Description
- The present invention relates to a heating device, and more particularly to a water heater for heating water.
- A conventional water heater, as shown in
FIG. 3 , has atank 2 for storing water, acold water pipe 21, ahot water pipe 22, and aheating device 23. Cold water flows from thecold water pipe 21 to thetank 2. The cold water is heated by theheating device 23 to form hot water. The hot water is stored in thetank 2. The hot water is output from thehot water pipe 22 when it is used. - However, in the above conventional structure, when a certain amount of hot water is taken, cold water is replenished into the
tank 2 through thecold water pipe 21 and then mixed with the hot water in thetank 2, resulting in a decrease in temperature. On the other hand, since theheating device 23 heats all the water in thetank 2, it takes more time to heat the water to a desired temperature due to too much water. In this way, as long as cold water enters thetank 2, the temperature of the water in thetank 2 will be affected and cannot be maintained within a certain range. It is necessary to wait for a period of time for the water to reach the predetermined temperature. During this time, if the hot water is continuously output and the cold water is replenished, it is hard to rise the temperature of the water in thetank 2. - Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
- The primary object of the present invention is to provide a water heater, which increases the water temperature by means of a circulating heating method, maintains the constant temperature of hot water, and outputs hot water stably.
- In order to achieve the above object, the water heater of the present invention comprises a tank and a heating pipe. The tank has a water storage space therein. A bottom of the tank is provided with a cold water inlet and a circulation outlet. The tank is provided with a hot water outlet located a position not less than one half height of the tank. The heating pipe extends upward from the bottom of the tank to the water storage space. The heating pipe is provided with an opening facing sideways. The opening is located at a certain height of the water storage space. The heating pipe is connected with a circulation pipe outside the tank to communicate with the circulation outlet. An outside of the heating pipe is provided with a heating device for heating the heating pipe.
- In an embodiment, the heating pipe extends upward in the water storage space to a position not less than one half height of the water storage space. The opening is located at the position not less than one half height of the water storage space.
- In an embodiment, one end of the heating pipe is bent sideways to form a bent section. The opening is located at a distal end of the bent section.
- In an embodiment, the cold water inlet is provided with a cold water control valve. The hot water outlet is provided with a hot water control valve. A water level sensing unit is provided in the water storage space and electrically connected to the cold water control valve.

FIG. 1 is a sectional view of the present invention; -
FIG. 2 is a schematic view of the present invention when in use; and -
FIG. 3 is a sectional view of a conventional water heater. - Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
- As shown in
FIG. 1 , a water heater in accordance with the present invention comprises atank 1 having awater storage space 11 therein. The bottom of thetank 1 is provided with acold water inlet 12 connected with acold water pipe 121 so that external water can flow into thewater storage space 11. The bottom of thetank 1 is provided with acirculation outlet 13 connected with acirculation pipe 131 so that the water in thewater storage space 11 can be output through thecirculation outlet 13. Thetank 1 is provided with ahot water outlet 14 located at a first position not less than one half height of thetank 1. Thehot water outlet 14 is connected with anoutput pipe 141 so that the water in thewater storage space 11 can be output through thehot water outlet 14. - In this embodiment, the
cold water inlet 12 is provided with a coldwater control valve 122 for controlling the flow of water passing through thecold water inlet 12. Thehot water outlet 14 is provided with a hotwater control valve 142 for controlling the flow of water passing through thehot water outlet 14. In addition, a waterlevel sensing unit 15 is provided in thewater storage space 11 and is electrically connected to the coldwater control valve 122. When the waterlevel sensing unit 15 detects that the water level in thewater storage space 11 is insufficient, the coldwater control valve 122 is actuated to inject external water into thetank 1. - The bottom of the
tank 1 is provided with aheating pipe 16. Theheating pipe 16 is connected with thecirculation pipe 131 outside thetank 1, so that theheating pipe 16 communicates with thecirculation outlet 13. Theheating pipe 16 extends upward in thewater storage space 11. The distal end of theheating pipe 16 is provided with an opening 162 facing sideways. In this embodiment, theheating pipe 16 extends upward to a second position not less than one half height of thewater storage space 11. The top end of theheating pipe 16 is bent sideways to form abent section 161. The opening 162 is disposed at the distal end of thebent section 161. The outside of theheating pipe 16 is wrapped with aheating device 163. Theheating device 163 is configured to heat theheating pipe 16. - With the above structure, when in use, as shown in
FIG. 2 , the water in thewater storage space 11 is output from thecirculation outlet 13 to enter theheating pipe 16 through thecirculation pipe 131. The water is heated by theheating device 163 to rise the temperature, and then the hot water is output from theopening 162 to enter thewater storage space 11 again. At this time, since the opening 162 faces sideways, the hot water is sprayed out sideways in a swirling flow state after hitting the inner wall of thetank 1 to flow upward and downward respectively. The water that flows upward helps the water molecules rub and collide with each other and maintain its temperature. The water that flows downward is mixed with the cooler water. Since theopening 162 is located at a third position not less than one half height of thewater storage space 11, thewater storage space 11 is divided into acold water area 111 in the lower half and ahot water area 112 in the upper half. There is no physical boundary between thecold water area 111 and thehot water area 112. Based on the difference in the density of the cold water and the hot water, the cold water will sink and the hot water will rise, and therefore there is a convection phenomenon in thewater storage space 11. - When the hot water is to be taken, the hot water can be obtained through the
hot water outlet 14. Since thehot water outlet 14 is disposed at the first position not less than one half height of thetank 1, that is, in thehot water area 112 of thewater storage space 11, it can be ensured that the obtained water is hot water. - On the other hand, when the water level in the
water storage space 11 is insufficient, the external water, which is cold, is injected into thewater storage space 11 through thecold water inlet 12. Since thecold water inlet 12 is located at the bottom of thetank 1, the cold water enters thecold water area 111 of thewater storage space 11. Thecirculation outlet 13 is also located in thecold water area 111, so the cold water continuously sinks in thecold water area 111 and is discharged from thecirculation outlet 13 nearby without rising into thehot water area 112. Accordingly, the present invention does not affect the temperature of the outputted hot water when replenishing the external water source. - In addition, the
heating device 163 heats only the water in theheating pipe 16, and the temperature of the water in the pipe can be rapidly increased to a desired temperature due to the small amount of water in the pipe. - Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
