The present invention relates to a door opening detection structure of the kimchi storage, and more particularly, by mounting the opening and closing detection unit to inform the opening state of the door in the hinge region, overcoming the disadvantages of appearance, while reducing the number of parts It relates to a door open detection structure of a kimchi storage to reduce installation costs.

In general, refrigerators used in homes have a short shelf life because the temperature inside the refrigerator changes drastically when the door is opened and closed frequently.

Moreover, due to the characteristics of kimchi, a proper temperature for maintaining a suitable ripening state is lower than that of general refrigerated foods, so it is difficult to store it in a general refrigerator for a long time, so it is used separately.

In other words, recently, Kimchi fermentation has become active and fermentation of kimchi storage for a certain period of time or refrigerated storage has become active.

The kimchi storage is equipped with a temperature control suitable for ripening and long-term storage of kimchi so that you can enjoy the taste of fresh kimchi according to the taste of the user by using a heater and a refrigeration system.

As shown in Figure 1, the kimchi storage, the storage compartment 300 and the machine room (not shown) is formed therein so as to open and close the main body 100 and the opening of the storage chamber 300 sidewall foamed with a heat insulating material The main body 100 has a door 200 coupled through a hinge 210 provided at the top of the rear surface.

In the machine room, a compressor and a condenser, not shown, are provided as cooling means. An outer wall of the storage room 300 is provided with an evaporator, not shown, which encloses the storage room 300 in a ring shape.

Accordingly, when the refrigerant is compressed at a high temperature and high pressure in the compressor, the compressed refrigerant is condensed into a liquid phase in the electrolytic condenser, and then transferred to the evaporator through an expansion valve or a capillary tube.

Then, the evaporator forms cold air into the storage chamber 300 by using latent heat according to evaporation of the refrigerant.

By the way, the conventional kimchi storage of the type of the door 200 is mounted on the upper end of the main body 100 to rotate the opening and closing of the storage chamber 300, the interior of the door 200 is foamed with a heat insulating material of the door 200 It can be seen that the weight is quite high.

The reason why the weight of the door 200 is heavy is to increase the sealing property in order to prevent the cool air in the storage chamber 300 from escaping to the outside through the space between the main body 100 and the door 200. One example is this.

The reason why the weight of the door 200 is heavy is to prevent the cool air in the storage compartment 300 from escaping to the outside through the space between the main body 100 and the door 200, so that the door 200 is stored in the storage compartment. If the opening of the 300 is closed, it is advantageous to keep the inside of the storage chamber 300 cool.

However, if the door 200 is left in an open state due to the circumference of the consumer, the cold air in the storage compartment 300 is forced to escape to the outside, thereby reducing the freshness of the stored kimchi.

Therefore, in the conventional kimchi storage including the conventional refrigerator, the opening and closing detection unit for detecting the opening and closing state of the door is provided to display the open state of the door to the outside.

Although not shown, a normal opening / closing detecting unit is provided with a magnetic body mounted on the inner surface or the side of the door, and provided in the main body at a position corresponding to the magnetic body to magnetically open and close the door based on magnetic contact with and release of the magnetic body. It consists of a magnetic sensor that transmits.

Accordingly, when the door is opened, the magnetic material is separated from the magnetic sensor, so that the open state of the door is sensed by the magnetic sensor, and the detected signal is transmitted to the outside through a separate means.

However, it is not easy to provide a magnetic material on the door and each of the magnetic sensors installed on the main body, which is not an easy task. Therefore, the installation cost increases because the number of parts is required.

In addition, since the magnetic body and the magnetic sensor are mounted on the door and the main body, there is a drawback that the appearance is not good.

Therefore, if the opening and closing detection unit is mounted on the hinge region by adopting the technique of No. 2003-16149 (filed on March 3, 2003), which has been filed by the present applicant, it may overcome an unsightly disadvantage and the number of parts The installation cost can be reduced by reducing the cost.

In addition, if the operation of the corresponding parts are controlled to be turned off when the door is opened, it is possible to suppress the formation of unnecessary cold air and reduce power consumption.

The present invention has been made in order to easily determine the door opening state in the kimchi storage applying the hinge assembly filed by the present applicant as described above, the object of the present invention, the opening and closing detection unit to determine the door opening state hinge region In order to overcome the disadvantages of the appearance, while providing a door open detection structure of the kimchi storage to reduce the number of parts to reduce the installation cost.

The fixing member 31 is formed in an elongated rod shape and has a shaft hole 31a formed therein so that the fixing shaft 34 can be inserted along the axial direction.

Then, the outer side of the lower hinge receiving portion 12 is inserted into the rail 13 formed in the center (12a) disposed in the center of the slot-shaped fastening portion 31b to prevent rotation in the lower hinge receiving portion 12 ) Is formed.

