Further, the revolving door 10 forming the refrigerating chamber 5 is provided with a plurality of pockets 5b projecting inside the refrigerating chamber 5 in the closed state.
[0023]
The vegetable compartment 6 and the switching compartment 7, the ice making compartment 8, and the freezing compartment 9 are partitioned by a heat insulating partition wall 15 having a heat insulating material in order to reduce heat transfer between the two compartments. A cooler chamber 18 in which a cooler 16 and a cooler fan 17 are arranged is formed behind the vegetable chamber 6, the switching chamber 7, the ice making chamber 8 and the freezer chamber 9. The heat insulating partition wall 15 extends in the vertical direction behind the vegetable chamber 6 so that the heat insulating partition wall 15 is interposed between the cooler chamber 18 and the vegetable chamber 6.
[0024]
In the cooler chamber 18, a cooler fan 17 is disposed above the cooler 16. Above the cooler chamber 18, there is formed a cool air passage 19 that connects the refrigerating chamber 6 and the cooler chamber 18 and through which the cool air cooled by the cooler 16 flows. Cooling air is supplied to the refrigerating room 5 through the cool air passage 19 by the fan 17 that is rotated by driving the fan motor 20 provided in the refrigerator. The cold air passage 19 is provided with a damper flap 21 for adjusting the amount of cold air supplied to the refrigerator compartment 5 in order to adjust the temperature of the refrigerator compartment 5 to an appropriate range.
[0025]
Further, the cold air cooled by the cooler 16 flows out forward from the fan 16 and is disposed between the cooler chamber 18 and the vegetable chamber 6 or the switching chamber 7, the ice making chamber 8 and the freezer chamber 9. The cool air passage 22 is lowered and flows into the switching chamber 7, the ice making chamber 8 and the freezing chamber 9, and the switching chamber 7, the ice making chamber 8 and the freezing chamber 9 are cooled.
[0026]
The cold air passing through the cool air passage 19 from the cooler chamber 18 through the damper flap 21 forms the cold air passage 19 so as to rise along the wall surface of the inner box 3 after passing through the damper flap 21. Has been. Further, the cold air passage 19 is branched into a plurality of passages behind the refrigerator compartment 5. This branched cold air passage extends vertically on both sides of the back surface of the refrigerator compartment 5. A plurality of shelves 23 are arranged in the refrigerator compartment 5 at intervals in the vertical direction, and the interior of the refrigerator compartment 5 forms a vertically partitioned space. This partitioned space communicates vertically with a gap between the door pocket 5 b and the shelf 23. A plurality of cold air outlets are formed in the upper and lower sides, each communicating with the space formed by the shelf 23 and the branched cold air passage, through which the cold air flows out toward the refrigerating chamber 23.
[0027]
A ventilating duct 25 having a substantially cylindrical shape is provided at the center of the back surface of the refrigerator compartment 5 positioned between the plurality of cold air passages, and a fan for the refrigerator compartment for supplying cold air from the refrigerator compartment 5 to the ventilation duct 25. 26 are arranged. The ventilation duct 25 is vertically long, and the refrigerator compartment fan 26 is disposed below the ventilation duct 25, and these fans are provided extending vertically in the center of the back surface of the refrigerator compartment 5.
