[0002] During the user's cooking process, the range hood can discharge a large amount of oil fumes generated during cooking, thereby improving the air quality in the kitchen, reducing the potential fire hazard, and ensuring the comfort and cleanliness of the kitchen environment. Since the most important function of the range hood is to smoke, it is very important to determine the smoking performance of the range hood.

[0003] Currently, the smoking effect of the range hood is mainly determined by a smoke generating device or various demonstration props. Specifically, first, a cooking scenario is created in the kitchen, such as frying or stir-frying, and the range hood is in a normal working state. Further, a smoke generator or a smoke generating device is used to generate thick smoke in the cooking area, and it is manually checked whether the range hood can effectively discharge the smoke in a timely manner.

[0004] However, the accuracy of manually determining the smoking performance of the range hood is relatively low. Summary of the Invention

DETAILED DESCRIPTION

This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present application.

[0065] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0066] Before introducing the embodiments of the present application, the application background of the embodiments of the present application is first explained:

[0067] In modern family kitchens, range hoods occupy an important position. Range hoods can exhaust a large amount of oil smoke generated during cooking, improve the air quality of the kitchen, protect the health of family members, reduce the deposition of oil smoke, and ensure the comfort and cleanliness of the kitchen environment. At the same time, range hoods can significantly reduce the accumulation of grease in the cooking area, reduce the hidden dangers of fire, and improve the safety of the kitchen.

[0068] The most important function of a range hood is to extract smoke. Currently, the smoke extraction effect of a range hood is mainly determined through smoke generating equipment or various demonstration props. Specifically, a cooking scene is first created in the kitchen, such as frying or cooking, so that the range hood is in normal working condition. Furthermore, a smoke indicator or smoke generating equipment is used to generate thick smoke in the cooking area, and a manual inspection is performed to check whether the range hood can exhaust the smoke in a timely and effective manner.

[0069] However, the existing technology mainly judges the smoke extraction effect of the range hood subjectively through manual observation. Since the rigor of the manual judgment process cannot be guaranteed, the accuracy of the determined smoke extraction effect is low. For consumers, since there is no quantitative data related to the smoke extraction effect, it is impossible to intuitively compare the smoke extraction effects of multiple range hoods horizontally to determine which model of range hood has a better smoke extraction effect. Therefore, it is very important to quantify the smoke extraction effect of the range hood.

[0070] Based on the above technical problems, the inventor discovered during research on the working process of the range hood that oil smoke is tiny suspended particles generated when food is heated and releases oil. The more these tiny suspended particles are, the higher the concentration of oil smoke is. Considering that a particle concentration tester can be used to detect particulate matter in the air, multiple particle concentration testers can be set on the range hood. In a cooking scenario, after the range hood has been working for a period of time, the smoking effect of the range hood can be determined based on the particle concentrations detected by multiple particle concentration testers. In this way, the smoking effect of the range hood can be quantified, and the determination process does not require subjective judgment by the staff, which effectively improves the accuracy of the determined smoking effect.

[0071] For example, the method for determining the smoke extraction performance of a range hood provided in the embodiment of the present application can be applied to Figure 1 and Figure 2 The scene diagram shown.

[0072] Figure 1 A schematic diagram of a scenario of a method for determining the smoke extraction performance of a range hood provided in an embodiment of the present application. Figure 1 As shown, the scene includes a European-style range hood 11, an electronic device 13, and a plurality of particle concentration testers, namely a particle concentration tester 121, a particle concentration tester 122, a particle concentration tester 123, a particle concentration tester 124, and a particle concentration tester 125.

[0073] In practical applications, each particle concentration tester is set at a different location to obtain the particle concentration at the different location.

