Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment provides a method for controlling blockage of a filter screen of a gas water heater, as shown in fig. 1, comprising the following steps:
s1, starting the gas water heater, and calculating the actual power of the gas water heater;
s2, judging whether the filter screen is blocked according to the difference between the actual power and the theoretical power, and adjusting the rotating speed of the fan according to the blocking state so as to adjust the actual power to enable the actual power to reach the theoretical power;
and obtaining the theoretical power according to a theoretical curve of the power of the gas water heater and the rotating speed of the fan.
Therefore, the actual power of the gas water heater at a certain fan rotating speed is calculated, the actual power is compared with the theoretical power, whether the filter screen is blocked or not can be judged according to the difference between the actual power and the theoretical power, the fan rotating speed is adjusted according to the blocking state, the power of the gas water heater is adjusted, the actual power reaches the theoretical power, the constant power output of the gas water heater within a certain degree of the blockage of the filter screen is ensured, and the power of the gas water heater meets the use requirements of users.
Specifically, the power of the gas water heater and the rotating speed of the fan have a certain relation, namely when the fan is at a certain rotating speed, the gas water heater can reach corresponding power, a theoretical curve is a design curve of the power of the gas water heater and the rotating speed of the fan, and the curve is stored in a control circuit of the gas water heater; namely, when the product is designed, a corresponding curve of the fan rotating speed and the water heater power exists, and the curve represents the relationship between the theoretical power and the fan rotating speed of the product, namely the corresponding relationship between the power and the fan rotating speed of the water heater when the filter screen is not blocked. The theoretical curve can be a straight line or a curve, and different gas water heaters and fans are different in theoretical curve and are determined according to actual conditions.
In actual use, however, the fan has the condition that the filter screen is blocked, and after the filter screen is blocked, the air intake is reduced at the same rotating speed, so that the actual power of the gas water heater is reduced; therefore, whether the filter screen is blocked can be judged according to the difference between the actual power and the theoretical power.
When the filter screen is blocked, the actual power of the gas water heater is reduced and is lower than the theoretical power, and the actual power cannot meet the use requirement of a user; therefore, at this time, the rotating speed of the fan needs to be adjusted according to the blockage state, so that the power of the gas water heater is adjusted, that is, the rotating speed of the fan is adjusted, the intake air is changed, so that the power of the gas water heater is changed, the actual power reaches the theoretical power, that is, after the rotating speed of the fan is adjusted, the actual power of the gas water heater at the rotating speed reaches the theoretical power corresponding to the original rotating speed of the fan, and thus, the actual power reaches the theoretical power by adjusting the rotating speed of the fan, and the use requirements of users are met.
In specific implementation, S1, starting the gas water heater, and calculating the actual power of the gas water heater may specifically be: starting the gas water heater to normally work, wherein the fan is at a certain rotating speed, and calculating the actual running power of the gas water heater in real time, namely the actual power of the gas water heater; thereby obtaining the corresponding relation between the rotating speed of the fan and the actual power of the gas water heater, and obtaining the actual curve between the power of the gas water heater and the rotating speed of the fan based on the theoretical curve according to the corresponding relation;
wherein, the actual power of the gas water heater in S1 can be detected by detecting the bath inlet water temperature T of the water heaterIntoBath water outlet temperature TGo outAnd the water flow q are calculated and obtained, and can also be obtained by other methods.
When the temperature T of the bath inlet water passes through the gas water heaterIntoBath water outlet temperature TGo outWhen the actual power is calculated according to the water flow q, a bathing inlet water temperature sensor, a bathing outlet water temperature sensor and a water flow sensor are required to be arranged on the gas water heater, and the bathing inlet water temperature T is respectively detectedIntoBath water outlet temperature TGo outAnd water flow rate q, then calculated using formula (I):
Q＝c*ρ*q(Tgo out-TInto)(I)
Q is the product load of the gas water heater, c is the specific heat capacity of water, rho is the density of the water, and Q is the water flow; and converting the calculated load of the product into the power of the product, so as to obtain the actual power of the gas water heater.
