Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a refrigerant charging /

The present invention relates to a refrigerant charging and inspecting process system for a commercial refrigerator, and more particularly, to a refrigerant charging and inspecting process system in which a vacuum process and a refrigerant filling process are precisely performed in each refrigeration apparatus in the mixed- The present invention relates to a refrigerant charging and inspecting process system of a refrigerator for a business, which is capable of preventing a refrigerating device from being damaged by automatically shutting off supply of a current in an inspecting process.

The refrigerator is a device to keep foods and drinks fresh and it is an indispensable item for modern people's life. Such a refrigerator can be roughly divided into a commercial refrigerator and a household refrigerator. An object of the present invention is to solve the problem of efficiently charging and inspecting the refrigerant in a refrigerating apparatus and generating a refrigerant or the like in a mixed state when a commercial refrigerator is mixedly produced.

The commercial refrigerator is equipped with one or two freezing devices at the top or bottom. As is well known, the freezing device is composed of an evaporator, a condenser, a compressor, and an expansion valve.

The refrigerator may have one refrigerator depending on the capacity or the structure of the refrigerator and the refrigerating compartment, and in some cases, more than two refrigerators may be provided. In general, household refrigerators are mass-produced by large companies, so each model will have a dedicated production line. That is, since the same model is continuously produced in one production line, it is unlikely that a mistake or mistake is caused in the refrigerant injection or related work.

However, in small and medium-sized enterprises, small-sized commercial refrigerators that are produced in small quantities in accordance with orders or demand are often applied to a mixed production system in which a plurality of models are simultaneously produced in one production line. Mixed production refers to a system that produces different models simultaneously on a production line. In the case of a commercial refrigerator, a refrigerator having a refrigerator at an upper portion thereof, a refrigerator having a lower refrigerator, a refrigerator having a refrigerator, and a refrigerator having a plurality of refrigerators are produced simultaneously in one production line. Therefore, the completeness or the defect rate of the product greatly changes according to the skill or attention of the worker, and the increase of the defect rate immediately increases the production cost. Therefore, rather than rely solely on the skill or attentiveness of the operator, all processes are reduced through the system, and even if there is a mistake due to a mistake, there is a system that can catch errors so that no additional loss occurs in the next process need.

In the case of a refrigerator, after the basic assembling process is completed, the inside of the refrigeration apparatus is made to be in a vacuum state, and the refrigerant is filled in the refrigerating apparatus in a vacuum state. After the production of the refrigerator is completed, the refrigerator is inspected for proper operation. In the inspection process, the power consumption and the voltage of the refrigerator are tested. When the refrigerant is not normally injected, power is supplied to operate the refrigeration unit, which may seriously damage the refrigeration unit. Therefore, it is necessary to test whether the various electronic devices and device devices operate normally after accurately checking whether refrigerant is normally injected into the refrigerating device.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view of a refrigerant charging and inspecting apparatus for a commercial refrigerator according to the present invention; Fig.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a refrigerator,

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a rough flow of a refrigerant charging and inspecting apparatus of a business refrigerator according to the present invention.

Referring to FIG. 1, the apparatus for filling and inspecting refrigerant in a business refrigerator according to the present invention includes a vacuum apparatus 110, a refrigerant filling apparatus 130, an inspection apparatus 150, and a refrigerator May include a conveyor (not shown) and a controller 170 connected to the respective devices.

The apparatus for filling and inspecting the refrigerant of the business refrigerator according to the present invention is a device used for mixed production of various types of commercial refrigerators. Mixed production refers to the production of various types of models with different structures or configurations in one production line. For example, there are various types of commercial refrigerators such as a model in which a refrigerator is provided at an upper portion and a model in which a refrigerator is provided at a lower portion, a model in which one refrigerator is provided, and a model in which there are two or more refrigerators. The position and number of refrigeration units are determined according to the capacity and performance of the refrigerator. Here, the refrigerating device refers to a function of reducing the temperature of the refrigerator by combining an evaporator, a condenser, a compressor, a valve, and the like, and has a known structure.

The apparatus for filling and inspecting refrigerant of a business refrigerator according to the present invention is first applied to a step of performing a basic assembling process (S10) in a previous stage and then vacuuming the refrigerating device at the final stage of the process, . Generally, since the household refrigerator consumes a large amount, it is produced by a large company in a dedicated production line for each model. Commercial refrigerators, however, are mainly used in commercial facilities such as restaurants, and are produced in medium-sized enterprises because consumption is relatively small and specialized. And there is a tendency to produce a small quantity of various products by predicting the order or consumption of consumers. Therefore, in order to utilize the production line efficiently, many kinds of models are mixedly produced in one production line.

