Description

  The present invention relates to a refrigerator outlet structure for a refrigerator that is provided in front of a fan in which cooling air cooled by a refrigerator is blown out in a refrigerator having a refrigerator and a fan.

  Conventionally, as a commercial refrigerator-freezer used for freezing and refrigeration of food, etc., a cooler, a fan, and a food shelf are installed in a cabinet surrounded by a heat-insulating box, and cooled by blowing from the fan A food freezer is known in which food placed on a food shelf is frozen by cooling air that circulates in the cabinet through a container (see Patent Document 1). In such a refrigerator-freezer, an outlet structure is provided in front of the fan from which cooling air is blown. In the refrigerator-freezer described in Patent Document 1, a distribution duct that evenly distributes the cooling air blown from the fan to the food shelf is provided on the front surface of the fan as such an outlet structure. The distribution duct includes a rectangular frame that surrounds the front of the fan, and horizontal partition plates that are provided in multiple stages in the frame according to the food shelves.

JP 2000-356462 A (page 3-5, Fig. 1-2)

  According to the refrigerator-freezer described in Patent Document 1, the cooling air cooled by the cooler and blown out from the fan passes through the distribution duct which is the outlet structure for the refrigerator-freezer provided on the front surface of the fan. And this cooling wind is induced | guided | derived so that it may blow off horizontally by the ventilation path divided by the partition plate provided in multiple stages horizontally in the frame body, The blowing direction to the horizontal direction is a fixed direction with a wind direction guide plate. Will be aligned. However, in the refrigerator outlet structure described in Patent Document 1, the cooling air can be blown out only in the horizontal direction. And since the cooling air blown out from the blower outlet structure has a density larger than the average density of the air in the refrigerator-freezer, it moves downward immediately after being blown out due to the influence of gravity. For this reason, in the refrigerator / freezer, it becomes easy for the cold air to stay in the lower space, the temperature easily varies with the upper space, and there is a problem that uniform cooling in the refrigerator / refrigerator is difficult. .

  In a refrigerator, since frost is generated and adheres to the cooler and the fan during operation, the front side of the outlet structure or the outlet structure is closed inside the outlet structure (on the fan side). A defrosting operation for melting the frost attached to the cooler and the fan is performed by operating the heater and confining the warm air from the heater inside the blower outlet structure. However, since the partition plate and the airflow direction guide plate are fixed in the refrigerator outlet structure described in Patent Document 1, the front surface of the fan remains open even when the operation of the refrigerator is stopped. It becomes. For this reason, in order to perform a defrosting operation for melting and removing the frost attached to the fan by operating the heater arranged inside the outlet structure after stopping the operation of the refrigerator-freezer, this is provided on the front of the outlet structure. It is necessary to take additional measures such as arranging a structure for closing the door. Even if the fixed state of the partition plate and wind direction guide plate is released after the operation of the refrigerator / freezer is stopped and the outlet structure is closed, a lot of time and effort is required for preparation for the defrosting operation. Will be spent.

  In view of the above circumstances, the present invention suppresses the occurrence of temperature variations between the upper space and the lower space in the refrigerator-freezer, and adheres to the fan or cooler during operation of the refrigerator-freezer. It aims at providing the blower outlet structure for refrigerator-freezers which can transfer to the defrosting operation for melting and removing the done frost easily and quickly after the operation of the refrigerator-freezer is stopped.

Means and effects for solving the problems

  A refrigerator-freezer outlet structure according to a first device for achieving the above object is provided at a front surface of a fan in which cooling air cooled by the cooler is blown in a refrigerator-freezer having a cooler and a fan. And a frame body arranged to surround at least the front surface of the fan, the frame body being attached to the frame body, the longitudinal direction crossing the front surface of the fan, and the frame body A plurality of blades formed so as to extend along the width direction, and a rotation support mechanism that rotatably supports each of the plurality of blades with respect to the frame body at both end portions in the longitudinal direction; The blade is formed such that the mass of the lower part located below the rotation axis of the rotation support mechanism is larger than the mass of the upper part located above, and the front Characterized in that it is formed as towards the upper part is larger than the pressure receiving area lower portion the pressure of the cooling air blown out from the fan acts.