[0028]
The refrigerating room fan 26 sucks the cold air in the refrigerating room 5 from the refrigerating room cold air suction ports provided on the left and right sides thereof, and supplies the blown out cold air to the air duct 25. The ventilation duct 25 is hollow so that the cold air flows inside, and a plurality of duct discharge ports are formed at positions corresponding to the spaces defined by the shelves 23 of the refrigerator compartment 5 so that the fan for the refrigerator compartment is provided. The cold air supplied by 26 is discharged from the duct discharge port into the refrigerator compartment 5 as shown by the arrow in FIG. The ventilation duct 25, the refrigerator compartment fan 26, and other configurations are set so that the discharge speed of the cold air from the duct discharge port is larger than the discharge speed of the cold air from the cold air discharge port. The cold air sent to the space partitioned by the shelves 23 in the refrigerator compartment 5 flows forward of the refrigerator compartment 5 and, after passing through the front end of each shelf 23, the shelf 23 and the pocket 5b It descends from the gap. As shown by the arrow, the descending cold air flows above the shelf surface on the upper surface side of the ice greenhouse 5a to the rear of the refrigerating room 5 and is sucked into the refrigerating room fan 26 from the suction port. Thus, the refrigerator compartment fan 26 and the ventilation duct 25 are means for circulating cold air in the refrigerator compartment 5. The ventilation path of the cool air in the refrigerator compartment 5 by the refrigerator compartment fan 26 and the ventilation duct 25 is independent of the cooler 16 without passing through the cooler 16. The refrigerating room fan 26 is a centrifugal fan that draws in the cold air in the refrigerating room that has flowed in from the suction ports at the lower portions on both sides of the back side of the refrigerating room 5 and blows it out toward the upper ventilation duct 25.
[0029]
The motor 29 that drives the ventilation duct 25 is disposed above the ventilation duct 25 and rotates the cylindrical ventilation duct 25 that extends vertically along the vertical axis. The direction of the duct discharge port is changed by the rotation of the ventilation duct 25, and the direction of the cold air discharged from the duct discharge port to the refrigerator compartment 5 is adjusted.
[0030]
The wind direction plate 30 provided in the ventilation duct 25 is formed so as to cross the passage in the ventilation duct 25 at a position corresponding to each duct discharge port, for example, immediately above the duct discharge port. A part of the cold air in the refrigerating chamber flowing from the lower side to the upper side is changed in the direction of the refrigerating chamber 5 so as to easily flow out from the duct outlet at a high speed.
[0031]
A part of the cold air discharged into the refrigerator compartment 5 from the discharge outlet for blowing out the cold air supplied from the cooler chamber 18 and the duct outlet for blowing out the cold air sucked from the refrigerator compartment 5 and the fan 26 for the refrigerator compartment. Although circulating in the refrigerator compartment 5 through the ventilation duct 25, a part of the remaining cold air flows into the vegetable compartment 6 through an opening 31 formed below the refrigerator compartment 5 and communicating with the vegetable compartment 6. The cold air that has flowed into the vegetable compartment 6 flows upward in the vegetable compartment 6 toward the front of the refrigerator, descends the front of the container, and then flows backward in the lower portion of the container. It returns to the cooler chamber 18 through the return opening and the cool air return passage formed therein.
[0032]
Thus, the cold air in the refrigerator is a circulation path in which the cold air cooled by the cooler 16 returns from the cooler chamber 18 to the cooler chamber 18 via the refrigerator compartment 5 or the vegetable compartment 6 by the rotation of the cooler fan 17. And a circulation path in which cold air in the refrigerating chamber is sucked by the refrigerating chamber fan 26, flows out from the cold air discharge port to the refrigerating chamber 5 through the ventilation duct 25, and flows into the refrigerating chamber fan 26 again. It is.
[0033]
The centrifugal fan 26 is disposed below the ventilation duct 25, and cold air suction ports are formed on both the left and right sides of the refrigerator compartment fan 26. An inflow passage 35 is formed between the suction port and the refrigerator compartment fan 26. The inflow passage 35 is provided with a refrigerator temperature sensor which is a temperature detecting means for detecting the temperature of the cold air flowing through the passage. Based on the temperature detected by the refrigerating room temperature sensor, the temperature in the refrigerating room 5 is determined, and the flow of the cold air is adjusted by the damper flap 21. For example, when the determined temperature is higher than a predetermined temperature and it is determined that the refrigerator compartment 5 needs to be cooled, the damper flap 21 is opened. If it is determined that the determined temperature is lower than a predetermined temperature and cooling is not required, the damper flap 21 is closed.
