Description

Refrigerator {Refrigerator}

The present invention relates to a refrigerator, and is particularly suitable for a refrigerator having a fan for circulating cold air in the refrigerator compartment.

As a conventional refrigerator, for example, as described in Japanese Patent Application Laid-Open No. Hei 8-240373, in order to provide a refrigerator capable of uniformly cooling each part of the refrigerating compartment, a storage compartment composed of a refrigerating compartment and a freezing compartment and a storage compartment are respectively provided. An evaporator for heat exchange with the cold air installed and blown, a blower fan disposed adjacent to the evaporator to supply the cold air heat exchanged by the evaporator to the storage compartment, and the discharge of the cold air installed at one side of the refrigerating compartment and heat exchanged by the evaporator It is known to provide a cold air discharge means for a refrigerating chamber which changes the direction and discharges to specify and concentrate the dispersion or discharge direction (prior art 1).

As a conventional refrigerator, for example, as described in Japanese Patent Application Laid-Open No. Hei 9-42820, a refrigerator provided with a blower for circulation of indoor cold air in a refrigerating chamber of a forced-air cooling system is used for averaging the room temperature. For the purpose of realizing stabilization of food preservation quality, the cold air circulation duct provided in the up-down direction in the inner center part of the refrigerating chamber, the cold air circulation blower provided in the lowest part in the duct, and the inside of the cold air circulation duct at predetermined intervals. It is known to equip both ends with the cold air discharge duct provided in the up-down direction, and to operate the cold air circulation blower at the time of stop of a compressor and a fixed time after opening / closing a door (prior art 2).

However, in the prior art 1, the cold air cooled by the evaporator is significantly lower than the temperature of the storage compartment, and when such low temperature cold air is intensively supplied into the refrigerating compartment and directly flushed to the storage, the storage, in particular, is already stored. There is a fear that the stored stock is excessively cooled, and sufficient consideration has not been given to the effect of the cold cooled by the evaporator on the food, which is the stock.

In addition, in the case of the prior art 2, when the door is opened and closed, and a hot storage material is carried in and a nonuniformity of the temperature distribution occurs in the refrigerating chamber, the hot storage is cooled in a short time, and the temperature distribution in the refrigerating chamber is uniformed in a short time. There was not enough consideration to do it.

An object of the present invention can reliably cool a refrigerating compartment with a cold chiller cooled by a cooler and at the same time refrigerate a newly stored hot food or the like without excessively cooling foods that have already been stored and deteriorated to a storage compartment temperature. It is an object of the present invention to provide a refrigerator which can be cooled in a cold manner in a short time, and can be cooled in a short time, and in which the temperature distribution in the refrigerating chamber can be uniform.

The vegetable compartment 6 and the freezer compartments 7 and 8 are partitioned by a heat insulation partition wall 15 having heat insulation to reduce heat transfer between the two chambers. At the rear of the vegetable chamber 6 and the freezing chambers 7 and 8, the cooler chamber 18 in which the cooler 16 and the cooling fan 17 are arrange | positioned is formed. The heat insulation partition wall 15 is extended in the up-down direction from the rear of the vegetable chamber 6 so that the said heat insulation partition wall 15 may be interposed between this cooler chamber 18 and the vegetable chamber 6. As shown in FIG. 1, the cooler chamber 18 is disposed over the rear of the vegetable compartment 6 and the freezer compartments 7 and 8, and the freezer compartments 7 and 8, which are the lower draw-out storage chambers, and the refrigerating chamber above them. It is formed in order to use the invalid space effectively when arranging the vegetable compartment 6 which is a draw-out storage chamber between (5). The cooler 16 constitutes a refrigeration cycle with a compressor 90, a condenser, and the like.

In the cooler chamber 18, a cooler fan 17 is disposed above the cooler 16. A cold air passage 19 is formed above the cooler chamber 18 and communicates with the refrigerating chamber 5 and the cooler chamber 18 and flows cold air cooled by the cooler 16 therein. The cold motor is supplied to the refrigerating chamber 5 through the cold air passage 19 by the fan 17 which rotates by the fan motor 20 installed in the rear side of the fan). The cold air passage 19 is provided with a damper flap 21 for adjusting the amount of cold air supplied to the refrigerator compartment 5 in order to adjust the temperature of the refrigerator compartment 5 to an appropriate range. Moreover, this damper flap 21 is provided in the cold air passage 19 in the heat insulating material arrange | positioned at the part used as what is called ceiling above the cooler chamber 18. As shown in FIG.

In addition, the cold air cooled by the cooler 16 flows outward from the fan 17 at the same time, and the cold air passage 22 disposed between the cooler chamber 18 and the vegetable chamber 6 or the freezing chambers 7 and 8. Lower the flow into the freezer compartment (7, 8) to cool the freezer compartment (7, 8).

After passing through the damper flap 21 through the damper flap 21, the cold air which passes through the damper flap 21 from the cooler chamber 18 raises the back side of the refrigerating chamber 5 along the wall surface of the inner housing 3. The cold air passage 19 is formed so that it may become. The cold air passage 19 is branched into a plurality of passages 19a and 19b at the rear of the refrigerating chamber 5. These branched cold air passages 19a and 19b extend upward and downward on both rear side portions of the refrigerating chamber 5. In the refrigerating chamber 5, the shelf 23 arrange | positioned in multiple at intervals in the up-down direction is arrange | positioned, and the inside of the refrigerating chamber 5 is formed so that the space divided up and down may be formed. The partitioned space communicates vertically with the gap between the pocket 14 of the door and the shelf 23. Each space formed by the shelf 23 and the branched cold air passages 19a and 19b communicate with each other, and a plurality of cold air discharge ports 24 through which cold air flows out toward the refrigerating chamber 5 are provided.

