Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same components 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 >

< overview of refrigerator >

In the present embodiment, a configuration in which a door-equipped storage system according to an aspect of the present invention is applied to a beverage supply system will be described as an example of the present invention. In the present embodiment, an example of a configuration in which the beverage supply system is incorporated in a refrigerator will be described. However, the beverage supply system according to the aspect of the present invention may not necessarily be built in the refrigerator. First, an outline of the refrigerator 1 in which the beverage supply system 10 according to the present embodiment is installed will be described. Fig. 1 is a front view showing a refrigerator 1 to which a beverage supply system 10 according to the present embodiment is attached.

In the refrigerator 1 according to the present embodiment, the refrigerating chamber is attached to the upper portion, and the freezing chamber is attached to the lower portion. As shown in fig. 1, the refrigerator 1 has 4 doors. Specifically, the refrigerating chamber in the upper part is provided with a double door type door (right door) 2 and a door (left door) 3. Also, a double door type door is provided in the lower freezing chamber. Further, a handle 4 is provided on each door of the refrigerator. The beverage supply system 10 is mounted on the right side door 2 when viewed from the front of the refrigerator 1 for the refrigerating chamber.

However, the refrigerator 1 in which the beverage supply system 10 is installed may have a structure having less than 4 doors, or may have a structure having more than 4 doors, and the refrigerating chamber may be disposed at a lower layer or a middle layer.

Fig. 1 shows a state of the beverage supply system 10 when not in use. As shown in fig. 1, in a state of non-use, the revolving door 21 of the beverage supply system 10 is positioned on the front side of the refrigerator 1. That is, the water injection mechanism of the beverage supply system 10 is disposed on the back side of the revolving door 21 (door) and is invisible. An object detection sensor 22 is provided in the vicinity of the revolving 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 left door 3 of the refrigerating compartment. The display panel 23 is a touch panel type display device, and can function as an operation panel (operation unit). Therefore, the user can change the operation mode of the refrigerator 1, the operation mode of the beverage supply system 10, and the like through the operation panel.

The object detection sensor 22 detects the proximity of a user's hand or the like around the user who uses the beverage supply system 10, or the sensor is touched by the user's hand. Further, the object detection sensor 22 is constituted by, for example, a non-contact sensor of a capacitive type. 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. ). This can prevent the hands or the glass from adhering to the surface of the door 2 of the refrigerator 1. However, the present invention is not limited to this, and the detection unit for detecting whether or not an object is present in the vicinity of the revolving door may be configured by a touch sensor, a key, or the like.

Further, a human body sensor 24 is provided in the display panel 23. The human body sensor 24 detects whether a human body exists around the refrigerator 1. The human body sensor 24 is constituted by a noncontact sensor such as a photoelectric sensor.

The detection results of the object detection sensor 22 and the human body induction sensor 24 are sent to a control unit 40 (see fig. 5) provided in the beverage supply system 10. The control unit 40 controls the opening/closing of the revolving door 21 based on the detection results of the respective sensors. For example, when the object detection sensor 22 detects that the user's hand has approached or touched, the control section 40 switches the swing door 21 from the closed state to the open state. For example, the motion sensor 24 can maintain the revolving door 21 in the open state regardless of whether or not the beverage supply system 10 is in use while detecting the presence of a person.

Fig. 2 is a front view of a right-side door 2 portion for a refrigerating compartment. Fig. 3 is a perspective view of a right door 2 portion for a refrigerating compartment. Fig. 2 and 3 show a state in which the beverage supply system 10 is used. The water tank 70 of the beverage supply system 10 is disposed on the rear side of the door 2, and is not visible from the front, but the water tank 70 is shown by a broken line in fig. 2 for convenience.

The beverage supply system 10 is configured such that when the object detection sensor 22 detects a hand of a user or the like, the rotary door 21 is rotated in the horizontal direction, and the water injection mechanism appears on the front (see fig. 4). As shown in fig. 2 and 3, when the rotary door 21 is rotated, the bottom 15 (water receiving), the back panel 17, the side panel 19, the water filling handle (handle) 32, and the like constituting the beverage supply system 10 appear on the front.

Then, the water in the water tank 70 cooled in the refrigerating chamber is discharged from the water filling port 31 (the discharge port of the discharge portion) based on the operation of the user. In the present embodiment, for example, the user presses the water filling handle 32 toward the back panel 17 using a container (water receiving member) such as a glass to supply water into the glass. In the present embodiment, an opening 32a is formed in a substantially central portion of the water filling handle 32.

The beverage supply system 10 of the present embodiment is provided with a sterilizing unit 50. When the rotary door 21 is in the open state, the sterilizing unit 50 is present on the back panel 17 and the back side of the rotary door 21 (see fig. 7). That is, when the rotary door 21 is in the open state, the rotary door 21 and the back panel 17 are interposed between the water filling port 31 and the sterilizing unit 50. Therefore, when the swing door 21 is in the open state, although the sterilizing unit 50 is in a state of being invisible from the front, in fig. 2, the sterilizing unit 50 is indicated by a broken line for convenience. A more detailed configuration of the beverage supply system 10 including the sterilizing unit 50 and the like will be described later.

