The insertion port 11b is always covered with a lid 11c. A float switch 11d that determines the upper limit water level of the saturated salt water S1 in the tank body 11a and a water level detection sensor 11e that determines the lower limit water level of the saturated salt water S1 in the tank body 11a are disposed in the tank body 11a. Yes. Further, the saturated salt water preparation tank 11 includes an overflow line 11f for draining an excessive amount of the saturated salt water S1 in the tank body 11a, and a circulation line 11g for circulating the saturated salt water S1 in the tank body 11a. ing. A circulation pump 11h and a conductivity meter 11i with a thermometer are interposed in the middle of the circulation line 11g.

  The first water supply line 12 functions to supply the saturated salt water prepared in the saturated salt water preparation tank 11 to the ice making water storage tank 21 of the ice making machine 20, and the circulation pipe constituting the saturated salt water preparation tank 11. It is connected in the middle of the road 11g. Thereby, a part of the saturated salt water flowing in the circulation pipe 11 g can be supplied to the ice-making water storage tank 21 through the first water supply pipe 12. The second water supply line 13 functions to supply city water as dilution water to the ice making water storage tank 21 and is connected to a city water supply source, for example, a tap water supply source. The third water supply line 14 functions to supply city water into the tank body 11 a of the saturated salt water preparation tank 11, and is connected in the middle of the second water supply line 13.

  The amount of city water supplied to the tank body 11a of the saturated salt water preparation tank 11 by the third water supply pipe 14 is controlled by an opening / closing valve 14a linked to the operation of the float switch 11d.

The storage tank 21 is taken in as a component tank of the salt water preparation device. For this reason, the salt water preparation device 10 according to the present invention is configured in combination with an ice making machine 20 that uses salt water as ice making water S2, and is greatly reduced in size as compared with the conventional salt water preparation device. Water supply means such as a water supply pump for supplying ice making water prepared in the salt water preparation tank to the ice making water storage tank, and control means for controlling the water supply means, which are indispensable in the salt water preparation device, are unnecessary. Thus, the configuration of the apparatus can be greatly simplified.