Ventilation duct 25 having a substantially cylindrical shape is supplied to the rear center portion of the refrigerating chamber 5 positioned between the plurality of cold air passages 19a and 19b, and cold air of the refrigerating chamber 5 is supplied to the ventilation duct 25. The refrigerating chamber fan 26 is arrange | positioned. The ventilation duct 25 is lengthened longitudinally, and the refrigerating chamber fan 26 is disposed below it, and they extend upward and downward in the central portion of the rear surface of the refrigerating chamber 5.

The refrigerating chamber fan 26 sucks cold air from the refrigerating chamber 5 from the refrigerating chamber cold air inlets 27 provided on both left and right sides thereof, and supplies the blown cold air to the ventilation duct 25. The ventilation duct 25 is hollow so that cold air flows inside, and a plurality of duct discharge ports 28 are formed in positions corresponding to the upper part of the space partitioned by the shelves 23 of the refrigerating chamber 5 up and down. The cool air supplied by the refrigerating chamber fan 26 is discharged from the duct discharge port 28 into the refrigerating chamber 5 as indicated by the arrow. The discharge speed of the cold air from the duct discharge port 28 is larger than the discharge speed of the cold air from the cold air discharge port 24 (preferably 3 times or more, most preferably about 10 times larger). The ventilation duct 25, the refrigerator compartment fan 26, and other structure are set. The cold air transferred to the space partitioned by each shelf 23 in the refrigerating compartment 5 flows in front of the refrigerating compartment 5, and passes through the front end of each shelf 23, as indicated by the arrow 23. And descend from the gap between the pockets 14. As shown by the arrow, the cooled cold air flows upward of the shelf surface on the upper surface of the ice-cold chamber 9 to the rear of the refrigerating chamber 5 and is sucked into the refrigerating chamber fan 26 from the suction port 27. In this way, the refrigerating chamber fan 26 and the ventilation duct 25 are means for circulating the cold air in the refrigerating chamber 5. The ventilation path of the refrigerating chamber 5 cold air by the refrigerating chamber fan 26 and the ventilation duct 25 is independent of the cooler 16 without passing through the cooler 16. In addition, the refrigerating chamber fan 26 is a centrifugal fan which sucks the cold air of the refrigerating chamber which flowed in from the inlet port 27 of the lower both sides of the rear surface of the refrigerating chamber 5 from the front surface, and blows it toward the upper ventilation duct 25.

The motor 29 which drives the ventilation duct 25 is arrange | positioned above the ventilation duct 25, and rotates the cylindrical ventilation duct 25 which extends up and down along the axis of an up-down direction. The direction of the duct discharge port 28 is changed by the rotation of the ventilation duct 25, and the direction of cold air discharged from the duct discharge port 28 to the refrigerating chamber 5 is adjusted.

The wind direction plate 30 provided in the ventilation duct 25 is formed to cross a passage in the ventilation duct 25 at a position corresponding to each duct outlet 28, for example, just above the duct outlet 28. A part of the cold air in the refrigerating chamber that has flowed inside the ventilation duct 25 from the lower side is changed in the refrigerating chamber 5 direction so as to easily flow out of the duct discharge port 28 at high speed.

The coolant discharged into the refrigerating chamber 5 from the discharge port 24 for blowing cold air supplied from the cooler chamber 18 and the duct discharge port 28 for blowing cold air sucked from the refrigerating chamber 5 is partially used for the refrigerating chamber as described above. Although the inside of the refrigerating chamber 5 is circulated through the fan 26 and the ventilation duct 25, some of the remaining cold air is formed below the refrigerating chamber 5 and communicates with the vegetable chamber 6 from the opening 31. Inflow). The cold air flowing into the vegetable compartment 6 flows upward of the container in the vegetable compartment 6 toward the front of the refrigerator, lowers the front part of the vessel, and then flows backward through the lower part of the container, and is not shown in the vegetable compartment 6. It returns to the cooler chamber 18 through the formed return opening and the cold air return passage.

In this way, the cool air in the refrigerator is cooled by the cooler 16 to the cooler chamber 18 through the refrigerating chamber 5 or the vegetable chamber 6 by the rotation of the cooler fan 17. The return circulation path and the cold air in the refrigerating compartment are sucked by the refrigerating compartment fan 26, flow out from the cold air outlet 28 to the refrigerating compartment 5 through the ventilation duct 25, and then flow back into the refrigerating compartment fan 26. It is equipped with the circulation path to make.

The refrigerator inner lamp 32 illuminating the inside of the refrigerating compartment 5 is disposed between the ventilation duct 25 and the adjacent cold air passages 19a and 19b, and the ventilation duct 25 and the cold air passages 19a and 19b are provided in the refrigerating compartment ( An invalid space between them generated when placed in the rear portion of 5) is effectively used. In addition, the cover 33 covering the refrigerator inner lamp 32 is disposed on the front surface of the refrigerator inner lamp 32, and at least a front portion of the refrigerator inner lamp 32 is formed of a member that transmits illumination light and diffuses the illumination light.

As mentioned above, the centrifugal fan 26 is arrange | positioned under the ventilation duct 25, and the inlet port 27 of cold air is formed in the left and right both sides of the refrigerating chamber fan 26. As shown in FIG. An inflow passage 35 is formed between the suction port 27 and the refrigerating chamber fan 26. In the inflow passage 35, a refrigerating chamber temperature sensor 36, which is a temperature detection means for detecting the temperature of the cold air flowing through the passage, is disposed. The temperature in the refrigerating chamber 5 is determined based on the temperature detected by the refrigerating chamber temperature sensor 36, and the flow control of the cold air by the damper flap 21 is performed. For example, when it is determined that the determined temperature is higher than the predetermined temperature and cooling of the refrigerating chamber 5 is necessary, the damper flap 21 is opened. In addition, when it is determined that the determined temperature is lower than the predetermined temperature and does not require cooling, the damper flap 21 is closed.