Although the installation location of the object detection sensor 22 is not particularly limited, it is disposed on the left side of the beverage supply system 10 in the present embodiment. Also, as shown in fig. 4(a) to (c), if the object detection sensor 22 detects a user, the rotary door 21 of the beverage supply system 10 rotates counterclockwise, and the water injection mechanism appears from the left side. Thus, a user holding the glass G or the like in his hand can easily bring his hand close to the water filling mechanism by moving his hand laterally from the vicinity of the front surface of the object detection sensor 22.

According to the above configuration, the convenience of the beverage supply system is further improved. Further, in the case of a configuration in which the revolving door of the beverage supply system is rotated clockwise, it is preferable to provide an object detection sensor at the right side of the beverage supply system. In this way, the object detection sensor is preferably arranged in connection with the direction of rotation of the beverage supply system.

The configuration 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 thereto. 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.

< construction of beverage supply System >

Next, the configuration of the beverage supply system 10 according to the present embodiment will be described in detail. Fig. 5 shows an internal configuration of the beverage supply system 10. Fig. 6 and 7 are sectional views taken along line a-a of the beverage supply system 10 shown in fig. 2. Fig. 8 and 9 are sectional views taken along line B-B of the beverage supply system 10 shown in fig. 2. Fig. 6 and 9 show a state in which the revolving door 21 is closed. Fig. 7 and 8 show a state in which the swing door 21 is opened. In fig. 10, the operation of the beverage supply system 10 when the user U approaches is shown in the order of (a) to (e).

The beverage supply system 10 mounts each component so that a position thereof is determined with respect to an opening formed in a surface of the door 2. That is, the beverage supply system 10 is disposed so as to dig inside the door 2.

The beverage supply system 10 is formed in its outer shape with a front cover 12 and a back cover 13. As shown in fig. 8 and the like, a heat insulating material 14 is disposed on the back side (the side facing the refrigerating compartment) of the back cover 13. The heat insulating material 14 may use a conventionally used heat insulating material, for example, styrofoam (polystyrene foam), polyurethane foam (spray polyurethane), a vacuum heat insulating material, or the like. Between the front cover 12 and the rear cover 13, a substantially semicircular space is formed in cross section. A water supply chamber (housing chamber) 10a is provided in the space. A water filling mechanism 30 (discharge unit) for discharging water in the water tank 70 to the glass G of the user U or the like is housed in the water supply chamber 10 a.

As shown in fig. 8 and the like, a sterilization unit 50 is provided on the back surface side of the back cover 13. The sterilizing unit 50 is provided in a space obtained by hollowing out a part of the heat insulating material 14. In the present embodiment, the bacteria removing unit 50 is disposed at a substantially central portion of the water supply chamber 10a in front view (see fig. 2). However, the arrangement position of the sterilizing unit 50 is not limited thereto.

The water supply chamber 10a includes, as main components, a bottom 15, an upper mounting member 16, a back plate 17, side plates 19(a right side plate 19R and a left side plate 19L), and a rotary shaft 18. The bottom 15, the upper mounting member 16, the back plate 17, and the side plate 19 define a space in the water supply chamber 10 a.

The bottom 15 forms a bottom surface of the water supply chamber 10 a. The bottom portion 15 functions as a water receiver for receiving a drink such as water overflowing from the water filling port 31 and the glass G. A rotary shaft 18 is disposed below the bottom portion 15. The rotary shaft 18 is rotatably attached to the front cover 12. Thereby, the water supply chamber 10a can be rotated about the rotation center C (refer to fig. 10).

The upper mounting member 16 is positioned above the water supply chamber 10 a. As shown in fig. 7 and the like, an upper rotary shaft 61 is provided above the upper mounting member 16. The upper rotary shaft 61 is provided coaxially with the rotary shaft 18. Further, the upper rotary shaft 61 is connected to a drive motor 62 (refer to fig. 5) that drives the rotation of the water supply chamber 10 a.

The back plate 17 constitutes the back surface of the water supply chamber 10 a. The swing door 21 overlaps the back panel 17. When the beverage supply system 10 is not in use, the surface of the rotary door 21 is located on the front surface of the refrigerator 1 (refer to fig. 1). For this reason, the surface of the rotary door 21 is preferably 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 (i.e., in the space formed by the upper mounting member 16). The water injection mechanism 30 includes a water injection port 31, a water injection handle 32, a conduit 33, and a support member 34. An opening 32a is formed in the water filling handle 32. The opening 32a guides a substance for sterilization (for example, sterilization ions) released from the sterilization unit 50 described later to the water inlet 31.

In the beverage supply system 10 of the present embodiment, when no load is applied to the water filling handle 32 from the front (the handle is in front of the hand), the water filling port 31 is in the closed state. Then, if a load is applied to the water filling handle 32 from the front (if the handle is pressed backward), the valve of the water filling port 31 is opened, and water is filled from the water tank 70 disposed above the water filling mechanism 30 through the conduit 33, for example. The support member 34 supports the water injection mechanism 30 from the side.

The drinking water can be supplied from the water filling port 31 by disposing the water tank 70 at the upper side and using free fall according to the weight of the water. Alternatively, the supply of drinking water may be performed using a pump. In the case of a pump, the pump is preferably rotated in reverse at the end of the water injection. This can prevent the water remaining in the conduit 33 from overflowing the water filling port 31 after the water filling operation is completed.

