Description

Cleaning device for metal container
Technical Field
The present invention relates to a cleaning device for a metal container.
Background
For example, in a metal container (hereinafter, simply referred to as a container) such as a magic bottle or a table pot, discolored dirt adheres to the inner surface of the container due to repeated storage of beverages (contents) such as coffee, tea, and soup. Such dirt is not completely removed but gradually deposited on the inner surface of the container when cleaning such as washing with water or a neutral detergent is repeated, and cannot be easily removed even by wiping with a sponge or the like. In this case, the inside of the container needs to be cleaned with a cleaning liquid in which an oxygen-containing bleaching agent or the like is dissolved.
However, in cleaning using an oxygen-containing bleaching agent, it takes a very long time to immerse the cleaning liquid in the container in advance for several hours to ten or more hours. Therefore, the requirement for cleaning the container in a short time cannot be satisfied.
Therefore, a method has been proposed in which cleaning liquid in a container is electrolyzed and fouling in the container is removed in a short time by hydroxyl radicals generated at the time (for example, see patent document 1). Specifically, patent document 1 discloses a cleaning apparatus including: a voltage is applied between the positive electrode and the negative electrode in a state where an electrode rod serving as the positive electrode is immersed in the cleaning liquid in the container and an electrode tab or an electrode arm serving as the negative electrode is in contact with an upper edge or an inner wall surface of the container, the electrode rod being provided on an upper surface of the container.
Patent document 1: japanese patent No. 5667674
However, in the above-described conventional cleaning device, it is necessary to bring the electrode tab or the electrode arm serving as the negative electrode into contact with the metal portion of the container at the time of cleaning. However, in the case of a cleaning device using an electrode sheet for a negative electrode, it cannot be used in a type in which the upper end edge of the container is covered with a cover member (insulating member) such as plastic. On the other hand, in the case of a cleaning apparatus using an electrode arm for a negative electrode, the cleaning apparatus cannot be used for a type in which the tip of the electrode arm cannot reach the inner wall surface of a container (is in non-contact) such as a type in which the nozzle edge of the container is narrow.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(embodiment 1)
First, as embodiment 1 of the present invention, for example, a cleaning apparatus 1A shown in fig. 1 and 2 will be described. Fig. 1 is a perspective view showing the structure of the cleaning apparatus 1A. Fig. 2 is an exploded perspective view showing the structure of the cleaning apparatus 1A.
In the cleaning apparatus 1A of the present embodiment, a cleaning liquid containing an oxygen-containing bleaching agent is poured into the inside of a metal container having an open top surface, and the dirt adhering to the inner surface of the metal container is decomposed and removed by hydroxyl radicals generated by the electrolysis of the cleaning liquid.
Specifically, the cleaning apparatus 1A includes an apparatus main body 2 having a substantially flat cylindrical shape as a whole. The apparatus main body 2 includes a main body case 5 dividable into a lower case 3 and an upper case 4. The lower case 3 of the main body case 5 is formed of an insulating member made of plastic having a bottom wall 3a and a peripheral wall 3 b. On the other hand, the upper case 4 is formed of a plastic insulating member having a top wall 4a and a peripheral wall 4 b.
A plurality of (2 in this example) locking holes 6a are provided in the peripheral wall 3b of the lower case 3. On the other hand, the peripheral wall 4b of the upper case 4 is provided with a plurality of (2 in this example) locking claws 6 b. In the main body case 5, the plurality of locking claws 6b are locked to the plurality of locking holes 6a, whereby the upper case 4 can be detachably assembled to the lower case 3 in a state where the peripheral walls 3b and 4b are butted against each other.
A center hole (hole portion) 7 penetrating the device body 2 in the thickness direction is provided in the center of the body case 5. The center hole 7 is formed by a sleeve portion 3c formed upright from the bottom wall 3a of the lower case 3 and a hole portion 4c penetrating the top wall 4a of the upper case 4.
