As a result, the first washing water W1 and the second washing water W2 can be evenly sprayed onto the plurality of bottles G stored in the rack 50 .

(Common piping)
As shown in FIGS. 9 and 10, the common pipe 51 is formed in a comb-teeth shape when viewed from above while bending and branching in a substantially horizontal direction, and is provided to extend upward from the common pipe 51. A plurality of nozzles 52 are fixed to the bottom of the rack 50 so as to be arranged substantially in the center of each storage space 50a when viewed from the top, forming a continuous conduit from one end to the other end.

A first inlet (inlet) 53 into which the first washing water W1 flows is provided at one end of the shared pipe 51 . A first connection pipe (connection pipe) 62 connected to a connection portion 60, which will be described later, is connected to the first inlet 53 via a first check valve (check valve) 53a. The first check valve 53 a is attached so that the wash water in the shared pipe 51 does not flow back from the shared pipe 51 to the first connection pipe 62 .

A second inlet (inlet) 55 is provided on the other end side of the shared pipe 51 to allow the second washing water W2 to flow thereinto. A second connection pipe (connection pipe) 64 connected to the connection portion 60 is connected to the second inlet 55 via a second check valve (check valve) 55a. The second check valve 55 a is attached so that the wash water in the shared pipe 51 does not flow back from the shared pipe 51 to the second connection pipe 64 . By configuring the common pipe 51 in this manner, the following flow paths are formed.

As shown in FIG. 11, when the first wash water W1 flows in from the first inlet 53, the second check valve 55a is closed, so the end of the common pipe 51 is blocked. A first flow path (flow path) 54 that is one continuous flow path is formed.

Conversely, as shown in FIG. 12, when the second wash water W2 flows in from the second inlet 55, the first check valve 53a is closed, so the common pipe 51 is A second channel (channel) 56, which is a single continuous channel with a closed end, is formed.

Further, when the wash water does not flow into the common pipe 51 from any of the inlets 53, 55, that is, when both of the wash water supply means 13, 23 are stopped, the discharge pressure from the wash water supply means 13, 23 is When the pressure is not applied, both the first check valve 53a and the second check valve 55a are in a closed state, so that the last wash water that has flowed into the common pipe 51 can be stored.

This prevents the wash water in the shared pipe 51 from flowing back from the inlets 53 and 55 and mixing different wash water in the wash water supply means 13 and 23 and the tanks 10 and 20. Wash water can be stored.

In addition, since the positions of the first inlet 53 and the second inlet 55 are different in the shared pipe 51, the first flow path 54 and the second flow path 56 have the same configuration. The pipe line length (channel length) from 55 to each nozzle 52 is different.

For example, among the plurality of nozzles 52 of the rack 50, the nozzle 52 at the position with the shortest flow path length from the first inlet 53 (the nozzle 52 closest to the first inlet 53) is X The first nozzle (nozzle) 52X is the position, and Y A case will be described where the position is the second nozzle (nozzle) 52Y.

As shown in FIG. 11, in the first flow path 54, the flow path length from the first inlet 53 to the first nozzle 52X at the X position is longer than the flow path length from the first inlet 53 to the first nozzle 52X at the X position. 2 nozzle 52Y becomes long. That is, the second nozzle 52Y at the Y position is farther than the first nozzle 52X at the X position, which is closest to the first inlet 53, with respect to the first inlet 53. in position.

In addition, as shown in FIG. 12, in the second flow path 56, the distance from the second inlet 55 to the X position is longer than the flow path length from the second inlet 55 to the second nozzle 52Y at the Y position. , the length of the flow path to the first nozzle 52X becomes longer. That is, the first nozzle 52X at the X position is farther than the second nozzle 52Y at the Y position, which is closest to the second inlet 55, with respect to the second inlet 55. in position. In this way, by providing the inlets 53 and 55 at different locations in the shared pipe 51, the lengths of the flow paths to the respective nozzles 52 with the inlets 53 and 55 as a reference are configured to be different.

The plurality of nozzles 52 are such that the first flow path 54 and the second flow path 56 have the same flow path length from the first inlet 53 and the second inlet 55. It may be included, and at least two or more nozzles 52 may be configured to have different channel lengths.

Further, the positions of the first inlet 53 and the second inlet 55 are not limited to the one end side and the other end side of the common pipe 51, and may be different positions. However, as will be described later, for example, when comparing the total amount of washing water W1 and W2 jetted from the first nozzle 52X at the X position and the second nozzle 52Y at the Y position, the first flow path 54 The positions of the first inflow port 53 and the second inflow port 55 can be mutually changed so that the total amount of the washing water W1 and W2 to be jetted is substantially opposite between the and the second flow path 56. It is preferable to provide them at one end side and the other end side of the common pipe 51, which are as far apart as possible (distant positions).

As shown in FIGS. 2 and 10, the common pipe 51 is provided with a plurality of nozzles 52 directed upward for injecting the washing water W1 and W2 flowing in the common pipe 51 .

The nozzle 52 is a hollow pipe formed with a predetermined length, has an injection port 52a on the upper surface of the upper end, and has a hole provided in the upper part of the common pipe 51 formed in the horizontal direction at the lower end. , and the inside of the nozzle 52 and the inside of the shared pipe 51 are configured to communicate with each other. As a result, the washing water W1, W2 flowing in the shared pipe 51 flows upward in the nozzle 52 and can be jetted upward from the jet port 52a.

The plurality of nozzles 52 provided in the common pipe 51 are arranged on the common pipe 51 so that when the common pipe 51 is arranged at the bottom of the rack 50, they are arranged substantially in the center of the storage space 50a of the rack 50 in a top view. installed.

The length and inner diameter of the nozzle 52 and the diameter of the injection port 52a are substantially the same in the plurality of nozzles 52. As shown in FIG.

As shown in FIGS. 2 and 13, an annular spacer 57 made of resin or the like is provided near the base of the nozzle 52 provided in the common pipe 51 (near the joint between the common pipe 51 and the nozzle 52). When the bottle G is stored in the storage space 50a of the rack 50 by inserting the nozzle 52 into the inside of the bottle G from the opening G1 in an inverted posture with the opening G1 of the bottle G facing downward. Then, the opening G1 of the bottle G is placed on the upper surface of the spacer 57. As shown in FIG. As a result, it is possible to prevent the bottle G, which is made of glass or the like, from being damaged due to vibration or the like caused by the injection of the cleaning water.

The spacer 57 is provided with a notch portion 57a that penetrates the spacer 57 in the vertical direction. can flow out through the notch 57a. Note that the notch 57a does not have to penetrate the spacer 57 in the vertical direction. If the wash water in the bottle G can flow out, the notch 57a is provided from the top surface to the side surface, for example. Anything is fine. The amount of wash water that flows out from the opening G1 of the bottle G per unit time can be adjusted by the size of the area of the notch 57a.

The shape of the spacer 57 is not limited to an annular shape, and may be other shapes such as a rectangular shape. Further, the shape including the notch portion 57a is not limited to the C shape when viewed from the top, and may be other shapes such as a polygonal shape when viewed from the top or a petal shape. In this case, it is preferable to set the size and shape of the opening of the notch 57a while maintaining a state in which the opening G1 of the bottle G can be placed stably.

