Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a refrigerator provided with a deodorizing device that decomposes a malodorous component in the refrigerator.

[0002]

[Prior art]

 Ozone is a colorless and special odor gas that has a strong oxidizing power and has a strong effect on sterilization and deodorization. In recent years, in order to utilize the characteristics of ozone to deodorize the inside of the refrigerator, refrigerators equipped with a deodorizing device with a built-in ozone generator have been supplied.

A conventional refrigerator provided with this deodorizing device will be described with reference to FIG. A cold air passage 5 is formed on the rear side of the box-shaped refrigerator main body 1 on the inside 3 side by forming a gap between the refrigerator main body 1 and the main body 1. The cold air passage 5 has an upper end portion and a lower end portion inside the refrigerator 3 It is open to. A cooler 7 for exchanging heat is provided in the cool air duct 5, and a defrosting heater 11 for defrosting the frost adhering to the cooler 7 is attached below the cooler 7. There is. The cooler 7 is cooled by being supplied with a refrigerant from a machine room 9 provided in the upper portion of the main body 1. A blower fan 13, which is a cool air circulation fan, is provided in the upper part of the cool air duct 5, and the blower fan 13 blows the air in the cool air duct 5 to the inside 3 of the refrigerator. That is, the air in the cool air passage 5 is blown to the inside 3 of the refrigerator by the blower fan 13 after passing through the cooler 7, and the air blown into the inside 3 is again sucked from the lower end of the cool air passage 5. It is supposed to be.

On the other hand, between the cooler 7 and the blower fan 13 in the cool air duct 5, a deodorizing device 15 having a catalyst and an ozone generator (not shown) is installed, and passes through the cooler 7. The chilled air passes through the deodorizing device 15.

In the refrigerator thus configured, when the blower fan 13 is driven and the refrigerant is supplied from the machine room 9 to the cooler 7, the refrigerant is evaporated in the cooler 7 and absorbs heat of vaporization. Cooler 7 is cooled. The air passing through the cooler 7 by the blower fan 13 is heat-exchanged by the cooler 7 having a low temperature to become cool air. The cool air that has passed through the cooler 7 passes through the deodorizing device 15 and reacts with the ozone generated by the ozone generator to decompose the odor, and the excess ozone is decomposed by the catalyst to eliminate the special odor. The odorless cool air is blown from the blower fan 13 to the inside 3 of the warehouse, and after removing latent heat from the stored items inside the warehouse 3 to reach a high temperature, it is taken in together with the odor of the inside 3 from the lower end of the cool air duct 5. , And is cooled again by the cooler 7.

By the way, in the refrigerator, when the outside air flows into the interior 3 as the door is opened and closed, a phenomenon occurs in which the water contained in the outside air frosts on the cooler 7. Since this frost significantly reduces the heat exchange between the cooler 7 and the passing air, it needs to be removed. Therefore, in the refrigerator, after the cooling operation for a certain period of time, electricity is periodically supplied to the defrosting heater 11 to heat the defrosting heater 11 to raise the temperature of the cooler 7 and thaw the adhered frost. Defrosting is performed. During defrosting, the temperature of the cooler 7 rises and part of the defrosted frost evaporates, so the humidity of the air passing through the cooler 7 rises.

[0007]

[Problems to be solved by the device]

 In the conventional refrigerator provided with the deodorizing device 15, ozone is applied to the cool air passing through the cooler 7 to decompose the odor. However, in the refrigerator, defrosting is performed in order to remove the frost, and during this defrosting, the air passing through the cooler 7 becomes hot and humid. Then, the deodorizing device 15 that has been cooled by the cool air until immediately before defrosting causes dew condensation when the hot and humid air that has passed through the cooler 7 hits it. As a result, immediately after defrosting, the deodorizing ability of the deodorizing device 15 may be extremely lowered (since the discharge type ozone generating device using the ozone generating tube cannot secure a predetermined discharge state, In particular, the decline in capacity is significant).

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a refrigerator in which dew condensation does not occur in a deodorizing device, and to prevent deterioration of deodorizing ability.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the refrigerator according to the present invention has an air-cooled condenser provided outside the main body, a cold air circulation fan for sending cool air into the refrigerator provided in the cool air duct, and an ozone generator. In a refrigerator to which a built-in deodorizing device is attached, the deodorizing device is disposed adjacent to the leeward side of the air-cooled condenser, and the other end of the intake pipe whose one end is open to the inside of the refrigerator is the deodorizing device. The exhaust pipe is connected to the intake port and one end of the exhaust pipe is opened to the cold air passage on the negative pressure side of the cold air circulation fan, and the other end is connected to the exhaust port of the deodorizing device.

