Description

Technical Field

[0001] The present invention relates to the technical field of kitchen equipment, and in particular to a multifunctional integrated stove. Background Art

[0002] An integrated stove is a device that integrates the functions of multiple kitchen appliances, mainly including functional modules such as gas stoves, range hoods and disinfection cabinets. It is usually installed in the kitchen for cooking, smoke exhaust and storing tableware.

[0003] In the air collecting box of the integrated stove, the air collecting box includes a box body and a fan arranged in the box body. Usually, two smoke exhaust ports are arranged on both sides of the box body. The air outlet of the fan is connected to one of the smoke exhaust ports by installing the fan in the forward and reverse directions (for example, the utility model patent applied for by the applicant with application number CN202220934706.5 "An integrated stove bellows assembly for preventing oil leakage"), thereby changing the exhaust direction to suit different installation environments.

[0004] In the utility model patent "An integrated stove bellows assembly for preventing oil seepage" with application number CN202220934706.5, although the fan can take in air from both ends when installed forward or reversely, one of the directions is from the motor side, and the resistance encountered when taking in air is large, resulting in the problem of large wind resistance. Summary of the Invention

[0005] The purpose of the present invention is to provide a multifunctional integrated stove, which has the function of conveniently changing the direction of smoke exhaust and reducing the wind resistance of smoke exhaust.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a multifunctional integrated stove, comprising an integrated stove body with an air collecting box, the air collecting box comprising a box body, a fan arranged in the box body, a partition arranged at the bottom of the box body to divide the space in the box body into an installation cavity and a smoke exhaust channel, the partition comprising an inclined section at one end connected to the left side of the box body and the other end extending obliquely downward, a horizontal section connected to the inclined section and the right side of the box body, the inclined section is provided with an air outlet connecting the installation cavity and the smoke exhaust channel and the air outlet end of the fan is installed in alignment, the box body is respectively provided with smoke exhaust ports on both sides of the smoke exhaust channel; a wind guide assembly is slidably connected in the smoke exhaust channel to connect the air outlet with any one of the smoke exhaust ports, the wind guide assembly comprises a telescopic tube telescopically arranged in the smoke exhaust channel and having a connecting port on the top, a telescopic tube arranged on the left side of the telescopic tube and having an arc-shaped concave on the top The cam is hinged on the top of the second curved deflector plate and is fixed on the bottom of the left side of the air outlet, so that the cam can be fixed on the bottom of the left side of the air outlet. When the cam is in the closed position, the cam can be fixed on the bottom of the left side of the air outlet. When the cam is in the closed position, the cam can be fixed on the bottom of the left side of the air outlet. When the cam is in the closed position, the cam can be fixed on the bottom of the left side of the air outlet. When the cam is in the closed position, the cam can be fixed on the bottom of the left side of the air outlet. When the cam is in the closed position, the cam can be fixed on the bottom of the left side of the air outlet. When the cam is in the closed position, the cam can be fixed on the bottom of the left side of the air outlet. When the cam is in the closed position, the cam can be fixed on the bottom of the left side of the air outlet. When the cam is in the closed position, the cam can be fixed on the bottom of the left side of the air outlet.

[0007] By adopting the above technical solution, when the surfaces of the arc hinged plate and the first arc guide plate are connected to the right side of the air outlet, the air outlet is communicated with the smoke exhaust port on the left, the communication port is located below the horizontal section, and the first arc guide plate can reduce wind resistance; when the telescopic tube moves toward the left and the surface of the second arc guide plate is connected to the left side of the air outlet, the communication port is located below the air outlet, and the arc hinged plate is rotated upward and connected to the lower left side of the air outlet to cover the gap between the telescopic tube and the inclined section, and the air outlet is communicated with the smoke exhaust port on the right, and the second arc guide plate can reduce wind resistance; at the same time, the air outlet is arranged on the inclined section, When the air outlet is connected to the smoke exhaust port on the left, the air outlet of the fan is tilted to reduce wind resistance; when the air outlet is connected to the smoke exhaust port on the right, the length of the turning path of the wind on the arc hinged plate and the second arc guide plate can be increased, which can reduce wind resistance. Therefore, the setting of the inclined section is also particularly important in this application. In this application, due to the setting of the inclined section, it is necessary to cooperate with the setting of the arc hinged plate to cover the gap between the telescopic tube and the inclined section. The arc hinged plate is rotated upward and fixed to the left bottom of the air outlet, which can be operated from the left smoke exhaust port. The telescopic tube is locked by a locking structure and can be operated from the installation cavity, which is convenient for operation.

