[0039] The present disclosure will be further described by way of examples without limiting the present disclosure to the described examples.

[0040] Example 1

[0041] The present disclosure provides a control method of a gas water heater, which comprises the following steps, referring to Figure 1 :

[0042] Step 101, obtaining an operating parameter of the gas water heater.

[0043] The operating parameter can include, but is not limited to, a set temperature of the gas water heater, a water flow, an actual yield, a working position of a proportional valve arranged on a gas pipeline, a working current of the proportional valve arranged on the gas pipeline, and a water outlet temperature.

[0044] The set temperature is a temperature set by a user according to a demand, so as to match the water outlet temperature of the gas water heater with the set temperature.

[0045] Referring to Figure 2The water flow rate is detected by a water flow sensor 3 arranged on the water inlet pipeline 1 of the gas water heater. It should be noted that the water flow sensor 3 can be arranged on the water outlet pipeline 2 of the gas water heater to detect the water flow rate of the water outlet. Figure 2 The water inlet pipeline 1 shown in the figure can be used to detect the water flow rate of the water inlet; the water outlet pipeline 2 of the gas water heater can also be used to detect the water flow rate of the water outlet; the embodiments of the present disclosure do not make special limitations on this.

[0046] The water inlet temperature is detected by a temperature sensor 41 arranged on the water inlet pipeline 1 of the gas water heater; the water outlet temperature is detected by a temperature sensor 42 arranged on the water outlet pipeline 2 of the gas water heater. The operating temperature of the gas water heater can be detected by a temperature sensor 43 arranged on the heat exchanger 5.

[0047] The proportional valve 6 is arranged on the gas pipeline 7, and the actual yield is determined by obtaining the working position and working current of the proportional valve 6. Specifically, the test data containing the working position, working current and actual yield are fitted to obtain the corresponding relationship among the three, and the actual yield matched with the current working position and working current of the proportional valve 6 can be determined according to the corresponding relationship.

[0048] It should be noted that for different models of gas water heaters, the corresponding relationship among the working position, working current and actual yield is different, so the corresponding relationship matched with different models of gas water heaters needs to be obtained according to the test data of different models of gas water heaters. The corresponding relationship can be but not limited to characterized by a function, a table or a model.

[0049] In addition, Figure 2 In addition to the above operating parameters, the conventional operating principle of the gas water heater is also shown in the figure, for example, the gas water heater also includes a fire grate 8 and an ignition needle 9, the ignition needle 9 is used for ignition, and the fire grate 8 is used for burning the gas delivered by the gas pipeline 7. The actual yield of the gas water heater can be determined by obtaining the operating parameters of the proportional valve 6, which is only an example and can be selected according to the actual situation, and the water heater is not particularly limited herein.

[0050] In step 102, the water inlet temperature of the gas water heater is calculated according to the operating parameters.

[0051] The calculated water inlet temperature sensor can be used to calculate the target yield of the gas water heater, and then control the operation of the gas water heater.

[0052] In the embodiment, the water inlet temperature of the gas water heater can be directly obtained by the above steps, and the water inlet temperature sensor in the conventional gas water heater structure can be omitted, which not only saves the development cost, but also saves the maintenance cost of the water inlet temperature sensor.

[0053] In one embodiment, when the running parameters include the set temperature, the water flow and the actual yield, step 102 specifically includes: calculating the water inlet temperature of the gas water heater according to the set temperature, the water flow and the actual yield.

[0054] The calculation formula of the water inlet temperature can be but is not limited to expressed as follows:

[0055]

[0056] In the embodiment, by inversely deducing the water inlet temperature according to the actual yield, not only the calculation complexity is low, but also the estimation accuracy of the water inlet temperature is improved.

[0057] In one embodiment, when the running parameters include the set temperature, the water flow, the working gear and the working current, referring to Figure 3 , step 102 specifically includes:

[0058] Step 301, obtaining the set temperature, the water flow, the working gear and the working current from the running parameters;

[0059] Step 302, determining the actual yield according to the working gear and the working current of the gas water heater.

[0060] Step 303, calculating the water inlet temperature of the gas water heater according to the set temperature, the water flow and the actual yield of the gas water heater.

[0061] In one embodiment, before the step of obtaining the running parameters of the gas water heater, it is judged whether the gas water heater is in the working state; when the judgment result is yes, the step of obtaining the running parameters of the gas water heater is executed. When the judgment result is no, under certain conditions, the outlet water temperature can be directly taken as the estimation value of the water inlet temperature.

