The

  FIG. 3 is a partial perspective view showing the inside of the machine room of the refrigerator according to the embodiment of the present invention, and FIG. 4 is a perspective view showing structures of a water supply pump and a valve according to the embodiment of the present invention.

  As shown in FIGS. 3 and 4, a machine room 140 is formed in the lower part of the cabinet 100. The machine room 140 can form a space in which various configurations such as a compressor 141, a condenser 142, a capillary tube, a fan motor assembly 143, a drain pan 144, and the like constituting a refrigeration cycle are provided.

  The machine room 140 is formed as a separate space separated from the storage space in the cabinet on the lower rear side surface of the cabinet 100 and is formed to open rearward. The opened rear surface of the machine room 140 can be shielded by the machine room cover 145.

  A pump 600 and a valve 700 are provided inside the machine room 140. The pump 600 and the valve 700 are integrally connected by a mounting member 800 and can be fixedly mounted inside the machine room 140 by the mounting member 800.

  More specifically, the valve 700 is mounted on the left side (in FIG. 4) of the mounting member 800, and the pump 600 is mounted on the right side of the mounting member 800, and the whole is formed in one assembly form.

  A mounting portion 810 that is fixedly mounted on one side of the machine room 140 by a fastening member such as a screw is formed on one side of the mounting member 800. The position and shape of the mounting portion 810 can be variously formed according to the mounting position inside the machine room 140.

  The mounting member 800 is formed such that the valve 700 and the pump 600 are mounted in parallel at the same height, and the valve 700 may be positioned above the pump 600 as necessary.

  The valve 700 and the pump 600 are mounted on the mounting member 800 and are adjacent to each other, and water discharged from the pump 600 is supplied to the valve 700 via an output flow path 530 described later.

  Hereinafter, the connection state of the water supply channel 500, the pump 600, and the valve 700 will be described in more detail.

  First, the water supply channel 500 is connected to the pump 600 and the valve 700 so that the water in the water supply container 400 is supplied to the ice maker 310 and the dispenser 212.

  Specifically, the input flow path 520 is connected to the inlet side 610 of the pump 600 into which the water in the water supply container 400 flows. The input flow path 520 is generally composed of an input side extending pipe 522 and an input side connecting pipe 524.

  The input side extension tube 522 is formed of a soft polyethylene material, and can have an inner diameter of about 5/16 inch (2.54 cm). The input side extension pipe 522 extends from the suction flow path 510 to one side adjacent to the pump 600 and is connected to the inlet side 610 of the pump 600 by the input side connection pipe 524.

  The input-side connecting pipe 524 can be formed of a silicon material that also has elasticity, for connecting the inlet side 610 of the pump 600 and the input-side extension pipe 522. By making the end of the input side extension pipe 522 and the inlet side 610 of the pump 600 lie on the same straight line by the input side connection pipe 524, the input side connection pipe 524 is prevented from breaking and clogging the flow path. be able to.

  The inlet side 610 of the pump 600 connected to the input side connecting pipe 524 may have an inner diameter of 1/4 inch (0.635 cm). Since the input side connecting pipe 524 is formed of a soft material, even if the inner diameter of the input side extension pipe 522 and the inner diameter of the inlet side 610 of the pump 600 are different, these can be easily connected.

  Alternatively, the inlet side 610 and the input side extension pipe 522 of the pump 600 having different diameters can be connected by making both end portions of the input side connecting pipe 524 have different inner diameters. Specifically, the input side connecting pipe 524 can be formed to have a step in a direction in which the inner diameter increases from one end to the other end, or in a form in which the cross section expands.

  On the other hand, the output flow path 530 connects the outlet side 620 of the pump 600 and the inlet side 710 of the valve 700, and includes an output side extending pipe 532 and an output side connecting pipe 534. Is done. The output side extension tube 532 can be formed of a soft polyethylene material in the same manner as the input side extension tube 522. The output side extension pipe 532 extends from the valve inlet side 710 to one side of the pump 600 and is connected to the outlet side 620 of the pump 600 by the output side connection pipe 534.

  The output side connection pipe 534 can be formed of the same material as the input side connection pipe 522 and fluidly connects the outlet side 620 of the pump 600 and the end of the output side extension pipe 532. And it is preferable that the output side connection pipe 534 is formed only in the straight section, so that the internal flow path is not clogged by being bent or bent.

  On the other hand, the pump outlet side 620, the output side connecting pipe 534, and the output side extension pipe 532 can all be formed to have an inner diameter of 1/4 inch (0.635 cm). That is, the inner diameter of the input channel 520 can be formed larger than the output channel 530. Accordingly, it is possible to minimize the pulsating flow generated because the amount of water sucked into the pump 600 is smaller than the amount of water discharged from the pump 600.

  In addition, since the input side connection pipe 524 and the discharge side connection pipe 534 can be elastically deformed at the moment when the water is sucked and discharged by the pump 600, it is possible to minimize noise that may be generated when the pipe line contracts or expands.

  On the other hand, the ice maker side flow path 540 connected to the ice maker 310 on the first discharge side 720 of the valve 700 may be formed of polyethylene material and have an inner diameter of 1/4 inch (0.635 cm). The dispenser-side flow path 550 connected to the dispenser 212 on the second discharge side 730 of the valve 700 may be formed of a polyethylene material and have an inner diameter of 5/16 inch (0.794 cm).

  Accordingly, when the dispenser 212 is operated, since the amount of drinking water taken out through the dispenser 212 is larger than the amount of ice-making water supplied to the ice maker 310 side, the drinking water can be quickly taken out.

  Below, operation | movement of the refrigerator by this invention which has the above structures is demonstrated.

