Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a cooling storage for detecting a temperature inside a refrigerator and controlling a cooling device.

[0002]

2. Description of the Related Art In a refrigerator, for example, a temperature sensor detects a temperature in a refrigerating chamber, and the detected temperature is compared with a set temperature set by a user, and a cooling device is operated when the temperature is higher than the set temperature. When cooled to below the temperature, the operation of the cooling device is stopped so that the refrigerating chamber can be maintained at a predetermined set temperature.

[0003]

Considering that the stored items are stored from the center of the refrigerating chamber, it is most desirable to control the operation of the cooling device based on the temperature of the center of the storing chamber. . However, in order to measure the central temperature in the storage room, it is necessary to place a temperature sensor in the center of the refrigerating room, which impedes the accommodation of stored materials, which is impossible in reality. A temperature sensor is placed in one corner so that it does not interfere with storage.

Therefore, in the above conventional structure, there is a gap between the internal temperature detected by the temperature sensor and the actual central temperature in the internal storage. Therefore, in order to maintain the center of the refrigerator at exactly 5 ° C, for example, the user places a thermometer in the center of the refrigerator compartment and
It is very troublesome because it is necessary to experimentally find a set temperature to be maintained at ℃. Moreover, if it is 3
It is irrational to find out that the temperature is 3 ° C even if the center temperature is kept at 5 ° C by setting the set temperature to 3 ° C by finding out that the temperature is 3 ° C. Not only that, but there is also the risk of inadvertent operation mistakes being triggered.

The present invention has been completed based on the above circumstances, and an object thereof is to maintain the same temperature as the set temperature in the storage chamber and to display it as the temperature in the storage chamber. The purpose is to provide a cold store that allows the temperature to reach the actual temperature of the store.

[0006]

[Means for Solving the Problems] As a means for achieving the above-mentioned object, the invention of claim 1 is a storage chamber for accommodating stored items, a cooling device for cooling the storage chamber, and A temperature sensor for detecting the temperature in the storage chamber, operation control means for controlling the operation of the cooling device according to the temperature inside the refrigerator detected by the temperature sensor, and according to the temperature inside the refrigerator detected by the temperature sensor. In the one provided with a temperature inside display for displaying the temperature, a predetermined value corresponding to the temperature difference between the installation location of the temperature sensor and the storage location of the stored object is added to or subtracted from the internal temperature detected by the temperature sensor. A detection temperature correction means for correcting the temperature of the inside of the refrigerator, and an operation temperature of the cooling device is displayed based on the temperature corrected by the detection temperature correction means. The stage has a feature in that after installation in order to use the cooling storages user modifiable means the temperature value for correction are provided.

According to a second aspect of the present invention, a storage chamber for accommodating a stored item, a cooling device for cooling the storage chamber, a temperature sensor for detecting a temperature in the storage chamber, and a temperature sensor for detecting the temperature. In the one provided with operation control means for controlling the operation of the cooling device according to the inside temperature and the inside temperature display means for displaying the temperature according to the inside temperature detected by the temperature sensor, The storage temperature is provided with detection temperature correction means for correcting the internal temperature detected by the temperature sensor by adjusting a predetermined value corresponding to the temperature difference between the installation location of the temperature sensor and the storage location of the stored object. A ventilation path for cold air generated by a cooling device is formed outside the inner box that constitutes the cold air damper, and a cold air damper controlled by a cold air damper driving device is provided outside the ventilation path. Damper as the detection temperature correction means controlled to open and close based on the corrected temperature by displaying the temperature of the in-compartment temperature display unit is corrected,
In addition, the detected temperature correction means is characterized in that it is provided with means for allowing the user to change the temperature value for correction after the installation to use the cooling storage.

[0008]

In the invention of claim 1, the temperature inside the storage chamber is detected by the temperature sensor, and the temperature corresponding to the temperature difference between the location where the temperature sensor is installed by the detected temperature correcting means and the storage location of the stored object. It is corrected by adjusting the value to the measured temperature. Then, the operation of the cooling device is controlled based on the corrected temperature, and the location where the temperature sensor is installed is maintained at the corrected temperature. This means that the location of the storage is maintained at the set temperature. Further, since the corrected temperature is displayed on the in-compartment temperature display means, the actual temperature of the storage location of the stored goods is displayed.

