Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
The words for expressing the position and direction described in the present invention are all referred to when the refrigerator is in an upright state, the extending direction between the door and the back panel is the front-rear direction, and the extending direction between the left side panel and the right side panel is the left-right direction. The piping is proximal in the direction toward the compressor and distal in the direction away from the compressor toward the evaporator.
In the embodiment of the present invention, the present invention is specifically explained by taking a refrigerator as an example, but it should be noted that the technical spirit involved in the embodiments described below may be alternatively utilized to other forms of refrigeration apparatuses, such as a refrigerator exemplarily.
The refrigerator of the invention comprises a refrigerator body, a plurality of refrigerating compartments are limited in the refrigerator body; a door formed in the front of the box body and capable of pivoting around a shaft to open and close the refrigerating compartment; a foaming layer for coating the box body to insulate heat; the refrigerating system comprises a compressor, a condenser, an evaporator and the like. Wherein, the box top rear side forms one and holds chamber (press storehouse), and it encloses to close by end steel and backplate, roof and forms, and the compressor is held in this cavity. The evaporator is arranged below the compressor.
one end of the tubing is connected with the evaporator, and the other end of the tubing is connected with the compressor through a connecting pipe. An oil outflow prevention mechanism is provided at one end of the pipe close to the compressor. When the refrigerator is dumped, the highest point of the oil outflow prevention mechanism is always higher than the oil level height in the compressor, when the refrigerator is recovered to a vertical state, the compressor oil can flow back to the compressor under the action of gravity, and the compressor generates enough negative pressure to prevent a small amount of residual oil in the oil outflow mechanism from being sucked into the compressor by combining with the adjustment of the rotating speed of the compressor during starting, so that the compressor oil is prevented from flowing back to the evaporator when the refrigerator is dumped.
Specifically, the oil outflow prevention mechanism is a pipe having a plurality of bent portions, on which the valve body can be selectively disposed. The oil outflow prevention mechanism includes a bent portion extending in the front-rear direction and a bent portion extending in the left-right direction.
The bending part extending in the front-back direction is bent in a vertical plane or a plane close to the vertical plane, and part or all of the bending part is positioned in the foaming layer so as to reduce the arrangement of pipelines in the pressing machine bin. The front end of the bent part is closer to the front part than the center line of the compressor in the front-back direction, and when the refrigerator topples backwards, the highest point of the bent part is always higher than the oil level in the compressor.
The bent portion extending in the left-right direction is also bent in a vertical or nearly vertical plane and crosses the center line of the compressor in the left-right direction. When the refrigerator is inclined leftwards or rightwards, the highest point of the bent part is always higher than the oil level in the compressor.
the following describes the technical aspects of the present invention with reference to specific embodiments. The present invention is not limited to these embodiments.
Example 1
Referring to fig. 1 and 2, the proximal end of the tubing 10 is connected to the connecting tube 20, passes through the bottom steel from the front wall 301 of the press chamber into the foam layer, and extends toward the evaporator at the lower portion of the compressor 40.
The connection pipe 20 is located at one side of the back surface of the lower casing of the compressor 40, and the pipe 10 extends downward from the connection pipe 20 to form a vertical portion 101, and then horizontally extends in a left-right direction vertical plane to the opposite other side of the back surface of the compressor 40 and forms a U-shaped bent portion 103.
The U-shaped bent portion 103 includes parallel horizontal portions 103a and 103b and an end portion 103 c. Wherein the end portion 103c exceeds the center line of the compressor 40 in the left-right direction with respect to the vertical portion 101. The end 103c is arranged such that the oil level in the compressor 40 is always lower than the highest point of the U-turn 103 when the refrigerator is tilted to the side where the connection pipe 20 is located.
The horizontal portion 103b is higher than the top of the connection tube 20, and has a distal end connected to the U-shaped bent portion 105 and a proximal end connected to the end portion 103 c. Preferably, the horizontal portion 103b has a small downward slope from the distal end to the proximal end so that the compressor oil contained therein flows back toward the compressor 40 by gravity. The oil at the near end of the pipe 10 cannot completely flow back to the compressor only by gravity, and the compressor can be started at a high rotation speed, and the compressor oil at the near end of the pipe, such as the horizontal part 103a, the vertical part 101 and the connecting pipe 20, can be sucked into the compressor by negative pressure at the starting moment.
The U-shaped bent portion 105 extends on a front-rear direction vertical plane, and includes horizontal portions 105a and 105b and an end portion 105 c. The horizontal part 105a extends from the horizontal part 103b to the front wall 301 of the press chamber, and penetrates through the bottom steel to enter the foaming layer, and the far end of the horizontal part 105a is connected with the end part 105 c. The end portion 105c extends vertically downward within the foamed layer, and its distal end is connected to the horizontal portion 105 b. The horizontal portion 105b extends rearward in the foam layer under the bottom plate of the cabinet to the back of the refrigerator and then bends toward the evaporator. The U-bend 105 is arranged so that its front end is closer to the front than the front end of the compressor, and when the refrigerator is tilted backward, the oil level in the compressor is always lower than the highest point of the U-bend 105.