  According to this configuration, each blade supported rotatably with respect to the frame body by the rotation support mechanism has a pressure receiving area where the pressure of the cooling air blown from the fan acts on the upper portion rather than the lower portion. It is formed to be large. For this reason, when the cooling air is blown from the fan, each blade is inclined so that the upper portion having a large pressure receiving area opens upward toward the outside of the outlet structure by the wind pressure of the cooling air. Then, the cooling air is blown out obliquely upward from the opening in the outlet structure formed by the cooling air so that the blades are inclined upward. Thereby, even if the density of the cooling air blown out from the outlet structure is larger than the average density of the air in the refrigerator-freezer, it will flow in the upper space in the refrigerator-freezer for a while after being blown out. . For this reason, it is easy to prevent the cold air from staying in the lower space in the refrigerator-freezer, and the temperature variation between the upper space and the lower space can be efficiently suppressed. .

  Moreover, each blade | wing supported rotatably by the frame is formed so that the mass of a lower part may become larger than the mass of an upper part. For this reason, after the operation of the refrigerator-freezer stops, the wind pressure of the cooling air does not act, so that each blade that has been inclined obliquely has its lower mass part moving downward in the rotational direction. Become. As a result, immediately after the operation of the refrigerator-freezer is stopped, each blade stops in a posture in which the upper part is directed upward in the vertical direction and the lower part is directed downward in the vertical direction. For this reason, since the outlet structure closes immediately after the operation of the refrigerator-freezer is stopped, the heater disposed inside the outlet structure can be immediately operated to shift to the defrosting operation.

  Therefore, according to the present invention, it is possible to suppress the temperature variation between the upper space and the lower space in the refrigerator-freezer and to melt the frost attached to the fan or the cooler during the operation of the refrigerator-freezer. Thus, it is possible to provide an outlet structure for a refrigerator-freezer that can easily and quickly shift to a defrosting operation for removing the refrigerator-freezer after the operation of the refrigerator-freezer is stopped.

  The air outlet structure for a freezer according to a second device is the air outlet structure for a refrigerator-freezer according to the first device, wherein at least the upper part of the blade is formed in a flat plate shape.

  According to this configuration, since at least the upper part of each blade is formed in a flat plate shape, the blade can be efficiently rotated by the wind pressure of the cooling air blown from the fan. Therefore, useless pressure loss can be prevented from occurring at the outlet. Moreover, since the upper part is formed in a flat plate shape, the structure of the upper part having a smaller mass than that of the lower part can be easily realized by adjusting the thinness as appropriate.

  The air outlet structure for a freezer according to the third device is the air outlet structure for a freezer refrigerator according to the second device, wherein the blades are formed in a flat plate shape in which at least a part of the upper part and the lower part are integrally provided. In addition to being formed, the lower portion is provided with a weight member so that the mass is larger than that of the upper portion.

  According to this configuration, since each blade has at least a part of the upper part and the lower part formed as an integrated flat plate, the basic structure of the blade can be realized with a simple structure and a single flat plate is used. It can be easily manufactured. In addition, the lower portion having a mass larger than that of the upper portion can be easily formed only by providing the weight member in the lower portion.

  The air outlet structure for a freezer according to a fourth device is the air outlet structure for a refrigerator refrigerator according to any one of the first device to the third device, wherein the blade is rotated by cooling air blown from the fan. In this case, a restricting member that contacts the upper portion and restricts the rotatable range of the blade is attached.

  According to this configuration, since the rotatable range of the blade is restricted by the restriction member attached to the frame body, the angle at which the blade is inclined by the wind pressure of the cooling air is set to a desired angle by appropriately setting the arrangement of the restriction member. It can be set easily. Note that the regulating member may not be fixed to the frame body at one place at all times, and may be detachably attached to the frame body so that the mounting position can be changed. .

  FIG. 1 shows a cross-sectional view of a refrigerator-freezer 100 to which a refrigerator-freezer outlet structure 1 according to an embodiment of the present invention is applied. The refrigerator-freezer 100 is provided as a commercial refrigerator-freezer used for freezing and refrigeration of food. The refrigerator-freezer 100 is configured to include a heat-insulating box, a cooler, a fan, and the like. In the cross-sectional view of FIG. 1, the warehouse wall 100 a configured as a heat-insulating wall and food are carried in and out. The state where the inside of the warehouse is partitioned by the door 100b for the worker to enter and exit is shown. The refrigerator / freezer 100 has a refrigerator-freezer outlet structure 1 (hereinafter simply referred to as an “air outlet structure 1”), a cooler 2, a fan 3, an inlet structure 4, and a heater. 5, side wall 6, food shelf 7, etc. are arranged.

