Description

Kitchen exhaust smoke air-compensating structure

Technical Field

The utility model relates to a kitchen fume extractor air-return structure, and belongs to the technical field of civil decoration engineering.

Background

The common residential building rarely considers the problem of the air supply and return of the smoke exhaust ventilator in decoration design and construction. The cooking habit of people in China adopts oil pan to cook dishes, in order to prevent oil smoke from running to a dining room, the habit is to close a door of a kitchen room, if the weather is hot or cold at this time, a window is generally closed, smoke is not smooth, the smoke is considered to be insufficient in power when the door or window of the kitchen room is opened, the smoke is quickly dispersed when the door or window of the kitchen room is opened, the smoke is equivalent to the air extraction from the kitchen room when the smoke is discharged in a relatively airtight space, a relatively negative air pressure environment is formed, and the positive air pressure formed by hot air in a flue causes the air backflow of the smoke to cause the smoke not to be discharged out, but the smoke is more discharged.

The user is used to window and exhaust smoke or open the door to supplement air through a dining room, such as a guest restaurant and a developed room window, the effect is not ideal, a central air conditioner is generally adopted in the existing residence, the general household is power-saving or afraid of dust running in, the general door and the window are closed, the smoke and air supplementing effect is poor due to the relatively sealed environment, and the constant temperature system created by the air conditioning system is destroyed, so that the energy consumption is increased. Although the air supplementing can be performed by opening the kitchen window, the formed side air effect is not ideal, and flying insects are easy to enter the room or dust accumulation of the screen window is easy to occur for a long time when the window is opened.

The nitrogen dioxide generated by the kitchen relative to the enclosed space during cooking is also unhealthy.

Disclosure of Invention

The technical problems to be solved by the utility model are as follows: under the condition that a kitchen room door or a window is not opened, the kitchen ventilator can supply timely air supply when working, or an open kitchen room can not run to a guest restaurant, and the indoor constant-temperature environment can not be damaged.

In order to solve the problems, the utility model provides a kitchen smoke exhaust and air return structure, which comprises a PVC air pipe, wherein one end of the PVC air pipe is an air return air outlet which is exposed from the indoor space, the other end of the PVC air pipe is connected with a PVC special-shaped detachable air pipe, and the end part of the PVC special-shaped detachable air pipe is an air return air inlet which is exposed from the outdoor space. The utility model adopts natural air supplementing, and the air supplementing quantity is calculated according to 80-95% of the smoke exhaust quantity.

Preferably, the opening of the air inlet of the back air is inclined downwards, so that rainwater is prevented from entering.

Preferably, a filter screen is arranged in the PVC special-shaped detachable air pipe.

Preferably, the air inlet for the supplementary return air is arranged below the kitchen windowsill, and the bearing system of the building is not damaged by the external opening.

Preferably, the air outlet of the back air is arranged on a kitchen cabinet skirting line below the gas stove.

More preferably, a detachable air port is arranged on the cabinet skirting line corresponding to the air outlet of the air compensating return.

Furthermore, the detachable air port is a shutter or an aluminum grille, and the integral style of the detachable air port and the cabinet should be kept consistent, so that the detachable air port is attractive and practical.

Preferably, the PVC air pipe is arranged in a cavity layer between the bottom plate of the cabinet and the ground.

More preferably, a support member for protecting the PVC air pipe is arranged in the cavity layer.

Preferably, the air inlet of the back air is provided with a rainproof and insect-proof cover.

Compared with the prior art, the utility model adopts a smoke exhaust ventilator air-return process structure, and by adopting the design of the utility model, the kitchen air pressure is balanced, the effect of rapid smoke exhaust is achieved, the health of families is protected, and the utility model also has the function of energy conservation.

Detailed Description

In order to make the utility model more comprehensible, preferred embodiments accompanied with figures are described in detail below.

Examples

As shown in fig. 1-3, the kitchen smoke exhaust and air return structure provided by the utility model comprises a PVC air pipe 1, wherein one end of the PVC air pipe 1 is an air return air outlet 2 which is exposed from the room, the other end of the PVC air pipe is connected with a PVC special-shaped detachable air pipe 3, and the end part of the PVC special-shaped detachable air pipe 3 is an air return air inlet 4 which is exposed from the room. The utility model adopts natural air supplementing, and the air supplementing quantity is calculated according to 80-95% of the smoke exhaust quantity. The opening of the air inlet 4 of the air return is inclined downwards, so that rainwater is prevented from entering. A filter screen 5 is arranged in the PVC special-shaped detachable air pipe 3. The air inlet 4 of the air supplementing back is provided with a rain-proof insect-proof cover 6.

The air inlet 4 for the air return is arranged below the kitchen windowsill, and the bearing system of the building is not damaged by the external opening. The air outlet 2 of the air-compensating return is arranged on a skirting line of a cabinet below the gas stove. The detachable air port is arranged on the kitchen cabinet skirting line corresponding to the air supply and return air outlet 2. The detachable air port is a shutter or an aluminum grille, and the integral style of the detachable air port and the cabinet should be kept consistent, so that the detachable air port is attractive and practical. The PVC air pipe 1 is arranged in a cavity layer between the bottom plate of the cabinet and the ground. According to the requirement, a supporting piece for protecting the PVC air pipe 1 can be additionally arranged in the cavity layer so as to strengthen the supporting structure.
