Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the suction muffler and the compressor according to the present invention will be described in further detail by examples with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
Referring to fig. 1 to 3, an embodiment of the invention provides an intake silencer 10, which includes a housing 100 and an oil retainer 200, wherein an oil leakage hole 110 is formed on a bottom wall of the housing 100, and the oil leakage hole 110 is communicated with an interior of the housing 100. The oil slinger 200 is provided on the bottom wall of the housing 100 at the outer periphery of the oil drain hole 110, and the radial area of the oil slinger 200 increases in a direction away from the housing 100.
The shape of the oil slinger 200 may be various, for example, the oil slinger 200 may be annular, i.e., the cross section of the oil slinger 200 is annular. Or the cross-section of the slinger 200 is rectangular. Or alternatively, the cross-section of the slinger 200 may be elliptical, etc.
According to the suction muffler 10 of the embodiment of the invention, the oil retainer 200 is arranged on the periphery of the oil leakage hole 110, so that the refrigerator oil adhered to the outer wall of the housing 100 of the muffler 10 can be isolated from the oil leakage hole 110, the phenomenon that the returned refrigerator oil is sucked into the muffler 10 through the oil leakage hole 110 is effectively improved, and the oil discharge amount of the compressor is reduced. In addition, the radial area of the oil slinger 200 increases in a direction away from the casing 100, and the distance between the wall surface of the oil slinger 200 and the oil leakage hole 100 increases, thereby increasing the resistance of the refrigerator oil adhered to the outer wall of the casing 100 of the muffler 10 to enter the oil leakage hole 110, further reducing the possibility that the refrigerator oil is sucked into the muffler 10, greatly reducing the oil discharge amount of the compressor, and improving the safety and reliability of the compressor.
The slinger 200 is provided on the bottom wall of the housing 100 at the outer periphery of the oil leakage hole 110, it being understood that the slinger 200 may be spaced apart from the oil leakage hole 110, i.e., the slinger 200 may be spaced apart from the oil leakage hole 110 by a distance. This can increase the distance between the outer wall surface of the slinger 200 and the oil leakage hole 110, and better prevent the refrigerating machine oil adhering to the outer wall surface of the slinger 200 from being sucked into the inside of the casing 100 at the time of back flow. The slinger 200 may be detachably connected to the housing 100, or the slinger 200 may be welded to the housing 100, or the slinger 200 may be integrally connected to the housing 100.
Referring to fig. 1, in one embodiment, oil slinger 200 is detachably connected to housing 100. For example, an annular screw post 120 is provided on the outer periphery of the oil leakage hole 110 in the bottom wall of the casing 100, and a screw thread that mates with the screw post 120 is provided on the inner wall of one end of the slinger 200. For another example, an annular convex edge is disposed on the periphery of the oil leakage hole 110 of the bottom wall of the casing 100, an annular groove is disposed on the outer wall surface of the convex edge, and an annular rib engaged with the annular groove is disposed on the inner wall of one end of the oil retainer 200. By designing the oil slinger 200 and the shell 100 in a detachable connection manner, different oil slingers 200 and the silencer 1 shell can be conveniently selected for installation according to compressors of different models and sizes, thereby increasing the versatility of the suction silencer 10.
In a specific use process of the suction muffler 10 according to the embodiment of the present invention, the bottom wall of the housing 100 is close to the bottom oil pool of the compressor, and the direction away from the housing 100 is also understood as the gravity direction. Referring to fig. 2 and 3, the radial area of the oil slinger 200 increases in a direction away from the housing 100, and it will be appreciated that the radial area of the portion of the oil slinger 200 that is connected to the housing 100 may be designed to be smaller and adapted to the size of the bottom wall of the housing 100 of the muffler 10, facilitating the connection of the oil slinger 200 to the housing 100 and avoiding the oil slinger 200 protruding radially from the housing 100 and being detrimental to the downward fall of refrigerator oil into the bottom sump of the compressor. For example, the outer diameter of the portion where the slinger 200 is connected to the housing 100 is made slightly smaller than the width of the bottom wall of the housing 100 so that the oil of the outer wall of the housing 100 can smoothly flow down. While the radial area of the portion of the slinger 200 remote from the housing 100 can be designed to be relatively large, without being limited by the size of the bottom wall of the housing 100. By increasing the radial area of the slinger 200, the distance between the portion of the slinger 200 and the oil spill hole 110 can be increased, thereby increasing the resistance of the refrigerator oil adhering to the muffler shell outer wall from entering the oil spill hole 110.
