[0001] The present disclosure relates to refrigerators. Background Art

[0002] Japanese Patent Publication No. 2004-077088 discloses a food cooling device having a cooling chamber for storing and cooling food; a cold air supply device for generating and supplying cold air into the cooling chamber; and a cold air flow emitting structure for emitting the cold air flow as a cold air jet into the cooling chamber.

[0003] Problem that the invention aims to solve

[0004] In the food cooling device described in Patent Document 1, when cooling the cooling object, the operation of the food cooling device needs to be accelerated. Therefore, a peak of power consumption occurs, and power consumption is high when cooling the cooling object rapidly. Summary of the invention

[0005] The present disclosure provides a freezer capable of rapidly freezing food in a short time without reducing the quality of the food.

[0006] Solutions for solving problems

[0007] The first type of freezer comprises: a freezer chamber, which accommodates a frozen object; a cold air passage, which has an intake port for sucking air from the freezer chamber, and an outlet for blowing cold air into the freezer chamber; a fan, which is arranged in the cold air passage and blows the cold air in the cold air passage from the outlet to the freezer chamber; a heat storage energy component, which has a heat exchange component and a solid block-shaped heat capacity component and is arranged in the cold air passage, the heat exchange component having a plurality of fins, and the heat capacity component is thermally integrated with the heat exchange component; and a refrigerant pipe, which provides cold energy to the heat storage energy component.

[0008] According to the refrigerator, a heat storage component is arranged in the cold air passage. In the heat storage component, cold energy is provided through the refrigerant pipe and cold energy is stored. When rapid freezing is performed, the rotation speed of the fan is increased, the air in the freezing chamber is sucked in from the suction port of the cold air passage, contacts the heat storage component, and cold air is blown out from the blowing port to the freezing chamber.

[0009] By using the cold energy stored in the thermal storage member in this manner, the objects to be frozen stored in the freezing chamber can be rapidly frozen in a short time and with low power consumption compared to a refrigerator without a thermal storage member in the cold air passage.

[0010] In addition, according to the refrigerator, the thermal storage member is formed by thermally integrating the heat exchange member having a plurality of fins with the solid block-shaped heat capacity member. Therefore, compared with a simple block-shaped thermal storage member, it is possible to store cold energy and release a large amount of cold energy through the heat exchange member.

[0011] A refrigerator according to a second aspect is the refrigerator according to the first aspect, wherein the refrigerant pipe is buried in the thermal storage member.

[0012] According to this refrigerator, the refrigerant pipe is buried in the thermal energy storage member, thereby improving the energy storage effect.

[0013] A third embodiment of a refrigerator is a refrigerator described in the first embodiment or the second embodiment, wherein the heat exchange member is a plurality of radiators having long grooves formed on the back side for embedding the refrigerant tubes, and the heat capacity member is a block having the same size as the size of the plurality of radiators combined on a plane, the heat capacity member having a long groove formed therein, overlapping the back side, and the refrigerant tubes are buried together with the plurality of radiators.

[0014] According to the refrigerator, the heat exchange member is a plurality of radiators having long grooves formed on the back side for embedding refrigerant tubes. In addition, the heat capacity member is a block having the same size as the size of the plurality of radiators combined on a plane, and the heat capacity member is formed with a long groove, overlaps with the back side, and buries the refrigerant tubes together with the plurality of radiators. In the refrigerator, by burying the refrigerant tubes using the plurality of radiators and the block, the heat exchange between the refrigerant tubes and the thermal energy storage member is easily promoted. In addition, by separating the overlapping heat exchange member and the heat capacity member, the refrigerant tubes can be easily replaced.

[0015] A refrigerator according to a fourth aspect is the refrigerator according to any one of the first to third aspects, wherein the plurality of fins of the thermal storage member extend along the flow of cold air.

[0016] According to this refrigerator, since the cold air flows between the fins, the contact area of ​​the cold air becomes larger and the heat exchange rate is improved. In addition, the flow of the cold air is not hindered, and the flow rate of the cold air is not reduced due to the generation of eddy currents, etc.

[0017] A refrigerator according to a fifth aspect is the refrigerator according to any one of the first to fourth aspects, wherein a gap is formed between the thermal storage member and a wall of the cold air passage.