According to the second aspect of the present invention, the cool air flows through the ventilation passage formed outside the inner box forming the storage chamber to indirectly cool the storage chamber inside the inner box. Therefore, excessive drying of the storage chamber is prevented. Further, a cool air damper is provided in the air passage through which cool air flows, and the opening and closing of the cool air damper is controlled based on the temperature corrected by the detected temperature correction means, so that the location where the temperature sensor is installed is maintained at the corrected temperature. Here, the temperature in the storage chamber is detected by the temperature sensor, but a predetermined value corresponding to the temperature difference between the location where the temperature sensor is installed by the detection temperature correction means and the storage location of the stored object should be adjusted to the measured temperature. Since it is corrected by the above, maintaining the location where the temperature sensor is installed at the corrected temperature means that the storage place of the collection is maintained at the set temperature set by the user.

The cooling device 2 including the cooler 10 and the like is housed so as to be freely drawn out, and the whole is opened and closed by the door 15.

The cooling device 2 is divided into a portion to be accommodated in the storage space 7 and a portion to be accommodated in the cooler chamber 5, and these are arranged vertically on the substrate 11. As a portion to be stored in the storage space 7, a compressor 8 is arranged on the back side, a condenser fan 12 driven by a motor is arranged on the front side, and a condenser 9 is arranged on the front side. Further, a cooler lid 13 for closing the inlet / outlet of the cooler chamber 5 is fixed to the upper surface of the condenser 9 via an L-shaped bracket 14.

On the other hand, in the main body, an inner box 2 constituting a storage chamber
0 is placed. The inner box 20 is made of stainless steel having thermal conductivity, and as shown in FIG.
1 and the like are arranged so as to leave a gap between them and the inner surface of the heat insulating material 6, and a cold air ventilation path 22 surrounding the inner box 20 is formed outside the inner box 20. The bottom of the inner box 20 is shown in FIG.
As shown in, the front slopes downward, and the ceiling surface slopes rearward. Further, reference numeral 23 shown in the figure is a shelf support column for attaching a shelf board (not shown), and 24 shown in FIG. 5 is an inner frame against which the door 3 is applied.

A temperature sensor 30 is attached to the upper part of the left inner wall of the inner box 20 in the storage chamber.
As shown in FIGS. 6 and 7, the temperature sensor 30 is mounted via a sensor mounting bracket 32 fixed to the inner box 20 by screws 31, and a sensor mounting piece portion 33 of the bracket 32 is shown in FIG. By being bent in the direction away from the wall surface of the inner box 20, the inner box 20 is held in a state of being separated from the inner surface of the inner box 20 and not being affected by thermal influence from the inner box 20 as much as possible. It should be noted that the sensor mounting bracket 32 is located above the mounting piece 33 and has an eaves 34
Is provided so that dew condensation water or the like that drops from above does not adhere to the temperature sensor 30. A sensor cover 35 is attached to the inner box 20 so as to cover the temperature sensor 30. The sensor cover 35 has mounting legs 36 at both ends fixed to the inner box 20 with screws 37. Therefore, as shown in FIG. 6, the sensor mounting bracket 32 and the temperature sensor 30 are laterally covered and opened vertically. Then, the air surrounds the temperature sensor 30 and is allowed to freely flow.

The electrical construction related to the main part of the present invention is as shown in FIG. In the figure, the control circuit 40
Although not shown in the figure, it includes a CPU and an A / D conversion circuit, receives signals from the temperature setting switch 41, the set value raising switch 42, the set value lowering switch 43, and the temperature sensor 30, and as described later, the compressor 8 and the digital signal. The display 44 is controlled. The temperature setting switch 41, the set value raising switch 42, the set value lowering switch 43, and the digital display 44 are provided in the operation box 16 on the front surface of the cooling device 2 together with the power switch 17, and the respective switches 41 to 43.
The user can freely operate the power switch 17 together with the power switch 17. The control circuit 40 functions as operation control means for controlling the operation of the cooling device 2 in accordance with the internal temperature detected by the temperature sensor 30, as will be apparent from the description of the operation described later, and also has a digital display. Together with the container 44, it also functions as an in-compartment temperature display unit that displays the temperature in accordance with the in-compartment temperature detected by the temperature sensor 30, and a location where the temperature sensor 30 is installed at the in-compartment temperature detected by the temperature sensor 30. It also functions as a detection temperature correction means for correcting by correcting a predetermined value (1.5 ° C. in standard, which will be clarified by the explanation of the operation later) corresponding to the temperature difference with the storage location of the stored matter. It has become.

