[0011] Hereinafter, embodiments will be described in detail with reference to the drawings. However, excessive detailed description may be omitted in some cases. For example, detailed descriptions of already well-known matters or overlapping descriptions for substantially the same configuration may be omitted.

[0012] The accompanying drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0013] (Embodiment 1) Hereinafter, Embodiment 1 will be described with reference to FIGS. 1 to 11. The washing machine according to Embodiment 1 is mainly for washing beverage containers. Since the vending machine described in Patent Document 1 is for selling drinking water, it is not assumed that hard-to-remove dirt adheres to the inside of the container. In contrast, when reusing containers for selling coffee beverages, tea, juice, etc., it is necessary to inject the washing liquid into the inside of the container with a stronger force to remove hard-to-remove dirt. Therefore, when washing a container, techniques are required to seal the container to prevent the washing liquid from leaking from the inside of the container, and to hold the container to prevent it from being blown off by the injection of the washing liquid.

[0014] [1-1. Configuration] FIG. 1 shows the configuration of the washing machine 1 according to Embodiment 1 and the procedure of a method for washing a container B by the washing machine 1. The washing machine 1 includes a main body 2, a nozzle 3, a seal portion 4, a holding portion 5, a pump 9, a tank 10, and a control device 50.

[0015] The nozzle 3 is provided inside an opening 8 of the main body 2, and injects a washing liquid for washing the inside of the container B. The seal portion 4 seals to prevent the washing liquid injected into the container B from leaking from between the container B and the main body 2.

[0016] The holding portion 5 holds the container B so that the container B is in contact with the seal portion 4. The holding portion 5 is provided so as to be movable up and down along a guide 6 attached to the main body 2. A user can grip a handle 7 attached to the holding portion 5 to move the holding portion 5 up and down. A configuration for automatically moving the holding portion 5 up and down along the guide 6 may be provided.

[0017] The pump 9 sucks up the washing liquid from the tank 10 that stores the washing liquid and causes the nozzle 3 to inject the washing liquid. The control device 50 controls the driving of the pump 9. The pump 9, the tank 10, and the control device 50 are omitted in the following drawings.

[0018] In step (a), the user grasps the handle 7 and moves the holding part 5 so that the height of the holding part 5 from the top surface of the main body 2 is higher than the height of the container B. Next, the user turns the container B upside down and inserts it into the holding part 5 from below. The user inserts the container B into the holding part 5 until it is directly below (directly above in Figure 1) the protrusion C provided on the side of the container B.

[0019] In step (b), the user chucks the side of container B with the holding part 5. The holding part 5 has an inner surface that is the same shape as the outer surface of the side of container B, and surrounds and holds the side of container B. The holding part 5 may be opened and closed manually, for example, by the user pushing, pulling, or twisting the handle 7. A configuration for automatically opening and closing the holding part 5 may be provided. The holding part 5 may be biased in the direction of chucking container B. In this case, after the user manually opens the holding part 5 and inserts container B into the holding part 5, the container B can be automatically chucked by releasing the handle 7 or pressing a button for chucking container B. Once the user confirms that container B is chucked by the holding part 5, they grasp the handle 7 and move the holding part 5 downwards.

[0020] In step (c), the user lowers the holding part 5 until the container B and the sealing part 4 come into contact, and presses the container B against the sealing part 4. This seals the space between the container B and the main body 2 so that the cleaning liquid injected into the container B does not leak out from between the container B and the main body 2.

[0021] When the container B is chucked by the holding part 5 and the container B comes into contact with the sealing part 4, the control device 50 drives the pump 9 to inject the cleaning liquid from the nozzle 3. The cleaning liquid that enters the inside of the container B through the opening E of the drinking spout D of the container B is discharged into the inside of the main body 2 through the opening E by gravity. The pump 9 may be powered when the container B comes into contact with the sealing part 4. The pump 9 may be powered when the holding part 5 comes into contact with the container B, and also when the container B comes into contact with the sealing part 4. The pump 9 may be driven by the user pressing a start button or the like after the pump 9 has been powered. The pump 9 may be stopped when the container B comes into contact with the sealing part 4, or when the holding part 5 comes into contact with the container B.

[0022] A sensor may be provided to detect that the container B is chucked by the holding part 5. A sensor may also be provided to detect that the container B is in contact with the sealing part 4. These sensors may be, for example, contact sensors, pressure sensors, or optical sensors. The control device 50 may acquire detection results from these sensors and control the on / off status of the pump 9 according to the detection results.

