Therefore, the blower 20, the side blowing nozzle 22, and the top blowing nozzle 21 constitute a drying unit that dries the vehicle to be cleaned CA by blowing.

  The remote panel 40 (operation unit) is arranged on the approach path S of the car wash machine body 1. The vehicle to be cleaned CA stops in front of the remote panel 40, and the user sets car wash conditions by operating the remote panel 40 from within the vehicle to be cleaned CA. As the setting of the car wash conditions, car wash conditions such as a car wash using only clean water, a car wash using a liquid agent such as waxing or a water repellent coating can be set.

  The remote panel 40 has a display unit 41 that displays an operation screen. The display unit 41 is formed by a liquid crystal panel having a touch panel on the front surface. On the display unit 41, an important area selection screen 46 (see FIG. 3) for selecting an area to be cleaned is displayed by a predetermined operation.

  FIG. 3 shows a front view of the priority area selection screen 46. On the priority area selection screen 46, vehicle images CB1 to CB3 are displayed corresponding to the shape of the vehicle to be cleaned CA. The vehicle image CB1 is a sedan type washed vehicle CA, the vehicle image CB2 is a 1BOX type washed vehicle CA, and the vehicle image CB3 is a minivan type washed vehicle CA.

  Predetermined messages 44 and 45 are displayed above the vehicle images CB1 to CB3. The message 44 displays “Are there any parts that are particularly worried about dirt?” So that the user can easily understand that the priority area selection screen 46 is being displayed. The message 45 will indicate "Washing the designated part (important area) carefully. You can specify up to 2 places", so you can select 2 places in the important areas S1 to S7. You can easily find out. Further, the “maximum two places” of the message 45 can be changed by the car wash staff, and may be set to a maximum of three places when the car wash machine WA is relatively free, such as on a weekday night.

  On each vehicle image CB1 to CB3, icons indicating a plurality of preferential areas S1 to S7 are displayed. Each icon of the priority areas S1 to S7 is formed in, for example, a white rectangle, and changes color when it is selected when pressed. In this embodiment, a maximum of two priority areas S1 to S7 can be selected.

  The priority area S1 is set on the front surface CA1 of the vehicle to be cleaned CA. When the priority area S1 is selected, the number of reciprocations of the side brush 5 that cleans the front surface CA1 increases from one to two from the non-selection.

  On the upper surface of the to-be-cleaned vehicle CA, priority areas S2 to S5 are set in a bonnet CA2, a windshield CA3, a roof CA4, and a rear glass CA5, respectively. When the priority areas S2 to S5 are selected, the moving speed of the car wash machine body 1 that passes through the priority areas S2 to S5 is slower than that in the case of non-selection.

  A priority area S6 and a priority area S7 are set on the back surface CA6 of the vehicle to be cleaned CA. The priority area S7 is provided when the vehicle to be cleaned CA is a sedan type, and the priority area S6 is set in the upper part of the back surface CA6 and the priority area S7 is set in the lower part. When the priority areas S6 and S7 are selected, the number of reciprocations of the side brush 5 that cleans the back surface CA6 increases from once to twice from the non-selected state.

  The operation button 42 is arranged below the vehicle image CB2, and is used when correcting the selected priority areas S1 to S7. By pressing the operation button 42, the selected priority areas S1 to S7 can be canceled by pressing the selected priority areas S1 to S7 again. The operation button 43 is arranged below the operation button 42, and is used when the priority area selection screen 46 is finished and a transition is made to the next car wash determination screen (not shown).

  In the car wash machine WA having the above configuration, the user drives to stop the vehicle CA to be cleaned in front of the remote panel 40. Next, a fee is charged into a fee input unit (not shown) provided in the remote panel 40, and the setting of the car wash condition for the vehicle to be cleaned CA is performed from within the vehicle to be cleaned CA.

