[0018] (Insights, etc., that form the basis of this invention)

[0019] When the inventors conceived of this invention, there was already a technique for placing a rectangular frame-shaped (square frame-shaped) mounting component, which houses a cooling fan and a condenser, on the bottom surface of the machine room of a cold storage unit adjacent to the compressor.

[0020] However, in existing technologies, the cooling fan and condenser are fixed to the mounting components, resulting in time-consuming and labor-intensive replacement and assembly operations for either the cooling fan or the condenser. Furthermore, the inventors discovered that because the mounting portion of the condenser in the mounting components is approximately quadrilateral and the mounting portion of the cooling fan is approximately circular, the airflow resistance through the condenser increases when the cooling fan is activated, thus posing a risk of requiring a larger cooling fan. The present invention was developed to address this problem.

[0021] The present invention provides a cold storage that allows for easy replacement and assembly of the fan and condenser, and improves the efficiency of heat exchange by the condenser even when using a smaller fan.

[0022] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. However, there are cases where detailed descriptions that are more than necessary are omitted. For example, there are cases where detailed descriptions of matters that are already known are omitted or where substantially the same structure is described repeatedly.

[0023] Furthermore, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the invention, and are not intended to limit the subject matter described in the claims.

[0026] [1-1. Structure]

[0027] [1-1-1. Structure of a Cold Storage]

[0028] Figure 1 This is a side sectional view of the cold storage in Implementation Method 1. Figure 2 This is a front sectional view of the cold storage in Implementation Method 1.

[0029] In this instruction manual, when weighing the front, back, left, and right sides of the cold storage unit 1, the following steps are used: Figure 1, Figure 2 As a benchmark. That is, based on Figure 1 The left and right sides correspond to the front and back of cold storage 1 for explanation. Furthermore, using... Figure 2 The left and right sides are described in relation to the left and right sides when viewed from the front of the cold storage 1. Additionally, the front surface of the cold storage 1 is sometimes referred to as the front view. Furthermore, the rear surface of the cold storage 1 is sometimes referred to as the back view.

[0030] like Figure 1 As shown, the cold storage 1 includes a box-shaped shell 10 with an open front surface. A machine compartment 4 is located behind the upper surface of the shell 10. A compressor 5 is installed in the machine compartment 4.

[0031] A cold storage compartment 11 with a temperature of about 2°C to 4°C is formed above the shell 10, and a first freezer compartment 12 and a second freezer compartment 13 with a temperature of about -18°C are formed below the shell 10.

[0033] Insulated partition walls 15 are provided between the refrigerator compartment 11 and the first freezer compartment 12, between the first freezer compartment 12 and the second freezer compartment 13, and between the second freezer compartment 13 and the vegetable compartment 14.

[0034] In addition, the first freezer compartment 12 can also be used as a freezer, a micro-freezing compartment or a refrigerator compartment by switching on and off.

[0035] A micro-freezing chamber 16, serving as a storage chamber, is provided below the interior of the cold storage chamber 11.

[0036] In the cold storage 1, a rotating door 17 is provided at the opening on the front surface of the cold storage compartment 11, which can be opened and closed freely.

[0040] like Figure 1As shown, a refrigeration pipe 24 is provided on the rear side of the refrigeration compartment 11 of the cold storage 1. The refrigeration compartment 11 and the refrigeration pipe 24 are separated by a first partition plate 31.

[0042] Cooling chambers 26 are provided on the rear side of the first freezer compartment 12 and the second freezer compartment 13 of the cold storage 1.

[0045] [1-1-2. Structure of the machine room]

[0046] Next, the structure of the machine room will be explained.

[0047] Figure 2 This is a perspective view of the machine room portion in Embodiment 1, viewed from the rear left side. Figure 3 This is a perspective view of the machine room portion in Embodiment 1, viewed from the rear right side. Figure 4 This is an exploded perspective view of the condenser unit in Embodiment 1. Figure 5 This is a longitudinal sectional view of the condenser unit in Embodiment 1. Figure 6 This is a front view of the condenser unit in Embodiment 1, viewed from the condenser side.

