A deodorizing device 22 is provided in the bypass flow passage 21. When all the dampers provided in the air passage are closed, the cool air is not supplied to the air passage having almost no air resistance, and the air resistance is reduced. Since most of the cold air is supplied to the large bypass channel 21, a short cycle occurs, and all the cold air in the closed space including the cooling chamber closed by the damper is forced to pass through the deodorizing device 22 by the refrigerator compartment fan 14. As a result, a deodorizing effect can be obtained, and no unpleasant odor will be supplied to each chamber even if the damper is opened.

Further, when at least one damper of 15a, 15b, 15c, and 15e is open, the cold air is supplied to the air flow path having almost no air resistance. Almost no short cycle is generated and the deodorizing effect by the deodorizing device 22 is hardly obtained. However, since there is no air path resistance during the cooling operation, there is no shortage of cooling capacity.

The cooling chamber 120 includes a cooler 121 that is a cross fin coil, and a heat insulating member 122 is disposed between the front surface of the cooler 121, the back cover 104, and the deodorizing device 150. The cooler 121 cools the air from the refrigerator compartment 102 in which the refrigerant flows in the pipe and the air flows outside the pipe and flows in from the lower part.

  The refrigerating room fan 130 that is an axial flow type is disposed above the cooling room 120 and is attached so as to suck in air from the cooling room 120 and blow it to the air passage 140.

  The air supply path 140 is a blowout air path used to open the plurality of air outlets 141 and blow cold air into the refrigerator compartment 102.

  The deodorizing device 150 is attached to the back cover 104 and is disposed in a space independent from the air passages 110 and 140.

  4 and 5, the deodorizing apparatus 150 includes a base member 151 installed in the back direction of the refrigerator compartment 102, a cover 152 exposed to the refrigerator compartment 102, a deodorizing fan 153, and adsorption deodorizing filters 154 a and 154 b. And an ultraviolet lamp 155.

  For the base member 151, it is preferable to use polypropylene that is moldable as a material and durable to ozone generated by the ultraviolet lamp 155, and an air outlet 151a is formed in the vicinity of the upper part in the installed state.

  The cover 152 is preferably made of ABS or glass, which has excellent moldability as a material, is durable against ozone generated by the ultraviolet lamp 155, and is transparent. 152a and 152b are formed, and a suction port 152c is formed near the lower part in the installed state.

  The deodorizing fan 153 is an axial flow fan, and is set so that the air blowing capacity is smaller than that of the refrigerator compartment fan 130. Here, the deodorizing fan 153 is installed so as to blow out air in the direction of the openings 152 a and 153 a, and is attached to the deodorizing device 150 so as to be inclined. Here, the deodorizing fan 153 is controlled to be in an operating state at least when the refrigerator door is opened.

  The adsorption deodorizing filters 154a and 154b are disposed upstream of the deodorizing fan 153 with respect to the circulation of cold air. The material is a filter in which a honeycomb-shaped ceramic substrate carries a physical adsorbent such as activated carbon or zeolite, or a catalyst material of a chemical adsorbent composed of a composite inorganic oxide such as manganese oxide or copper oxide, and a fan for deodorization. Are substantially parallel and arranged in parallel. As the filter base material, a ceramic base material made of silica or alumina is preferable when an inorganic oxide chemical adsorbent that is baked in the production process is used.

  In addition, an organic substance composed of an enzyme or the like may be used as a catalyst material other than a physical adsorbent or a chemical adsorbent. In this case, a plastic base material such as a nonwoven fabric, synthetic paper, or polypropylene may be used as a filter base material. it can.

  Here, the deodorizing fan 153 and the adsorption deodorizing filters 154a and 154b are attached to the base member 151 by a fixing member 156. The fixing member 156 includes the periphery of the cross section of the deodorizing fan 153 and the adsorption deodorizing filters 154a and 154b. It has a shape that seals the periphery of the cross section. As a material of the fixing member 156, it is preferable to use polypropylene which is durable to ozone generated by the ultraviolet lamp 155 in view of moldability.

