JPS60120141A - Variable direction type discharging port for bath boiler - Google Patents

Abstract

PURPOSE:To prevent the loss of amount of heat upon keeping the temperature of bath and improve efficiency upon heating hot-water by a method wherein the bath boiler is equipped with the variable direction type hot-water discharging port. CONSTITUTION:The discharging port is consisting of a curved pipe 1 and a spring 2. The spring 2 is inserted into the discharging port which is equipped conventionally and whereby the pipe 1 is rotatable about the discharging port. The discharging port is faced upward upon heating the water of bath. In this case, the convection of the hot-water is promoted by chimney effect possessed by the pipe 1, and the efficiency of hot-water heating may be improved. The discharging port is faced downward upon keeping the temperature of the bath to locate the port at a position lower than a suction port 3. In this case, reverse flow becomes hard to be generated and the loss of amount of heat may be prevented. If it happens to ignite the bath boiler by mistake under this condition, the effiency of heating the hot-water is deteriorated but it never causes to heat an empty boiler.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a variable-direction oven (11) which prevents loss of heat when keeping the stove warm and improves efficiency when boiling water.

In conventional wind stoves, hot water convection occurs in the opposite direction to the N13 direction when keeping the water warm, resulting in a loss of heat.

In other words, the iJA I that flowed back into the Furo Kama from the above υM Toriguchi
It is effectively cooled by the heat exchanger in the k-air stove, becomes heavier, and is discharged as cold water from the lower intake port.

For this reason, the amount of heat lost when keeping warm in the wind stoves in homes across Japan is extremely large. In order to prevent this backflow, it is possible to install a valve at each outlet, but this is not common due to the cost and the danger of dry boiling.

The present invention was invented to overcome the following two drawbacks, and will be explained below with reference to the drawings.

This directionally variable discharge port consists of a bent vibrator l and a spring 2, as shown in Figure 1. By inserting the spring section into a conventional outlet, this pipe 1 can freely rotate around the outlet.

When heating the stove, the outlet should face upward as shown in the second diagram. In this case, the chimney effect of the pipe promotes the convection of hot water, increasing the efficiency of boiling water.

When keeping the furnace warm, place the exhaust port down by 1 bl as shown in the third figure.
+: I, inhalation 1". In this case, the above-mentioned backflow is less likely to occur, and loss of heat can be prevented. Also, if you accidentally ignite the kettle in this condition, the efficiency of boiling the water will decrease and you will not be able to boil it dry.

This variable-direction outlet can be installed regardless of the type of fuel or whether it is new or old, as long as it has an outlet and an inlet.

The same effect can be obtained by using this directionally variable type U1 output [1 for inhalation [I, facing downward when boiling water, and facing downward when holding water]].