[0062] Specifically, when the gas water heater is in the non-working state, if the water flow appears and the water flow lasts for more than a time threshold t1, it is considered that the outlet water temperature and the water inlet temperature are almost the same, at this time, the outlet water temperature is taken as the estimation value of the water inlet temperature, and there is no need to obtain the running parameters of the gas water heater to calculate the water inlet temperature.

[0063] The time threshold t1 can be determined according to the actual situation, can be an empirical value, for example, set to 10s; the time threshold t1 can be dynamically determined according to the water flow, the time threshold t1 is negatively correlated with the water flow, the water flow is small, and t1 is relatively large, the water flow is large, and t1 is relatively small, and the time threshold t1 can be theoretically calculated according to the size of the water flow and the length of the water path in the gas water heater.

[0064] When the gas water heater is switched from the last running state to the non-working state, if the outlet water temperature is maintained for more than a time threshold t2, it is indicated that the outlet water temperature is almost the same as the inlet water temperature, and the value of the outlet water temperature sensor is taken as the estimated value of the inlet water temperature, without obtaining the running parameters of the gas water heater to calculate the inlet water temperature.

[0065] The time threshold t2 can also be selected according to actual conditions, and can be an empirical value, for example, 30 min.

[0066] When the gas water heater is in the working state and is maintained for more than a time threshold t3, the step of obtaining the running parameters of the gas water heater (step 101) is performed, and the inlet water temperature of the gas water heater is calculated according to the running parameters of the gas water heater (step 102).

[0067] The time threshold t3 can also be selected according to actual conditions, and can be an empirical value, for example, 5-10 s.

[0068] In this embodiment, the estimation of the inlet water temperature is different according to different states of the gas water heater, so that the estimated value of the inlet water temperature is more accurate.

[0069] In one embodiment, before the step of obtaining the running parameters of the gas water heater, it is further determined whether the collected data of the inlet water temperature is obtained. If the collected data of the inlet water temperature is obtained, it is indicated that the inlet water temperature sensor is arranged on the gas water heater, and the collected data of the inlet water temperature sensor is directly used to determine the inlet water temperature, without obtaining the running parameters of the gas water heater to calculate the inlet water temperature. If the collected data of the inlet water temperature is not obtained, it is indicated that the inlet water temperature sensor is not arranged on the gas water heater or the inlet water temperature sensor is faulty, and the step of obtaining the running parameters of the gas water heater is performed to calculate the inlet water temperature of the gas water heater according to the running parameters.

[0070] In this embodiment, the scheme of arranging the inlet water temperature sensor in the conventional structure of the gas water heater on the market is compatible. When the inlet water temperature sensor is normal, the collected data of the inlet water temperature sensor is directly used, and the calculation amount is small. When the inlet water temperature sensor is faulty, the inlet water temperature is calculated by using steps 101 and 102, so that even if the inlet water temperature sensor is faulty, the inlet water temperature can be obtained accurately, and the normal running of the gas water heater is ensured.

[0071] In the scene of arranging the inlet water temperature sensor, the inlet water temperature sensor is an external inlet water temperature sensor, thereby providing convenience for the maintenance of the gas water heater.

[0072] In one embodiment, after step 102, it further includes: determining the target yield according to the inlet water temperature and the set temperature, and controlling the running of the gas water heater according to the target yield.

[0073] The control process of the gas water heater is further described below. Figure 4 The control process of the gas water heater is further described below.

[0074] After power-on, the gas water heater is first initialized, and then it is determined whether the acquisition data of the water inlet temperature is obtained. If the acquisition data of the water inlet temperature is obtained, the target yield is directly determined according to the obtained water inlet temperature and the set temperature; if the acquisition data of the water inlet temperature is not obtained, the step of obtaining the running parameter of the gas water heater is performed, and the water inlet temperature of the gas water heater is calculated according to the running parameter, and then the target yield can be determined according to the water inlet temperature and the set temperature. After the target yield is obtained, the PID (Proportion Integral Differential) constant temperature algorithm is applied to control the work of the gas water heater, so that the gas water heater is maintained at the set temperature.

[0075] In the embodiment, the water inlet temperature is estimated according to the running parameter of the gas water heater, which replaces the water inlet temperature sensor in the structure of the conventional gas water heater, and is a scheme in which software implementation calculation replaces hardware equipment, thereby reducing the production cost and the development cost, and reducing the maintenance cost of the built-in temperature sensor.