[0018] According to this refrigerator, since the gap between the thermal storage member and the wall is also used as an air passage, the contact area between the thermal storage member and the wind is increased, so that the heat exchange rate of the thermal storage member can be improved.

[0019] A refrigerator according to a sixth aspect is the refrigerator according to any one of the first to fifth aspects, wherein the thermal storage member is an aluminum member having a surface area of ​​0.1 m2 per 1 kg weight. 2 More than 80% of the surface area is exposed to cold wind.

[0020] According to this refrigerator, by using the heat storage member as an aluminum member, the thermal conductivity and heat dissipation are improved, thereby improving the energy storage efficiency and heat exchange rate. In addition, by setting the surface area per 1 kg weight of the aluminum member to 0.1 m 2 The surface area is set to be more than 80% exposed to the cold wind, thereby improving the energy storage / heat dissipation efficiency. In addition, the aluminum component is processed to have a surface area of ​​0.1m per 1kg weight of the aluminum component. 2 As described above, the thermal storage member can be made lighter and the material cost can be reduced. In addition, it can be set so that 80% or more of the surface area of ​​the thermal storage member is exposed to the cold wind.

DETAILED DESCRIPTION

[0027] Hereinafter, an example of an embodiment of the present disclosure will be described with reference to the accompanying drawings. In addition, in each of the drawings, the same reference numerals are used to indicate the same or equivalent constituent elements and components. In addition, for ease of description, the dimensional ratios of the drawings are exaggerated and sometimes differ from the actual ratios.

[0028] In addition, the arrow H shown in each figure indicates the upward direction of the refrigerator 10 in the vertical direction, the arrow W indicates the width direction of the refrigerator 10 in the horizontal direction, and the arrow D indicates the depth direction of the refrigerator 10 in the horizontal direction.

[0029] (structure)

[0030] Figure 1 is a side cross-sectional view of a refrigerator 10 according to an embodiment of the present disclosure, Figure 2 FIG. 1 is a front cross-sectional view of a refrigerator 10 according to an embodiment of the present disclosure. Figure 1 and Figure 2 As shown, the refrigerator 10 of the present disclosure is configured to be divided into a freezing chamber 20 , a machine chamber 30 , and a cold air passage 50 by a partition wall 12 in a housing 14 .

[0031] (Freezer 20)

[0032] like Figure 1 and Figure 2 As shown, the freezer compartment 20 is a region that constitutes the majority of the freezer 10 and accommodates the Figure 1 The door 11 (left side of the drawing) is provided with a frozen object 26. In addition, the freezing chamber 20 is a region where air circulates through a cold air passage 50 as described later, and is provided with cooled air (hereinafter referred to as cold air). Figure 1 As shown, the freezing chamber 20 may also be configured to have a plurality of areas divided into a main freezing chamber 22 and a sub-freezing chamber 24 .

[0033] (Machinery Room 30)

[0034] As an example, the machine room 30 is a region where a compressor 34, a condenser 36, a dryer 38, an expansion valve 40, and a pressure accumulator 42 are arranged in series through a refrigerant pipe 32 through which refrigerant flows. The compressor 34 is a device that compresses gaseous refrigerant. The refrigerant compressed by the compressor 34 flows into the condenser 36 and liquefies while cooling. The liquefied refrigerant flows into the dryer 38, and the moisture in the liquefied refrigerant is removed by the dryer 38. The refrigerant flowing out of the dryer 38 flows into the expansion valve 40, and the expansion valve 40 expands the refrigerant until it becomes a gas, thereby the refrigerant flows out in a state of lowering the temperature. The refrigerant after passing through the expansion valve 40 flows into the thermal energy storage component 60 in the cold air passage 50 as described later, and releases cold energy (absorbs heat from the thermal energy storage component 60). The refrigerant after releasing the cold energy is regulated in pressure by the pressure accumulator 42 of the machine room 30. The refrigerant whose pressure is regulated by the pressure accumulator 42 flows into the compressor 34 again and is compressed, thereby obtaining the refrigeration cycle of the freezer of this embodiment.