Further, by changing the thickness of the spacer 57, the position of the bottle G in the height direction with respect to the position of the injection port 52a of the nozzle 52 can be changed. For example, when washing bottles G having different height positions of the necks G4 of the bottles G, such as storing a plurality of bottles G with different shapes together in the rack 50 and washing them, spacers 57 with different thicknesses can be used. Without changing the height of the nozzle 52, the height position of the shoulder G3 of the bottle G with respect to the injection port 52a can be adjusted to a desired position.

As a result, when the cleansing water jetted into the inside of the bottle G temporarily stays near the neck G4 before flowing out from the notch 57a, the jet port 52a is submerged in the stagnant cleansing water. It is possible to prevent the wash water jetted from the port 52a from not being jetted to a desired position inside the bottle G.

In addition, for example, when it is desired to intensively inject the cleaning water toward the bottom surface of the bottle G where dirt is likely to accumulate, the position of the injection port 52a is brought closer to the bottom surface of the bottle G so that the cleaning water can be sprayed onto the bottom surface of the bottle G. The thickness of the spacer 57 may be changed to adjust the position of the bottle G in the height direction with respect to the injection port 52a so as to make good contact with the . As a result, optimal cleaning can be performed according to the shape of the bottle G and the location where dirt is accumulated.

The shape (pipe layout) of the shared pipe 51 is an example, and any shape of the pipe may be used as long as the plurality of nozzles 52 can be arranged in each storage space 50a. For example, the shape of the shared pipe may be a substantially rectangular loop pipe having no ends when viewed from the top. Also in this case, the positions of the first inlet 53 and the second inlet 55 need only be provided at different positions of the loop pipe, and the positions are separated from each other as much as possible, for example, on the upper surface. It is preferable to provide it in a diagonal position or an opposite side position visually.

The door sensor 4b detects that the door portion 4 is closed and sends a signal to the control portion 6. FIG. The control unit 6 opens the solenoid valve 28 a provided in the water supply pipe 28 to start supplying fresh water, which is the second wash water W<b>2 , from the water supply pipe 28 to the second tank 20 .

When the second wash water W2 is full, the upper limit water level sensor 27a and the lower limit water level sensor 27b detect the full level and send a signal to the control section 6. FIG. The control unit 6 closes the solenoid valve 28a of the water supply pipe 28 to stop the supply of clean water, operates the second heating means 21, and starts heating the second wash water W2. A second temperature sensor 22 detects that the second wash water W2 stored in the second tank 20 has reached a predetermined temperature, for example, 80° C., and sends a signal to the controller 6. The controller 6 stops the second heating means 21 .

Next, as shown in FIG. 19, the control section 6 drives the second washing water supply means 23 . Then, the second washing water W2 flows through the second washing water flow system 72 and enters the washing chamber 30 from the second washing nozzle 43 of the rotating nozzle 40 and the nozzle 52 of the rack 50 for a predetermined time. For example, it is jetted for 12 seconds.

Specifically, the second washing water W2 sucked from the second tank 20 by the second washing water supply means 23 and discharged to the second washing pipe 24 is supplied from the second washing pipe 24 to the top connection. It branches into the opening 32 and the lower connecting opening 35 and flows into the respective second flow paths 34a, 37a.

When the amount of the second wash water W2 stored in the second tank 20 decreases and the upper limit water level sensor 27a detects that the water level is not full, a signal is sent to the control unit 6. The controller 6 opens the solenoid valve 28a of the water supply pipe 28 to supply fresh water to the second tank 20 until the upper limit water level sensor 27a detects that the water is full. At this time, the controller 6 continues heating by the second heating means 21 only when the lower limit water level sensor 27b does not detect that the water level of the second wash water W2 is lower than the lower limit water level. .

When the controller 6 detects that the second tank 20 is full of the second wash water W2, it closes the solenoid valve 28a of the water supply pipe 28 to stop the water supply. When the second temperature sensor 22 detects that the second wash water W2 stored in the second tank 20 has reached a predetermined temperature, for example, 80° C., the controller 6 activates the second heating means 21 to stop Then, the second washing water supply means 23 is driven to inject the second washing water W2 from the rotary nozzle 40 and the nozzle 52 of the rack 50 and store the water in the first tank 10 . This is repeated until the first tank 10 is filled with water to a full water level.

When the first tank 10 is full of the second wash water W2, the upper limit water level sensor 17a detects that the water is full and sends a signal to the controller 6. FIG. The controller 6 stops driving the second cleaning water supply means 23 .

At this time, both the first check valve 53a and the second check valve 55a are closed, so that the shared pipe 51 is in a state where the second wash water W2 is stored.

The control unit 6 monitors the temperature of the wash water stored by the first temperature sensor 12 of the first tank 10, and when the temperature drops below a predetermined temperature, the first heating means 11 is appropriately operated to Control to maintain temperature. This continues until the first cleaning step S3 is started.

Then, when the control unit 6 detects that the temperature of the second wash water W2 stored in the second tank 20 to the full water level has reached a predetermined temperature by means of the second temperature sensor 22, , the second heating means 21 is stopped. Further, the control unit 6 monitors the temperature of the second wash water W2 stored by the second temperature sensor 22, and when the temperature drops below a predetermined temperature, the control unit 6 appropriately operates the second heating means 21 to Control to maintain temperature. This continues until the second cleaning step S4 is started.

In addition, the detergent supplying means (not shown) is driven to supply the detergent to the first tank 10 so as to have a predetermined concentration. It becomes the first washing water W1 containing

As shown in FIG. 20, the control unit 6 detects that the cleaning water in the first tank 10 and the second tank 20 both have a predetermined temperature and are full, and performs cleaning steps S3 and S4. A buzzer (not shown) provided in the operation unit 7 is sounded to inform the operator that preparation for performing the operation is completed, and the preparation step S1 ends.

At this time, the first connection pipe 62 and the second connection pipe 64 are deformed so as to follow the movement of the rack 50, and the connection portion 60 rotates with respect to the lower connection opening 35, thereby smoothly moving. can do.

Then, the bottle G is stored in the storage space 50a of the rack 50 in an inverted posture with the opening G1 facing downward. At this time, the bottle G is housed so that the opening G1 of the bottle G is inserted into the nozzle 52 of the rack 50, and the bottle G is housed so that the opening G1 of the bottle G is placed on the upper surface of the spacer 57. FIG.

After storing a plurality of bottles G in the rack 50, the rack 50 is held and pushed by hand, and carried from the rack standby position to the predetermined position of the rack support part 31. - 特許庁At this time, the first connection pipe 62 and the second connection pipe 64 are deformed so as to follow the movement of the rack 50, and the connection portion 60 rotates with respect to the lower connection opening 35, thereby smoothly carrying in the rack. can do. When the rack 50 has been carried into the predetermined position, the door portion 4 is closed, and the carrying-in step S2 ends.

(First washing step)
After the carrying-in step S2, the cleaning operation start switch (not shown) of the operation unit 7 is operated to start the first cleaning step S3. Upon receiving the signal from the operation unit 7 , the control unit 6 detects that the door unit 4 is closed by the door sensor 4 b and starts driving the first washing water supply means 13 . When the first cleansing water supply means 13 is driven, it flows through the first cleansing water flow system 71, and the first cleansing water W1 is jetted from the rotating nozzle 40 and the nozzle 52 of the rack 50 to clean the bottle G. .