The ventilation duct 25 is assembled to the rear side of the rear panel 34 provided in the rear part of the refrigerating chamber 5. A cover 33 covering the panel 34 and the ventilation duct 25 is disposed on the front side of the rear panel 34. This cover 33 also serves as a lamp cover for covering the refrigerator inner lamp 32. The ventilation duct 25 is inclined forward in the refrigerating chamber 5, and the rear panel 34 and the cover 33 are also inclined in the refrigerating chamber 5 in the forward direction.

In addition, in order to detect the temperature of the storage space partitioned by each shelf 23 in the refrigerating chamber 5, the shelf 23 and the pocket (at each height position corresponding to the storage space of each shelf 23 are also provided. The direction determination sensor 37 which is a temperature detection means is arrange | positioned at the left and right wall surface located between 14). This direction determination sensor 37 detects the temperature of the cold air which flowed toward the front through the storage space partitioned by the shelf 23. When the cold air reaches the front end of the shelf 23, the cooler 14 cools the pocket 14 and descends downward through the space between the pockets 14 toward the lower side of the refrigerator, whereby the cold room circulation fan 26 disposed below. Toward the cold air suction port 27 and the opening 31 formed below the ice-cold chamber 9.

The direction determination sensor 37 detects the cold air temperature flowing through the storage space partitioned by the shelf 23. In the case where the stock is stored on the upper surface of the shelf 23, the flowing cold air exchanges heat with the stock and the temperature changes. Since the direction determination sensor 37 is arrange | positioned in multiple numbers up and down on the left and right both side wall surfaces which form the refrigerating chamber 5, it detects the temperature of the cold air which flows to the left and right both sides above each shelf 23, and compares the temperature of both sides. This detects which of the left and right cold air temperatures is high. When the detected higher temperature is higher than the set temperature of the refrigerating chamber 5, the direction of the cold air discharge port 28 of the ventilation duct 25 may be directed to a predetermined direction on the side where the detected temperature is higher. The ventilation duct 25 is rotated and stopped. And the cool air supplied to the ventilation duct 25 by rotation of the refrigerating chamber circulation fan 26 is taken out from the discharge port 28 toward the side where the detected temperature of the refrigerating chamber 5 is high.

Then, the plurality of cold air passages 19a and 19b including the cold air discharge ports 24 through which the cool air from the cooler 16 flows into the refrigerating chamber 5 are disposed therebetween, and the cold air in the refrigerating chamber 5 is sucked in. Since the refrigerator compartment fan 26 and the ventilation duct 25 which blow and supply between each shelf 23 in the refrigerator compartment 5 are provided, the cold and cold air discharge ports 24 circulated by the refrigerator compartment fan 26 are provided. Cooled cold air from each other can be matched with each other to equalize the temperature of the cold air in the refrigerating chamber 5. In particular, in the refrigerating chamber 5, the circulation which flows through each shelf 23, heat-exchanges a stock, heat-collects, the cold air of which temperature rose to the cold air suction port 27, and blows it again between the shelves 23 is performed. For this reason, it is possible to provide the storage with cold air at a temperature close to the temperature of the refrigerating chamber 5, and the storage can be cooled without excessively lowering the temperature of the storage.

Moreover, since the ventilation duct 25 which blows cold air in the refrigerating compartment 5 rotates so as to change the blowing direction, it collects after passing between each shelf 23 at the same time as the temperature from the cooler 16 is low cold. The cold air mixed with the cold air blown into the refrigerating chamber 5 is supplied to the storage. In addition, the cold air taking-out rate by the refrigerating chamber fan 26 is larger than the speed at which cold air from the cooler 16 flows out of the cold air discharge port 24 into the refrigerating chamber 5, and thus stored in addition to the above-described action. The movement of cold air in the refrigerating chamber 5, which has been impeded because water is loaded between the shelves 23, is promoted by the cold air leaked from the ventilation duct 25, thereby greatly exchanging heat exchange between the stored matter and the cold in the refrigerator. do. In addition, when the direction of the discharge port 28 of the cold air of the ventilation duct 25 is close to the left and right cold air discharge ports 24, the mixing of the cold air discharged from the cold air discharge port 24 and the circulating cold air in the refrigerating chamber is more preferable. By increasing, the above-mentioned action is further promoted.

In this way, since the mutual heat transfer is promoted by more actively contacting the cold and the stored matter in the refrigerator as compared to the refrigerator according to the prior art, the refrigerating chamber 5 due to the plural stores stored on the shelf 23 The deviation (temperature distribution) of the temperature in the inside becomes small, and the cooling efficiency in the refrigerator is improved.

In the case where the circulating air in the refrigerator is brought into contact with the storage material held at a lower temperature than the air inside the refrigerating chamber, the temperature can be raised in a shorter time than before. In particular, the one stored at a lower temperature than the air in the refrigerating chamber, such as meat and fish, can be set at the temperature in the refrigerating chamber in a short time, so that the thawing time is shortened.

In addition, if there is a discharge port 28 for circulation cold air in the refrigerating chamber of the ventilation duct 25 on the side close to the cold air discharge port 24 from the cooler 16, the air having a higher velocity blown out of the ventilation duct 25 Since the movement of the cold air in the vicinity of the cold air discharge port 24 from the cooler 16 is promoted, the cold air from the cold air discharge port 24 flows out smoothly from the discharge port 24, and the refrigerator compartment 5 is released from the cooler chamber 18. ) And the circulation efficiency of the cold air in the refrigerator circulated to the cooler chamber 18 through the vegetable chamber 6 is also improved.

