation height of the oil fume purification device can meet the temperature detection accuracy requirements of the infrared temperature sensor 20.

[0077] Similarly, Figure 10b is Figure 8b the triangular similarity relationship between the field of view detection area of the infrared temperature sensor and the burner head region of the stove, as shown in Figure 1 , Figure 8b and Figure 10b , as shown in The same content will not be repeated.

[0078] The above content of the embodiment only discusses the corresponding relationship between the infrared temperature sensor 20 and the corresponding burner head 31, but does not explain the number of infrared temperature sensors 20. Alternatively, continuing to refer to Figure 1 , the stove 30 is provided with two burner heads 31, and the smoke collecting hood 10 is provided with two infrared temperature sensors 20, and the two infrared temperature sensors 20 correspond to the two burner heads 31 respectively; in the first direction X, the two infrared temperature sensors 20 are located on the two sides away from each other of the two burner heads 31 respectively; wherein, the first direction X is parallel to the direction of the center line of the two burner heads 31 on the stove 30.

[0079] Alternatively, continuing to refer to Figure 6The two burners 31 are provided on the cooktop 30, and the two infrared temperature sensors 20 are provided on the smoke hood 10 and correspond to the two burners 31 respectively; the two infrared temperature sensors 20 are arranged close to each other and in the middle of the two burners 31 in the first direction X; the first direction X is parallel to the direction of the center line of the two burners 31 on the cooktop 30.

[0080] Figure 11a and Figure 11b are two schematic diagrams of the position of the field of view detection area of the infrared temperature sensor and the burner area of the cooktop provided by the embodiments of the present application, as shown in Figure 11a and Figure 11b The maximum height offset g can be determined according to the distance between the center of the field of view detection area of the infrared temperature sensor 20 with the center point O and the center of the field of view detection area of the infrared temperature sensor 20 with the center point O1, and the field of view detection area of the infrared temperature sensor 20 with the center point O1 cannot be offset outside the burner 31 area of the cooktop 30. Figure 11a and Figure 11b As shown in Figure 6 , the relative installation of the oil fume purification equipment in upward and downward offset relative to the reference installation height is illustrated, and Figure 11a is taken as an example for illustration, it can be obviously seen that j / 2=k1+L, and similarly, Figure 11b is taken as an example for illustration, it can be obviously seen that j / 2=k1+L. For the same content, please refer to the above embodiments, which will not be repeated here.

[0081] Further, the maximum height offset g is determined based on the following parameters: the reference distance a between the center point of the burner 31 and the wall surface on which the oil fume purification equipment is installed; the reference distance b between the infrared temperature sensor 20 and the wall surface on which the oil fume purification equipment is installed; the reference distance c between the infrared temperature sensor 20 and the tabletop of the cooktop 30; the spacing e between the centers of the two burners 31; and the radius k0 of the field of view detection area of the infrared temperature sensor 20 when the oil fume purification equipment is in the first installation state; wherein the first installation state is that the oil fume purification equipment is installed on the installation wall surface according to the reference installation height.

[0082] Specifically, Figure 6 As shown in Figure 6 , the infrared temperature sensor 20 can be point A, the center point of the burner 31 can be point O, and point O is also the center point of the field of view detection area of the infrared temperature sensor 20 when the oil fume purification equipment is in the first installation state, and the center line length d0 of the infrared temperature sensor 20 and the corresponding burner 31 when the oil fume purification equipment is in the first installation state can be line segment AO, and the following can be obtained and then,

[0083] Optionally, Figure 12a yes Figure 11a The diagram shows the triangular similarity between the field of view detection area of ​​the infrared temperature sensor and the burner area of ​​the stove. Figure 6 , Figure 11a and Figure 12a As shown, the center point of the burner head 31 can be point O, which is also the center point of the field of view detection area of ​​the infrared temperature sensor 20 when the fume purification equipment is in the first installation state. The infrared temperature sensor 20 can be point A. The vertical projection point of the infrared temperature sensor 20 on the countertop of the stove 30 can be point B. The center point of the field of view detection area of ​​the infrared temperature sensor 20 when the fume purification equipment is in the second installation state can be point O1. The position point corresponding to the installation height of the infrared temperature sensor 20 when the fume purification equipment is in the second installation state can be point P. The reference distance a between the center point of the burner head 31 and the wall where the fume purification equipment is installed can be line segment OD. The reference distance b between the infrared temperature sensor 20 and the wall where the fume purification equipment is installed can be line segment CD. The reference distance c between the infrared temperature sensor 20 and the countertop of the stove 30 can be line segment AB. The distance e between the centers of the two burners 31 can be twice the line segment BC. The maximum height offset g can be line segment AP.

[0084] Furthermore, triangle OAB can be understood as a schematic diagram of the triangular relationship when the fume purification equipment is in its first installation state, and triangle O1PB can be understood as a schematic diagram of the triangular relationship when the fume purification equipment is in its second installation state. Figure 12a It is evident from the diagram that triangles OAB and O1PB are similar triangles. Therefore, line segment AB / line segment PB = line segment AO / line segment PO1. Here, line segment AB is c, line segment PB is c+g, and line segment AO is the length d0 of the line connecting the center of the infrared temperature sensor 20 and the corresponding burner head 31 when the fume purification equipment is in its first installation state. Line segment PO1 represents the length d1 of the line connecting the center of the infrared temperature sensor 20 and the corresponding burner head 31 when the fume purification equipment is in its second installation state. That is, Similarly, line segment AB / line segment PB = line segment OB / line segment O1B. Where line segment AB is c, line segment PB is c+g, line segment OB forms right triangles with line segments BC and OC respectively, and line segment BC is e / 2. Line segment OC = line segment CD - line segment OD = ba. Therefore, line segment OB is... Line segment O1B = line segment OB + line segment OO1, where line segment OO1 is the offset L of the center of the field of view detection area of ​​the infrared temperature sensor 20 when the fume purification equipment is in the second installation state, relative to the center of the field of view detection area of ​​the infrared temperature sensor 20 when the fume purification equipment is in the first installation state. That is,

[0085] Furthermore, j / 2 = k1 + L, k1 = d1 × tanα0, then That is, the maximum height offset g satisfies: g = f -1 (j). Among them, the reference distance a between the center point of the burner head 31 and the wall where the fume purification equipment is installed, the reference distance b between the infrared temperature sensor 20 and the wall where the fume purification equipment is installed, the reference distance c between the infrared temperature sensor 20 and the countertop of the stove 30, and the distance e between the centers of the two burners 31 are all design parameters and are constants. The radius k0 of the field of view detection area of ​​the infrared temperature sensor 20 when the fume purification equipment is in its first installation state is a set value, which can also be understood as a known value. The maximum height offset g is a variable; that is, the diameter j of the burner head 31 area can be understood as a function of the maximum height offset g, j = f(g). Once the value of the diameter j of the burner head 31 area is set, it can be determined using the inverse function g = f(g). -1 (j) Calculate the value of the maximum height offset g in reverse. Then, the oil fume purification equipment can be installed according to the value of the maximum height offset g to ensure that the actual installation height of the oil fume purification equipment can meet the temperature detection accuracy requirements of the infrared temperature sensor 20.

[0086] Similarly, Figure 12b yes Figure 11b The diagram shows the triangular similarity between the field of view detection area of ​​the infrared temperature sensor and the burner area of ​​the stove. Figure 6 , Figure 11b and Figure 12b As shown, it can also be obtained The same content will not be repeated.