As shown in FIG. 21 , the first washing water supply means 13 sucks the first washing water W1 from the first tank 10 and discharges it to the first washing pipe 14 . The first washing water W1 discharged to the first washing pipe 14 branches from the first washing pipe 14 to the upper connection opening 32 and the lower connection opening 35, and flows through the respective first flow paths 33a and 33a. Flow to 36a.

The first washing water W1 flowing into the upper connection opening 32 flows into the first washing nozzle 41 of the rotary nozzle 40 through the first joint portion 42, and flows downward from the injection port 41a for a predetermined time. , for example, for 75 seconds. The first washing water W1 that has come into contact with the bottle G washes away the contaminants adhering to the outer surface of the bottle G. Then, the first washing water W1 containing the dirt component flows down to the partition member 38 in the lower part of the washing chamber 30. As shown in FIG.

The first wash water W1 that has flowed to the lower connection opening 35 flows through the first joint portion 61 of the connection portion 60, flows to the first connection pipe 62, and passes through the first check valve 53a. It flows into the shared pipe 51 from the first inlet 53 . At this time, the second check valve 55a is closed.

The first wash water W1 that has flowed into the common pipe 51 flows through the first flow path 54 in the common pipe 51 and is jetted upward from the jet ports 52a of the nozzles 52, respectively.

At this time, since the shared pipe 51 is filled with the second wash water W2 stored in the preparation step S1, it is pushed out by the first wash water W1, and the second wash water W1 is pushed out before the first wash water W1. 2 of washing water W2 is injected into the bottle G for a predetermined time.

As a result, the inside of the bottle G can be washed by injecting the second washing water W2 after the first washing water supply means 13 is driven and before the first washing water W1 is injected from each nozzle 52. can be done. In particular, since the temperature of the second washing water W2 stored in the shared pipe 51 in the preparation step S1 is higher than that of the first washing water W1, for example, the preparation step S1 and the first washing step S3 are performed. If the temperature drop is suppressed as much as possible until the first cleaning step S3 is started, the second cleaning water W2 having a temperature higher than that of the first cleaning water W1 can be used. , can be injected into the bottle G.

For example, in the case where the contaminants inside the bottle G are sugars contained in beverages or fats and oils contained in seasonings, etc., the contaminants are heated to increase fluidity, and then the first cleaning is performed. It can be washed with water W1. In other words, the removal of the contaminants by the first washing water W1 can be promoted by the second washing water W2.

As a result, the second washing water W2, which has a higher temperature than the first washing water W1, heats the bottles G, which are the objects to be washed, and the dirt components adhering to the bottles G in advance, thereby increasing the fluidity of the dirt components. can increase Further, the removal of contaminants by the first washing water W1 can be accelerated, and the washability of the bottle G can be improved.

Further, since the temperature of the bottle G itself can be raised by the second washing water W2 stored in the shared pipe 51, the first washing water W1 injected after the second washing water W2 is The temperature of the first wash water W1 stored in the first tank 10 is prevented from dropping from the predetermined temperature by suppressing the temperature drop due to the contact with the bottle G, and the temperature of the first wash water W1 is kept at the predetermined temperature. can reduce the energy for reheating.

In addition to the first washing water W1 injected into the bottle G from the nozzle 52 of the rack 50, the first washing water W1 is also injected from the first washing nozzle 41 of the rotating nozzle 40, The outer surface is cleaned. At this time, the first cleaning water W1 jetted from the first cleaning nozzle 41 cleans the outer surface of the bottle G and raises the temperature of the bottle G. As shown in FIG. Therefore, the heat generated by the first washing water W1 sprayed from the first washing nozzle 41 acts on the dirt components adhering to the inner surface of the bottle G in addition to the dirt components adhering to the outer surface of the bottle G. become. In addition, when the dirt component adhering to the bottle G is saccharides or oils, the fluidity of the dirt component is enhanced, making it easier to wash off.

As a result, more washing water can be sprayed onto the bottle G, which is an object to be washed, to improve the detergency of the bottle G, and the temperature of the bottle G can be raised to make it easier to remove stains adhered to the bottle G.例文帳に追加

Further, since the shared pipe 51 is filled with the second wash water W2 stored in the preparation step S1, the second wash water W2 stored in the shared pipe 51 is removed in the first washing step S3. The first cleaning step S3 can be started quickly while reducing the amount of the first cleaning water W1 flowing in from the first inlet 53 by the same amount.

In addition, there is no need to set the driving time of the first washing water supply means 13 to include the time (time lag) from the time when the common pipe 51 is filled with the washing water to the time when the washing water is jetted from the plurality of nozzles 52. The cleaning time for the bottle G, which is the object to be cleaned, can be shortened as much as possible, and the energy required to inject the cleaning water W1 and W2 can be reduced.

Further, the cleaning water W1, W2 can be jetted for a longer period of time from the start to the end of the first cleaning step S3, which is performed for a predetermined period of time, and the bottle G to be cleaned in the first cleaning step S3 can be cleaned. can improve sexuality.

Then, when the second wash water W2 stored in the shared pipe 51 is replaced with the first wash water W1, the first wash water W1 is jetted from each nozzle 52. As shown in FIG.

At this time, in the first flow path 54, the second wash water W2 and the first wash water W1 stored in the common pipe 51 in the preparation step S1 are jetted from the first nozzle 52X at the X position. The total amount of water jetted from the second nozzle 52Y at the Y position is greater than the total amount of water. Details will be described later.

The second washing water W2 and the first washing water W1 sprayed into the inside of the bottle G come into contact with the inner surface of the bottle G or scatter inside the bottle G to wash away the contaminants. The washing water containing dirt components flows down the inner surface of the bottle G or drops inside the bottle G, temporarily stays at the neck G4, and flows out from the opening G1 into the washing chamber 30 through the notch 57a of the spacer 57. . Then, the cleaning water containing the contaminant component flows down to the partition member 38 in the lower part of the cleaning chamber 30 .

In this way, the first washing water W1 is sprayed from the first washing nozzle 41 of the rotating nozzle 40, and the second washing water W2 and the first washing water W1 are sprayed from the nozzle 52 of the rack 50 for a predetermined time, for example, 75 seconds. to clean the inner and outer surfaces of the bottle G.

Washing water containing dirt components flows down from the washing chamber 30 through the filter member 38b of the partition member 38 into the first tank 10, and is mixed with the first washing water W1 stored in the first tank 10. water is stored. At this time, among the dirt mixed in the cleaning water containing dirt components, dirt (such as leftover food) that is larger than the pores of the filter member 38b is collected by the filter member 38b. As a result, deterioration of the cleanliness of the first wash water W1 stored in the first tank 10 can be suppressed, and the bottles G can be washed with wash water of higher cleanliness.

The first wash water W1 stored in the first tank 10 flows again through the first wash water flow system 71 by the first wash water supply means 13, and is jetted from the rotary nozzle 40 and the nozzle 52 of the rack 50. and the bottle G is washed. In this manner, the first washing water W1 is circulated.

