[0003] [[Patent Document 1]] Japanese Patent Application Laid-Open No. 11-111945 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]
[0004] However, with conventional drying devices, there are variations in the insertion depth of hands among different users, such as some users insert hands shallower and some insert deeper, and as a result, variations in drying state may occur. In particular, when washing hands with liquid, the inventor has found that the cleaning state varies greatly depending on the insertion depth and insertion position of the hands.
[0005] The present disclosure is based on the inventor's finding, and provides a handwashing device capable of maintaining a uniform handwashing state even for a plurality of users. [[Means for Solving the Problem]]
[0006] One hand-washing device according to the present invention is a hand-washing device comprising an insertion part that forms an insertion space into which at least one hand can be inserted, a first nozzle which is a nozzle that discharges liquid to the back of the hand inserted into the insertion space, a second nozzle which is a nozzle that discharges liquid to the palm of the hand inserted into the insertion space, a detection means for detecting that a hand has been inserted into the insertion space to a predetermined depth and the distance between the hand inserted into the insertion space and at least one of the first nozzle and the second nozzle, a state changing device for changing the liquid discharge state from the first nozzle and the liquid discharge state from the second nozzle, and a control device for controlling the hand-washing device, wherein the control device comprises an information acquisition unit that acquires hand position information from the detection means, and a discharge control unit that controls the state changing device when a hand has been inserted to a predetermined depth based on the hand position information, thereby enabling the discharge of liquid in a state corresponding to the distance from at least one of the first nozzle and the second nozzle to the hand. [Effects of the Invention]
[0007] According to this disclosure, it is possible to achieve a handwashing condition with reduced variability, even when used by different users. [Brief explanation of the drawing]

[Modes for carrying out the invention]
[0009] The following describes embodiments of the hand-washing apparatus according to the present invention with reference to the drawings. The following embodiments are provided as examples to illustrate the present invention and are not intended to limit it. For example, the shapes, structures, materials, components, relative positional relationships, connection states, numerical values, formulas, the content of each step in the method, and the order of each step shown in the following embodiments are examples and may include content not described below. Geometric expressions such as parallel and orthogonal may be used, but these expressions do not indicate mathematical rigor and include substantially acceptable errors and deviations. Similarly, expressions such as simultaneous and identical also include substantially acceptable ranges.
[0010] Furthermore, the drawings are schematic diagrams that have been appropriately emphasized, omitted, or had their proportions adjusted to illustrate the present invention, and therefore differ from the actual shapes, positional relationships, and proportions. Also, the X, Y, and Z axes shown in the drawings represent orthogonal coordinates arbitrarily set for the purpose of explaining the drawings. In other words, the Z axis is not necessarily an axis along the vertical direction, and the X and Y axes are not necessarily located in the horizontal plane.
[0011] Furthermore, in the following, multiple inventions may be described comprehensively as a single embodiment. Also, some of the content described below is described as an optional component relating to the present invention.
[0012] Furthermore, the flowchart is merely an example, and embodiments of the present invention may include cases where the order of processing differs, multiple processes are integrated, or a single process is separated.
[0013] Figure 1 is a perspective view showing the external appearance of the handwashing device 100 with the user's hand 200 inserted. Figure 2 is a simplified diagram showing a cross-section of the handwashing device 100 with the user's hand 200 inserted. The handwashing device 100 is a device that automatically washes the user's hand by dispensing liquid onto the user's hand 200, and comprises an insertion section 110, a first nozzle 121, a second nozzle 122, a detection means 130 (see Figure 3), a state changing device 140 (see Figure 3), and a control device 150. In this embodiment, the handwashing device 100 also comprises a functional liquid manufacturing device 160, a drying means, a drainage means 180, and an notification device 101.
[0014] The insertion section 110 is the part that forms an insertion space 111 into which at least one of the user's hands 200 is inserted. In this embodiment, the insertion space 111 is rectangular and large enough to allow both of the user's hands 200 to be inserted side by side (aligned along the X-axis in the figure). Furthermore, the insertion space 111 is inclined downwards (in the Z-direction in the figure) toward a direction away from the user's body (in the Y-direction in the figure). This makes it easier for the user to insert their hands 200 into the insertion space 111. In this embodiment, a drainage means 180 is provided at the bottom of the insertion section 110. The drainage means 180 collects the liquid discharged from the first nozzle 121 and the second nozzle 122 inside the insertion section 110 and discharges it outside the handwashing device 100.