A battery case 8 and a circuit board 9 are provided inside the main body case 5. The battery case 8 is provided on the bottom wall 3a of the lower case 3. The battery case 8 accommodates a plurality of (3 in this example) batteries B, and connects the plurality of batteries B in series via a plurality of connection terminals 10. The battery case 8 may be provided on the top wall 4a of the upper case 4.
The circuit board 9 is attached to the top wall 4a side of the upper case 4, and is electrically connected to the battery case 8 when the upper case 4 is assembled to the lower case 3. The circuit board 9 includes at least a positive electrode and a negative electrode, and constitutes a power supply circuit for applying a voltage between the positive electrode and the negative electrode. In addition, the circuit board 9 is provided with a timer that stops (turns off) the operation of the power supply circuit after a lapse of a constant time.
A power switch 11 and a power lamp 12 are provided on the upper surface of the main body case 5. The power switch 11 is provided on the top wall 4a of the upper case 4 and electrically connected to the circuit board 9. The power switch 11 switches electrical connection (on/off) between the battery case 8 and the circuit substrate 9 by its pressing operation.
The power lamp 12 is provided on the top wall 4a of the upper case 4 and electrically connected to the circuit board 9. The power supply lamp 12 is controlled by the circuit board 9 so as to be lit only during the operation of the power supply circuit (the conduction between the positive electrode and the negative electrode).
The cleaning apparatus 1A includes, as components constituting a power supply circuit including the circuit board 9, an electrode rod 13 electrically connected to a positive electrode, and a 1 st electrode arm 14a and a 2 nd electrode arm 14b electrically connected to a negative electrode.
The electrode rod 13 is made of a long metal rod (conductive member) such as stainless steel. The electrode rod 13 is slidably inserted into the center hole 7 of the device body 2. The electrode rod 13 is configured such that a plastic cap (insulating member) 15 is attached to both ends thereof in a state inserted into the center hole 7. The electrode rod 13 is electrically connected to the positive electrode side of the circuit board 9 by being in contact with a contact terminal (not shown) provided in the center hole 7 (hole 4 c).
The 1 st electrode arm 14a and the 2 nd electrode arm 14b are formed of a metal rod (conductive member) such as stainless steel, for example. The 1 st electrode arm 14a and the 2 nd electrode arm 14b are rotatably attached to the lower surface (bottom wall 3a) of the apparatus main body 2 via a hinge portion 16.
The hinge portion 16 is provided at a position offset from the center of the lower surface of the device main body 2 (bottom wall 3 a). The 1 st electrode arm 14a and the 2 nd electrode arm 14b are extended from the hinge portion 16 in the same direction.
The hinge portion 16 has a pair of hinge shafts 16a, 16b passing through shaft holes 14c, 14d provided on the base end sides of the 1 st electrode arm 14a and the 2 nd electrode arm 14 b; and a bearing portion 16c on the side of the device main body 2 (bottom wall 3a) for pivotally supporting the pair of hinge shafts 16a, 16b, and the hinge portion 16 rotatably supports the 1 st electrode arm 14a and the 2 nd electrode arm 14 b. Further, the spacer member 16d is disposed between the base end sides of the 1 st electrode arm 14a and the 2 nd electrode arm 14b in a sandwiched state. Thereby, the 1 st electrode arm 14a and the 2 nd electrode arm 14b can be integrally rotated in a state of being parallel to each other.
