[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] Kitchens are usually equipped with range hoods, such as top suction, side suction, low suction (integrated stove type), Chinese type, tower type, top side double suction, bottom side double suction and other types of range hoods, so as to suck the oil fume gas in the kitchen into the body and discharge it outdoors. With the further improvement of the performance of range hoods, range hoods are usually also equipped with sensors to detect the environmental state of the range hood. However, the environment in which the range hood is located is usually accompanied by oil, oil smoke and water vapor. As a result, the sensor may be contaminated by oil during use, thereby affecting the detection accuracy of the sensor. After oil smoke and water vapor enter the sensor, it may cause the sensor to be damaged and malfunction, thereby reducing the service life of the sensor. At the same time, it will also affect the detection effect of the sensor, resulting in low detection reliability of the sensor.

[0036] To this end, the embodiments of the present application provide a smoke hood assembly and a range hood. The shell assembly in the smoke hood assembly can protect the detection assembly to prevent oil stains, oil smoke, water vapor, etc. from contacting the detection assembly and causing damage to the detection assembly. At the same time, the shell assembly is partially embedded and fixed in the installation cavity, which improves the connection firmness between the shell assembly and the smoke hood, thereby improving the connection firmness between the detection assembly and the smoke hood, and further ensuring the detection reliability of the detection device.

[0037] The fume hood assembly and the range hood provided in the present application are exemplarily introduced below with reference to the accompanying drawings.

[0038] The embodiment of the present application provides a range hood, the range hood includes a fume hood assembly and a fan assembly, the fume hood assembly is provided with a fume chamber, the fan assembly is located above the fume hood assembly, and the fan assembly is provided with an air outlet chamber connected to the fume chamber, when the range hood is working, the range hood will suck the fume gas in the target environment (such as the kitchen) into the fume chamber in the fume hood assembly, and then discharge the fume gas in the fume chamber to the outside through the air outlet chamber. Here, it is worth understanding that the fan assembly can be provided with a fan and a pneumatic device, the fan and the pneumatic device are both located in the air outlet chamber, when the range hood is working, the pneumatic device will drive the fan to rotate to discharge the fume gas in the air outlet chamber to the outside, and the fan assembly can also be provided with other structures, and this application does not make specific restrictions on this.

[0039] In order to detect the kitchen fume environment status in real time and accurately control the working status of the fume hood assembly to better maintain the kitchen environment, in one example, Figure 1 As shown, the smoke hood assembly may include a smoke hood 1 and a detection device 2. The smoke hood 1 is provided with an installation cavity 1A. A portion of the detection device 2 is located in the installation cavity 1A and is fixedly connected to the smoke hood 1, and another portion of the detection device 2 is located outside the installation cavity 1A. The detection device 2 can collect the temperature and / or concentration of the target environment (e.g., the kitchen) and adjust the working state of the range hood accordingly.

[0040] Here, it is worth mentioning that the temperature collected by the detection device 2 can be the temperature of the pots and pans in the kitchen, the temperature of the stove and the temperature above the stove, that is, the detection device 2 can collect and detect the temperature of all places between the top of the stove and the range hood, and the concentration collected by the detection device 2 can be the oil fume concentration and odor concentration in the kitchen, and it can also be other temperatures or concentrations under the oil fume environment state. This application does not make any specific restrictions on this.

[0041] In order to enable the detection device 2 to collect the temperature and / or concentration of the kitchen and adjust the working state of the range hood accordingly, in one example, please refer to Figures 2 to 3, the detection device 2 may include a shell component 21 and a detection component 22, a part of the shell component 21 is located in the installation cavity 1A and is fixedly connected to the smoke hood 1, and the other part of the shell component 21 is located outside the installation cavity 1A, and the detection component 22 is arranged in the shell component 21, and the detection component 22 is used to collect temperature and / or concentration and adjust the working state of the range hood accordingly to better maintain the kitchen environment. In this example, the detection component 22 is arranged in the shell component 21, that is, the shell component 21 can protect the detection component 22 to avoid contact between oil, oil smoke, water vapor, etc. and the detection component 22, resulting in damage to the detection component 22, and then affecting the detection effect of the detection component 22, that is, by arranging the detection component 22 in the shell component 21 and fixing it on the smoke hood 1, the detection reliability of the detection component 22 is improved, and the service life of the detection component 22 is also improved, so that the detection component 22 can accurately control the working state of the smoke hood component based on the detected kitchen oil fume environment state, so as to better maintain the kitchen environment. At the same time, the shell component 21 is partially embedded and fixed in the installation cavity 1A, which avoids the problem of the shell component 21 falling off due to external force, improves the connection firmness between the shell component 21 and the smoke hood 1, thereby improving the connection firmness between the detection component 22 and the smoke hood 1, and further ensuring the detection reliability of the detection device 2.

