Description

  The present invention relates to a cleaning liquid supply apparatus that dissolves a powder detergent in a solvent such as warm water to generate a cleaning liquid and supplies the cleaning liquid to a dishwasher.

  In restaurants and the like, since a large amount of tableware is used in a short time, a dishwasher for efficiently cleaning the tableware is used. The dishwasher sprays washing water, which is diluted with warm water, onto the tableware stored in the washing room to wash the dishes, and then rinses the tableware by spraying rinse water onto the dishes to wash away dirt and washing liquid attached to the dishes. . The washing water is supplied to the washing machine from a washing water tank provided adjacent to the washing machine, and the washing water washed away by the rinse water is filtered by the filter and then returned to the washing water tank again.

  Thus, since the wash water in the wash water tank is diluted by the rinse water every time the dishes are washed, the washing liquid concentration of the wash water gradually decreases while washing is performed. For this reason, the dishwasher is provided with a cleaning liquid supply device for supplying a cleaning liquid to the cleaning water. The cleaning liquid supply device has a concentration sensor that detects the cleaning liquid concentration in the cleaning water tank, and supplies the cleaning liquid to the cleaning water tank based on the detection result of the concentration sensor to adjust the concentration of the cleaning water. To do.

As conventional cleaning liquid supply apparatuses, there are those described in Patent Documents 1 and 2. In these cleaning liquid supply devices, whenever the concentration sensor detects a decrease in the cleaning liquid concentration of the cleaning water,
A cleaning liquid is generated by dissolving a powder detergent in a solvent such as warm water, and this cleaning liquid is supplied to a cleaning water tank.

  In the cleaning liquid supply device described in Patent Document 1, a cartridge container filled with a powder detergent is attached to the apparatus with the mouth of the cartridge container facing downward, and hot water is injected into the cartridge container from a nozzle provided below the cartridge container. And dissolve the detergent. Since the obtained cleaning liquid descends to the lower part of the apparatus, it is recovered and supplied to the cleaning water tank.

  Thus, in the cleaning liquid supply apparatus of Patent Document 1, since the nozzle for supplying warm water is arranged at the lower part of the powder detergent, a part of the cleaning liquid enters the nozzle and the cleaning liquid is supplied to the hot water supply source. There is a possibility of backflow. For this reason, in the apparatus of patent document 1, the vacuum breaker for preventing the back flow of a washing | cleaning liquid is provided in piping for hot water supply.

  On the other hand, in the cleaning liquid supply apparatus of Patent Document 2, a container for containing a detergent is incorporated in the apparatus, and a nozzle for injecting hot water downward is provided at the upper center of the container. A mesh plate is attached to the inner peripheral surface of the container, and the cleaning solution obtained by dissolving the detergent in warm water passes through the mesh plate and passes through the gap between the inner periphery of the container and the mesh plate. It discharges from the opening provided. The cleaning liquid supply device collects the discharged cleaning liquid and supplies it to the cleaning water tank.

  As described above, in the cleaning liquid supply apparatus of Patent Document 2, since warm water is jetted from the center of the container toward the outside, the elution of the detergent is faster toward the outside. Therefore, a mesh plate for separating and recovering the cleaning liquid is attached along the inner peripheral surface of the container so that the cleaning liquid generated in the container can be efficiently recovered from the container. In such an apparatus configuration, it is necessary to attach a large mesh plate that can cover the side surface of the inner periphery of the container to the container. As described above, the apparatus disclosed in Patent Document 1 requires a vacuum breaker, and the apparatus disclosed in Patent Document 2 requires a large mesh, which increases the cost of the entire apparatus.

  The present invention has been made to solve the above-described problems associated with the conventional cleaning liquid supply apparatus. That is, an object of the present invention is to provide a low-cost cleaning liquid supply device that does not require a vacuum breaker or a large mesh plate.