This embodiment has the above-mentioned structure,
Next, the operation will be described. First, the user of this refrigerator can freely set the target temperature to be maintained in the storage (hereinafter referred to as "target temperature"). To set the target temperature, the temperature displayed on the digital display 44 is set to a desired value by the set value increasing switch 42 and the set value decreasing switch 43 provided on the operation panel, and then the temperature setting switch 41 is set. Turn on. This allows
The setting operation of the target temperature in the refrigerator is completed.

When the cooling device 2 is operated, the cool air generated in the cooler chamber 5 circulates through the cool air ventilation passage 22 formed on the outer side of the inner box 20 to circulate in the inner box 20. Indirectly cool the (storage room). As described above, since the inner box 20 is cooled from the outside, a decrease in humidity in the storage chamber is prevented, but the temperature distribution in the storage chamber becomes lower at the portion close to the inner wall surface, and the central portion where the stored items are stored. The part tends to have a slightly higher temperature than the inner wall surface. In the present embodiment, since the temperature sensor 30 is attached near the inner wall surface of the inner box 20 so as not to interfere with the putting in and out of the stored items, the inside temperature detected by the temperature sensor 30 is the inside temperature of the storage chamber. The temperature is higher than in the central part.
However, when the temperature sensor 30 detects the temperature inside the refrigerator, the temperature is converted into a digital value in the control circuit 40, and a value corresponding to 1.5 ° C. is added to the digital value. The temperature difference added by this correction is experimentally determined for each model as a temperature difference between the inner wall surface of the inner box 20 in which the temperature sensor 30 is installed and the central portion where the stored items are stored. It is preset at the time of factory shipment. Then, the CPU of the control circuit 40 uses the temperature sensor 30.
A process of comparing a temperature obtained by adding a correction value to the inside temperature detected by (hereinafter referred to as “corrected inside temperature”) with a set target temperature is performed. When the corrected internal temperature exceeds the target temperature, the compressor 8 is operated and cold air is generated in the cooler 10. When the corrected internal temperature is cooled below the target temperature, the operation of the compressor 8 is stopped. Be stopped. As a result, for example, when the target temperature set by the user is 5 ° C., the internal temperature of the refrigerator detected by the temperature sensor 30 is 3.5.
When the temperature exceeds 0 ° C (the temperature of the central portion is 5 ° C), the operation of the compressor 8 is started, and when the temperature detected by the temperature sensor 30 is lower than 3.5 ° C, the operation of the compressor 8 is stopped. As a result, the temperature of the installation part of the temperature sensor 30 is maintained at 3.5 ° C. Further, such a corrected internal temperature is displayed on the digital display 44 of the operation box 16. That is, when the internal temperature measured by the temperature sensor 30 is 3.5 ° C., the digital display 44 displays a temperature of 5 ° C. (corrected internal temperature), and the actual temperature of the central portion for accommodating the stored goods is shown. Matches

Even in the case of the same model, the temperature difference between the temperature measured by the temperature sensor 30 and the center of the storage location of the stored product is always 1.5 ° C. due to an error in each product and a difference in use condition. Not necessarily. Therefore, in the present embodiment, the temperature correction value can be adjusted even after shipment from the factory. Therefore, when the power switch 17 is turned on while the set value increasing switch 42 of the operation panel is turned on, the correction value setting routine is started. When shifting to the correction value setting routine, the temperature correction value can be increased / decreased in 0.5 ° C. units by turning on the set value increase switch 42 or the set value decrease switch 43. The correction value is displayed on the digital display 44 simultaneously with the setting. When the temperature setting switch 41 is turned on when the desired temperature correction value is displayed, the digital display 4
The correction value displayed in 4 is set as the temperature correction value. Therefore, when the power switch 17 is turned off and then turned on again, the normal temperature control routine described above is restored, and thereafter,
Based on the corrected internal temperature obtained by adding a new temperature correction value to the internal temperature detected by the temperature sensor 30, the operation control of the cooling device 2 and the internal temperature display are performed.

