Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an exhaust device, a compressor, and an air conditioner. Background Technology

[0002] The discharge device in a compressor plays a crucial role in air conditioning. Existing compressor discharge valve assemblies typically involve riveting a valve plate and a baffle to a flange. The valve plate head contacts the valve seat on the flange. During the compressor's intake and exhaust processes, the gas pressure inside the cylinder changes from low-pressure gas to high-pressure gas. Once the exhaust pressure is reached, the valve plate opens. The baffle limits the valve plate's lift. After exhaust is complete, the valve plate closes due to its own elasticity and back pressure.

[0003] The exhaust noise from the existing compressor's exhaust device is loud, affecting the user experience. Summary of the Invention

[0004] The problem solved by this invention is that existing exhaust devices produce excessive exhaust noise, which affects the user experience.

[0005] To address the aforementioned problems, embodiments of the present invention provide an exhaust device, a compressor, and an air conditioner, which can improve the problem of excessive exhaust noise from the exhaust device.

[0006] In a first aspect, the present invention provides an exhaust device, comprising a fixed base, a first valve plate, and a second valve plate; the fixed base has an exhaust channel having an exhaust inlet and an exhaust outlet; the first valve plate and the second valve plate are movably mounted on the exhaust channel, and the second valve plate is movably connected to the first valve plate and the second valve plate are partially stacked, the first valve plate being close to the exhaust inlet, and the second valve plate having an exhaust hole; in a closed state, the first valve plate can close the exhaust inlet and the exhaust hole; in an open state, gas can push the first valve plate and the second valve plate to move along the exhaust channel, allowing the first valve plate and the second valve plate to move relative to each other so that the exhaust hole is at least partially exposed.

[0007] This application movably mounts both a first valve plate and a second valve plate in the exhaust channel, making them movably connected and partially overlapping. The first valve plate is located near the exhaust inlet, and the second valve plate has an exhaust hole. When the exhaust device is open, the gas pushes the first and second valve plates to move along the exhaust channel, allowing them to move relative to each other and expose at least part of the exhaust hole. This allows the gas flowing in from the exhaust inlet to pass through the first valve plate, flow to the second valve plate, and finally exit into the exhaust channel through the exhaust hole, reducing the exhaust velocity and thus reducing exhaust noise.

[0008] In an optional embodiment, the flow area of ​​the exhaust channel gradually increases, the exhaust inlet is located on the side with a smaller flow area and corresponds to the first valve plate, and the exhaust outlet is formed on the side with a larger flow area. By setting the flow area of ​​the exhaust channel to gradually increase, placing the exhaust inlet on the side with a smaller flow area, and forming the exhaust outlet on the side with a larger flow area, the gas discharged from the exhaust hole will diffuse within the gradually increasing exhaust channel, resulting in a decrease in exhaust pressure, thereby further reducing exhaust noise.

[0009] In an optional embodiment, the first valve plate and the second valve plate are slidably connected so that they abut against each other and are movable relative to each other. Sliding the valve plate allows for movement of the first and second valve plates while ensuring they abut against each other, thereby exposing the exhaust port portion.

[0010] In an optional embodiment, a slide rail is provided on the side of the first valve plate near the second valve plate, and a slide groove is provided on the side of the second valve plate near the first valve plate, with the slide rail movably mounted in the slide groove; alternatively, a slide groove is provided on the side of the first valve plate near the second valve plate, and a slide rail is provided on the side of the second valve plate near the first valve plate, with the slide rail movably mounted in the slide groove. The combination of the slide rail and the slide groove allows the first and second valve plates to move in a preset direction.

[0011] In an optional embodiment, the first valve plate is provided with a first connecting portion, the second valve plate is provided with a second connecting portion, and the exhaust channel is provided with a first sliding groove and a second sliding groove. Both the first and second sliding grooves are arranged along the extending direction of the exhaust channel. The first connecting portion is movably disposed in the first sliding groove, and the second connecting portion is movably disposed in the second sliding groove. The first connecting portion is provided on the first connecting portion, the second connecting portion is provided on the second valve plate, and the first and second sliding grooves are provided in the exhaust channel to facilitate gas pushing the first and second valve plates.