  The cooler 2, the fan 3, and the heater 5 are disposed in a region defined by the blowout port structure 1, the suction port structure 4, and the side wall 6. As the fan 3 rotates, the air in the cabinet is sucked from the suction port structure 4 in the direction of the arrow (a) in the figure, and the air is cooled by passing through the cooler 2. . The refrigerant in the cooler 2 is circulated with an outdoor unit (not shown) of the cooler 2 disposed outside the refrigerator / freezer 100. The outlet structure 1 is provided on the front surface of the fan 3, and the cooling air cooled by the cooler 2 is blown out from the outlet structure 1 as the fan 3 rotates.

  The suction port structure 4 is, for example, attached to a rectangular frame structure with a plurality of rubber sheets arranged in parallel in the horizontal direction with only the upper part fixed and the lower part suspended downward. Is made up of. Moreover, the heater 5 is comprised as a rod-shaped heater each arrange | positioned between the suction inlet structure 4 and the cooler 2, and between the cooler 2 and the fan 3, for example. In addition, a plurality of food shelves 7 are arranged in the cabinet, and a plurality of shelves on which foods are arranged are provided. The cooling air cooled by the cooler 2 and blown from the outlet structure 1 with the rotation of the fan 3 circulates in the cabinet, and the food placed on the shelf of the food shelf 7 is frozen and refrigerated. become. In addition, about the structure of the suction inlet structure 4, the heater 5, and the food shelf 7, it is not restricted to what is illustrated in FIG.

  2 to 4 show the outlet structure 1 of the present embodiment. FIG. 2 is a front view, FIG. 3 is a rear view, and FIG. 4 is a partial side view. As shown in FIGS. 2 to 4, the air outlet structure 1 includes a frame body 11, a plurality of blades 12, a rotation support mechanism 13, and the like. As described above, the air outlet structure 1 is disposed on the front surface of the fan 3 (see FIG. 1), and the front view of FIG. 2 shows the air outlet structure 1 viewed from the outside. The rear view of FIG. 5 shows a state in which the outlet structure 1 is viewed from the inside (from the fan 3 side).

  As shown in FIGS. 2 and 3, the frame body 11 is disposed so as to surround the front surface of the fan 3, and for example, four sides are configured by using members such as angle steel (an angle steel). It is formed by assembling. Further, the plurality of blades 12 are attached to the frame body 11, and the longitudinal direction crosses the front surface of the fan 3 and along the width direction of the frame body 11 (the direction of the double-headed arrow A in FIG. 2). It is formed to extend. That is, the plurality of blades 12 are arranged in parallel with each other along the width direction of the frame body 11 and aligned in the vertical direction.

  Further, as shown well in FIG. 4, the rotation support mechanism 13 includes a rotation shaft 19 and a rotation support block 20. The rotating shaft 19 is provided on both sides of each blade 12 in the longitudinal direction. The rotation support block 20 is formed with a hole into which the rotation shaft 19 is fitted in a loosely fitted state, and is fixed to the frame body 11. Since the rotation shaft 19 is fitted in the hole of the rotation support block 20 in a loosely fitted state and can rotate, the blades 12 can rotate with respect to the rotation support block 20 and the frame body 11 together with the rotation shaft 19. With such a rotation support mechanism 13, each of the plurality of blades 12 is rotatably supported with respect to the frame body 11 at both end portions in the longitudinal direction. In the present embodiment, the rotation support mechanism 13 includes the rotation shaft 19 attached to the blade 12 and the rotation support block 20 attached to the frame body 11. However, the rotation support mechanism 13 is not limited to this example. You may implement it changing suitably. For example, a rotating shaft may be fixed to the frame 11 and a block in which a hole into which the rotating shaft is fitted in a loosely fitted state is attached to the blade 12.

  As shown in FIG. 4, each blade 12 includes an upper portion 15 located above the rotation shaft 19 of the rotation support mechanism 13 and a lower portion 16 located below. . The upper portion 15 is formed in a flat plate shape, and the lower portion is composed of a flat plate portion 17 and a weight member 18 fixed to the flat plate portion 17. Moreover, the upper part 15 and the flat plate part 17 which is a part of the lower part 16 are formed in the flat plate shape provided integrally. The blade 12 is formed such that the mass of the lower portion 16 is larger than the mass of the upper portion 15 by providing the weight member 18 in the lower portion 16. The rotating shaft 19 is attached to the blade 12 at a position where the surface area of the upper portion 15 is larger than the surface area of the flat plate portion 17 of the lower portion 16. With this configuration, the blade 12 is formed so that the pressure receiving area on which the pressure of the cooling air blown from the fan 3 acts is larger in the upper portion 15 than in the lower portion 16.