The conveyor is continuously disposed along the section including the vacuum apparatus 110, the coolant filling apparatus 130 and the inspection apparatus 150 to be described later and is assembled in the assembling step S10 The produced refrigerator is sequentially moved to the vacuum process (S30), the coolant filling process (S50), and the inspection process (S90). At this time, the conveyor is not necessarily limited to a particular type or type, and various known types or types can be used as long as the refrigerator can be sequentially moved according to each process as described above. For example, it is needless to say that the vacuum device 110 and the refrigerant charging device 130 are provided in a single layer, and when the inspection process (S90) is provided in two layers, an elevator type may be used as a part of the conveyor .

The vacuum apparatus 110 includes a vacuum pump, an identification code recognition unit, and a terminal. The vacuum apparatus 110 exhausts the air inside the freezer before injecting the refrigerant into the freezer, Which is a device for evacuating the gas. The identification code recognizing unit is a device for recognizing an identification code attached to each refrigerator. At this time, the identification code may be attached in advance to each refrigerator in the assembling step (S10), or may be attached just before entering the vacuum process (S30), if necessary. As the identification code, any one of various known identification codes such as a bar code, an RFID tag, a QR code and the like can be used, and the identification code recognition unit is a device for scanning the identification code. The identification code is stored in the control unit 170. Here, the control unit 170 refers to a device similar to or similar to a microcomputer. For example, the model number of the refrigerator, the position or the number of the refrigerator, and the like may be stored together in the controller 170, and at least the information about the refrigerator is stored in the identification code. Thus, when the identification code is read by the identification code recognition unit, the information about the presently read refrigerator is displayed on the terminal. The vacuum apparatus 110 may be provided in any one of the upper and lower portions of the conveyor, and a plurality of vacuum pumps may be continuously provided, and each vacuum pump may be connected to a freezing apparatus provided at an upper portion or a lower portion of the refrigerator. That is, each vacuum pump is provided with a connection pipe and is directly connected to the refrigerating device. Each vacuum pump has a unique identification number. For example, the first vacuum pump may have an identification number such as 1, the second may have an identification number such as 2, and in the case of 10 vacuum pumps, an identification number of 1 to 10 may be given.

The refrigerant charging device 130 is provided at any one of the upper and lower portions of the conveyor, and is provided continuously with the vacuum device 110 described above. That is, the refrigerant charging apparatus 130 is installed in a predetermined section immediately after the section of the vacuum apparatus 110 where the vacuum pump 110 is installed, and the refrigerant is immediately injected into the refrigerating apparatus having undergone the vacuum step S30 Respectively. The identification code recognition unit and the occupant terminal of the refrigerant charging apparatus 130 perform similar functions when they are the same as or similar to the identification code recognition unit and the terminal of the vacuum apparatus 110 described above. The identification code recognition unit, the terminal, and the like will be described later. The refrigerant charging device 130 is provided with a plurality of charge pumps, each of which has a unique identification number.

The vacuum pump and the charge pump are well known in the art and a detailed description thereof will be omitted. The functions of the vacuum device 110 and the refrigerant charging device 130 will be described later in detail.

2 is a flowchart schematically showing a refrigerant charging and inspecting method of a refrigerator for business use according to the present invention.

The method for filling and inspecting a refrigerant in a business refrigerator according to the present invention includes an assembling step (S10), a vacuum step (S30), a coolant filling step (S50), a finishing step (S70) and an inspecting step (S90).

The assembling step S10 is a step of assembling a basic form of the refrigerator. In the assembling step S10, a refrigerator equipped with a refrigerating device to be described later is formed and put into a vacuum step S30 or the like. Meanwhile, in a preferred embodiment of the present invention, the identification code is given to each refrigerator in the assembling process (S10), and the identification code and the information about the refrigerator are integrated and stored in the control unit. For example, a barcode having a specific identification code is attached to a certain refrigerator, and the barcode is recognized using a scanner and stored in the control unit 170. Then, the operator stores information on the refrigerator to which the bar code is attached, for example, information on the model name and the number of refrigeration apparatuses together with the bar code. After the assembling step S10 is completed, the refrigerator is loaded into the vacuum process S30 through the conveyor.