[0023] The inner diameter of the holding part 5 is larger than the outer diameter of the side of container B below the holding position (above in Figure 1) and smaller than the outer diameter above the holding position (below in Figure 1). When the cleaning liquid is injected into the inside of container B, the cleaning liquid hits the inner bottom surface of container B, causing an upward force to act on container B in Figure 1. However, since the outer diameter of the side of container B above the holding position is smaller than the inner diameter of the holding part 5, the upward movement of container B in Figure 1 is prevented. In the example in Figure 1, a protrusion C is provided on the side of container B, and the holding part 5 holds container B below the protrusion C (above in Figure 1). Therefore, even if an upward force acts on container B due to the cleaning liquid, the protrusion C catches on the holding part 5, preventing the upward movement of container B. As a result, container B is held so as not to separate from the seal part 4 during cleaning, preventing cleaning water from leaking between container B and the main body 2. Therefore, the safety of the cleaning machine 1 can be ensured. Furthermore, by inserting container B into the holding part 5 from the bottom and setting it in the washing machine 1, the possibility of the drinking spout D coming into contact with the holding part 5 is reduced, thus ensuring greater hygiene.

[0024] The sealing portion 4 is provided to seal the space between the container B below the drinking spout D (above in Figure 1) and the main body 2. This allows the cleaning solution to reach the outside of the drinking spout D, thus cleaning both the inside and outside of the drinking spout D. Therefore, even if the container B is used multiple times or shared by multiple users, it can be kept hygienic. Furthermore, even when a container B used exclusively by a single user is cleaned in a washing machine 1 shared by multiple users, the container B can be cleaned without the drinking spout D touching the holding portion 5 or other parts, thus ensuring greater hygiene.

[0025] The washing machine 1 shown in Figure 1 does not wash the outside of the sides and bottom of the container B below the point of contact with the seal portion 4, but only washes the inside of the container B and the outside of the drinking spout D. Therefore, as long as the container B and the main body 2 are sealed to prevent water leakage, there is no need to provide a housing to cover the container B. This allows for a simplified configuration while ensuring the safety of the washing machine 1.

[0026] Figure 2 shows the configuration of the washing machine 1 according to Embodiment 1 and another example of the procedure for washing container B using the washing machine 1. In the example shown in Figure 1, container B was inserted into the holding part 5 from below, but in the example shown in this figure, container B is inserted into the holding part 5 from above.

[0027] In step (a), the user turns container B upside down and moves it above the holding part 5.

[0028] In step (b), the user opens the holding part 5 such that the inner diameter of the holding part 5 is wider than the outer diameter of the protrusion C of the container B.

[0029] In step (c), the user inserts container B into the holding part 5 from above. The user inserts container B into the holding part 5 until it is directly below (directly above in Figure 2) the protrusion C provided on the side of container B.

[0030] In step (d), the user uses the holding part 5 to chuck the part of the container B directly below (directly above in Figure 2) the protrusion C on the side surface.

[0031] In step (e), the user lowers the holding part 5 until the container B and the sealing part 4 come into contact, and presses the container B against the sealing part 4.

[0032] As shown in the example in this figure, the distance the holding part 5 moves up and down can be shortened. This allows the guide 6 to be shortened. Furthermore, user convenience can be improved.

[0033] Figure 3 shows the configuration of the washing machine 1 according to Embodiment 1 and another example of the procedure for washing container B using the washing machine 1. In the example shown in Figure 3, the container B is inserted into the holding part 5 and the chuck is fastened, and the sealing is completed at the same time.

[0034] In step (a), the user turns container B upside down and moves it above the holding part 5.

[0035] In step (b), the user opens the holding part 5 such that the inner diameter of the holding part 5 is wider than the outer diameter of the protrusion C of the container B.

[0036] In step (c), the user inserts container B into the holding part 5 from above. The user inserts container B into the holding part 5 until it is directly below (directly above in Figure 3) the protrusion C provided on the side of container B. At this time, the distance between the holding part 5 and the sealing part 4, and the width of the protrusion C are adjusted so that the area directly above (directly below in Figure 3) the protrusion C of container B contacts the sealing part 4.

