Abstract

PURPOSE:To obtain high thermal efficiency, as well as to accurately detect the temperature of the water in a bathtub, by connecting one ends of a lower circulation pipe, of a thermister, and of a drum pipe to the lower chamber of a drum 'B', respectively, which is separated from an upper chamber by a bulkhead, and by connecting the other ends of a fin pipe and a drum pipe to a drum 'A'. CONSTITUTION:A drum 'B8' is divided into the upper and the lower, two chambers by a bulkhead 9. One ends of a hot water feed pipe 14, of an upper circulation pipe 10, and of a fin pipe 12 are respectively connected to the upper chamber 8a of a drum 'B8', and one ends of a lower circulation pipe 11, of a thermister 15, and of a drum pipe 13 are respectively connected to the lower chamber of it. Besides the other ends of a fin pipe 12 and of a drum pipe 13 are respectively connected to a drum 7. With such an arrangement, the fed warm water is prevented from being mixed with cold water before it is heated by a heat exchanger, when feeding of warm water and after-heating are performed at the same time. The temperature of the water in a bathtub can be detected accurately by a thermister, and high thermal efficiency can be obtained in a heat exchanger as well.

Description

[Detailed description of the invention] 3. An IP that explains in detail the 1st month of January? , -Industry I- +l group I misfire in January 1-Related to heat exchangers such as gas heaters and bathtubs.

BACKGROUND OF THE INVENTION In recent years, heat exchangers have been developed that have a reheating function and an easy-to-heat function.

While referring to the drawings below, the child series 7'? An example of a conventional heat exchanger will be explained below.

Fig. 3 (:1) is a cross-sectional view of a conventional heat exchanger. End, open sound of two drums 2 F'l: Mc.

A drum pipe 4 connects the two drums 2. Five single pipes are connected to the air supply via connecting pipes and solenoid valves (not shown).

6 is a thermistor.

J? Regarding the heat exchanger configured as shown in 1-,
Below, I will explain the operation in 1).

11. ,! When the water is poured into the drum 2, the ti1 (water U1 fin pipe 3, drum pipe 4, drum 2, circulation pipe 1
At the minute-OL, the bathtub connected to the circulation pipe 1 is connected to the bathtub connected to the circulation pipe 1.Thermistor 6 detects the temperature and the temperature of the hot water is controlled by Mi control 17/slip reheating. If ('', send that signal.

Problems to be solved in Solution 2 (7) However, in a configuration like 11, if pouring and reheating are performed at the same time, the poured d14 water and the fin pipe 3 Mix the water in the bathtub that has been circulated by combustion and use the thermistor 6 to accurately measure the water in the bathtub +711
'l or not detected. However, the problem was that the Al1 water, which had been heated to 41M, would be heated to 111 degrees, resulting in poor thermal efficiency.

In view of the above-mentioned problems, the present invention prevents hot water that has not been poured from mixing with water before it is heated by a heat exchanger, accurately detects the water temperature inside the bathtub with a thermistor, and
The purpose is to provide a heat exchanger that can achieve high thermal efficiency.

Problem (Y-Means for Solving 11) In order to solve the problem, the heat exchanger of the present invention has the following steps:
Drum A, drum B divided into two upper and lower chambers by a UJ board, 11 circulation pipe and pouring pipe connected to the separated upper chamber of drum B, and drum B separated from each other. The lower circulation pipe and thermistor connected to the lower chamber, and the separation of drum A and drum B. Place 11"゛I"12. Dora! , A and drum B

It is separated into a and 8b. 10Uj is a ring pipe connected to the ten rooms 8a/ξ-1 part i11'i, and 11 is a lower circulation pipe connected to the lower room 8b, each of which is connected to a bathtub. Reference numeral 12 denotes a fin pipe having a plurality of fins, where 1' heat exchange is performed and which connects the upper chamber 8a of the drum B8 and the drum A7.

There are several thermistors placed in the lower chamber 8b.

The operation of the heat exchanger configured as described above will be described below with reference to FIGS. 1 and 2.

FIG. 2 is an assembly diagram of an embodiment of a gas hot water bath system IT using the heat exchanger of the present invention. Delivery heat exchanger 16
The heated water enters the heat exchanger 19 of the present invention via the solenoid valve 17 and the connecting pipe 18. When reheating, natural circulation passes through the water in the bathtub, the lower circulation pipe 11, the lower chamber 8b of the drum 8, the drum pipe 13, and the drum 7, and is heated by the fin pipe 12, and then heated again to the drum 8. +r<l(Room 8 a 4r,

As mentioned above, according to the case of Honjikan I7, tl is 1-1-1 part 2 rooms in 1-1-1 part 2 rooms, fl, *Pour hot water into 1 part room 8a of drum B8. Connect one end of the pipe 14, the I section circulation pipe 10, and the fin pipe 12 to the lower room, the F section circulation pipe 11, the thermistor 15, and the drum pipe 13, and connect the fins to C). By connecting each end of the pipe 12 and the drum pipe 13 to the drum 7, it is possible to perform pouring and reheating at the same time. Mixing with the previous water 1) b ゛, → J--The temperature of the water in the bathtub can be accurately detected and high thermal efficiency can be obtained.

As described above, one end of the pipe, the upper circulation pipe, and the fin pipe are connected to the upper chamber of the drum B, which is separated into two upper and lower chambers by a J board. Connect the lower circulation pipe, thermistor, driver 5, and one end of the pipe to the lower chamber, and also connect the fin pipe and other parts.
By connecting the other end of the drum pipe 6 to the drum A, the thermistor detects the water temperature in the bathtub as positive (i(+').
(and) high thermal efficiency can be obtained.