  First, in order to use ice-making water and drinking water, the water supply container 400 is filled with water, and the container connecting part 222 and the water supply container 400 are coupled. Thereafter, the water supply container 400 is attached to the back surface of the refrigerator compartment door 220. As the water supply container 400, a bottle containing water can also be used. In this case, a commercially available bottle containing water can be opened and attached to the container connecting portion 222 without a separate water supply process.

  The suction channel 510 is positioned inside the water supply container 400 by the coupling of the water supply container 400 and the container connecting portion 222, and the water inside the water supply container 400 can be sucked. By attaching the container connecting portion 222, the suction flow path 510 is communicated with the input flow path 520, and water can be supplied to the ice maker 310 and the dispenser 212.

  In such a state, when a water supply signal to the ice maker 310 is transmitted to the control unit for ice making, or a drinking water take-out command is transmitted to the control unit by an input button provided in the dispenser 212, the pump 600 is driven.

  When the pump 600 is driven, water inside the water supply container 400 is sucked into the suction flow path 510 and is sucked into the pump 600 through the input flow path 520. That is, the water sucked into the suction channel 510 is supplied to the pump 600 through the input side extension pipe 522, the input side connection pipe 524, and the inlet side 610 of the pump 600 in order.

  At this time, the input side connecting pipe 524 expands or contracts in the radial direction due to the pulsating flow that may occur when the pump 600 is driven. Such expansion or contraction alleviates the impact of the pipeline, and as a result, noise in the pipeline is reduced. The pulsation can be reduced by supplying a sufficient amount of water to the inside of the pump 600.

  Then, water discharged from the pump 600 through the output flow path 530 is guided to the valve 700. At this time, water discharged from the pump 600 is supplied to the valve 700 through the outlet side 620 of the pump 600, the output side connecting pipe 534, and the output side extension pipe 532 in order. The pulsating flow phenomenon generated by the water discharged from the pump 600 can reduce the noise of the pipe line by the flexibility of the output side connecting pipe 534.

  The water supplied to the valve 700 is supplied to the ice maker 310 via the ice maker side flow path 540 when the ice making water supply signal is commanded, the first discharge side 720 of the valve 700 is opened.

  And when the supply signal for taking out drinking water is commanded, the 2nd outlet side 620 is opened, it is supplied to dispenser 212 via dispenser side channel 550, and it becomes possible to take out drinking water. .

  On the other hand, when the water stored in the water supply container 400 is depleted and the water supply container 400 is empty while the refrigerator 1 is being driven, when the pump 600 is driven, air and water are placed on the water supply channel 500. Are mixed and the state shown in FIG. 5 is obtained.

  5 and 6 are diagrams schematically illustrating a water supply state of the refrigerator according to the embodiment of the present invention.

  In FIG. 5, for convenience of explanation, a structure in which water is supplied to an ice maker will be described as an example.

  As shown in FIG. 5, before the water in the water supply container 400 is completely depleted, the water supply channel 500 is filled with water, and when the pump 600 is driven, the pressure on the inlet side 610 and the outlet side 620 of the pump 600 is increased. Due to the difference, water is supplied to the ice maker 310.

  On the other hand, when the pump 600 is driven by the operation signal of the ice maker 310 after the water in the water supply container 400 is completely depleted, water and air coexist in the water supply channel 500, and the inlet of the pump 600 Air is drawn from side 610.

  Specifically, when the pump 600 is driven while the water supply container 400 is empty, the air in the water supply container 400 flows into the pump 600 via the suction flow path 510 and the input flow path 520. Then, the air that has flowed into the pump 600 is discharged toward the output flow path 530. The air discharged to the output flow path 530 flows into the valve 700 through the output flow path 530 and is supplied to the ice maker side flow path 540.

  Therefore, a part of the suction flow path 510, the input flow path 520, the output flow path 530, and the ice maker side flow path 540 is filled with air.

  In such a state, even if the water supply container 400 is filled with water and reattached, the pump 600 cannot sufficiently generate pressure for discharging the residual water in the ice maker side flow path 540. That is, if air exists on both the inlet side 610 and the outlet side 620 of the pump 600, the water supply condition becomes poor, and the pump 600 cannot generate pressure that can smoothly supply water.

  In order to cancel such a bad water supply condition, when an operation signal of the ice maker 310 is input, the pump 600 is operated simultaneously with the opening of the valve 700.

  On the other hand, the valve 700 and the pump 600 are located below the water supply container 400 as well as the water utilization device 250, and the valve 700 and the pump 600 maintain a connected state at positions adjacent to each other.

  The valve 700 is located at the same or higher position as the pump 600, and at the moment when the valve 700 is opened, the water remaining in the ice maker side channel 540 passes through the valve 700 as shown in FIG. It flows into the outlet side of 600.

  That is, due to the position of the valve 700 and the pump 600 and the structure of the water supply channel 500, water flows into the pump 600 when the valve 700 is opened. Accordingly, both the inside of the pump 600 and the inlet side 610 and the outlet side 620 of the pump 600 are filled with water in a short time.

  Thus, since water is supplied to the pump 600 side when the valve 700 is opened due to the mounting position of the water utilization device 250, the water supply container 400 and the pump 600, that is, the height difference, the water supply condition on the water supply channel 500 is A bad state can be quickly removed. Accordingly, the pump 600 can generate a normal discharge pressure, discharge the residual water in the ice maker side flow path 540, and smoothly supply water continuously supplied from the water supply container 400. .

  It should be understood by those skilled in the art that such a principle can be applied not only to the ice maker side channel 540 but also to the dispenser side channel 550.
