[0017] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-7The present application will be further described in detail with reference to the embodiments.
[0018] First, it should be noted that in the description of this application, the use of directional terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for descriptive purposes and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0019] This application discloses an integrated range hood and cooktop unit. (Refer to...) Figure 1-6 As one embodiment of an integrated range hood and cooktop, the integrated range hood and cooktop includes a cooktop assembly 1 and a lower cabinet assembly 2, with the cooktop assembly 1 connected to the lower cabinet assembly 2. The integrated range hood and cooktop has a first inlet channel 21 and a second inlet channel 22, which are two independent inlet channels. The lower cabinet assembly 2 includes a cabinet body 23, a first suction device 24, and a second suction device 25. The cabinet body 23 has an exhaust channel for gas discharge. The suction channel of the first suction device 24 connects the first inlet channel 21 and the exhaust channel. The suction channel of the second suction device 25 connects the second inlet channel 22 and the exhaust channel. The portion of the inlet of the first inlet channel 21 adjacent to the second inlet channel 22 is defined as the acceleration zone. When both the first suction device 24 and the second suction device 25 are working, the gas velocity in the first inlet channel 21 is less than the gas velocity in the second inlet channel 22, and the gas at the inlet of the second inlet channel 22 can accelerate the gas in the acceleration zone into the first inlet channel 21.
[0020] In this application, by arranging the first inlet channel 21 and the second inlet channel 22 in the lower cabinet assembly 2, under the siphon effect, the gas at the inlet of the second inlet channel 22 can accelerate the gas in the acceleration zone into the first inlet channel 21, thereby increasing the gas flow rate at the inlet of the first inlet channel 21. Thus, the oil fume extraction efficiency of the integrated stove cabinet can be improved without changing the working power of the first suction device 24.
[0021] Specifically, when both the first suction device 24 and the second suction device 25 are working, the first inlet channel 21 serves as the main inlet channel of the integrated range hood and cooktop, and the second inlet channel 22 serves as the auxiliary inlet channel. Most of the gas drawn by the integrated range hood and cooktop enters the first inlet channel 21. The statement that "the first inlet channel 21 and the second inlet channel 22 are two independent inlet channels" can be understood as follows: the pipes corresponding to the first inlet channel 21 and the pipes corresponding to the second inlet channel are independent of each other. When both the first suction device 24 and the second suction device 25 are working, gas can be drawn through either the first inlet channel 21 or the second inlet channel 22. The first suction device 24 can be turned on independently, and the second suction device 25 can also be turned on independently. The opening or closing of the first suction device 24 and / or the second suction device 25 can be controlled according to the concentration of cooking fumes or the user's selection.
[0022] The cross-sectional area of the gas flow at the inlet of the first inlet channel 21 is larger than the cross-sectional area of the gas flow at the inlet of the second inlet channel 22.
[0023] Specifically, by setting the flow cross-sectional area at the inlet of the first inlet channel 21 to be larger than the flow cross-sectional area at the inlet of the second inlet channel 22, the effect of throttling and speeding up can be achieved.
[0024] In one implementation, see Figure 2 The first inlet channel 21 and the second inlet channel 22 are both formed in the cabinet 23; the inlet of the first inlet channel 21 and the inlet of the second inlet channel 22 are set closer to the rear side of the cabinet 23 than the front side of the cabinet 23; the inlet of the first inlet channel 21 and the inlet of the second inlet channel 22 are set along the length of the integrated stove and cabinet.
[0025] Specifically, the front side of the cabinet 23 can be understood as the side facing the user when using the integrated range hood and cooktop, and the rear side of the cabinet 23 can be understood as the side away from the user when using the integrated range hood and cooktop. The length direction of the integrated range hood and cooktop can be understood as follows: when in use, the line connecting the side of the integrated range hood and cooktop facing the user and the side away from the user is the width direction of the integrated range hood and cooktop; the line connecting the remaining two sides of the integrated range hood and cooktop is the length direction of the integrated range hood and cooktop. It should be understood that the aforementioned length direction does not limit the dimension of the integrated range hood and cooktop in the length direction to be greater than its dimension in the width direction.
[0026] In another implementation, see Figure 3 and Figure 4The integrated cooktop also includes a head unit 3, which is connected to the lower cabinet unit 2. At least a portion of the first inlet channel 21 and at least a portion of the second inlet channel 22 are formed in the head unit 3. At least a portion of the projection of the inlet of the first inlet channel 21 in the vertical plane coincides with the projection of the inlet of the second inlet channel 22 in the vertical plane. In this way, through the siphon effect, the gas at the inlet of the second inlet channel 22 can accelerate the gas flow rate at the inlet of the first inlet channel 21, thereby improving the smoke extraction efficiency of the integrated cooktop.
[0027] Specifically, the head assembly 3 and the lower cabinet assembly 2 can be fixedly connected, movably connected, or detachably connected. When the head assembly 3 and the lower cabinet assembly 2 are fixedly connected, the connection method can be welding, connection by fasteners, integral molding, etc. When the head assembly 3 and the lower cabinet assembly 2 are movably connected, the head assembly 3 can be at least partially housed in the lower cabinet assembly 2. When the head assembly 3 and the lower cabinet assembly 2 are detachably connected, the head assembly 3 can be installed in the lower cabinet assembly 2 as needed. The aforementioned "at least a portion of the first inlet channel 21 is formed in the head assembly 3" can be understood as follows: in one embodiment, the pipe corresponding to the first inlet channel 21 can be partially formed in the head assembly 3 and the other part formed in the lower cabinet assembly 2 or other components; in another embodiment, the pipe corresponding to the first inlet channel 21 can also be entirely formed in the head assembly 3.
