In the following manner motor compressor 1 is attached to object 9.At first, the first shell part 201 and the second shell part 202 are combined, so that inboard housing structure 10 is arranged between the first shell part 201 and the second shell part 202.Under this state, bolt 89A is passed the through hole 29A of the first attachment 201A and the second attachment 202A, and the far-end of bolt 89A is screwed among the tapped hole 8A at joining portion 8.And, bolt 89B is inserted the through hole 29A that passes the first attachment 201B and the second attachment 202B, and the far-end of bolt 89B is screwed among the tapped hole 8B at joining portion 8.In addition, bolt 89C is passed the through hole 29A of joint 201C and joint 202C, and the far-end of bolt 89C is screwed in the unshowned nut.This is bonded to each other the first shell part 201 and the second shell part 202, thereby motor compressor 1 is attached to object 9.
As shown in Figure 2, outside housing structure 20 can hold inboard housing structure 10.Particularly, the internal face 20B that is formed by the first shell part 201 and the second shell part 202 and the outer wall 10C close contact of inboard housing structure 10.Inboard housing structure 10 thereby by 20 supportings of outside housing structure.Bolt 89A, 89B, 89C are the example according to securing means of the present invention.In the situation that inboard housing structure 10 is contained in the housing structure 20 of the outside, suction member 50 and discharge member 60 extend out to the outside from the corresponding opposite end of outside housing structure 20.Suck member 50 and discharge member 60 and be contactless state with respect to outside housing structure 20.
Use the air regulator of above-mentioned motor compressor 1 in the following manner the temperature in the compartment to be regulated.
With reference to Fig. 1, reduce in order to make the temperature in the compartment, selector valve 91 allow between discharge tubes 96 and the pipe 97 be communicated with and suction pipe 95 with manage being communicated with between 99.This makes the compressed 3(of mechanism see Fig. 2) refrigeration agent that is compressed into high-temperature high-pressure state flows along direction D1.Refrigeration agent thereby in extraneous air heat exchanger 92, heat is released into air and liquefaction.Then, expansion valve 93 reduces the pressure of refrigeration agent.Subsequently, refrigeration agent absorbs heat and the evaporation from the air in the compartment in compartment heat exchanger 94.This makes the air cooling in the compartment.Then refrigeration agent is back to motor compressor 1 via pipe 99, selector valve 91 and suction pipe 95.
On the contrary, raise in order to make the temperature in the compartment, switching valve 91 allow between discharge tubes 96 and the pipe 99 be communicated with and suction pipe 95 with manage being communicated with between 97.This refrigeration agent that makes compressed mechanism 3 be compressed into high-temperature high-pressure state flows along the D2 direction.Refrigeration agent thereby in compartment heat exchanger 92, heat is released into air and liquefaction in the compartment.This is with the air heating in the compartment.Then, expansion valve 93 reduces the pressure of refrigeration agent.Subsequently, refrigeration agent absorbs heat and the evaporation of the air that comes from the outside in extraneous air heat exchanger 92.Then refrigeration agent is back to motor compressor 1 via pipe 97, selector valve 91 and suction pipe 95.
In the motor compressor 1 of the first mode of execution, compressing mechanism 3 and motor mechanism 5 are with the very high inner shell 10 that is rigidly fixed to.Therefore, transmit between inboard housing structure 10 and object 9 if can not prevent vibration or noise, the vibration and the noise that then produce in compressing mechanism 3 and the motor mechanism 5 are not passed to object 9 via inboard housing structure 10 and outside housing structure 20 with substantially weakening.This reduces the comfort level in the compartment.In addition, when allowing the heat transmission occurs between inboard housing structure 10 and object 9, the heat of the high-temperature high-pressure refrigerant of compressed mechanism 3 compressions is transferred to object 9.
