[0018]
Note that 25 is a cooler, 26 is a blower assembly having a fan 27, and 28 is a pressure chamber that leads to the cold air distribution chamber 15. Reference numeral 29 denotes an electrical box assembly that houses an electrical circuit assembly 29a for operating the refrigerator and has an external lid.
[0019]
The cool air cooled by the cooler 25 is sent to the pressure chamber 28 by the fan 27 of the blower 26. Thereafter, cold air is sent from the pressure chamber 28 to the freezing chamber (not shown). Further, a temperature sensing unit (not shown) provided in the refrigerator compartment 2 senses the room temperature of the refrigerator compartment 2, and when the room temperature becomes higher than a predetermined temperature, a damper (not shown) of the cold air distributing chamber 15 is provided. The cold air that opens and enters the cold air distribution chamber 15 from the pressure chamber 28 is sent to the cold room cold air distribution passage 16a.
[0020]
Thereafter, the cool air rises upward in the refrigerating room cool air distribution passage 16a, and a part of the cool air flows from the upper center of the refrigerating room cold air distribution passage 16a into the ceiling-side cold air passage 17. The cold air flowing into the ceiling-side cold air passage 17 passes through the ceiling-side cold air passage 17 and is sent forward while spreading in the left-right direction. From the ceiling-side cold air outlet 17a and the left and right cold-air outlets 17b, the refrigerator compartment on the ceiling side. The cooling efficiency of the refrigerating chamber 2 is increased by being discharged evenly over the entire area 2.
[0021]
Then, the cool air changes its direction downward from the upper end of the refrigerating room cool air distribution passage 16a, and is discharged from the plurality of refrigerating room cold air discharge ports 14 to the refrigerating chamber 2 while passing through the refrigerating room cold air distribution passage 16a. The remaining cold air passing through the cold room cold air distribution passage 16 a is sent from the case cold air outlet 13 to the case 7 in the isolation chamber 4.
[0022]
The cool air sent into the case 7 cools the stored items in the case 7 and flows out from the gap between the front upper end of the case 7 and the case shelf 8 to the refrigerator compartment 2. Thereafter, the cold air flowing out from the gap is mixed with the relatively warm cold air descending from the upper side of the refrigerator compartment 2 and passes through the deodorizing assembly 11 which is a deodorizing means provided near the front of the isolation chamber 4. The odor generated from the stored items in the isolation chamber 4 and the refrigerator compartment 2 is deodorized and guided to the refrigerator compartment cold air return port 10. And the cold air which passed through the refrigerator compartment cold air return port 10 is sent out to the vegetable chamber 3 from the vegetable chamber cold air discharge port 12.
[0023]
Note that the amount of cold air sent from the case cold air outlet 13 to the case 7 is adjusted by the opening area of each outlet so that the temperature in the case 7 is maintained at a lower temperature than the refrigerator compartment 2. .
[0024]
Further, since the deodorizing assembly 11 and the refrigerator compartment cold air return port 10 are located in the lower front of the refrigerator compartment 2, the cold air discharged from the case cold air outlet 13 and the refrigerator air cooler outlet 14 is directly stored in the refrigerator compartment cold air return port 10. Circulates in the isolation chamber 4 and the refrigerator compartment 2 to cool the stored items, and returns the cold air from the wide area of the deodorizing assembly 11 provided near the lower front of the refrigerator compartment 2. The air can be sucked into the cold air return port 10, and a more uniform cold air flow in the refrigerator compartment 2 can be obtained, and a refrigerator with improved cooling efficiency can be obtained.
[0025]
Further, since the return cold air after circulating through the isolation chamber 4 and the refrigerator compartment 2 and cooling the stored material passes through the deodorizing assembly 11, it is emitted from the stored materials in the isolation chamber 4 and the refrigerator compartment 2. The odor is deodorized by the deodorizing assembly 11. Therefore, it is possible to quickly deodorize the odors of stored products that are likely to emit strong odors such as fish entering the isolation chamber 4, and generate a large amount of odors emitted from the stored items in the refrigerator compartment 2 having a relatively high storage temperature. A refrigerator can be obtained that can efficiently and directly deodorize near the source, and the odor of the isolation chamber 4 or the refrigerator compartment 2 is difficult to transfer to others.
