Description

Technology Field

[0001] The present invention relates to a method for manufacturing freezing and refrigeration equipment, and more specifically, to a method for manufacturing freezing and refrigeration equipment in which a cooler and a fan are installed in the freezer and the refrigerator, respectively, to enable individual control of the freezer and the freezer, to prevent cold air loss by improving the thermal insulation performance of the opening and closing door, and to improve convenience of use by enabling forward, backward, lifting, and angle adjustment of the freezing and refrigeration equipment. Background Technology

[0003] Generally, refrigeration equipment is configured with a refrigerator body having an insulated structure that forms a freezer compartment and a refrigerator compartment partitioned by an intermediate partition, and with a freezer door and a refrigerator door installed therein.

[0004] The compressor, condenser, pressure reducer, and cooler, which are components for performing the refrigeration cycle, are connected in sequence by refrigerant pipes to form a closed circuit.

[0005] Such refrigeration equipment performs a refrigeration cycle by exchanging heat through the state change of the refrigerant passing through refrigerant pipes and refrigeration cycle components, and specifically generates cold air by absorbing heat from the surroundings through the evaporation of the refrigerant in the cooler.

[0006] The compressor is installed on the lower side of the main body, and the cooler is installed on the rear wall of the freezer.

[0007] A cooling fan is installed on the upper side of the cooler, and a fan guide and a cold air duct, each having a cold air outlet formed in front of the cooling fan and on the rear wall of the refrigerator compartment, are installed, respectively.

[0008] A portion of the cold air, which has undergone heat exchange while passing through the cooler, is supplied to the freezer room through the cold air outlet of the fan guide, and the remaining portion is supplied to the refrigerator room through the cold air outlet of the cold air duct. To return the cold air supplied to each room, a first return path and a second return path are formed in the intermediate partition, respectively.

[0009] Looking at conventional refrigerator control methods, first, to determine whether to turn the compressor on or off, the temperature of the freezer is detected, and a judgment is made by comparing the freezer temperature with a predetermined freezer set temperature that is appropriate for freezing food.

[0010] When making a comparison, if the freezer temperature is higher than the freezer set temperature, the compressor and cooling fan are turned on; if the freezer temperature is lower than the freezer set temperature, the compressor and cooling fan are turned off. Subsequently, the refrigerator temperature is compared with the refrigerator set temperature, which is predetermined as the appropriate temperature for refrigerated food storage; if the refrigerator temperature is higher than the refrigerator set temperature, the control damper is opened, and if the refrigerator temperature is lower than the refrigerator set temperature, the control damper is closed.

[0011] However, conventional refrigeration equipment has a problem in that it is difficult to maintain the freshness of food due to the poor insulation of the freezer and refrigerator doors.

[0012] In addition, since conventional refrigeration equipment is of the floating type, there is the inconvenience of the user having to manually transport food to the refrigeration equipment. Prior art literature

[0028] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. Throughout the specification, similar parts are denoted by the same reference numerals.

[0029] FIG. 1 is a cross-sectional view illustrating a refrigerator manufactured by a method for manufacturing freezing and refrigeration equipment according to one embodiment of the present invention, and FIG. 2 is a diagram illustrating a housing, a rotating plate, a rotating shaft, a first gear, an additional housing, a motor, a forward and backward cylinder, a lifting plate, a support plate, and a lifting cylinder applied to a method for manufacturing freezing and refrigeration equipment according to one embodiment of the present invention.

[0030] A method (1) for manufacturing freezing and refrigeration equipment according to one embodiment of the present invention may include at least one of the following steps: a first step of manufacturing a main body (10) having a refrigerator room (11) and a freezer room (12); a second step of installing a first cooler (20) and a refrigerator fan (30) in the refrigerator room (11); a third step of installing a second cooler (40) and a freezer fan (50) in the freezer room (12); a fourth step of hinge-connecting a first opening / closing door (60) to the refrigerator room (11); and a fifth step of hinge-connecting a second opening / closing door (70) to the freezer room (12).

