  FIG. 4 shows a preferred structure example of the light source 40 shown in FIGS.

  FIG. 4A is a front view of the light source 40, and FIG. 4B is a cross-sectional view of the light source 40. As shown in FIG. 4, the light source 40 includes, for example, a substrate 40A and light emitting elements 41, 42, and 43 arranged at intervals on the substrate 40A. The light emitting elements 41, 42, 43 preferably use LED (light emitting diode) elements. For example, the light emitting elements 41, 43 generate white light, and the light emitting element 42 generates blue light.

  However, the structure of the light source 40 shown in FIG. 4 is an example, and the number of light-emitting elements and the emission color can be arbitrarily selected. For example, in another example of the light source 40, as shown in FIG. 4C, the light emitting elements 41A, 42A, and 43A preferably use LED (light emitting diode) elements. For example, the light emitting element 41A has red light ( R) may be generated, the light emitting element 42A may generate green light (G), and the light emitting element 43A may generate blue light (B).

  Thus, since the light emitting elements 41, 42, 43 (41A, 42A, 43A) of the light source 40 have different color tones (light emission colors), the user can use the light emitting elements 41, 42 of the light source 40. , 43 (41A, 42A, 43A) by changing the color tone emitted by the light source 40 according to the presence or absence of light emission, the user can easily see the change in the environment that occurs in the storage chamber 20 shown in FIGS.

Moreover, it can also carry out with a predetermined | prescribed pattern by setting the order of light emission of the light emitting elements 41, 42, 43 (41A, 42A, 43A) of the light source 40.

  FIG. 5 is a horizontal sectional view taken along line NN of the refrigerator 1 shown in FIG.

  As shown in FIG. 5, the left door 7 and the right door 8 are in an open state. A light source 60 is disposed inside the left door 7, and another light source 61 is disposed inside the right door 8. Although these light sources 60 and 61 use LED as a light emitting element, they are not specifically limited. As the light sources 60 and 61, for example, the same structure as the light source 40 as shown in FIG. 4 can be adopted.

  As illustrated in FIG. 5, when the left door 7 and the right door 8 are opened, the light source 60 generates the illumination light L1 and the light source 61 generates the illumination light L2. Both of these illumination lights L1 and L2 irradiate the storage chamber 20 in the main body 1A.

  In the state where the refrigerator 1 is placed at the storefront for display, the refrigerator 1 can be operated in the storefront display mode for the customer for sales promotion. In the store display operation in the store display mode of the refrigerator 1, when the left and right doors 7 and 8 are opened, the illumination lights L1 and L2 generated by the light sources 60 and 61 are stored in the storage room 20 as shown in FIG. Illuminate. At this time, the color tone or lighting pattern of the light sources 60 and 61 is switched.

  FIG. 6 is a block diagram illustrating a connection example of the control unit 100 of the refrigerator 1 illustrated in FIG. 1 and electrical components connected to the control unit 100.

  The control unit 100 shown in FIG. 6 is preferably arranged in the main body 1A shown in FIG. The control unit 100 includes a refrigerated cold air circulation fan 31 (hereinafter referred to as a fan 31), a light source 40, a light source 60 for illumination of the left door 7, a light source 61 for illumination of the right door 8, and bacteria or smell. , The barometric pressure sensing device 30, the color tone designation unit 70, the color tone switching presence / absence designation unit 80, and a vacuum pump 77 as a decompression device. The storage unit 20 can be illuminated by turning on the light source 40, the light source 60 for illuminating the left door 7, and the light source 61 for illuminating the right door 8.

  In the case of the storefront display mode that operates in a state where the refrigerator 1 is placed at the storefront, for example, when the deodorizing and sterilizing component generating means 50 that is the internal environment changing means exhibits the functions of deodorization and sterilization, When the vacuum pump 77 as a pressure reducing device which is an environment changing means depressurizes the inside of the storage chamber 20 shown in FIG. 2 and the atmospheric pressure in the storage chamber 20 is lower than the atmospheric pressure, the environment in the storage chamber 20 is changed. This is when the movement is changing. In the storefront display mode that operates in a state where the refrigerator 1 is placed in such a storefront, the control unit 100 is simulated, and the light emitting elements 41, 42, and 43 of the light source 40 are in accordance with instructions from the control unit 100. The light color tone or lighting pattern can be switched by simulation.

