  First, the whole structure of a refrigerator is demonstrated. 1, 2, and 3, reference numeral 1 denotes a refrigerator body. The refrigerator main body 1 is divided into an inside and an outside by a heat insulating box body provided with a heat insulating material 4 (for example, a foam heat insulating material, a vacuum heat insulating material, etc.) between the outer box 2 and the inner box 3. A compressor 5 that is a part of the refrigeration cycle is disposed at the lower rear of the refrigerator body 1. As long as the compressor 5 is partitioned from the storage room in an adiabatic manner, the compressor 5 may be located behind the upper portion of the refrigerator body 1 and the installation position thereof is not particularly limited.

  In the refrigerator main body 1, a storage room for a refrigerator compartment 6, an ice making compartment 14, an upper freezer compartment 7 a, a lower freezer compartment 7, and a vegetable compartment 8 is formed. The refrigeration cycle is composed of a compressor 5, a condenser, a capillary tube, a cooler 18, and the like. The refrigerant compressed by the compressor 5 is condensed by a condenser (not shown), and the capillary tube. It evaporates with an evaporator (cooler which will be described later) through a decompression section such as, circulates so as to be returned to the compressor 5 and compressed, and this is repeated. Thereby, the inside of the previous refrigerator compartment 6, the lower freezer compartment 7, and the vegetable compartment 8 is cooled to predetermined temperature.

  A refrigerator compartment door 9 that opens and closes the refrigerator compartment 6, an ice making compartment door that opens and closes the ice compartment 14, a first freezer compartment door 11 that opens and closes the upper freezer compartment, and a lower freezer compartment 7 are opened and closed at the front opening of the refrigerator body 1. A second freezer compartment door 12 and a vegetable compartment door 13 for opening and closing the vegetable compartment 8 are provided.

  Moreover, the refrigerator compartment door 9 is a double door type (French door) connected to the refrigerator main body 1 so that rotation is possible by the hinge 15 etc. which are shown in FIG. The other doors are of a drawer type, and are configured such that when the door is pulled out, the storage container in each storage chamber is pulled out together with the door by a door frame and a rail.

  Reference numeral 16 denotes a cooler chamber. The cooler chamber 16 is configured to be partitioned by a partition member 17 behind the lower freezing chamber 7. A cooler 18 constituting a part of the refrigeration cycle is disposed in the cooler chamber 16. A defrost heater 19 is disposed below the cooler 18 to remove frost attached to the cooler 18, and a blower 20 serves as a cool air circulation means. The blower 19 circulates the cold air exchanged by the cooler 18 to the refrigerator compartment 6, the ice making compartment 14, the upper freezer compartment 7 a, the lower freezer compartment 7, and the vegetable compartment 8. Reference numeral 21 denotes a damper that controls the amount of cool air blown from the blower 20 to each storage room and serves to control each storage room to a preset temperature.

  22 is a heat insulating partition wall that partitions the refrigerator compartment 6 and the freezing temperature zone chamber (the ice making chamber 14, the upper freezing chamber 7a, the lower freezing chamber 7), and 23 is a heat insulation partitioning the freezing temperature zone chamber and the vegetable compartment 8. It is a partition wall. That is, the refrigeration temperature zone chamber and the refrigeration temperature zone chamber having different temperature zones are adiabatically partitioned by the heat insulating partition walls 22 and 23, and the temperature zone has a common refrigeration temperature zone chamber (the ice making chamber 14 and the upper freezer compartment). 7a, the lower freezer compartment 7) is configured such that the front is partitioned so as to receive the seal member of each door, and cool air can flow back and forth.

  Reference numeral 24 denotes a water storage tank provided in the refrigerator compartment 6. The water in the water storage tank 24 is supplied to an ice tray of an automatic ice maker described later by water supply means such as a pump.

  Reference numeral 25 denotes an automatic ice making machine. The automatic ice making machine 25 includes an electric mechanism unit 26 in an ice making frame 29, an ice tray 27 that is rotationally driven by the electric mechanism unit 26, an ice detecting lever 28 that detects the amount of ice in an ice storage container 30 described later, and the like. Is incorporated.