With the above configuration, water supply chamber 10a can rotate about the axis formed by rotation shaft 18 and upper rotation shaft 61. Also, for example, if the object detection sensor 22 detects that the user's hand has approached, the drive motor 62 can be driven and the water supply chamber 10a is rotated. Thus, when not in use, the water supply chamber 10a located on the back side of the rotary door 21 appears to the front side of the refrigerator 1 shown in fig. 2.

< construction of Sterilization Unit >

Further, the beverage supply system 10 of the present embodiment includes a sterilizing unit 50 for suppressing the generation and propagation of bacteria, microorganisms, and the like in the water supply chamber 10 a. The sterilization unit 50 is disposed on the back side of the back cover 13.

The sterilization unit 50 is constituted by an ionizer 51, a fan 52, a gas flow path 53, and the like. The ionizer 51 is caused to generate sterilizing ions which are one of the substances for sterilization. The sterilization substance includes a chemical substance having an effect of inhibiting the generation and propagation of bacteria and microorganisms (i.e., a sterilization effect and an antibacterial effect), an ion (a substance having a positively or negatively charged atom or molecule) having a sterilization effect or an antibacterial effect, light having a sterilization effect or an antibacterial effect such as ultraviolet light, and the like. Examples of the chemical substance having a sterilizing effect include hypochlorous acid, ethanol, ozone, and the like. Further, as the ion having a sterilizing action, for example, OH radical, H⁺、O₂ ^-And the like.

For example, the ionizer 51 may be an electrostatic atomizing device for promoting sterilization or antibacterial action. The electrostatic atomization device electrostatically atomizes a liquid containing a bactericide by a charging section, and sprays charged fine particles as water droplets. As the electrostatic atomization device, for example, a liquid spray device disclosed in patent document (japanese patent laid-open No. 2005-270669) or the like can be used.

Further, instead of the ionizer 51, a spray device that does not perform ionization spraying of a liquid containing a chemical substance such as hypochlorous acid or ethanol may be used.

The fan 52 is disposed inside the gas flow passage 53. If the fan 52 starts to operate, the gas circulates between the gas flow passage 53 and the water supply chamber 10 a. In the present embodiment, the fan 52 circulates the gas in the direction indicated by the arrow in fig. 6. That is, the gas is blown from the discharge port 53a to the upper side of the water supply chamber 10 a. Then, the gas in the water supply chamber 10a from the suction port 53b provided below the discharge port 53a is collected. By rotating the fan 52 in this manner, the moisture remaining in the water supply chamber 10a can be easily evaporated by circulating the gas between the water supply chamber 10a and the gas flow path 53.

The gas flow passage 53 is located on the inner side of the back cover 13. The gas flow path 53 is provided with a discharge port 53a through which the bacteria removing substances discharged from the ionizer 51 flow into the water supply chamber 10a, and a suction port 53b through which the gas in the water supply chamber 10a flows out to the bacteria removing unit side. The discharge port 53a and the suction port 53b are formed by providing an opening in the rear cover 13. Thus, when the rotary door 21 is in the closed state, the gas flow passage 53 and the water supply chamber 10a are in a state of communication.

< method for controlling revolving door and sterilizing unit >

The operation of the rotary door 21 and the sterilizing unit 50 will be described. First, referring to fig. 5, the structure of the operation of the rotary door 21 and the sterilizing unit 50 will be described.

As shown in fig. 5, the beverage supply system 10 includes a display panel 23, a human body sensor 24, an object detection sensor 22, a drive motor 62, a rotary door 21, a door open/close detection switch 25, an ionizer 51, a fan 52, a control unit 40, a clock 44, and the like. As described above, the rotary door 21 is attached to the water supply chamber 10 a.

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

The object detection sensor 22 detects the approach of a hand or the like of a user using the beverage supply system 10 to the surroundings thereof, or the contact of the hand of the user with the sensor. The information detected by the object detection sensor 22 is transmitted to the control unit 40.

The human body induction sensor 24 detects whether or not a human body exists around the refrigerator 1. The information detected by the motion sensor 24 is transmitted to the control unit 40.

The driving 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 driving motor 62 drives the rotation of the water supply chamber 10 a.

The door open/close detection switch 25 detects whether the revolving door 21 is in the open state or the closed state. The door open/close detection switches 25 are provided, for example, in the rotary door 21 (or the water supply chamber 10a) and the door 2 of the refrigerating chamber, respectively. Whether the revolving door 21 is in the open state or the closed state can be detected based ON whether or not the switches disposed at the respective positions are in the ON state.

As described above, the ionizer 51 and the fan 52 constitute the sterilizing unit 50. The operation of the ionizer 51 and the fan 52 is controlled by the sterilizing unit control unit 42 in the control unit 40.

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

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 swing door 21 based on a signal transmitted from the object detection sensor 22. Thereby, the swing door 21 is in an open state or in a closed state. Here, the state where the swing door 21 is opened means a state where the water supply chamber 10a located on the rear surface side of the swing door 21 is exposed on the front surface of the refrigerator 1. The state where the swing door 21 is closed is a state where the swing door 21 is positioned on the front surface side of the refrigerator 1. When the swing door 21 is in the closed state, the surface of the swing door 21 and the surface of the door 2 of the refrigerator 1 are substantially flush with each other.

The degerming unit control section 42 controls the start and stop of the operation of the constituent components (e.g., the ionizer 51, the fan 52, etc.) in the degerming unit 50. The bacteria removing unit control unit 42 controls the number of rotations of the fan 52.

