Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dilution unit structure of a diluting device which is provided with a diluting chamber for diluting a liquid to be diluted such as a detergent undiluted liquid with tap water, and which is configured to be supplied by tap water pressure.

[0002]

[Prior art]

 In the above diluting device, conventionally, as shown in FIG. 5, the water supply port 16 of the diluting chamber 7 was formed in the lateral side wall portion 7b of the diluting chamber 7.

[0003]

[Problems to be solved by the device]

 In this type of diluting device, since water is supplied to the diluting chamber by tap water pressure during use, the diluting chamber is connected to the tap water channel through the water supply hose. Therefore, it is preferable that the liquid to be diluted supplied to the diluting chamber and the diluting liquid formed in the diluting chamber do not flow back to the tap water channel side. Conventionally, in order to prevent the diluted liquid from flowing back to the water supply channel side, as shown in FIG. 5, the lower end of the water supply port 16 of the dilution chamber 7 is located at a higher level than the liquid level of the dilution chamber 7. Therefore, it is necessary to make it difficult for the diluting liquid to flow out from the water supply port 16, so that the arrangement level of the water supply port 16 needs to be set to a high level, and as a result, the proportion of the diluting liquid that remains in the diluting chamber is divided. Had to prepare a large volume for the diluting chamber, and there was a problem that the diluting chamber became large. Furthermore, the water from the water supply port will drop from a high-level location.For example, when diluting the undiluted detergent solution, blistering of the diluted diluent in the diluting chamber tends to occur due to the impact of dropping the water supply. Was becoming. The purpose of the present invention is to make it possible to reduce the size of the diluting chamber and to prevent the trouble due to the drop impact of the water supply from being structurally simple, while avoiding the reverse flow of the diluting liquid to the water supply channel side. To do.

[0004]

Means for Solving the Problems The structure of the diluting portion of the diluting device according to the present invention is the same as the one described at the beginning in order to achieve the object. The diluting chamber is provided with a water receiving surface that is located between the diluting chamber and the water, and receives the water from the water supply port and then flows it down.

[0005]

[Action]

 Since the water supply port is located on the upper wall, the height of the water supply port from the diluting liquid surface can be controlled so that the diluting liquid can flow into the water supply port while lowering the overall height of the diluting chamber as compared with the conventional system where the water supply port is located on the side wall. The height can be easily avoided. Furthermore, the water supply port is arranged at a high level so that the inflow of the diluting liquid can be easily avoided, and in order to supply water from a high level, the supply water is received by the water receiving surface and gently flows down into the diluting chamber to become the diluting water. Drop impact is less likely to occur.

[0006]

[Effect of device]

 Since the water inlet can be arranged at a relatively high level, it has become possible to use it while making it difficult for the diluting liquid to flow back from the water inlet to the tap water channel side. In comparison, the diluting chamber can be made compact with a relatively low height for easy handling, and further, the action of the water receiving surface makes it difficult for bubbling to occur. I was able to make it advantageous.

As shown in FIG. 3, a stock solution storage unit including a pair of stock solution tanks 3 and 4 is provided at the upper inside of a diluter case 2 having a front lid 1 swingably opened and closed. The diluting section provided with the diluting chamber 7 connected by the liquid supply passages 5 or 6, the water supplying passage 8 connected to the upper portion of the diluting chamber 7, and the take-out pipe 9 connected to the bottom of the diluting chamber 7 is used as the diluting device case 2 described above. And an electromagnetic water supply valve V1 or V2 in the liquid supply passages 5 and 6, and an electromagnetic water supply valve V3 in the water supply passage 8, respectively. , V2 and electromagnetic water supply valve V3 are automatically controlled by a dilution control mechanism 10 provided inside the front lid 1 to form a dilution device. This diluting device is used to obtain a diluting solution obtained by diluting a stock solution of detergent with tap water to a concentration suitable for use when washing walls, windows, floors, furniture, etc. It is configured as follows. The diluting device case 2 is attached to the wall surface so that the entire device is suspended and supported for use. That is, by suspending and supporting, the undiluted solution of the detergent can be naturally flowed from the undiluted solution storage portion, and the undiluted solution can be supplied to the dilution chamber 7. Further, the diluting liquid can be naturally discharged in the diluting chamber 7, and the diluting liquid can be taken out.

