  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the operation of the refrigeration cycle will be described. The refrigeration cycle is operated by a signal from the control means in accordance with the set temperature in the refrigerator, and the cooling operation is performed. The high-temperature and high-pressure refrigerant discharged by the operation of the compressor 109 is condensed to some extent by a condenser (not shown), and further, refrigerant piping ( (Not shown) and the like, condensate into liquid while preventing condensation on the refrigerator main body, and reaches a capillary (not shown). Thereafter, the capillary is depressurized while exchanging heat with a suction pipe (not shown) to the compressor 109 to become a low-temperature and low-pressure liquid refrigerant and reaches the cooler 112. Here, the low-temperature and low-pressure liquid refrigerant exchanges heat with the air in each storage chamber by the operation of the cooling fan 113, and the refrigerant in the cooler 112 evaporates. At this time, cool air for cooling each storage chamber is generated in the cooling chamber 110. The low-temperature cold air is diverted from the cooling fan 113 to the refrigerating room 104, the switching room 105, the ice making room 106, the vegetable room 107, and the freezing room 108 using an air passage or a damper, and cooled to respective target temperature zones. In particular, the vegetable compartment 107 cools the refrigerator compartment 104 and then discharges it to the vegetable compartment 107 from a vegetable compartment outlet 124 formed in the middle of the refrigerator compartment return air passage for circulating the air to the cooler 112. Then, the air flows through the outer peripheries of the upper storage container 120 and the lower storage container 119 to indirectly cool, and then returns to the cooler 112 again from the vegetable room suction port 126. In addition, the temperature control of the vegetable compartment 107 is performed by ON / OFF operation of the distribution of cold air and the partition wall heater 154 provided on the partition wall, and adjusted to 2 ° C to 7 ° C by these controls. Has been. In general, there are many that do not have an internal temperature detection means.

  A recess is formed in the rear partition wall 200 installed in the rear surface of the vegetable compartment 107, and an electrostatic atomizer 131 is attached to this portion. Here, the rear of the metal pin 134 which is the atomization part 139 has the deepest recessed part 200b, and the thickness of a heat insulating material is comprised by about 2 mm-10 mm, for example, and it becomes a low temperature state from another location. In the refrigerator according to the present embodiment, such a thickness is appropriate as a heat relaxation member positioned between the metal pin and the adjusting means. As a result, the rear partition wall 200 has a concave portion 200a, and the electrostatic atomizer 131 having a shape in which the convex portion 134a of the metal pin 134 protrudes is fitted into the deepest concave portion 200b on the rearmost surface of this portion. It has been.

  In the freezing chamber discharge air passage 141 on the back surface of the metal pin 134, cool air is generated by the cooler 112 by the operation of the refrigerating cycle, and cool air of about −15 to −25 ° C. is discharged by the cooling fan 113, and heat conduction from the air passage surface. The metal pin 134 is cooled to about 0 to -10 ° C. At this time, since the metal pin 134 is a good heat conduction member, it is very easy to transmit cold heat, and the atomizing electrode 135 fixed to the metal pin 134 is also cooled to about 0 to −10 ° C. via the metal pin 134. The

  Here, the vegetable room is 2 ° C to 7 ° C and maintains a relatively high humidity state due to transpiration from vegetables, etc., so the atomization electrode 135 which is the atomization tip is below the dew point and includes the tip. Water is generated on the crystallization electrode 135 and water droplets adhere thereto.

  At this time, water vapor generated by transpiration from foods with relatively high water content stored in the lower storage container 119, such as Chinese cabbage, spinach, lettuce, etc., passes through the gap between the lower part of the upper storage container 120 and the upper part of the lower storage container. It flows out to the back surface partition wall part 200. Here, since the upper rib 161 and the lower rib 162 are configured continuously in the left-right direction in the up-down direction, it is difficult for the water vapor that has flowed out to escape, so that the vicinity of the electrostatic atomizer 131 is relatively Maintains high humidity.