[0008] The present invention is further configured as follows: two through holes are provided on the horizontal section, a threaded hole is provided on the upper surface of the telescopic tube which can be aligned with any one of the through holes during movement, and the locking structure includes a locking knob bolt that passes through one through hole and is threadedly connected to the threaded hole; when the air outlet is connected to the smoke exhaust port on the left, the telescopic tube moves to the right to an extreme state, and the threaded hole is aligned with one of the through holes; when the air outlet is connected to the smoke exhaust port on the right, the telescopic tube moves to the left to an extreme state, and the threaded hole is aligned with the other through hole.

[0009] By adopting the above technical solution, when the telescopic tube moves to the left and right moving states, it can be communicated with the smoke exhaust port on the right and left sides respectively, and can be fixed by tightening the knob bolt.

[0010] The present invention is further configured as follows: a linkage structure is provided between the arc hinge plate and the inclined section, which drives the arc hinge plate to rotate upward during the downward and leftward movement of the telescopic tube. The linkage structure includes two first pull rings arranged on the lower surface of the lower end of the inclined section and located on both sides of the air outlet, two second pull rings arranged on both sides of the lower end of the arc hinge plate, two cables respectively arranged between the first pull rings and the second pull rings, and a guide ring arranged in the middle of the inclined section for the cable to pass through. When the telescopic tube moves to the left to the extreme state, the cable straightens and drives the arc hinge plate to rotate upward and then contacts the left bottom of the air outlet to cover the gap between the telescopic tube and the inclined section.

[0011] By adopting the above technical solution, the linkage structure includes a first pull ring, a second pull ring and a cable. When the telescopic tube moves to the left to the extreme state, the cable drives the arc-shaped hinged plate to rotate upward and then abuts against the left bottom of the air outlet to cover the gap between the telescopic tube and the inclined section, thereby realizing linkage; at the same time, when the telescopic tube moves to the right to the extreme state, the arc-shaped hinged plate naturally rotates downward and resets under the action of gravity.

[0012] The present invention is further configured as follows: a socket extending in the horizontal direction is provided on the lower surface of the inclined section; a plug-in piece is provided at the lower end of the arc-shaped hinged plate, which can be in a horizontal state after being rotated upward and is inserted into the socket when the telescopic tube moves to the left; and a receiving groove is provided on the first arc-shaped guide plate corresponding to the plug-in piece.

[0013] By adopting the above technical solution, when the air outlet is connected to the smoke exhaust port on the right, the arc-shaped hinged plate is first rotated upward from the smoke exhaust port on the left to make the insert in a horizontal state. During the process of the telescopic tube moving downward to the left to the extreme state, the insert is inserted into the socket to achieve connection and fixation.

[0014] The present invention is further configured as follows: a fitting piece is provided at the lower end of the arc-shaped hinged plate for fitting onto the lower left surface of the air outlet after being rotated upward, and a fixing screw is provided between the fitting piece and the inclined section at an installation cavity for connecting the two.

[0015] By adopting the above technical solution, when the air outlet is connected to the smoke exhaust port on the right, the telescopic tube is first moved to the left to the extreme state, and then the arc-shaped hinge plate is rotated upward to connect the fitting piece with the inclined section, and then the two are connected through the fixing screws from the installation cavity, which facilitates operation.