[0074] Reference Figure 1 , particle concentration tester 121, particle concentration tester 122, particle concentration tester 124, and particle concentration tester 125 are set in the cooking area, and particle concentration tester 123 is set in the breathing area. Specifically, particle concentration tester 121 is set 20 mm upward from the bottom end of the left side of the smoke collecting chamber of the European-style range hood 11, and is on the same vertical line as the leftmost position point (point m) of the left stove. Particle concentration tester 122 is set 20 mm upward from the bottom end in front of the smoke collecting chamber of the European-style range hood 11, and is on the same vertical line as the frontmost position point (point n) of the left stove. Particle concentration tester 123 is set in the breathing zone at a height of 13,300 mm from the ground and 700 mm behind the smoke collecting chamber of the European-style range hood 11. The particle concentration tester 124 is set 20 mm upward from the bottom of the front of the smoke collecting chamber of the European-style range hood 11, and is on the same vertical line as the position point (point p) on the front side of the right stove. The particle concentration tester 125 is set 20 mm upward from the bottom of the right side of the smoke collecting chamber of the European-style range hood 11, and is on the same vertical line as the position point (point q) on the right side of the right stove.

[0075] In the process of determining the smoke extraction performance of the European-style range hood 11, each particle concentration tester can collect the particle concentration in real time and send the collected particle concentration to the electronic device 13. The electronic device 13 receives the particle concentration sent by each particle concentration tester and further processes it to determine the smoke extraction performance of the range hood.

[0076] It should be understood that the specific manner and principle of the electronic device 13 determining the smoke extraction performance of the range hood will be described in detail in the following embodiments and will not be elaborated herein.

[0077] Next, the locations where the particle concentration testers are set in the scenario where the range hood is a side-suction range hood are explained.

[0078] Figure 2 A schematic diagram of another method for determining the smoke extraction performance of a range hood provided in an embodiment of the present application. Figure 2 As shown, the scene includes: a side-suction range hood 14 and multiple particle concentration testers, namely particle concentration tester 151, particle concentration tester 152, particle concentration tester 153, particle concentration tester 154, and particle concentration tester 155.

[0079] Particle concentration tester 151, particle concentration tester 152, particle concentration tester 154, and particle concentration tester 155 are set in the cooking area, and particle concentration tester 153 is set in the breathing area. Specifically, particle concentration tester 151 is set 20 mm upward from the bottom end of the left side of the smoke collecting chamber of the side-suction range hood 14, and is on the same vertical line as the leftmost position point (point h) of the left stove. Particle concentration tester 152 is set 20 mm upward from the bottom end of the plate in front of the smoke collecting chamber of the side-suction range hood 14, and is on the same vertical line as the frontmost position point (point i) of the left stove. Particle concentration tester 153 is set in the breathing zone at a height b of 15300 mm from the ground, and 700 mm from the left side of the smoke collecting chamber of the side-suction range hood 14. The particle concentration tester 154 is set 20 mm upward from the bottom of the smoke collecting chamber in front of the side-suction range hood 14, and is on the same vertical line as the frontmost position point (point j) of the right stove. The particle concentration tester 155 is set 20 mm upward from the bottom of the right side of the smoke collecting chamber of the side-suction range hood 14, and is on the same vertical line as the rightmost position point (point k) of the right stove.

[0080] It should be understood that Figure 1 and Figure 2 There may be other possibilities for the installation location of each particle concentration tester, and each scene may also include other equipment. The number of particle concentration testers in each scene may also be determined based on actual conditions, and the embodiments of the present application do not impose specific restrictions on this.

[0081] The technical solution of the present application is described in detail below through specific embodiments.

[0082] It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0083] Figure 3This is a flow chart of a method for determining the smoke extraction performance of a range hood according to an embodiment of the present application. Figure 3 As shown, the method for determining the smoke extraction performance of the range hood may include the following steps:

[0084] S31. When it is detected that the range hood and the first burner of the stove start to work at the same time and the working time reaches any one of a plurality of target cooking time periods, a first particle concentration of each area is obtained.

[0085] The execution subject of the embodiment of the present application is an electronic device, which can be a terminal device, such as a mobile phone, a laptop computer, a desktop computer, etc., or a server, or a range hood. In actual applications, whether the electronic device is a terminal device, an electronic device, or a range hood can be determined according to actual conditions, and the embodiment of the present application does not specifically limit this.

[0086] In this step, a stove can be used for cooking to produce oil smoke, and a range hood can be used for exhausting smoke, so that the exhaust performance of the range hood can be determined during the exhaust process. The electronic device can communicate with the range hood and the stove, and when it is detected that the range hood and the first burner of the stove start working at the same time, the particle concentration of the two after a certain working time is obtained.

