  First, in the case of a building 100 such as a high-rise apartment house or office building as shown in FIG. 4, the upper floor 110 has a considerable height, so the water supply hose part to the tip of the cleaning nozzle 5n that discharges water is used. The length (height) of 5 often reaches several hundred meters. Therefore, in the drainage pipe cleaning work in the upper floor 110, the water pressure supplied from the main body of the washing machine becomes considerably high, and troubles such as the middle of the water supply hose part 5 rupturing or the coupler connecting the water supply hose part 5 coming off occur. It becomes easy to do. When such a trouble occurs, the corridor or staircase in the house or building becomes flooded, so it is necessary to stop the water supply immediately, but when using a conventional drain pipe washer, The distance between the operator who operates the distal end side of the water supply hose portion 5 and the main body of the washing machine also becomes long, and as a result, there is a difficulty in not being able to sufficiently cope with such troubles.

  Secondly, the water pressure fluctuates greatly between the cleaning of the upper floor 110 and the cleaning of the lower floor 101 of the building 100. However, the fluctuation of the water pressure does not provide sufficient cleaning quality or causes unnecessary energy consumption. This is a negative factor. Therefore, it is one of the important conditions required for this type of drain pipe cleaning machine to stably maintain a predetermined water pressure without being influenced by the upper floor 110 and the lower floor 101. In the conventional drain pipe washer, the distance between the operator who operates the distal end side of the water supply hose part 5 and the main body of the washer tends to be long, so that it is difficult to adjust the water pressure easily and quickly. there were.

  Next, preferred embodiments according to the present invention will be given and described in detail with reference to the drawings.

  First, the configuration of the drain pipe cleaning system 1 according to the present embodiment will be described with reference to FIGS. 1 to 6 (FIG. 9).

  As shown in FIG. 3, the drain pipe cleaning system 1 is configured as a whole by a cleaning machine main body Mm and a mobile terminal Ms. In this case, as shown in FIG. 4, the washing machine main body Mm is mounted in a vehicle 51 of a vehicle (automobile) 50, and a smart phone H that can be carried and used by an operator is applied to the mobile terminal Ms. .

  In the illustrated example, since a one-box car is used as the vehicle 50, the operation panel 53 of the cleaning machine main body Mm is caused to face the entrance / exit portion 52o where the side slide door 52 is opened. Accordingly, various operations can be performed on the washing machine main body Mm from the outside of the vehicle with the slide door 52 opened. Furthermore, a hose winder that does not appear in the figure can be installed in the interior 51, and the water supply hose portion 5 can be led out from the inlet / outlet portion 52o as shown in FIG.

  In this case, the water supply hose portion 5 includes a hose body 5m using a flexible hose member having excellent pressure resistance and a cleaning nozzle 5n attached to the distal end of the hose body 5m. Further, as shown in FIG. 9, the hose body 5m and the cleaning nozzle 5n are inserted into various drain pipes P including linearity and non-linearity to be cleaned, and select shapes and dimensions that allow entry into the interior. Constitute. The illustrated cleaning nozzle 5n has a plurality of injection ports along the circumferential direction, and each of the injection ports can discharge (inject) the cleaning water W in the radial direction of the cleaning nozzle 5n. Thereby, the inner wall of the drain pipe P can be washed with the high-pressure washing water W jetted from the jet nozzle.

  Further, a gun valve 61 and a flow meter 62 connected in series are connected to the midway position of the hose body 5m as shown in FIG. The gun valve 61 can be operated by the operator on the distal end side of the water supply hose unit 5 and can be opened and closed by operating the trigger 61t of the gun valve 61. . Further, the operator can check the flow rate state of the cleaning water W with the flow meter 62.

  On the other hand, FIG. 3 shows the whole structure of the washing machine main body Mm. Reference numeral 2 denotes a water storage tank that stores the cleaning water W, and the cleaning water W is stored inside the water storage tank 2. Note that tap water can be used as the cleaning water W, and various cleaning liquids having a high cleaning effect can be used as the other cleaning water W. Reference numeral 3 denotes a delivery pump (high pressure pump) for delivering the wash water W of the water storage tank 2. A rear end port of the hose body 5 m is connected to a delivery port (discharge port) 3 o of the delivery pump 3, and the delivery pump 3 The suction port 3i is connected to the water outlet of the water storage tank 2 through a connection line 21 using a hose member. Reference numeral 4 denotes a pump drive unit that drives the delivery pump 3. In the illustrated example, the rotation of the engine 55 of the vehicle 50 is transmitted to the rotation input unit 3 d of the delivery pump 3 via the rotation transmission mechanism 22 and driven. Therefore, the engine 55 and the rotation transmission mechanism 22 constitute (also serve as) the pump drive unit 4.