According to this embodiment described above, the internal temperature detected by the temperature sensor 30 is a predetermined value (this embodiment) corresponding to the temperature difference between the location where the temperature sensor 30 is installed and the storage location of the stored object. Then, the standard value is corrected by adding 1.5 ° C. That is, if the detected temperature of the temperature sensor 30 is, for example, 3.5 ° C., the corrected internal temperature is 5 ° C.
Becomes Then, the operation of the cooling device 2 is controlled based on the comparison between the corrected internal temperature and the target temperature, and if the target temperature is, for example, 5 ° C., the corrected internal temperature is 5 ° C. (the internal temperature is 3.
The operation of the cooling device 2 is controlled so that the temperature becomes 5 ° C. This means that the location of the storage is correctly maintained at the target temperature of 5 ° C. Moreover, since the temperature inside the correction chamber is displayed on the digital display 44, the temperature sensor 3
The actual temperature of the storage location of the stored object is displayed instead of the temperature of the installation location of 0, which follows the actual condition.

Further, in this embodiment, the temperature correction value is uniformly set to 1.5 ° C. at the time of factory shipment so that the user does not have to perform the correction value setting operation. Since the value can be changed by the user, there is a high degree of freedom. Moreover, in order to change the temperature correction value, the setting means for inputting the set temperature, such as the set value raising switch 42 and the set value lowering switch 43, which are originally provided, can be used, so that there is a dedicated means therefor. The structure is simple as compared with the case where the switch is provided, and the switch can be manufactured at low cost.

<Second Embodiment> FIGS. 9 to 11 show a second embodiment of the present invention. The difference from the first embodiment is that two inner boxes 51, 52 are arranged inside the main body 1 to form two independent refrigerating chambers 53, 54. The same parts as those in the first embodiment are designated by the same reference numerals, and duplicate description will be omitted. Both inner boxes 51, 52 are arranged side by side in the main body 1 with a predetermined space left and right, and a cold air passage 55 is provided so as to extend vertically between them. In the cold air passage 55, a cold air damper 56 is rotatably provided around a shaft 57 at a position where the upper opening is closed, and a solenoid 58 provided below the cold air damper 56 is in a closed state shown in FIG. It can be opened and closed between and. And, in the closed position shown in FIG.
As shown by the arrows in the figure, the cold air from the
Of the cold air passage 5 that extends vertically, and can be circulated outside of the cold air passage 5 in the open position of the cold air damper 56 shown in FIG.
5, the cold air passage to the inner box 52 on the right side is closed instead, and the cool air circulates only around the inner box 51 on the left side as indicated by an arrow in the figure. 63 is the inner box 5 on the right side.
2 is a heater for preventing supercooling provided on the left outer wall of 2.

A temperature sensor 60 is mounted in the left inner box 51 above the left inner wall via a bracket 59, and in the right inner box 52 above the right inner wall. And the temperature sensor 6 via the bracket 61
2 is attached. The electrical configuration is as shown in FIG. 10 and is similar to the configuration of the first embodiment shown in FIG. That is, the control circuit 70 includes a CPU and an A / D conversion circuit, and outputs signals from the temperature setting 1 switch 71, the setting value increasing switch 72, the setting value decreasing switch 73, the temperature setting 2 switch 74, and the temperature sensors 60 and 62. In response, the compressor 8, the solenoid 58 and the two digital indicators 44 are controlled as will be described later. Each of the above switches 71 to 7
The four and two digital indicators 44 are the operation box 16 provided on the front surface of the cooling device 2 as in the first embodiment.
The switches 71 to 74 can be freely operated by the user together with the power switch 17.
The control circuit 70 functions as operation control means for controlling the operation of the cooling device 2 in accordance with the inside temperature detected by the temperature sensors 60 and 62, as will be apparent from the description of the operation described later, and Along with the digital display 44, it also functions as an in-compartment temperature display means for displaying the temperature in accordance with the in-compartment temperature detected by the temperature sensors 60, 62, and the in-compartment temperature detected by the temperature sensors 60, 62 can be used as a reference. A predetermined value corresponding to the temperature difference between the location where the temperature sensors 60 and 62 are installed and the location where the stored goods are stored (standard is 1.5
(.Degree. C.) is added to correct the detected temperature.