[0012] In an optional embodiment, the exhaust device further includes a first magnetic component and a second magnetic component. The first magnetic component is disposed at the first connecting portion and / or the second connecting portion, and the second magnetic component is disposed at the first sliding groove and / or the second sliding groove. Disassembly of the first magnetic component and the second magnetic component allows the first valve plate and the second valve plate to reset. By using the first magnetic component and the second magnetic component to reset the first valve plate and the second valve plate, noise generated by collision between the first magnetic component and the second magnetic component can be avoided.

[0013] In an optional embodiment, the number of the first magnetic element includes two, and the number of the second magnetic element includes two. The two first magnetic elements are respectively disposed in the first connecting portion and the second connecting portion, and the two second magnetic elements are respectively disposed in the first sliding groove and the second sliding groove. Distributing the two first magnetic elements in the first connecting portion and the second connecting portion, and distributing the two second magnetic elements in the first sliding groove and the second sliding groove, can better achieve the goal of pushing the first valve plate and the second valve plate to reset.

[0014] In an optional embodiment, the exhaust device further includes a soundproof cover over the exhaust outlet, the soundproof cover having exhaust vents. Installing a soundproof cover at the exhaust outlet can isolate noise transmission and reduce gas flow rate, thereby achieving better noise reduction.

[0015] In a second aspect, the present invention provides a compressor including the exhaust device described in any of the foregoing embodiments.

[0016] The compressor provided in this application movably mounts both a first valve plate and a second valve plate in the exhaust channel, making the first and second valve plates movably connected and partially overlapping. The first valve plate is close to the exhaust inlet, and the second valve plate has an exhaust hole. When the exhaust device is open, the gas pushes the first and second valve plates to move along the exhaust channel, allowing them to move relative to each other so that the exhaust hole is at least partially exposed. This allows the gas flowing in from the exhaust inlet to pass through the first valve plate, flow to the second valve plate, and finally be discharged into the exhaust channel through the exhaust hole, reducing the ejection velocity and thus reducing exhaust noise.

[0017] Thirdly, the present invention provides an air conditioner including the compressor described in the foregoing embodiments.

[0018] The air conditioner provided in this application movably mounts both a first valve plate and a second valve plate in the exhaust channel, allowing the first and second valve plates to be movably connected and partially overlap. The first valve plate is located near the exhaust inlet, and the second valve plate has an exhaust hole. When the exhaust device is open, the gas pushes the first and second valve plates to move along the exhaust channel, causing them to move relative to each other so that the exhaust hole is at least partially exposed. This allows the gas flowing in from the exhaust inlet to pass through the first valve plate, be blocked by it, flow to the second valve plate, and finally be discharged into the exhaust channel through the exhaust hole, reducing the velocity of the exhaust and thus reducing exhaust noise.

Detailed Implementation

[0028] The exhaust noise from the existing compressor's exhaust device is loud, affecting the user experience.

[0029] This invention provides an exhaust device, a compressor, and an air conditioner, which can improve the problem of excessive exhaust noise from the exhaust device.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Please refer to Figure 1 and Figure 2 This embodiment provides an air conditioner, which includes a compressor. The compressor has an exhaust device 100 for exhausting air from the compressor.

[0032] In this embodiment, the exhaust device 100 includes a fixed base 110, a first valve plate 130, and a second valve plate 150. The fixed base 110 is installed at the exhaust port of the compressor. The fixed base 110 has an exhaust passage 111, which has an exhaust inlet 113 and an exhaust outlet 115. The first valve plate 130 and the second valve plate 150 are movably installed in the exhaust passage 111, and the second valve plate 150 is movably connected to the first valve plate 150. The first valve plate 130 and the second valve plate 150 are partially stacked. The first valve plate 130 is close to the exhaust inlet 113, and the second valve plate 150 is located on the side of the first valve plate 130 away from the exhaust inlet 113. The second valve plate 150 is provided with an exhaust hole 151. In the closed state, the first valve plate 130 can close the exhaust inlet 113 and the exhaust hole 151. When the exhaust device 100 is in the open state, the gas can push the first valve plate 130 and the second valve plate 150 to move along the exhaust passage 111, so that the first valve plate 130 and the second valve plate 150 can move relative to each other to expose at least part of the exhaust port 151.

