Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.
<First Embodiment>

<Outline of refrigerator>
In the present embodiment, as an example of the present invention, a configuration in which the door containing storage system of one aspect of the present invention is applied to a beverage supply system will be described as an example. In the present embodiment, an example of a configuration in which the beverage supply system is built in the refrigerator will be described. However, the beverage supply system of one aspect of the present invention does not necessarily have to be built in the refrigerator. First, the outline | summary of the refrigerator 1 in which the drink supply system 10 concerning this Embodiment is mounted is demonstrated. FIG. 1 is a front view showing a refrigerator 1 equipped with a beverage supply system 10 according to the present embodiment.

Refrigerator 1 according to the present embodiment is equipped with a refrigerator compartment at the top and a freezer compartment at the bottom. As shown in FIG. 1, the refrigerator 1 has four doors. Specifically, a double door (right door) 2 and a door (left door) 3 are provided in the upper refrigerator compartment. Similarly, a double door is also provided in the lower freezer compartment. Moreover, the handle 4 is each provided in each door of the refrigerator. And the drink supply system 10 is mounted in the door 2 of the right side seeing from the front for refrigerator compartments of the refrigerator 1.

However, the refrigerator 1 on which the beverage supply system 10 is mounted may have fewer than four doors, may have more than four doors, and the refrigerator compartment may be a lower stage or a middle stage. It may be arranged in.

FIG. 1 shows a state when the beverage supply system 10 is not used. As shown in FIG. 1, the rotating door 21 of the beverage supply system 10 is located on the front side of the refrigerator 1 when not in use. That is, the water injection mechanism of the beverage supply system 10 is disposed on the back side of the rotary door 21 (door) and is not visible. An object detection sensor 22 is provided in the vicinity of the rotary door 21.

Further, a display panel 23 is provided on the front surface of the refrigerator 1. Although the position of the display panel 23 is not particularly limited, in the present embodiment, the display panel 23 is disposed on the surface of the door 3 on the left side of the refrigerator compartment. The display panel 23 is a touch panel display device and can also function as an operation panel (operation unit). Therefore, the user can change the operation mode of the refrigerator 1 or the operation mode of the beverage supply system 10 from the operation panel.

The object detection sensor 22 detects that the user's hand or the like using the beverage supply system 10 has approached or the user's hand has touched the sensor. In addition, the object detection sensor 22 is comprised with an electrostatic capacitance type non-contact sensor, for example. For example, the object detection sensor 22 may be a proximity sensor whose output voltage changes according to the distance from the object to be detected. Thereby, it can suppress that a hand and a glass contact the surface of the door 2 of the refrigerator 1, and dirt adheres. However, the present invention is not limited to this, and the detection unit that detects whether or not an object exists in the vicinity of the rotary door may be configured by a contact sensor, a push button, or the like.

In the display panel 23, a human sensor 24 is provided. The human sensor 24 detects whether a person is present around the refrigerator 1. The human sensor 24 is configured by a non-contact sensor such as a photoelectric sensor, for example.

The beverage supply system 10 is configured such that when the object detection sensor 22 detects a user's hand or the like, the rotary door 21 rotates in the horizontal direction and the water injection mechanism appears in the front (see FIG. 4). When the revolving door 21 rotates, as shown in FIGS. 2 and 3, the bottom portion 15 (water receiver), the back plate 17, the side plate 19, the water injection lever (lever) 32, etc. constituting the beverage supply system 10 appear in the front. .

And based on the user's operation, the water in the water tank 70 cooled in the refrigerator compartment is discharged from the water injection port 31 (discharge port of the discharge unit). In the present embodiment, for example, when the user pushes the water injection lever 32 toward the back plate 17 with a container such as a glass (water supply member), water is supplied into the glass. In the present embodiment, an opening 32 a is formed at a substantially central portion of the water injection lever 32.

In addition, the beverage supply system 10 of this embodiment includes a sterilization unit 50. When the revolving door 21 is in the open state, the sterilization unit 50 exists on the back side of the back plate 17 and the revolving door 21 (see FIG. 7). That is, when the rotary door 21 is in the open state, the rotary door 21 and the back plate 17 are interposed between the water inlet 31 and the sterilization unit 50. Therefore, when the revolving door 21 is in the open state, the sterilization unit 50 is not visible from the front, but in FIG. 2, the sterilization unit 50 is indicated by a broken line for convenience. A more detailed configuration of the beverage supply system 10 including the sterilization unit 50 will be described later.

Although the installation location of the object detection sensor 22 is not particularly limited, in the present embodiment, the object detection sensor 22 is disposed on the left side of the beverage supply system 10. And if the object detection sensor 22 detects a user, as shown to Fig.4 (a)-(c), the rotation door 21 of the drink supply system 10 will rotate counterclockwise, and a water injection mechanism will appear from the left side. Thereby, the user who has the glass G etc. in his / her hand can easily bring his hand close to the water injection mechanism by moving his / her hand from the vicinity of the front side of the object detection sensor 22.

According to this configuration, the convenience of the beverage supply system is further improved. In addition, when the rotation door of a drink supply system rotates clockwise, it is preferable to provide an object detection sensor on the right side of a drink supply system. Thus, it is preferable that the object detection sensor is arrange | positioned according to the rotation direction of a drink supply system.

The arrangement position of the beverage supply system in the refrigerator described above is an example of the present invention, and the present invention is not limited to this. Further, the position of the object detection sensor for opening and closing the revolving door of the beverage supply system is not limited to the position of the present embodiment.

