Abstract
Description
Technical Field
[0001] This invention belongs to the field of kitchen facilities and equipment technology. Background Technology
[0002] Currently, after years of use, all kitchen equipment and facilities are covered in grease and steam. Besides gas stoves producing fumes, rice cookers, electric kettles, slow cookers, and other appliances like sinks generate grease and steam. This grease and steam not only pollute the kitchen air but also indirectly accelerates the aging process of kitchen equipment and cabinets. Existing range hoods are generally 900mm or shorter, limiting the space they can cover around the stove. Therefore, while most fumes are removed, some naturally drift into the air. The cabinet under the sink is a major problem area; because it's sealed, condensation and odors from the sink drainpipe severely damage the cabinet and the overall kitchen environment. With societal progress, we should use more clean energy (electricity). Gas stoves not only blacken pots and pans but also gradually deplete this non-renewable resource. Therefore, with the development of clean energy (electricity), we should try to use more electrical appliances (such as induction cookers). Summary of the Invention
[0003] This invention relates to a kitchen accessory, specifically to an upgraded and improved range hood with increased length, different arrangements of gas stove burners and induction cookers, and an increased overall length of the gas stove panel. It also relates to a combination of features such as exhaust, ventilation, lighting, and shelving above the sink and other appliances; real-time monitoring of temperature and humidity inside the sink cabinet; exhaust; and infrared sterilization. These features aim to solve the aforementioned technical problems.
[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a kitchen accessory, including a range hood body, the length of which is longer than that of existing range hoods. A smoke-gathering plate is provided at each of the left and right ends of the air inlet of the range hood. An air outlet is opened on the bottom plane of the range hood body on the upper outer side of the smoke-gathering plate. The smoke-gathering plate has two functions: first, to prevent the smoke generated during the use of the gas stove from spreading to the left and right; second, to guide the air blown out of the air outlet to a position closer to the countertop, where it diffuses to form an air curtain. The formation of the air curtain prevents low-latitude fumes from spreading to both sides. The air diffused by the air curtain, along with the fumes, will be drawn together by the suction of the range hood. The exhaust vent is removed; another ceiling-mounted air vent in the kitchen (referred to as the ceiling air vent) is located on the ceiling directly above the range hood. The ceiling air vent is a combination of the air vent and the lighting fixture. The ceiling air vent is rectangular, with a length roughly the same as the range hood and a width of 300mm. The air blown out by the ceiling air vent forms a downward airflow zone above the range hood and the people. The function of this airflow zone is to draw away the oil fumes that would spread forward and upward along with the air blown out by the air vent, which are then sucked away by the suction of the range hood. The air blown out by the range hood vent and the ceiling air vent both come from fresh air outside the kitchen (e.g., outdoors, living room, dining room, etc.).
[0005] The decorative cover of the range hood body is designed to extend to the ceiling. A notch is designed at the upper rear corner of the decorative cover to avoid obstructing the kitchen ceiling's internal corner line. A flexible plastic trim is installed at the notch, which can be cut to fit the shape of the exposed internal corner line. The back of the decorative cover is covered with flame-retardant and shock-absorbing materials. Inside the decorative cover is the inner wall of the range hood body. Inside the inner wall is another inner liner, with a number of holes in its wall. Multiple sets of V-shaped spacers separate the inner wall and the inner liner, forming multiple through-layer cavities. The V-shaped spacers are fixed to the outer wall of the inner liner, and the bottom of the V-shaped spacers is open (see appendix for details). Figure 3 The inner liner contains a volute centrifuge and a range hood silencing chamber. The volute centrifuge is located in the upper part of the inner liner cavity, and the range hood silencing chamber is located in the lower part of the inner liner cavity. The silencing chamber is equipped with multiple silencing meshes, which are shaped like the Chinese character (∧). The silencing meshes have staggered holes, and the overall smoke exhaust flow rate of the staggered holes is greater than or equal to the smoke exhaust flow rate when the power of the volute centrifuge is at its maximum value.
