Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
Referring to fig. 1, the gas water heater of the embodiment of the invention comprises a shell 1, a proportional electromagnetic valve 2 arranged in the shell 1, a distributor 3, a combustion system 4, a smoke collecting hood 5, a control unit 6, a fan 7, a water inlet pipeline 8, an electromagnetic valve 12, a water outlet pipeline 10, a water inlet joint 11, a water outlet joint 12 and a gas inlet joint 13 arranged outside the shell 1.
The combustion system 4 comprises a burner 41 and a heat exchanger 42. An inlet of the combustor 41 is sequentially connected with a distributor 3 and a proportional solenoid valve 2, the proportional solenoid valve 2 is used for controlling the amount of gas entering a combustion chamber, and the distributor 3 is used for distributing the gas provided by the proportional solenoid valve 2 to a corresponding fire row in the combustor 41; the outlet of the burner 41 is connected with the flue inlet of the heat exchanger 42, the flue outlet of the heat exchanger 42 is connected with the inlet of the smoke collecting hood 5, the outlet of the smoke collecting hood 5 is communicated with the external air, the smoke collecting hood 5 is connected with the fan 7, the fan 7 is used for sucking the external air into the burner 41, and the smoke generated by the burner 41 is pumped out of the smoke collecting hood 5. An ignition needle is provided in the burner 41, and the ignition needle is used to ignite the mixed gas in the burner 41. Water lines in the heat exchanger 42 communicate between the water inlet line 8 and the water outlet line 10.
The control unit 6 is configured to: when receiving the opening signal, controlling the electromagnetic valve 12 to be in an opening state; controlling the combustion system 4 to be in a running state; acquiring an operation parameter value of the gas water heater; judging whether the operation parameter value meets a preset value; when it is determined that the operating parameter value satisfies the preset value, the control solenoid valve 12 is in a closed state.
Referring to fig. 2, the operation flow of the gas water heater according to some embodiments of the present invention is as follows:
when the control unit 6 receives the opening signal, the control electromagnetic valve 12 is opened, cold water flows into a water pipeline of the heat exchanger 42 from the water inlet joint 11 through the water inlet pipeline 8, meanwhile, the control unit 6 controls the proportional electromagnetic valve 2 to be opened and controls the ignition needle to ignite, if the ignition is not successful, the control unit 6 controls the proportional electromagnetic valve 2 to be opened again and controls the ignition needle to ignite; if the ignition is successful, the combustion system 4 is continuously operated, the cold water entering the water pipeline of the heat exchanger 42 exchanges heat with the smoke generated by the burner 41 in the heat exchanger 42, and the heated hot water flows out from the water outlet joint 12 through the water outlet pipeline 10.
After the burner 41 in the gas water heater operates, the control unit 6 obtains the operation parameter value of the gas water heater and judges whether the operation parameter value meets the preset value, when the operation parameter value meets the preset value, the electromagnetic valve 12 is controlled to be in a closed state, at this time, cold water entering the gas water heater is shut down, and water outlet of the gas water heater stops. The gas water heater provided by the embodiment of the invention can realize automatic water shutoff and can avoid the phenomenon of water overflow.
In some embodiments, after determining whether the operating parameter value meets the preset value, the control unit 6 is further configured to: and if the operation parameter value meets the preset value, sending an alarm signal. Therefore, when the operation parameter value meets the preset value, the control unit 6 can send out an alarm besides automatically closing water inlet, for example, a buzzer is controlled to buzz to remind a user that water inlet is closed, and if the user is busy with other things at the moment, the alarm can play a role in reminding the user.
Since the electromagnetic valve 12 is in a closed state after the operation parameter value meets the preset value, the electromagnetic valve is opened again when the user needs to use the device again. Because the gas water heater is generally arranged in a kitchen, if a user finds that the electromagnetic valve 12 is in a closed state during bathing, the user needs to go to the kitchen to start the gas water heater so as to open the electromagnetic valve 12, and the operation is very inconvenient.