[0015] The first nozzle 121 is a nozzle that discharges liquid to the back of the hand 200 (including the back of the fingers of the hand 200) when the hand is inserted into the insertion space 111. The first nozzle 121 is positioned on the side of the insertion section 110 that is further away from the user than the second nozzle 122 (the Y- side in the figure), and its discharge port opens toward the insertion space 111. In this embodiment, the first nozzle 121 is positioned closer to the insertion port of the insertion section 110 than the second nozzle 122, and is tilted to discharge liquid away from the insertion port of the insertion section 110 so that liquid does not come out of the insertion port. The liquid discharged by the first nozzle 121 is not limited. Examples of liquids include water, alcohol, or water or alcohol with a substance added to enhance the cleaning effect. The liquid may be stored in a tank or the like, or water supplied from a tap may be modified.
[0016] The number of first nozzles 121 provided in the handwashing device 100 is not limited. In this embodiment, at least two first nozzles 121 are arranged side by side in the lateral direction (X-axis direction in the figure) to correspond to each of the two hands 200 inserted into the insertion space 111. The liquid discharge state of the first nozzles 121 is not limited. For example, the first nozzles 121 may discharge (spray) the liquid in a mist, or discharge the liquid in a columnar shape. Alternatively, the mist or columnar liquid may be discharged in a fan shape, or in a hollow cone shape or a solid cone shape.
[0017] The second nozzle 122 is a nozzle that discharges liquid towards the palm side of the hand 200 (including the palm-side surface of the fingers) of the hand 200 inserted into the insertion space 111. The second nozzle 122 is positioned on the side of the insertion section 110 closer to the user than the first nozzle 121 (Y+ side in the figure), and its discharge port opens towards the insertion space 111. In this embodiment, the second nozzle 122 is positioned closer to the bottom of the insertion section 110 than the first nozzle 121, and is positioned to discharge liquid upward. The liquid discharged by the second nozzle 122 is the same as the liquid discharged from the first nozzle 121.
[0018] The number of second nozzles 122 provided in the hand washing apparatus 100 is not limited. In the present embodiment, at least two second nozzles 122 are arranged side by side in the lateral direction (the X-axis direction in the drawings) so as to respectively correspond to both hands 200 inserted into the insertion space 111. The liquid discharge state of the second nozzles 122 is not limited. For example, the second nozzles 122 may discharge (spray) liquid in an atomized state, or may discharge liquid in a columnar shape. Further, the atomized liquid or columnar liquid may be discharged in a fan shape, and may also be discharged in a hollow conical shape or a solid conical shape. The discharge state may be the same as or different from that of the first nozzles 121.
[0019] The detection means 130 detects that the hand 200 has been inserted into the insertion space 111 to a predetermined depth, and detects the distance between the hand 200 inserted into the insertion space 111 and at least one of the first nozzle 121 and the second nozzle 122. In the present embodiment, the hand washing apparatus 100 includes a first detection means 131 and a second detection means 132 as the detection means 130.
[0020] The first detection means 131 detects that the hand 200 has been inserted into the insertion space 111 to a predetermined depth. The type of the first detection means 131 is not limited. For example, the first detection means 131 may detect in a non-contact manner that the fingertips of the hand 200 have reached a predetermined insertion depth. Further, the first detection means 131 may measure how far the hand is inserted from the bottom of the insertion portion 110, and detect the insertion depth of the hand 200 by performing threshold judgment on the measured value. The specific detection method of the first detection means 131 is not limited. Examples include a method of detecting the insertion depth by blocking light, a method of detecting the insertion depth by emitting light and receiving reflected light reflected by the hand 200, and a method of detecting the insertion depth by emitting ultrasonic waves or radio waves and receiving the ultrasonic waves or radio waves reflected by the hand 200.
[0021] In the present embodiment, the first detection means 131 is disposed on the surface of the insertion portion 110 on the side closer to the user than the first nozzle 121 (the Y+ side in the drawings), detects whether a hand 200 has been inserted to a predetermined depth, and outputs the detection result as hand position information. The number of first detection means 131 provided in the handwashing device 100 is not limited. In the present embodiment, at least two first detection means 131 are arranged side by side in the lateral direction (the X-axis direction in the drawings) so as to respectively detect the insertion depths of both hands 200 inserted into the insertion space 111.
