Description

Technical Field

[0001] The present invention relates to the technical field of integrated stoves, and in particular to a reversible bellows structure and an integrated stove. Background Art

[0002] Integrated stoves usually include a fan and a bellows. The fan draws waste such as cooking fumes in the kitchen into the bellows and discharges them into the flue through the exhaust pipe. In order to make the bellows fit the different positions of the flue in the kitchen, many integrated stove bellows are currently equipped with two air outlets on the left and right. After the bellows inhale the cooking fumes, they are exhausted through the left or right air outlet. The air outlet direction can be selected conditionally according to actual needs during installation.

[0003] In order to realize the reversing function of the air outlet, there are usually two ways. One is to set air outlet ducts at both the left and right air outlets, and select the air outlet by setting a reversing device inside the bellows. In this way, the internal structure of the bellows is complicated, and there will be problems such as large air volume and air pressure loss and high noise. The production cost of setting up two air ducts is also high. Another way is to connect one air outlet to the air duct and block the other air outlet with a plugging cover. When reversing is required, the air duct and the plugging cover are removed and swapped. In this way, the air duct is inconvenient to install and disassemble.

[0004] Therefore, it is urgent to propose a reversible bellows structure and an integrated stove to solve the above problems. Summary of the invention

[0042] See also Figure 1 The present embodiment provides a reversible bellows structure, including a bellows body 100, two adapters 200, a blocking plate 300 and an air duct assembly 400. The bellows body 100 has a first air outlet 101 and a second air outlet 102. The two adapters 200 are respectively arranged at the first air outlet 101 and the second air outlet 102. The blocking plate 300 can be detachably connected to the adapter 200, and the blocking plate 300 is used to block the first air outlet 101 or the second air outlet 102. The air duct assembly 400 includes an air duct joint 410 and an air duct 420, and the air duct joint 410 is connected to the air duct 420, and the air duct joint 410 can be detachably connected to the adapter 200.

[0043] The bellows structure is connected to the blocking plate 300 and the air duct assembly 400 by providing an adapter 200 at both the first air outlet 101 and the second air outlet 102. Since the adapter 200, the blocking plate 300 and the air duct assembly 400 are all adaptable, when the air outlet needs to be switched, the blocking plate 300 and the air duct assembly 400 can be removed and swapped. The blocking plate 300 can prevent the loss of air volume and air pressure and save energy. The air duct 420 is connected to the adapter 200 through the air duct joint 410, and there is no need to disassemble the air duct 420 separately, so the assembly is very convenient and quick.

[0044] Continue to see Figure 1 The first air outlet 101 and the second air outlet 102 are respectively located on the left and right sides of the bellows body 100 and are arranged opposite to each other. The first air outlet 101 and the second air outlet 102 are both rectangular in shape. The first air outlet 101 and the second air outlet 102 are of the same shape, so that they can both be connected to the adapter 200.

[0045] Further, see Figure 1 and Figure 2 The bellows body 100 includes a box body 110 and an extension piece 120 . The extension piece 120 is connected to the first air outlet 101 . The adapter 200 located at one side of the first air outlet 101 is connected to the extension piece 120 .

[0046] The provision of the extension piece 120 facilitates the connection and disassembly of the adapter 200 and the housing 110, and avoids the first air outlet 101 being located too far inside and inconvenient to disassemble. In the present embodiment, the extension piece 120 is a rectangular frame structure, having a first port and a second port arranged relatively, and the first port is connected to the extension piece 120. Optionally, the adapter 200 and the extension piece 120 can be detachably connected by connecting pieces such as bolts. Optionally, to facilitate the connection between the adapter 200 and the extension piece 120, a first connecting flange can be provided on the edge of the first port of the adapter 200, and a mounting hole for passing the bolt can be provided on the first connecting flange.

[0047] Further, the second port is connected to the first air outlet 101, and optionally, can be connected to the box body 110 by welding. To facilitate welding of the extension piece 120 and the box body 110, a second connection flange can be provided at the second port.

[0048] For further information, see Figure 3 The adapter 200 includes a connection frame 210, the connection frame 210 is connected to the bellows body 100, a baffle 220 is provided on the connection frame 210, and there is a plug-in gap between the baffle 220 and the connection frame 210. The blocking plate 300 can be inserted into the plug-in gap along the first direction. The air duct joint 410 can be inserted into the plug-in gap along the first direction.

[0049] In this embodiment, the center of the connection frame 210 is set to a rectangular opening according to the shape of the first air outlet 101 (the second air outlet 102), and the outer edge is a rectangle. In this embodiment, the first direction is the length direction of the adapter 200, and the insertion direction of the blocking plate 300 is the length direction of the adapter 200. In other embodiments, the blocking plate 300 can also be inserted along the width direction of the adapter 200, which is not specifically limited here. The baffle 220 is set at the edge of the long side of the connection frame 210, and the size of the plug-in gap is to ensure that the blocking plate 300 can be inserted therein.