  A water pressure adjusting unit 6 adjusts the water pressure of the cleaning water W fed by the water feeding hose unit 5 and includes a pressure adjusting cock 23, a pressure regulating valve 24, an electromagnetic valve 25, and a hydraulic pump 26 as shown in FIG. .

  In this case, the pressure regulating valve 24 includes a hydraulic cylinder portion 24c, and a valve portion 24v that changes the flow rate between the inlet port 24vi and the outlet port 24vo when the valve body is displaced by the hydraulic cylinder portion 24c. The inflow port 24vi is connected to the spillway 3r of the water pump 3 through a connection line 27 to which the pressure adjustment cock 23 is connected midway, and the outflow port 23vo is returned to the water storage tank 2 through the connection line 28. Connect to mouth.

  The pressure adjustment cock 23 can be effectively adjusted by the pressure regulating valve 24 by being set (switched) to the fully open position. In the present embodiment, the water pressure adjustment unit 6 is described for water pressure adjustment in the remote operation mode. However, the water pressure adjustment in the manual operation mode using a manual operation unit (not shown) provided in the control unit 42 described later. It is also used for purposes. The pressure adjustment cock 23 can be used as a preliminary adjustment means when control by the control unit 42 is impossible due to a failure or the like.

  The solenoid valve 25 is a four-port type, and one of the pair of output ports is connected to one connection port of the hydraulic cylinder portion 24 c via the connection line 30, and the other output port is connected to the hydraulic cylinder via the connection line 31. Connect to the other connection port of the part 24c. The discharge port 26 i of the hydraulic pump 26 is connected to one of a pair of input ports in the electromagnetic valve 25 via a connection line 32, and the return port 26 r of the hydraulic pump 26 is connected to the other of the input ports via a connection line 33. . The rotation of the engine 55 is transmitted to the rotation input unit 26d of the hydraulic pump 26 via the rotation transmission mechanism 34, thereby driving the hydraulic pump 26.

  On the other hand, the cleaning machine main body Mm includes the cleaning machine controller 41 shown in FIGS. 1 and 3. The washing machine controller 41 includes a control unit 42, and the control unit 42 includes a main body communication unit 9 that receives a stop command signal Cs transmitted from a smart phone H (mobile terminal Ms), which will be described later, and the main body communication. A stop control unit 10 that controls the pump drive unit 4 to stop based on the stop command signal Cs received by the unit 9 is provided. Therefore, the stop control signal Cx output from the stop control unit 10 is applied to the stop mode switch 43 shown in FIG.

  The stop mode switch 43 can be switched to the remote operation mode or the manual operation mode. The stop mode switch 43 is also provided with an emergency stop switch 43m. The emergency stop switch 43m can stop the engine 55 when pressed by an operator. The emergency stop switch 43m functions effectively both in the manual operation mode and the remote operation mode. 55c is a stop actuator. The stop actuator 55c only needs to have a function of stopping the engine 55, and may include, for example, an electromagnetic valve that cuts off the supply of gasoline fuel. Therefore, the pump drive unit 4 also stops when the engine 55 stops.

  The main body communication unit 9 has a reception function of receiving a water pressure adjustment signal Ch transmitted from a smart phone H, which will be described later. Further, the control unit 42 has a water pressure adjustment signal Ch received by the main body communication unit 9. Is provided with a water pressure control unit 15 that outputs a water pressure control signal Cy. This water pressure control signal Cy is applied to the water pressure adjusting unit 6, that is, the water pressure is adjusted by being applied to the control signal input port 25s of the electromagnetic valve 25 shown in FIG. As described above, the main body communication unit 9 is provided with a reception function for receiving the water pressure adjustment signal Ch, and the water pressure control unit 15 that controls the water pressure adjustment unit 6 based on the water pressure adjustment signal Ch received by the main body communication unit 9. If provided, the existing water pressure adjusting unit 6 can be used as it is, which can contribute to low cost and ease of implementation.

