Description
Technical Field
The utility model belongs to the technical field of water treatment, more specifically say, relate to a water treatment facilities of adjustable leaving water temperature.
Background
The existing water treatment equipment usually has a hot water function, and can output water with different temperatures according to the requirements of users. How to provide hot water with different temperatures in time to meet the requirements of different users is a problem to be solved urgently.
The existing products usually adopt two heating technologies in order to realize different temperature requirements, one is to heat hot water by using an instant heating module, and the instant heating is realized by opening. The instant heating has the advantage that water with different temperatures can be obtained in time through the heating module and the temperature control module. For example, patent document 1 provides a safe and energy-saving instant heating type drinking water device, which exchanges heat with hot water and outputs hot water quickly through a heat exchange box fixedly arranged in a machine body, a quick heating liner fixedly arranged in the machine body and a control system arranged on the machine body. Patent document 2 provides a rapid heating control method and device, and an instant heating device, in which a specific rapid heating control model is adopted to adjust the heating power of an electric heating element through the electric heating element connected with a Silicon Controlled Rectifier (SCR) and a power supply, so as to realize rapid heating and accurate temperature control. However, the instant heating module has high power, and when the instant heating module is used in a household, the power is limited by the power load, and usually only about 2kw of power is available, so that the instant heating flow is small under the power, and the hot water with large flow cannot be obtained, thereby affecting the user experience.
Another heating method in the prior art is to heat water through a heat storage tank, i.e., a tank of water is heated well in advance. For example, patent document 3 discloses an instant hot water pipe for a water heater, in which a water storage pipe and a water discharge hole are provided, so that when a water outlet end of the water heater is closed, the water storage pipe rotates to the lower side of a pipe body, stored water in the pipe body is directly discharged into the water storage pipe for temporary storage, and when the water heater is used next time, hot water is directly discharged, thereby reducing waiting time. At present, a mode of heating hot water by utilizing a heat storage tank is generally to heat water and preserve heat at a certain temperature, and the hot water storage tank has the advantages that hot water with a larger flow can be obtained, and the disadvantage that hot drinking water with different temperature requirements is difficult to obtain due to the fact that the hot water is preserved at a certain temperature.

Example 6
The basic content of this embodiment is different from that of embodiment 1 or 3 in that: as shown in fig. 6, in the present embodiment, a water outlet is provided on the normal-temperature water delivery pipeline between the normal-temperature water unit and the mixed water outlet; one end of the return pipeline is connected with the water outlet port, and the other end of the return pipeline is connected with the normal-temperature water unit. When the normal temperature water unit of this embodiment is the water purification filter core, this water purification filter core is composite filter core, and it has filter core, filtration membrane and aftertreatment filter core in advance. Normal temperature water flow control valve connects between filtration membrane and muddy water export, and return line one end is connected with the branch mouth of a river, and the other end is connected with the input of normal temperature water pump. The filtering membrane can be a reverse osmosis membrane or a nanofiltration membrane. It should be noted that one end of the return line is connected to the front of the normal temperature water pump, and the other end of the return line can be connected between the filtering membrane and the post-treatment filter element, or can be connected between the post-treatment filter element and the normal temperature water flow regulating valve.
It should be noted that although in embodiment 1, the actual flow rate of the normal temperature water finally obtained is 0.25L/min, the actual flow rate of the normal temperature water output by the water treatment unit is higher than the flow rate of the normal temperature water corresponding to the actual flow rate of the normal temperature water. In order to realize the purpose of accurate temperature control, in the embodiment, redundant normal-temperature water output from the water treatment unit flows back to the water treatment unit, and the normal-temperature water with the corresponding flow is output only according to the obtained actual flow rate of the normal-temperature water. The corresponding rotating speed matched with the hot water pump is adjusted and generated by combining the hot water pump, so that the set flow speed of the hot water with the corresponding flow output from the heating unit is controlled, and the requirements of users on the outlet water temperatures with different temperatures are met in time.
In some embodiments, it is understood that the outlet water temperature can be adjusted by adjusting the actual flow rate of the normal temperature water and the actual flow rate of the hot water at the same time.
More specifically, although exemplary embodiments of the invention have been described herein, the invention is not limited to these embodiments, but includes any and all embodiments modified, omitted, such as combinations between various embodiments, adapted changes and/or substitutions as would be recognized by those skilled in the art from the foregoing detailed description. The limitations in the claims are to be interpreted broadly based the language employed in the claims and not limited to examples described in the foregoing detailed description or during the prosecution of the application, which examples are to be construed as non-exclusive. Any steps recited in any method or process claims may be executed in any order and are not limited to the order presented in the claims. The scope of the invention should, therefore, be determined only by the appended claims and their legal equivalents, rather than by the descriptions and examples given above.
