[0003] Patent Document 1 Japanese Unexamined Patent Publication No. 2013-61121 Summary of Invention Problem to be Solved by the Invention
[0004] The present disclosure addresses the problem that when an operation board is installed inside the refrigerator compartment, it is necessary to open the refrigerator compartment door to check the setting state, which causes cold air to escape and reduces refrigeration efficiency. The present disclosure provides a refrigerator that allows a user to perform required operations without confusion by providing an operation board on the surface of the outer door of the refrigerator compartment to display only the minimum necessary information. Means for Solving the Problem
[0005] A refrigerator according to the present disclosure includes: a housing having a storage compartment therein; a door supported by the housing to be openable and closable to close the storage compartment; a setting unit for operating settings of the refrigerator; and a control unit for executing control set by the setting unit, wherein the setting unit is provided on the door, a light source is provided in the setting unit, and the control unit determines lighting settings of the light source based on an operation mode set by the setting unit. Effects of the Invention
[0006] The refrigerator in this disclosure is equipped with an operating circuit board on the surface of the refrigerator door and displays only minimal information, thereby enabling the user to perform the necessary operations without confusion. [Brief explanation of the drawing]
[0007] [Figure 1] Front view of the refrigerator in Embodiment 1 [Figure 2] Front view of the refrigerator with the refrigerator door open in Embodiment 1 [Figure 3] Front view of the refrigerator control board in Embodiment 1 [Figure 4] Block diagram showing the block configuration of the refrigerator in Embodiment 1 [Figure 5] Flowchart showing the overall operation in Embodiment 1 [Figure 6] Flowchart showing the operation of the main board in Embodiment 1 [Figure 7] Flowchart showing the operation of the control board in Embodiment 1 [Modes for carrying out the invention]
[0008] (Knowledge and other information that formed the basis of this disclosure) At the time the inventors conceived this disclosure, the control board was located inside the refrigerator compartment, requiring the door to be opened to set functions, which reduced cooling efficiency. Furthermore, a dedicated notification mechanism had to be installed outside the refrigerator compartment to notify the function setting status. In order to avoid these issues, the control board was sometimes installed on the surface of the door outside the refrigerator compartment.
[0009] However, the inventors discovered that when the control board is installed on the surface of the door outside the refrigerator compartment, the aesthetic design is poor. To solve this problem, they arrived at the subject matter of this disclosure.
[0010] Therefore, this disclosure provides a refrigerator equipped with a notification function on the control board inside the refrigerator compartment.
[0011] The embodiments will be described in detail below with reference to the drawings. However, unnecessary details may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted. This is to avoid the following explanation becoming unnecessarily verbose and to facilitate understanding for those skilled in the art.
[0012] The attached drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims.
[0013] (Embodiment 1) Embodiment 1 will be described below with reference to Figures 1 to 4.

[0034] The output unit 225 is connected to the output circuit 226 provided on the second board 202 and receives signals from an output load 227, which may include a buzzer or LED that indicates a specific refrigerator state.
[0035] [1-2. Operation] [1-2-1. Overall Operation] Figure 5 is a flowchart showing the operation of the refrigerator 100. Based on Figure 5, the operation from the state in which power is supplied to the refrigerator 100 (second circuit board 202) to the determination and execution of a special operating mode will be explained.
[0036] First, the second board 202 is determined to determine whether the special operation mode setting is ON or OFF (step S301). If the second board 202 determines that the special operation mode setting is ON (step S301: Yes), the LED is set to light up (step S302). The second board 202 receives the first identifier and starts the refrigerator door open determination process for the first identifier (step S304). If the second board 202 determines that the special operation mode setting is not ON (step S301: No), the LED is set to turn off (step S303).
[0037] Next, if the second circuit board 202 determines that the first identifier is open (step S304: Yes), the LED lights up dimly (step S305). If the second circuit board 202 determines that the first identifier is not open (step S304: No), the LED lights up brightly (step S306).
[0038] [1-2-2. First Identifier Update Process] Figure 6 is a flowchart showing the update process for the first identifier. Based on Figure 6, the operation from the state in which the first board 201 is powered up to the update of the first identifier will be explained.
[0039] First, when power is supplied to the first board 201, the first board 201 processes the input of the refrigerator door switch from the input load 214 via the input circuit 213 and input unit 212 (step S401). The first board 201 then performs a first identifier update process using the update means 207 (step S402). After that, it transmits the first identifier to the second board 202 via the communication unit 209 (step S403).
[0040] [1-2-3. Special Operation Mode Settings] Figure 7 is a flowchart showing the special operation mode setting process. Based on Figure 7, the process after receiving data from the first board 201 will be explained.
[0041] First, the second board 202 receives the special operation mode setting received from the first board 201 (step S501). Next, the second board 202 processes the special operation mode setting input from the input load 224 via the input circuit 223 and input section 222 (step S502). After that, it determines the special operation mode setting value (step S503).
[0042] [1-3. Effects, etc.] As described above, in this embodiment, the refrigerator 100 comprises a first circuit board 201 and a second circuit board 202. The first circuit board 201 has a first identifier indicating the open / closed state of the refrigerator compartment door of the refrigerator 100, and the second circuit board 202 has a setting value for a special operation mode. The second circuit board 202 includes a receiving means 220 for receiving the first identifier from the first circuit board 201, an updating means 217 for updating the setting value for the special operation mode based on the input unit 222, and the first identifier and the setting value for the special operation mode. The system includes a determination means 218 that determines the output setting in the output unit 225, an output unit 225 that outputs the output setting, an output circuit 226, and an output load 227.
[0043] This allows the user to activate a special operating mode from the control board inside the refrigerator compartment without having to open or close the door. Therefore, there is no need to include a separate notification mechanism in the refrigerator's internal structure.
[0044] As in this embodiment, the configuration may also involve updating the first identifier from the input section 212 of the first substrate 201.
[0045] This allows the RGB LED module on the control board to be dimmed when the refrigerator door is opened. Therefore, it suppresses glare from strong light sources, enabling users to comfortably obtain visual information for extended periods.
[0046] Furthermore, in this embodiment, the control board 108 may be equipped with an RGB LED module 109 for notifying special operating modes.
[0047] As a result, the RGB LED module on the control board is installed on the side of the refrigerator door, and because the refrigerator door is made of metal parts, the light from the light source can be reflected more effectively. Therefore, it becomes possible for the user to easily recognize notifications regarding the status of the refrigerator.
[0048] In this embodiment, the refrigerator 100 may also be provided with a second substrate 202 on the side surface of the refrigerator compartment door 102.
[0049] This allows the light to illuminate when the refrigerator door is closed, provided a special operating mode is set. Therefore, it effectively makes it easier for users to recognize the information about the special operating mode.
[0050] Furthermore, in this embodiment, the second board 202 may be provided with means for setting a special operating mode from the input section 222. [Industrial applicability]
[0051] This disclosure allows the status of the refrigerator to be notified via an operating board located inside the refrigerator compartment, regardless of whether the door is open or closed. [Explanation of Symbols]
