As a result, the inside of the vegetable compartment (23) is also cooled to a low temperature, which is slightly higher than + 5 ° C.

Two filter members (30) of the present application are arranged side by side on the partition plate (13). FIG. 1 is a sectional view of the partition plate (13) of the filter member (30), and FIG. 2 is a perspective view of the partition plate (13). Two rectangular recesses (31) are formed on the left and right sides of the partition plate (13), and rectangular through holes (32) are further formed on the bottom thereof. The edge portion of the through hole (32) is slightly bent upward, and the edge portion of the through hole (32) between the bent portion (33) and the peripheral side wall (34) of the recess (31) continuously rises upward. An open groove (35) is formed in the opening. Further, a continuous jetty (36) is provided around the outside of the recess (31) with a small clearance. The filter member (30) is fourth
As shown in the drawing or the exploded view of FIG. 5, each is composed of a synthetic resin filter case (38) and a filter body (39). For the filter body (39), for example, a film (41) made of polyvinyl alcohol having a thickness of about 150 μ is fitted into a lattice-shaped molding die, and synthetic resin is injected into the die and cured to form a lattice-shaped frame on the film (41). It is formed by molding.
The filter case (38) is provided with a plurality of ventilation holes (42) in a rectangular plate-like portion (43), and the lower surface of the plate-like portion (43) has front and rear edges and left and right edges in FIG. A hanging wall (44) projecting downward from a position slightly inward of the part is formed, and further front and rear hanging walls
(44) At the lower end of the inner surface, holding grooves (45) facing each other and holding the filter body (39) in a removable manner are formed. By inserting the filter body (39) into the holding groove (45) from the right side in FIG. 4 or FIG. 5 as indicated by the solid arrow, the filter body (39) is inserted into the plate case (43) in the filter case (38). )
The filter member (30) is constructed by holding it at a small distance below. Next, as shown by the broken line arrow in FIG.
The filter member (30) is covered in (31). This state is the first
As shown in the figure. At this time, the hanging wall (44) is in contact with the inner surface of the peripheral side wall (34), and the lower end thereof is in contact with the bottom surface of the groove (35). Also, the edge of the plate-shaped part (43) is in contact with the upper surface of the partition plate (13), and
6) The shape is that it is housed in the inside of the housing 6 exactly, so that the through hole 32 and the groove 35 are covered by the filter member 30. Furthermore, a film of the filter body (39) is provided in the through hole (32).
(41) is supported. As a result, the inside of the vegetable compartment (23) communicates with the inside of the refrigerating compartment (5) above only through the film (41).

Here, the film (41) has improved water retention by laminating fibrous polyvinyl alcohol, and further has nonuniform fine pores formed therein. In addition, since polyvinyl alcohol itself is hydrophilic, the humidity in the vegetable compartment (23) is 90% due to the water vapor emitted from the fruits and vegetables stored in the vegetable compartment (23).
When it is more than%, the film (41) absorbs and holds the water in the vegetable compartment (23). Furthermore, this moisture is stored in the refrigerator compartment of the film (41).
It moves to the (5) side, is dried, and is discharged into the refrigerating chamber (5) having a low partial pressure of water vapor. Further, when the humidity in the vegetable compartment (23) decreases, it also has a function of returning the retained water to the vegetable compartment (23).
As a result, the humidity in the vegetable compartment (23) is maintained at a high humidity of about 90%, which is optimum for storing fruits and vegetables of this kind, and the deterioration of quality of vegetables and the like due to overdrying is prevented. In addition, since the filter member (30) is provided on the partition plate (13), which is the contact point with the cold room (5) having a low temperature and is most susceptible to dew condensation, dew condensation on this part is effectively prevented and fresh vegetables It can be stored for a long time in the state. In addition, even if liquid dirt that has dropped onto the partition plate (13) enters the hanging wall (44) direction from the gap between the plate-like portion (43) of the filter case (38) and the partition plate (13), Since it is stored in 35), it does not enter in the direction of the filter body (39) and the clogging of the film (41) due to it does not occur. Furthermore, even if the film (41) is directly contaminated from the ventilation hole (42), only the filter member (30) is lifted upward from the partition plate (13) and removed, and only the filter body (39) is pulled out. Since it can be cleaned, it is not necessary to remove the entire partition plate (13) as in the conventional case, and cleaning can be easily performed. Further, since the filter body (39) is supported away from the plate-like portion (43), it is difficult to directly touch the film (41) itself even if foreign matter enters through the ventilation hole (42), and thus the film (41) It is difficult for a damage accident to occur.

(G) Effect of the Invention According to the present invention, since the recess is formed in the partition plate and the groove is provided in the peripheral edge of the through hole formed in the bottom of the recess, the peripheral side wall forming the recess and the filter member are formed. Even if sewage in the refrigerating room enters into the recess through the gap between and, it can be stopped by this groove part, and the vegetable room (particularly the vegetable container) below the partition plate from the through hole.
It is possible to prevent sewage from dripping inside. Also, since the filter member is detachably attached to the recess formed in the partition plate,
The filter member can be made compact, and the recess can be exposed by removing the filter member, and the recess, especially the groove can be cleaned and the filter body can be cleaned. Not only can the condition be maintained, but the food in the container can be managed hygienically. Further, since the filter member is provided with a predetermined space between the filter body and the ventilation hole of the case, the water absorbed by the filter body is brought into contact with the dry cold air circulating in the refrigerating room at this space to enter the refrigerating room. It can be released, and it is possible to suppress not only the humidity of the vegetable compartment but also the drying of the refrigerator compartment.
