Description

Wine refrigerator {Wine refrigerator}

The present invention relates to a wine refrigerator, and more particularly, to provide reliability for safe operation by appropriately dealing with all problems caused by a failure of a corresponding part or a malfunction of a user and an installation environment. The present invention relates to a wine refrigerator, which allows to keep the product and the stored wine safe.

Previously, conventional refrigerators having a refrigeration cycle circulated to a compressor, a condenser, and an evaporator all had a refrigerating function to uniformly store various drinks, kimchi, side dishes, etc. in addition to the freezing function of freezing.

However, based on the fact that the storage conditions of kimchi, side dishes, and cosmetics are different from each other in addition to a simple refrigerator in the recent years, where the standard of living is improved and consumers' desires and requirements are increased, the food or the goods The release of a functional refrigerator that can be stored alone is becoming active.

For example, kimchi refrigerators that can be stored for a long time while maintaining the freshness of kimchi, side dishes refrigerators that can remove unpleasant odors of existing refrigerators by storing only various side dishes, and retinol collagen such as retinol collagen It is a small-sized cosmetic refrigerator that keeps functional products and skins at the most suitable temperature of 10-15 ° C. and places them on a dressing table.

Of course, in addition to these functional refrigerators, wine refrigerators that can be stored exclusively for wine are also actively manufactured as functional refrigerators. The so-called wine (Wine) is a fruit wine made by fermenting grapes or grapes, and is often used as a substitute for accompaniment at meals.

As such, wine is a liquor that can be commonly found in the surroundings, like ordinary drinks, and it is common to pay considerable attention to storage because its taste and quality change depending on its storage conditions. However, unlike the past, wine refrigerators as functional refrigerators have emerged, making wine storage easier.

The conventional wine refrigerator, which has already been prepared by the present applicant, considers the characteristics of the wine sensitive to vibration as much as possible, thereby allowing the wine to be stored in an environment suitable for wine and without vibration.

The wine refrigerator, which replaces the existing refrigeration cycle, adopts the so-called Peltier element, a semiconductor thermoelectric element, which greatly reduces vibration and reduces noise to about 22.7 decibels (dB).

In addition, due to the nature of the temperature-sensitive wine, the temperature of the wine cellar can be adjusted in units of 1 ℃, and three or more types of temperature can be selected according to the type of wine. In addition, it is possible to implement the optimization of humidity, and has a structure that can maintain the wine's unique taste and aroma for a long time through the double UV blocking glass.

To this end, a typical wine refrigerator has a temperature control unit for controlling the temperature of the wine cellar as well as preventing the temperature rise of the heat dissipation unit. When the temperature control unit is above a certain temperature, the power is turned off. Is on.

By the way, in such a conventional wine refrigerator, it is true that there is no protection operation other than this simple control. Therefore, if any one of many parts is broken, or a malfunction such as a fan operation, a sensor operation, a heat dissipation unit overheating, or a PCB overheating occurs due to a malfunction of a user or a condition of an installation environment, It is true that there is no countermeasure.

Therefore, it is possible to appropriately deal with all the problems caused by the failure of the corresponding parts or due to the user's malfunction and the installation environment, to give reliability for safe operation, and to keep the product and storage wine safely. It is urgent to develop technology to make it possible.

Accordingly, an object of the present invention is to appropriately deal with all the problems caused by the failure of the corresponding parts or the user's malfunction and the installation environment, and to provide reliability for safe operation. A wine refrigerator is provided to keep your back safe.

The cooling unit 20 is provided in a space formed on the rear wall of the main body 10 so that cold air flows along the first and second wine storage chambers 11 and 12 and the Peltier element is applied as a cooling heat exchanger. 21 and first and second cooling units provided on the rear surfaces of the first and second wine storage chambers 11 and 12 to blow cool air from the cooler 21 into the first and second wine storage chambers 11 and 12. The radiators 23 and the radiators 23 provided on the rear surfaces of the fans 22a and 22b and the main body 10 to radiate the first and second wine storage chambers 11 and 12. It includes a plurality of heat dissipation fan 24 mounted on the top to double the heat dissipation of the radiator (23).

The plurality of temperature detecting members 30 are provided at positions adjacent to the first and second cooling fans 22a and 22b to detect the temperature in the first and second wine storage chambers 11 and 12. A heat dissipation sensor 33 provided below the heat dissipator 23 to detect the temperature of the heat dissipation part to prevent the sensors 31 and 32 and the temperature of the heat dissipator 23 from rising and damaging the cooler 21; The outside air sensor 34 is provided on one side of the rear surface and measures the temperature of the outside air so that the controller 50 can control the heat radiating fan 24 by comparing the data with the heat radiating sensor 33.