[0048] like Figure 2 and Figure 3 As shown, the machine room 4 is located at the upper rear of the housing 10. The upper surface and the back surface of the machine room 4 are open.

[0049] A compressor 5 is installed in the machine room 4. A condenser unit 40 for mounting a condenser 6 is located near one side of the compressor 5.

[0050] like Figures 4 to 6 As shown, the condenser unit 40 includes a four-sided, frame-shaped box component (frame component) 41. The shape of the box component 41 is formed to be approximately the same as the internal shape of the machine chamber 4.

[0051] A condenser mounting frame 42 is formed on one side of the box component 41.

[0052] The condenser mounting frame 42 is shaped to be approximately the same size as the condenser 6.

[0053] The condenser mounting frame 42 has condenser retaining claws 43 on its upper and lower edges for holding the condenser 6. The condenser retaining claws 43 are configured such that their front ends can deform in the vertical direction.

[0054] The condenser 6 consists of flat tubes 50 that are formed in a meandering shape and serrated ("zigzag") fins 51 arranged between each flat tube 50.

[0055] Two manifolds 52, which conduct refrigerant to the flat tube 50, are connected to the upper and lower corners of the condenser 6.

[0056] Two headers 52 extend toward the opposite side of the compressor 5 of the condenser 6 and connect to the specified refrigerant piping.

[0057] A fan mounting frame 44 is provided on the other side of the box component 41.

[0058] The fan mounting frame 44 is smaller than the condenser mounting frame 42. An inclined surface 45 is formed between the fan mounting frame 44 and the condenser mounting frame 42 to make the condenser mounting frame 42 and the fan mounting frame 44 continuous.

[0059] Fan mounting frame 44 has fan retaining claws 46 on its upper and lower edges for holding the fan 7. The fan retaining claws 46 are configured such that their front ends can deform in the vertical direction.

[0060] As described above, the four-sided box component 41 is shaped to be approximately the same as the internal shape of the machine chamber 4. Therefore, when the machine chamber 4 is equipped with the box component 41, the compressor 5 and the condenser 6 are separated by the box component 41 inside the machine chamber 4.

[0061] By dividing the interior of the machine chamber 4 using the box component 41, air is drawn from the outside of the cold storage casing 10 into the interior of the machine chamber 4 when the fan 7 is driven. After passing through the fins 51 of the condenser 6, it is guided to the inclined surface 45 and blown out from the fan 7 towards the compressor 5. That is, all the air drawn into the machine chamber 4 passes through the condenser 6, enabling efficient heat exchange within the condenser 6.

[0062] In addition, a dryer 60 for removing moisture from the refrigerant is installed on the side of the condenser 6 in the machine room 4.

[0063] Therefore, in this embodiment, the compressor 5, condenser 6, and dryer 60 are arranged in the order of compressor 5, condenser 6, and dryer 60 inside the machine room 4. That is, the compressor 5, condenser 6, and dryer 60 are arranged in order of decreasing temperature.

[0064] As a result, the compressor 5 is heated by driving the compressor 5, and the temperature around the compressor 5 also rises. However, the air passing through the condenser 6 becomes at approximately the same temperature as the outside temperature of the casing 10, thus improving the heat exchange efficiency in the condenser 6.

[0065] like Figure 6 As shown, a cover component 70 covering the upper surface and back of the machine room 4 is installed at the upper rear of the housing 10. The cover component 70 is formed with a cross-sectional shape that is approximately L-shaped.

[0066] A soft foam component 71 is attached to the inner surface of the cover component 70. The foam component 71 is disposed in the inner surface of the cover component 70 at a position corresponding to the shape of the box component 41.

[0067] Therefore, when the cover component 70 of the machine chamber 4 is closed, the foam component 71 can abut against the upper surface and the side of the back side of the box component 41. Thus, when the cover component 70 is closed, the gap between the cover component 70 and the box component 41 can be sealed by the foam component 71, and the compressor 5 and the condenser 6 can be completely separated inside the machine chamber 4 by the box component 41.