  Further, the regulating member 14 is attached to the frame body 11 in a state of projecting to the front side (outside) of the frame body 11 on both sides in the width direction of the frame body 11, for example, as shown well in FIG. It is formed by attaching a pair of parallel steel bars 14a such as shaped steel to the frame 11 via another connecting member 14b. As shown in FIG. 2, the regulating member 14 is disposed so as to partially overlap at both end portions in the longitudinal direction of the blades 12 as viewed from the front side of the outlet structure 1. Thereby, the regulating member 14 comes into contact with the upper portion 15 and regulates the rotatable range of the blade 12 when the blade 12 rotates in the arrow B direction shown in FIG. 4 by the cooling air blown from the fan 3. It has become. As shown in FIGS. 2 to 4, rotation stoppers 21 are provided in the vicinity of the lower portion 16 of each blade 12 on both sides in the width direction of the frame body 11. The anti-rotation member 21 is provided to prevent the blade 12 from rotating in a direction opposite to the arrow B direction in FIG. 4 from a state in which the blade 12 is oriented in the vertical direction as shown in FIG. When the blade 12 is rotated in the direction opposite to the arrow B direction from the vertical posture of FIG. 4, it is provided to be engaged with the lower portion 16.

  Next, the operation of the outlet structure 1 having the above-described configuration will be described. FIG. 5 shows the outlet structure in which the pressure of the cooling air blown from the fan 3 acts to rotate the blades 12 to a predetermined angle (for example, an angle inclined 20 degrees upward with respect to the horizontal direction). 1 is a partial cross-sectional view of FIG. In addition, the arrow shown in the figure shows the flow direction of the cooling air blown out from the fan 3. First, when the operation of the refrigerator-freezer 100 is stopped, the fan 3 is not rotationally driven, so the cooling air is not blown out, and each blade 12 is in the state shown in FIGS. ing. That is, since the mass of the lower part 16 is larger than the mass of the upper part 15, each blade 12 supported rotatably by the rotation support mechanism 13 is stopped in a posture oriented in the vertical direction by the action of gravity. .

  When the operation of the refrigerator-freezer 100 is started from the above state, cooling air is blown out from the fan 3, and as shown in FIG. 5, the upper portion 15 having a large pressure receiving area is inclined toward the outside (front side). The blade 12 rotates so that the lower portion 16 having a small pressure receiving area is inclined inward. Then, the rotation range of the blade 12 is restricted by the upper end of the blade 12 coming into contact with the restriction member 14, and the blade 12 stops rotating at a predetermined angle determined by the position of the restriction member 14. On the other hand, when the operation of the refrigerator-freezer 100 is stopped, the cooling air is blown out from the fan 3, so that only the gravity acts on the blades 12 without the wind pressure of the cooling air acting, and the state shown in FIGS. It will be. Therefore, as soon as the refrigerator 100 is stopped, the air outlet structure 1 is immediately closed. And by operating the heater 5 shown in FIG. 1 and performing a heating operation in that state, it is possible to quickly shift to the defrosting operation.

  As described above, according to the air outlet structure 1 of the present embodiment, each blade 12 that is rotatably supported by the rotation support mechanism 13 with respect to the frame body 11 has the pressure of the cooling air blown from the fan 3. Is formed so that the upper portion 15 has a larger pressure receiving area than the lower portion 16. For this reason, when the cooling air is blown out from the fan 3, each blade 12 is inclined so that the upper portion 15 having a large pressure receiving area opens upward toward the outside of the outlet structure 1 by the wind pressure of the cooling air. Become. Then, the cooling air is blown obliquely upward from the opening in the air outlet structure 1 formed by the cooling air so that the blades 12 are inclined upward. Thereby, even if the density of the cooling air blown out from the blower outlet structure 1 is larger than the average density of the air in the refrigerator-freezer 100, it flows in the upper space in the refrigerator-freezer 100 for a while after being blown out. It will be. For this reason, it is easy to prevent the cold air from easily staying in the lower space in the refrigerator 100, and efficiently suppressing the temperature variation between the upper space and the lower space. it can.

