Description

The present invention relates to a refrigerator for cooling and storing foods and the like inside a storage chamber, and particularly to a refrigerator having a defrosting device having excellent efficiency.

A general refrigerator is provided with a refrigeration cycle device, and the evaporator included in the refrigeration cycle device has a large number of cooling fins arranged in parallel and a refrigerant pipe in contact with the cooling fins.

When the air inside the refrigerator is cooled by this evaporator, the temperature of the cooling fins is about -30 degrees, so the moisture contained in the air flowing between the cooling fins adheres to the surface of the cooling fins and becomes solid and frosts. It becomes. Such a phenomenon is also generally called frost formation.

As this frost formation progresses, the gaps between the cooling fins are occupied by frost, which hinders the flow of cold air. In order to prevent this phenomenon, defrosting operation is performed regularly.

A defrosting system provided in a general refrigerator 100 will be described with reference to FIG. Below the evaporator 101 that cools the air blown to each storage of the refrigerator 100, a defrost heater 102 for melting and removing the frost adhering to the evaporator 101 is arranged. Further, a protective plate 103 is arranged between the defrost heater 102 and the evaporator 101 to prevent the molten water dripping when the evaporator 101 is defrosted from coming into contact with the defrost heater 102. There is. Since the protective plate 103 is a long member made of a steel plate extending along the width direction of the refrigerator 100, both end portions are bent downward in order to increase its mechanical strength.

In the defrosting operation, the air blown from the cooling chamber to the storage chamber is stopped, the supply of the refrigerant to the evaporator 101 is stopped, and the evaporator is heated by the defrosting heater 102 arranged below the evaporator 101. When warm air is supplied to the evaporator 101 by energizing the defrost heater 102 in this way, the frost adhering to the cooling fins of the evaporator 101 is heated and melted to be removed. After the defrosting operation is completed, the refrigeration cycle is operated again, and the cold air cooled by the evaporator 101 is blown to each storage chamber.

Refrigerators having the above-mentioned defrosting mechanism are described in, for example, Patent Document 1 and Patent Document 2 below.

However, in the refrigerator 100 having the above-mentioned structure, there is a problem that the circulation of cold air is hindered due to the protective plate 103 that protects the defrost heater 102. Specifically, since the protective plate 103 is arranged parallel to the horizontal direction in the vicinity of the lower part of the evaporator 101, the effective air passage which is the air passage in which cold air is blown into the evaporator 101 is slightly provided. Is also hindering. Further, the air blown to each storage chamber of the refrigerator 100 flows through the evaporator 101 from the lower side to the upper side, but the protective plate 103 stagnates the air flow, so that the amount of air circulation increases. It sometimes dropped. If this happens, cold air cannot be efficiently supplied to each storage chamber, and there arises a problem that the electric power required for operating the refrigerator increases.

Further, there is also a problem that the cycle of the defrosting step is shortened due to the protective plate 103 that protects the defrosting heater. Specifically, in the upper part of the protective plate 103, the air flow is obstructed by the protective plate 103, so that the density of the frost 104 formed on the evaporator 101 becomes low, and the frost 104 forms earlier than the other parts. The air passage becomes blocked. Therefore, even when looking at the evaporator 101 as a whole, the time until the air passage is blocked by the frost 104 is shortened. Therefore, as the defrosting cycle becomes shorter, the frequency of defrosting by heating the defrosting heater 102 increases, and the electric power required for operating the refrigerator 100 increases.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a refrigerator in which the electric power required for operation is reduced by optimizing the flow of air blown to the evaporator.

The refrigerator of the present invention includes a compressor that compresses the refrigerant, a condenser that condenses the compressed refrigerant, an expansion means that expands the condensed refrigerant, and an evaporator that evaporates the expanded refrigerant. A refrigerating cycle connected via a pipe, a heating means arranged below the evaporator, a cooling chamber in which the evaporator is housed, and air blown from the cooling chamber toward the storage chamber. Is arranged between the air outlet through which the air is passed, the return port through which the air that cools the storage chamber and returns to the cooling chamber passes, and the heating means and the evaporator, and is arranged in a direction away from the return port. The storage chamber is provided with a protective plate that inclines upward toward the refrigerating chamber, and the storage chamber is provided with a freezing chamber that is cooled in a refrigerating temperature zone formed in front of the cooling chamber and a refrigerating temperature zone that is arranged above the freezing chamber. The lower end of the partition body which has a refrigerating chamber which is cooled to the above and a vegetable chamber which is arranged below the freezing chamber and is cooled in the refrigerating temperature zone and which divides the cooling chamber in the front is the upper end of the heating means. The return port is formed below the partition body through which the air returning to the cooling chamber passes, and the protective plate is formed from the side of the return port to the front portion and the intermediate portion. The front portion is inclined upward toward a direction away from the return port, the intermediate portion extends substantially horizontally, and the rear portion extends from the return port. The air that inclines upward toward the distance and returns from the freezer compartment, the refrigerator compartment, and the vegetable compartment passes through the return port, enters the cooling chamber, and moves upward along the protective plate. It is characterized in that it is blown toward the air and comes into contact with the evaporator.