S2, judging whether the filter screen is blocked according to the difference between the actual power and the theoretical power, and adjusting the rotating speed of the fan according to the blocking state so as to adjust the actual power to enable the actual power to reach the theoretical power; the method can be specifically as follows:
when the actual power is smaller than the theoretical power, judging that the filter screen is in a blocking state, and increasing the rotating speed of the fan so that the actual power of the gas water heater reaches the theoretical power after the rotating speed of the fan is adjusted;
and when the actual power is equal to the theoretical power, judging that the filter screen is not blocked, and maintaining the rotating speed of the fan.
Namely, when the fan is at a certain rotating speed, the actual power of the gas water heater at the moment is calculated, and when the actual power is smaller than the theoretical power corresponding to the rotating speed of the fan, the actual power of the gas water heater does not meet the use requirement at the moment, namely the intake air is lower than the theoretical value at the moment, so that the blockage of the filter screen is explained; in order to enable the gas water heater to still meet the use requirements of users when the filter screen is blocked, the rotating speed of the fan needs to be increased, namely the air intake is increased, so that the actual power of the gas water heater is adjusted, the actual power of the gas water heater reaches the previous theoretical value after the rotating speed of the fan is adjusted, namely the theoretical power corresponding to the unadjusted rotating speed of the fan, and the actual power of the gas water heater meets the use requirements of the users at the moment.
When the actual power is equal to the theoretical power corresponding to the rotating speed of the fan, the actual power of the gas water heater reaches the use requirement at the moment, the filter screen is not blocked, and the current rotating speed of the fan is maintained to continue to operate.
In specific implementation, when the actual power is smaller than the theoretical power, the rotating speed of the fan is increased, and the actual power of the water heater is the theoretical power after the rotating speed of the fan is adjusted; namely, the rotating speed of the fan is increased, so that the actual power corresponding to the rotating speed of the fan after adjustment is the theoretical power corresponding to the rotating speed of the fan before adjustment, and the use requirement of a user is met by increasing the rotating speed of the fan; this process may be determined by:
according to the actual power and the rotating speed of the fan, an actual curve of the actual power and the rotating speed of the fan can be obtained based on the theoretical curve, the actual curve and the theoretical curve are placed in the same coordinate system, when the filter screen is blocked, the actual power of the product is smaller than the power corresponding to the design curve at the same rotating speed of the fan, namely the theoretical power, and at the moment, the product does not meet the actual use requirement of a user, namely the air intake of the fan does not meet the actual requirement;
in order to guarantee the use of a user under the condition of not replacing and repairing, when the actual power of the gas water heater is smaller than the theoretical power, the rotating speed of the fan is adjusted, a point with the ordinate as the theoretical power required by the user at the time is selected from an actual curve, the abscissa corresponding to the point is the actual rotating speed of the fan when the power is reached, the rotating speed of the fan is increased to the actual rotating speed, and the actual power of the gas water heater reaches the theoretical power before the rotating speed of the fan is adjusted, so that the actual demand of the user is met by a product; can compensate through adjusting the fan rotational speed when air filter screen blocks up a little through above-mentioned operation, satisfy user's user demand, wash or change when blockking up seriously.
The theoretical power can be 6-28kW, but it does not mean that the theoretical power can only be in the above range, and the above range is provided only for reference in this embodiment, and the theoretical power can be changed according to actual use needs.
In specific implementation, the actual power of the product may be larger than the theoretical power of the product, and the product needs to be debugged at this time; because fan rotational speed is bigger or bigger program when for a long time, can lead to the efficiency of product to reduce, can lead to the reduction of product life even.
For example, as shown in fig. 3, under the same fan rotation speed condition, the calculated actual product power is compared with the designed product power, i.e., the theoretical power, and when the actual power is lower than the designed power, it indicates that the filter screen is blocked; if the product is reduced to 3-26kW, then in order to ensure that the product power is maintained at 6-28kW, the compensation procedure needs to be started to raise the rotation speed of the fan from 1500-.
Therefore, the constant power output of the product is realized to a certain extent when the air filter screen is blocked by adjusting the rotating speed of the fan for compensation, and the power of the product is ensured to meet the use requirement of a user; and when the filter screen stops up not seriously, can satisfy user's use through adjusting the fan rotational speed, carry out the washing or the change of filter screen when stopping up seriously, effectively reduced the maintenance frequency of product, promoted user's use and experienced.