  In addition, when cold air flows into the vegetable compartment 107 from the vegetable compartment discharge port 124, it mainly passes through the space between the lid 122 and the first partition wall 123, and the door of the upper storage container 120. The stored beverage storage portion 166 in the front portion of the lower storage container 119 enters the front storage portion 119 from the front side.

  Further, a part of the cold air from which the cold air flows into the vegetable chamber 107 from the vegetable chamber discharge port 124 enters the lower storage container 119 through the gap between the bottom surface of the upper storage container 120 and the upper rear surface of the lower storage container 119, The internal stored food is cooled, but this flow is a part, and the internal stored food is mainly cooled by the lid 122 and the first partition wall which are the space on the upper side of the lid 122. 123 is performed from a portion entering the front portion of the lower storage container 119 from the front portion on the door side of the upper storage container 120.

  In addition, the portion of the lid 122 that faces the vegetable chamber discharge port 124 has an inclined portion 122a so that the cold air flowing in from the vegetable chamber discharge port 124 tends to move forward. Since it is shaped to guide the flow of cold air further forward and upward by making contact with the inflow of cold air at an obtuse angle, the cold air that has flowed in from the vegetable room discharge port 124 is more closely connected to the lid body 122. It becomes easy to pass between the one partition wall 123 and enters a large amount into the stored beverage storage portion 166 in the front portion of the lower storage container 119 from the front portion on the door side of the upper storage container 120.

  In this way, the cold air introduction path from the vegetable compartment discharge port 124 to the storage container mainly receives cold and dry cold air from the stored beverage storage part 166 in the front part of the lower storage container 119, so that those cold and dry For example, a beverage such as a plastic bottle stored in the front portion of the lower storage container 119 is cooled with cold air, and then the lower storage container 119 passes through the lower storage container 119 so that the cool air having a relatively high humidity becomes the upper storage container 120 and the electrostatic atomizer. It will flow into the vicinity of 131. Therefore, the humidity on the front side of the vegetable room, that is, the back side can be made relatively higher than the door side, so that the periphery of the electrostatic atomizer 131 arranged on the back side becomes an atmosphere of high humidity and electrostatic atomization. The apparatus 131 can create an environment where moisture in the air is likely to condense.

  Further, when the door is closed, the back cover engaging portion 122b on the back side of the cover body 122, the upper storage container 120 and the upper storage container engaging section 120a engaging with the back cover engaging portion 122b are mutually connected. Since it is tilted, the collision sound generated when closing the door is generated only when the door is completely closed. When the back cover engaging portion 122b and the upper storage container engaging portion 120a are not inclined, the door starts to collide before it is completely closed. There is a concern that makes users feel anxious. On the other hand, in the present embodiment, since the engagement portion is inclined, the back lid engagement portion 122b and the upper storage container engagement portion 120a are engaged only when the door is completely closed. No collision sound is generated when the door is closed, and the user is not anxious and the door can be closed smoothly.

  Further, the flange 122c extending downward is provided at the end of the lid 122 on the side of the vegetable chamber discharge port 124, so that the cold air that is dried at low temperature flowing in from the vegetable chamber discharge port 124 is directly applied. Inflow to the upper storage container 120 is prevented, and the high humidity environment of the upper storage container 120 is maintained.

  Moreover, it flows out out of the vegetable room from the suction port 126 for vegetable rooms located in the most downstream of the cold air | flow which flows through the vegetable room.

  In addition, when cold air does not flow into the vegetable compartment 107 from the vegetable compartment discharge port 124, moisture evaporates from the food stored in the lower storage container 119 with the passage of time from the time of charging. At this time, the air containing the evaporated water flows along the side of the lower storage container 119 where the electrostatic atomizer 131 is arranged along the flow of the cold air flowing into the lower storage container 119 (this embodiment). Then, it flows out of the storage container from the cool air outflow portion which is the largest gap among the gaps defined by the bottom storage container 119 and the bottom surface of the upper storage container 120, The wind direction is changed by the upper rib 161 which is a humidity introducing means provided continuously in the left-right direction and reaches the vicinity of the electrostatic atomizer 131.