  Further, when the vacuum pump 77 depressurizes the inside of the storage chamber 20 shown in FIG. 2, the lid of the drawer container of the vegetable chamber 3 is preferably provided with a lid open / close sensor, and the lid opens and closes. When is turned on, the light emitting elements 41, 42, and 43 of the light source 40 may switch the color tone of the light or the lighting pattern according to a command from the control unit 100. When the lid is closed, the lid open / close sensor is turned off, and the light emitting elements 41, 42, and 43 return to their original states.

  Alternatively, as another example, when the user uses the refrigerator 1 in the kitchen, instead of the storefront display mode that operates in a state where the refrigerator 1 is placed at the store, the deodorizing and sterilizing component generating means 50 is deodorized. When the function of sterilization is exhibited, or when the vacuum pump 77, which is a decompression device, depressurizes the storage chamber 20 shown in FIG. 2, and the atmospheric pressure in the storage chamber 20 falls below the atmospheric pressure, FIG. The light emitting elements 41, 42, and 43 of the light source 40 shown in FIG. 4 can switch the light color tone or lighting pattern according to a command from the control unit 100. That is, the control unit 100 changes the color tone of light by selectively lighting one or more of the light emitting elements 41, 42, 43, or the timing of lighting one or more of the light emitting elements 41, 42, 43. By changing, it can be lit in a predetermined pattern.

  Further, the light source 40 shown in FIG. 6, the light source 60 for lighting the left door 7, and the light source 61 for lighting the right door 8 have the refrigerator 1 displayed at the store in accordance with instructions from the control unit 100. In the state, the refrigerator 1 can be operated in the storefront display mode for the customer for sales promotion.

  In the store display operation in the store display mode of the refrigerator 1, the control unit 100 changes the color tone of the light by selectively lighting one or more of the LEDs 40, 41, 42 of the light source 40, or The lighting pattern of the LEDs 40, 41, 42 can be changed. Further, by changing the timing of turning on the light sources 60 and 61, it is possible to light up with a predetermined lighting pattern. As the types of the light sources 60 and 61 of the left and right doors 7 and 8, LEDs or other structures can be used as light emitting elements.

  As described above, the bacterium or odor sensing device 25 shown in FIG. 6 senses the bacterium or odor in the storage room 20, and when the bacterium or odor in the storage room 20 is equal to or lower than a predetermined reference value. The sensing device 25 sends a sensing signal R to the control unit 100. Thereby, the control part 100 can switch the color tone of the light source 40, or a lighting pattern.

  Moreover, the vacuum pump 77 as a decompression device shown in FIG. 6 can make the inside of the refrigerator compartment 2 and the storage chamber 20 into a decompression environment by the instruction | indication of the control part 100. FIG. As described above, when the pressure sensing device 30 senses that the pressure in the storage chamber 20 is reduced by the decompression device and the pressure in the refrigerator compartment 2 and the storage chamber 20 is reduced from the atmospheric pressure, the pressure sensing device 30. Sends a sensing signal G to the controller 100. Thereby, the control part 100 can switch the color tone of the light source 40, or a lighting pattern.

  In order to appeal the function to the customer in a state where the refrigerator 1 is displayed at the store, the control unit 100 shown in FIG. 6 can operate the light source 40 and the light sources 60 and 61 in the store display mode. .

  In the storefront display mode, the color tone designating unit 70 can arbitrarily designate the color tone of the light source 40 to the control unit 100 by being pressed and designated by the user (storefront display person in charge). Accordingly, the user can improve the recognition effect by setting the color tone of the light source 40 to a color tone that is easy for the customer and the user (store display person in charge) to recognize.