Yet in the motor compressor 1 of the first mode of execution, compressing mechanism 3 and motor mechanism 5 are accommodated in the inner in the side body member 10 with the state of sealing.The outside housing structure 20 that is formed by absorbing and adiabatic plastics combines.Particularly, the first shell part 201 and the second shell part 202 are combined.Thus, outside housing structure 20 holds and supports inboard housing structure 10.Therefore, because inboard housing structure 10 is by outside housing structure 20 supporting of absorbing, so the vibration that is passed to outside housing structure 20 from inboard housing structure 10 reduces.And, suck member 50 and under with respect to outside housing structure 20 non-contacting states, be fixed to inboard housing structure 10 with discharge member 60.This prevented in compressing mechanism 3 and the motor mechanism 5 vibration that produces and noise outside side body member 20 with suck member 50 and discharge transmission between the member 60.Therefore, prevented that the noise and the vibration that produce in compressing mechanism 3 and the motor mechanism 5 are passed to object 9 from inboard housing structure 10.
In addition, because housing structure 20 thermal insulation in the outside are passed to outside housing structure 20 and object 9 so outside housing structure 20 prevents the heat of the high-temperature high-pressure refrigerant of compressed mechanism 3 compressions from inboard housing structure 10.Thereby, when refrigeration agent is inhaled into or discharges, keep the heat in the refrigeration agent can not reduce.Therefore, though when motor compressor 1 by along direction D2(as shown in Figure 1) transmit that refrigeration agent be used as heat pump so that when the compartment warmed, the temperature of mobile refrigeration agent also can remain on very high level in compartment heat exchanger 94.This make compartment heat exchanger 94 can be more effectively air releasing heat in the compartment, thereby give full play to heating performance.Therefore, the motor compressor 1 of the first mode of execution prevents that vibration and noise are passed to the outside, and can give full play to heating performance when being used as heat pump.
As already described, bolt 89A passes the first attachment 201A, the second attachment 202A and tapped hole 8A(object 9).Bolt 89B is inserted through the first attachment 201B, the second attachment 202B and tapped hole 8B(object 9).Bolt 89C is screwed among connecting part 201C, the 202C.Therefore, so that outside housing structure 20 can hold inboard housing structure 10 and be fixed to object 9.In other words, inboard housing structure 10 is arranged in the housing structure 20 of the outside and outside housing structure 20 is fixed to object 9 and carry out simultaneously.This has just simplified the assembling of motor compressor 1.
Outside housing structure 20 is made of the first shell part 201 with the first attachment 201A, 201B and the second shell part 202 with the second attachment 202A, 202B.This configuration has been simplified outside housing structure 20.
Because outside housing structure 20 be tubulose and very simple in shape, so reduced the cost of manufacturing motor compressor 1.And, easily inboard housing structure 10 is arranged in the housing structure 20 of the outside.This has just simplified the assembling of motor compressor 1.
Because the first shell part 201 and the second shell part 202 are formed by plastics, so 20 easy absorbing and the thermal insulation of outside housing structure.This has guaranteed effect of the present invention with the reliability that strengthens.
Attachment 29 each free metal enhancing 29B of section strengthen.Therefore, even when applying power to the outside housing structure 20 that is attached to object 9, prevent that also attachment 29 is damaged.
(the second mode of execution)
As shown in Figure 4, the motor compressor of the second mode of execution of the present invention has adopted the outside housing structure 20 of outside housing structure 21 rather than the first mode of execution.For the second mode of execution and the same or analogous parts of corresponding parts the first mode of execution, omitted detailed description herein.
As shown in Figure 4, outside housing structure 21 is made of the first shell part 211 and the second shell part 212.The first shell part 211 and the second shell part 212 are separately by being that each end in the opposite end of corresponding first shell part 201 of the first mode of execution and the second shell part 202 adds substantially that semicircular wall section 213 forms.In each wall section 213, be formed with otch 214, interfere with sucking member 50 or discharge member 60 avoiding.By with the first shell part 211 and the second shell part 212 combinations with one another, outside housing structure 21 forms container-like.
Because the motor compressor of the second mode of execution allows the outside housing structure 21 of container shapes integrally to hold inboard housing structure 10, so realized reliably absorbing performance and heat-insulating property.
(the 3rd mode of execution)
As shown in Figure 5, the motor compressor of the 3rd mode of execution of the present invention has adopted the outside housing structure 20 of outside housing structure 22 rather than the first mode of execution.For the 3rd mode of execution and the same or analogous parts of corresponding parts the first mode of execution, omitted detailed description herein.