After continuing the drive for a predetermined time, the control unit 6 stops the first washing water supply means 13 .

The inflow of the first wash water W1 into the shared pipe 51 from the first inlet 53 stops, and the first check valve 53a closes. That is, both the first check valve 53a and the second check valve 55a are closed, and the common pipe 51 is in a state where the first wash water W1 is stored. Then, the control unit 6 keeps the washing water supply means 13 and 23 stopped for a predetermined time, for example, 3 seconds, in order to drain the bottle G, and the first washing step S3 ends.

(Second washing step)
After the first cleaning step S3, the controller 6 drives the second cleaning water supply means 23 to start the second cleaning step S4.

As shown in FIG. 22 , the second washing water supply means 23 sucks the second washing water W2 from the second tank 20 and discharges it to the second washing pipe 24 . The second washing water W2 discharged to the second washing pipe 24 branches from the second washing pipe 24 to the upper connection opening 32 and the lower connection opening 35, and flows through the respective second flow paths 34a and 35. 37a.

The second washing water W2 flowing into the upper connection opening 32 flows into the second washing nozzle 43 of the rotating nozzle 40 through the second joint portion 44, and flows downward from the injection port 43a for a predetermined time. , for example, for 12 seconds. The second washing water W2 in contact with the bottle G washes away the first washing water W1 adhering to the outer surface of the bottle G and the dirt components that could not be washed off in the first washing step S3. Then, the first cleaning water W1 and the second cleaning water W2 containing the dirt component not washed away in the first cleaning step S3 flow down to the partition member 38 in the lower part of the cleaning chamber 30. As shown in FIG.

The second wash water W2 that has flowed into the lower connection opening 35 flows through the second joint portion 63 of the connection portion 60, into the second connection pipe 64, and passes through the second check valve 55a. It flows into the shared pipe 51 from the second inlet 55 . At this time, the first check valve 53a is closed.

The second wash water W2 that has flowed into the common pipe 51 flows through the second flow path 56 in the common pipe 51 and is jetted upward from the jet ports 52a of the nozzles 52, respectively.

At this time, since the shared pipe 51 is filled with the first wash water W1 stored in the first wash step S3, it is pushed out by the second wash water W2 and First, the first wash water W1 is jetted into the bottle G for a predetermined time.

As a result, in the second cleaning step S4, the second cleaning water W2 is supplied from the second inlet 55 by the amount corresponding to the first cleaning water W1 stored in the shared pipe 51 in the first cleaning step S3. The second cleaning step S4 can be started quickly while reducing the amount of water used.

Further, it is not necessary to set the driving time of the second washing water supply means 23 to include the time (time lag) from the time when the common pipe 51 is filled with the washing water to the time when the washing water is sprayed from the plurality of nozzles 52. The cleaning time for the bottle G, which is the object to be cleaned, can be shortened as much as possible, and the energy required to inject the cleaning water W1 and W2 can be reduced.

Further, the cleaning water W1, W2 can be sprayed for a longer period of time from the start to the end of the second cleaning step S4, which is performed for a predetermined time, and the bottle G to be cleaned in the second cleaning step S4 can be cleaned. can improve sexuality.

In addition to the second washing water W2 sprayed into the bottle G from the nozzle 52 of the rack 50, the second washing water W2 is also sprayed from the second washing nozzle 43 of the rotating nozzle 40. The outer surface is cleaned. At this time, the second washing water W2 jetted from the second washing nozzle 43 cleans the outer surface of the bottle G and raises the temperature of the bottle G. As shown in FIG. Therefore, the second cleaning nozzle 43 sprays onto the dirt components adhering to the inner surface of the bottle G in addition to the dirt components adhering to the outer surface of the bottle G that could not be removed in the first cleaning step S3. Heat from the second washing water W2 acts. In addition, when the dirt component adhering to the bottle G is saccharides or oils, the fluidity of the dirt component is enhanced, making it easier to wash off.

As a result, more washing water can be sprayed onto the bottle G, which is an object to be washed, to improve the detergency of the bottle G, and the temperature of the bottle G can be raised to make it easier to remove stains adhered to the bottle G.例文帳に追加

Then, when the first wash water W1 stored in the common pipe 51 is replaced with the second wash water W2, the second wash water W2 is jetted from each nozzle 52. As shown in FIG.

At this time, in the second flow path 56, unlike the first flow path 54, the first wash water W1 and the second wash water W2 stored in the shared pipe 51 in the first washing step S3 are , the total amount of water jetted from the second nozzles 52Y at the Y position is smaller than the total amount of water jetted from the first nozzles 52X at the X position. Details will be described later.

The first wash water W1 and the second wash water W2 stored in the shared pipe 51 and sprayed into the bottle G come into contact with the inner surface of the bottle G or scatter inside the bottle G, causing the inner surface of the bottle G to Contamination components that have not been completely removed in the first cleaning step S3 attached to the surface are washed away. Washing water containing contaminants that could not be removed in the first washing step S3 flows down the inner surface of the bottle G or drops inside the bottle G and temporarily stays at the neck G4, while the spacer 57 is cut from the opening G1. The water flows out from the bottle G into the cleaning chamber 30 through the notch 57a. Then, the cleaning water containing the contaminants that could not be removed in the first cleaning step S3 flows down to the partition member 38 in the lower part of the cleaning chamber 30. As shown in FIG.

At this time, after the first wash water W1 stored in the shared pipe 51 is replaced with the second wash water W2, the second wash water W2 jetted from each nozzle 52 is injected into the bottle G. The first washing water W1 adhering to the surface and the dirt components that could not be removed in the first washing step S3 are washed away.

In this way, the second washing water W2 is sprayed from the second washing nozzle 43 of the rotary nozzle 40, and the first washing water W1 and the second washing water W2 are sprayed from the nozzle 52 of the rack 50 for a predetermined time, for example, 12 seconds. to clean the inner and outer surfaces of the bottle G.

Washing water containing contaminants that have not been removed in the first washing step S3 flows down from the washing chamber 30 through the filter member 38b of the partition member 38 into the first tank 10 and is stored in the first tank 10. It is mixed with the first wash water W1 and stored as the first wash water W1. At this time, among the contaminants mixed in the washing water, contaminants (such as leftover food) that are larger than the holes of the filter member 38b are collected by the filter member 38b. As a result, deterioration of the cleanliness of the first wash water W1 stored in the first tank 10 can be suppressed, and the bottles G can be washed with wash water of higher cleanliness.

Also, the amount of washing water in the first tank 10 increases by the amount of the second washing water W2 injected from the second washing nozzle 43 of the rotating nozzle 40 and the nozzle 52 of the rack 50 in the washing chamber 30. do. The increased washing water overflows from the upper end of the overflow/drainage plug 16 and is drained from the washing apparatus 1 through the drainage pipe 15a to the facility-side drainage ditch or the like.

As a result, the dirt component that has passed through the filter member 38b drifting near the water surface of the first tank 10 is drained together with the wash water, thereby increasing the cleanliness of the first wash water W1 stored in the first tank 10. can be suppressed.

In addition, when the second washing water W2 is clean water, the second washing water W2 has a higher degree of cleanliness (cleaner) than the first washing water W1, so it cannot be mixed with the first washing water W1. , the cleanliness of the first washing water W1 can be enhanced.