  Further, in the storefront display mode, the user presses the color tone switching presence / absence specifying unit 80 to specify whether or not the color tone of the light source 40 needs to be switched, thereby switching the color tone of the light source 40 to the control unit 100. It is possible to specify whether or not there is a necessity. Thereby, when the customer or the user (store display person in charge) feels that the color tone switching of the light source 40 is troublesome, the color tone switching presence / absence specifying unit 80 switches the color tone of the light source 40 to the control unit 100. The operation can be stopped (prohibited).

  Next, an operation example of the refrigerator 1 described above will be described.

<Example of operation in store display mode when refrigerator 1 is displayed at store>
FIG. 7 shows the display of the refrigerator 1 when the user (store display person in charge) appeals the characteristics of the refrigerator 1 to the customer for sales promotion in a state where the refrigerator 1 is placed at the store. It is a flowchart which shows the example operated by a mode.

  In the storefront display mode example described with reference to the flowchart shown in FIG. 7, for example, the control unit 100 of the refrigerator 1 placed at the storefront is, for example, an internal environment changing unit that changes the environment in the storage room 20. The demonstration of “rapid chilling” can be performed by rotating and stopping the fan 31 of the storage room 20. The demonstration of “rapid chilling” is an example of an operation that changes the environment in the storage room 20, so the control unit 100 switches the color tone or lighting pattern of the light source 40 by simulation. be able to.

  Steps S1 to S4 shown in FIG. 7 show a demonstration effect example of “rapid chilling” in the storage room 20. This “rapid chilled” is also called a quick chilled chilled chilling mode. It is a mode in which minus cold air that does not freeze the food is powerfully sent and cooled, and the food is quickly cooled while being protected from freezing and drying, thereby maintaining the freshness.

  As in steps S1 to S4 shown in FIG. 7, the operation of rotating the fan 31 at the maximum and the operation of stopping the rotation of the fan 31 when rapidly chilling the storage chamber 20 change the environment in the storage chamber 20. It corresponds to the internal environment changing means.

  In step S1 in the demonstration example of “rapid chilled”, as shown in FIG. 2, when the customer opens at least one of the left door 7 and the right door 8 of the refrigerator 1 displayed in the store, FIG. The control unit 100 shown rotates the fan 31 at maximum for a predetermined time for the storage room 20 and the refrigerator compartment 2. The range of the predetermined time for rotating the fan 31 at the maximum is, for example, 3 to 11 seconds, for example, 11 seconds. At this time, the light emitting elements 41 and 43 of the light source 40 in FIG. 6 emit white light and are lit white, but the light emitting element 42 emits blue light and blinks blue light. For example, the blue light emitting element 42 repeats an operation of turning on for 1 second and then turning off for 1 second.

  Next, in step S2 following step S1, the control unit 100 shown in FIG. 6 stops the rotation of the fan 31. The range of the predetermined time for stopping the fan 31 is, for example, 2 seconds to 5 seconds, for example, 5 seconds. At this time, the light emitting elements 41 and 43 of the light source 40 of FIG. 6 emit white light and light up with white illumination, and the light emitting element 42 emits blue light and lights up with blue light.

  Next, in step S3, the control unit 100 shown in FIG. 6 again rotates the fan 31 for a predetermined time again for the storage chamber 20 and the refrigerator compartment 2. The range of the predetermined time for rotating the fan 31 at the maximum is, for example, 3 to 11 seconds, for example, 11 seconds. At this time, the light emitting elements 41 and 43 of the light source 40 in FIG. 6 emit white light and are lit white, but the light emitting element 42 emits blue light and blinks blue light. For example, the blue light emitting element 42 repeats an operation of turning on for 1 second and then turning off for 1 second.

