Description

Technical Field

[0001] This utility model relates to the technical field of kitchen utensils, and more specifically, to a novel integrated kitchen stove and range hood system. Background Technology

[0002] A range hood is a household appliance used in the kitchen to remove fumes, steam, and odors generated during cooking. It is typically installed above the stove and uses a built-in fan system to draw in the fumes and exhaust them outdoors or into a shared flue. Current range hoods, which directly draw in fumes using a fan, cause the fumes to adhere to the fan and surrounding equipment, requiring frequent disassembly and cleaning, which is inconvenient for users. Existing cabinet-style range hoods enclose the stove within a cabinet to prevent fumes from spreading into the room. Furthermore, current range hoods often create a vacuum in the environment, which, in winter with closed windows, can cause odors to be drawn back from the sewers, failing to meet modern environmental needs. Additionally, current range hoods neglect the exhaust of combustion gases, resulting in insufficient negative pressure near the stove, leading to incomplete exhaust of combustion gases.

[0003] Chinese Patent Application Document 1 (Application No.: 2016211101890, Application Date: 2016.10.10) discloses a split-type range hood, including: a fan 101' and a cabinet 102'. The cabinet 102' is a cabinet-shaped enclosure with openings on the front and bottom sides. A mounting hole for the fan 101' is provided on the top of the cabinet 102'. The cabinet 102' is used to enclose the oil fumes generated by the stove within a cabinet cavity 122'. The fan 101' is fitted into the mounting hole on the top of the cabinet 102' and is used to draw the oil fumes from the cabinet cavity 122' and exhaust them outdoors. The cabinet 102' includes a top panel 123', a back panel 124', and two side panels 125'. The side panels 125' and the back panel 124' are connected by connectors to form the U-shaped main body of the cabinet 102'. Both the side panels 125' and the back panel 124' are hollow rectangular panels, which are composed of segmented hollow rectangular panels connected by connectors. The various cabinet panels of this split-type range hood need to be connected by connectors to form the cabinet. The connectors are difficult to process, the production process is more complicated than the original, and the weight is also higher. Furthermore, this split-type range hood is prone to creating negative pressure in the working space during use, making it easy for the environment to draw air from the sewer.

[0004] Chinese Patent Application Document 2 (Application No.: 2019216254881, Application Date: 2019.09.27) discloses a spray heat exchange type integrated fresh air and range hood, including a range hood body with a fresh air component integrated therein. The fresh air component includes a fresh air duct connected to the range hood body, and a filter component embedded along the duct. Fresh air introduced by a fan passes through the filter component and enters the room. A heat exchange section is formed inside the fresh air duct, which includes a water supply jacket and a water return jacket, and heat exchange is performed on the fresh air through spraying. This spray heat exchange type integrated fresh air and range hood seems to solve the air supply problem of Chinese Patent Document 1, but the air inlet and outlet are too close together, making it difficult to achieve both effective air supply and the formation of a strong negative pressure for smoke extraction above the stove. Furthermore, this spray heat exchange type integrated fresh air and range hood is an open exhaust system, which cannot meet the actual needs of Chinese kitchens for complete removal of strong oil fumes.

[0005] Chinese Patent Application Document 3 (Application No.: 2017101119543, Application Date: 2017.02.28) discloses a kitchen fume extraction cooking device, including: a range hood body and a stove, the stove having burners; the range hood body is located above the stove, the range hood body has an oil fume intake inlet and an oil fume exhaust outlet; an oil fume swirling device is installed between the range hood body and the stove, the oil fume swirling device has an air duct, the air duct has an air inlet and an air outlet, the oil fume swirling device uses the airflow ejected from the air outlet to form a tornado-like cyclone that swirls the oil fumes and guides the oil fumes to the oil fume intake inlet; the air intake of this kitchen fume extraction cooking device swirls from the periphery of the device, which cannot avoid creating a negative pressure situation in the surrounding environment of the device, and at the same time cannot meet the actual need of Chinese kitchens to completely remove strong oil fumes.

[0006] Therefore, a new type of integrated kitchen stove and range hood system that has air supply function to avoid creating negative pressure in the environment; and has strong negative pressure near the stove to meet the needs of Chinese-style strong oil fume absorption; and is suitable for both winter and summer seasons and Chinese kitchens is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0007] In view of this, the present invention provides a novel integrated kitchen stove range hood system to solve the problems of negative pressure caused by the range hood to the surrounding environment, resulting in backflow of odors from the sewer, incomplete extraction of fumes, and excessive heat in the kitchen during summer cooking.