<Configuration of beverage supply system>
Next, the configuration of the beverage supply system 10 according to the present embodiment will be described in detail. In FIG. 5, the internal structure of the drink supply system 10 is shown. 6 and 7 are cross-sectional views taken along line AA of the beverage supply system 10 shown in FIG. 8 and 9 are cross-sectional views taken along line BB of the beverage supply system 10 shown in FIG. 6 and 9 show a case where the rotary door 21 is in a closed state. 7 and 8 show a case where the rotary door 21 is in an open state. Moreover, in FIG. 10, operation | movement of the drink supply system 10 when the user U approaches is shown in order from (a) to (e).

Each part is attached so that the drink supply system 10 may be positioned with respect to the opening formed in the surface of the door 2. That is, the beverage supply system 10 is arranged so as to crawl inside the door 2.

The outer shape of the beverage supply system 10 is formed by a front cover 12 and a back cover 13. As shown in FIG. 8 and the like, a heat insulating material 14 is arranged on the back side of the back cover 13 (side facing the refrigerator compartment). For the heat insulating material 14, conventionally used heat insulating materials such as expanded polystyrene (foamed polystyrene), foamed urethane (urethane spraying), vacuum heat insulating material, and the like can be used. A space having a substantially semicircular cross section is formed between the front cover 12 and the back cover 13. In this space, a water supply chamber (accommodating chamber) 10a is provided. A water injection mechanism 30 (discharge unit) is accommodated inside the water supply chamber 10a in order to discharge the water in the water tank 70 to the glass G of the user U.

Also, as shown in FIG. 8 and the like, a sterilization unit 50 is provided on the back side of the back cover 13. The sterilization unit 50 is installed in a space obtained by hollowing out a part of the heat insulating material 14. In the present embodiment, the sterilization unit 50 is disposed so as to be positioned at a substantially central portion of the water supply chamber 10a when viewed from the front (see FIG. 2). However, the arrangement position of the sterilization unit 50 is not limited to this.

The water supply chamber 10 a includes a bottom portion 15, an upper mounting member 16, a back plate 17, a side plate 19 (right side plate 19 </ b> R, left side plate 19 </ b> L), and a rotating shaft 18 as main components. A space in the water supply chamber 10 a is defined by the bottom portion 15, the upper mounting member 16, the back plate 17, and the side plate 19.

The bottom portion 15 forms the bottom surface of the water supply chamber 10a. The bottom portion 15 functions as a water receiver that receives a beverage such as water spilled from the water inlet 31 or the glass G. A rotating shaft 18 is disposed on the bottom surface of the bottom portion 15. The rotary shaft 18 is rotatably attached to the front cover 12. Thereby, the water supply chamber 10a can rotate centering on the rotation center C (refer FIG. 10).

The upper mounting member 16 is located above the water supply chamber 10a. As shown in FIG. 7 and the like, an upper rotating shaft 61 is provided on the upper portion of the upper mounting member 16. The upper rotating shaft 61 is disposed coaxially with the rotating shaft 18. The upper rotating shaft 61 is connected to a drive motor 62 (see FIG. 5) that drives the rotation of the water supply chamber 10a.

The back plate 17 constitutes the back surface of the water supply chamber 10a. The revolving door 21 is overlapped with the back plate 17. The surface of the revolving door 21 is located in front of the refrigerator 1 when the beverage supply system 10 is not in use (see FIG. 1). Therefore, it is preferable that the surface of the revolving door 21 is formed of the same material as that constituting the surface of the door 2.

The water injection mechanism 30 is disposed above the water supply chamber 10a (that is, the space formed by the upper mounting member 16). The water injection mechanism 30 includes a water injection port 31, a water injection lever 32, a pipe 33, and a support member 34. The water injection lever 32 has an opening 32a. The opening 32 a passes a sterilizing substance (for example, sterilizing ions) released from the sterilization unit 50 described later, and guides it to the water inlet 31.

In the beverage supply system 10 of the present embodiment, when the load is not applied to the water injection lever 32 from the front (the lever is positioned in front), the water injection port 31 is closed. . When a load is applied to the water injection lever 32 from the front (pushing the lever to the back), the valve of the water injection port 31 opens, for example, from the water tank 70 disposed above the water injection mechanism 30 through the pipe 33. Water is poured. The support member 34 is a member that supports the water injection mechanism 30 from the side.

The drinking water can be supplied from the water injection port 31 by using the natural fall due to the weight of the water by disposing the water tank 70 upward. Alternatively, drinking water may be supplied using a pump. When using a pump, it is preferable to reversely rotate the pump at the end of water injection. Thereby, it is possible to prevent water remaining in the pipe 33 from spilling out from the water injection port 31 after the water injection is completed.

With the configuration as described above, the water supply chamber 10a can rotate around an axis composed of the rotary shaft 18 and the upper rotary shaft 61. For example, when the object detection sensor 22 detects that the user's hand is approaching, the drive motor 62 can be driven to rotate the water supply chamber 10a. Thereby, when not in use, the water supply chamber 10a located on the back side of the rotary door 21 appears on the front side of the refrigerator 1 as shown in FIG.

<Configuration of sterilization unit>
In addition, the beverage supply system 10 of the present embodiment is provided with a sterilization unit 50 for suppressing the generation and growth of bacteria, microorganisms and the like in the water supply chamber 10a. The sterilization unit 50 is disposed on the back side of the back cover 13.

