Description of drawings
The structural representation of a kind of electric heater that Fig. 1 provides for the utility model embodiment;
The another kind of structural representation of a kind of electric heater that Fig. 2 provides for the utility model embodiment.
The specific embodiment
The utility model embodiment provides a kind of electric heater, and when the top layer water temperature that detects flow signal and inner container of electric water heater when flow sensor was lower than predetermined threshold, this control device cut out bottom heater, starts top heater and heats; And when receiving the control information that the user sets, if flow sensor detects flow signal and inner container of electric water heater top layer water temperature when being higher than predetermined threshold value, this electric heater starts bottom heater or bottom heater alternately heats with top heater.
To combine accompanying drawing below, embodiment is described in detail to the utility model.Referring to Fig. 1; A kind of electric heater that the utility model embodiment provides comprises: top heater 1, bottom heater 2, head temperature sensor 3, inner bag 4, flow sensor 5, control information receiving element (not shown) and first control device and second control device (not shown).
When the user uses electric heater, for example, select to use 40 ℃ of hot water to have a bath; Open the trickle gondola water faucet; At this moment, the hot water that comes out in the trickle gondola water faucet is the hot water that mixes through water-mixing valve, is the hot water that come out by the outlet pipe that links to each other with inner bag 4 and mixed water section in always intaking mixes.Referring to Fig. 1; The part of total water inlet (mixing water) has flow to the trickle gondola water faucet through water-mixing valve; Remaining part gets into inner bag through water inlet pipe, thereby the hot water temperature in the inner bag is changed, in order to keep 40 ℃ of water temperatures of having a bath and using; Just need to regulate water temperature, will increase by the hot water flow that the electric heater outlet pipe comes out so through water-mixing valve.
First control device; Be electrically connected with said top heater 1, bottom heater 2, head temperature sensor 3, flow sensor 5 respectively; When first control device receives the flow signal of flow sensor 5 and the top layer water temperature of the head temperature sensor 3 that received when being lower than predetermined threshold, start top heater 1 and heat.When first control device can make the top layer water temperature of electric heater in detecting inner bag 4 low thus, carry out Fast Heating through top heater 1.Also can adopt in addition alternately to start top heater 1 and heat, use the energy to practice thrift, and prolong the service life of device with bottom heater 2.
Second control device is connected with top heater 1, bottom heater 2, head temperature sensor 3, flow sensor 5 respectively; Whether the top layer water temperature that is used to judge the head temperature sensor 3 that is received is higher than predetermined threshold; For example 75 ℃; When the top layer water temperature that is received was higher than predetermined threshold, control electric heater bottom heater 2 started heating or top heater 1 and alternately heating of bottom heater 2.
Second control device also is connected with the control information receiving element, when receiving the water flow signal that flows through flow sensor 5, and the information of the heat time heating time of setting according to the user of control information receiving element, control electric heater bottom heater 2 starts heating.
The information of this control information receiving element can be set according to operating position, for example, and in the process of having a bath; Know that just the back will increase the number or the bathtime of having a bath; Promptly require in the prolongation process of bathtime coolant-temperature gage to keep constant basically and have a bath to offer the descendant, correspond to setting heat time heating time (preferable, set and be shorter than user's required All Time of having a bath heat time heating time; To utilize the follow-up surplus temperature after heating finishes to continue to have a bath); Can this situation be set at control information, for example, control information be set at 1.
In addition, can also save the energy through setting control information, for example, if the user wants a people to have a bath, it is temperature required to be 45 ℃, existing water heater, and then the user need be heated to the water in the inner bag 55 ℃, to adapt to the progressively decline of water temperature in the process of having a bath.And the electric heater of present embodiment, according to the prolongation of its water time, through using control information; For example, control information is changed to 1, thereby can predetermined threshold be set at 45 ℃; The user can heat in the limit side washing like this; Water heater sustainable heat time heating time that is heated to setting, need water be heated to above 45 ℃ all the time, thereby save the energy.
When flow sensor detects the water flow signal that flows through flow sensor; Detect inner bag top layer water temperature through the head temperature sensor; Even when inner bag top layer water temperature is higher than predetermined threshold, the user also can be through setting control information, and the water storage of inner bag is heated; Can prevent under the very little situation of flow, can't start top heater and cause enough subsequent use hot water can't be provided.
Above embodiment is the technical scheme that the utility model is described with user's bathing water, but the electric heater of the utility model also not only is used to have a bath, for example; The water or be used for the water of washing one's hands of toilet of washing the dishes that can be used as the kitchen is promptly when only needing a small amount of water, according to the top layer water temperature that detects; Determine whether the open top part heater, for example, when only needing a small amount of water; When if the top layer water temperature is higher than predetermined threshold; Close top heater 1 or start bottom heater 2 and heat,, start top heater 1 and carry out Fast Heating if when the top layer water temperature is lower than predetermined threshold.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; For example, can the module of difference in functionality be realized etc. through an integrated chip, all within the spirit and principle of the utility model; Any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