A cleaning liquid supply apparatus according to an embodiment of the present invention includes a first container in which a powder detergent is accommodated, a vertical extension extending into the first container, and a lower end connected to an opening formed at the bottom of the first container. And a spray means for spraying a solvent from above onto the powder detergent contained in the first container via a spray nozzle disposed outside the mesh pipe, and the spray means comprises a mesh A nozzle tube extending in a direction perpendicular to the central axis of the tube and supported rotatably around the central axis, wherein the injection nozzle is formed on the lower surface of the nozzle tube, and the injection means is configured to connect the injection nozzle to the mesh tube. The solvent is jetted while rotating or swinging around the central axis, the detergent powder is dissolved in the jetted solvent to produce a washing liquid, and the washing liquid flowing out from the first container is supplied through the mesh tube and the opening. It has become.
Moreover, the cleaning liquid supply apparatus according to the embodiment of the present invention includes a first container in which a powder detergent is accommodated, a lower end in an opening formed in the bottom of the first container, extending vertically in the first container. A mesh pipe connected to the first pipe, a jet means for jetting the solvent from above to the powder detergent contained in the first container via a jet nozzle arranged outside the mesh pipe, and supplying the solvent to the jet means A solvent supply pipe, and the solvent supply pipe passes through the opening of the first container and the inside of the mesh pipe and is connected to the jetting means. The washing liquid is obtained by dissolving the powder detergent in the jetted solvent. The cleaning liquid flowing out from the first container is supplied through the mesh tube and the opening.

  When the nozzle is arranged in the upper center part of the container as in Patent Document 2, the nozzle injects the hot water in a substantially conical shape so that the hot water can be injected to the entire powder detergent with the nozzle whose position is fixed. In such a nozzle, since the flow rate of the warm water tends to increase as the portion is located outside the cone, more powder detergent from the outside in the container is dissolved in the warm water. For this reason, while continuing the injection of warm water, the height of the powder detergent is low in the outer portion and higher in the inner portion, and the cleaning liquid easily flows from the inner side toward the outer side. For this reason, in the structure of patent document 2, it was necessary to provide a large mesh board along the container inner wall.

  In the present invention, the injection nozzle for injecting the solvent is arranged at a position shifted from the outside of the container to the outside of the container. For example, this nozzle is centered on the central axis of the mesh tube (that is, the center of the container). The solvent can be sprayed substantially uniformly on the upper surface of the powder detergent by rotating or swinging. For this reason, the hot water is not concentrated and sprayed on the outer side of the inside of the container, and the cleaning liquid moves from the inner peripheral side of the container toward the mesh tube side, and passes through the openings inside the mesh tube and the bottom surface of the first container. Move through to the second container. Thus, in the detergent liquid supply apparatus of the present invention, it is possible to move the cleaning liquid to the second container below even if the mesh tube is relatively small compared to the mesh plate in Patent Document 2. .

  In the cleaning liquid supply apparatus of the present invention, since the nozzle is provided above the powder detergent, the cleaning liquid does not adhere to the nozzle and a vacuum breaker is not required.

  As described above, according to the present invention, a low-cost cleaning liquid supply apparatus that does not require a large mesh plate or a vacuum breaker is realized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a block diagram of the dishwashing system of this embodiment. The dish washing system 1 of this embodiment performs washing by jetting washing water onto the dishes arranged in the washing room 10, and then rinsing water is jetted onto the dishes to wash away dirt and washing water.

  The washing water is stored in a washing water tank 30 disposed under the washing chamber 10. The washing water is pumped out from the washing water tank 30 by the washing water pump 44 and is sprayed toward the upper tableware from the washing water injection unit 12 disposed in the lower part of the washing chamber 10. The washing water is obtained by diluting the washing liquid with water.

  The washing water injection unit 12 is a tubular member extending in the horizontal direction, and is supported at the center thereof so as to be rotatable around the vertical axis. A plurality of (five in FIG. 1) nozzles for injecting cleaning water are arranged on the upper part of the pipe side surface of the cleaning water injection unit 12. Further, the cleaning water jetting unit 12 is driven to rotate by the water pressure of the cleaning water to be sent, so that the cleaning water can be jetted substantially evenly to the tableware in the cleaning chamber 10.

  The rinsing water is clean drinking water stored in the rinsing water tank 20. The rinsing water stored in the rinsing water tank 20 is pumped out by the rinsing water pump 42 and is jetted from the rinsing water jetting unit 14 disposed in the upper part of the cleaning chamber 10 toward the lower tableware.

  Similar to the washing water injection unit 12, the rinse water injection unit 14 is a tubular member extending in the horizontal direction, and is supported rotatably around the vertical axis at the center thereof. A plurality of nozzles for injecting rinsing water are arranged at the lower part of the pipe side surface of the rinsing water injection unit 14. Moreover, the rinse water injection part 14 is rotationally driven by the water pressure of the rinse water sent, and can thereby rinse water into the tableware in the washing | cleaning room 10 substantially equally.