A 1 st torsion spring (1 st urging member) 17a and a 2 nd torsion spring (2 nd urging member) 17b that urge the 1 st electrode arm 14a and the 2 nd electrode arm 14b in a direction separating them from the lower surface (bottom wall 3a) of the apparatus main body 2 are provided inside the hinge portion 16. The hinge portion 16 that accommodates the 1 st torsion spring (1 st urging member) 17a and the 2 nd torsion spring (2 nd urging member) 17b is attached to the lower case 3 by being attached from below the bottom wall 3 a. For example, the hinge portion 16 may be attached to the lower case 3 by providing a protrusion at the upper end of the hinge shafts 16a and 16b and fixing the protrusion to the lower side of the bottom wall 3 a. The 1 st electrode arm 14a and the 2 nd electrode arm 14b are rotatable within an angular range of 90 ° or more (about 120 ° in this example) with respect to the lower surface (bottom wall 3a) of the apparatus main body 2 by the biasing force of the 1 st torsion spring 17a and the 2 nd torsion spring 17 b.
The 1 st electrode arm 14a is electrically connected to the negative electrode side of the battery case 8 via a 1 st torsion spring 17a made of metal. The 2 nd electrode arm 14b is electrically connected to the negative electrode side (ground line) of the circuit board 9 via a 2 nd torsion spring 17b made of metal. The 1 st electrode arm 14a and the 2 nd electrode arm 14b are electrically insulated from each other. Thus, the power supply circuit of the circuit board 9 is not operated (turned on) only by the pressing operation of the power switch 11, and when the 1 st electrode arm 14a and the 2 nd electrode arm 14b are electrically connected via the metal containers 100 and 200 described later, the power supply circuit of the circuit board 9 is first operated (turned on), and the power supply between the positive electrode and the negative electrode can be confirmed by lighting the power lamp 12.
A locking portion 18 is provided on the lower surface (bottom wall 3a) of the apparatus main body 2. The locking portion 18 is located on the opposite side of the hinge portion 16, and has a pair of protruding portions 19a, 19b protruding to face each other. Further, a pair of projections 20a and 20b are provided on the surfaces of the pair of projections 19a and 19b facing each other. On the other hand, the 1 st electrode arm 14a and the 2 nd electrode arm 14b are provided with holes 21a and 21b into which the pair of projections 20a and 20b engage.
In the cleaning device 1A, the projections 20a and 20b on the projection portions 19a and 19b side are engaged with the hole portions 21A and 21b on the 1 st electrode arm 14a and the 2 nd electrode arm 14b side in a state where the 1 st electrode arm 14a and the 2 nd electrode arm 14b are rotated in a direction approaching the lower surface (bottom wall 3a) of the device main body 2 against the biasing force of the 1 st torsion spring 17a and the 2 nd torsion spring 17 b. This allows the 1 st electrode arm 14a and the 2 nd electrode arm 14b to be locked in a state facing the lower surface (bottom wall 3a) of the device body 2.
As an example of a method of cleaning a metal container using the cleaning apparatus 1A having the above-described configuration, a case of cleaning the metal container 100 shown in fig. 3 will be described. Fig. 3 is a cross-sectional view showing an example of a usage mode of the cleaning apparatus 1A.
The metal container 100 shown in fig. 3 is a so-called table pot, and includes a container main body 101 having an open upper surface. The container body 101 has a vacuum heat insulating structure, and can keep warm or cool the beverage (contents) contained in the container body 101. A plastic cover member (insulating member) 102 covering the upper end edge is attached to the container main body 101. The cover member 102 is provided with a pouring spout 102a and a handle 102 b.
When the metal container 100 is cleaned by using the cleaning apparatus 1A of the present embodiment, first, a cleaning liquid (not shown) containing an oxygen-containing bleaching agent is injected into the inside of the container main body 101. This causes the dirt adhering to the inner wall surface of the container main body 101 to be immersed in the cleaning liquid.
Next, the apparatus main body 2 is set on the upper surface of the container main body 101 in a state where the 1 st electrode arm 14a and the 2 nd electrode arm 14b rotated in a direction of separating from the lower surface (bottom wall 3a) of the apparatus main body 2 are brought into contact with the metal portion of the inner wall surface of the container main body 101 while the electrode rod 13 is inserted into the cleaning liquid in the container main body 101.