  The ultraviolet lamp 155 is disposed upstream of the adsorption deodorizing filters 154a and 154b with respect to the flow of cold air. The lamp tube of the ultraviolet lamp 155 is made of high-purity quartz glass, and a low-pressure mercury vapor and an inert gas such as argon or xenon are enclosed in the lamp tube. The lamp tube does not have electrodes, and a high frequency high voltage is applied to both ends outside the lamp tube through an inverter circuit (not shown).

  Here, when the ultraviolet lamp 155 is turned on, since the lamp tube of the ultraviolet lamp 155 is made of high purity quartz glass, the low wavelength ultraviolet rays generated by the discharge under mercury vapor in the lamp tube are not shielded. There is an action of transmitting through the tube wall, ultraviolet light having a wavelength of 185 nm and ultraviolet light having a wavelength of 254 nm are irradiated to the outside of the lamp tube, and oxygen molecules in the air are converted into an oxygen radical state by the energy of the ultraviolet light having a wavelength of 185 nm. Radicals and oxygen react to produce ozone.

  Here, the ultraviolet lamp 155 is controlled to light up when the door of the refrigerator is opened.

  The deodorizing air passage 160 is an air passage formed in the heat insulating member 122, one end is connected to the air outlet 151 a formed near the upper portion of the base member 151, and the other end is a chamber below the cooling chamber 120. 112.

  About the refrigerator provided with the deodorizing apparatus comprised as mentioned above, the operation | movement is demonstrated below.

  First, in the case of a deodorizing operation while the refrigerator compartment fan 130 is operating, in an actual refrigerator, the cooling operation or the initial stage of the defrosting operation corresponds to this, and the air in the refrigerator compartment 102 flows into the air passage 110 from the plurality of suction ports 111. And gather in the chamber 112 below the cooling chamber 120. The collected air is cooled when passing through the cooler 121, blown to the air blowing path 140 by the cold room fan 30, and blown into the cold room 102 from the plurality of outlets 141.

  Here, in the deodorizing device 150 arranged in a space independent from the air passages 110 and 140, the air in the refrigerator compartment 102 is sucked into the deodorizing device 150 from the suction port 152c formed near the lower portion of the cover 152. It is. The odor component contained in the sucked air is deodorized and sterilized by the effect of ozone generated by the ultraviolet lamp 155 and the effect of short wavelength ultraviolet rays.

  However, not all of the odorous components that have passed through the vicinity of the ultraviolet lamp 155 are decomposed and are adsorbed by the adsorption deodorizing filters 154a and 154b installed downstream of the ultraviolet lamp 155. Further, ozone generated by the ultraviolet lamp 155 flows downstream together with air, and decomposes odor components adsorbed by the adsorption / deodorization filters 154a and 154b.

  The air containing a small amount of ozone passes through the adsorption deodorizing filters 154a and 154b, is pressurized by the deodorizing fan 153, and is directly blown out from the outlets 152a and 152a to the refrigerating chamber 102. Decomposes and floating bacteria.

  At this time, since the refrigerator compartment fan 130 is in operation, the vicinity of the chamber 112 has a negative pressure, and the air containing a small amount of ozone pressurized by the deodorizing fan 153 is deodorized connected to the air outlet 151a. It passes through the sealed path 60, is sent to the chamber 112, and is blown out to the cooling room 102 via the cooler 121, the refrigerator compartment fan 130, and the air blowing path 140.

  That is, the refrigerator compartment fan 130 and the deodorizing fan 153 are connected in series to form an air passage including the deodorizing sealed passage 160, and odor components and airborne bacteria in the air passage are decomposed.

  On the other hand, in the case of a deodorizing operation in which the refrigerator fan 130 is not operating, in an actual refrigerator, this is the time when the thermo is off, after the middle of the defrosting operation, and when the door is open, and is arranged in a space independent from the air passages 110 and 40. In the deodorizing device 150, the air in the refrigerator compartment 102 is sucked into the deodorizing device 150 from the suction port 52c formed near the lower portion of the cover 152.

  The odor component contained in the sucked air is deodorized and sterilized by the effect of ozone generated by the ultraviolet lamp 155 and the effect of short wavelength ultraviolet rays. However, not all of the odorous components that have passed near the ultraviolet lamp 155 are deodorized, but are adsorbed by the adsorption deodorizing filters 154a and 154b installed downstream of the ultraviolet lamp 155.

