Japanese Patent Laid-Open No. 2001-66051 (page 2 to page 6, FIG. 2)

  However, according to the conventional refrigerator, the cold air discharged from the discharge port does not reach the end of the refrigerator compartment when the refrigerator compartment is widened. For this reason, there has been a problem that the temperature distribution in the refrigerator compartment becomes non-uniform. If the width of the cold air passage is formed wide in order to allow the cold air to reach the end of the refrigerator compartment, the flow area of the cold air passage is widened, so the flow rate of the cold air is reduced. Thereby, the cold air flowing into the cold air passage from below does not reach the upper portion of the cold air passage. As a result, there is a problem that the temperature distribution in the refrigerator compartment becomes non-uniform similarly to the above.

  An object of this invention is to provide the refrigerator which can make uniform temperature distribution of the storage chamber with a large volume.

  In order to achieve the above object, the present invention provides a storage chamber for storing stored items, a cooler for generating cold air flowing into the storage chamber, and a cooler disposed on the back surface of the storage chamber for receiving the cool air from the cooler. A cold air passage that circulates, a member that extends around the cold air passage to cover the front side of the cold air passage, transmits cold heat of the cold air that flows through the cold air passage, and discharges it into the storage chamber; A heat insulating member disposed in the cold air passage and a discharge port for discharging the cold air flowing through the cold air passage to the storage chamber are provided.

  According to this configuration, the cold air generated by the cooler flows through the cold air passage and is discharged from the discharge port, and flows through the storage chamber to cool the stored item. The cold heat of the cold air flowing through the cold air passage is conducted through the member and discharged into the storage chamber from a wide area on the back surface of the storage chamber. At this time, the cold heat of the cool air immediately after flowing into the cool air passage on the back of the storage chamber is insulated by the heat insulating member.

  Further, the present invention is characterized in that in the refrigerator configured as described above, the member is detachable.

  Moreover, the present invention is characterized in that, in the refrigerator having the above-described configuration, the discharge port is disposed at a side end portion of the cold air passage. According to this configuration, the discharge port and the side wall of the storage chamber are arranged close to each other.

  According to the present invention, in the refrigerator configured as described above, the member is disposed on a front surface of a duct made of a resin molded product forming the cold air passage, and the discharge port is opened on a side wall of the duct. It is characterized by covering. According to this configuration, the cold air discharged into the storage chamber from the discharge port opened in the side wall of the duct diffuses on the back side of the end portion of the member and circulates in the storage chamber.

  Moreover, the present invention is characterized in that in the refrigerator configured as described above, cold air flowing through the cold air passage is in direct contact with at least a part of the member.

  Further, the present invention provides the refrigerator having the above-described configuration, wherein the cold air passage has a first and a second branch passage that branches from side to side in the lower part and extends in the vertical direction and is connected by a connection part in the upper part, and is generated by the cooler. It is characterized in that the cooled cold air flows into the cold air passage from below. According to this configuration, the cold air flowing into the cold air passage from below the storage chamber is branched into the first and second branch passages, rises, and is discharged into the storage chamber. Some of the cool air flows from one of the first and second branch paths to the other through the upper connecting portion.

  Moreover, the present invention is characterized in that, in the refrigerator having the above-described configuration, the discharge port is provided in the connecting portion. According to this structure, cold air is discharged from the substantially upper center of the storage chamber.

  Further, in the refrigerator having the above-described configuration, another storage room is disposed below the storage room via a heat insulating wall, and the blower for sending the cold air to the cold air passage and the heat insulating wall overlap with each other in a front projection. It is characterized by the arrangement. According to this structure, the cold air | gas produced | generated with the cooler distribute | arranged below the storage room flows in into a cold air | gas channel | path by the drive of an air blower.

  Moreover, the present invention is characterized in that in the refrigerator configured as described above, a concave portion or a convex portion for collecting condensed water is provided on the surface of the member. According to this configuration, the condensed water generated on the surface of the member flows down and is held on the inner surface of the concave portion or the upper surface of the convex portion. The condensed water held in the recesses or protrusions is then evaporated and the storage chamber is moisturized.

  Moreover, the present invention is characterized in that, in the refrigerator having the above-described configuration, the discharge port is formed on a peripheral surface of the concave portion or the convex portion. According to this structure, the cold air discharged from the discharge port opened on the inner peripheral surface of the concave portion or the outer peripheral surface of the convex portion flows along the member.

  According to the present invention, the member that discharges the cold heat of the cold air flowing through the cold air passage at the back of the storage chamber is provided to extend around the cold air passage, so that the flow passage area of the cold air passage is maintained at a required size and formed. The member can release cold heat from a wider range to the storage chamber. Thereby, the remarkable fall of the flow rate of cold air is suppressed, cold air reaches the inside of the cold air passage, and cold heat reaches the entire storage room. Therefore, the temperature distribution in the storage chamber having a large volume can be made uniform.

  In addition, since the member is arranged on the back surface away from the opening of the storage chamber, even if outside air flows in from the opening, the temperature is lowered until the member reaches the member, and condensation generated on the member can be reduced. Furthermore, since the cold heat immediately after flowing into the cold air passage is thermally insulated by the heat insulating member, dew condensation generated on the back surface of the storage chamber can be reduced.

  Further, according to the present invention, since the member is made detachable, the member can be easily cleaned to keep the storage chamber clean.

  According to the present invention, since the discharge port is arranged at the side end of the cold air passage, the side end of the storage chamber can be further cooled to make the temperature distribution in the storage chamber more uniform.

  Further, according to the present invention, since the discharge port is formed by opening on the side wall of the duct forming the cool air passage, and the outside of the side wall of the duct is covered by the member, the cool air discharged into the storage chamber diffuses along the member. Circulate. Therefore, the amount of cold heat transmitted to the member increases, and the temperature distribution in the storage chamber can be made more uniform.

  According to the present invention, since the cold air flowing through the cold air passage is in direct contact with at least a part of the member, the amount of cold heat transmitted to the member can be further increased.

