Embodiments of the present invention will be described below with reference to the drawings. Note that in the drawings, the same or corresponding parts will be given the same reference symbols and descriptions will not be repeated.

[Embodiment 1]
First, a cooling device 100 according to a first embodiment of the present invention will be described with reference to Fig. 1 and Fig. 2. Fig. 1 shows the cooling device 100 according to the embodiment of the present invention. Fig. 2 shows a schematic cross-section of the cooling device 100 of Fig. 1. The cooling device 100 includes a main body 2, a first refrigeration chamber 3, and a second refrigeration chamber 4. The cooling device 100 is, for example, a refrigerator. The cooling device 100 may also be, for example, a combination of a refrigerator and a freezer. The cooling device 100 may also be for home or commercial use.

The main body 2 has a box shape with a portion open. The main body 2 has a heat insulating material. The heat insulating material is, for example, a foam heat insulating material. The heat insulating material prevents the temperature outside the cooling device 100 from being transmitted to the inside of the main body 2. The heat insulating material also prevents the air inside the cooling device 100 from being transmitted to the outside of the cooling device 100.

The main body 2 has a bottom wall 21, a first side wall 22, a second side wall 23, a third side wall 24, and a top wall 25. The main body 2 also has a space 26 surrounded by the bottom wall 21, the first side wall 22, the second side wall 23, the third side wall 24, and the top wall 25.

The bottom wall 21 supports the first side wall 22, the second side wall 23, and the third side wall 24. The bottom wall 21 is located closer to the first direction D1 than the top wall 25. The first direction D1 indicates the direction from the top wall 25 to the bottom wall 21. The top wall 25 is supported by the first side wall 22, the second side wall 23, and the third side wall 24. The top wall 25 is located closer to the second direction D2 than the bottom wall 21. The second direction D2 indicates the opposite direction to the first direction D1.

The first side wall 22 to the third side wall 24 extend from the bottom wall 21 to the top wall 25. The first side wall 22 is located closer to the third direction D3 than the second side wall 23. The third direction D3 indicates the direction from the second side wall 23 to the first side wall 22. The second side wall 23 is located closer to the fourth direction D4 than the first side wall 22. The fourth direction D4 indicates the opposite direction to the third direction D3. The first side wall 22 and the second side wall 23 face each other. The third side wall 24 is located between the first side wall 22 and the second side wall 23. The third side wall 24 is located closer to the fifth direction D5 than the opening of the main body 2. The fifth direction D5 indicates the direction from the opening of the main body 2 to the third side wall 24. The sixth direction D6 indicates the opposite direction to the fifth direction D5. The third side wall 24 faces the opening of the main body 2.

As shown in FIG. 2, the main body 2 further includes a first insulating wall 27. The first insulating wall 27 suppresses the transfer of heat. Specifically, the first insulating wall 27 suppresses the transfer of heat from the first refrigerator chamber 3 to the second refrigerator chamber 4. Furthermore, the first insulating wall 27 suppresses the transfer of heat from the second refrigerator chamber 4 to the first refrigerator chamber 3.

The first insulating wall 27 also divides the space 26. That is, the first insulating wall 27 divides the space 26 into a first storage space 26A and a second storage space 26B. The first storage space 26A corresponds to the first refrigerator compartment 3. An object OB is stored in the first storage space 26A. The first storage space 26A is an example of a "storage space". The second storage space 26B corresponds to the second refrigerator compartment 4. An object OB is stored in the second storage space 26B. The second storage space 26B is an example of a "storage space".

As shown in Figures 1 and 2, the first refrigerator chamber 3 covers the first storage space 26A. Specifically, the first refrigerator chamber 3 covers the first storage space 26A that stores an object OB. The first refrigerator chamber 3 corresponds to an example of a "storage chamber". The object OB stored in the first storage space 26A of the first refrigerator chamber 3 is cooled. For example, in the first refrigerator chamber 3, the object OB is cooled to a temperature of 1 degree or higher. The object OB is, for example, food or drink. The first refrigerator chamber 3 is located closer to the second direction D2 than the second refrigerator chamber 4.

The second refrigerator chamber 4 covers the second storage space 26B. The second refrigerator chamber 4 covers the second storage space 26B that stores the object OB. The object OB stored in the second storage space 26B of the second refrigerator chamber 4 is cooled. For example, in the second refrigerator chamber 4, the object OB is cooled to a temperature of 1 degree or higher. The object OB is, for example, vegetables. The second refrigerator chamber 4 is a so-called vegetable chamber. The second refrigerator chamber 4 is located closer to the first direction D1 than the first refrigerator chamber 3. Note that in the second refrigerator chamber 4, the object OB may be cooled to a temperature of 0 degrees or lower. When the object OB is cooled to a temperature of 0 degrees or lower, the second refrigerator chamber 4 is a so-called freezer. The second refrigerator chamber 4 corresponds to an example of a "storage chamber".

The first refrigerator compartment 3 has a first door 31 and a first storage section 32.

The first storage section 32 stores an object OB in the first storage space 26A. The first storage section 32 has an opening 321. The first storage section 32 is box-shaped. The first storage section 32 has a partition plate 311 and a chilled chamber 310. The chilled chamber 310 stores an object OB. The temperature of the internal space of the chilled chamber 310 is lower than the temperature outside the chilled chamber 310 in the first storage space 26A.

The partition plate 311 divides the first storage space 26A. Specifically, the partition plate 311 divides the first storage space 26A into at least two spaces. The partition plate 311 that divides the first storage space 26A is used as a shelf. For example, the partition plate 311 is capable of placing an object OB thereon. In other words, the object OB is placed on the partition plate 311. The object OB is, for example, an apple. The object OB is, for example, a beverage sealed in a bottle.

The first storage section 32 also has a plurality of partition plates 311. The plurality of partition plates 311 divide the first storage space 26A into a plurality of sections. The plurality of partition plates 311 include a first partition plate 311A, a second partition plate 311B, a third partition plate 311C, and a fourth partition plate 311D. The first partition plate 311A is disposed at a position closest to the top wall 25. The second partition plate 311B is located closer to the first direction D1 than the first partition plate 311A. The second partition plate 311B is located between the first partition plate 311A and the third partition plate 311C. The third partition plate 311C is located closer to the first direction D1 than the second partition plate 311B. The third partition plate 311C is located between the second partition plate 311B and the fourth partition plate 311D. The fourth partition plate 311D is located on the first direction D1 side from the third partition plate 311C. The fourth partition plate 311D is also located at a position closest to the first insulating wall 27. The chilled chamber 310 is located between the fourth partition plate 311D and the first insulating wall 27.

The first door 31 can open and close the first storage section 32. Specifically, the first door 31 opens and closes the opening 321 of the first storage section 32.

The first door 31 rotates about a rotation axis extending along the first direction D1. The first door 31 rotates about the rotation axis to open and close the opening 321 of the first storage section 32. When the first door 31 is rotated in a direction away from the opening 321 of the first storage section 32, the first door 31 opens the opening 321. When the first door 31 is rotated in a direction approaching the opening 321 of the first storage section 32, the first door 31 closes the opening 321. The first door 31 is a substantially rectangular plate-shaped member.

As shown in FIG. 1, the first door 31 has a frame body 301 and a display unit 80. The frame body 301 supports the display unit 80. The display unit 80 displays an image. The display unit 80 covers more than half of the opening 321 of the first storage section 32. For example, the display unit 80 covers "more than 80%" of the opening 321 of the first storage section 32. In other words, the display unit 80 and the frame body 301 open and close the opening 321 of the first storage section 32. In other words, the display unit 80 constitutes the main body of the first door 31.

As shown in FIG. 2, the second refrigerator compartment 4 has a drawer body 41 and a second storage section 42. The second storage section 42 stores a part of the drawer body 41. The second storage section 42 is an example of a "storage section". The second storage section 42 has an opening 421. The second storage section 42 is box-shaped. The drawer body 41 can be freely pulled out and pushed into the second storage section 42. The drawer body 41 has a second door 411, a storage case 412, and a sliding member (not shown).

The second door 411 can open and close the opening 421 of the second storage section 42. When the drawer body 41 is pulled out from the second storage section 42, the opening of the second door 411 is open. When the drawer body 41 is pushed into the second storage section 42, the opening 421 of the second door 411 is closed. The second door 411 is a substantially rectangular plate-shaped member. The second door 411 is, for example, a front panel.

An object OB is stored in the storage case 412. The object OB stored in the storage case 412 is, for example, a cabbage. The object OB is, for example, a radish. The storage case 412 is, for example, a resin box. The storage case 412 is disposed on the rear surface of the second door 411. The drawer body 41 is separable from the second storage section 42. When the drawer body 41 is pulled out, the storage case 412 is pulled out from within the second storage section 42. When the drawer body 41 is pushed in, the storage case 412 is stored in the second storage section 42.