  In addition, the main body communication unit 9 includes two antennas 16a and 16b installed at different positions. As the different positions, the right side and the left side of the vehicle 50 described above can be selected. As an example, the installation position of the antenna 16a is shown in FIG. The antennas 16 a and 16 b are connected to the antenna port of the main body communication unit 9. Thus, if the main body communication unit 9 is provided with two antennas 16a and 16b installed at different positions, one antenna 16a (or 16b) is located in a place where the radio wave condition is poor (weak) or the like. Even if it exists, since it becomes communicable by the other antenna 16b (or 16a), the stability and reliability of the drainpipe washing | cleaning system 1 can be improved, for example, communication performance can be improved more.

  On the other hand, an example of the smart phone H used for the mobile terminal Ms is shown in FIG. The smart phone H includes a display 11 with a touch panel. Various terminals other than the smart phone H are known as the mobile terminal Ms. However, by using the smart phone H, it is not necessary to construct an individual system by a short-range communication method or the like. Can be implemented. In addition, since the major wireless communication means N is used, there is an advantage that it is possible to minimize the adverse effects such as communication failure caused by the washing place, and to construct a system with high reliability, stability and reliability. .

  In addition, software for realizing the drain pipe cleaning system 1 according to the present embodiment is installed in the smart phone H in advance. FIG. 2 shows an example of the home screen 71 displayed on the display 11 after installation. This software includes two application programs. The first application program executes the emergency stop mode, and the second application program executes the water pressure adjustment mode. Therefore, on the home screen 71, a stop icon 72 for executing the emergency stop mode and an adjustment icon 73 for executing the water pressure adjustment mode are displayed.

  Accordingly, the first application program that executes the emergency stop mode displays the stop screen 44 shown in FIG. 5 by touching (ON) the stop icon 72, and is turned on by touching the stop screen 44. A function of displaying a stop button 7 that can be switched to the side is provided. Thereby, the stop command signal Cs is output by switching the stop button 7 to the ON side. Furthermore, the mobile communication unit 8 is provided that can transmit the stop command signal Cs by the wireless communication means N. In this way, if the stop button 7 is displayed on the display 11 with the touch panel in the smart phone H, it can be easily implemented by installing the application program, and the use of the smart phone H that has portability and is easy to use. Thus, a quick and reliable operation can be performed.

  The second application program that executes the water pressure adjustment mode displays the adjustment screen 45 shown in FIG. 6 by touching (ON) the adjustment icon 73, and adjusts the water pressure on the adjustment screen 45. The function of displaying the adjustment operation part 12 for performing is provided. Further, the mobile communication unit 8 described above has a function of outputting a water pressure adjustment signal Ch based on this operation by the operation of the adjustment operation unit 12 and transmitting the water pressure adjustment signal Ch by the wireless communication means N. As shown in FIG. 6, the exemplary adjustment operation unit 12 includes a high pressure button 46 u and a low pressure button 46 d displayed on the adjustment screen 45. In this case, if the high pressure button 46u is touched, the water pressure can be increased only during the touch, and if the low pressure button 46d is touched, the water pressure can be decreased only during the touch. And since the magnitude | size of this water pressure is displayed on the water pressure level display part 46m on the adjustment screen 45, the operator can confirm the change state of water pressure visually.

  As described above, the smart phone H (mobile terminal Ms) is provided with the adjustment operation unit 12 for adjusting the water pressure, and the mobile communication unit 8 is supplied with the water pressure adjustment signal Ch based on the operation of the adjustment operation unit 12 by the wireless communication means N. If the transmission function to transmit is provided, the operator can quickly adjust the water pressure by the mobile terminal Ms carried. Thereby, the fluctuation | variation of the water pressure which generate | occur | produces in the drain pipe washing | cleaning work in upper floors and lower floors, such as a high-rise apartment house and an office building, can be suppressed easily. Therefore, it is possible to always ensure appropriate cleaning quality regardless of the cleaning location and height, and avoid problems such as unnecessary energy consumption.