[0016] The present invention is further configured as follows: a spherical limiting groove larger than the hemisphere is provided at the arc-shaped recess, a rubber spherical protrusion matching the spherical limiting groove is provided on the back of the arc-shaped hinge plate, and when the arc-shaped hinge plate is in the arc-shaped recess, the rubber spherical protrusion is embedded in the spherical limiting groove.

[0017] By adopting the above technical solution, by setting the spherical limit groove and the rubber spherical protrusion, the stability of the arc hinge plate installed in the arc depression can be further improved, avoiding large shaking during wind blowing, thereby reducing noise.

[0018] The present invention is further configured such that one end of the smoke exhaust passage close to the left side protrudes from the side surface of the box body.

[0019] By adopting the above technical solution, when the telescopic tube moves downward and to the left to its extreme state, the distance moved by the telescopic tube is the length of the positive projection range of the air outlet, and when the telescopic tube moves to the left to its extreme state, the first curved guide plate also needs to touch the left side of the smoke exhaust channel for limiting the position. At this time, the arc inclination angle left for the first curved guide plate cannot be too large, which will increase the wind resistance. By making the smoke exhaust channel close to the side of the square protruding box on the left, the arc inclination angle of the first curved guide plate can be increased to reduce the wind resistance.

[0020] The present invention is further configured such that: a first array of holes is provided on the first arc-shaped guide plate, and a second array of holes is provided on the second arc-shaped guide plate.

[0021] By adopting the above technical solution, the first holes and the second holes arranged in the array can absorb and dissipate sound waves through the principle of micropore noise reduction, thereby reducing the propagation of noise and having a noise reduction effect.

DETAILED DESCRIPTION

[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Example 1: A multifunctional integrated stove, such as Figure 1 and Figure 2 As shown, it includes an integrated stove body 1 with an air collection box 2, which includes a box body 3 and a fan 4 disposed within the box body 3. A partition 31 is provided at the bottom of the box body 3 to divide the space within the box body 3 into a mounting cavity 32 and a smoke exhaust channel 33. The partition 31 includes an inclined section 311 with one end connected to the left side of the box body 3 and the other end extending obliquely downward, and a horizontal section 312 connected to the inclined section 311 and on the right side of the box body 3. The inclined section 311 is provided with an air outlet 313 that connects the mounting cavity 32 and the smoke exhaust channel 33 and is aligned with the air outlet end of the fan 4. The box body 3 is provided with smoke exhaust ports 34 on both sides of the smoke exhaust channel 33.

[0035] like Figures 1 to 3As shown, one end of the smoke exhaust channel 33 near the left side protrudes from the side of the box body 3, and a wind guide assembly 5 is slidably connected in the smoke exhaust channel 33 to connect the air outlet 313 with any one of the smoke exhaust ports 34. The wind guide assembly 5 includes a telescopic tube 51 telescopically arranged in the smoke exhaust channel 33 and having a connecting port 511 at the top, a first arc-shaped guide plate 52 arranged on the left side of the telescopic tube 51 and having an arc-shaped recess 521 at the top, an arc-shaped hinged plate 53 with an upper end hingedly arranged on the top of the arc-shaped recess 521, a second arc-shaped guide plate 54 arranged in the telescopic tube 51, and a locking structure 55 arranged between the telescopic tube 51 and the horizontal section 312 and operable in the installation cavity 32. After rotating clockwise upward, the arc-shaped hinged plate 53 abuts against the left bottom side of the air outlet 313 to cover the gap between the telescopic tube 51 and the inclined section 311. The arc-shaped hinged plate 53 can be fixed when it abuts against the left bottom side of the air outlet 313. When the curved hinged plate 53 and the first curved deflector plate 52 are connected to the right side of the air outlet 313, the air outlet 313 communicates with the left smoke exhaust port 34, and the communication port 511 is located below the horizontal section 312. When the telescopic tube 51 moves leftward and the second curved deflector plate 54 is connected to the left side of the air outlet 313, the communication port 511 is located below the air outlet 313. The curved hinged plate 53 rotates upward and connects to the lower left side of the air outlet 313, communicating with the right smoke exhaust port 34. The first curved deflector plate 52 is provided with a first array of holes (not shown), and the second curved deflector plate 54 is provided with a second array of holes (not shown).

