Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority to Chinese Patent Application Serial No. 201711479483.8, filed on December 29, 2017 , the entire content of which is incorporated herein by reference.

FIELD

The present disclosure relates to the field of gas water heater technology, and more particularly to a parametric code transformation method for a gas water heater, a non-transitory computer readable storage medium, a parametric code transformation apparatus for a gas water heater and a gas water heater.

BACKGROUND

In general, a default parametric code of a gas water heater is set with natural gas as gas supply. However, the gas supply in some families may be liquefied gas. Therefore, it needs to transform the parametric code according to the gas supply for the gas water heater.
Due to the larger difference of heat values between gas supplies, there are many parametric codes needed to be adjusted, such as a proportional valve maximum secondary pressure code, a maximum wind speed code and a proportional valve minimum secondary pressure code. For ordinary installers, due to the high level of complexity, adjustment errors are prone to occur, and the costs and time to complete such adjustment training are high.
In the related art, the parametric codes between gas supplies, in general, are switched automatically by a gas supply dial switch. For the same model of gas water heaters, the parametric code corresponding to the liquefied gas is preset in the gas water heater. When the gas supply for the gas water heater is changed, the parametric code may be directly switched by dialing the gas supply dial switch. For example, for a gas water heater with the natural gas being defaulted as the gas supply, when the gas supply is the natural gas, the maximum secondary pressure code is C1, when the gas supply is the liquefied gas, the maximum secondary pressure code is C9, and the switch between the two parametric codes can be completed by dialing the gas supply dial switch.
By the above method, when the gas supply for the gas water heater is changed from the natural gas to the liquefied gas, the parametric codes of the gas water heaters with the same model are the same. However, components, such as proportional valves and fans, of different gas water heaters have some differences to a certain extent, even they have the same model. Therefore, the parametric code transformation by the above method may cause problems, for example, the output of the gas water heater goes beyond the deviation specification, the smoke exceeds a specified range, and the ignition fails, thereby affecting working performance of the gas water heater.

DETAILED DESCRIPTION

Reference will be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. The same or similar elements and the elements having same or similar functions are denoted by like reference numerals throughout the descriptions. The embodiments described hereinafter with reference to drawings are explanatory, illustrative, and used to generally understand the present disclosure. The embodiments shall not be construed to limit the present disclosure.
Description will be made hereinafter to a parametric code transformation method for a gas water heater, a non-transitory computer readable storage medium, a parametric code transformation apparatus for a gas water heater and a gas water heater according to embodiments of the present disclosure with reference to the accompanying drawings.
Fig. 1 is a flow chart showing a parametric code transformation method for a gas water heater according to an embodiment of the present disclosure. The gas water heater includes a gas supply dial switch. As shown in Fig. 1, the parametric code transformation method includes the following steps:

At S1, dial state information of the gas supply dial switch is acquired, and a gas supply for the gas water heater is determined according to the dial state information. The gas supply for the gas water heater includes natural gas and liquefied gas.
At S2, a parametric code of the gas water heater is transformed into a first parametric code when the gas supply is the natural gas.
At S3, a parametric code difference value is acquired, and the parametric code of the gas water heater is transformed into a second parametric code according to the first parametric code and the parametric code difference value when the gas supply is the liquefied gas.

In embodiments of the present disclosure, the parametric code of the gas water heater is defaulted to be the first parametric code.
In specific, the gas supply dial switch generally includes a first position and a second position, each of which corresponds to a dial code (1 and 2). There is a silkscreen on the gas supply dial switch, and the user could choose the gas supply for the gas water heater by dialing the silkscreen to a corresponding position. For instance, when the gas supply for the gas water heater is the natural gas, the gas supply dial switch is dialed to the first position, and when the gas supply for the gas water heater is the liquefied gas, the gas supply dial switch is dialed to the second position. The gas supply for the gas water heater is generally the natural gas, and thus the gas supply dial switch of the gas water heater, when leaving the factory, may be dialed to the position corresponding to the natural gas by default.
After the gas supply for the gas water heater is determined according to dial state information, if the gas supply for the gas water heater is the natural gas, the parametric code of the gas water heater is transformed into a parametric code (i.e., the first parametric code) corresponding to the natural gas; if the gas supply for the gas water supply is the liquefied gas, the parametric code difference value is acquired, and the parametric code of the gas water heater is transformed into the second parametric code according the first parametric code and parametric code difference value, in which the second parametric code equals to the first parametric code minus the parametric code difference value. Therefore, the method transforms the parametric code according to the first parametric code and the parametric code difference value when the gas supply for the gas water heater is changed to liquefied gas, thereby effectively making up the errors of components among the gas water heaters and further effectively ensuring the working performance of the gas water heater.
It should be understood that the first parametric code and the parametric code difference value may be preset in the gas water heater before the gas water heater leaves the factory.
In embodiments of the present disclosure, the parametric code may include: a proportional valve maximum secondary pressure code, a maximum wind speed code, a proportional valve minimum secondary pressure code, a minimum wind speed code, a proportional valve ignition secondary pressure code and an ignition wind speed code.

