Description
Technical Field
The invention belongs to the technical field of washing machines, and particularly relates to a method for judging a faucet switch in a drying process of a washing machine.
Background
The drum washing machine is a common household appliance, can provide great convenience for the life of people, and becomes one of the indispensable household appliances in daily life of people. A drum washing machine generally includes an outer tub and an inner tub rotatably mounted within the outer tub. When the clothes are washed, the clothes are driven by the inner drum to move, so that the washing effect is achieved.
For the drum washing machine with the condensing type drying function, in the drying process, condensed water needs to be continuously introduced, the drying efficiency is improved through the condensation effect of the condensed water on the humid air in the drum, the normal drying is ensured, if the water faucet is closed in the drying process, no condensed water flows in, the drying efficiency is greatly reduced, the condition that clothes cannot be dried easily occurs, and therefore, the water faucet is opened in the drying process to be very important. The traditional mode of judging the tap switch is mostly to utilize the difference of water level frequency before and after intaking, but the condensate water among the drying process can directly discharge after flowing in, and water level frequency changes less, is difficult to judge to there is the difference also in initial water level frequency between different washing machines, produces the condition of erroneous judgement more easily.
Disclosure of Invention
The invention aims to provide a method for judging the opening and closing of a water faucet in the drying process of a washing machine.
In order to solve the technical problems, the invention is realized by the following technical scheme:
the invention relates to a method for judging a faucet switch in the drying process of a washing machine, which comprises the following steps;
the method comprises the following steps: collecting T1, T2 and T3, wherein T1 is the temperature of the water heating pipe T time before the condensed water enters; t2 is the temperature of the water heating pipe when the condensed water enters; t3 is the temperature of the water heating pipe T time after the condensed water enters;
step two: and (3) starting drying, calculating the slope K1 of the temperature curve of the water heating pipe within t time before the condensed water enters, and then calculating the slope K2 of the temperature curve of the water heating pipe within t time after the condensed water enters, wherein K1 and K2 are represented by the following formula:
K1＝(T2-T1)/t；
K2＝(T3-T2)/t；
step three: comparing the slopes of the two temperature curves K1 and K2, and calculating the change rate P of the slope of the temperature curve of the water heating pipe, wherein the change rate P is represented by the following formula;
P＝(K1-K2)/K1；
if P is more than or equal to 0.3, judging that the faucet is opened; if P is less than 0.3, the water tap is judged to be closed.
Further, the t time was 5 min.
The invention has the following beneficial effects:
when the drying program of the drum washing machine is operated to the step of entering the condensed water, the temperature rising speed is rapidly reduced and even the temperature is reduced because the condensed water flows into the water heating pipe, compared with the condition before entering the condensed water, the slope of the temperature curve is greatly changed, so the change of the slope of the temperature curve of the water heating pipe in a period of time before and after entering the condensed water is compared, and the purpose of judging the opening and closing of the faucet is achieved.
Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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 invention.
Referring to fig. 1, the present invention is a method for determining a faucet switch during a drying process of a washing machine; the principle of the method for judging the water tap switch in the drying process of the washing machine is as follows:
in the drying process of the drum washing machine, after hot air enters the inner barrel, the hot air exchanges heat with air in the inner barrel to form wet air, the wet air is brought out of the inner barrel along with circulating air in the barrel, and when the wet air passes through the condensation disc, moisture in the wet air is condensed and flows to the water heating pipe at the bottom of the barrel.
Before the condensing valve is opened, no condensed water exists in the condensing disc, the temperature of the moisture flowing from the humid air to the water heating pipe is very high, and at the moment, the temperature rising speed at the water heating pipe is very high; after the condensing valve is opened, the condensing disc is filled with condensed water with lower temperature, the temperature of the water flowing to the water heating pipe is rapidly reduced, and the temperature change rate of the water heating pipe can be obviously changed. Before condensed water enters, calculating the slope of a temperature curve of the water heating pipe within a certain time, after the condensed water enters, calculating the slope of the temperature curve of the water heating pipe at the same time, comparing the slopes of the two temperature curves before and after the condensed water enters, and when the difference value of the slopes of the two is greater than a certain value, judging that the condensation valve is opened at the moment, wherein the solid line part in figure 1 shows that the condensed water flows into the condensation tray, otherwise, judging that the condensation valve is closed at the moment, and the dotted line part in figure 1 shows that the condensation valve is closed. According to the method, whether the condensed water flows in can be judged, and then the switch of the faucet can be judged.
Referring to fig. 2, the method for judging the opening and closing of the faucet in the drying process of the washing machine includes the following steps;
the method comprises the following steps: collecting T1, T2 and T3, wherein T1 is the temperature of the water heating pipe T time before the condensed water enters; t2 is the temperature of the water heating pipe when the condensed water enters; t3 is the temperature of the water heating pipe T time after the condensed water enters;
step two: and (3) starting drying, calculating the slope K1 of the temperature curve of the water heating pipe within t time before the condensed water enters, and then calculating the slope K2 of the temperature curve of the water heating pipe within t time after the condensed water enters, wherein K1 and K2 are represented by the following formula:
K1＝(T2-T1)/t；
K2＝(T3-T2)/t；
step three: comparing the slopes of the two temperature curves K1 and K2, and calculating the change rate P of the slope of the temperature curve of the water heating pipe, wherein the change rate P is represented by the following formula;
P＝(K1-K2)/K1；
if P is more than or equal to 0.3, judging that the faucet is opened; if P is less than 0.3, the water tap is judged to be closed.
