DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the present invention. The components of the present invention generally described and shown in the drawings herein can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of the present invention.

[0021] To solve the problems of low flow rate of existing boiled water system (only 450-550ml / min), long waiting time for water connection and poor consumer experience, please refer to Figure 1Schematic diagram of the working principle of the boiled water making system. The utility model proposes a boiled water making system, comprising a water tank 1, an instant heating module 2, a heat exchange module 3, a regulating valve 7, a first water pump 5, a second water pump 6 and a water outlet 4. A second temperature sensor 9 is provided on the water tank 1 for monitoring the temperature of the normal temperature water flowing out of the water tank 1, wherein the heat exchange module 3 comprises two sets of parallel heat exchange components, wherein the heat exchange component comprises a sleeved inner first water pipe and an outer second water pipe, which are formed into an elliptical shape by a coil, wherein the first water pipe and the second water pipe are both corrugated pipes, wherein the temperature resistance of the first water pipe is higher than that of the second water pipe, and the water tank 1 is connected to different heat exchange components by a first water channel S1 and a second water channel S2 respectively, so that the normal temperature water in the water tank 1 passes through the first water pipe and the second water pipe The gap between the hot water and the water flows to the instant heating module 2 for heating. The instant heating module 2 is connected to the first water pipe in the heat exchange module 3 by the third water channel S3. The third temperature sensor 10 is provided on the third water channel S3 to send the hot water to the heat exchange module 3 for heat exchange to turn it into boiled water. The heat exchange module 3 is connected to the water outlet 4 by the fourth water channel S4 to send the prepared boiled water out. The first water channel S1 is provided with a first water pump 5, and the second water pump 6 is provided on the second water channel S2. The first water pump 5 and the second water pump 6 are respectively connected to the parallel heat exchange components to supply water to the heat exchange module 3 for heat exchange, thereby forming a dual-pump dual-heat exchange design, which can improve the heat exchange efficiency and prepare more boiled water. The water volume of boiled water can be increased from the original 450-550ml / min to 1L / min.

[0022] In order to enable the boiled water production system to add a variety of water outlet types to choose from, a fifth water channel S5 is set between the instant heating module 2 and the water outlet 4 for communication, and the ends of the fourth water channel S4 and the fifth water channel S5 are merged into one channel, and a regulating valve 7 is set on the merged water channel; a sixth water channel S6 is set between the water tank 1 and the water outlet 4 for communication, and the front end of the sixth water channel S6 is set behind the second water pump 6 and connected to the second water channel S2, a first temperature sensor 8 is set on the water outlet, and the central control display screen at the top of the water outlet 4 is used to display the water temperature and control the water outlet type. Therefore, the hot water produced after heating by the instant heating module 2 and the unheated normal temperature water in the water tank 1 can be selected and controlled through the water outlet 4.

[0023] When making boiled water, the instant heating module 2 is electrically heated, and the water inlet end of the instant heating module 2 is connected to the gap between the first water pipe and the second water pipe in the heat exchange component through the third water channel S3, and the water outlet end of the instant heating module 2 is connected to the first water pipe. The normal temperature water flowing out of the water tank 1 flows into the heat exchange component through the first water channel S1 and the second water channel S2, and flows from the gap between the first water pipe and the second water pipe in the heat exchange component to the instant heating module 2 for heating. The heated hot water flows through the third water channel S3 to the first water pipe of the inner layer, and exchanges heat with the normal temperature water in the gap to become boiled water. The length of the pipe where heat exchange occurs has been fully calculated, and the prepared boiled water flows out from the water outlet 4 through the fourth water channel S4. The original boiled water system was limited by the capacity of the small water pump and the power of the instant heating module, and the boiled water flow rate was only about 500 ml per minute. This system adopts a dual-pump dual-heat exchange module design. After system debugging, it can meet the boiled water flow rate of 1L / min.

[0024] On the other hand, the first water pump 5 and the second water pump 6 can also be replaced with a third water pump with greater power to directly supply water to the parallel dual heat exchange components; or the two groups of parallel heat exchange components can be merged into one group, which is still supplied by the first water pump 5 and the second water pump 6. However, after many attempts, it was found that the above two methods are not as good as the dual-pump dual-heat exchange component form of the present invention.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved. In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
