Description

  The present invention relates to an ice making machine having an accumulator in a refrigeration circuit.

  For example, as shown in FIG. 6, an ice-type ice making mechanism 30 that continuously produces ice blocks by supplying ice-making water from a water dish 34 to a large number of ice-making chambers that open downward in the ice-making room 32. The ice making machine 11 equipped with is widely put into practice. The ice making machine 11 has a box 12 as a main body, which is divided into left and right by a partition wall 14 and has one of the heat insulation structures as an ice storage chamber 12a, and the other as a compressor, a condenser, a cooling fan, The machine room 12b is provided with an expansion valve, a control device, and the like (see FIG. 7). The ice making mechanism 30 is attached below the mechanism frame 28 installed between the side wall 16 and the partition wall 14 of the box 12 and is installed at the upper part of the ice storage chamber 12a, and the ice mass produced by the ice making mechanism 30 drops. Thus, it is stored in the ice storage chamber 12a. In addition, the ice making mechanism 30 includes part of a refrigeration circuit, and includes an evaporator EP that cools the ice making chamber 32 and a water supply unit 40 that is connected to an external water source and supplies ice making water to the water tray 34. In the refrigeration circuit, the vaporized refrigerant compressed by the compressor is deprived of heat by the condenser to be condensed and liquefied, and the liquefied refrigerant whose pressure has been reduced by the expansion valve is expanded and vaporized by the evaporator EP. The ice making chamber 32 is cooled by removing the heat of 32. In the refrigeration circuit, the vaporized refrigerant returns from the evaporator EP to the compressor, and the refrigerant circulates in the circuit.

  The refrigeration circuit is provided with an accumulator 50 on the return path from the evaporator EP to the compressor (see FIG. 7), and the refrigerant returning from the evaporator EP to the compressor is gas-liquid separated, thereby compressing only the vaporized refrigerant. The refrigerant is returned to the compressor to prevent the refrigerant from getting stuck in the compressor (see, for example, Patent Document 1). The accumulator 50 is disposed in the ice storage chamber 12a so as to incline upward from the connection end on the evaporator EP side toward the connection end on the compressor side. Thus, the accumulator 50 is installed so that the outlet on the compressor side is higher than the inlet on the evaporator side, thereby preventing the liquefied refrigerant from flowing out to the compressor side.

Has been established. The accumulator 50 is fixed by inserting and fastening the binding band 94 holding the refrigerant pipe 52 on the evaporator EP side through the upper and lower through holes 92 and 92. As described above, the support structure for the accumulator 50 shown in FIG. 7 requires a dedicated support member 90 and takes time and effort to weld the support member 90 to the mechanism frame 28. That is, in the ice making machine 11, the number of parts is increased by the amount of the support member 90 in order to attach the accumulator 50, and the number of steps is increased because a separate work is required to attach the support member 90 itself.

  As shown in FIG. 4, the refrigeration circuit 48 is configured by connecting a compressor CM, a condenser CD cooled by a cooling fan FM, an expansion valve EV, an evaporation pipe EP, and an accumulator 50 through a refrigerant pipe 52. . In the refrigeration circuit 48, the vaporized refrigerant compressed by the compressor CM is condensed and liquefied by the condenser CD, and then the refrigerant decompressed by the expansion valve EV flows into the evaporation pipe EP, where it is expanded and evaporated, and the evaporator EP The vaporized refrigerant separated from the liquid via the accumulator 50 is returned to the compressor CM. The refrigeration circuit 48 includes a bypass circuit that directly supplies refrigerant (hot gas) from the compressor CM to the evaporation pipe EP without passing through the condenser CD and the expansion valve EV during the deicing operation (see FIG. 4). This bypass circuit includes a bypass pipe 54 that connects the discharge side of the compressor CM and the suction side of the evaporation pipe EP, and a hot gas valve HV that is disposed in the middle of the bypass pipe 54 and controlled to be opened and closed by the control means.

