Abstract
The utility model discloses an anode bar consumption detection prompter and a water heater using the device. An anode bar of the prompter is arranged in a liner of the water heater, and is directly connected with the liner in a non-insulating manner, so that an insulating connection device between the anode bar and the liner can be omitted, the assembling can be facilitated, and the continuous current protection of the anode bar to the liner can be guaranteed; a current detection module is arranged between the anode bar and an electric heater, and a current-limiting resistor is connected in series in a circuit, so that the electric heater can be protected correspondingly, and the anode bar is not over consumed; a processing module is used for prompting through a warning prompt module according to the comparison of the value of protective current detected by the current detection module and the standard protective current value, so that early or late improper replacement caused by that the actual protective current is higher or lower than the standard protective current value can be avoided.
Description
Technical field
The utility model relates to the water-heater that a kind of anode bar consumption detects suggestion device and uses this device.
Background technology
Current water heater liner major part on the market is metal material, for preventing the inner bag corrosion, common processing mode is to adopt enamel inner container, but due to problems such as production technique, working conditions, enamel there will be indivedual flaws, especially the interface of inner bag and welding of longitudinal seam and circumferential seam part very easily produce corrosion, cause inner bag to leak.
For more comprehensively protection, anode bar is installed usually on water heater liner, adopt the scheme of sacrificial anode further to protect inner bag.In the process that anode bar is used at water-heater, continue to consume, because the performance of water-heater own, user's use-pattern, frequency of utilization, local water quality, quality of anode, the inner bag quality, enamel quality etc. are variant, so some anode bars can be even longer with 5 years, and poor work-ing life is even lower than 1 year, if now the user changes anode bar not in time, water heater liner will lose protection, time one is long, thereby will cause the inner bag corrosion to leak, the lighter's water-heater is scrapped, severe one causes immersion, even cause the serious accidents such as electric shock, bring serious personal injury to the user.
Anode bar generally all is arranged at inner bag inside, and the user wants to know the Expenditure Levels of current anode bar, anode bar can only be pulled down; but the dismounting of anode bar bothers very much, to have torn open early and be not finished, replacing can cause waste; tearing inner bag open late has just started corrosion, does not have the effect of sustainable protection.
Settling mode commonly used is that the anode rod replacement alarm set is installed on water-heater at present, and anode bar and inner container insulating are installed, by detecting the protective current between anode bar and inner bag and contrasting and judge whether to need to change anode bar with standard protective current value.Standard protective current value arranges a fixed value by producer mostly; but because the aspects such as the performance of water-heater own, user's use-pattern, frequency of utilization, local water quality, quality of anode, anode electric weight, inner bag quality, enamel quality there are differences; there will be the real protection electric current higher or lower than standard protective current value; will too early or spend evening like this and remind, cause replacing improper opportunity.
Chinese patent literature CN102853551A discloses a kind of water-heater anode bar and has consumed reminding method and device, and described method comprises the steps: that described current detecting unit detects the protective current Imax between described anode bar and inner bag and passes to described processing unit; Described processing unit calculates alarm current Imin=K * Imax, wherein, and K=0.05～0.5; Described current detecting unit detects the real-time current I between described anode bar and inner bag and passes to described processing unit; Described processing unit records time length or the number of times that described real-time current I is less than alarm current Imin, when described time length or number of times are more than or equal to set(ting)value, sends hint instructions to described Tip element; Described Tip element consumes prompting according to the hint instructions of described processing unit.The problem that this invention exists is; at first; what current detecting unit detected is the protective current between anode bar and inner bag; therefore requiring anode bar and inner bag is insulating mounting; increased the installation difficulty of anode bar; introduce additional resistance in current loop, weakened the intensity to the inner bag protective current, if anode bar meeting less than normal causes anode inadequate to the protection of inner bag simultaneously.

A kind of anode bar consumption detects suggestion device, comprise be installed in water heater liner and with the nonisulated direct-connected anode bar of described inner bag, be installed on the electric heating tube of installing with described inner container insulating in inner bag, detect the current detection module of protective current between described anode bar and electric heating tube outer wall, described current detection module is electrically connected to processing module and alarm module successively; The protective current that described processing module records according to current detection module and standard protective current value relatively, are reminded by the alarm module during lower than normal value.
Especially, be serially connected with a current-limiting resistance between described anode bar and electric heating tube outer wall.
Further, described anode bar is installed on described inner bag by screw thread, and both directly connect and conducting by screw thread.
Further, described anode bar is installed on flange, and is installed on described inner bag by flange is fastening, and anode bar is successively through flange, holding bolt and inner bag conducting.
Preferably, described current detection module adopts the mutual inductor testing circuit to obtain the protective current value.
Preferably, described current detection module is obtained the protective current value by measuring the current-limiting resistance both end voltage.
Also provide a kind of electric water heater, comprise shell, inner bag, be provided with above-mentioned anode bar consumption on it and detect suggestion device simultaneously.
Anode bar consumption detection device provided by the utility model, it is applied to water-heater, has saved anode bar and has been connected setting with the insulation between inner bag, has facilitated installation, has guaranteed that anode bar protects the inner bag sustained current, secondly, be provided with current detection module between anode bar and electric heater, and be serially connected with current-limiting resistance in circuit, this resistance can play the effect of restriction anode bar to the protective current value of electric heater, because liner material is different with the electric heater material, this resistance balance the protection difference of anode bar to this bi-material, make the two protection is all reached to best effect, this resistance value can be according to liner material, the electric heater material, power, the conditions such as temperature, by calculating or experiment, resistance is made to corresponding adjustment, can provide corresponding protection to electric heater, while is consumable anode rod within reason also, and, by this protective current is detected with standard protective current value and compares, judge whether to be changed anode bar and remind, both protected inner bag, guaranteed again the protection to well heater, but improved the working life of entire system, further obtaining of standard protective current value proposed to optimization, the user can select suitable obtain manner according to practical situation, can guarantee to obtain standard protective current value the most accurately, avoid higher or lower than standard protective current value, causing replacing too early or that excessively cause evening improper because of the real protection electric current.