When the refrigerator enters the vacuum process S30, the identification code recognition unit included in the vacuum process S30 recognizes the identification code attached to the refrigerator. When the identification code is recognized, Information about the refrigerator is displayed. That is, the model name or the number of refrigeration apparatuses that are input before entering the vacuum process S30 are displayed. At this time, a vacuum pump capable of being coupled to the refrigerator of the refrigerator in which the identification code of the plurality of vacuum pumps is recognized is displayed together with the terminal, and the operator selects a specific vacuum pump among the plurality of vacuum pumps displayed on the terminal, Lt; / RTI > Although not shown in the drawings, the identification code recognizing unit described above may be provided with at least one or more than one in the vacuum process step S30.

As described above, the vacuum apparatus 110 provided in the vacuum process S30 is provided with a plurality of vacuum pumps. At this time, although one refrigerator may be inserted in the vacuum process (S30), a plurality of refrigerators may be inserted in some cases. In this case, some of the vacuum pumps may already be connected to the refrigerator of another refrigerator to perform a vacuum operation. In this case, the controller 170 displays the remaining usable vacuum pumps except the currently operating vacuum pump on the terminal, and the operator couples a specific vacuum pump among the available vacuum pumps displayed on the terminal to the freezing device. Then, information about the vacuum pump currently connected to the refrigerating device is displayed on the terminal. When the operator operates the vacuum pump, the information about the vacuum pump is combined with the identification code and stored, and the vacuum pump is driven.

For example, assuming that a first refrigerator having one refrigeration unit is first put into a vacuum process (S30) and a vacuum pump # 1 is coupled to perform a vacuum operation, a second refrigerator having two refrigeration units is subjected to a vacuum process S30), the identification code recognizing unit recognizes the identification code of the second refrigerator. Then, it is indicated that two refrigerating devices are provided together with information on the second refrigerator in the operator's terminal, and the vacuum pump No. 1 currently used is excluded (vacuum pumps not used due to failure etc. are also excluded) A pump (for example, 2 to 10) is displayed. At this time, when the operator connects the second and third freezing devices to the second freezing device, the operator's terminal displays the second and third times. Then, when the operator operates the vacuum pump, the vacuum pumps # 2 and # 3 vacuum the refrigerating device while simultaneously storing the identification code and the vacuum operation performed by the vacuum pumps # 2 and # 3. If the third refrigerator is inserted into the vacuum process (S30) and the identification code recognizing unit recognizes the identification code of the third refrigerator, information on the number of refrigeration units of the refrigerator to which the third identification code is attached At the same time, the available vacuum pumps except for the first, second and third vacuum pumps currently being used are displayed on the terminal, and the operator can work by connecting a specific vacuum pump to the freezing device among the available vacuum pumps .

The refrigerant filling step (S50) is performed by charging the refrigerant through the vacuum step (S30), and is continuously connected to the vacuum step (S30) as described above. In the refrigerant charging step (S50), a plurality of refrigerant charge pumps (not shown) are provided. Thus, the refrigerator that has undergone the vacuum process (S30) is immediately introduced into the refrigerant charging process (S50) along the conveyor.

When the refrigerator having passed through the vacuum process (S30) is charged in the refrigerant charging process (S50), the identification code recognizing unit provided in the refrigerant charging process (S50) recognizes the identification code of the refrigerator again. Then, the information on the refrigeration apparatus of the refrigerator to which the identification code is attached is displayed on the operator's terminal, and at the same time, the information about the operation details in the vacuum process (S30) is displayed together with the terminal. At this time, in case that only one vacuum pump is connected to the refrigerator despite the fact that two refrigerating devices are provided in the currently read identification number, the operator passes the refrigerant without performing any further refrigerant filling step (S50). At this time, if necessary, mark the corresponding refrigerator (S30) to indicate that the vacuum process (S30) is wrong so that the refrigerator is removed from the conveyor in the required process or no further work is performed in the subsequent process.

Because the refrigerator is large and very heavy and the work process is continuous along the conveyor, it is often difficult to stop the entire line of operation or to remove the wrong refrigerator in the middle of the work process, even if there is a wrong refrigerator in the middle. Especially when a large number of mechanical equipments such as the refrigerant charging device 130 are installed around the conveyor. Therefore, it is desirable to pass the refrigerator without doing any additional work, and to filter out the mistaken refrigerator at an appropriate stage or position so as to perform the operation again.

On the other hand, when the refrigerating device recognized by the identification code recognizing part provided in the refrigerant filling step (S50) performs a normal operation in the vacuum step (S30), the operator uses the refrigerant charge pump to cool the refrigerating device Charging. At least one or more identification code recognizing units may be provided in the refrigerant charging process (S50).