  According to the present invention, since the cold air passage is branched into the first and second branch passages at the lower portion, the cold air can be discharged to the end of the storage chamber without increasing the flow passage area of the cold air passage. Moreover, since the upper part of the 1st, 2nd branch path is connected by a connection part, even if a difference arises in the quantity of cold air branched to the 1st, 2nd branch path, it equalizes via a connection part. Accordingly, it is possible to make the temperature distribution uniform by making the amount of cool air discharged into the storage chamber substantially the same on the left and right.

  According to the present invention, since the discharge port is provided in the connecting portion, the cold air is discharged from the substantially upper center of the storage chamber. Therefore, cold air is discharged to the end and center of the storage chamber, and the temperature distribution in the storage chamber can be made more uniform.

  Moreover, according to this invention, since the heat insulation wall and the air blower were arrange | positioned in the position which overlaps in a front projection below the storage chamber, a storage chamber and an air blower are arrange | positioned closely. For this reason, even if the volume of a store room is large, the difference in the intensity | strength of the cold airflow discharged between the discharge outlet close | similar to a fan and a distant discharge opening becomes small. Therefore, the temperature distribution in the storage chamber can be made more uniform. Moreover, since the blower is not arranged in the storage chamber, it is possible to secure a large volume in the storage chamber and improve the volumetric efficiency of the refrigerator.

  Further, according to the present invention, since the concave portion or the convex portion for accumulating the dew condensation water is provided on the surface of the member extending around the cold air passage, the dew condensation water can be held in a wide range. Therefore, the moisturizing effect in the storage chamber due to evaporation of condensed water can be improved.

  According to the present invention, since the discharge port is formed on the peripheral surface of the concave portion or the convex portion, the cold air discharged from the discharge port flows along the member. Therefore, the amount of cold heat transmitted to the member increases, and the temperature distribution in the storage chamber can be made more uniform.

  Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a front view and a right side view showing the refrigerator of the first embodiment. The refrigerator 1 is provided with a refrigerator compartment 2 (storage compartment) that is opened and closed by a door 2a. Below the refrigerator compartment 2, a temperature switching chamber 3 and an ice making chamber 4 that are opened and closed by doors 3a and 4a are arranged side by side. Below the temperature switching chamber 3 and the ice making chamber 4, a freezing room 6 that is opened and closed by a door 6 a is arranged, and below the freezing room 6 is a vegetable room 5 that is opened and closed by a door 5 a.

  The refrigerator compartment 2 stores stored items in a refrigerator, and the vegetable compartment 5 cools and preserves vegetables at a room temperature (about 8 ° C.) higher than the refrigerator compartment 2. As will be described later in detail, the temperature switching chamber 3 can be switched by the user at room temperature. The freezer 6 stores the stored items in a frozen state, and the ice making chamber 4 communicates with the freezer 6 to make ice. The ice making room 4 and the freezing room 6 are maintained below the freezing point, and the ice making room 4 constitutes a part of the freezing room 6 in this specification.

  3 and 4 are a right side cross-sectional view and a front view of the refrigerator 1. The main body of the refrigerator 1 is filled with a foam heat insulating material 1c between the outer box 1a and the inner box 1b. The ice making chamber 4 and the temperature switching chamber 3 are separated from the refrigerator compartment 2 by a heat insulating wall 7, and the freezer compartment 6 and the vegetable compartment 5 are separated from each other by a heat insulating wall 8. Further, the temperature switching chamber 3 and the freezing chamber 6 are isolated by a heat insulating wall 35, and the temperature switching chamber 3 and the ice making chamber 4 are isolated by a vertical heat insulating wall 36.

  The foam heat insulating material 1c is made of urethane foam heat insulating material or the like, and is filled in the heat insulating walls 7 and 8 simultaneously when filled between the outer box 1a and the inner box 1b. That is, the stock solution of the foam heat insulating material 1c is injected simultaneously between the outer box 1a and the inner box 1b and into the heat insulating walls 7 and 8 communicating with the outer box 1a, and is foamed integrally. Thereby, the heat insulation walls 7 and 8 can be easily formed thinly. Therefore, the volume of the refrigerator compartment 2 can be ensured widely.

  The exterior of the heat insulating walls 7 and 8 is made of a separate member from the inner box 1b. Before filling the foam heat insulating material 1c, the side surfaces of the heat insulating walls 7 and 8 are opened and the inner box 1b is formed on the side surfaces of the heat insulating walls 7 and 8. Open oppositely. By filling the foam heat insulating material 1c, the openings on the side surfaces of the heat insulating walls 7 and 8 and the opening of the inner box 1b are connected and integrated.

  Thereby, the leakage of cold air or warm air between the storage chambers separated by the heat insulating walls 7 and 8 in different temperature zones is prevented. Therefore, it is possible to save energy by reducing heat loss. Moreover, the abnormal noise which generate | occur | produces by the vibration of the heat insulation walls 7 and 8 and the sliding of the heat insulation walls 7 and 8 and the inner case 1b by this vibration can be prevented. In addition, the structural strength by the integral formation can be improved.

  The ice making room 4, the freezing room 6, the vegetable room 5 and the temperature switching room 3 are provided with a storage case 43 for storing stored items. The refrigerator compartment 2 is provided with a plurality of storage shelves 41 on which stored items are placed. A plurality of storage pockets 42 are provided on the door 2 a of the refrigerator compartment 2. Thereby, the usability of the refrigerator 1 is improved.

  In addition, a chilled chamber 21 including an isolation chamber whose upper surface is partitioned and separated by a partition plate 41a is provided at a lower portion in the refrigerator compartment 2. The chilled chamber 21 is maintained in a temperature range different from that of the refrigerator compartment 2, for example, a chilled temperature range (about 0 ° C.). The chilled chamber 21 is provided with a storage case 107 for storing stored items. Instead of the chilled chamber 21, an ice greenhouse maintained at an ice temperature (about −3 ° C.) may be used.