The storage unit 43 includes a rom (read only memory) and a ram (random Access memory). The storage unit 43 temporarily stores the calculation results by the control unit 40 while storing the operation program and setting data of the beverage supply system 10. The clock 44 measures the operation time of each unit in the beverage supply system 10 and the time from when a certain unit stops operating to when another unit starts operating. For example, the clock 44 measures a desired time of the opening/closing action 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 body induction sensor 24. Further, the start and stop of the operation (action) of the sterilizing unit 50 are controlled according to whether the rotary door 21 (i.e., the water supply chamber 10a) is in the open state or the closed state. Specifically, when the rotary door 21 is in the closed state, the sterilizing unit 50 (i.e., the ionizer 51 and the fan 52) is in the operating state. When the rotary door 21 is opened, the sterilizing unit 50 (i.e., the ionizer 51 and the fan 52) is stopped.

The operation flow of the beverage supply system 10 will be described below with reference to fig. 4 and 10. In fig. 10, water supply chamber 10a of beverage supply system 10 is rotated according to the position of the user's hand (indicated by U in fig. 10), and the appearance of water supply chamber 10a is shown in the order of (a) to (e).

First, a state in which the beverage supply system 10 is not in use (a state in which water supply is not performed) will be described with reference to fig. 6 and 9. In a state where the beverage supply system 10 is not in use, the rotary door 21 is positioned on the front side of the refrigerator 1. At this time, as shown in fig. 9, the water supply chamber 10a is in a positional relationship facing the sterilizing unit 50. That is, when the beverage supply system 10 is not in use, the space in the water supply chamber 10a is substantially closed by the front cover 12, the rear 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 in the closed state to the bacteria elimination unit control unit 42. In the sterilizing unit control portion 42, the sterilizing unit 50 enters the operating state while receiving the information that the swing door 21 is in the closed state. That is, the fan 52 is rotated while the substance for sterilization (for example, + ions and-ions) is generated from the ionizer 51. Thereby, the substance for sterilization is discharged from the discharge port 53a of the gas flow passage 53 to the water supply chamber 10a (see fig. 6).

In the present embodiment, the upstream side of the gas flow path 53 (i.e., the side where the fan 52, the ionizer 51, and the discharge port 53a are provided) is inclined upward along the gas flow. Therefore, as shown by the arrow in fig. 6, the substance for sterilization released from the discharge port 53a into the water supply chamber 10a can be sent toward the upper side of the water supply chamber 10a (i.e., the position where the water filling port 31 is disposed). This can suppress the generation and propagation of bacteria around the water injection port 31.

Further, in the present embodiment, the opening 32a is formed in the water filling handle 32 located between the sterilizing unit 50 and the water filling port 31 in the air blowing direction of the gas. With this configuration, the substance for sterilization released from the discharge port 53a is sent to the periphery of the water filling port 31 through the opening 32 a. Therefore, the substance for sterilization released from the sterilization unit 50 can be more efficiently sent to the water inlet 31.

Thereafter, as shown in fig. 4(a) and 10(a), the user U who wants to drink water stretches his or her grip on the front surface of the object detection sensor 22, for example, in a state of holding the glass G or the like. At this time, the information detected by the object detection sensor 22 is transmitted to the rotation control unit 41 and the bacteria elimination unit control unit 42 in the control unit 40.

Then, first, the degerming unit control section 42 stops the operation of the degerming unit 50 (i.e., the ionizer 51 and the fan 52).

Then, in the control section 40, if it is confirmed that the sterilizing unit 50 has stopped operating, the rotation control section 41 starts the rotation of the drive motor 62. Then, as shown in fig. 10(b), the beverage supply system 10 starts counterclockwise rotation around the rotation center C. As a result, the water supply chamber 10a hidden inside the rotary door 21 gradually appears from the left side of the opening of the door 2 of the refrigerator 1 to the front side as shown in fig. 10 c to 10 d (see fig. 4 b). In conjunction with the exposure of the water supply chamber 10a, the user U can slide his hand toward the water supply chamber 10 a. As shown in fig. 4(c) and 10(e), when the water filling lever 32 constituting the water supply chamber 10a is positioned on the front surface, the rotation operation is stopped.

Further, the sterilizing unit control portion 50 may stop the operation of the sterilizing unit 50 after the rotation control portion 41 starts the rotation of the driving motor 62. In this case, as shown in fig. 4(c) and 10(e), it is preferable to stop the operation of the sterilizing unit 50 until the water filling handle 32 constituting the water supply chamber 10a is positioned at the front. This can shorten the response time until the start of the operation of opening the rotary door 21 of the water supply chamber 10a after the presence of the user is detected by the object detection sensor 22.

As described above, in the beverage supply system 10 of the present embodiment, the object detection sensor 22 (see fig. 1) is disposed on the left side of the beverage supply system 10, and the beverage supply system 10 is configured to rotate counterclockwise. 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 arranged. Therefore, the user U who holds the glass by hand can place the glass G on the bottom 15 of the water supply chamber 10a by sliding the hand from the front of the object detection sensor 22 in the right direction with the hand kept constant.

At this time, as shown in fig. 7 and 8, the water supply chamber 10a is opened toward the front of the refrigerator 1. That is, when the rotary door 21 is in the open state, the rotary door 21 is interposed between the water filling mechanism 30 and the sterilizing unit 50 (specifically, the discharge port 53a and the suction port 53b of the sterilizing unit 50). Therefore, when the user performs the water filling operation, if the water is scattered into the water supply chamber 10a by any chance, the possibility of water entering the discharge port 53a and the suction port 53b of the sterilizing unit 50 can be reduced.