On the other hand, the PCB substrate 40 is supplied with the power applied to the wine refrigerator to distribute the voltage while the cooling unit 20 and the temperature and humidity for the control of the temperature, humidity and other in the first and second wine storage chamber (11, 12) The control part 50 which controls each structure of the temperature detection member 30 individually is mounted.

As described in detail below, the controller 50 is electrically connected to the LCD display unit 18 described above so that each control state (including an error state) is displayed on the display unit 18. In addition, the controller 50 is connected to the alarm generator 60 which displays an error state generated in any one of the cooling unit 20 and the temperature detecting member 30 to the outside.

In the wine refrigerator having such a configuration, the controller 50 individually controls the corresponding components among the cooling unit 20 and the temperature detecting member 30 will be described with reference to FIGS. 3 and 4A to 4E.

FIG. 4A is a control flow diagram showing the control unit 50 controlling the first and second cooling fans 22a and 22b and the heat radiating fan 24. Before describing FIG. 4A, the controller 50 controls the first and second cooling fans 22a and 22b as follows.

First, when an error occurs in only one of the first and second cooling fans 22a and 22b in one of the high speed mode HIGH and the low speed mode LOW, the controller 50 displays the generated error state. 18). Then, the first and second cooling fans 22a and 22b are controlled to be switched to another mode that can be partially operated (this is called emergency operation). That is, if the high speed mode HIGH is an error, the operation is performed in the low speed mode LOW, and if the low speed mode LOW is an error, the high speed mode HIGH is operated.

If one of the first and second cooling fans 22a and 22b generates an error in both the high speed mode HIGH and the low speed mode LOW, the controller 50 displays the generated error state. The control panel is controlled to allow the normal cooling fan of the first and second cooling fans 22a and 22b to operate in the high speed mode (HIGH operation).

In addition, when an error occurs in both the high speed mode HIGH and the low speed mode LOW in both the first and second cooling fans 22a and 22b, an error condition is displayed on the display unit 18 and the operation is stopped. While operating the alarm generator 60. By operating the alarm generator 60, the user can take follow-up actions.

Next, the controller 50 controls the plurality of heat dissipation fans 24 to be described in general. The process of controlling the heat radiating fan 24 by the controller 50 is almost similar to controlling the first and second cooling fans 22a and 22b described above.

First, when an error occurs in only one of the high speed mode HIGH and the low speed mode LOW in one of the heat radiating fans 24, the controller 50 displays the generated error state on the display unit 18. . Then, the plurality of heat radiating fans 24 are controlled to be switched to another mode which can be partially operated (this is called emergency operation). That is, if the high speed mode HIGH is an error, the operation is performed in the low speed mode LOW, and if the low speed mode LOW is an error, the high speed mode HIGH is operated.

If an error occurs in one of the plurality of heat radiating fans 24 in both the high speed mode HIGH and the low speed mode LOW, the controller 50 displays the generated error state on the display unit 18, Of the heat radiating fan 24 of the normal heat radiating fan 24 is controlled to operate in the high speed mode (HIGH) (this is called emergency operation).

In addition, when all of the plurality of heat dissipation fans 24 have an error in both the high speed mode HIGH and the low speed mode LOW, the generated error state is displayed on the display unit 18, and the alarm generator 60 is stopped while the operation is stopped. ). The operation of the alarm generator 60 allows the user to follow up as well.

Next, the controller 50 controls the first and second cooling fans 22a and 22b and the plurality of heat dissipation fans 24 with reference to FIG. 4A. As shown in FIG. 4A, first, the controller 50 determines whether the plurality of heat radiating fans 24 and the first and second cooling fans 22a and 22b are normally operated (S11). Of course, if it operates normally (S12).

If the plurality of heat dissipation fans 24 and the first and second cooling fans 22a and 22b do not operate normally and only a part of them operate normally (S13), the operation proceeds to emergency operation as described above (S14), Otherwise, if all are abnormal, the operation is stopped (S15). Then, after the control unit 50 has reviewed the normal return (S16), it determines whether or not the normal operation (S17), and if it operates normally (S18), otherwise feeds back to step S13.

