The following describes the water producing apparatus according to an embodiment of the present invention with reference to fig. 1, and the water producing apparatus according to an embodiment of the present invention may be a household water purifier, such as a kitchen-type water producing apparatus, or may be a table-type water producing apparatus.
As shown in fig. 1, the water producing apparatus comprises: a filtration system 110, a heating system 120, a regulator valve 131, an input module (not shown), and a controller (not shown).
Wherein, the filtering system 110 is used for filtering impurities in the raw water and outputting purified water.
As shown in fig. 1, the filtering system 110 has a water inlet 111 and a water outlet 112, the water inlet 111 of the filtering system 110 is connected to the raw water inlet 101 of the water producing device, and the raw water inlet 101 of the water producing device may be directly or indirectly connected to a raw water source, for example, the raw water source may be tap water or well water.
The outlet 112 of the filter system 110 outputs filtered purified water.
The filtration system 110 may also have a waste water port 113, and the waste water port 113 of the filtration system 110 is connected to the drain port 102 of the water producing apparatus.
The heating system 120 has a water inlet 121 and a water outlet 122, the water inlet 121 of the heating system 120 is connected to the water outlet 112 of the filtering system 110, and the heating system 120 is used for heating purified water output from the filtering system 110 to provide hot water.
In practical implementation, the heating system 120 may perform heating according to a set stop temperature, the set stop temperature may be 72 ℃ to 110 ℃, and the specific value of the stop temperature may be determined according to the altitude of the region, or the boiling point of water in the region.
The water outlet 112 of the filtering system 110 is connected with the first water supply port 103 of the water making device; the water outlet 122 of the heating system 120 is connected to the second water supply port 104.
The first water supply port 103 is used to supply normal temperature purified water filtered by the filtering system 110. The second water supply inlet 104 is used to supply hot purified water filtered by the filtering system 110 and heated by the heating system 120.
A first end of the regulating valve 131 is connected to the water outlet 112 of the filtering system 110, and a second end of the regulating valve 131 is connected to the water outlet 122 of the heating system 120.
When the temperature-adjusted water needs to be provided, the normal temperature purified water flowing out of the water outlet 112 of the filtering system 110 passes through the adjusting valve 131, is mixed with the hot water flowing out of the water outlet 122 of the heating system 120, and flows out of the second water supply port 104. In other words, the second water supply port 104 is also used to supply tempered water.
The temperature of the temperature-adjusted water depends on the mixing ratio of the normal-temperature water and the hot water, that is, the opening degree of the adjusting valve 131.
The purified water obtained by filtration of the filtration system 110 is divided into two branches: the first branch is that a part of purified water flows into the second water supply port 104 through the regulating valve 131; the second branch is that another portion of purified water flows into the heating system 120, and the heating system 120 outputs hot water and flows into the second water supply port 104.
That is, the purified water obtained by the filtering system 110 finally flows out of the second water supply port 104 by mixing.
It can be understood that, in the related art, when the temperature-regulated water needs to be taken, the technical means adopted is to adjust the flow rate of the normal-temperature water, in other words, the filtering system cannot always maintain the maximum water production.
The input module is used for receiving input information, the controller is in communication connection with the regulating valve 131 and the input module, and the controller is configured to control the opening of the regulating valve 131 based on the input of the input module.
According to the water making equipment provided by the embodiment of the invention, when hot water, normal-temperature water or temperature-adjusted water is taken, the maximum water outlet flow is the same, particularly when the temperature-adjusted water is taken, the filtering system 110 can filter the water with the maximum flow, and the water temperature can be adjusted by distributing the proportion of the filtered pure water in the two branches.
According to the water making equipment provided by the embodiment of the invention, the temperature regulating valve is arranged between the normal-temperature water branch and the hot water branch, so that the temperature regulating water can be output at a large flow rate, and the actual requirements of users are met.
The communication connection in the embodiments of the present invention may be a wired electrical connection through a cable, or a wireless electrical connection through a wireless transceiver.
The input module may include, but is not limited to, the following structural forms:
first, the input module may include a touch display or a touch panel.
Thus, the user can realize input through touch operation on the input module, wherein the touch operation comprises clicking, pressing, sliding and the like; this input can be used to switch on and off the water production plant, or to select a water use mode, or to select a target temperature.
Second, the input module may include a microphone.
Thus, the user can control the water making device by voice, including controlling the on/off of the water making device, or selecting the water using mode, or selecting the target temperature, such as receiving voice "water temperature 60 degrees", and through voice collection and semantic recognition, the controller outputs a corresponding control instruction to control the opening degree of the regulating valve 131, and outputs the temperature-regulated water of about 60 ℃ from the second water supply port 104.
Thirdly, the input module may include physical keys.
Therefore, the user can realize the switch of the water making equipment, or select the water using mode, or select the target temperature by pressing the input module.
According to the water making equipment provided by the embodiment of the invention, the temperature regulating valve is arranged between the normal-temperature water branch and the hot water branch, and the opening degree of the temperature regulating valve is controlled by the input module and the controller, so that the temperature regulating water can be output at a large flow rate, and the actual requirements of users are met.
