Description

Heater

The invention relates to a heater.

As shown in FIG. 1 , the conventional heater mainly comprises a cylinder body, a heating pipe 11, a water inlet pipe 12 and an outlet pipe 13 . The cylinder body has a partition 14 inside. The partition plate 14 has an inner top plate 15 above the inlet pipe 12 . Passing through the inner top plate 15, the water inlet pipe 12 introduces water into the outer periphery of the partition plate 14, and the inner top plate 15 has a flow port 16.

In addition, as shown in FIG. 2, another conventional heater mainly comprises a cylinder 20, a heating pipe 21, an inlet pipe 22 and an outlet pipe 23. The cylinder 20 has a partition 24 therein, which is a heating zone 240 and a heating zone. 240 is introduced into the heating pipe 21, and the outlet pipe 23 is led out of the casing 20 above the heating zone 240. The inlet pipe 22 is introduced from the casing 20 into the heating zone 240, and the partition 24 has a flow port 25.

However, the separators of the above conventional heaters are all made of a single metal plate. After the water in the separator is heated, the water is still transmitted through the separator to the water outside the separator, and the unheated water outside the separator is also Cooling the partition plate makes the heating tube not perform well and consumes energy.

In addition, Figure 9 of TW M338338 discloses a hot and cold compartment bucket, wherein the compartments at the compartments of the two compartments are provided with venting holes for the mutual communication between the adjacent compartments, and the guiding tube extends from the upper end of the compartment. Approaching the bottom of the hot and cold compartment barrel, thereby directing the higher temperature liquid from the previous compartment to the lower temperature zone of the lower part of the next compartment, however this will result in a relatively higher temperature of the previous compartment. The hot liquid is mixed in a large amount with the relatively low temperature cold liquid phase in the next compartment, and the hot liquid immediately after heating cannot be used immediately, and the heat utilization rate is poor and energy is consumed. In addition, the transverse partition of the hot and cold compartment barrel is provided with an upwardly venting opening above the last compartment, thereby maintaining a pressure equalization between the compartments, wherein the compartment is connected to the upper end The vent must be above the inlet of the draft tube to ensure that the effluent does not flood the vent on the upper end of the compartment and the vent that is traversed in the upper direction of the last compartment. Although TW M338338 discloses the top surface of the diaphragm and is provided with a heat insulating material, in order to avoid heat exchange between the gas on the top surface of the diaphragm and each space, the structure cannot be immediately blocked. Heat exchange between the hottest hot liquid and the cooler liquid around the heater, and the heated hot liquid needs to pass through the draft tube extending from the upper end of the compartment to the bottom of the hot and cold compartment barrel, except The flow path is extremely long and the heat energy is easily lost. The higher temperature liquid will flow further to the lower part than the lower temperature liquid, and then flow to the liquid outlet. It is impossible to solve the mixed heat and cold liquid and the thermal efficiency is poor. It is not possible to directly use the hottest liquid around the heater.

Therefore, it is necessary to provide a novel and progressive heater to solve the above problems.

The opening of the C-shaped elongated member is opposite to the extending direction of the heat flow conduit 34 and is set to be cold. The flow channel 35a, the C-shaped elongated member encloses the heating zone 32a, and the heating zone 32a is defined as a three-dimensional heating space surrounded by the heat insulating portion, and the heat insulating portion has a sectional area smaller than that of the inner portion of the cylinder Cross-sectional area. In addition, the heat insulating portion 31a extends in a direction opposite to the extending direction of the heat flow conduit 34 to surround the three-dimensional heating space that is open on one side, and the heating device 40 extends into the three-dimensional heating space. The C-shaped long piece can be, for example, a single piece a hollow piece obtained by folding and joining, a hollow piece connected by a plurality of sheets, or a single solid piece body. If the C-shaped long piece is hollow, the material may be metal or non-metal, if the C-shaped long piece is Solid, the material is preferably a heat insulating material as described above. The C-shaped elongated member includes a C-shaped cross-section having a curvature greater than 80 degrees, preferably between 140 and 180 degrees, to ensure that the heated water does not overflow and is completely directed through the heat flow conduit 34 to the non-heating zone 33a. For the water supply. Preferably, the water inlet 36 is located below the outer side of the heat insulating portion 31a and near the bottom of the cylindrical body 30, so as to prevent low water from directly mixing into the heating zone 32a, thereby improving instantaneous heat and heating efficiency.

In still another embodiment as shown in Figs. 10 and 11, it differs from the heater of the embodiment shown in Figs. 7 to 9 in that the heat insulating portion 31b of the heater has a long and horizontal shape. Provided in the cylinder 30, the opening of the dome-shaped long member is opposite to the extending direction of the heat flow conduit 34 and is set as the cold flow passage, and the dome-shaped elongated member encloses a heating zone 32b. The castellal elongate member has a free end 314 that is not coupled to the barrel 30, the free end 314 being provided with a longitudinal end wall 315. In the direction in which one of the heating device 40 and the longitudinal end wall 315 extends, the distance from the longitudinal end wall 315 to the heat flow conduit 34 is less than the distance from the inner wall of the cylinder 30, thereby enhancing the heating and instant heat effects.