[0033] In this embodiment, the first valve plate 130 and the second valve plate 150 are movably installed in the exhaust channel 111, making the first valve plate 130 and the second valve plate 150 movably connected and partially stacked. An exhaust hole 151 is provided on the second valve plate 150. When the exhaust device 100 is in the open state, the gas pushes the first valve plate 130 and the second valve plate 150 to move along the exhaust channel 111, allowing the first valve plate 130 and the second valve plate 150 to move relative to each other, so that the exhaust hole 151 is at least partially exposed. This allows the gas flowing in from the exhaust inlet 113 to flow through the first valve plate 130 and then through the second valve plate 150, finally being discharged into the exhaust channel 111 through the exhaust hole 151, reducing the exhaust velocity and thus reducing exhaust noise.

[0034] Please refer to Figure 1 , Figure 2 and Figure 5 In this embodiment, the flow area of ​​the exhaust channel 111 gradually increases, the exhaust inlet 113 is located on the side with a smaller flow area of ​​the exhaust channel 111, and the exhaust inlet 113 corresponds to the first valve plate 130. The side with a larger flow area of ​​the exhaust channel 111 forms the exhaust outlet 115. By setting the flow area of ​​the exhaust channel 111 to gradually increase and setting the exhaust inlet 113 on the side with a smaller flow area of ​​the exhaust channel 111, the exhaust outlet 115 is formed on the side with a larger flow area of ​​the exhaust channel 111. The gas discharged from the exhaust hole 151 will diffuse within the gradually increasing exhaust channel 111, resulting in a decrease in exhaust pressure, thereby further reducing exhaust noise.

[0035] In this embodiment, the exhaust channel 111 is frustum-shaped, and the exhaust inlet 113 is provided with a sealing plate 117, which can block the exhaust inlet 113. The sealing plate 117 is provided with an air inlet 119, which is directly opposite to the first valve plate 130. When the exhaust device 100 is closed, the side of the first valve plate 130 away from the second valve plate 150 abuts against the sealing plate 117 and can seal the air inlet 119.

[0036] Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 In this embodiment, the first valve plate 130 and the second valve plate 150 are slidably connected so that the first valve plate 130 and the second valve plate 150 abut against each other and can move relative to each other. Sliding the valve plate 130 and the second valve plate 150 together ensures that the first valve plate 130 and the second valve plate 150 abut against each other while allowing the first valve plate 130 and the second valve plate 150 to move so that the exhaust port 151 is at least partially exposed.

[0037] In other embodiments of this application, the first valve plate 130 and the second valve plate 150 may also be rotatably connected. When the first valve plate 130 and the second valve plate 150 move relative to the exhaust passage 111, the first valve plate 130 and the second valve plate 150 may rotate relative to each other so that the exhaust port 151 is at least partially exposed.

[0038] In this embodiment, a slide rail 131 is provided on the side of the first valve plate 130 near the second valve plate 150, and a slide groove 153 is provided on the side of the second valve plate 150 near the first valve plate 130. The slide rail 131 is movably mounted in the slide groove 153. The cooperation between the slide rail 131 and the slide groove 153 allows the first valve plate 130 and the second valve plate 150 to move in a preset direction.

[0039] In some other embodiments of this application, a groove 153 is provided on the side of the first valve plate 130 near the second valve plate 150, and a slide rail 131 is provided on the side of the second valve plate 150 near the first valve plate 130. The slide rail 131 is movably mounted in the groove 153.

[0040] In this embodiment, to ensure that the first valve plate 130 and the second valve plate 150 are in a contacting and stacked state, the side wall of the slide rail 131 is provided with a limiting platform 133, and the side wall of the slide groove 153 is provided with a limiting groove 155. When the slide rail 131 is inserted into the slide groove 153, the limiting platform 133 is inserted into the limiting groove 155. In other embodiments of this application, in order to prevent the first valve plate 130 and the second valve plate 150 from disengaging from the slide groove 153 and the slide rail 131, the cross-section can be set to an isosceles trapezoid or other structure.

[0041] In this embodiment, to avoid noise between the first valve plate 130 and the second valve plate 150, a damping rubber layer (not shown in the figure) is provided between the first valve plate 130 and the second valve plate 150 for sealing and noise reduction.