[0006] The top of the range hood body is simply a bend connecting pipe. The lower end of the bend connecting pipe is connected to the volute centrifuge, and the upper end is connected to the range hood check valve. The bend connecting pipe replaces the traditional range hood check valve. The range hood check valve of this invention is designed to be square, and the valve plate is also square (even if the check valve in the existing solution is square, its two ends can be transformed into round interfaces as needed). The valve plate is opened by the transmission gear of the motor driving the gear at one end of the transmission shaft on the valve plate to realize the opening and closing of the valve plate. The valve plate is fully open when open. The gear of the check valve motor and the gear of the valve plate transmission shaft are not a full-tooth design (referred to as half-tooth). The number of meshing teeth of the gears is sufficient to realize the full opening and full closing of the valve plate. The function and structure of the check valves matched with other kitchen equipment are similar to the above-mentioned range hood check valve.
[0007] The invention uses only one backflow preventer between the range hood body and the main kitchen exhaust duct.
[0008] The range hood body is now suspended from the kitchen wall using a parallel hanger, instead of the traditional drop hook.
[0009] The pipe fittings and exhaust pipes used with the range hood are square or round; the cross-sectional inner diameter area of the exhaust pipe is greater than the cross-sectional inner diameter area of the largest existing round exhaust pipe with a diameter of 200mm; the exhaust pipes and other related facilities and equipment located above the ceiling will be wrapped with flame-retardant materials and equipped with special hanging rods to suspend them from the kitchen ceiling.
[0010] The gas stove is a combination of burners and induction cookers; there are several possible arrangements: the first arrangement is two burners and one induction cooker, with the two burners side by side and the induction cooker to the left of the burners; the second arrangement is two burners and one induction cooker, with the two burners side by side and the induction cooker to the right of the burners; the third arrangement is one burner and two induction cookers, with the burner in the middle and the induction cookers to the left and right of the burner. The control buttons for the burners and induction cookers are separate from the gas stove, so that the gas stove panel and the surrounding countertop have no other accessories that would hinder cleaning, making cleaning easier and reducing the risk of accidentally activating the control buttons while wiping the panel. The control panel for the burners and induction cookers is located between the top of the cabinet door and the countertop, directly below the gas stove, and has ventilation holes.
[0011] The front of the range hood (the control panel and surrounding area) is designed with a snap-fit anti-collision device that matches the area where the human head is most likely to collide with the range hood. The induction cooktop panel of the gas stove is also equipped with a movable protective pad. The mechanical control switches of the burner are also equipped with protective covers. All of the above anti-collision devices, protective pads, and protective covers are made of flame-retardant plastic.
[0012] The kitchen sink, rice cooker, and other appliances that generate fumes and steam during use are designed with one or more exhaust devices (referred to as small and large top-mounted exhaust fans). The small and large top-mounted exhaust fans can also be designed as a combination to effectively cover the facilities and appliances placed on the left and right countertops of the sink. The small and large top-mounted exhaust fans are a combination of exhaust, lighting, and storage racks. This combination can be hung on the wall individually, or it can be installed in a concealed manner under the kitchen wall cabinets, or it can be clipped to the ceiling. Different styles can be made to match the needs of different kitchen scenarios.
[0013] The kitchen sink is located directly below the base cabinet, which is equipped with facilities and equipment (referred to as "integrated panel") that include real-time temperature and humidity monitoring, electronic ultrasonic rodent and cockroach repellency, ventilation, and infrared disinfection and sterilization.

