The can body of a conventional semi-storage type water heater is, for example, made in 1983-
As shown in Publication No. 154454, a hot water supply tank, a water intake tank having a smaller capacity than the hot water supply tank and provided below the hot water supply tank, a large number of heat absorption pipes provided with fins connecting both tanks, and the ends of both tanks. Conventionally, in such semi-hot water storage type cans, a heater is inserted into the water tank, and when the outside temperature drops to around freezing temperature, the heater is energized.

However, with this conventional antifreeze device, when the outside temperature drops extremely and the heating capacity of the heater is insufficient, the fins and the vicinity of the hot water tap tank with a large surface area, which are particularly susceptible to the influence of outside temperature, may be at low temperatures. There are problems such as freezing,
In addition, in order to prevent freezing, it was necessary to use a large-sized heater with a large capacity, which resulted in problems such as increased product cost and power consumption. A structure of an instantaneous can body has been disclosed in which a circulation circuit is formed by a bypass path and hot water heated by a heater is circulated to prevent freezing, but semi-hot water storage type cans are heated by heating a burner in the first place. The water in the heat absorption pipe reaches the hot water outlet tank, the low temperature hot water in the hot water outlet tank returns from the return pipe to the water intake tank, and water is supplied from the water intake tank to the heat absorption pipe, keeping the ice in the tank at an appropriate temperature. Regarding the freezing prevention of this type of semi-hot water storage type can, there has not yet been found anything that generates an effective circulating flow by heating the heater.

In view of the above-mentioned problems with the conventional freezing prevention device for semi-storage type water heaters, the present invention is designed to effectively prevent freezing in semi-storage type water heaters by generating circulating flow inside the can by heating the heater. The purpose is to provide a prevention device.

That is, the heater is inserted into the water inlet tank from one side surface on the return pipe side of the water inlet tank, and the upper part of the water inlet tank on the heater side and the side part of the outlet tank on the side diagonally to the heater are inserted. A bypass pipe with an upward slope is provided on the side of the communicating hot water tank.

With this structure of the present invention, the hot water heated by the heater is sent from the heat absorption pipe to the area near the outlet of the hot water tank - the part of the zone that is most likely to freeze, via the bypass pipe, and the hot water is also released from the return pipe. As hot water flows into the tank, the cold water in the heat absorption pipe flows into the water inlet tank, is heated by the heater, and then flows into the hot water tank through the bypass pipe and return pipe, creating a circular flow, which freezes extremely efficiently. Even a small, small-capacity heater can sufficiently prevent freezing.