In this case, since the first wash water W1 is mixed with the second wash water W2, which is clean water, the concentration of the detergent in the first wash water W1 decreases. A signal is sent to the control unit 6 upon detection. The control unit 6 drives the detergent supply means (not shown) and controls the detergent to be supplied to the first tank 10 so as to have a predetermined concentration. Thereby, the detergent concentration of the first wash water W1 can be maintained.

The control unit 6 continues driving the second washing water supply means 23 for a predetermined time, and then stops the driving.

The wash water stops flowing into the shared pipe 51 from the second inlet 55, and the second check valve 55a closes. That is, the first check valve 53a and the second check valve 55a are both closed, and the shared pipe 51 is in a state where the second wash water W2 is stored. Then, after a predetermined period of time, for example, 3 seconds, has elapsed for draining the bottle G, the control unit 6 sounds a buzzer to inform the operator that the second washing step S4 has been completed. The washing step S4 of is completed.

(Unloading step)
The rack 50 is carried out from the cleaning chamber 30 after the second cleaning step S4 is completed.

As shown in FIGS. 4 and 6, the door portion 4 is opened, the rack 50 containing the bottles G is pulled out by hand, and carried out from the rack support portion 31 to a predetermined position in the rack standby portion 5. As shown in FIGS. At this time, the first connection pipe 62 and the second connection pipe 64 are deformed so as to follow the movement of the rack 50, and the connection portion 60 is rotated, so that the rack can be carried out smoothly. Then, the washed bottle G is taken out from the rack 50, and one washing is completed.

(Regarding the cleaning cycle)
If the bottle G is to be washed continuously after the first carrying-out step S5 is completed, the cleaning cycle is to repeat the second preparation step S1 to the carrying-out step S5. can be done.

In order to carry out the cleaning cycle, the second cleaning water W2 in the second tank 20, whose water level has been lowered by the second cleaning step S4, is filled up again and heated to a predetermined temperature. A second preparatory step S1 of heating is performed.

The second preparatory step S1 differs from the first preparatory step S1 in that it is carried out from a state in which the first tank 10 has already been filled with the first wash water W1. That is, in the second preparation step S1, the second cleaning water supply means 23 supplies the second cleaning water from the rotary nozzle 40 and the nozzle 52 of the rack 50 in order to store the cleaning water in the first tank 10. Without injecting W2, the second tank 20 is filled with the second cleansing water W2, which is clean water, and the temperature of the second cleansing water W2 is heated to a predetermined temperature and maintained. do.

Specifically, during the execution of the second cleaning step S4, the upper limit water level sensor 27a of the second tank 20 detects that the second cleaning water W2 is not full, and sends a signal to the controller 6. . The control unit 6 sends a signal to the electromagnetic valve 28a of the water supply pipe 28 to open it and start storing fresh water until the water supply pipe 28 is full. When the upper water level sensor 27a detects that the water level is full, a signal is sent to the control unit 6 to close the electromagnetic valve 28a. Then, the control unit 6 operates the second heating means 21 to heat the second washing water W2 and maintain it at a predetermined temperature.

When the second cleaning step S4 is completed, the first cleaning water W1 is stored in the first tank 10 until it is full. 17a is detected to be full, the first heating means 11 is operated, and the first washing water W1 is heated to a predetermined temperature and maintained at the predetermined temperature.

Then, the controller 6 determines that both the first wash water W1 stored in the first tank 10 and the second wash water W2 stored in the second tank 20 are filled at a predetermined temperature. As a state, it prepares for the next first cleaning step S3.

After the carry-out step S5, the operator takes out the washed bottles G from the rack 50, stores the unwashed bottles G to be washed next in the rack 50, and moves the rack 50 containing the bottles G to the washing chamber 30. Then, the second carrying-in step S2 is carried out. Thereafter, the first cleaning step S3 for the second time is started, followed by the second cleaning step S4 and the unloading step S5.

When repeating the cleaning cycle, the second cleaning water W2 is stored in the shared pipe 51 when the first second cleaning step S4 is completed. Therefore, in the next second first washing step S3, the second washing water W2 stored in the shared pipe 51 is injected toward the inside of the bottle G before the first washing water W1 is injected. can do.

As a result, the second washing water W2, which has a higher temperature than the first washing water W1, heats the bottles G, which are the objects to be washed, and the dirt components adhering to the bottles G in advance, thereby increasing the fluidity of the dirt components. can increase Further, the removal of contaminants by the first washing water W1 can be accelerated, and the washability of the bottle G can be improved.

In addition, since the cleaning performance of the bottle G with the first cleaning water W1 is improved, the time for performing the first cleaning step S3 can be shortened, and the length of the cleaning time per cleaning can be shortened as much as possible. and the energy for injecting the first cleaning water W1 can be reduced.

(Regarding changing the length of time for the washing step)
In the cleaning apparatus 1 of Embodiment 1, the control of each member in the control section 6 is changed by operating the operation section 7, and the length of time for performing the first cleaning step S3 and the second cleaning step S4 are changed. You can change the length of time and By changing the length of time for performing the first cleaning step S3 and the length of time for performing the second cleaning step S4, the amount of energy used for cleaning is not greatly increased. , the bottle G can be washed more reliably. A method of cleaning the cleaning apparatus 1 having such a configuration will be described below.

Before explaining the method here, it is assumed that, unlike the first embodiment, the first washing water W1 is caused to flow into the shared pipe 51 from the first inlet 53 in the first washing step S3, A case in which the second washing water W2 is caused to flow into the shared pipe 51 from the first inlet 53 in the second washing step S4 will also be described.

In general, in a batch-type cleaning apparatus for an object to be cleaned, such as the cleaning apparatus 1 of Embodiment 1, the total amount of cleaning water injected from the nozzles closest to the inlet in each cleaning of the object to be cleaned is is smaller than the total amount of washing water jetted from other nozzles.

Therefore, in the common pipe 51 shown in FIG. 51, the total amount of the first washing water W1 jetted from the first nozzles 52X at the X position in the first washing step S3 in one washing of the bottle G is It is less than the total amount of the first washing water W1 jetted from the nozzles 52 . On the other hand, the total amount of first wash water W1 injected from the second nozzles 52Y at the Y position is greater than the total amount of first wash water W1 injected from the first nozzles 52X at the X position.

Also, the total amount of the second washing water W2 injected from the first nozzles 52X at the X position in the second washing step S4 is less than the total amount of the second washing water W2 injected from the other nozzles 52. , the total amount of the second cleaning water W2 ejected from the second nozzles 52Y at the Y position is greater than the total amount of the first cleaning water W1 ejected from the first nozzles 52X at the X position.

As a result, the total amount of washing water W1 and W2 jetted from the first nozzle 52X at the X position is less than the total amount of washing water W1 and W2 jetted from the other nozzles 52 when the bottle G is washed once. Therefore, the total amount of cleaning water W1, W2 ejected from the second nozzle 52Y at the Y position is extremely larger than the total amount of cleaning water W1, W2 ejected from the first nozzle 52X at the X position.