A part of the cylindrical ventilation duct 25 is arrange | positioned in the dew receiving part 50 formed in the back part of the refrigerating chamber of the inner housing 3. By this structure, the dimension of protrusion to the refrigerator compartment side by arrange | positioning the ventilation duct 25 in the refrigerator compartment 5 becomes small, and the reduction of the storage volume in the refrigerator compartment 5 is reduced by its share. In other words, since the ventilation duct 25 can be enlarged, the quantity of circulating cold air in the refrigerator compartment 5 can be enlarged, and the uniformity of the temperature in the refrigerator compartment 5 and cooling efficiency can be made high. Moreover, the cover 33 can be comprised by a flat member, and productivity is favorable and it can be set as a good design.

In addition, the refrigerating chamber fan 26 is a centrifugal fan that sucks cold air from the front surface and blows it upwards, and does not need an axial flow path behind the fan like an axial fan, and therefore, the front and rear directions of the cold air flow path flowing to the fan. The space can be reduced, the space in the refrigerating chamber 5 can be effectively used, and the refrigerating chamber can be used with good ease of use.

Since the temperature in the refrigerator compartment 5 is detected by the refrigerator compartment temperature sensor 36 arrange | positioned in the inflow passage 35 of the cold air which flows into the refrigerator compartment fan 26 as mentioned above, each part of the refrigerator compartment 5, for example, Even if the temperature of the flowing cold air is at a different temperature, the cold air of each part is mixed when passing through the passage 35 or the heat of the cold air flowing through the passage 35 is heat-exchanged, so the temperature of the cold air in the passage 35 is more uniform. Getting closer to By detecting the temperature of such cold air, the influence of the cold air temperature entering from the outside due to opening and closing of the door 10 or the influence of the local temperature rise due to the storage loaded on the shelf 23 is reduced. The temperature of the refrigerating chamber 5 is detected with higher accuracy, so that the cooling efficiency of the refrigerating chamber 5 is improved, and further, the efficiency of the entire refrigerator is improved.

Next, the detailed structure of the ventilation duct part in the refrigerator which concerns on this invention is demonstrated using FIG. 4 is a view for explaining the structure of the ventilation duct portion of the refrigerator shown in FIG. FIG. 5 is a view for explaining a method of assembling the ventilation duct part shown in FIG. 4.

Moreover, above the ventilation duct 25, the motor 29 for rotating the ventilation duct 25 is connected via the link part 39. As shown in FIG. The motor 29 is preferably a stepping motor, so that the rotation position can be adjusted freely.

The communication member 38 is a member which supports the lower end of the ventilation duct 25 and guides the cold air blown out from the refrigerating chamber fan 26 to the ventilation duct 25. The ventilation duct 25 and the refrigerating chamber fan ( 26) is formed of a separate member or a different material. The communication member 38 is a member that connects the rotating ventilation duct 25 and the refrigerating chamber fan 26.

In this communication member 38, the dew receiving part 40 is formed concave downward at the side in which the ventilation duct 25 is inclined in the state connected to the refrigerating chamber fan 26, ie, the lower end part of the front part. The hole 41 is formed in the lower surface of this dew receiver 40. The dew receiver 40 is a dew receiver for storing water droplets formed by condensation of water contained in the cooling duct 25 into the water droplets or cold air circulated to the refrigerator compartment fan 26 inside the ventilation duct 25. The hole 41 is formed to drain the water stored in the dew receiver to the evaporation portion below. Since the ventilation duct 25 is inclined toward the front side of the refrigerator, water droplets attached to or entered into the ventilation duct 25 are likely to be stored at the lower end of the refrigerator front side when the ventilation duct 25 flows downward. The dew receiver 40 and the drain hole 41 are provided to efficiently collect and drain the water droplets.

As shown in Fig. 6, a plurality of projections 42 are formed in the outer peripheral portion of the cylinder at the lower end of the ventilation duct 25. As shown in Figs. Moreover, the bearing protrusion part 45 supported by the beam part 44 formed crosswise from the cylindrical part is formed in the lower end position corresponding to the cylindrical rotation axis of the ventilation duct 25. In addition, the communication member 38 has an opening formed in the upper portion thereof in accordance with the cylindrical shape of the ventilation duct 25, and the ventilation duct fitting portion 43 in which the lower end of the ventilation duct 25 is fitted inside is formed. It is. The protrusion 42 is formed so that the rotation shaft does not shake more than a certain level even when the rotation shaft is shaken when the ventilation duct 25 is inserted into the ventilation duct fitting portion 43 when an impact is applied to the ventilation duct 25. In the case where the cylindrical outer circumference of the ventilation duct 25 and the inner circumference of the fitting portion 43 slide in contact with each other, they are provided in order to reduce the contact area of both and reduce the resistance during rotation.

Moreover, the bearing dew receiving part 46 supported by the cross beam part 47 is formed in the substantially center part of this communication member 38. As shown in FIG. As the ventilation duct 25 is fitted into the ventilation duct fitting portion 43, the bearing dew receiving portion 46 and the bearing protrusion 45 are fitted to each other so that the bearing protrusion receiving portion is caused by the bearing dew receiving portion 46. 45 is bearing-supported, and shaft shake at the time of rotation of the said ventilation duct 25 is suppressed. Thereby, the rotation of the ventilation duct 25 becomes smoother.