As shown in FIG. 3, the undiluted solution tanks 3 and 4 are prepared by dropping the undiluted solution container 11 or 12 in an inverted state from an upward opening having a detachable lid 3a or 4a to drop the undiluted solution solution A. Alternatively, it is configured to store B. That is, when the undiluted solution container 11 or 12 is dropped in an inverted state, the support base 14 provided at the bottom of the undiluted solution tank 3 or 4 holds the undiluted solution container 11 or 12 at the liquid outlet 11a or 12a. The vertical wall of the stock solution tank 3 or 4 receives and acts on the peripheral wall of the stock solution container 11 or 12 so that the stock solution tank 3 or 4 accommodates and holds the stock solution container 11 or 12 in an inverted state. When the container is accommodated, the lid breaking cylinder 13 provided on the support 14 pierces the liquid outlet 11a of the stock solution container 11 or the resin lid of the solution outlet 12a of the stock solution container 12 to break the inside of the stock solution container 11 or 12. The inside of the stock solution container 11 or 12 communicates with the inside of the stock solution tank 3 or 4 through the inner passage of the lid breaking cylinder 13 and the inner passage 14a of the support base 14, The undiluted solution A or B of the internal detergent flows out to the bottom of the tank of the undiluted solution tank 3 or 4 and stays there by spontaneous outflow.

The diluting chamber 7 is formed by a container having a bottom wall portion 7a, a side wall portion 7b and an upper wall portion 7c each having a shape as shown in FIGS. The water supply port 16 of the dilution chamber 7 is formed in the upper wall portion 7c by the end of the water supply passage 8, and the first liquid supply port 17 of the dilution chamber 7 is formed by the end portion of the liquid supply passage 5 in the upper wall portion 7c. The second liquid supply port 18 of the dilution chamber 7 is formed in the upper wall portion 7c by the end of the liquid supply passage 6. When the electromagnetic liquid supply valve V1 is opened, the internal detergent stock solution A of the stock solution tank 3 naturally flows down to the first liquid supply port 17 of the dilution chamber 7 through the supply liquid path 5, and the electromagnetic liquid supply valve When V2 is opened, the undiluted detergent solution B in the undiluted solution tank 4 naturally flows down through the supply solution passage 6 to the second supply port 18 of the dilution chamber 7. A hose joint 8a is provided at the end of the water supply passage 8 opposite to the diluting chamber 7, and the water supply hose 15a from the water supply source 15 is connected to the hose joint 8a to open the electromagnetic water supply valve V3. When operated, tap water W from the water supply source 15 flows into the water supply passage 8 by tap water pressure, so that the water supply passage 8 is configured to supply the tap water W from the water supply source 15 to the water supply port 16 by tap water pressure. There is. The water supply passage 8 is provided with the constant flow rate control valve V4, and when the tap water pressure is equal to or higher than the set water pressure determined by the constant flow rate control valve V4 at the time of water supply, even if the tap water pressure changes, the water pressure to the water supply port 16 is increased. Since the amount of water supply per unit time is made substantially constant by the action of the constant flow rate control valve V4, and when the time for opening the liquid supply valve V1 or V2 within the unit time is determined, To properly control the electromagnetic liquid supply valves V1, V2 and the electromagnetic water supply valve V3 by determining the amount of the undiluted detergent solution A or B flowing down to the first liquid supply port 17 or the second liquid supply port 18 per unit time. Then, the detergent stock solutions A and B and the tap water W flow into the diluting chamber 7 in a predetermined amount, and the diluting chamber 7 dilutes the detergent stock solutions A and B with tap water W to a concentration determined by the inflow amount of the diluted detergent solution. create. The take-out pipe 9 is attached to the bottom wall portion 7a of the dilution chamber 7. The inside of the diluting chamber 7 communicates with the atmosphere through the gap between the upper wall portion 7c and the bottom wall portion 7a and the side wall portion 7b, and the liquid inside the diluting chamber 7 naturally flows out from the take-out pipe 9, A take-out hose 19 is connected to the take-out pipe 9, and the take-out hose 19 takes out and collects the diluted detergent solution from the diluting chamber 7 into a receiving container or the like.

