AI Technical Summary
The exhaust system of existing integrated stoves has turbulence in its design, which leads to large loss of air volume and air pressure, increased noise, and oil smoke can easily blow out from the oil leakage port and pollute the interior, affecting the user experience.
A fan system that can be rotated 180° is adopted, and the air duct structure is eliminated to achieve direct exhaust. The fan system is supported by fixed brackets and support brackets that are symmetrically distributed on the left and right inside the bellows to ensure smooth exhaust. The combination of the air guide ring and the volute provides centrifugal force to discharge the oil smoke.
It achieves smooth smoke exhaust, reduces design and production requirements, and the air outlet is conveniently reversible to avoid oil smoke contamination inside the integrated stove, thereby improving user experience.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of integrated stoves, in particular to a reversible direct-exhaust integrated stove. Background Art
[0002] The exhaust system of a conventional integrated stove mainly consists of an "air box" and an "air duct". The air box generates negative pressure through the internal fan assembly, sucks the cooking fumes into the air box, and then the centrifugal force of the fan assembly discharges the fumes into the connected air duct. Finally, the fumes are discharged according to the exhaust direction of the integrated stove installation.
[0003] Due to spatial structure reasons, the centrifugal fan unit is horizontally placed in the air box. When the fumes enter the fan assembly, the fumes vertically enter the horizontally placed air duct along the volute. The exhaust process requires a 90° turn, resulting in turbulent flow of the fume gas discharged into the air duct, large losses in air volume and air pressure, and an increase in noise. Under the same conditions, the energy consumption also increases, causing unsmooth exhaust during operation and reducing the user experience. In existing integrated stoves, the oil leakage port is generally placed at the bottom of the air duct. During operation, positive pressure is generated in the air duct, and under the action of the positive pressure, fume gas is directly blown out from the oil leakage port, causing internal pollution of the integrated stove and generating odors in the kitchen. Content of the Utility Model
[0004] The purpose of the utility model is to provide a reversible direct-exhaust integrated stove to solve the above problems.
[0005] To achieve the above purpose, the utility model is implemented by adopting the following technical solutions. A reversible direct-exhaust integrated stove, characterized by comprising a machine body (1), an air box (2), a rear machine body plate (3), and a fan system; on the left and right sides inside the air box, there are fan system fixing brackets (4), and at the bottom, there is a support bracket (6). The left and right sides of the air box (2) are provided with air outlets; the fan system includes a wind wheel (7), a wind guide ring (8), a volute (9), and an air duct base (10). The fan system is arranged in the air box (2), placed on the support bracket (6), and fixed to one side of the fan system fixing bracket (4); the fan system can be rotated 180° for reversible installation. One side of the air outlets on the left and right sides of the air box (2) is used to fix the air duct base (10), and the other side is fixed and sealed with a baffle (5). The air duct base (10) is horizontally externally connected to an exhaust pipe. Adopting the direct-exhaust method, the air duct structure is cancelled, eliminating the 90-degree turn in the exhaust passage, making the exhaust smooth and preventing fume gas from flowing out and polluting the interior of the integrated stove.
[0006] In the above structure, when the smoke exhaust direction needs to be reversed, remove the rear plate (3) of the body from the body (1), remove the fixing screws of the duct seat (10) on one side of the air outlet and the fixing screws of the baffle (5) on the other side, then remove the two screws fixed on the fixed bracket (4) of the fan system. After pulling out the fan system, turn it 180°. Fix the outlet screw on one side of the duct seat (10) and fix the baffle (5) with screws on the other side. Fix the rear plate (3) of the body on the body (1) with screws.
[0007] Further, the fixed bracket (4) of the fan system is connected to the air box (2) by screws and is symmetrically distributed on the left and right.
[0008] Further, there are two support brackets (6), which are connected to the air box (2) by screws and are symmetrically distributed on the left and right.
[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: smooth smoke exhaust, reducing the requirements for design and production, realizing convenient reversal of the air outlet of the integrated range hood, and meeting the adjustable left and right air outlet.

[0013] The present utility model will be further described in detail below with reference to the drawings.
[0014] As Figure 1As shown, the reversible straight-discharge integrated stove includes a body 1, a bellows 2, a body rear plate 3, and a fan system. The left and right sides of the bellows 2 are provided with fixed fan system brackets 4 that are symmetrically distributed on the left and right, and the bottom is provided with support brackets 6 that are symmetrically distributed on the left and right; the left and right sides of the bellows 2 are provided with air outlets, one side of the air outlet is used to fix the air duct seat 10, and the other side is fixed and sealed with a baffle 5. The fan system is inside the bellows 2, including a wind wheel 7, an air guide ring 8, a volute 9, and an air duct seat 10. The bottom is placed on the support bracket 6, and one side of the upper end is fixed on the fan system fixed bracket 4. The fan system is driven by a motor to rotate the wind wheel 7, and the inside of the bellows 2 is under an overall negative pressure. The oil smoke enters the bellows 2, and the oil smoke is guided into the volute 9 through the air guide ring 8. The centrifugal force is then provided by the wind wheel 7, and the oil smoke flows out to the air duct seat 10 along the volute curve, and is discharged through a horizontal external exhaust pipe. The utility model adopts a direct exhaust method, cancels the air duct structure, eliminates the 90-degree turn in the smoke exhaust channel, makes the smoke exhaust smoother, and also solves the problem of smoke escaping from the oil leakage port and polluting the inside of the integrated stove.
[0015] When it is necessary to reverse the direction of smoke exhaust, remove the body rear panel 3 from the body 1, remove the fixing screws of the duct seat 10 on one side of the air outlet and the fixing screws of the baffle 5 on the other side, and then remove the two screws fixed on the fan system fixing bracket 4. After pulling out the fan system, turn it 180° and install it again, fix the outlet screws on one side of the duct seat 10 and the baffle 5 with another screw, and fix the body rear panel 3 to the body 1 with screws.