  At this time, an important area selection screen 46 is displayed as shown in FIG. 3, and important areas S1 to S7 are selected as necessary. For example, when a minivan type user wants to cleanly clean the two areas of the front surface CA1 and the roof CA4 of the vehicle CA to be cleaned, the user presses the priority areas S1 and S4 of the vehicle image CB3. The following car wash operation will be described by taking as an example the case where the priority areas S1 and S4 are selected.

  When the cleaning condition is set, the user moves the vehicle to be cleaned CA to a predetermined cleaning start position. When the car wash machine WA detects that the car to be washed CA has moved to the washing start position, the car wash machine body 1 moves toward the rear of the car to be washed CA. Then, the cleaning process is started, and cleaning is performed based on the shape of the vehicle CA to be cleaned detected by the shape sensor 9.

  When the cleaning process is started, city water is jetted from the first, second, and third water purification nozzles 11, 13, and 17, and the vehicle to be cleaned CA is cleaned by the top brush 4 and the side brush 5. When the side brush 5 reaches the front surface CA1 of the vehicle to be cleaned CA, the movement of the car wash machine body 1 temporarily stops. Then, the side brush 5 reciprocates in the left-right direction to clean the front surface CA1 of the vehicle CA to be cleaned. At this time, since the priority area S1 is selected, the side brush 5 reciprocates twice.

  When the side brush 5 finishes cleaning the front surface CA1 of the vehicle CA to be cleaned, the car wash machine body 1 resumes moving. Then, the upper surface of the vehicle CA to be cleaned is cleaned with the top brush 4, and the side surface of the vehicle CA to be cleaned is cleaned with the side brush 5. At this time, since the priority area S4 is selected, the moving speed of the car wash machine body 1 while the top brush 4 is disposed on the roof CA4 is slower than when the priority area S4 is not selected. As a result, the cleaning time for the roof CA4 becomes longer and the cleaning power can be increased.

  Moreover, you may make the water pressure of the 3rd water purification nozzle 17 larger at the time of washing | cleaning of important area | region S4 than the case where important area S4 is not selected. Thereby, the cleaning power can be further increased with respect to the roof CA4.

  When the side brush 5 reaches the rear surface CA6 of the vehicle CA to be cleaned, the movement of the car wash machine body 1 temporarily stops. Then, the side brush 5 reciprocates once in the left-right direction to clean the vehicle to be cleaned CA, and the cleaning process ends.

  Thereafter, the car wash machine main body 1 is reversed and moves toward the front of the vehicle to be cleaned CA, and air is blown from the top blow nozzle 21 and the side blow nozzle 22 to start the drying process. At this time, the moving speed of the car wash machine body 1 is faster than when all the priority areas S1 to S7 are not selected. For this reason, the time of the drying process when the priority areas S1 and S4 are selected is shorter than when all the priority areas S1 to S7 are not selected.

  Thereafter, when the user confirms that the movement of the car wash machine main body 1 is stopped and the drying process is finished, the car to be washed CA is moved from the exit side of the car wash machine main body 1 and the car wash is finished.

  According to the present embodiment, desired priority areas S1 to S7 can be selected from a plurality of preset priority areas S1 to S7 by the remote panel 40 (operation unit). And the cleaning power of the top brush 4 and the side brush 5 with respect to priority area | region S1-S7 selected by the remote panel 40 was made higher than the case of non-selection. Therefore, it is possible to improve the cleaning power of the priority areas S1 to S7 desired by the user, eliminate the unwashed residue, and improve the convenience of the car wash machine WA.

  In addition, when the focus areas S2 to S5 (the focus area S4 in the above example) selected by the remote panel 40 are cleaned by the top brush 4, the moving speed of the car wash machine body 1 is made slower than that in the case of non-selection. As a result, the selected priority areas S2 to S5 can be cleaned over time, and the cleaning power can be easily increased.

  Further, when the priority areas S1, S6, and S7 (the priority area S1 in the above example) provided on the front surface CA1 or the rear surface CA6 of the vehicle to be cleaned CA are selected, the number of reciprocations of the side brush 5 is larger than that in the case of non-selection. increase. Thereby, it is possible to easily increase the cleaning power for the selected priority areas S1, S6, and S7. Note that the lateral movement speed of the side brush 5 with respect to the selected priority areas S1 and S6 may be slower than when the selection is not performed.

