The setting of the above mentioned requirements enables not only the prevention of useless ice making but also the prevention of the delay in the ice making as caused by blowing made when the temperature in the refrigerating chamber rises.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a refrigerator equipped with an automatic ice making device.

[0002]

In a conventional refrigerator equipped with an automatic ice making device, the ice making capacity of the automatic ice making device largely depends on the basic cooling performance of the refrigerator.
No special measures were taken to improve ice making capacity. For example, the means for adjusting the ice making capacity is only a quick freezing switch, a temperature adjustment dial, etc., which are common to other functions of the refrigerator, or only adjusting the operating efficiency of the compressor.

[0003] Since there is no special means for improving the ice making capacity, the conventional refrigerator equipped with an automatic ice making device has a problem that the ice making capacity is low. For example, one ice making took about 90 minutes at the shortest, and the amount of ice making per day was about 1.5 kg at the maximum. Due to the low ice-making capacity, ice is insufficient during a period of high demand for ice, such as in summer. Further, in the refrigerator equipped with the conventional automatic ice making device, there is no special means for adjusting the ice making ability as described above, and the ability to adjust the ice making ability is also poor.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a refrigerator equipped with an automatic ice making device in which the ice making capacity is greatly improved. An object of the present invention is to provide a refrigerator equipped with an ice making device.

[0005]

SUMMARY OF THE INVENTION The present invention aims to achieve the above object, and the invention according to claim 1 comprises an ice tray,
Temperature detecting means for detecting the temperature of the ice tray, water tank for supplying water to the ice tray, water tank detecting means for detecting the water tank or the presence or absence of the water, and the ice making in accordance with the temperature of the ice tray. Ice tray driving means for causing the tray to perform an ice releasing operation, an ice storage section for storing ice separated from the ice tray, an ice storage amount detecting means for detecting the amount of ice stored in the ice storage section, and blowing air to the ice tray. And a blower for circulating cool air which operates or stops according to the presence or absence of water or the amount of ice stored in the water supply tank.

When cold air is blown to the ice tray by the cool air circulation blower, the cooling of the ice tray is promoted, and ice is made quickly, thereby shortening the ice making time. However, if the water tank is detached, the water tank is empty, or the ice storage is full, it is meaningless to perform rapid ice making. The operation and stop of the cool air circulation blower are controlled according to the presence or absence of ice or the amount of ice storage.

According to a second aspect of the present invention, there is provided a refrigerator equipped with an automatic ice making device according to the first aspect of the present invention, wherein a door open / closed state detecting means for detecting an open / closed state of a door of a freezing room containing the automatic ice making device is provided. And a defrosting state detecting means for detecting whether or not there is an air conditioner, wherein the cool air circulation blower is operated or stopped according to the open / closed state or the defrosted state of the door of the freezing room.

If air is blown while the temperature in the freezing room is rising, the ice making is delayed rather than performed. The temperature in the freezer compartment rises during defrosting and when the door of the freezer compartment is opened for a long time. Therefore, in the refrigerator with the automatic ice making device according to the second aspect of the present invention, the operation and stop of the cool air circulation blower are controlled according to the open / closed state or the defrosted state of the freezer compartment door.

According to a third aspect of the present invention, in the refrigerator with the automatic ice making device according to the second aspect of the present invention, the blower for circulating cool air has a condition that an ice storage amount detected by the ice storage amount detecting means is not full, and All of the conditions that the water supply tank is mounted with water, the condition that the door of the freezing compartment is closed, and the condition that the defrosting state is not performed are satisfied. When, or when all these conditions are satisfied and the quick ice switch is operated to the fast ice mode side, the operation is performed.

[0010] By operating the blower for circulating cool air when the above four conditions are satisfied, rapid ice making can be surely performed. The quick ice switch allows the user to select quick ice making.

According to a fourth aspect of the present invention, in the refrigerator with the automatic ice making device according to the third aspect of the present invention, the blower for circulating cool air is configured such that when the ice storage amount detected by the ice storage amount detecting means becomes full, The operation is temporarily stopped when the water supply tank is removed or becomes empty, when the door of the freezer is opened, or when the defrosting state is reached.

Thus, it is possible to prevent useless operation of the cool air circulation blower, and to prevent delay in ice making due to blowing when the temperature in the freezing compartment is rising.

According to a fifth aspect of the present invention, in the refrigerator with the automatic ice making device according to the fourth aspect of the present invention, the cool air circulation blower stops when the quick ice switch is operated to the normal mode side.

That is, when the quick ice switch is operated to the normal mode, normal ice making is performed instead of quick ice making.

According to a sixth aspect of the present invention, in the refrigerator according to the fourth or fifth aspect of the present invention, the blower for circulating cool air is temporarily stopped during a deicing operation or a water supply operation.