The lower end of the ventilation duct 25 is formed with a cross-shaped beam portion 44 for supporting the bearing protrusion 45, the duct fitting portion 43 of the cross-shaped support for the bearing dew receiving portion 46 A beam 47 is formed. The cold air blown out from the refrigerating chamber fan 26 passes through the space around the beams 44 and 47 and flows into the ventilation duct 25.

Fig. 7 shows an example in which the ventilation duct 25 is formed from two parts 25a and 25b divided approximately two times in the vertical direction, and the ventilation duct 25 is considered in consideration of ease of assembly and reduction of manufacturing cost. It is produced by dividing into two.

As mentioned above, the rotating ventilation duct 25 and the refrigerating chamber fan 26 which is a rotating member communicate with the communicating member 38 which is a separate member. The communication member 38 is provided with a dew receiver 40 having a hole 41 for draining water at the lower end of the front portion, and is positioned above the dew receiver 40 and is inclined forward. The water dripping from the front lower end part of the duct 25 is stored, water is drained from the water drain hole 41, and it is suppressed that moisture in the ventilation duct enters the fan. In particular, since the ventilation duct 25 is inclined toward the front side of the refrigerator, moisture tends to collect at the lower end portion of the front side of the ventilation duct 25 so that moisture is efficiently collected and drained. Thereby, the occurrence of an accident such as a failure due to the ingress of moisture in the refrigerating compartment fan 26 can be prevented.

In addition, the communication member 38 can be formed of a material which is more excellent in wear resistance and impact durability than the ventilation duct 25. As such, it can be combined with the ventilation duct 25 formed of a lighter and lower cost material.

And since the rotary motor 29 for rotating the ventilation duct 25 is arrange | positioned above the ventilation duct, it is suppressed that the water droplet inside the ventilation duct 25 enters the motor 29, and can suppress a failure occurrence. have.

In addition, the opening area of the cold air discharge port 28 formed in the ventilation duct 25 is smaller as the upper opening is shown in FIG. This is because the cold air flowing inside the ventilation duct 25 is easy to be stored above the ventilation duct 25, so in the same opening area, most of the cold air flows out of the upper opening 23 and flows out above the upper shelf 23. The amount of cold air flowing out between the lower shelves 23 becomes smaller than the amount of cold air. On the other hand, the upper shelf 23 usually has a high height, and the storage tends to be stacked on the lower shelf 23. For this reason, when the opening area of the discharge port 28 of the ventilation duct 25 is made the same, most cold air is supplied to the upper shelf with few stored things, and less cold air is supplied to the lower shelf with many stored things. The overall efficiency of cooling the stored product is lowered.

In order to solve such a problem, the opening area of the discharge port 28 is comprised so that the opening of the discharge port corresponding to the upper shelf may be made smaller than the opening area corresponding to the lower shelf, and the ventilation duct 25 to the shelf is opened. The amount of cold air supplied to the oven is adjusted to provide as much cold air as possible between each shelf as evenly as possible between the shelves.

Moreover, the wind direction plate 30 is formed in the ventilation duct 25 for making the direction of the cold air which flows inside the ventilation duct 25 transversely from the upper direction to the refrigerator compartment 5 side as mentioned above. The cold air in the refrigerating chamber, which has blown up the inside of the ventilation duct 25 from the refrigerating chamber fan 26 downward, touches the wind direction plate 30 and easily changes direction in the refrigerating chamber 5 direction. It is easy to flow out of).

In addition, as disclosed by the indicator portion 48 shown by the oblique line in Fig. 7, the ventilation duct 25 is attached to a color different from that of the inner wall surface of the panel 34 or the refrigerating chamber 5 so as to rotate the ventilation duct. However, the direction of rotation can be clearly defined so that the user can clearly see it.

Next, with reference to FIG. 8, the detection method of the rotation angle position of the ventilation duct in the refrigerator of this invention is demonstrated. FIG. 8 is a view for explaining a method for detecting a rotation angle position of a ventilation duct in the refrigerator shown in FIG.

In FIG. 8, the link part 39 is joined to the ventilation duct 25 by connecting the rotation shaft of the rotary motor 29 and the ventilation duct 25. In FIG. The positioning unit 49 is for positioning the rotating link unit 39 and the ventilation duct 25, and serves as a screw seat for fixing the rotary motor 29 to the rear panel 34.

Positioning of the rotation position of the ventilation duct 25 is performed as follows.

In advance, the angle range at which the cooling air is blown by rotating the ventilation duct 25 is set (90 ° in this embodiment). At this time, the positioning part 49 is set so that the rotation angle range of the link part 39 may become larger than the rotation angle range of this ventilation duct 25 (96 degrees in this embodiment).

Next, the rotary motor 29 is driven to rotate the ventilation duct 25 in one direction until the link portion 39 contacts the positioning portion 49. Based on this contact position, the rotary motor 29 is driven in the opposite direction, and the ventilation duct 25 is rotated in another direction until the link portion 39 comes into contact with the positioning portion 49 on the opposite side. The rotatable angle of the part 39 is detected. Further, the rotary motor 29 is driven in the opposite direction, rotated to an angle of 1/2 of the rotatable angle of the link portion 39, and stopped, and the position is set to 0 °. The rotational drive is performed at an angle range of 90 ° in which the ventilation duct 25 is discharged in one direction and the other direction with this 0 ° as the rotation center.

For this reason, the link part 39 does not contact the positioning part 49 during the normal rotational drive of the ventilation duct 25.

As described above, the rotation drive angle smaller than the rotatable angle range of the ventilation duct 25 is set in advance, and the ventilation duct 25 is rotated to the limit of the rotation angle once, and the reference of the rotation drive angle is thereafter from this position. Set the location. At that time, the reference position is set so that the limit position of the rotational drive angle is not the limit position of the rotatable angle. In this way, the link portion 39 does not come into contact with the positioning portion 49 during the rotational drive of the ventilation duct 25, and thus the link portion 39 repeatedly contacts the positioning portion 49. Problems such as fatigue breakage of the link portion and abnormal sounds at the contact of both can be reduced.