The slide member (not shown) guides the drawer body 41. For example, the slide member (not shown) guides the drawer body 41 in a direction in which the storage case 412 of the drawer body 41 is pulled out from inside the second storage section 42 to the outside. Also, for example, the slide member (not shown) guides the drawer body 41 in a direction in which the storage case 412 of the drawer body 41 is pushed from outside the second storage section 42 into the second storage section 42.

Next, the cooling device 100 according to this embodiment will be described in more detail with reference to Figs. 2 and 3. Fig. 3 is a schematic cross-sectional view of the cooling device 100 of Fig. 1 as viewed from the third side wall 24 side. As shown in Figs. 2 and 3, the cooling device 100 further includes a cooling unit 6 and an ion generating unit 9.

The cooling unit 6 cools storage compartments such as the first refrigerator compartment 3 and the second refrigerator compartment 4. More specifically, the cooling unit 6 cools at least one of the internal space of the first refrigerator compartment 3 and the internal space of the second refrigerator compartment 4.

As shown in Figures 2 and 3, the cooling section 6 has a refrigerant, a refrigerant pipe 601, a compression section 602, a condensation section 603, an expansion section 604, an evaporation section 605, a fan 606, a first cold air passage 610, a second cold air passage 620, and a damper 630.

The refrigerant transports heat. The refrigerant piping 601 guides the refrigerant. The refrigerant piping 601 connects the compression section 602, the condensation section 603, the expansion section 604, and the evaporation section 605. The refrigerant piping 601 circulates the refrigerant between the compression section 602, the condensation section 603, the expansion section 604, and the evaporation section 605.

The compression section 602 compresses the gaseous refrigerant. The refrigerant vaporized in the evaporation section 605 is sent to the compression section 602. The refrigerant compressed in the compression section 602 becomes high temperature and high pressure.

The condensation section 603 liquefies the gaseous refrigerant. The gaseous refrigerant that has become high temperature and high pressure in the compression section 602 is sent to the condensation section 603. The condensation section 603 dissipates heat from the gaseous refrigerant sent from the compression section 602. The refrigerant that has dissipated heat in the condensation section 603 becomes a liquid refrigerant at room temperature and high pressure.

The expansion section 604 allows liquid refrigerant to pass through. Liquid refrigerant at room temperature and high pressure is sent to the expansion section 604 from the condensation section 603. The expansion section 604 reduces the pressure on the refrigerant that has passed through it. As the pressure on the refrigerant decreases, the boiling point of the refrigerant decreases. In other words, the expansion section 604 reduces the temperature and pressure of the liquid refrigerant.

The evaporation section 605 vaporizes the refrigerant whose boiling point has been lowered. Low-temperature, low-pressure liquid refrigerant is sent from the expansion section 604 to the evaporation section 605. The refrigerant sent to the evaporation section 605 then vaporizes. When the refrigerant vaporizes, it absorbs heat from the surrounding air. In other words, the air around the evaporation section 605 is cooled as the refrigerant vaporizes. The vaporized refrigerant is sent again from the evaporation section 605 to the compression section 602.

The fan 606 rotates. The fan 606 blows air by rotating. The fan 606 blows cooled air. Specifically, the fan 606 blows air cooled by the evaporator 605. Hereinafter, the cooled air may be referred to as "cold air." The fan 606 blows the cold air to the first cold air passage 610 and the second cold air passage 620.

The first cold air passage 610 guides cold air. The first cold air passage 610 is arranged on the side of the third side wall 24 of the first refrigerator compartment 3. The first cold air passage 610 extends from the first insulating wall 27 to the top wall 25. The first cold air passage 610 guides cold air to the first refrigerator compartment 3. The first cold air passage 610 has multiple outlets 611.

The multiple outlets 611 include a first outlet 611A, a second outlet 611B, a third outlet 611C, a fourth outlet 611D, a fifth outlet 611E, and a sixth outlet 611F. The first outlet 611A guides cold air from the top wall 25 side. The first outlet 611A is located on the top wall 25 side of the first refrigerator compartment 3. The first outlet 611A discharges cold air from the top wall 25 side toward the first insulating wall 27. In other words, the first outlet 611A discharges cold air into the first refrigerator compartment 3. The first outlet 611A is a rectangular through hole.

The second outlet 611B guides the cold air between the top wall 25 and the first partition plate 311A. The cold air discharged from the second outlet 611B cools the object OB placed on the first partition plate 311A. The second outlet 611B is a rectangular through hole.

The third outlet 611C guides the cold air between the first partition plate 311A and the second partition plate 311B. The cold air discharged from the third outlet 611C cools an object OB placed on the second partition plate 311B. For example, the cold air discharged from the third outlet 611C cools fruit. The third outlet 611C is a rectangular through hole.

The fourth outlet 611D guides the cold air between the second partition plate 311B and the third partition plate 311C. The cold air discharged from the fourth outlet 611D cools the object OB placed on the third partition plate 311C. The fourth outlet 611D is a rectangular through hole.

The fifth outlet 611E guides the cold air between the third partition plate 311C and the fourth partition plate 311D. The cold air discharged from the fifth outlet 611E cools an object OB placed on the fourth partition plate 311D. For example, the cold air discharged from the fifth outlet 611E cools, for example, a beverage. The fifth outlet 611E is a rectangular through hole.

The sixth outlet 611F guides the cold air between the fourth partition plate 311D and the first insulating wall 27. Specifically, the sixth outlet 611F guides the cold air to the chilled chamber 310. The cold air discharged from the sixth outlet 611F cools the object OB placed in the chilled chamber 310. The sixth outlet 611F is a rectangular through hole.

The second cold air passage 620 guides the cold air. The second cold air passage 620 guides the cold air to the second refrigerator compartment 4. The second cold air passage 620 has a seventh outlet 621A.

The seventh outlet 621A guides the cold air to the second refrigerator compartment 4. Specifically, the seventh outlet 621A guides the cold air to the storage case 412 housed in the second refrigerator compartment 4. The cold air guided to the second refrigerator compartment 4 cools the object OB housed in the storage case 412. For example, as shown in FIG. 2, the cold air guided to the second refrigerator compartment 4 cools the vegetables housed in the storage case 412.

The damper 630 opens and closes the first cold air passage 610 and the second cold air passage 620. When the damper 630 is open, the first cold air passage 610 and the second cold air passage 620 communicate with each other. That is, when the damper 630 is open and the fan 606 blows cooled air, the cold air is guided from the second cold air passage 620 to the first cold air passage 610. On the other hand, when the damper 630 is closed, the first cold air passage 610 and the second cold air passage 620 do not communicate with each other. When the damper 630 is closed, the cold air is not guided from the second cold air passage 620 to the first cold air passage 610. The temperature of the first refrigerator compartment 3 and the second refrigerator compartment 4 is adjusted by opening and closing the damper 630. The damper 630 may have a temperature detection unit.

As shown in FIG. 2, the ion generating unit 9 generates ions. The ion generating unit 9 is attached to the top wall 25. The ion generating unit 9 is disposed inside the first cold air passage 610 and near the first outlet 611A. The ion generating unit 9 includes a pair of discharge electrodes. Each of the pair of discharge electrodes is a needle-shaped electrode. Each of the pair of discharge electrodes is formed, for example, from a metal having electrical conductivity.

The pair of discharge electrodes discharge. Specifically, when a high voltage is applied to the pair of discharge electrodes, the pair of discharge electrodes discharge to generate active species. The active species includes ions. For example, when a high voltage is applied to the pair of discharge electrodes, a corona discharge occurs between the discharge electrodes. Then, one of the pair of discharge electrodes discharges positive ions. The positive ions are cluster ions (H ⁺ (H ₂ O) _m (m is any positive number equal to or greater than zero)) in which a plurality of water molecules are clustered around a hydrogen ion (H ⁺ ). Furthermore, the other of the pair of discharge electrodes discharges negative ions. The negative ions are cluster ions (O ₂ - (H ₂ O) _n (n is any positive number equal to or greater than zero)) in which a plurality of water molecules are clustered around an oxygen ion (O ₂ - ).

The released positive and negative ions surround, for example, mold spores floating in the air, and cause a chemical reaction on the surface of the mold spores. The chemical reaction produces active species, hydroxyl radicals (.OH). The action of the hydroxyl radicals (.OH) then removes the mold spores.

