A magnet 42 is fixed to the rotary arm 41, and a reed switch 43 is fixed to the support arm 39 so as to face the magnet 42. The drain tank 31 is filled with water and sinks downward. Then, the rotation arm 41 rotates downward to move the magnet 42 away from the reed switch 43. Based on this, the reed switch 43 performs a switching operation to detect fullness of the drain tank 31.

Next, the operation of the above configuration will be described. It is now assumed that the carriage 5 is housed in the support base body 4 and the water storage tank 15 is sufficiently filled with water (see FIG. 2). Here, if the automatic tea dispenser is frequently used and the water level in the hot water storage tank falls below a predetermined water level, the pump motor 21 is energized based on a signal from the automatic tea dispenser. As a result, the water supply pump 20 is operated, and fresh water is supplied from the water receiving portion 14 to the hot water storage tank of the automatic tea dispenser 2 through the water supply pump 20, the connecting pipe 22, and the water supply hose 25 in this order. Then, when a predetermined amount of water is supplied to the hot water storage tank, the pump motor 21 is cut off based on the signal from the automatic tea supply machine, and the supply of water to the automatic tea supply machine is stopped.

When the water supply from the water storage tank 15 to the automatic tea dispenser 2 is repeated as described above, the water in the water storage tank 15 becomes empty, and the automatic tea dispenser cannot be supplied with water. The hot water storage tank in the automatic tea dispenser becomes dry. Then, a water level sensor (not shown) provided in the hot water storage tank is activated to turn on the water shortage display lamp provided on the operation panel of the automatic tea supply machine 2. As a result, the administrator of the automatic tea dispenser 2 will replenish the water storage tank 15 with water, as it is known that the water storage tank 15 has become empty.

First, the front door 6 of the water storage unit is pulled toward you. Then, the front door 6 separates from the magnet catch 4a of the support base body 4 and is pulled out to the front together with the carriage 3. When the front door 6 is slightly opened, the one-touch joint insertion portion 24b of the water supply hose 25 is removed from the receiving portion 24a to separate the water supply hose 25 from the carriage 5. Then, when the front door 6 is further pulled out to the front, the casters 7 on the front side of the carriage 3 come into contact with the floor surface F in order, and the carriage 3 is completely pulled out from the inside of the support base body 4 to support the main body 4 of the support base. To the separated state (see FIG. 1). Here, since the water tank 15 is still set in the trolley 3, it is sufficient to push the trolley 3 to the water field with the water faucet without removing the water tank 15. Then, at the water place, the water storage tank 15 may be removed from the water receiving portion 14, the lid 17 of the water storage tank 15 may be removed, and water may be supplied. Immediately after filling the water storage tank 15 with water, the water storage tank 15 in a full state is immediately set in the water receiving portion 14, and the trolley 3 is pushed again in a state of being loaded on the trolley 3 to return to the installation position of the support base 1, Push the carriage 3 into the support base body 4.

When the carriage 3 is further pushed into the support base body 4, the carriage 3 is completely supported by each support roller 10, and is stored in the support base body 4 in a state of being lifted from the floor surface F. Since the leaf springs 11a attached to both left and right sides of the carriage 3 come into contact with both guide walls 9a of the support body 4 in the process of pushing the carriage 3 into the support base body 4 to receive elastic force from both left and right sides. The carriage 3 is guided in the center of both guide walls 9a without rattling. Further, immediately before the carriage 3 is completely housed in the support base body 4, the position guide rod 30 on the side of the carriage 3 is inserted into the position guide receiver 28 on the support base body 4 side, so that the positioning action of both is performed. As a result, the carriage 3 is always guided to the regular position. As a result, the magnet plug 27 and the magnet socket 29 are securely connected, and the electrical connection is surely made.

As described above, according to the present embodiment, when the water tank 15 needs to be replenished with water, the trolley 3 is pulled out from the support base body 4 and pushed to the water field, where water is replenished. After that, with the water tank 15 loaded on the trolley 3 again, the trolley 3 is pushed back to the original position, and the trolley 3 is pushed into the support base body 4 to complete the water supply. Therefore, it is not necessary to lower the water tank 15 that has been filled with water and becomes heavy to the place where the support base 1 is installed from the water field, and the water replenishment work is significantly simplified. Moreover, in this embodiment, the three support rollers 10 are arranged in the front-rear direction on the guide wall 9a of the support base body 4 so that the carriage 5 moves while the guide member 11 rotates the support rollers 10. Therefore, the dolly can be stored smoothly. In particular, even if the caster 7 is not lifted, the guide member 11 rides on the support roller 10 along the inclined surface 11b, so that the carriage can be stored easily. Further, in this embodiment, particularly, leaf springs 11a are attached to both left and right sides of the bogie 5, and when the bogie 5 is housed in the support base body 4 of the bogie 5, the bogie 5 slides on the guide wall 9a by the elastic force of the leaf spring 11a. Because of the contact structure, when the carriage 5 is stored in the support base body 4, the carriage 5 is stored in the fixed position between the guide walls 9a without rattling due to the elastic force of each leaf spring 11a. Become. For this reason, the connection between the magnet plug 27 and the magnet socket 29 is ensured, and the occurrence of electrical contact failure can be prevented in advance.

In the above embodiment, the water supply pump 20 and the pump motor 21 are arranged on the dolly 5. However, the invention is not limited to this, and the water supply pump 20 and the pump motor 21 are not included in the support base body 4. It may be configured such that the trolley 5 is mounted on the side, the trolley 5 is housed in the support pedestal body 4, and the water supply passage from the water supply pump 20 is connected to the water receiver 14 on the trolley 5 side. Further, although the support roller 10 is attached to the support base body 4 side, it may be attached to the carriage 5 side.

Besides, the present invention is not limited to the embodiments described above and shown in the drawings.