  Next, in step S4, the control unit 100 shown in FIG. 6 stops the rotation of the fan 31 again. The range of the predetermined time for stopping the fan 31 is, for example, 2 seconds to 5 seconds, for example, 5 seconds. At this time, the light emitting elements 41 and 43 of the light source 40 of FIG. 6 emit white light and light up with white illumination, and the light emitting element 42 emits blue light and lights up with blue light.

  Next, step S5 to step S8 shown in FIG. 7 show a demonstration effect example of front bright illumination for the storage unit 20 by the light sources 60 and 61 of the doors 7 and 8. As shown in FIG. 5, with the left and right doors 7 and 8 open, the control unit 100 shown in FIG. 6 blinks the illumination lights L1 and L2 of the light sources 60 and 61 that are door lights in a predetermined pattern. . Thereby, the storage room 20 can be front bright illuminated from the front side, and the effect of the demonstration effect for the customer who came to see the refrigerator 1 can be further improved.

  In step S5 of FIG. 7, the control unit 100 shown in FIG. 6 turns off the light sources 60 and 61 for 2 seconds, for example, and turns on the light sources 60 and 61 for 5 seconds in step S6. In step S7, the control unit 100 turns off the light sources 60 and 61 again for 2 seconds, for example, and turns on the light sources 60 and 61 again for 5 seconds in step S8.

  As described above, by using the illumination lights L1 and L2 generated by the light sources 60 and 61 that are the door illuminations shown in FIG. 5, the storage chamber 20 blinks in a predetermined pattern from the front side. When the demonstration effect of performing the front bright illumination is finished and the customer closes the left and right doors 7 and 8, the control unit 100 turns off the light source 40 and the light sources 60 and 61.

  In addition, if the customer closes the left and right doors 7 and 8 during the demonstration performance while performing the demonstration performance from step S1 to step S8, the control unit 100 stops the demonstration performance. The light sources 40, 60, 61 are turned off.

  Even if the customer first opens at least one of the left and right doors 7 and 8, the control unit 100 always starts the demonstration effect from the first step S1. Further, after the customer closes the left and right doors 7 and 8 in the middle of the demonstration production, if the customer opens at least one of the left and right doors 7 and 8 again, the control unit 100 always performs the demonstration production. The process always starts from the first step S1.

  When the demonstration effects from step S1 to step S8 are completed, the refrigerator 1 moves to a normal operation.

  Incidentally, the light source 40 shown in FIG. 6 includes light emitting elements 41 and 43 that emit a plurality of color tones and white light, and a light emitting element 42 that emits blue light. Using the color tone designation unit 70, the color tone of the light source 40 can be designated for the control unit 100. Thereby, the effect of the demonstration effect can be obtained by selecting the color tone of the light source to a color that is easily recognized by the customer or user (store display person in charge).

  Further, whether or not it is necessary to switch the color tone of the light source can be specified to the control unit 100 by the user (store display person in charge) using the color tone switching presence / absence specifying unit 80 shown in FIG. Thereby, a customer or a user (store display person in charge) who feels that the color tone switching operation of the light emitting elements 41, 42, and 43 of the light source 40 is troublesome to the control unit 100 so that the color switching operation does not occur. The color switching operation can be stopped.

  In the storefront display mode that operates in a state where the refrigerator is placed at the storefront, the control unit 100 switches the color tone or lighting pattern of the light source 40 and the lighting pattern of the light sources 60 and 61. As a result, when the customer opens one of the left and right doors 7 and 8, the customer knows that the demonstration is being performed in the storefront display mode, and the lighting color or lighting pattern of the light source 40 is switched. When the lighting patterns of the light sources 60 and 61 are switched, there is an advantage that the customer's attention can be drawn to the storage room 20 that is the switched irradiation location.

