Abstract

PURPOSE:To contrive the improvement of flexibility at the installation and the improvement of burning efficiency by a method wherein a burning chamber and a heat exchanging chamber are connected in parallel with connecting openings, and fitting openings of each burner and exhausting cylinder are arranged in left and right symmetrical manner, then the burner and exhausting cylinder are made interchangeable fitting. CONSTITUTION:A burning chamber A and a heat exchanging chamber B are provided with respective fitting openings 3, 4 for each burner 1 and exhausting cylinder 2 in left and right symmetrical manner, both chambers A, B are installed by connecting in parallel with connecting openings C. By such a structure, even when the directional arrangement of a heater is required, the problem can be easily solved by installing after changing of the fitting location of the burner 1 and the exhausting cylinder 2. Further, outer cases 1', 2' of the burner 1 and the exhausting cylinder 2 are connected with a passage 5. By introducing a part of the exhaust gas to the burner 1, the burning temperature is lowered, accordingly, the generating quantity of NOX can be decreased.

Description

[Detailed Description of the Invention] This invention mainly relates to a bathtub, and it is possible to alternately change the mounting position of the burner and exhaust pipe depending on the installation location of the bathtub and the location of the pot, and to increase the P burning efficiency. It is characterized by:

To explain the manufacturing structure, there is a combustion chamber A, a heat exchange chamber B. ! : are installed in parallel through the connection port C, and the installation ports 3 and 4 of the burner 1 and the exhaust pipe 2 are provided in symmetrical positions in each of the combustion chamber B. This relates to the structure of a bathtub or the like in which cylinders 2 can be attached alternately.

In the figure, reference numeral 5 denotes a passageway that completely communicates between the burner 1 and the outer frames 1' and 2' of the exhaust pipe 2, allowing a portion of the exhaust gas to be guided to the burner side. 6 and 6' are connection ports that connect the bath pot and the tub, 7 is a nozzle that is connected to the oil pipe 8, 9 is a spark plug provided close to the nozzle nozzle 7, and 10 is a combustion port that is provided opposite the nozzle nozzle 7. Flame expansion plate, 1] is the motor for the blower fan 12,
Reference numerals 13 and 14 are inner and outer tubes for forming the combustion chamber A and the heat exchange chamber B into a double tube structure so as to constitute an ice chamber D when the present invention is applied to a bathtub. Reference numeral 15 denotes a leg provided at the lower part of the combustion chamber A' and the heat exchange chamber B.

Conventionally, this type of bathtub had a structure in which the burner was installed either horizontally, downwardly, or upwardly relative to the combustion chamber, and the exhaust pipe was installed in various positions.

For this reason, depending on the installation position of the bucket or kettle, the directionality of the appliance was affected, and installation was often impossible.

In order to eliminate such drawbacks, in the present invention, the combustion chamber and the heat exchange chamber are provided in parallel, and the respective mounting ports 3 and 4 are made symmetrical, so that even if directionality is required for the installation of the pot, the burner and exhaust can be easily connected. This can be solved by simply changing the mounting position with respect to the cylinder. Further, if the burner and the exhaust pipe are provided at the upper part of each container as shown in the figure, the directionality of the front damage is not required, and it is sufficient to replace only the left and right sides. Although the actual drawing shows the case of a bathtub, it can also be used as a boiler or a heater, and has a wide range of applications. In addition, if the burner 1 and the outer frames 1' and 2' of the exhaust pipe 2 are connected through the passage 5 and all of the exhaust gas is guided to the burner 1 side, the oxygen in the smoldering air supplied to the burner can be reduced. Since the amount is slightly reduced and the combustion temperature is lowered, the amount of Nox generated such as No. 4 is symmetrical, so the passage 5, the burner 1, and the exhaust pipe 2
If these are integrally formed, it is possible to satisfy all of the above characteristics.

As described above, the present invention has excellent features and has a wide range of applications.
