Description of the Invention (4) > Noise (abnormal sound) is transmitted to the indoor heat exchanger 20 through the refrigerant. On the one hand, such as • As shown in FIG. 12 • Since the first to third capillaries 11 to 13 connecting the valve body 2 and the solenoid valve device 10 are exposed outside the housing 24, they are deformed with less impact. Disadvantages of Poor Operation "Inventions created to solve such problems have been disclosed in Japanese Patent Publication No. Sho 60-12459. No. 5 · This invention is as shown in Fig. 13 • The type of the high-pressure exhaust gas discharged from the compressor section 22 is filled in the hermetically sealed case 2 4 housing the compressor section 22 and the motor section 27. In the compressor, since the copper # 1 and the solenoid valve device 10 are arranged in the casing 24, the piping is not m_: and the damage of the capillary tube can be prevented. However, even in this structure, the structure is not complicated and large. And because the four-way valve device 1 is installed in the casing 24, the compressor body becomes large and cannot be handled. New problems in the trend of miniaturization of compressors in recent years. In addition, since the four-way valve device 1 is configured to operate with a pressure difference, the slide valve 5 must be closely contacted with the valve seat, and the pressure balance (gas balance) between the pipes is difficult to handle when the valve is stopped. It is inconvenient. That is, at this time, it takes a long time to balance the pressure, so it cannot be restarted quickly after the stop, or the air-conditioning, heating room transportation (please read the precautions on the back before filling in this Page} This paper size applies to the Chinese national standard (CNS > A4 size (2 丨 0X297 mm) 44534 8 A7 B7 printed by the Consumers' Cooperatives of the Central Bureau of Standards, Ministry of Economic Affairs. 5. Description of the invention (5) Switching · " In addition, the fluid compressor must be provided with two types of the four-way valve device 1 and the electromagnetic switching valve device 10 in the casing 24. The four-way valve device 1 is a direct-acting type. 2 is formed in a long direction in one direction. Therefore, the degree of freedom of the installation position of the four-way valve device 1 is low, and the high-pressure gas introduction pipe 3 opening in the casing 24 is formed from the central axis of the casing 24 keep away In the case where the opening is close to the inner peripheral wall of the case 24, ^ The lubricating oil used to lubricate the driving motor 23, etc. is scattered in the case 24, and close to the inner peripheral wall of the case 24. In particular, there is a lot of scattering. In this way, because the lubricating oil is sucked in a large amount in the pressurized gas introduction pipe 3, the amount of lubricating oil in the casing 24 is reduced, and the lubricating oil intrudes into the outdoor side or The indoor side knows the inside of the exchanger, so there is a problem of reducing the heat exchange performance of the heat exchanger β \ Also, in the conventional switching valve device 1, as the material of the slide valve 5, a low heat-resistant plastic is used. In the case 2 4 There is no problem when the above-mentioned switching valve device 1 is arranged on the outside, but when it is installed inside the casing 24, if the inside of the casing 24 is heated to a relatively high temperature, and the switching valve device 1 is welded to the casing 25, Then, the transmission to the valve body 2 causes heat to be applied to the slide valve 5, so that the low-heat-resistant plastic has a problem of reducing reliability.

Description of the invention (26) Γ The position of the stack is reduced, so the first and second connecting valves d 5 9, 6 can be reduced. 1 and the amount of lubricating oil discharged to the outside of the shell β. Therefore, the amount of lubricating oil + in the fluid shrinking machine can be kept constant, and the heat exchange capacity of the heat exchanger can be prevented from being reduced. Because the switching valve portion 28 is formed in a rotary type, the switching collision sound generated in the conventional reciprocating type can be reduced, and because the switching valve portion 28 is provided in the casing 25, even if noise occurs, The noise cancellation effect of the shell 25 (large capacity and cut off from the outside) can effectively prevent the noise from leaking to the outside. However, since the oil separation plate 51 and the switching valve portion 28 are provided at overlapping positions, the oil separation plate 51 also functions as a sound insulation plate, which can effectively prevent the compressor portion 26 or the motor portion. 2 7 The noise transmitted to the piping and leaked to the outside. Therefore, the present invention is particularly effective when using the above-mentioned HFC-based refrigerant instead of the refrigerant. First, it has the effect of simplifying the exhaust piping of the air conditioner. The holes 6 7 are opened in the above-mentioned case 25, so that no piping for high-pressure gas is required. In addition, with the conventional anti-vibration measures required for piping for high-pressure gas becoming unnecessary, the switching valve section 55 is different from the conventional small-scale test type in that it does not use a solenoid valve for operation. For the device, the capillary tube (shown in Figures 12 and 13 of Figures 1 and 12) required for the conventional switching valve becomes unnecessary. Therefore, the assembly of the compressor with the switching valve is easy, and With a simple structure, the effect of an air conditioner with less vibration can be obtained.

