Therefore, it is not necessary to attach a special light-shielding plate to the right side, and the defrost timer 66 is heated by the heat generated by the interior light 62, so that dew condensation or frost is generated on the defrost timer 66. Is also suppressed.

Further, on the front surface of the damper cover 51, there is integrally formed a frame-shaped protruding wall 71 which surrounds the cool air discharge port 52 and protrudes. The lower edge of the protruding wall 71 serves as a holding portion. The groove 72 and the engaging claws 73, 73, which also serve as holding portions, are integrally formed at two locations on the upper edge.
Further, as shown in FIG. 8, below the cold air discharge port 52 in the projecting wall 71, there is formed a notch 74 in which one side of the substantially U shape laid sideways and the upper side thereof further extends laterally. .

Due to such a shape, in the notch 74, there is an elastic holding piece 76 extending from left to right toward the right and having a predetermined elasticity, and a predetermined space is provided above the elastic holding piece 76. Then, another elastic sandwiching piece portion 77 extending from right to left so as to face each other and having a predetermined elasticity is integrally formed.

Further, on the lower side of the cut 74, the characters “weak”, “ice temperature”, and “strong” are printed from the left.

On the front surface of the damper cover 51, a plate-like shutter 86 which is located in the protruding wall 71 and is made of a hard synthetic resin such as polypropylene is attached. The shutter 86 is integrally formed with an opening 87 at an upper portion thereof, an operation portion 88 and a window 89 at a lower end front surface thereof, and an engaging projection 91 protruding rearward at a central portion of the rear surface. The opening 87 is composed of first to third openings 87A, 87B and 87C which are partitioned to the left and right as shown in the sectional view of FIG. Of these, the opening 87A on the left side has the largest opening area, and is directed toward the left,
The central opening 87B extends to the left and right and faces forward. In addition, the opening 87C on the right side is oppositely directed to the right.

Then, the lower end of the shutter 86 is inserted into and engaged with the groove 72 from the front of the damper cover 51, and the engaging projection 91 on the back surface is press-fitted between the elastic holding piece portions 77 of the elastic holding piece portion 76 as shown in FIG. While engaging, the upper edge of the engaging claw 73,
The shutter 86 is attached to the front surface of the damper cover 51 so as to be movable in the left-right direction and disengageably by pushing and engaging the back side of the 73. At this time, the operation unit 88
Is located below the container 41, and the window 89 corresponds to the above-mentioned character portion. That is, with such a configuration, the shutter 86 can be moved in the left-right direction within a predetermined range by pinching the operating portion 88 by hand. In particular, with the above configuration, the shutter 86 can be attached to the damper cover 51 from the front side of the damper cover 51, so that assembly workability and maintenance workability are significantly improved.

At this time, both elastic holding pieces 76 and 77 are slidably pressed against the upper and lower surfaces of the engaging projection 91, and the engaging projection 91 and the convex portion 81 and Between 84 (left), between 84 and 82 (middle), 8
2 and 83 (right) selectively enter, and in that state, the shutter 86 is stationary, and both elastic clamping pieces 76, 77 maintain their respective stationary states.

The first opening 87A is closed while the shutter 86 is moved to the left by the operating portion 88 as shown in FIG. 10, and the cool air discharge port 52 is provided with the second and third openings 87B and 87C of the shutter 86. Is opened (hatched in the figure; the same applies hereinafter). As a result, the cool air discharge port 5
The amount of cold air discharged from 2 is the smallest. And the window 8
9 corresponds to "weak" and exposes this character on the front surface. Further, the first opening 87A is half-opened while the shutter 86 is moved to the intermediate position by the operating portion 88 as shown in FIG. 11, and the other openings 87B and 87C are also opened. As a result, the cold air discharge amount from the cool air discharge port 52 becomes an intermediate amount. Then, the window 89 exposes this character on the front surface corresponding to the "ice temperature".