For example, as shown in Table 1 and taking a gas water heater as an example, the parametric code (the second parametric code) when the gas supply is the liquefied gas is equal to the parametric code (the first parametric code) corresponding to the case when the gas supply is the natural gas minus the parametric code difference value.

Table 1

Parametric Code	Natural Gas	Parametric Code Difference Value	Liquefied Gas
Dial state information
PH (Proportional Valve Maximum Secondary Pressure)	99	10	89
FH (Maximum Wind Speed)	89	16	73
PL (Proportional Valve Minimum Secondary Pressure)	45	13	32
FL (Minimum Wind Speed)	32	6	2C
DH (Proportional Valve Ignition Secondary Pressure)	35	7	2E
DF (Ignition Wind Speed)	25	5	20

In embodiments of the present disclosure, the parameter code is a hexadecimal number, and each parameter code corresponds to a working parameter.
As shown in Table 1, the parametric code corresponding to the liquefied gas is related to the parametric code corresponding to the natural gas and the parametric code difference value. As shown in Table 1, the PH corresponding to the natural gas defaulted by the gas water heater is 99, then when the gas supply is changed to the liquefied gas, the corresponding PH is equal to 89, i.e., the corresponding PH=99-10=89. For the gas water heaters with the same model, due to the difference of the components, the first parametric code for each gas water heater may be slightly different. For example, for a gas water heater with the same model as the gas water heater shown in Table 1, if the default PH corresponding to the natural gas is 98, then when the gas supply is changed to the liquefied gas, the corresponding PH is equal to 88, i.e., the corresponding PH=98-10=88.
As can be seen from the above embodiments, when the gas supply for the gas water heater is changed from the natural gas to the liquefied gas, the parametric code needs to be transformed, and the parametric code difference value needs to be acquired for the transformation of the parametric code. In the following, how to acquire the parametric code difference value will be described with reference to the specific embodiments.
According to an embodiment of the present disclosure, as shown in Fig. 2, the parametric code difference value is acquired by the following step.
At S31, first optimal parametric codes for a plurality of gas water heaters when supplied with natural gas and second optimal parametric codes for the plurality of the gas water heaters when supplied with liquefied gas are acquired respectively. In an embodiment, the phrase "a plurality of' generally refers to 10 or more.
At S32, a difference value between the first optimal parametric code and the second optimal parametric code for each of the plurality of the gas water heaters when respectively supplied with natural gas and liquefied gas are calculated.
At S33, an average value of the difference values is calculated and the average value is taken as the parametric code difference value.
Specifically, before leaving the factory, at least 10 gas water heaters with the same model are tested. For each of the at least 10 gas water heaters, the first optimal parametric code is tested when the gas supply is the natural gas, the second optimal parametric code is tested when the gas supply is the liquefied gas, and the difference value between the first optimal parametric code and the second optimal parametric code is calculated. Then, the average value of the respective difference values of the at least 10 gas water heaters is calculated and taken as the parametric code difference value. For example, an optimal PH (natural gas) of a gas water heater is A3, and an optimal PH (liquefied gas) of the gas water heater is 98, and thus a difference value therebetween is 11. In the similar way, the difference value of the PH values can be obtained for each of other gas water heaters. Then, an average value of all the difference values corresponding to the PH is calculated and taken as the parametric code difference value corresponding to the PH of the gas water heaters. Similarity, the respective parametric code difference values corresponding to other parametric codes, such as FH, PL, FL, DH or DF, may be obtained. Finally, all the parametric code difference values are preset in the gas water heater, such that the parametric code may be transformed when the gas supply for the gas water heater is changed from the natural gas to the liquefied gas, thereby making up the differences of components among gas water heaters.
In conclusion, with the parametric code transformation method for a gas water heater according to embodiments of the present disclosure, the dial state information of the gas supply dial switch is acquired first, and the gas supply for the gas water heater is determined according to the dial state information; when the gas supply is the natural gas, the parametric code of the gas water heater is transformed into the first parametric code; when the gas supply is the liquefied gas, the parametric code difference value is acquired, and the parametric code of the gas water heater is transformed into the second parametric code according to the first parametric code and the parametric code difference value. Therefore, the parametric code is transformed according to the parametric code difference value when the gas supply for the gas water heater is changed, and thus the errors of components among gas water heaters can be effectively made up and the working performance of the gas water heater can further be effectively ensured.
