Description

Technical Field

[0001] The present invention belongs to the technical field of integrated stove air ducts, and in particular relates to a stabilizing device and method for an internal air duct of an integrated stove. Background Art

[0002] Integrated stoves, also known as environmentally friendly stoves or integrated environmentally friendly stoves in the industry, are kitchen appliances that integrate multiple functions such as range hoods, gas stoves, disinfection cabinets, and storage cabinets. They have the advantages of saving space, good fume extraction, energy saving, low consumption, and environmental protection. Integrated stoves use the principle of micro-aerodynamics, deep well down-discharge or side suction down-discharge, and the principle of down-discharge to produce a fluid negative pressure zone, so that the oil smoke can be sucked down like magic, and the phenomenon of oil smoke rising everywhere can no longer be seen. The oil smoke absorption rate is more than 95%. Integrated stoves are internationally leading kitchen appliances developed to solve the problem that traditional range hoods cannot completely eradicate oil smoke and improve the kitchen and home environment. This product organically combines range hoods, stoves, disinfection cabinets, storage cabinets, etc. to completely eradicate kitchen oil smoke.

[0003] At present, the installation of exhaust ducts in integrated stoves has not attracted much attention. An air inlet is set in the middle of the air duct, which is connected to the fan, and both ends of the air duct are air outlets. The air outlet at the appropriate end can be selected according to the installation requirements to connect with the exhaust port of the integrated stove. However, the existing air duct is not equipped with supporting and stabilizing components, which will cause serious oil accumulation and poor stability after the air duct is used for a long time. Moreover, even if some air ducts use supporting components, there are many hidden dangers due to poor fixing effect. Summary of the invention

[0004] The purpose of the present invention is to provide a technical solution of a stabilizing device and method for the internal air duct of an integrated stove in view of the deficiencies in the prior art.

The two ends of the air duct are supported and stabilized by a stabilizing end frame, and the tops of the two ends of the air duct are pressed and limited by a top pressure assembly, and the middle part of the air duct is auxiliary supported by a stabilizing support plate, thereby effectively ensuring the structural stability of the air duct and making the smoke in the air duct discharge smoother. In addition, due to the ingenious design of the stabilizing end frame structure during actual installation, only the adjustment plate needs to be moved to drive the side support plates on both sides to move synchronously, so that the side support plates on both sides can be adjusted according to the actual width of the air duct, and the structural balance of the stabilizing end frame itself can be maintained. At the same time, the installation position of the stabilizing end frames on both sides of the stabilizing support plate is controlled by a scale, so that the stabilizing device can be adjusted according to the actual length of the air duct, and the balance of the stabilizing device itself can be maintained, thereby ensuring the supporting and stabilizing effect of the air duct.

[0015] The method for installing the stabilizing device for the internal air duct of an integrated stove as described above is characterized in that it includes the following steps:

[0016] 1) Assembling the stable end frame:

[0017] (1) First, install the limit rod on the main support rod, match the limit rod with the threaded through hole on the main support rod, pass the limit rod through the threaded through hole, and continue to move the limit rod until the external thread section at the center of the limit rod moves to the threaded through hole, and rotate the limit rod so that the external thread section is completely screwed into the threaded through hole; through the cooperation between the external thread section and the threaded through hole, the precise installation between the limit rod and the main support rod is achieved, and because the external thread section is located at the center of the limit rod, when the limit rod is threadedly connected to the main support rod, it can ensure that the length of the limit rod extending from the two ends of the threaded through hole is equal, thereby ensuring the overall structural balance and stability of the stable end frame, which is more conducive to the stable support of the end of the air duct by the stable end frame;

[0018] (2) Install side support plates on both sides of the main support rod, match the through holes on the side support plates with the limit rods, move the side support plates so that the side support plates are sleeved on the limit rods, and ensure that the side clamping plates on the side support plates on both sides of the main support rods are arranged oppositely, and then insert the limit rings at both ends of the limit rods; the side support plates are accurately sleeved and positioned through the through holes and the limit rods, which effectively reduces the actual installation difficulty and is also conducive to the subsequent connection between the adjustment plate and the side support plates;