In addition, a plurality of ribs 31c are formed between the coupling parts 31b at intervals along the longitudinal direction of the fixing member 31.

One of the lower hinge accommodating parts 12 disposed outside 12b is provided with a separate cap 25 to cover the hinge assembly 30.

At this time, when manufacturing the fixing member 31 in the shape shown above, there is an advantage that can reduce the material cost required for the manufacturing of the fixing member 31.

However, it is not necessary to employ the fixing member 31 having the rib 31c formed therein, and various types of fixing members 31 shown and described in the patent application No. 2003-16149 filed by the present applicant ) Can be employed.

Both ends of the fixing member 31 are provided with a pair of driven parts 31d and 31'd which are recessed inwardly with respect to the vertical plane of both ends and whose shape is inclined like a spiral gear.

The driven parts 31d and 31'd are rotatably engaged with the rotating parts 32a and 32'a of the rotating members 32 and 32 ', which will be described later.

Rotating members 32 and 32 'provided at both ends of the fixing member 31 include rotating parts 32a and 32'a formed at one end facing the fixing member 31, and rotating parts 32a and 32'a. It is composed of a body portion (32b, 32'b) having a larger diameter than).

The rotating parts 32a and 32'a have a gear structure formed of a spiral inclined surface that is substantially similar to the driven parts 31d and 31'd of the fixing member 31.

Therefore, when the rotating parts 32a and 32'a rotate in one direction (opening of the door 20) with respect to the driven parts 31d and 31'd, the rotating parts 32a and 32'a and the driven part Protruding portions 31d and 31'd abut each other so that the rotating members 32 and 32 'may be spaced apart from the fixed member 31.

Slotted fastening portions 32c and 32'c are also formed outside the body portions 32b and 32'b.

The fastening portions 32c and 32'c formed on the body portions 32b and 32'b are respectively fitted to the rails 23 formed on the inner surface of the upper hinge accommodation portion 22 to rotate the members 32 and 32 '. It is possible to rotate in the forward and reverse direction in conjunction with the rotation of the door 20.

In addition, shaft holes 32d and 32'd through which the fixed shaft 34 passes are formed inside the body parts 32b and 32'b and the rotating parts 32a and 32'a, respectively.

The elastic members 33 and 33 'are inserted into and coupled to the pair of rotating members 32 and 32' and the body parts 32b and 32'b, respectively.

Here, the elastic members 33 and 33 'are employed to constrain the rotational state of the rotating members 32 and 32', that is, the rotational state of the door 20 by compression springs, which will be described later.

The fixed shaft 34 is inserted along the shaft holes 31a, 32d, and 32'd of the fixing member 31 and the rotating members 32 and 32 'so that the fixing member 31 and the rotating members 32 and 32' are fixed. In addition to supporting the coupling between the (3) and restricts the flow of the elastic member (33, 33 ').

On the other hand, as shown in Figure 6 and 7, the opening and closing detection unit 60 according to the present invention is formed in the outer surface of any one of the body portion 32b of the pair of rotating members (32, 32 ') It consists of a depression 62, and a sensor portion 64 for generating a signal by interacting with any one of the body portion 32b and the depression 62.

In the present embodiment, the recess 62 is provided in the body portion 32b of the rotating member 32 disposed on the left side of FIG. 5, but the body portion 32'b of the right rotating member 32 '. It is also possible to provide the depression 62 in the.

The sensor unit 64 is elastically protruded with respect to the sensor body 64a and the sensor body 64a which are provided in the main body 10 by a separate bracket (not shown), and an upper end receiving portion 22 of which the end thereof is provided. ) And an elastic protrusion 64b which is exposed to the inside of the door 20 and generates a signal to the sensor body 64a by interacting with any one of the body portion 32b and the depression 62 according to the open / closed state of the door 20. .

Thus, as shown in FIG. 6 schematically, when the door 20 is closed of the storage compartment 10a, the elastic protrusion 64b is elastically relaxed (in the original state) in the depression 62 so that the sensor The closing state signal of the door 20 is transmitted to the body 64a.

However, as shown in FIG. 7, when the door 20 is opened with respect to the storage compartment 10a, the elastic protrusion 64b is pressed by the side of the body portion 32b and elastically contracted so that the sensor body The open state signal of the door 20 is transmitted to 64a.

When the sensor unit 64 generates the open state signal of the door 20 as described above, the controller 50 which has received this information indicates that the door 20 is opened through the display unit 55 (see FIG. 8).

In this case, the display unit 55 may be one of a lamp for transmitting a visual signal and a buzzer for transmitting an audio signal.