[0035] (Cold air channel 50)

[0036] The cold air passage 50 is provided with the heat storage energy member 60 and the fan 54 of the present disclosure, and is a region of the air passage that forms an air circulation together with the freezing chamber 20. In the present embodiment, as an example, the air in the cold air passage 50 is driven by the rotation of the fan 54, so that the air in the cold air passage 50 is moved from the upper side (at the bottom) of the cold air passage 50 to the lower side. Figure 1 and Figure 2 The air in the freezer compartment 20 is blown out of the blower outlet 58 (on the upper side of the drawing) to the freezer compartment 20. In addition, the air in the freezer compartment 20 is blown out of the cool air duct 50 from the lower side of the cool air duct 50 (on the upper side of the drawing) by the rotation of the fan 54. Figure 1 and Figure 2 The air is sucked into the cold air passage 50 through the suction port 56 (lower side of the drawing in FIG. 1 ). Thus, in the cold air passage 50, as shown by arrow F, the air flows from the lower side toward the upper side.

[0037] In addition, the speed of the rotation drive of the fan 54 is controlled by a controller not shown. In addition, in the present embodiment, the controller not shown divides the operation state of the rotation drive of the fan 54 into two types: "rapid freezing operation mode" and "temperature maintenance operation mode" for control. In the present embodiment, as an example, the controller controls the speed of the rotation drive of the fan 54 based on the temperature in the freezing chamber 20, thereby controlling the flow rate of air circulating in the cold air passage 50 and the freezing chamber 20.

[0038] (Thermal Energy Storage Component 60)

[0039] like Figure 3 As shown, the thermal storage member 60 of the present embodiment includes a heat exchange member 62 , a block 68 , and a refrigerant pipe 72 .

[0040] like Figure 3 As shown in the figure, the heat exchange member 62 is a member in which a plurality of radiators 63 are arranged, and the radiator 63 is provided with a plurality of plate-shaped fins 64 extending in parallel from a base 66. Although the number of radiators 63 can be set appropriately, in the present embodiment, a total of four radiators 63 are arranged, wherein two radiators are arranged in the longitudinal direction and two radiators are arranged in the transverse direction. In addition, a long groove 66G matching the outer diameter of the refrigerant pipe 72 is formed on the back side 66B of the base 66 of the radiator 63.

[0041] like Figure 3 As shown, the block 68 is a solid block-shaped block that is roughly rectangular. Figure 2 and Figure 3As shown, when viewed from the front, the size of the block 68 is the same as the size of a plurality of radiators 63 combined on a plane. In addition, the block 68 is formed with a long groove 68G on one side of the surface 68F to match the outer diameter of the refrigerant tube 72. In addition, in the present disclosure, a solid block refers to a state in which, from a macroscopic point of view, no space is formed inside the component and the volume of the material forming the component is approximately equal to the volume of the component. In other words, in the present disclosure, it can be said that from a macroscopic point of view, the block 68 has a uniform cross section.

[0042] The refrigerant pipe 72 is a pipe body that allows the refrigerant to circulate inside, similarly to the refrigerant pipe 32 disposed in the machine room 30, and provides the cooling energy of the refrigerant flowing inside to the heat exchange member 62 and the block 68. In addition, the refrigerant pipe 72 may be a member that is integral with the refrigerant pipe 32 as long as it can allow the refrigerant to circulate inside together with the refrigerant pipe 32 disposed in the machine room 30, or may be a separate body from the refrigerant pipe 32 and formed in a manner that the pipe bodies are connected to each other.

[0043] In this embodiment, if Figure 1 and Figure 3 As shown, the heat exchange member 62 and the block 68 sandwich the refrigerant pipe 72 to achieve thermal integration. In addition, in this embodiment, although the heat exchange member 62 and the block 68 can be integrated in any way, as an example, the heat exchange member 62 and the block 68 are fastened using fasteners such as screws not shown.

[0044] In the present embodiment, the refrigerant pipe 72 is closely attached to the long groove 66G of the heat exchange member 62 and the long groove 68G of the block 68 when the heat exchange member 62 and the block 68 are integrated.