The dilution control mechanism 10 is provided with push button type operation switches 21 to 26 as shown in FIG. 4, and a predetermined amount of a detergent diluting liquid of a predetermined type is taken out by pressing the operation switches 21 to 26. I am doing it. That is, 21 to 23 of the operation switches 21 to 26 are used to select the type of the diluted detergent solution to be taken out. The diluted detergent solution is prepared by diluting only the undiluted detergent solution A, the diluted detergent solution is prepared by diluting only the undiluted detergent solution B, and the detergent. This is to select which of the diluted detergent solutions obtained by diluting both the stock solutions A and B should be taken out. 24 to 26 of the operation switches 21 to 26 are for selecting the amount of the diluting detergent liquid to be taken out and for selecting which of 400 ml, 2000 ml and 5000 ml to be taken out. That is, one of the operation switches 21-23 and one of 24-26 are operated. Then, the dilution control mechanism 10 automatically sets one or both of the detergent stock solutions A and B as dilution target stock solutions based on the information from the operation switches 21 to 26, and takes out 400 ml, 2000 ml, or 5000 ml. In addition to setting the amount, set the opening control target time to operate the electromagnetic liquid supply valves V1, V2 and the electromagnetic water supply valve V3 to open, and a predetermined amount of the detergent stock solutions A, B and tap water flow into the dilution chamber 7. At the same time, the opening / closing control of the electromagnetic liquid supply valves V1 and V2 and the electromagnetic water supply valve V3 is performed so that the set amount of the diluted liquid flows out from the dilution chamber 7. The switch 27 shown in FIG. 4 is a power switch, and the lamp 28 is a power lamp.

The diluting chamber 7 is provided with the water receiving table 29, and the upper plate portion of the water receiving table 29 forms the water receiving surface 30 for the water supplied from the water supply port 16 so that the diluting liquid is supplied to the water supply passage 8. The diluting liquid can be taken out while preventing backflow and avoiding foaming in the diluting liquid inside the diluting chamber 7. That is, although the diluting liquid stays in the diluting chamber 7 due to the difference between the amount of water supplied to the diluting chamber 7 through the water supply passage 8 and the outflow amount of the take-out pipe 9 of the diluting chamber 7, the accumulated diluting liquid remains at the water supply port. The water supply port 16 is arranged at a high position relatively distant from the indoor bottom surface 7d of the diluting chamber 7 so as not to easily enter the water supply passage 8 from 16. The water receiving surface 30 is arranged between the level at which the indoor bottom surface 7d is located and the arrangement level of the water supply port 16. As a result, even if the liquid level of the staying diluent is at a lower level than the water receiving surface 30, the water receiving surface 30 does not drop the water from the water supply port 16 directly into the staying diluent. Allow to flow down to Retention Diluent. As a result, the water supplied from the water supply port 16 drops as quietly as possible so that the staying diluted liquid in the diluting chamber 7 is less likely to be impacted. The water receiving table 29 is composed of an upper plate portion forming a water receiving surface 30 and a pair of leg plate portions 29a, 29a supported by the inner bottom surface 7d of the diluting chamber 7, and the diluting liquid retained in the diluting chamber 7 It is configured so that it can flow out to the take-out pipe 9 through between the leg plate portions 29a. Instead of the water receiving stand 29 having this shape, a water receiving stand configured to be installed over the side wall portion 7b of the dilution chamber 7 is adopted, or is configured to be suspended from the upper wall portion 7c of the dilution chamber 7. A water pedestal may be adopted and implemented.

[Other Embodiments] A diluter is configured to dilute three or more types of detergent stock solutions or a single type of detergent stock solution with tap water, or a fertilizer stock solution is diluted in addition to the detergent stock solution to prepare a liquid fertilizer. The present invention can be applied to the case where the diluting device is configured so as to be manufactured. Therefore, these undiluted stock solutions are simply referred to as dilution target solutions A and B.
