Detailed implementation manners

[0034] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to 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] In the kitchen, there is usually an oil fume extractor, for example, top suction, side suction, low suction (integrated stove type), Chinese style, tower type, top side double suction, bottom side double suction and other types of oil fume extractors, to suck the oil fume gas in the kitchen into the machine body and discharge it outdoors. With the further improvement of the performance of the oil fume extractor, sensors are usually also provided in the oil fume extractor to detect the environmental state of the oil fume extractor. However, the environment where the oil fume extractor is located is usually an oil fume environment state accompanied by oil stains, oil fume and water vapor, resulting in the sensor being possibly contaminated by oil stains during use, thereby affecting the detection accuracy of the sensor. After oil fume 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 collecting hood assembly and a range hood. The housing assembly in the smoke collecting hood assembly can protect the detection assembly, so as to avoid problems such as oil stains, oil fumes, water vapor, etc. contacting the detection assembly, resulting in damage and failure of the detection assembly. At the same time, a part of the housing assembly is embedded and fixed in the installation cavity, which improves the connection firmness between the housing assembly and the smoke collecting hood, thereby improving the connection firmness between the detection assembly and the smoke collecting hood, and further ensuring the detection reliability of the detection device.

[0037] The following provides an exemplary introduction to the smoke collecting hood assembly and the range hood provided by the present application with reference to the accompanying drawings.

[0038] The embodiments of the present application provide a range hood, which includes a smoke collecting hood assembly and a fan assembly. A smoke cavity is provided in the smoke collecting hood assembly. The fan assembly is located above the smoke collecting hood assembly, and the fan assembly is provided with an air outlet cavity communicating with the smoke cavity. When the range hood works, the range hood will suck the oil fume gas in the target environment (such as the kitchen) into the smoke cavity in the smoke collecting hood assembly, and then discharge the oil fume gas in the smoke cavity to the outside through the air outlet cavity. Here, it is worth understanding that a fan and a pneumatic device can be provided in the fan assembly. Both the fan and the pneumatic device are located in the air outlet cavity. When the range hood works, the pneumatic device will drive the fan to rotate to discharge the oil fume gas in the air outlet cavity to the outside. Other structures can also be provided in the fan assembly. In this regard, the present application does not make specific limitations.

[0039] In order to be able to detect the oil fume environment state of the kitchen in real time and accurately control the working state of the smoke collecting hood assembly to better maintain the kitchen environment, in one example, as Figure 1 shown, the smoke collecting hood assembly can include a smoke collecting hood 1 and a detection device 2. An installation cavity 1A is provided in the smoke collecting hood 1. A part of the detection device 2 is located in the installation cavity 1A and is fixedly connected to the smoke collecting hood 1, and another part 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 (such as the kitchen) and correspondingly adjust the working state of the range hood.

[0040] Here, it is worth noting that the temperature collected by the detection device 2 can be the temperature of the cookware in the kitchen, the temperature where the stove is located, and the temperature above the stove, that is, the detection device 2 can collect and detect the temperature of all places between the stove and the range hood above. The concentration collected by the detection device 2 can be the oil fume concentration and odor concentration in the kitchen, and can also be other temperatures or concentrations in the oil fume environment. In this regard, the present application does not make specific limitations.

[0041] In order to enable the detection device 2 to collect the temperature and / or concentration of the kitchen and correspondingly adjust the working state of the range hood, in one example, please refer to Figures 2 to 3, the detection device 2 may include a housing assembly 21 and a detection assembly 22. A part of the housing assembly 21 is located in the installation cavity 1A and fixedly connected to the smoke hood 1, and another part of the housing assembly 21 is located outside the installation cavity 1A. The detection assembly 22 is arranged in the housing assembly 21. The detection assembly 22 is used to collect temperature and / or concentration and correspondingly adjust the working state of the range hood to better maintain the kitchen environment. In this example, the detection assembly 22 is arranged in the housing assembly 21, that is, the housing assembly 21 can play a protective role for the detection assembly 22 to avoid contact between oil stains, fumes, water vapor, etc. and the detection assembly 22, resulting in damage and failure of the detection assembly 22, and further affecting the detection effect of the detection assembly 22. That is, by arranging the detection assembly 22 in the housing assembly 21 and fixing it on the smoke hood 1, the detection reliability of the detection assembly 22 is improved, and at the same time, the service life of the detection assembly 22 is also extended, so that the detection assembly 22 can accurately control the working state of the smoke hood assembly based on the detected oil fume environment state of the kitchen to better maintain the kitchen environment. At the same time, a part of the housing assembly 21 is embedded and fixed in the installation cavity 1A, avoiding the problem of the housing assembly 21 falling off due to external force, improving the connection firmness between the housing assembly 21 and the smoke hood 1, thereby improving the connection firmness between the detection assembly 22 and the smoke hood 1, and further ensuring the detection reliability of the detection device 2.

