本考案は冷蔵庫に関するもので、騒音を低減す

蔵庫騒音の主原因となつていた。しかも、通風路
の両端が開放されているため、この両端より騒音
がもれ吸音材等による吸音対策だけでは十分に騒
音を低減することができないものであつた。 Some conventional refrigerators have a ventilation path running from the bottom of the body to the back, and an electric compressor or condenser is installed in this ventilation path, and forced ventilation is performed using an electric fan. However, the fan noise of the electric fan that forcibly cools the condenser, together with the noise of the compressor, has been the main cause of refrigerator noise. Moreover, since both ends of the ventilation passage are open, noise leaks from both ends, and it is not possible to sufficiently reduce the noise by using sound absorbing materials or the like.
そこで本考案は上記点を考慮して、通風路内の
補強用の支持板を利用して消音器としての効果を

低減するものである。 Therefore, in consideration of the above points, the present invention utilizes a reinforcing support plate in the ventilation passage to produce an effect as a muffler, thereby reducing the noise of the electric fan for cooling the condenser.

された排気口１４より排気される。 An embodiment of the present invention will be described below with reference to the accompanying drawings. Reference numeral 1 denotes a main body of the refrigerator, and the interior of the refrigerator is divided into a freezer compartment 2 and a refrigerator compartment 3, each of which is provided with doors 4 and 5. Reference numeral 6 denotes an electric fan for blowing air into the refrigerator, which blows air into the freezer compartment 2 and the refrigerator compartment 3 via a duct 7. Reference numeral 8 denotes a ventilation passage constituted by a bottom plate 9 provided at the bottom of the refrigerator main body and a back plate 10 provided at the rear side. 11 is an electric fan, and 12 is a condenser, which are installed on the bottom plate 9 in the ventilation passage 8. The air sucked in by the electric fan 11 from the suction part 13 formed at the lower front of the main body 1 in the ventilation passage 8 cools the condenser 12, and is exhausted from the exhaust port 14 formed at the upper rear of the main body 1. .

The partition plate 15 is arranged in a meandering manner by double bending, and each surface 15a, 15b, 15c is parallel to each other, and a connecting portion 1 connects these surfaces.
5d and 15e are also parallel to each other.

減することができるものである。 Further, each length of each surface 15a, 15b, 15c is set to 1/4 of the wavelength of the blade sound of the electric fan 11. Further, the partition plate 15 and the back plate 10 are adhesively fixed to each other by a double-sided adhesive foam material (not shown). The back surface 18 of the main body 1 of the refrigerator, the back plate 10 and the partition plate 15 are connected to the cylinder 1 with one end open.
7, 17'. As a result, since the length of the tubes 17 and 17' with one end open is set to 1/4 of the blade noise of the electric fan 11, the wavelength of the blade noise generated by the electric fan 11 is 1/4. It acts as a resonance type muffler and reduces blade noise. Moreover, the partition plate 15
are arranged diagonally with respect to the ventilation passage 8, and the opening portions P and P' on both sides of the ventilation passage 8 are made small, so the cross-sectional area of the air passage becomes small at both ends of the one-end open tubes 17 and 17'. Since the transmission area of the blade sound is similarly small, the noise reduction effect of the cylinder with an open end is also amplified. This makes it possible to reduce the noise of the refrigerator as a whole by reducing the blade noise of the electric fan.

器により通風路の補強もはかることができる。 As is clear from the above description, the present invention forms a ventilation path that communicates from the bottom of the refrigerator to the top of the back of the refrigerator using a bottom plate provided at the bottom of the refrigerator body and a back plate provided at the back of the refrigerator main body. An electric fan is installed on the bottom part to circulate air to the condenser and ventilation path, and an open tube at one end with a length of about 1/4 of the wavelength of the electric fan's blade noise is installed between the back of the refrigerator and the back plate. Because it is a 1/4 wave muffler, the sound of the electric fan blades is reduced in the ventilation path by the action of the 1/4 wavelength muffler, reducing the amount of blade sound propagated outside the refrigerator, reducing noise and muffling it. Ventilation channels can also be reinforced by using containers.