[0068] [1-2. Actions, etc.]

[0069] Next, the operation of the cold storage 1 in Implementation Method 1 will be explained.

[0070] In this embodiment, by driving the compressor 55 to deliver refrigerant to the refrigerant circuit, the refrigerant that has undergone heat exchange in the condenser 6 is circulated to the cooler 27, thereby cooling the cooler 27.

[0071] Then, by driving the air supply fan 30, cold air cooled by the cooler 27 is delivered into the storage room to cool the cold storage compartment 11, the first freezer compartment 12, the second freezer compartment 13, the vegetable compartment 14, or the micro-freezing compartment 16.

[0072] In this embodiment, an inclined surface 45 is formed between the fan mounting frame 44 and the condenser mounting frame 42, making the condenser mounting frame 42 and the fan mounting frame 44 continuous. Therefore, when air is delivered from the condenser 6 to the compressor 5 by driving the fan 7, the resistance of the air passing through the condenser 6 can be reduced by utilizing the inclined surface 45. Thus, even when using a small fan 7, the heat exchange performed by the condenser 6 can be carried out efficiently.

[0073] Here, a refrigeration cycle loop consisting of a compressor 5, a condenser 6, and a cooler 27 is installed in the cold storage 1. The refrigeration cycle loop is connected via refrigerant piping, forming a refrigerant circulation path. Furthermore, in conventional cold storage facilities, there is a technology that installs heat dissipation pipes in the refrigeration cycle loop to cool the refrigerant.

[0074] However, in this embodiment, the efficiency of heat exchange performed by the condenser 6 can be improved, and the efficiency of cooling performed by the condenser 6 can be improved. Therefore, heat dissipation pipes are no longer needed, and the cold storage 1 can be cooled without the use of heat dissipation pipes.

[0075] Furthermore, with the housing component 41 installed in the machine chamber 4, the compressor 5 and the condenser 6 are separated inside the machine chamber 4 by the housing component 41, and when the cover component 70 is closed, the gap between the cover component 70 and the housing component 41 can be sealed by the foam component 71. Therefore, when the fan 7 is driven, all the air drawn into the machine chamber 4 can pass through the condenser 6, enabling efficient heat exchange in the condenser 6.

[0076] Furthermore, inside the machine compartment 4, the compressor 5, condenser 6, and dryer 60 are arranged in descending order of temperature. Therefore, air with a temperature approximately the same as the external temperature of the casing 10 passes through the condenser 6, which improves the heat exchange efficiency within the condenser 6. Additionally, the compressor 5 can be efficiently cooled using the air passing through the condenser 6.

[0077] Furthermore, when installing the condenser 6 into the condenser unit 40, the condenser 6 can be fixed to the condenser mounting frame 42 by inserting the condenser 6 into the inside of the condenser mounting frame 42 and engaging the condenser retaining claws 43 with the upper and lower edges of the condenser 6. Moreover, by deforming the condenser retaining claws 43 outwards from the condenser 6 to release the engagement, the condenser 6 can be easily removed from the condenser mounting frame 42.

[0078] Similarly, when installing the fan 7 on the condenser unit 40, the fan 7 can be fixed to the fan mounting frame 44 by inserting the fan 7 into the inside of the fan mounting frame 44 and engaging the fan retaining claw 46 with the upper and lower edges of the fan 7. Furthermore, the fan 7 can be easily removed from the fan mounting frame 44 by deforming the fan retaining claw 46 outwards to release the engagement of the fan retaining claw 46.

[0079] In this way, the condenser 6 and fan 7 can be easily installed and removed from the box component 41, thus enabling easy assembly and replacement of the condenser 6 and fan 7.

[0080] [1-3. Effects, etc.]

[0081] As described above, the cold storage 1 of this embodiment includes a mechanical room 4 inside the shell 10. The compressor 5 and the condenser unit 40 are housed inside the mechanical room 4. The condenser unit 40 is composed of a box component 41 with a generally four-sided frame shape and a fan 7 and a condenser 6 integrally mounted on the box component 41.