Meanwhile, the rotating speed of the fan is within a certain range, so that the rotating speed of the fan is prevented from exceeding the maximum range of the rotating speed of the fan in the process of increasing the rotating speed of the fan, the S2 also comprises a preset rotating speed range of the fan, and when the rotating speed of the fan is judged to reach the maximum value, the actual power of the water heater is still smaller than the theoretical power, namely the theoretical power corresponding to the rotating speed of the fan before adjustment, and an alarm for prompting a user to replace or clean the filter screen is sent out.
Specifically, the rotating speed of the fan is within a certain range, when the rotating speed of the fan reaches the maximum value, the actual operating power of a product is still lower than the design load, and then an alarm is needed at the moment to prompt a user that the air filter screen needs to be replaced or cleaned.
After the water heater is blocked and the rotating speed of the fan is adjusted, the adjusted maximum rotating speed is greater than the maximum rotating speed of the fan in the design process, so that the maximum load of the water heater can be ensured; however, in order to prevent the rotating speed of the fan from exceeding the range and influencing the use of the fan, the rotating speed of the fan is set to be within a certain range, and when the rotating speed of the fan reaches the maximum value, the actual operating power of a product is still lower than the design load, and then an alarm is required at the moment.
The range of the rotating speed of the fan can be set to 1500-6600 r/min, but the rotating speed of the fan is not represented to be only the range, the range is provided only for providing reference in the embodiment, and the rotating speed of the fan can be changed according to actual use requirements.
As shown in fig. 3, when the rotation speed of the fan is 6000r/min, the design power of the gas water heater, i.e. the theoretical power, is 28kW, at this time, the fan is at the maximum wind speed, and the water heater is at the maximum load; however, after the filter screen is blocked, the air intake of the fan at the same rotating speed is reduced, the actual power of the gas water heater is reduced to 26kW, and the use of a user cannot be met; at the moment, the rotating speed of the fan needs to be increased, namely the rotating speed of the fan is adjusted to 6600r/min, so that the actual power of the water heater is 28kW, the maximum rotating speed of the fan exceeds the maximum rotating speed of the fan in a design curve, but the rotating speed is within the range of the rotating speed of the fan, so that the rotating speed can be adjusted to maintain the maximum load of the water heater;
however, when the filter screen is seriously clogged, the rotating speed of the fan needs to be higher than 6600r/min in order to reach the maximum load of the water heater, and the rotating speed of the fan exceeds the maximum rotating speed within the limited range, which indicates that the filter screen is seriously clogged and needs to be replaced or cleaned.
In specific implementation, in order to prevent the water heater from being opened by mistake when a user does not wash or replace the filter screen when the filter screen is not blocked, the control method for blocking the filter screen of the gas water heater further comprises the step of judging whether the filter screen is washed or replaced, and equipment can be restarted only after the filter screen is cleaned or replaced.
The embodiment also provides a gas water heater which can adopt the control method of the gas water heater filter.
In specific implementation, the gas water heater comprises a bathing inlet water temperature sensor, a bathing outlet water temperature sensor and a water flow sensor, so that the bathing inlet water temperature T can be respectively detectedIntoBath water outlet temperature TGo outAnd water flow q, thereby calculating the actual power of the gas water heater;
meanwhile, the gas water heater also comprises a control assembly, wherein the control assembly is electrically connected with the fan and used for controlling the gas water heater according to the bathing water inlet temperature TIntoBath water outlet temperature TGo outAnd calculating the actual power of the gas water heater by using the water flow, comparing the actual power with the corresponding theoretical power under the same fan rotating speed, and adjusting the fan rotating speed according to the comparison relation. The function of the control assembly is not limited to the above function, and the control assembly may include other functions according to actual needs.
That is, in implementations, the control assembly of the present invention may also include other functions.
The embodiment judges whether the filter screen is blocked according to the difference between the actual power and the theoretical power by obtaining the actual power of the gas water heater, and adjusts the rotating speed of the fan according to the blocking state, thereby changing the actual power of the gas water heater, so that the actual power of the gas water heater reaches the theoretical power, the constant power output of the water heater is realized within a certain degree when the filter screen is blocked, the power of the gas water heater is ensured to meet the use requirements of users, the problem of the existing blockage of the filter screen of the gas water heater is effectively solved, the maintenance frequency of the gas water heater is reduced, and the user experience is improved.