  Further, each blade 12 rotatably supported by the frame body 11 is formed so that the mass of the lower portion 16 is larger than the mass of the upper portion 15. For this reason, after the operation of the refrigerator-freezer 100 is stopped, the wind pressure of the cooling air does not act, so each blade 12 that has been inclined obliquely moves the lower portion 16 having a large mass downward in the rotational direction. Will do. Thus, immediately after the operation of the refrigerator 100 is stopped, the blades 12 are stopped in a posture in which the upper portion 15 is directed upward in the vertical direction and the lower portion 16 is directed downward in the vertical direction. For this reason, since the outlet structure 1 is closed immediately after the operation of the refrigerator / freezer 100 is stopped, the heater 5 disposed inside the outlet structure 1 can be operated as it is to shift to the defrosting operation. .

  Therefore, according to this embodiment, while suppressing the dispersion | variation in the temperature between the upper space in the refrigerator-freezer 100, and the lower space, it is set to the fan 3 and the cooler 2 during the driving | operation of the refrigerator-freezer 100. It is possible to provide an outlet structure for a refrigerator that can easily and quickly shift to a defrosting operation for melting and removing the attached frost after the operation of the refrigerator-freezer 100 is stopped.

  Further, according to the air outlet structure 1, since at least the upper portion 15 of each blade 12 is formed in a flat plate shape, the blade 12 can be efficiently rotated by the wind pressure of the cooling air blown from the fan 3, Since the flow resistance is small with a flat blade structure, it is possible to suppress the occurrence of useless pressure loss at the outlet. In addition, since the upper portion 15 is formed in a flat plate shape, the structure of the upper portion 15 having a mass smaller than that of the lower portion 16 can be easily realized by appropriately adjusting the thickness thereof.

  Moreover, according to the blower outlet structure 1, since each blade | wing 12 is partly formed in the flat plate shape in which the upper part 15 and the lower part 16 (flat plate part 17) were integrated, the basic structure of the blade | wing 12 is simplified. It can be realized with a structure and can be easily manufactured using a single flat plate. Further, the lower portion 16 having a mass larger than that of the upper portion 15 can be easily formed only by providing the weight member 18 on the lower portion 16.

  Further, according to the air outlet structure 1, the rotatable range of the blade 12 is restricted by the restriction member 14 attached to the frame body 11. Therefore, the blade can be driven by the wind pressure of the cooling air by appropriately setting the arrangement of the restriction member 14. Can be easily set to a desired angle.

  The embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various modifications can be made as long as they are described in the claims of the utility model registration. For example, the following modifications may be made.

(1) In this embodiment, the case where the mass of the lower portion 16 is larger than the mass of the upper portion 15 by providing the weight member 18 on the lower portion 16 of the blade 12 has been described as an example. It does not have to be. FIG. 6A to FIG. 6C are explanatory views of modifications of the blades, and are side views of the blades according to each modification. Each of the blades (12a, 12b, 12c) according to the modified examples of FIGS. 6 (a) to 6 (c) has a pressure receiving area where the pressure of the cooling air blown from the fan acts on the rotating shafts (19a, 19b). , 19c) is formed so that the upper part (15a, 15b, 15c) located on the upper side is larger than the lower part (16a, 16b, 16c) located on the lower side. And each blade | wing (12a, 12b, 12c) is comprised so that the mass of a lower part (16a, 16b, 16c) may become larger than the mass of an upper part (15a, 15b, 15c). . However, the blade 12a of the modification of FIG. 6A is formed so that the mass is smaller than that of the lower portion 16a by forming a hollow portion in the upper portion 15a. 6B, the blade 12b is formed such that the thickness of the upper portion 15b is thinner than that of the lower portion 16b, so that the mass of the upper portion 15b is lower than the mass of the lower portion 16b. Is formed to be small. 6C, the upper portion 15c is formed of, for example, a resin, and the lower portion 16c is formed of, for example, an iron-based material having a specific gravity higher than that of the resin. It is formed so that the mass of the upper portion 15c is smaller than the mass of the side portion 16c.

(2) In the present embodiment, the case where the restricting member 14 is fixed to the frame body 11 has been described as an example. However, the restricting member is not always fixed to one place with respect to the frame body. Alternatively, it may be detachably attached to the frame so that the attachment position can be changed.