[0026] Example 1, as shown in the attached document Figure 1The elevation view of the kitchen equipment is shown. This invention provides a kitchen equipment system including a range hood, gas stove, small top-mounted suction cup 2, large top-mounted suction cup 4, integrated panel 6, control panel 9, etc. The small top-mounted suction cup 2 and large top-mounted suction cup 4 are described below as being installed concealed within the kitchen wall cabinets. The small top-mounted suction cup 2 is above the rice cooker 1, the sink is to the right of the rice cooker, and the large top-mounted suction cup 4 is above the sink. Behind the large top-mounted suction cup 4 is a mechanically installed shelf 7. Directly below the sink is the base cabinet of the kitchen cabinet. The back panel of the base cabinet (or on the wall behind the cabinet) features the integrated panel 6, which integrates functions such as real-time temperature and humidity monitoring, electronic ultrasonic rodent and cockroach repellency, exhaust, and infrared disinfection and sterilization. The integrated panel 6 is rectangular. The lower left side houses the exhaust device, the upper part is the infrared device, and the right side of the panel is the area for temperature, humidity, and electronic rodent and cockroach repellent devices. The temperature, humidity, and electronic ultrasonic rodent and cockroach repellent devices on the integrated panel 6 can be controlled by a switch to achieve full-time operation and shutdown. The infrared disinfection and sterilization device is located on the upper left side of the control panel 6 and is rectangular. The exhaust is located on the lower left side of the control panel 6 and is rectangular. The front of the exhaust is a snap-on perforated panel, and the back has a 50mm exhaust connection port that connects to the pre-embedded pipe 3. The upper interface 5 of the pre-embedded pipe 3 (the pre-embedded pipe shown in the attached diagram is a vertical pre-embedded pipe; the specific direction of the pre-embedded pipe should be determined according to the actual kitchen scenario) is located above the kitchen ceiling.Interface 5 includes the small ceiling suction 2, the large ceiling suction 4, and the pre-embedded pipe 3, all located on the kitchen ceiling. Interface 5 connects to check valve interface 14 (check valve interface 14 contains three separate check valve interfaces; the function of check valve 14 is the same as that of range hood check valve 12). Check valve 15 (also containing three independent check valves) connects to a four-way adapter, which in turn connects to a fan 16. The air outlet of fan 16 connects to the range hood exhaust duct via a pipe, discharging the fumes and steam generated by appliances such as rice cooker 1, sink, etc., into the main exhaust duct. A fan 16 also has a... An independent fan is used to draw fresh air from outside the kitchen (meaning outdoors, the living room, or the dining room) and deliver it to the range hood's outlet and ceiling-mounted outlet via a connection to the fan, ductwork, and air supply vent. The range hood's backflow preventer 12's outlet is connected to the exhaust duct, which in turn connects to the main kitchen exhaust duct. The range hood's backflow preventer 12's inlet is connected to the elbow exhaust duct, which in turn connects to the range hood itself. Ceiling-mounted equipment is suspended from the kitchen ceiling using suspension rods 17. All equipment surfaces are covered with flame-retardant material 13. Below the flame-retardant material 13 label is the range hood itself, and the upper part of the range hood is covered with oil fume extractor. The exhaust chamber has a lower section called the fume hood, while the upper section, from the outside in, consists of a decorative cover, an inner wall, an inner liner, and inside the inner liner, a volute centrifuge and a sound-absorbing mesh. The decorative cover extends to the ceiling, and its back is covered with flame-retardant and shock-absorbing material. The decorative cover conceals the inner wall, and its height is approximately 50mm-150mm higher than the inner wall. The inner wall is a square cylindrical structure composed of a front wall, a rear wall, a left wall, and a right wall. A 30mm gap is left between the rear wall and the kitchen wall. At the top of the inner wall is a fixed partition with a square hole for the volute centrifuge to exhaust air. The perimeter of the hole has mounting holes for the volute centrifuge. The partition extends towards... The partition extends 25mm backward. A duct hole for the main air supply pipe of the range hood is located in the middle of the extended rear section. The left and right ends of the extended rear section are where the parallel hangers are suspended. Anti-slip grooves are provided on the bottom surface of this area, and a fixing screw hole matching the parallel hanger is also provided. Inside the inner wall is the inner liner, a square barrel-shaped body that matches the inner wall. A shock-absorbing rubber strip is installed at the top of the inner liner, contacting the partition. The bottom of the inner liner has an outward-facing L-shaped fixing edge with