Abstract
In a compressor, an inverter control device that performs an inverter control on an electric motor is integrally provided on a body portion of a container which houses a compression mechanism and the electric motor which are axially arranged in a line. The inverter control device is connected to the electric motor to shorten the distance of wiring from the inverter device to the motor to allow the reduction in weight, the reduction in a space to be required for the installation, and the reduction in the amount of noise.
Description
The present disclosure relates to subject matter contained in priority Japanese Patent Application No. 2001-174430, filed on Jun. 8, 2001, the contents of which is herein expressly incorporated by reference in its entirety.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a compressor with a built-in electric motor which is suitable to be mounted on a mobile structure such as a motor vehicle. The invention also relates to a mobile structure having such a compressor.
2. Description of Related Art
In a vehicle driven only by an engine, a compressor driven by the engine has been used for air-conditioning the vehicle compartment with the compressor being mounted alongside of the engine.
Hybrid vehicles having both an engine and an electric motor and traveling by use of one of them according to conditions have been practically used for going on public roads. Air-conditioning of the vehicle compartment of this hybrid vehicle is made by a refrigerating compressor driven by the engine in the same manner as conventional engine-driven vehicles, which is mounted alongside of the engine.
It is proposed that the engines of hybrid vehicles should be shut off while they are temporarily stationary at a place such as a traffic light in order to reduce effects of the engine upon the environment. When the proposal is followed with a vehicle where a compressor driven by the engine is used, air-conditioning stops each time when the vehicle stops, causing problem for the driver and passengers in the compartment in summer and winter seasons, and especially in regions with extremely cold or hot climate.
For solving such a problem, there is an idea of adopting a compressor
153
to be driven by an electric motor, especially a compressor to be used for air-conditioning in a building as shown in FIG.
2
. The compressor with a built-in electric motor is housed in a container
152
made of iron, together with a compression mechanism
150
and an electric motor
151
. In the hybrid vehicle, furthermore, the arrangement of devices in an engine room is based on that of the conventional motor vehicle. Thus, there is no space or location for installing the conventional compressor with the built-in electric motor for air-conditioning in the building in the engine room.
What is worse, the conventional compressor with the built-in electric motor has large axial dimensions. That is, a discharge port
154
, a suction port
155
, inner and outer electric connection parts
156
, and a mounting leg portion
157
are longitudinally extended from both ends of the container
152
. Such a complicated construction of the compressor is hardly incorporated in an electric-powered vehicle which has been only realized in a small-sized vehicle.
Simultaneously, the conventional compressor with the built-in electric motor is made of iron, so that the total weight thereof is about 9 kg or more. Thus, it becomes a problem in realizing the high speed and the energy saving because of the increase in driving load when it is mounted on the mobile structure.
It becomes urgent business to provide a small-sized and lightweight compressor with a built-in electric motor now in a tendency of planning an electric operation of various kinds of load by using a working voltage of 42 volts in a gasoline-powered vehicle, a hybrid vehicle, or an electric-powered vehicle. For this reason, it is considered to use a compressor
159
with a built-in electric motor having a container
158
made of aluminum as shown in FIG.
3
.
An electric motor
160
is operated under the inverter control so as to correspond to various kinds of conditions. An inverter control device
161
responsible for the inverter control and the compressor
159
are mounted on an appropriate fixing member in the vicinity thereof. As shown in
FIG. 3
, when the compressor
159
is fixed on the engine
162
, the inverter control device
161
is fixed and supported on another fixing member
163
to avoid the high temperature engine
162
.
However, even though the working voltage increases from 12 volts to 42 volts, it is still a low voltage compared with a working voltage of about 100 volts to 200 volts which is used for an air conditioning intended for home use. Consequently, if it tends to obtain the same output as that of about 100 volts to 200 volts, there is a need to feed a large current. For addressing such a requirement, a plurality of wirings for supplying the electric power between the inverter control device
161
and a terminal
164
provided on the container
158
, a plurality of wirings for supplying the electric power between the terminal
164
and the electric motor
160
, and an electrode are increased in size, thereby increasing the weight of the compressor. Furthermore, the generation of noise may be increased to influence on the peripheral electronic devices. In each of the cases, it will be a problem for mounting on the vehicle. What is worse, the increase in size leads to the increase in cost.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a compressor with a built-in electric motor suitable for a mobile structure without causing the increase in weight, cost, and noise by shortening the wiring distance from the inverter device to the electric motor. Another object of the invention is to provide a mobile structure having such a compressor with a built-in electric motor.
