Background
At present, the main component of a water heater liner is iron, and the inner wall of the liner can generate scale when contacting with water, because tap water used by people is river water, lake water or well water, and the tap water is not pure water obtained after sedimentation, silt removal and disinfection, and the water contains various impurities and has certain corrosivity, and the liner can be slowly corroded after long-term use. In addition, water in the water heater contains a large amount of calcium and magnesium ions, and is precipitated along with the rise of the water temperature in the heating process of the water heater to form a large amount of CaCO 3 And Mg (OH) 2 The sediment forms various solid attachments, namely water scale, with different densities and different components in the inner container of the water heater.
After the scale is formed, the scale is accumulated on the surface of the inner container and is difficult to remove, so that the thermal expansion and the cold shrinkage of the inner container and uneven stress are caused, the danger of water leakage and electric leakage of the water heater due to bursting is greatly increased, the heating efficiency of the water heater is influenced, and electric energy is wasted; secondly, when the water scale is accumulated, a large amount of heavy metal ions are often attached to the water scale, so that the skin of a human body is damaged, and particularly, the skin of an infant is tender and is easy to cause red swelling and allergy of the skin of the infant.
In order to solve the problems, the cleaning of the existing water heater generally needs professional technicians to clean the water heater, but the mode is complex to operate and high in cost; the user is required to manually operate the pollution discharge cleaning device, the cleaning process is required to be monitored by the user in the whole process, the operation is complex, and time and labor are wasted; the water heater in addition is through setting up the drain, washes the inner bag repeatedly through the running water and discharges the dirt from the drain and realize automatic blowdown washing, because traditional inner bag is cylindrical, the concentration is relatively poor after the incrustation scale is piled up in the inner bag lower part, and this kind of cleaning method can only wash away a small part of floating dirt and some impurity, washs not thoroughly.
Chinese patent application No. 201310642152.7 discloses an electric water heater with scale removal and scale prevention functions, including shell, inner bag, heating pipe, control panel and ultrasonic wave generating device, wherein the inner bag is installed in the shell, and the heating pipe is arranged in the inner bag and fixed mounting in the one end of inner bag, ultrasonic wave generating device is connected with the control panel electricity, and ultrasonic wave generating device fixed mounting is at the top of inner bag and is located the top of heating pipe, and ultrasonic wave generating device's one end is inserted in the inner bag, and the other end is located the outside of inner bag to make the produced ultrasonic wave of ultrasonic wave generating device cover the heating pipe.

Alternatively, the ultrasonic cleaning device 6 may be manually turned on by the user to perform ultrasonic treatment on the scale.
The present invention provides, as one embodiment, a water heater.
When the size of the second inner container 2 is smaller, the second inner container is equivalent to a filter sleeve sleeved on the heating device 3, and the water and scale separation function is also realized; the turbidity sensor 5 and/or the flow sensor are/is arranged in the first inner container 1, and can also be arranged at the water outlet 8 of the first inner container 1.
The invention also provides a scale cleaning method applied to the water heater.
The scale cleaning method of the water heater comprises the following steps:
s1: starting an ultrasonic cleaning device after receiving a starting signal;
s2: the incrustation scale after being shaken garrulous by ultrasonic cleaning device discharges to first inner bag in from second inner bag bottom, discharges through the first drain hole of first inner bag bottom, accomplishes the clearance of incrustation scale.
Step S1 includes an activation signal generated when the user manually turns on or an automatic activation signal sent by the detection device.
The automatic starting signal sent by the detection device can be a starting signal sent by detecting that the turbidity of the water reaches a preset turbidity value; the starting signal can be sent out when the flow of the detected water reaches a preset flow value; the starting signal can be sent out when the heating time reaches the preset time; or a combination of two or three of them.
Specifically, the water heater incrustation scale cleaning method that this scheme provided does: water passes through the water inlet and gets into in the first inner bag, filter the hole through the second inner bag and directly get into in the second inner bag, utilize heating device to heat water, the good water of heating discharges in the first inner bag from the filtration hole of second inner bag, with the interception of large granule incrustation scale in the second inner bag, play effectual water, the effect of scale separation, and the drainage speed that the hole was filtered to the top is greater than the drainage speed that the hole was filtered to the below, it is intraductal that the water of arranging in the first inner bag flows into the hot water by the delivery port, in order to use.
After the ultrasonic cleaning device is used for a period of time, a user starts the ultrasonic cleaning device; or when the turbidity sensor detects that the turbidity of the water reaches a preset turbidity value, and/or the flow sensor detects that the flow of the water reaches a preset flow value, and/or the time detection device detects that the heating time of the water reaches a preset time, the ultrasonic cleaning device is started, and the ultrasonic waves can cover the whole area in the first inner container, particularly the position of the filtering part.
Most of the scale after being shattered by the ultrasonic cleaning device is discharged into the first liner from a second sewage discharge outlet at the bottom of the second liner, and a small part of the scale is discharged from a filtering hole below the second liner; and finally, discharging the water scale through a first discharge port at the bottom of the first inner container to finish self-cleaning and periodic cleaning of the water scale.
The reason why the water inlet speed of the first inner container and the water outlet speed of the second inner container are kept higher than the water outlet speed is to keep the first inner container and the second inner container filled with water all the time and to give enough heating time to the water.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
