Description

Technical Field

[0001] The invention relates to a range hood, in particular to an air-conditioning type range hood and a control method thereof. Background Art

[0002] In order to solve the pain point of the stuffy kitchen when cooking in summer, people invented the refrigeration range hood. The refrigeration range hood adds an air conditioning component on the basis of the range hood platform, which can realize all the functions of the range hood and the function of the air conditioner. The compressor, condenser and evaporator of the air conditioning component are connected through the refrigerant pipeline. When the user is cooking, the user stands in front of the stove and enjoys the cold air from the air conditioner. At this time, the wind guide angle is large, and the air conditioning wind trajectory is easy to stick to the decorative cover. At this time, the cooking fumes are easily disturbed by the air conditioning wind, forming a smoke leakage phenomenon and blowing on the user's face. For conventional range hoods, in order to improve the oil fume extraction effect, people have invented a lifting range hood, such as the "Lifting Range Hood" disclosed in the Chinese invention patent application with application number 202410039394.5 (application publication number CN117781333A). The lower box of the lifting range hood performs lifting movement relative to the upper box, and the air inlet body performs lifting movement relative to the lower box. A fan is installed in the upper box, and the air inlet body has a smoke inlet. When the air inlet body descends, the negative pressure area moves downward to improve the oil fume extraction effect. When the air inlet body rises, the whole machine has a compact structure and a small size. Although the lifting range hood can improve the oil fume extraction effect by lowering the air inlet body, for air-conditioning range hoods, it is necessary to pay attention to how to coordinate the lifting movement of the air inlet body with the air outlet module to avoid interference with the oil fume airflow while the air conditioning wind is blowing towards the user. Summary of the invention

[0028] S6, determining whether the temperature sensor on the other side is triggered;

[0029] If so, the corresponding air inlet on that side is lowered to a third set distance from the tabletop, and the air inlet on the other side is raised;

[0030] If not, proceed to step S7;

[0031] S7, determining whether both the left temperature sensor and the right temperature sensor are triggered;
