Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

The present application provides a compressor (not shown) for compressing a gaseous refrigerant to be discharged in a state of high temperature and high pressure, thereby circulating the refrigerant in a refrigeration system so that the refrigeration system can provide an air conditioning effect to a designated area. Of course, during the circulation of the refrigerant in the refrigeration system, the gaseous refrigerant is sucked by the compressor to be repeatedly compressed and discharged.

Wherein, the compressor has a compression chamber (not shown) and a discharge chamber (not shown) inside. The compression chamber can suck gaseous refrigerant from the refrigeration system and compress the gaseous refrigerant in the compression chamber; the compressed gaseous refrigerant is introduced into the discharge chamber, so that the high-temperature and high-pressure refrigerant can be led out of the compressor through the discharge chamber, and the high-temperature and high-pressure refrigerant enters the refrigerant circulation circuit. When the gas pressure in the compression cavity is increased, the high-pressure refrigerant needs to be introduced into the exhaust cavity; at the same time, when the pressure in the compression chamber is reduced, it is necessary to ensure that the refrigerant in the discharge chamber does not flow back into the compression chamber.

In the prior art, a compressor employs a valve plate and a flapper to form a check valve. Opening the valve plate when the air pressure of the compression cavity is higher than that of the exhaust cavity, so that the refrigerant in the compression cavity can be guided into the exhaust cavity; the valve plate is closed when the pressure in the compression chamber is lower than the discharge chamber to prevent the refrigerant from flowing backward. However, when the valve plate is closed, the valve plate impacts the baffle due to large air pressure difference, so that abnormal sound is caused; in addition, the valve plate is opened and closed frequently due to frequent air pressure change of the compression cavity, and the valve plate is easy to damage.

In view of the above, referring to fig. 1, in order to improve the above-mentioned problems, in other words, to improve the technical problem that the exhaust assembly 10 is easily damaged and easily causes abnormal sound in the prior art, the exhaust assembly 10 and the compressor using the exhaust assembly 10 of the present application are provided.

The discharge assembly 10 is installed between the discharge chamber and the compression chamber. When the gaseous refrigerant in the compression chamber is compressed into a high-temperature and high-pressure refrigerant, the high-pressure refrigerant may be introduced into the discharge chamber through the discharge assembly 10. When the gaseous refrigerant in the compression chamber is depressurized to draw the gaseous refrigerant from the refrigeration system, the discharge assembly 10 is closed to prevent the refrigerant in the discharge chamber from flowing back into the compression chamber.

Referring to fig. 1 and 2 in combination, in an embodiment of the present application, a vent assembly 10 includes a body 100 and a hinge assembly 200. The main body 100 is for being installed inside the compressor such that the discharge chamber and the compression chamber are located at opposite sides of the main body 100, respectively. In addition, the main body 100 is provided with a first sliding groove 110 and a first exhaust hole 120, one end of the first sliding groove 110 is used for being communicated with a compression cavity of the compressor, and the other end is used for being communicated with an exhaust cavity of the compressor. One end of the first exhaust hole 120 is used for being communicated with the compression cavity, and the other end is used for being communicated with the exhaust cavity; the first chute 110 and the first exhaust hole 120 are spaced apart. The hinge assembly 200 includes a first moveable member 210, a second moveable member 230, and a linkage member 220; the first movable member 210 is movably disposed in the first sliding slot 110; second movable member 230 is movably connected to main body 100; the linkage 220 has one end connected to the first moveable member 210 and the other end connected to the second moveable member 230. The first movable member 210 is adapted to slide in the first sliding slot 110 under the condition that the pressure difference exists between the air pressure in the compression chamber and the air pressure in the exhaust chamber, so as to drive the second movable member 230 to open the first exhaust hole 120 when the pressure in the compression chamber is higher than the pressure in the exhaust chamber, or to close the first exhaust hole 120 when the pressure in the compression chamber is lower than the pressure in the exhaust chamber.