Further, in the refrigerator of the present invention, the evaporator has a plurality of cooling fins and a refrigerant pipe penetrating the cooling fins, and the protective plate has a longitudinal direction along a direction in which the cooling fins are arranged. It has a long shape having a lateral direction orthogonal to the longitudinal direction, and the protective plate is characterized in that it is inclined along the lateral direction.

Further, in the refrigerator of the present invention, the protective plate is characterized in that it exhibits a curved shape or a bent shape.

The refrigerator of the present invention includes a compressor that compresses the refrigerant, a condenser that condenses the compressed refrigerant, an expansion means that expands the condensed refrigerant, and an evaporator that evaporates the expanded refrigerant. A refrigerating cycle connected via a pipe, a heating means arranged below the evaporator, a cooling chamber in which the evaporator is housed, and air blown from the cooling chamber toward the storage chamber. Is arranged between the air outlet through which the air is passed, the return port through which the air that cools the storage chamber and returns to the cooling chamber passes, and the heating means and the evaporator, and is arranged in a direction away from the return port. The storage chamber is provided with a protective plate that inclines upward toward the refrigerating chamber, and the storage chamber is provided with a freezing chamber that is cooled in a refrigerating temperature zone formed in front of the cooling chamber and a refrigerating temperature zone that is arranged above the freezing chamber. The lower end of the partition body which has a refrigerating chamber which is cooled to the above and a vegetable chamber which is arranged below the freezing chamber and is cooled in the refrigerating temperature zone and which divides the cooling chamber in the front is the upper end of the heating means. The return port is formed below the partition body through which the air returning to the cooling chamber passes, and the protective plate is formed from the side of the return port to the front portion and the intermediate portion. The front portion is inclined upward toward a direction away from the return port, the intermediate portion extends substantially horizontally, and the rear portion extends from the return port. The air that inclines upward toward the distance and returns from the freezer compartment, the refrigerator compartment, and the vegetable compartment passes through the return port, enters the cooling chamber, and moves upward along the protective plate. It is characterized in that it is blown toward the air and comes into contact with the evaporator. Therefore, the air flowing toward the evaporator inside the refrigerator moves smoothly along the inclined protective plate, so that the protective plate is prevented from obstructing the air flow, and the cooling efficiency in the evaporator is suppressed. Can be improved. In addition, since frost formation proceeds at a substantially uniform density in the evaporator, the blockage time until the air passage is blocked by frost formation can be lengthened, and the number of defrosting times associated with the operation of the refrigerator is reduced. It is possible to reduce the power consumption.

Further, in the refrigerator of the present invention, the evaporator has a plurality of cooling fins and a refrigerant pipe penetrating the cooling fins, and the protective plate has a longitudinal direction along a direction in which the cooling fins are arranged.

Further, in the refrigerator of the present invention, the protective plate is characterized in that it exhibits a curved shape or a bent shape. Therefore, since the protective plate is reinforced by forming the bending point, it is possible to prevent the intermediate portion of the long protective plate from being deformed.

Hereinafter, the refrigerator according to the embodiment of the present invention will be described in detail with reference to the drawings. In the following description, each direction of up, down, front, back, left and right will be used, and the left and right refer to the case where the refrigerator 10 is viewed from the front. Further, in each figure, the flow of cold air is indicated by a dotted arrow.

FIG. 1 is a cross-sectional view of the right side of the refrigerator 10 according to the present embodiment. FIG. 2 is a front schematic diagram showing an outline of the supply air passage of the refrigerator 10.

As shown in FIG. 1, the refrigerator 10 includes a heat insulating box 11 as a main body, and a storage chamber for storing food and the like is formed inside the heat insulating box 11. As the storage room, the uppermost stage is the refrigerating room 12, the lower part is the freezing room 13, and the lowermost part is the vegetable room 14. Here, the inside of the freezing chamber 13 may be divided into several small freezing chambers. For example, the freezing chamber 13 may have an ice making chamber and an upper freezing chamber in the upper portion, and may have a lower freezing chamber in the lower portion.