Although there is a difference depending on the length of time during which the washing steps S3 and S4 are performed, the bottle G washed by the nozzles 52, especially the first nozzles 52X, which jet the washing water W1 and W2 in an extremely small amount, It may not be possible to wash to the desired level. Further, there is a possibility that more than necessary washing water is sprayed from the nozzles 52, particularly the second nozzle 52Y, which jets an extremely large amount of the washing water W1 and W2.

Also, hypothetically, washing waters W1 and W2 are caused to flow into the shared pipe 51 from the second inlet 55, which is the same inlet in both the cleaning steps S3 and S4, and the second flow path 56, which is the same flow path, is formed. Even when it is made to flow, the total amount of the washing water W1 and W2 jetted from the nozzle 52 is extremely small or extremely large.

In these cases, the bottle G is cleaned with the cleaning water W1 and W2 ejected from the first nozzle 52X at the X position, and the bottle G is cleaned with the cleaning water W1 and W2 ejected from the second nozzle 52Y at the Y position. When trying to wash G to a desired level, the first washing step S3 is performed with reference to the nozzle 52 that jets out the total amount of washing water W1 and W2 that is jetted in one washing of the bottle G to an extremely small amount. and the length of time for performing the second cleaning step S4 are adjusted. By adjusting the length of time during which the washing steps S3 and S4 are performed, the total amount of the washing water W1 and W2 sprayed for washing the bottle G each time is adjusted.

For example, in both cleaning steps S3 and S4, the cleaning water W1 and W2 are caused to flow into the shared pipe 51 from the first inlet 53, which is the same inlet, and flow through the same first flow path 54. In this case, the total amount of washing water W1 and W2 ejected from the first nozzle 52X at the X position where the total amount of washing water W1 and W2 to be jetted is extremely small in one washing of the bottle G is increased. A change is made to extend the length of time during which the cleaning steps S3 and S4 are performed.

As a result, the bottle G cleaned with the cleaning water W1 and W2 ejected from the first nozzle 52X at the X position and the bottle G cleaned with the cleaning water W1 and W2 ejected from the second nozzle 52Y at the Y position are: In both cases, washing can be performed to a desired level. More washing water W1, W2 is jetted more than necessary, and the energy used by the washing water supply means 13, 23 for discharging the washing water W1, W2 is uselessly increased.

On the other hand, in the cleaning method using the cleaning apparatus 1 of Embodiment 1, as shown in FIG. and flow in the first flow path 54 .

As a result, in the first cleaning step S3 per one time, the total amount of the first cleaning water W1 jetted from the first nozzles 52X at the X position shown in FIG. The total amount of the first washing water W1 injected from the second nozzles 52Y at the Y position is less than the total amount of the first washing water W1 injected from the first nozzles 52X at the X position. than the total amount of washing water W1.

Further, as shown in FIG. 22, in the second cleaning step S4, the second cleaning water W2 is caused to flow from the second inlet 55 to the shared pipe 51, and flow through the second flow path 56. there is

As a result, in the second cleaning step S4 per time, the total amount of the second cleaning water W2 ejected from the second nozzles 52Y at the Y position shown in FIG. The total amount of the second washing water W2 injected from the first nozzles 52X at the X position is less than the total amount of the second washing water W2 injected from the second nozzles 52Y at the Y position. than the total amount of washing water W2.

In this manner, the positions of the inflow ports 53 and 55 through which the washing waters W1 and W2 flow into the shared pipe 51 are different between the first washing step S3 and the second washing step S4. flow through different flow paths 54 and 56, the nozzle 52 with a small total amount of water in the first cleaning step S3 can increase the total amount of water in the second cleaning step S4, and in the first cleaning step S3 The nozzles 52 with a large total amount of water can reduce the total amount of water in the second cleaning step S4.

As a result, when the bottle G is washed once, the total amount of the washing water W1 and W2 jetted from the first nozzle 52X at the X position closest to the first inlet 53 to the bottle G, It is possible to equalize the total amount of the washing water W1 and W2 that is injected into the bottle G from the second nozzle 52Y at the Y position that is closest to the inlet 55 of No. 2.

By equalizing the total amounts of the washing waters W1 and W2 in this way, for example, the bottle G, which could not be washed to the desired level, can be washed to the desired level. When changing the length of time for performing the cleaning step S3 and the length of time for performing the second cleaning step S4, the length of time for performing the first cleaning step S3 and/or the length of time for performing the second cleaning step S4 The amount of change in the length of time to do is as short as possible. That is, the length of time for performing the first cleaning step S3 and/or the length of time for performing the second cleaning step S4 can be shortened as compared to the case where the equalization is not performed.

As a result, the driving time of the cleaning water supply means 13, 23 for ejecting the cleaning water W1, W2 in the cleaning steps S3, S4 can be shortened, and the total amount of cleaning water ejected from the entire plurality of nozzles 52 can be reduced. and the energy for injecting wash water can be reduced.

In addition, compared to the case where equalization is not performed, the bottle G, which is the object to be cleaned, can be cleaned more reliably without greatly increasing the consumption of energy used for cleaning.

Also, as shown in FIG. 23, the total amount of the second washing water W2 injected in the second washing step S4 is reduced compared to the case where the total amounts of the washing water W1 and W2 are not equalized. , the first nozzle 52X at the X position can be more, and the second nozzle 52Y at the Y position can be less. In other words, a portion of the second washing water W2 ejected from the second nozzles 52Y at the Y position more than necessary accounts for the total amount of the second washing water W2 ejected from the first nozzles 52X at the X position. You can make up for the shortfall.

It should be noted that the length of time for performing the first cleaning step S3 and the length of time for performing the second cleaning step S4 may be extended or shortened. may be extended or shortened only in length. Alternatively, either one may be extended and the other shortened.

(Regarding the first wash water stored in the common pipe)
Further, in the washing of the bottle G once, in the second washing step S4, before the second washing water W2 flowing into the shared pipe 51 from the second inlet 55 is sprayed from the plurality of nozzles 52, Then, the first washing water W1 stored in the shared pipe 51 in the first washing step S3 is jetted for a predetermined time.

At this time, the first wash water W1 stored in the shared pipe 51 flows into the shared pipe 51 from the second inlet 55, and is , so as to be extruded from a plurality of nozzles 52 .

As a result, the total amount of the first wash water W1 stored in the shared pipe 51 injected from the first nozzles 52X at the X position is equal to the total amount of the first wash water W1 injected from the second nozzles 52Y at the Y position. , and the total amount of the first wash water W1 stored in the shared pipe 51 injected from the second nozzle 52Y at the Y position is the total amount of water injected from the first nozzle 52X at the X position. It is less than the total amount of washing water W1 of 1.

That is, the first washing water W1 stored in the shared pipe 51 is stored from the first nozzle 52X at the X position where the total amount of the first washing water W1 injected in the first washing step S3 is small. The second nozzle 52Y at the Y position where the total amount of the first washing water W1 injected in the first washing step S3 was large is the stored first washing water W1. A small amount of washing water W1 is injected.

As a result, the total amount of the first washing water W1 jetted from the first nozzle 52X at the X position and the second nozzle 52Y at the Y position can be equalized in one washing of the bottle G. .

When the first wash water W1 is wash water containing a detergent, the cleaning effect (cleaning degree) of the first wash water W1 with the detergent can be equalized among the plurality of bottles G.