[0082] Therefore, the fan 7 and the condenser 6 are integrated into the box component 41 and modularized, making it easy to assemble and replace the fan 7 or the condenser 6.

[0083] Furthermore, in the cold storage 1 of this embodiment, a fan 7 is installed from one side of the box component 41, and a condenser 6 is installed from the other side of the box component 41.

[0084] Therefore, since the fan 7 and the condenser 6 are integrally mounted in the box component 41 and are modularized, the fan 7 or the condenser 6 can be easily assembled and replaced.

[0085] Furthermore, in the cold storage 1 of this embodiment, the condenser 6 includes a manifold 52 for conducting refrigerant to the condenser 6. The manifold 52 is located at the corner of the condenser 6 and is located on the opposite side of the fan 7 of the condenser 6.

[0086] Therefore, since the manifold 52 extends to the opposite side of the fan 7 of the condenser 6, the box component 41 will not be an obstacle when connecting the refrigerant piping to the condenser 6, and the connection of the refrigerant piping can be carried out easily.

[0087] Furthermore, in the cold storage 1 of this embodiment, the box component 41 includes a condenser mounting frame 42 for mounting the condenser 6 and a fan mounting frame 44 for mounting the fan 7, and an inclined surface 45 is formed between the condenser mounting frame 42 and the fan mounting frame 44 to make the condenser mounting frame 42 and the fan mounting frame 44 continuous.

[0088] Therefore, when air is delivered from the condenser 6 to the compressor 5 by driving the fan 7, the resistance of the air passing through the condenser 6 can be reduced by utilizing the inclined surface 45. Thus, even when using a smaller fan 7, the heat exchange carried out by the condenser 6 can be performed efficiently.

[0089] Furthermore, in the cold storage 1 of this embodiment, a condenser fixing claw 43 for fixing the condenser 6 is provided in the condenser mounting frame 42 of the box component 41, and a fan fixing claw 46 for fixing the fan 7 is provided in the fan mounting frame 44 of the box component 41.

[0090] Therefore, since the condenser 6 is fixed to the condenser mounting frame 42 by the condenser fixing claw 43 and the fan 7 is fixed to the fan mounting frame 44 by the fan fixing claw 46, the fan 7 or the condenser 6 can be easily assembled and replaced.

[0091] Furthermore, in the cold storage 1 of this embodiment, the compressor 5 and the condenser 6 are separated by a box component 41 inside the machine room 4.

[0092] Therefore, by using the box component 41 to divide the interior of the machine chamber 4, all the air taken into the machine chamber 4 can pass through the condenser 6, and heat exchange in the condenser 6 can be carried out efficiently.

[0093] Furthermore, in the cold storage 1 of this embodiment, a dryer 60 is housed in the machine room 4, and a compressor 5, a condenser 6, and a dryer 60 are arranged in sequence inside the machine room 4. The fan 7 is configured to deliver air from the condenser 6 side to the compressor 5 side.

[0094] Therefore, the compressor 5, condenser 6, and dryer 60 are arranged in order of temperature from high to low, and air is delivered from the condenser 6 side to the compressor 5 side by the fan 7. Thus, even when the temperature around the compressor 5 rises due to the drive of the compressor 5, the air passing through the condenser 6 becomes approximately the same temperature as the outside temperature of the casing 10. Therefore, the heat exchange efficiency in the condenser 6 can be improved.

[0095] Furthermore, in the cold storage 1 of this embodiment, the shell 10 includes a cover component 70 that covers the machine room 4, and a foam component 71 that abuts against the outer surface of the box component 41 is provided on the inner surface of the cover component 70.

[0096] Therefore, when the cover component 70 of the machine chamber 4 is closed, the foam component 71 can abut against the outer surface of the box component 41. Thus, when the cover component 70 is closed, the foam component 71 can seal the gap between the cover component 70 and the box component 41, and the box component 41 can completely separate the compressor 5 and the condenser 6 inside the machine chamber 4. Therefore, all air drawn into the machine chamber 4 can pass through the condenser 6, enabling efficient heat exchange in the condenser 6.

