Description

Technical Field

[0001] This invention relates to a range hood, and more particularly to an air-conditioning type range hood and its control method. Background Technology

[0002] To address the problem of stuffy kitchens during summer cooking, the cooling range hood was invented. This type of hood adds an air conditioning component to the existing range hood platform, combining the functions of a range hood with those of an air conditioner. The compressor, condenser, and evaporator of the air conditioning component are connected via refrigerant piping. When cooking, if the user is standing in front of the stove and enjoying the cool air from the air conditioner, the airflow angle is relatively large, and the air conditioner's trajectory tends to brush against the decorative cover. This causes cooking fumes to be easily disturbed by the air conditioner's airflow, resulting in smoke escaping and blowing onto the user's face. To improve the smoke extraction effect of conventional range hoods, lift-type range hoods have been invented, such as the "Lift-Type Range Hood" disclosed in Chinese invention patent application No. 202410039394.5 (publication number CN117781333A). In this lift-type range hood, the lower casing moves up and down relative to the upper casing, and the air inlet moves up and down relative to the lower casing. A fan is installed in the upper casing, and the air inlet has a smoke inlet. When the air inlet descends, the negative pressure zone shifts downward, improving the smoke extraction effect. When the air inlet rises, the entire machine has a compact structure and a small size. Although this lift-type range hood can improve the smoke extraction effect by lowering the air inlet, for air conditioning-type range hoods, it is necessary to pay attention to how to coordinate the lifting movement of the air inlet with the air outlet module to avoid the air conditioning air interfering with the airflow of cooking fumes while blowing towards the user. Summary of the Invention

[0003] The first technical problem to be solved by the present invention is to provide an air-conditioning type range hood that can ensure the effect of removing cooking fumes while the user is exposed to air conditioning.

[0004] The second technical problem to be solved by the present invention is to provide a control method for the above-mentioned air-conditioning type range hood, in view of the current state of the prior art.

[0005] The technical solution adopted by the present invention to solve the first technical problem mentioned above is as follows: an air-conditioning type range hood, comprising a housing, an oil fume extraction module and an air conditioning module installed inside the housing, an air outlet module that cooperates with the air conditioning module installed on the housing, and an air inlet installed at the bottom of the housing, the air inlet having an air inlet, characterized in that: the air inlet can move up and down relative to the housing under the drive of a driving mechanism, an oil fume sensor is installed on the housing, a temperature sensor is installed on the air inlet, and a controller is also included, the controller being able to receive the output signals of the oil fume sensor and the temperature sensor, and accordingly control and adjust the air outlet angle of the air outlet module and the lifting stroke of the air inlet based on the received signals.

[0006] Preferably, the housing includes an upper housing and a lower housing located at the bottom of the upper housing, and the air inlet is located at the bottom of the lower housing and can move up and down relative to the lower housing.

[0007] In a further preferred embodiment, the air inlet is located at the bottom rear side of the lower housing.

[0008] To achieve two-stage lifting of the air inlet, the air inlet body includes a first lifting body and a second lifting body. Driven by the drive mechanism, the first lifting body can move up and down relative to the lower housing, and the second lifting body can move up and down relative to the first lifting body. The air inlet is located on the second lifting body. In the fume extraction mode, the first lifting body can extend downward below the lower housing, and the second lifting body can extend downward below the first lifting body. In the off mode, the second lifting body can rise up into the interior of the first lifting body.

[0009] The fume sensor can be installed in multiple different locations. Preferably, the fume sensor is located on the front side of the lower housing.

[0010] Temperature sensors are installed in multiple different locations; preferably, the temperature sensor is located at the air inlet.

[0011] In order to enable the left and right air inlets of the range hood to rise and fall independently according to the cooking conditions of the left and right stoves, the air intake body includes a left air intake body and / or a right air intake body that can be raised and lowered independently. Correspondingly, the air inlet includes a left air inlet and a right air inlet, and the temperature sensor includes a left temperature sensor and / or a right temperature sensor.

[0012] The drive mechanism can have various structures. Preferably, the drive mechanism includes a motor and a lead screw that rotates under the drive of the motor. The motor is mounted on the lower housing and located at the back of the lower housing, and the lead screw is mounted on the air inlet and located at the back of the air inlet.

[0013] In order to ensure that the air outlet of the air outlet module can blow out cold air smoothly, the air conditioning module includes a compressor, a condenser, an evaporator, a cooling fan and an indoor unit fan. The compressor, condenser and evaporator are connected through refrigerant pipelines, and the air outlet of the indoor unit fan is fluidly connected to the air outlet of the air outlet module through the indoor unit air duct.

[0014] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: a control method for an air-conditioning type range hood, which is applied to the aforementioned air-conditioning type range hood, and the control method includes the following steps:

[0015] S1. The range hood is turned on;

[0016] S2. Determine if the air conditioner is on;

[0017] If so, the drive mechanism drives the air intake body to descend and makes the air intake port a first set distance from the table surface, and then proceeds to step S3;

[0018] If not, the drive mechanism drives the air inlet to descend and makes the air inlet a second set distance from the table surface. The second set distance is greater than the first set distance, and then proceeds to step S8.

[0019] S3. Determine whether to enter cooking mode;

[0020] If so, proceed to step S4;

[0021] If not, then perform the action in step S2 when the air conditioner is on;

[0022] S4. Determine if the fume sensor has been triggered;

[0023] If so, proceed to step S5;

[0024] If not, then perform the action in step S2 when the air conditioner is on;

[0025] S5. Determine whether only the left or right temperature sensor is triggered.

[0026] If so, the air inlet on the corresponding side will descend to a third set distance from the table surface, which is less than the first set distance, and the air inlet on the other side will rise.

[0027] If not, proceed to step S6;

[0028] S6. Determine if the temperature sensor on the other side has been triggered;

[0029] If so, the air inlet on that side will descend to the third set distance from the tabletop, while the air inlet on the other side will rise.

[0030] If not, proceed to step S7;

[0031] S7. Determine whether both the left and right temperature sensors are triggered;

[0032] If so, both the left and right air inlets will descend to the third set distance from the tabletop, and then proceed to step S8;

[0033] If not, return to step S3;

[0034] S8, End.

[0035] Compared with the prior art, the advantages of the present invention are as follows: the air inlet of the air-conditioning range hood can move up and down relative to the casing under the drive of the drive mechanism. The controller can receive the output signals of the oil fume sensor and the temperature sensor, and control and adjust the air outlet angle of the air outlet module and the lifting stroke of the air inlet according to the received signals. Thus, in the cooking state, in order to allow the cook to be blown by the air conditioner, the air guide angle is adjusted to a larger value. At this time, the air inlet is lowered, so that the negative pressure zone is closer to the pot, which can avoid the air conditioner from interfering with the oil fumes, thereby enhancing the oil fume extraction effect.