Next, the assembling method of the ventilation duct, the refrigerator compartment fan, etc. in the refrigerator which concerns on this invention is demonstrated using FIGS. Fig. 9 is a cross sectional view of the refrigerator compartment top of the refrigerator according to the present invention. FIG. 10 is a cross-sectional view of a lower portion of the refrigerator compartment of the refrigerator illustrated in FIG. 9. FIG. 11 is a perspective view illustrating a method of assembling the rear panel and the ventilation duct of the refrigerator shown in FIG. 9.

As shown in FIG. 11, the ventilation duct 25, the communication member 38, and the refrigerating compartment fan 26 are mounted and coupled to the panel 34 from the rear side of the refrigerating compartment rear panel 34. As shown in FIG. In the state in which they are assembled to the panel 34 and integrated, the panel 34 is assembled to the rear part of the refrigerating chamber 5 together with the ventilation duct 25 and the refrigerating chamber fan 26, and is located on the rear side of the refrigerating chamber 5. Construct the wall. In addition, as shown in Fig. 2, a cover 33 is disposed on the front side of the rear panel 34. The cover 33 is arranged to cover the front face of the refrigerator inner lamp 32 and the front face of the rear panel 34 disposed between the cold air passages 19a and 19b and the ventilation duct 25, but in the present embodiment In this case, after the rear panel 34 is assembled inside the refrigerator 1, the rear panel 34 is connected to the rear panel. The cover 33 may have a structure as assembled in the refrigerator 1 after joining with the back panel 34.

As shown in FIG. 9, the dew receiver 50 is formed in the back part of the inner housing 3 in the position which opposes the cylindrical ventilation duct 25, and this dew receiver is assembled with the back panel 34 assembled. A part of the ventilation duct 25 is accommodated in the part 50. Thereby, the ventilation duct 25 does not protrude more than necessary on the refrigerator compartment side, and the fall of the storage volume of the refrigerator compartment 5 by arrange | positioning the ventilation duct 25 on the back side of the refrigerator compartment 5 is reduced or prevented.

As shown in Fig. 10, a passage 35 of cold air flowing into the refrigerating chamber fan 26 is formed, and inlets 27 through which cold air in the refrigerating chamber flows into the passage 35 are formed on both sides. Cool air in the refrigerating chamber flows into the refrigerating chamber fan 26 from the inlets 27 on the left and right sides of the refrigerating chamber fan 26, and then flows into the refrigerating chamber fan 26 located behind the passage 35.

1, the board | substrate 51 which mounted electric components etc. is arrange | positioned at the upper back side of the refrigerator main body 1 located in the upper back of the refrigerating chamber 5, as shown in FIG. Since the substrate 51 generates heat during operation of the refrigerator, it is necessary to reduce the heat from the substrate 51 entering the refrigerating chamber 5. To this end, the dew receiver 50 is provided in the inner housing 3 in accordance with the position of the ventilation duct 25, and the dew receiver 50 and the ventilation duct 25 when the ventilation duct 25 is assembled. There is a gap between the two. The influence of the heat from the substrate 51 to the ventilation duct 25 is reduced by the cold air in the refrigerator compartment 5 in this gap, and cold air blows from the ventilation duct 25 to the refrigerator compartment 5, and the refrigerator compartment Since the movement of cold air in the inside is promoted, the influence of heat from the substrate 51 behind the cold air passages 19a and 19b to the refrigerating chamber 5 is also reduced. For this reason, it is not necessary to provide a swelling part inside the refrigerating chamber 5, and the indoor storage volume can be reduced and it can be made easy to use.

Next, the structure of the cold air | gas outlet part in the refrigerator which concerns on this invention is demonstrated using FIG. 12 thru | or FIG. 12 is a longitudinal sectional view showing the structure of part A of FIG. FIG. 13 is a longitudinal sectional view showing the structure of part B of FIG. 14 is a longitudinal sectional view showing the structure of a cold air outlet portion of a conventional refrigerator.

12 and 13, the heat insulating material 52 forming the cold air discharge port 24 and the cold air passages 19a and 19b through which cold air flows from the cold air passages 19a and 19b to the refrigerating chamber 5; A rear panel 34 and a cover 33 coupled thereto are illustrated, and passages of cold air reaching the cold air discharge ports 24 from the cold air passages 19a and 19b include the heat insulating material 52, the back panel 34, and the cover ( It is shown that 33 are connected to each other.

As shown in FIG. 12, the top discharge port 24 of the back panel 34 is formed with the inclined slit part 53 fitted in the opening provided inclined by the heat insulating material 52, and the cold air flow direction may be inclined upwards. It is inclined. In addition, the cold air discharge port 24 of the cover 33 is formed with the horizontal slit part 54 formed in conformity with the front surface of the inclined slit part 53 of the back panel 34. As shown in FIG.

By such a configuration, the flow of cold air in the passages 19a and 19b from below to the top can be stably supplied into the refrigerating chamber 5. In particular, the effect is large in the A portion of the cold air discharge port 24 between the upper shelves having a large flow rate as shown in FIG.

As shown in FIG. 13, in the lower part of the cold air discharge port 24, the cylindrical passage opening part 56 of the back panel 34 is provided so that it may communicate with the opening part 55 provided horizontally in the heat insulating material 52, The cylindrical passage opening portion 58 of the cover 33 is formed to communicate with the passage opening portion 56. These openings 56 and 58 form a cold air discharge port 24.