  Further, for example, in the storefront display mode that operates in a state where the refrigerator 1 of FIG. 1 is placed at the storefront, the deodorizing / sterilizing component generating means 50 that is the internal environment changing means exhibits the functions of deodorizing and sterilizing. In addition, when the vacuum pump 77 as a decompression device, which is an internal environment changing means, depressurizes the inside of the storage chamber 20 shown in FIG. 2 and the atmospheric pressure in the storage chamber 20 falls below the atmospheric pressure, the storage chamber 20 It is when it is operating to change the environment inside. Therefore, in the storefront display mode that operates in a state where the refrigerator 1 is placed, the control unit 100 simulates the light emitting elements 41, 42, and 43 of the light source 40 according to instructions from the control unit 100. Or, the lighting pattern can be switched.

<Operation example when the user actually uses the refrigerator 1>
Next, the case where the user actually uses the refrigerator 1 will be briefly described although it is not the storefront display mode in which the refrigerator 1 is placed at the storefront.

  When the refrigerator 1 is actually used, if the deodorizing and sanitizing component generating means 50, which is the internal environment changing means shown in FIG. 3, performs the function of deodorizing and sanitizing, the bacteria and odor components in the air are Powerfully disassemble and remove. The bacteria or odor sensing device 25 in the storage room 20 sends a sensing signal R to the control unit 100 shown in FIG. 6 when the bacteria or odor in the storage room 20 is equal to or lower than a predetermined reference value. 100 switches the color tone or lighting pattern of the light source 40. Thereby, the user can recognize visually and easily the operation and effect of the sterilization and deodorization of the deodorization and sterilization component generating means 50 by switching the color tone or lighting pattern of the light source 40.

  The color tone switching of the light source 40 is, for example, changing white light emission of the light emitting elements 41 and 43 to blue light emission of the light emitting element 42 or changing blue light emission of the light emitting element 42 to white light emission of the light emitting elements 41 and 43. That is. The switching of the lighting pattern of the light source 40 is, for example, changing the lighting order of the light emitting elements 41, 42, 43 or changing the number of lights.

  Thereby, the deodorizing and sanitizing component generating means 50 exhibits antibacterial and deodorizing functions in the storage room 20 by suppressing the growth of bacteria and the transfer of odors in the storage room 20 to clean the inside of the storage room. Can keep.

  When the user opens at least one of the left door 7 and the right door 8, the light source 40 preferably emits blue light in the light source 40 so that the antibacterial / deodorizing function is turned on. Most preferably, it occurs and the user can recognize the antibacterial deodorizing function by viewing the blue light.

  A case where the vacuum pump 77 shown in FIG. 6 operates and the atmospheric pressure sensing device 30 is depressurized from the atmospheric pressure in the storage chamber 20 will be described. When the pressure in the storage chamber 20 is reduced from the atmospheric pressure, the vacuum pump 77 that is a pressure reducing device operates to change the environment in the storage chamber 20. In this case, the atmospheric pressure sensing device 30 in FIG. 6 sends the sensing signal G to the control unit 100, so that the control unit 100 selects one or more of the light emitting elements 41, 42, 43 of the light source 40. The color tone or lighting pattern of the light source 40 is switched.

  Thereby, when the user opens at least one of the left door 7 and the right door 8, whether or not the interior of the storage chamber 20 is depressurized from the atmospheric pressure is determined by the color tone of the light source 40 or the lighting pattern. Can be visually recognized by switching. In order to turn on and display the decompression operation, for example, in the light source 40, for example, the light emitting elements 41 and 43 that preferably generate white light generate white light, so that the user can easily recognize the decompression function visually. be able to.

  As shown in FIG. 6, the light source 40 includes a plurality of light emitting elements 41, 42, and 43, but the plurality of light emitting elements 41, 42, and 43 change the environment in the storage chamber 20 by the control unit 100. Depending on the operation, it can also be lit in different patterns. That is, the deodorizing and sterilizing component generating means 50 exhibits an antibacterial / deodorizing function that is an operation for changing the environment in the storage chamber 20 and a vacuum pump 77 that is an operation for changing the environment in the storage chamber 20. In the case of decompression in the storage chamber 20, the light emitting elements 41, 42, and 43 can be lit in different patterns. For example, the procedure for lighting the light emitting elements 41, 42, and 43 in different patterns includes lighting the light emitting elements 41, 42, and 43 in a predetermined order and repeating the operation of lighting in this order. Thereby, the user can recognize the kind of change of the environment in the storage room 20 visually by the difference in the lighting pattern of the light emitting elements 41, 42, and 43 of the light source 40.