[0026]
Moreover, since the deodorizing assembly 11 is located in a wide space near the front of the isolation chamber 4, the deodorizing assembly 11 can be taken in a relatively wide area, the amount of deodorizing is increased, and the deodorizing efficiency is further improved. Furthermore, since the deodorizing cover 11a and the deodorizing assembly 11 are near the front of the isolation chamber 4 and near the lower front of the refrigerator compartment 2, the deodorizing cover 11a is formed of a transparent resin, or the deodorizing assembly 11 is formed from a part thereof. If it is made visible, the deodorizing assembly 11 is easy to see and can be seen every time the refrigerator compartment door 18 is opened. Moreover, since it is in front of the refrigerator compartment 2, the deodorizing assembly 11 is maintained. In particular, if the deodorizing cover 11a and the deodorizing assembly 11 are detachable, the refrigerator can be easily taken out from the refrigerator compartment 2 and the deodorizing cover 11a and the deodorizing assembly 11 can be easily maintained.
[0027]
A part of the cold air flowing into the vegetable compartment 3 through the vegetable compartment cold air outlet 12 flows forward through the cold passage formed by the partition portion 5 and the vegetable compartment cover 24, and the remaining cold air is separated from the partition portion 5 and the vegetable compartment. The cool air passage formed by the cover 24 flows backward. The cold air that has flowed forward passes through the front cold air passage 24 a provided at a position away from the opening above the vegetable case 22 and the accessory case 23, and the vegetable case 22 and the rear door of the vegetable compartment door 21. After passing through, it reaches the outside of the bottom of the vegetable case 22. Thereafter, the cold air passes through the outside of the bottom surface of the vegetable case 22 and returns from the vegetable compartment 3 to the lower side of the cooler 25 by a duct (not shown).
[0028]
Moreover, the said cold air | flow which flowed back passes the back cool air passage part 22b provided in the position which avoided the opening part above the vegetable case 22 and the accessory case 23, and the vegetable case 22 and the back wall of the vegetable compartment 3 After passing through, it returns to the downward direction of the cooler 25 with a duct (not shown).
[0029]
Therefore, the cold air that has flowed into the vegetable room 3 through the vegetable room cold air discharge port 10 starts to flow over the whole area of the vegetable room cover 24, and the efficiency of the cold airflow above, in front, below, and behind the vegetable case 22 The refrigerator has a vegetable compartment 3 that can be cooled indirectly. Further, the cold airflow in the vicinity of the isolation room 4 at the upper part of the vegetable room cover 24 reduces local cooling to the vegetable room 3 by the isolation room 4 when the isolation room 4 is at a lower temperature than the refrigerating room 2. In addition, the arrow in a figure represents the flow of cold air.
[0030]
The cold air flowing into the vegetable compartment 3 is the return cold air from the refrigerator compartment 2, but since the odor has been deodorized by the deodorizing assembly 11, the stored matter in the vegetable compartment 3 has no unpleasant odor. .
[0031]
And since the refrigerator compartment 2 and the vegetable compartment 3 with which there is not much difference in indoor temperature are provided adjacent to the upper and lower sides, the thickness of the heat insulation layer of the partition part 5 may be thin, and effective use of indoor volume The partition 5 has a concave shape on the top.
[0032]
In addition, since the cold air that has passed through the deodorizing assembly 11 immediately flows into the vegetable compartment 3 that is a storage room under the refrigerator compartment 2, the cold air passage to the vegetable compartment 3 is short, and the deodorizing assembly 11 and the vicinity of the cold air passage Thus, a refrigerator with improved deodorization efficiency can be obtained, in which the resistance to ventilation by the cold air passage is reduced.
[0033]
And the passage of the cold air distribution chamber 15 is not so large in the left-right direction due to the size of the damper, and has a large width in the front-rear direction to ensure a ventilation area. For this reason, the refrigeration room cold air distribution passage 16a immediately after exiting the cold air distribution chamber 15 also needs to have the same width in the front-rear direction so as not to lower the ventilation efficiency, and the front surface of the refrigeration room cold air distribution passage 16a protrudes forward. It will be located in the place.
[0034]
Further, the case cold air outlet 13 is located in the cold room cold air distribution passage 16a located away from the cold air distribution chamber 15, and the cold room cold air distribution passage 16a in the vicinity thereof has a large width in the left-right direction and a width in the front-rear direction. The case cool air outlet 13 can be located rearward, and the inclination from the vicinity of the cold air distribution chamber 15 to the vicinity of the case cold air outlet 13 of the refrigerator compartment cold air distribution passage 16a is inclined so as to recede toward the rear. ing. Therefore, the volumetric efficiency of many parts of the refrigerator compartment 2 is good.