[0042] In order to enable the housing assembly 21 to be partially embedded and fixed in the installation cavity 1A, in one example, please refer to Figures 4 to 5 The shell assembly 21 may include a fixed bracket 211 and a fixed shell 212. The fixed bracket 211 is located in the installation cavity 1A and is fixedly connected to the smoke hood 1. The fixed shell 212 is fixedly connected to the fixed bracket 211 and protrudes from the installation cavity 1A. The side of the fixed shell 212 is snap-fitted to the smoke hood 1. The detection assembly 22 is disposed in the fixed shell 212.

[0043] In this example, the shell component 21 can be embedded and fixed in the installation cavity 1A through the fixed bracket 211 to ensure the firmness of the connection between the shell component 21 and the smoke hood 1. At the same time, the fixed shell 212 is fixedly connected to the fixed bracket 211 and protrudes from the installation cavity 1A, so that the detection device 2 installed in the fixed bracket 211 can collect the temperature and / or concentration of the kitchen to ensure the collection and detection reliability of the detection device 2. Secondly, the side of the fixed shell 212 protruding from the installation cavity 1A is snapped with the smoke hood 1, that is, there is no gap between the side of the fixed shell 212 and the smoke hood 1, so as to avoid oil, oil smoke, water vapor, etc. entering the shell component 21 through the installation cavity 1A, causing the detection component 22 in the shell component 21 to be damaged and malfunction, thereby affecting the detection effect of the detection component 22, so as to improve the collection and detection reliability of the detection component 22, and at the same time improve the service life of the detection component 22. At the same time, it also avoids the problem that after the range hood is used for a long time, oil stains, oil smoke, water vapor, etc. are gathered in the smoke collecting hood 1 through the installation cavity 1A, causing the smoke collecting hood 1 to be seriously polluted and inconvenient to clean.

[0044] In order to enable the fixing bracket 211 to be embedded and fixed in the installation cavity 1A, in one example, please refer to Figures 6 to 9 The fixed bracket 211 may include a first bracket 2111 and a second bracket 2112. The first bracket 2111 is at least arranged around one side of the fixed shell 212 to achieve a fixed connection with the fixed shell 212. The second bracket 2112 is fixedly connected to the first bracket 2111, and a threaded hole 2112A is provided on the second bracket 2112. The second bracket 2112 can be fixed in the installation cavity 1A through the threaded hole 2112A by fasteners such as bolts and screws. In this way, the fixed bracket 211 can achieve a fixed connection with the smoke hood 1 through the second bracket 2112, and at the same time achieve a fixed connection with the fixed shell 212 through the first bracket 2111, so as to ensure the firmness of the connection between the smoke hood 1, the fixed bracket 211 and the fixed shell 212. At the same time, fasteners such as bolts and screws are hidden in the smoke hood 1, avoiding the problem of fasteners being exposed and affecting the aesthetics.

[0045] Optionally, in order to improve the connection firmness between the fixed bracket 211 and the fixed shell 212, the first bracket 2111 can be arranged around the fixed shell 212. In order to save manufacturing costs, the first bracket 2111 can be arranged only on one side of the fixed shell 212. This application does not make any specific restrictions on this.

[0046] In an example, see Figures 6 to 9In order to further improve the firmness of the fixed bracket 211 fixed on the smoke hood 1, the fixed bracket 211 can also include a positioning plate 2113, one side of the positioning plate 2113 is fixedly connected to the second bracket 2112 on at least one side, and the other side of the positioning plate 2113 is fixedly connected to the smoke hood 1. In this example, the fixed bracket 211 can be fixedly connected to the smoke hood 1 via the second bracket 2112 and the positioning plate 2113, and has high firmness and is convenient for disassembly and assembly.