  A machine room 50 is provided behind the vegetable room 5, and a compressor 57 is disposed in the machine room 50. The compressor 57 is connected to a condenser, an expander (not shown), and a cooler 11, and a refrigerant such as isobutane is circulated by driving the compressor 57 to operate a refrigeration cycle. Thereby, the cooler 11 becomes the low temperature side of the refrigeration cycle.

  An electrical component 51 is provided at the rear of the machine room 50. The electrical component 51 has an electrical component box 52 that is attached to the main body of the refrigerator 1 and has an open rear side. The electrical component 51 is sealed by a rear cover 50 a that closes the rear surface of the machine room 50. The electrical box 52 is formed by drawing a metal plate, has a large heat radiation area, can easily dissipate heat generated by the electrical components, and can easily seal the interior of the electrical component 51.

  The electrical component 51 includes electrical components including a control board 53 having a control circuit for controlling the compressor 57 and each blower. Since the electrical unit 51 is installed in the machine room 50, the volume of the refrigerator room 2, which is frequently used, is increased as compared with the case where it is installed behind the refrigerator room 2, and the volume efficiency of the refrigerator 1 is improved. Can be improved.

  Behind the freezer compartment 6 is provided a cold air passage 31 partitioned by a back plate 6b. Behind the refrigerator compartment 2 is provided a cold air passage 32 communicating with the cold air passage 31 via the refrigerator compartment damper 20. The cool air passage 31 is partitioned into a front part 31a and a rear part 31b by a partition plate 31c, and the cooler 11 is arranged in the rear part 31b. Since the cooler 11 is arranged on the back side of the freezer compartment 6, the cold heat of the cooler 11 is released to the freezer compartment 6 side through the partition plate 31c, the front part 31a, and the back plate 6b. For this reason, the freezer compartment 6 is indirectly cooled efficiently, and the cooling efficiency is improved.

  The cooler 11 on the low temperature side of the refrigeration cycle exchanges heat with the air flowing through the cold air passage 31 to generate cold air. A defrost heater 33 for defrosting the cooler 11 is provided below the cooler 11. Below the defrost heater 33, a soup saucer 63 for receiving water by defrost is provided. The soy saucer 63 is provided with a drain pipe 64, and drain water is guided to an evaporating dish (not shown) disposed in the machine room 50 via the drain pipe 64.

  In the cold air passages 31 and 32, the freezer compartment fan 12 and the refrigerator compartment fan 23 are respectively arranged. As will be described in detail later, the cold air generated by the cooler 11 flows through the front portion 31 a of the cold air passage 31 by driving the freezer compartment fan 12, and is supplied to the freezer compartment 6, the ice making chamber 4, and the temperature switching chamber 3. . The cold air is supplied to the refrigerator compartment 2, the chilled compartment 21 and the vegetable compartment 5 through the cold passage 32 by driving the refrigerator compartment fan 23.

  The freezer compartment fan 12 is composed of an axial fan, and is disposed with the exhaust side facing forward and upward. Thereby, the cold air cooled by the lower cooler 11 can be efficiently sucked from the diagonally rear side of the freezer compartment fan 12. Further, the cool air is sent forward and upward toward the front portion 31 a of the cool air passage 31, discharged to the ice making chamber 4, and led to the upper cool air passage 32. Accordingly, it is possible to efficiently distribute the cool air upward to reduce noise and save energy.

  The refrigerating room blower 23 is composed of an axial fan, and is arranged with the axial direction directed up and down. Thereby, similarly to the above, it is possible to efficiently distribute the cool air upward to reduce noise and save energy. Moreover, the refrigerator compartment fan 23 becomes low in a height direction, and the refrigerator compartment fan 23 and the heat insulation wall 7 can be arrange | positioned in the same horizontal surface so that it may overlap in a front projection.

  Thereby, the refrigerator air blower 23 is not arrange | positioned behind the refrigerator compartment 2 with a high usage frequency, and the depth of the cold air | gas channel | path 32 can be narrowed. That is, the depth of the cold air passage 32 is formed to 80 mm, for example, on the discharge side of the refrigerator fan 23, and is gradually narrowed toward the downstream side of the air flow, for example, 12 mm. At this time, the total width in the left-right direction of the cold air passage 32 is formed wider than the vicinity of the discharge side of the refrigerator compartment fan 23. Thereby, the ventilation area of the cool air passage 32 is ensured, the cool air flow rate is maintained, and the reduction of the blowing efficiency is prevented. Therefore, the depth of the refrigerator compartment 2 in front of the narrowed cold air passage 32 is increased, and the volume of the refrigerator compartment 2 can be secured widely.

  In addition, the heat insulation wall 7 may be provided above the figure to maintain the volume of the refrigerator compartment 2, and the volume of the temperature switching chamber 3 and the ice making chamber 4 may be secured widely. Moreover, you may form the refrigerator compartment fan 23 with a centrifugal fan. At this time, the centrifugal fan may be arranged with the suction side facing downward and the discharge side facing left and right, so that the air flow is directed upward during or after air discharge.

  In addition, since the refrigerating room blower 23 is provided in a region that overlaps the heat insulating wall 7 in the vertical direction, the freezing room blower 12 is disposed at a low position away from the ice making tray 62 disposed above the ice making room 4. However, since the discharge direction of the cold air from the freezer blower 12 is the direction of the ice tray 62 at the upper front, the water stored in the ice tray 62 can be efficiently cooled.

  The front side of the cold air passage 32 is covered with the panel assembly 120. In the panel assembly 120, a panel 100 made of a resin molded product is arranged on the front surface of a duct 102 made of a foamed resin molded product, and a member 101 having high thermal conductivity is arranged on the front side thereof. For the duct 102, a foamed resin such as foamed polystyrene having high heat insulation is used. The panel 100 is made of a resin such as PP, PS, or ABS that can be easily processed. The member 101 is made of metal such as aluminum or stainless steel having high corrosion resistance.