If the water supply work is finished, the user leaves from the water supply chamber 10 a. At this time, the human body sensor 24 provided in the display panel 23 detects the presence or absence of a person around the refrigerator 1. Then, if the motion sensor 24 detects that the person is separated from the refrigerator 1 by a predetermined distance or more, the 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 rotational operation (i.e., clockwise). Thereby, the water supply chamber 10a is sequentially switched from the state shown in fig. 10(e) to the state shown in fig. 10(a), and finally, the state shown in fig. 10(a) is obtained.

Thereafter, for example, the clock 44 measures time, and if a predetermined time elapses, the sterilizing unit control portion 42 starts the operation of the sterilizing unit 50. The sterilizing unit 50 may be continuously operated while the rotary door 21 is in the closed state, and may be stopped after a certain period of time by measuring time by the clock 44, or may be further continuously operated after the certain period of time.

< summary of the first embodiment >

As described above, the refrigerator 1 of the present embodiment is equipped with the beverage supply system 10. The beverage supply system 10 includes a water supply chamber 10a that rotates in the horizontal direction. In the beverage water supply system 10, the water supply chamber 10a is hidden behind the rotary door 21 in a non-use state, and the rotary door 21 is rotated and the water supply chamber 10a is exposed in a front face in a use state.

Therefore, if the beverage supply system 10 according to the present embodiment is configured, the water supply chamber 10a is exposed to the outside in a non-use state, and therefore, it is possible to suppress adhesion of dust, dirt, and the like to the water filling port 31. Thus, a more hygienic beverage supply system can be provided.

In addition, in a state where the beverage supply system 10 is not in use, the water injection mechanism of the water supply chamber 10a is not exposed to the outside, and thus the design of the external 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 substantially located on the same plane, so that the appearance of the refrigerator 1 when not in use can be further improved.

The beverage supply system 10 of the present embodiment is provided with a sterilizing unit 50. Therefore, the propagation of bacteria and microorganisms in the water supply chamber 10a can be suppressed, and a more sanitary beverage supply system can be provided.

In the beverage supply system 10 of the present embodiment, the sterilizing unit 50 releases the sterilizing substance into the water supply chamber 10a when the rotary door 21 is in the closed state. This reduces the possibility that the substance for sterilization released into water supply chamber 10a is released into the open space. Therefore, the concentration of the bacteria-removing substance in the water supply chamber 10a can be easily maintained within an appropriate range. That is, the concentration of the bacteria removing substance in the water supply chamber 10a can be set to a concentration at which a desired bacteria removing effect is obtained. Further, the concentration of the substance for sterilization in the water supply chamber 10a can be maintained at a concentration at which there is no safety problem.

In addition, for example, substances having a peculiar odor are also included in the substances for sterilization, such as ozone and the like. If such a substance for sterilization is released to an open space, the possibility of diffusion of odor becomes high. In contrast, according to the beverage supply system 10 of the present embodiment, when the water supply chamber 10a is exposed on the front, since the operation of the sterilizing unit 50 is stopped, the diffusion of the sterilizing substance into the open space is suppressed. Therefore, the possibility of diffusion of the odor can be reduced. For example, when ozone is contained in the substance for sterilization, the average ozone concentration in the water supply chamber 10a is preferably 0.05ppm or less, and the maximum ozone concentration in the water supply chamber 10a is preferably 0.1ppm or less.

In the beverage supply system 10 of the present embodiment, the rotary door 21 of the water supply chamber 10a is opened from the side where the object detection sensor 22 is disposed. In this way, the usability of the beverage supply system 10 can be improved by combining the position of the object detection sensor 22 and the rotational 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 these. For example, the object detection sensor may be disposed on the right side of the beverage supply system, and the beverage supply system may be configured to rotate clockwise.

< second embodiment >

The description is continued with respect to a second embodiment of the present invention. In the second embodiment, the configuration of the sterilizing unit of the beverage supply system provided only in the refrigerator 1 is different from that of the first embodiment. Therefore, the following description focuses on a configuration different from that of the first embodiment.

Fig. 11 and 12 show a configuration of a beverage supply system 110 according to a second embodiment. Fig. 11 and 12 are cross-sectional views taken along line a-a of the door 2 shown in fig. 2. Fig. 11 shows a state where the swing door 21 is closed. Fig. 12 shows a state where the swing door 21 is opened.

The beverage supply system 110 is formed in its outer shape by the front cover 12 and the back cover 13. In this space, a water supply chamber (housing chamber) 10a is provided. A water filling mechanism 30 (discharge unit) for discharging water in the water tank 70 to the glass G of the user U or the like is housed in the water supply chamber 10 a. The water supply chamber 10a includes, as main components, a bottom 15, an upper mounting member 16, a back plate 17, side plates 19(a right side plate 19R and a left side plate 19L), and a rotary shaft 18. These components can be applied to the same configuration as that of the first embodiment.

Further, a sterilization unit 150 is provided on the back surface side of the back cover 13. The sterilizing unit 150 is provided in a space obtained by hollowing out a part of the heat insulating material 14. The degerming unit 150 is disposed at a substantially central portion of the water supply chamber 10a in front view (see fig. 2), as in the first embodiment.