[0022] The second detection means 132 detects the distance between the hand 200 inserted into the insertion space 111 and the inner peripheral surface of the insertion portion 110, and outputs the detection result as hand position information. The specific method for detecting distance by the second detection means 132 is not limited. Examples thereof include a method of detecting insertion depth by emitting light and receiving reflected light reflected by the hand 200, and a method of detecting insertion depth by emitting ultrasonic waves or radio waves and receiving the ultrasonic waves or radio waves reflected by the hand 200.
[0023] In the present embodiment, the first detection means 131 is disposed near the first nozzle 121. This enables accurate measurement of the distance between the first nozzle 121 and the hand 200. The number of second detection means 132 provided in the handwashing device 100 is not limited. In the present embodiment, at least two second detection means 132 are arranged side by side in the lateral direction (the X-axis direction in the drawings) so as to respectively detect the distances between the two first nozzles 121 and the hand 200.
[0024] The state changing device 140 changes the discharge state of the liquid from the first nozzle 121 and the discharge state of the liquid from the second nozzle 122 according to the distance detected by the second detection means 132. For example, the state changing device 140 changes at least one of the discharge rate per unit time and the discharge pressure of the liquid discharged from the first nozzle 121 and the second nozzle 122. The state changing device 140 is not limited to, and exemplifies, for example, an adjustment valve that adjusts the opening area through which the liquid passes. In this embodiment, the hand washing device 100 includes a first state changing device 141 and a second state changing device 142 as the state changing device 140. The first state changing device 141 and the second state changing device 142 are pumps that can pressurize and deliver liquid. The first state changing device 141 independently changes the state of the liquid discharged from the first nozzle 121, and the second state changing device 142 independently changes the state of the liquid discharged from the second nozzle 122.
[0025] The functional liquid manufacturing device 160 is a device that imparts or enhances cleaning function to the liquid supplied to the hand washing device 100. The type of functional liquid manufacturing device 160 is not limited. For example, examples of the functional liquid manufacturing device 160 include an ozone water manufacturing device, an electrolyzed water manufacturing device, a hypochlorous acid water manufacturing device, and a detergent additive device.
[0026] The drying device 170 (see Figure 3) is inserted into the insertion space 111 and dries the hand 200, which has liquid on it, by blowing air onto it. The drying device may dry the hand 200 by discharging air at room temperature, or by discharging heated air. In this embodiment, the drying device is equipped with a first drying nozzle 171 and a second drying nozzle 172.
[0027] The first drying nozzle 171 is a nozzle that discharges air to the back of the hand 200 inserted into the insertion space 111. The first drying nozzle 171 is located on the inner surface of the insertion section 110 on the side further away from the user than the second drying nozzle 172 (Y-side in the figure), and its discharge port opens toward the insertion space 111. In this embodiment, the first drying nozzle 171 is located closer to the insertion port of the insertion section 110 than the second nozzle 122. The number of first drying nozzles 171 provided in the hand washing device 100 is not limited. For example, the first drying nozzle 171 may extend throughout the entire lateral direction (X-axis direction in the figure) inside the insertion section 110. Also, at least two first drying nozzles 171 may be arranged side by side in the lateral direction to correspond to each of the two hands 200 inserted into the insertion space 111. The air discharge state of the first drying nozzle 171 is not limited. For example, the first drying nozzle 171 may discharge air as a thin film, such as what is called an air knife.
[0028] The second drying nozzle 172 is a nozzle that discharges air towards the palm side of the hand 200 inserted into the insertion space 111. The second drying nozzle 172 is located on the inner surface of the insertion section 110 on the side closer to the user than the first drying nozzle 171 (Y+ side in the figure), and its discharge port opens toward the insertion space 111. In this embodiment, the second drying nozzle 172 is located opposite the first drying nozzle 171, which is closer to the insertion port of the insertion section 110 than the second nozzle 122. The number of second drying nozzles 172 provided in the hand washing device 100 is not limited. For example, the second drying nozzles 172 may extend throughout the entire lateral direction (X-axis direction in the figure) inside the insertion section 110. Also, at least two second drying nozzles 172 may be arranged side by side in the lateral direction to correspond to each of the two hands 200 inserted into the insertion space 111. The air discharge state of the second drying nozzles 172 is not limited. For example, the second drying nozzle 172 may discharge air as a thin film, similar to the first drying nozzle 171, which is sometimes referred to as an air knife.