The ion generating unit 9 is disposed, for example, in at least one of the first cold air passage 610 and the second cold air passage 620. Therefore, the ions generated by the ion generating unit 9 are contained in the wind generated by the fan 606. In other words, the ions are contained in the cold air. The cold air containing the ions is then discharged from the first outlet 611A to the eighth outlet 621B. As a result, the cold air containing the ions is sent to each of the first refrigerator compartment 3 and the second refrigerator compartment 4.

Next, the display unit 80 will be described in detail with reference to Figures 1 and 4. Figure 4 shows the display unit 80 of the cooling device 100.

The display unit 80 displays images. The images include at least one of still images and videos.

The display unit 80 includes a display unit 81 and an operation detection unit 82. The display unit 81 displays an environmental image. Hereinafter, the environmental image may be referred to as an "environmental image IM." Details of the environmental image IM will be described later. The display unit 81 covers at least a portion of the first storage space 26A. The display unit 81 is rectangular. The display unit 81 is capable of transmitting light from the first storage space 26A. The display unit 81 and the operation detection unit 82 are arranged to overlap. The user can view the environmental image IM displayed on the display unit 81 via the operation detection unit 82.

As shown in FIG. 4, the display unit 81 has a first display state. The first display state indicates a state in which light is transmitted from the first storage space 26A of the first storage unit 32. Also, as shown in FIG. 1, the display unit 81 has a second display state. The second display state indicates a state in which light transmittance is lower than that of the first display state. In other words, the display state of the display unit 81 switches between the first display state and the second display state. A state in which light transmittance is lower than that of the first display state typically indicates a state in which the user cannot view the first storage space 26A through the display unit 81 from outside the cooling device 100. Note that the state in which light transmittance is lower than that of the first display state may be a state in which the display unit 81 is transparent to an extent that it is more difficult for the user to view the first storage space 26A through the display unit 81 from outside the cooling device 100 than in the first display state.

The display unit 81 operates in a plurality of modes. The plurality of modes of the display unit 81 include a standby mode MS and a transmissive mode MP. The display unit 81 shown in FIG. 1 is in the standby mode MS. The standby mode MS indicates a mode in which the entire area AL of the display unit 81 is in the second display state. The entire area AL of the display unit 81 indicates an area including the entire display surface of the display unit 81. Therefore, in the standby mode MS, the user cannot see the first storage space 26A at all through the display unit 81 from outside the cooling device 100, or it is more difficult to see than in the first display state. The second display state is, for example, a state in which the backlight is turned off, a state in which a dark solid image is displayed in the entire area AL of the display unit 81, or a state in which the drive voltage is changed to reduce the transparency of the display unit 81.

The display unit 81 shown in FIG. 6 is in the transparent mode MP. The transparent mode MP indicates a mode in which a partial area VS of the display unit 81 is in the first display state. The partial area VS corresponds to an example of a "partial area". The partial area VS of the display unit 81 indicates a part of the entire area AL of the display unit 81. Therefore, in the transparent mode MP, the display unit 81 is transparent to an extent that, for example, a user can visually recognize the first storage space 26A through the partial area VS of the display unit 81 from outside the cooling device 100. The display unit 81 switches from the standby mode MS to the transparent mode MP in response to an operation from the user. As shown in FIG. 4, in the transparent mode MP, the partial area VS of the display unit 81 is transparent and see-through. "Transparent" means colorless transparent, translucent, or colored transparent. In other words, "transparent" is a state in which light is transmitted from the first storage space 26A of the first storage section 32, and indicates that the object OB located on the back side of the display section 81 can be seen from the front side of the display section 81.

Also, as shown in FIG. 1, the display unit 81 is not transparent when the environmental image IM is not displayed. The display unit 81 is, for example, a display panel such as a liquid crystal panel or an organic EL (Electro Luminescence) panel. The display unit 81 is formed, for example, of a transparent electrode, a transparent substrate, and a transparent material layer (for example, a liquid crystal layer or an organic EL layer). There are various principles for configuring the display unit 81 to be transparent, but the present invention can be applied regardless of the type of principle. For example, the display unit 81 is a transmissive liquid crystal panel. The display unit 80 may have a configuration in which a backlight is provided at a position that does not face the back surface of the display surface of the display unit 81. The backlight includes multiple light sources. The light source is, for example, an LED (Light Emitting Diode). For example, the backlight is arranged on the inner wall surface of the first refrigerator compartment 3 of the main body 2. For example, the backlight is arranged on the first side wall 22 to the third side wall 24 of the first refrigerator compartment 3. Specifically, the backlight is disposed on the first side wall 22 and the second side wall 23. The backlight may also be disposed on the first door 31. The backlight may also be disposed on each of the first side wall 22, the second side wall 23, the third side wall 24, and the first door 31. The backlight may also serve as both the backlight for the display unit 80 and the interior light for the first refrigerator compartment 3.

For example, the display unit 81 may be a self-luminous organic EL panel. Below, a transmissive liquid crystal panel will be used as an example of the display unit 81.

The operation detection unit 82 detects an operation position on the display unit 81. The operation position is a position operated by contact or non-contact, and may indicate a point or an area. The operation includes a touch operation. The touch operation includes a touch operation by contact or non-contact. For example, the operation detection unit 82 detects rubbing of a finger or a touch pen. The rubbing of a finger or a touch pen indicates, for example, a flick, a swipe, or a drag. The operation detection unit 82 may be an on-cell type or an in-cell type. The operation detection unit 82 is transparent. The operation position corresponds to, for example, the position of the environmental image IM displayed on the display unit 81.

The operation detection unit 82 can also function as an input unit. When the display unit 81 displays a software keyboard, various characters can be input to the operation detection unit 82. When the display unit 81 displays a menu key, instructions to execute various functions can be input to the operation detection unit 82. The detection result of the operation detection unit 82 is output to the control unit 11 as a detection signal. The cooling device 100 is operated based on the detection result of the operation detection unit 82.

Next, the cooling device 100 will be described in detail with reference to Figs. 4 and 5. Fig. 5 is a block diagram showing the control unit 11 of the cooling device 100 according to this embodiment. As shown in Figs. 4 and 5, the cooling device 100 further includes a detection unit 90, a control unit 11, and a memory unit 12.

The detection unit 90 detects a moving object. The detection unit 90 detects the moving object and outputs a detection signal of the moving object to the control unit 11. The moving object is, for example, a human being.

The detection unit 90 includes an imaging unit 91 and a distance measurement unit 92. The imaging unit 91 captures an image of the moving object and outputs an imaging signal as a detection signal to the control unit 11. The imaging unit 91 includes, for example, a camera. The distance measurement unit 92 detects the distance of the moving object relative to the display unit 80 and outputs a distance measurement signal as a detection signal to the control unit 11. The distance measurement unit 92 includes, for example, a distance measurement sensor.

The control unit 11 controls the display unit 81 so that the display unit 81 displays the environmental image IM. The control unit 11 is installed, for example, inside the top wall 25. The control unit 11 includes a processor such as a CPU (Central Processing Unit) or an ASIC (Application Specific Integrated Circuit), and a storage device. For example, the control unit 11 receives a signal output by the operation detection unit 82. The control unit 11 controls each element of the cooling device 100 based on the received signal. Specifically, as shown in FIG. 5, the control unit 11 controls each element of the cooling device 100 such as the cooling unit 6, the display unit 80, the detection unit 90, and the storage unit 12.

The memory unit 12 stores data and computer programs. For example, the memory unit 12 temporarily stores data necessary for each process of the control unit 11, and stores setting data for the display unit 80. The memory unit 12 includes storage devices (main storage device and auxiliary storage device), and includes, for example, a memory and a hard disk drive. The memory unit 12 may include removable media. The memory unit 12 stores an environmental image IM. The environmental image IM includes at least one of a still image and a video.

Next, the environmental image IM will be described with reference to Figures 5, 6, and 7. Figure 6 is a diagram showing a display unit 80 displaying a first environmental image IMA. Figure 7 is a diagram showing a display unit 80 displaying a second environmental image IMB.

As shown in FIG. 6, the display unit 81 has a portion VS of the screen that is transparent and another portion IVS of the screen that is opaque. In the portion VS of the screen, the screen is transparent, so the user can see objects OB1, OB2, and OB3. The portion VS of the screen corresponds to the range including the first partition plate 311A to the fourth partition plate 311D. In the other portion IVS of the screen, the screen is opaque, so the object OB cannot be seen. The other portion IVS of the screen is, for example, the portion that corresponds to the chilled compartment 310.

The display unit 81 also displays a first environmental image IMA. The first environmental image IMA represents the internal environment of the first refrigerator compartment 3.