  At this time, in the present embodiment, the electrostatic atomizer 131 is arranged on the right side where the vegetable room suction port of the vegetable room 107 is arranged, and the upper rib 161 is arranged on the left side of the electrostatic atomizer 131. By pulling the cold air from the vegetable room suction port, the humidity on the right side of the vegetable room suction port side is relatively higher than that on the left side, so the electrostatic atomizer 131 is used for the vegetable room 107 in the vegetable room. By arrange | positioning at a suction inlet, the surroundings of the electrostatic atomizer 131 can be made higher humidity, and it becomes possible to make it easy to dew the water | moisture content in air. Further, it is desirable that upper ribs 161 are provided on both sides of the electrostatic atomizer 131, thereby preventing the high-humidity cold air from leaking upward, and making the periphery of the electrostatic atomizer 131 high humidity. be able to.

  In this way, the electrostatic atomizer 131 arranged in a high humidity atmosphere has its interior cooled below the ambient temperature by heat conduction from cold air at a temperature lower than that of the adjacent vegetable compartment. Moisture in the air will condense inside the electroatomizer 131. The condensed water is sprayed in a mist form inside the storage container. As a result, the transpiration water from the stored food is returned to the stored food itself again by the electrostatic atomizer 131. Therefore, the cooling means for cooling the electrostatic atomizer 131 must be a space in which cool air in a lower temperature zone flows than the storage chamber in which the electrostatic atomizer 131 is provided. Even when the air passage is not used, for example, the cold air of the storage room in the adjacent low temperature zone (for example, the freezing temperature zone) may be used.

  At this time, it goes without saying that the space in the lower storage container 119 where the mist is directly sprayed by the electrostatic atomizer 131 becomes an atmosphere of high humidity, but in the upper storage container 120 located above the lower storage container 119. The mist sprayed by the electrostatic atomizer 131 also reaches this space, resulting in a high humidity space.

  This is because the upper storage container 120 is partly disposed on the bottom side in the lower storage container 119, and a plurality of air flow holes 71 are formed in the upper storage container 120 disposed in the lower storage container 119. Since the mist filled in the lower storage container 119, the mist having a small particle diameter and flying diffusively flows into the space in the upper storage container 120 from the air circulation hole 71, and the upper part is the lid. Since humidity does not easily flow out from the space in the upper storage container 120 closed by 122, high humidity can be maintained.

  Further, as shown in FIG. 3d, the upper storage container 120 has a handle portion 120b, and this portion becomes an opening, but in the cold air path in the vegetable room as shown in FIG. 122 is pulled by the flow of the cold air flowing downward from the upper side of 122, the outflow is larger than the inflow of the cold air into the upper storage container 120 from the handle portion 120b which is this opening, substantially. It becomes an outlet for cool air from the upper storage container 120.

  Therefore, when the plurality of air circulation holes 71 provided on the side surface or the bottom surface of the upper storage container 65 are used, the high humidity cold air flows in and flows out from the handle portion 120b, and the handle portion 120b by the opening portion is provided. However, it is possible to maintain high humidity by having a structure in which the dry cool air hardly flows into the upper storage container 120.

  Further, the upper storage container 120 is provided with a lid 122, which prevents inflow of a relatively low temperature of cold air, and also has a relatively high temperature rising upward from the lower storage container 119 as described above. Since the space in the upper storage container 120 is cooled by humidity and cold air, in addition to improving the freshness, it is possible to prevent low-temperature damage, and in particular, vegetables and fruits that are susceptible to low-temperature damage are stored in the upper storage container 120. Then, it becomes possible to make vegetables and fruits last longer in a fresher state.