[0047] In this example, since the fixed housing 212 is a three-dimensional structure rather than a planar structure, in one example, please refer to Figures 7 to 9 The fixed bracket 211 generally further includes a bending portion 2114, one end of which is fixedly connected to the first bracket 2111, and the other end of which is fixedly connected to the second bracket 2112. Thus, the first bracket 2111 and the second bracket 2112 located in different planes can be fixedly connected through the bending portion 2114, and the bending angle and size of the bending portion 2114 can be set based on the size of the fixed housing 212. Optionally, the first bracket 2111, the bending portion 2114 and the second bracket 2112 can be an integral structure formed by casting, or can be an independent structure, which can be set according to actual needs, and the present application does not make any specific restrictions on this.

[0048] Optionally, the fixing bracket 211 can be made of plastic material, for example, acrylonitrile-butadiene-styrene (ABS), polycarbonate (PC), polypropylene (PP) and thermoplastic polyurethanes (TPU). Plastic material is light, tough and low in cost.

[0049] In order to enable the detection assembly 22 to be fixed in the fixed housing 212, in one example, Fig.10 As shown, a receiving groove 212A is provided in the fixed shell 212, and the receiving groove 212A is used to receive the detection component 22, and the shape and size of the receiving groove 212A can be designed according to the shape and size of the detection component 22. For example, assuming that the detection component 22 is cylindrical as a whole, the interior of the receiving groove 212A is designed as a cylindrical cavity as a whole, so that the detection component 22 can be snapped and fixed in the fixed shell 212. The size of the receiving groove 212A can be set to be the same as the size of the detection component 22 to improve the fixing firmness. The size of the receiving groove 212A can be set to be larger than the size of the detection component 22 to facilitate disassembly and assembly. This application does not make specific restrictions on this.

[0050] After being used for a period of time, the detection component 22 needs to be inspected and replaced. In order to facilitate disassembly and assembly, the opening of the receiving groove 212A can be facing the installation cavity 1A. During installation, the detection component 22 can be installed into the receiving groove 212A through the opening. During disassembly, the detection component 22 can be removed from the receiving groove 212A through the opening, which makes disassembly and assembly easy.

[0051] In order to further improve the firmness of the detection assembly 22 fixed in the fixed housing 212, please refer to Figure 10 to Figure 11 An elastic member 212C may be further provided on the groove wall of the accommodating groove 212A, and a groove 22A may be provided on the shell of the detection component 22. The elastic member 212C is correspondingly engaged with the groove 22A to realize the connection between the detection component 22 and the fixed shell 212. The connection is highly firm and convenient for disassembly and assembly. At the same time, the elastic member 212C is correspondingly engaged with the groove 22A, which can also play a limiting role for the detection component 22, so that the detection component 22 can be limited to a preset position in the fixed shell 212. The preset position here can refer to the optimal position for the detection component 22 to achieve collection and detection, so as to ensure the collection and detection reliability of the detection component 22.

[0052] Optionally, the elastic member 212C may be a buckle with an elastic portion, or a protrusion provided with a spring, or other structures, and the present application does not impose any specific limitation on this.

[0053] In order to save manufacturing costs, only one elastic member 212C may be set on the groove wall of the accommodating groove 212A. In order to improve the firmness of the detection component 22 fixed in the fixed shell 212, multiple elastic members 212C may be arranged at intervals on the groove wall of the accommodating groove 212A. At the same time, multiple grooves 22A are also correspondingly arranged on the shell of the detection component 22. The multiple elastic members 212C are snap-connected with the multiple grooves 22A one by one to improve the firmness of the detection component 22 fixed in the fixed shell 212.

[0054] Optionally, when the height of the groove wall of the accommodating groove 212A is the same as the height of the detection component 22, an elastic member 212C can be set on the groove wall of the accommodating groove 212A. When the height of the groove wall of the accommodating groove 212A is lower than the height of the detection component 22, part of the groove wall of the accommodating groove 212A can be extended to form the elastic member 212C. The present application does not make any specific restrictions on this.

[0055] Optionally, a plurality of limiting ribs may be provided on the groove wall of the accommodating groove 212A, and the plurality of limiting ribs may limit and fix the detection component 22, so as to further improve the firmness of the detection component 22 fixed in the fixed shell 212. The accommodating groove 212A may also be provided with other limiting or fixing structures based on the structure of the detection component 22, and the present application does not impose any specific restrictions on this.

[0056] In order to enable the detection component 22 to be fixed in the receiving tank 212A while being able to collect and detect the temperature and / or concentration of the kitchen, in one example, please refer to Fig.10 and Fig.12 At least one through hole 212B for the detection component 22 to be exposed is formed on the bottom wall of the accommodating groove 212A away from the smoke collecting hood 1. The detection component 22 can collect and detect the temperature and / or concentration of the kitchen through the through hole 212B.

