The present invention relates to a temperature sensor configured to output a sensed temperature signal to a printed circuit board while sensing a temperature in the refrigerator, and in particular, to reduce the deviation between the actual temperature in the refrigerator and the sensed temperature detected by the temperature sensor to a minimum. It relates to the installation structure of the temperature sensor for kimchi storage to be able to control precisely.

In general, kimchi storage is to store / store kimchi (fresh fermented food) in a fresh state for a long time in a house or restaurant, such as an apartment that is difficult to use kimchi dog.

Such kimchi storage is to be stored refrigerated fermented food in a uniform state or to be aged for a certain period of time according to the user's preferences, in order to refrigerated or mature the fermented foods to the user's preference. Temperature sensors that sense the temperature played an important role.

That is, when the temperature sensor senses the temperature in the refrigerator and outputs a temperature signal corresponding to the sensed temperature to the printed circuit board, the display unit displays the temperature in the refrigerator detected by the temperature sensor. By operating the operation unit to set the temperature in the refrigerator to a temperature desired by the user, it is possible to refrigerated or mature the fermented food stored in the refrigerator.

On the other hand, the temperature sensor installation structure of the first embodiment according to Utility Model Registration Application No. 97-18442, filed by Mando Machinery Co., Ltd., filed on July 12, 1997, as shown in FIGS. 1 and 2, an outer container 601. The inner cylinder 603 equipped with the inner chamber 602 is installed to be fixed by the heat insulating material 604, and a condenser 605 is disposed between the outer container 601 and the inner cylinder 603. In addition to being fixed by the heat insulating material 604 to contact the inner surface of the 601, the evaporator 606 is fixed by the heat insulating material 604 to contact the outer peripheral surface of the inner cylinder 603, the outer bottom of the inner cylinder 603 The heater 607 is provided in the site | part which contacts a surface so that position may be fixed by the heat insulating material 604.

In addition, a sensor pipe 608 of a predetermined length is inserted into a lower portion of the inner cylinder 603 from a machine room 609 partitioned by a heat insulating material 604 to a lower side of the interior 602 so that one end is connected between the heaters 607. The other end is fixed by the heat insulating material 604 in contact with the outer bottom surface of the inner cylinder 603 while being positioned to protrude into the machine room 609.

In addition, the inside of the sensor pipe 608 is fixed by the position of the sensor clip 612 elastically deformed in the state in which the temperature sensor 611 connected to the wire 610 is inserted in contact with the outer bottom surface of the inner cylinder 603. It is installed if possible.

However, according to the conventional structure of the temperature sensor 611 according to the first embodiment as described above, the temperature sensor 611 is inserted into the sensor pipe 608 and then fixed using the sensor clip 612. When installing or replacing the temperature sensor 611 fixedly installed in the sensor pipe 608, there is a problem that the work performance is degraded because the operator has to work uncomfortable due to the narrow machine room 609.

In addition, the temperature sensor 611 is installed so as to contact the outer bottom surface of the inner cylinder 603 by the sensor clip 612 is fixed by its own elastic force inside the sensor pipe 608, the impact from the outside When delivered, the sensor clip 612 is gradually separated from the sensor pipe 608, thereby the temperature sensor 611 is not in full contact with the outer bottom surface of the inner cylinder 603, the interior Since a large temperature deviation is generated between the actual temperature of 602 and the sensed temperature detected by the temperature sensor 611, there is a problem in that the temperature of the interior 602 cannot be accurately controlled.

In addition, since the interior of the machine chamber 609 and the sensor pipe 608 communicate with each other through one end, the high temperature generated from the surface of the compressor when the compressor (not shown) installed in the machine chamber 609 is driven. Radiant heat is introduced into the sensor pipe 608 to affect the temperature sensor 611, so that the temperature of the interior 602 displayed on the display unit is displayed higher than the actual interior 602 temperature, so that the user There was also a problem in that the temperature of the interior 602 could not be accurately controlled.