[0010]

[Action]

 The hot air from the air-cooled condenser hits the deodorizing device and warms the deodorizing device. By driving the cool air circulation fan, the air in the refrigerator enters the deodorizing device through the intake pipe, and even if the air in the refrigerator flows in the warmed deodorizing device, dew condensation does not occur. The air in the refrigerator that entered the deodorizing device is decomposed into a bad odor, exhausted through the exhaust pipe into the cool air duct, and then blown again into the refrigerator via the cool air circulation fan.

【Example】

 Hereinafter, a preferred embodiment of a refrigerator according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view showing a refrigerator according to the present invention, and FIG. 2 is a plan view showing an upper surface portion of the refrigerator according to the present invention. The same members as those shown in FIG. 3 are designated by the same reference numerals, and a duplicate description will be omitted.

As shown in FIG. 1, a machine room 23 is provided on the top surface of the top plate 21 of the refrigerator body 1, and a deodorizing device in which a catalyst and an ozone generator are incorporated on the top plate 21 in the machine room 23. 25 is attached. The deodorizing device 25 is provided with an intake port 27 that serves as an intake of odor and an exhaust port 29 that exhausts the deodorized air that has become odorless. The intake port 27 is connected to the other end of an intake pipe 31 having one end opening to the inside 3, and the exhaust port 29 has one end to cool air on the negative pressure side (cooler 7 side) of the blower fan 13 which is a cool air circulation fan. An exhaust pipe 33 opening to the passage 5 is connected. The intake pipe 31 and the exhaust pipe 33 communicate with each other via a deodorizing device 25. That is, the inside 3 and the inside of the cool air duct 5 are communicated with each other through the intake pipe 31, the deodorizing device 25, and the exhaust pipe 33. When the blower fan 13 is driven, the inside of the cool air passage 5 on the front side has a high pressure across the blower fan 13 and the inside of the cool air passage 5 on the rear side has a low pressure (negative pressure). Therefore, when the blower fan 13 is driven, the air in the cold storage 3 is sucked in through the intake pipe 31, passes through the deodorizing device 25, and then passes through the exhaust pipe 33 to become a negative pressure. 13 is sucked backwards. Then, the air sucked to the rear of the blower fan 13 is returned to the interior 3 again via the blower fan 13.

On the other hand, as shown in FIG. 2, the deodorizing device 25 is disposed on one end side of the top plate 21 in the left-right direction of the refrigerator, and the top plate 21 on the other end side of the deodorizing device 25 compresses the refrigerant. 35 are provided adjacent to each other. Further, a condenser cooling fan 37 and a condenser 39 are attached adjacent to the top plate 21 on the other end side of the compressor 35. That is, the deodorizing device 25, the compressor 35, the condenser cooling fan 37, and the condenser 39 are arranged in a straight line. By the way, the condenser 39 discharges the heat taken from the inside 3 and the compressor 35 generates the heat associated with the compression work of the refrigerant. Therefore, when the condenser cooling fan 37 is driven, the air sucked from the other end of the condenser 39 removes exhaust heat from the condenser 39 and is then blown to the compressor 35 side. After depriving the user of heat and becoming high in temperature, it hits the deodorizing device 25. In other words, the deodorizing device 25 is arranged under the hot air generated by the exhaust heat of the condenser 37 and the compressor 35 so that it can be always warmed.

In the refrigerator thus configured, when the blower fan 13 is driven and the compressor 35 is driven, the blower fan 13 blows the cool air that has passed through the cooler 7 to the inside 3 of the refrigerator, The air in the storage 3 is passed through the intake pipe 31 to the deodorizing device 25 to decompose the malodorous components, sucked into the cool air duct 5, and circulated in the storage 3 again. When the refrigerator is defrosted, the defrosting heater 11 thaws the frost on the cooler 7, and the air that has passed through the cooler 7 does not pass through the deodorizing device 25. Is blown to. At this time, the humid air having a relatively high temperature passing through the defrosting device passes through the deodorizing device 25, but since the deodorizing device 25 is warmed by the exhaust heat from the condenser 39 or the like, the dew point temperature is reached. No condensation occurs.

[0015]

[Effect of device]

 As described above in detail, according to the refrigerator of the present invention, the deodorizing device is arranged on the lee side of the air-cooled condenser outside the refrigerating machine body and is always warmed by the exhaust heat from the air-cooled condenser. Therefore, dew condensation does not occur and it is possible to prevent the deodorizing ability from decreasing. Further, in the present invention, the cool air immediately after passing through the cooler does not pass through the deodorizing device as in the conventional case, but the air once blown into the refrigerator is directly passed through the deodorizing device. Along with the high temperature of the device, the intake air temperature rises and the ozone generation efficiency increases, so the deodorizing ability can be improved.