The U-shaped bend may be replaced by other shaped bends, such as V-shaped, S-shaped, etc.

Referring to fig. 3 and 4, the proximal end of the tubing 60 is connected to the compressor 40 via the connecting tube 20, and the distal end thereof passes out of the bottom plate 303 of the press chamber into the foam layer.
The connection pipe 20 is located at one side of the rear surface of the lower case of the compressor 40, and the piping 60 extends downward from the connection pipe 20 to form a vertical portion 601, and then horizontally extends in a left-right direction vertical plane to the opposite side of the rear surface of the compressor 40 and forms a U-shaped bent portion 603.
The U-shaped bent portion 603 is substantially the same as the U-shaped bent portion 103 shown in fig. 1 and 2, so that when the refrigerator is tilted to the side where the connection pipe 20 is located, the oil level in the compressor 40 is always lower than the highest point of the U-shaped bent portion 603. The difference is that the distal end of the U-bend 603 extends downward, out through the bottom steel from the bottom plate 303 of the press bin, and connects to the U-bend 605.
the U-shaped bent portion 605 is located in the foamed layer, extends in the front-rear direction on a horizontal plane, and includes a horizontal portion 605a, an end portion 605c, and a horizontal portion 605b in this order from the proximal end to the distal end. The distal end of the horizontal portion 605b is bent toward the evaporator and extends. The end 605c is located forward of the center line of the compressor in the front-rear direction, and when the refrigerator is tilted backward, the oil level in the compressor is always lower than the highest point of the U-shaped bent portion 605.
Example 3
Referring to fig. 5 and 6, the proximal end of the tubing 70 is connected to the compressor 40 via the connecting tube 20, and the distal end thereof passes out of the side wall 305 of the press chamber and into the foam layer.
The connection pipe 20 is located at one side of the rear surface of the lower casing of the compressor 40, and the piping 70 extends downward from the connection pipe 20 to form a vertical portion 701, and then horizontally extends in a left-right direction vertical plane to the opposite other side of the rear surface of the compressor 40 and forms a U-shaped bent portion 703.
The U-shaped bent portion 703 is substantially the same as the U-shaped bent portion 703 shown in fig. 1 and 2, so that when the refrigerator is tilted to the side where the connection pipe 20 is located, the oil level in the compressor 40 is always lower than the highest point of the U-shaped bent portion 703. The difference is that the distal end of the U-bend 703 extends downward and forward of the press silo, passes out of the bottom steel from the side wall 305 of the press silo, and connects to the bend 705.
The bent portion 705 is located in the foamed layer and includes, in order from the proximal end to the distal end, a vertical portion 705a, horizontal portions 705b, 705 c. The vertical portion 705a is substantially perpendicular to the plane of the horizontal portions 705b, 705 c. The horizontal portion 705b extends in the left-right direction and is located forward of the center line of the compressor in the front-rear direction, and when the refrigerator is tilted backward, the oil level in the compressor is always lower than the highest point of the bent portion 705. The horizontal portion 705c is substantially perpendicular to the horizontal portion 705b and extends toward the back of the refrigerator.

Referring to fig. 7, the proximal end of tubing 80 is connected to compressor 40 via connecting tube 20, and the distal end passes out of the platen front wall 301 through the base steel into the foam layer. The pipe 80 is extended out from the connection pipe 20 on the same side in the left-right direction of the compressor.
The connection pipe 20 is located at one side of the back surface of the lower case of the compressor 40.
The piping 80 extends toward the front wall 301 and enters the foamed layer to form a bent portion 805, and the bent portion 805 extends on a front-rear direction vertical plane, and has the same structure as the U-shaped bent portion 105 shown in fig. 1 and 2, so that the front end thereof is located forward of the front end of the compressor, and when the refrigerator is tilted backward, the oil level in the compressor is always lower than the highest point of the U-shaped bent portion 805. The top of the bend 805 is higher than the top of the connection tube 20 to allow oil at the proximal end of the tubing 80 to flow back toward the compressor 40 under the force of gravity.
Wherein the distal end of the curved portion 805 extends rearward in the foam layer at the bottom of the cabinet to the back of the refrigerator, and then extends horizontally along the opposite side horizontally facing the back of the compressor 40 and forms a U-shaped curved portion 807. The bent portion 805 is located further toward the rear of the refrigerator than the front-rear center line of the compressor 40. The end 807c of the bent portion 807 exceeds the center line of the compressor 40 in the left-right direction so that the oil level in the compressor 40 is always lower than the highest point of the bent portion 807 when the refrigerator is tilted to the side where the connection pipe 20 is located. The bend 807 is disposed within the foam layer to further free the press chamber.
The tubing 80 may be formed as shown in fig. 7 with a U-bend 803 in the press silo, the distal end of which is connected to 805. The U-shaped bent portion 803 is similar to the U-shaped bent portion 103 shown in fig. 1 and 2.