  Furthermore, on the adjustment screen 45, a setting operation unit 13 capable of setting a variable amount with respect to the time related to the operation of the adjustment operation unit 12 is displayed. As illustrated in FIG. 6, the exemplary setting operation unit 13 includes a “+” button 47 u and a “−” button 47 d that are displayed on the adjustment screen 45 of the display 11. Accordingly, if the “+” button 47 u is touched, the time can be lengthened only during the touch, and if the “−” button 47 d is touched, the time can be shortened only during the touch. Since the length of this time is displayed on the time level display section 47m on the adjustment screen 45, the operator can visually confirm the time setting state. Note that setting a longer time means shifting to a constant water pressure over a long period of time, i.e., reducing the adjustment speed, and setting a shorter time means maintaining a constant water pressure over a short period of time. It means shifting, that is, the adjustment speed is increased. Reference numeral 48 denotes a reset button, which can be reset to the preset standard level by adjusting the water pressure adjustment level and the time setting level.

  As described above, if the setting operation unit 13 capable of setting a variable amount with respect to the time related to the operation of the adjustment operation unit 12 is provided, the target water pressure is adjusted faster or more accurately. It is possible to set the adjustment speed in consideration of the above. As a result, the setting according to the state of the washing place and the preference of the operator (operator) can be performed in a timely manner, so that the usability and convenience can be further improved.

  Next, the usage method and the whole function of the drain pipe cleaning system 1 according to the present embodiment will be described with reference to FIGS.

  FIG. 4 shows a case where, for example, the inside of the drain pipe P (see FIG. 9) installed in the high-rise apartment 100 is high-pressure washed with the washing water W using the washing machine main body Mm mounted on the vehicle 50. Yes.

  In this case, in the cleaning of the lower floors 101 of the first floor and the second floor, the water pressure does not become so high, so there is little possibility that a problem due to the high pressure occurs. Therefore, there is little need to use the drain pipe cleaning system 1 according to the present embodiment, and cleaning can be performed by normal cleaning, that is, manual operation mode.

  In the manual operation mode, the water pressure adjustment unit 6 can be controlled by manually operating a manual operation unit (not shown) provided in the control unit 42 in FIG. In this case, the water pressure by the water pressure adjusting unit 6 in the initial setting is set to about 20 [MPa] which is a standard water pressure, for example. Further, the pressure adjustment cock 23 is set to the fully open position by operating the operation lever 23h. The pressure adjustment cock 23 also functions as a preliminary adjustment means that allows the operator to vary the magnitude of the water pressure by manually operating the operation lever 23h when control by the control unit 42 is impossible due to failure or the like.

  Next, a remote operation mode that constitutes a characteristic part of the drain pipe cleaning system 1 according to the present embodiment will be described with reference to flowcharts shown in FIGS. 7 and 8.

  First, when using the remote operation mode, the stop mode switch 43 is switched to the remote operation mode side (steps S1 and S2). As a result, the control unit 42 can be controlled in the remote operation mode. Therefore, the water pressure control unit 15 of the control unit 42 sets the water pressure control signal Cy to be an initial position with respect to the control signal input port 25s of the electromagnetic valve 25, for example, about 20 [MPa] which is a standard water pressure. Is granted. In addition, a signal from the smart phone H can be received. If it is in this state, since it will be controlled so that it will become a standard water pressure, the washing | cleaning in the lower floor 101 shown in FIG. 4 can be performed similarly to the manual operation mode mentioned above.

  On the other hand, it is assumed that the cleaning floor is the middle floor 105. Since the operator can see the flow meter 62 as shown in FIG. 9 at the time of cleaning, if it is determined that the flow rate of the cleaning water W has decreased due to a decrease in the water pressure, the water pressure adjustment mode is used to adjust the water pressure. Adjustment processing can be performed (steps S3 and SB). That is, it is possible to adjust to increase the water pressure of the cleaning water W. On the other hand, when the lower floor 101 is washed again, the water pressure of the washing water W can be adjusted to be lowered.

