Problems solved by technology

[0003] In related technologies, the air volume of the range hood is gradually increased, but the noise generated by it is also getting louder
When the range hood is turned on during cooking, voices, telephone calls, doorbells and children’s voices can hardly be heard. Even this kind of strong noise will cause kitchen operators to have irritability, headaches, palpitations and other adverse reactions. If people use strong noise for a long time Range hoods will seriously affect people's physical and mental health

Embodiment 1

[0027] Such as Figure 1 to 3 As shown, this embodiment provides a noise reduction structure for a range hood. The range hood includes a hood body 1 with an air inlet, and an oil net 2 is provided at the air inlet of the hood body 1. A fan 3 is arranged inside, a plurality of partitions 4 are arranged between the oil net 2 and the fan 3, and a vent 5 is opened on the partition 4 or formed between the partition 4 and the side wall of the hood body 1. The vents 5 are arranged staggered up and down.

[0028] In this embodiment, the range hood includes a hood body 1 with an air inlet, an oil net 2 is provided at the air inlet of the hood body 1, a fan 3 is installed in the hood body, and the fan 3 works to The external oil fume is introduced into the hood body 1 from the air inlet of the hood body 1, and a plurality of partitions 4 are arranged in the hood body 1 and between the oil net 2 and the fan 3 to prevent the fan 3 from working The noise is directly transmitted to the outsi...

Embodiment 2

[0041] Such as Figure 1 to 3 As shown, this embodiment provides a range hood, which includes the noise reduction structure of the range hood as described in the first embodiment.

[0042] In this embodiment, the hood main body 1 with an air inlet is included, an oil net 2 is provided at the air inlet of the hood main body 1, a fan 3 is arranged in the hood main body 1, and between the oil net 2 and the fan 3 The range hood noise reduction structure as described in the first embodiment is arranged between the range hood, and the range hood noise reduction structure as described in the first embodiment is arranged between the oil net 2 and the fan 3, which can make the range hood To ensure strong wind power, the range hood can also be used to block the noise generated by the fan 3, so that the noise is reflected, and the sound is reduced downward to prevent the noise from being directly transmitted through the oil net 2 to the outside of the hood body 1. At the same time, it can ...

Abstract

The invention discloses a noise reducing structure of a range hood and the range hood. The range hood comprises a range hood main body with an air inlet; an oil net is arranged in the air inlet of therange hood main body; a fan is arranged in the range hood main body; multiple separation plates are arranged between the oil net and the fan at intervals; ventilation ports are formed in the separation plates, or the ventilation ports are formed between the separation plates and the side walls of the range hood main body; and the ventilation ports are staggered up and down. The noise reducing structure is simple in structure, can enable the range hood to achieve the sound insulating and absorbing functions, and further improves the noise reducing effect of the range hood.

Description

Technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a noise reduction structure of a range hood and a range hood. Background technique [0002] In recent years, the hood market has been focusing on the concept of large air volume and large suction. With the improvement of people’s quality of life, users pay more and more attention to the noise parameters of the hood when purchasing range hoods. It can be said that the noise performance of the hood The quality of products is a key factor in product competitiveness. [0003] In related technologies, the air volume of the range hood is gradually increasing, but the noise generated by it is also increasing. When the cooker hood is turned on during cooking, you can hardly hear the voices, phone calls, doorbells, and children's sounds. Even this strong noise can cause irritability, headaches, heart palpitations and other adverse reactions to the kitchen operators. If people use str...