[0028] The head assembly 3 includes a head body and a baffle 32, which are connected. The head body has a smoke inlet chamber 33, which constitutes at least a portion of the first flow channel 21. The inlet of the smoke inlet chamber 33 constitutes the inlet of the first flow channel 21. The head assembly 3 also includes a flow concentrator 34, which is located behind the baffle 32 and is connected to the head body or the baffle 32. The flow concentrator 34 has an exhaust port 35, which constitutes the inlet of the second flow channel 22. The flow concentrator 34 has a flow channel, which constitutes at least a portion of the second flow channel 22.
[0029] In one implementation, see Figure 4 The head of the current collector 34 is elongated, and the air extraction hole 35 is formed on the head of the current collector 34; of course, in another embodiment, refer to Figure 5 The surface of the head of the flow collector 34 is curved, and the air extraction hole 35 is formed on the surface of the head of the flow collector 34. This allows the air extraction hole 35 to be formed in various directions on the surface of the head of the flow collector 34, thereby accelerating the entry of more gas near the inlet of the second inlet channel 22 into the first inlet channel 21 through the siphon effect.
[0030] The cabinet 23 has a receiving cavity 231, and the first suction device 24 and the second suction device 25 are located in the receiving cavity 231.
[0031] Specifically, the first suction device 24 and the second suction device 25 are both located in the receiving cavity 231 inside the cabinet 23, so that the first suction device 24 and the second suction device 25 do not need to occupy the external space of the cabinet 23, which improves the compactness of the overall structure of the integrated range hood and stove, and also helps to improve the aesthetics of the integrated range hood and stove.
[0032] The second suction device 25 includes an inlet channel 251 and an outlet channel 252. The inlet of the inlet channel 251 is connected to the second inlet channel 22. The outlet of the outlet channel 252 is connected to the exhaust channel of the integrated cooktop unit. Along the gas outflow direction in the outlet channel 252, the cross-sectional area of the gas flow in the outlet channel 252 gradually decreases. This helps to increase the gas flow velocity in the outlet channel 252, thereby accelerating the gas discharge.
[0033] Specifically, the gradual reduction can be a continuous reduction across the entire region, or a gradual reduction within a specific region. As the fluid passes through the narrowed flow cross-section, the fluid velocity increases, thereby accelerating the rate at which the second suction device 25 discharges gas.
[0034] The lower cabinet assembly 2 also includes an air outlet seat 26, which is fixedly connected to the cabinet body 23. The air outlet seat 26 has a branch channel 261, which constitutes at least part of the exhaust channel of the lower cabinet assembly 2. Along the gas outflow direction in the branch channel 261, the cross-sectional area of the branch channel 261 gradually decreases and then gradually increases. The channel corresponding to the portion of the branch channel 261 with a smaller cross-sectional area is connected to the outlet of the exhaust channel 252. This further helps to increase the gas flow velocity in the branch channel 261, thereby accelerating the gas discharge.
[0035] Along the outflow direction of the gas in the branch channel 261, the branch channel 261 is sequentially formed with a contraction section 262 and a diffusion section 263. The cross-sectional area of the contraction section 262 gradually decreases in the direction of gas flow, and the cross-sectional area of the diffusion section 263 gradually increases in the direction of air flow. An arc-shaped transition structure 264 is formed at the connection between the contraction section 262 and the diffusion section 263. An inlet section 265 connected to the outlet of the gas outlet channel 252 is also formed upstream of the contraction section 262 in the branch channel 261.
[0036] Specifically, an arc-shaped transition structure 264 is formed at the connection between the contraction section 262 and the diffusion section 263 to avoid irregular airflow impact, improve the stability of airflow passage, and reduce the possibility of airflow swerving.
[0037] The integrated cooktop unit includes only one exhaust channel 27. The air outlet 26 has a main channel 28. The main channel 28 constitutes part of the exhaust channel 27 of the lower cabinet component 2. The suction channel of the first suction device 24 is connected to the main channel 28. The channel corresponding to the portion with reduced cross-sectional area in the branch channel 261 is connected to the outlet of the suction channel of the second suction device 25 and the main channel 28.
[0038] Specifically, during exhaust, since the channel corresponding to the portion with reduced cross-sectional area in the branch channel 261 connects the outlet of the suction channel of the second suction device 25 and the main channel, the flow rate of the gas discharged by the second suction device 25 is accelerated, thereby accelerating the rate at which the suction channel of the first suction device 24 discharges gas, and improving the overall rate at which the integrated stove cabinet exhausts gas through the external exhaust channel.
[0039] It should be noted that the above embodiments are only used to illustrate this application and are not intended to limit the technical solutions described in this application. Although this specification has described this application in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to this application. All technical solutions and improvements that do not depart from the spirit and scope of this application should be covered within the scope of the claims of this application.
