Abstract
The utility model relates to a water temperature display for a plurality of horizontal regions of an electric water heater, which is composed of a temperature sensor, a signal processing circuit, and a display piece. The utility model is characterized in that the temperature sensor is a sensor set which is composed of a plurality of temperature sensors in two or more than two horizontal regions which are distributed in an inner liner of an electric water heater; the temperature sensor can sense and display the temperature information of a plurality of horizontal regions in the electric water heater. The utility model is suitable for the water temperature display of a sealed electric water heater, and can reflect the cold and hot water ratio variation of the water temperature variation or the preset temperature range of each of the horizontal regions in a container in the course of operation.
Description
The utility model relates to the water temperature display unit of closed electrical water heater.
Electric heater generally adopts enclosed construction, and water inlet directly communicates with running water pipe, and stable in order to guarantee leaving water temperature, its structure satisfies hot and cold water and separates.Though constantly replenish cold water during use, cold water is always in the container bottom, and hot water is on container top, and the ratio of hot and cold water in container is constantly to change.The water temperature display unit of existing water heater can not reflect this dynamic variation intuitively, brings inconvenience to the user, even difficult situation occurs.
The purpose of this invention is to provide the multilevel interval water temperature display unit of a kind of electric heater, thereby reflect in the electric heater water temperature between each horizontal zone intuitively, or show the hot and cold water ratio of one or more design temperature scopes.
The multilevel interval water temperature display unit of this electric heater, form by temperature sensor, signal processing circuit, display device, its special character is that described temperature sensor is by being distributed in inner container of electric water heater, the sensor groups that a plurality of temperature sensors between two or two above horizontal zones constitute.It is sealed by fluid-tight good heat conducting material, and be installed on the inwall of water heater liner different depth, or it is under water as existing electric heater temperature control sensor, also can be installed on the inner bladder outer wall if water heater liner is a good heat conducting material, purpose is in time to reflect water temperature variation between each horizontal zone in the container.
Above-mentioned temperature sensor adopts step change type (switch) temperature sensor, also can adopt analogue type (linearity) temperature sensor.A kind of sensor is used for the hot and cold water ratio of display setting temperature range before adopting, and the latter can be used for showing the actual water temperature between each horizontal zone.
The aforementioned display device part has two kinds of display modes as required, and a kind of mode shows that with digital timesharing actual water temperature between a plurality of horizontal zones, another kind of mode simulate the hot and cold water ratio that shows one or more design temperature scopes.
The representative embodiment of the present invention cooperates circuit block diagram to be illustrated with schematic diagram:
Fig. 1 adopts the analogue type temperature sensor to show the multilevel interval water temperature display unit of electric heater of each interval water temperature and respective bins code name with digital form, for the electric heater with ordinary numbers water temperature display, increase and decrease partly device can realize that water temperature shows between multi-region.
If container is divided between 6 horizontal zones, then sensor groups is by 6 sensors that are distributed between each horizontal zone, and 1,2,3,4,5,6 form, and are encapsulated in the metal tube 7, make its with inner bag in water 8 isolation.Signal processing circuit and display device be by corresponding analog switch 9,10,11,12,13,14, digital temperature display circuit 15, and time-base generator 16, pulsqe distributor 17, counter 18, decoder 19, and interval code name display 20 is formed.The clock pulses that time-base generator 16 produces is sent into pulsqe distributor 17, the time sequential pulse that the generation cycle changes, order is opened analog switch 9,10,11,12,13,14, make the signal of 6 sensor outputs enter digital temperature display circuit 15 successively, order shows water temperature between 6 horizontal zones, clock pulses is sent into counter 18 simultaneously, shows the interval code name of corresponding horizontal by display 20 after decoder 19 decodings, and the variation of the water temperature between each horizontal zone has also just come into plain view in the water heater like this.
Fig. 2 adopts the step change type temperature sensor to show the multilevel interval water temperature display unit of electric heater of the hot and cold water ratio of a certain design temperature scope with analog form.
If container is divided between 4 horizontal zones, then sensor groups is by 4 sensors that are distributed between each horizontal zone, 1,2,3,4 form, signal processing circuit is by corresponding Schmidt circuit 7,8,9,10, phase inverter 11,12,13,14 constitutes, and red, green double color luminotron 15,16,17,18 is used for the hot and cold water of display setting temperature range.If sensor is installed on the metal inner tube outer wall 5, water 6 in container, reach design temperature all the sensors output high level when above, Schmidt circuit 7,8,9,10 is also exported high level, double color luminotron 15,16,17,18, middle red luminotron is bright, phase inverter 11,12,13,14 is output as low level, and the respective green luminous tube does not work.When using hot water, lower floor level interval charges into cold water, sensor 4 output low levels, Schmidt circuit 10 output low levels, phase inverter 14 output high level, double color luminotron 18 become green by redness, at this moment 3 double color luminotrons still are red in addition, illustrate that then hot water also has 3/4.Continue to use hot water, if there are 2 luminous tubes all to become green, 2 is red in addition, illustrates that then the hot water in the water heater has only 2/4 ... reflect the variation of hot and cold water ratio in the water tank so very visually.