[0031] The first step is to manufacture a main body (10) having a refrigerator (11) and a freezer (12) that are partitioned from each other.

[0032] The refrigerator room (11) and the freezer room (12) may be partitioned in the up and down direction or in the left and right direction by a partition wall (13), and the drawing shows an example in which the refrigerator room (11) and the freezer room (12) are partitioned in the up and down direction. In addition, the refrigerator room (11) and the freezer room (12) may each be formed in at least one or more places in the main body (10).

[0033] One side of each refrigerator compartment (11) and freezer compartment (12) is open. Through the open part, food for freezing can be stored in the freezer compartment (12), and food for refrigeration can be stored in the refrigerator compartment (11).

[0034] In the refrigerator room (11) and freezer room (12), a plurality of trays (14) can be installed at regular intervals in the vertical direction.

[0035] Food can be stored in the refrigerator (11) and freezer (12) respectively by dividing them into upper and lower sections using a plurality of trays (14).

[0036] Additionally, components included in a standard refrigerator, such as lighting, may be further installed in each of the refrigerator room (11) and the freezer room (12).

[0037] The method of manufacturing the main body (10) having a refrigerator compartment (11) and a freezer compartment (12) is a commercially available technology in the refrigerator field, so a detailed description is omitted.

[0038] The second step is to install the first cooler (20) and the refrigerator fan (30) in the refrigerator room (11).

[0039] The first cooler (20) and the refrigerator fan (30) are installed on the rear wall of the refrigerator room (11) via bolts or screws.

[0040] The first cooler (20) is a cooler applied to a normal refrigerator and generates cold air necessary for refrigeration.

[0041] The refrigeration fan (30) is a refrigeration fan (30) applied to a conventional refrigerator, and circulates the cold air generated from the first cooler (20) to the refrigerator room (11).

[0042] These first coolers (20) and refrigerator fans (30) operate by receiving external power, just like a conventional refrigerator.

[0043] The third step is to install a second cooler (40) and a freezer fan (50) in the freezer (12).

[0044] The second cooler (40) and the refrigeration fan (50) are installed on the rear wall of the freezer (12) using bolts or screws.

[0045] The second cooler (40) is a cooler applied to a standard refrigerator and generates cold air required for freezing.

[0046] The freezer fan (50) is a freezer fan (50) applied to a conventional refrigerator and circulates the cold air generated from the second cooler (40) to the freezer room (12).

[0047] These second coolers (40) and cooling fans operate by receiving external power, just like a normal refrigerator.

[0048] In addition, the aforementioned first cooler (20) and refrigeration fan (30) can be installed in the refrigerator room (11) in the same manner as a conventional refrigerator, and the second cooler (40) and freezing fan (50) can be installed in the freezer room (12) in the same manner as a conventional refrigerator.

[0049] In addition, a compressor (2) applicable to a conventional refrigerator is installed on the lower side of the main body (10).

[0050] The fourth step is to hinge the first opening / closing door (60) to the refrigerator room (11).

[0051] The first opening / closing door (60) is configured to open or close the refrigerator room (11).

[0052] A handle (631) is installed on the outer surface of the first opening / closing door (60) so that the user can open and close it.

[0053] The user can open or close the first opening / closing door (60) by pulling or pushing the handle (631).

[0054] Magnets are installed at the edges of the front open portion of the refrigerator room (11) and the edges of the first opening / closing door (60), respectively, just like in a conventional refrigerator.

[0055] The magnets of the refrigerator compartment (11) and the magnets of the first opening / closing door (60) are formed to have opposite polarities. Therefore, when the first opening / closing door (60) is positioned at the front of the refrigerator compartment (11), the magnets are attached so that the first opening / closing door (60) maintains the state of closing the refrigerator compartment (11).

[0056] At this time, the first opening / closing door (60) can be installed on the main body (10) in the same way as a conventional refrigerator.

[0057] The fifth step is to hinge the second opening / closing door (70) to the freezer (12).

[0058] The second opening / closing door (70) is configured to open or close the freezer room (12).