[0035]
Further, in this figure, only the ceiling side cold air passage 17 connected to the upper center of the cold room cold air distribution passage 16a of the cold room passage assembly 16 is provided, but it extends from the cold room cold air distribution passage 16a to the left and right, and the front of the cold room 2 If the front cool air passage extending to the front is provided at an appropriate position (for example, the center between the shelves 8a, 8b and 8c of the refrigerating chamber 2), and the cool air discharge port is provided in the front cool air passage, the inside of the refrigerating chamber 2 It is clear that the cooling efficiency is improved by sending the cold air uniformly to the stored product.
[0036]
In this figure, the rotation center of the fan 27 provided in the blower 26 is cut, the case cold air outlet 13 and the refrigerator air cooler outlet 14 are cut, and then the vicinity of the center of the ceiling side cold air passage 17 is cut. Is.
[0037]
In FIG. 2, the cold air sent from the cold air distribution chamber 15 to the lower side of the cold room cold air distribution passage 16a (indicated by a dotted line) is divided into two left and right passages by the pressure generated by the fan 27 of the blower 26. The inside of the passage 16a is pushed upward. Thereafter, a part of the cold air pushed up to the upper end of the refrigerator compartment 2 through the left and right passages flows from the upper center of the refrigerator compartment cold air distribution passage 16a into the ceiling cold passage 17 and passes through the ceiling cold air passage 17 to the left and right. It is sent forward while spreading in the direction, and is uniformly discharged from the ceiling side cold air outlet 17a and the left and right side cold air outlet 17b to the entire upper part of the refrigerator compartment 2 on the ceiling side, thereby further improving the cooling efficiency of the refrigerator compartment 2. become.
[0038]
Further, the remaining cold air is led to a passage that reverses to the left and right, passes through the inside of the cold room cold air distribution passage 16a, falls below the cold room 2, and descends to the case cold air outlet 13 at the end of the cold room cold air distribution passage 16a. During this time, the cold air is sent out from the respective cold room cold air outlets 14 to the cold room 2, and the remaining cold air is sent out from the case cold air outlet 13 to the case 7.
[0039]
In addition, the arrow in a figure represents the cold air flow in the refrigerator compartment cold air distribution channel | path 16a. Further, in order to make the flow of cool air easy to understand, the case 7, the partition 5, the case shelf 8, and the shelves 8 a, 8 b, and 8 c in the isolation chamber 4 are removed.
[0040]
The opening corresponding to the cold room outlet 14 of the passage cover 16c is formed in a slit shape so that stored items or the like do not enter inside. Further, the passage cover 16c is provided with a temperature sensing unit 30 for sensing the room temperature in the refrigerating chamber 2, and ribs are provided so that the cold air from the refrigerating chamber cold air outlet 14 above does not directly hit the temperature sensing unit 30. A shaped eaves 31 is provided. A lamp cover 32 is provided with a lamp (not shown) for illuminating the inside of the refrigerator compartment 2 on the back side.
[0041]
In FIG. 3, a deodorizing assembly 11 is placed on the upper surface of the refrigeration chamber cold air return port 10 near the front of the isolation chamber 4 near the lower front of the refrigeration chamber 2, for example, a sponge-like seal made of an independent foam. The deodorizing cover 11a is provided so as to cover the deodorizing assembly 11 further above the deodorizing assembly 11, and is removably attached around the refrigerator compartment cold air return port 10 via a member). It is attached with nails.
[0042]
Therefore, even if a liquid such as soy sauce is accidentally spilled above the deodorizing assembly 11, the deodorizing cover 11 is not applied because of the deodorizing cover 11 a, and further, it protects falling objects from above a bottle or the like. It is also.
[0043]
In addition, a deodorizing cover 11a is provided in a space between the outer side of the bottom surface of the case 7 and the deodorizing cover 11a so as not to touch the outer side of the bottom surface of the case 7 when the case 7 is pulled out from the isolation chamber 4. .