  When the fan 31 for sending cool air shown in FIG. 3 is set to the “rapid chilled” mode in the storage chamber 20, the control unit 100 causes the fan 31 to rotate at a higher speed than usual so that To do.

  When pulling out the chilled container 20R shown in FIG. 3, when an open / close switch (not shown) is turned on, the control unit 100 shown in FIG. 6 causes the blue light emitting element 42 of the light source 40 to blink in blue, thereby prompting the user. It is possible to produce for it.

  As described above, the refrigerator 1 according to the embodiment of the present invention operates in a state in which the main body 1A having the storage room 20, the light source 40 that is disposed in the storage room 20 and radiates light, and the refrigerator 1 is placed in the store. In the store display mode, for example, the environment in the storage room 20 is changed by rotating and stopping the fan 31 of the storage room 20, for example, as an internal environment changing means for changing the environment in the storage room 20. A control unit 100 is provided that switches the color tone or lighting pattern of the light source 40 in a simulated manner during the changing operation.

  Thereby, in the storefront display mode which operates in a state where the refrigerator 1 is placed at the storefront, the user switches the color tone of the light source 40 or the lighting pattern, for example, to change the environment in the storage room 20. For example, since the rotation and stop operation of the fan 31 of the storage chamber 20 can be specified in a simulated manner as the internal environment changing means to be changed, the customer can easily understand the operation of the internal environment change and make sure visually. Can be recognized.

  For this reason, when the refrigerator 1 is displayed over the counter and the features of the refrigerator 1 are appealed to customers, the operation of changing the internal environment of the refrigerator is simulated by switching the light color of the light source 40 or the lighting pattern, It can be clearly recognized visually and clearly for the customer.

  In the storefront mode, a function such as “rapid chilling” or the like of the refrigerator 1 is not actually driven, and the customer can be displayed and notified in a simulated manner only by light emission of the light source 40. In addition, if necessary, a customer (user) who purchased the refrigerator 1 may have various functions in the refrigerator 1, but may want to know whether the function is actually operating. Therefore, when the door is opened, the light source 40 emits light such as “quick chilling”, for example, to convince the customer and to alert the customer that it should not be opened because it is in operation. You can also do things.

  By the way, in the demonstration production, for example, when displaying in a store, when the specific operation command is notified to the control unit 100 in FIG. To set the demonstration mode. When the opening of the door is detected by the door open / close sensor when the demonstration mode is turned on, the operation of the compressor 23 in FIG. In addition to preventing the refrigerant from rotating, only the operation of the fan, which is a specific function, is turned on, and the light source 40 is added and turned on to enter a demonstration mode. It saves energy by turning off the operation.

Further, the rotation speed of the fan 31 in FIG. 6 in the demonstration mode is the same as the rotation speed of the fan in the normal “rapid chilled” mode or exceeds the rotation speed of the fan in the normal “rapid chilled” mode. It is.
In the case of the decompression mode in which the vacuum pump 77 decompresses the interior of the storage chamber 20 shown in FIG. 2, in the normal decompression mode, when the vacuum pump is on, the light source is off, the compressor is on, and the fan is on. However, when the demonstration mode is on, the vacuum pump is turned on and only a specific function is turned on, and the light source is turned on to improve visibility, and the fans and compressors that are not a specific function are turned off. Yes.

  As mentioned above, although embodiment of this invention was described, embodiment is shown as an example and is not intending limiting the range of invention. The novel embodiment can be implemented in various other modes, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.

  The structure of the refrigerator 1 shown in FIG. 1 is an example, and an arbitrary structure can be adopted. For example, the door of the refrigerator compartment 2 of the refrigerator 1 may be a one-side opening type door.