As a result, unnecessary consumption of the cool air circulation blower is reduced, and the life thereof is extended. According to a seventh aspect of the present invention, in the refrigerator with the automatic ice making device according to any one of the fourth to sixth aspects, there is provided an ice release prohibition timer for prohibiting the ice release operation of the ice tray for a predetermined time. In the fast ice mode in which ice is driven, the time of the ice release prohibition timer is set to 20 to 50% of that in the normal mode in which ice is formed without operating the cool air circulation blower.

The reason why the time period of the ice release prohibition timer is shorter in the fast ice mode than in the normal mode is that ice is made more quickly in the fast ice mode, so that incomplete ice is formed. This is because the time during which the ice making operation of the ice tray should be prohibited in order to prevent the occurrence of ice is also shortened.

According to an eighth aspect of the present invention, there is provided the refrigerator with the automatic ice making device according to the fourth to seventh aspects of the present invention, further comprising an indicator which lights up in the fast ice mode to indicate the fast ice mode.

Thus, the user can externally recognize that the mode is the fast ice mode.

The room temperature sensor 2 serves as outside air temperature detecting means for detecting the room temperature outside the refrigerator. The freezer compartment door switch 3 serves as door open / closed state detecting means for detecting the open / closed state of the door 12 of the freezer in the refrigerator having the automatic ice making device 11 built therein. For example, it turns on when the door 12 is closed and turns off when it is open. The defrost sensor 4
Is a defrosting state detecting means for detecting whether or not the freezer is in a defrosting state. The water supply tank switch 5 serves as water supply tank detection means for detecting the presence or absence of a removable water supply tank 14 for supplying water to the ice tray 13 and for detecting the presence or absence of water in the water supply tank 14. For example, a water tank
14 is installed, and is turned on when there is water in the water tank 14, when the water tank 14 is detached, and
Even when the water supply tank 14 is mounted, it is turned off when the inside of the water supply tank 14 is empty (water supply standby state). The ice making sensor 6 serves as temperature detecting means for detecting the temperature of the ice making tray 13 to determine whether or not ice has been formed. The tray position detecting Hall IC 7 detects the position of the ice tray 13 that operates for ice removal. The ice detection hall IC8
Is an ice storage amount detecting means for detecting an ice storage amount in the ice storage unit 15 for storing ice automatically released from the ice tray 13. The quick-ice switch 9 is pressed by the user when he wants the ice in a hurry. In principle, when the switch is turned on, the fast-ice mode is set, and when the switch is turned off, the normal mode is set.

The microcomputer 1 comprises a room temperature sensor 2, a freezer compartment door switch 3, a defrost sensor 4, a water supply tank switch 5, an ice making sensor 6, a dish position detecting hall IC 7, an ice detecting hall IC 8, and a quick ice. LED drive circuit 2 that drives LED 21 based on input from switch 9
2, a fan drive circuit 24 for driving a cool air circulation fan 23, which is a cool air circulation blower dedicated to cooling the ice tray 13, a compressor drive circuit 26 for driving a compressor 25 of a refrigerator, and a motor 27 for ice tray drive means. It controls the motor drive circuit 28 and the water supply electromagnetic valve drive circuit 30 that drives the water supply electromagnetic valve 29.

The LED 21 serves as a display visible to the user, and includes an LED which is provided near the quick ice switch 9 and is turned on in the fast ice mode and turned off in the normal mode. The cool air circulation fan 23 blows cool air to the ice tray 13 to promote ice making. In addition,
The control will be described in detail later. The ice tray driving means will also be described later. The water supply solenoid valve 29 is provided with an ice tray from the water supply tank 14 to supply water to the ice tray 13 in a timely manner.
It opens and closes the waterway to 13.

The defrosting means that the compressor 25 is stopped and the freezing room is heated by a defrost heater provided in an evaporator (not shown).

Next, the mechanical structure of the automatic ice making device 11 will be described with reference to FIGS. The automatic ice making device 11 has a mechanism portion 42 serving as ice tray driving means incorporated in a case 41 at a rear portion. This mechanism section 42
Although not shown in detail, the ice tray 13 is rotated upside down and twisted by the motor 27 or the like and twisted to cause the ice tray 13 to perform an ice releasing operation. The ice removing operation is performed by the ice making sensor 6 provided below the ice making tray 13.
(Not shown in FIGS. 3 to 6) is performed when it is determined that ice is formed from the temperature of the ice tray 13 and other predetermined conditions are satisfied. The ice separated from the ice tray 13 falls into the ice storage unit 15 located below the ice tray 13. At the same time, an ice storage amount detection lever 43 having the ice detection hall IC 8 extends from the mechanism section 42. The ice storage amount detection lever 43 is located on one side of the ice tray 13.

