Abstract

The utility model discloses an improved air-curtain cooker hood. The air volume generated by blades of the prior air-curtain cooker hoods has the phenomenon of diffluence, which reduces air exhaust rate of an air-curtain air outlet and forms a limited air-curtain. The utility model is characterized in that the fore end part of an inner chamber of the case of an air-curtain cooker hood which is composed by a casing, a main motor, an air-curtain motor, an air channel, an oil ring, a lower cover, an oil cup, a control switch, an air exhaust pipe, etc. is arranged in addition, with a partition plate with a support frame with holes, the air-curtain exhausts air to have a function of diversion, the air-curtain extends, and the cook and cooking fume are effectively partitioned. The utility model is suitable for use in household kitchens.

Description

Air-curtain cooker hood

The utility model relates to a kind of range hood, particularly relates to a kind of wind curtain type range hood.

In Modern Family's cooking apparatus, the range hood of use mainly by be fixedly connected on shell, the output shaft by the motor of fan blade, in the shell air channel, oil ring, institutes such as cover, lubricating cup, gauge tap and discharge pipe form down.Though, used this range hood function to reduce the pollution of indoor oil smoke, also there is certain harm in the cooking operation person near oil smoke.The person avoids sucking contaminated gas in order to make the cooking operation, has set up exhaust outlet on the front end bottom surface of shell, has installed the air curtain motor in the enclosure additional.When using like this, promptly formed an air draft curtain between people's kitchen range, become invisible air screen, then, this is the desirable effect of no show also, because pass through the air quantity that fan blade produces on the air curtain motor output shaft, most of consumption shell and following the cover in the inner chamber that constitutes, only some is discharged by the air curtain exhaust outlet, forms a limited air draft curtain, is still endangering the healthy of cooking operation person.

The purpose of this utility model is that a kind of improved wind curtain type range hood will be provided, and eliminates above-mentioned weak point, realizes producing the effective air curtain of a row, guarantees health.

To achieve the above object, the utility model proposes the design of following wind curtain type range hood: this wind curtain type range hood comprises the shell that is provided with exhaust outlet, the main motor that has fan blade on the air curtain motor of fan blade and the output shaft is housed in the enclosure the output shaft of assembling, be sleeved on the outer air channel of main motor, device is at the oil ring of lower end, air channel, with holes and form the following cover be fixedly connected with the shell lower end, be assemblied in down the lubricating cup on the cover, be installed in gauge tap on the shell front end face and discharge pipe etc.The inner chamber front end that described shell and following cover are formed is provided with a division board, is shaped on support with holes on it.

Because the utility model has improved the structure of original wind curtain type range hood, increased by a division board at shell with the following hood-shaped inner chamber front end that becomes, so that air draft plays guide functions to air curtain, and prolongation air curtain, it is rational in infrastructure, can fully will intangibly keep apart between cooking operation person and oil smoke and the cooking waste gas, and help also that contaminated gas is more concentrated to be purified effectively.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structural representation of wind curtain type range hood of the present utility model.

Fig. 2 is the structural representation of the division board of wind curtain type range hood of the present utility model.

Fig. 3 is that schematic diagram is looked on the right side of Fig. 2.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the wind curtain type range hood that the utility model proposes.

Referring to Fig. 1, the housing of this wind curtain type range hood is made up of shell 3 and following cover 9.The end face of shell 3 has an exhaust outlet 1, exhaust outlet 1 is connected with a discharge pipe, one gauge tap 11 is housed on the front end face of shell 3, be shaped on the exhaust outlet 2 of a row space on the front end bottom surface of shell 3, it is the air curtain exhaust outlet, front end in the shell 3 is mounted with an air curtain motor 5, be equipped with fan blade on its output shaft, middle part in the shell 3 also fixedly is equipped with an air channel 6, be equiped with a main motor 4 in the air channel 6, be connected with fan blade on its output shaft, the lower end cooperation in air channel 6 is connected with an oil ring 7, the lower end mount of shell 3 is connected with and covers 9, is shaped on a hole 8 of matching with fan blade on main motor 4 output shafts on the following cover 9.Under cover and also be provided with a lubricating cup 10 on 9, the number of main motor 4 and air curtain motor 5 can be according to use occasion, doing increases accordingly.

Referring to Fig. 1, Fig. 2 and Fig. 3, division board 14 is thin plates of curved shape, its middle part is provided with a support 13, be drilled with hole 12 on the support 13, division board 14 is to be installed on the frame of air curtain motor 5 by the 12 usefulness bolting of the hole on its support 13, and will be kept apart by the fore-end and the remainder of shell 3 and following cover 9 inner chambers that constitute.

During cooking operation, start main motor 4 and air curtain motor 5 by pressing gauge tap 11, the air quantity that fan blade produces on the air curtain motor 5, blocked by division board 14, concentrate on the fore-end of housing inner chamber, discharge in several rows of air port from the shell 3 front end bottom surfaces 2 then, and form one row effective air curtain, the cooking waste gas that produces during the cooking operation person and the cooking is kept apart, the fan blade that is rotating on the main simultaneously motor 4, suck oil smoke and cooking waste gas, and by exhaust outlet 1 and discharge pipe to outdoor discharge, the cooking operation person promptly cooks delicious food under good environment.