  The duct 102 has a heat insulating portion 102d that covers and heat-insulates a substantially entire lower portion facing the chilled chamber 21 with a predetermined thickness. As a result, the cool air passage 32 is provided with a heat insulating member on the side where the cool air flows from the cooler 11. The low temperature cold air immediately after flowing into the cold air passage 32 from the cooler 11 is thermally insulated by the heat insulating portion 102d. For this reason, the dew condensation which generate | occur | produces on the back surface of the chilled room 21 distribute | arranged in the refrigerator compartment 2 can be reduced.

  An illumination lamp 110 covered with a lamp cover 109 is disposed on the ceiling surface of the refrigerator compartment 2. The light emitted from the illumination lamp 110 illuminates the inside of the refrigerator compartment 2 from above, and reflects off the surface of the member 101 to illuminate the inside of the refrigerator compartment 2 from behind. Thereby, the inside of the refrigerator compartment 2 can be made brighter. It is more desirable that the lamp cover 109 and the storage shelf 41 are made of translucent or transparent glass or resin (ABS, PS, polycarbonate, acrylic, etc.).

  FIG. 4 shows a front sectional view of the refrigerator 1. The member 101 is detachably provided on the upper portion of the panel 100 by an engaging claw 100a projecting from the panel 100 and an attachment member 101a. Therefore, the member 101 can be easily cleaned and the inside of the refrigerator compartment 2 can be kept clean.

  The duct 102 is attached to the panel 100 by an engaging claw (not shown) protruding from the panel 100. Thereby, the duct 102, the panel 100, and the member 101 are integrated. The panel assembly 120 is attached to the inner box 1b by an engaging claw (not shown) provided on the back side peripheral portion of the panel 100. As the attachment member 101a, a screw or a resin-made push pin with a pointed arrow shape is used.

  The panel 100 and the duct 102 may be divided into upper and lower parts with the lower end of the member 101 as a boundary, and the member 101, the upper part of the panel 100, and the upper part of the duct 102 may be assembled to be detachable as described above. .

  The cold air passage 32 is formed with first and second branch passages 32 a and 32 b branched at the lower portion by the duct 102. The first and second branch paths 32a and 32b are connected to each other at the upper portion of the refrigerator compartment 2 by a connecting portion 32c. Discharge ports 103 a and 103 b for discharging cool air to the chilled chamber 21 are provided in the lower portion of the cool air passage 32 so as to open to the panel 100.

  Discharge ports 105a and 105b for discharging cold air to the refrigerator compartment 2 are provided at the upper ends of the first and second branch paths 32a and 32b, respectively, so as to open to the member 101. The connecting portion 32 c is provided with a discharge port 105 c that discharges cool air in the upper part of the center of the refrigerator compartment 2 so as to open to the member 101.

  FIG. 5 is a cross-sectional view taken along the line AA of FIG. 4 and shows a cross section of the second branch path 32b. The first branch path 32a and the second branch path 32b are formed symmetrically. The duct 102 has protrusions 102a and 102b protruding rearward, and the protrusions 102a and 102b abut against the inner box 1b to form the second branch path 32b.

  The inner protrusion 102b is formed in an annular shape, and forms a space 111 between the first and second branch paths 32a and 32b. The outer protruding portion 102a forms the side walls of the first and second branch paths 32a and 32b and is opened at a predetermined interval to be provided with discharge ports 104a (see FIG. 4) and 104b. The cold air flowing through the first and second branch paths 32a and 32b is discharged from the discharge ports 104a and 104b toward the side wall of the refrigerator compartment 2. Since the discharge ports 104a and 104b are arranged at the side end of the cold air passage 32, the inside of the refrigerator compartment 2 can be easily cooled to the side end. The inner box 1b has an inclined surface 1d that is inclined forwardly outside the protrusion 102a.

  The front surface side of the duct 102, the panel 100, and the member 101 are arranged outside the protrusion 102 a and are formed to extend around the cool air passage 32. An opening 102e is formed in the duct 102 so as to face the first and second branch paths 32a and 32b. The panel 100 is provided with a concave portion 100b that faces the first and second branch paths 32a and 32b and has a small thickness.

  The cold heat of the cold air flowing through the cold air passage 32 is transmitted to the member 101 via the recess 100 b and is released into the refrigerator compartment 2 via the member 101. Thereby, the temperature distribution of the refrigerator compartment 2 is equalized. The cold air flowing through the cold air passage 32 by opening the recess 100 b may be in direct contact with the member 101.

  Further, the recess 100b may be formed to extend to the front side of the space 111. Thereby, a part of the cool air in the cool air passage 32b flows into the front of the space 111 through the recess 100b, and the cool heat is released from the central portion of the member 101. Thereby, cold heat can be more uniformly released from the member 101. At this time, a discharge port may be provided on the front surface of the space 111 to discharge cool air from the center of the member 101.

  If the cold air has a lot of cold heat, the concave portion 100b may be omitted and the front side of the opening 102e may be shielded by the duct 102 to adjust the heat insulation thickness.

  FIG. 6 shows a side sectional view of the member 101. A concave portion 113 and a convex portion 112 extending horizontally are formed on the surface of the member 101. The inner surface of the concave portion 113 and the upper surface of the convex portion 112 face upward, and accumulates condensed water generated in the member 101. Condensed water is generated when outside air having a high temperature flows into the refrigerator compartment 2 when the door 2a is opened, etc., and contacts the low temperature member 101. When the door 101 is closed and the inside of the refrigerator compartment 2 is cooled, the condensed water held by the member 101 gradually evaporates. Thereby, the moisturizing effect of the refrigerator compartment 2 can be acquired.

  In addition, since the member 101 having high thermal conductivity is disposed only on the back surface away from the opening of the refrigerator compartment 2, even if outside air flows from the opening, the temperature is lowered until the member 101 is reached. Therefore, condensation occurring on the member 101 can be reduced.

  A discharge port 114 (such as a discharge port 105a or a discharge port on the front surface of the space 111) formed on the surface of the member 101 is formed to be open on the inner peripheral surface of the recess 113 or the outer peripheral surface of the protrusion 112. The cold air discharged from the discharge port 114 flows along the surface of the member 101, and the amount of cold heat transmitted to the member 101 increases, so that the temperature distribution in the refrigerator compartment 2 can be made more uniform. The discharge port 114 is supplied with cold air via a passage (not shown) that penetrates the duct 102 and the panel 100. Thereby, the discharge port 114 can be formed in the whole area | region of the back surface of the refrigerator compartment 2, and cold air can be discharged.