[0059] A handle (731) is installed on the outer surface of the second opening / closing door (70) so that the user can open and close it.

[0060] The user can open or close the second opening / closing door (70) by pulling or pushing the handle (731).

[0061] Magnets are installed at the edges of the front open portion of the freezer (12) and the edges of the second opening / closing door (70), just like in a conventional refrigerator.

[0062] The magnets of the freezer (12) and the second opening / closing door (70) are formed to have opposite polarities. Therefore, when the second opening / closing door (70) is positioned at the front of the freezer (12), the magnets are attached so that the second opening / closing door (70) maintains the state of closing the freezer (12).

[0063] At this time, the second opening / closing door (70) can be installed on the main body (10) in the same way as a conventional refrigerator.

[0064] Meanwhile, the aforementioned first opening / closing door (60) may include at least one of the first door body part (61), the first insulation material (62), and the first finishing plate (63).

[0065] The first door body (61) is configured to be rotatably coupled to the refrigerator room (11) and can be formed in a box shape with one side open and an internal space formed.

[0066] The first insulation material (62) is filled into the internal space of the first door body part (61).

[0067] The first insulation material (62) can be made of expanded polyurethane.

[0068] The first insulation material (62) prevents cold air inside the refrigerator room (11) from leaking out to the outside, and prevents external heat from entering the refrigerator room (11), thereby maintaining the freshness of the food stored in the refrigerator room (11).

[0069] The first finishing plate (63) is attached to the front of the first door body part (61). The first finishing plate (63) seals the open part of the first door part while concealing the first insulation material (62).

[0070] And, the aforementioned handle (631) is installed on the outer surface of the first finishing plate (63).

[0071] For example, the aforementioned first insulating material (62) may be composed of two pairs.

[0072] One of the first insulation materials (62) is attached to the inner wall surface of the first door body part (61), and the other first insulation material (62) is attached to the first finishing plate (63).

[0073] As a result, a pair of first insulation materials (62) are spaced apart from each other at a certain distance.

[0074] And, a first heat conductive medium (80) is interposed between the first insulating material (62).

[0075] The first heat-conducting medium (80) can have both sides bonded to the first insulating material (62) through an adhesive.

[0076] The first heat conducting medium (80) absorbs and stores the cold air when the cold air from the refrigerator room (11) passes through the first insulation material (62) installed in the first door body (61). In addition, the first heat conducting medium (80) releases the absorbed heat toward the first insulation material (62) installed in the first door body (61).

[0077] By absorbing the cold air of the refrigerator room (11) through this first heat conduction medium (80), the leakage and loss of cold air can be prevented.

[0078] The second door body (71) is configured to be rotatably coupled to the cold room and can be formed in a box shape with one side open and an internal space formed.

[0079] The second insulation material (72) is filled into the internal space of the second door body part (71).

[0080] The second insulation material (72) can be made of expanded polyurethane.

[0081] The second insulation material (72) prevents cold air inside the freezer (12) from leaking out to the outside, and prevents external heat from entering the freezer (12), thereby maintaining the freshness of the food stored in the freezer (12).

[0082] The second finishing plate (73) is attached to the front of the second door body part (71). The second finishing plate (73) seals the open part of the second door part while concealing the second insulation material (72).

[0083] And, the aforementioned handle (731) is installed on the outer surface of the second finishing plate (73).

[0084] For example, the aforementioned second insulation material (72) consists of two pairs.

[0085] One of the second insulation materials (72) is attached to the inner wall surface of the second door body part (71), and the other second insulation material (72) is attached to the second finishing plate (73).

[0086] As a result, a pair of second insulation materials (72) are spaced apart from each other at a certain distance.

[0087] And, a second heat-conducting medium (90) is interposed between the second insulation material (72).

[0088] The second heat-conducting medium (90) can be bonded to the second insulating material (72) on both sides through an adhesive.

[0089] The second heat conduction medium (90) absorbs and stores the cold air when the cold air from the refrigerator room (11) passes through the second insulation material (72) installed in the second door body (71). In addition, the second heat conduction medium (90) releases the absorbed heat toward the second insulation material (72) installed in the second door body (71).