  Moreover, the time of the drying process when any of the priority areas S1 to S7 is selected is shorter than when all the priority areas S1 to S7 are not selected. Thereby, even if the time of the washing process is increased, the time of the drying process is shortened, so that the time of the entire car wash can be prevented from increasing and the congestion of the car wash machine WA can be prevented.

  Moreover, the water pressure of the 3rd water purification nozzle 17 was enlarged rather than the case of non-selection, when the important area | region S1-S7 selected by the remote panel 40 was wash | cleaned by the 3rd water purification nozzle 17. FIG. Thereby, the cleaning power of the selected priority areas S1 to S7 can be further increased.

  In this embodiment, the cleaning process time when at least one priority area (for example, the priority area S1) is selected and the cleaning process time when all the priority areas S1 to S are not selected are substantially the same. Also good. That is, the cleaning time for the non-selected priority areas S2 to S7 when the priority area S1 is selected is shorter than the cleaning time for the priority areas S2 to S7 when all the priority areas S1 to S7 are not selected. As a result, it is possible to prevent an increase in time of the cleaning process and to prevent congestion when using the car wash machine WA. In this case, you may make the time of the drying process at the time of selecting important region S1-S7 and the time of the drying process at the time of non-selecting important region S1-S7.

Second Embodiment
This embodiment is different from the first embodiment in the cleaning method of the priority areas S1 to S7 with respect to the first embodiment. Other parts are the same as those in the first embodiment.

  For example, when the user selects the priority areas S1 and S4 with the remote panel 40, the rotational speed or pressing force of the rotating brush is set larger than when the priority areas S1 and S4 are cleaned. At this time, the water pressure of the third water purification nozzle 17 may be set larger than when the non-selection is performed during the cleaning of the priority areas S1 and S4. Thereby, it is possible to increase the cleaning power for the selected priority areas S1 and S4 without increasing the time of the cleaning process.

  It should be noted that the rotational speed or pressing force of the rotating brush may be the same as that in the non-selection for the priority areas S3 and S5 on the windshield CA3 and the rear glass CA5. Thereby, breakage of windshield CA3 and rear glass CA5 can be prevented. At this time, the cleaning power can be increased by increasing the water pressure of the third water purification nozzle 17 with respect to the priority areas S3 and S5 as compared with the case where the water pressure is not selected.

  According to the present embodiment, as in the first embodiment, the cleaning power of the top brush 4 and the side brush 5 with respect to the priority areas S1 to S7 selected by the remote panel 40 is made higher than that in the case of non-selection. Therefore, it is possible to improve the cleaning power of the priority areas S1 to S7 desired by the user, eliminate the unwashed residue, and improve the convenience of the car wash machine WA.

  Further, when cleaning the priority areas S <b> 1 to S <b> 7 selected by the remote panel 40, the rotational speed or pressing force of the rotating brush (top brush 4, side brush 5) was increased as compared with the case of non-selection. Thereby, it is possible to easily increase the cleaning power for the selected priority areas S1 to S7 without increasing the time of the cleaning process.

  Moreover, the water pressure of the 3rd water purification nozzle 17 was enlarged rather than the case of non-selection, when the important area | region S1-S7 selected by the remote panel 40 was wash | cleaned by the 3rd water purification nozzle 17. FIG. Thereby, the cleaning power of the selected priority areas S1 to S7 can be further increased.

  As in the present embodiment, in the first embodiment, the rotation speed or the pressing force of the rotating brush may be set larger during the cleaning of the priority areas S1 to S7 than when it is not selected.

  Further, the remote panel 40 may be provided with a reading unit that reads a receipt storing the types of the vehicle images CB1 to CB3 at the previous use. At this time, when the receipt is read by the remote panel 40, the vehicle images CB1 to CB3 previously selected on the priority area selection screen 46 may blink to make them stand out from the other vehicle images CB1 to CB3.