  The ice tray 27 is made of resin and has a long shape in the front-rear direction made of a material that can be twisted, and has four rows, two rows, five rows, or six rows in the longitudinal direction. Are divided into a plurality of cells.

  The ice detecting lever 28 is wide and has an L shape as shown in FIG. 2, and the tip of the ice detecting lever 28 moves in the direction of the arrow a around the fulcrum 28a by the driving force of the electric mechanism 26. Detect the amount of ice.

  As will be described later, the automatic ice making machine 25 has an ice detecting lever 28 on the left side (away from the blower 20) of the refrigerator main body 1 and a cold air passage for cooling the ice tray 27 on the right side of the refrigerator main body 1 (first cold air passage to be described later). 33) is provided. The ice storage container 30 is suspended from the door frame 10 a on the ice making room door 10 side, and is configured to be pulled out together with the ice making room door 10 when the ice making room door 10 is pulled out to the near side.

  The ice making frame 29 constituting the outer shell of the automatic ice making machine 25 is attached to the ice making chamber 14 in association with the partition member 17 as shown in FIGS. That is, the partition member 17 is arranged so as to take in the cold air blown out from the first cold air outlet 31 and the second cold air outlet 32 shown in FIG.

  The ice making frame 29 has a first cold air passage 33, a second cold air passage 34, and a third cold air passage 35, and cools the ice tray 27 and the ice detecting lever 28 and prevents frost formation.

  Specifically, as shown in FIG. 4, the first cold air outlet 31 and the second cold air outlet 32 are arranged on the partition member 17 side by side. The cold air blown out from the first cold air outlet 31 disposed near the center in the left-right direction of the refrigerator body 1 is guided to the first cold air passage 33 (see FIG. 5). The cold air blown out from the second cold air outlet 32 is guided to the second cold air passage 34 and the third cold air passage 35 (see FIGS. 3 and 5).

  The ice making control of the automatic ice making machine 25, the temperature control of the refrigerator compartment 6, the lower freezer compartment 7, the vegetable compartment 8, etc., and other various functions of the refrigerator are controlled by control devices provided in the refrigerator main body 1.

  Next, the cold air passage will be described in more detail. The cold air blown out by the second cold air outlet 32 shown in FIG. 4 is a second cold air passage 34 formed between the ice making frame 29 and the upper wall 14a of the ice making chamber 14 (see FIGS. 3 and 5). The ice detection lever storage chamber 36 is introduced into the third cold air passage 35 through an ice detection lever storage chamber opening 37 provided on the side wall 29d of the ice detection lever storage chamber forming the ice detection lever storage chamber 36. (See FIG. 8). Thereby, the frost attached to the ice detecting lever 28 is sublimated with cold air, and the ice detecting lever 28 is prevented from being erroneously detected due to frost.

  That is, as shown in FIG. 2, the ice detecting lever 28 moves in the direction of arrow a before deicing, detects the amount of ice in the ice storage container 30, and completes the ice in the ice tray 27 into the ice storage container 30. Determine whether to drop. Here, when frost grows on the ice detecting lever 28, the detected height of the ice changes, and the accurate amount of ice cannot be measured. Therefore, the third cold air passage 35 is formed, and cold air is applied to the ice detecting lever 28 so that, for example, frost attached to the ice detecting lever 28 is sublimated when the ice making chamber door 13 is opened and closed.

  The electric mechanism unit 26 is located behind the ice tray 27 and in front of the partition member 17. It is necessary to consider the cold air from the first cold air passage 33 so that the electric mechanism portion 26 does not hinder the flow. Therefore, as shown in FIG. 3, the cold air blown out from the first cold air outlet 31 is the second cold air between the ice making frame 29 (the upper surface of the electric mechanism section 26) and the upper wall 14a of the ice making chamber 14. After passing through the passage 34, the air flows into the upper surface of the ice tray 27 in the ice tray storage chamber 39 from the air holes 29 b formed in the upper surface of the ice frame 29.

