Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is an air with a noise suppression device that completely prevents the noise noise generated in an air conditioner or the like from flowing out and can always seek quiet air conditioning in the room. It is about a harmony machine.

[0002]

2. Description of the Related Art Normally, as means for supplying quiet calm and warm air to a room, it is attempted to suppress outflow of noise in the air into the room. Since it is intended only for the so-called muffling effect of reducing the noise, a muffling mechanism of an appropriate shape is provided in the air passage of the air conditioner, or a muffling chamber of the muffler provided with the muffling mechanism in the air conditioner main body. They had been lined up.

However, since all of the above are intended only for the sound deadening effect in the air, there is no effect as a sound insulation function, and therefore the noise generated by the air conditioner itself, For example, there is no countermeasure against the noise caused by noise when driving a blower, an electric motor or the like. Recently, as a countermeasure against such vibrations, it has been developed to attach a vibration-proof material of an appropriate shape directly to the vibration part of the blower or electric motor in order to improve the sound insulation effect, but most of these mechanisms are vibration-generating parts. Since a vibration-proof material is attached to the base of the above, a large number of considerably strong vibration-proof materials are required.Furthermore, the contamination and damage rates are extremely repetitive replacements, and only partial sound-proofing effect is expected. Could not be done. In view of the above problems, the present invention is configured such that the entire blower support frame formed by integrally forming a blower and an electric motor in a blow passage is suspended near a blowout port of an air conditioner via a vibration isolator. It is possible to dissipate the vibration of the noise generated by the blower and the electric motor to the outside of the machine by the support frame, and prevent the transmission to the machine completely, and perform various maintenance work in the air passage. Another object of the present invention is to provide an air conditioner with a noise suppression device that is also easy.