[0097] (Other implementation methods)

[0098] Furthermore, Embodiment 1 has been described as an example of the technology disclosed in this application. However, the technology of the present invention is not limited thereto, and can also be applied to embodiments with modifications, substitutions, additions, omissions, etc.

[0099] In Embodiment 1, an example is shown where the machine compartment 4 is located at the upper rear of the shell 10 of the cold storage, but the present invention is not limited thereto. For example, the present invention can be applied even when the machine compartment 4 is located at the lower rear of the cold storage, and the same effect as in Embodiment 1 can be obtained.

[0100] (Postscript)

[0101] The following technology is disclosed through the description of the above embodiments.

[0102] (Technology 1) A cold storage unit includes a mechanical room inside the shell, wherein a compressor and a condenser unit are housed inside the mechanical room, the condenser unit consisting of a generally four-sided box component and a fan and a condenser integrally mounted on the box component.

[0103] Because the fan and condenser are integrated into a single unit and modularized, the fan or condenser can be easily assembled and replaced.

[0104] (Technology 2) The cold storage as described in Technology 1, wherein the fan is installed from one side of the box component and the condenser is installed from the other side of the box component.

[0105] Because the fan and condenser are integrated into a single unit and modularized, the fan or condenser can be easily assembled and replaced.

[0106] (Technology 3) The cold storage as described in Technology 1 or Technology 2, wherein the condenser includes a manifold for conducting refrigerant to the condenser, the manifold being disposed at a corner of the condenser and extending toward the side of the condenser opposite to the fan.

[0107] Because of this structure, the manifold extends to the opposite side of the condenser fan, so the box components do not become an obstacle when connecting the refrigerant piping to the condenser, making the refrigerant piping connection work easy.

[0108] (Technology 4) The cold storage as described in any one of Technologies 1 to 3, wherein the box component includes a condenser mounting frame for mounting the condenser and a fan mounting frame for mounting the fan, and an inclined surface is formed between the condenser mounting frame and the fan mounting frame to make the condenser mounting frame and the fan mounting frame continuous (connected).

[0109] According to this structure, when air is delivered from the condenser to the compressor by driving a fan, the inclined surface reduces the resistance of the air passing through the condenser. Therefore, even when using a smaller fan, the heat exchange that occurs in the condenser can be carried out efficiently.

[0110] (Technology 5) The cold storage as described in Technology 4, wherein the condenser mounting frame of the box component is provided with a condenser fixing claw for fixing the condenser, and the fan mounting frame of the box component is provided with a fan fixing claw for fixing the fan.

[0111] According to this structure, since the condenser is fixed to the condenser mounting frame using condenser mounting claws and the fan is fixed to the fan mounting frame using fan mounting claws, the assembly and replacement of the fan or condenser can be easily performed.

[0112] (Technology 6) A cold storage room as described in any one of Technologies 1 to 5, wherein the compressor and the condenser are separated inside the machine room by the box component.

[0113] According to this structure, by using the box component to divide the interior of the machine room, all the air taken into the machine room can pass through the condenser, enabling efficient heat exchange in the condenser.

[0115] According to this structure, the compressor, condenser, and dryer are arranged in order of temperature from high to low, and a fan is used to deliver air from the condenser side to the compressor side. Thus, even when the temperature around the compressor rises due to the compressor's drive, the air passing through the condenser becomes approximately the same temperature as the outside temperature of the casing, thereby improving the heat exchange efficiency in the condenser.

[0116] (Technology 8) The cold storage as described in any one of Technologies 1 to 7, wherein the housing includes a cover member covering the machine room, and a foam member is provided on the inner surface of the cover member to abut against the outer surface of the box member.

[0117] According to this structure, when the cover component of the machine chamber is closed, the foam component can abut against the outer surface of the box component. Therefore, when the cover component is closed, the gap between the cover component and the box component can be sealed with the foam component, and the interior of the machine chamber can be completely separated from the compressor and condenser inside the machine chamber by the box component. Therefore, all air drawn into the machine chamber can pass through the condenser, enabling efficient heat exchange in the condenser.