The control unit 11 controls the display unit 81 to change the light transmittance of the display unit 81 when displaying the environmental image IM. In other words, the display unit 81 can display how the functions of the cooling device 100 act on the object OB contained in the first storage space 26A. As a result, the user can feel that the various functions of the cooling device 100 are being exerted.

When executing the transparent mode MP in which at least a partial area VS of the display unit 81 is in the first display state, the control unit 11 controls the display unit 81 to display the environmental image IM. That is, the environmental image IM is displayed by the transparent partial area VS of the display unit 81 so as to overlap with the interior of the first refrigerator compartment 3 and the object OB contained in the first refrigerator compartment 3. The user can check the interior of the first refrigerator compartment 3 even when the display unit 81 is displaying the environmental image IM. That is, the display unit 81 can display how the functions exerted by the cooling device 100 act on the object OB contained in the first refrigerator compartment 3. As a result, the transparent mode MP can give the user a sense that the various functions of the cooling device 100 are being exerted.

When executing standby mode MS in which the entire area AL of the display unit 81 is in the second display state, the control unit 11 controls the display unit 81 not to display the environmental image IM. As a result, the object OB stored in the first refrigerator compartment 3 can be hidden.

The first environmental image IMA will now be described with reference to FIG. 6. The first environmental image IMA is stored in the memory unit 12.

As shown in FIG. 6, the first environmental image IMA includes the flow of ions released into the first refrigerator compartment 3. In other words, the first environmental image IMA is an image that represents the flow of ions released into the first refrigerator compartment 3. The first environmental image IMA includes a first image IM1, a second image IM2, and a third image IM3. The first image IM1 is an icon indicating that ions are being released. The second image IM2 is an icon that typically indicates the position of the ions. A plurality of second images IM2 are displayed on the display unit 81. The third image IM3 is an icon that typically indicates the flow of ions. In addition, the first image IM1, the second image IM2, and the third image IM3 may be displayed semi-transparently on the display unit 81. By making the first image IM1, the second image IM2, and the third image IM3 transparent or semi-transparent, for example, the user can view the inside of the first refrigerator compartment 3 through the second image IM2.

The control unit 11 controls the display unit 81 to display the first environmental image IMA including the flow of ions released into the first refrigerator compartment 3. Therefore, the user can know the flow of ions in the first refrigerator compartment 3. As a result, the user can get the feeling that the first refrigerator compartment 3 is filled with ions and that the ions are moving due to the air current.

For example, the first environmental image IMA displayed on the display unit 81 includes a first image IM1, a second image IM2, and a third image IM3. For example, the second image IM2 is displayed at a position overlapping with the object OB1 or in the vicinity of the object OB. For example, by displaying the second image IM2 at a position overlapping with the object OB1, the user can recognize that ions have reached the object OB.

As shown in FIG. 7, the second environmental image IMB includes the flow of cold air discharged into the first refrigerator compartment 3. In other words, the second environmental image IMB is an image expressing the flow of cold air discharged into the first refrigerator compartment 3. The second environmental image IMB includes a fourth image IM4 and a fifth image IM5. The fourth image IM4 is an icon indicating that cold air is being discharged. The fifth image IM5 is an icon that diagrammatically indicates the flow of cold air. A plurality of fifth images IM5 are displayed on the display unit 81. The fourth image IM4 and the fifth image IM5 may be displayed transparently or semi-transparently on the display unit 81. By making the fourth image IM4 and the fifth image IM5 transparent or semi-transparent, for example, the user can view the inside of the first refrigerator compartment 3 through the fourth image IM4.

The control unit 11 controls the display unit 81 to display the second environmental image IMB including the flow of cold air released into the first refrigerator compartment 3. Therefore, the user can know the flow of cold air in the first refrigerator compartment 3. As a result, the user can feel that the cold air is filling the first refrigerator compartment 3 and cooling the object OB.

For example, the second environmental image IMB displayed on the display unit 81 includes a fourth image IM4 and a fifth image IM5. For example, the fifth image IM5 is displayed at a position overlapping with the object OB1 or in the vicinity of the object OB. For example, by displaying the fifth image IM5 at a position overlapping with the object OB1, the user can recognize that cold air has reached the object OB.

In addition, when displaying the environmental image IM on the display unit 81, the control unit 11 obtains one of the first environmental image IMA and the second environmental image IMB from the memory unit 12.

For example, as shown in FIG. 6, when the first environmental image IMA is displayed on the display unit 81, the control unit 11 acquires the first environmental image IMA from the memory unit 12. In the first embodiment, the first environmental image IMA is generated by simulating in advance the internal environment including the flow of ions in the first refrigerator compartment 3. Then, the first environmental image IMA generated by simulating in advance is stored in advance in the memory unit 12.

For example, as shown in FIG. 7, when the second environmental image IMB is displayed on the display unit 81, the control unit 11 acquires the second environmental image IMB from the storage unit 12. In the first embodiment, the second environmental image IMB is generated by simulating in advance the internal environment including the flow of cold air in the first refrigerator compartment 3. The second environmental image IMB generated by simulating in advance is then stored in advance in the storage unit 12.

In other words, the control unit 11 controls the display unit 81 to display an environmental image IM based on a simulation of the internal environment of the first refrigerator compartment 3. Therefore, the flow of ions in the first refrigerator compartment 3 generated based on the simulation, or the flow of cold air generated based on the simulation, can be displayed on the display unit 81. Thus, a specific flow of ions or flow of cold air can be displayed on the display unit 81. As a result, it becomes easier for the user to visualize the flow of ions or flow of cold air.

In the first embodiment, the display unit 81 separately displays the first environmental image IMA and the second environmental image IMB, but this is not limited to the above. For example, the display unit 81 may simultaneously display the first environmental image IMA and the second environmental image IMB. For example, as shown in FIG. 7 and FIG. 8, the display unit 81 simultaneously displays the first image IM1, the second image IM2, the third image IM3, the fourth image IM4, and the fifth image IM5. In other words, the internal environment of the first refrigerator compartment 3 is indicated by the flow of cold air and the flow of ions.

Next, the process executed by the control unit 11 will be described with reference to FIG. 8. FIG. 8 is a flowchart showing the process executed by the control unit 11. The process executed by the control unit 11 includes steps S101 to S105.

In step S101, the control unit 11 determines whether or not to display the environmental image IM. If the environmental image IM is not to be displayed (No in step S101), the process proceeds to step S105. If the environmental image IM is to be displayed (Yes in step S101), the process proceeds to step S102.

If the answer is Yes in step S101, in step S102, the control unit 11 executes a display process. The process proceeds to step S103. The display process will be described later with reference to FIG. 9.

In step S103, the control unit 11 controls the display unit 81 so that the display unit 81 displays the environmental image IM. The process proceeds to step S104.

In step S104, the control unit 11 controls the display unit 81 to display the environmental image IM and to set a partial area VS of the display unit 81 to the transparent mode MP. The process then ends.

If the answer is No in step S101, in step S105, the control unit 11 controls the display unit 81 so that the display unit 81 enters the standby mode MS. The process then ends.

Note that step S104 may be performed before step S103. Also, step S104 may be performed before step S101.

Next, the display process executed by the control unit 11 will be described with reference to FIG. 9. FIG. 9 is a flowchart showing the display process executed by the control unit 11. The display process shown in FIG. 9 includes steps S201 to S204.

In step S201, the control unit 11 determines whether the ion generating unit 9 generates ions. If the ion generating unit 9 does not generate ions (No in step S201), the process proceeds to step S204. If the ion generating unit 9 generates ions (Yes in step S201), the process proceeds to step S202.

If the answer is Yes in step S201, in step S202, the control unit 11 acquires a first environmental image IMA including the flow of ions released into the first refrigerator compartment 3 from the memory unit 12. The process proceeds to step S203.

In step S203, the control unit 11 acquires the second environmental image IMB including the flow of cold air released into the first refrigerator compartment 3 from the memory unit 12. The process returns to step S103 shown in FIG. 8.

If the answer is No in step S201, in step S204, the control unit 11 acquires the second environmental image IMB including the flow of cold air released into the first refrigerator compartment 3 from the memory unit 12. The process returns to step S103 shown in FIG. 8.

[Embodiment 2]
Next, a second embodiment of the present invention will be described with reference to Figs. 10 to 15. The cooling device 100 according to the second embodiment differs from the first embodiment mainly in that it has a detection unit S1. Below, differences between the second embodiment and the first embodiment will be described, and descriptions of parts that overlap with the first embodiment will be omitted. Fig. 10 is a schematic diagram showing a cross section of the cooling device 100 according to the second embodiment. Fig. 11 is a diagram showing a control unit 11 of the cooling device 100 according to the second embodiment.