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

[0043] In this example, the housing assembly 21 can be embedded and fixed in the installation cavity 1A through the fixing bracket 211 to ensure the firm connection between the housing assembly 21 and the smoke collecting hood 1. At the same time, the fixed housing 212 is fixedly connected to the fixing bracket 211 and protrudes from the installation cavity 1A, so that the detection device 2 installed in the fixing bracket 211 can collect the temperature and / or concentration in the kitchen to ensure the collection and detection reliability of the detection device 2. Secondly, the side of the fixed housing 212 protruding from the installation cavity 1A is clamped with the smoke collecting hood 1, that is, there is no gap between the side of the fixed housing 212 and the smoke collecting hood 1, so as to prevent oil stains, lampblack, water vapor, etc. from entering the housing assembly 21 through the installation cavity 1A, resulting in damage and failure of the detection component 22 in the housing assembly 21, and then 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, lampblack, water vapor, etc. converge in the smoke collecting hood 1 through the installation cavity 1A, resulting in serious pollution of the smoke collecting hood 1 and inconvenient cleaning.

[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 fixing bracket 211 can include a first bracket 2111 and a second bracket 2112. The first bracket 2111 is at least disposed around one side of the fixed housing 212 to achieve a fixed connection with the fixed housing 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. Fasteners such as bolts and screws can be used to fix the second bracket 2112 in the installation cavity 1A through the threaded hole 2112A. In this way, the fixing bracket 211 can achieve a fixed connection with the smoke collecting hood 1 through the second bracket 2112, and at the same time achieve a fixed connection with the fixed housing 212 through the first bracket 2111 to ensure the firm connection between the smoke collecting hood 1, the fixing bracket 211 and the fixed housing 212. At the same time, fasteners such as bolts and screws are hidden in the smoke collecting hood 1, avoiding the problem that the exposed fasteners affect the aesthetics.

[0045] Optionally, in order to improve the firm connection between the fixing bracket 211 and the fixed housing 212, the first bracket 2111 can be disposed around the fixed housing 212. In order to save manufacturing costs, the first bracket 2111 can be disposed only on one side of the fixed housing 212. For this, the present application does not make specific restrictions.

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

[0047] In this example, since the fixing housing 212 is a three-dimensional structure rather than a planar structure, therefore, in one example, please refer to Figures 7 to 9 , the fixing bracket 211 usually further includes a bending portion 2114. One end of the bending portion 2114 is fixedly connected to the first bracket 2111, and the other end of the bending portion 2114 is fixedly connected to the second bracket 2112. In this way, the fixing connection between the first bracket 2111 and the second bracket 2112 located in different planes can be realized through the bending portion 2114. The bending angle and size of the bending portion 2114 can be set based on the size of the fixing housing 212. Optionally, the first bracket 2111, the bending portion 2114, and the second bracket 2112 can be an integrally formed structure by casting or independent structures, which can be specifically set according to actual needs. In this regard, the present application does not make specific limitations.

[0048] Optionally, the fixing bracket 211 can be made of plastic materials, such as acrylonitrile-butadiene-styrene copolymer (ABS), polycarbonate (PC), polypropylene (PP), and thermoplastic polyurethanes (TPU). Plastic materials are light, have good toughness, and low cost.

[0049] In order to enable the detection component 22 to be fixed in the fixing housing 212, in one example, as Figure 10 shown, a receiving groove 212A is provided in the fixing housing 212 for receiving 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 generally cylindrical, the inside 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 fixing housing 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, or 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. In this regard, the present application does not make specific limitations.