Based on the above situation, in some embodiments, a communication function is added to the gas water heater, that is, a receiving module of the wireless communication module is installed in the gas water heater, and a transmitting module (terminal) of the wireless communication module is arranged at the water using position; the receiving module of the wireless communication module is in communication connection with the control unit 6 and the transmitting module of the wireless communication module; after controlling the solenoid valve 12 in the closed state, the control unit 6 is further configured to: when the receiving module of the wireless communication module receives the signal sent by the transmitting module of the wireless communication module, the receiving module of the wireless communication module feeds back the information to the control unit 6; when the control unit 6 receives the information fed back by the receiving module of the wireless communication module, the electromagnetic valve 12 is controlled to be in an open state.
Specifically, the receiving module of the wireless communication module can be WIFI, the terminal can be a mobile phone, and the like, when the electromagnetic valve 12 needs to be opened, an instruction for opening the electromagnetic valve 12 is initiated on the mobile phone, so that the electromagnetic valve 12 can be remotely opened, and the operation is very convenient.
When the weather is particularly cold in winter, if the gas water heater is not plugged, the anti-freezing device cannot play a role in electric heating and freezing prevention, the pipeline inside the gas water heater can be frozen and cracked, the gas water heater is directly communicated with the main household water channel, once the pipeline inside the gas water heater is damaged, water in the main household water channel flows outwards through the damaged pipeline, excessive overflowing water can be caused if a user does not find the water in time, and even furniture can be damaged.
In this regard, in some embodiments, the solenoid valve 12 is a normally closed solenoid valve and is disposed at the water inlet of the water inlet line 8 of the gas water heater. Specifically, the electromagnetic valve 12 may be a waterway intelligent electromagnetic valve, the front end of the electromagnetic valve 12 is connected to the water inlet joint 11, and the rear end is connected to the heat exchanger 42. Because the electromagnetic valve 12 is a normally closed valve, this structure can ensure that, once the anti-freezing device fails, when the water inlet pipeline 8 (generally, copper pipe) or the water outlet pipeline 10 (generally, copper pipe) of the gas water heater is frozen and cracked, the gas water heater does not leak water of the main pipeline inside the household through the cracked pipeline inside the gas water heater.
The functions of the existing gas water heaters are more and more, for example, for people who use bathtubs for bathing, some gas water heaters are specially provided with a bathtub mode. In order to facilitate the control of the time for injecting hot water into the bathtub, most of the gas water heaters of the type have the function of detecting the accumulated water injection amount, namely, when the water injection amount reaches a set value, a user is reminded to timely close a water outlet valve of the gas water heater through the sound of a buzzer. However, if the user is not at home or is busy doing other things at the moment and the water outlet valve of the gas water heater is not closed in time, the water in the bathtub is injected too much, and even water overflow occurs.
In some embodiments, the operating parameter value may be an accumulated water injection amount, and the predetermined value may be satisfied when the accumulated water injection amount reaches a predetermined water injection amount. The preset water injection amount can be a value set artificially, such as 20L or 30L. The control unit 6 may be specifically configured to: when receiving the opening signal, controlling the electromagnetic valve 12 to be in an opening state; acquiring the accumulated water injection amount of the gas water heater; controlling the combustion system 4 to be in an operating state; judging whether the accumulated water injection amount reaches a preset water injection amount or not; when it is determined that the accumulated water injection amount reaches the preset water injection amount, the control solenoid valve 12 is in a closed state. Therefore, the embodiment of the invention can be used for quantitatively injecting water into the bathtub, and can automatically turn off the water after reaching the preset water injection amount, thereby effectively avoiding the phenomenon that the water is overflowed due to excessive water injection into the bathtub.
There are many available acquisition modes for accumulated water injection amount, and in some embodiments, a water flow sensor 9 may be disposed on the water outlet pipeline 10, which has the disadvantage that, because the combustion system 4 is ignited, it needs to detect that water flows through the pipeline first, and therefore, a sensor for detecting that water flows through, such as an ultrasonic sensor, is also disposed on the water inlet pipeline 2, and at least two sensors are needed, which results in a complex structure and higher cost. In other embodiments, referring to fig. 1, a water flow sensor 9 may be disposed on the water inlet pipeline 8, and the water flow sensor 9 may feed information of water flow passing through the pipeline back to the control unit 6 when water flow passes through the pipeline, so that the control unit 6 controls the start of the combustion system 4, and may feed a flow value of the pipeline back to the control unit 6, so that the control unit 6 accumulates water injection amount, thereby simplifying the structure and reducing the cost. Therefore, the water flow sensor 9 is preferably provided in the water inlet line 8.