To achieve the above objects, a first aspect of the present invention is to provide a compressor with a built-in electric motor, including: a compression mechanism; the built-in electric motor for driving the compression mechanism; and a container for housing the compression mechanism and the built-in electric motor, wherein an inverter control device that performs an inverter control on the built-in electric motor is integrally provided on a part of the container and is connected to the electric motor.
According to such a configuration, since the inverter control device is provided on a part of the container, there is no need to provide comparatively long external wirings for connecting between the inverter control device and the container when the built-in electric motor housed in the container together with the compression mechanism is subjected to an inverter control by the inverter control device to operate the compression mechanism under various conditions. In addition, a single terminal can be shared between the connections for the inverter control device and the electric motor, so that one of the terminals conventionally used is removed. Accordingly, when it is mounted on the vehicle and used at a low voltage of 12 volts or 42 volts where the number of wirings and the size of electrode are increased, the wiring distance is shortened due to the elimination of external wirings, and the decrease in weight of the compressor is achieved because of reducing one of the terminals. Furthermore, the space for mounting the compressor including the inverter control device is reduced, so that the compressor is more easily mounted on the vehicle. Besides, there is an advantage in driving load and also in cost reduction.
A second aspect of the invention is to provide a compressor with a built-in electric motor, wherein an inverter control device that performs an inverter control on the built-in electric motor is integrally provided on a body of the container in which the compression mechanism and the electric motor are housed such that they are axially arranged in a line, and the inverter control device is connected to the electric motor.
According to such a configuration, the electric connection part of the inverter control device and the electric connection part of the electric motor housed in the body portion of the container become closer to each other. Thus, the length of the wiring in the container id reduced, and the weight and cost of the compressor depending on the wiring is reduced. Furthermore, the compressor of the present embodiment is easily installed in a restricted space of the vehicle since there is no need to increase the axial dimension of the container.
While novel features of the invention are set forth in the preceding, the invention, both as to organization and content, can be further understood and appreciated, along with other objects and features thereof, from the following detailed description and examples when taken in conjunction with the attached drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereinafter, a compressor with a built-in electric motor as one of preferred embodiments of the present invention and a mobile structure having such a compressor will be described with reference to the accompanying drawings for facilitating the understanding of the invention.
In this embodiment, the compressor is a scroll type compressor with a built-in electric motor to be mounted on an engine of a hybrid vehicle. However, the invention is not limited to such a type of compressor. The present invention is also applicable to any compressor for air-conditioning of the interior of a room in addition to the vehicle compartment of a typical mobile structure such as a motor vehicle, exerting the advantages of weight reduction and miniaturization. According to the invention, various kinds of compression mechanisms, for example rotary and reciprocation type compression mechanisms, may be used. Furthermore, any vertical type compressor may be used.
As shown in
FIG. 1
, a hybrid vehicle
27
includes a gasoline-powered engine
2
and a motor
3
to be driven by the supply of power from a battery
1
. The battery
1
is a rechargeable battery. While the vehicle runs using the engine
2
, the battery
1
is charged. While the battery
1
has a sufficient charged capacity, the motor
3
is controlled to receive the supply of power for driving the vehicle with the motor
3
to restrict the discharge of exhaust gas to a minimum. When the vehicle is running with the engine
2
, the engine
2
is controlled such that the engine
2
is stopped while the vehicle is temporally stopped, for example at a traffic light.
In this embodiment, as shown in
FIG. 1
, a compressor
11
driven by a built-in electric motor
13
is used for an air-conditioning of the vehicle compartment of the hybrid vehicle. The compressor
11
is constructed to receive the supply of power from the battery
1
to keep the air-conditioning of the vehicle compartment even though the vehicle running with the engine
2
is temporally stopped at a traffic light or the like and the engine
2
is stopped.
As shown in
FIG. 1
, a scroll type compression mechanism
10
and the electric motor
13
having a driving shaft
14
to drive the compression mechanism
10
are housed in a container
12
, to constitute the compressor
11
. Under the control of an inverter control device
101
, the electric motor
13
is operated by the supply of power through a terminal
15
provided as inner and exterior electric connection parts of the container
12
to actuate the compressor
10
. The compressor
10
inspires a refrigerant after passing through a refrigeration cycle via a suction port
16
of the container
12
to compress the refrigerant. Then, the compressed refrigerant is discharged into the inside of the container
12
to cool the electric motor
13
, followed by discharging the refrigerant to an external pipe via a discharge port
17
of the container
12
to supply the refrigerant to the refrigeration cycle. Subsequently, these steps are repeated. The terminal
15
includes a body part
15
a,
an inner terminal
15
b,
and an external terminal
15
c.