[0044]
A protrusion having an inclined surface 7b that rises upward toward the rear is provided on the front outside the bottom surface of the case 7. Further, a case bottom seal 5b (for example, a sponge-like seal made of an independent foam) is attached to the top surface of the protruding portion 5a of the partition portion 5 facing the inclined surface 7b. The inclined surface 7b and the case bottom seal 5b come into contact with each other when the case 7 is completely stored in the isolation chamber 4, or the case bottom seal 5b comes into contact with the inclined surface 7b and the case bottom seal 5b. 7 has a blocking structure that blocks the cold airflow in the space between the protrusion 7 and the protrusion 5a. Reference numeral 5c denotes a positioning rib for positioning when the case bottom seal 5b is attached to the top surface of the protrusion 5a.
[0045]
And since the protrusion with the inclined surface 7b is in front of the bottom surface of the case 7 and the case 7 is stored in the isolation chamber 4, the protrusion approaches the top surface of the protrusion 5a for the first time immediately before the storage is completed. The projection is unlikely to get caught in other places, and there is no possibility of hindering the storing operation. Further, since the inclined surface 7b that rises upward as it goes rearward is provided outside the bottom surface of the case 7, it is possible to press the case 7 against the sealing surface of the case bottom seal 5b simply by pressing the case 7 horizontally into the isolation chamber 4. Improve. The case bottom seal 5b is made of a soft material having a repulsive force that can be completely pressed down by its own weight.
[0046]
Further, the projection 7c in front of the case guide 7a and the side wall projection 9c of the projection in front of the side wall guide jitter 9b are provided with a hook so that the case 7 does not shift forward, and the sealing performance is maintained. When the case 7 is pulled forward, the case handle 7d is pulled upward slightly after removing the hooks 7c and the side wall protrusions 9c upward.
[0047]
In addition, since the deodorizing cover 11a and the deodorizing assembly 11 can be removed from the refrigerating room cool air return port 10 after the case 7 is taken out from the isolation chamber 4, the partition part 5, the refrigerating chamber cold air return port 10, the deodorizing assembly 11 and the deodorizing unit can be removed. The cover 11a can be cleaned and replaced, and can be kept clean.
[0048]
In addition, when the depth of the said deodorizing cover 11a and the deodorizing assembly 11 is short, it does not overlap so much on the outer side of the bottom face of the case 7, and is in front of the isolation chamber 4, the deodorizing capability of the deodorizing assembly 11 is a little. Although falling, it is obvious that the same effect as described above can be obtained without removing the case 7 from the isolation chamber 4.
[0049]
Next, the flow of the cold air will be described. The cold air discharged from the case cold air outlet 13 is sent into the case 7. Then, the cool air cools the stored item in the case 7 and flows out from the gap between the front upper end and the case shelf 8 to the refrigerator compartment 2. The cold air flowing out from the gap mixes with the relatively warm air coming down from the top of the refrigerator compartment 2, passes through the opening of the deodorizing cover 11a, passes from the upper surface to the lower surface of the deodorizing assembly 11, and spreads to the bottom. It is sent out to the vegetable compartment 3 from the room cold air outlet 12.
[0050]
And the deodorization assembly 11 is provided in the opening part of the refrigerator return air | gas return port 10 with the width | variety which spreads right and left near the width | variety of the case 7, From the whole upper surface side of the wide deodorization assembly 11 which spreads back and forth right and left The deodorizing assembly 11 passes uniformly, and the return cold air in the refrigerator compartment 2 flows into the vegetable compartment 3 from the lower surface side of the deodorizing assembly 11.
[0051]
Therefore, the cold air flow in the refrigerating room 2 becomes more uniform, the whole stored item in the refrigerating room 2 is uniformly and efficiently cooled, and the deodorizing assembly 11 having a wide width that spreads the returned cold air in the front, rear, left and right is efficiently deodorized. And since it passes the whole upper and lower surfaces of the said deodorizing assembly 11, a ventilation area can be taken widely and it deodorizes in the state where the ventilation resistance is also low. And since the cold air flows almost uniformly from the entire top surface of the deodorizing assembly 11, the inflow speed thereof becomes gentle and the passing sound of the cold air is reduced.
[0052]
In this figure, the opening of the deodorizing cover 11a is provided only on the side surface of the deodorizing cover 11a. However, if an opening covered with eaves is additionally provided on the upper surface of the deodorizing cover 11a, the deodorizing cover 11a is further deodorized. It is obvious that the cold airflow above the upper surface of the assembly 11 becomes uniform, and that the cool air uniformly passes through the deodorizing assembly 11.