Because the gas water heater is easy to damage after continuously burning for a long time, and carbon monoxide can be generated due to insufficient oxygen supply to harm the health of users, the existing gas water heaters have the function of automatically closing a burning system after burning for a certain time (such as 20 min-60 min), however, cold water can still continuously enter the gas water heater and flows out through the gas water heater after the burning system is closed, and at the moment, if the users take a bath, the users are likely to feel uncomfortable due to too cold water; if the user forgets to close the outlet valve or the outlet valve fails, the user may not find it in time, which may cause water overflow.
In this case, in some embodiments, the operation parameter may be a combustion duration, and the meeting of the preset value may be that the combustion duration reaches the preset duration. The control unit 6 may be specifically configured to: when receiving the opening signal, controlling the electromagnetic valve 12 to be in an opening state; controlling the combustion system 4 to be in a running state; acquiring the burning time of the gas water heater; judging whether the burning time reaches a preset time; when it is determined that the combustion period reaches the preset period, the control solenoid valve 12 is in a closed state.
The preset time period may be a value set manually, such as 20min or 30 min. The value can be equal to the time length of the automatic closing of the combustion system 4 of the gas water heater, the automatic closing of the combustion system 4 of the gas water heater can automatically close water inlet at the same time, and the phenomenon that water is suddenly cooled when a user bathes can be avoided, so that discomfort is brought to the user. This value may also be less than the length of time that the gas water heater automatically shuts down the combustion system 4 to prevent the creation of water spills.
There are various ways to obtain the combustion duration, and in some embodiments, a temperature sensor may be provided in the combustion system 4, and when the combustion system 4 starts to operate and the temperature near the temperature sensor reaches a set value, the temperature sensor sends a signal to the control unit 6, and the control unit 6 starts to accumulate the combustion duration. This configuration has the disadvantage that the measurement has a certain error, since it takes a certain time until the temperature in the vicinity of the temperature sensor reaches the set value after the combustion system 4 starts to ignite. In other embodiments, a sensing needle may be provided in the combustion system 4, the sensing needle is used for sensing whether there is a flame in the burner 41, when the sensing needle senses that there is a flame in the burner 41, the sensing needle sends a signal to the control unit 6, and the control unit 6 starts to accumulate the combustion time. Thereby, the detection accuracy can be improved. Therefore, the combustion system 4 is preferably provided with an induction needle.
After the gas water heater is installed, the gas water heater is firstly powered on, and then the gas water heater is started. It should be noted that, in general, the gas water heater does not need to be turned off after being turned on, but the gas water heater needs to be turned off if the gas water heater is not used for a long time, or even power is cut off.
The embodiment of the invention also provides a control method of the gas water heater, which can be applied to the gas water heater shown in the figure 1.
Referring to fig. 3, a control method of a gas water heater provided by an embodiment of the invention may include: steps S101-S106.
S101, a control unit receives an opening signal and controls an electromagnetic valve to be in an opening state;
s102, controlling a combustion system to be in an operating state by a control unit;
s103, the control unit acquires the operation parameters of the gas water heater;
s104, judging whether the operation parameter value meets a preset value by a control unit; if yes, go to step S105; if not, step S103 is executed.
And S105, the control unit controls the electromagnetic valve to be in a closed state and sends out an alarm signal.
Step S106 may be optionally performed after step S105.
And S106, the control unit controls the gas water heater to stop running.
Step S107 may be optionally performed after step S106.
S107, a transmitting module in the wireless communication module sends a signal to a receiving module in the wireless communication module, and the receiving module in the wireless communication module feeds back information to the control unit; and when the control unit receives the information fed back by the receiving module in the wireless communication module, the control unit controls the electromagnetic valve to be in an open state.
In order to more clearly describe the above scheme, two specific examples are described below.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