[0090] By absorbing the cold air of the refrigerator room (11) through this second heat conduction medium (90), the leakage and loss of cold air can be prevented.

[0091] Additionally, a method for manufacturing freezing and refrigeration equipment according to one embodiment of the present invention may further include at least one of the steps of manufacturing a housing (100), attaching a rotating plate (110) to the bottom surface of the freezing and refrigeration equipment (1), attaching a rotating shaft (120) to the rotating plate (110), manufacturing an additional housing (130), and sequentially installing a motor (140), a forward and backward cylinder (150), and a lifting cylinder (180) in the housing (100).

[0092] The housing (100) can be formed in a box shape with an open top surface and an internal space.

[0093] The housing (100) can be formed by combining a plurality of plates into a square box shape or by manufacturing it through a molding die.

[0094] A freezing and refrigeration equipment (1) manufactured by the method for manufacturing freezing and refrigeration equipment according to one embodiment of the present invention can be used in a home or in a factory that produces food such as kimchi.

[0095] When the freezing and refrigeration equipment (1) manufactured by the method for manufacturing freezing and refrigeration equipment according to one embodiment of the present invention is used in a home, the housing (100) is embedded in the floor surface where the freezing and refrigeration equipment (1) is located, and when the freezing and refrigeration equipment (1) is used in a factory, it can be placed on the factory floor surface.

[0096] Also, the freezing and refrigeration equipment (1) may be embedded in the floor or placed on the floor in homes and factories.

[0097] The open upper portion of the housing (100) is covered by a step plate (190a, 190b) that a user can step on.

[0098] At this time, based on Figure 2, the freezing and refrigeration equipment (1) can be advanced or retracted in the left direction of the housing (100) by the forward and backward cylinder (150).

[0099] At this time, the stepping plate is divided into a stepping plate (190a) formed in a bellows shape and a stepping plate (190b) formed in a plate shape.

[0100] A step plate (190a) formed in a bellows shape can have one side connected to the left inner wall surface of the housing (100) via an axle (191a), and the other side connected to the left side of the additional housing (130) via an axle (191b).

[0101] The step plate (190a), formed in a bellows shape, is folded when the freezing / refrigeration equipment (1) and the additional housing (130) advance, and unfolds when the freezing / refrigeration equipment (1) and the additional housing (130) retract.

[0102] And, a step plate (190b) formed in a plate shape is fixed at one side to the right inner wall surface of the housing (100).

[0103] The stepping plates (190a) (190a, 190b) described above are formed to have a thickness capable of stably supporting the user's load.

[0104] The rotating plate (110) is attached to the bottom surface of the freezing and refrigeration equipment (1).

[0105] The rotating plate (110) can be formed of a metal material with excellent rigidity so as to stably support the load of the freezing and refrigeration equipment (1).

[0106] The rotating shaft (120) is coupled to the bottom surface of the rotating plate (110). The rotating shaft (120) is provided to rotate the rotating plate (110) and the freezing and refrigeration equipment (1). The rotating shaft (120) is equipped with a first gear (121) to receive power from a motor (140) to be described later.

[0107] The additional housing (130) can be formed by combining multiple plates into a square box shape or by manufacturing through a molding die.

[0108] The additional housing (130) is accommodated in the internal space of the housing (100) and operates forward and backward while supported by the forward and backward cylinder (150) described later.

[0109] The additional housing (130) includes a receiving space in which a rotating plate (110), a rotating shaft (120), and a motor (140) are accommodated.

[0110] At this time, the rotating plate (110) is placed on the entrance side of the additional housing (130).

[0111] And, a bearing (131) for guiding the rotation of the rotation axis (120) is embedded in the bottom surface of the additional housing (130).

[0112] Through the bearing (131), the rotating shaft (120), the rotating plate (110), and the freezing and refrigeration equipment (1) can be smoothly rotated in the forward or reverse direction.