  The concave portion 113 and the convex portion 112 on the member surface may have other shapes. For example, as shown in the top sectional view of FIG. 7, the discharge port 114 is formed on the inner peripheral surface of the side surface of the recess 113 formed in the member 101. Moreover, as shown in the front view of FIG. 8, the mark 115 which consists of a character and a pattern may protrude from the member surface. As shown in FIG. 9, which is a cross-sectional view taken along the line B-B in FIG. At this time, the temperature distribution in the refrigerator compartment 2 can be adjusted by setting the discharge direction of the discharge port 114 to a desired direction such as a vertical direction or a horizontal direction.

  In FIG. 4, a tank 108 for automatic ice making separated from the chilled chamber 21 and a partition wall (not shown) is arranged in the refrigerator compartment 2. Water in the tank 108 passes through a pipe (not shown) by a pump (not shown) and is supplied to an ice tray 62 of an ice making device 108a provided in the ice making chamber 4 below. Thereby, water is automatically supplied to the ice tray 62, and ice is automatically made.

  The refrigerator compartment fan 23, the refrigerator compartment damper 20, and the freezer compartment fan 12 are arranged substantially side by side in the vertical direction. That is, the refrigerating room blower 23, the refrigerating room damper 20, and the freezing room blower 12 are arranged so as to overlap in the planar projection. Thereby, while the width | variety of the left-right direction of the refrigerator 1 can be narrowed, the cool air passages 31 and 32 can be shortened and volume efficiency and ventilation efficiency can be improved more.

  The cold air passage 31 behind the freezer compartment 6 opens the front of the freezer compartment fan 12, and air is sent out to the ice making chamber 4 by the freezer compartment fan 12. A freezer compartment return port 22 is provided at the lower part of the freezer compartment 6 communicating with the ice making chamber 4. Further, an introduction ventilation path 15 that branches from the cold air passage 31 and guides the cold air to the temperature switching chamber 3 is provided.

  The upper part of the cold air passage 31 communicates with the cold air passage 32 via the refrigerator compartment damper 20. When the refrigerator compartment damper 20 is opened and the freezer compartment fan 12 is driven, cold air is supplied to the refrigerator compartment 2 and the chilled compartment 21. The refrigerator compartment damper 20 is arranged behind the vertical heat insulation wall 36 so as to overlap the vertical heat insulation wall 36 in front projection.

  In order to secure a large volume of the temperature switching chamber 3, the vertical heat insulating wall 36 that separates the temperature switching chamber 3 and the ice making chamber 4 is arranged to be biased to the right side in the drawing. The cold air passage 32 branches from the outlet side of the cold room damper 20 to the left and right so that the cold air is discharged from the entire cold room 2. At this time, if the refrigerator compartment damper 20 is arranged in the center in the left-right direction, the cold air can be evenly circulated through the cold air passage 32 branched to the left and right.

  However, if the front portion 31 a (see FIG. 3) of the cold air passage 31 and the baffle of the refrigerator compartment damper 20 are provided behind the temperature switching chamber 3, heat is released from the temperature switching chamber 3 into the cold air passage 31. Cold air flowing through the cold air passage 31 is generated at, for example, -23 ° C. For this reason, when the temperature switching chamber 3 is controlled to a temperature higher than the cold air (for example, 3 ° C., 8 ° C., or 50 ° C.), heat loss increases.

  Therefore, the baffle of the refrigerator compartment damper 20 and the front part 31a (see FIG. 3) of the cold air passage 31 are provided behind the vertical heat insulating wall 36 to prevent heat from being released from the temperature switching chamber 3 to the cold air passage 31. As a result, the refrigerator compartment damper 20 can be brought closer to the center in the left-right direction, and the cooling efficiency can be further improved.

  The refrigerator compartment outlet 2b is opened at the lower back of the refrigerator compartment 2, and the vegetable compartment inlet 5b is provided in the vegetable compartment 5. The refrigerator compartment outlet 2b and the vegetable compartment inlet 5b are connected by a connecting path 34 that passes through the back surface of the temperature switching chamber 3 so that the refrigerator compartment 2 and the vegetable compartment 5 communicate with each other. A return ventilation path 46 (see FIG. 3) communicating with the cold air passage 31 is provided at the upper back of the vegetable compartment 5.

  A temperature switching chamber blower 18 and a heater 16 are disposed on the upper portion of the temperature switching chamber 3. A temperature switching chamber discharge damper 37 is provided at the lower right of the temperature switching chamber 3. The temperature switching chamber discharge damper 37 is disposed on the introduction ventilation path 15, and the temperature switching chamber blower 18 is disposed above the introduction ventilation path 15. When the temperature switching chamber discharge damper 37 is opened and the temperature switching chamber blower 18 is driven, cold air flows from the cooler 11 into the temperature switching chamber 3 through the introduction ventilation path 15. The amount of air flowing into the temperature switching chamber 3 from the introduction ventilation path 15 is adjusted by the opening / closing amount of the temperature switching chamber discharge damper 37.

  A temperature switching chamber return damper 38 is provided at the lower left portion of the temperature switching chamber 3. The temperature switching chamber return damper 38 opens and closes the return ventilation path 17 extending downward, and the air in the temperature switching chamber 3 returns to the cool air passage 31 via the return ventilation path 17.

  The cooler 11 is formed by meandering refrigerant pipes 11a through which refrigerant flows, and left and right ends of the refrigerant pipes 11a are supported by end plates 11b. A large number of fins (not shown) for heat dissipation are provided in contact with the refrigerant pipe 11a.

  The air flowing from the temperature switching chamber 3 through the return ventilation path 17 is returned to the cooler 11 through an outlet 17 a provided in the middle of the cooler 11 in the vertical direction. The cold air flowing out from the freezer compartment 6 through the freezer return port 22 returns to the lower part of the cooler 11, and the cold air flowing out from the vegetable compartment 5 and passing through the return passage 46 returns to the lower part of the cooler 11.