The degerming unit 150 includes an ionizer 151, a fan 152, an upper flow path 153, a lower flow path 154, a circulation flow path 155, and the like. The ionizer 151 and the fan 152 are applied to the same configuration as the ionizer 51 and the fan 52.

The upper flow path 153 and the lower flow path 154 are located on the inner side of the back cover 13. The upper flow passage 153 is a flow passage inclined upward from the ionizer 151. A discharge port 153a through which the substances for sterilization discharged from the ionizer 151 flow into the water supply chamber 10a is formed in the upper flow passage 153. The lower flow passage 154 is a flow passage inclined downward from the ionizer 151. A discharge port 154a is formed in the lower flow passage 154 to allow the substance for sterilization discharged from the ionizer 151 to flow into the water supply chamber 10 a. The circulation flow path 155 is disposed upstream of the ionizer 51. The circulation flow path 155 is provided with a suction port 155b through which the gas in the water supply chamber 10a flows out to the bacteria removing unit side. The discharge port 153a, the discharge port 154a, and the suction port 155b are formed by providing opening portions in the rear cover 13.

According to the above configuration, when the rotary door 21 is in the closed state, the upper flow passage 153, the lower flow passage 154, and the circulation flow passage 155 are in a state of communication with the water supply chamber 10 a. Further, the upper flow path 153 discharges the substance for sterilization from the ionizer 151 obliquely upward. Further, the lower flow path 154 discharges the substance for sterilization from the ionizer 151 obliquely downward (refer to an arrow in fig. 11). Further, the gas in the water supply chamber 10a is collected from the suction port 155b provided below the water supply chamber 10 a. Further, by rotating the fan 152, the air is circulated between the water supply chamber 10a and the

flow passages

153, 154, and 155, and the moisture remaining in the water supply chamber 10a can be easily evaporated.

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 53 a. In contrast, in the second embodiment, the suction port 155b is disposed further downward (e.g., at substantially the same height as the bottom 15 of the water supply chamber 10 a). With this configuration, more gas circulating between the water supply chamber 10a and the

flow passages

153, 154, and 155 can be transmitted to the lower side of the water supply chamber 10 a.

In the beverage supply system 110, the sterilizing unit 150 operates to release the sterilizing substance into the water supply chamber 10a when the rotary door 21 is in the closed state (see fig. 11), and stops operating when the rotary door 21 is in the open state (see fig. 12), as in the first embodiment. This reduces the possibility that the substance for sterilization released into water supply chamber 10a is released into the open space other than water supply chamber 10 a. Therefore, the concentration of the bacteria-removing substance can be easily maintained within an appropriate range in the water supply chamber 10 a.

As described above, in the beverage supply system 110 of the present embodiment, the two

discharge ports

153a and 154a are provided in the sterilizing unit 50. This enables the substance for sterilization to be released to a wider range of the water supply chamber 10 a. More specifically, the substance for sterilization released from the discharge port 153a can be released to the water filling port 31. Further, the substance for sterilization released from the discharge port 154a may be released to the lower side of the water supply chamber 10 a.

In addition to the above, for example, a plurality of ionizers may be provided at different places to release the substance for sterilization to different places of the water supply chamber 10 a. Further, the blowing direction of the fan can be changed to discharge the substance for sterilization in a plurality of directions of the water supply chamber 10 a. At this time, it is preferable to release the substance for sterilization to the water pouring port 31 of the water pouring mechanism 30 and the bottom portion 15 where water is likely to accumulate, respectively.

< third embodiment >

The description is continued with respect to a third embodiment of the present invention. In the third embodiment, the configuration of the sterilizing unit of the beverage supply system provided only in the refrigerator 1 is different from that of the first embodiment. Therefore, the following description focuses on a configuration different from that of the first embodiment.

Fig. 13 and 14 show a configuration of a beverage supply system 210 according to a third embodiment.

Fig. 13 and 14 are cross-sectional views taken along line a-a of the door 2 shown in fig. 2.

Fig. 13 shows a state in which the swing door 21 is closed. Fig. 14 shows a state where the swing door 21 is opened.

The beverage supply system 210 is formed in its outer shape by the front cover 12 and the back cover 13. In this space, a water supply chamber (housing chamber) 10a is provided. A water filling mechanism 30 (discharge unit) for discharging water in the water tank 70 to the glass G of the user U or the like is housed in the water supply chamber 10 a. The water supply chamber 10a includes, as main components, a bottom 15, an upper mounting member 16, a back plate 17, side plates 19(a right side plate 19R and a left side plate 19L), and a rotary shaft 18. These components can be applied to the same configuration as that of the first embodiment.

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

The sterilizing unit 250 is composed of an ionizer 251, a fan 252, a gas flow passage 253, and the like. The ionizer 251 and the fan 252 are applied to the same configuration as the ionizer 51 and the fan 52 of the first embodiment.

The gas flow passage 253 is located on the inner side of the back cover 13. The gas passage 253 is provided with a discharge port 253a for discharging the substances for sterilization from the ionizer 251 into the water supply chamber 10a, and a suction port 253b for discharging the gas in the water supply chamber 10a to the sterilization unit side. The discharge port 253a and the suction port 253b are formed by providing openings in the rear cover 13. Thus, when the rotary door 21 is closed, the gas passage 253 and the water supply chamber 10a are in a state of communication.