[0034]
In addition, in order to detect the temperature of the storage space partitioned by each shelf 23 in the refrigerator compartment 5, at each height position corresponding to the storage space of each shelf 23 and between the shelf 23 and the pocket 5b. Direction determination sensors 37 as temperature detecting means are arranged on the left and right side wall surfaces. The direction determination sensor 37 detects the temperature of the cold air that has flowed forward through the storage space partitioned by the shelf 23. When this cold air reaches the front end of the shelf 23, it cools the pocket 5b and descends the space between the pocket 5b toward the lower part of the refrigerator, and the cold airflow to the refrigerator fan 26 disposed below. It heads for the opening 31 formed under the entrance 27 and the ice greenhouse 5a.
[0035]
The direction determination sensor 37 detects the temperature of the cold air that has flowed through the storage space partitioned by the shelf 23. When a stored item is placed on the upper surface of the shelf 23, the flowing cold air exchanges heat with the stored item, and the temperature changes. Since a plurality of direction determination sensors 37 are arranged on both the left and right wall surfaces forming the refrigerator compartment 5, the temperature of the cold air flowing on both the left and right sides above each shelf 23 is detected, and the temperatures on both sides are compared with each other. Which side of the cold air temperature is higher is detected. And when the detected temperature of the higher side is higher than the set temperature of the refrigerator compartment 5, a predetermined direction on the higher temperature side where the direction of the cold air outlet of the ventilation duct 25 is detected is detected. The ventilation duct 25 is rotated so as to be directed to stop. Then, the cold air supplied to the ventilation duct 25 by the rotation of the refrigerator fan 26 is blown out from the discharge port toward the detected temperature side of the refrigerator compartment 5.

While cleaning the ice maker, the cleansing indicator 78c is lit.
[0071]
The operation switches 61 to 68 are provided with three types of push buttons 61b to 68b in a combination of shape and size. Thereby, the types of the operation switches 61 to 68 can be easily recognized by the push buttons 61b to 68b, and the operation can be performed reliably. In particular, the three types of push buttons 61b to 67b of the operation switches 61 to 67 are different from the push buttons 61b to 63b for setting the rapid cooling operation and the push buttons 66b and 67b for setting the temperature of the storage room. The push button 64b for setting different operation functions of the switching chamber 7 is made smaller than the other push buttons 61b to 63b, 66b, 67b. This makes it possible to easily operate the push buttons 61b to 63b, 66b, and 67 that are generally used frequently, and to erroneously operate the push button 64b that has a particularly low influence on the food to be cooled. Can be reduced. Specifically, the push buttons 61b to 63b are substantially elliptical and large, the push buttons 66b and 67b are substantially rectangular and large, and the push buttons 64b and 68b are substantially rectangular and small.
[0072]
Here, audio output by the audio device 80 will be described. When the speed cooling switch 61 is pressed, the speed cooling decompression display 71a of the display unit 70 is turned on, and a buzzer sound is output from the buzzer 54, and then, for example, “starts speed cooling” is output from the speaker 83. . When the setting of the speed cooling operation is completed after a predetermined time, for example, a sound is output from the speaker 83 that “speed cooling is finished”.
[0073]
Similarly, when the speed refrigeration switch 63 is pressed, the speed refrigeration display unit 73a of the display unit 70 is turned on, and after a buzzer sound is output from the buzzer 54, for example, a voice is output saying "Start speed refrigeration". . When the setting of the speed freezing operation ends after a predetermined time, for example, a sound is output from the speaker 83 that “speed freezing is finished”.