[0050] After the detection component 22 has been used for a period of time, it needs to be overhauled and replaced. For the convenience of disassembly and assembly, the opening of the receiving groove 212A can face 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, making the disassembly and assembly simple and convenient.

[0051] To further improve the firmness of the detection component 22 fixed in the fixed housing 212, please refer to Figures 10 to 11 , an elastic member 212C can also be provided on the groove wall of the receiving groove 212A, and a groove 22A can be provided on the housing of the detection component 22. The elastic member 212C and the groove 22A are correspondingly clamped to realize the connection between the detection component 22 and the fixed housing 212. The connection firmness is relatively high, and it is convenient for disassembly and assembly. At the same time, through the corresponding clamping of the elastic member 212C and the groove 22A, the detection component 22 can also be limited, so that the detection component 22 can be limited to a preset position in the fixed housing 212. Here, the preset position can be referred to as the best position where the detection component 22 can perform collection and detection to ensure the collection and detection reliability of the detection component 22.

[0052] Optionally, the elastic member 212C can be a buckle with an elastic part, or a protruding member provided with a spring, or other structures. In this regard, the present application does not make specific limitations.

[0053] To save manufacturing costs, only one elastic member 212C can be provided on the groove wall of the receiving groove 212A. To improve the firmness of the detection component 22 fixed in the fixed housing 212, multiple elastic members 212C can be provided on the groove wall of the receiving groove 212A at intervals. At the same time, multiple grooves 22A are also correspondingly provided on the housing of the detection component 22. The multiple elastic members 212C and the multiple grooves 22A are correspondingly clamped one by one to improve the firmness of the detection component 22 fixed in the fixed housing 212.

[0054] Optionally, when the height of the groove wall of the receiving groove 212A is the same as the height of the detection component 22, an elastic member 212C can be provided on the groove wall of the receiving groove 212A. When the height of the groove wall of the receiving groove 212A is lower than the height of the detection component 22, a part of the groove wall of the receiving groove 212A can be extended to form an elastic member 212C. In this regard, the present application does not make specific limitations.

[0055] Optionally, multiple limiting ribs can also be provided on the groove wall of the receiving groove 212A. The multiple limiting ribs can limit and fix the detection component 22 to further improve the firmness of the detection component 22 fixed in the fixed housing 212. Other limiting or fixing structures can also be provided on the receiving groove 212A based on the structure of the detection component 22. In this regard, the present application does not make specific limitations.

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

[0057] Optionally, the fixed housing 212 can be made of plastic materials, such as acrylonitrile-butadiene-styrene copolymer, polycarbonate, polypropylene, and thermoplastic polyurethane. Plastic materials are light, have good toughness, and low cost. The fixed housing 212 can also be made of other materials such as metal. In this regard, the present application does not make specific limitations.

[0058] Optionally, the fixed bracket 2111 and the fixed housing 212 can be an integrally formed structure by casting or an independent structure, which can be specifically set according to actual needs. In this regard, the present application does not make specific limitations.

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

[0060] In this example, the sensor 221 can collect and detect the temperature and / or concentration in the kitchen in real time to accurately know the oil fume condition in the kitchen, accurately judge the oil fume environment state in the kitchen, and send information such as the collected temperature and / or concentration 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 to improve the working reliability of the range hood, thereby better maintaining the kitchen environment.

[0061] For example, when the sensor 221 detects that the temperature in the kitchen is higher than the preset temperature, the preset temperature at this time can 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 in 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, if the range hood needs to work to maintain the kitchen environment, 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 in 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 smoking intensity levels: low, medium, and high. When the sensor 221 detects that the oil fume concentration in the kitchen is higher than the maximum preset concentration, the kitchen environment is poor at this time, and the oil fume needs to be discharged in time. Then the controller 222 can switch the range hood to the high gear to quickly suck and discharge the oil fume to maintain the kitchen environment. After the range hood operates at the high gear for a period of time, the sensor 221 will detect that the oil fume concentration in the kitchen is lower than the maximum preset concentration and higher than the minimum preset concentration. At this time, the kitchen environment has been relieved, and the controller 222 can switch the range hood to the low gear 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 information such as temperature and / or concentration to the controller 222. A processing program can be set inside the controller 222 to process the received information to obtain the working state that needs to be switched, and correspondingly switch the working state of the range hood. 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 that needs to be switched, and send an electrical signal representing the working state that needs 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 this electrical signal. This application does not make specific restrictions on this.