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 53 a. In contrast, in the third embodiment, the suction port 253b is disposed further downward (e.g., at substantially the same height as the bottom 15 of the water supply chamber 10 a). According to this configuration, the gas circulating between the water supply chamber 10a and the gas passage 253 can be more spread to the lower side of the water supply chamber 10 a.

In the beverage supply system 210, the sterilizing unit 250 operates to release the sterilizing substance into the water supply chamber 10a when the rotary door 21 is in the closed state (see fig. 13), and stops operating when the rotary door 21 is in the open state (see fig. 14), as in the first embodiment. This reduces the possibility that the substance for sterilization released into water supply chamber 10a is released into the open space other than water supply chamber 10 a. Therefore, the concentration of the bacteria-removing substance can be easily maintained within an appropriate range in the water supply chamber 10 a.

< fourth embodiment >

The description is continued with respect to a fourth embodiment of the present invention. In the fourth embodiment, the configuration of the sterilizing unit of the beverage supply system provided only in the refrigerator 1 is different from that of the first embodiment. Therefore, the following description focuses on a configuration different from that of the first embodiment.

Fig. 15 and 16 show a configuration of a beverage supply system 310 according to a fourth embodiment. Fig. 15 and 16 are cross-sectional views taken along line a-a of the door 2 shown in fig. 2. Fig. 15 shows a state where the swing door 21 is closed. Fig. 16 shows a state where the swing door 21 is opened.

The beverage supply system 310 is formed in its outer shape by the front cover 12 and the back cover 13. In this space, a water supply chamber (housing chamber) 10a is provided. A water filling mechanism 30 (discharge unit) for discharging water in the water tank 70 to the glass G of the user U or the like is housed in the water supply chamber 10 a. The water supply chamber 10a includes, as main components, a bottom 15, an upper mounting member 16, a back plate 17, side plates 19(a right side plate 19R and a left side plate 19L), and a rotary shaft 18. These components can be applied to the same configuration as that of the first embodiment. However, the water filling handle 332 of the water filling mechanism 30 is different from that of the first embodiment in that no opening is formed.

In the present embodiment, the arrangement position of the degerming unit 350 is different from that of the first embodiment. As shown in fig. 15, the sterilization unit 350 is provided above the rear side (i.e., the back panel 17 side) of the rotary door 21. Further, the sterilizing unit 350 is not constituted by an ionizer, but is constituted by a UV irradiator. Therefore, ultraviolet rays are emitted from the sterilizing unit 350 as a substance for sterilization. Since ultraviolet rays have a sterilization effect, the ultraviolet rays emitted from the sterilization unit 350 are irradiated to the water filling port 31 and the like, whereby the propagation of bacteria, mold, and the like existing around the water filling port 31 can be suppressed. The wavelength of the ultraviolet rays to be irradiated is, for example, 400nm or less. Preferably, ultraviolet rays having a wavelength range of 250nm to 300nm are used.

Further, in the beverage supply system 310, the sterilizing unit 350 operates and irradiates ultraviolet rays (refer to fig. 15) when the rotary door 21 is in the closed state, and stops operating (irradiation of ultraviolet rays) when the rotary door 21 is in the open state (refer to fig. 16). Thus, when water supply chamber 10a is exposed to the front, irradiation of ultraviolet rays harmful to the human body can be stopped.

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

< modification of the third embodiment >

Next, a modification of the third embodiment will be described. Fig. 17 shows a configuration of a beverage supply system 310' according to a modification. The sterilization method in the beverage supply system 310' is different from that of the third embodiment. Specifically, sterilization is performed in the beverage supply system 310' using a photocatalyst and light.

As shown in fig. 17, in the beverage supply system 310 ', a photocatalyst layer 355' is formed around the water filling port 31 at the front end portion of the water filling mechanism 30. The photocatalyst layer 355' is a photocatalyst, and includes, for example, titanium oxide. Further, the beverage supply system 310 'includes a light irradiator as the sterilization unit 350'. Ultraviolet rays or visible rays are emitted from the light irradiator. If light irradiated from the photo irradiator is irradiated to the photocatalyst layer 355 ', OH radicals are generated from the photocatalyst layer 355'. Since OH radicals have strong oxidizing power, they can kill bacteria and microorganisms present on the surface.

Further, in the beverage supply system 310 ', the sterilizing unit 350' operates and irradiates light (refer to fig. 17) when the rotary door 21 is in the closed state, and stops operating (irradiation of light) when the rotary door 21 is in the open state, as in the third embodiment.

< fifth embodiment >

The fifth embodiment of the present invention will be described. In the above-described respective embodiments, an example in which the beverage supply system is built in the refrigerator is described. However, the beverage supply system according to the embodiment of the present invention is not necessarily built in the refrigerator, and may be installed separately in, for example, a gym, a sports facility, a hospital, or the like. Therefore, an example in which the beverage supply system is provided separately is explained in the mode of the present embodiment.

Fig. 18(a) shows an external configuration of a beverage supply system 400 according to the present embodiment. Fig. 18(a) shows a state in which the beverage supply system 400 is used. Fig. 18(b) shows an internal structure of the beverage supply system 400.

The beverage supply system 400 includes a display panel 401, a water supply chamber 10a, a water tank 70, an object detection sensor 422, and a display panel 423. The water supply chamber 10a is applied to the same configuration as that of the first embodiment.

