Description

Technical Field

[0001] The present invention belongs to the field of integrated stoves, and in particular relates to a fan system for an integrated stove. Background Art

[0002] Integrated stoves, as a commonly used household appliance, play an important role in people's lives. The grease separation degree, noise and energy-saving level of integrated stoves are important indicators for selecting integrated stoves.

[0003] At present, traditional integrated stoves generally filter grease through a single oil net when working. This method of filtering oil smoke is inefficient, and during the operation of the integrated stove, oil smoke is easily accumulated in the fan box, affecting the exhaust effect, and in serious cases, there is a risk of causing fire;

[0004] In addition, traditional integrated stoves usually use multi-blade centrifugal fans, which have large vibration and noise when in use. In addition, during use, the parameters of traditional integrated stoves are set to fixed values. However, for kitchen exhaust in traditional low-rise buildings, small apartments, and private customized places, the fan performance parameters are set too high, resulting in energy waste.

[0005] Conventional solutions to this problem often involve simple noise reduction measures such as increasing the frequency of oil screen cleaning. However, although such measures have certain effects, they are cumbersome to operate, difficult to disassemble, and require a lot of manpower to clean. Therefore, conventional settings cannot meet people's higher demands for integrated stove operation. Summary of the invention

[0006] In order to overcome the shortcomings of traditional integrated stoves such as low grease separation, high air intake noise and energy waste, the present invention provides a new fan system for integrated stoves, which reduces the effects of grease accumulation, air intake noise and energy waste on integrated stoves based on heat transfer knowledge and aerodynamic principles.

[0007] The technical solution adopted by the present invention to solve its technical problem is:

[0008] A novel fan system for an integrated stove comprises a fan box and an air intake body arranged in an air intake passage of the integrated stove; the fan box is located at the back of the integrated stove, and the size of the inlet of the fan box is consistent with that of the air intake body;

[0009] Taking the air intake direction as the positive direction, the air intake body includes a front device, an impeller, a motor, an air outlet pipe and an oil return pipe; the front device is an irregular polygonal structure observed from the cross-sectional direction, and is composed of six surfaces A, B, C, D, E, and F. The surfaces A, E, and F are the working surfaces for the oil supply fume to inhale the front device, and the surface B is the working surface for sucking out the front device; the front device includes an air intake mesh and a plurality of heat exchange pipes, and the air intake mesh is located on the upper and lower surfaces A, B and the two side surfaces E, F of the front device; the C and B surfaces of the front device are fixed to the inner wall surface of the air intake body; the heat exchange pipe is located in the space of the upper and lower surfaces A and B of the air intake mesh, and the two ends of the heat exchange pipe are fixed to the C and D surfaces of the front device; the impeller is located below the front device, one side of the impeller is fixed to the inner wall surface of the air intake body, and the other side is connected to the motor; the motor is fixed at the inner wall surface of the air intake body; the air outlet pipe is located at the end of the air intake direction of the body, and an oil return pipe is provided at the side end of the air intake body.

[0010] Furthermore, the upper and lower surfaces of the front device are specifically a rectangular thin plate, and rectangular air inlet holes are evenly distributed on the plate surface, and the distances between adjacent air inlet holes are equal.

[0011] Furthermore, the heat exchange tube is composed of several long tubes, whose cross-section is a circular structure with a radius of R1. Both ends of the heat exchange tube are fixed to the C and D surfaces of the front device. Refrigerant is injected into the tube. The distance between adjacent heat exchange tubes is equal, and the center lines of the heat exchange tubes in the front device are located in the same plane.

[0012] Furthermore, the impeller is an elongated cylindrical shape, and its impeller radius is R2 and its length is L1.

[0013] Preferably, the impeller used is a diagonal flow impeller, including a cylindrical multi-blade impeller rotor. The oil fume enters the impeller from the blade grid on one side of the rotor, passes through the inside of the rotor, and is discharged from the blade ridge on the other side of the rotor. The effective air volume of the impeller is 15.8m 3 / min, static pressure P is 60pa, the speed of the connected motor is 1400rpm, the connected voltage is 220 / 380V, and the motor parameter is 0.6A.

[0014] The air outlet pipe is located at the end of the air inlet direction of the main body, and is a rectangular structure when observed in the cross-sectional direction.

[0015] The oil return pipe is a circular hose with a radius of R3, which guides the oil accumulated in the arc groove of the main body out of the intake body.

[0016] Preferably, the fan box is a rectangular box.

[0017] In the present invention, the oil fume intake is separated by two layers of oil nets and heat exchange tubes; specifically, the oil fume can be sucked in from three sides of the front device A, E, and F, and after heat exchange with the heat exchange tube, it is sucked out of the front device from the B side, and its C and D side surfaces are closed surfaces, which are fastened to the inner wall of the intake body by bolts, and separated by double-layer filter screens and oil droplet condensation, thereby improving the oil separation degree.

[0018] The present invention is applicable to facilities such as row houses, linked villas, and low-rise places;

[0019] The beneficial effects of the present invention are:

[0020] (1) Multi-mesh oil filter improves the oil separation degree; (2) Heat exchange tubes are used to exchange heat with hot oil smoke to condense the oil and improve the oil separation degree; (3) The selected fan uses an oblique flow air intake method to reduce the air intake noise; (4) The selected fan has an enlarged air intake surface to reduce the accumulation of oil in the fan box; (5) This device is mostly fixed with bolts, and the device is easy to disassemble and clean.