[0045] In addition, in this embodiment, if Figure 1 As shown, the thermal storage energy component 60 is arranged in the cold air passage 50 to be separated from the partition wall 12. In other words, in the present embodiment, a gap 70 is formed between the thermal storage energy component 60 and the wall of the cold air passage 50. In addition, in the present embodiment, the gap 70 is also a part of the air passage through which the cold air in the cold air passage 50 flows. In addition, in the present embodiment, as an example of a method of separating the thermal storage energy component 60 from the partition wall 12, a pair of fixing plates 74 opposite to each other in the width direction and formed with a step protruding forward and installed on the partition wall 12 are fixed by screws 76. By fixing the edge portions on both sides of the width direction of the thermal storage energy component 60 to the step portions of the fixing plates 74, a gap 70 of a length protruding from the step of the fixing plates 74 is formed between the thermal storage energy component 60 and the partition wall 12.

[0046] In addition, if Figure 1 and Figure 2 As shown, in this embodiment, the heat sink 63 is configured such that the fins 64 are arranged along the direction of the air flow in the cold air passage 50 ( Figure 1 and Figure 2 The figure (in the upper and lower directions) extends.

[0047] In the present disclosure, the thermal storage energy member 60 may be made of any material as long as it has a heat capacity and thermal conductivity sufficient to store and release cold energy, but is formed of aluminum as an example.

[0048] In the present disclosure, the thermal energy storage member 60 may have any shape as long as it has a heat capacity and thermal conductivity that can store and release cold energy. As an example, a surface area of ​​0.1 m2 per 1 kg weight is used. 2 The shape is as follows, and more than 80% of the surface area is exposed to the cold air (the air in the cold air duct 50).

[0049] Next, the operation of the refrigerator 10 in the present embodiment will be described. In the following description, cold energy is previously stored in the thermal storage member 60 (the thermal storage member 60 is cooled).

[0050] (Rapid freezing operation mode)

[0051] When the freezing object 26 is put into the freezing chamber 20 and the temperature in the freezing chamber 20 exceeds the preset temperature, the controller (not shown) switches the operation state to the rapid freezing operation mode. In the rapid cooling operation mode, the fan 54 is driven to rotate so that the air in the cold air passage 50 and the freezing chamber 20 circulates, and the air in the freezing chamber 20 heated by the freezing object 26 is sucked into the cold air passage 50 from the suction port 56 and cooled by the thermal storage energy member 60. The cooled air is supplied to the freezing chamber 20 again from the blow-out port 58 to cool the freezing object 26. In other words, the rapid freezing operation mode can also be said to be an operation mode in which the cold energy stored in the thermal storage energy member 60 is released.

[0052] (Temperature maintenance operation mode)

[0053] When the freezing object 26 is cooled by the rapid freezing operation and the temperature in the freezing chamber 20 is lower than a preset temperature, the controller (not shown) switches the operation state to the temperature maintenance operation mode. In the temperature maintenance operation mode, as long as the temperature in the freezing chamber 20 is lower than a preset temperature, the rotation speed of the fan 54 is lower than that in the rapid freezing operation mode.

[0054] In addition, in any of the rapid operation mode and the temperature maintenance operation mode, the temperature of the refrigerant flowing in the refrigerant pipe 72 in thermal contact with the thermal storage energy member 60 is lower than the temperature of the thermal storage energy member 60. Therefore, during the temperature maintenance operation mode, the thermal storage energy member 60 stores the cold energy released in the rapid freezing operation mode again. In other words, the temperature maintenance operation mode can also be said to be a mode of operation in which cold energy is stored in the thermal storage energy member 60.

[0055] Then, the cold energy stored in the thermal storage member 60 during the temperature maintenance operation mode is released when a new freezing object 26 is introduced into the freezing chamber 20 and a controller (not shown) switches the operation state to the rapid freezing operation mode.

[0056] In addition, the preset temperature at which the controller switches the operating state in the above description and not shown can be appropriately set according to the capacity of the freezer, etc. In addition, the controller not shown can also switch the operating state based on the temperature of the frozen object 26 instead of switching the operating state based on the temperature of the freezing chamber 20.

[0057] Next, the operation and effects of the refrigerator 10 of the present disclosure will be described.

[0058] (Function and Effect)

[0059] According to the refrigerator 10 of this embodiment, a thermal storage member 60 is arranged in the cold air passage 50. Cold energy is provided through the refrigerant pipe and stored in the thermal storage member 60. When rapid freezing is performed, the rotation speed of the fan 54 is increased, the air of the freezing chamber 20 is sucked in from the suction port 56 of the cold air passage 50, contacts the thermal storage member 60, and the cold air is blown out from the blowing port 58 to the freezing chamber 20.