[0036] like Figures 2 to 6 As shown, two through holes 314 are provided on the horizontal section 312, and a threaded hole 512 is provided on the upper surface of the telescopic tube 51, which can be aligned with any one of the through holes 314 during the movement. The locking structure 55 includes a locking knob bolt 551 that passes through one through hole 314 and is threadedly connected to the threaded hole 512; when the air outlet 313 is connected to the smoke exhaust port 34 on the left, the telescopic tube 51 moves to the right to the extreme state, and the threaded hole 512 is aligned with one of the through holes 314; when the air outlet 313 is connected to the smoke exhaust port 34 on the right, the telescopic tube 51 moves to the left to the extreme state, and the threaded hole 512 is aligned with the other through hole 314.

[0037] like Figures 2 to 6As shown, a linkage structure 56 is provided between the arc-shaped hinge plate 53 and the inclined section 311 for driving the arc-shaped hinge plate 53 to rotate upward during the downward and leftward movement of the telescopic tube 51. The linkage structure 56 includes two first pull rings 561 provided on the lower surface of the lower end of the inclined section 311 and located on both sides of the air outlet 313, two second pull rings 562 provided on both sides of the lower end of the arc-shaped hinge plate 53, two cables 563 provided between the first pull rings 561 and the second pull rings 562 respectively, and a guide ring 564 provided in the middle of the inclined section 311 for the cables 563 to pass through. When the telescopic tube 51 moves to the left to the extreme state, the cable 563 is straightened and drives the arc-shaped hinge plate 53 to rotate upward and then abut against the left bottom of the air outlet 313 to cover the gap between the telescopic tube 51 and the inclined section 311.

[0038] like Figure 4 and Figure 6 As shown, a spherical limiting groove 523 larger than the hemisphere is provided at the arc-shaped recess 521, and a rubber spherical protrusion 58 matching the spherical limiting groove 523 is provided on the back of the arc-shaped hinge plate 53. When the arc-shaped hinge plate 53 is in the arc-shaped recess 521, the rubber spherical protrusion 58 is embedded in the spherical limiting groove 523.

[0039] Implementation effect: When the surfaces of the arc-shaped hinged plate 53 and the first arc-shaped guide plate 52 are connected to the right side of the air outlet 313, the air outlet 313 is communicated with the smoke exhaust port 34 on the left, and the connecting port 511 is located below the horizontal section 312. The first arc-shaped guide plate 52 can reduce wind resistance; when the telescopic tube 51 moves toward the left and makes the surface of the second arc-shaped guide plate 54 connected to the left side of the air outlet 313, the connecting port 511 is located below the air outlet 313, and the arc-shaped hinged plate 53 rotates upward and is connected to the lower left side of the air outlet 313 to cover the gap between the telescopic tube 51 and the inclined section 311. The air outlet 313 is communicated with the smoke exhaust port 34 on the right, and the second arc-shaped guide plate 54 can reduce wind resistance. At the same time, the air outlet 313 is arranged on the inclined section 311. When the air outlet 313 is connected to the smoke exhaust port 34 on the left, the air outlet 313 of the fan 4 is tilted, which can reduce wind resistance; when the air outlet 313 is connected to the smoke exhaust port 34 on the right, the turning path length of the wind on the arc-shaped hinged plate 53 and the second arc-shaped guide plate 54 can be increased, which can reduce wind resistance. Therefore, the setting of the inclined section 311 is also particularly important in this application. In this application, due to the setting of the inclined section 311, it is necessary to cooperate with the setting of the arc-shaped hinged plate 53 to cover the gap between the telescopic tube 51 and the inclined section 311. The arc-shaped hinged plate 53 is rotated upward and fixed to the left bottom of the air outlet 313, which can be operated from the left smoke exhaust port 34. The telescopic tube 51 is locked by the locking structure 55 and can be operated from the installation cavity 32, which is convenient for operation.

