In the related art, a range hood generally includes a body and a fan, a smoke exhaust passage is formed inside the body, and the fan is disposed in the smoke exhaust passage. When smoke is discharged, the fan is started, and under the action of the fan, the oil smoke in the kitchen can enter the smoke discharge channel and then is discharged outdoors, so that the cleaning of the air in the kitchen is ensured.

But the fan is at the in-process of work, and fan impeller and fan motor's rotation can produce violent vibration noise, so can influence user's experience.

Based on this, as shown in fig. 1, the present application provides a fanless engine oil smoke machine 10, specifically, as shown in fig. 2, including a machine body 100, a first ionization assembly 200 and a second ionization assembly 300, wherein a smoke discharging channel 110 is formed inside the machine body 100, and the smoke discharging channel 110 has a smoke inlet and a smoke outlet; as shown in fig. 3, the first ionization component 200 is disposed in the smoke exhaust channel 110, and the first ionization component 200 is used for communicating with positive dc current; the second ionization assembly 300 is disposed in the smoke exhaust channel 110, and the second ionization assembly 300 is configured to be in direct current communication with the negative electrode, along the extending direction of the smoke exhaust channel 110, and along the direction (X direction in fig. 3) in which the smoke inlet points to the smoke outlet, where the first ionization assembly 200 and the second ionization assembly 300 are sequentially arranged at intervals, so that air in the smoke exhaust channel 110 sequentially passes through the first ionization assembly 200 and the second ionization assembly 300.

Through the above arrangement, when the oil smoke is required to be discharged, the positive direct current is conducted to the first ionization component 200, and the negative direct current is conducted to the second ionization component 300, so that the first ionization component 200 can generate positive ions, and the air near the first ionization component 200 generates negative ions, and the air near the second ionization component 300 generates negative ions, so that the positive ions can move towards the negative ions under the attraction of the negative ions, and in the moving process, the positive ions can strike other air molecules in the moving path of the positive ions, and the air in the smoke discharging channel 110 is generated, so that the air in the smoke discharging channel is discharged to the outside of the machine body 100 from the smoke discharging port. Thus, negative pressure is generated in the smoke discharging channel 110, and under the action of the negative pressure, the oil smoke outside the machine body 100 can enter the smoke discharging channel 110 through the smoke inlet and is discharged to the outside through the smoke discharging channel 110. Thus realizing smoke exhaust.

Through setting up the second output transformer, turn into required positive pole direct current and negative pole direct current with conventional user's electricity 220V to realize the ionization to the air, and then realize discharging fume. The third ionization assembly 400 and the fourth ionization assembly 500 are conveniently powered by providing a second row of output transformers.

In some embodiments, as shown in fig. 11, the third ionization assembly 400 includes at least one second conductive wire 410.

Through the above arrangement, the second conductive wire 410 has a smaller volume, so that it does not affect the air circulation at the smoke inlet 121, and can ionize the air, and the design is simple and convenient.

Of course, the third ionization assembly 400 may also include any other suitable component capable of communicating positive current, such as a conductive metal plate. This application is not hereby set forth in any detail.

In contrast to the second conductive wire 410 being disposed outside the machine body 100, the second conductive wire 410 being disposed inside the machine body 100 can avoid the user from contacting the second conductive wire 410, thereby ensuring the safety of the user.

On the basis, as shown in fig. 11, the fourth ionization assembly 500 includes a second conductive metal barrel 510 disposed in the smoke exhaust passage 110, a second ventilation passage 511 is formed on the second conductive metal barrel, a first end of the second ventilation passage 511 is communicated with the smoke exhaust passage 110, and a second end of the second ventilation passage 511 is communicated with the smoke inlet 121.

Through the above-mentioned setting, the inner wall of second ventilation passageway 511 can be abundant with the air contact in it to produce more negative ions, the positive ion of attraction that can be better makes its produced air current bigger, thereby guarantees its smoke discharging effect.

Of course, the fourth ionization assembly 500 may also include a conductive metal plate or a conductive wire, so long as the conductive wire is conductive and can generate enough suction force to drive air to flow, which is not illustrated herein.

When the third ionization component 400 and the fourth ionization component 500 are disposed at each smoke inlet 121, in order to enable the oil smoke passing through the smoke inlet 121 to flow toward the first ionization component 200, as shown in fig. 12, an end face of the second conductive metal barrel 510 far away from the fourth ionization component 500 is an inclined plane, and an included angle B is formed between the inclined plane and the flow direction of the oil smoke in the second ventilation channel 511, and is 75 degrees or more and is less than or equal to 85 degrees, so that the oil smoke passing through the smoke inlet 121 can be enabled to flow toward the first ionization component 200 and the second ionization component 300, and the oil smoke can be collected better, thereby facilitating the discharge of the oil smoke.