FIG. 4B is a control flow diagram illustrating that the controller 50 controls the cooler 21 through the PCB substrate 40 based on the signals of the heat radiating fan 24 and the heat radiating sensor 33. That is, the controller 50 controls the voltage applied from the heat radiating fan 24 and the PCB substrate 40 to the cooler 21 based on the temperature value of the radiator 23 measured by the heat radiating sensor 33. .

As a result, when the temperature of the cooler 21 rises due to an overload or an abnormal state, the controller 50 lowers the voltage applied to the cooler 21 from the PCB board 40 and causes any of the plurality of heat radiating fans 24. One is to switch to the high speed mode (HIGH) to lower the temperature of the cooler (21).

For example, when the temperature of the heat dissipation sensor 33 related to the cooler 21 is 50 ° C. or higher, for example, when the temperature of the cooler 21 exceeds 50 ° C. in a normal operation state, the heat dissipation is performed by the controller 50. The fans 24 are all driven in the high speed mode (HIGH). If the temperature drops below 45 ℃, return to normal operation.

When the temperature of the heat dissipation sensor 33 in relation to the cooler 21 is 55 ° C. or higher, for example, when the temperature of the cooler 21 exceeds 55 ° C., the controller 50 may adjust the maximum voltage applied to the cooler 21. When the temperature of the cooler 21 drops below 50 ° C., the voltage limit is released.

When the temperature of the heat dissipation sensor 33 in relation to the cooler 21 is 60 ° C. or higher, for example, when the temperature of the cooler 21 exceeds 60 ° C., the contact pressure applied to the cooler 21 is turned off. At the time when the temperature of the cooler 21 falls below 50 ° C, the controller 50 returns to normal operation. At this time, if the cooler 21 is overheated three times or more continuously (60 ° C. or more) and generates an error, the controller 50 displays the error state on the display unit 18, and simultaneously operates the alarm generator 60. Stop the operation so that the user can manage it later.

4B, the controller 50 first determines whether the heat dissipation fan 24 operates normally (S21), and detects the heat dissipation temperature when the heat dissipation fan 24 operates normally (S22). Otherwise, the heat dissipation fan 24 is operated in a controlled manner (S23), and then the heat dissipation temperature is detected.

If the predetermined overheat temperature is equal to or higher than the detected heat radiation temperature (S24), the cooler 21 is normally operated (S25) and the temperature of the PCB substrate 40 is detected (S26). If the predetermined overheat temperature is equal to or higher than the detected temperature (S27), the cooler 21 is operated normally (S28), otherwise it is operated by the so-called SMPS control method (S29). Operate (21) to normal.

However, in the step S24, if the predetermined overheat temperature is lower than the detected heat radiation temperature, the voltage from the PCB substrate 40 to the cooler 21 is limited (S30), and the heat radiation temperature is detected (S31). Then, when the predetermined overheat temperature is equal to or higher than the detected temperature (S32), the cooler 21 is controlled normally (S33).

Thus, even if an abnormality occurs in the heat radiating fan 24 that affects the cooler 21, by continuously checking the rotational speed (RPM) of the heat radiating fan 24, the problem caused by the temporary effect is solved immediately to store wine. Can help.

In addition, when overheating of the radiator 23 occurs, the maximum voltage of the cooler 21 is limited, and the heat radiating fan 24 is operated in the high speed mode (HIGH) to maintain the safety of the product so as to contribute to fire prevention. . If the heat dissipation temperature returns to normal, it continuously feeds back and overheats three times or more over a certain temperature to stop the operation to protect the product and the consumer.

FIG. 4C is a control flow diagram showing that the controller 50 controls the first and second storage chamber sensors 31 and 32. As shown in FIG. 4C, the controller 50 determines whether the first and second storage chamber sensors 31 and 32 sense normally (S41). Of course, if it operates normally (S42).

If all of the first and second storage chamber sensors 31 and 32 do not operate normally, and only a part of them operate normally (S43), the operation proceeds to emergency operation as described above (S44). At this time, the emergency operation is the same as that described in Figure 4a.

Otherwise, if all are abnormal to stop the operation (S45). Then, after the control unit 50 performs a normal return review (S46), it determines whether the normal operation (S47), if the normal operation is normal operation (S48), otherwise feeds back to step S43.

Even if the first and second storage room temperature sensor (31,32) is abnormal in this way, while operating on the basis of the heat radiation sensor 33, it is possible to continuously check whether the first and second storage room temperature sensor (31,32) abnormality Therefore, even if an abnormality occurs due to a temporary problem for a certain reason, by operating it can be stored at a constant temperature of the wine.