[0008] This application provides a novel integrated kitchen stove and range hood system, including a cabinet, an exhaust fan, and a blower;

[0009] The cabinet includes a base plate, with a front baffle, left side panel, back panel, and right side panel vertically connected to its perimeter. A top panel is installed between the left side panel, back panel, and right side panel. The front baffle has a U-shaped structure with the opening facing the base plate. The base plate, top panel, left side panel, back panel, and right side panel are all rectangular. The front baffle and back panel are positioned opposite each other and parallel to each other. The left side panel and right side panel are positioned opposite each other and parallel to each other. The base plate and top panel are positioned opposite each other and parallel to each other. The left side panel, back panel, and right side panel form a U-shaped structure with the opening facing forward.

[0010] A front air vent is located on the side of the front baffle away from the back panel;

[0011] The top plate has mounting holes, which are rectangular holes that penetrate the top plate along its thickness. The exhaust fan is fixedly connected to the mounting holes. The top plate has upper fastening grooves on the periphery of the side closest to the bottom plate. The openings of the upper fastening grooves correspond to the tops of the left side plate, back plate, and right side plate, respectively. The tops of the left side plate, back plate, and right side plate are fastened into the upper fastening grooves.

[0012] The bottom plate has a stove hole and a lower air outlet on the side near the top plate. The stove hole and the lower air outlet penetrate the bottom plate along the thickness direction. The orthographic projection of the stove hole and the orthographic projection of the lower air outlet along the thickness direction of the bottom plate do not coincide. There are at least three lower air outlets, and at least three lower air outlets are arranged around the stove hole.

[0013] The bottom plate has a snap-fit ​​groove on the periphery of the side closest to the bottom plate. The opening of the snap-fit ​​groove corresponds to the bottom of the left side plate, the back plate and the right side plate respectively. The bottom of the left side plate, the back plate and the right side plate are snapped into the snap-fit ​​groove.

[0014] Both the front air outlet and the lower air outlet include a fixed retaining ring and an adjusting blade rotatably connected to the fixed retaining ring. The fixed retaining ring has a ring structure, and the adjusting blade has a circular structure. The adjusting blade is located inside the fixed retaining ring and rotates clockwise or counterclockwise inside the fixed retaining ring. The fixed retaining ring of the front air outlet is fixedly connected to the front baffle, and the fixed retaining ring of the lower air outlet is fixedly connected to the base plate.

[0015] The air supply unit includes an indoor air supply unit and an outdoor air supply unit. The indoor air supply unit is located on the right side panel away from the left side panel, and the outdoor air supply unit is located outdoors. The indoor air supply unit includes an expansion valve, an evaporator, a blower, and an indoor unit fan. The outdoor air supply unit includes an outdoor unit fan, a condenser, and a compressor.

[0016] The compressor, condenser, expansion valve, and evaporator are connected in sequence. A refrigerant delivery pipe connects the condenser and the evaporator. An expansion valve is installed on the refrigerant delivery pipe. The compressor, condenser, expansion valve, and evaporator form a closed loop. The outdoor unit fan and the indoor unit fan, as well as the indoor unit fan and the lower air outlet, are connected by a lower air outlet pipe. The evaporator is connected to the front air outlet through a front air outlet pipe.

[0017] Compared with the prior art, the novel integrated kitchen stove and range hood system provided by this utility model achieves at least the following beneficial effects:

[0018] First, the novel integrated kitchen stove and range hood system provided by this utility model can avoid creating negative pressure in the environment and solve the problem of kitchen sewer backflow odors. This utility model also prevents cold air from being drawn from the kitchen itself, which helps to balance the constant pressure within the kitchen. To extract the fumes drawn by the exhaust fan, fresh air is supplied from the outside via a blower. The exhaust fan and blower operate at approximately balanced power, completing the fume extraction function while simultaneously supplying fresh air, preventing negative pressure from forming in the external environment of the cabinet. This effectively solves the problem of odors backflow from the sewer due to negative pressure, especially in winter when kitchens experience negative pressure-induced odors.

[0019] Secondly, the novel integrated kitchen stove fume extraction cabinet system provided by this utility model can simultaneously create a strong negative pressure for fume extraction at the center of the stove burner holes, preventing the spread of fumes from the cabinet body through multiple means. Existing kitchen stove fume extraction cabinets only have an exhaust system, and the airflow gradually weakens from the exhaust fan to the vicinity of the stove, resulting in a relatively weak negative pressure. This utility model, on the one hand, sets up a down-draft air outlet on the stove to deliver fresh air, compensating for the weak airflow near the stove and effectively preventing the spread of fumes. On the other hand, this utility model has no less than three down-draft air outlets, forming a cylindrical air duct from the stove burner holes to the exhaust fan, completely sealing the fumes within the formed cylindrical air duct, further effectively preventing the fumes from spreading outward and solving the problems of fumes leakage and incomplete exhaust into the kitchen.