In addition, in the conventional configuration of the conventional cold air passage, as shown in FIG. 14, the cold air discharge port 24 is formed only by the rear panel 34, so that the cold air flow is not stable and the cold air flow between the stored products is not smooth. Did.

As described above, in the present embodiment, the refrigerating chamber fan 26 and the ventilation duct 25 are assembled to the panel 34 from the rear of the panel 34, and are integrally assembled to the rear side of the refrigerating chamber 5 so that the manufacturing process is performed. It can be simplified to lower the manufacturing cost.

Next, with reference to FIGS. 15-17, the sensor attachment in the refrigerator which concerns on this invention is demonstrated. Fig. 15 is a longitudinal sectional view showing an example of the arrangement of the direction determination sensor of the refrigerator according to the present invention. 16 is a longitudinal sectional view showing another example of the arrangement of the direction determination sensors of the refrigerator according to the present invention. 17 is a cross sectional view showing an attachment structure of a direction determination sensor of a refrigerator according to the present invention.

In Fig. 15, the direction determination sensor 37 is located in front of the front end of the shelf 23 and also in the pocket 14 of the door 10 in correspondence with the height position of the space partitioned by each shelf 23. It is arrange | positioned in multiple numbers up and down on the inner wall surface of the left and right both sides of the refrigerating chamber 5 in the back. By arranging the direction determination sensor 37 in this way, the temperature of the cold air which has changed in temperature can be detected more accurately by coming into contact with the storage loaded on the shelf after flowing out from the discharge ports 24 and 28 of the rear part of the refrigerating chamber 5. have.

In Fig. 16, the direction determination sensor 37 is located behind the pocket 14, but is disposed on the inner wall surfaces of the left and right sides of the refrigerating chamber 5 slightly behind the front end of the shelf 23. It is different from that of FIG. By doing in this way, the influence on the temperature detection of the direction determination sensor 37 by the entry of the outside air at the time of opening and closing of the door 10 can be reduced, and the temperature change of the cold air in the refrigerating chamber 5 can be detected more accurately.

In Fig. 17, Fig. 17A is an example of the attachment structure of the direction determination sensor. In this attachment structure, the sensor part 59 and the sensor cover 60 covering the same are sandwiched in the heat insulating member 61 and are configured not to protrude from the inner housing 3 to the inside of the refrigerating chamber. The direction determination sensor 37 is divided into the upper member 62 and the lower member 63. The upper member 62 has a sensor portion 59 and a sensor cover 60. In addition, the lower member 63 is provided to form a dew receiving portion in the heat insulating material 61, and is attached to the heat insulating material side of the inner housing 3. The inner housing 3 has an opening formed at a position corresponding to the dew receiving portion of the lower member 63, and the upper member 62 is fitted to each of the sensor portion 59 and the cover 60 in this opening.

Fig. 17B is another example of the attachment structure of the direction determination sensor 37. Figs. In this example, the direction determination sensor 37 is composed of the upper member 62 and the lower member 63, which is the same as that shown in Fig. 17A, but the sensor portion 59 and the cover 60 It is different in that it is formed so that it may protrude to the refrigerator compartment side.

In one embodiment of the refrigerator according to the present invention described above, since the cooler fan 17 is cooled by the cold chiller cooled by the cooler 16, the refrigerator compartment 5 can be reliably cooled. And a wind direction changing means 26 for changing the discharge direction of the cold air to the refrigerating chamber 5 and the refrigerating chamber fan 26 which circulates the cold air of the refrigerating chamber 5 independently of the cooler 16. In this way, it is possible to intensively cool down newly stored high-temperature foods and the like in a short time without excessively cooling the already stored foods and the like, and to change the discharge direction of cold air in the refrigerating chamber The temperature distribution in the refrigerating chamber 5 can be uniformized in a short time.

In addition, since the cool air from the refrigerating chamber fan 26 is discharged to the refrigerating chamber 5 at a speed faster than the discharge rate of the low temperature cold air cooled by the cooler 16 to the refrigerating chamber 5, the newly stored high temperature food and the like are further reduced. Cooling can be performed in a shorter time, and cold air can be spread to every corner of the refrigerating chamber 5, and the temperature distribution in the refrigerating chamber 5 can be further averaged.

In addition, the newly stored hot food is discharged by discharging the cold air from the refrigerating chamber fan 26 to the refrigerating chamber 5 at a speed three times or more faster than the discharge speed of the low temperature cold air cooled by the cooler 16 to the refrigerating chamber 5. The shortening of the cooling time, etc., and the shortening of the temperature equalization time of the temperature in the refrigerating chamber 5 can be made remarkable.

In addition, since the refrigerating compartment temperature sensor 36 is provided near the suction part of the refrigerating compartment fan 26 to control the operation of the refrigeration cycle based on the detected temperature of the refrigerating compartment temperature sensor, it is cooled by the cooler 16. The refrigerator compartment temperature sensor 36 can detect the temperature of the refrigerator compartment cold air in the state where the chilled air and the refrigerator compartment 5 are mixed, and thus the refrigerator compartment representative temperature can be reliably detected even when the refrigerator compartment temperature partially rises due to door opening and closing. This makes it possible to reliably control the refrigeration cycle.

Then, a plurality of cold air discharge ports 24 for discharging the cold air from the cooler 16 are formed on both sides of the rear surface of the refrigerating chamber 5 up and down, and the discharge outlets for circulation for discharging the cold air from the wind direction changing means 26 ( Since a plurality of 28 are formed in the center of the rear surface of the refrigerating chamber 5 up and down, the portions near the walls on the left and right sides of the refrigerating chamber 5 are likely to increase in temperature by cooling with the cold from the cooler 16 over the upper and lower sides. While maintaining the averaging of the temperature distribution in the left and right directions and the up and down directions in (5), the temperature distribution in the left and right directions and the up and down directions can be further averaged by the cold from the wind direction changing means 26 in the central part of the refrigerating chamber 5, The temperature distribution of the whole inside the refrigerator compartment 5 can be averaged further.