  The cleaning chamber 10 and the cleaning water tank 30 communicate with each other through the opening 18 provided with the filter 16. The cleaning water and the rinsing water sprayed into the cleaning chamber 10 are filtered by the filter 16. , Returned to the washing water tank 30. Inside the washing water tank 30, there is provided a drain pipe 32 that penetrates the bottom surface of the tank and extends vertically upward. When the water level of the cleaning water in the cleaning water tank 30 exceeds the height of the upper end of the drain pipe 32, the cleaning water 30 is drained from the drain pipe 32 and the cleaning water does not overflow from the cleaning water tank 30 into the cleaning chamber. ing.

  As described above, since the washing water and the rinsing water flow into the washing water tank 30, the washing liquid concentration in the washing water tank 30 gradually decreases as the dish washing is repeated. Therefore, the cleaning liquid concentration is monitored by the concentration sensor 152 provided in the cleaning water tank 30, and the cleaning liquid is supplied from the cleaning liquid supply device 100 when the cleaning liquid concentration falls below a predetermined threshold value.

  In this embodiment, the cleaning liquid supply device 100 generates a cleaning liquid by dissolving a powder detergent in warm water as a solvent, and supplies the cleaning liquid to the cleaning water tank 30. Details of the cleaning liquid supply apparatus 100 will be described below.

  2 and 3 are a front view and a bottom view of the cleaning liquid supply apparatus 100 of the present embodiment, respectively. FIG. 4 is a II diagram of FIG. The cleaning liquid supply apparatus 100 of the present embodiment dissolves a powder detergent in a warm water with a container part 110, an electromagnetic valve unit 120 for switching whether or not the warm water supplied from the hot water supply pipe 122 is sent into the container part 110, and the like. The cleaning liquid discharge part 132 for taking out the cleaning liquid obtained from the bottom of the container part 110 and sending it to the cleaning liquid discharge pipe 134, and the control part 150 in which a circuit board and the like are stored.

  As shown in FIG. 4, the container part 110 has a double bottom structure in which the upper container 111 is stacked on the lower container 112, and the powder detergent P is deposited on the upper container 111. A hot water introduction pipe 112b inserted into the downstream connector 124 of the electromagnetic valve unit 120 projects downward substantially at the center of the bottom 112a of the lower container 112. The upper part of the hot water introduction pipe 112 b protrudes upward in the lower container 112, and the tip 112 c passes through the opening 111 b provided in the bottom surface 111 a of the upper container 111 and enters the upper container 111. In.

  The hot water introduction pipe 112b is connected to the relay pipe 162 at its upper end 112c. The relay pipe 162 is a pipe extending substantially vertically upward from the lower end inside the upper container 111 to the vicinity of the upper end, and a nozzle tube 164 is attached to the upper end thereof. Therefore, when the electromagnetic valve 120 is opened and hot water is introduced into the relay pipe 162, the hot water reaches the upper end of the relay pipe 162 and is supplied to the nozzle tube 164. A flow rate adjustment valve 166 is provided in the middle of the relay pipe 162 to control the flow rate of hot water supplied to the nozzle pipe 164 within a predetermined range.

  The structure of the nozzle tube 164 will be described below. FIG. 5 is a top view of the nozzle tube 164, and FIG. 6 is a side view of the nozzle tube 164. FIG. 7 is a sectional side view of the nozzle tube 164. As shown in FIGS. 6 and 7, the nozzle tube 164 includes a hollow horizontal portion 164 a that is disposed in a substantially horizontal direction, and a vertical portion 164 b that extends downward from the center of the horizontal portion 164. The vertical portion 164 b is inserted into a bearing portion 162 a formed at the upper end of the relay pipe 162, and the nozzle tube 164 can rotate around the axis A of the relay pipe 162.

  As shown in FIG. 6, a pair of nozzle portions 164c protrudes downward from the lower surface of the horizontal portion 164a. The nozzle portion 164c is formed with a slit 164d extending in the longitudinal direction of the horizontal portion 164a (left and right direction in FIG. 6). When hot water is supplied to the relay pipe 162, hot water is jetted downward from the slit 164d. The

  Further, a small hole 164e is formed in the side surface of the nozzle portion 164c in a direction orthogonal to the major axis direction of the horizontal portion 164a (vertical direction in FIG. 5 and horizontal direction in FIGS. 6 and 7). The small hole 164e is formed on the side surfaces that are opposite to each other in the one nozzle portion 164c and the other nozzle portion 164c. When hot water is supplied to the relay pipe 162, hot water is ejected from the small hole 164e, and a force in a direction opposite to the direction in which the hot water is ejected (the white arrow direction in FIG. 5) is applied to the nozzle portion 164c. As a result, the nozzle tube 164 rotates around the axis A of the relay pipe 162 (in the direction of the solid arrow in FIG. 5).

