Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, an intelligent control device for supplying hot water by connecting a solar water heater 11 and a gas water heater 21 in parallel comprises two modules, namely a solar water heater module 10 and a gas water heater module 20. The solar water heater module 10 is composed of a solar water heater 11, a first electric two-way valve 123, an intelligent controller 121, a temperature measuring sensor, a temperature measuring tee 122 and the like. The temperature sensor is connected to the intelligent controller 121, and the intelligent controller 121 is composed of two paths of outputs, one path of output controls the first electric two-way valve 123, and the other path of output wireless signal is sent to the wireless control switch 222 of the gas water heater module 20 to control the start and stop of the second electric two-way valve 221.
The gas water heater module 20 consists of a gas water heater 21, a wireless control switch 222 with a wireless receiver and a second electric two-way valve 221.
Installation of the module 10 at the solar water heater:
the solar water heater 11 is generally a pressure-bearing solar water heater. A temperature measuring tee 122, a first electric two-way valve 123 and an original water pipe joint are sequentially arranged along the hot water outlet direction of the solar water heater 11; the water pipe joint is communicated with the hot water pipe 30, and the water inlet of the solar water heater 11 is connected with the cold water pipe 40; and the temperature measuring tee 122 and the first electric two-way valve 123 are connected with the intelligent controller 121, and the intelligent controller 121 is arranged on the side of the water tank by adopting screws. And the joint of each pipeline is sealed by adopting a raw material belt or anaerobic adhesive, so that water leakage is avoided. The power line plug is directly inserted into a 220V three-hole socket with reliable grounding, and the wiring plug of the temperature measuring tee 122 is connected with the plug reserved by the intelligent controller 121 in an opposite-plug mode.
The temperature sensor on the temperature measuring tee 122 is to be inserted into the water tank of the solar water heater. The control line of the electric actuator of the first electric two-way valve 123 is connected with one output terminal in the intelligent controller, and the actuator is installed to be upward or slightly upward horizontally and not downward, so that water leakage at the joint is prevented from entering the actuator to burn out the motor; the intelligent controller 121 must not be installed directly under the water tank to avoid the damage of the circuit board due to the water leakage at the joint.
Mounting of the module 20 at the gas water heater:
the gas water heater 21 is typically a conventional gas fired water heater. Firstly, separating a water pipe joint from the gas water heater 21, butting one end of the second electric two-way valve 221 with a water inlet of the gas water heater 21, butting the other end of the second electric two-way valve with a joint of the cold water pipe 40, connecting a water outlet of the gas water heater 21 with the hot water pipe 30, and sealing by using a raw material belt or anaerobic adhesive; the wireless control switch 222 is installed on one side of the gas water heater by self-tapping screws or double-sided adhesives, and is not installed right below the gas water heater 21, so that the switch is prevented from being damaged by water leakage at the joint, and then a power plug is inserted into a 220V three-hole socket.
Working principle:
the first electric two-way valve 123 of the solar water heater module 10 is normally open, and the second electric two-way valve 221 of the gas water heater module 20 is normally closed. In the case of power failure, only the first electric two-way valve 123 of the solar water heater 11 is opened, and the hot water used is the hot water generated inside the solar water heater 11.
The intelligent controller 121 at the solar water heater 11 detects the water temperature of the water tank in real time by inserting a temperature sensor of the water tank in a power-on state. When the detected water temperature is greater than or equal to the set water temperature, the intelligent controller 121 does not output, and the electric two-way valves at the solar water heater 11 and the gas water heater 21 are in the power-off state, i.e. the first electric two-way valve 123 at the solar water heater 11 is in the valve-on state, and the second electric two-way valve 221 at the gas water heater 21 is in the valve-off state, and in this state, hot water flows from the solar water heater 11 to each water consumption point, as indicated by the arrow pointing in fig. 2.
When the actual water temperature detected by the intelligent controller 121 is lower than the set water temperature, two output terminals are powered on, one output terminal starts to close the first electric two-way valve 123 at the solar water heater 11, and the other output terminal outputs a wireless signal to the wireless control switch 222 of the module 20 at the gas water heater, and the wireless control switch 222 rapidly outputs power so that the second electric two-way valve 221 is rapidly opened. Thus, when the water temperature of the solar water heater 11 cannot meet the requirement, the water valve of the solar water heater 11 is rapidly closed, and the water valve at the gas water heater 21 is synchronously opened. In this state, hot water flows from the gas water heater to each water point as indicated by the arrows in fig. 3.
The solar water heater 11 adopts a split wall hanging pressure-bearing type solar water heater, and the solar water heater 11 can also be replaced by an air energy water heater.
The solar water heater 11 must be a storage type water heater, the temperature sensor on the temperature measuring tee 122 must be inserted into the water tank, the intelligent controller 121 monitors the water temperature in the water tank of the solar water heater 11 in real time in a set starting period, if the set temperature is reached, the second electric two-way valve 221 keeps unchanged in the current state, if the water temperature in the water tank of the water heater is lower than the set value, the intelligent controller 121 immediately outputs, the first electric two-way valve 123 at the solar water heater 11 is closed, and simultaneously the second electric two-way valve 221 at the gas water heater 21 is opened; this operating state is maintained regardless of the use of hot water.
The control system of the present utility model, which is composed of the intelligent controller 121, the first electric two-way valve 123, the temperature measuring three-way valve 122, the second electric two-way valve 221 and the wireless control switch 222, is only a hardware platform composed of physical components connected together by a circuit structure. In use, the intelligent controller 121 may cooperate with software of the prior art to effect monitoring of the first electrically powered two-way valve 123, the temperature tee 122, the second electrically powered two-way valve 221 and the wireless control switch 222, but it must be noted that: the software that cooperates with the present control system is not an innovative part of the present utility model nor is it an integral part of the present utility model.
Under the combined action of the software, the utility model can respectively realize the control of the solar water heater 11 and the gas water heater 21, but the protection of the utility model only extends to a hardware network formed by physical components and wires, and does not relate to the improvement and the protection of the software.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