[0053]
Further, a part of the cold air flowing into the vegetable room 3 through the vegetable room cold air outlet 12 flows forward through a cold air passage formed by the partition part 5 and the vegetable room cover 24, and the remaining cold air is separated from the partition part 5 and the vegetable room. Since the cool air passage formed by the cover 24 flows rearward, the cool air flowing out from the deodorizing assembly 11 is dispersed back and forth, and the return cool air from the refrigerator compartment 2 flowing from the upper surface of the deodorizing assembly 11 becomes more uniform.
[0054]
The deodorizing assembly 11 includes a breathable container (for example, a cloth bag or a container made of non-woven fiber) and an appropriate amount of granular activated carbon, which is used as the deodorizing body 11b. 11b is inserted and covered with a deodorizing upper case 11d, and the deodorizing upper case 11d and the deodorizing lower case 11c are bonded.
[0055]
In addition, an antibacterial filter may be added to the deodorizing body 11b together with activated carbon to add antibacterial action, and carbon fiber may be used instead of granular activated carbon. Moreover, you may use an antibacterial fiber and an antibacterial resin for the container of the deodorizing body 11b, the said deodorizing upper case 11d, and the deodorizing lower case 11c.
[0056]
Further, the deodorizing body 11b includes a transition metal keyate compound having a chemical fiber having air permeability, a filter made of the fiber, or a chemical resin having a hole such as a honeycomb shape, a square shape, or a slit shape (for example, a porous nylon fiber or a resin). ) May be used. If the deodorizing assembly 11 is taken out and washed with water, it can be used for a long time.
[0057]
In addition, if the deodorizing body 11b, the deodorizing upper case 11d, and the deodorizing lower case 11c can be individually disassembled and reassembled with screws or claws, the replacement and washing with water becomes easier and the deodorization can be performed more cleanly. The effect can be maintained.
[0058]
In addition, at least a part of the upper surface of the deodorizing assembly 11 can be seen in accordance with absorption or decomposition of odor gas (for example, methyl red, cupric sulfate, ferrous sulfate, cobalt sulfate, etc.). If the display part is provided with a substance containing or a substance containing the substance coated with synthetic resin at an appropriate film pressure, the display part changes color according to the period of use of the deodorizing assembly 11, The use period, deterioration, and replacement time of the deodorizing assembly 11 of the deodorizing means can be understood at a glance, and the refrigerator and the deodorizing means can be maintained and replaced at an appropriate time, so that a deodorizing efficiency can always be maintained.
[0059]
The display unit is at least partially covered with a transparent cover having air permeability, is detachable from the deodorizing assembly 11, and when the deodorizing means is maintained or replaced, the display unit is newly It's a good idea to replace it with a new one. Moreover, you may provide the display part similar to the above in the said deodorizing body 11b.
[0060]
In addition, you may use the ozone deodorizing system by utilizing the ozone generator which has an insulating means in the said deodorizing means.
[0061]
In addition, the vicinity of the refrigeration chamber cold air return port 10 of the partition 5 is high so that water droplets generated in the refrigeration chamber 2 or liquids such as soy sauce accidentally spilled in the refrigeration chamber 2 do not leak to the lower vegetable chamber 3 side.

In FIG. 4, the cold air cooled by the cooler 25 is sent to the pressure chamber 28 by the blower 26, and sent from the pressure chamber 28 to the freezer compartment 31 through the freezer compartment cold air distribution passage 30. Thereafter, the cool air cools the stored items in the freezer compartment 31 and returns to the lower side of the cooler 25.
[0065]
Further, a temperature sensing unit (not shown) provided in the refrigerator compartment 2 senses the room temperature of the refrigerator compartment 2, and when the room temperature becomes higher than a predetermined temperature, a damper (shown by a dotted line) (Not shown) is opened, and the cold air that has entered the cold air distribution chamber 15 from the pressure chamber 28 passes through the cold air distribution passage 16 a and the ceiling-side cold air passage 17 and is sent to the refrigerating chamber 2 and the isolation chamber 4.
[0066]
Thereafter, the cool air cools the stored items in the refrigerator compartment 2 and the isolation chamber 4, passes through the deodorizing assembly 11, deodorizes the odor generated in the refrigerator compartment 2 and the isolation chamber 4, and is sent to the vegetable compartment 3. And the cool air deodorized with the deodorizing assembly 11 cools the stored thing in the vegetable compartment 3, and returns to the downward direction of the cooler 25 with a duct (not shown).