  Therefore, the cold air flowing out from each storage chamber is returned to the cooler 11 in a dispersed manner. For this reason, the frost by the cold air containing the water | moisture content which circulated through each store room and returned does not generate | occur | produce intensively, but disperse | distributes and generate | occur | produces to the cooler 11 whole. Thereby, clogging of the cold air flow due to frost is prevented, and a decrease in cooling performance of the cooler 11 can be prevented.

  In addition, the cold air that has flowed through the temperature switching chamber 3 with a small volume is cooled at the upper part of the cooler 11, and the cold air that has flowed through the large-sized refrigerating chamber 3, the vegetable room 5, and the freezer room 6 Cooled by. Therefore, the cold air flowing out from the temperature switching chamber 3 is not heat exchanged with the cooler 11 more than necessary, and the heat exchange efficiency of the cooler 11 can be improved.

  Further, the cold air flowing out from the freezer compartment 6 through the freezer return port 22 is guided between the end plates 11b on both sides. The cold air flowing out from the vegetable compartment 5 is guided to the entire left and right direction inside and outside the end plates 11b on both sides of the cooler 11 via a return ventilation path 46 (see FIG. 3).

  Thereby, the heat exchange area of the cold air flowing out from the vegetable compartment 5 becomes larger than the heat exchange area of the cold air flowing out from the freezer compartment 6. Therefore, the low temperature cold air returning from the freezer compartment 6 is not cooled more than necessary, and the high temperature cold air returning from the vegetable compartment 5 is cooled by the entire cooler 11 so that the heat exchange efficiency of the cooler 11 can be further improved.

  Since the temperature switching chamber 3 may be maintained at the freezing temperature, the end plate 11b is provided with a notch (not shown) at a position facing the outlet 17a of the return ventilation path 17. Thereby, the cold air that has flowed out of the temperature switching chamber 3 can be guided between the end plates 11b on both sides to disperse the cold air. Therefore, the condensation of the cooler 11 can be dispersed and clogging can be further prevented.

  A gas-liquid separator 45 is connected to the upper part of the refrigerant pipe 11a. The gas-liquid separator 45 is arranged at the end of the ice making chamber 4 away from the temperature switching chamber 3. Thereby, even if the temperature switching chamber discharge damper 37 is disposed below the temperature switching chamber 3, it does not interfere with the gas-liquid separator 45. As a result, it is possible to avoid the interference between the refrigerator compartment damper 20 and the temperature switching chamber discharge damper 37 and arrange the refrigerator compartment damper 20 behind the vertical heat insulating wall 36.

  FIG. 10 is a cold air circuit diagram showing the flow of cold air in the refrigerator 1. The freezer compartment 6, the refrigerator compartment 2, and the temperature switching chamber 3 are each arranged in parallel. The ice making room 4 is arranged in series with the freezer room 6, and the vegetable room 5 is arranged in series with the refrigerator room 2. The cold air generated by the cooler 11 is sent to the ice making chamber 4 by driving the freezer blower 12. The cold air sent to the ice making room 4 flows through the ice making room 4 and the freezing room 6, flows out from the freezing room return port 22, and returns to the cooler 11. As a result, the ice making chamber 4 and the freezing chamber 6 are cooled.

  The cold air branched off on the exhaust side of the freezer compartment fan 12 is sent to the suction side of the refrigerator compartment fan 23 via the refrigerator compartment damper 20 by driving the refrigerator compartment fan 23. The cold air sent out from the cold room blower 23 flows in the cold air passage 32 while being squeezed in the front-rear direction and spreading left and right. As a result, the cool air suddenly lowers the flow rate, converts the dynamic pressure into static pressure, and flows upward. The ventilation efficiency can be improved by reducing the flow rate of the cold air.

  A part of the cold air flowing through the cold air passage 32 is discharged into the chilled chamber 21 from discharge ports 103a and 103b provided in the lower part. The cold air discharged from the discharge ports 103a and 103b flows into the case 107 in the chilled chamber 21. Since the cold air flowing into the cold air passage 32 is immediately supplied to the chilled chamber 21, the stored item in the case 107 is cooled to a temperature lower than that of the refrigerator compartment 2.

  The remaining cold air flowing through the cold air passage 32 moves up the first and second branch passages 32a and 32b branched to the left and right, and is discharged from the discharge ports 104a and 104b to the refrigerator compartment 2. Further, cool air is discharged into the refrigerator compartment from the discharge ports 105a to 105c provided in the upper portions of the first and second branch paths 32a and 32b and the connecting portion 32c. Further, the cold heat of the cold air flowing through the cold air passage 32 is transmitted to the member 101 extending around the cold air passage 32. Thereby, even if the refrigerator compartment 2 is large, cold heat is discharged | emitted from the wide range of the refrigerator compartment 2 back surface, and the temperature distribution of the refrigerator compartment 2 is equalized.

  Since the connecting portion 32c is provided, even if there is a difference in the amount of cold air branched into the first and second branch paths 32a and 32b, it is made uniform through the connecting portion 32c. Therefore, it is possible to make the temperature distribution uniform by making the amount of cold air discharged into the refrigerator compartment 2 substantially the same on the left and right. Moreover, since the discharge port 105c is provided in the connection part 32c, cold air is discharged from the substantially center upper part of the refrigerator compartment 2. FIG. Accordingly, cold air is discharged from the discharge ports 104a, 104b, 105a, and 105b to the end of the refrigerator compartment 2, and cold air is discharged from the discharge port 105c to the central portion. Therefore, the temperature distribution in the refrigerator compartment 2 can be made more uniform.

  The cool air discharged from the discharge ports 104a and 104b along the inner box 1b flows obliquely forward on the inclined surface 1d, and is diffused in the vertical direction by the member 101 extending around the cool air passage 32. As a result, cold air uniformly flows into the refrigerator compartment 2 while diffusing from the entire outer periphery of the member 101. Further, the member 101 is further cooled by the cold air flowing out over the entire outer periphery of the member 101, and the amount of cold heat released from the member 101 can be increased.