The coolant filling step (S50) is similar to the vacuum step (S30). First, the operator's terminal displays a charge pump that can be coupled to the refrigeration unit, along with information about the refrigeration unit, and the operator couples a particular charge pump to the refrigeration unit among the plurality of displayed charge pumps. At this time, when the operator attaches the specific charge pump to the freezing device, the combined charge pump is displayed on the terminal, and when the operator operates the charge pump, the information on the charge pump for progressing the charge is stored together with the identification code.

When the refrigerant filling step (S50) is completed, a finishing step (S70) is provided. The finishing step (S70) is a step of finishing the refrigerator before the inspection step (S90). For example, for the vacuum process (S30) and the refrigerant filling process (S50), the refrigerating apparatus of the refrigerator may be subjected to a work process in a state exposed to the outside. In this case, it may be possible to attach the cover of the refrigeration apparatus in the finishing process (S70) or to remove the mistaken refrigerator from the working process. If the finishing step S70 is not necessary, the finishing step S70 may be omitted. After the finishing process (S70), an inspection process (S90) for testing the performance of the refrigerator is followed.

The inspection step (S90) is a step of testing the various performances of the refrigerator after the completion of the assembly and the vacuum step (S30) and the refrigerant filling step (S50). For example, the refrigerator's refrigeration unit can be tested for normal operation and whether the power consumption and voltage meet the design values. The inspection items performed in the inspection process (S90) may include all the items that are normally used in the refrigerator production process, and these inspection items are omitted from the public notice.

At this time, in order to inspect the refrigerator, a current must be supplied to the refrigerator. However, if the refrigerant is not normally charged, current may be supplied to the refrigerating device to severely damage the refrigerating device. Therefore, in the inspection process (S90), the operation data stored in the vacuum process (S30) and the coolant charge process (S50) are used in advance to prevent such an accident.

First, when the refrigerator is inserted into the inspecting step (S90), the identification code recognizing unit provided in the inspecting step (S90) recognizes the identification code attached to the refrigerator. When the inspecting device 150 recognizes the identification code of the refrigerator, information on the refrigeration apparatus of the refrigerator to which the identification code is attached and the information about the vacuum process S30, the vacuum pump stored in the refrigerant filling process S50, Are all displayed. Then, the operator can view the terminal and check whether the vacuum process (S30) is normally performed and whether the refrigerant is normally charged. Thus, the operator can stop the inspecting step (S90) without energizing the current in the case of a refrigerator having an abnormality in the freezing apparatus.

On the other hand, when the operator can not confirm the terminal by mistake or presses the wrong report button, the control unit 170 automatically detects the current (current) when there is an abnormality in either the vacuum process S30 or the refrigerant filling process S50 Thereby preventing the refrigerating device from being damaged.

Meanwhile, in a preferred embodiment of the present invention, in the above-described vacuum process (S30), the coolant filling process (S50), and the inspection process (S90), the operator information on the worker may be combined and combined with the identification code. Thus, it is possible to check at a glance the defect rate for each worker, the defect rate occurring in each vacuum pump or the charge pump, and the like. For example, if a particular operator has a high percentage of defects in a particular process, the worker may be excluded from the process and placed in another process, and if a particular vacuum pump or charge pump experiences repeated problems, The pump can be serviced or replaced. Here, the worker information can be a name or an employee number to identify the worker who has performed the work.

3, the vacuum process and the filling process according to the present invention are performed in the vacuum / filling process F10 provided at the bottom of the drawing, and the finishing process F30 is continued to the next step of the vacuum filling process F10. The portions denoted by the assembling process and the foaming process except for the vacuum / filling process (F10) and the finishing process (F30) correspond to the pre-stage assembling process of the present invention. Therefore, the refrigerant charging method of the present invention is applied to assemble the basic form of the refrigerator after various components are formed in the frame of the refrigerator in the assembling process and then fill the refrigerant in the final stage. The foaming process refers to a process of filling a heat insulating material such as a door and a wall of a refrigerator where heat insulation is required. The basic assembly process and the foaming process of the refrigerator are well known in the art and will not be described in detail.

Meanwhile, in the refrigerant charging and inspecting method of the refrigerator for business use according to the present invention, the inspecting step (F50) may be continued to the next stage of the vacuum / filling step (F10) and the finishing step (F30). However, in the case where the internal space of the factory is narrow, some processes may be provided in different layers as shown in the figure. At this time, the refrigerator can be moved by vertical movement means such as an elevator.

FIG. 4 shows a form in which the inspecting step (F50) is provided in a separate layer. As shown in the drawings, the method of filling and inspecting the refrigerant of the business refrigerator according to the present invention may include some processes in different layers or may be provided in the same layer as necessary.