The front surface of the heat insulating box 11 is open, the front opening of the refrigerator compartment 12 is closed by a door 20 having heat insulating properties, the front opening of the freezing chamber 13 is closed by the door 21, and the front opening of the vegetable compartment 14 is closed. Is closed by the door 22. The door 20 is rotatably attached to the heat insulating box 11, and the doors 21 and 22 are rotatably attached to the heat insulating box 11. These doors 20 and the like also adopt the same heat insulating structure as the heat insulating box 11.

The refrigerating chamber 12 and the freezing chamber 13 are separated by a heat insulating partition wall 23. Similarly, the freezing chamber 13 and the vegetable compartment 14 are separated by a heat insulating partition wall 24.

The back side of the freezing chamber 13 is partitioned by a front cover 33, which is a partition member made of synthetic resin, and an air passage 36 is formed. Specifically, the air passage 36 is a space formed between the partition body 31 and the front cover 33 assembled in front of the partition body 31, and serves as an air passage through which cold air cooled by the evaporator 16 flows.

The front cover 33 is formed with an outlet 32 which is an opening for blowing cold air into the freezing chamber 13. Further, on the lower back surface of the freezing chamber 13, a return port 40 for returning air from the freezing chamber 13 to the cooling chamber 30 is formed.

An air passage 26 for supplying cold air to the refrigerating chamber 12 is formed on the back surface of the refrigerating chamber 12. The air passage 26 is formed with an air outlet 25 for flowing cold air into the refrigerating chamber 12. The air passage 36 and the air passage 26 communicate with each other via a damper 27. The damper 27 is for controlling the flow rate of the cold air supplied to the refrigerating chamber 12 to appropriately maintain the temperature inside the refrigerating chamber 12.

Further behind the air passage 36, a cooling chamber 30 separated by a partition 31 is provided. A blower port 29 connecting the cooling chamber 30 and the air passage 36 is formed in the upper part of the partition body 31, and a blower 28 for supplying cold air to each storage chamber is arranged in the blower port 29. There is. Below the cooling chamber 30, a return port 49 for sucking cold air from each storage chamber into the inside of the cooling chamber 30 is formed.

Inside the cooling chamber 30, an evaporator 16 for cooling the circulating air is arranged. The evaporator 16 is connected to a compressor 15, a radiator (not shown), and an expansion means (not shown) via a refrigerant pipe, and constitutes a vapor compression type refrigeration cycle circuit. As the refrigerant for the refrigeration cycle, for example, isobutane (R600a) is used.

With reference to FIG. 2, the operation of cooling each storage by circulating cold air in the refrigerator 10 having the above-described configuration will be described. FIG. 2 is a front view of the refrigerator 10 showing a path through which cold air circulates.

First, the cold air inside the cooling chamber 30 cooled by the evaporator 16 is supplied to the refrigerating chamber 12, the freezing chamber 13, and the vegetable compartment 14. Specifically, the cold air from the cooling chamber 30 is blown by the blower 28, and is supplied to the refrigerating chamber 12 via the air passage 36, the damper 27, the air passage 26, and the air outlet 25. Further, a part of the cold air blown by the blower 28 is supplied to the freezing chamber 13 via the air passage 36 and the air outlet 32. Further, a part of the cold air blown by the blower 28 is supplied to the vegetable compartment 14 via the air passage 46 and the outlet 43.

The cold air that has cooled each storage chamber as described above returns to the cooling chamber 30. Specifically, the air that has cooled the refrigerating chamber 12 returns to the vicinity of the lower end of the cooling chamber 30 via the return port 45, the return air passage 47, and the return port 53. The cold air that has cooled the freezing chamber 13 returns to the vicinity of the lower end of the cooling chamber 30 via the return port 40. As shown in FIG. 1, the cold air that has cooled the vegetable compartment 14 returns to the vicinity of the lower end of the cooling chamber 30 via the return port 48 and the return air passage 44.

The cold air cooled by the evaporator 16 circulates through the above-mentioned ventilation path and return path based on the instruction of the control device (not shown), so that the refrigerating chamber 12, the freezing chamber 13 and the vegetable chamber 14 have a predetermined low temperature. Cooled to state.

Next, a configuration for removing the frost 50 of the evaporator 16 will be described with reference to FIG. FIG. 3A is a side sectional view showing the evaporator 16 and its peripheral portion, and FIG. 3B is an enlarged side sectional view showing the defrost heater 34 and its peripheral portion, and FIG. 3C. ) And FIG. 3 (D) are side sectional views showing the protective plate 35 in an enlarged manner.