[0020] Third, the novel integrated kitchen stove and range hood system provided by this utility model is suitable for use in both winter and summer, increasing the comfort of Chinese kitchens. Traditional Chinese kitchens produce a lot of oil fumes from frying and cooking, which often leads to a sudden rise in kitchen temperature. The downdraft air duct designed in this utility model not only relatively seals the oil fumes within the air duct, but also seals and carries away most of the heat. Furthermore, this utility model can release cold air through the front air vent to cool the environment and improve comfort during cooking. At the same time, the universal air vent design of the front air vent allows users to manually adjust it so that the cold air blows towards them, meeting more flexible usage requirements and personalized needs.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all the technical effects described above at the same time.

[0055] Specifically, continue to refer to Figure 2 and Figure 3 As shown, the novel integrated kitchen stove and range hood system provided in this embodiment can be an improved integrated kitchen stove and range hood system. The cabinet 3 provided in this embodiment includes: a top panel 31, a bottom panel 32, a back panel 33, a left side panel 30, and a right side panel 34; the left side panel 30, the right side panel 34, and the back panel 33 are all rectangular panels with a thickness of no more than 10mm; the left side panel 30, the right side panel 34, and the back panel 33 are integrally formed, and the left side panel 30, the right side panel 34, and the back panel 33 are connected to form a U-shaped structure of the cabinet 3.

[0056] Preferably, in this embodiment, a cabinet 3 with a length of 900mm, a width of 420mm, and a height of 800mm is constructed using a rectangular aluminum plate with a length of 105mm and a height of 800mm. The integrated cabinet 3 can be mass-produced using molds, which improves the manufacturing efficiency of the cabinet 3, saves manual installation steps, and thus saves costs.

[0057] Continue to refer to Figure 2 As shown, the cabinet 3 also includes a front baffle 35, which has a U-shaped structure. The front baffle 35 is located at the top of the U-shaped opening of the U-shaped structure, and the opening of the U-shaped structure of the front baffle 35 faces the bottom plate. The front baffle 35 is used to block the oil fumes from the inside of the cabinet 3 near the stove hole 321, preventing the oil fumes from spreading from the cabinet 3 to the indoor space. It is beneficial to provide a certain physical barrier when the exhaust fan 1 cannot completely remove all the oil fumes in the cabinet 3 in time, so as to ensure that the oil fumes do not spread directly to the indoor space.

[0058] Continue to refer to Figure 4As shown, the top plate 31 provided in this embodiment includes: a mounting hole 311 for the exhaust fan 1 and an upper mounting groove 312. The mounting hole 311 is a through hole located on the top plate 31 for mounting the exhaust fan 1. The upper mounting groove 312 is located on the outer periphery of the top plate 31 away from the stove hole 321. The opening of the upper mounting groove 312 is perpendicular to the horizontal ground and faces downward, for fastening the top plate 31 to the upper side of the U-shaped structure of the cabinet 3.

[0059] Continue to refer to Figure 5 As shown, the base plate 32 provided in this embodiment includes: a gas stove hole 321 for gas stove installation, a lower air outlet 322, and a lower mounting groove 323; the base plate 32 has a gas stove hole 321 and a lower air outlet 322 on the side near the top plate 31. The gas stove hole 321 is a through hole located on the base plate 32, and at least one is provided for mounting the gas stove; the lower air outlets 322 are evenly distributed around the circumference of the gas stove hole 321, and at least three are provided around each gas stove hole 321. The lower air outlets 322 are connected to the blower 2 through the lower air duct 232 and deliver fresh air; a lower mounting groove 323 is provided on a portion of the periphery of the base plate 32 near the top plate 31. The lower mounting groove 323 is located on the inner periphery of the base plate 32 near the gas stove hole 321. The opening of the lower mounting groove 323 is perpendicular to the horizontal ground and faces upward, and is used to fasten the base plate 32 to the lower side of the U-shaped structure of the cabinet 3.

[0060] Preferably, when only one burner hole 321 is provided, the opening diameter of the burner hole 321 can be 290mm to adapt to the standard size of a general single-burner gas stove; when two burner holes 321 are provided, the opening diameter of the burner hole 321 can be 353mm to adapt to the standard size of a general double-burner gas stove.