[0037] In step (d), the user uses the holding part 5 to chuck the container B directly below (directly above in Figure 3) the protrusion C on the side of the container B. This allows the chuck of the container B by the holding part 5 and the sealing between the container B and the main body 2 by the sealing part 4 to be completed simultaneously.

[0038] In the example shown in this figure, there is no need to move the holding part 5 up and down. Therefore, the guide 6 can be omitted. This also improves user convenience.

[0039] Furthermore, as shown in the example in this figure, even containers B with different heights and capacities can be cleaned by the same washing machine 1 if the shape of the upper part (lower part in Figures 4A and 4B) of the protrusion C is the same.

[0040] Figure 5 shows the configuration of the washing machine 1 according to Embodiment 1 and another example of the procedure for washing container B using the washing machine 1. In the example shown in Figure 5, the container B is inserted into the holding part 5 and the chuck is fastened, and the sealing is completed at the same time.

[0041] In step (a), the user turns container B upside down and moves it above the holding part 5.

[0042] In step (b), the user inserts container B into the holding part 5 from above. At this time, the sloping part above (below in Figure 5) the convex part C of container B pushes the holding part 5 open.

[0043] In step (c), the user pushes down container B until the area directly above (directly below in Figure 5) the protrusion C of container B comes into contact with the sealing portion 4.

[0044] In step (d), when the protrusion C passes the holding part 5, the holding part 5, which is biased in the closing direction, automatically chucks the area directly below (directly above in Figure 5) the protrusion C. At this time, the distance between the holding part 5 and the sealing part 4, and the width of the protrusion C are adjusted so that the area directly above (directly below in Figure 5) the protrusion C of the container B comes into contact with the sealing part 4. This allows the chuck of the container B by the holding part 5 and the sealing between the container B and the main body 2 by the sealing part 4 to be completed simultaneously.

[0045] In the example shown in this figure, there is no need to move the holding part 5 up and down. Therefore, the guide 6 can be omitted. This also improves user convenience.

[0046] Figure 6 shows the configuration of the washing machine 1 according to Embodiment 1 and another example of the procedure for washing container B using the washing machine 1. In the example shown in Figure 6, container B is set in the main body 2 and then chucked by the holding part 5.

[0047] In step (a), the user places container B upside down on the main body 2. At this time, the seal portion 4 is in contact with the protrusion C on the side of container B (directly above, or directly below, in Figure 6).

[0048] In step (b), the user lowers the holding part 5 to directly below (directly above in Figure 6) the protrusion C on the side of container B and chucks container B. If the outer diameter of container B below (above in Figure 6) the protrusion C is smaller than the outer diameter of container B at the holding position, the holding part 5 can be lowered to the holding position and chucked without opening or closing the holding part 5. If the outer diameter of a portion of container B below (above in Figure 6) the protrusion C is larger than the outer diameter of container B at the holding position, the holding part 5 is opened once, lowered to the holding position, and then the holding part 5 is closed at the holding position to chuck container B.

[0049] As illustrated in this diagram, the steps that the user must perform can be simplified, thereby improving user convenience.

[0050] Figure 7 shows the configuration of the washing machine 1 according to Embodiment 1 and another example of the procedure for washing container B using the washing machine 1. In the example shown in Figure 7, the holding part 5 and the sealing part 4 are integrally configured compared to the example shown in Figure 1.

[0051] In step (a), the user grasps the handle 7 and moves the holding part 5 so that the height of the holding part 5 from the top surface of the main body 2 is higher than the height of the container B. Next, the user turns the container B upside down and inserts it into the holding part 5 from below. The user inserts the container B into the holding part 5 until it is directly below (directly above in Figure 1) the protrusion C provided on the side of the container B, and the holding part 5 chucks the side of the container B.

[0052] In step (b), the user lowers the retaining part 5 until the sealing part 4 and the main body 2 come into contact.

[0053] As shown in the example in this figure, the procedure performed by the user can be simplified, thereby improving user convenience. Furthermore, since the holding part 5 and the sealing part 4 are integrated, the configuration of the washing machine 1 can be simplified.

[0054] Figure 8 shows the configuration of the washing machine 1 according to Embodiment 1 and another example of the procedure for washing container B using the washing machine 1. In the example shown in Figure 8, the holding part 5 and the sealing part 4 are integrally configured. Also, in the example shown in Figure 8, the holding part 5 is pivotally supported on the main body 2.