[0019] (3) Place the adjusting plate on the main support rod so that the card slot on the bottom surface of the adjusting plate is just inserted into the protrusion on the top surface of the main support rod, and then install the adjusting plate and the side support plate. First, connect the side support plate on one side with the adjusting plate through the connecting rod, and then adjust the front and rear position of the side support plate on the other side along the limit rod, and then connect the adjusting plate on the other side with the side support plate through the connecting rod, and then adjust the position of the adjusting plate, move the adjusting plate in the opposite direction of the stable support plate, until the adjusting plate moves to the limit position, and tighten the first fixing screw; the precise card connection and limit between the adjusting plate and the main support rod are achieved through the card slot and the protrusion, and the installation is convenient and simple. Connection holes are reserved in advance on the adjusting plate and the side support plate. First, flexibly connect the side support plate on one side with the adjusting plate through the connecting rod, and then adjust the side support plate on the other side along the limit rod. The connecting rod can flexibly connect the side support plate on the other side with the adjustment plate. Since the position of the reserved connection hole is constant, the length of the connecting rod is constant, and the side support plates are limited by the limit rod, it can be ensured that the two side support plates are symmetrically distributed about the adjustment plate after installation, and the side clamping plates on the two side support plates are symmetrically arranged about the center of the adjustment plate, so as to ensure the structural balance of the stable end frame, so that the force on the end of the air duct is more balanced, and the whole of the air duct is more stable and firm, and it is ensured that the adjustment plate reaches the farthest length away from the stable support plate after the initial installation, so that the spacing between the side clamping plates on the two side support plates on the stable end frame in the initial state is the maximum value within the adjustable range, so as to facilitate the placement of the end of the air duct on the stable end frame, and also facilitate the subsequent further adjustment of the size of the stable end frame;

[0020] 2) Installation of the stable end frame and the stable support plate: Install the stable end frame at both ends of the stable support plate, match the dovetail plug block with the dovetail slot on the bottom surface of the stable support plate, move the stable end frame so that the dovetail plug block is inserted into the dovetail slot, and tighten the third set screw; the dovetail plug block and the dovetail slot are used to achieve precise plug-in limit between the stable end frame and the stable support plate, and the third set screw is used to ensure the firm connection between the stable end frame and the stable support plate, thereby ensuring the structural stability of the entire stable device. This installation method is simple, does not require any size measurement, and can facilitate subsequent further adjustment of the position of the stable end frame;

[0021] 3) Installation of air duct and stabilizing device:

[0022] (1) Place the air duct horizontally on the stable support plate, adjust the left and right position of the air duct on the stable support plate so that the air inlet of the air duct is located at the center of the stable support plate, then adjust the stable end brackets at both ends of the stable support plate, loosen the third set screw, adjust the length of the dovetail plug inserted in the dovetail slot, and keep the length of the dovetail plugs at both ends inserted into the dovetail slots the same through the scale on the dovetail plug, until the stable end bracket moves to the end of the air duct and both ends of the air duct extend out of the stable end bracket at the corresponding end, and tighten the third set screw. The stable support plate supports and lifts the center position of the air duct to ensure that the air inlet is located at the center of the stable support plate, reducing the fluctuation effect on the air duct caused by the smoke entering the air inlet, and the air inlet is located in the middle of the air duct, thereby ensuring that the length of the stable support plate extending from both ends of the air duct is relatively balanced. Then, the installation position of the stable end brackets at both ends is controlled by the scale to ensure that the stable end brackets are symmetrically distributed at both ends of the support bracket. The stable end brackets further support and fix the air outlets at both ends of the air duct, thereby ensuring the overall stability and force balance of the air duct;

[0023] (2) Loosen the first set screw and move the adjustment plate toward the direction of the stabilizing support plate. The adjustment plate drives the side support plates on both sides to move toward the side of the air duct synchronously through the connecting rod. When the side clamping plate on one side of the side support plate touches one side of the air duct, the adjustment plate continues to move, and the side support plate touching the side of the air duct drives the synchronous movement of the air duct until the other side of the air duct contacts the side clamping plate on the other side of the side support plate. Tighten the first set screw; moving the adjustment plate can drive the side support plates on both sides to move toward the direction of the air duct at the same time, and because the side support plates are always symmetrically arranged on both sides of the adjustment plate, when the side support plates During the movement, the front and rear positions of the air duct on the stabilizing device can be further corrected and adjusted. When the side clamps on the side support plates on both sides are pressed against the two sides of the air duct, the side support plates move into place, and the ends of the air duct are supported and stabilized by the cooperation of the side support plates and the adjustment plates, while the side clamps on the side support plates clamp and limit the ends of the air duct, effectively preventing the shaking and deformation of the air duct, and the width center of the air duct is exactly located at the width center of the adjustment plate, and the width center of the adjustment plate is aligned with the width center of the stabilizing support plate, thereby ensuring the support stability and force balance of the air duct on the stabilizing device;

