Description

Technical Field

[0002] Home kitchens, especially those in Chinese households, tend to produce a large amount of hot fumes and steam due to the heavy emphasis on stir-frying and deep-frying. To remove these fumes and steam, range hoods are typically installed. To ensure the prompt and rapid removal of these fumes, range hoods require high airflow rates, typically exceeding 1200m³ / h. Despite these high rated airflow rates, enclosed kitchens lack an effective source of supply air, significantly reducing the effective airflow and exhausting the fumes. Furthermore, polluted outdoor air can easily enter the kitchen through gaps in doors and windows, causing secondary pollution and backflow of odors from sewage and other sources, deteriorating kitchen air quality. Furthermore, stoves require oxygen for combustion, and a closed kitchen environment reduces oxygen levels, reducing combustion efficiency. Opening windows for ventilation also presents the problem of outdoor pollutants entering the kitchen, and irregular airflow outside the windows disrupts the extraction of fumes. In addition, the use of fire and electricity to cook and heat food in the kitchen causes the temperature in the kitchen to be high, especially in summer, when the temperature in the kitchen is very high, and a large amount of oil smoke is produced when frying, stir-frying, braising, etc. food.

[0060] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0061] The terms "a", "an", "the", "" are used to indicate that there are one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that there may be additional elements / components / etc. in addition to the listed elements / components / etc.

[0062] An air outlet component according to an embodiment of the present utility model, such as Figure 1-9 The air outlet assembly shown includes a guide housing 1, which has a cavity portion 10 with openings at both ends. The cavity portion 10 includes an air inlet cavity 101, an air guide cavity 102, and an air outlet cavity 103 in the direction of air flow. The cross section of the air inlet cavity 101 is circular, the cross section of the air outlet cavity 103 is rectangular, and the air guide cavity 102 is formed by multiple curved surfaces so that the air inlet direction of the air inlet cavity 101 and the air outlet direction of the air outlet cavity 103 are inclined. The "cross section" in this application refers to a section made perpendicular to the air flow direction, from Figure 1-6 It is not difficult to see that the cross-section of the air inlet cavity 101 is circular, and the cross-section of the air outlet cavity 103 is rectangular, that is, the air inlet of the guide shell 1 is circular, and the air outlet is rectangular. The air guide cavity 102 is a smooth transition shape formed by multiple curved surfaces, which increases the flow distance of the gas in the guide shell 1, makes the airflow between the air inlet cavity 101 and the air outlet cavity 103 flow smoothly, maximizes the airflow stability, ensures noise reduction, and provides a better blowing experience.

[0063] Furthermore, the air inlet of the air guide housing 1 is connected to a fresh air blower via a ventilation duct. This duct draws fresh air from the living room or outdoors, preferably the living room. Since the room temperature in the living room is generally lower than that in the kitchen, drawing fresh air from the living room toward the human body can help cool the body. Because the fresh air blower is internally equipped with a high-efficiency air filter, it can provide purified air. This not only prevents the problem of outdoor pollutants entering the kitchen and irregular airflow outside the window disrupting the fume extraction process, but also provides fresh, cool air to the kitchen, improving the user experience.

[0064] In a preferred embodiment of the present invention, Figure 1-6The flow area of the air guide cavity 102 shown in the figure first increases and then decreases along the airflow direction. In this way, as the flow area increases, the air flow becomes more uniform and smoother. In the second half of the airflow, the flow area is reduced to accelerate the airflow, thereby improving user comfort.

[0065] In a preferred embodiment of the present invention, Figure 1-9 The air guide cavity 102 shown includes an air cavity front wall 1021, an air cavity rear wall 1022 and two air cavity side walls 1023. The top of the air cavity front wall 1021 is connected to the bottom of the air inlet cavity 101, and the bottom end extends along the first curved surface to the inner side and lower side of the air guide cavity 102 and is connected to one long side of the top of the air outlet cavity 103; the air cavity rear wall 1022, the top of which is connected to the bottom of the air inlet cavity 101, and the bottom end extends along the second curved surface to the inner side and lower side of the air guide cavity 102 and is connected to the other long side of the top of the air outlet cavity 103; the two air cavity side walls 1023 are symmetrically connected between the air cavity front wall 1021 and the air cavity rear wall 1022, the top of each air cavity side wall 1023 is respectively connected to the bottom of the air inlet cavity 101, and the bottom end extends outward and downward and is connected to the short side of the top of the air outlet cavity 103; wherein, the width of the middle part of each air cavity side wall 1023 is greater than the width of its two ends. The first curved surface and the second curved surface in the present application are both Bezier surfaces, which form smooth and continuous curved surfaces respectively to guide the airflow in the air inlet cavity 101 smoothly and smoothly to the air outlet cavity 103, thereby greatly improving the smoothness of the airflow and ensuring noise reduction.

