Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of freezer compressor housing structure is provided, this housing structure can effectively cushion pressurized gas, reduce air pulsing, reduce the freezer compressor overall noise, reduced noise pollution, improve compressor performance environment.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of freezer compressor housing structure, comprise cylinder block base, valve plate component and cylinder cap, the top of this cylinder block base is shaped on valve plate connecting base, crankshaft hole, static pressure chamber and hyperbaric chamber respectively, be shaped on piston hole on the end face of valve plate connecting base, valve plate connecting base, valve plate component and cylinder cap is coaxial installs, the valve plate component is made of valve plate, suction valve chip, exhaust valve plate and exhaust valve plate snubber, the valve plate of valve plate connecting base one side is provided with suction valve chip, the valve plate of cylinder cap one side is provided with exhaust valve plate and exhaust valve plate snubber, wherein
(1) the static pressure chamber is that blind hole also is communicated with cylinder cap by the static pressure chamber vent on the valve plate component;
(2) chamber of hyperbaric chamber lid is the hemispherical cavity lid;
(3) exhaust valve plate of valve plate is opened to the direction in static pressure chamber.
And described static pressure chamber and hyperbaric chamber are prepared in the both sides of valve plate connecting base.
Advantage of the present invention and beneficial effect are:
1, the static pressure chamber on the cylinder block base of this freezer compressor housing structure is that blind hole is communicated with cylinder cap by the static pressure chamber vent on the valve block, played the effect that increases the cylinder cap volume, increased the high pressure buffer gas space, pulsation to gas pressure plays buffer function, thereby has played the effect that reduces noise.
2, the chamber of the hyperbaric chamber of this freezer compressor housing structure lid under the situation that does not increase the freezer compressor volume, has increased the volume of hyperbaric chamber for hemispherical cavity covers, and the pulsation of gas pressure is played buffer function, and then reduced noise.
3, the exhaust valve plate of the valve plate of this freezer compressor housing structure is opened to the direction in static pressure chamber, makes to be discharged to by the valve plate relief opening that the pressurized gas of cylinder cap are most advanced goes into the static pressure chamber, and the buffer gas pressure pulsation effectively reduces noise.
4, the static pressure chamber of this freezer compressor housing structure and hyperbaric chamber are prepared in the both sides of valve plate connecting base, help the integrally-built center of gravity of compressor and keep balance, the pressurized gas that flow to above-mentioned two chambeies are flowed to keep balance, thereby reduce compressor because vibration and the noise that the structure imbalance causes, the noise of the compressor 1-3 decibel that can descend, the coefficient of performance can improve 1%.
5 housing structures of the present invention are simple, and design science is reasonable, can effectively cushion pressurized gas, reduce air pulsing, reduce the freezer compressor overall noise, reduced the noise pollution to environment, improve compressor performance.

Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of freezer compressor housing structure, comprise cylinder block base 3, valve plate component and cylinder cap 2 constitute, the top of this cylinder block base is shaped on valve plate connecting base 7 respectively, crankshaft hole 8, static pressure chamber 1 and hyperbaric chamber 5, be shaped on piston hole 10 on the end face of valve plate connecting base, the valve plate connecting base, valve plate component and cylinder cap are coaxial to install, the valve plate component is by valve plate 6, suction valve chip 18, exhaust valve plate 17 and exhaust valve plate snubber 13 constitute, the valve plate of valve plate connecting base one side is provided with suction valve chip, and the valve plate of cylinder cap one side is provided with exhaust valve plate and exhaust valve plate snubber.
Innovative point of the present invention is: made static pressure chamber, (1) cylinder block base top is a blind hole, and the suction port 9 of this blind hole is communicated with cylinder cap by the static pressure chamber vent 12 on the valve plate component; (2) chamber of the made hyperbaric chamber in cylinder block base top lid 4 covers for hemispherical cavity; (3) exhaust valve plate of valve plate is opened to the direction in static pressure chamber.Static pressure of the present invention chamber and hyperbaric chamber are prepared in the both sides of valve plate connecting base, so the noise of the compressor 1-3 decibel that can descend, and the coefficient of performance can improve 1%.
This cylinder body structure of compressor working principle:
