Description

Natural refrigeration system and method for preparing pickles for the winter}

The present invention relates to a refrigeration system, and more particularly, to a refrigeration system for the storage and ripening of kimchi in winter.

A typical refrigerator includes a refrigerator compartment, a freezer compartment, and a refrigerant circulation system for cooling and maintaining them at a constant temperature.

In particular, the kimchi refrigerator is only a more diversified function of the refrigerating compartment of a general refrigerator, especially for kimchi storage and ripening. That is, reinforcement of heat insulation treatment to prevent the kimchi taste from changing, and temperature control for fast ripening course.

However, such a kimchi refrigerator has a problem in that it is not easy to carry because it is very heavy as the weight is more than 80kg depending on its capacity. In addition, there is a problem in that it is inconvenient to install in a narrow room with a large volume. And most of all, the high cost of incorporating the refrigerant circulation system and the surrounding controllers leads to the fact that consumers have to purchase them at a very high price, and consume considerable power to run the refrigerant circulation system and drive the controller to maintain the refrigerator compartment temperature. Therefore, there is a problem that the maintenance cost is too large.

Therefore, the technical problem to be achieved by the present invention is a natural refrigeration system for winter kimchi kimchi that can maintain the refrigeration temperature without power, is light, and can be easily installed in an inconspicuous place, such as the corridor of the home or the utility room And a method thereof.

The natural refrigeration system according to the present invention for achieving the above technical problem, the refrigerator compartment having a door and a hole; An opening and closing device attached to the refrigerating compartment hole and selectively introducing or blocking external air into the refrigerating compartment according to a logic state of an opening and closing control signal; A temperature sensor that detects a temperature of the outside air and outputs an outside air temperature value; And a control device for comparing the external air temperature value with a user set temperature range and generating the open / close control signal in response to the comparison result. The natural refrigeration system further comprises an external air induction pipe for inducing the inflow of external air between the refrigerating compartment hole and the outdoors. The natural refrigeration system further comprises a blower for selectively introducing external air into the external air induction pipe or blocking the inflow according to a logic state of the open / close control signal. The temperature sensor is characterized in that provided in the outside air induction pipe.

According to another aspect of the present invention, there is provided a natural refrigeration method, the method including selectively introducing external air into the refrigerating compartment or blocking inflow according to a logic state of an open / close control signal; Sensing the temperature of the outside air and outputting an outside air temperature value; And comparing the external air temperature value with a user set temperature range and generating the opening / closing control signal in response to the comparison result.

In order to fully understand the present invention, the operational advantages of the present invention, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings which illustrate preferred embodiments of the present invention and the contents described in the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote like elements.

1 is a block diagram illustrating a natural refrigeration system 100 according to an embodiment of the present invention. Referring to FIG. 1, the natural refrigeration system 100 includes a refrigeration room 110, an open and close apparatus 120, an outer air guide pipe 130, and a blower. an air blower 140, a temperature sensor 150, and a controller 160.

The refrigerating chamber 110 is a space for storing and ripening kimchi kimchi in winter season. The refrigerating chamber 110 may be used to store various kinds of foods to maintain kimchi or freshness. For example, when the refrigerator in the home of the winter season is full of other foods and the storage space is insufficient in the refrigerator, fruits or vegetables may be stored in the refrigerator compartment 110. The refrigerating compartment 110 is provided with a door (door) for putting in and out of the thing to be stored (see Figs. 2 and 3), and has a hole (hole) for installing the opening and closing device 120. The refrigerating compartment 110 may be installed in a veranda or a multipurpose room in the home, and the cold refrigerating compartment 110 at a low enough temperature to store kimchi or various fresh foods without supplying power for refrigerant circulation using cold air in winter. It was proposed to help maintain it. Therefore, in order to keep the cold air flowing into the refrigerating compartment 110 from the outside for a long time, the structure material of the refrigerating compartment 110 must be sufficiently insulated.

The opening and closing device 120 is attached to the opening of the refrigerating compartment 110, and selectively introduces outside air into the refrigerating compartment 110 or blocks inflow according to a logic state of the opening and closing control signal generated by the control device 160. Let's do it. That is, the opening and closing device 120 receiving the opening and closing control signal from the control device 160 mechanically opens and closes a predetermined shutter. For example, if the open / close control signal is in a first logic state (logic low state), the predetermined shutter is closed, and thus external air cannot flow into the refrigerating chamber 110. In addition, when the open / close control signal is in a second logic state (logic high state), the predetermined shutter is opened and thus external air may be introduced into the refrigerating chamber 110. One of ordinary skill in the art can easily implement such an electrical circuit.

