Description

[0002] Currently, there are gas water heaters with water pumps on the market, such as gas water heaters with zero cold water and circulating boost functions. When the user does not use the gas water heater for a long time, or does not start the circulating boost function of the gas water heater for a long time during use, the water pump will cause the internal bearing friction to increase due to long-term non-rotation, the dead water in the water pump will scale due to long-term static, and the starting inertia will increase. After this situation occurs, if the user uses the circulating boost function of the gas water heater, the water pump may not rotate normally, causing a stuck phenomenon, system error, and the user cannot normally use the circulating boost function, which reduces the user's experience and increases the product's maintenance rate.

[0028] The present application will be further described in the following by way of examples, but the present application is not limited to the scope of the examples.

[0029] Embodiment 1

[0030] The present embodiment provides a control method for preventing the water pump in the water heater from being stuck, referring to Figure 1 , the control method for preventing the water pump in the water heater from being stuck comprises:

[0031] S11, obtaining the continuous non-starting duration of the water pump.

[0032] S12, when the continuous non-starting duration meets the anti-stuck triggering condition, controlling the water pump to perform the anti-stuck operation.

[0033] The anti-stuck triggering condition comprises a limiting condition for the continuous non-starting duration, when the continuous non-starting duration reaches a certain degree, the anti-stuck operation is triggered, the water pump is controlled to run for a short time, the long-time non-starting state of the water pump is interrupted, the continuous non-starting duration is cleared, the friction between the internal bearings of the water pump is reduced, the internal dead water of the water pump is prevented from being scaled due to long-term and stationary, and the starting inertia of the water pump is reduced.

[0034] The anti-stuck triggering condition can also comprise a limiting condition other than the continuous non-starting duration, which can be set according to the existing control logic of the water heater.

[0035] One or more flag bits can be used to indicate whether the continuous non-starting duration meets part or all of the items in the anti-stuck triggering condition. For example, a water pump allowed starting flag bit can be used to indicate whether the limiting condition of the minimum intervention duration for the continuous non-starting duration is met, a water pump forced starting flag bit can be used to indicate whether the limiting condition of the maximum intervention duration for the continuous non-starting duration is met, and a water pump anti-stuck output flag bit can be used to indicate whether all the items in the anti-stuck triggering condition are met.

[0036] The present embodiment triggers the anti-stuck operation by whether the continuous non-starting duration of the water pump meets the anti-stuck triggering condition, controls the water pump to run for a short time through timing in the process of the user normally using the gas water heater and the process of the gas water heater being on standby (in the power-on state), reduces the friction between the internal bearings of the water pump, avoids the internal dead water of the water pump from being scaled due to long-term and stationary, reduces the starting inertia of the water pump, and thus avoids the water pump from being stuck when starting due to long-time non-rotation.

[0037] In a specific implementation, the anti-stuck triggering condition includes that the continuous non-starting duration is greater than a first duration threshold.

[0038] When the continuous non-starting duration is greater than the first duration threshold, it indicates that the water pump has not been started for a relatively long time, the friction between the bearings inside the water pump is relatively large, and the starting inertia is also relatively large, and the urgency is relatively large. In order to avoid the continuous increase of the friction between the bearings inside the water pump and the starting inertia, the water pump is forced to start at this time, the water pump is controlled to run for a short time, the long-time non-starting state of the water pump is interrupted, the continuous non-starting duration is cleared, the friction between the bearings inside the water pump is reduced, the internal dead water of the water pump is prevented from being scaled due to long-term and static placement, and the starting inertia of the water pump is reduced.

[0039] Preferably, the first duration threshold is set to 168 hours, that is, 7 days.

[0040] The first duration threshold can be set according to actual needs.

[0041] In a specific implementation, the anti-stuck triggering condition includes that the continuous non-starting duration is greater than a second duration threshold and the water heater is in a working state and the water pump is in a non-starting state.

[0042] The second duration threshold is less than the first duration threshold.

[0043] The water pump of the water heater rotates when the circulation pressurization function is used, and does not rotate when the function is not used.

[0044] Once the water pump starts to rotate in use, the friction between the bearings inside the water pump is reduced, the internal dead water of the water pump is prevented from being scaled due to long-term and static placement, and the starting inertia of the water pump is reduced. When the water pump stops rotating, the continuous non-starting duration needs to be cleared and the timing is restarted.

[0045] When the continuous non-starting duration is greater than the second duration threshold, it indicates that the water pump has not been started for a certain time, the friction between the bearings inside the water pump is relatively large, the starting inertia is also relatively large, and the urgency is relatively large. In order to avoid the continuous increase of the friction between the bearings inside the water pump and the starting inertia, the water pump is forced to start when the water pump is still in a non-starting state in combination with the current working state of the water pump, the water pump is controlled to run for a short time, the long-time non-starting state of the water pump is interrupted, the continuous non-starting duration is cleared, the friction between the bearings inside the water pump is reduced, the internal dead water of the water pump is prevented from being scaled due to long-term and static placement, and the starting inertia of the water pump is reduced.

[0046] Preferably, the second duration threshold is set to 72 hours, that is, 3 days.

[0047] The second duration threshold can be set according to actual needs.

[0048] In the implementation, the "controlling the water pump to perform the anti-stuck operation" in step S12 includes:

[0049] controlling the water pump to operate at a preset power or a preset rotating speed for a preset time length.

[0050] The preset power is a low power, the preset rotating speed is a low rotating speed, and the preset time length is preferably 5 seconds.