[0087] Among them, the area is the cooking area or the breathing area.

[0088] It should be understood that the breathing zone is the area where the user breathes during the cooking process; the cooking zone refers to the area where fumes and odors are generated during cooking.

[0089] Optionally, a particle concentration tester can be pre-installed in the breathing zone and the cooking zone respectively, and the particle concentration tester can obtain the particle concentration within its collection range. Optionally, the setting position of the particle concentration tester can refer to Figure 1 and Figure 2 The contents shown are not repeated here.

[0090] In a possible implementation, since the cooking area is larger and the breathing area is smaller, multiple particle concentration testers can be set in the cooking area, and one particle concentration tester can be set in the breathing area. When it is detected that the range hood and the first burner of the stove start working at the same time, the timing starts, and the working time obtained by timing is obtained. Afterwards, when the working time reaches any target cooking time among multiple target cooking times, the third particle concentration sent by each particle concentration tester is obtained. Then, for each target cooking time, according to the third particle concentration corresponding to the target cooking time, and the area corresponding to each third particle concentration, the first particle concentration of each area at the target cooking time is determined. Finally, the timing is stopped.

[0091] It should be understood that the electronic device can obtain the third particle matter concentration collected by each particle matter concentration tester in real time, and can also obtain the third particle matter concentration collected by each particle matter concentration tester when the working time reaches any target cooking time. The embodiment of the present application does not specifically limit the manner in which the electronic device obtains the third particle matter concentration collected by each particle matter concentration tester.

[0092] Exemplarily, the target cooking time may be 1 minute, 2 minutes, 3 minutes, etc. It should be understood that the target cooking time may also be other values, which may be determined according to actual conditions, and the present application embodiment does not impose any specific limitation on this.

[0093] It should be understood that the first burner head may be a burner head preset in the cooker. For example, for a cooker having two burners, the first burner head may be a left burner head and / or a right burner head.

[0094] S32. For each area, determine a second particle concentration for characterizing the oil smoke concentration in the area according to the first particle concentration in the area at each target cooking time.

[0095] In this step, for each area, after determining the first particle matter concentration of the area at each target cooking time, the first particle matter concentration of each target cooking time can be comprehensively considered and processed to determine the second particle matter concentration used to characterize the regional oil fume concentration.

[0096] In a possible implementation, for each area, the second particle concentration of the area is determined by subtracting the second initial particle concentration of the area from the average value of the first particle concentration of the area at each target cooking time.

[0097] In a possible implementation, for each area, the second particle concentration of the area is determined by subtracting the weighted average of the first particle concentration of the area at each target cooking time from the second initial particle concentration of the area.

[0098] In a possible implementation, for each area, the difference between the minimum value of the first particle concentration of the area at each target cooking time and the second initial particle concentration of the area is determined as the second particle concentration of the area.

[0099] In a possible implementation, for each area, the second particle concentration of the area is determined by subtracting the second initial particle concentration of the area from the maximum value of the first particle concentration of the area at each target cooking time.

[0100] It should be understood that the second initial particle concentration of each region in the above implementation manners refers to the particle concentration of the region before cooking, that is, the particle concentration in the environment of the region before cooking.

[0101] Since the particle concentration collected by the particle concentration tester during the cooking process is the sum of the particle concentration in the environment and the particle concentration in the oil fume, when calculating the second particle concentration of each region, on the basis of processing the first particle concentration of the region at each target cooking duration, the second initial particle concentration is subtracted, so as to ensure that the calculated second particle concentration is more accurate.

[0102] S33. Determine the target smoking performance of the range hood according to the second particle concentration of each region.

[0103] In this step, since the greater the particle concentration, the greater the oil fume, and the worse the smoking performance of the range hood. Therefore, the target smoking performance of the range hood can be determined according to the second particle concentration in the cooking area and the breathing area.

[0104] In a possible implementation manner, determine the target smoking performance of the range hood according to the second particle concentration of each region and the smoking performance grade table.

[0105] Among them, the smoking performance grade table is used to represent the mapping relationship among the smoking performance grade, the particle concentration range in the cooking area, and the particle concentration range in the breathing area, and the target smoking performance is used to represent the smoking performance grade of the range hood.