As an embodiment, the radial area of the slinger 200 may be locally increased in a direction away from the housing 100. The locally increased means that at least a part of the oil slinger 200 has a larger radial area than the rest in a direction away from the housing 100. Referring to fig. 2, 5 and 6, in one embodiment, the oil slinger 200 includes a first ring body 210 and a second ring body 220 coaxially disposed, one end of the first ring body 210 being connected to the housing 100, and the other end being connected to the second ring body 220. The first ring 210 and the second ring 220 are both in a straight cylindrical shape, and the radial area of the first ring 210 is smaller than the radial area of the second ring 220. In the present embodiment, the radial area of the first ring body 210 close to the housing 100 is smaller than the radial area of the second ring body 220 far from the housing 100, and the radial area of the second ring body 220 is increased relative to the radial area of the first ring body 210. The distance between the side wall of the second ring 220 and the oil leakage hole 110 is increased, thereby increasing the resistance of the refrigerator oil adhered to the outer wall of the muffler case to enter the oil leakage hole 110.
The first ring body 210 and the second ring body 220 are connected to each other by an annular first connection surface 230. It will be appreciated that the first connection surface 230 may be disposed perpendicularly with respect to the central axis of the first ring body 210, as shown in fig. 5. By the design, the oil retainer 200 can be more compact in structure, and has the same radial dimension, and the axial length of the oil retainer 200 is smaller.
Alternatively, as shown in fig. 6, the first connection surface 230 may be disposed obliquely with respect to the central axis of the first ring body 210. The first ring body 210 and the second ring body 220 are connected by the inclined first connecting surface 230, so that the refrigerating machine oil on the outer wall surface of the oil retainer 200 can flow down along the oil retainer 200, and the refrigerating machine oil can flow back to the oil pool at the bottom of the compressor.
It will be appreciated that the axial length of the first ring 210 may be designed to be relatively small, as long as the first ring 210 ensures a reliable connection with the housing 100. For example, when the slinger 200 is screwed to the housing 100, the axial length of the first ring body 210 is designed according to the mating thread length, provided that a secure connection to the housing 100 is achieved. And the axial length of the second ring body 220 may be determined according to the internal space of the compressor. The axial length of the entire oil slinger 200 can be controlled within a moderate range to effectively block the refrigerator oil from being sucked into the muffler 10 while saving costs and reducing occupied space.
Referring to fig. 7 and 8, in another embodiment, the oil slinger 200 includes a third ring 240 and a fourth ring 250 which are coaxially disposed, one end of the third ring 240 being connected to the housing 100, and the other end being connected to the fourth ring 250. The third ring 240 has a straight cylindrical shape, the fourth ring 250 has a horn shape, and the radial area of the fourth ring 250 gradually increases in a direction away from the third ring 240. In this embodiment, the radial area of the fourth ring 250 gradually increases in the direction away from the third ring 240, so that the distance between the sidewall of the fourth ring 250 and the oil leakage hole 110 gradually increases, and the resistance of the refrigerator oil adhered to the outer wall of the muffler shell entering the oil leakage hole 110 gradually increases in the gravity direction, so as to effectively prevent the refrigerator oil from being sucked into the muffler 10.
It is understood that the third ring 240 and the fourth ring 250 may be directly connected, that is, the end surface area of the fourth ring 250 connected to the third ring 240 is equal to the radial area of the third ring 240, and the two may be directly aligned. Alternatively, as shown in fig. 8, the end surface area of the fourth ring 250 connected to the third ring 240 is larger than the radial area of the third ring 240, and the fourth ring 250 is connected to the third ring 240 through the annular second connection surface 260.
It will be appreciated that the axial length of the third ring 240 may be designed to be relatively small, as long as the third ring 240 ensures a secure connection with the housing 100. For example, when the slinger 200 is screwed to the housing 100, the axial length of the third ring body 240 is designed according to the mating thread length, provided that a secure connection with the housing 100 is achieved. And the axial length of the fourth ring body 250 may be determined according to the internal space of the compressor. The axial length of the entire oil slinger 200 can be controlled within a moderate range to effectively block the refrigerator oil from being sucked into the muffler 10 while saving costs and reducing occupied space.
Referring to fig. 9, as another embodiment, the radial area of the slinger 200 increases gradually in a direction away from the housing 100. In this way, the interval between the oil slinger 200 and the oil leakage hole 110 is gradually increased along the gravity direction, so that the resistance of the refrigerator oil adhered to the outer wall of the muffler shell entering the oil leakage hole 110 is gradually increased, thereby effectively preventing the refrigerator oil from being sucked into the muffler 10.
Referring to fig. 4, as an embodiment, the end surface of the slinger 200 remote from the housing 100 is disposed obliquely with respect to the center axis of the slinger 200. By providing the end surface of the slinger 200 remote from the housing 100 as an inclined surface, the falling of the refrigerator oil is facilitated, and the backflow of the refrigerator oil to the bottom oil pool of the compressor is facilitated.
An embodiment of the present invention also provides a compressor including the suction muffler 10 of any of the above embodiments. Since the suction muffler 10 has the above-described advantageous effects, the compressor also has corresponding advantageous effects, and will not be described again.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