At this time, the 1 st and 2 nd electrode arms 14a and 14b biased by the 1 st and 2 nd torsion springs 17a and 17b are pressed against the inner wall surface of the container main body 101.
Next, the power switch 11 is pressed. Thereby, the power supply lamp 12 is turned on, and a voltage is applied between the electrode rod 13 and the 1 st electrode arm 14a and the 2 nd electrode arm 14 b.
This allows the cleaning liquid in the container main body 101 to be electrolyzed, and the hydroxy radicals generated at this time can remove the dirt adhering to the inner wall surface of the container main body 101 in a short time.
In the cleaning device 1A of the present embodiment, after a predetermined time (for example, 3 minutes) has elapsed by the timer, the power supply lamp 12 is turned off, and the application of the voltage is stopped. When the metal container 100 is insufficiently cleaned, the power switch 11 may be pressed again to repeat cleaning of the metal container 100.
As another example of the method of cleaning a metal container using the cleaning apparatus 1A of the present embodiment, a case of cleaning a metal container 200 shown in fig. 4, for example, will be described. Fig. 4 is a cross-sectional view showing another example of the usage of the cleaning apparatus 1A.
The metal container 200 shown in fig. 4 is a so-called thermos cup (Mug Bottle) and includes a container body 201 having an open upper surface. The container body 201 has a vacuum heat insulating structure, and can keep warm or cool the beverage (contents) contained in the container body 201. The container body 201 has a shape in which the diameter of the mouth-and-neck portion 201b is reduced as compared with the body portion 201 a. The metal container 200 is different from the metal container 100 in that an upper edge portion of the container main body 201 is not covered with a cover member (insulating member) and a metal portion is exposed.
When the metal container 200 is cleaned by using the cleaning apparatus 1A of the present embodiment, first, a cleaning liquid (not shown) containing an oxygen-containing bleaching agent is injected into the inside of the container main body 201. This causes the dirt adhering to the inner wall surface of the container main body 201 to be immersed in the cleaning liquid.
Next, the apparatus main body 2 is set on the upper surface of the container main body 201 in a state where the electrode rod 13 is inserted into the cleaning liquid in the container main body 201 and the 1 st electrode arm 14a and the 2 nd electrode arm 14b locked to the lower surface (bottom wall 3a) of the apparatus main body 2 by the locking portion 18 are brought into contact with the metal portion of the upper end edge of the metal container 200.
Next, the power switch 11 is pressed. Thereby, the power supply lamp 12 is turned on, and a voltage is applied between the electrode rod 13 and the 1 st electrode arm 14a and the 2 nd electrode arm 14 b.
This allows the cleaning liquid in the container main body 201 to be electrolyzed, and the hydroxy radicals generated at this time to remove the dirt adhering to the inner wall surface of the container main body 201 in a short time.
In the cleaning device 1A of the present embodiment, after a predetermined time (for example, 3 minutes) has elapsed by the timer, the power supply lamp 12 is turned off, and the application of the voltage is stopped. When the metal container 200 is insufficiently cleaned, the power switch 11 may be pressed again to repeat cleaning of the metal container 200.
As described above, the cleaning device 1A of the present embodiment can be widely applied to cleaning of different metal containers 100 and 200 of different types such as the above-described table pot and the thermos cup.
(embodiment 2)
Next, as embodiment 2 of the present invention, for example, a cleaning apparatus 1B shown in fig. 5 (a) and (B) will be described. In the following description, the same portions as those of the above-described cleaning apparatus 1A are not described, and the same reference numerals are given to the drawings.
Fig. 5 (a) is a perspective view showing a state in which the electrode arms 14a and 14B of the cleaning apparatus 1B are positioned downward. Fig. 5 (B) is a perspective view showing a state in which the electrode arms 14a and 14B of the cleaning apparatus 1B are positioned above each other.