fixing holes and an oil drain hole. The fixing holes are used to screw the inner liner onto the profile below the inner wall. V-shaped partitions are provided on the outer wall of the inner liner (see appendix for details). Figure 3The upper inner part of the inner liner contains the volute centrifuge 11, and the lower inner part contains the sound-absorbing mesh 10. There is a few centimeters of space between each sound-absorbing mesh 10. The sound-absorbing mesh 10 is composed of multiple meshes (changes in the kitchen ceiling height will cause the range hood decorative hood, inner wall, and inner liner to rise, and the rising of the inner liner will provide more space to increase the number of sound-absorbing meshes 10 according to the actual situation). Each of the multiple sound-absorbing meshes 10 has an L-shaped profile at its left and right ends. The sound-absorbing meshes 10 are fixed to the L-shaped profiles with screws. The installation method of the L-shaped profiles is the same as that of the inner liner. Therefore, the inner liner, the sound-absorbing meshes 10, and the L-shaped profiles can all be quickly disassembled and cleaned. The lower part of the range hood has a fume hood, and the control panel is located directly in front of the fume hood. The front of the control panel (range hood control panel)... The area around the range hood (including the panel) where the human head is most likely to collide with the range hood is designed and equipped with a collision-resistant component that matches the area where the human head is most likely to collide with the range hood. The collision-resistant component has a hollow section in the middle to facilitate the operation of the control panel buttons. The air inlet of the range hood has three backward-sloping oil fume filters. Below the filters is an oil fume collection groove, which is sloping from left to right or right to left (referred to as the sloping groove). The lowest point of the sloping groove is located on the inner side of the smoke collection plate 8. At the lowest point, there is an oil collection hole. Below the oil collection hole is an oil bottle. The lower inner part of the oil collection hole has an internal thread interface that matches the oil bottle. At the center of the internal thread interface is a downward-hanging oil guide nozzle. The distance between the oil collection hole and the smoke collection plate 8 is >50. The smoke collection plates 8 are located at both ends of the hood. The installation method is a longitudinal installation where the T-shaped head of the smoke collection plate 8 is inserted upwards and then pushed backwards. The upper outer side of the smoke collection plate 8 is the range hood's air outlet. A pipe on the back of each air outlet connects to the main air supply pipe. Below the range hood body is the gas stove, a combination of two burners and one induction cooker. The two burners are side-by-side, with the induction cooker positioned to the left of the burners. The different configuration and arrangement of the burners and induction cooker in this invention results in an overall gas stove length > 800mm, thus causing the range hood length > 900mm. Existing gas stoves generally have an overall length ≤ 800mm, and existing range hoods generally have a length ≤ 900mm. Existing range hood lengths... After covering the gas stove (taking a gas stove length of 700mm as an example), the distance on the left and right is only about 100mm. In addition, if you put the swivel on the burner, the top edge of the pot may be flush with the vertical lines of both ends of the range hood. The existing gas stoves are mainly two-burner, and no matter which burner you use, the range hood's suction power will be helpless against the large amount of oil fumes that burst out in an instant. This is also a major problem that causes oil fumes to escape to the left and right when cooking in the kitchen. The control panel 9 is located at the bottom front of the gas stove. The control panel 9 is located between the top edge of the base cabinet door and the countertop. On the left side of the control panel 9 (four dots) is the microwave oven touch control key. The microwave oven control key is arranged to the right in the following order: vent - burner control key - vent - burner control key.
[0027] Example 2, as shown in the attached document Figure 2 The side view of the range hood is shown. The side view of the range hood includes the finishing piece 18 at the upper rear corner of the decorative cover. The finishing piece 10 is a soft plastic part. The rear upright edge of the decorative cover and the edge of the range hood that contacts the wall are provided with a 3mm wide soft shock-absorbing strip. Below the finishing piece 10 is the parallel hanger 19. Below the parallel hanger 19 is a 30mm gap reserved between the inner rear wall of the range hood and the wall. This space is for the range hood's air supply pipe to pass through. Below and in front of this space is the honeycomb structure 30. The main function of the honeycomb structure 30 is to support the upper and lower parts and ensure the load-bearing frame of the range hood after its length increases.