[0029] Figure 3 is a block diagram showing the functional configuration of the hand-washing device 100. The control device 150 is a device that controls the hand-washing device 100. The control device 150 includes a processor and, as a processing unit realized by having the processor execute a washing program, includes an information acquisition unit 151 and a discharge control unit 152. In this embodiment, the control device 150 also includes a drying control unit 153 and a notification unit 154 as processing units. Note that in Figure 1, the electrical wiring connecting the control device 150 and each device is omitted.
[0030] The information acquisition unit 151 acquires hand position information from the detection means 130, namely the first detection means 131 and the second detection means 132. In this embodiment, the first detection means 131 acquires hand position information indicating that the hand 200 has reached a predetermined depth, and the second detection means 132 acquires hand position information indicating the distance between the first nozzle 121 and the back of the hand 200.
[0031] The discharge control unit 152 controls the discharge of liquid from at least one of the first nozzle 121 and the second nozzle 122 by controlling the first state changing device 141 and the second state changing device 142, which are state changing devices 140, based on the hand position information acquired by the information acquisition unit 151, when the hand 200 is inserted to a predetermined depth. The discharge control unit 152 also controls the state changing device 140 according to the distance from at least one of the first nozzle 121 and the second nozzle 122 to the hand 200, and controls the discharge state of the liquid discharged from the first nozzle 121 and the second nozzle 122, respectively. For example, if the distance from the first nozzle 121 to the back of the hand 200 is shorter than the distance from the second nozzle 122 to the palm of the hand 200, the discharge control unit 152 controls the first state changing device 141 and the second state changing device 142 so that the liquid discharge force from the first nozzle 121 is less than the liquid discharge force from the second nozzle 122. The control method of the discharge control unit 152 is not limited. For example, the discharge state of the liquid coming out of the first nozzle 121 may be determined using a function whose variable is the distance from the first nozzle 121 to the back of the hand 200. Alternatively, the distance from the second nozzle 122 to the palm of the hand 200 may be derived based on the distance from the first nozzle 121 to the back of the hand 200 and the shape of the insertion part 110, and the discharge state of the liquid coming out of the second nozzle 122 may be determined using a function whose variable is the derived result.
[0032] The drying control unit 153 controls the drying device based on the hand position information acquired by the information acquisition unit 151. For example, if the distance from the first nozzle 121 to the back of the hand 200 is shorter than the distance from the second nozzle 122 to the palm of the hand 200, the drying control unit 153 controls the first state change device 141 and the second state change device 142 so that the air discharge force from the first drying nozzle 171 is less than the air discharge force from the second drying nozzle 172. In addition, when the hand 200 is withdrawn from the insertion space 111, the drying control unit 153 may alternately discharge air from the first drying nozzle 171 and the second drying nozzle 172 to dry the inner surface of the insertion section 110. By alternately discharging air from the first drying nozzle 171 and the second drying nozzle 172, interference of the discharged air can be prevented.
[0033] The notification unit 154 notifies the user of hand position information via the notification device 101. The notification method is not limited, but examples include methods of notifying hand position information by sound, light, display patterns (including characters), etc. If the hand position information includes the distance of the hand 200 to a predetermined depth, the insertion depth of the hand 200 may be notified to the user by changing the state of the light according to the distance. Alternatively, the user may be notified whether the relationship between the positions of the first nozzle 121, the second nozzle 122, and the hand 200 is appropriate based on the distance between the first nozzle 121 and the back of the hand 200 included in the hand position information.