Furthermore, as shown in FIG. 3, the operation portion 88 moves the shutter 86 to the right and the first opening 87A.
Is fully opened, and the other openings 87B and 87C are also opened. As a result, the amount of cold air discharged from the cool air discharge port 52 becomes the maximum amount. Then, the window 89 exposes this character on the front surface corresponding to "strong".

A machine room 92 is formed in the lower part of the heat insulating box 3, and together with the cooler 31, a compressor 93 and an evaporating condenser 94, which constitute a well-known refrigerating cycle, and an evaporating dish 96 are provided. Is installed. On both sides of the machine room 92, base leg angles 97, 97 made of thick steel plate are attached to the heat insulating box 3, as shown in FIG.
Front legs 98 and 98 are attached to the lower surface of the front end portion of 97, respectively. Further, a compressor base 99 is attached to the rear parts of the two leg angles 97, 97 across them, and the compressor 93 is installed on the compressor base 99. The compressor base 99 has the same size as the front legs 98, 98 and projects downward, and these serve as the installation surface of the refrigerator 1. Also,
The evaporation condenser 94 is horizontally mounted in front of the compressor base 99 at substantially the same height as the base leg angles 97, 97, and the evaporation tray 96 is mounted on the evaporation condenser 94.

Below the evaporation condenser 94, a carrying handle 101 is attached. In this carrying handle 101, both ends of a metal pipe are crushed to form mounting portions 102 and 102, and a grip portion 103 located between both mounting portions 102 and 102.
Is bent downward in a substantially trapezoidal shape, and both mounting portions 102, 102 are fixed to both base leg angles 97, 97 from below by screws 104, so that the base leg angle 9
It will be installed between 7 and 97.

At this time, the carrying handle 101 has the front legs 98,
It is located below the evaporation condenser 94 on the rear side of 98 and in front of the center of the base leg angles 97, 97,
Also, the amount of downward protrusion of the handle portion 103 is determined by the front legs 98, 98.
Alternatively, it is smaller than the compressor stand 99. Therefore, since the carrying handle 101 does not contact the floor surface when the refrigerator 1 is installed, the refrigerator 1 does not become unstable. Further, since the carrying handle 101 is attached across the front portions of the base leg angles 97, 97 to reinforce the heat insulating box 3, the rigidity of the refrigerator 1 is improved, and the evaporation condenser 94 is installed from below. It also plays a role of protection.

When the refrigerator 1 is transported, the upper portion of the refrigerator 1 is tilted backward, and the upper portion of the rear face and the handle portion 103 of the transport handle 101 are used to transport the refrigerator 1. In this case as well, the transport handle 101 is a base leg. Since it is located in front of the angles 97, 97, it is easy to insert and hold a hand.

With the above configuration, the compressor 93 and the blower 33
Is operated, the liquid refrigerant discharged from the compressor 93 and condensed by the evaporation condenser 94 and the condenser (not shown) is depressurized and supplied, and evaporates internally, so that the latent heat from the surroundings is lost. Takes away the cooling effect.
The cool air cooled by the cooler 31 is sucked upward by the blower 33, and the freezing chamber 6 is discharged from the front cool air discharge port 34.
It is blown out inside. The cold air blown into the freezer compartment 6 is
After circulating and cooling there, it returns to the lower part of the cooler 31 from the lower cool air suction port 37. Compressor 93 and blower 33
Is controlled by a controller (not shown) based on the temperature of the freezing compartment 6, whereby the freezing compartment 6 is maintained at a predetermined freezing temperature (about -20 ° C).

Further, a part of the cool air blown out by the blower 33 flows into the distribution duct, descends there, passes through the cool air discharge duct 36, passes through the air outlet 46 and the damper device 47, and as described above. Cold room 7 from the cold air outlet 58
It is blown out inside. The cold air that has circulated in the refrigerating chamber 7 is cooled and then cooled through the cold air inlet 13
It flows into 9 and returns to the lower part of the cooler 31. Since the damper device 47 opens and closes the outlet 46 by the baffle plate 48 based on the temperature inside the refrigerating chamber 7, the temperature inside the refrigerating chamber 7 is maintained at a predetermined refrigerating temperature (about + 5 ° C.) by the damper device 47. .