In addition, since the plurality of cold air discharge ports 24 and the plurality of circulation discharge ports 28 are formed to communicate with each of the spaces divided up and down by the plurality of shelves arranged in the refrigerating chamber 5, In the case where hot food or the like is newly stored in the space, the cold air from the wind direction changing means 26 can be reliably ventilated toward the hot food or the like from the circulating discharge port 28 communicating with the space, and the hot food and the like are Can be cooled more reliably.

In addition, since the rear panel and the wind direction changing means 26 are inclined forward, the cold air easily touches the food stored in each shelf of the refrigerating chamber 5, and the cooling time of the stored food can be further shortened.

Since the centrifugal fan is used as the refrigerating chamber fan 26, the cold air from the plurality of circulating discharge ports 28 passes through a ventilation path extending from the refrigerating chamber centrifugal fan 26 to the discharge side and extending up and down. Can be discharged at high speed, whereby cooling in the case of newly storing hot food or the like can be performed in a shorter time.

In addition, the cover 33 is disposed at an interval in front of the refrigerating chamber centrifugal fan 26, and a closed surface portion is formed in the cover 33 portion located in front of the suction part of the centrifugal fan 26, and the closing is performed. Since the cold air suction port 27 is formed around the surface portion, it is possible to prevent food or the like from directly entering the suction part of the cold compartment centrifugal fan 26 while ensuring the cold air suction passage to the cold compartment centrifugal fan 26. Can be.

In addition, since the airflow direction changing means 26 which changes the discharge direction by rotating the discharge port of the cold air in the refrigerating chamber 5 circulated by the refrigerating chamber fan 26, the discharge direction can be changed in a simple and inexpensive configuration, Cooling can be concentrated in a short time by directing the discharged cold air into a hot food or the like newly stored in (5), and the discharge direction of the cold air can be changed to uniformize the temperature in the refrigerating chamber in a short time.

Further, the ventilation duct 25 having a discharge port 28 for guiding the cold air of the refrigerating chamber 5 ventilated from the refrigerating chamber fan 26 and discharging it to the refrigerating chamber 5 is rotatable to change the discharge direction of the discharge port. Since it supports, the guide of cold air and the change of discharge direction are comprised by the very simple structure which doubled the ventilation duct 25 itself, and it can be made cheap and compact.

Since the discharge port of the refrigerating chamber fan 26 and the suction port of the cylindrical ventilation duct 25 are connected to the cylindrical communication member 38 which rotatably supports the ventilation duct 25, the ventilation duct ( While supporting 25 rotatably, cold air can be reliably supplied to the cylindrical ventilation duct 25 from the refrigerating chamber fan 26.

In addition, the pivot support mechanism is pivotally supported between the beam portion 44 of the ventilation duct 25 and the beam portion 47 of the communication member 38 by the bearing protrusion 45 and the bearing dew receiving portion 46. By this, the center of rotation of the ventilation duct 25 can be reliably aligned, and the communication part of the ventilation duct 25 and the communication member 38 can be made compact, without impairing the ventilation of cold air.

And since the dew receiving part 40 is provided in the communication member 38 located below the cylindrical ventilation duct 25 which extends up and down in the refrigerator compartment back part so that the cold air of the refrigerator compartment 5 may be guided, the ventilation duct ( Dew generated in 25 can be received by the dew receiving portion 40 of the communication member 38, thereby preventing the dew from flowing into the refrigerating chamber fan 26.

In addition, since the dew receiving portion 40 of the communicating member 38 is integrally formed with the communicating member 38 and has a guide portion to the dew evaporation portion, the dew generated in the ventilation duct 25 is treated with a very simple configuration. can do.

Since the opening area of the uppermost discharge port of the ventilation duct 25 is formed smaller than the lower end, the plurality of discharge ports 2 are formed without concentrating the cold air discharged from the ventilation duct 25 to the uppermost discharge port 28 in a simple configuration. Can be discharged on average.

Moreover, since the duct drive motor 29 is arrange | positioned above the ventilation duct 25 which guides the cooling air of the ventilation duct 25 upward, the cold air of the refrigerator compartment 5 which circulates with respect to the duct drive motor 29 is carried out. The influence can be made small, and dew attachment of the duct drive motor 29 can be easily prevented.

In addition, since the ventilation duct 25 is set to rotate at a narrower angle by using a positioning unit that regulates the rotation angle of the stepping motor 29 that rotates the ventilation duct 25, the stepping motor 29 operates at each positioning unit. High reliability can be achieved without contact.

Moreover, since the dew receiving part 50 is provided in the refrigerator main body 1 corresponding to the cylindrical ventilation duct 25, and the said ventilation duct 25 is partially accommodated in this dew receiving part 50, Deterioration of the heat insulation function of the main body 1 can be suppressed, and the storage volume of the refrigerator compartment 5 can be ensured.

Moreover, in the Example of this invention, it is the outstanding refrigerator which has these functions simultaneously.

According to the present invention, it is possible to reliably cool the refrigerating chamber with a cold chiller cooled by a cooler, and to refrigerate a newly stored high temperature food or the like without excessively cooling foods that have already been stored and are being reduced to the storage compartment temperature. It is possible to obtain a refrigerator which can be cooled in a cold manner in a short time, and can be cooled in a short time, and in which the temperature distribution in the refrigerating chamber can be uniformized.