[0055] In step (a), the user grasps the handle 7 and rotates the holding part 5 to the right in Figure 8 to open it. Next, the user turns the container B upside down and inserts it into the holding part 5 from the lower left.

[0056] In step (b), the user inserts container B into the holding part 5 up to just below (directly above in Figure 8) the protrusion C provided on the side of container B, and the holding part 5 chucks the side of container B.

[0057] In step (c), the user grasps the handle 7 and rotates the holding part 5 to the left in Figure 8 to bring the sealing part 4 into contact with the main body 2.

[0058] As shown in the example in this figure, the procedure performed by the user can be simplified, thereby improving user convenience. In addition, since the holding part 5 and the sealing part 4 are integrally constructed, the configuration of the washing machine 1 can be simplified. Furthermore, by inserting the container B into the holding part 5 from the bottom and setting it in the washing machine 1, the possibility of the drinking spout D coming into contact with the holding part 5 is reduced, thus ensuring greater hygiene.

[0059] Figures 9A and 9B show another example of container B according to Embodiment 1. In the example shown in Figure 9A, a recess F is provided on the side of container B. The holding part 5 surrounds and holds the side of container B in the recess F. This prevents the container B from moving up, down, left, or right when the cleaning liquid is injected into the container B. In this case as well, if the shape of the upper part (lower part in Figure 9A) of the recess F is kept the same, containers B of different heights and capacities can be cleaned by the cleaning machine 1 shown in Figure 3 or Figure 5.

[0060] In the example shown in Figure 9B, the side surface of container B has a shape in which the outer diameter gradually increases from the bottom surface towards the drinking spout D. This prevents container B from moving upwards or sideways when the cleaning solution is injected into it.

[0061] Figure 10 shows the configuration of a control device 50 for controlling the cleaning machine 1 according to Embodiment 1. The control device 50 is implemented using hardware such as a microcomputer, microcontroller, and integrated circuit. This figure shows the configuration of a control device 50 for automatically controlling a pump 9 for ejecting cleaning fluid from a nozzle 3.

[0062] The control device 50 includes a contact state information acquisition unit 51 and a pump control unit 52. These configurations are implemented hardware-wise by the CPU, memory, and other LSIs of any computer, and software-wise by programs loaded into memory, but here we are describing functional blocks that are realized through the cooperation of these components. Therefore, it will be understood by those skilled in the art that these functional blocks can be implemented in various forms, such as hardware only or a combination of hardware and software.

[0063] The contact state information acquisition unit 51 acquires information indicating the holding state from the holding state sensor 11, which detects the holding state of the container B by the holding unit 5. The contact state information acquisition unit 51 also acquires information indicating the sealing state from the sealing state sensor 12, which detects the contact state between the container B and the sealing unit 4.

[0064] The pump control unit 52 controls the on / off state of the pump 9 based on the information acquired by the contact state information acquisition unit 51. When the container B and the seal portion 4 are in contact, the pump control unit 52 enables the pump 9 to be turned on to eject the cleaning liquid from the nozzle 3, and when the container B and the seal portion 4 are not in contact, it turns off the pump 9 to prevent the cleaning liquid from being ejected from the nozzle 3. This prevents the cleaning liquid from leaking outside the container B.

[0065] The pump control unit 52 enables the pump 9 to be turned on to eject cleaning fluid from the nozzle 3 when the container B is held by the holding unit 5, and turns off the pump 9 to prevent cleaning fluid from being ejected from the nozzle 3 when the container B is not held by the holding unit 5. This prevents the container B from being ejected from the main body 2 and hitting surrounding objects or the user due to the cleaning fluid being ejected into the container B.

[0066] [1-2. Operation] The operation and function of the washing machine 1, configured as described above, will be explained below.