  In this case, first, the worker prepares a smart phone H that is carried. Then, the adjustment icon 73 on the home screen 71 shown in FIG. 2 is touched (ON) (step S13). Thereby, the adjustment screen 45 shown in FIG. 6 is displayed (step S14). At this time, in order to increase the water pressure, the high pressure button 46u is touched (ON) (steps S15, S16, S17). Thereby, while the high pressure button 46u is touched, the water pressure adjustment signal Ch for increasing the water pressure is output and transmitted from the mobile communication unit 8 via the wireless communication means N, that is, transmitted from the smart phone H (step S1). S19). On the other hand, when lowering the water pressure, the low pressure button 46d is touched (ON) (steps S15, S16, S18). As a result, while the low pressure button 46d is being touched, a water pressure adjustment signal Ch for lowering the water pressure is output and transmitted from the mobile communication unit 8 via the wireless communication means N, that is, transmitted from the smart phone H (step S1). S19).

  On the other hand, the water pressure adjustment signal Ch is received by the main body communication unit 9 provided in the cleaning machine main body Mm through the antennas 16a and 16b (step S20). The received water pressure adjustment signal Ch is given to the water pressure control unit 15 and outputs a water pressure control signal Cy corresponding to the water pressure adjustment signal Ch. Moreover, this water pressure control signal Cy is given to the control signal input port 25s of the electromagnetic valve 25 shown in FIG. 3, and the adjustment process with respect to the water pressure adjustment part 6 is performed (step S21). Specifically, the solenoid valve 25 is controlled, and pressure oil is applied from the hydraulic pump 26 to the hydraulic cylinder 24c. At this time, in the case of the water pressure control signal Cy for increasing the water pressure, the valve portion 24v is controlled to close, and the flow rate to the water supply hose portion 5 is increased. This increases the water pressure. On the other hand, in the case of the water pressure control signal Cy for lowering the water pressure, the valve portion 24v is controlled to open and the flow rate to the water supply hose portion 5 is decreased. This lowers the water pressure. Since the degree of water pressure adjustment at this time is displayed by the water pressure level display unit 46m, the operator can visually grasp the water pressure level and whether or not the necessary water pressure is ensured is determined by the flow rate at hand. This can be confirmed by a total of 62.

  Furthermore, the adjustment speed can be set as necessary. In this case, the setting operation unit 13 is operated on the adjustment screen 45 (step S22). That is, in order to decrease the adjustment speed, the “+” button 47u is touched (ON) (steps S23 and S24). As a result, a time extension process is performed in which the time is increased only while the “+” button 47u is touched (step S25). On the other hand, to increase the adjustment speed, the "-" button 47d is touched (ON) (steps S23 and S26). As a result, a time shortening process is performed in which the time is shortened only while the “−” button 47d is touched (step S27). Since the setting degree at this time is displayed by the time level display part 47m, the operator can grasp | ascertain the setting level of time by visual observation.

  By the way, when the cleaning operation is performed on the upper floor 110 as shown in FIG. 2, the water pressure m when the water is supplied from the main body Mm of the cleaning machine is considerably high and the front side of the water supply hose portion 5 is increased. The distance between the operator who operates and the washing machine main body Mm also becomes considerably long. As a result, there is a high possibility that troubles such as the middle of the water supply hose part 5 rupturing or the coupler connecting the water supply hose part 5 may be disconnected. When such a trouble occurs, there is a problem that a corridor or a staircase in a house or building is submerged. In this case, it is necessary to immediately stop water supply.

  Assume that a trouble occurs in which the middle of the water supply hose portion 5 bursts. In this case, water discharge trouble processing can be performed using the emergency stop mode (steps S3 and SA). The operator can confirm that a trouble has occurred because the momentum of the cleaning water W discharged from the cleaning nozzle 5n suddenly weakens or the flow rate displayed by the flow meter 62 decreases rapidly. The stop icon 72 on the home screen 71 of the smart phone H of FIG. 2 is touched (ON) (step S4). Accordingly, since the stop screen 44 shown in FIG. 5 is displayed, the operator immediately touches (ON) the stop button 7 (steps S5 and S6).

  When the stop button 7 is touched, a stop command signal Cs is output, and the stop command signal Cs is transmitted from the mobile communication unit 8 via the wireless communication means N, that is, transmitted from the smart phone H (step S7). On the other hand, the stop command signal Cs is received by the main body communication unit 9 through the antennas 16a provided in the cleaning machine main body Mm (step S8). As a result, the received stop command signal Cs is given to the stop control unit 10, and a stop control signal Cx corresponding to the stop command signal Cs is output from the stop control unit 10 (step S9). The stop control signal Cx is applied to the engine stop switch 43, and the engine stop switch 43 is switched to perform a stop process on the engine 55 (step S10). Thereby, the water supply pump 3 also stops and water supply stops.