In addition, the terminal
15
has a sealing structure. That is, the inner and external terminals
15
b,
15
c
are connected to each other and pass through the body part
15
a,
where the passing-through portion of the body part
15
a
is sealed with a sealant such as a glass sealant.
In the container
12
, there is oil
18
being stored. The oil is inhaled by a pump
19
driven by the driving shaft
14
. The oil is then supplied to a main bearing
21
of a main axial part
14
b
of the driving shaft
14
on the side of the compression mechanism
10
, a bearing
22
of a coupling portion between the main axial part
14
b
and the compression mechanism
10
, and a sliding portion of the compression mechanism
10
to make smooth. After lubricating the bearings and the sliding portion, the oil
18
seeps through each lubricating object by means of a supply pressure and then returns to the inside of the container
12
, followed by repeating such a lubricating process. By means of the action of a compatibility, a part of the refrigerant to be discharged into the container
12
brings the oil
18
stored in an oil storage portion
24
in the container
12
into a part such as a sub-bearing
23
which cannot be supplied with oil
18
by the pump
19
, lubricating the sub-bearing
23
or the like. The sub-bearing
23
is responsible for bearing a sub-axial part
14
a
on the side of the driving shaft
14
opposite to the compression mechanism
10
. Consequently, the compressor
11
having the built-in electric motor of the present embodiment satisfies the requirements for maintenance free.
In the present embodiment, as shown in
FIG. 1
, an electrical connection between the inverter control device
101
and the container
12
is simplified. In this embodiment, that is, the inverter control device
101
is integrally mounted on a part of the container
12
. The inverter control device
101
is electrically connected by an internal wiring
102
to the electric motor
13
by making a connection between the terminal
15
and a connection terminal
104
on the end of a coil
13
b
provided as a part of a stator
13
a
of the electric motor
13
. The electric motor
13
, which is housed in the container
12
together with the compression mechanism
10
, is operated by being subjected to an inverter control by means of the inverter control device
101
, allowing the compression mechanism
10
to work under the various kinds of conditions. In brief, a plurality of comparatively long external wirings, as shown in
FIGS. 2 and 3
, which connect between the inverter control device
101
and the container
12
, are not required since the inverter control device
101
is mounted on a part of the container
12
. In the conventional compressor, by the way, each of the inverter control unit and the electric motor requires its own terminal. In this embodiment, however, the terminal
15
can be shared for connecting between the inverter control unit
101
and the electric motor
13
. The present embodiment is able to delete one of the terminals
15
, which are conventionally required for both the electric motor and the inverter control device. That is, even though the dimensions of the wiring parts and the electrodes are increased as the compressor is installed in the vehicle
27
and is then used at a low voltage of 12 volts or 42 volts, the wiring distance is significantly shortened as much as a unnecessary part of the external wiring and one of the terminals are removed. Thus, the weight of the compressor is smaller than that of the conventional one. In addition, an installation space including the space for installing the inverter control device
101
is reduced, so that the compressor is easily mounted on the vehicle
27
. There is also an advantage in driving load and also in cost reduction.
The inverter control device
101
is integrally mounted on a body portion
12
a
of the container
12
in which the compression mechanism
10
and the electric motor
13
are arranged in a line in the axial direction. Thus, comparing with the conventional one, the distance between an electric connection part of the inverter control device
101
and an electric connection part of the electric motor
13
housed in the body portion
12
a
of the container
12
(i.e., in the embodiment shown in the figure, the distance between the terminal
15
and the connection terminal
104
) is shortened because of the integration of the inverter control device
101
with the body portion
12
a.
Thus, the length of wiring by the internal wiring
102
in the container
12
is also shortened, and the weight and cost of the compressor depending on the wiring is reduced. Furthermore, the compressor of the present embodiment is easily installed in a restricted space of the vehicle
27
or the like since there is no increase in the axial dimension of the container
12
even though the inverter control device
101
is provided thereon.