[0034] Figure 4 is a flowchart showing the processing flow of the handwashing device 100. When a hand 200 is inserted into the handwashing device 100, the first detection means 131 detects the insertion depth of the hand 200 (S101). The notification unit 154 notifies the user of insufficient insertion via the notification device 101 until the hand 200 is inserted to a predetermined depth (S102, No) (S103). When the hand 200 is inserted to a predetermined depth (S102, Yes), the second detection means 132 detects the distance between the first nozzle 121 and the back of the hand 200 (S104). The discharge control unit 152 changes the state of the liquid discharged from the first nozzle 121 and the state of the liquid discharged from the second nozzle 122 based on the distance between the first nozzle 121 and the back of the hand 200 (S105). The discharge control unit 152 controls the state change device 140 to discharge the liquid in the changed state for a predetermined period of time (S106, No). After the liquid discharge is complete (S106, Yes), the drying control unit 153 dries the hand 200 inserted into the insertion space 111 for a predetermined period of time (S107, No). When the predetermined period is complete (S107, Yes), the notification unit 154 notifies the user via the notification device 101 that the washing and drying of the hand 200 is complete (S108). This completes the series of hand washing processes.
[0035] It should be noted that the present invention is not limited to the embodiments described above. For example, other embodiments of the present invention may be realized by arbitrarily combining the components described herein, or by excluding some of the components. Furthermore, modifications obtained by applying various modifications to the above embodiments that a person skilled in the art could conceive of without departing from the spirit of the present invention, that is, the meaning indicated by the wording in the claims, are also included in the present invention.
[0036] For example, as shown in Figure 5, the third nozzle 123 may be located deeper than the first nozzle 121 in the depth direction of the insertion portion 110, and the fourth nozzle 124 may be located shallower than the second nozzle 122.
[0037] Furthermore, the system may also include a third state changing device 143 for individually changing the liquid discharge state from the third nozzle 123, and a fourth state changing device 144 for individually changing the liquid discharge state from the fourth nozzle 124. The third state changing device 143 and the fourth state changing device 144 may be of the same type as the first state changing device 141 or different. In this example, the third state changing device 143 and the fourth state changing device 144 are pumps of the same type as the first state changing device 141 and the second state changing device 142, capable of pressurizing and dispensing liquid. In this case, the discharge control unit 152 may individually control the first state changing device 141 to the fourth state changing device 144.
[0038] Furthermore, the first detection means 131 may also be equipped with a function to measure the distance between the hand 200 and the second nozzle 122, similar to the second detection means 132. In this case, it is also possible to obtain hand position information, including that the hand 200 has reached a predetermined insertion depth and the distance between the first detection means 131 and the hand 200, using the first detection means 131 without the second detection means 132. In addition, if the first detection means 131 and the second detection means 132 are equipped with sensors capable of measuring distance, it becomes possible to change the state of the liquid discharged from the first nozzle 121 and the state of the liquid discharged from the second nozzle 122 according to differences in the thickness of the user's hand 200 and the position of the hand 200 in the depth direction (Y-axis direction in the figure).
[0039] Furthermore, although the case in which the first detection means 131 is positioned on the palm side of the hand 200 and the second detection means 132 is positioned on the back side of the hand 200 has been described, the first detection means 131 and the second detection means 132 may also be positioned on the same side of the hand 200.
[0040] Furthermore, the pipe resistance of the first pipe 125 that supplies liquid to the first nozzle 121 and the pipe resistance of the second pipe 126 that supplies liquid to the second nozzle 122 may be made different. For example, the inner diameter of the first pipe 125 from the branching section 127 to the first nozzle 121 may be made different from the inner diameter of the second pipe 126 from the branching section 127 to the second nozzle 122. For example, the inner diameter of the second pipe 126 may be smaller or larger than the inner diameter of the first pipe 125. As shown in Figure 6, if the inner diameter of the second pipe 126 is made smaller than the inner diameter of the first pipe 125, it becomes possible to change the balance between the state of the liquid discharged from the first nozzle 121 and the state of the liquid discharged from the second nozzle 122 by providing a first state changing device 141, which is a flow control valve, between the branching section 127 and the first nozzle 121. On the other hand, if the inner diameter of the second pipe 126 is larger than the inner diameter of the first pipe 125, the balance between the state of the liquid discharged from the first nozzle 121 and the state of the liquid discharged from the second nozzle 122 can be changed by providing a first state changing device 141 between the branching section 127 and the second nozzle 122. If either the flow rate or pressure of the liquid reaching the branching section 127 exceeds a predetermined value, the second state changing device 142, which is a pump, does not need to be provided.