As described above, under the condition that the air pressure of the compression chamber is higher than the air pressure of the exhaust chamber, the first movable element 210 slides along the first sliding groove 110, so that the second movable element 230 slides along the main body 100 under the driving action of the linking element 220 to open the first exhaust hole 120, at this time, the first exhaust hole 120 can communicate the exhaust chamber and the compression chamber, and the gas in the compression chamber can be introduced into the exhaust chamber, as shown in fig. 2. Under the condition that the air pressure of the compression chamber is lower than the air pressure of the exhaust chamber, the first movable member 210 slides along the first sliding slot 110, and the second movable member 230 slides along the main body 100 under the driving action of the linking member 220 to close the first exhaust hole 120, so that the gas in the exhaust chamber can be prevented from flowing back to the compression chamber, as shown in fig. 1. Due to the linkage relationship between the first movable member 210 and the second movable member 230, the first exhaust hole 120 can be opened or closed by the first movable member 210 and the second movable member 230 in a sliding manner, so that the first movable member 210 and the second movable member 230 can be prevented from being impacted with other parts, the problem that the first movable member 210 and the second movable member 230 are easily damaged can be avoided, and the problem of abnormal sound can be improved. Based on this, this exhaust assembly 10 can improve the technical problem that prior art exhaust assembly 10 is fragile and easily causes the abnormal sound.

It should be noted that, when the air pressure of the compression cavity is higher than the air exhaust cavity, the air pressure at the end of the first sliding chute 110 close to the compression cavity is higher than the air pressure at the end close to the air exhaust cavity, so that the air close to one side of the compression cavity applies an acting force to the first movable member 210, the first movable member 210 moves away from the compression cavity, and the second movable member 230 is driven by the linkage member 220 to move, the second movable member 230 opens the first air exhaust hole 120, and the air in the compression cavity can be introduced into the air exhaust cavity from the first air exhaust hole 120. After the refrigerant in the compression chamber is completely led into the exhaust chamber, the compression chamber sucks the refrigerant from the refrigerating system, and the air pressure in the compression chamber is lower than that in the exhaust chamber; therefore, the first movable member 210 is acted by the force of the exhaust chamber side, so that the first movable member 210 moves close to the compression chamber, and simultaneously drives the linkage member 220 and the second movable member 230, and the second movable member 230 can close the first exhaust hole 120, thereby preventing the refrigerant in the exhaust chamber from flowing back to the compression chamber.

Optionally, in the embodiment of the present application, the main body 100 is further provided with a first air cavity 130, and the first air cavity 130 is used for communicating with the compression cavity; the first chute 110 and the first exhaust hole 120 are both in communication with the first air chamber 130.

Wherein the first air chamber 130 may be divided into a lead-in section 131 and an air pressure section 132. The leading-in section 131 is used for being communicated with the compression cavity; the extending direction of the gas pressure section 132 and the extending direction of the introducing section 131 form an included angle, and the introducing section 131 is located at one end of the gas pressure section 132, so that when the gaseous refrigerant of the compression cavity is introduced into the first gas cavity 130, the gaseous refrigerant passes through the introducing section 131 and then enters the gas pressure section 132, the high-pressure gaseous refrigerant can be prevented from directly impacting on the first movable member 210, the situation that the first movable member 210 is damaged due to overlarge acting force can be prevented, meanwhile, the gas is reflected for multiple times in the introducing section 131 and the gas pressure section 132, and the purpose of reducing noise can be achieved.

In some embodiments of the present application, the first sliding groove 110 and the first exhaust hole 120 are respectively located at two ends of the air pressure section 132, and optionally, the introduction section 131 may be located at one end of the air pressure section 132 corresponding to the first sliding groove 110, thereby preventing high-pressure gaseous refrigerant from directly entering the first exhaust hole 120, so that the gaseous refrigerant may undergo multiple reflections before entering the first exhaust hole 120, so as to achieve a noise reduction condition. It should be understood that in other embodiments of the present application, the position of the introduction section 131 may be located at other positions of the pneumatic section 132.

It should be noted that the above-mentioned "reflection" refers to a condition that the gaseous refrigerant impacts on the inner peripheral wall of the first air cavity 130 to change the flow direction in the process of flowing along the introduction section 131 and the air pressure section 132.

Of course, in other embodiments of the present application, the introduction section 131, the pneumatic section 132, or the entire first air chamber 130 may be eliminated.