[0040] When the telescopic tube 51 moves to its left or right positions, it communicates with the right and left smoke outlets 34, respectively, and is secured by two locking knob bolts 551. The linkage structure 56 includes a first pull ring 561, a second pull ring 562, and a cable 563. When the telescopic tube 51 moves to the left to its limit position, the cable 563 drives the curved hinge plate 53 to rotate upward and then contact the left bottom of the air outlet 313, covering the gap between the telescopic tube 51 and the inclined section 311, thereby achieving linkage. Simultaneously, when the telescopic tube 51 moves to the right to its limit position, the curved hinge plate 53 naturally rotates downward under the action of gravity to reset. The provision of a spherical stopper 523 and a rubber spherical protrusion 58 further enhances the stability of the curved hinge plate 53 installed in the curved recess 521, preventing significant vibration when exposed to wind, thereby reducing noise. When the telescopic tube 51 moves downward and leftward to its limit position, the travel distance of the telescopic tube 51 is the length of the orthographic projection of the air outlet 313. Furthermore, when the telescopic tube 51 moves leftward to its limit position, the first curved guide plate 52 also needs to contact the left side of the smoke exhaust duct 33 to limit its position. At this time, the arc angle of the first curved guide plate 52 cannot be too large, as this will increase wind resistance. However, by positioning the smoke exhaust duct 33 closer to the side of the square protrusion of the box body 3 on the left, the arc angle of the first curved guide plate 52 can be increased, reducing wind resistance. The first and second holes arranged in the array absorb and dissipate sound waves through the principle of microporous noise reduction, thereby reducing noise propagation and achieving a noise reduction effect.

[0041] Example 2: A multifunctional integrated stove, such as Figure 7 and Figure 8 As shown, the difference from Example 1 is that the linkage structure 56 is not provided, and a sleeve 571 extending in the horizontal direction is provided on the lower surface of the inclined section 311, and the lower end of the arc-shaped hinged plate 53 is provided with an insert 572 which can be in a horizontal state after being rotated upward and is inserted into the sleeve 571 when the telescopic tube 51 moves to the left, and a receiving groove 522 is provided on the first arc-shaped guide plate 52 corresponding to the insert 572.

[0042] Implementation effect: When the air outlet 313 is connected to the smoke exhaust port 34 on the right, the arc-shaped hinge plate 53 is first rotated upward from the smoke exhaust port 34 on the left to make the insert 572 in a horizontal state. When the telescopic tube 51 moves downward to the left to the extreme state, the insert 572 is inserted into the socket 571 to achieve connection and fixation.

[0043] Example 3: A multifunctional integrated stove, such as Figure 9 and Figure 10As shown, the difference from Example 1 is that the linkage structure 56 is not provided, and a bonding piece 581 is provided at the lower end of the arc-shaped hinged plate 53, which is bonded to the lower left surface of the air outlet 313 after being rotated upward, and a fixing screw 582 is provided between the bonding piece 581 and the inclined section 311 at the installation cavity 32 to connect the two.

[0044] Implementation effect: When the air outlet 313 is connected to the smoke exhaust port 34 on the right, the telescopic tube 51 is first moved to the left to the extreme state, and then the arc-shaped hinge plate 53 is rotated upward to make the fitting piece 581 connected to the inclined section 311, and then the two are connected through the fixing screw 582 from the installation cavity 32, which is convenient for operation.

[0045] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