As shown in Figs. 10 and 11, the cooling device 100 has a cooling section 6, an ion generating section 9, a display unit 80, a detection section 90, a memory section 12, and a control section 11. The cooling section 6 has a compression section 602, a condensation section 603, an expansion section 604, an evaporation section 605, a fan 606, a first cold air passage 610, a second cold air passage 620, and a damper 630. The display unit 80 includes a display section 81 and an operation detection section 82. The detection section 90 includes an imaging section 91 and a distance measurement section 92.

The cooling device 100 of the second embodiment further includes a detection unit S1. The detection unit S1 detects the presence of an object OB in the first storage space 26A. The detection unit S1 is disposed on the inner wall surface of the main body 2.

The detection unit S1 is, for example, an infrared sensor. The infrared sensor has a light-emitting unit and a light-receiving unit. The light-emitting unit emits light. Specifically, the light-emitting unit emits light in a direction from the inner wall surface of the main body unit 2 toward the partition plate 311. The emitted light is reflected by the object OB or the partition plate 311. The light-receiving unit receives the reflected light. Note that the detection unit S1 may be a transmission type sensor.

The detection unit S1 outputs a detection signal corresponding to the intensity of the received light to the control unit 11. For example, when an object OB is placed on the partition plate 311, the intensity of the received light changes. Specifically, when an object OB is placed on the partition plate 311, the intensity of the light reflected by the object OB differs from the intensity of the light reflected by the partition plate 311. In other words, the intensity of the light reflected by the object OB is the intensity of light according to the object OB. On the other hand, when an object OB is not placed on the partition plate 311, the intensity of the received light does not change.

The detection unit S1 may also be, for example, an imaging element. The imaging element captures an image of a predetermined imaging area. The predetermined imaging area is, for example, the partition plate 311. The imaging element generates data indicating the captured image and transmits it to the control unit 11. The imaging element is, for example, a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor.

The control unit 11, which has received the data indicating the captured image, acquires the change in the captured image, for example, by a background difference method. The control unit 11 may also acquire the change in the captured image by a frame difference method. For example, when an object OB is placed on the partition plate 311, the captured image changes. On the other hand, when an object OB is not placed on the partition plate 311, the captured image does not change.

Next, the third environmental image IMC displayed on the display unit 81 will be described with reference to Figs. 6 and 12. Fig. 12 is a diagram showing the display unit 80 displaying the third environmental image IMC. As shown in Fig. 12, the third environmental image IMC is displayed on the display unit 81. The third environmental image IMC represents the internal environment of the first refrigerator compartment 3. The third environmental image IMC is stored, for example, in the memory unit 12. The third environmental image IMC is displayed on the display unit 81 in an opaque state. Note that the third environmental image IMC may also be displayed on the display unit 81 in a semi-transparent state.

The third environmental image IMC is an image of the fourth partition 311D. The third environmental image IMC is a view of the fourth partition 311D from the third partition 311C. In other words, the third environmental image IMC is a view of the fourth partition 311D viewed from the first direction D1 side in a plan view. The third environmental image IMC includes the second image IM2, the sixth image IM6, the seventh image IM7, and the eighth image IM8. The sixth image IM6 is an image that diagrammatically shows the object OB3. The seventh image IM7 is an image that shows the fourth partition 411D. The eighth image IM8 is an image that shows the fifth outlet 611E.

As shown in FIG. 12, the sixth image IM6 is displayed near the eighth image IM8. Specifically, the object OB3 is disposed near the fifth outlet 611E. In other words, the object OB3 is obstructing the flow of ions ejected from the fifth outlet 611E. That is, the third environment image IMC shows that the flow of ions is changed by the object OB3. Specifically, the third environment image IMC shows that the amount of ions ejected from the fifth outlet 611E is decreasing. Note that the sixth image IM6 shown in FIG. 12 shows the object OB3 in a schematic manner, but it may be an image showing the object OB1. The sixth image IM6 may also be an image showing the object OB2. The seventh image IM7 shows the fourth partition plate 311D, but it may be an image showing any one of the first partition plate 311A to the third partition plate 311C.

In the second embodiment, the control unit 11 controls the display unit 81 to display an environmental image IM based on the detection result of the detection unit S1. Specifically, the control unit 11 controls the display unit 81 to display an environmental image IM indicating that the internal environment is changed by the object OB based on the detection result of the detection unit S1. As a result, the user can be notified that the internal environment is changed by the object OB.

The control unit 11 controls the display unit 81 to display a third environmental image IMC indicating that the flow of ions is being changed by the object OB based on the detection result of the detection unit S1. Therefore, the user can be notified that the flow of ions is being changed by the object OB. As a result, the user can be prompted to change the position of the object OB.

For example, as shown in FIG. 12, when the third environmental image IMC is displayed on the display unit 81, the control unit 11 acquires the third environmental image IMC from the memory unit 12. Specifically, when the detection result indicates that the detection unit S1 detects an object OB, the control unit 11 acquires the third environmental image IMC from the memory unit 12. Then, the control unit 11 controls the display unit 81 to display the third environmental image IMC. Therefore, a schematic flow of ions can be displayed on the display unit 81. In other words, an environmental image IM indicating that the flow of ions is being obstructed by the object OB can be displayed on the display unit 81. As a result, the user can be prompted to move the object OB to a position where it does not obstruct the flow of ions.

As shown in FIG. 6, when the first environmental image IMA is displayed on the display unit 81, the control unit 11 acquires the first environmental image IMA from the memory unit 12. Specifically, when the detection result indicates that the detection unit S1 does not detect the object OB, the control unit 11 acquires the first environmental image IMA from the memory unit 12. Then, the control unit 11 controls the display unit 81 to display the first environmental image IMA. Therefore, a schematic flow of ions can be displayed on the display unit 81. In other words, an environmental image IM showing the flow of ions inside the first refrigerator compartment 3 can be displayed on the display unit 81. As a result, the user can understand that ions are circulating inside the first refrigerator compartment 3.

Next, the fourth environmental image IMD displayed on the display unit 81 will be described with reference to Figs. 7 and 13. Fig. 13 is a diagram showing the display unit 80 displaying the fourth environmental image IMD. As shown in Fig. 13, the fourth environmental image IMD is displayed on the display unit 81. The fourth environmental image IMD represents the internal environment of the first refrigerator compartment 3. The fourth environmental image IMD is stored in the memory unit 12, for example. The fourth environmental image IMD is displayed on the display unit 81 in an opaque state. Note that the fourth environmental image IMD may also be displayed on the display unit 81 in a semi-transparent state.

The fourth environmental image IMD is an image of the fourth partition 311D. The fourth environmental image IMD is a view of the fourth partition 311D from the third partition 311C. In other words, the fourth environmental image IMD is a plan view of the fourth partition 311D from the first direction D1 side. The fourth environmental image IMD includes a fifth image IM5, a sixth image IM6, a seventh image IM7, and an eighth image IM8.

As shown in FIG. 13, the sixth image IM6 is displayed near the eighth image IM8. Specifically, the object OB3 is placed near the fifth outlet 611E. In other words, the object OB3 is blocking the flow of cold air discharged from the fifth outlet 611E. That is, the fourth environment image IMD shows that the flow of cold air is changed by the object OB3. Specifically, the fourth environment image IMD shows that the amount of cold air discharged from the fifth outlet 611E is decreasing. Note that the sixth image IM6 shown in FIG. 13 shows the object OB3 in a schematic manner, but it may be an image showing the object OB1. The sixth image IM6 may also be an image showing the object OB2. The seventh image IM7 shows the fourth partition plate 311D, but it may be an image showing any one of the first partition plate 311A to the third partition plate 311C.

In the second embodiment, the control unit 11 controls the display unit 81 to display a fourth environmental image IMD indicating that the flow of cold air is being changed by the object OB3 based on the detection result of the detection unit S1. Therefore, the user can be notified that the flow of cold air is being changed by the object OB. As a result, the user can be prompted to change the position of the object OB.

For example, as shown in FIG. 13, when the fourth environmental image IMD is displayed on the display unit 81, the control unit 11 acquires the fourth environmental image IMD from the memory unit 12. Specifically, when the detection result indicates that the detection unit S1 detects an object OB, the control unit 11 acquires the fourth environmental image IMD from the memory unit 12. The control unit 11 controls the display unit 81 to display the fourth environmental image IMD based on a simulation of the internal environment of the first refrigerator compartment 3. Therefore, a schematic flow of cold air can be displayed on the display unit 81. In other words, an environmental image IM indicating that the flow of cold air is being obstructed by the object OB can be displayed on the display unit 81. As a result, the user can be prompted to change the position of the object OB.