The sterilization unit 50 includes an ion generator 51, a fan 52, a gas flow path 53, and the like. The ion generator 51 generates sterilization ions which are a kind of sterilization substance. Here, the sterilizing substance includes chemical substances having an effect of suppressing the generation and growth of bacteria and microorganisms (that is, sterilizing action or antibacterial action), ions having sterilizing action or antibacterial action (plus atoms or molecules). Or those having a negative charge), light having antibacterial action or antibacterial action such as ultraviolet rays, and the like. Examples of the chemical substance having a sterilizing action include hypochlorous acid, ethanol, ozone, and the like. Examples of ions having a sterilizing action include OH radicals, H ⁺ , O ₂ ^{− and the} like.

For example, the ion generator 51 may be an electrostatic atomizer for promoting a sterilization action or an antibacterial action. The electrostatic atomization device electrostatically atomizes a liquid containing a bactericide at a charging unit, and sprays charged fine particles as water droplets. As the electrostatic atomizer, for example, a liquid spray device disclosed in a patent document (Japanese Patent Laid-Open No. 2005-270669) can be used.

Also, instead of the ion generator 51, a spraying apparatus that sprays a liquid containing a chemical substance such as hypochlorous acid or ethanol without ionization can be used.

The fan 52 is disposed inside the gas flow path 53. When the fan 52 starts operation, the gas circulates between the gas flow path 53 and the water supply chamber 10a. In the present embodiment, the fan 52 circulates gas in the direction indicated by the arrow in FIG. That is, gas is blown from the discharge port 53a upward to the water supply chamber 10a. And the gas in the water supply chamber 10a is collect | recovered from the inlet 53b provided below the discharge outlet 53a. In this way, by rotating the fan 52 and circulating the gas between the water supply chamber 10a and the gas flow path 53, it is possible to easily evaporate the water accumulated in the water supply chamber 10a.

The gas flow path 53 is located on the back side of the back cover 13. The gas channel 53 has a discharge port 53a through which the sterilizing substance released from the ion generator 51 flows into the water supply chamber 10a, and an intake port 53b through which the gas in the water supply chamber 10a flows out to the sterilization unit side. And are provided. The discharge port 53 a and the suction port 53 b are formed by providing an opening in the back cover 13. Thereby, when the revolving door 21 is a closed state, the gas flow path 53 and the water supply chamber 10a will be in the communication state.

<Control method of revolving door and sterilization unit>
Next, operations of the rotary door 21 and the sterilization unit 50 will be described. First, the configuration related to the operation of the rotary door 21 and the sterilization unit 50 will be described with reference to FIG.

As shown in FIG. 5, the beverage supply system 10 includes a display panel 23, a human sensor 24, an object detection sensor 22, a drive motor 62, a rotary door 21, a door open / close detection switch 25, an ion generator 51, a fan 52, and a control. The unit 40 and the timer 44 are provided. As described above, the revolving door 21 is attached to the water supply chamber 10a.

The display panel 23 is a touch panel display device and can also function as an operation panel (operation unit). Therefore, the user can change the operation mode of the refrigerator 1 or the operation mode of the beverage supply system 10 from the display panel 23. Information based on the input made by the user to the display panel 23 is transmitted to the control unit 40. Further, the user can open and close the revolving door 21 of the beverage supply system 10 by operating the display panel 23.

The object detection sensor 22 detects that the user's hand or the like using the beverage supply system 10 has approached or the user's hand has touched the sensor. Information detected by the object detection sensor 22 is transmitted to the control unit 40.

The human sensor 24 detects whether or not there is a person around the refrigerator 1. Information detected by the human sensor 24 is transmitted to the control unit 40.

The drive motor 62 is connected to the upper rotary shaft 61 of the water supply chamber 10a to which the rotary door 21 is attached. The drive motor 62 drives the rotation of the water supply chamber 10a.

The door opening / closing detection switch 25 detects whether the revolving door 21 is in an open state or a closed state. The door open / close detection switch 25 is provided, for example, on the rotary door 21 (or the water supply chamber 10a) and the door 2 of the refrigerator compartment. Whether the revolving door 21 is in an open state or a closed state can be detected based on whether or not a switch arranged at each position is in an ON state.

The ion generator 51 and the fan 52 constitute the sterilization unit 50 as described above. The operation of the ion generator 51 and the fan 52 is controlled by the sterilization unit control unit 42 in the control unit 40.

The control unit 40 is connected to each component in the beverage supply system 10 and controls them. In the control unit 40, a rotation control unit 41, a sterilization unit control unit 42, a memory 43, and the like are provided. The control part 40 may be provided independently of the control part of the refrigerator 1 main body, and may be provided in the control part (not shown) of the refrigerator 1 as a part of the structure.

The rotation control unit 41 controls the opening / closing operation of the rotary door 21 of the beverage supply system 10. For example, the rotation control unit 41 starts or stops the operation of the rotary door 21 based on a signal transmitted from the object detection sensor 22. Thereby, the revolving door 21 will be in an open state or a closed state. Here, that the revolving door 21 is in an open state refers to a state in which the water supply chamber 10 a located on the back side of the revolving door 21 is exposed on the front surface of the refrigerator 1. Moreover, that the revolving door 21 is in a closed state means a state in which the revolving door 21 is located on the front side of the refrigerator 1. When the revolving door 21 is in a closed state, the surface of the revolving door 21 and the surface of the door 2 of the refrigerator 1 are substantially flush with each other.

The sterilization unit control unit 42 controls the start and stop of the operation of components (for example, the ion generator 51 and the fan 52) in the sterilization unit 50. Further, the sterilization unit control unit 42 controls the rotation speed of the fan 52.

The memory 43 includes a ROM (read only memory) and a RAM (Random access memory). The memory 43 stores an operation program and setting data of the beverage supply system 10 and temporarily stores a calculation result by the control unit 40. The timer 44 measures the operating time of each unit in the beverage supply system 10 and the time from when one unit stops operating until another unit starts operating. For example, the timer 44 measures the time required for the opening / closing operation of the rotary door 21.