The cleaning apparatus 1B of the present embodiment has basically the same configuration as the above-described cleaning apparatus 1A except that the 1 st electrode arm 14a and the 2 nd electrode arm 14B are arranged differently. That is, in the cleaning apparatus 1B, the hinge portion 16 is provided at the center of the lower surface of the apparatus main body 2 (the bottom wall 3 a).
In the present embodiment, the center hole 7 is provided in a state of penetrating the hinge portion 16, but the 1 st torsion spring 17a and the 2 nd torsion spring 17b (negative side) provided in the hinge portion 16 and the contact terminal (positive side) provided in the center hole 7 are electrically insulated from each other.
The 1 st electrode arm 14a and the 2 nd electrode arm 14b are extended from the hinge portion 16 in opposite directions. The 1 st electrode arm 14a and the 2 nd electrode arm 14b are rotatable in opposite directions to each other in an angular range of 90 ° or more (about 120 ° in this example) with respect to the lower surface (bottom wall 3a) of the apparatus main body 2 by the biasing force of the 1 st torsion spring 17a and the 2 nd torsion spring 17 b.
The device main body 2 is provided with a 1 st accommodation recess 22a and a 2 nd accommodation recess 22b on a lower surface (bottom wall 3 a). In the cleaning apparatus 1B, the 1 st electrode arm 14a and the 2 nd electrode arm 14B can be accommodated inside the 1 st accommodating recess 22a and the 2 nd accommodating recess 22B in a state where the 1 st electrode arm 14a and the 2 nd electrode arm 14B are rotated in a direction approaching the lower surface (bottom wall 3a) of the apparatus main body 2 against the biasing force of the 1 st torsion spring 17a and the 2 nd torsion spring 17B. The 1 st electrode arm 14a and the 2 nd electrode arm 14b accommodated inside the 1 st accommodating recess 22a and the 2 nd accommodating recess 22b are in a state of being flush with the lower surface (bottom wall 3a) of the apparatus main body 2 or slightly protruding from the lower surface (bottom wall 3a) of the apparatus main body 2.
Further, a locking portion 18 is provided on the lower surface (bottom wall 3a) of the apparatus main body 2. The locking portion 18 has a pair of projections 20a and 20b inside the 1 st accommodation recess 22a and the 2 nd accommodation recess 22b (although the projection 20b is not shown in fig. 5 (a) and (b)). The pair of projections 20a and 20b are provided to project from side surfaces of the 1 st accommodation recess 22a and the 2 nd accommodation recess 22b facing the 1 st electrode arm 14a and the 2 nd electrode arm 14 b. On the other hand, the 1 st electrode arm 14a and the 2 nd electrode arm 14b are provided with holes 21a and 21b into which the pair of projections 20a and 20b engage.
As an example of a method of cleaning a metal container using the cleaning apparatus 1B having the above-described configuration, a case of cleaning a metal container 100 shown in fig. 6, for example, will be described. Fig. 6 is a cross-sectional view showing an example of a usage mode of the cleaning apparatus 1B.
When the metal container 100 is cleaned by using the cleaning apparatus 1B of the present embodiment, first, a cleaning liquid (not shown) containing an oxygen-containing bleaching agent is injected into the inside of the container main body 101. This causes the dirt adhering to the inner wall surface of the container main body 101 to be immersed in the cleaning liquid.
Next, the apparatus main body 2 is set on the upper surface of the container main body 101 in a state where the 1 st electrode arm 14a and the 2 nd electrode arm 14b rotated in a direction of separating from the lower surface (bottom wall 3a) of the apparatus main body 2 are brought into contact with the metal portion of the inner wall surface of the container main body 101 while the electrode rod 13 is inserted into the cleaning liquid in the container main body 101.
At this time, the 1 st and 2 nd electrode arms 14a and 14b biased by the 1 st and 2 nd torsion springs 17a and 17b are pressed against the inner wall surface of the container main body 101.
Next, the power switch 11 is pressed. Thereby, the power supply lamp 12 is turned on, and a voltage is applied between the electrode rod 13 and the 1 st electrode arm 14a and the 2 nd electrode arm 14 b.