As shown in FIG. 7, when the second environmental image IMB is displayed on the display unit 81, the control unit 11 acquires the second environmental image IMB from the memory unit 12. Specifically, when the detection result indicates that the detection unit S1 does not detect the object OB, the control unit 11 acquires the second environmental image IMB from the memory unit 12. Then, the control unit 11 controls the display unit 81 to display the second environmental image IMB. Therefore, a schematic flow of cold air can be displayed on the display unit 81. In other words, an environmental image IM showing the flow of cold air inside the first refrigerator compartment 3 can be displayed on the display unit 81. As a result, the user can understand that cold air is circulating inside the first refrigerator compartment 3.

As shown in Figs. 10 to 13, the detection unit S1 includes multiple detection units. The multiple detection units include a first detection unit S11, a second detection unit S12, a third detection unit S13, and a fourth detection unit S14.

The first detection unit S11 detects an object OB placed on the first partition plate 311A. The first detection unit S11 is disposed on the inner wall on the top wall 25 side. In other words, the first detection unit S11 is disposed on the second direction D2 side of the first partition plate 311A.

For example, when the first detection unit S11 detects an object OB, the control unit 11 acquires the third environmental image IMC of the first partition board 311A stored in the memory unit 12. The control unit 11 then controls the display unit 81 so that the display unit 81 displays the third environmental image IMC. When the first detection unit S11 detects an object OB, the control unit 11 acquires the fourth environmental image IMD of the first partition board 311A stored in the memory unit 12. The control unit 11 then controls the display unit 81 so that the display unit 81 displays the fourth environmental image IMD. The control unit 11 may also control the display unit 81 so that the display unit 81 displays the third environmental image IMC and the fourth environmental image IMD.

The second detection unit S12 detects an object OB placed on the second partition plate 311B. The second detection unit S12 is disposed on the inner wall on the first partition plate 311A side. In other words, the second detection unit S12 is disposed on the second direction D2 side of the second partition plate 311B.

For example, when the second detection unit S12 detects an object OB, the control unit 11 acquires a third environmental image IMC of the second partition board 311B stored in the memory unit 12. Also, when the second detection unit S12 detects an object OB, the control unit 11 acquires a fourth environmental image IMD of the second partition board 311B stored in the memory unit 12.

The third detection unit S13 detects an object OB placed on the third partition plate 311C. The third detection unit S13 is disposed on the inner wall on the second partition plate 311B side. In other words, the third detection unit S13 is disposed on the second direction D2 side of the third partition plate 311C.

For example, when the third detection unit S13 detects an object OB, the control unit 11 acquires a third environmental image IMC of the third partition board 311C stored in the memory unit 12. Also, when the third detection unit S13 detects an object OB, the control unit 11 acquires a fourth environmental image IMD of the third partition board 311C stored in the memory unit 12.

The fourth detection unit S14 detects an object OB placed on the fourth partition plate 311D. The fourth detection unit S14 is disposed on the inner wall on the third partition plate 311C side. In other words, the fourth detection unit S14 is disposed on the second direction D2 side of the fourth partition plate 311D.

For example, when the fourth detection unit S14 detects an object OB, the control unit 11 acquires a third environmental image IMC of the fourth partition plate 311D stored in the memory unit 12. Also, when the fourth detection unit S14 detects an object OB, the control unit 11 acquires a fourth environmental image IMD of the fourth partition plate 311D stored in the memory unit 12.

Next, the display process executed by the control unit 11 according to the second embodiment will be described with reference to Figs. 14 and 15. Fig. 14 is a diagram showing the display process executed by the control unit 11 according to the second embodiment. Fig. 15 is a diagram showing the display process executed by the control unit 11 according to the second embodiment. The display process executed by the control unit 11 according to the second embodiment includes steps S301 to S313. The display process corresponds to step S102 shown in Fig. 8.

In step S301, the control unit 11 determines whether the ion generating unit 9 generates ions. If the ion generating unit 9 does not generate ions (No in step S301), the process proceeds to step S311. If the ion generating unit 9 generates ions (Yes in step S301), the process proceeds to step S302.

If the answer is Yes in step S301, then in step S302, the control unit 11 determines whether the detection unit S1 detects an object OB. The control unit 11 determines whether the detection unit S1 has detected the presence of an object OB in the first storage space 26A. If the detection unit S1 does not detect an object OB (No in step S302), the process proceeds to step S306. If the detection unit S1 detects an object OB (Yes in step S302), the process proceeds to step S303.

If the answer is Yes in step S302, in step S303, the control unit 11 acquires from the memory unit 12 a third environmental image IMC indicating that the flow of ions is changed by the object OB. The process proceeds to step S304.

In step S304, the control unit 11 acquires from the memory unit 12 a fourth environmental image IMD that indicates that the flow of cold air is being changed by the object OB. The process returns to step S103 shown in FIG. 8.

If the answer is No in step S302, in step S306, the control unit 11 acquires a first environmental image IMA including the flow of ions released into the first refrigerator compartment 3 from the memory unit 12. The process proceeds to step S307.

Next, a third embodiment will be described with reference to Figs. 12, 13, and 16 to 20. The cooling device 100 according to the third embodiment is mainly different in that the control unit 11 has an execution unit 111 and a generation unit 112. Below, the differences between the third embodiment and the first and second embodiments will be described, and the description of the overlapping parts with the first and second embodiments will be omitted. Fig. 16 is a diagram showing the control unit 11 of the cooling device 100 according to the third embodiment.

As shown in FIG. 16, the cooling device 100 has a cooling section 6, a detection section S1, an ion generating section 9, a display unit 80, a detection section 90, a memory section 12, and a control section 11. The cooling section 6 has a compression section 602, a condensation section 603, an expansion section 604, an evaporation section 605, a fan 606, a first cold air passage 610, a second cold air passage 620, and a damper 630. The detection section S1 includes a first detection section S11, a second detection section S12, a third detection section S13, and a fourth detection section S14. The display unit 80 includes a display section 81 and an operation detection section 82. The detection section 90 includes an imaging section 91 and a distance measurement section 92.

The control unit 11 of the cooling device 100 of the third embodiment has an execution unit 111 and a generation unit 112. The control unit 11 functions as the execution unit 111 and the generation unit 112 by executing a control program.

The execution unit 111 simulates the internal environment of the first refrigerator compartment 3 based on the detection result of the detection unit S1. For example, the execution unit 111 calculates the distance between the object OB and the first detection unit S11 based on the detection result of the detection unit S1. Then, based on the calculation result, the execution unit 111 simulates the flow of ions or the flow of cold air.

For example, the execution unit 111 simulates the internal space of the first refrigerator compartment 3 based on the detection result of the first detection unit S11. The detection result of the first detection unit S11 includes the position of the object OB on the first partition plate 311A. In other words, the simulation result differs depending on the position of the object OB.

For example, the execution unit 111 also simulates the internal space of the first refrigerator compartment 3 based on the detection results of the second detection unit S12. The detection results of the second detection unit S12 include the positions of the objects OB1 and OB2 on the second partition plate 311B. In other words, the simulation results differ depending on the positions of the objects OB1 and OB2.

For example, the execution unit 111 also simulates the internal space of the first refrigerator compartment 3 based on the detection result of the third detection unit S13. The detection result of the third detection unit S13 includes the position of the object OB on the third partition plate 311C. In other words, the simulation result differs depending on the position of the object OB.

For example, the execution unit 111 also simulates the internal space of the first refrigerator compartment 3 based on the detection result of the fourth detection unit S14. The detection result of the fourth detection unit S14 includes the position of the object OB3 on the fourth partition plate 311D.

The generation unit 112 generates an environmental image IM based on the simulation. Specifically, the generation unit 112 generates an environmental image IM based on the simulation executed by the execution unit 111. For example, the generation unit 112 generates a third environmental image IMC as shown in FIG. 12 based on the simulation executed by the execution unit 111. For example, the generation unit 112 generates a fourth environmental image IMD as shown in FIG. 13 based on the simulation executed by the execution unit 111.

Next, the fifth environmental image IME displayed on the display unit 81 will be described with reference to Figs. 12 and 17. Fig. 17 is a diagram showing the display unit 80 displaying the fifth environmental image IME. As shown in Fig. 17, the fifth environmental image IME is displayed on the display unit 81. The fifth environmental image IME represents the internal environment of the first refrigerator compartment 3. Specifically, the fifth environmental image IME is an environmental image IM generated by the generation unit 112 based on a simulation executed by the execution unit 111. The fifth environmental image IME generated by the generation unit 112 is stored in the memory unit 12. The fifth environmental image IME is displayed on the display unit 81 in an opaque state. Note that the fifth environmental image IME may also be displayed on the display unit 81 in a semi-transparent state.

