Problems solved by technology

[0003] At present, the muffler traditionally applied to the air-conditioning pipeline is limited in the muffler range, which causes the air flow pulsation to interact with the muffler wall to form a resonance, which reduces the muffler effect and seriously affects the user experience.

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0024] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "fixed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "righ...

Abstract

The invention discloses a silencer and an air conditioner. The silencer comprises a first silencing structure, a second silencing structure and a separating plate, and the first silencing structure comprises an air inlet pipe, an air outlet pipe and a silencing part; the silencing part comprises a first expansion cavity and at least two through holes formed in the side wall of the first expansioncavity, and the air inlet pipe and the air outlet pipe communicate with the first expansion cavity; the second silencing structure comprises a second expansion cavity, and the first silencing structure is arranged in the second expansion cavity; the separating plate is arranged between the outer wall of the first silencing structure and the inner wall of the second expansion cavity, and the secondexpansion cavity is divided into a first cavity body and a second cavity body through the separating plate; and the first cavity body communicates with the first expansion cavity through at least onethrough hole, and the second cavity body communicates with the first expansion cavity through at least one through hole; and the separating plate can be moved relative to the first silencing structure so that the volumes of the first cavity body and the second cavity body are adjustable. According to the silencer, full-band silencing can be achieved, and the silencing effect is good.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a muffler and an air conditioner. Background technique [0002] The muffler refers to the airflow pipeline with noise transmission at the same time, the noise reduction device can be used to attenuate the noise in the pipeline by using the pipeline with the sound-absorbing lining and the elbow or the pipeline with a sudden change in the cross-sectional area and other pipelines with discontinuous acoustic impedance. or reflect back. The former is called a resistive muffler, the latter is called a resistive muffler, and there are also impedance composite mufflers. [0003] At present, the mufflers traditionally used on air-conditioning pipelines are limited in the muffler range, resulting in the interaction between the air flow pulsation and the muffler wall to form resonance, which reduces the muffler effect and seriously affects the user experience.