  In addition, since the bottom portion of the upper storage container 120 has a corrugated shape formed in a concavo-convex shape, the mist particles enter the vegetables and fruits in the upper storage container 120 not only from the top and side surfaces but also from the bottom surface. Moisturizing can be performed, and mist particles can be filled around vegetables and fruits from more diverse directions, and the freshness can be further improved.

  Furthermore, in this embodiment, the concave portion or the convex portion continues in the left-right direction of the upper storage container 120 so that this wave shape is substantially parallel to the flow of cold air flowing from the air circulation hole 71 provided on the side surface. In preparation. This makes it easier for cold air containing mist flowing in from the air circulation hole 71 to wrap around the bottom surface portion, so that the freshness can be further improved.

  As described above, in the present embodiment, the flow of cold air in the vegetable compartment is controlled and used properly. First, cold air dried at low temperature is put in a large amount in the stored beverage storage part 166 in the front part where beverages such as PET bottles are often placed, and low temperature cold air is directly touched, ensuring a cooling speed, Next, as the cold air that flows in from the front side of the vegetable room flows to the back side, the humidity increases, so the humidity on the back side is relatively higher than the door side. The surroundings of the atomizer 131 can be made into an environment in which moisture in the air is likely to condense in the electrostatic atomizer 131 as a high humidity atmosphere. Furthermore, the mist sprayed by the electrostatic atomizer 131 using the water droplets in which moisture in the storage room is condensed becomes a fine mist having a fine particle diameter and high diffusibility, and fills the lower storage container 119. Further, the mist having a small particle size and high diffusibility flows into the upper storage container 120 located at an upper position where the temperature is higher than that at the lower position so as to perform moisture retention.

  By controlling the flow of the cold air in this way, the stored items to be cooled quickly are stored in the stored beverage storage unit 166 in the front portion, and general vegetables and fruits that are relatively less susceptible to low-temperature failures are stored in the lower storage container 119. By storing vegetables and fruits that are more susceptible to low-temperature damage in the upper storage container 120, it is possible to perform cooling suitable for each stored item, and to create a vegetable room with higher quality and improved freshness It becomes possible to provide.

  Further, in the case where cold air does not flow from the vegetable room discharge port 124 as described above, even if the damper located upstream from the vegetable room discharge port 124 is closed on the air passage, generally the vegetable room Since a damper is not provided downstream from the suction port 126, a cool air flow is generated from the inside of the lower storage container 119, which is a storage container, toward the vegetable room suction port 126, although little by little. However, since the lower rib 162 is provided above the suction port 126 for the vegetable room, the air containing the evaporated water does not go directly to the suction port 126 for the vegetable room, and is partitioned by the upper rib 161 and the lower rib 162. Held in the space. Therefore, in the space defined by the upper rib 161 and the lower rib 162, high-humidity cold air stays and collects in the vicinity of the electrostatic atomizer 131, so that the electrostatic atomizer 131 can easily collect moisture.

  Thereby, since the atomization electrode 135 of the electrostatic atomizer 131 provided in the high-humidity atmosphere becomes easy to condense, the generation efficiency of mist becomes high.

  Next, operation | movement and an effect | action are demonstrated about the structure of the 2nd partition wall 125 which partitions off the vegetable compartment 107 and the freezer compartment 108. FIG.

  The upper surface space of the second partition wall 125 is the vegetable compartment 107, and the inside of the vegetable compartment 107 is maintained at a high humidity by the sprayed mist. For this reason, there is a problem that dust and impurities in the vegetable compartment 107 are likely to adhere to the surface of the second partition wall 125 due to mist and circulated cold air, and are easily contaminated.

  For this reason, the structure which the rear part partition wall 125b which occupies most of the lower surfaces of the lower storage container 119 can be easily attached and removed without a tool is desired.

  When removing the second partition wall 125, the front partition wall 125a and the rear partition wall 125b are connected by a rivet member 175, so that the user grasps and rotates the convex portion 175a, so that the base 175b When the claw portion 175c gets over the protruding portion 171c, the locked state of the rivet member 175 is released and the rivet member 175 can be rotated. At the same time, the locking portion 175e is released from the engaged state with the inclined wall 177 by the rotating operation of the rivet member 175. Thus, the connected state of the front partition wall 125a and the rear partition wall 125b can be released.