  In the ice making machine 10, the refrigerant pipe 52 connected from the expansion valve EV installed in the machine room 12 b to the evaporator EP installed in the ice storage room 12 a passes through the recess 14 a of the partition wall 14 to store ice from the machine room 12 b. It enters the chamber 12 a, passes below the mechanism frame 28 between the partition wall 14 and the ice making mechanism 30, and is connected to the evaporator EP from the front side of the ice making mechanism 30. Further, in the ice making machine 10, the accumulator 50 is disposed between the ice making mechanism 30 and the rear wall 17 in the ice storage chamber 12a. An evaporator EP-side refrigerant pipe connected to the accumulator 50 from the evaporator EP (in particular, an inflow-side refrigerant pipe 52A) is a mechanism frame between the partition wall 14 and the ice making mechanism 30 from the front side of the ice making mechanism 30. 28 extends between the ice making mechanism 30 and the rear wall 17 through the lower part of the ice 28 and extends in the left direction away from the partition wall 14 along the water supply pipe 42 extending between the ice making mechanism 30 and the rear wall 17. Exist. The inflow-side refrigerant pipe 52A is bent downward on the left side of the ice storage chamber 12a, and further, a portion bent rightward toward the partition wall 14 is connected to the accumulator 50. On the other hand, the refrigerant pipe on the compressor CM side connected to the compressor CM from the accumulator 50 (referred to as the outflow-side refrigerant pipe 52B in particular) is passed between the ice making mechanism 30 and the rear wall 17 to form the partition wall 14. The machine room 12b is entered from the ice storage room 12a via the recess 14a.

  In the box 12, the recess 14 a of the partition wall 14 is closed with a heat insulating member 26 made of a foamed material such as urethane formed in accordance with the recess 14 a (see FIG. 1). The heat insulating member is provided with a notch 26a that opens downward, and a water supply pipe 42, a refrigerant pipe 52, an electric wire, and the like inserted through the recess 14a are passed through the notch 26a to hold these pipes and the like. .

  In the accumulator 50, the inflow refrigerant pipe 52A on the evaporator EP side is fixed to the water supply pipe 42, and the outflow refrigerant pipe 52B on the compressor CM side is held by the heat insulating member 26 of the partition wall 14, so that the evaporator It is installed in an inclined posture that inclines upward from the connection end on the EP side toward the connection end on the compressor CM side (see FIG. 2). In addition, the accumulator 50 is fixed below the water supply pipe 42 so that the whole is accommodated above the lower end of the ice making mechanism 30 below the mechanism frame 28. More specifically, the accumulator 50 has a portion extending in the left-right direction between the ice making mechanism 30 and the rear wall 17 in the inflow-side refrigerant pipe 52 </ b> A, and the left-right direction between the ice making mechanism 30 and the rear wall 17. The evaporator EP side is supported in a suspended state by an inflow side refrigerant pipe 52 </ b> A fixed to the water supply pipe 42. It should be noted that a heat insulating material (not shown) such as a foam such as urethane is interposed at a contact portion between the inflow side refrigerant pipe 52A and the water supply pipe 42, and the water supply pipe 42 is formed by the inflow side refrigerant pipe 52A having a low temperature. Is prevented from freezing, and the generation of noise due to direct contact between the inflow-side refrigerant pipe 52A and the water supply pipe 42 is prevented.

  As the binding band 56, a head having an insertion hole and a claw projecting into the insertion hole is provided at one end, and the other end is inserted into the insertion hole of the head, so that a plurality of the binding bands 56 are provided apart from each other in the longitudinal direction. A so-called cable tie or an insulation lock in which the protrusion is locked by the claw and prevented from coming off is preferably used, but a wire or other string-like object can be used.

  The accumulator 50 has a hollow cylindrical body 50a as a main body, the inflow side refrigerant pipe 52A is inserted into the cylindrical body 50a from the inclined lower end of the cylindrical body 50a, and the inflow side refrigerant pipe 52A has an inlet. It faces the inside of the cylindrical body 50a (see FIG. 2). Further, in the accumulator 50, the outflow side refrigerant pipe 52B is connected to the inclined upper end of the cylindrical body 50a. In the accumulator 50, the insertion end of the inflow side refrigerant pipe 52A inserted into the cylindrical body 50a is bent upward from the inclined axis of the cylindrical body 50a, and the inflow port is in the inflow side refrigerant pipe 52A. Is shifted upward from the line connecting the connection portion of the refrigerant and the connection portion of the outflow side refrigerant pipe 52B.