On the other hand, a damper device 47 is installed in the ice greenhouse 43.
Since the cool air that has passed through is directly discharged and supplied from the cool air discharge port 52, the ice greenhouse 43 in the state of FIG.
It will be cooled to moderate ice temperature. Further, since the supplied cold air has passed through the damper device 47, the temperature of the ice greenhouse 43 depends on the temperature of the refrigerating compartment 7, but the volume of the ice greenhouse 43 is smaller than the volume of the refrigerating compartment 7. Therefore, the shutter 86 is used for fine adjustment of the temperature of the ice greenhouse 43.
It can be easily done by operating.

That is, when it is desired to set the temperature in the ice greenhouse 43 to the same high temperature as the refrigerating compartment 7, the operating portion 88 of the shutter 86 is pinched and moved to the left (FIG. 10). In this state, the opening 87A is closed as described above (the other openings 87B and 87C are opened).
From 2, the amount of cold air decreases. Therefore, the temperature of the ice greenhouse 43 becomes relatively high.

When it is desired to lower the temperature of the ice greenhouse 43 to bring it into an ice temperature state, the operating portion 88 is pinched and the shutter 86 is moved to the intermediate position (FIG. 11). In this state, since the opening 87A is in the half-opened state (the other openings 87B and 87C are open) as described above, the amount of cool air from the cool air discharge port 52 is slightly increased. Therefore, the temperature of the ice greenhouse 43 is in a slightly low ice temperature state.

When it is desired to further lower the temperature of the ice greenhouse 43, the operation portion 88 is pinched and the shutter 86 is moved to the rightmost (FIG. 3). In this state, since the opening 87A is fully opened as described above (the other openings 87B and 87C are also opened), a large amount of cool air is discharged from the cool air discharge port 52 into the ice greenhouse 43. Therefore, the temperature of the ice greenhouse 43 is relatively low.

In particular, since the openings 87A, 87B and 87C forming the opening 87 of the shutter 86 are oriented so as to spread in the left-right direction as described above, the cool air discharge port 5 is provided.
The cold air discharged from 2 is evenly blown into the ice greenhouse 43. Therefore, the occurrence of temperature unevenness in the ice greenhouse 43 is also suppressed.

Therefore, assembly workability and maintenance workability are significantly improved. In particular, since the components for adjusting the discharge amount of cold air can be integrated into one component of the shutter, the number of components can be significantly reduced and the cost can be reduced.

According to the second aspect of the present invention, the interior light and the defrost timer are provided inside the damper cover, and the light transmitting portion is formed at least in front of the interior light. Compared to the case where a timer is installed in the machine room, there is less risk of contamination and failure, and when setting and maintaining the defrost timer, do it from the inside of the refrigerator without turning to the back of the refrigerator one by one. Will be able to. Therefore, it becomes possible to remarkably improve these workability. In particular, since the defrost timer is arranged above the interior light, the light emitted upward from the interior light can be blocked by the defrost timer. Therefore, it is not necessary to attach a special light shielding plate, and the defrost timer is heated by the heat generated by the interior light, so that the occurrence of dew condensation or frost on the defrost timer is suppressed.

Further, according to the invention of claim 3, among the plurality of through holes formed in the molded heat insulating material corresponding to the cold air suction port on the lower surface of the partition wall, a step-like shape is formed above the through hole located at the center. Since the expansion portion is formed and the deodorizer is fitted and installed in the expansion portion, the deodorizer can be attached only by fitting from above into the expansion portion. Therefore, it is not necessary to attach a special case or the like, and it is possible to improve the assembly workability and reduce the cost by reducing the number of parts. In particular, since the deodorizer is attached to the through hole located in the center of the molded heat insulating material, it is possible to efficiently and uniformly exert the deodorizing effect while suppressing the increase of the circulation resistance of the intake cold air to the minimum. .