Referring to fig. 3, fig. 4 and fig. 5, in order to ensure the sliding stability between the first movable element 210 and the first sliding slot 110, a first sliding rail 112 is disposed on an inner wall of the first sliding slot 110, and an extending direction of the first sliding rail 112 is the same as an opening direction of the first sliding slot 110; correspondingly, the first movable member 210 is provided with a sliding groove 211. Through the sliding fit of the first sliding rail 112 and the sliding groove 211, the stability of the first movable member 210 sliding along the first sliding groove 110 can be improved. It should be understood that, in other embodiments of the present application, the sliding groove 211 may be opened on the inner wall of the first sliding groove 110, and the first sliding rail 112 may be provided on the first movable member 210; of course, the first slide rail 112 and the slide groove 211 may be eliminated.

In addition, referring to fig. 6, in order to prevent the first movable member 210 from coming out of the first sliding groove 110, optionally, in some embodiments of the present application, the exhaust assembly 10 further includes a stopper 111, and the stopper 111 is disposed in the first sliding groove 110 and is used for abutting against the first movable member 210 to limit the first movable member 210 from moving towards the compression cavity. The stopper 111 protrudes from an inner wall of the first sliding groove 110, so that the first movable element 210 can be abutted against the stopper 111 when the first movable element 210 moves close to the first air cavity 130, and the stopper 111 limits the movement of the first movable element 210 to prevent the first movable element 210 from coming out of the first sliding groove 110.

In some embodiments of the present application, the first sliding groove 110 is a square hole groove, and the shape of the first movable member 210 is adapted to the shape of the first sliding groove 110, so that the first sliding groove 110 can limit the rotation of the first movable member 210, and the stability of the first movable member 210 is ensured. Of course, in other embodiments of the present application, the first sliding groove 110 may also have other shapes, such as a circle, an oval, a trapezoid, or a diamond. Of course, in the case where the first slide rail 112 and the slide groove 211 are provided, the first movable member 210 may be prevented from rotating by the cooperation of the first slide rail 112 and the slide groove 211.

It should be noted that, in some embodiments of the present application, the stopper 111 has a certain distance from the opening of the first sliding groove 110 close to the first air cavity 130, so that when the first movable element 210 abuts against the stopper 111, a part of the first sliding groove 110 is not occupied by the first movable element 210, which can facilitate the gas in the first air cavity 130 to enter the first sliding groove 110 and provide an acting force to the first movable element 210, thereby increasing the reaction speed of the first movable element 210 when the air pressure of the compression cavity is higher than the air pressure of the exhaust cavity, and improving the sensitivity. Of course, in other embodiments of the present application, the stopper 111 may be located at the opening of the first chute 110.

It should be noted that in other embodiments, the aperture of the end of the first sliding groove 110 close to the first air cavity 130 is reduced to provide a limiting function for the first movable element 210, and it can also be considered that the stopper 111 is disposed inside the first sliding groove 110.

In some embodiments of the present disclosure, the second movable member 230 is movably connected to a side of the main body 100 away from the first air chamber 130, and meanwhile, the link member 220 is also disposed on a side of the main body 100 away from the first air chamber 130, so that the compression chamber can be conveniently applied to the first movable member 210 in a high pressure state, thereby facilitating the movement of the first movable member 210 and the second movable member 230.

In addition, the moving direction of the second movable member 230 forms an included angle with the moving direction of the first movable member 210. Based on this, in the process that the first movable member 210 drives the second movable member 230 to move through the linkage member 220, the moving speed and the moving distance of the second movable member 230 can be reduced, so that the technical problems that the second movable member 230 collides with other parts to generate abnormal sound and generate abnormal sound are further improved. Of course, in order to ensure that the second movable member 230 can be driven to move in the moving process of the first movable member 210, one end of the linkage member 220 is movably connected to the first movable member 210, and the other end of the linkage member 220 is movably connected to the second movable member 230. Therefore, in the process that the first movable member 210 slides along the first sliding groove 110, the end of the linkage member 220 not only moves along the first sliding groove 110 along with the first movable member 210, but also the linkage member 220 rotates along the first movable member 210, so that the linkage member 220 can conveniently drive the second movable member 230 to move.