With reference to Fig. 5, outside housing structure 22 comprises shell part 221,222 and be used for articulated section 223 that shell part 221,222 is bonded to each other.Articulated section 223 forms with shell part 221,222.
Shell part 221 is configured as similar to the first shell part 201 of the first mode of execution but does not have connecting part 201C.Equally, shell part 222 is configured as similar to the second shell part 202 but does not include connecting part 202C.Articulated section 223 is connected the upside of shell part 221 with the upside of shell part 222.The upside of shell part 221 extends at the longitudinal direction of a side relative with attachment 201A, 201B along shell part 221.The upside of shell part 222 extends at the longitudinal direction of a side relative with attachment 202A, 202B along shell part 222.Thereby articulated section 223 is out of shape so that shell part 221 contacts with each other with shell part 222.Thereby, formed the outside housing structure 22 of tubulose.
The motor compressor of the 3rd mode of execution has operation and the advantage identical with the motor compressor 1 of the first mode of execution.In addition, owing to saved connecting part 201C, 202C and bolt 89C, so reduced the quantity of essential parts and made it possible to assemble simply motor compressor.
(the 4th mode of execution)
As shown in Figure 6, use the outside housing structure 20 of outside housing structure 23 rather than the first mode of execution according to the motor compressor 2 of the 4th mode of execution of the present invention, and comprised the intermediate member 31,32 that is arranged between inboard housing structure 10 and the outside housing structure 23.For the 4th mode of execution and the same or analogous parts of corresponding parts the first mode of execution, omitted detailed description.
With reference to Fig. 6, outside housing structure 23 has a pair of close contact section 231 and interval parts 232.Close contact section 231 is arranged on the corresponding opposite end place of outside housing structure 23, and the outer wall 10C close contact of maintenance and inboard housing structure 10.Interval parts 232 between the close contact section 231 and and the outer wall 10C of inboard housing structure 10 between spaced apart.Form the gap between this outer wall 10C that is arranged in interval parts 232 and inboard housing structure 10.
Intermediate member 31,32 is arranged in this gap.Intermediate member 31 is formed by the material different from the material of intermediate member 32.Particularly, intermediate member 31 is formed by the absorbing material, such as rubber, elastomer, plastics, fiber reinforced plastic or silicon gel.Especially, each intermediate member 31 is formed by ring-shaped rubber body (it is O shape ring).Intermediate member 31 is arranged on place, a corresponding end in two opposite ends of interval parts 232 separately.Intermediate member 31 with by compression or the state of distortion be installed in the gap between the outer wall 10C of interval parts 232 and inboard housing structure 10.On the contrary, intermediate member 32 is formed by thermoinsulation material, as includes fiber assembly, foamed material, cellulose fiber or the Vacuum thermal insulating material of glass yarn.Especially, in the 4th mode of execution, the thick laminar body that intermediate member 32 is made by glass yarn form.Intermediate member 32 twines around the outer wall 10C of inboard housing structure 10, with the gap between the outer wall 10C that fills interval parts 232 and inboard housing structure 10.
In the motor compressor 2 of the 4th mode of execution, each intermediate member 31 absorbs vibration.This prevents effectively that further the noise and the vibration that produce in compressing mechanism 3 and the motor mechanism 5 are passed to object 9 from inboard housing structure 10.In addition, because intermediate member 32 thermal insulation are released into object 9 so further effectively prevent the heat of the high-temperature high-pressure refrigerant of compressed mechanism 3 compressions from inboard housing structure 10.
The first mode of execution to the four mode of executions can be modified as following form.
In the 4th mode of execution, close contact section 231 can be saved from outside housing structure 23.In this case, outside housing structure 23 is configured to hold inboard housing structure 10 across intermediate member 31,32.Alternatively, in the 4th mode of execution, can replace intermediate member 31,32 with absorbing and adiabatic integral type intermediate member.In addition, only absorbing or only adiabatic of this intermediate member.
Compressing mechanism 3 can adopt any suitable compression method except the eddy type method, such as reciprocating type compression method or blade type compression method.