The case 41 has a cover 44 for covering the ice tray 13 from above.
A cold air duct 45 having a cylindrical shape is provided on a side of the ice storage amount detection lever 43 opposite to the side of the ice storage amount detection lever 43. This cold air duct 45
The inside is a cold air passage 46 and has a blowout port 47 on the side surface on the ice tray 13 side. The cool air passage 46 has a length substantially equal to the longitudinal length of the opening 13a on the upper surface of the ice tray 13. Further, the outlet 47 is also provided with a cold air passage 46.
Of the ice tray 13 and substantially the entire length thereof. At the same time, the outlet 47 opens slightly downward toward the opening 13a of the ice tray 13. Further, the cold air duct 45
The cool air circulation fan 23, which is rotationally driven by a motor, is provided at the front end of the chiller, that is, at the end opposite to the mechanism 42 with respect to the ice tray 13. This cool air circulation fan
23 is in a position that does not completely interfere with the ice tray 13. Then, as indicated by an arrow A, the cool air in the freezer is forcibly convected by the cool air circulation fan 23. At that time, the cool air sucked into the cool air circulation fan 23 is supplied to the ice tray 13 from the outlet 47 through the cool air channel 46, and the ice tray 13 is cooled. Cold air is blown from obliquely over the ice tray 13 over substantially the entire length thereof, depending on the position and directionality of the outlet 47.

Next, the control of the operation and stop of the cooling air circulation fan 23 by the microcomputer 1 will be described in detail with reference to the flowchart of FIG. The cooling air circulation fan 23 includes a signal from the fast ice switch 9, the presence or absence of water in the water supply tank 14 detected by the water supply tank switch 5, the amount of ice stored in the ice storage unit 15 detected by the ice detection hall IC 8, and the freezing. The operation or stop is performed according to the open / closed state of the freezer compartment door 12 detected by the compartment door switch 3 or the defrosting state detected by the defrosting sensor 4. That is, when the quick ice switch 9 is turned on (step S1), the condition that the water supply tank 14 is mounted with water (step S2);
The condition that the ice storage amount of the ice storage unit 15 is not full (step S
3) and the condition that the freezer compartment door 12 is closed (step S4) and the condition that the freezer compartment is not in the defrosting state (step S5) are satisfied. The fan 23 operates (step S6). On the other hand, when the quick ice switch 9 is turned off (step S1), the cool air circulation fan 23 is completely stopped (step S7). Also,
When the water supply tank 14 is removed or becomes empty (step S2), when the amount of ice stored in the ice storage unit 15 becomes full (step S3), and when the door 12 of the freezing compartment is opened (step S3). S4) or when it is defrosted (Step S
In either case of 5), the cool air circulation fan 23 is temporarily stopped (step S7). That is, when the condition is satisfied again, the operation of the cool air circulation fan 23 is restarted.

At the same time, the cool air circulation fan 23 temporarily stops during the ice removing operation and the water supply operation even during the operation. The microcomputer 1 has a software function that includes an ice release prohibition timer 51 for prohibiting the ice release operation of the ice tray 13 for a predetermined time in order to prevent the ice release when the ice is not completely completed. However, in the fast ice mode in which ice is produced by operating the cool air circulation fan 23, the time during which the ice removal operation is prohibited by the ice removal prohibition timer 51 is performed without operating the cool air circulation fan 23. To 20% to 50% of the normal mode. This is because ice is made more quickly in the fast ice mode than in the normal mode, and the time during which the ice making operation of the ice tray 13 should be prohibited is also shortened. During the fast ice mode, the compressor 25 may be continuously operated unconditionally, or may be continuously operated when the outside air temperature detected by the room temperature sensor 2 is equal to or higher than a set value. Good. Further, in the fast ice mode, the LED 21 is lit to indicate that the mode is the fast ice mode.

Then, in the fast ice mode, the cool air is blown to the ice tray 13 by the cool air circulating fan 23, so that the cooling of the ice tray 13 is promoted, and ice is made quickly. As a result, the ice making time is reduced, and the ice making capacity is greatly improved. Therefore, even during a large demand for ice in summer or the like, ice can be supplied in a timely manner without running out of ice. At the same time, since forced convection of the cool air is performed, it is possible to prevent the smell of the food and the like in the refrigerator from being transferred, thereby preventing the ice from generating an odor.

When the water supply tank 14 is detached,
If the water tank 14 is installed but is empty,
Alternatively, when the ice storage section 15 is full, it is meaningless to operate the cool air circulation fan 23 to perform rapid ice making, but in such a case, as described above, the cool air circulation fan 23 Is stopped, useless ice making can be prevented, and useless power consumption can be suppressed.