[0106] Exemplarily, the smoking performance grade table can be represented by Table 1

[0107] Table 1

[0108] As shown in Table 1, the smaller the smoking performance grade, the better the smoking performance of the range hood, that is, the smoking performance grade 1 represents the best smoking performance of the range hood, and the smoking performance grade 5 represents the worst smoking performance of the range hood.

[0109] It should be understood that the mapping relationship among the smoking performance grade, the particle concentration range in the cooking area, and the particle concentration range in the breathing area represented by the smoking performance grade table can be determined according to the test data. That is to say, the values in the smoking performance grade table shown in Table 1 can also be replaced with other values according to the test results. The embodiments of the present application do not specifically limit this.

[0110] The embodiment of the present application provides a method for determining the smoking performance of a range hood. When it is detected that the range hood and the first burner of the stove start working at the same time, and the working time reaches any one of multiple target cooking times, the first particle concentration of each area is obtained, and for each area, the second particle concentration used to characterize the oil fume concentration of the area is determined according to the first particle concentration of the area at each target cooking time, and the target smoking performance of the range hood is determined according to the second particle concentration of each area. Among them, the area is a cooking area or a breathing area. In this technical solution, in the scenario of using a range hood and a stove for cooking, the particle concentration of each area is determined, so that the smoking performance of the range hood is quantified according to the particle concentration of each area. Since the entire processing process does not require human participation, it only needs to be calculated based on the data collected by the particle concentration tester, which effectively increases the accuracy of the determined smoking performance.

[0111] Before determining the smoke extraction performance of the range hood, it is necessary to determine whether the current environment is suitable for performing the smoke extraction performance determination process. Next, a method for determining whether the current environment is suitable for determining the smoke extraction performance of the range hood will be described in detail through a specific embodiment.

[0112] Figure 4 This is a flow chart of Embodiment 2 of the method for determining the smoke extraction performance of a range hood provided in the present application. Figure 4 As shown, before detecting that the cooker starts to work, the method for determining the smoke extraction performance of the range hood may further include the following steps:

[0113] S41. Obtain a first initial particle concentration sent by each particle concentration tester.

[0114] S421: If each first initial particle matter concentration is less than a preset concentration, determine a second initial particle matter concentration in each area according to each first initial particle matter concentration and the area corresponding to each first initial particle matter concentration.

[0115] In this step, when each first initial particle concentration is less than the preset concentration, it means that the particle concentration in the current environment is small, which will not affect the subsequent process of determining the smoke extraction performance of the range hood according to the particle concentration. Based on this, the second initial particle concentration of each area can be further determined, so that the particle concentration of each area during the cooking process can be corrected according to the second initial particle concentration.

[0116] The second initial particle concentration is used to represent the particle concentration in the area when no cooking is done.

[0117] For example, the preset concentration may be 80 ug / m 3 、85ug / m 3、90ug / m 3 wait.

[0118] S431, controlling the range hood and the first stove of the stove to start working;

[0119] S422: If any first initial particle concentration is greater than or equal to a preset concentration, control the range hood to start the stirring fan and start the range hood at the highest speed.

[0120] In this step, if any first initial particle concentration is greater than or equal to the preset concentration, it means that the particle concentration in the current environment is high, which greatly interferes with the subsequent process of determining the smoking performance. Therefore, ventilation is required to reduce the particle concentration in the current environment.

[0121] In the above embodiment, it is determined whether the current environment is suitable for determining the smoke extraction performance of the range hood, so that the operation is performed when it is suitable. Figure 3 The process of determining the smoke extraction performance of the range hood in the illustrated embodiment improves the accuracy of subsequent determination of the smoke extraction performance.

[0122] Optionally, in some embodiments, when the stove has multiple stoves, cooking can be performed on different stoves to determine the particle concentration of each area under different cooking environments, and the target particle concentration for characterizing the oil smoke concentration of each area is determined by combining multiple cooking environments. In this way, the particle concentration of each area is comprehensively determined by considering multiple cooking environments, which effectively improves the accuracy of the determination.