  The first cold air passage 33 and the third cold air passage 35 are air passages provided on the ice making frame 29 side. Therefore, it reaches the front of the ice tray 27 (the side opposite to the electric mechanism portion 26 with the ice tray 27). On the other hand, the second cold air passage 34 is located above the ventilation hole 29 b, that is, from the electric mechanism portion 26 when viewed in the longitudinal direction of the ice tray 27.

  Next, the ice making frame 29 that houses the electric mechanism 26, the ice tray 27, etc. will be described with reference to FIGS.

  In FIG. 5, reference numeral 44 denotes a wind direction plate of the second cold air passage. The wind direction plate 44 of the second cold air passage is provided on the upstream side of the second cold air passage 34, the cold air flowing to the air vent 29 b side and guided to the ice tray storage chamber 39, and the third cold air passage 35. To the cold air led to the ice detecting lever storage chamber 36. The amount of cold air is distributed so that the ice tray storage chamber 39 is larger than the ice detecting lever storage chamber 36.

  Here, the overall configuration of the ice making frame 29 will be described. The ice making frame 29 is integrally formed by injection molding of resin. As shown in FIGS. 5 to 10, the ice making frame 29 has a gate-like shape with an open lower surface, and is disposed on the first cold air passage 33 disposed on the side close to the blower 20 and on the side far from the blower 20. The ice detection lever storage chamber 36 and an ice making tray storage chamber 39 disposed between the first cold air passage 33 and the ice detection lever storage chamber 36 are provided. At the rear of the ice tray storage chamber 39, there is an electric mechanism section storage chamber 40 in which the electric mechanism section 26 is arranged, and at the front of the ice tray storage chamber 39, a drawer port 41 for the ice tray 27 is formed.

  The ice tray 27 slides back and forth in the ice tray storage chamber 39 by a frame 42 (see FIG. 10) and a rail 38 provided on the ice making frame 29 side. When the ice tray 27 is stored in the ice tray storage chamber 39, the ice tray 27 is connected to the drive shaft 26a of the electric mechanism 26, and when the ice tray 27 is pulled out, the connection relationship with the drive shaft 26a is released.

  Further, the first cold air passage 33, the second cold air passage 34, and the third cold air passage 35 are provided between the upper wall 14 a and the ice making frame 29 when the ice making frame 29 is attached to the upper wall 14 a of the ice making chamber 14. Formed. The cold air blown out from the first cold air outlet 31 flows into the first cold air passage 33 and is stored in the ice tray by the wind direction plate 45 of the first cold air passage provided in the first cold air passage 33. It is led to the ice tray storage chamber opening 43 on the side wall 29c of the ice tray storage chamber 29c partitioning the chamber 39 and the first cold air passage 33 and blown to the ice tray 27.

  On the other hand, the cold air led from the second cold air outlet 32 to the second cold air passage 34 side flows by the airflow direction plate 44 of the second cold air passage and the third cold air passage 35 side. And flows into the ice tray storage chamber 39 and the ice detection lever storage chamber 36, respectively.

  Reference numeral 46 denotes an arcuate portion constituting a part of the ice making frame 29 (see FIG. 7). The arc-shaped portion 46 is formed on the ice tray 27 having two rows of ice making sections on the upper surface of the ice tray 27 of the ice tray storage chamber 39 and on the rotation start side of the ice tray 27, that is, along the drive shaft 26a. One row is provided in the upper longitudinal direction.

  The arc-shaped portion 46 allows the cold air entering the ice tray storage chamber 39 from the ice tray storage chamber opening 43 formed in the ice tray storage chamber side wall 29c to efficiently hit the surface (upper surface and side surfaces) of the ice tray 27. Lead to. That is, the arc-shaped portion 46 converts the cold air blown into the ice tray storage chamber 39 from the ice tray storage chamber opening 43 provided in the ice tray storage chamber side wall 29c forming the first cold air passage 33 with the arrow in FIG. As shown in FIG. 5, the water is guided along the ice tray 27 to quickly cool the water in the ice tray 27 to shorten the ice making time.