[0066] In a preferred embodiment of the present invention, Figure 1-6 The air outlet assembly shown also includes a mounting assembly 2, an air guide plate assembly 3 and a driving assembly 4. The mounting assembly 2 includes an air outlet channel corresponding to the air outlet cavity 103. The mounting assembly 2 is connected to the bottom of the guide housing 1. The bottom of the guide housing 1 is inserted into the air outlet channel. The air guide plate assembly 3 is inserted into the air outlet channel and is rotatably connected to the mounting assembly 2 to open or close the air outlet channel. The driving assembly 4 is connected to the mounting assembly 2 and the air guide plate assembly 3 to drive the air guide plate assembly 3 to open or close the air outlet channel. When the air outlet assembly is closed, the driving assembly 4 drives the air guide plate assembly 3 to rotate and close the air outlet end of the air outlet channel. When the air outlet assembly is opened, the driving assembly 4 drives the air guide plate assembly 3 to rotate within a certain angle range. The air guide plate assembly 3 can guide the gas in the air outlet channel and adjust the air outlet angle and air volume.

[0067] In a preferred embodiment of the present invention, Figure 1-4The mounting assembly 2 shown in FIG9 includes a mounting panel 21 and a mounting frame 22. The mounting frame 22 connects the mounting panel 21 and the air guide housing 1. The air guide plate assembly 3 and the air guide plate assembly 3 are respectively connected to the mounting frame 22. The mounting panel 21 is provided with an air outlet 211. The bottom of the mounting frame 22 is connected to the mounting panel 21 on the periphery of the air outlet 211. The bottom of the mounting frame 22 is provided with a first through hole 221 corresponding to the air outlet 211. The top of the mounting frame 22 is provided with a second through hole 222 corresponding to the air outlet end of the air guide housing 1. The passage connected in sequence along the second through hole 222, the first through hole 221 and the air outlet 211 forms an air outlet passage. When the air outlet assembly needs to be closed, the driving assembly 4 only needs to drive the air guide plate assembly 3 to rotate into the air outlet 211, thereby automatically closing the air outlet passage. Similarly, the driving assembly 4 can also drive the air guide plate assembly 3 to rotate and open the air outlet passage according to system instructions or user voice, key operation and other signals. In the present application, the mounting frame 22 and the mounting panel 21 can be connected by snap-fitting or bolting as shown in the figure, or by welding or other methods, which is not limited in the present application.

[0068] In addition, the mounting panel 21 can also be connected to a display light assembly 6, which is directly fixed to the air outlet panel by buckles and screws.

[0069] In a preferred embodiment of the present invention, Figure 1-4 The air guide plate assembly 3 shown in Figures 1 and 9 includes a flat plate 31, a curved plate 32, two connecting plates 33 and multiple air guide plates 36, the two connecting plates 33 are symmetrically distributed on both sides of the multiple flat plates 31 and the curved plate 32, that is, symmetrically distributed on both sides of the multiple air guide plates 36, wherein each connecting plate 33 is connected to the end of the flat plate 31 and the curved plate 32, the flat plate 31 is inserted into the air outlet channel for opening or closing the air outlet hole 211, and the curved plate 32 is arranged opposite to the flat plate 31; the flat plate 31, the curved plate 32 and the two connecting plates 33 are arranged to form an air guide channel, and the air inlet area of the air guide channel is larger than its air outlet area. Preferably, the air inlet area of the air deflector assembly 3 is 4 times or more the air outlet area. This ensures that the wind blown out of the deflector outlet flows completely straight into the air inlet of the air deflector assembly 3 within a certain angle range, and does not cause airflow to blow onto the outer side of the air deflector assembly 3. Then, as the flow area decreases, the airflow accelerates, which can avoid turbulence in the air deflector assembly 3 and the internal space of the mounting frame 22, thereby maximizing the smooth flow of airflow and reducing noise. In addition, a plurality of air deflectors 36 are also provided in the flow channel area within the air deflector assembly 3, which can make the airflow within the air deflector assembly 3 more uniform, provide a better blowing experience, and strengthen the structural strength of the air deflector assembly 3.