As shown in
FIG. 1
, the inverter control device
101
includes an electrode part
105
and an inverter part
106
which are electrically connected to each other. The inverter part
106
, for example, is constructed of an inverter chip provided as a multi-layered circuit. In this case, however, a concrete configuration of such a circuit is no object in particular. The electrode part
105
is opposed to a high pressure portion
107
of the container
12
, while the inverter part
106
is opposed to a low pressure portion
108
of the container
12
. That is, the electrode part
105
and the inverter part
106
are separately placed in compartments (i.e., the high pressure portion
107
and the low pressure portion
108
) which are formed in the container
12
so as to prevent them from extending from the container and being bulky. Simultaneously, the heated inverter part
106
is cooled down by means of a temperature difference between the inverter part
106
and a low-temperature refrigerant located in the low pressure portion
108
. In this case, furthermore, the inverter part
106
is located on a position different from that of the electrode part
105
to be heated by a high-temperature refrigerant in the high pressure portion
107
. Thus, the inverter part
106
is not or hardly influenced by heat, and the inverter control function is stably achieved for a long time as the temperature of a heating portion such as an inverter chip in the inverter control part is guaranteed. Furthermore, since the electrode part
105
opposite to the high pressure portion
107
is cooled, it becomes easily to make a connection with the electric motor
13
being positioned thereon for cooling.
Here, the high pressure portion
107
is located on the discharge passage side, where the high pressure portion
107
communicates with a discharge port
31
of the compression mechanism
10
. On the other hand, the low pressure portion
108
is located on the intake passage side, where the low pressure portion
108
communicates with a suction port
32
. The compression mechanism
10
sucks the refrigerant from the outside through the suction port
16
of the container
12
and then introduce into the compression mechanism
10
through the inside of the container
12
to compress the sucked refrigerant. After that, the refrigerant is discharged once into the container
12
to cool the electric motor
13
, followed by being discharged to the outside of the container
12
through the discharge port
17
. In this embodiment, the low pressure portion
108
and the high pressure portion
107
, which are naturally occurred in the container
12
, can be used as they are in the above movement of the refrigerant. No special passage design is required. The electrode part
105
and the electric motor
13
are opposite to each other with respect to the high pressure portion
107
and they are easily connected to each other through a short internal wiring
102
. In particular, the low pressure portion
108
is just above the suction port
16
and they are connected to each other through a passage
132
.
In this embodiment, the container
12
is constructed of two structural components, a housing main body
111
and an end wall
112
to be placed on an opening of the housing main body
111
. That is, the housing main body
111
is provided as a single structural component on which the high pressure portion
107
and the low pressure portion
108
are separately formed. In addition, the housing main body
111
is integrally constructed of an end wall
12
b
of the container
12
and the body portion
12
a.
As the opposite end of the container
12
is provided as an opening
12
c,
another end wall
112
is placed on the opening
12
c
and is then fixed with a bolt
113
to construct the container
12
. In such a construction of the container
12
, the pressure difference between the high pressure portion
107
and the low pressure portion
108
is stably received by the housing main body
111
made of the single structural component of the container
12
. When the high pressure portion
107
and the low pressure portion
108
are defined in the container
12
and the inverter control device
101
extends over these portions
107
,
108
, the inverter control device
101
is kept stably even though there is no specific countermeasure for a differential pressure to be required for the connection between the high pressure portion
107
and the low pressure portion
108
. Furthermore, the container
12
of the present embodiment is constructed of two structural components, the number of thick flange portions
33
or bolts
113
for connecting these components are reduced, compared with that of the conventional one constructing of three structural components having two joining points. Thus, such a configuration of the present embodiment also allows the reduction in weight of the compressor, so that it is appropriate to be mounted on the vehicle
27
or the like.
Furthermore, the electric portion
105
and the inverter portion
106
of the inverter control device
101
are formed on an identical substrate
114
. Thus, even though the inverter control device
101
has the electrode portion
105
and the inverter portion
106
which are separately formed thereon, the inverter control device
101
is simply installed in the container
12
using the single substrate
114
so as to be arranged opposite to the high pressure portion
107
and the low pressure portion
108
. A portion of the container
12
facing to the high pressure side of the electrode portion
105
and another portion of the container
12
facing to the low pressure side of the inverter portion
106
are separated from each other through seal members
115
. The configuration of the compressor of the present embodiment satisfies the requirements for providing the structure with no excess space because the compressor is constructed such that the electrode portion
105
and the inverter portion
106
are adjacent to each other, while the high pressure portion
107
and the low pressure portion
108
are adjacent to each other and are opposite to the respective portions
105
,
106
. Thereby, the high pressure condition and the low pressure condition for exerting a predetermined function cannot be impaired by leakage of the refrigerant even though the high pressure portion
107
and the low pressure portion
108
come very close to each other. One of leg portions
34
integrally formed on the container
12
is also provided as a partition between the high pressure portion
107
and the low pressure portion
108
. Such a structure prevents the significant increase in weight to be caused by providing an additional wall for the partition.