[0028] Example 3, as shown in the appendix Figure 3 The elevation view of the inner liner's outer wall is shown. The inner liner's outer wall includes holes and spacers 20. The spacers 20 are two spacers of different lengths combined to form a V shape. There is a gap at the bottom of the V shape (as shown in the figure) to allow oil stains hanging on the wall to flow downwards. The first set of spacers at the top has the left spacer shorter than the right spacer, and the second set has the left spacer longer than the right spacer. This sequence forms a stepped, multi-cavity, and interconnected through-layered cavity between the inner wall and the inner liner.
[0029] Example 4, as shown in the appendix Figure 4 The bottom view shows the small and large top suction cups above appliances such as the sink and rice cooker. The bottom view includes the pre-embedded hole 23 for the mechanical installation of the shelf. The depth of the pre-embedded hole 23 is 30mm, the width is 1.5 times that of the T-shaped head, and 0.5 times the length of the pre-embedded hole. The deepest part has a male and female groove that matches the T-shaped head. The mechanical installation method of the shelf is to insert the T-shaped head of the shelf into the pre-embedded hole 23 and push it to the left. The T-shaped head will then be locked in the male and female groove. Above the pre-embedded hole 23 is the air intake mesh of the large top suction cup. The air intake mesh is installed by snap-on. The air intake mesh has an air intake hole 21. Above the air intake mesh is the lighting 22. The lighting 22 and the left and right ends of the large top suction cup are provided with screw holes for fixing to the bottom plate of the wall cabinet.
[0030] Example 5, as shown in the appendix Figure 5 The side view of the small and large ceiling-mounted range hoods above the sink and rice cooker is shown. The top of the side view shows interface 5, which is a circular interface with a diameter of 80mm. Below the interface is an exhaust pipe with a length of 300mm and a width of 20mm. Above the exhaust pipe is a wall mount 24 for fixing the exhaust pipe. A gap of about 30mm is reserved between the exhaust pipe and the kitchen wall to avoid the corner line of the kitchen ceiling. The exhaust pipe is connected to the range hood of the small or large ceiling-mounted range hood. The control panel 25 is located below the range hood. Behind the control panel 25 is a pre-embedded hole 23.
[0031] Example 6, as shown in the appendix Figure 6The elevation and side views of the shelf are shown; the left figure is the elevation view of shelf 7. There is a decorative cover next to the T-shaped head of the shelf. This decorative cover is used to prevent the shelf from falling back after it is installed and is stuck in the remaining gap of the pre-embedded hole. The right figure is the side view of the shelf. The front of the shelf is equipped with hooks and U-shaped baskets for placing items. At the top of the side view is the T-shaped head 26 of the shelf.
[0032] Example 7, as shown in the appendix Figure 7 The check valve is shown in a side cross-sectional view. The check valve is square, and the check valve motor 27 is located on the outer casing of the check valve. The half-tooth 29 of the check valve motor meshes with the half-tooth 29 on the drive shaft of the valve plate 28. The number of meshing teeth is just enough to support the full opening and full closing of the valve plate. The valve plate opens fully upwards. Existing range hood check valves and those installed on the main flue rely entirely on the airflow of the range hood to open, which obstructs the airflow. Furthermore, the existing maximum exhaust pipe diameter is 200mm, resulting in obstruction in the exhaust pipe and check valve regardless of the range hood's exhaust flow rate. The increased flow area of the check valve and exhaust pipe in this invention effectively improves these problems.
[0033] Example 8, as shown in the appendix Figure 8 The elevation and side views of the range hood parallel mounting bracket base are shown. The left image is the elevation view of the parallel mounting bracket. At each end of the parallel mounting bracket, there is an anti-slip hole 32 with a height of about 20mm. The perimeter of the hole is grooved for anti-slip treatment. During installation and fixing, the anti-slip pad located on the screw cap will effectively engage with the parallel mounting bracket. The opening height of the anti-slip hole 32 is 20mm, which also facilitates the slight up and down adjustment of the parallel mounting bracket. The right image is the side view of the parallel mounting bracket, which is equipped with a fixing screw 31.
[0034] The above description is merely a preferred embodiment of the present invention and does not limit the scope of the patent. Those skilled in the art should understand that any modifications and improvements made without departing from the inventive concept and design of the present invention are within the scope of protection of the present invention.