Description of the invention (π) The second has the effect of miniaturizing the compressor 0, that is, the switching valve part 2 8 built in the casing 2 5 of the compressor is different from the conventional example. It is a rotary type t Also »Because there is no solenoid valve device for operation, the total length can be reduced. • When the compressor is stopped, the valve body 5 3 borrows it .. The weight itself will be slightly reduced by 1, so Wfl. ≪ Above The tightly connected state between the valves μ 5 2 is a state where the valve M 5 3 can be turned by a low-torque TV. This point > In the conventional example, the above sliding valve system is often tightly connected to the valve seat > Large torque. Therefore, in the present invention, »the magnetic switching unit 5 5 can be made small due to the component 1. From the above t, it is not necessary to increase the size of the casing 2 5 and the switching valve portion 2 can be increased. 8 Installed in the casing 2 5 of the compressor mentioned above »Therefore, it can fully correspond to the effect of the miniaturization trend of the M shrinking machine in recent years. The third can reduce the switching valve portion 2 8 • Used in the casing 2 5 Can improve the reliability of leaks or the operability of welding operations. That is, in the conventional example, the piping connected to the heat exchanger of the indoor side of the above-mentioned suction pipe and the heat exchanger of the outdoor side of the heat exchanger (4 & gt 6 7) The structure is taken out of the shell 2 and pulled out of the shell 2 4 separately. »Because the above-mentioned four-way valve device 1 is a direct-acting quasi-local type, the above piping systems are arranged in series 0, so they are connected with the shell 2 4 ZZ. M___ X. The welding length of 4 & will become longer »and there is a problem in airtightness. 0π cooperation. However, in the present invention, the above piping system is mounted on the upper part of the housing in a circumferential shape, protruding outward from the casing 2 5 Round valve seat 5 2 Therefore, it is necessary to install the switching valve part 2 8 on the casing 2 5 t. Weld the valve seat 2 8 to the casing 2 5 only.

Description of the invention (28) C. Therefore, it has the effect of shortening the welding length, improving the reliability of sick gas and welding workability. 4. It has the effect that the gas balance at the time of stopping can be easily and quickly performed. That is, in the past reciprocating slide valve, in order to prevent the compression leakage, the above-mentioned slide valve system must often tightly seal the valve seat, and gas balance cannot be implemented in the part of the switching valve. It is necessary to wait a long time until the part of the expansion mechanism becomes gas equilibrium. However, in the present invention, when the valve body 5.3 is slightly lowered by its own weight when stopped, the distance between the valve body 5 and the valve seat 52 is enlarged. Gap • Therefore, all the valve ports 5 9 to 6 1 provided in the valve seat 5 2 communicate with each other through a gap generated between the valve body 5 3 and the upper surface of the valve body 5 3, and the gas balance can be quickly implemented. During operation, due to the pressure in the casing 25, the valve body 5 3 is pressed and tightly contacted to the valve seat 52, which does not cause leakage of compressed gas, and it is formed so as to be difficult to move in the direction of rotation. Therefore, the gas balance after the stop can be easily and quickly performed, and the restart after the stop or the switching between air-conditioning and heating can be performed quickly, and the effect of the gas balance can be quickly performed without waiting for a long time when the refrigerant is injected. * Fifth, it has the effect of reducing the power used to control the switching valve portion 28. That is, because the above-mentioned pull rod 7 2 is made of iron, the pull rod 7 is not magnetized except when the valve seat 52 is driven. 2. Also borrow the pull bar 7 2 and above (please read the notes on the back before filling this page) The size of the paper is applicable to the Chinese national standard (CNS > Α4 size (210X297 mm) -31-Central Ministry of Economic Affairs Printed by Zhunju Bureau Shellfish Consumer Cooperative Co., Ltd. 44534 8 a? B7 V. Description of the Invention (29) r The attraction of the magnet member 5 4 can maintain the switching position. Therefore, it is necessary to maintain the sliding valve by means of springs and electromagnets. The conventional example of the position is different. During operation, it is not necessary to apply a voltage to the magnetic switching unit 55, so the power consumption can be reduced. No.6, a highly reliable four-way valve built-in fluid can be obtained for the temperature inside the case. Compressor. That is, in the conventional reciprocating compressor, the sliding valve is made of plastic with low heat resistance. There is no problem when the switching valve is provided outside the compressor casing. When the switching valve part 2 8 is provided in 2 5, the case 2 5 will become a relatively high temperature state, and because the switching valve portion 2 8 is welded to the case 2, the temperature during welding is transmitted to the switching valve 2 8 * Therefore, if it is a plastic with low heat resistance, it will be reliable. However, in the present invention, the valve body 5 3 is formed of non-magnetic metals such as heat-resistant zinc, brass, and aluminum. Also, the valve body 5 3 is pushed toward the above by the high pressure in the housing. The valve seat 5 2 maintains i-tightness, so there are very few problems in preventing air leakage. Therefore, it has the effect of reliable operation against the temperature inside the case 2 5 * The following description * Refer to Figure 10 A second embodiment of the present invention. The same components as those in the first embodiment described above are denoted by the same reference numerals, and a description thereof will be omitted. The second embodiment relates to an actuator of the switching valve portion 28, that is, to an improvement of the magnetic switching portion 55.

Invention Explanation (30) r It is believed that the position where the oil separation plate 51 overlaps, and it is believed that the interference between the switching valve portion 28 and the oil separation plate 51 will be a problem, and the problem that the compressor cannot be lowered will be caused. When the outer diameter of the casing 25 is reduced to miniaturize the compressor * It is believed that the interference between the magnetic switching portion 5 5 of the switching valve portion 28 and the inner wall surface of the casing 25 will become a problem * Here * In the '2nd embodiment, the above-mentioned switching valve portion is formed in the shape shown in (a) and (b) of the same figure. That is, in the above-mentioned first embodiment, the pull bar 7 2 of the magnetic switching portion 55, The base ends of 72 are set to be parallel to each other. However, in the second embodiment, the center axis of the valve seat 52 is used. 5 8 Fan-shapedly opened the base end portion of the pull bar 7 2 * 72 as a center, and an arc-shaped electromagnet 1 1 5 was set in the middle along the outer diameter of the valve seat 5 2 and the valve body 53. The electromagnet 115 is composed of an iron core 1 1 6 having an arc-shaped centerline, and a coil 1 1 7 having the same number of windings as the first embodiment described above in the first embodiment. * Because the electromagnet 5 has The number of turns 1 1 7 is the same as the number of turns of the electromagnet 74 of the first embodiment. Therefore, the same force as that of the electromagnetic section 7 4 of the first embodiment is generated.