FIG. 4D is a control flow diagram showing the control unit 50 controlling the heat radiation sensor 33. As shown in FIG. 4D, the controller 50 determines whether the heat radiation sensor 33 is normally sensed (S51). Of course, if it operates normally (S52).

If the heat dissipation sensor 33 does not operate normally, and only a part of the heat dissipation sensor 33 operates normally (S53), the operation proceeds to emergency operation as described above (S54). At this time, the emergency operation is the same as that described in Figure 4a.

Then, it is detected again whether it is normal (S54), and it is determined whether the sensor is normal (S55). If the parser is normal, it operates normally (S56), and if not, feeds back to the step S53. As a result, when an abnormality occurs in the heat radiation sensor 33, it is possible to maintain the wine storage and product safety without problems by operating the product in association with other parts of the surrounding problems.

FIG. 4E is a control flow diagram showing the controller 50 controlling the substrate sensor 35. First, with reference to FIG. 4E schematically, the following embodiments may be implemented.

For example, when the temperature of the substrate sensor 35 provided on the PCB 40 is 65 ° C. or higher, when the temperature of the PCB substrate 40 exceeds 65 ° C. which is a reference value during normal operation, all of the heat dissipation fans 24 are high speed. Drive in HIGH mode. If the temperature drops below 60 ℃, return to normal.

When the temperature of the substrate sensor 35 provided on the PCB substrate 40 is 70 ° C. or more, when the temperature of the PCB substrate 40 exceeds 70 ° C. which is a reference value, the voltage applied to the cooler 21 is limited, and the temperature is again. When the temperature falls below 65 ℃, release the limited voltage.

When the temperature of the substrate sensor 35 provided on the PCB substrate 40 is 80 ° C. or higher, the temperature continues to rise due to an abnormal operation and when the temperature exceeds 80 ° C., the SMPS operation is turned off. Then, it returns to normal operation when the temperature falls below 65 ° C.

If an overheating (greater than 80 ° C.) error of SMPS occurs three or more times in a row, the controller 50 displays an error state on the display unit 18 and simultaneously operates the alarm generator 60 to operate. Control to stop.

This process is described again with reference to FIG. 4E, and the controller 50 determines whether the substrate sensor 35 normally senses (S61). If the substrate sensor 35 is normal, the temperature is detected (S62). Then, if the predetermined overheat temperature is equal to or higher than the detected temperature (S63), the cooler 21 is operated normally (S64).

However, if the predetermined overheating temperature is lower than the detected temperature, the voltage applied to the cooler 21 from the PCB substrate 40 is limited (S65). Then, after detecting the temperature of the PCB substrate 40 (S66), if the predetermined overheat temperature is equal to or higher than the detected temperature (S67), the cooler 21 is operated normally (S68).

If not, a predetermined overheat recovery is detected (S69). If the detected number of times of overheating is three or more times in succession (S70), the operation is stopped (S71). Of course, all of these states are displayed on the display unit 18 by the controller 50 so that the user can easily recognize them.

On the other hand, in step S61, if the substrate sensor 35 is not normal, go to the emergency operation (S72). At this time, the emergency operation is the same as that described in Figure 4a. Then, it detects whether it is normal again (S73), and if the sensor returns to normal (S74), the process proceeds to step S62, and if not, it feeds back to step S72 and continuously enters emergency operation.

For reference, the SMPS function prevents overheating of the power supply. When the SMPS temperature rises above a certain temperature, a limit is applied to the applied voltage to prevent overheating of the power supply. Normal operation by releasing it prevents the risk of fire by protecting the power supply part in case of temporary overheating.

As described above, in the present invention, the control unit 50 controls the corresponding parts separately from the cooling unit 20 and the temperature detecting member 30, so that the corresponding parts are broken, or due to a malfunction or installation environment of the user. All problems can be dealt with appropriately to give reliability for safe driving, and products and stored wine can be kept safe.

Moreover, according to the present invention, when an abnormality occurs in the product, there is an effect that can be immediately informed to the consumer. In addition, when an abnormality occurs in the product, it does not stop the operation unconditionally, but continuously checks whether there is an abnormality and provides the effect of operating normally again when a specific abnormality is removed.

As described above, according to the present invention, it is possible to give reliability to safe operation by appropriately dealing with all the problems caused by the failure of the corresponding parts or the malfunction of the user and the installation environment. Wine refrigerators are provided for safe keeping and storage of wine.