In the beverage supply system 10 of the present embodiment, the opening / closing of the rotary door 21 is controlled based on the detection results of the object detection sensor 22 and the human sensor 24. Furthermore, the start and stop of the operation (operation) of the sterilization unit 50 are controlled depending on whether the rotary door 21 (that is, the water supply chamber 10a) is in an open state or a closed state. Specifically, when the revolving door 21 is in a closed state, the sterilization unit 50 (that is, the ion generator 51 and the fan 52) is in an operating state. In addition, when the rotary door 21 is in the open state, the sterilization unit 50 (that is, the ion generator 51 and the fan 52) is in a stopped state.

Hereinafter, the operation flow of the beverage supply system 10 will be described with reference to FIG. 4 and FIG. In FIG. 10, the water supply chamber 10a of the beverage supply system 10 rotates according to the position of the user's hand (indicated by U in FIG. 10) and the water supply chamber 10a appears on the front (a) to (e). As shown in order.

First, a state when the beverage supply system 10 is not used (a state where water supply is not performed) will be described with reference to FIGS. 6 and 9. When the beverage supply system 10 is not in use, the rotary door 21 is located on the front side of the refrigerator 1. At this time, as shown in FIG. 9, the water supply chamber 10 a has a positional relationship facing the sterilization unit 50. That is, when the beverage supply system 10 is not in use, the space in the water supply chamber 10 a is almost closed by the front cover 12, the back cover 13, and the rotary door 21.

In this state, the door open / close detection switch 25 transmits information that the rotary door 21 is closed to the sterilization unit control unit 42. The sterilization unit control unit 42 keeps the sterilization unit 50 in an operating state while receiving information that the rotary door 21 is closed. That is, a sterilizing substance (for example, + ions and − ions) is generated from the ion generator 51 and the fan 52 is rotated. Thereby, the sterilizing substance is discharged from the discharge port 53a of the gas flow channel 53 toward the water supply chamber 10a (see FIG. 6).

In the present embodiment, the upstream side of the gas flow path 53 (that is, the side on which the fan 52, the ion generator 51, and the discharge port 53a are provided) is inclined upward along the gas flow. . Therefore, the sterilizing substance released from the discharge port 53a to the water supply chamber 10a can be sent toward the upper side of the water supply chamber 10a (that is, the arrangement position of the water injection port 31) as shown by the arrow in FIG. . Thereby, generation | occurrence | production and multiplication of various bacteria around the water inlet 31 can be suppressed.

Furthermore, in this embodiment, the opening part 32a is formed in the water injection lever 32 located between the sterilization unit 50 and the water injection port 31 along the air blowing direction. With this configuration, the disinfecting material discharged from the discharge port 53 a passes through the opening 32 a and is sent around the water injection port 31. Therefore, the sterilizing substance released from the sterilization unit 50 can be sent to the water injection port 31 more efficiently.

Thereafter, as shown in FIGS. 4A and 10A, the user U who wants to drink water holds his hand in front of the object detection sensor 22 while holding the glass G, for example. At this time, information detected by the object detection sensor 22 is transmitted to the rotation control unit 41 and the sterilization unit control unit 42 in the control unit 40.

First, the sterilization unit control unit 42 stops the operation of the sterilization unit 50 (that is, the ion generator 51 and the fan 52).

When the control unit 40 confirms that the sterilization unit 50 has stopped operating, the rotation control unit 41 starts the rotation of the drive motor 62. Then, as shown in FIG. 10B, the beverage supply system 10 starts to rotate counterclockwise around the rotation center C thereof. Thereby, the water supply chamber 10a hidden on the back surface of the rotary door 21 gradually appears on the front side from the left side of the opening of the door 2 of the refrigerator 1 as shown in FIGS. 10 (c) to 10 (d). (Refer FIG.4 (b)). In accordance with the exposure of the water supply chamber 10a, the user U can slide his / her hand to the water supply chamber 10a. And as shown in FIG.4 (c) and FIG.10 (e), when the water injection lever 32 which comprises the water supply chamber 10a is located in the front, rotation operation stops.

The sterilization unit control unit 50 may stop the operation of the sterilization unit 50 after the rotation control unit 41 starts the rotation of the drive motor 62. In this case, as shown in FIGS. 4 (c) and 10 (e), the operation of the sterilization unit 50 is stopped until the water injection lever 32 constituting the water supply chamber 10a is located in the front. preferable. Thereby, after the object detection sensor 22 detects a user's presence, the response time until the operation | movement which the rotation door 21 of the water supply chamber 10a opens starts can be shortened.

As described above, in the beverage supply system 10 according to the present embodiment, the object detection sensor 22 is arranged on the left side of the beverage supply system 10 (see FIG. 1), and the beverage supply system 10 rotates counterclockwise. It has become. That is, the beverage supply system 10 is configured such that the water supply chamber 10a appears from the side where the object detection sensor 22 is disposed. Therefore, the user U holding the glass in his / her hand can place the glass G on the bottom 15 of the water supply chamber 10a by sliding his / her hand rightward from the front of the object detection sensor 22.

At this time, as shown in FIG. 7 and FIG. 8, the water supply chamber 10 a faces the front of the refrigerator 1 and is open. That is, when the rotary door 21 is in the open state, the rotary door 21 is interposed between the water injection mechanism 30 and the sterilization unit 50 (specifically, the discharge port 53a and the suction port 53b of the sterilization unit 50). . Therefore, when the user is performing the water injection operation, the possibility that water may enter the discharge port 53a and the suction port 53b of the sterilization unit 50 is reduced even if water is scattered in the water supply chamber 10a. Can be made.