  Further, ozone generated by the ultraviolet lamp 155 flows downstream together with air, and decomposes odor components adsorbed by the adsorption / deodorization filters 154a and 154b. The air containing a small amount of ozone passes through the adsorption deodorizing filters 154a and 154b, is pressurized by the deodorizing fan 153, and is directly blown out from the outlets 152a and 152a to the refrigerating chamber 102. Decomposes and floating bacteria.

  At this time, since the refrigerator compartment fan 130 is stopped, the deodorizing air passage 160 is connected to the refrigerator compartment 102 via the cooler 121, the refrigerator compartment fan 130, the air passage 140, and the outlet 141. The total air passage resistance obtained by adding the air passage resistance in the deodorizing device 150 to this air passage resistance must be covered only by the deodorizing fan 130, and the passing air amount becomes substantially zero.

  Similarly, the amount of air passing through the deodorizing air passage 160 from the deodorizing air passage 160 through the air blowing passage 110 and the suction port 11 to the refrigerator compartment 102 is substantially zero. Therefore, the amount of air blown directly from the outlets 152a, 152a to the refrigerator compartment 102 is balanced with a larger amount of air as compared with the state in which the refrigerator compartment fan 130 is operating, and a predetermined deodorizing performance is maintained.

  When deodorization is stopped while the refrigerator compartment fan 130 is in operation, in an actual refrigerator, the cooling operation or the initial stage of the defrosting operation corresponds to this, and the air in the refrigerator compartment 102 passes through the air passage 110 from the plurality of suction ports 111. Then, they gather in the chamber 112 below the cooling chamber 120. The collected air is cooled as it passes through the cooler 121, and is blown into the air passage 140 by the cold room fan 130 and blown into the cold room 102 from the plurality of outlets 141.

  At this time, the air in the refrigerator compartment 102 is sucked into the blower passage 110 from the outlets 152a and 152a via the deodorizing air passage 160.

The deodorizing air passage 160 is connected to the deodorizing device 150 and the blowout ports 152a and 152b for directly blowing the deodorized air to the refrigerating chamber 102 are formed. In a state where 30 is operating, and at the same time blowing air after deodorization in the cooling air passage 110 and 140, it is possible to blow air after direct deodorization to the refrigerating compartment 102.

  In addition, since the deodorizing air passage 160 is connected to the air blowing passage 110 that is the suction air passage, the refrigerating room fan 30 and the deodorizing fan 153 are arranged in series when the refrigerating room fan 30 is operating. Therefore, the air volume passing through the deodorizing air passage can be increased.

  Further, since the blowing capacity of the deodorizing fan 153 is smaller than the blowing capacity of the refrigerator compartment fan 30, when the refrigerator compartment fan 30 is stopped, the amount of air passing through the ventilation path 110 and the ventilation path 140 is substantially 0. Can be.

  Further, the amount of air blown directly from the outlets 52a and 52b to the refrigerator compartment 102 can be increased as compared with the state where the refrigerator compartment fan 30 is operating.

  In addition, a refrigerator compartment 102 that is disposed in front of the refrigerator 1 main body and stores food and the like, and a cooler 121 that is provided in a cooling chamber 120 disposed behind the refrigerator 1 and generates cold air for cooling the refrigerator compartment 102; A cooling passage 102 that is a flow path of cool air to the refrigerating chamber 102, a refrigerating chamber fan 53 that is provided in the blowing passage 110 and blows the cool air generated by the cooler 20 into the refrigerating chamber 102, The deodorizing device 150 provided outside the passages 110, 40 and forming the outlets 52 a, 52 b for directly blowing the deodorized air to the refrigerator compartment 102, and having the ultraviolet lamp 155, and the deodorizing device 150 are provided.

Since located, it is possible to deodorize the cooler by the effect of ozone generated in the UV lamp 155.

  Further, the ultraviolet lamp 155 is controlled so as to be lit when the refrigerator door is opened, and the cover 152 exposed to the refrigerator compartment 102 is made of a transparent material. Can also be used as

  In addition, due to the effect of ozone generated by turning on the ultraviolet lamp 155 and ultraviolet rays having a short wavelength, a sterilizing effect on floating bacteria existing in the refrigerator compartment 102, the air ducts 110 and 140 and the cooler 121 and bacteria attached to the wall surface is expected. it can.