In addition, since the temperature sensor 611 is installed between the array structures of the heaters 607, the ripening temperature of the inside of the gourd 602 at the time of ripening of the fermented food stored in the inside of the gourd 602 is easily available in a short time. Although it can be detected, when the refrigerated storage of the fermented food has a problem that takes a long time until the temperature sensor 611 easily detects the refrigerated storage temperature of the inside 602.

In order to solve such a problem, since the set temperature at the time of maturation and the set temperature at the time of refrigeration must be set in the microcomputer (not shown) by a program of a different temperature zone, the problem that workability becomes cumbersome still remains.

In addition, the temperature sensor installation structure of the second embodiment according to Patent Application No. 97-32404, filed by Mando Machinery Co., Ltd., filed on July 12, 1997, is illustrated in FIGS. An inner cylinder 703 having an inner chamber 702 is provided to be fixed in position by a heat insulating material 704, and a condenser 705 is disposed between the outer container 701 and the inner cylinder 703. It is fixedly installed by the heat insulating material 704 to contact the inner surface of the evaporator 706 is fixed by the heat insulating material 704 so as to contact the outer peripheral surface of the inner cylinder 703, and the outer bottom surface of the inner cylinder 703 The heater 707 is provided in the contacted part so that the position may be fixed by the heat insulating material 704.

In addition, between the arrangement of the evaporator 706, the temperature sensor 708 is configured to sense the temperature of the interior 702 and output a temperature signal corresponding to the detected temperature to the printed circuit board. It is fitted to the member 710 and is installed so that the position may be fixed by the heat insulating material 704.

Here, the temperature sensor cover member 710 is formed in the shape of the C-shaped in the site where the two evaporator clip portion 711 to be fitted to the evaporator 706 are spaced from each other, between the evaporator clip portion 711 The sensor clip portion 712 into which the temperature sensor 708 is fitted is integrally formed.

Accordingly, when the temperature sensor 708 is inserted into the sensor clip portion 712, and then the evaporator 706 is inserted into each evaporator clip portion 711, the temperature sensor 708 is arranged in the evaporator 706. When the structure is installed while contacting the outer circumferential surface of the inner cylinder 703 via the temperature sensor cover member 710, and then foaming the heat insulating material 704 in the outer container 701 and the inner cylinder 703, the The temperature sensor cover member 710 is fixed by the heat insulating material 704.

Therefore, according to the conventional temperature sensor installation structure according to the second embodiment, the temperature sensor 708 is easily installed by the temperature sensor cover member 710 that is fitted and fixed to the evaporator 706, the temperature sensor 708 Work performance is improved during installation and replacement of the work, and even if the shock is transmitted from the outside, the temperature sensor 708 is always in contact with the inner cylinder 703, as well as the temperature sensor 708 regardless of the radiant heat of the compressor Since the temperature of 702 can be controlled, most of the problems according to the first embodiment can be solved.

However, because the temperature sensor 708 is installed between the arrangement of the evaporator 706, that is, the temperature sensor 708 is located at a distance from the heater 707 at a position close to the evaporator 706. Due to being installed at a location, the refrigerated storage temperature of the inside of the refrigerator 702 can be easily detected in a quick time when refrigerated storage of the fermented food stored in the inside 702, the temperature during the storage of the fermentation of the fermented food There was a problem that it takes a long time before the sensor 708 to easily detect the aging temperature of the interior 702.

In order to solve such a problem, since the set temperature at the time of maturation and the set temperature at the time of refrigeration must be set in the microcomputer (not shown) by a program of a different temperature zone, the problem that workability becomes cumbersome still remains.