When the water supply operation is completed, the user leaves the water supply chamber 10a. At this time, the human sensor 24 provided in the display panel 23 detects the presence or absence of a person around the refrigerator 1. When the human sensor 24 detects that a person has left the refrigerator 1 by a predetermined distance or more, this information is transmitted to the rotation control unit 41 in the control unit 40. The rotation control unit 41 receives this information and rotates the rotary door 21 (water supply chamber 10a) in the direction opposite to the above-described rotation operation (that is, clockwise). Thereby, the water supply chamber 10a shifts in order from the state shown in FIG. 10E to the state shown in FIG. 10A, and finally becomes the state shown in FIG.

Thereafter, for example, when the timer 44 measures time and a predetermined time elapses, the sterilization unit control unit 42 starts operation of the sterilization unit 50. Note that the sterilization unit 50 can continue to operate while the rotary door 21 is in the closed state, measure the time by the timer 44, stop the operation after a certain period of time, and then resume the operation. You can also do it.

<Summary of First Embodiment>
As described above, the beverage supply system 10 is mounted on the refrigerator 1 of the present embodiment. The beverage supply system 10 includes a water supply chamber 10a that rotates in the horizontal direction. And the drink supply system 10 has the water supply chamber 10a concealed on the back surface of the revolving door 21 in the non-use state, and in the use state, the revolving door 21 rotates and the water supply chamber 10a is exposed to the front. It has a configuration.

Therefore, according to the configuration of the beverage supply system 10 of the present embodiment, the water supply chamber 10a is not exposed to the outside in a non-use state, so that dust, dirt, and the like are prevented from adhering to the water inlet 31. be able to. Therefore, a more hygienic beverage supply system can be provided.

In addition, when the beverage supply system 10 is not used, the water injection mechanism of the water supply chamber 10a is not exposed to the outside, so that the design of the appearance of the apparatus can be improved. In particular, in the beverage supply system 10 of the present embodiment, the door 2 of the refrigerator 1 and the revolving door 21 of the beverage supply system 10 are located on substantially the same plane, so the aesthetics of the refrigerator 1 when not in use are further improved. be able to.

In addition, the beverage supply system 10 of this embodiment includes a sterilization unit 50. Therefore, propagation of bacteria and microorganisms in the water supply chamber 10a can be suppressed, and a more hygienic beverage supply system can be provided.

Further, in the beverage supply system 10 of the present embodiment, the sterilization unit 50 releases the sterilization substance into the water supply chamber 10a when the rotary door 21 is closed. Thereby, the possibility that the disinfecting substance released into the water supply chamber 10a may be released into the open space can be reduced. Therefore, it becomes easy to maintain the concentration of the sterilizing substance in an appropriate range in the water supply chamber 10a. That is, the concentration of the sterilizing substance in the water supply chamber 10a can be set to a concentration at which a desired sterilizing effect can be obtained. Further, the concentration of the sterilizing substance in the water supply chamber 10a can be maintained at a concentration that does not cause a safety problem.

Some sterilization substances, such as ozone, have a specific odor. When such a disinfecting substance is released into the open space, the possibility of odor spreading increases. On the other hand, according to the beverage supply system 10 of the present embodiment, when the water supply chamber 10a is exposed to the front, the operation of the sterilization unit 50 is stopped, so that the sterilization substance diffuses into the open space. Is suppressed. Therefore, the possibility of odor diffusion can be reduced. For example, when the sterilizing substance contains ozone, the average ozone concentration in the water supply chamber 10a is preferably 0.05 ppm or less, and the maximum ozone concentration in the water supply chamber 10a is 0.1 ppm or less. Is preferred.

Moreover, in the beverage supply system 10 of this embodiment, it is comprised so that the rotation door 21 of the water supply chamber 10a may open from the side by which the object detection sensor 22 is arrange | positioned. Thus, the usability of the beverage supply system 10 can be improved by matching the position of the object detection sensor 22 with the rotation direction of the beverage supply system 10. The position of the object detection sensor and the rotation direction of the beverage supply system described in the present embodiment are examples of the present invention, and the present invention is not limited to this. For example, it is good also as a structure which arrange | positions an object detection sensor on the right side of a drink supply system, and rotates a drink supply system clockwise.

<Second Embodiment>
Subsequently, a second embodiment of the present invention will be described. In 2nd Embodiment, only the structure of the disinfection unit of the drink supply system with which the refrigerator 1 was equipped differs from 1st Embodiment. Therefore, the following description will be focused on a configuration different from the first embodiment.

11 and 12 show the configuration of the beverage supply system 110 according to the second embodiment. 11 and 12 show a cross-sectional configuration of the door 2 shown in FIG. 2 taken along line AA. FIG. 11 shows a case where the revolving door 21 is in a closed state. FIG. 12 shows a case where the revolving door 21 is in an open state.

The outer shape of the beverage supply system 110 is formed by the front cover 12 and the back cover 13. In this space, a water supply chamber (accommodating chamber) 10a is provided. A water injection mechanism 30 (discharge unit) is accommodated inside the water supply chamber 10a in order to discharge the water in the water tank 70 to the glass G of the user U. The water supply chamber 10a includes a bottom portion 15, an upper mounting member 16, a back plate 17, a side plate 19 (right side plate 19R, left side plate 19L), and a rotating shaft 18 as main components. About these, the structure similar to 1st Embodiment is applicable.