  The electric mechanism unit 26 incorporated in the ice making frame 29 is made to ice from the ice making plate 27 by twisting the ice making plate 27. At the time of deicing, for example, a torque of 1 to 4 N · m is required. In other words, the ice making frame 29 needs to be strong enough to withstand this torque. Therefore, the strength of the ice making frame 29 of the present embodiment is improved by the arc-shaped portion 46. Further, a first cold air passage 33 and a third cold air passage 35 having a U-shaped cross section when viewed from the front are formed on both sides of the ice tray storage chamber 39 to enhance rigidity (see FIG. 8). In addition, by providing the ice detecting lever storage chamber 36 on the side of the third cold air passage 35 having a smaller cross-sectional area than the first cold air passage 33, the rigidity is improved and the cold air distribution is balanced.

  47 is a temperature sensor. The temperature sensor 47 is a temperature detection means for detecting whether ice is formed in the ice tray 27, and is attached near a cold air intake 48 provided near the end of the arc-shaped portion 46.

  The arc-shaped portion 46 is curved so as to approach the ice tray 27 from the upper surface of the ice making frame 29, and the cold air intake 48 is provided near the end of the arc-shaped portion 46 at a position close to the ice tray 27. As a result, the temperature detected by the temperature sensor 47 is close to the water temperature in the ice tray 27, and the ice making control is more accurate.

  Further, the temperature sensor 47 may also serve as temperature detection means for controlling the temperature of the upper freezer compartment 7a and the lower freezer compartment 7 in the same temperature range. In this case, if the cold air entering the third cold air passage 35 can also be detected, it can be detected without the influence of the water temperature of the ice tray 27.

  The water in the ice tray 27 becomes ice when cooled for a predetermined time. The cold air temperature entering the temperature sensor 47 side from the cold air inlet 48 becomes lower as the water is cooled. Then, after this cold air temperature becomes, for example, −10 ° C. or less and a certain time has elapsed, it is judged by the control board that ice making is completed, and the ice tray 27 is rotated to perform the ice removing operation.

  Next, the temperature sensor 47 will be described. The temperature sensor 47 is stored in the temperature sensor storage unit 49. The temperature sensor housing 49 is adjacent to the tip of the third cold air passage 35, that is, in front of the third cold air passage 35 (see FIG. 5). Moreover, the temperature sensor storage part 49 is a space defined by the arc-shaped part 46 (see FIG. 7). The temperature sensor storage portion 49 communicates with the third cold air passage 35 and is configured such that a part of the cold air flowing through the third cold air passage 35 flows.

  The arc-shaped portion 46 has an arc shape that is slightly larger than the rotation trajectory in which the ice tray 27 rotates for deicing, improves the rigidity of the ice making frame 29, and cools air from the first cold air passage 33. Efficiently guide to ice tray 27.

  Further, the arc-shaped portion 46 is configured to be curved so that the ice making frame upper surface 29 a approaches the ice making tray 27. For this reason, cold air (mostly passing through the top surface of the ice tray 27 and heat-exchanged with water or ice in the ice tray 27) flows into the temperature sensor storage portion 49 formed in the arc-shaped portion 46 from the cold air intake port 48. ) Is close to the temperature of water or ice in the ice tray 27.

  Reference numeral 50 denotes an exhaust hole that guides the cold air introduced into the temperature sensor housing 49 to the outside of the temperature sensor housing 49. The cold air flowing out from the exhaust hole 50 flows toward the ice storage container 30 side.