[0057] Optionally, the fixed shell 212 can be made of plastic material, such as acrylonitrile-butadiene-styrene copolymer, polycarbonate, polypropylene and thermoplastic polyurethane. Plastic material is light, tough and low in cost. The fixed shell 212 can also be made of other materials such as metal. This application does not make any specific restrictions on this.

[0058] Optionally, the fixed bracket 2111 and the fixed shell 212 can be an integral structure formed by casting, or can be an independent structure, and can be specifically configured according to actual needs, and this application does not make any specific restrictions on this.

[0059] In order to enable the detection component 22 to collect and detect the temperature and / or concentration of the kitchen and adjust the working state of the range hood accordingly, in one example, please refer to Figure 11 to Figure 12 The detection component 22 includes a sensor 221 and a controller 222. The sensor 221 is located in the receiving groove 212A and protrudes from the through hole 212B. The sensor 221 is used to collect temperature and / or concentration. The controller 222 is fixed in the receiving groove 212A and is electrically connected to the sensor 221. The controller 222 is used to receive the temperature and / or concentration collected by the sensor 221 and adjust the working state of the range hood accordingly.

[0060] In this example, the sensor 221 can collect and detect the temperature and / or concentration of the kitchen in real time to accurately know the oil fume condition of the kitchen and accurately judge the oil fume environment state of the kitchen, and send the collected temperature and / or concentration information to the controller 222, so that the controller 222 can control the range hood to switch to the corresponding working state based on this information, so as to improve the working reliability of the range hood and better maintain the kitchen environment.

[0061] For example, when the sensor 221 detects that the temperature of the kitchen is higher than the preset temperature, the preset temperature at this time may refer to the temperature at which the kitchen appliances (such as the stove) in the kitchen start to work. When the sensor 221 detects that the temperature of the kitchen is higher than the preset temperature, it means that the kitchen appliances have been working for a period of time. At this time, the range hood needs to work to maintain the kitchen environment, and the controller 222 will switch the range hood to the working mode to maintain the kitchen environment. When the sensor 221 detects that the temperature of the kitchen is lower than the preset temperature, it means that the kitchen appliances have been turned off and cooled. At this time, in order to save energy, the range hood does not need to work, and the controller 222 will switch the range hood to the off mode. Here, it is worth noting that the preset temperature can be set high or low according to actual needs, and this application does not make specific restrictions on this.

[0062] For another example, a range hood usually includes three levels of smoke intensities: low, medium, and high. When the sensor 221 detects that the kitchen fume concentration is higher than the maximum preset concentration, the kitchen environment is poor and the fume needs to be discharged in time. The controller 222 can switch the range hood to a high level to quickly absorb and discharge the fume to maintain the kitchen environment. After the range hood uses the high level for a period of time, the sensor 221 will detect that the kitchen fume concentration is lower than the maximum preset concentration and higher than the minimum preset concentration. The kitchen environment is relieved. At this time, the controller 222 can switch the range hood to a low level to save energy and avoid unnecessary losses.

[0063] Here, it is worth noting that the sensor 221 can only collect temperature and / or concentration, and then send the collected temperature and / or concentration information to the controller 222. The controller 222 can be provided with a processing program to process the received information to obtain the working state to be switched, and switch the working state of the range hood accordingly. The sensor 221 can also have a processing function, that is, after the sensor 221 collects information such as temperature and / or concentration, it will detect and process the information to obtain the working state to be switched, and send an electrical signal indicating the working state to be switched to the controller 222, so that the controller 222 can directly control the switching of the working state of the range hood based on the electrical signal. This application does not make any specific restrictions on this.

[0064] The specific location and quantity of the sensor 221 can be set according to actual needs. For example, in order to save production costs, only one sensor 221 can be set, and the sensor 221 is located in the receiving groove 212A and protrudes from the through hole 212B to collect temperature and concentration. In order to improve the accuracy of the detection component 22 in collecting and detecting temperature and concentration, the number of sensors 221 is at least one, and the sensor 221 is located in the receiving groove 212A and protrudes from the through hole 212B. Different sensors 221 are used to collect different information and do not interfere with each other to improve detection accuracy.