The external air induction pipe 130 induces inflow of external air between the hole in the refrigerating chamber 110 and the outdoors. FIG. 2 is a first application of the natural refrigeration system 100 of FIG. 1. As shown in FIG. 2, the purpose of using the external air induction pipe 130 is to consider that the refrigerating chamber 110 is installed in a veranda or a utility room of a home, and between the refrigerating chamber 110 and the location where external air may contact. Used when there is some distance to. That is, the outside air induction pipe 130 guides the outside air to the refrigerating chamber 110 installed in the room.

The blower 140 forcibly introduces or blocks inflow of external air to the external air induction pipe 130 according to a logic state of the opening / closing control signal generated by the control device 160. The blower 140 is composed of a propeller (not shown) and a motor (not shown) to rotate the blower 140. A motor (not shown) provided in the blower 140 selectively introduces external air into the external air induction pipe 130 or blocks inflow according to a logic state of the open / close control signal. For example, when the open / close control signal is in a first logic state (logic low state), the motor (not shown) provided in the blower 140 stops operation, and thus, external air flows into the external air induction pipe 130. It is not forced to flow. In addition, when the open / close control signal is in the second logic state (logic high state), the motor (not shown) provided in the blower 140 operates to thereby force external air to flow into the external air induction pipe 130. . As shown in FIG. 2, the blower 140 is used to quickly introduce cold air outside the winter season into the refrigerating chamber 110. This is optionally used depending on the user. In particular, when the external air induction pipe 130 and the refrigerating chamber 110 is far from the need to force the inflow of external air, the blower 140 is used.

The temperature sensor 150 detects the temperature of the outside air and outputs an outside air temperature value. Accordingly, the control device 160 compares the external air temperature value output from the temperature sensor 150 with a user set temperature range, and generates the open / close control signal in response to the comparison result.

For example, considering that Korea's winter temperature is about 10 degrees below zero and around 10 degrees, the temperature range set by the user is preferably minus 5 degrees to 10 degrees to maintain the freshness of Kimchi for a long time. . That is, when the user set temperature range is set to minus 5 degrees to 10 degrees, if the external air temperature value is below 5 degrees or less than 10 degrees, the opening / closing control signal is in a first logic state. Further, in this case, if the external air temperature value is between -5 degrees Celsius and 10 degrees image, the open / close control signal is in a second logic state. Here, the lower limit of the user set temperature range is required because the food in the refrigerator compartment 110 may be frozen when the temperature of the refrigerator compartment 110 is too low, which may adversely affect the temperature. In addition, the upper limit of the user-set temperature range is required because the food in the refrigerator compartment 110 may be easily spoiled and may not be stored for a long time when the temperature of the refrigerator compartment 110 is too high. The user set temperature range may be set differently according to a case where the winter season is long and cold or according to different storage purposes of the user.

Since the temperature sensor 150 senses the temperature of the outside air, the temperature sensor 150 should be installed in contact with the outside. In particular, when the external air induction pipe 130 is used, as shown in Figure 2, it is preferable that the temperature sensor 150 is provided in the external air induction pipe 130.

3 is a second application of the natural refrigeration system 100 of FIG. 1. 3 is an example of a case where the natural refrigeration system 100 according to an embodiment of the present invention is installed in a cold place close to the outside air, such as apartment corridor, light or kitchen in rural countryside. In this case, the temperature sensor 150 may be provided at any position on the outer wall of the refrigerating chamber 110 or in the control device 160. In the case of FIG. 3, the outside air flows directly through the opening and closing device 120 without using the outside air induction pipe 130.

As described above, in the natural refrigeration system 100 according to an embodiment of the present invention, the cold air outside the winter season to the cold room 110 through the external air induction pipe 130 to a certain low temperature When the temperature of the refrigerating chamber 110 rises, the switchgear 120 is automatically closed under the control of the controller 160 so that the temperature of the refrigerating chamber 110 is no longer increased.