Of course, B may be any other suitable angle.

In order to facilitate the arrangement of the second conductive metal wire 410, as shown in fig. 12, the blower fan assembly 10 further includes an insulating cover 600, the insulating cover 600 is disposed in the smoke exhaust channel 110 and is fixedly connected with the first smoke collecting hood 120, for example, by gluing, fastening with screws, etc., a flue 610 is formed in the insulating cover 600, the insulating cover 600 is fastened at the smoke inlet 121, one end of the flue 610 is communicated with the smoke inlet 121, the other end of the flue 610 is communicated with the second end of the second air passage 511, and the second conductive metal wire 410 penetrates through a wall plate of the insulating cover 600 and extends into the flue 610.

By providing the insulating cover 600, the fume passing through the fume inlet 121 can only enter the second ventilation channel 511 through the fume duct 610, and the fume exhausting effect is increased. Meanwhile, since the second conductive wire 410 extends into the flue 610 through the wall plate of the insulating cover 600, the arrangement and fixing of the second conductive wire 410 are also facilitated. And, since the insulating cover 600 is insulated, the positive current on the second conductive wire 410 is prevented from being conducted to the machine body 100, thereby improving the safety performance of the range hood 10 without fan.

On this basis, in order to further improve the smoke discharging effect, as shown in fig. 13, the above-mentioned ventilator-free engine oil smoke machine 10 further includes a second smoke collecting hood 700, where the second smoke collecting hood 700 is disposed in the smoke discharging channel 110 and between the first ionization component 200 and the fourth ionization component 500, so that the smoke passing through the fourth ionization component 500 can be further collected under the action of the second smoke collecting hood 700, thereby improving the smoke discharging effect.

For a clearer understanding of aspects of the present application, the following description is provided in a specific implementation.

When the oil smoke is required to be discharged, firstly, the power panel is communicated with a power supply;

then, the power panel is communicated with the first row of output transformers, so that 220V voltage is converted into positive direct current and negative direct current which are not lower than 50000V, and the positive direct current and the negative direct current are respectively conducted to the first conductive metal wire 210 and the first conductive metal barrel 310, and air in the smoke exhaust channel 110 is driven to flow, and smoke exhaust is realized;

meanwhile, the power panel is connected with the second row output transformer, so that 220V voltage is converted into positive direct current and negative direct current which are not lower than 20000V, and the positive direct current and the negative direct current are respectively conducted to the second conductive metal wire 410 and the second conductive metal barrel 510, and air at the smoke inlet 121 is driven to flow, and the smoke discharging efficiency is enhanced.

On the basis, the application also provides a control method of the fanless engine oil smoke machine 10, wherein the fanless engine oil smoke machine 10 further comprises a controller, and the controller is electrically connected with the first conductive metal wire 210; as shown in fig. 14, the control method of the non-fan range hood 10 includes:

step S101: the controller receives a control instruction;

step S102: the controller controls the one or more first conductive wires 210 to be in direct current communication with the positive electrode according to the control instruction.

Through the arrangement, a user can send a control instruction to the controller according to the requirement, and after receiving the control instruction, the controller can control one or more first conductive metal wires 210 to be communicated with the positive electrode direct current, so that the smoke discharging capacity is controlled, and as the number of the first conductive metal wires 210 communicated with the positive electrode direct current is increased, the air ionization capacity of the first conductive metal wires 210 can be increased, and the smoke discharging capacity is improved. Through the above arrangement, the adjustment of the exhaust capacity of the blower less machine 10 is achieved.

When the exhaust capacity of the blower fan less engine 10 is adjusted, the first conductive wire 210 may be turned off or on at intervals when the first conductive wire 210 is turned on or off so that the on/off of the first conductive wire 210 does not affect the uniformity of ionized air. For example, 10 first conductive wires 210 are disposed along the first direction, and the range hood 10 is set to two low-range and high-range positions, wherein the 1 st, 3 rd, 5 th and 7 th first conductive wires 210 can be conducted in the low-range, and all the second conductive wires 410 can be conducted in the high-range. Since the first conductive wires 210, which are turned on in the low stage, are spaced apart, uniformity of ionized air can be ensured in the first direction.

The foregoing is merely a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