[0123] In one possible implementation, after determining, for each area, a second particle concentration used to characterize the regional oil fume concentration based on the first particle concentration of the area at each target cooking time, if the first burner of the stove stops working and the second target burner of the stove and the range hood start working at the same time, then for each area, a fourth particle concentration used to characterize the regional oil fume concentration is determined; for each area, the average of the third particle concentration and the fourth particle concentration of the area is determined as the target particle concentration of the area.

[0124] Accordingly, in this implementation, the target smoke extraction performance of the range hood is determined according to the second particle concentration in each area, which can be achieved in the following manner:

[0125] Determine the target exhaust performance of the range hood based on the target particle concentration in each area.

[0126] The method for determining the smoke extraction performance of a range hood based on any of the above embodiments is explained below by using a specific example.

[0127] Exemplarily, the method for improving the smoke extraction performance of a range hood comprises the following steps:

[0128] Step 1: Install each particle concentration tester to the set position.

[0129] It should be understood that the specific location point can refer to Figure 1 and Figure 2 The relevant content will not be repeated here.

[0130] Step 2: Open the laboratory door and window of the simulated kitchen for ventilation, turn on the stirring fan of the range hood, and control the range hood to run at the highest speed for at least 30 minutes.

[0131] Step 3: Determine the particle concentration collected by each particle concentration tester. If all are less than 80ug / m 3 , then calculate the average value of the particle concentration collected by the particle concentration tester in each area (the average value of the particle concentration collected by the particle concentration tester in the cooking area is C10, and the average value of the particle concentration collected by the particle concentration tester in the breathing area is C20); if the particle concentration collected by any particle concentration tester is greater than or equal to 80ug / m 3 , go to step 2.

[0132] Step 4: Select 20g of butter, turn on the left stove of the electric stove, add butter to the pot of the left stove, obtain the particle concentration collected by each particle concentration tester at 1min, 2min, and 3min after adding the butter, and determine the average particle concentration of the particle concentration collected by the particle concentration tester in each area at 1min, 2min, and 3min (at 1min, the average particle concentration in the cooking area is C 11 The average particle concentration in the breathing zone is C 21 ; At 2 minutes, the average particle concentration in the cooking area is C 12 The average particle concentration in the breathing zone is C 22 ; At 3 minutes, the average particle concentration in the cooking area is C 13 The average particle concentration in the breathing zone is C 23 ). Then, the particle concentration used to characterize the oil smoke concentration in each area is calculated according to the following formula:

[0133]

[0134]

[0135] In the above formula, a n is the particle concentration in the cooking area, b n is the particle concentration in the breathing zone.

[0136] It should be understood that steps 2 to 4 are for determining the particle concentration in each area by taking the left stove of the electric stove as the test point.

[0137] Referring to the above steps 2 to 4, the particle concentrations of each area are determined again by taking the right stove of the electric stove as the test point. It should be understood that the method of determining the particle concentrations of each area by taking the right stove of the electric stove as the test point is the same as the method of determining the particle concentrations of each area by taking the right stove of the electric stove as the test point. The only difference is that the left stove of the electric stove is turned on and 20g of butter is added to the pot of the left stove.

[0138] Step 5: Based on the particle concentration of each area determined by taking the left stove of the electric stove as the test point and the particle concentration of each area determined by taking the right stove of the electric stove as the test point, the target particle concentration of each area is determined based on the combination of the two. The target particle concentration of each area can be determined by the following formula:

[0139]

[0140]

[0141] In the above formula, a is the target particle concentration in the cooking zone, and b is the target particle concentration in the breathing zone.

[0142] Step six, determine the smoke extraction performance level of the range hood according to the target particle concentration of each area and the smoke extraction performance level table.

[0143] It should be understood that during the operation of the electric furnace, the power of the electric furnace is always maintained at 2000W.

[0144] The embodiments of the present application quantify the oil suction performance of the range hood, thereby improving the accuracy of determining the oil suction performance, making it convenient for consumers to make horizontal comparisons of multiple range hoods based on the quantified oil suction performance levels, helping to encourage range hood merchants to improve the oil suction performance of their range hoods, and promoting the development of healthy competition in the industry.