  The amount of cold air flowing into the temperature sensor housing part 49 from the third cold air passage 35 is such an amount that it is possible to prevent the temperature from rising due to the outside air flowing into the temperature sensor housing part 49 when the ice making chamber door 10 is opened. is there. Accordingly, the temperature sensor storage unit 49 communicates with the tip of the third cold air passage 35 so that the remaining cold air that has blown most of the cold air into the ice detecting lever storage chamber 36 enters the temperature sensor storage unit 49. did. In other words, the temperature sensor storage portion 49 is provided near the ice making chamber door 10 and at a position away from the cooler chamber 16 and above the ice making tray 27. Thereby, the detection accuracy of the temperature sensor 47 can be improved.

  Water supply, ice making, and ice removal in an automatic ice maker are performed as follows. A certain amount of water in the water storage tank 24 is supplied to the ice tray 27 by a pump (not shown) or the like. The temperature of the supplied water in the ice tray 27 is the same as that in the refrigerator compartment 6 immediately after the water supply, but is cooled by the cold air blown through the first cold air passage 33 and the second cold air passage 34, It becomes ice after a predetermined time. In the meantime, the temperature sensor 47 detects the cold air temperature from the cold air inlet 48 and sends a signal to a control board (not shown).

  After a certain period of time has elapsed at the ice making temperature (temperature of change of state from water to ice), the control board operates the electric mechanism unit 26. When the electric mechanism unit 26 operates, the ice detecting lever 28 operates first to detect whether or not the ice storage container 30 is full of ice. When the ice storage container 30 is full of ice, the ice tray 27 waits without deicing, but when it is not full, the ice tray 27 is rotated from the ice-making position to the ice-breaking position to perform a twisting operation. Then, the ice in the ice tray 27 is dropped into the ice storage container 30.

  Thereafter, the ice tray 27 returns to the ice making position and receives ice from the water storage tank 24 to make ice again. By repeating this operation, ice is secured in the ice storage container 30.

  The frost that has grown on the ice detecting lever 28 when the ice making chamber door 10 is opened and closed is sublimated by the cold air blown into the ice detecting lever storage chamber 36 from the third cold air passage 35, and the ice detecting lever 28 has no frost. maintain.

  Since the present invention has the configuration described above, the following effects can be obtained. That is, in a refrigerator equipped with an automatic ice maker having an ice detecting lever for detecting an ice storage amount, and an electric mechanism portion for rotating and deicing an ice tray when the ice detection lever detects that the ice storage amount is insufficient. The automatic ice maker includes an ice making frame, and the ice making frame includes an ice making tray storage chamber for storing the ice tray, and an ice detection lever storage chamber that is partitioned from the ice tray storage chamber and stores the ice detection lever. Is formed, a first cold air passage for guiding cold air from the side of the ice tray storage chamber, a third cold air passage for guiding cold air to the ice detecting lever storage chamber, an upper portion of the ice tray storage chamber, and A second cold air passage for guiding cold air to the third cold air passage.

  As a result, the ice detection lever does not hinder the supply of cold air to the ice tray, so that the ice making capacity can be improved. Moreover, since low-humidity cold air can be easily introduced into the ice detection lever storage chamber, it is possible to suppress the cold air from staying in the ice detection lever storage chamber and avoid frost formation on the ice detection lever. Therefore, it can be suppressed that frost is formed on the ice detecting lever and accurate ice detection cannot be performed.

  Further, since the first cold air passage and the third cold air passage are formed across the ice tray storage chamber, the strength of the ice making frame itself can be improved.

  The second cold air passage is provided at an upper portion of the electric mechanism unit, and includes a wind direction plate that distributes the cold air to the ice tray storage chamber and the third cold air passage. This facilitates the introduction of cold air to the entire rectangular ice tray, and can suppress uneven cooling.

  In addition, an ice detection lever storage chamber opening is formed in a side wall of the ice detection lever storage chamber, and the cold air that has passed through the ice detection lever storage chamber opening from the third cold air passage is guided to the ice detection lever storage chamber. Thereby, it is possible to suppress the cold air staying in the entire ice detecting lever storage chamber and to avoid the frost on the ice detecting lever portion.