As shown in
FIG. 1
, the high pressure portion
107
and the low pressure portion
108
are arranged in a line in the axial direction. In addition, these portions
107
,
108
have their openings
121
,
122
, respectively. As shown in the figure, the inverter control device
101
is placed and fixed on a tubular wall
37
which is slightly extended outward from the periphery of the body portion
12
a
in which the above openings
121
,
122
are formed. The inverter control device
101
is thus easily mounted on the container
12
from the outside to allow both electrode and inverter parts
105
,
106
to face to the high and low pressure portions
107
,
108
, respectively. Here, the electrode portion
105
is formed such that it is provided as the body part
15
a
of the terminal
15
. However, it is not limited to such a structure; it is also possible to prepare the body part
15
a
and the electrode portion
105
as separate components and to join them together.
In the embodiment shown in the figure, the inverter control device
101
is fixed on the opening end of the tubular wall
37
. More specifically, the substrate
114
is placed on the tubular wall
37
through a seal member
123
. The substrate
114
and the tubular wall
37
are joined with a bolt
124
. The seal member
123
is provided as a pressure-tight sealing structure for ensuring the pressure condition in the container
12
. Here, the electrode part
105
and the inverter part
106
are provided on the side of the tubular wall
37
opposite to the container
12
. In other words, these parts
105
,
106
are in an atmospheric pressure region. Thus, the predetermined high pressure portion
107
and the low pressure portion
108
are only ensured in the container
12
such that these portions
107
,
108
are only located between the atmospheric pressure region and the container
12
. On the other hand, the opposite side of the container
12
is opened to the air by means of pressure, so that a simplified mounting structure is obtained without any specific sealing structure that takes pressure in account.
Accordingly, the inverter control device
101
is protected from the influence of dust or water by being covered with a cover
126
, as shown in
FIG. 1
, even though the inverter control device
101
is in the atmospheric pressure region and is opened with respect to pressure. In such a sense, it is preferable to adapt a sealing structure for waterproof and dust control by means of a sealing member
127
. In the embodiment shown in the figure, the cover
126
and the substrate
114
are joined with the bolt
124
. In this case, there is no need to provide the sealing member
127
with a pressure-resisting function. In addition, the cover
126
may be made of resin or rubber. Alternatively, the cover may be of having a mounting structure such as a hook or each of various kinds of engaging parts and fitting parts, which is elastically engaged or fitted with a part of the tubular wall
37
or the substrate
114
to provide a temporal fixed condition.
As shown in
FIG. 1
, the electrode part
105
and the inverter part
106
are connected to each other through a bus-bar
131
. The structure for connecting these parts
105
,
106
is simplified, allowing the reduction in cost and the increase in durability to withstand vibrations or the like.
By the way, the container
12
is made of an aluminum material, allowing the reduction in weight. Thus, it is appropriately mounted on the vehicle
27
or the like. In addition, there is an advantage in which various shapes of the container
12
can be easily obtained by means of a mass production using a die forming.
From the above description, the compressor
11
having the built-in electric motor
13
in each of the cases described above is appropriately applied for a mobile structure to be used together with the battery
1
to be moved. In addition, it is also appropriately applied for constructing a mobile structure such as a vehicle
27
on which the compressor
11
having the built-in electric motor
13
is mounted together with the battery
1
.
The vehicle
27
may not be limited to a specific one such as a gasoline-powered vehicle, a hybrid vehicle, or an electric-powered vehicle. The present invention can be applied on various kinds of the mobile structures including special-purpose vehicles and working-purpose vehicles. In addition, the invention can be applied in air-conditioning systems for domestic use or the like for noise reduction.
According to the present invention, there is no need to provide comparatively long external wirings for connecting between the inverter control device and the container, which has been used in the conventional compressor. In addition, a single terminal is shared between the connections for the inverter control device and the electric motor, so that one of the terminals conventionally used is removed. Thus, the wiring distance is extremely shortened and the decrease in weight of the compressor is achieved. Furthermore, the space for mounting the compressor including the inverter control device is reduced, so that the compressor is more easily mounted on the vehicle or the like. Besides, there is also an advantage in driving load.
According to the invention, furthermore, comparing with the conventional one, the electric connection part of the inverter control device and the electric connection part of the electric motor housed in the body portion of the container become more close to each other. Thus, the length of the wiring in the container is reduced, and the weight and cost of the compressor depending on the wiring is reduced. Furthermore, the compressor of the invention is easily installed in a restricted space of the vehicle or the like since there is no need to increase the axial dimension of the container including the inverter control device.
Although the present invention has been fully described in connection with the preferred embodiment thereof, it is to be noted that various changes and modifications apparent to those skilled in the art are to be understood as included within the scope of the present invention as defined by the appended claims unless they depart therefrom.