[0042] In this embodiment, a first connecting portion 135 is provided on the first valve plate 130. A second connecting portion 137 is provided on the second valve plate 150. The exhaust passage 111 is provided with a first sliding groove 121 and a second sliding groove 123. Both the first sliding groove 121 and the second sliding groove 123 are provided along the extending direction of the exhaust passage 111. The first connecting portion 135 is movably disposed in the first sliding groove 121, and the second connecting portion 137 is movably disposed in the second sliding groove 123. By providing the first connecting portion 135 on the first connecting portion 135, the second connecting portion 137 on the second valve plate 150, and the first sliding groove 121 and the second sliding groove 123 in the exhaust passage 111, gas can easily push the first valve plate 130 and the second valve plate 150.

[0043] To allow the first valve plate 130 and the second valve plate 150 to move relative to each other and expose the vent when sliding along the first slide groove 121 and the second slide groove 123, in this embodiment, the first connecting portion 135 can only move along the first slide groove 121 and cannot disengage from it, and the second connecting portion 137 can only move along the second slide groove 123 and cannot disengage from it. Therefore, when the first valve plate 130 and the second valve plate 150 are pushed to move, the flow area of ​​the exhaust channel 111 gradually increases, allowing the first valve plate 130 and the second valve plate 150 to move relative to each other, thereby exposing the vent.

[0044] Specifically, the first slide 121 and the second slide 123 are C-shaped slides 153, and the first connecting part 135 and the second connecting part 137 are matched with the first slide 121 and the second slide 123, thereby preventing the first connecting part 135 from disengaging from the first slide 121 and preventing the second connecting part 137 from disengaging from the second slide 123.

[0045] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5In this embodiment, the exhaust device 100 further includes a first magnetic element 181 and a second magnetic element 183. There are two first magnetic elements 181 and two second magnetic elements 183. The two first magnetic elements 181 are respectively disposed in the first connecting portion 135 and the second connecting portion 137, and the two second magnetic elements 183 are respectively disposed in the first sliding groove 121 and the second sliding groove 123. The detachment of the first magnetic elements 181 and the second magnetic elements 183 allows the first valve plate 130 and the second valve plate 150 to reset. By using the first magnetic elements 181 and the second magnetic elements 183 to reset the first valve plate 130 and the second valve plate 150, noise generated by the collision of the first magnetic elements 181 and the second magnetic elements 183 can be avoided.

[0046] In other embodiments of this application, the number of the first magnetic element 181 and the second magnetic element 183 may both be one. When the first magnetic element 181 is disposed in the first connecting portion 135, the second magnetic element 183 is disposed in the second sliding groove 123. When the first magnetic element 181 is disposed in the second connecting portion 137, the second magnetic element 183 is disposed in the second sliding groove 123.

[0047] In this embodiment, both the first magnetic element 181 and the second magnetic element 183 are permanent magnets. The magnetic pole of the first magnetic element 181 near the second magnetic element 183 is the same as the magnetic pole of the second magnetic element 183 near the first magnetic element 181, thereby generating a repulsive force to reset the first valve plate 130 and the second valve plate 150.

[0048] In other embodiments of this application, the first valve plate 130 and the second valve plate 150 can also be reset by elastic elements or the like.

[0049] Please refer to Figure 1 , Figure 2 and Figure 8 In this embodiment, the exhaust device 100 further includes a soundproof cover 190, which covers the exhaust outlet 115 and has an exhaust through hole 191. The soundproof cover 190, located at the exhaust outlet 115, can isolate noise transmission and reduce gas flow rate, thereby achieving better noise reduction.

[0050] The working principle and beneficial effects of the exhaust device 100, compressor, and air conditioner provided in this embodiment of the invention include:

[0051] In this embodiment, the first valve plate 130 and the second valve plate 150 are movably installed in the exhaust channel 111, making the first valve plate 130 and the second valve plate 150 movably connected and partially stacked. An exhaust hole 151 is provided on the second valve plate 150. When the exhaust device 100 is in the open state, the gas pushes the first valve plate 130 and the second valve plate 150 to move along the exhaust channel 111, allowing the first valve plate 130 and the second valve plate 150 to move relative to each other, so that the exhaust hole 151 is at least partially exposed. This allows the gas flowing in from the exhaust inlet 113 to flow through the first valve plate 130 and then through the second valve plate 150, finally being discharged into the exhaust channel 111 through the exhaust hole 151, reducing the exhaust velocity and thus reducing exhaust noise.

[0052] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