In addition, the first wash water W1 is caused to flow into the shared pipe 51 from the first inlet 53 by the amount corresponding to the first wash water W1 stored in the shared pipe 51 in the first washing step S3. The length of time can be shortened.

As a result, the driving time of the first cleaning water supply means 13 for ejecting the first cleaning water W1 in the first cleaning step S3 can be shortened, and the cleaning water ejected from the entire plurality of nozzles 52 can be shortened. It is possible to reduce the total amount of water and reduce the energy required to inject the cleaning water W1, W2.

In addition, compared to the case where equalization is not performed, the bottle G, which is the object to be cleaned, can be cleaned more reliably without greatly increasing the consumption of energy used for cleaning.

In the first embodiment, the common pipe 51 is one continuous pipe line, and has been described as an example in which the first flow path 54 and the second flow path 56 are formed. Alternatively, a pipe forming the first flow path 54 and a pipe forming the second flow path 56 may be provided adjacent to each other, and a plurality of nozzles 52 communicating with each of the pipes may be provided.

Specifically, it is formed by a single pipeline having one end and the other end and both ends are closed, and the pipeline has an inlet on one end side and is closed on the other end side. form a path. Two pipes configured in this way are prepared, one pipe is used as the first pipe 81 forming the first flow path 54, and the other pipe is used as the second pipe forming the second flow path 56. 82 are placed adjacent to each other.

A plurality of nozzles 52 are attached to predetermined positions on the first pipe 81 and the second pipe 82, respectively, and when the first pipe 81 and the second pipe 82 are arranged adjacently, the first The plurality of nozzles 52 of each of the pipes 81 and the plurality of nozzles 52 of each of the second pipes 82 are configured to be adjacent to each other. In this case, it is preferable to configure so that adjacent nozzles 52 can both be inserted into the bottle G from the opening G1 of the bottle G, which is the object to be cleaned.

A first inlet 53 is provided on either end of the first pipe 81, a second inlet 55 is provided on one of the ends of the second pipe 82, and the first pipe When the 81 and the second pipe 82 are arranged adjacent to each other, the first inlet 53 and the second inlet 55 are arranged at different positions. For example, when the first pipe 81 and the second pipe 82 are formed by pipes having substantially the same shape, the end of the first pipe 81 on the side where the first inlet 53 is provided and the second pipe The distal end of 82 is arranged so as to be adjacent. Furthermore, the end of the second pipe 82 on the side where the second inlet 55 is provided and the end of the first pipe 81 on the terminal side are arranged so as to be adjacent to each other. By arranging in this way, the positions of the first inlet 53 and the second inlet 55 are different.

Then, among the plurality of nozzles 52 of the first pipe 81, the nozzle with the shortest flow path length from the first inlet 53 is the first nozzle 52X at the X position, and the plurality of nozzles of the second pipe 82 Among the nozzles 52, the nozzle having the shortest flow path length from the second inlet 55 is designated as the second nozzle 52Y at the Y position.

By configuring in this way, the flow path length from the first inlet 53 of the first pipe 81 to the first nozzle 52X at the X position is is shorter than the channel length to the nozzle 52 of the first pipe 81 adjacent to the second nozzle 52Y at the Y position of . That is, the first nozzle 52X at the X position is the distance from the first inlet 53 of the first pipe 81 to the second nozzle at the Y position of the second pipe 82 from the first inlet 53. The position is closer than the distance to the nozzle 52 of the first pipe 81 adjacent to 52Y.

Conversely, the flow path length from the first inlet 53 of the first pipe 81 to the nozzle 52 of the first pipe 81 adjacent to the second nozzle 52Y at the Y position of the second pipe 82 is It is longer than the channel length from the first inlet 53 to the first nozzle 52X at the X position. That is, the nozzle 52 of the first pipe 81 adjacent to the second nozzle 52Y at the Y position of the second pipe 82 is the distance from the first inlet 53 of the first pipe 81 to the first flow. The position is farther than the distance from the inlet 53 to the first nozzle 52X at the X position.

Also, the flow path length from the second inlet 55 of the second pipe 82 to the second nozzle 52Y at the Y position is the first is shorter than the length of the passage to the nozzle 52 of the second pipe 82 adjacent to the nozzle 52X. That is, the second nozzle 52Y at the Y position is the distance from the second inlet 55 of the second pipe 82 to the distance from the second inlet 55 to the first nozzle at the X position of the first pipe 81. The position is closer than the distance to the nozzle 52 of the second pipe 82 adjacent to 52X.

Conversely, the flow path length from the second inlet 55 of the second pipe 82 to the nozzle 52 of the second pipe 82 adjacent to the first nozzle 52X at the X position of the first pipe 81 is It is longer than the channel length from the second inlet 55 to the second nozzle 52Y at the Y position. That is, the nozzle 52 of the second pipe 82 adjacent to the first nozzle 52X at the X position of the first pipe 81 is the distance from the second inlet 55 of the second pipe 82 to the second flow. The position is farther than the distance from the inlet 55 to the second nozzle 52Y at the Y position.

Even with this configuration, in the first cleaning step S3, the first nozzle 52X at the X position closest to the first inlet 53 in the first pipe 81 and the first nozzle 52X in the second pipe 82 The total amount of the first washing water W1 injected from the nozzles 52 of the first pipe 81 adjacent to the second nozzle 52Y at position Y, which is closest to the second inlet 55, is The first nozzles 52X are fewer than the nozzles 52 of the first pipe 81 adjacent to the second nozzles 52Y at the Y position, and conversely, the first nozzles 52X adjacent to the second nozzles 52Y at the Y position are fewer. The number of nozzles 52 in the pipe 81 is greater than the number of the first nozzles 52X at the X position.

Further, in the second cleaning step S4, the second nozzle 52Y at the Y position closest to the second inlet 55 in the second pipe 82 and the first inlet 53 in the first pipe 81 The total amount of the second washing water W2 jetted from the nozzles 52 of the second pipe 82 adjacent to the first nozzle 52X at the X position, which is closest to the position of the second nozzle 52Y at the Y position, is The number of nozzles 52 of the second pipe 82 adjacent to the first nozzle 52X at the X position is less than the number of nozzles 52 of the second pipe 82 adjacent to the first nozzle 52X at the X position. The number of nozzles 52Y is greater than that of the second nozzles 52Y at the Y position, and the same effect as described in the present embodiment can be exhibited.

As a result, of the plurality of nozzles 52 communicating with the first pipe 81 and the second pipe 82, the first nozzle 52X at the X position and the second pipe adjacent to the first nozzle 52X at the X position 82, the second nozzle 52Y at the Y position, and the nozzles 52 in the first pipe 81 adjacent to the second nozzle 52Y at the Y position. The difference between the cleaning step S3 and the second cleaning step S4 is that the total amount of cleaning water sprayed onto the bottle G, which is the object to be cleaned, can be equalized in each cleaning.