As an example, assuming that the optimum temperature of the inside of the refrigerator 702 at aging is 23 ° C. and the optimum temperature at refrigeration is 0 ° C., and the distance between the evaporator 706 and the temperature sensor 708 shown in FIG. 3 is a reference distance. When the user refrigerates and stores the chamber 702, the temperature detected by the temperature sensor 708 and displayed on the display unit is displayed at 0 ° C. which is the same as the optimum temperature of the chamber 702. At this time, since the distance between the heater 707 and the temperature sensor 708 is installed farther than the reference distance between the evaporator 706 and the temperature sensor 708, the temperature detected by the temperature sensor 708 and displayed on the display is high. Only when the temperature is lower than the optimum temperature of 702 (approximately 15 ° C.), the aging temperature of the actual chamber 702 maintains the optimum temperature of 23 ° C.

In addition, the temperature sensor 707 makes a point contact with the outer circumferential surface of the inner cylinder 703, so that the temperature of the interior 702 is only detected by the temperature sensor 707 making a point contact, the temperature sensor 707 There was also a problem that the temperature sensing function of the) is reduced.

In addition, the temperature sensor cover member 710 is fixed to the position by the foaming of the heat insulating material 704 in the state that is simply fitted to the evaporator 706, the stronger the foam pressure of the heat insulating material 704 is the temperature sensor cover member ( 710 is fixed to a position that is moved from the initial position to another position, thereby allowing the temperature sensing region of the temperature sensor 707 to sense the temperature at a different region than the temperature sensing region at the first test. Therefore, a severe deviation occurs between the actual temperature of the chamber 702 set in the control unit based on the result of the test and the temperature of the chamber 702 detected by the temperature sensor 707, so that the temperature sensor 707 functions. There was also a problem that can not perform properly.

In addition, since the heat insulating material 704 is foamed between the gaps of the temperature sensor cover member 710 during the foaming of the heat insulating material 704 and hardens on the surface of the temperature sensor 707, the function of the temperature sensor 707 is deteriorated. There was also a problem.

Therefore, the present invention has been made to solve all the problems described above, by installing a temperature sensor between the evaporator and the heater, when the storage of the fermented food stored in the fermentation or refrigerated storage at the set temperature and refrigerating during aging The purpose is to provide the installation structure of the temperature sensor for kimchi storage to improve the workability by setting the set temperature of the same temperature program in the microcomputer.

In addition, by installing the temperature sensor to make a surface contact with the outer circumferential surface of the inside of the kimchi storage temperature sensor for improving the temperature sensing function of the temperature sensor by allowing the temperature in the interior to be sufficiently detected by the temperature sensor The purpose is to provide an installation structure.

In addition, the temperature sensor cover member is attached to the outer circumferential surface of the inner cylinder by the fixing means in the state that the temperature sensor cover member is fitted to the evaporator, and then fixed by a heat insulating material, so that the movement of the temperature sensor cover member is secured by the fixing means even if the foam pressure of the heat insulating material is strong. This makes the final temperature sensing region of the temperature sensor the same as the temperature sensing region at the time of the first test, thereby reducing the temperature deviation generated between the actual temperature in the chamber and the interior temperature detected by the temperature sensor. By preventing it in advance, the object is to provide an installation structure of the temperature sensor for kimchi storage to fully utilize the function of the temperature sensor.

In addition, by attaching the temperature sensor cover member to the outer circumferential surface of the inner cylinder so as to be completely sealed by the fixing means, by preventing the thermal insulation material from foaming between the gap of the temperature sensor cover member when foaming the thermal insulation material, the function of the temperature sensor is reduced. The purpose is to provide an installation structure of the temperature sensor for kimchi storage to be prevented.

The present invention for achieving the above object, the temperature sensor to detect the temperature in the high temperature sensor cover member is detachably fitted to the temperature sensor cover member, the temperature sensor cover member is fitted to the evaporator fixed temperature sensor for kimchi storage. In the installation structure of the evaporator so that the temperature sensor cover member is fitted into the evaporator wound at the bottom of the evaporator wound on the outer peripheral surface of the inner cylinder and fixed, the temperature sensor detects the ripening temperature and the refrigerated storage temperature in the refrigerator without deviation from the actual temperature. And is installed between the heater.