  Since all the rivet members 175 can be manually operated by the user to release the fixing of the rear partition wall 125b as described above, the user can remove it without using a tool or the like, and it is easy to use. With the chamber 107 opened together with the drawer-type vegetable chamber door 118, the rear partition wall 125b can be removed from the front partition wall 125a by putting the hand inside the vegetable chamber 107, so that the surface contaminated by mist spraying can be removed. Can be cleaned.

  The freezer compartment 108 also has a drawer-type freezer compartment door 108a on the front, a lower storage container 108b inside, and an upper storage container 108c above the lower storage container 108b. The freezer compartment door 108a is opened and closed in the front-rear direction. In operation, the food stored in the upper storage container 108c may be opened and closed while sliding on the lower surface of the second partition wall 125. For this reason, the lower partition frame forming the lower surface of the second partition wall 125 172 may be frosted and may remain on the lower partition frame 172 while frosting. Even in such a case, the frosting state can be washed away by removing the rear partition wall 125b and washing it.

  When the rear partition wall 125b is fixed to the front partition wall 125a, the second partition wall 125b of the rear partition wall 125b is placed on the first step 173 of the front partition wall 125a while being pressed to a predetermined position of the first rear partition wall 111. The step 174 is wrapped, the rivet member 175 is passed through the opening 171 b of the upper partition frame 171, the other end side locking portion 175 e is penetrated into the hole 176 of the second step 174, and the user protrudes By picking and rotating 175a, the inclined wall 177 smoothly engages with the inclined portion 175g of the rectangular engaging portion 175e, so that the engaging portion 175e is not excessively stressed and the surface of the engaging portion 175e An engagement relationship can be formed with the inclined wall 177. Therefore, the rear partition wall 125b is prevented from coming off from the front partition wall 125a, and the projection 171c moves on the inclined portion 175f to get over the claw 175c, and the claw 175c and the projection 171a rotate the rivet member 175. It becomes a blocking structure and becomes an engagement fixed state.

  Accordingly, the protrusion 171c of the rear partition wall 125b and the claw portion 175c of the rivet member 175 prevent the rivet member 175 from rotating, and the inclined wall 177 of the front partition wall 125a and the locking portion 175e of the rivet member 175 provide a rear portion. The partition wall 125b can be prevented from coming off, and the rear partition wall 125b can be pressed against and fixed to the front partition wall 125a, thereby increasing the strength.

  As described above, the user can easily attach and detach the rear partition wall 125b by rotating the rivet member 175 using a hand without using a tool or the like, and further wash the removed rear partition wall 125b. be able to.

  In the case of the refrigerator of the embodiment, since the freezer compartment 108 is configured below the vegetable compartment 107 via the second partition wall 125, the cold heat in the freezer compartment 108 is transferred to the vegetable compartment via the second partition wall 125. There is a possibility that the inside of the vegetable compartment 107 is supercooled due to heat conduction to 107 and the food inside is frozen.

  For this reason, a heater member 184 such as an aluminum foil heater or a surface heater may be disposed between the heat insulating member 170 of the rear partition wall 125b and the resin upper partition frame 171.

  In this case, a resin protective plate member 185 that insulates the heater member 184 is disposed between the heater member 184 and the heat insulating member 170.

  In this case, when the rivet member 175 is removed, the heat insulating member 170 and the lower partition frame 172 are removed while the upper partition frame 171, the heater member 184, and the protection plate member 185 are attached without being removed from the rear partition wall 125 b. In particular, when the freezer compartment door 108a of the freezer compartment 108 is pulled back and forth repeatedly, the food in the upper storage container 108c comes into contact with the lower surface of the rear partition wall 125b and the frosted state of the lower partition frame 172 Can be wiped off or washed away.