[0061] The top plate 31 is fastened to the upper side of the U-shaped structure of the cabinet 3. The bottom periphery of the top plate 31 is provided with an upper fastening groove 312 for fixing the relative position of the cabinet 3 and the top plate 31 when fastened. The bottom plate 32 is fastened to the lower side of the U-shaped structure of the cabinet 3. The top periphery of the bottom plate 32 is provided with an upper fastening groove 312 U-shaped structure for fixing the relative position of the U-shaped structure and the bottom plate 32 when fastened. The top plate 31, the bottom plate 32 and the U-shaped structure are assembled together to form the cabinet 3 of the range hood.

[0062] The front baffle 35 is provided with a front air outlet 351: the front baffle 35 is provided with at least two front air outlets 351 along the height extension direction, the front air outlets 351 are connected to the blower 2 through the front air duct 235, and deliver cold air to the kitchen room.

[0063] Continue to refer to Figure 6As shown, both the front air outlet 351 and the lower air outlet 322 in this embodiment are provided with a circular universal air outlet, and the air outlet orientation of the universal air outlet is adjustable. Both the front air outlet 351 and the lower air outlet 322 include a fixing ring 37 and an adjusting blade 36 rotatably connected to the fixing ring 37. The outer diameter of the fixing ring 37 is between 62-76mm, which is used to fix the adjusting blade 36. The adjusting blade 36 can be flipped inside the fixing ring 37. By manually turning the adjusting blade 36, the size of the opening inside the fixing ring 37 can be controlled, thereby controlling the allowable air volume.

[0064] The air supply direction of the down-vent 322 can be directed towards the burner hole 321. By flipping the adjusting blade 36 on the down-vent 322, the fresh air supplied by the down-vent 322 is blown towards the burner hole 321 at a 45° angle. This creates a fresh air duct around the burner hole 321 that seals off the fumes, preventing negative pressure on the surrounding environment. The fresh air duct further prevents the fumes from spreading, enhances the negative air pressure near the burner, and compensates for the weak exhaust of the exhaust fan 1 near the burner on the top plate 31, increasing the exhaust velocity of the fumes towards the exhaust fan 1. When the cabinet 3 is not in use, flipping the adjusting blade 36 on the down-vent 322 to 0° closes the down-vent 322, preventing cold outdoor air from entering and avoiding a drop in indoor temperature during winter.

[0065] The adjustable blades 36 on the front air outlet 351 can be manually adjusted so that the air supply direction of the front air outlet 351 is towards the user, which can reduce the ambient temperature around the user in the high temperature environment of the kitchen and solve the problem of heat during the cooking process in Chinese kitchens.

[0066] Continue to refer to Figure 2 and Figure 7 As shown, Figure 7This is a flowchart of the refrigeration and air supply system provided by this utility model; the air supply fan 2 includes: an indoor air supply unit 21 and an outdoor air supply unit 22. The indoor air supply unit 21 is located on the outside of the left side panel 30 or the right side panel 34 away from the burner hole 321; the indoor air supply unit 21 is connected to the lower air outlet 322 through the lower air supply duct 232, and connected to the front air outlet 351 through the front air supply duct 235; the indoor air supply unit 21 includes: an expansion valve 211, an evaporator 212, a blower 213, and an indoor unit fan 214. The outdoor air supply unit 22 is located outdoors and includes an outdoor unit fan 221, a condenser 222, and a compressor 223. The system comprises an expansion valve 211, an evaporator 212, a condenser 222, and a compressor 223, forming a refrigerant circulation system. The compressor 223, condenser 222, expansion valve 211, and evaporator 212 are connected sequentially via a refrigerant delivery pipe (not shown in the figure), which contains refrigerant. In this refrigerant circulation system, the compressor 223 is responsible for compressing the gaseous refrigerant, the condenser 222 condenses the high-temperature and high-pressure refrigerant into a liquid, the expansion valve 211 increases the volume of the liquid refrigerant and decreases its pressure and temperature, and the evaporator 212 evaporates the liquid refrigerant into a gas to absorb heat, thereby achieving a cooling effect.