If the display unit 55 is to be employed in the form of the lamp, the display operating unit 11 may be provided integrally. If the display unit 55 is to be employed in the form of the buzzer, the main body 10 and the door 20 may be used. It can be mounted separately in either.

At this time, the buzzer may be a normal ringtone or a bell.

However, in addition to this, the display unit 55 may further include a voice guide unit 56 (see FIG. 8) for guiding a voice that the door 20 is directly opened.

That is, as shown in FIG. 6, when the door 20 is closed of the storage compartment 10a, the controller 50 receiving the signal from the open / close detection unit 60 is the voice guide unit 56 of the display unit 55. By operating), the voice "door 20 is closed" may come out.

On the contrary, as shown in FIG. 7, when the door 20 is opened with respect to the storage compartment 10a, the controller 50 receiving the signal from the open / close detection unit 60 is the voice guide unit 56 of the display unit 55. ), The voice of "now, the door 20 is open" may come out.

Of course, in addition to this, a predetermined program 56a (see Fig. 8) is set in the voice guide unit 56, and when the door 20 is opened, the voice "now the door 20 is open" is sent to the outside. After 10 seconds or so, it will be more effective if the voice "Please close the door 20 quickly" is repeated.

In addition, if the program 56a is further set in the voice guide unit 56, the following effects can also be created.

For example, it was explained that the hinge portion 15 of the present invention employs the one filed by the applicant with the patent application No. 2003-16149.

Therefore, the attempt was made to prevent injuries to the back of the hand due to the sudden closure of the heavy door 20.

However, this is merely a mechanical buffer, and the fact that the elasticity of the elastic members 33 and 33 'is not able to be fully digested is true.

Therefore, when the door 20 is opened by setting a predetermined program 56a in the voice guide unit 56, the door 20 is opened. Do not place your hand on the upper portion of the storage compartment 10a. If a voice such as "Or," or "Door (20) is closed tightly, please pay attention," please let the user to pay more attention can provide an effect that can prevent accidents in advance There will be.

This is briefly described with reference to FIG. 9 as follows.

First, in the state in which the voice guide unit 56 is waiting (S11), the control unit 50 receiving the signal of the open / close detection unit 60 determines whether the door 20 is open (S12).

When the door 20 is opened, the voice guide unit 56 allows the above-described various kinds of flow out (S13).

Then, after a predetermined time passes and the control unit 50 receives the signal of the opening and closing detection unit 60 determines whether the door 20 is closed (S14), when it is confirmed that the door 20 is closed The voice guide part 56 guides the voice to the voice that the door 20 is closed by the above-described method (S15).

On the other hand, the control unit 50 for operating the display unit 55 by the signal of the opening and closing detection unit 60, in addition to the control according to the opening and closing state of the door 20, as shown in Figure 8, the compressor 51 Also, the operation of the heater 53, the cooling fan 52, and the sterilization lamp 54 may be controlled.

That is, even though the door 20 is open, if the components for forming cold air or other parts operate, cold air is formed unnecessarily and power consumption is inevitably increased.

Thus, when the open state of the door 20 is sensed by the opening / closing detection unit 60, the control unit 50 transmits it to the display unit 55, while the compressor 51, the heater 53, and the cooling unit are cooled. The operation of the fan 52 and the sterilization lamp 54 is turned off.

If the kimchi storage is not provided with a sterilization lamp 54 for sterilization inside the storage chamber 10a, the sterilization lamp 54 may be excluded from the configuration of FIG. 8.

Thus, according to the present invention, by mounting the opening and closing detection unit 60 in the hinge portion 15 region to overcome the disadvantages of appearance unsatisfactory, it is possible to reduce the installation cost by reducing the number of parts.

In addition, it is possible to prevent the safety accident in advance by transmitting the opening and closing state of the door 20 by voice, and to control the operation of the corresponding parts to be off (OFF) when opening the door 20 to form unnecessary cold air It can be suppressed and power consumption can be reduced.

In the above-described embodiment, when the elastic protrusion 64b is disposed in the depression 62, when the door 20 is in a closed state and is pressurized and contracted by the body portion 32b, the door 20 is closed. Although described as being in an open state, they may be configured oppositely.

As described above, according to the present invention, the opening and closing detection unit is installed in the hinge region, thereby overcoming an unsightly disadvantage, and reducing the number of parts, thereby reducing the installation cost.                     

In addition, according to the present invention, it is possible to prevent the safety accident in advance by transmitting the opening and closing state of the door by voice, and to control the operation of the corresponding parts when the door is opened (OFF) to suppress the formation of unnecessary cold air. And it can reduce the power consumption.