The beverage supply system 400 is provided with a sterilizing unit 50. When the rotary door 21 is in the open state, the sterilizing unit 50 is present on the back surface plate 17 and the back side of the rotary door 21. That is, when the rotary door 21 is in the open state, the rotary door 21 and the back panel 17 are interposed between the water filling port 31 and the sterilizing unit 50. Therefore, when the rotary door 21 is in the open state, the sterilizing unit 50 is not visible from the front. In fig. 18, the sterilizing unit 50 is shown in broken lines for convenience.

As shown in fig. 18(b), the rotary door 421 is provided as a part of the structure of the water supply chamber 10 a. Specifically, the swing door 421 is disposed to overlap the back panel 17.

The beverage supply system 400 is configured such that the rotary door 421 horizontally rotates if the object detection sensor 422 detects a hand of a user or the like. If the rotary door 421 is rotated, the water supply chamber 10a appears on the front surface. The method of controlling the opening/closing operation of the swing door 421 is applied to the same configuration as the beverage supply system 10 according to the first embodiment.

Further, in the beverage supply system 400, the sterilizing unit 50 operates when the rotary door 421 is in the closed state and releases the substance for sterilization into the water supply chamber 10a, and stops operating when the rotary door 21 is in the open state, as in the first embodiment. This reduces the possibility that the substance for sterilization released into water supply chamber 10a is released into the open space. Therefore, the concentration of the sterilizing substance can be easily maintained within an appropriate range in the water supply chamber 10 a.

< sixth embodiment >

The above-described rotary structure of the water supply chamber in the beverage supply system is applicable not only to the beverage supply system but also to a refrigerator in which a small rotary door is provided in a part of a main door of the refrigerator and a small storage box (a storage system with a door) is provided on the back surface of the rotary door. Such a small-sized storage case can accommodate one or more beverages (e.g., milk boxes, beverage boxes, tea in PET bottles, and soft drinks).

If a beverage with a higher frequency of use is stored in such a small-sized storage case, a desired beverage can be taken out from the revolving door without opening the main door of the refrigerator. By taking out the beverage from the revolving door in this way, the temperature rise in the refrigerator can be suppressed as compared with the case where the beverage is taken out after the main door is opened. Further, by providing the small-sized storage box at a lower position, even a small child can easily take out the beverage from the revolving door.

In a sixth embodiment, an example of a configuration in which the door-equipped storage system according to an embodiment of the present invention is applied to a small locker attached to a refrigerator will be described. Fig. 19(a) to 19(c) show a refrigerator 500 according to a sixth embodiment.

As shown in fig. 19(a), the refrigerator 500 includes a small-sized locker 510, a display panel 523, and the like in a door 502 of a refrigerating chamber. The small-sized locker 510 includes a swing 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 box 510.

As shown in fig. 19(b), a storage chamber (housing chamber) 510a is provided on the back surface side of the revolving door 521. The storage chamber 510a can store one or a plurality of beverages (e.g., milk boxes, beverage boxes, tea from PET bottles, soft drinks, etc.), for example.

The small-sized locker 510 is configured such that the swing door 521 is horizontally rotated if the object detection sensor 522 detects a hand of a user or the like. If the swing door 521 is rotated, the storage compartment 510a appears to the front as shown in fig. 19 (c). In the present embodiment, the object detection sensor 522 is disposed on the right side of the revolving door 521. Therefore, if the object detection sensor 522 detects the hand of the user or the like, the revolving door 521 rotates in the opposite direction (i.e., clockwise) to the revolving door 21 of the first embodiment. Further, in the case where the object detection sensor 522 is disposed on the left side of the revolving door 521, as in the first embodiment, it is preferable that the revolving door 521 is rotated counterclockwise to be in an open state.

If a beverage that is used more frequently is stored in the small-sized locker 510, a desired beverage can be taken out from the swing door 521 without opening the door 502 of the refrigerator 500. By taking out the beverage from the revolving door 521 in this way, the temperature rise in the refrigerator can be suppressed as compared with the case of taking out the beverage after opening the door 502. Further, by providing the swing door 521 of the small-sized locker 510 at a lower position, even a small child can easily take out the beverage from the swing door 521.

The small-sized storage box 510 according to the present embodiment includes the sterilization unit 50 in the same manner as the first embodiment. When the rotary door 521 is in the open state, the sterilization unit 50 is present on the back panel and the back side of the rotary door 521. Therefore, when the swing door 521 is in the open state, the sterilizing unit 50 is in the invisible state from the front. In FIG. 19(c), the degerming unit 50 is shown in phantom for convenience.

In the small-sized locker 510, the sterilizing unit 50 operates when the swing door 521 is in the closed state to release the sterilizing substance into the locker room 510a, and stops operating when the swing door 21 is in the open state, as in the present embodiment. This reduces the possibility that the substance for sterilization released into the storage chamber 510a is released into the open space. Therefore, the concentration of the sterilizing substance in the storage chamber 510a can be easily maintained within an appropriate range.

The embodiments disclosed herein are illustrative and not restrictive in all respects. The scope of the present invention is indicated by the scope of the claims, rather than the description above, and is intended to include all modifications within the scope and meaning equivalent to the scope of the claims. In addition, configurations obtained by combining the configurations of the different embodiments described in the present specification are also included in the scope of the present invention.