[0060] Thus, by using the cold energy stored in the thermal storage member 60 , the frozen objects 26 accommodated in the freezing chamber 20 can be rapidly frozen in a short time and with low power consumption compared to the refrigerator 10 without the thermal storage member 60 in the cold air passage 50 .

[0061] In addition, according to the refrigerator 10 of the present embodiment, the thermal storage energy member 60 is formed by thermally integrating the heat exchange member 62 having a plurality of fins 64 with the solid block 68. Therefore, compared with a simple block-shaped thermal storage energy member 60, cold energy can be stored, and a large amount of cold energy can be released through the heat exchange member 62.

[0062] Furthermore, according to the refrigerator 10 of the present embodiment, the refrigerant pipe 72 is buried in the thermal energy storage member 60 , thereby improving the energy storage effect.

[0063] Furthermore, according to the refrigerator 10 of the present embodiment, the heat exchange member 62 is a plurality of radiators 63 having long grooves 66G formed on the back surface 66B in which the refrigerant tubes 72 are embedded. Furthermore, the heat capacity member is a block 68 having the same size as the size of the plurality of radiators 63 combined on a plane, the heat capacity member having long grooves 68G formed therein, overlapping the back surface 66B, and burying the refrigerant tubes 72 together with the plurality of radiators 63. Thus, in the refrigerator 10 of the present embodiment, the refrigerant tubes 72 are buried using the plurality of radiators 63 and the block 68, thereby promoting heat exchange between the refrigerant tubes 72 and the thermal storage energy member 60. Furthermore, by separating the overlapping heat exchange member 62 and the block 68, the refrigerant tubes 72 can be easily replaced.

[0064] In addition, according to the refrigerator 10 of this embodiment, the cold air flows between the fins 64, so the contact area of ​​the cold air becomes larger and the heat exchange rate is improved. In addition, the flow of the cold air is not hindered, and the flow rate of the cold air is not reduced due to the generation of eddy currents.

[0065] Furthermore, according to the refrigerator 10 of this embodiment, the gap 70 between the thermal storage member and the wall is also used as an air passage, so that the contact area between the thermal storage member and the wind is increased, thereby improving the heat exchange rate of the thermal storage member.

[0066] In addition, according to the refrigerator 10 of this embodiment, by using the heat storage member 60 as an aluminum member, the thermal conductivity and heat dissipation are improved, thereby improving the energy storage efficiency and heat exchange rate. In addition, by setting the surface area per 1 kg weight of the aluminum member to 0.1 m 2 The surface area is set to be more than 80% exposed to the cold wind, thereby improving the energy storage / heat dissipation efficiency. In addition, the aluminum component is processed to a surface area of ​​0.1m per 1kg weight. 2 As described above, the thermal storage member can be made lighter and the material cost can be reduced. In addition, it can be set so that 80% or more of the surface area of ​​the thermal storage member is exposed to the cold wind.

[0067] In addition, according to the refrigerator 10 of the present disclosure, since the thermal storage energy member 60 stores cold energy, rapid freezing can be performed even if the electric capacity of the compressor is small. Therefore, according to the refrigerator 10 of the present disclosure, since the thermal storage energy member 60 stores cold energy, the power consumption of the refrigerator 10 as a whole can be reduced compared with the refrigerator 10 without the thermal storage energy member 60.

[0068] Next, refer to Figure 4 , the results of a comparative experiment of cooling a frozen object 26 using a refrigerator 10 of an embodiment (a refrigerator 10 having the thermal storage energy member 60 of the present disclosure) and a refrigerator of a comparative example (a refrigerator not having the thermal storage energy member 60 of the present disclosure) will be described.

[0069] (Comparative Experiment)

[0070] In this comparative experiment, the freezing object 26 was set to a 300 g instant rice bag, and the time required until the freezing object 26 was frozen was compared. In addition, the freezing object 26 was 98°C at the start of freezing, and the time when the temperature began to drop again after balancing at around 0°C for a period of time was regarded as the end of freezing. In addition, in this comparative experiment, the temperature of the freezing object 26 was measured.