[0067] Furthermore, the blower 213, the outdoor unit fan 221, and the aforementioned refrigerant circulation system constitute a refrigeration system. The blower 213 inputs hot air from the kitchen into the evaporator 212, where the hot air exchanges heat with the evaporator 212, and the resulting cold air is returned to the kitchen via the front air outlet 351 through the front air duct 235; this cools the user's kitchen environment and reduces the humidity and heat in the kitchen during summer and autumn. The outdoor unit fan 221 draws in ambient outdoor air, which exchanges heat with the condenser 222, causing the ambient outdoor air to warm up and become hot outdoor air; on the one hand, this hot outdoor air... The hot air can be directly discharged outside the outdoor unit fan 221. On the other hand, the outdoor hot air can be sent into the indoor unit 21 through a section of the lower air supply duct 232. The indoor unit fan 214 in the indoor unit 21 further accelerates the hot air. The hot air can flow out from the lower air outlet 322 through the other section of the lower air supply duct 232 to further increase the central thermal temperature of the burner hole 321 and improve the heating efficiency during cooking. Furthermore, the hot air provides oxygen supply for the combustion of the burner hole 321, which can increase the gas combustion efficiency at the burner hole 321.

[0068] Optionally, when the diameter of the down-flow duct 232 is greater than 9cm and the diameter of the down-flow outlet 322 is greater than 7cm, the outdoor air intake volume is enhanced by using large duct diameter and large outlet diameter, so that the outdoor unit fan 221 and indoor unit fan 214 do not need to be turned on in low winter conditions; adopting this large duct diameter and large outlet diameter scheme can save energy.

[0069] In practical use, this embodiment is applicable to kitchen use in spring and summer. In the hot summer, the exhaust fan 1 and the blower 2 can be turned on at the same time. The adjusting blades 36 on the front air outlet 351 are adjusted to face the user, so that the cold air generated by the blower indoor unit 21, including the expansion valve 211, evaporator 212, blower 213 and indoor fan 214, blows the user and reduces the ambient temperature of the user's surroundings during cooking. At the same time, the adjusting blades 36 of the lower air outlet 322 are directed towards the stove hole 321, forming a duct that compresses the oil fumes and sends the oil fumes into the exhaust fan 1. In the cold winter temperature, the refrigeration system and the lower air outlet 322 are closed. The blower indoor unit 21 directly draws outdoor ambient temperature air from the outside. The outdoor fan 221 and the indoor fan 214 work together to blow air and increase the airflow speed of the lower air outlet 322, forming a duct that compresses the oil fumes and sends the oil fumes into the exhaust fan 1.

[0070] As can be seen from the above embodiments, the novel integrated kitchen stove and range hood system provided in this embodiment achieves at least the following beneficial effects:

[0071] First, the novel integrated kitchen stove and range hood system provided in this embodiment can avoid creating negative pressure in the environment and solve the problem of kitchen sewer backflow odor. This embodiment avoids the cold air outside the cabinet 3 being drawn from the kitchen itself, which is conducive to balancing the constant pressure in the kitchen. In order to extract the gas drawn by the exhaust fan 1, fresh air is drawn from the outside through the supply fan 2. The operating power of the exhaust fan 1 and the supply fan 2 is approximately balanced, which completes the function of extracting oil fumes while timely replenishing fresh air, avoiding the formation of negative pressure in the external environment of the cabinet, and can effectively solve the problem of odor backflow from the sewer due to negative pressure, especially the problem of odor backflow in the kitchen due to negative pressure in winter. Secondly, the novel integrated kitchen stove fume extraction cabinet system provided in this embodiment can simultaneously create a strong negative pressure for fume extraction at the center of the burner hole 321, preventing the spread of fumes from the cabinet 3 through multiple means. Existing kitchen stove fume extraction cabinets only have an exhaust system, and the airflow gradually weakens from the exhaust fan to the vicinity of the stove, resulting in a weaker negative pressure. This embodiment addresses this by installing a downdraft vent 322 on the stove to deliver fresh air, compensating for the weak airflow near the stove and effectively preventing the spread of fumes. Furthermore, this embodiment features at least three downdraft vents 322, forming a cylindrical air duct from the burner hole 321 where fumes are generated to the exhaust fan 1, completely sealing the fumes within the cylindrical air duct and further effectively preventing the fumes from spreading outward, thus solving the problems of fumes leakage and incomplete exhaust into the kitchen.

[0072] Third, the novel integrated kitchen stove and range hood system provided in this embodiment is suitable for use in both winter and summer, increasing the comfort of Chinese kitchens. Traditional Chinese kitchens produce a lot of oil fumes from frying and cooking, which often leads to a sudden rise in kitchen temperature. The downward air supply duct 232 designed in this utility model forms an air duct that not only relatively seals the oil fumes within the air duct, but also seals and carries away most of the heat. Furthermore, this embodiment can also release cold air through the front air supply vent 351 to cool the environment and improve comfort during cooking. At the same time, according to the omnidirectional air outlet design of the front air supply vent 351, the user can manually adjust it so that the cold air blows towards the user, meeting more flexible usage requirements and personalized needs.