  Further, as shown in FIG. 7, the vertical portion 164 b of the nozzle pipe 164 is movable in the vertical direction within the bearing portion 162 a of the relay pipe 162. A narrow tube 162b that passes through the vertical portion 164b and reaches the horizontal portion 164a is fixed to the upper end of the relay pipe 162. When hot water is supplied to the relay pipe 162, the hot water passes through the narrow tube 162b and the horizontal portion 164a. The nozzle tube 164 is pushed upward by the water pressure at this time.

  As shown in FIGS. 5 and 6, a pair of crests 162c and troughs 162d are provided at the upper end of the bearing 162a. The mountain parts 162c and the valley parts 162d are alternately arranged. A locking recess 162e is provided at the bottom of the valley portion 162d. In addition, a pair of locking projections 164f projecting radially from the cylindrical surface is formed on the vertical portion 164b of the nozzle tube 164. In a state where hot water is not supplied to the nozzle tube 164, as shown in FIG. 5, the locking projection 164f moves along the inclined surface formed between the peak portion 162c and the valley portion 162d, and finally locks. It reaches the recess 162e and stops. When hot water is supplied to the nozzle tube 164 from this state, the nozzle tube 164 is lifted as described above, the locking projection 164f rises from the locking recess 162e, moves to a position higher than the peak portion 162c, and the locking recess 162e The nozzle tube 164 rotates without interfering with the locking projection 164f.

  When the supply of hot water to the nozzle tube 164 is stopped by the control of the solenoid valve 120, the nozzle tube 164 descends and the locking projection 164f is again accommodated in the locking recess 162e. Since the locking recess 162e and the locking projection 164f are formed at an interval of 180 ° with respect to the axis A of the relay pipe 162, the horizontal portion 164a of the nozzle tube 164 is provided in the state where hot water is not supplied to the nozzle tube 164. The longitudinal direction of is always in a specific direction.

  Thus, in this embodiment, since the nozzle tube 164 rotates and sprays warm water toward the powder detergent P (FIG. 4) below, the upper surface of the powder detergent P deposited on the upper container 111 In addition, the hot water can be injected substantially uniformly.

  A mechanism for sending the cleaning liquid to the cleaning liquid discharge pipe 134 will be described below. As shown in FIG. 4, a mesh tube 168 is attached to the bottom opening 111b of the upper container 111 in which the powder detergent P is accommodated. The mesh tube 168 is a cylindrical member extending upward, and a large number of small holes are formed on the cylindrical surface. Since the small holes are sufficiently small, the powder detergent P hardly enters the inside of the mesh tube 168, and the powder detergent P does not move from the opening 111b of the upper container 111 to the lower container 112. On the other hand, the cleaning solution in which the detergent is dissolved in warm water passes through the small holes and moves to the inside of the mesh tube 168, moves down inside the mesh tube 168, and moves from the opening 111b to the lower container 112. As shown in FIG. 4, the bottom 111 a of the upper container 111 is formed in a mortar shape, so that most of the cleaning liquid does not stay in the upper container 111 and moves to the inside of the mesh tube 168. It has become.

  As shown in FIG. 4, since the relay pipe 162 passes through the inside of the mesh tube 166, the cleaning liquid supply apparatus 100 can be made more compact than the configuration in which the relay pipe 162 is provided outside the container. . Further, when the relay pipe 162 is inside the upper container 111 and outside the mesh tube 166, there is a possibility that the relay pipe 162 inhibits the flow of hot water or cleaning liquid and a part of the powder detergent P is hardly dissolved. However, in this embodiment, the flow of warm water or cleaning liquid is not hindered by the relay pipe 162.

  As shown in FIG. 4, the bottom 112 a of the lower container 112 has a downward slope toward the cleaning liquid discharge unit 132, and the cleaning liquid that has moved to the lower container 112 is guided to the cleaning liquid discharge unit 132. A cleaning liquid discharge pipe 134 is connected to the cleaning liquid discharge section 132, and the cleaning liquid moves to the cleaning water tank 30 through the cleaning liquid discharge pipe 134. The cleaning liquid discharger 132 is disposed at a position higher than the cleaning water tank 30, and the cleaning liquid moves to the cleaning water tank 30 by its own weight.