[0070] One of the connecting plates 33 is rotatably connected to the driving assembly 4, and the driving assembly 4 drives the entire air guide plate assembly 3 to rotate through the connecting plate 33. When the air outlet assembly is closed, the flat plate 31 covers the air outlet end of the air outlet hole 211, and the bottom surface of the air guide plate assembly 3 and the mounting panel 21 are coplanar.

[0071] In a preferred embodiment of the present invention, Figure 1-4 The outer side of each connecting plate 33 shown in Figure 9 is respectively connected to a rotating shaft 34, and the mounting frame 22 is provided with a rotating hole 223 corresponding to each rotating shaft 34. One end of the rotating shaft 34 is fixed to the connecting plate 33, and the other end passes through the rotating hole 223; the driving assembly 4 includes a motor 41, the housing of the motor 41 is connected to the mounting frame 22, and the motor shaft of the motor 41 is connected to one of the rotating shafts 34 to drive the air guide assembly 3 to rotate. The assembly of the air guide assembly 3 and the mounting frame 22 is achieved by the rotating shaft 34 and the rotating hole 223. The outer wall of the mounting frame 22 is provided with a mounting hole for fixing the housing of the motor 41. The circumferential rotating hole 223 of the motor 41 is connected to one of the rotating shafts 34. When the air outlet assembly is closed, the bottom surface of the mounting panel 21 is formed as shown below. Figure 2 A plane shown in FIG. and the current position state is maintained by the self-locking force of the motor 41. Figure 3 When the air outlet assembly is in the open state shown, the motor 41 rotates and drives the air guide plate assembly 3 to rotate synchronously, thereby opening the air outlet hole 211.

[0072] Preferably, a rotating sleeve is sleeved on the outer periphery of the other rotating shaft 34, that is, the rotating shaft 34 connected to the motor 41. The rotating sleeve is made of self-lubricating material, such as POM, which has little resistance with the rotating shaft 34, making the rotation smoother.

[0073] In a preferred embodiment of the present invention, Figure 1-4 The bottom of the rotating shaft 34 shown in FIG9 is fixedly connected to a limit block 35. The mounting frame 22 is provided with a first limit slot 224 corresponding to the limit block 35. The bottom of the first limit slot 224 is connected to the corresponding rotation hole 223. The limit block 35 is inserted into the first limit slot 224 from the rotation hole 223 to limit the rotation range of the air deflector assembly 3 to 0°~120°. The limit slot 224 is a "U"-shaped slot with the notch facing in the direction of the notch. The two groove walls of the limit slot 224 are used to limit the movement range of the limit block 35. The rotation range of the air deflector assembly 3 is 0°~120°. The rotation range of the air deflector assembly 3 is accurately limited to 0-120°. Due to the large rotation angle range of the air deflector assembly 3, air can be blown in more places in the kitchen, improving the user experience.

[0074] In a preferred embodiment of the present invention, Figure 1-5The outer periphery of the second through hole 222 shown in FIG9 is provided with a flange 225, the flow guide housing 1 is inserted into the interior of the flange 225 and abuts against the top end of the second through hole 222, and the flow guide housing 1 is snapped into the flange 225. In the present application, the outer periphery bottom of the flow guide housing 1 is connected to the second clip 17, and the flange 225 is provided with a snap hole 2251 corresponding to the second clip 17. When the flow guide housing 1 is inserted into the interior of the flange 225 and abuts against the top end of the second through hole 222, the second clip 17 snaps into the snap hole 2251, thereby completing the assembly of the flow guide housing 1 and the mounting frame 22. The structure is simple and installation and maintenance are convenient.

[0075] In a preferred embodiment of the present invention, Figure 1-4 The guide housing 1 and the mounting frame 22 shown in FIG9 are also provided with a fixing structure 5 for fixing the relative positions of the guide housing 1 and the mounting frame 22.