It should be noted that, due to the movable connection between the linking member 220 and the first movable member 210 and the second movable member 230, the first movable member 210 and the second movable member 230 can move in different directions. Based on this, the position setting requirements for the first movable member 210 and the second movable member 230 can be reduced, the positions of the first movable member 210 and the second movable member 230 can be adjusted according to actual conditions, and manufacturing and design costs are reduced.

It should be understood that in other embodiments of the present application, the first moveable member 210 and the second moveable member 230 may be arranged differently. For example, the first movable member 210 and the second movable member 230 move in the same direction, in which case the connection between the linkage member 220 and the first and second movable members 210 and 230 may be a fixed connection. For another example, the moving directions of the first movable member 210 and the second movable member 230 are opposite, and at this time, the linking member 220 can be set to be a lever structure, so as to achieve the purpose that the first movable member 210 drives the second movable member 230 to move.

Optionally, in some embodiments of the present application, the linkage member 220 is a rigid structure, and one end of the linkage member 220 is hinged to the first movable member 210, and the other end is hinged to the second movable member 230. The rigid structure means that the linkage member 220 itself is not easily elastically deformed, so that the sensitivity of the first movable member 210 driving the second movable member 230 to slide can be improved, and the stability of the linkage between the first movable member 210 and the second movable member 230 can also be improved.

It should be noted that, in the embodiment of the present application, the first movable member 210 and the linkage member 220 are substantially rod-shaped structures, and the second movable member 230 is substantially block-shaped. The first moving member 210, the linkage member 220 and the second moving member 230 together form a multi-link structure, and in the process that the first moving member 210 slides along the first sliding slot 110, the linkage member 220 is driven by the first moving member 210, and the linkage member 220 pulls or pushes the second moving member 230 to slide along the main body 100, so that the first exhaust hole 120 can be opened or closed.

In addition, since the linkage member 220 is rod-shaped, when the first movable member 210 moves a certain distance away from the compression cavity, a larger included angle is formed between the linkage member 220 and the moving direction of the second movable member 230, at this time, the component force of the linkage member 220 to the second movable member 230 in the moving direction thereof gradually decreases, and the component force in the direction perpendicular to the moving direction of the second movable member 230 gradually increases, so that the friction force between the second movable member 230 and the second sliding rail 231 increases to cause the second movable member 230 to be self-locked; in other words, by the arrangement of the rigid linkage element 220, the moving direction of the first moving element 210 and the moving direction of the second moving element 230 form an included angle, the first moving element 210, the linkage element 220 and the second moving element 230 can form self-locking when the first moving element 210 is far away from the compression cavity by a sufficient distance, so that the first moving element 210 can be prevented from coming off the first sliding groove 110, and the second moving element 230 can be prevented from coming off the second sliding rail 231.

In addition, referring to fig. 3 and fig. 7 in combination, in order to enable the second movable member 230 to stably slide along the main body 100, in some embodiments of the present application, a second sliding rail 231 is disposed on the main body 100, a second sliding slot 232 is disposed on the second movable member 230, and the second sliding rail 231 is slidably engaged with the second sliding slot 232. Through the cooperation of the second sliding rail 231 and the second sliding groove 232, not only a guiding function can be provided to the second movable member 230, so that the second movable member 230 can stably move in a set direction to stably open or close the first exhaust hole 120. In addition, in the embodiment of the present application, the width of the second sliding rail 231 gradually increases from the side close to the main body 100 to the side away from the main body 100, so that under the condition that the second sliding rail 231 is engaged with the second sliding groove 232, the second sliding rail 231 can provide a limiting effect for the second movable member 230, and the second movable member 230 is prevented from being separated from the second sliding rail 231 along the direction perpendicular to the second sliding rail 231, thereby ensuring the sliding stability of the second movable member 230. It should be understood that in other embodiments of the present application, the second sliding rail 231 may also be disposed on the second movable member 230, and correspondingly, the second sliding groove 232 is formed on the main body 100.