It is wasteful to blow air when the temperature in the freezing room is higher than the freezing point, and it also delays the ice making. When the condition is obtained, the cool air circulation fan 23 is stopped, so that the delay of ice making can be prevented, and the cool air circulation fan 23 can be prevented from being wasted, and rapid ice making can be surely performed. The temperature inside the freezer compartment rises during defrosting and when the door 12 of the freezer compartment is opened for a long time.In these cases, the temperature of the freezer compartment rises because the cool air circulation fan 23 is stopped. It is possible to prevent the operation of the cooling air circulation fan 23 in a state where the cooling air circulation is being performed, and to always operate the cooling air circulation fan 23 at a certain temperature or lower.

Furthermore, the cool air circulation fan 23 is temporarily stopped during the ice-removal operation and the water supply operation even during operation, so that the motor of the cool air circulation fan 23 is further reduced in wasteful consumption. Can extend its lifespan.

Further, the time during which the ice removal operation is inhibited by the ice removal inhibition timer 51 is shorter in the fast ice mode than in the normal mode, so that the reduction of the ice making time in the fast ice mode can be reliably utilized. it can.

By turning on and off the fast ice switch 9, the user can set or cancel the fast ice mode, and adjust the ice making capacity.

Further, since the LED 21 is turned on in the fast ice mode, the user can easily and reliably recognize from the outside whether or not the fast ice mode is set.

The cold air is supplied to the opening 13 on the upper surface of the ice tray 13.
a is blown obliquely from above, so that the bounce of the wind is reduced as compared with the case of blowing vertically from above, and the escape (loss) of the wind is reduced as compared with the case of blowing from the side. The cold air can be blown most efficiently.

Further, the ice storage amount detecting lever for the ice tray 13
Since the cool air is supplied from the side opposite to 43, the cool air can be supplied closest to the ice tray 13 without being interfered by the ice storage amount detection lever 43. Therefore, the ice tray 13 can be efficiently cooled.

Further, since the length in the longitudinal direction of the opening 13a of the ice tray 13 and the length of the cold air flow passage 46 and the outlet 47 are substantially the same, it is possible to uniformly apply the cold air to the ice tray 13. This can reduce variations in ice making speed,
Ice can be made uniformly over the entire ice tray 13. And, by being able to reduce the variation of the ice making speed in each part of the ice tray 13,
The ice making time itself can be shortened.

FIG. 7 shows a second embodiment of the present invention. In the automatic ice making apparatus of the second embodiment, a long-length cross flow fan is provided at a portion corresponding to the cool air duct 45 of the first embodiment. Is arranged as a fan for cooling air circulation (blower for cooling air circulation) 56, and blows the ice tray 13 by forcibly convection the cool air directly without disposing a cool air duct. At this time, if the shaft case supporting the cool air circulation fan 56 can also be used as the cool air duct, the cost can be reduced. Note that the cool air circulation fan 56 needs to be at a position that does not interfere with the rotation trajectory of the ice tray 13 indicated by a chain line a.

It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made. For example,
When the water supply tank 14 is removed or becomes empty, to prevent useless ice making and operation of the cool air circulation fan 23,
Alternatively, when the amount of ice stored in the ice storage unit 15 becomes full, even if the cool air circulation fan 23 is automatically stopped once as in the above-described embodiment, a quick ice switch is required to return to the fast ice mode again. 9 may be required.

In order to prevent the formation of incomplete ice, in the fast ice mode, the set temperature which is compared with the temperature detected by the ice making sensor 6 and which is the condition for the ice making tray 13 to perform the ice releasing operation is set to the normal mode. May be set lower than that for.

Also, in consideration of the demand for ice in summer or the like, when the outside air temperature detected by the room temperature sensor 2 becomes equal to or higher than a set value, the apparatus may automatically enter the fast ice mode.

The condition that the water supply tank 14 is installed with water therein, the condition that the ice storage amount of the ice storage unit 15 is not full, the condition that the freezer compartment door 12 is closed, and the following conditions: When the quick ice switch 9 is turned on in a state in which any of the conditions that the ice is not in the frost state is not satisfied, the fact that the quick ice switch 9 is turned on is stored by the storage means such as the microcomputer 1. Aside
When all of the above conditions are satisfied, a configuration may be adopted in which the fast ice mode is automatically entered. For example, if the quick ice switch 9 is turned on while the freezer door 12 is open, the fast ice mode is entered after the door 12 is closed.

Further, while it is detected that the ice storage amount of the ice storage unit 15 is not full, it is detected that the water is drained, that is, the water supply tank 14 is removed or the water is empty, and the outside air temperature is equal to or higher than the set value. In the case of, despite the demand for ice,
Since it is anticipated that there is no ice due to the draining state, it is also possible to automatically enter the fast ice mode after the detection of the draining state is canceled after refilling the water.

Further, the quick ice switch for enabling the user to select between the fast ice mode and the normal mode is not essential, and the ice making is always performed in the fast ice mode if a predetermined condition is satisfied. It may be.