Further, a sterilization unit 150 is provided on the back side of the back cover 13. The sterilization unit 150 is installed in a space obtained by hollowing out a part of the heat insulating material 14. Similar to the first embodiment, the sterilization unit 150 is disposed so as to be positioned at a substantially central portion of the water supply chamber 10a when viewed from the front (see FIG. 2).

The sterilization unit 150 includes an ion generator 151, a fan 152, an upper flow path 153, a lower flow path 154, a circulation flow path 155, and the like. The ion generator 151 and the fan 152 can have the same configuration as the ion generator 51 and the fan 52 of the first embodiment.

The upper flow path 153 and the lower flow path 154 are located on the back side of the back cover 13. The upper flow path 153 has a flow path inclined upward from the ion generator 151. In the upper flow path 153, a discharge port 153a through which the sterilizing substance released from the ion generator 151 flows into the water supply chamber 10a is formed. The lower flow path 154 has a flow path inclined downward from the ion generator 151. In the lower flow path 154, a discharge port 154a through which the sterilizing substance released from the ion generator 151 flows into the water supply chamber 10a is formed. The circulation channel 155 is arranged on the upstream side of the ion generator 51. The circulation channel 155 is formed with an inlet 155b through which the gas in the water supply chamber 10a flows out to the sterilization unit side. The discharge port 153a, the discharge port 154a, and the suction port 155b are formed by providing an opening in the back cover 13.

With this configuration, when the rotary door 21 is closed, the upper flow path 153, the lower flow path 154, the circulation flow path 155, and the water supply chamber 10a are in communication with each other. Further, the upper flow path 153 discharges the sterilizing substance from the ion generator 151 obliquely upward (see the arrow in FIG. 11). Moreover, the downward flow path 154 discharge | releases the substance for disinfection from the ion generator 151 diagonally downward (refer the arrow of FIG. 11). Moreover, the gas in the water supply chamber 10a is collect | recovered from the inlet 155b provided under the water supply chamber 10a. Then, by rotating the fan 152 and circulating the gas between the water supply chamber 10a and each of the

flow paths

153, 154, and 155, it is possible to easily evaporate the water accumulated in the water supply chamber 10a.

In the first embodiment, the suction port 53b is disposed immediately below the discharge port 53a so as to be adjacent to the discharge port 53a. On the other hand, in 2nd Embodiment, the inlet 155b is arrange | positioned more downward (for example, the height substantially the same as the bottom part 15 of the water supply chamber 10a). With this configuration, the gas circulating between the water supply chamber 10a and each of the

flow paths

153, 154, and 155 can be distributed more under the water supply chamber 10a.

Similarly to the first embodiment, in the beverage supply system 110, the sterilization unit 150 operates when the rotary door 21 is closed to release the sterilizing substance into the water supply chamber 10a (FIG. 11), the operation is stopped when the revolving door 21 is open (see FIG. 12). Thereby, the possibility that the disinfecting substance released into the water supply chamber 10a may be released into the open space outside the water supply chamber 10a can be reduced. Therefore, it becomes easy to maintain the concentration of the sterilizing substance in an appropriate range in the water supply chamber 10a.

As described above, in the beverage supply system 110 of the present embodiment, the sterilization unit 50 is provided with the two

discharge ports

153a and 154a. Thereby, the sterilizing substance can be released toward a wider area of the water supply chamber 10a. More specifically, the sterilizing substance released from the discharge port 153 a can be discharged toward the water injection port 31. In addition, the sterilizing substance released from the discharge port 154a can be released toward the lower side of the water supply chamber 10a.

In addition to the above, for example, a plurality of ion generators may be installed in different places, and the sterilizing substance may be discharged to different places in the water supply chamber 10a. Moreover, the air blowing direction of the fan can be changed, and the sterilizing substance may be discharged in multiple directions of the water supply chamber 10a. At this time, it is preferable to release the disinfecting substances toward the water inlet 31 of the water injection mechanism 30 and the bottom 15 where water can easily accumulate.

<Third Embodiment>
Subsequently, a third embodiment of the present invention will be described. In 3rd Embodiment, only the structure of the disinfection unit of the drink supply system with which the refrigerator 1 was equipped differs from 1st Embodiment. Therefore, the following description will be focused on a configuration different from the first embodiment.

13 and 14 show a configuration of a beverage supply system 210 according to the third embodiment. 13 and 14 show a cross-sectional configuration of the door 2 shown in FIG. 2 taken along line AA. FIG. 13 shows a case where the revolving door 21 is in a closed state. FIG. 14 shows a case where the revolving door 21 is in an open state.

The outer shape of the beverage supply system 210 is formed by the front cover 12 and the back cover 13. In this space, a water supply chamber (accommodating chamber) 10a is provided. A water injection mechanism 30 (discharge unit) is accommodated inside the water supply chamber 10a in order to discharge the water in the water tank 70 to the glass G of the user U. The water supply chamber 10a includes a bottom portion 15, an upper mounting member 16, a back plate 17, a side plate 19 (right side plate 19R, left side plate 19L), and a rotating shaft 18 as main components. About these, the structure similar to 1st Embodiment is applicable.

Further, a sterilization unit 250 is provided on the back side of the back cover 13. The sterilization unit 250 is installed in a space obtained by hollowing out a part of the heat insulating material 14.

The sterilization unit 250 includes an ion generator 251, a fan 252, a gas flow path 253, and the like. The ion generator 251 and the fan 252 can have the same configuration as the ion generator 51 and the fan 52 of the first embodiment.