In addition, in the embodiment of the present application, please continue to refer to fig. 1, fig. 2 and fig. 8, the main body 100 is further provided with a second air cavity 140, the first chute 110 and the first exhaust hole 120 are both communicated with the second air cavity 140, the exhaust assembly 10 further includes a baffle 300, and the baffle 300 covers the second air cavity 140; the baffle 300 is provided with a second exhaust hole 310, the second exhaust hole 310 is communicated with the second air cavity 140, and the second exhaust hole 310 is used for being communicated with the exhaust cavity. It should be noted that the linkage member 220, the second movable member 230 and a portion of the first movable member 210 are disposed in the second air cavity 140, so that the first movable member 210, the linkage member 220 and the second movable member 230 can be prevented from being affected by other parts during movement, and stability of linkage of the first movable member 210, the linkage member 220 and the second movable member 230 can be ensured. In addition, due to the second air cavity 140, when the air is exhausted from the first exhaust hole 120, the air pressure of the air is suddenly reduced, and the flowable space is increased, so that the air flows are interfered and reflected with each other, thereby achieving the purpose of reducing noise.

Alternatively, the first exhaust hole 120 is opened toward one end of the baffle 300, and the second exhaust hole 310 is opened at the other end of the baffle 300. In other words, in some embodiments of the present application, the first sliding chute 110 and the first exhaust hole 120 are respectively located at two opposite ends of the baffle 300, and the second exhaust hole 310 is opened at one end of the baffle 300 close to the first sliding chute 110, so that in the process of opening the first exhaust hole 120 for exhausting, the airflow guided by the first exhaust hole 120 can be exhausted from the second exhaust hole 310 after multiple reflections, and the purpose of reducing noise can be achieved. It should be understood that in other embodiments of the present application, the second exhaust hole 310 may be opened at other positions of the baffle 300, for example, the middle portion of the baffle 300.

In addition, in some embodiments of the present application, the second exhaust hole 310 may be provided in plurality, and the plurality of second exhaust holes 310 are spaced apart from each other on the baffle 300. By setting the number of the second exhaust holes 310 to be plural, the apertures of the plural second exhaust holes 310 can be made smaller, thereby reducing the speed of the air flow guided out from the second exhaust holes 310, and also achieving the purpose of reducing noise. It should be understood that in other embodiments of the present application, only one second exhaust hole 310 may be opened.

In order to facilitate the second exhaust hole 310 to exhaust, in some embodiments of the present application, the second exhaust hole 310 is disposed obliquely. It should be noted that the second discharge hole 310 is inclined in such a manner that one end of the second discharge hole 310 communicating with the second air chamber 140 is inclined toward one side of the first discharge hole 120, thereby allowing the second discharge hole 310 to be disposed substantially toward the first discharge hole 120, thereby facilitating the air flow to be guided out from the second discharge hole 310 when the air flow flows from the first discharge hole 120 to the second discharge hole 310. It should be understood that in other embodiments, the inclined arrangement of the second exhaust hole 310 may be eliminated.

In summary, the exhaust assembly 10 and the compressor provided in the embodiment of the present application can slide along the first sliding groove 110 under the condition that the air pressure of the compression cavity is higher than the air pressure of the exhaust cavity, so that the second moving member 230 slides along the main body 100 under the driving action of the linking member 220 to open the first exhaust hole 120, at this time, the first exhaust hole 120 can communicate with the exhaust cavity and the compression cavity, and the air in the compression cavity can be introduced into the exhaust cavity. Under the condition that the air pressure of the compression chamber is lower than that of the exhaust chamber, the first movable member 210 slides along the first sliding groove 110, and the second movable member 230 slides along the main body 100 under the driving action of the linkage member 220 to close the first exhaust hole 120, so that the gas in the exhaust chamber can be prevented from flowing back to the compression chamber. Due to the linkage relationship between the first movable member 210 and the second movable member 230, the first exhaust hole 120 can be opened or closed by the first movable member 210 and the second movable member 230 in a sliding manner, so that the first movable member 210 and the second movable member 230 can be prevented from being impacted with other parts, the problem that the first movable member 210 and the second movable member 230 are easily damaged can be avoided, and the problem of abnormal sound can be improved. Based on this, this exhaust assembly 10 can improve the technical problem that prior art exhaust assembly 10 is fragile and easily causes the abnormal sound. In addition, it is also possible to provide a noise reduction effect to the exhaust of the first exhaust holes 120 through the second air chamber 140, thereby reducing noise generated from the exhaust assembly 10.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the utility model as defined in the appended claims.