[0067]
The odor in the cold air that has returned from the vegetable compartment 3 or the freezer compartment 31 to the lower side of the cooler 25 is deodorized by a deodorizing heater 32 having a catalyst film layer below the cooler 25.
[0068]
As described above, since the cold air in the refrigerator compartment 2 and the isolation chamber 4 passes through the deodorization assembly 11, the deodorization assembly 11 can quickly deodorize the odors of stored products that are likely to emit strong odors such as fish in the isolation chamber 4. In addition, a large amount of odor emitted from the stored item in the refrigerator compartment 2 having a relatively high storage temperature can be directly deodorized by the deodorizing assembly 11 efficiently near the generation source, and a deodorizing heater 32 below the cooler 25. Compared with the case of only, the refrigerator in which the smell of the said isolation | separation room 4 or the refrigerator compartment 2 is hard to move to the store, duct, etc. of the vegetable compartment 3 is obtained. In addition, the arrow in a figure represents the flow of cold air.
[0069]
In addition, the above is an example when the cooler 25 is commonly used for cooling each storage room such as the refrigerator compartment 2, the isolation room 4, the vegetable room 3, the freezer room 31, and the like. Even in the case where there is a cooler (for example, a refrigerator corresponding to each of a refrigerator room, an isolation room, a vegetable room and a freezer room), the same installation of the deodorizing assembly 11 described above, The same deodorizing effect as described above can be obtained.
[0070]
In the above description, the left-right direction means the left-right direction when the refrigerator is viewed from the front, and the front-rear direction means the front-rear direction when the refrigerator is viewed from the front. Further, in this figure, hatching for a portion showing a thin cross section such as a plate thickness is omitted.

【The invention's effect】
Since the refrigerator of the present invention is configured as described above, it is possible to deodorize the odor in the refrigeration room at or near the refrigeration room cold air return port below the refrigeration room, so that the refrigerator with a relatively high storage temperature can be used. A refrigerator that can efficiently deodorize a large amount of odors emitted from a certain store near the source, and that makes it difficult for the odor in the refrigerator compartment to be transferred to other sources. In addition, there is a deodorizing cover that covers the deodorizing means at the top. When the spillage is spilled, the deodorizing means can be prevented from being directly applied, and the deodorizing means is located in the lower front of the refrigerator compartment, and the deodorizing means can be seen from at least a part of the deodorizing cover. It is easy to understand the time to care for the deodorizing means, and if the deodorizing cover and the deodorizing means are detachable, they can be easily removed from the refrigerator and the deodorizing means can be maintained. Easy refrigerator is obtained.
[0072]
In addition, since the odor in the refrigerator compartment can be deodorized at or near the refrigerator return outlet located in the partition between the refrigerator compartment and the storage compartment, the stored items in the refrigerator compartment having a relatively high storage temperature A large amount of odor generated from the odor can be efficiently and directly deodorized near the source, and a refrigerator can be obtained in which the odor of the refrigeration room does not easily transfer to the storage in the above storage room. When the liquid is spilled, it can be directly applied to the deodorizing means and leakage to the storage room under the refrigeration chamber can be prevented, and the deodorizing means is located at the lower front of the refrigeration chamber, and at least one of the deodorizing covers. If the deodorizing means can be seen from the section, deterioration of the deodorizing means can be seen, the maintenance time of the deodorizing means is easy to understand, and if the deodorizing cover and the deodorizing means are detachable, Easily taken out, care of the deodorizing means easy refrigerator is obtained.
[0073]
And when liquids, such as soy sauce, are spilled on the said deodorizing cover etc. of a refrigerator compartment, it accumulates in the said liquid pool, and the refrigerator which is hard to leak to others is obtained.
[0074]
Further, when liquid such as soy sauce is spilled into the refrigerator compartment, the liquid that has fallen on the partition flows to the liquid pool side, so that all the liquid pool on the partition is collected and a refrigerator that can be easily wiped off is obtained.
[0075]
Furthermore, when the refrigerator compartment door is opened, it is easy to see the puddle. If the puddle is filled with liquid, it can be wiped off immediately and the refrigerator compartment can be kept clean.