The mounting block 51 is located above the flange 225 and is fixed to the outer wall of the guide housing 1; the mounting column 52 is located on the periphery of the flange 225 and is fixed to the mounting frame 22. The mounting block 51 can abut against the flange 225 and the top of the mounting column 52. The mounting block 51 and the mounting column 52 are bolted together to achieve the fixation of the guide housing 1 and the mounting frame 22. Figure 1-8 As shown, the opposite side of the deflector shell 1 and the second clip 17 is connected to the mounting block 51. When the deflector shell 1 and the mounting shell are snapped together, the bottom surface of the mounting block 51 is located above the flange 225 and abuts against the top surface of the mounting column 52. The mounting block 51 and the mounting column 52 are bolted together to fix the deflector shell 1 and the mounting frame 22 as a whole, while avoiding the shaking of the deflector shell 1, which causes loud airflow noise and affects the user experience.

[0076] In a preferred embodiment of the present invention, Figure 1-8 The air guide housing 1 shown includes a first housing portion 11 and a second housing portion 12 that are arranged relative to each other. The first housing portion 11 and the second housing portion 12 can be arranged to surround a cavity portion 10, and the second housing portion 12 can be detachably connected to the first housing portion 11. Since the air guide cavity 102 in this application is not only required to expand the air guide area and stroke, but also to make the air flow direction of the air inlet cavity 101 and the air outlet cavity 103 inclined, such a requirement leads to a more complex structure of the air guide housing 1, especially the air guide cavity 102. The present application is simple to produce by dividing into the first housing portion 11 and the second housing portion 12, and different structures of the air guide housing 1 can be formed by combining the first housing portion 11 and the second housing portion 12 of different shapes, which has a wider range of applications.

[0077] In a preferred embodiment of the present invention, Figure 1-8One of the first and second housing portions 11, 12 is provided with a first snap 13, and the other is provided with a base 14 corresponding to the first snap 13, with the first snap 13 snapped onto the base 14. The first snap 13 in this application is a snap ring, which is mounted on the base 14 and affixed to the first and second housing portions 11, 12 to achieve a fixed connection, resulting in a simple connection structure. Furthermore, this application also provides a threaded block and a threaded column on one side of the first and second housing portions 11, 12 near the air inlet end. The connection between the threaded block and the threaded column further reinforces the first and second housing portions 11, 12, preventing gaps that could lead to gas leakage.

[0078] In a preferred embodiment of the present invention, Figure 6-8 A limiting structure 15 is provided between the connecting end of the first shell part 11 and the connecting end of the second shell part 12, so that the first shell part 11 and the second shell part 12 can be aligned and connected, simplifying the installation procedure and assembly process of the first shell part 11 and the second shell part 12, and improving production efficiency.

[0079] In a preferred embodiment of the present invention, Figure 6-8 The limiting structure 15 shown includes: a limiting protrusion 151 and a second limiting groove 152 corresponding to the limiting protrusion 151. The limiting protrusion 151 is connected to one of the first housing portion 11 and the second housing portion 12, and the second limiting groove 152 is connected to the other of the first housing portion 11 and the second housing portion 12. For ease of description, in this embodiment, the limiting protrusion 151 is provided on the first housing portion 11, and the second limiting groove 152 is provided on the second housing portion 12. The second limiting groove 152 is a first L-shaped groove. The limiting protrusion 151 and the end of the first housing portion 11 form a second L-shaped groove opposite to the first L-shaped groove. The first L-shaped groove and the second L-shaped groove are symmetrical to each other, so that the limiting protrusion 151 can be inserted into the notch of the second limiting groove 152 to achieve the alignment, connection and limiting of the first housing portion 11 and the second housing portion 12. Then, the first housing portion 11 and the second housing portion 12 can be snapped together. The connection structure is simple and easy to operate.

[0080] In a preferred embodiment of the present invention, Figure 6-8The limiting structure 15 shown also includes an arc-shaped support block 153, one end of which is connected to the inner periphery of one of the first shell part 11 and the second shell part 12, and the other end of the arc-shaped support block 153 extends toward the other of the first shell part 11 and the second shell part 12 and abuts against its inner periphery. For ease of description, this embodiment is described as the arc-shaped support block 153 being fixed to the inner periphery of the first shell part 11, which is not intended to limit the present application. The first shell part 11 and the arc-shaped support block 153 are equivalent to forming an "L"-shaped support groove, and the inner periphery of the second shell part 12 abuts against the outer periphery of the arc-shaped support block 153. When the first shell part 11 and the second shell part 12 are aligned and connected, the arc-shaped support block 153 can prevent one of the first shell part 11 and the second shell part 12 from falling off, and can also enable the first shell part 11 and the second shell part 12 to always maintain a fixed structure, avoiding deformation after long-term use, which affects the comfort of air outlet.