The fifth environmental image IME is an image of the fourth partition 311D. The fifth environmental image IME is a view of the fourth partition 311D from the third partition 311C. The fifth environmental image IME includes a second image IM2, a sixth image IM6, a seventh image IM7, and an eighth image IM8.

Compared to the sixth image IM6 shown in FIG. 12, the sixth image IM6 shown in FIG. 17 is displayed at a position farther away from the eighth image IM8. Specifically, compared to FIG. 12, the object OB3 is disposed farther away from the fifth outlet 611E. In other words, the object OB3 does not obstruct the flow of ions ejected from the fifth outlet 611E. Note that the sixth image IM6 shown in FIG. 16 shows the object OB3 in a schematic manner, but it may be an image showing the object OB1. The sixth image IM6 may also be an image showing the object OB2. Also, the seventh image IM7 shows the fourth partition plate 311D, but it may be an image showing any one of the first partition plate 311A to the third partition plate 311C.

Next, the sixth environmental image IMF displayed on the display unit 81 will be described with reference to Figs. 13 and 18. Fig. 18 is a diagram showing the display unit 80 displaying the sixth environmental image IMF. As shown in Fig. 18, the sixth environmental image IMF is displayed on the display unit 81.

The sixth environmental image IMF represents the internal environment of the first refrigerator compartment 3. Specifically, the sixth environmental image IMF is an environmental image IM generated by the generation unit 112 based on a simulation executed by the execution unit 111. The sixth environmental image IMF generated by the generation unit 112 is stored in the memory unit 12. The sixth environmental image IMF is displayed on the display unit 81 in an opaque state. The sixth environmental image IMF may also be displayed on the display unit 81 in a semi-transparent state.

The sixth environmental image IMF is an image of the fourth partition 311D. The sixth environmental image IMF is a view of the fourth partition 311D from the third partition 311C. The sixth environmental image IMF includes a fifth image IM5, a sixth image IM6, a seventh image IM7, and an eighth image IM8.

Compared to the sixth image IM6 shown in FIG. 13, the sixth image IM6 shown in FIG. 18 is displayed at a position farther away from the eighth image IM8. Specifically, compared to FIG. 13, the object OB3 is placed farther away from the fifth outlet 611E. In other words, the object OB3 does not obstruct the flow of cool air discharged from the fifth outlet 611E. Note that the sixth image IM6 shown in FIG. 18 shows the object OB3 in a schematic manner, but it may be an image showing the object OB1. The sixth image IM6 may also be an image showing the object OB2. Also, the seventh image IM7 shows the fourth partition plate 311D, but it may be an image showing any one of the first partition plate 311A to the third partition plate 311C.

For example, as shown in Figures 12 and 13, when the fourth detection unit S14 detects an object OB3 near the fifth outlet 611E, the fourth detection unit S14 outputs a detection result indicating that the object OB3 is located near the fifth outlet 611E to the execution unit 111.

Next, the execution unit 111 simulates the flow of ions changed by the object OB3 based on the detection result. The simulation executed by the execution unit 111 is then output to the generation unit 112. Furthermore, the generation unit 112 generates a third environmental image IMC shown in FIG. 12 based on the simulation executed by the execution unit 111.

The execution unit 111 also simulates the flow of cold air changed by the object OB3 based on the detection result. The simulation executed by the execution unit 111 is then output to the generation unit 112. Furthermore, the generation unit 112 generates a fourth environmental image IMD shown in FIG. 13 based on the simulation executed by the execution unit 111.

Also, for example, as shown in Figures 17 and 18, if the fourth detection unit S14 does not detect an object OB3 near the fifth outlet 611E, the fourth detection unit S14 outputs a detection result indicating that the object OB3 is not located near the fifth outlet 611E to the execution unit 111.

Next, the execution unit 111 simulates the flow of ions changed by the object OB3 based on the detection result. The simulation executed by the execution unit 111 is then output to the generation unit 112. Furthermore, the generation unit 112 generates a fifth environmental image IME shown in FIG. 17 based on the simulation executed by the execution unit 111.

The execution unit 111 also simulates the flow of cold air changed by the object OB3 based on the detection result. The simulation executed by the execution unit 111 is then output to the generation unit 112. Furthermore, the generation unit 112 generates a sixth environmental image IMF shown in FIG. 18 based on the simulation executed by the execution unit 111.

The control unit 11 of the third embodiment controls the display unit 81 to display the environmental image IM generated by the generation unit 112. Thus, a simulation is performed based on the arrangement of the object OB contained in the first refrigerator compartment 3. As a result, the user can know whether the object OB is substantially or actually blocking the flow of ions or cold air.

Next, the display processing executed by the control unit 11 according to the third embodiment will be described with reference to Figs. 19 and 20. Fig. 19 is a flowchart showing the display processing executed by the control unit 11 according to the third embodiment. Fig. 20 is a flowchart showing the display processing executed by the control unit 11 according to the third embodiment. The display processing executed by the control unit 11 according to the third embodiment includes steps S401 to S415. Steps S401, S402, and S411 correspond to steps S301, S302, and S311 shown in Fig. 14, and therefore descriptions thereof will be omitted. The display processing corresponds to step S102 shown in Fig. 8.

If the answer is Yes in step S402, in step S403, the execution unit 111 simulates the internal space of the first refrigerator compartment 3 based on the detection result of the detection unit S1 indicating that an object OB has been detected. The process proceeds to step S404.

In step S404, the generation unit 112 generates a third environmental image IMC that indicates that the flow of ions is changed by the object OB, based on the simulation performed by the execution unit 111. The process proceeds to step S405.

In step S405, the control unit 11 generates a fourth environmental image IMD indicating that the flow of cold air is changed by the object OB based on the simulation performed by the execution unit 111. The process returns to step S103 shown in FIG. 8.

If the answer is No in step S402, in step S406, the execution unit 111 simulates the internal space of the first refrigerator compartment 3 based on the detection result of the detection unit S1 indicating that the object OB is not detected. The process proceeds to step S407.

In step S407, the generation unit 112 generates a fifth environmental image IME including the flow of ions based on the simulation performed by the execution unit 111. The process proceeds to step S408.

In step S408, the control unit 11 generates a sixth environmental image IMF including the flow of cold air based on the simulation performed by the execution unit 111. The process returns to step S103 shown in FIG. 8.

If the answer is Yes in step S411, in step S412, the execution unit 111 simulates the internal space of the first refrigerator compartment 3 based on the detection result of the detection unit S1 indicating that an object OB has been detected. The process proceeds to step S413.

The above describes the embodiments of the present invention with reference to the drawings. However, the present invention is not limited to the above embodiments, and can be implemented in various forms without departing from the gist of the present invention. In addition, various inventions can be formed by appropriately combining multiple components disclosed in each of the above embodiments. For example, some components may be deleted from all components shown in the embodiments. Furthermore, components from different embodiments may be appropriately combined. The drawings are mainly schematic views of each component for ease of understanding, and the thickness, length, number, spacing, etc. of each component shown in the drawings differ from the actual ones due to the convenience of drawing. In addition, the speed, material, shape, dimensions, etc. of each component shown in the above embodiments are merely examples and are not particularly limited, and various modifications are possible within a range that does not substantially deviate from the configuration of the present invention.

(1) In the cooling device 100 of this embodiment, the display unit 80 may have an audio input unit. Audio is input to the audio input unit. Specifically, audio spoken by the user is input to the audio input unit. The audio input unit is, for example, a microphone. The microphone is an example of a sound collection device. The audio input to the audio input unit is transmitted to the control unit 11.

The control unit 11 then extracts a keyword based on the voice input from the voice input unit. Specifically, the control unit 11 converts the user's voice into a digital signal. The control unit 11 then generates text information corresponding to the user's voice based on the digital signal. Furthermore, the control unit 11 determines whether or not the text information indicating the voice input from the voice input unit matches a voice pattern stored in the storage unit 12. The control unit 11 then extracts the text information indicating the voice that matches the voice pattern as a keyword. Furthermore, the control unit 11 controls each part of the cooling device 100 based on the extracted keyword.