With reference to FIG. 3A, a defrost heater 34 as a defrosting device for defrosting the evaporator 16 is arranged below the evaporator 16 inside the cooling chamber 30. The defrost heater 34 is a heating means, and is configured by incorporating a heating element in a tubular glass tube. When the defrosting heater 34 is energized, heat is generated, and the frost attached to the evaporator 16 due to the warm air heated by this heat. 50 is melted. Further, the lower end of the partition body 31 that partitions the cooling chamber 30 is arranged below the upper end of the defrost heater 34. By doing so, it is possible to prevent the warm air heated by the defrost heater 34 from leaking from the cooling chamber 30 to the freezing chamber 13 side.

A protective plate 35 is arranged between the defrost heater 34 and the evaporator 16. The protective plate 35 is a plate-shaped member made of a metal such as stainless steel, and has an elongated elongated shape having a longitudinal direction along the width direction of the refrigerator 10. The length of the protective plate 35 in the width direction of the refrigerator 10 is about the same as that of the evaporator 16. As will be described later, the shape of the protective plate 35 in the lateral direction is an inclined shape as shown in FIG. 3 (B), and the shape of the protective plate 35 in the longitudinal direction is linear in the horizontal direction as shown in FIG. It has an elongated shape.

With reference to FIG. 3B, the length of the protective plate 35 in the depth direction of the refrigerator 10 is set to be slightly wider than that of the defrost heater 34. Further, the front end of the protective plate 35 is arranged in front of the front end of the defrost heater 34, and the rear end of the protective plate 35 is arranged behind the rear end of the defrost heater 34. As a result, the defrost heater 34 is totally protected from above by the protective plate 35, and even if the melted water generated by melting the frost 50 in the defrosting process drops downward, the melted water is the defrost heater. Contact with 34 is suppressed.

The shape of the protective plate 35 when viewed from the side is an inclined shape that inclines upward toward the rear. In other words, the protective plate 35 has an inclined shape that is inclined upward in a direction away from the return port 49 in which the cold air returns to the cooling chamber 30.

The shape of the protective plate 35 when viewed from the side may be a flat shape, but in this embodiment, the protective plate 35 has a curved shape or the like. Such matters will be described with reference to FIGS. 3 (C) and 3 (D).

With reference to FIG. 3C, the shape of the protective plate 35 when viewed from the side is a curved shape in which the intermediate portion thereof is curved. Specifically, the front portion of the protective plate 35 is curved so as to be convex upward, and the rear portion of the protective plate 35 is curved so as to be convex downward. In this way, by making the shape of the protective plate 35 when viewed from the side curved, the mechanical strength of the protective plate 35 is increased, and the intermediate portion of the protective plate 35 in the longitudinal direction is curved by its own weight. It can be deterred.

With reference to FIG. 3D, here, the protective plate 35 has a bent shape in which a plurality of bent portions are formed. Specifically, the front portion of the protective plate 35 is an inclined surface that inclines upward toward the rear, the intermediate portion of the protective plate 35 is a parallel surface that extends along the horizontal direction, and the rear portion of the protective plate 35 is. It is an inclined surface that inclines upward toward the rear. A bent portion is formed at the boundary between each of these surfaces. Even with such a shape, the mechanical strength of the protective plate 35 can be improved, and bending of the protective plate 35 in the longitudinal direction can be suppressed.

Further, by forming the protective plate 35 into a curved shape or a bent shape as described above, cold air blown from below to above can flow smoothly along the protective plate 35 having such a shape. The effective air passage for cold air can be expanded.

FIG. 4 is a front view of the evaporator 16 and the return air passage 47 included in the refrigerator 10 as viewed from the front. With reference to this figure, the return air passage 47 in which the cold air that has cooled the refrigerating chamber 12 returns to the cooling chamber 30 is formed on the right side of the evaporator 16. Further, the return air passage 47 communicates with the cooling chamber 30 via a return port 53 formed below the lower end of the evaporator 16.

The evaporator 16 is composed of a plurality of cooling fins 51 arranged in the width direction at predetermined intervals, and a refrigerant pipe 52 arranged so as to penetrate the cooling fins 51. The evaporator 16 has a plurality of rows arranged at equal intervals in the height direction in units of rows in which a predetermined number of cooling fins 51 are arranged in the width direction. The refrigerant pipe 52 is formed in a meandering manner so as to penetrate the cooling fins 51 in each row.

The flow of cold air in the cooling chamber 30 of the refrigerator 10 of the present embodiment will be described with reference to FIGS. 3 and 4.