[0064] The specific installation position and quantity of the sensor 221 can be set according to actual requirements. For example, in order to save manufacturing costs, only one sensor 221 can be set. 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 for collecting and detecting temperature and concentration, the number of sensors 221 is at least one. 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 the detection accuracy.

[0065] In one example, when the number of sensors 221 is multiple, the bottom wall of the receiving groove 212A may include at least two mounting planes. The multiple sensors 221 are distributed on at least two mounting planes to collect and detect temperature and concentration at different angles. Exemplarily, as Figure 13 shown, the number of sensors 221 can be set to three, namely the first sensor 221a for detecting temperature, the second sensor 221b for detecting the concentration of cooking fumes, and the third sensor 221c for detecting the concentration of odors. The bottom wall of the receiving groove 212A correspondingly includes two mounting planes. At this time, three through holes 212B are correspondingly provided on the two mounting planes, and the sizes and shapes of the three through holes 212B respectively correspond to the first sensor 221a, the second sensor 221b, and the third sensor 221c one by one. One of the mounting planes faces the cooking stove, and the first sensor 221a and the second sensor 221b can be adjacent and distributed on the mounting plane facing the cooking stove to improve the detection accuracy of temperature and the concentration of cooking fumes. The third sensor 221c can be located on the other mounting plane.

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

[0067] Here, it is worth noting that when the bottom wall of the receiving groove 212A includes a plurality of mounting planes, that is, when the bottom wall of the receiving groove 212A is an irregular structure, the first bracket 2111 disposed around the fixed housing 212 is equivalent to being disposed around the four sides of the bottom wall of the receiving groove 212A, that is, the first bracket 2111 can also be an irregular structure.

[0068] In one example, as Figure 14 shown, the controller 222 may include a mounting base 2221 fixed within the receiving groove 212A, and the controller body 2222 is fixed to the mounting base 2221 and electrically connected to the sensor 221, for receiving the temperature and / or concentration collected by the sensor 221, and correspondingly adjusting the operating state of the range hood. In this example, the controller body 2222 may be fixed within the fixed housing 212 through the mounting base 2221, and control circuits, processing chips and other structures may be provided on the controller body 2222 to achieve the reception of the temperature and / or concentration collected by the sensor 221, and the corresponding adjustment of the operating state of the range hood.

[0069] To ensure the firmness of the controller body 2222 fixed to the mounting base 2221, in one example, one of the controller body 2222 and the mounting base 2221 is provided with a buckle, and the other is provided with a groove, and the buckle is snapped into the groove to achieve a firm connection between the controller body 2222 and the mounting base 2221. Exemplarily, as Figure 14 shown, a buckle portion 2222A is provided on the controller body 2222, and a groove is provided at the corresponding position on the mounting base 2221, and the buckle portion 2222A is snapped into the groove to achieve their fixed connection. At the same time, a buckle may also be provided on the mounting base 2221 to fix the sensor 221, ensuring the firmness of the controller body 2222 fixed to the mounting base 2221, and avoiding the problem that the controller body 2222 falls 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 part, or a protruding member provided with a spring, or other structures. In this regard, the present application does not make specific limitations.

[0071] In summary, in the range hood provided by the present application, the detection component 22 is arranged inside the housing component 21. That is, the housing component 21 can protect the detection component 22 to avoid the problems that oil stains, oil fumes, water vapor, etc. come into contact with the detection component 22, resulting in damage and failure of the detection component 22, and further affecting the detection effect of the detection component 22. That is, by arranging the detection component 22 inside the housing component 21 and fixing it on the smoke collecting hood 1, the detection reliability of the detection component 22 is improved, and at the same time, the service life of the detection component 22 is also extended. At the same time, part of the housing component 21 is embedded and fixed in the installation cavity 1A, avoiding the problem that the housing component 21 falls off due to external force, improving the connection firmness between the housing component 21 and the smoke collecting hood 1, thereby improving the connection firmness between the detection component 22 and the smoke collecting hood 1, and further ensuring the detection reliability of the detection device 2.
