Technical field
The utility model belongs to the baffler of compressor field, especially a kind of baffler that is shaped on counter balance pocket.
Background technique
The refrigeration household electric appliance are except needs have good refrigeration, and low power consuming, low noise also are the targets that people pursue.The noise of refrigeration household electric appliance is the vibration noise that compressor is produced in being interrupted process of refrigerastion mainly from the operation of compressor, and this periodic vibration noise brings certain worry for people's daily life.In order to reduce the noise of compressor, on compressor cylinder cover, be fixed with baffler at present, this baffler is generally by muffler cavity, cavity capping and constituting interior connecting tube within it is installed, be shaped on intakeport on the muffler cavity, be shaped on the air outlet in the cavity capping, interior connecting tube, two ends connected intakeport and air outlet respectively, and the air outlet of this baffler connects the intakeport of valve plate on the compressor casing by pipeline.Though this muffler structure can reduce the noise of compressor to a certain extent, but still there are the following problems: (1). in the compressor piston cylinder breathing process, be easy to generate negative pressure in the muffler cavity, cause baffler to move to the compressor housing direction, or even collision, reduced compressor stability thus significantly; (2). the negative pressure in the muffler cavity may make the lubricant oil that oil leaking hole dripped of muffler cavity bottom surface produce suck-back, is unfavorable for that lubricant oil discharges in baffler; (3). whole cavity noise reduction capability is relatively poor, can not satisfy the needs of technical development.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of baffler that is shaped on counter balance pocket is provided, and this baffler overall structure is simple, design science is reasonable, can effectively reduce the negative pressure in the muffler cavity, reduce the compressor overall noise, improve the stability of compressor.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of baffler that is shaped on counter balance pocket, by muffler cavity, cavity capping and interior connecting tube constitute, cavity capping sealing is packed on the muffler cavity, be installed on interior connecting tube by muffler cavity and cavity capping and install in the back cavity that forms, muffler cavity one side is shaped on intakeport, be shaped on oil leaking hole on the muffler cavity bottom surface, be shaped on the air outlet in the cavity capping, interior connecting tube one, end was communicated with intakeport, the other end is communicated with the air outlet, wherein be separated out a counter balance pocket by dividing plate in the muffler cavity of muffler cavity intakeport opposite side, the lower shoe in this counter balance pocket is shaped on equalizing orifice, and this counter balance pocket is connected with muffler cavity.
And described interior connecting tube is installed on by muffler cavity and cavity capping by the clamp that is shaped on it and installs in the back cavity that forms.
And, described in connecting tube middle part radially be built-in with filter screen, interior connecting tube the top radial symmetric be shaped on two bloops.
Advantage of the present utility model and beneficial effect are:
1. the baffler that originally is shaped on counter balance pocket is separated out a counter balance pocket by dividing plate in the muffler cavity of muffler cavity intakeport opposite side, lower shoe in this counter balance pocket is shaped on equalizing orifice, this counter balance pocket is connected with muffler cavity, when the compressor piston cylinder is air-breathing, the negative pressure that produces in the muffler cavity can be carried out balance by the gas that equalizing orifice sucks, reduce the inside and outside pressure difference of rubber coupler that connects compressor suction duct and baffler inlet, thereby reduce the vibration of compressor movement, strengthen the stability of compressor, keep good dynamic balancing.
2. the interior connecting tube of baffler that originally is shaped on counter balance pocket is installed on by muffler cavity and cavity capping by the clamp that is shaped on it and installs in the back cavity that forms, clamp is divided into a resonant cavity with whole cavity, an expansion chamber, can effectively reduce because the noise that compressor air suction valve block switch produces improves noise reduction capability.
3. the middle part of interior connecting tube of baffler that originally is shaped on counter balance pocket radially is built-in with filter screen, has ensured the turbidity test that suck gas, the working life of improving compressor.
4. the utility model overall structure is simple, and design science is reasonable, can effectively reduce the negative pressure in the muffler cavity, reduces the compressor overall noise, improves the stability of compressor, is the higher baffler that is shaped on counter balance pocket of a kind of novelty.

Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of baffler that is shaped on counter balance pocket, by muffler cavity 2, cavity capping 1 and interior connecting tube 10 constitute, cavity capping sealing is packed in and forms a whole chamber on the muffler cavity, connecting tube is made of with right semicanal 20 left semicanal 21 in whole, it is fastened by the filter screen cartridge 12 interior clamps 14 that the middle part radially is shaped on, be installed on by muffler cavity and cavity capping sealing connecting tube in whole and install in the back whole cavity that forms by the clamp 16 that is shaped on it, this dividing plate is divided into a resonant cavity 17 with whole chamber, an expansion chamber 15, muffler cavity one side is shaped on intakeport 6, corresponding with intakeport is expansion chamber, be shaped on drainage tube 5 on the muffler cavity bottom surface, be shaped on oil leaking hole 9 on the muffler cavity bottom surface in this drainage tube, the position of present embodiment drainage tube shown in the drawings is built in the bottom surface of resonant cavity, be shaped on air outlet 3 in the cavity capping, short tube 4 side end that make on by the cavity capping this air outlet, interior connecting tube one, end was communicated with intakeport, the other end is communicated with the air outlet, the filter screen cartridge at middle part is built-in with filter screen 13 in interior connecting tube, interior connecting tube, upper resonance chamber one side radial symmetric was shaped on two bloops 11, innovative point of the present utility model is: be separated out a counter balance pocket 18 by dividing plate 19 in the muffler cavity of muffler cavity intakeport opposite side, lower shoe 7 in this counter balance pocket is shaped on equalizing orifice 8, and this counter balance pocket is connected with muffler cavity.