First, with reference to FIG. 3, the flow of cold air in the peripheral portion of the protective plate 35 during cooling will be described. In this embodiment, as described above, the protective plate 35 is arranged so as to be inclined from the horizontal direction. More specifically, the protective plate 35 is inclined upward in the direction away from the return port 49. Therefore, the cold air returned from the return port 49 to the cooling chamber 30 rises inside the cooling chamber 30 due to the blowing function of the blower 28, but the flow of the cold air stagnates inside the cooling chamber 30 with the protective plate 35. There is no. The cold air returned from the return port 49 to the cooling chamber 30 smoothly rises inside the cooling chamber 30 along the inclined protective plate 35. After that, the cold air cooled by exchanging heat with the evaporator 16 is blown to each storage chamber via the above-mentioned air passage.

Therefore, the air that cools each storage chamber and returns to the cooling chamber 30 is smoothly blown upward along the inclined protective plate 35 inside the cooling chamber 30 after passing through the return port 49, and the air is blown upward. The flow of air is prevented from being obstructed by the protective plate 35. That is, in the region below the evaporator 16, the effective air passage through which air is blown can be increased. From this, it is possible to improve the efficiency of circulating air, shorten the time for operating the compressor 15 to cool each storage chamber, and reduce the energy consumed in the cooling operation to realize energy saving. Can be done.

As described above, when the returned cold air comes into contact with the evaporator 16, the moisture contained in the returned cold air adheres to the evaporator 16 and freezes, so that the lower end of the evaporator 16 is as shown in FIG. 3 (B). Frost 50 adheres in the vicinity. In particular, the cold air returning from the vegetable compartment 14 and the refrigerating chamber 12 contains a large amount of water emitted from foods and the like stored in the vegetable compartment 14 and the refrigerating chamber 12, so that the cold air causes the frost 50 to grow at an early stage. Become.

In this embodiment, as described above, the flow of cold air rising inside the cooling chamber 30 does not stagnate in the protective plate 35. Therefore, even in the upper portion of the protective plate 35, dense frost 50 is uniformly frosted on the lower end portion of the evaporator 16 as in the other portions. Therefore, it is possible to lengthen the time until the lower end portion of the evaporator 16 is blocked by the frost 50, lengthen the interval of the defrosting process, and reduce the energy required for operating the refrigerator 10.

Further, referring to FIG. 4, the cold air returning from the refrigerating chamber 12 to the cooling chamber 30 is blown from the side below the protective plate 35 and the defrosting heater 34, and then flows upward toward the evaporator 16. .. Also in this cold air path, since the protective plate 35 is inclined as described above, the protective plate 35 is suppressed from obstructing the flow of the cold air, so that the effective air passage in which the cold air rises is increased. , The circulation of cold air can be made more efficient.

When the cool air is continuously cooled by the evaporator 16, a large amount of frost 50 adheres to the cooling fins 51 shown in FIG. 4, the gap between the cooling fins 51 is closed by the frost 50, and the cold air moves upward. It cannot be circulated and the efficiency of cooling by the evaporator 16 decreases. In addition, the frost 50 inhibits heat exchange. Therefore, a defrosting process for removing the frost 50 is performed. The defrosting process is performed based on an instruction of a control device (not shown) when the time for continuously cooling the cold air in the evaporator 16 exceeds a certain level or when the cooling load exceeds a certain level. In the defrosting process, the blower 28 is stopped and the compressor 15 in the refrigeration cycle is stopped. Further, the defrost heater 34 is energized to raise the heated warm air, and the warm air is sent to the evaporator 16 inside the cooling chamber 30 to melt the frost 50 adhering to the evaporator 16. The dissolved water generated by melting the frost 50 drops on the dew pan 42 and then moves to an evaporating dish (not shown). When the defrosting process is completed after a predetermined time elapses or when the internal temperature of the cooling chamber 30 reaches a certain level, a control device (not shown) terminates the energization of the defrosting heater 34, and the blower 28 and the blower 28 and The compressor 15 is operated again, and the cold air cooled by the evaporator 16 is blown to each storage chamber.

In this embodiment, as described above, the protective plate 35 has an inclined shape inclined from the horizon. Therefore, the updraft due to the warm air heated by the defrost heater 34 does not stagnate on the protective plate 35, and smoothly rises toward the evaporator 16 along the inclined protective plate 35. From this, it becomes possible to efficiently supply the warm air heated by the defrost heater 34 to the evaporator 16, and the frost 50 adhering to the evaporator 16 can be melted at an early stage. Therefore, the time required to energize the defrost heater 34 can be shortened, and the energy required for the defrosting process can be reduced.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.
