Cold water charging and heating device in hot water pipe of water heater

The present invention relates to a cold water charging and heating device in a hot water pipe of a water heater, in particular to a water purifier installed at the end of a hot water pipe of a water heater, except that the unheated cold water in the hot water pipe can be taken through the cold water pipe through the water heater After heating, it can be saved by the user, which can save considerable water resources. If it is about 10 liters of cold water that is wasted by waiting for hot water before bathing every day, and then calculated by 20 million people, the water is wasted every day. Up to 200 million liters, the waste of such high-quality water resources over the years, can be described as a major disrespect for nature, it is really violent.

According to the traditional water heater (or solar water heater), when there is cold water in the hot water pipe, when the hot water faucet is turned on, it will always wait for a period of time before the cold water flows out, so that hot water will flow out. Every day, about 10 to 30 liters of water is lost per person, which not only drains personal time, drains money, but also drains valuable earth water.

The reason is that the main purpose of this creation is to provide a cold water charging and heating device for the hot water pipe of the water heater, which is mainly installed at the end of the hot water pipe of the water heater, which can be burned by the water heater before use. The cold water in the hot water pipe is returned to the water heater through the cold water pipe of the water heater, so that the water heater supplies hot water within the set time of the user.

In order to achieve the above objectives, the author adopts the following technical means: a cold water charging and heating device in a hot water pipe of a water heater, the water heater has a cold water pipe at one end and a hot water pipe at the other end, and several cold and hot water pipes are respectively connected to each other. Hot water tap; characterized in that: a water purifier is installed at the extreme end of the hot water pipe, and the other end of the water purifier is connected to the end of the cold water pipe; the water heater is internally provided with a temperature controller, a time controller and a counter Stop valve, where temperature control The temperature of the hot water is controlled by the time controller; the time controller calculates the time required for the hot water to flow to the hot water tap at the end of the hot water pipe after the water heater is started; the check valve controls the return of the unheated cold water in the hot water pipe to the cold water. The hot water that has been heated in the tube or in the hot water pipe is no longer returned to the cold water pipe.

The second figure is a schematic diagram of the water supply pipe of the cold water collecting and heating device in the hot water pipe of the second embodiment of the present water heater.

Referring to the first figure, a schematic diagram of a water supply pipe for a cold water collecting and heating device in a hot water pipe of the first embodiment of the present invention, wherein the water heater 10 has a cold water pipe 11 at one end and a hot water pipe 12 at the other end, a hot water pipe A plurality of hot water taps 121 are connected to the pipeline of 12, and a plurality of cold water taps 111 are connected to the pipeline of the cold water pipe 11; wherein: the water heater 20 is installed at the end of the hot water pipe 12, and the other end of the water purifier 20 is installed. The system is connected to the end of the cold water pipe 11, and the water heater 20 is internally provided with a temperature controller 21, a time controller 22, and a check valve 23, wherein the temperature controller 21 controls the temperature of the hot water (such as 38). °C), the time controller 22 calculates the total time required for the hot water to flow to the hot water tap 121 at the end of the hot water pipe 12 after the water flow is started from the water heater 10, for example, after the water flow is started from the water heater 10, the hot water flows to the hot water pipe 12 The total time required for the hot water faucet 121 is 1 minute. At the same time as the start of the preheating start time, the check valve 23 opens its one-way flow path, and the cold water in the hot water pipe 12 is heated without being burned. The flow to the cold water pipe 11 is heated, so that the user does not want the hot water to waste the water stored in the original hot water pipe 12, and when the warm-up time is terminated for one minute, the check valve 23 automatically closes the single. To the flow path, the hot water in the hot water pipe 12 is already warm, and the cold water in the cold water 11 is no longer returned to the hot water pipe 12 during use, and is directly taken by the user to open the tap.

Referring to the second figure, a schematic diagram of the water supply pipe of the cold water collecting and heating device in the hot water pipe of the second embodiment of the present invention is described. In the water heater 10, a water slinger 20' is installed under the water heater 10, and the water hopper 20' is internally The device is provided with a temperature controller 21, a time controller 22, and a check valve 23, wherein the temperature controller 21 controls the temperature of the hot water (for example, 38 ° C), and the time controller 22 calculates the water flow from the water heater 10 after starting. The hot water flows to the hot water tap 121 at the extreme end of the hot water pipe 12 for a total time. For example, after the water flow is started from the water heater 10, the hot water flows to the hot water tap 121 of the hot water pipe 12 for a total time of 1 minute. At the same time as the start of the preheating start time, the check valve 23 opens its one-way flow path, and the cold water that has not been heated by the combustion in the hot water pipe 12 is returned to the cold water pipe 11 for heating, so that the user does not want to obtain The water stored in the original hot water pipe 12 is wasted by the hot water. When the warm-up time is terminated for one minute, the check valve 23 also automatically closes its one-way flow path, so that the hot water pipe 12 has already heated the hot water. ,use 11 is no longer cold water is returned to the cold water pipe 12, and taken directly for the user to open the tap.

In summary, the cold water collecting and heating device in the hot water pipe of the water heater is installed at the end of the hot water pipe of the water heater, and the water purifier can make the water heater not need to wait when the hot water tap is turned on. You can have hot water flowing out to save water. The practical effect is undoubted, and this creation has never been made public or has been seen in other publications. It has already complied with the provisions of the Patent Law and has filed a patent application according to law.