[0071] In addition, the volume of the freezer compartment 20 and the cold air duct 50 in the freezer 10 of the embodiment and the freezer of the comparative example is 40 L. In addition, the power consumption in the rapid operation mode in the freezer 10 of the embodiment and the freezer 10 of the comparative example is 80 W, and the refrigeration capacity is 160 W (the coefficient of refrigeration (COP) is 2).

[0072] In addition, the block 68 and the heat exchange member 62 in the heat storage member 60 of the refrigerator 10 of the embodiment are aluminum members formed of aluminum as the main material. In this embodiment, in the heat storage member 60, the weight of each radiator 63 is set to 2 kg, the weight of the block 68 is set to 2 kg, and the total weight is 4 kg. In addition, with respect to the radiator 63, the thickness of the fin 64 is set to 2 mm, the length of the fin 64 is set to 30 mm, and the number of fins 64 is set to 9, so that the surface area per 1 kg weight of the heat storage member 60 is 0.1 m 2 The shape has a surface area of ​​more than 80% exposed to cold wind.

[0073] The other conditions of the refrigerator 10 of the embodiment and the refrigerator of the comparative example are the same. In other words, the refrigerator 10 of the embodiment is different from the refrigerator of the comparative example in that the refrigerator 10 has the thermal energy storage member 60 .

[0074] Furthermore, the refrigerator 10 of the embodiment has already accumulated cold energy in advance at the start of freezing the freezing target 26 .

[0075] Figure 4 (A) is a refrigerator of a comparative example. Figure 4 As shown in (A), in the refrigerator 10 of the comparative example, the object to be frozen 26 was frozen 276 minutes after being put into the freezing chamber 20 (the temperature of the object to be frozen 26 was lower than 0°C).

[0076] Figure 4 (B) is a refrigerator 10 of the embodiment. Figure 4 As shown in (B), in the freezer 10 of the embodiment, the frozen object 26 is frozen 56 minutes after being put into the freezing chamber 20 (the temperature of the frozen object 26 is lower than 0°C). Figure 4It can be seen that the refrigerator 10 of the embodiment can rapidly freeze food in a short time, and does not deteriorate the quality of the food, compared with the refrigerator of the comparative example.

[0077] Furthermore, in general, in order to rapidly freeze the frozen object 26, the temperature of the cold air circulating in the freezing chamber 20 and the cold air passage 50 is lowered and the air volume is increased, and therefore, it is necessary to increase the size of the compressor 34 and other devices. In other words, in the freezer 10 in which the compressor 34 and other devices are increased, the power consumption (the amount of electricity used per unit time) of the freezer 10 increases.

[0078] Here, if Figure 4 As shown in (B), the refrigerator 10 of the embodiment can rapidly freeze the frozen object 26 by accumulating cold energy over 120 minutes as the cold storage time after the frozen object 26 is frozen. Figure 4 It can be seen that the refrigerator 10 of the embodiment can reduce the power consumption of the refrigerator 10 as a whole, compared with the refrigerator 10 of the comparative example.

[0079] (Variation Example)

[0080] In the above description, the gap 70 is formed between the thermal storage member 60 and the partition wall 12 of the cold air passage 50 , but the refrigerator 10 of the present disclosure is not limited thereto.

[0081] In addition, although the fins 64 extend along the flow of the cold air in the above description, the refrigerator 10 of the present disclosure is not limited thereto. That is, the fins 64 may extend in a direction intersecting the flow of the cold air.

[0082] In addition, although in the above description, the heat storage member 60 is a heat exchange member 62 formed by arranging a plurality of radiators 63 having long grooves 66G, and a block 68 having long grooves 68G, the refrigerator 10 of the present disclosure is not limited thereto. For example, the refrigerant pipe 72 may also be buried in either the heat exchange member 62 or the block 68.

[0083] In addition, although in the above description, the refrigerant pipe 72 is buried in the thermal storage member 60, the refrigerator 10 of the present disclosure is not limited thereto. For example, the refrigerant pipe 72 may be attached to the thermal storage member 60 using tape or the like to achieve thermal integration.

[0084] The embodiments of the present disclosure are described above with reference to the accompanying drawings, but it should be understood that a person having ordinary knowledge in the technical field to which the present disclosure belongs can obviously think of various variations or applications within the scope of the technical ideas described in the scope of the claims, and these naturally also belong to the technical scope of the present disclosure.