  Further, by pulling the drawer door 108a of the freezer compartment forward, the lower storage container 108b can be pulled out of the room, and the second back partition wall 180 can be removed. Specifically, the claw portions 181a and the back partition wall back surface member 183 provided on both sides and the bottom of the second back partition wall surface member 181 of the second back partition wall 180 that forms the back surface of the freezer compartment 108. Since the claw hooking portion 183a is locked, the service person manually releases the locking structure on both sides and the lower portion without using a tool or the like when servicing the cooling chamber 110, and the inside of the cooling chamber 110 is Can be checked.

  Then, by moving the second rear partition wall surface member 181 whose both-side and lower locking structures are released downward, the second rear partition wall from the lower part of the first rear partition wall surface member 151 is moved downward. The upper claw portion 181a of the surface member 181 can be pulled out, and the second back partition wall surface member 181 can be removed.

  Then, the 2nd heat insulating material 182 can be removed and a part of back surface partition wall back surface member 183 is exposed.

  A return air passage 183b for the refrigerator compartment 104, the switching chamber 105, the ice making chamber 106, and the vegetable compartment 107 is formed on the side of the exposed rear partition wall rear surface member 183. Further, the return air passage 183b, the cooling chamber 110, The cool air return port 183c is formed.

  Then, the user can remove the second rear partition wall 180 as described above, and can see the inside of the cooling chamber 110 from the cold air return port 183c of the exposed rear partition wall rear surface member 183. The frosting state of the arranged cooler 112 can be directly checked, and in the case of abnormal frosting, enlightenment can be performed so as to suppress food stuffing into the cabinet.

  Moreover, since the back surface partition wall 200 is connected and fixed up and down by two parts of the 1st back surface partition wall surface member 151 and the 2nd back surface partition wall surface member 181, the 1st, 2nd back surface partition wall The strength of the surface members 151 and 181 can be increased.

  In addition, although the back surface partition wall back surface member 183 was set as the structure integrally formed with respect to the 1st back surface partition wall surface member 151 and the 2nd back surface partition wall surface member 181 which are arrange | positioned ahead, back surface partition wall back surface The member 183 is a separate upper and lower part corresponding to the first back partition wall surface member 151 and the second back partition wall surface member 181, and the upper back partition wall back surface member 183 d and the lower back partition wall back surface member 183 e are also used. Well, by this, if the lower back partition wall back surface member 183e behind the second back partition wall surface member 181 is removed after the second heat insulating material 182, the serviceman can directly visually recognize the downstream side of the cooler 112 in full width. Furthermore, since the frost state can be easily checked, the service time can be shortened, and the quality of the food that has been taken out can be maintained.

  In the present embodiment, the arrangement correlation between the vegetable compartment 107 and the freezer compartment 108 is that the vegetable compartment 107 is the upper compartment and the freezer compartment 108 is the lower compartment, but the vegetable compartment 107 is the lower compartment and the freezer compartment 108 is Even in the case of the upper chamber, the partition wall that divides the vegetable chamber 107 and the freezing chamber 108 up and down can be removed without a tool, and a part of the rear partition wall that partitions the cooling chamber 110 can be removed to remove the inside of the cooling chamber 110. Can be visually checked, and serviceability can be improved.

  In the present embodiment, the second partition wall 125 can be attached and detached without a tool, but the back surface of the first partition wall 123 or the third partition wall 190 that partitions the refrigerator compartment 104 and the switching chamber 106 up and down. If the rear surface partition wall 200 is formed over the distance, when the refrigerator 100 is assembled, after the rear surface partition wall 200 is assembled, the first partition wall 123 or the third partition wall 190 is assembled. Furthermore, the refrigerator which comprised the 1st partition wall 123 or the 3rd partition wall 190 so that attachment or detachment was possible without a tool is attained.

  As described above, the refrigerator according to the present invention can be applied not only to household or commercial refrigerators, but also to uses such as a multi-stage refrigerator.