The gas flow path 253 is located on the back side of the back cover 13. The gas channel 253 has a discharge port 253a through which the sterilizing substance released from the ion generator 251 flows into the water supply chamber 10a, and a suction port 253b through which the gas in the water supply chamber 10a flows out to the sterilization unit side. And are provided. The discharge port 253 a and the suction port 253 b are formed by providing an opening in the back cover 13. Thereby, when the revolving door 21 is a closed state, it will be in the state which the gas flow path 253 and the water supply chamber 10a connected.

In the first embodiment, the suction port 53b is disposed immediately below the discharge port 53a so as to be adjacent to the discharge port 53a. On the other hand, in 3rd Embodiment, the inlet 253b is arrange | positioned more downward (for example, the height substantially the same as the bottom part 15 of the water supply chamber 10a). With this configuration, the gas circulating between the water supply chamber 10a and the gas flow path 253 can be distributed more under the water supply chamber 10a.

Similarly to the first embodiment, in the beverage supply system 210, the sterilization unit 250 operates when the rotary door 21 is closed to release the sterilizing substance into the water supply chamber 10a (FIG. 13), the operation is stopped when the revolving door 21 is open (see FIG. 14). Thereby, the possibility that the disinfecting substance released into the water supply chamber 10a may be released into the open space outside the water supply chamber 10a can be reduced. Therefore, it becomes easy to maintain the concentration of the sterilizing substance in an appropriate range in the water supply chamber 10a.

<Fourth Embodiment>
Subsequently, a fourth embodiment of the present invention will be described. In 4th Embodiment, only the structure of the disinfection unit of the drink supply system with which the refrigerator 1 was equipped differs from 1st Embodiment. Therefore, the following description will be focused on a configuration different from the first embodiment.

15 and 16 show the configuration of the beverage supply system 310 according to the fourth embodiment. 15 and 16 show a cross-sectional configuration of the door 2 shown in FIG. 2 taken along line AA. FIG. 15 shows a case where the revolving door 21 is in a closed state. FIG. 16 shows a case where the revolving door 21 is in an open state.

The outer shape of the beverage supply system 310 is formed by the front cover 12 and the back cover 13. In this space, a water supply chamber (accommodating chamber) 10a is provided. A water injection mechanism 30 (discharge unit) is accommodated inside the water supply chamber 10a in order to discharge the water in the water tank 70 to the glass G of the user U. The water supply chamber 10a includes a bottom portion 15, an upper mounting member 16, a back plate 17, a side plate 19 (right side plate 19R, left side plate 19L), and a rotating shaft 18 as main components. About these, the structure substantially the same as 1st Embodiment is applicable. However, the point that the opening part is not formed in the water injection lever 332 of the water injection mechanism 30 is different from the first embodiment.

In this embodiment, the disposition position of the sterilization unit 350 is different from that of the first embodiment. As shown in FIG. 15, the sterilization unit 350 is installed above the back side of the revolving door 21 (that is, the back plate 17 side). The sterilization unit 350 is not an ion generator but a UV irradiator. Therefore, ultraviolet rays are radiated from the sterilization unit 350 as a sterilization substance. Since the ultraviolet rays have a bactericidal effect, the ultraviolet rays irradiated from the sterilization unit 350 hit the water injection port 31 and the like, so that the growth of germs and molds existing around the water injection port 31 can be suppressed. The wavelength of the irradiated ultraviolet light is, for example, 400 nm or less. Preferably, ultraviolet rays having a wavelength region of 250 nm to 300 nm are used.

Further, in the beverage supply system 310, the sterilization unit 350 operates when the revolving door 21 is closed to irradiate ultraviolet rays (see FIG. 15), and operates when the revolving door 21 is open (ultraviolet light). (Irradiation) is stopped (see FIG. 16). Thereby, when the water supply chamber 10a is exposed to the front, the irradiation of ultraviolet rays that can be harmful to the human body can be stopped.

In the case of the sterilization unit 350 configured as described above, the rotary door 21 of the beverage supply system 310 can be configured as a shutter-type opening / closing door that slides in the vertical direction or the horizontal direction.

<Modification of Third Embodiment>
Below, the modification of 3rd Embodiment is demonstrated. In FIG. 17, the structure of drink supply system 310 'concerning a modification is shown. In the beverage supply system 310 ′, the sterilization method is different from that in the third embodiment. Specifically, the beverage supply system 310 ′ performs sterilization using a photocatalyst and light.

As shown in FIG. 17, in the beverage supply system 310 ′, a photocatalytic layer 355 ′ is formed around the water inlet 31 at the tip portion of the water injection mechanism 30. The photocatalyst layer 355 'contains, for example, titanium oxide as a photocatalyst. In addition, the beverage supply system 310 ′ includes a light irradiator as the sterilization unit 350 ′. Ultraviolet light or visible light is emitted from the light irradiator. When the light emitted from the light irradiator strikes the photocatalyst layer 355 ', OH radicals are generated from the photocatalyst layer 355'. Since the OH radical has a strong oxidizing power, it can kill bacteria and microorganisms present on the surface.

As in the third embodiment, in the beverage supply system 310 ′, the sterilization unit 350 ′ operates to irradiate light when the revolving door 21 is closed (see FIG. 17), and the revolving door. The operation (light irradiation) is stopped when 21 is open.

<Fifth Embodiment>
Subsequently, a fifth embodiment of the present invention will be described. In each embodiment mentioned above, the example in which the drink supply system was built in the refrigerator was explained. However, the beverage supply system of one embodiment of the present invention does not necessarily have to be built in the refrigerator, and may be installed alone, for example, in a facility such as a gymnasium, a sports facility, or a hospital. Therefore, in this embodiment, an example in which a beverage supply system is installed alone will be described.