[0024] The cam is then moved back and forth between the two sides of the base plate, and the two ends of the base plate are fixed together by the U-shaped groove, so that the two ends of the base plate extend out of the side plates. Then, the top pressure plate is installed on the base plate, and the top pressure plate is connected to the base plate section between the two side plates through the U-shaped groove, and then the top pressure plate and the base plate are fixed by screws. Then, the limit members are installed at the two ends extending from the base plate, and the limit shaft is connected to the movable through-groove of the base plate, and the end of the limit shaft extends out of the movable through-groove. The limit shaft is moved along the movable through-groove until the limit plate contacts the side plate, and the fastening nut is selected at the end of the limit shaft and the fastening nut is tightened. Then, the base plate is moved downward along the adjusting groove until the top pressure plate contacts the top surface of the air duct, and the second fixing screw is tightened. The overall installation and disassembly are convenient and simple, and the base plate and the front and rear side plates are connected by adjusting the groove. The initial clamping limit between the plates, and ensuring that both ends of the base support plate extend out of the side clamping plates, can ensure the compression effect of the top pressure assembly on the top of the air duct, and limit the two ends of the base support plate by the limiter, effectively preventing the end of the base support plate from detaching from the side clamping plates, thereby improving the structural safety performance, and the top pressure plate realizes the clamping limit between the base support plate through the U-shaped groove, and after the top pressure plate is clamped, the bottom surface of the top pressure plate is not higher than the bottom surface height of the base support plate, thereby ensuring that the top pressure plate is always in contact with the top surface of the air duct, ensuring the compression and limiting effect of the top pressure plate on the top surface of the air duct, and the top pressure plate and the base support plate are further fixed by screws, effectively connecting the top pressure plate and the base support plate firmly, thereby ensuring the overall structural stability of the top pressure assembly, when the top pressure plate is pressed against the top surface of the air duct, the base support plate is indirectly limited and fixed by tightening the second fixing screw, thereby limiting and fixing the top pressure plate, ensuring the compression effect of the top pressure plate on the air duct;

[0025] 4) Installation of the air duct and the integrated stove: Place the assembled combination of the air duct and the stabilizing device into the installation cavity reserved in the integrated stove, and then use the mounting screws matching the positioning holes to fix the support rod to the inner wall of the integrated stove; assemble the air duct and the stabilizing device into one, and then fix the air duct to the integrated stove through the stabilizing device, effectively ensuring the structural firmness of the air duct, reducing the shaking and mechanical noise of the air duct during use, making the smoke discharge in the air duct smoother, and effectively extending the service life of the air duct.

[0026] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0027] The overall structural design of the present invention is ingenious and reasonable. Through the multiple designs of the stabilizing end frame, the top pressure component and the stabilizing support plate, the air duct is supported and stabilized at the same time, and the supporting firmness of the air duct is limitedly guaranteed, making the structure of the air duct more stable, effectively preventing the shaking and deformation of the air duct, reducing the mechanical noise during the use of the air duct, and improving the structural safety performance of the air duct. The stabilizing end frame and the stabilizing support plate are adjustably connected, so that the position of the stabilizing end frame can be adjusted according to the actual length of the air duct to ensure the supporting and clamping effect of the stabilizing end frame on the end of the air duct, while avoiding the air inlet position in the middle of the air duct, and the scale design on the dovetail plug block can be used to adjust the installation position of the stabilizing end frames on both sides of the stabilizing support plate to ensure that the stabilizing end frames on both sides are symmetrically arranged on the left and right sides of the stabilizing support plate, thereby improving the structural balance of the entire stabilizing device, and the present invention also improves the structure of the stabilizing end frame itself. The design ensures the basic structure of the stable end frame through the main support rod, realizes the connection and fixation between the stable end frame and the stable support plate, and at the same time the adjusting plate is movably hinged with the side support plates on both sides through the connecting rod. Therefore, by adjusting the left and right position of the adjusting plate on the main support rod, the spacing between the side support plates on both sides of the adjusting plate can be synchronously adjusted, so that the stable end frame can be suitable for supporting and clamping air ducts of different widths, and because the side support plates themselves are limited by the limit rods, the side support plates can only slide back and forth along the limit rods, thereby effectively ensuring the stability of the front and rear position adjustment of the side support plates, and the design of the top pressure component can compress and limit the air duct from the top of the air duct, further improving the overall stability of the air duct, and the top pressure component and the side support plates also adopt an adjustable connection, so that the top pressure component can be adjusted according to the height of the air duct, which is suitable for compressing and limiting air ducts of different heights.

[0028] The overall installation and disassembly of the present invention is convenient and simple, which is convenient for actual assembly operations. In the actual installation process, due to the ingenious design of the stable end frame structure, the stable end frame can be adjusted in size according to the actual width of the air duct, so as to realize the clamping and limiting of air ducts of different widths. When the size of the stable end frame is adjusted, the side support plates on both sides can be driven to move synchronously by moving the adjustment plate, and the front and rear positions of the air duct on the adjustment plate can be corrected and adjusted during the synchronous movement of the side support plates, so that when the side clamping plates on the side support plates on both sides collide with the front and rear end surfaces of the air duct, the width center of the air duct is also exactly located at the position of the adjustment plate. At the center position of the width, the side clamps are also symmetrically arranged on both sides of the adjustment plate, so as to ensure the stability of the support of the air duct end by the stable end frame and the structural balance of the stable end frame itself. At the same time, the installation position between the stable end frame and the stable support plate is adjustable, so that the stabilizing device can be adjusted according to the actual length of the air duct to ensure the stabilizing effect of the support on the end of the air duct, and the installation position of the stable end frames on both sides of the stable support plate can be controlled by the scale to ensure that the stable end frames are symmetrically arranged on both sides of the stable support plate, thereby ensuring the overall balance of the stabilizing device itself and thus ensuring the stabilizing effect of the support on the air duct.