[0113] The motor (140) is installed on the bottom surface of the additional housing (130). The motor (140) may be formed as an AC motor (140) or a DC motor (140) in which the motor shaft rotates in the forward or reverse direction.

[0114] A second gear (141) to which a first gear (121) is engaged is mounted on the motor shaft of the motor (140). At this time, the first gear (121) and the second gear (141) are spaced apart by a predetermined distance and may be connected to each other through a chain or a pulley.

[0115] Due to the connection of the first gear (121) and the second gear (141) described above, the motor shaft of the motor (140) can be rotated in the forward or reverse direction, thereby allowing the rotation shaft (120), the rotating plate (110), and the freezing and refrigeration equipment (1) to be rotated simultaneously, and thereby the angle or direction of the freezing and refrigeration equipment (1) for the user can be selectively adjusted.

[0116] The motor (140) can be controlled by a remote control (not shown) held by the user.

[0117] The remote control has a forward button for rotating the motor shaft of the motor (140) in the forward direction and a reverse button for rotating the motor shaft of the motor (140) in the reverse direction.

[0118] The forward and backward cylinder (150) is accommodated in the internal space of the housing (100). The forward and backward cylinder (150) can be formed as a rodless cylinder.

[0119] The piston of the forward and backward cylinder (150) is coupled to the bottom surface of the additional housing (130).

[0120] Through these forward and backward cylinders (150), the distance of the freezing and refrigeration equipment (1) to the user can be selectively adjusted.

[0121] The forward and backward cylinder (150) can be controlled by the aforementioned remote control (not shown).

[0122] The remote control further includes a forward button for advancing the piston of the forward and backward cylinder (150) and a backward button for retracting the piston.

[0123] These forward and backward cylinders (150) can be applied in multiple numbers to stably support the load of the freezing and refrigeration equipment (1) while moving it forward and backward.

[0124] The forward and backward cylinders (150) are arranged at a certain distance from each other, and the pistons of the forward and backward cylinders (150) are all connected to the bottom surface of the additional housing (130).

[0125] At this time, the number of forward and backward cylinders (150) can be changed according to the size of the freezing and refrigeration equipment (1).

[0126] A lifting plate (160) is attached to the bottom surface of the forward and backward cylinders (150).

[0127] The lifting plate (160) supports the forward and backward cylinders (150). Through the lifting plate (160), the lifting cylinder (180) can uniformly raise or lower the forward and backward cylinders (150).

[0128] The lifting plate (160) can be formed of a metal material with excellent rigidity so as to stably support the load of the freezing and refrigeration equipment (1).

[0129] The lifting plate (160) is raised by a support plate (170) driven by a lifting cylinder (180).

[0130] The support plates (170) are composed of a pair of two. The support plates (170) each support one side and the other side of the bottom surface of the lifting plate (160).

[0131] The lifting cylinder (180) is connected to one side and the other side of the internal space of the housing (100), respectively.

[0132] The lifting cylinder (180) is coupled to the housing (100) such that the piston faces the bottom surface of the housing (100).

[0133] The pistons of the lifting cylinder (180) are each connected to the support plate (170).

[0134] The lifting cylinder (180) can be formed as a hydraulic cylinder or a pneumatic cylinder.

[0135] When hydraulic or pneumatic pressure is supplied to the lifting cylinder (180), the piston is lowered according to FIG. 2, and the freezing and refrigeration equipment (1) is lowered. Then, when hydraulic or pneumatic pressure is discharged from the lifting cylinder (180), the piston is raised, and the freezing and refrigeration equipment (1) is raised.

[0136] Through this lifting cylinder (180), the height of the freezing and refrigeration equipment (1) for the user can be selectively adjusted.

[0137] The lifting cylinder (180) can be controlled by the aforementioned remote control (not shown).

[0138] The remote control further includes a lowering button for lowering the piston of the lifting cylinder (180) and a rising button for raising the piston.

[0139] These lifting cylinders (180) can be applied in multiple numbers to stably support the load of the freezing and refrigeration equipment (1) while lifting it.