FIG. 18A shows an external configuration of the beverage supply system 400 according to the present embodiment. FIG. 18A shows a state when the beverage supply system 400 is in use. Moreover, in FIG.18 (b), the internal structure of the drink supply system 400 is shown.

The beverage supply system 400 includes a surface panel 401, a water supply chamber 10a, a water tank 70, an object detection sensor 422, a display panel 423, and the like. The structure similar to 1st Embodiment is applicable to the water supply chamber 10a.

In addition, the beverage supply system 400 includes a sterilization unit 50. When the revolving door 21 is in the open state, the sterilization unit 50 exists on the back plate 17 and the back side of the revolving door 21. That is, when the rotary door 21 is in the open state, the rotary door 21 and the back plate 17 are interposed between the water inlet 31 and the sterilization unit 50. Therefore, when the revolving door 21 is in the open state, the sterilization unit 50 is in a state invisible from the front. In FIG. 18, for the sake of convenience, the sterilization unit 50 is indicated by a broken line.

As shown in FIG. 18B, the revolving door 421 is provided as a part of the structure of the water supply chamber 10a. Specifically, the rotary door 421 is disposed so as to overlap the back plate 17.

The beverage supply system 400 is configured such that the rotating door 421 rotates in the horizontal direction when the object detection sensor 422 detects a user's hand or the like. When the revolving door 421 rotates, the water supply chamber 10a appears in the front. About the control method of the opening / closing operation | movement of the revolving door 421, the structure similar to the drink supply system 10 of 1st Embodiment is applicable.

Further, as in the first embodiment, in the beverage supply system 400, the sterilization unit 50 operates when the rotary door 421 is in the closed state to release the sterilizing substance into the water supply chamber 10a and rotates. The operation is stopped when the door 21 is open. Thereby, the possibility that the disinfecting substance released into the water supply chamber 10a may be released into the open space can be reduced. Therefore, it becomes easy to maintain the concentration of the sterilizing substance in an appropriate range in the water supply chamber 10a.

<Sixth Embodiment>
The rotating structure of the water supply chamber in the beverage supply system described above is not limited to the beverage supply system, but a small revolving door is provided on a part of the main door of the refrigerator, and a small storage (retaining system with a door) is provided on the back of the revolving door. It is also applicable to the structure of a refrigerator provided with. In such a small storage, for example, one or several drinks (milk pack, drink pack, PET bottle tea or soft drink, etc.) can be stored.

If a beverage with higher usage frequency is stored in such a small storage, the desired beverage can be taken out from the rotary door without opening the main door of the refrigerator. Thus, by taking out a drink from a rotation door, the temperature rise in a refrigerator can be suppressed compared with the case where a main door is opened and a drink is taken out. Further, by providing the revolving door of the small storage box at a relatively low position, even a small child can easily take out the beverage from the revolving door.

In the sixth embodiment, an example in which the configuration of the storage system with a door according to one aspect of the present invention is applied to a small storage mounted on a refrigerator will be described. FIG. 19A to FIG. 19C show a refrigerator 500 according to the sixth embodiment.

As shown in FIG. 19 (a), the refrigerator 500 includes a small storage box 510, a display panel 523, and the like on the door 502 of the refrigerator compartment. The small storage 510 includes a rotary door 521, an object detection sensor 522, and the like. The object detection sensor 522 is disposed on the right side of the small storage 510.

Further, as shown in FIG. 19B, a storage chamber (storage chamber) 510a is provided on the back side of the rotary door 521. In the storage room 510a, for example, one or several beverages (milk pack, beverage pack, can beverage, PET bottle tea or soft drink, etc.) can be stored.

The small storage 510 is configured such that the revolving door 521 rotates in the horizontal direction when the object detection sensor 522 detects a user's hand or the like. When the revolving door 521 rotates, the storage chamber 510a appears on the front as shown in FIG. In the present embodiment, the object detection sensor 522 is disposed on the right side of the rotary door 521. Therefore, when the object detection sensor 522 detects a user's hand or the like, the rotary door 521 rotates in the opposite direction (that is, clockwise) from the rotary door 21 of the first embodiment. As in the first embodiment, when the object detection sensor 522 is arranged on the left side of the revolving door 521, the revolving door 521 is preferably rotated counterclockwise to be in an open state.

If a beverage with higher usage frequency is stored in such a small storage 510, the desired beverage can be taken out from the rotary door 521 without opening the door 502 of the refrigerator 500. Thus, by taking out the beverage from the rotary door 521, it is possible to suppress an increase in the temperature in the refrigerator as compared with the case of opening the door 502 and taking out the beverage. Further, by providing the revolving door 521 of the small storage 510 at a relatively low position, even a small child can easily take out the beverage from the revolving door 521.

Also, the small storage 510 according to the present embodiment is provided with a sterilization unit 50 as in the first embodiment. When the revolving door 521 is in the open state, the sterilization unit 50 exists on the back plate and the back side of the revolving door 521. Therefore, when the revolving door 521 is in the open state, the sterilization unit 50 is in a state invisible from the front. In FIG. 19C, the sterilization unit 50 is indicated by a broken line for convenience.

Similarly to the first embodiment, in the small storage 510, the sterilization unit 50 operates when the rotary door 521 is in a closed state to release the sterilizing substance into the storage chamber 510a, and rotates. The operation is stopped when the door 521 is open. Thereby, the possibility that the disinfecting substance released into the storage chamber 510a may be released into the open space can be reduced. Therefore, it becomes easy to maintain the concentration of the sterilizing substance in an appropriate range in the storage chamber 510a.