[0050] Further, multiple baffles 220 are disposed on opposite sides of the adapter 200, and the multiple baffles 220 on each side are disposed at intervals. In this embodiment, three baffles 220 are disposed on each long side of the connection frame 210, and the baffles 220 on both sides are symmetrically disposed.

[0051] Furthermore, a first assembly hole 221 is provided on the baffle 220, and a second assembly hole is provided on the connection frame 210. The first assembly hole 221 and the second assembly hole are used to pass a connecting piece, and the adapter 200 is connected to the bellows body 100 via the connecting piece.

[0052] It can be understood that the first assembly hole 221 on the baffle 220 and the second assembly hole on the connection frame 210 are arranged opposite to each other, so as to ensure that the connecting member can be inserted. Optionally, the connecting member can be a bolt, and accordingly, the bellows body 100 is also provided with a mounting hole for passing the bolt.

[0053] See also Figure 4 and Figure 5 The blocking plate 300 includes a blocking plate body 310, and a first avoidance opening 330 is provided at the edge of the blocking plate body 310. The first avoidance opening 330 forms a first flange 340 at the edge of the blocking plate body 310. The connecting piece can pass through the first assembly hole 221, the first avoidance opening 330 and the second assembly hole in sequence, and the connecting piece can support the first flange 340.

[0054] The two long side edges of the blocking plate body 310 are both provided with a first flange 340. The blocking plate body 310 in this embodiment is provided with three first flanges 340 at the edge of each long side, and the adjacent first flanges 340 are arranged at intervals, so that a long strip-shaped first avoidance opening 330 is formed between the adjacent first flanges 340. The position of the first avoidance opening 330 can be set according to the position of the first assembly hole 221 and the second assembly hole. In this embodiment, by setting the first avoidance opening 330 as a long strip-shaped opening, it is convenient to insert the bolts during the assembly process. In other embodiments, the first avoidance opening 330 can also be a through hole that can be inserted with bolts. After the assembly of the blocking plate 300 and the adapter 200 is completed, the bolts can support the first flange 340 to prevent the blocking plate 300 from falling.

[0055] Furthermore, a reinforcing portion 320 is provided on the surface of the blocking plate body 310. Exemplarily, the reinforcing portion 320 is protruding from the surface of the blocking plate body 310, and is a strip-shaped plate-like structure extending along the first direction. In the present embodiment, two reinforcing portions 320 are provided on both long sides of the blocking plate body 310, and the two reinforcing portions 320 are arranged at intervals. By providing the reinforcing portion 320, the structural strength of the blocking plate 300 can be increased and the blocking plate 300 can be prevented from deformation. Optionally, the reinforcing portion 320 is provided at the first avoidance opening 330. In addition, the reinforcing portion 320 can limit the displacement of the blocking plate 300 in the second direction (the width direction of the adapter 200), and when the blocking plate 300 moves along the second direction, the blocking piece 220 can abut against the reinforcing portion 320.

[0056] Further, see Figure 1 , Figure 6 and Figure 7 The air duct joint 410 is connected to the air duct 420 through the clamp 430. Exemplarily, the air duct joint 410 is a constricted type, one end connected to the air duct 420 is a circular opening, and one end connected to the bellows is a rectangular opening.

[0057] Furthermore, one end where the duct joint 410 and the adapter 200 are connected has an extension plate 411, and a second avoidance opening 412 is provided at the edge of the extension plate 411. The second avoidance opening 412 enables the edge of the extension plate 411 to form a second flange 413. The connecting piece can pass through the first assembly hole 221, the second avoidance opening 412 and the second assembly hole in sequence, and the connecting piece can support the second flange 413.

[0058] In this embodiment, the second flanges 413 are arranged on two long sides of the extension plate 411, and each long side is provided with three second flanges 413, and adjacent second flanges 413 are arranged at intervals, thereby forming a first avoidance opening 330. Since the air duct joint 410 and the blocking plate 300 are both connected to the adapter 200, the sizes of the second flange 413 and the second avoidance opening 412 can be set to the sizes of the first flange 340 and the first avoidance opening 330, respectively.

[0059] Furthermore, the present embodiment also provides an integrated stove, comprising the above-mentioned reversible bellows structure and a fan, wherein the fan is located inside the bellows main body 100 .

[0060] The integrated stove provided in this embodiment is provided with adapters 200 at both ends of the bellows main body 100, and with blocking plates 300 and air duct joints 410 that can be adapted to the adapters 200. When the air outlet needs to be changed, only the blocking plates 300 and the air duct joints 410 need to be replaced. The air duct 420 is installed on the air duct joint 410 without disassembly, which is very convenient. Only one air duct 420 is used for two air outlets, which is simple in structure and saves production costs.