[0074]
In addition, the switching room setting switch 64 can switch between seven temperature zones of freezing, soft freezing, partial, ice temperature, chilled, refrigerated, and wine, but when set to partial, the buzzer 54 outputs a buzzer sound. For example, “I set it to partial. It is suitable for processing meat and fish, and its processing. Because it is frozen and stored a little, it is suitable for something that is boiled or baked”. And the specific contents thereof can be notified. Thus, in this Embodiment, it is the function which notifies the driving | operation function and the specific content of the switching room 7 which were set with the audio | voice.
[0075]
It should be noted that when a setting is made by an operation switch, a sound corresponding to each set function is output after a buzzer sound is output.
[0076]
Next, the demo function will be described. As described above, the demo function is intended to enhance the demonstration effect during the exhibition at the store. That is, when purchasing a refrigerator, customers often check the specifications and design of the refrigerator with the actual product and catalog at a store or the like, and select a refrigerator to purchase. Therefore, a demo function is provided so that customers can easily understand the functions and features of the refrigerator. In this demonstration function, for example, by pressing the ice making switch 68 and the freezer compartment temperature setting switch 67 at the same time for several seconds (for example, 5 seconds) while the refrigerator compartment door 10 is opened, the demonstration mode is decided, and the demonstration of the display unit 70 is performed. An intermediate display 79 is performed.
[0077]
The demo function includes, for example, the fan 26 and the cylindrical ventilation duct 25 at the time of the speed cooling operation for cooling the food in the refrigerator compartment 5 described above or at the time of the speed decompression operation for putting the frozen food in the refrigerator compartment 5 for thawing. Is operated with the refrigerator door closed, but this does not allow the customer to know how they are moving. For this reason, when the demonstration function is set, the refrigerator compartment fan 26 and the cylindrical ventilation duct 25 are operated even when the door of the refrigerator compartment 10 is open.
[0078]
Also, when the demo function is activated, for example, when the refrigerator temperature setting switch 66 is pressed, “The refrigerator is speed. If it is beer, it is 30 minutes like a freezer by the time of drinking. Speed thawing is only 15 minutes until it is cut. PAM delivers amazing energy savings. The world's first twin PAM refrigerator, a commercial feature or feature of a refrigerator.
[0079]
In consideration of the fact that this demo function is often used in a place with a large noise of about 80 dB, the demo function state is confirmed by the operation unit microcomputer 52 of the operation board 55, and an audio signal is transmitted by the amplifier 82 from the normal use. The volume is increased by amplification. In consideration of the fact that it can be used even in a place with relatively low noise, the volume during the demo function is set to the normal volume by, for example, pressing and holding the speed refrigeration switch 63 for a set time (for example, 3 seconds). It can be set to a higher level by long pressing again.
[0080]
Further, at the time of the demonstration function, the switching room display unit 74 of the display unit 70 blinks frozen, soft frozen, partial, ice temperature, chilled, refrigerated, wine display periodically, for example, in a 1 second cycle so that the customer pays attention. To. At this time, when the switching room is set to the switching room setting switch 64, the set switching room display is lit for a predetermined time, and the function of the set switching room is output from the speaker 83 by voice. Causes the display to blink periodically again after a predetermined time has elapsed. As a result, the demonstration effect can be significantly improved.
[0081]
If the speed refrigeration switch 63 is pressed long, the sound volume can be varied as described above during the demonstration function, but the sound output can be turned on and off during normal use. However, since the demo function is for explaining the product to the customer, the audio output is set not to be turned off even if the above operation is performed during the demo function. As a result, it is possible to prevent the voice output from being turned off by mistake during the demonstration function.
[0082]
Similarly, when the speed cooling switch 61 is pressed and held for a long time, a button lock function is set to lock the button so that even if the child tampers with the switch, the internal state does not change. It is set not to lock the button. This prevents accidental button locking during the demo function.
[0083]
Conventionally, the demo function has been switched by short-circuiting a set pin of a control board installed on the back of the refrigerator. In order to short-circuit this pin, it is necessary to prepare a dedicated connector, and when selling what was exhibited at the store, forgetting to remove this dedicated connector does not work properly at the customer's home Sometimes. Therefore, the conventional dedicated connector can be made unnecessary by setting the demo function using the switch on the operation board 55 in the operation panel 56 as described above.