This allows the cleaning liquid in the container main body 101 to be electrolyzed, and the hydroxy radicals generated at this time can remove the dirt adhering to the inner wall surface of the container main body 101 in a short time.
In the cleaning apparatus 1B according to the present embodiment, after a predetermined time (for example, 3 minutes) has elapsed by the timer, the power supply lamp 12 is turned off, and the application of the voltage is stopped. When the metal container 100 is insufficiently cleaned, the power switch 11 may be pressed again to repeat cleaning of the metal container 100.
As another example of the method of cleaning a metal container using the cleaning apparatus 1B of the present embodiment, a case of cleaning a metal container 200 shown in fig. 7, for example, will be described. Fig. 7 is a cross-sectional view showing another example of the usage of the cleaning apparatus 1B.
When the metal container 200 is cleaned by using the cleaning apparatus 1B of the present embodiment, first, a cleaning liquid (not shown) containing an oxygen-containing bleaching agent is injected into the inside of the container main body 201. This causes the dirt adhering to the inner wall surface of the container main body 201 to be immersed in the cleaning liquid.
Next, the cleaning liquid in which the electrode rod 13 is inserted into the container body 201 is set on the upper surface of the container body 201 in a state where the 1 st electrode arm 14a and the 2 nd electrode arm 14b, which are locked to the lower surface (bottom wall 3a) of the device body 2 by the locking portions 18, are in contact with the metal portion of the upper end edge of the metal container 200 in a state of being accommodated inside the 1 st accommodating recess 22a and the 2 nd accommodating recess 22 b.
Next, the power switch 11 is pressed. Thereby, the power supply lamp 12 is turned on, and a voltage is applied between the electrode rod 13 and the 1 st electrode arm 14a and the 2 nd electrode arm 14 b.
This allows the cleaning liquid in the container main body 201 to be electrolyzed, and the hydroxy radicals generated at this time to remove the dirt adhering to the inner wall surface of the container main body 201 in a short time.
In the cleaning apparatus 1B according to the present embodiment, after a predetermined time (for example, 3 minutes) has elapsed by the timer, the power supply lamp 12 is turned off, and the application of the voltage is stopped. When the metal container 200 is insufficiently cleaned, the power switch 11 may be pressed again to repeat cleaning of the metal container 200.
As described above, the cleaning device 1B of the present embodiment can be widely applied to cleaning of different metal containers 100 and 200 of different types such as the above-described table pot and the thermos cup.
The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.
For example, the cleaning devices 1A and 1B are configured to include the 2 electrode arms 14a and 14B, but may be configured by 1 electrode arm in some cases. In addition, the number of electrode arms can be increased (to 3 or more).
In the cleaning apparatuses 1A and 1B, the 1 st electrode arm 14a and the 2 nd electrode arm 14B may be connected to an extension electrode arm, a bendable electrode arm, or an extendable electrode arm. In the case of such a configuration, the tip of the electrode arm can be brought into contact with the bottom surface of the container main body 101 or 201. Further, the present invention is not limited to a metal container having a narrow opening compared to the diameter of the apparatus main body 2, and can also be applied to a metal container having a wide opening compared to the diameter of the apparatus main body 2.
In the cleaning apparatuses 1A and 1B, power is supplied from the battery B housed in the battery case 8, but alternatively, power may be supplied by being connected to an external power supply. Further, a battery (secondary battery) housed in the apparatus main body 2 may be charged by an external power supply, and electric power may be supplied from the battery.
The metal container to be cleaned is not limited to the container having the container main body 101 or 201 having the vacuum heat insulating structure such as the metal container 100 or 200, and the cleaning apparatus of the present invention can be widely applied to a metal container in which the cleaning liquid in the electrolytic capacitor and the hydroxyl radicals generated at this time can decompose and remove the dirt in the container.