  The cold air discharged into the refrigerator compartment 2 circulates forward on the storage shelf 41 and the partition plate 41a, and exchanges heat with the stored items placed thereon. And the stored item in the storage pocket 42 provided in the door 2a is cooled and flows downward. The cold air flowing downward flows between the side wall of the refrigerating chamber 2 on the side of the refrigerating chamber outlet 2 b and the outside of the case 107 and flows into the connecting path 34 from the refrigerating chamber outlet 2 b.

  The cold air flowing through the connection path 34 flows into the vegetable compartment 5. The cold air flowing into the vegetable compartment 5 circulates in the vegetable compartment 5 and returns to the cooler 11 through the return ventilation path 46. Thereby, the inside of the refrigerator compartment 2 and the vegetable compartment 5 is cooled, and when it becomes preset temperature, the refrigerator compartment damper 20 will be closed.

  Further, the cold air branched on the exhaust side of the freezer compartment fan 12 flows into the temperature switching chamber 3 through the temperature switching chamber discharge damper 37 by driving the temperature switching chamber blower 18. The cold air that has flowed into the temperature switching chamber 3 flows through the temperature switching chamber 3, flows out of the temperature switching chamber return damper 38, and returns to the cooler 11 through the return ventilation path 17. Thereby, the inside of the temperature switching chamber 3 is cooled.

  As described above, the temperature switching chamber 3 can switch the room temperature by a user's operation. The operation modes of the temperature switching chamber 3 are wine (8 ° C.), refrigeration (3 ° C.), chilled (0 ° C.), soft freezing (−8 ° C.), and freezing (−15 ° C.) depending on the temperature zone. Provided.

  Thus, the user can store the refrigerated product at a desired temperature by refrigeration or refrigeration. The room temperature can be switched by varying the amount of opening of the temperature switching chamber discharge damper 37. For example, the heater 16 may be energized to switch the temperature from the refrigerated room temperature to the refrigerated room temperature. Thereby, it can switch to desired room temperature rapidly.

  Further, by energizing the heater 16, the room temperature of the temperature switching chamber 3 can be switched from a low temperature side where the stored items are cooled and stored to a high temperature side higher than normal temperature. Thereby, temporary heat insulation, warm cooking, etc. of the cooked heated food can be performed.

  According to the present embodiment, the member 101 that releases the cold heat of the cold air flowing through the cold air passage 32 on the back of the refrigerator compartment 2 is provided extending around the cold air passage 32, so that the flow passage area of the cold air passage 32 has a required size. It is possible to release the cold heat from a wider range to the refrigerating chamber 2 by the member 101. Thereby, the remarkable fall of the flow velocity of cold air is suppressed, cold air reaches the inside of the cold air passage 32, and cold heat reaches the entire refrigerator compartment 2. Therefore, even if the volume of the refrigerator compartment 2 is increased, the temperature distribution can be made uniform. The member 101 is formed to extend to the side of the cold air passage 32, but may be formed to extend vertically.

  Furthermore, since the member 101 also covers the front surface of the space 111 between the first and second branch paths 32a and 32b, it is possible to release the cold heat of cold air over a wider range. Therefore, the temperature distribution in the refrigerator compartment 2 can be made more uniform and the moisturizing effect can be improved. In addition, since the area where the illumination lamp 110 reflects the light increases, the inside of the refrigerator compartment 2 can be brightened in a wider range.

  Further, since the member 101 is disposed on the back surface away from the opening of the refrigerator compartment 2, dew condensation generated on the member 101 can be reduced. Furthermore, since the holding area of the dew condensation water can be widened, the dew condensation water flowing into the refrigerator compartment 2 can be reduced. In addition, since the cold heat of the low temperature cold air immediately after flowing into the cold air passage 32 is thermally insulated by the heat insulating portion 102d, dew condensation occurring on the back surface of the chilled chamber 21 in the refrigerator compartment 2 can be reduced.

  In addition, since the cold air passage 32 is branched into the first and second branch passages 32a and 32b by the space 111, the refrigerator 1 becomes large and the flow area of the cold air passage 32 can be appropriately increased even if the left and right widths are widened. Can keep. Thereby, the cold air from the refrigerator compartment fan 23 can be sufficiently sent to the upper part of the refrigerator compartment 2. Further, cold air can be sent to the end of the refrigerator 2.

  Moreover, since the heat insulation wall 7 under the refrigerator compartment 2 and the refrigerator compartment fan 23 were arrange | positioned in the position which overlaps in front projection, the refrigerator compartment 2 and the refrigerator compartment fan 23 are arrange | positioned closely. For this reason, even if the volume of the refrigerator compartment 2 is large, the difference of the strength of the cold airflow discharged between the outlet near the refrigerator fan 23 and the outlet far from the refrigerator 23 becomes small.

  Therefore, the temperature distribution in the refrigerator compartment 2 can be made more uniform. Moreover, since the refrigerator compartment fan 23 is not arrange | positioned in the refrigerator compartment 2, the volume of the refrigerator compartment 2 can be ensured widely, and the volumetric efficiency of the refrigerator 1 can be improved. In addition, the volume of the other storage chambers, such as the temperature switching chamber 3, may be ensured by maintaining the volume of the refrigerator compartment 2.

  Next, FIG. 11 is a front sectional view showing the refrigerator of the second embodiment. For convenience of explanation, the same reference numerals are assigned to the same parts as those in the first embodiment shown in FIGS. In the present embodiment, the cold air passage 32 on the back surface of the refrigerator compartment 2 extends upward without branching, and extends to the left and right at the top. Other parts are the same as those in the first embodiment.

  A protrusion 102a protruding from the rear surface of the duct 102 forms a cold air passage 32 at the center. The protrusions 102 a are provided in an annular shape on both sides of the cold air passage 32 to form a space 111. The cool air passage 32 extends left and right above the space 111, and discharge ports 104a and 104b are formed at the left and right ends.