  Next, functions of the control unit 150 will be described. As shown in FIG. 1, a concentration sensor 152 for measuring the concentration of the cleaning liquid in the cleaning water is provided in the cleaning water tank 30. The detection result of the cleaning liquid concentration by the concentration sensor 152 is sent to the control unit 150 via the signal cable 154. The control unit 150 controls the opening and closing of the electromagnetic valve 120 based on the detection result of the cleaning liquid concentration in the cleaning water tank 30. Specifically, when the cleaning liquid concentration in the cleaning water tank 30 falls below a predetermined threshold value, the electromagnetic valve 120 is opened for a predetermined time to generate a cleaning liquid, which is sent to the cleaning water tank 30.

  Reference numeral 156 (FIG. 2) denotes a power cable for supplying drive power for driving the control unit 150 and the density sensor 152.

  Next, a structure for supplying the powder detergent to the container part 110 of the cleaning liquid supply apparatus 100 will be described. FIG. 8 is a side sectional view of the cleaning liquid supply apparatus 100. As shown in FIGS. 4 and 8, an opening 111 c for replenishing the powder detergent P is provided in the upper part of the upper container 111 of the container part 110. A container cover 113 for covering the opening 111c is provided in the opening 111c. When replenishing the container part 110 with the powder detergent P, the container cover 113 is opened and the powder detergent P is replenished from the opening 111c.

  A nozzle cover 114 is provided in the upper part of the upper container 111. As shown in FIGS. 4 and 8, the nozzle cover 114 is a long plate-like member, and is arranged so that its longitudinal direction is substantially parallel to the longitudinal direction of the nozzle tube 164 in a stationary state. Further, the nozzle cover 114 is bent in a mountain shape along the longitudinal direction thereof, and most of the powder detergent on the nozzle cover 114 when the powder detergent is introduced from the opening 111c is along the inclined surface of the mountain shape. It falls into the upper container 111. Further, since the upper portion of the nozzle tube 164 is covered with the nozzle cover 114 as described above, the detergent is not applied to the nozzle tube 164 when the powder detergent P is replenished.

  Further, as shown in FIG. 8, the container cover 113 is formed by connecting the first part 113a and the second part 113b with a hinge. The first portion 113a of the container cover 113 is rotatably supported on the upper end of the upper container 111 via a hinge. The hinge that supports the first portion 113a is arranged so that the hinge axis B faces the horizontal direction perpendicular to the longitudinal direction of the nozzle cover 114 (the direction perpendicular to the paper surface in FIG. 8). The hinge connecting the first part 113a and the second part 113b is also attached so that the hinge axis is parallel to the hinge axis B. Further, the slider 115 is connected to the tip of the second part 113b (on the opposite side to the position connected to the first part 113a) so as to be rotatable around an axis parallel to the axis B. The slider 115 can advance and retreat along the longitudinal direction of the nozzle cover 114. When the second portion 113b of the closed container cover 113 (solid line portion in FIG. 8) is pulled toward the axis B, the first portion The slider 115 moves toward the axis B while rotating 113a clockwise around the axis B in FIG. 8 and the second part 113b turning counterclockwise around the connecting portion with the slider 115 in FIG. Move on the cover 114. When the slider 115 moves to the vicinity of the axis B, the container cover 113 is fully opened, and most of the opening 111c of the upper container 111 is exposed (a broken line portion in FIG. 8). As described above, in the present embodiment, the container cover 113 is opened while the first portion 113a and the second portion 113b are bent with respect to each other at the connecting portion between the first portion 113a and the second portion 113b. Therefore, the container cover 113 can be opened and closed even when there is not enough space above the upper container 111.

  When the container cover 113 is opened and closed, the slider 115 moves while rubbing the upper surface of the nozzle cover 114. At this time, the powder detergent accumulated on the upper surface of the nozzle cover 114 is removed by the slider 115. It falls into the upper container 111.

  As described above, in the cleaning liquid supply apparatus 100 of the present embodiment, the nozzle cover 114 prevents the detergent from being applied to the nozzle tube 164 when the detergent is replenished, and the powder detergent accumulated on the upper surface of the nozzle cover 114 is removed. When the container cover 113 is opened and closed, it can be removed by the slider 115.