[0067] Figure 11 is a flowchart showing the procedure of the cleaning method according to the embodiment. The user sets the container B to be cleaned into the cleaning machine 1 (S10). The container B is held by the holding part 5 while the sealing part 4 and the container B are in contact by any method, including the method described above. The contact state information acquisition unit 51 of the control device 50 acquires information indicating the holding state from the holding state sensor 11, which detects the holding state of the container B by the holding part 5. When the container B is held by the holding part 5 (Y in S12), the pump control unit 52 enables the pump 9 to be turned on in order to eject the cleaning liquid from the nozzle 3. When the container B is not held by the holding part 5 (N in S12), the pump control unit 52 stops the pump 9 if it is running (S20) and then terminates the process. The contact state information acquisition unit 51 acquires information indicating the sealing state from the sealing state sensor 12, which detects the contact state between the container B and the sealing part 4. The pump control unit 52 enables the pump 9 to be turned on to inject cleaning fluid from the nozzle 3 when the container B and the seal portion 4 are in contact (Y in S14). When the container B and the seal portion 4 are not in contact (N in S14), the pump control unit 52 stops the pump 9 if it is running (S20) and then terminates the process. The pump control unit 52 drives the pump 9 to inject cleaning fluid from the nozzle 3 (S16). Until cleaning is complete (N in S18), it returns to S12 and continues cleaning. When cleaning is complete after a predetermined time or after a predetermined amount of cleaning fluid has been injected (Y in S18), the pump control unit 52 stops the pump 9 (S20). When the cleaning fluid inside the container B is discharged into the main body 2, the user releases the holding part 5 and removes the container B from the main body 2.

[0068] [1-3. Effects, etc.] As described above, in this embodiment, the washing machine 1 comprises a main body 2, a nozzle 3 for injecting a cleaning solution for cleaning the inside of container B, a sealing part 4 for sealing to prevent the cleaning solution injected into container B from leaking between container B and the main body 2, and a holding part 5 for holding container B so that it contacts the sealing part 4. This makes it possible to simplify the configuration of the washing machine 1 while ensuring the safety of the washing machine 1.

[0069] Furthermore, in this embodiment, the holding part 5 holds the container B so that it does not separate from the sealing part 4 when the cleaning liquid is injected into the container B from the nozzle 3. This makes it possible to simplify the configuration of the cleaning machine 1 while ensuring the safety of the cleaning machine 1.

[0070] Furthermore, in this embodiment, the container B and the sealing portion 4 come into contact, thereby energizing the pump for dispensing the cleaning solution from the nozzle 3. This improves the safety of the cleaning machine 1.

[0071] Furthermore, in this embodiment, when the container B and the sealing portion 4 separate, the pump 9 for injecting the cleaning solution from the nozzle 3 is stopped. This improves the safety of the cleaning machine 1.

[0072] Furthermore, in this embodiment, the holding part 5 holds the container B on its side. This allows for a simplification of the washing machine 1's configuration while ensuring the safety of the washing machine 1.

[0073] Furthermore, in this embodiment, the holding part 5 holds the container B below the protrusion C provided on the side surface of the container B. This makes it possible to simplify the configuration of the washing machine 1 while ensuring the safety of the washing machine 1.

[0074] Furthermore, in this embodiment, the holding portion 5 surrounds the container B on its side surface, and the inner diameter of the holding portion 5 is larger than the outer diameter of the side surface below the holding position where the holding portion 5 holds the container B, and smaller than the outer diameter of the side surface above the holding position. This allows for a simplification of the washing machine 1's configuration while ensuring the safety of the washing machine 1.

[0075] Furthermore, in this embodiment, the sealing portion 4 seals the space between the main body 2 and the side portion below the drinking spout D provided in the opening E of the container B. This allows the outside of the drinking spout D to be cleaned as well.

[0076] Furthermore, in this embodiment, the control device 50 includes a contact state information acquisition unit 51 that acquires information indicating the contact state between the container B and the sealing part 4, which seals the container B to prevent the cleaning liquid injected into the container B from leaking out from between the container B and the main body 2 of the cleaning machine 1 for cleaning the inside of the container B, and a pump control unit 52 that enables the injection of cleaning liquid into the inside of the container B when the sealing part 4 and the container B are in contact, and controls the injection of cleaning liquid into the inside of the container B when the sealing part 4 and the container B are not in contact. This makes it possible to simplify the configuration of the cleaning machine 1 while ensuring the safety of the cleaning machine 1.

[0077] Furthermore, in this embodiment, the control method includes the steps of bringing a sealing part 4, which seals the container B to prevent the cleaning liquid injected into the container B from leaking from between the container B and the main body 2 of the cleaning machine 1 for cleaning the inside of the container B, into contact with the container B, and injecting the cleaning liquid into the inside of the container B while the sealing part 4 and the container B are in contact. This makes it possible to simplify the configuration of the cleaning machine 1 while ensuring the safety of the cleaning machine 1.
