Description
Technical field
The utility model relates to the rotary compressor of equipment such as being used for air-conditioning, refrigerator, dehumidifying, specifically refers to the Horizontai rotary compressor of a kind of motor and compressor pump lateral arrangement.
Background technique
Vertical rotating formula compressor is because horizontal occupation area is little, and force-bearing situation is good, and characteristics such as lubricated realization have easily accounted for absolute dominant position at room air conditioner and dehumidifier field.But when being used for the occasion that is restricted in the space of Vertical direction, as be used for aspects such as car air conditioner, refrigerator refrigerator, require the compressor of horizontal design.And because the horizontal compressor center of gravity is low, noise is also little.But the lubrication oil supply problem of horizontal compressor is a difficult problem.
Japanese patent laid-open 5-280485 proposes a kind of horizontal type rotary compressor, adopts the mode of vane pump fuel feeding, as shown in Figure 7.Side at the length direction of seal casinghousing 1 ', the built-in motor 2 ' that constitutes by rotor 22 ' with live axle 4 ' and stator 21 ', built-in at the length direction opposite side by having relief opening 35 ', the compression key element 3 ' that right cylinder cap 32 ' and left cylinder cap 33 ' and cylinder 31 ' constitute, live axle 4 ' one end is communicated with oil sump 1c ' in the housing 1 ', have fuel feeding through hole 42 ' on the bent axle of motor 2 ', the open communication of its opening portion 42d ' and air aspiration cavity 51 ', and be provided with centrifugal pump key element 5 ', this centrifugal pump key element 5 ' have some can be from the path 52 ' of air aspiration cavity 51 ' radius vector to foreign side's exhaust.As fully visible, this compressor designs centrifugal pump by the right part at rotor, gas in the fuel feeding through hole 42 ' on the suction bent axle, cause pressure in the through hole to be lower than pressure in the housing 1 ', thereby make lubricant oil be drawn into the bent axle through hole 42 ' from oil ground 1c ' under differential pressure action, be transported to each lubricant housings via each oil supply hole again under action of centrifugal force, unnecessary oil is by bent axle through hole 42 ', finally discharge, import the oil sump 1c ' of enclosure interior below by drain passageway 52 '.
There are three problems in this design: 1, because the blade 54 ' of the centrifugal pump 5 ' of rotor 22 ' front end is a prismatic blade, only depend on action of centrifugal force that the gas in the bent axle through hole 42 ' is discharged, and the gas in the bent axle through hole 42 ' rotates with rotor 22 ', bent axle through hole 42 ' is relative with centrifugal pump static, the pumping action of pump is weakened, and therefore the pressure reduction that forms is limited; 2, after lubricant oil arrives bent axle through hole 42 ', only depend on centrifugal force to arrive each lubricant housings through corresponding oil supply hole; 3, has only one road lubrication channel.
Summary of the invention
The purpose of this utility model is that design a kind ofly has the two-way lubrication channel, can guarantee the Horizontai rotary compressor of enough lubrication oil supply amounts, and makes every effort to simple in structure, and parts are few, and cost is low, reliable operation.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of Horizontai rotary compressor, the closed shell 1 that only communicates that comprises a lateral arrangement by suction, exhaust duct and the external world, be located at the motor section 2 on enclosure interior right side and the press part 3 in left side, and the lubricating oil sump 44 of enclosure interior below; Described motor section is made of stator 21 and rotor 22, and described press part is made of piston 31, cylinder 32, left and right cylinder cap 34,33 and bent axle 50; Described bent axle left part is provided with fuel supply line 43, this fuel supply line one end stretches in the described oil sump, the axle head chamber H3 that the other end surrounds in the bent axle left part by baffler 42 communicates with the oil supply gallery 48 on the bent axle, bent axle is provided with the radially oil supply hole 51 that some whiles communicate with this oil supply gallery 48 and each need lubricating component, it is characterized in that on described rotor that end near right cylinder cap one side is provided with one can be to radially or the rotor pump P of axial exhaust, and between right cylinder cap 33, rotor 22, motor shaft and rotor pump P formation one suction chamber H1; On left and right cylinder cap, be provided with oil groove 45,46, oil groove 45 left ends on the cylinder cap of a left side are connected with described axle head chamber H3, its right-hand member be connected with the inner chamber H2 that bent axle 50 constitutes by piston 31, left and right cylinder cap 34,33, oil groove 46 left ends on the right cylinder cap are connected with this inner chamber H2, its right-hand member is connected with the suction chamber H1 of rotor pump, oil supply gallery 48 on described fuel supply line 43, the bent axle, each oil groove 45,46, described axle head chamber H3, inner chamber H2 and suction chamber H1 on oil supply hole 51, rotor pump P and the left and right cylinder cap radially constitute a complete oil supply system.
The beneficial effects of the utility model are: because lubricant oil is under the acting in conjunction of pressure reduction and centrifugal force, be lubricated by two passages each position compressor, even also reliable fuel feeding when low-speed running, simultaneously because the right cylinder cap 33 of formation suction chamber H1 is static with respect to pump P, make the suction effect of pump P strengthen greatly, thereby guaranteed fully reliable fuel delivery in the compressor operation, guaranteed the reliability of compressor.The utility model is simple in structure, and parts are few, and cost is low, good reliability.
