Description
The present invention relates to a kind of positive displacement electric heater, thereby particularly a kind of has intelligent type energy saving electric water heater microcomputer controller, that can heat in advance for the user automatically by the analysis user laws of use.
At present, electric heater has become a kind of household electrical appliance of quite popularizing.Existing electric heater all by housing, be installed in inner bag in the housing, be fixed on the electroheat member in the inner bag, the control circuit that is connected with the electroheat member power take-off and Inlet and outlet water device and form.Its circuit control content is fairly simple usually, and simple temperature control action is played in the temperature-responsive of only user being set that has, and is with water temperature control in the courage within the specific limits; The timing function that only possesses three periods that has, and can not hot-water supply in the non-water supply period, the user often needs manual operation control water heater, uses very inconvenient.
The patent No. is to disclose a kind of comparatively advanced electric heater that contains microcomputer control circuit in the BP " Control Circuit for aLoad " of GB2290152.The microcomputer control circuit of this water heater can be according to preset program, realize the automatic control of water temperature, water level, but it can not carry out Based Intelligent Control according to each user's concrete operating position, can not accomplish the electric energy that can also practice every conceivable frugality when satisfying the specific instructions for use of each user.
We know for same positive displacement electric heater, if water temperature is high more in the inner bag, then heat dissipation capacity is big more in the unit interval, and in the existing product, the inner bag water temperature remains on user's design temperature always or water heater is heated in the certain limit of maximum temperature, when the user does not need to use hot water in a large number, water temperature is remained on higher temperature for a long time will cause unnecessary energy loss so.Face today of energy crisis the mankind, existing electric heater does not consider that energy-conservation this weak point day by day looms large, to when should cause enough attention.
The objective of the invention is, overcome the above-mentioned weak point of prior art, design a kind of intelligent type energy saving electric water heater, this water heater can be grasped user's laws of use by the analysis user operating position, thereby water temperature is controlled in the low scope in the non-water period that micro computer is judged, before the water that micro computer is judged arrives constantly, heats in advance for the user automatically.
Overall design philosophy of the present invention is, microcomputer controller is constantly learnt the practical experience that the user uses water heater by the cycle, monitor by sample circuit, obtain water temperature rate of change information in the inner bag, the change information of one-period is noted the line data operational analysis of going forward side by side, obtain the data message that this user uses the water heater rule, again according to the data message and the built-in design temperature of gained watering law, user's design temperature, the mode of operation that these three design temperatures of the highest design temperature and user select is carried out Based Intelligent Control to the heating work of water heater: under intelligent mode, carry previous time quantum constantly at the water of micro computer judgement and be heated to user's design temperature, in the non-water moment that micro computer is judged, be the temperature control value with lower built-in design temperature; Under manual mode, be the temperature control value with user's design temperature; Under timing mode, start water heater in the low electricity price period (being set by the user) that micro computer is judged and be heated to the highest design temperature, otherwise be the temperature control value with lower built-in design temperature.By above-mentioned Based Intelligent Control, reach saves energy and the purpose that is user-friendly to greatest extent.
Concrete technical scheme of the present invention is as follows: a kind of intelligent type energy saving electric water heater, its composition comprises housing, inner bag, electroheat member, microcomputer controller, the power output block, microcomputer controller comprises central processing unit U1, the power circuit that is electrically connected with central processing unit, sample circuit, temperature setting circuit, button inputting circuits, display output circuit, drive circuit, has analog-digital commutator among the U1, time set, counting device, storing apparatus, comparison means, arithmetic unit, input/output unit is characterized in that also having among the U1: 1, be used for to sample circuit, storing apparatus, comparison means, arithmetic unit provides the relevant work time interval, the timing means of measuring heat time heating time in advance is provided to the heat driven circuit; 2, be used to store the storing apparatus of sampled data rate of change setting value and be used to store the storing apparatus of rule operation result setting value; 3, be used for current sampled data rate of change value and setting value compares, if currency more than or equal to the setting value with " 1 " output otherwise with " 0 " output comparison means; 4, be used for writing down comparison means output of corresponding period of one-period result's storing apparatus; 5, be used for taking out stored data group of corresponding period of storing apparatus carry out certain rule computing, if the operation result value more than or equal to the setting value then with " 1 " output, otherwise with " 0 " output arithmetic unit; 6, be used for writing down arithmetic unit output of corresponding period of one-period result's storing apparatus; 7, be used for when exporting high level otherwise the input/output unit of output low level to drive circuit to heat time heating time in advance that timing means limits and corresponding period operation result storing apparatus control data during for " 1 ".
Also have among the U1 of the present invention be used for storing respectively built-in set temperature value, user's set temperature value, the highest set temperature value storing apparatus and be used for storing respectively the storing apparatus of intelligent mode code, manual mode code, user's setting-up time value.The user can select mode of operation or set the low electricity price period by button inputting circuits, also can set required heating-up temperature by temperature setting device.
Hardware device of the present invention fully is used in combination with software program, the situation information that the time interval that sample circuit in the microcomputer controller provides by timer is gathered user's water, work by comparison means and arithmetic unit, obtain " 0 ", " 1 " control data of the corresponding period use of this user water heater rule in the one-period, then this water heater working is carried out Based Intelligent Control: water temperature is controlled in the low scope in the non-water period that micro computer is judged, before the water that micro computer is judged arrives constantly, heats in advance in appropriate.Like this, electric heater of the present invention can be learnt user's water experience intelligently, control water heater working intelligently, avoid when not using the also phenomenon of high temperature heating, thereby reduce the meaningless thermal losses of water heater self to greatest extent, the saves energy effect is obvious, the Based Intelligent Control function is strong, increases cost hardly, and is easy to use, economical and practical, fully satisfy user's needs.