[0065] In one example, when there are multiple sensors 221, the bottom wall of the receiving groove 212A may include at least two mounting planes, and multiple sensors 221 are distributed on at least two mounting planes to collect and detect temperature and concentration at different angles. For example, Fig.13 As shown, the number of sensors 221 can be set to three, namely a first sensor 221a for detecting temperature, a second sensor 221b for detecting oil fume concentration, and a third sensor 221c for detecting odor concentration. The bottom wall of the accommodating groove 212A corresponds to two installation planes. At this time, three through holes 212B are correspondingly arranged on the two installation planes, and the sizes and shapes of the three through holes 212B correspond to the first sensor 221a, the second sensor 221b, and the third sensor 221c respectively. One of the installation planes faces the stove, and the first sensor 221a and the second sensor 221b can be adjacently distributed on the installation plane facing the stove to improve the detection accuracy of temperature and oil fume concentration. The third sensor 221c can be located on another installation plane.

[0066] Furthermore, since there are usually two stoves in the kitchen, in order to enable the sensor 221 to collect the concentration and temperature of the two stoves at the same time, the sensor 221 can be set in the middle of the smoke hood 1, that is, in the middle of the two stoves and facing the plane where the stoves are located. Exemplarily, when the smoke hood 1 provided by the present application adopts a wall-mounted structure, for example, Figure 1 As shown, the smoke hood 1 may include a first hood body 11 and a second hood body 12 set at an angle, wherein the first hood body 11 is fixed to the wall of the kitchen, and the second hood body 12 is provided with a fume chamber. At this time, the sensor 221 may be set at a lower position in the middle of the second hood body 12 to collect and detect the temperature and concentration of the two stoves. The sensor 221 may also be set at the side position of the smoke hood 1, and the present application does not make any specific restrictions on this.

[0067] Here, it is worth mentioning that when the bottom wall of the accommodating groove 212A includes multiple installation planes, that is, when the bottom wall of the accommodating groove 212A is an irregular structure, the first bracket 2111 arranged around the fixed shell 212 is equivalent to being arranged around the bottom wall of the accommodating groove 212A, that is, the first bracket 2111 can also be an irregular structure.

[0068] In one example, if Fig.14 As shown, the controller 222 may include a mounting base 2221, the mounting base 2221 is fixed in the receiving groove 212A, the controller body 2222 is fixed on the mounting base 2221 and is electrically connected to the sensor 221, and is used to receive the temperature and / or concentration collected by the sensor 221, and adjust the working state of the range hood accordingly. In this example, the controller body 2222 may be fixed in the fixed housing 212 through the mounting base 2221, and the controller body 2222 may be provided with control circuits, processing chips and other structures to achieve the reception of the temperature and / or concentration collected by the sensor 221, and to adjust the working state of the range hood accordingly.

[0069] In order to ensure the firmness of the controller body 2222 being fixed on the mounting seat 2221, in one example, one of the controller body 2222 and the mounting seat 2221 is provided with a buckle, and the other of the two is provided with a groove, and the buckle is engaged with the groove to achieve a firm connection between the controller body 2222 and the mounting seat 2221. For example, Fig.14 As shown, a buckle portion 2222A is provided on the controller body 2222, and a groove is provided at a corresponding position on the mounting seat 2221, and the buckle portion 2222A is engaged with the groove to achieve a fixed connection between the two. At the same time, a buckle can also be provided on the mounting seat 2221 to fix the sensor 221, to ensure that the controller body 2222 is firmly fixed on the mounting seat 2221, to avoid the controller body 2222 falling off under the action of external force, thereby affecting the control effect of the controller body 2222.

[0070] Optionally, the buckle portion 2222A may be a buckle with an elastic portion, or a protrusion provided with a spring, or other structures, and the present application does not impose any specific limitation on this.

[0071] In summary, in the range hood provided by the present application, the detection component 22 is arranged in the shell component 21, that is, the shell component 21 can protect the detection component 22 to prevent oil, smoke, water vapor, etc. from contacting the detection component 22, resulting in damage to the detection component 22, and further affecting the detection effect of the detection component 22. That is, by setting the detection component 22 in the shell component 21 and fixing it on the smoke hood 1, the detection reliability of the detection component 22 is improved, and the service life of the detection component 22 is also improved. At the same time, the shell component 21 is partially embedded and fixed in the installation cavity 1A, which avoids the problem of the shell component 21 falling off due to external force, improves the connection firmness between the shell component 21 and the smoke hood 1, thereby improving the connection firmness between the detection component 22 and the smoke hood 1, and then ensuring the detection reliability of the detection device 2.