  Next, the flow rate adjustment valve 166 (FIG. 4) used in the cleaning liquid supply apparatus 100 of this embodiment will be described. FIG. 9 is a cross-sectional view of the flow rate adjustment valve 166 of the present embodiment. As shown in FIG. 9, the flow rate adjustment valve 166 includes a valve body 166 a and a coil spring 166 b housed inside the relay pipe 162. The coil spring 166b has an upper end engaged with a stepped portion 162f provided on the relay pipe 162, and the other end engaged with a valve body 166a. When the valve body 166a moves upward, the stepped portion 162f and the valve body 166a are engaged. And a repulsive force in a direction to push the valve body 166a back downward is applied to the valve body 166a.

  A concave portion 166c that is concave upward is formed at the lower end of the valve body 166a. Further, an opening 166d for escaping warm water is provided on the side surface of the recess 166c. The hot water supplied from the hot water supply pipe 122 enters the recess 166c to push up the valve body 166a, and moves out of the opening 166d to the downstream side of the relay pipe 162 through the gap between the relay pipe 162 and the valve body 166a. .

  As shown in FIG. 9, the valve body 166a is a cylindrical member whose diameter decreases toward the top, and the diameter of the tip of the valve body 166a is that of the downstream portion 162g of the relay pipe 162 on the downstream side of the stepped portion 162f. When the valve body 166a is pushed up by the hot water pressure, the valve body 166a reduces the cross-sectional area of the flowing dew through which the hot water flows and the pressure loss increases. The water pressure (secondary pressure) can be suppressed. As described above, the valve body 166a is biased by the coil spring 166b, and as the upstream water pressure (primary pressure) increases, the cross-sectional area of the flow path through which the hot water flows is further reduced and the pressure loss increases. In this embodiment, if the solenoid valve 120 (FIG. 2) is in an open state, the flow rate of hot water flowing through the relay pipe 162 (that is, supplied to the nozzle pipe 164) is within a predetermined range regardless of the primary pressure. The shape of the valve body 166a and the spring constant of the coil spring 166b are set so as to be within the range.

  Next, the structure of the mesh tube 168 will be described. FIG. 10 is a perspective view of the mesh tube 168 of the present embodiment. As shown in FIG. 10, the mesh tube 168 has a first part 168a and a second part 168b that are substantially semi-cylindrical. The first part 168a and the second part 168b are joined together at one edge extending in the major axis direction, and the second part 168b is rotated in the direction of the arrow in the figure around the coupling part 168c, By connecting the edges on the other side of the first part 168a and the second part 168b, a substantially cylindrical mesh tube 168 (broken line part in the figure) is formed. In addition, the nail | claw and nail | claw engaging hole for connecting both are formed in the edge part of the other side of the 1st part 168a and the 2nd part 168b.

  The mesh tube 168 of this embodiment is made of a resin material such as nylon or polyester. In the present embodiment, as described above, since the mesh tube is expanded into the first portion 168a and the second portion 168b, the mesh tube having a large number of small holes formed on the surface is easily formed by injection molding. Is possible.

  In the present embodiment, the flow rate of the hot water supplied to the nozzle pipe 164 by the flow rate adjustment valve 166 is limited to a predetermined range, but the present invention is not limited to the above configuration, and the nozzle pipe 164 It is good also as a structure which does not adjust the flow volume of the hot water supplied.

  In the present embodiment, a pair of nozzle portions 164c is formed in the nozzle tube, but the present invention is not limited to this configuration, and only one nozzle portion 164c or three or more nozzle portions 164c are provided. It is good also as composition which has. The nozzle portions 164c may not be provided symmetrically, and the number of the nozzle portions 164c on one side may be different from the number of the nozzle portions 164c on the other side.

  In this embodiment, the nozzle tube 164 having the nozzle portion 164c formed at the bottom is rotated to supply hot water to the powder detergent P in the upper container 111 substantially evenly. Is not limited to the above configuration, and the nozzle tube 164 is swung, or a large number of stationary nozzles are arranged inside the upper container 111 and outside the mesh tube 166 so that warm water is supplied to the powder detergent P substantially evenly. It is good also as a structure to supply.

  Further, the upper container 111, the mesh pipe 168, the relay pipe 162, and the nozzle pipe 164 are removed, a nozzle is attached to the upper end of the hot water introduction pipe 112b, and a vacuum breaker is attached in the middle of the hot water supply pipe 122. Instead, by attaching a cartridge filled with powder detergent, it is possible to provide a type of cleaning liquid supply device that generates a cleaning liquid by spraying warm water from below into the detergent filled in the cartridge.