(2) In the cooling device 100 of this embodiment, the control unit 11 may display an image on the display unit 81 based on the detection result of the detection unit 90. For example, when the detection unit 90 detects a moving object, the control unit 11 displays the environmental image IM on the display unit 81. In other words, when a person is near the cooling device 100, the control unit 11 displays the environmental image IM on the display unit 81. On the other hand, when the detection unit 90 does not detect a moving object, the control unit 11 does not display the environmental image IM on the display unit 81. In other words, when there is no person near the cooling device 100, the control unit 11 does not display the environmental image IM on the display unit 81. Therefore, based on the detection result of the detection unit 90, it is possible to determine whether or not to display the environmental image IM on the display unit 81. As a result, the user can feel that the various functions of the cooling device 100 are being performed at the appropriate time.

(3) In the cooling device 100 of this embodiment, the multiple partition plates 311 include the first partition plate 311A to the fourth partition plate 311D, but this is not limited to this. For example, the multiple partition plates 311 may include the first partition plate 311A and the fourth partition plate 311D. Also, there may be only the fourth partition plate 311D. The multiple partition plates 311 can be removed from the first storage section 32.

The inner wall surfaces of the first storage section 32 are painted the same color. The color of the inner wall surfaces of the first storage section 32 is, for example, white. By making the wall surfaces white, the light emitted by the backlight of the display unit 80 is reflected. Therefore, the inner wall surfaces of the first storage section 32 can be used as a reflective member for the backlight. Furthermore, by making the wall surfaces white, the light emitted from the backlight can be efficiently reflected. As a result, it is possible to prevent the environmental image IM displayed on the display section 81 from becoming difficult to see.

The color of the multiple partitions 311 may be the same as the color of the interior wall surface of the first storage section 32. In other words, the color of the multiple partitions 311 is white. Therefore, the partitions 311 reflect the light emitted from the backlight of the display unit 80. As a result, it is possible to prevent the environmental image IM displayed on the display section 81 from becoming difficult to see.

(4) In the cooling device 100 of this embodiment, the display unit 80 is disposed on the first door 31, but this is not limited to the above. For example, the display unit 80 may be disposed on the second door 411. Also, for example, the display unit 80 may be disposed on the first side wall 22 of the main body 2. Also, for example, the display unit 80 may be disposed on the second side wall 23 of the main body 2.

(5) In the cooling device 100 of this embodiment, the control unit 11 changes the brightness of the backlight depending on whether the first door 31 is open or closed. In other words, the control unit 11 controls the brightness of the backlight depending on whether the first door 31 is open or closed. For example, the cooling device 100 has an opening/closing sensor that detects whether the first door 31 is blocking the opening 321 of the first storage section 32. The opening/closing sensor detects the blocking of the first storage section 32. The control unit 11 then controls the backlight based on the detection result of the opening/closing sensor. Specifically, when the detection result indicates that the first door 31 is not blocking the opening 321 of the first storage section 32, the control unit 11 controls the brightness of the backlight so that the inside of the first storage section 32 can be seen. Specifically, for example, when the detection result indicates that the first door 31 is blocking the opening 321, the control unit 11 controls the brightness of the backlight so that the environmental image IM of the display unit 81 can be seen. Therefore, when the first door 31 opens the opening 321, the user can easily check the first storage space 26A. When the first door 31 closes the opening 321 of the first storage section 32, the user can easily check the display unit 81. As a result, the brightness of the object that the user wants to check can be increased, making it easier for the user to check the object.

In addition, when the detection result indicates that the first door 31 is not blocking the opening 321 of the first storage unit 32, the control unit 11 makes the brightness on the display unit 81 side smaller than the brightness on the first storage unit 32 side. In addition, when the detection result indicates that the first door 31 is blocking the opening 321 of the first storage unit 32, the control unit 11 makes the brightness on the display unit 81 side larger than the brightness on the first storage unit 32 side. Therefore, when the first door 31 opens the opening 321 of the first storage unit 32, it is easy for the user to check the inside of the first storage unit 32. When the first door 31 blocks the opening 321 of the first storage unit 32, it is easy for the user to check the display unit 81. As a result, the brightness of the object that the user wants to check can be increased, making it easier to check the object.

(6) The cooling device 100 of this embodiment may perform wireless power supply between the main body 2 and the display unit 80. Specifically, the cooling device 100 may have a power supply unit, a power receiving unit, a first communication unit, and a second communication unit.

The power supply unit supplies power to the power receiving unit. The power supply unit supplies power to the display unit 80 via the power receiving unit. The power supply unit is disposed on the top wall 25 of the main body 2. The power supply unit is connected to the control unit 11 by a signal line. The power supply unit has an oscillation coil.

The power receiving unit receives power supplied from the power supply unit. The power receiving unit is disposed on the first door 31. The power receiving unit is connected to the display unit 80 via a signal line. The power receiving unit has a power receiving coil and a rectifier circuit.

When the first door 31 closes the first storage section 32, the power receiving section faces the power supply section. Specifically, when the first door 31 closes the first storage section 32, the power receiving coil of the power receiving section faces the oscillator coil of the power supply section. When the power receiving coil and the oscillator coil face each other, electromagnetic induction coupling occurs between the power receiving coil and the oscillator coil. Then, an alternating current is induced in the power receiving coil. Therefore, power is supplied to the display unit 80. As a result, power can be supplied to the display unit 80 in a non-contact (wireless) manner.

The first communication unit communicates information with the second communication unit. The first communication unit controls the display unit 80 via the second communication unit. The first communication unit is disposed on the top wall 25 of the main body unit 2. The first communication unit is connected to the control unit 11 by a signal line. The first communication unit has, for example, an infrared light receiving unit and an infrared light emitting unit.

The second communication unit communicates information with the first communication unit. The second communication unit transmits a signal received from the first communication unit to the display unit 80. The second communication unit is disposed on the first door 31. The second communication unit is connected to the display unit 80 by a signal line. The second communication unit has, for example, an infrared receiving unit and an infrared emitting unit.

When the first door 31 closes the first storage section 32, the first communication section faces the second communication section. Specifically, when the first door 31 closes the first storage section 32, the infrared light receiving section of the first communication section faces the infrared light emitting section of the second communication section. Also, when the first door 31 closes the first storage section 32, the infrared light emitting section of the first communication section faces the infrared light receiving section of the second communication section. In other words, data is exchanged between the control section 11 and the display unit 80.

The method of information communication between the control unit 11 and the display unit 80 is infrared communication, but is not limited to this. The power supply method and information communication method are wireless, but are not limited to this. For example, the power supply method and the information communication method may be connected by wire.

(7) The display unit 80 of this embodiment may have a battery. The power supplied to the display unit 80 is stored in the battery.

(8) The execution unit 111 of this embodiment may simulate the internal environment including the temperature distribution inside the first refrigerator compartment 3 based on the detection result of the detection unit S1. Then, the generation unit 112 generates an environmental image IM including the temperature distribution inside the first refrigerator compartment 3 based on the simulation executed by the execution unit 111. Furthermore, the control unit 11 controls the display unit 81 to display the environmental image IM including the temperature distribution inside the first refrigerator compartment 3 generated by the generation unit 112. Therefore, the temperature distribution inside the first refrigerator compartment 3 can be notified to the user. As a result, the user can be prompted to change the position of the object OB so that the temperature distribution becomes uniform.

Specifically, for example, the execution unit 111 simulates the temperature distribution in the first partition plate 311A of the first refrigerator compartment 3. The execution unit 111 simulates the temperature distribution in the second partition plate 311B of the first refrigerator compartment 3. The execution unit 111 simulates the temperature distribution in the third partition plate 311C of the first refrigerator compartment 3. The execution unit 111 simulates the temperature distribution in the fourth partition plate 311D of the first refrigerator compartment 3.

Then, for example, the generation unit 112 generates an environmental image IM including a temperature distribution at the first partition plate 311A based on the simulation executed by the execution unit 111. For example, the generation unit 112 generates an environmental image IM including a temperature distribution at the second partition plate 311B based on the simulation executed by the execution unit 111. For example, the generation unit 112 generates an environmental image IM including a temperature distribution at the third partition plate 311C based on the simulation executed by the execution unit 111. For example, the generation unit 112 generates an environmental image IM including a temperature distribution at the fourth partition plate 311D based on the simulation executed by the execution unit 111.

(9) In the first embodiment, the first environmental image IMA is described as an image generated by performing a simulation in advance, but this is not limited to this. Also, the second environmental image IMB is described as an image generated by performing a simulation in advance, but this is not limited to this. In other words, the storage unit 12 in the first embodiment may store the first environmental image IMA and the second environmental image IMB that are generated without performing a simulation.

(10) The environmental image IM may include information about the smell. For example, the cooling device 100 has an odor sensor (not shown) that detects the smell, and the environmental image IM about the smell is generated based on the detection result of the odor sensor. Also, for example, the environmental image IM about the smell may change in accordance with the release of ions.