Embodiments of the present disclosure also provide a non-transitory computer readable storage medium having stored therein a computer program that, when executed by a processor, causes the processor to implement the parametric code transformation method for a gas water heater as described in embodiments of the present disclosure hereinbefore.
With the non-transitory computer readable storage medium according to embodiments of the present disclosure, the dial state information of the gas supply dial switch is acquired first, and the gas supply for the gas water heater is determined according to the dial state information; when the gas supply is the natural gas, the parametric code of the gas water heater is transformed into the first parametric code; when the gas supply is the liquefied gas, the parametric code difference value is acquired, and the parametric code of the gas water heater is transformed into the second parametric code according to the first parametric code and the parametric code difference value, thereby effectively making up errors of the components among gas water heaters and effectively ensuring the working performance of the gas water heater.
Fig. 3 is a block diagram of a parametric code transformation apparatus for a gas water heater according to an embodiment of the present disclosure. As shown in Fig. 3, the gas water heater includes a gas supply dial switch 100, and the parametric code transformation apparatus includes: an acquiring module 10, a determining module 20 and a parameter transforming module 30.
Among others, the acquiring module 10 is connected to the gas supply dial switch 100, and configured to acquire dial state information of the gas supply dial switch 100. The determining module 20 is connected to the acquiring module 10, and configured to determine a gas supply for the gas water heater according to the dial state information. The gas water heater includes natural gas and liquefied gas. The parameter transforming module 30 is connected to the determining module 20, and configured to transform a parametric code of the gas water heater into a first parametric code when the gas supply is the natural gas; and configured to acquire a parametric code difference value, and transform the parametric code of the gas water heater into a second parametric code according to the first parametric code and the parametric code difference value when the gas supply is liquefied gas.
In embodiments of the present disclosure, the parametric code of the gas water heater is defaulted to be the first parametric code.
In specific, the gas supply dial switch 100 generally includes a first position and a second position, each of which corresponds to a dial code (1 and 2). There is a silkscreen on the gas supply dial switch 100, and the user could choose the gas supply for the gas water heater by dialing the silkscreen to a corresponding position. For instance, when the gas supply for the gas water heater is the natural gas, the gas supply dial switch 100 is dialed to the first position, and when the gas supply for the gas water heater is the liquefied gas, the gas supply dial switch 100 is dialed to the second position. The gas supply for the gas water heater is generally the natural gas, and thus the gas supply dial switch 100 of the gas water heater, when leaving the factory, may be dialed to the position corresponding to the natural gas by default.
After the gas supply for the gas water heater is determined by the determining module 20 according to the dial state information, if the gas supply for the gas water heater is the natural gas, the parametric code of the gas water heater is transformed by the parameter transforming module 30 into a parametric code (i.e., the first parametric code) corresponding to the natural gas; if the gas supply for the gas water supply is the liquefied gas, the parameter transforming module 30 acquires the parametric code difference value, and transforms the parametric code of the gas water heater into the second parametric code according the first parametric code and parametric code difference value, in which the second parametric code equals to the first parametric code minus the parametric code difference value. Therefore, the apparatus transforms the parametric code according to the first parametric code and the parametric code difference value when the gas supply for the gas water heater is changed to the liquefied gas, thereby effectively making up the errors of components among the gas water heaters and further effectively ensuring the working performance of the gas water heater.
It should be understood that the first parametric code and the parametric code difference value may be preset in the gas water heater before the gas water heater leaves the factory.
In embodiments of the present disclosure, the parametric code may include: a proportional valve maximum secondary pressure code, a maximum wind speed code, a proportional valve minimum secondary pressure code, a minimum wind speed code, a proportional valve ignition secondary pressure code and an ignition wind speed code.

