Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to solve the technical problem that the water treatment device in the prior art can not avoid the user from drinking substandard water, as shown in fig. 1 and 2, the present application provides a water treatment method to perform water purification treatment by a purification treatment device 50, wherein the purification treatment device 50 supplies water to the outside through a direct drinking passage 30 or a hot water passage 20, and the method comprises the following steps:
acquiring water quality parameters of the purified water;
if the water quality parameter exceeds the direct drinking water threshold range, sending a signal for closing the direct drinking passage 30;
closing a channel for directly supplying water to the direct drinking passage 30 according to a signal for closing the direct drinking passage 30;
the channel for supplying water from the hot water pathway 20 to the drink-through pathway 30 is activated in response to the signal to close the drink-through pathway 30.
According to the technical scheme of the invention, the purifying container 10 can supply direct drinking water, such as normal temperature water and cold water, to the outside through the direct drinking passage 30, and supply hot water to the outside through the hot water passage 20. If through the detection of water quality testing spare 101 in the purifying container, the quality of water parameter accords with the drinking standard, then can directly drink passageway 30 and hot water passageway 20 all can normally supply water, if do not accord with the drinking standard, then can only supply water through hot water passageway 20 is outside, utilize the heating to realize disinfecting to water in order to accord with the drinking standard, and under this kind of condition, in order to satisfy the user to the drinking demand of normal atmospheric temperature water, can be with leading-in directly drink passageway 30 again of the water of hot water passageway 20, for the user provides straight drink water, convenience of customers directly drinks. Therefore, no matter whether the water quality in the water purifying container reaches the standard or not, the user can drink the drinking water meeting the standard.
Wherein, it can be understood that the water supplied by the direct drinking passage 30 can be directly drunk, the temperature is about 0-50 degrees, meanwhile, in order to protect the personal safety of the user, the temperature is not too high, and scalding is prevented. In hot weather, ice water can be drunk, so a component with a cooling function, such as a cold bladder, can be arranged in the direct drinking passage 30. When the water quality does not meet the drinking standard, the water needs to be heated through the hot water passage 20 to play a certain role in sterilization and disinfection, and because the water is purified, the water quality is unqualified at the moment, but can reach the drinking standard after being heated, and then the heated water enters the direct drinking passage 30 to cool the water to the temperature suitable for drinking and then supply the water to the outside.
In a preferred embodiment, the method further comprises the steps of:
detecting water temperature data of the direct drinking passage 30 according to a signal for closing the direct drinking passage 30;
after the water temperature data accords with the direct drinking temperature range, the terminal water supply valve of the direct drinking passage 30 is opened.
In this embodiment, the temperature of the direct drinking passage 30 can be adjusted, so that the heated water is cooled by the direct drinking passage 30 to reach a proper drinking temperature, and the drinking requirements of different users in different periods are met. Moreover, only after the temperature in the direct drinking passage 30 reaches a proper temperature, the water supply valve at the terminal of the direct drinking passage 30 is opened to supply direct drinking water to the user. The starting mode can be automatic starting or manual starting by a user after a prompt signal is sent, and the prompt signal can be a text prompt or a voice prompt.
In a preferred embodiment, the method further comprises the steps of:
sending a high-temperature operation signal of the hot water channel 20 according to a signal of closing the direct drinking channel 30;
the hot water pathway 20 heats at the upper limit heating temperature according to the high temperature operation signal, and/or the hot water pathway 20 heats at the upper limit heating time period according to the high temperature operation signal.
In this embodiment, when quality of water is unqualified, close straight drink route 30, the heating temperature of hot water route 20 is different from the heating temperature when quality of water is qualified, heats limit temperature more than 20 with the hot water route, perhaps can heat for a long time by upper limit heating, can also reach upper limit temperature after water, last heating for a long time to upper limit heating to play the disinfection effect of disinfecting, guarantee the drinking water quality standard of water.
In a preferred embodiment, if the water quality parameter exceeds the range of the direct drinking water threshold, a signal for closing the direct drinking water channel 30 is sent, and the method further comprises the following steps:
acquiring service time data of each filter element of the purification treatment equipment 50;
and if any one of the filter element service time length data exceeds the corresponding filter element service life time length, sending a signal for closing the direct drinking passage 30.
In this embodiment, in addition to detecting the water quality in the water purifying container 10, the filtering device of the purifying treatment device 50 is also detected to detect which one or more filter elements of the filtering device are in failure of reaching the filtering and purifying standard, and when the function of one or more filter elements is in failure, a signal for closing the direct drinking channel 30 should be sent. Therefore, the signal for closing the direct drinking passage 30 may be issued due to the water quality failure in the water purifying container 10 or due to the filtering and purifying function failure of the purifying treatment device 50. Corresponding detection measures are set in the water filtering stage and the water drinking stage, so that the water quality detection capability is improved, the water quality detection in the two stages also has a mutual reference function, and the detection deviation caused by the failure of the detection structure at one of the two stages is prevented, and even the prompt function is prevented from being out of order.
In a preferred embodiment, before the step of obtaining the water quality parameter of the purified water, the method further comprises the steps of:
acquiring first water quality data before a reverse osmosis filter element 53 in the purification treatment equipment 50;