(Effects of Example)
Next, the operation of the ice making machine according to the embodiment will be described. In the ice making machine 10, in the ice making operation, the refrigerant expanded and vaporized in the evaporator EP flows into the accumulator 50 via the inflow side refrigerant pipe 52A, and the liquid phase portion contained in the inflowed refrigerant is in the lower inclined portion of the cylindrical body 50a. Only the gas phase portion is stored and returned to the compressor CM via the outflow side refrigerant pipe 52B. Here, since the inflow-side refrigerant pipe 52A protrudes inside the cylindrical body 50a, the accumulator 50 can avoid the liquefied refrigerant staying in the inclined lower portion of the cylindrical body 50a from returning to the inflow-side refrigerant pipe 52A. In the ice making machine 10, in the deicing operation, hot gas (high-temperature / high-pressure vaporized refrigerant) directly supplied from the compressor CM to the evaporator EP flows into the accumulator 50 through the inflow-side refrigerant pipe 52 </ b> A, and the outflow side. The refrigerant is returned to the compressor CM through the refrigerant pipe 52B. In the accumulator 50, the insertion end of the inflow side refrigerant pipe 52A protruding inside the cylindrical body 50a is bent upward and the inlet is directed to the upper surface of the inner wall of the cylindrical body 50a. The hot gas that has flowed into the pipe is guided to the inner surface of the cylindrical body 50a and forms a flow that circulates along the inner surface (see FIG. 2). In the accumulator 50, the temperature of the entire cylindrical body 50a is increased by hot gas, and the liquefied refrigerant staying in the lower inclined portion of the cylindrical body 50a is volatilized and returned to the compressor CM via the outflow side refrigerant pipe 52B. Is done. Thereby, in the refrigeration circuit 48, it is suppressed that a refrigerant | coolant retains excessively in the accumulator 50, and the refrigerant | coolant shortage in this circuit 48 is avoided.

  Since the ice making machine 10 uses the water supply pipe 42 installed in the ice storage chamber 12a and the heat insulating member 26 disposed on the partition wall 14 as a support member for supporting the accumulator 50, a dedicated support member is used. Can be omitted. That is, as described in the conventional example, the trouble of fixing the dedicated support member to the mechanism frame 28 can be omitted. Therefore, according to the ice making machine 10 of the embodiment, the number of parts of the support structure of the accumulator 50 can be reduced, the number of man-hours for attaching the accumulator 50 can be reduced, and the attaching operation can be simplified.

  The water supply pipe 42 is held by a heat insulating member 26 disposed in the recess 14 a of the partition wall 14 and is held by a support tool 60 attached to the mechanism frame 28, and has sufficient strength to support the accumulator 50. have. The accumulator 50 has a configuration in which the evaporator EP side is fixed to the water supply pipe 42 by a binding band 56 and the compressor CM side is held by the heat insulating member 26 of the partition wall 14. Supported on both sides. That is, the accumulator 50 does not change its tilting posture even when vibrations such as when the ice making machine 10 is transported or shocks during refrigerant flow are applied, and the required gas-liquid separation function and the storage capacity of the separated liquefied refrigerant are appropriately set. Can be secured. Further, by using a flexible member as the heat insulating member 26, the heat insulating member 26 can absorb the vibration and the like when a vibration during transportation of the ice making machine 10 or an impact during refrigerant circulation is applied. it can.

  The ice making machine 10 includes devices such as an ice making water pump PM that requires maintenance such as replacement and cleaning, an actuator motor AM of a water tray opening and closing mechanism 38, a water supply valve WV, etc., and an ice making mechanism having a wide opening. 30 on the front side. On the other hand, since the accumulator 50 is less likely to break down and needs less maintenance, there is no particular problem even if it is disposed on the rear side of the ice making mechanism 30. In the ice making machine 10 of the embodiment, the rear side of the ice making mechanism 30 is not problematic. Is effectively used as an installation space for the accumulator 50. In addition, since the accumulator 50 is installed below the mechanism frame 28 so as to extend above the lower end of the ice making mechanism 30, the accumulator 50 does not protrude into the ice storage area of the ice storage chamber 12 a below the ice making mechanism 30. The accumulator 50 does not reduce the ice storage area.

(Example of change)
The present invention is not limited to the configuration of the above-described embodiment, and can be modified as follows.
(1) In the embodiment, a closed cell type ice making mechanism has been described as an example, but an ice making machine having an open cell type or a flow-down type ice making mechanism is also applicable.
(2) The arrangement relationship between the ice storage chamber and the machine room is not limited to the horizontal direction, and may be arranged in a vertical relationship. For example, the machine room is arranged below the ice storage room, and the refrigerant pipe passes through the rear wall of the ice storage room and the rear panel of the machine room, and the refrigerant pipe is inserted between the machine room and the ice storage room. The structure extended along the back surface of this may be sufficient. In this case, the compressor side of the accumulator is supported at the penetration portion in the rear wall of the ice storage chamber. Further, the water supply pipe is provided so as to penetrate the rear wall of the ice storage chamber, and the water supply pipe is supported by a penetration portion of the rear wall.