Table 1

In embodiments of the present disclosure, the parameter code is a hexadecimal number, and each parameter code corresponds to a working parameter.
As shown in Table 1, the parametric code corresponding to the liquefied gas is related to the parametric code corresponding to the natural gas and the parametric code difference value. As shown in Table 1, the PH corresponding to the natural gas defaulted by the gas water heater is 99, then when the gas supply is changed to the liquefied gas, the corresponding PH is equal to 89, i.e., the corresponding PH=99-10=89. For the gas water heaters with the same model, due to the difference of the components, the first parametric code for each gas water heater may be slightly different. For example, for a gas water heater with the same model as the gas water heater shown in Table 1, if the default PH corresponding to the natural gas is 98, then when the gas supply is changed to the liquefied gas, the corresponding PH is equal to 88, i.e., the corresponding PH=98-10=88.
As can be seen from the above embodiments, when the gas supply for the gas water heater is changed from the natural gas to the liquefied gas, the parametric code needs to be transformed, and the parametric code difference value needs to be acquired for the transformation of the parametric code. In the following, how the parameter conversion module 30 acquires the parametric code difference value will be described with reference to the specific embodiments.
According to an embodiment of the present disclosure, as shown in Fig. 2, the parameter conversion module 30 acquires the parametric code difference value by the following step.
At S31, first optimal parametric codes for a plurality of gas water heaters when supplied with natural gas and second optimal parametric codes for the plurality of the gas water heaters when supplied with liquefied gas are acquired respectively. In an embodiment, the phrase "a plurality of' generally refers to 10 or more.
At S32, a difference value between the first optimal parametric code and the second optimal parametric code for each of the plurality of the gas water heaters when respectively supplied with natural gas and liquefied gas is calculated.
At S33, an average value of the difference values is calculated and the average value is taken as the parametric code difference value.
Specifically, before leaving the factory, at least 10 gas water heaters with the same model are tested. For each of the at least 10 gas water heaters, the first optimal parametric code is tested when the gas supply is the natural gas, the second optimal parametric code is tested when the gas supply is the liquefied gas, and the difference value between the first optimal parametric code and the second optimal parametric code is calculated by the parameter conversion module 30. Then, the average value of the respective difference values of the at least 10 gas water heaters is calculated by the parameter conversion module 30 and taken as the parametric code difference value. For example, an optimal PH (natural gas) of a gas water heater is A3, and an optimal PH (liquefied gas) of the gas water heater is 98, and thus a difference value therebetween is 11. In the similar way, the difference value of the PH values can be obtained for each of other gas water heaters. Then, an average value of all the difference values corresponding to the PH is calculated and taken as the parametric code difference value corresponding to the PH of the gas water heaters. Similarity, the respective parametric code difference values corresponding to other parametric codes, such as FH, PL, FL, DH or DF, may be acquired by the parameter conversion module 30. The parametric code may be transformed by the parameter conversion module 30 according to the first parametric code and the parametric code difference value when the gas supply for the gas water heater is changed from the natural gas to the liquefied gas, thereby making up the differences of components among gas water heaters.
With the parametric code transformation apparatus for a gas water heater according to embodiments of the present disclosure, the acquiring module acquires the dial state information of the gas supply dial switch, the determining module determines the gas supply for the gas water heater according to the dial state information, the parameter transformation module transforms the parametric code of the gas water heater into the first parametric code when the gas supply is the natural gas; and acquires the parametric code difference value, and transforms the parametric code of the gas water heater into the second parametric code according to the first parametric code and the parametric code difference value when the gas supply is the liquefied gas. Therefore, the parametric code is transformed by the apparatus according to the parametric code difference value when the gas supply for the gas water heater is changed, and thus the errors of components among gas water heaters can be effectively made up and the working performance of the gas water heater can further be effectively ensured.