Next, the operation of the second embodiment will be described. First, in order to set the target temperature of the refrigerator compartment 53, the current target temperature is displayed on one of the indicators 44 by operating the temperature setting 1 switch 71 provided on the operation panel. Then, while pressing the temperature setting 1 switch 71, the temperature displayed on one of the digital indicators 44 is changed to a desired value by the setting value increasing switch 72 or the setting value decreasing switch 73, and then the temperature setting 1 switch is set. 71 is turned on again. This sets a new target temperature for the refrigerator compartment 53. Similarly, for the other refrigerating compartment 54, the temperature setting 2 switch 74 is turned on to display the present target temperature on the other display 44. Then, while pressing the temperature setting 1 switch 74, the temperature displayed on one of the digital indicators 44 is changed to a desired value by the set value increasing switch 72 or the set value decreasing switch 73,
Then, when the temperature setting 2 switch 74 is turned on again, a new target temperature is set for the refrigerating compartment 54.

When the cooling device 2 is operated, the cool air generated in the cooler chamber 5 is blown into the cold air passage 22 to cool the inner boxes 51, 52 from the outside. When the cool air damper 56 is closed as shown in FIG. 9, the cold air cools the left and right refrigerating chambers 53 and 54. As a result, when the left refrigerating chamber 54 is sufficiently cooled, as shown in FIG. 10, the cool air damper 56 is opened and the cool air is circulated only outside the inner box 51, so that only the left refrigerating chamber 53 is cooled. Then, when this is also sufficiently cooled, the operation of the cooling device 2 is stopped.

Here, as in the above embodiment, when the temperature inside the refrigerator is detected by the temperature sensors 60 and 62, this is converted into a digital value in the control circuit 70, and the digital value becomes, for example, 1.5 ° C. The corresponding value is added. The temperature difference added by this correction is the temperature sensor 6
It is experimentally determined for each model as the temperature difference between the inner wall surfaces of the inner boxes 51, 52 in which 0 and 62 are installed and the central portion where the stored items are stored, and is set in advance at the time of factory shipment. There is. Then, when the corrected internal temperature of the refrigerating chamber 53 exceeds the target temperature set to maintain the internal cold storage, the compressor 8 of the cooling device 2 is operated to generate cold air, and the internal temperature (corrected) is generated. When the internal temperature of the refrigerator is cooled below the target temperature set as the target value, the operation of the compressor 8 is stopped. When the corrected internal temperature of the refrigerating room 54 exceeds the target temperature, the cool air damper 56 is closed and the cool air is circulated to the inner box 52 side as well. When it is opened, the circulation of cold air to the inner box 52 side is stopped. In addition, each such refrigerating room 5

When the temperature measured by 0, 62 is, for example, 3.5 ° C., the digital display 44 displays a temperature of 5 ° C., which coincides with the actual temperature of the central part containing the storage. Also in this embodiment, when the power switch 17 is turned on while the set value raising switch 72 on the operation panel is turned on, the process proceeds to the correction value setting routine, and the operation is the same as in the first embodiment. is there.

As described above, according to this embodiment as well, the operation of the cooling device 2 and the cool air damper 5 are performed based on the corrected internal temperature obtained by correcting the temperatures detected by the temperature sensors 60 and 62.
Since the operation of 6 is controlled, it is possible to correctly maintain the set target temperature at the place for accommodating the stored material. Further, since the corrected internal temperature is displayed on the digital display 44, the actual temperature of the storage location of the stored object is displayed instead of the temperature of the installation location of the temperature sensor 30, which is in line with the actual situation. become.

<Third Embodiment> FIG. 12 shows a third embodiment of the present invention. The difference from the first embodiment is that the inner box 80
A cool air discharge port 82 having a fan 81 built in is formed in the upper part of the left side wall and a cool air intake port 83 is formed in the lower part of the left side wall to introduce the cool air generated by the cooler 5 into the storage chamber inside the inner box 80. It is in the place where I tried to do it. In this case, the temperature sensor 84 is attached to the cooler 5 provided in the cooling device 2 via the bracket 85, and is located in the circulating air flow path to the cooler 5.
