[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator suitable for display at a store.

[0002]

2. Description of the Related Art When a refrigerator is displayed at a store, the power is turned off. This is because, when the power is turned on, a compressor or the like is driven to waste power.

[0003]

[Problems to be Solved by the Invention] However, when the display is turned off, there is a problem that the interior of the refrigerator cannot be seen well because the interior lamp does not light even when the door is opened.

[0004] The present invention has been made in view of the above circumstances. Therefore, the purpose of the present invention is to provide a refrigerator that can prevent waste of electric power and can fully view the inside of a refrigerator when exhibited at a store. To provide.

[0005]

SUMMARY OF THE INVENTION The refrigerator of the present invention has a first terminal for forming a cooling operation energizing circuit for energizing in a normal cooling operation mode, and does not drive a compressor or the like. A second terminal portion for forming an exhibition energizing circuit for energizing the inner lamp ;
And display energization circuit while being connected to the second terminal together with the provided interchangeable on the second terminal portion to form a conducting circuit for cooling operation connection state to the first terminal portion The feature is that a circuit forming member to be formed is provided.

[0006]

When a refrigerator is displayed at a store, the circuit forming member is changed from the first terminal portion to the second terminal portion, and the ordinary cooling operation energizing circuit is switched to the exhibition energizing circuit. Thus, even when the power is turned on, the compressor and the like are not driven, so that power is not wasted. Since the exhibition is performed with the power turned on, the interior light is turned on when the door is opened, so that the interior of the interior can be clearly seen.

[0007] When selling a refrigerator displayed at a store, the circuit forming member is replaced from the second terminal portion to the first terminal portion to form an energizing circuit for cooling operation.

Here, as shown in FIG. 4, when the interior light side connector 11 is attached to the first board side connector 15,
The power supply bus 28 and the power supply bus 30 are connected via the lead wire 14 of the interior light connector 11 and the leads 19 and 20 of the first board connector 15, and power is supplied to the compressor 31 and the fan motor 33. A cooling operation energizing circuit 36 to be connected is formed. This cooling operation energizing circuit 3
In the state where 6 is formed, a control circuit (not shown)
, The relay switches 32 and 34 are turned on / off, and the compressor 31 and the fan motor 33 are controlled to be turned off and on. That is, in the state where the cooling operation energizing circuit 36 is formed, energization in the normal cooling operation mode is performed.

On the other hand, as shown in FIG. 5, when the interior light side connector 11 is mounted on the second board side connector 16, the power bus 28 is connected to the lead wire 2 of the second board side connector 16.
6, the lead wire 13 of the interior light side connector 11, the interior light 6,
The door switch 35 is connected via the lead wire 12 of the interior light connector 11 and the lead wire 25 of the second board connector 16.
, A power supply circuit is connected to the interior lamp 6, and the power supply circuit 37 for display is not connected to the compressor 31 and the fan motor 33. When the door 5 is opened and closed and the door switch 35 is operated in the state where the exhibition conducting circuit 37 is formed,
The interior lamp 6 is controlled to be turned off and on. Then, in the state where the exhibition energizing circuit 37 is formed, energization is performed in the storefront display mode in which the compressor 31 and the fan motor 33 are not energized.

Next, the operation of the above configuration will be described. At the time of shipment, the interior light side connector 11 is mounted on the first board side connector 15, and a cooling operation energizing circuit 36 shown in FIG. 4 is formed. If the plug 27 is connected to a commercial AC power supply in this state, a normal cooling operation is performed.

When the refrigerator having the above configuration is to be displayed at a store, the interior light support member 8 is removed from the mounting board 7 and the interior light side connector 11 is connected to the second board side connector 16.
Replace with Thereby, as shown in FIG. 5, the display energizing circuit 37 is formed, and the mode is switched from the normal cooling operation mode to the storefront display mode. In this state, the plug 27
Is connected to a commercial AC power supply, the compressor 31 and the fan motor 33 are not energized and driven, thereby preventing waste of power. When the door 5 is opened, the contact (c-b) of the door switch 35 is closed, and the interior lamp 6 is energized and turned on. As a result, the inside of the refrigerator compartment 3 is illuminated by the interior lamp 6, and the interior of the refrigerator compartment 3 can be seen well. When the door 5 is closed, the contact (ca) of the door switch 35 is closed, and the interior light 6 is turned off.

A printed circuit board (not shown) provided with a control circuit is provided in a housing (not shown) formed on the upper part of the rear surface of the refrigerator body 1. On this printed wiring board, first and second board-side connectors for switching between a cooling operation energizing circuit and a display energizing circuit are provided, and the first and second board-side connectors are mounted on the printed wiring board. A configuration is conceivable in which the inner light connector is provided so as to be replaceable.

However, in this configuration, since the operation of replacing the internal light side connector on the printed wiring board is performed, there is a possibility that other electronic components on the printed wiring board may be damaged during the work. In addition, if the refrigerator is installed in the home of the sales destination while the current-carrying circuit is switched to the exhibition circuit, the refrigerator is usually arranged with the back side along the wall of the house. In order to replace the light-side connector, it is necessary to move the installed refrigerator to the front and remove the back plate that closes the housing portion of the printed wiring board, which is very troublesome.

On the other hand, according to the above embodiment, the first
And the second board side connectors 15 and 16 are provided on the mounting board 7, and the inside light side connector 11 is replaced with the inside light supporting member 8 removed from the mounting board 7, so that the replacement work is performed. Damage to other electronic components can be prevented. Further, when replacing the interior light connector 11, the door 5 is opened from the front side of the refrigerator, and the replacement work is performed with the interior light support member 8 removed. Even if the refrigerator is installed in the home of the sales destination in the state, the operation of moving the installed refrigerator can be eliminated, and the workability can be improved.

In the above embodiment, the first and second board-side connectors 15 and 16 are arranged vertically, but they may be arranged left and right. In the above-described embodiment, the socket 9 is connected to the interior light connector 11 via the lead wires 12 and 13. Instead, the interior light connector and the socket are integrated. Is also good. In the case of this configuration, the interior lamp supporting member for mounting the socket can be eliminated, and the number of components can be reduced.

Further, when the interior lamp supporting member 8 is mounted on the mounting substrate 7, the claws 8a are engaged with the engaging holes 7a.
When attaching the cover 10 to the interior lamp support member 8, the claws 10a are engaged with the engagement holes 8d.
The invention is not limited to this, and for example, a screwing configuration may be adopted.