[0140] Lifting cylinders (180) are applied in multiple numbers to one side wall and the other side wall of the housing (100), respectively. The lifting cylinders (180) are arranged at a certain distance from each other, and the pistons of all lifting cylinders (180) are connected to the support plate (170).

[0141] At this time, the number of lifting cylinders (180) can be changed according to the weight and size of the freezing and refrigeration equipment (1).

[0142] Next, an example of the use of the freezing and refrigeration equipment (1) through the motor (140) described above, the forward and backward cylinder (150), and the lifting cylinder (180) will be described.

[0143] First, a large amount of food is cooked at a sink (not shown) or workbench (not shown) located at the front (left side of FIG. 2) of the housing (100), and then the food is placed in a storage container.

[0144] In the case of large quantities of food, it is placed in a large storage container or divided into several containers.

[0145] And, in order to maintain the freshness of the food, the storage container must be stored in the refrigerator (11) or freezer (12).

[0146] In this case, when a large storage container is filled with food, it is not easy for the user to move the large container to the food because the container is heavy.

[0147] Therefore, the user can press the forward button provided on the remote control to move the forward and backward cylinder (150) to a position close to themselves.

[0148] Then, when the user is positioned close to the front of the freezing and refrigeration equipment (1), the user can open the first opening / closing door (60) or the second opening / closing door (70) and store the storage container in the refrigerator room (11) or the freezer room (12).

[0149] Afterwards, the user can press the reverse button to return the freezing and refrigeration equipment (1) to its original position.

[0150] At this time, the forward and backward cylinder (150) is programmed so that the piston moves forward only while the forward button is pressed, and the piston moves backward only while the backward button is pressed.

[0151] Meanwhile, when the user presses the forward button to move the freezing and refrigeration equipment (1) to a position close to them, if the first opening / closing door (60) and the second opening / closing door (70) do not face them, they can press the forward button or the reverse button to set the first opening / closing door (60) and the second opening / closing door (70) to face them, and then store the storage container in the refrigerator room (11) or freezer room (12).

[0152] At this time, the motor (140) is programmed so that the motor shaft rotates in the forward direction only while the forward button is pressed, and the motor shaft rotates in the reverse direction only while the reverse button is pressed.

[0153] And, the motor (140) is programmed so that it does not operate unless the forward button and the reverse button are pressed.

[0154] Therefore, the user can adjust the first opening / closing door (60) and the second opening / closing door (70) so that they face each other accurately by operating the forward button or the reverse button.

[0155] Meanwhile, when a user presses the forward button to move the freezing and refrigeration equipment (1) to a nearby position and intends to place a storage container on the tray (14) placed on the lowest level of the refrigerator room (11) or on the bottom surface (10a) of the refrigerator room (11) placed below the tray (14), the user must lower their posture, such as by bending their waist or sitting down. At this time, if the storage container is heavy, it puts strain on the waist.

[0156] Therefore, the user simply presses the rise button to retract the piston of the lifting cylinder (180) into the interior of the lifting cylinder (180). In this case, the piston raises the support plate (170), thereby raising the lifting plate (160), the forward / reverse cylinder (150), the additional housing (130), the rotating plate (110), and the freezing / refrigeration equipment (1). As a result, the height of the tray (14) and the bottom surface (10a) placed on the lowest level of the refrigerator room (11) is increased. Consequently, even with the user lowering their posture slightly, the storage container can be easily stored on the tray (14) or the bottom surface (10a) placed on the lowest level.

[0157] At this time, when raising or lowering the freezing and refrigeration equipment (1) by pressing the up button or down button, the bellows-type step plate (190a) rotates in the up and down directions with respect to the axis (191a, 191b).

[0158] Additionally, the lifting cylinder (180) is programmed so that the piston rises only while the lifting button is pressed and the piston lowers only while the lowering button is pressed.

[0159] And, the lifting cylinder (180) is programmed so that it does not operate unless the lifting button and the lowering button are pressed.

[0160] Therefore, the user can adjust the height of the freezing and refrigeration equipment (1) by operating the up button or the down button.