Then, the first washing step S3 and/or the first washing step S3 and/or the nozzle 52 jetting a desired total amount of washing water are jetted from the nozzles 52 having a smaller total amount of jetting washing water in one washing. When changing the length of time for performing the second cleaning step S4, the first nozzle 52X at the X position and the nozzle 52 included in the second pipe 82 adjacent to the first nozzle 52X at the X position, Compared to the case where the total amount of washing water jetted from the second nozzle 52Y at the position Y and the nozzle 52 in the first pipe 81 adjacent to the second nozzle 52Y at the Y position is not equalized, Even if the total amount of washing water injected from the nozzle is set to the desired total amount, the length of time for performing the first washing step S3 and/or the second washing step S4 can be shortened.

As a result, it is possible to reduce the total amount of the cleaning water W1, W2 ejected from the entire plurality of nozzles 52, and reduce the energy required to inject the cleaning water W1, W2.

In addition, compared to the case where equalization is not performed, the bottle G, which is the object to be cleaned, can be cleaned more reliably without greatly increasing the consumption of energy used for cleaning.

In addition, the first check valve 53a is provided at the first inlet 53 to prevent the wash water in the first pipe 81 from flowing back to the first wash water supply means 13 side. After one cleaning step S3, the first cleaning water W1 can be stored in the first pipe 81. FIG.

As a result, in performing the cleaning cycle, in the second first cleaning step S3, the first cleaning water W1 stored in the first pipe 81 in the first first cleaning step S3 is removed from the first cleaning water W1. The first cleaning water W1 can be quickly jetted from the plurality of nozzles 52 while reducing the amount of the first cleaning water W1 flowing in from one inlet 53 .

In addition, the second check valve 55a is provided at the second inlet 55 to prevent the wash water in the second pipe 82 from flowing back to the second wash water supply means 23. After the second cleaning step S<b>4 , the second cleaning water W<b>2 can be stored in the second pipe 82 .

As a result, in performing the cleaning cycle, in the second cleaning step S4 for the second time, the second cleaning water W2 stored in the second pipe 82 in the first second cleaning step S4 is removed from the second cleaning water W2. The second wash water W2 can be quickly jetted from the plurality of nozzles 52 while reducing the amount of the second wash water W2 flowing in from the inlet 55 of No. 2.

The driving time of the cleaning water supply means 13 and 23 includes the time (time lag) from the time when the first pipe 81 or the second pipe 82 is filled with the cleaning water to the time when the cleaning water is jetted from the plurality of nozzles 52. Therefore, it is possible to shorten the cleaning time of the bottle G, which is the object to be cleaned, as much as possible, and to reduce the energy required to inject the cleaning water.

In addition, when the cleaning steps S3 and S4 are performed for a predetermined time, respectively, the cleaning steps S3 and S4 are more effective than the case where the cleaning water is not stored in the first pipe 81 and the second pipe 82. The washing water W1, W2 can be sprayed from the plurality of nozzles 52 for a longer period of time from the start to the end, and the washing performance of the bottle G, which is the object to be washed, can be improved.

Although the case where the first pipe 81 and the second pipe 82 are arranged adjacent to each other together with the plurality of nozzles 52 provided respectively has been described, for example, two regions in the shared pipe 51 along the pipe length direction One of the pipes is used as the first pipe 81 that forms the first flow path 54, and the other pipe is used as the second pipe 82 that forms the second flow path 56. You may divide and comprise. In other words, the pipelines partitioned into two areas are also adjacent to each other. In this case, the plurality of nozzles are provided to communicate with the first pipe 81 and the second pipe 82 . For example, as one nozzle having two injection ports, the inside of the nozzle is partitioned into two regions along the pipe length direction, and one injection port is communicated with the first pipe 81, and the other injection port and the first pipe 81 are communicated. It may be configured to communicate with the second pipe 82 . In this case as well, the effects as described above can be exhibited in the same manner.

In addition, although the predetermined temperature of the washing water is 60° C. for the first washing water W1 and 80° C. for the second washing water W2, it is not limited to this. It can be appropriately changed according to the type of dirt component to be washed.

Also, the cleaning apparatus 1 may be configured without either the first tank 10 and the first cleaning water supply means 13 or the second tank 20 and the second cleaning water supply means 23 . Alternatively, the configuration may be such that both are not provided.

If the first tank 10 and the first washing water supply means 13 are not provided, for example, a water pipe for supplying the first washing water W1 is connected to the first washing pipe 14 . The first heating means 11 and the like for heating the first washing water W1 are preferably provided in-line in the first washing pipe 14 .

If the second tank 20 and the second washing water supply means 23 are not provided, for example, a water pipe for supplying the second washing water W2 is connected to the second washing pipe 24 . Also, the second heating means 21 for heating the second washing water W2 and the like are preferably provided in-line in the second washing pipe 24 .

Further, since the connection part 60 is detachably connected to the lower connection opening 35, a plurality of racks 50 corresponding to the shape and size of the bottles G are prepared, Rack 50 may be replaced.

Further, the object to be washed is not limited to the bottle G, and tableware or the like may be used. In that case, the storage space 50a of the rack 50 does not have a lattice shape in which the bottles G are stored upright in an inverted position. It may have a screen-like shape on which the object to be cleaned can be placed in a downward position. As a result, it is possible to perform cleaning with a uniform degree of cleaning in one cleaning.

Further, the nozzle connected to the upper connection opening 32 is not limited to the rotary nozzle 40, and may be a nozzle fixed inside the cleaning chamber 30, for example, a shared pipe 51.

Further, if the bottle G is heavily soiled, a preliminary cleaning step using the second cleaning water flow system 72 may be performed as in the second cleaning step S4 before performing the first cleaning step S3. good too. As a result, the high-temperature second washing water W2 can heat the object to be washed and the dirt component, and the removal of the dirt component with the first washing water W1 can be accelerated in the first washing step S3. A pre-wash can be performed.

In addition, immediately before the first cleaning step S3, the second cleaning water W2 having a higher temperature than the first cleaning water W1 can be stored in advance in the shared pipe 51, so that the carrying-in step S2 in the cleaning cycle can be eliminated. During the execution, the second washing water W2 having a higher temperature than the second washing water W2 stored in the common pipe 51 whose temperature has been lowered is poured into the bottle G in the first washing step S3. can be jetted. As a result, it is possible to improve the cleaning performance with the first cleaning water W1 in the first cleaning step S3.

In the cleaning cycle, after carrying out the unloading step S5 and before carrying in the next loading step S2, the door part 4 is once closed, the first cleaning step S3 is carried out in advance, and the first cleaning step S3 is carried out in the shared pipe 51. The water W1 may be stored. As a result, in the first cleaning step S3, since the shared pipe 51 is filled with the first cleaning water W1, the jetting of the first cleaning water W1 from the plurality of nozzles 52 is started in the first cleaning step S3. In some cases, the first washing water W1 can be the washing water that first contacts the object to be washed. In particular, when the first washing water W1 containing detergent is used, the cleaning effect of the detergent can be exhibited for a longer period of time in the first washing step S3 by bringing the detergent into contact with the object to be washed from the beginning.

The washing apparatus 1 replaces the rotary nozzle 40 attached to the lower connection opening 35 from a normal batch-type dishwasher in which the rotary nozzle 40 is attached to the upper connection opening 32 and the lower connection opening 35, and the rack 50 is used as the connection part. It is also possible to use a normal dishwasher as a bottle washer by attaching it together with 60 to the lower connection opening 35 .