  The operator confirms the trouble and performs trouble-solving processing to replace the trouble part (such as the hose body 5m) if necessary (step S11). When the trouble solving process is completed, the stop button 7 is reset by pressing the reset button 48, and the engine 55 can be started (step S12). Thereby, the cleaning operation can be continued.

  Therefore, according to such a drain pipe cleaning system 1 according to this embodiment, as a basic configuration, a water storage tank 2 that stores the cleaning water W, a delivery pump 3 that sends the cleaning water W of the water storage tank 2, and A pump drive unit 4 that drives the delivery pump 3, a water supply hose unit 5 that feeds the washing water W delivered by the delivery pump 3, and has a washing nozzle 5 n that can be inserted into the drain pipe P at the distal end, A washing machine main body Mm having a water pressure adjusting unit 6 for adjusting the water pressure of the washing water W fed by the water feeding hose unit 5 is provided. In particular, as a characteristic configuration, a stop button 7 that can be switched to the ON side and the stop button 7 includes a mobile terminal Ms having at least a mobile communication unit 8 capable of transmitting by a wireless communication means N a stop command signal Cs output by switching to the ON side. The machine main body Mm is provided with at least a main body communication unit 9 that receives a stop command signal Cs and a stop control unit 10 that controls the pump drive unit 4 based on the stop command signal Cs received by the main body communication unit 9. Therefore, even in the case where a trouble such as the middle of the water supply hose part 5 rupturing or the coupler connecting the water supply hose part 5 is disconnected in a drain pipe cleaning operation in a high-rise apartment or office building, An operator at the front end side of the water supply hose unit 5 can catch the occurrence of trouble due to a decrease in water pressure or a decrease in the amount of water, and can quickly stop water supply. As a result, it is possible to minimize the problem that the corridors, stairs, etc. in the house or building are flooded, and it is also possible to avoid the generation of extra costs such as arranging a supervisor.

  In addition, in FIG. 10, the example of a change of the drain pipe cleaning system 1 which concerns on this embodiment is shown. The drainpipe cleaning system 1 according to this modified example is configured such that the control unit 42 provided in the cleaning machine main body Mm and the smart phone H are capable of bidirectional communication. A small camera 82 for photographing the water pressure gauge (or flow meter) 83 in the washing machine main body Mm is installed on the washing machine main body Mm side, and a video image taken by the camera 82 is sent from the control unit 42 to the smartphone. To H. On the other hand, in the smart phone H, an image display unit 81 is provided in a part of the adjustment screen 45, and the received video image can be displayed on the image display unit 81. Thereby, the operator can confirm the water pressure display of the water pressure gauge 83 provided in the washing machine main body Mm by the water pressure gauge image 83p displayed on the smart phone H. Therefore, the operator can adjust the water pressure while viewing the water pressure gauge image 83p. The illustration shows a case where the water pressure gauge 83 is photographed, but the entire operation panel, display panel, etc. of the washing machine main body Mm may be photographed, and this makes it easy and easy even if the state of the washing machine main body Mm is separated. It can be confirmed reliably.

  The preferred embodiments including the modified examples have been described in detail above, but the present invention is not limited to such embodiments, and the present invention is not limited to the detailed configuration, shape, method, quantity, numerical value, and the like. Changes, additions and deletions can be made arbitrarily without departing from the scope.

  For example, the case where the washing machine main body Mm in the drain pipe cleaning system 1 is mounted on the automobile 50 is shown, but it does not exclude the case where the washing machine main body Mm is not mounted on the automobile 50, such as a self-propelled washing machine main body Mm. . Moreover, although the case where the smart phone H is used as the mobile terminal Ms has been described, a mobile phone, a PDA (personal digital assistant), or the like may be used. In the case of a cellular phone, the function of the stop button 7 and the function of the adjustment operation unit 12 can be provided by transmitting a preset number or by continuously pressing the preset number. The adjustment operation unit 12 and the setting operation unit 13 are not essential elements, and can be provided as necessary. Furthermore, although the case where two antennas 16a and 16b are used is illustrated, the case where one or three or more antennas 16a... Are used is not excluded.