  The member 101 covers the outer side of the side wall of the duct 102 and extends around the cool air passage 32. Thereby, similarly to 1st Embodiment, the flow-path area of the cold air | gas channel | path 32 can be formed small, and cold heat can be discharge | released to the refrigerator compartment 2 from the wide range by the member 101. FIG. Thereby, the remarkable fall of the flow velocity of cold air is suppressed, cold air reaches the inside of the cold air passage 32, and cold heat reaches the entire refrigerator compartment 2. Therefore, even if the volume of the refrigerator compartment 2 is increased, the temperature distribution can be made uniform.

  Since the discharge ports 104a and 104b are provided in the upper part of the refrigerator compartment 2, the cold air discharged from the discharge ports 104a and 104b flows down by its own weight. Thereby, cold air can be spread in the refrigerator compartment 2.

  Next, FIG. 12 is a side sectional view showing the refrigerator of the third embodiment. For convenience of explanation, the same reference numerals are assigned to the same parts as those in the first embodiment shown in FIGS. In this embodiment, the refrigerating room blower 23 is disposed so that the exhaust side is inclined rearward and upward. Other parts are the same as those in the first embodiment.

  According to this embodiment, the same effect as that of the first embodiment can be obtained. In addition, the cold air generated by the cooler 11 is guided to the front portion 31 a of the cold air passage 31 by the freezer blower 12, and is led to the intake side of the refrigerating room blower 23 through the refrigerating room damper 20. The cold air passage 32 is disposed above the cold room blower 23 and behind the cold room damper 20.

  For this reason, the cool air is smoothly guided from the front portion 31 a to the cool air passage 32 by the refrigerator compartment fan 23. Therefore, the vortex of the cold airflow is not easily generated, and the pressure loss is also reduced, so that the blowing efficiency can be improved to save energy and the generation of noise can be suppressed.

  Next, FIG. 13, FIG. 14 is the front view and right side sectional drawing which show the refrigerator of 4th Embodiment. For convenience of explanation, the same reference numerals are assigned to the same parts as those in the first embodiment shown in FIGS. In the present embodiment, the refrigerator compartment fan 23 (see FIG. 3) is omitted from the first embodiment, and the arrangement of the refrigerator compartment fan 12 and the refrigerator compartment damper 20 is different. Other parts are the same as those in the first embodiment.

  The freezer compartment blower 12 is disposed at the right end of the refrigerator 1 main body, and partially overlaps the heat insulating wall 7 in front projection, and the lower portion extends to the freezer compartment 6 side. Thereby, the cool air passage 31 has a long distance between the cooler 11 and the freezer compartment fan 12 and can take a wide space. For this reason, this space part functions as a negative pressure chamber on the suction side of the freezer compartment blower 12, and in the vicinity of the upper portion of the cooler 11, the cold airflow is substantially uniform in the front-rear direction and the left-right direction. As a result, the cool air that exchanges heat with the cooler 11 circulates uniformly in the front-rear direction and the left-right direction, and the heat exchange efficiency of the cooler 11 is improved.

  Moreover, the freezer compartment fan 12 is arrange | positioned behind the ice-making tray 62 distribute | arranged to the ice-making chamber 4 upper part, and blows it toward the ice-making tray 62 of the front. For this reason, the ice tray 62 can be sufficiently cooled, and the ice making can be completed quickly. Depending on the positional relationship between the freezer blower 12 and the ice tray 62, the freezer blower 12 may be disposed toward the ice tray 62. For example, the freezer compartment fan 12 may be disposed obliquely upward or obliquely downward, or may be disposed slightly inclined in the left-right direction.

  Moreover, you may arrange | position the freezer compartment fan 12 so that the discharge direction of cold air may face a little from the center of the left-right direction. Thereby, the ventilation efficiency to the refrigerator 20 for refrigerator compartments and the temperature switching chamber discharge damper 37 improves.

  The refrigerator compartment damper 20 is adjacent to the left side of the freezer compartment fan 12 and is disposed so as to overlap the heat insulating wall 7 in front projection. Accordingly, the depth of the ice making chamber 4 can be secured widely to improve the volumetric efficiency, and the space below the refrigerator compartment damper 20 can be secured widely to easily increase the distance between the cooler 11 and the freezer compartment fan 12. Can do. It should be noted that the refrigerator compartment damper 20 may be provided close to the heat insulating wall 7 in the vertical direction.

  According to this embodiment, the same effect as that of the first embodiment can be obtained. Moreover, since the heat insulation wall 7 below the refrigerator compartment 2 and the freezer compartment fan 12 are arranged at the overlapping position in the front projection, the refrigerator compartment 2 and the freezer compartment fan 12 are arranged close to each other. For this reason, even if the volume of the refrigerator compartment 2 is large, the difference of the strength of the cold airflow discharged between the discharge port close to the freezer blower 12 and the distant discharge port becomes small.

  Therefore, the temperature distribution in the refrigerator compartment 2 can be made more uniform. Moreover, since the freezer compartment fan 12 is not arranged in the refrigerator compartment 2, the volume of the refrigerator compartment 2 can be secured widely and the volume efficiency of the refrigerator 1 can be improved.

  In the first to fourth embodiments, a damper may be provided at the outlet of the vegetable compartment 5. Thereby, when the temperature switching chamber 3 is switched from the high temperature side to the low temperature side, it is possible to prevent the hot air from the temperature switching chamber 3 from flowing backward into the vegetable chamber 5 by closing the damper. In addition, when the freezer compartment fan 12 is stopped when the temperature switching chamber 3 is switched from the high temperature side to the low temperature side, a passage opening / closing mechanism (for example, a damper) is provided so that the freezer compartment return port 22 is closed. Also good. Thereby, it is possible to prevent the hot air from flowing backward from the freezer return port 22 into the freezer compartment 6 by driving the temperature switching chamber blower 18.

  According to this invention, it can utilize for the refrigerator provided with the member which discharge | releases cold heat in a storage room.
