Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 5, the range hood of the present embodiment includes a housing 1 and a fan system 2 disposed in the housing 1. The lower part of the shell 1 is provided with a vertically extending smoke inlet cavity 11, the front side wall of the lower part of the shell 1 is provided with a smoke inlet 111 communicated with the smoke inlet cavity 11, the upper part of the shell 1 is provided with a smoke collecting cavity 12 communicated with the smoke inlet cavity 11, the smoke collecting cavity 12 extends forwards to form a mounting cavity 13 for mounting the fan system 2, it should be noted that the mounting cavity 13 is used for mounting the fan system 2, but the mounting position of the fan system 2 is not completely limited in the mounting cavity 13, and because the smoke collecting cavity 12 and the mounting cavity 13 are integrated, when the fan system 2 is mounted, the part of the fan system 2 can be positioned in the smoke collecting cavity 12 according to requirements. The air inlet 21 of the fan system 2 may be arranged in advance or in the rear direction, as long as it is communicated with the smoke collecting cavity 12, and the air outlet 22 of the fan system 2 is arranged upward. An oil collecting cup 4 with an upward opening is arranged at the lower edge of the shell 1, and the bottom of the smoke inlet cavity 11 is connected with the oil collecting cup 4. Because the smoke inlet cavity 11 at the lower part of the shell 1 vertically extends, the smoke inlet cavity 11 can be made thinner along the width in the front-back direction and can extend downwards to be sufficiently close to the cooker and a smoke generating source, so that the smoke can be quickly sucked into the smoke inlet cavity to be discharged upwards once being generated, and the smoke suction effect is improved.

In this embodiment, a sensor 5 capable of detecting the temperature of the oil smoke is disposed at the junction of the smoke inlet cavity 11 and the smoke collecting cavity 12, and the sensor 5 is an NTC sensor. The sensor 5 is detachably arranged in the middle of the front side wall at the upper end of the smoke inlet cavity 11 through a mounting component 6. Because the smoke inlet 111 of the range hood is close to the smoke source of the range, the temperature at the smoke inlet 111 is generally higher than the temperature in the smoke cavity, and if the smoke inlet 111 is used as the arrangement point of the NTC sensor, certain interference exists for the detection and judgment of the temperature, and the risk of misjudgment exists, so that the sensor 5 is installed at the upper end of the smoke inlet cavity 11 in the embodiment, and the smoke temperature can be detected more accurately.

The assembly component 6 of the embodiment includes a first assembly plate 61 and a second assembly plate 62, a clamping opening 611 for the sensor 5 to pass through and clamp the sensor 5 is opened in the middle of the first assembly plate 61, correspondingly, an open slot 621 is opened on the second assembly plate 62 and extends downwards from the upper edge and supports the tail of the sensor 5 thereon, and the first assembly plate 61 and the second assembly plate 62 are relatively buckled and connected. During installation, the front end of the sensor 5 penetrates through the clamping opening 611 on the first assembling plate 61, the rear end of the sensor 6 is aligned to the open groove 621, the first assembling plate 61 and the second assembling plate 62 are buckled with each other, and the tail part of the sensor 5 is just erected on the bottom wall of the open groove 621, so that the installation stability of the sensor 5 is improved. Meanwhile, the opening groove 621 facilitates the wiring. The second assembly plate 62 is provided with a receiving groove 622 around the lower edge of the opening groove 621 on the side wall near the first assembly plate 61, a sealing ring 63 is sleeved on the outer periphery of the tail portion of the sensor 5, and the sealing ring 63 is embedded in the receiving groove 622 when the first assembly plate 61 and the second assembly plate 62 are in a mutually-combined state. This structure contributes to further improving the mounting stability of the sensor 5. The first assembly plate 61 is provided with a socket 612 located at a side of the clamping opening 611, and correspondingly, the second assembly plate 62 is provided with a plug post 623 protruding and fittingly connected with the socket 612. The inserting column 623 and the inserting hole 612 are connected in a tight fit mode after being inserted and connected with each other, and the assembling mode is simple and convenient to operate. The fan frame 131 for installing the fan system 2 is disposed in the installation cavity 13 of the present embodiment, the lower end of the fan frame 131 extends to the upper end of the smoke inlet cavity 11, and the assembling component 6 is fixed on the front side wall of the fan frame 131 through screws.

In the present embodiment, a panel 14 capable of opening or closing the smoke inlet 111 is disposed on the smoke inlet 111, a driving mechanism capable of driving the panel 14 to turn is disposed in the housing 1, and the driving mechanism and the sensor 5 are controlled by the same control system. When the sensor 5 detects that the temperature of the lampblack is too high, the control system can control the driving mechanism to turn over the panel 14 and close the smoke inlet 111, so that the lampblack absorber is prevented from being continuously sucked.

When the range hood of the embodiment is used, the sensor 5 monitors the temperature of oil smoke in the range hood in real time, when the temperature of the oil smoke reaches 80 ℃ and continuously rises by 15 ℃ in 5S or the temperature of the oil smoke reaches 120 ℃, a signal is fed back to the control system, the control system controls the fan system to stop running, and meanwhile, the panel 14 is turned over to close the smoke inlet 111, so that a flue in the range hood is isolated from the outside, and fire extinguishment is realized; when the sensor 5 detects that the oil smoke does not meet the conditions, the range hood keeps normal operation.