[0084]
On the other hand, in a store or the like, the refrigerator is often turned off after closing with the demo function set. In this case, the demo function must be set again the next day. Therefore, once the demo function is set, the demo function state is stored in the storage unit 53 of the nonvolatile memory even when the refrigerator is turned off, and the demo function is operated even when the power is turned on again. The state of the refrigerator can be stored in the substrate 55.
[0085]
However, if the product is sold with the demo function set, it will not operate normally even if the customer turns on the refrigerator for normal operation, so the refrigerator is turned on with the demo function set. Then, after a buzzer sound is output by the buzzer 54 for a predetermined time (for example, 10 seconds), a voice output is made, for example, “Demo function set”. Further, a display during demonstration 79 is displayed on the display unit 70. As a result, even if the product is sold with the demo function set, it can be informed that the demo function is set when the customer turns on the refrigerator. The demo function can be canceled by performing the same operation as the setting again.
[0086]
Next, the alarm function will be described. As described above, the alarm function alerts the user based on the detection results of various sensors. For example, when the user forgets to close the door or when a failure occurs, the alarm function is activated with a buzzer and voice. Yes.
[0087]
In addition, when compressor noise of a refrigerator is generated, conventionally, it has not been easily known at which compressor rotation speed the noise is generated. Therefore, in the present embodiment, by using the seven segments of the refrigerator compartment temperature display unit 76b and the freezer compartment temperature display unit 77b, it is possible to display the number of rotations or the number of characters matching the number of rotations of the currently operating compressor. It is like that. As a display method, it is possible to display by using the switch on the operation board 55, for example, by simultaneously pressing the refrigerator compartment setting switch 86 and the freezer compartment setting switch 87 for several seconds. Since this operation is performed by a service person at the time of failure, for example, the switch operation described above is performed with the refrigerator compartment door 10 opened so that the compressor speed is not displayed even if the customer performs this operation by mistake. When the operation is performed, the compressor speed is displayed.
[0088]

Furthermore, the display unit 70 is disposed on the front surface of the refrigerator door 10 and displays the demo function, and the display control unit controls the display content related to the set demo function to be displayed on the display unit 70. Since the voice control means for controlling the voice content related to the set demo function to be notified by the speaker 83, the display content related to the demo function and the voice content can be used together for demonstration. The effect can be further improved.
[0116]
Moreover, since the audio content is related to the demonstration function including the content of the refrigerator's operation function and the content of the refrigerator's features, it is effective for selecting the target model to purchase by informing the customer of the operation function of the refrigerator. In addition to being able to demonstrate it, it is possible to commercialize the product quality of the refrigerator, thereby further improving the demonstration effect in stores and the like.
[0117]
In addition, the voice device 80 includes a voice IC that shares both the voice notification of the driving function and the voice notification of the demonstration function, and the content related to each set driving function and the demonstration function is voiced by the common voice IC and the speaker 83. Since the voice control means is used, it is possible to improve the demonstration effect at a storefront or the like with an inexpensive configuration.
[0118]
Furthermore, since it is a demo setting control means for controlling to set the demo function when a plurality of adjacent push buttons having different shapes and sizes of the operation switch 60 are simultaneously pressed in the opened state of the refrigerator door 10, It is easy to operate and the setting of the demo function due to incorrect operation can be reduced.
[0119]
Further, the contents relating to the set demo function are stored in the storage part of the nonvolatile memory, and the display part 70 is displayed based on the contents relating to the stored demo function when the commercial power supply of the refrigerator is turned on next time. When using a demonstration function by exhibiting a refrigerator at a storefront, etc., it is not necessary to set the demonstration function every time the commercial power is turned on and off, and the usability is greatly improved.