[0051] The preset power, the preset rotating speed, and the preset time length can be set according to actual needs.

[0052] The following is a specific example for further illustrating the control method for preventing the water pump in the water heater from being stuck, referring to Figure 2 The method includes the following steps:

[0053] (1) When the time counting of the water pump not being started is greater than a set value 1 (for example, 72 hours), the water pump allows the starting flag to be in position 1;

[0054] (2) When the time counting of the water pump not being started is greater than a set value 2 (for example, 168 hours), the water pump forces the starting flag to be in position 1, and the water pump allows the starting flag to be cleared to position 0;

[0055] (3) If the system is in a working state and the water pump is not running under the condition that the water pump allows the starting flag to be in position 1, the water pump anti-stuck output flag is in position 1;

[0056] (4) The water pump anti-stuck output flag is in position 1 under the condition that the water pump forces the starting flag to be in position 1;

[0057] (5) If the water pump anti-stuck flag is in position 1, the water pump is controlled to rotate for a fixed time (for example, 5 seconds), and the water pump anti-stuck flag is cleared to position 0 after 5 seconds.

[0058] Embodiment 2

[0059] The embodiment provides a control system for preventing the water pump in the water heater from being stuck, referring to Figure 3 The control system for preventing the water pump in the water heater from being stuck includes:

[0060] An acquisition module 1 is configured to acquire a continuous non-starting time length of the water pump.

[0061] An anti-stuck operation module 2 is configured to control the water pump to perform an anti-stuck operation when the continuous non-starting time length meets an anti-stuck triggering condition.

[0062] The anti-stuck triggering condition includes a limiting condition for the continuous non-starting time length. When the continuous non-starting time length reaches a certain degree, the anti-stuck operation is triggered, the water pump is controlled to operate for a short time, the long-time non-starting state of the water pump is interrupted, the continuous non-starting time length is cleared, the friction between the internal bearings of the water pump is reduced, the internal dead water of the water pump is prevented from being scaled due to long-term and static placement, and the starting inertia of the water pump is reduced.

[0063] The anti-stuck triggering condition can also include a limit condition other than the continuous non-starting duration, which can be set according to the existing control logic of the water heater.

[0064] Whether the continuous non-starting duration meets part or all of the items in the anti-stuck triggering condition can be indicated by one or more flag bits. For example, a water pump allowed start flag bit can be used to indicate whether the limit condition of the minimum intervention duration of the continuous non-starting duration is met, a water pump forced start flag bit can be used to indicate whether the limit condition of the maximum intervention duration of the continuous non-starting duration is met, and a water pump anti-stuck output flag bit can be used to indicate whether all items in the anti-stuck triggering condition are met.

[0065] The embodiment triggers the anti-stuck operation by whether the continuous non-starting duration of the water pump meets the anti-stuck triggering condition. In the process of normal use of the gas water heater by the user, and in the process of long standby (power-on state) of the gas water heater, the water pump is controlled to run for a short time by timing, reducing the friction between the internal bearings of the water pump, avoiding the internal dead water of the water pump from scaling due to long-term and stationary, and reducing the starting inertia of the water pump, thereby avoiding the stuck phenomenon of the water pump during starting due to long-term non-rotation.

[0066] In specific implementation, the anti-stuck triggering condition includes that the continuous non-starting duration is greater than a first duration threshold.

[0067] Wherein, when the continuous non-starting duration is greater than the first duration threshold, it means that the water pump has not been started for a relatively long time, the friction between the internal bearings of the water pump is already relatively large, the starting inertia is also relatively large, and the urgency is very large. In order to avoid the friction between the internal bearings of the water pump and the starting inertia from continuing to increase, the water pump is forced to start at this time, the water pump is controlled to run for a short time, the long-term non-starting state of the water pump is interrupted, the continuous non-starting duration is cleared, the friction between the internal bearings of the water pump is reduced, the internal dead water of the water pump is avoided from scaling due to long-term and stationary, and the starting inertia of the water pump is reduced.

[0068] Preferably, the first duration threshold is set to 168 hours, i.e. 7 days.

[0069] The first duration threshold can be set according to actual needs.

[0070] In specific implementation, the anti-stuck triggering condition includes that the continuous non-starting duration is greater than a second duration threshold and the water heater is in a working state and the water pump is in a non-starting state.

[0071] Wherein, the second duration threshold is less than the first duration threshold.

[0072] Wherein, the water heater with the water pump rotates when the circulation boosting function is used, and does not rotate when the function is not used.

[0073] Once the water pump starts rotating in the process of use, the friction between the internal bearings of the water pump is reduced, the internal dead water of the water pump is prevented from scaling due to long-term and static placement, and the starting inertia of the water pump is reduced. When the water pump stops rotating, the continuous non-starting time needs to be cleared and restarted.

[0074] When the continuous non-starting time is greater than the second time threshold, it indicates that the water pump has not started running for a certain period of time, the friction between the internal bearings of the water pump is already relatively large, the starting inertia is also relatively large, and the urgency is relatively large. In order to avoid the continuous increase of the friction between the internal bearings of the water pump and the starting inertia, combined with the current working state of the water pump, the water pump is forcibly started when the water pump is still in the non-starting state, the water pump is controlled to operate temporarily, the long-time non-starting state of the water pump is interrupted, the continuous non-starting time is cleared, the friction between the internal bearings of the water pump is reduced, the internal dead water of the water pump is prevented from scaling due to long-term and static placement, and the starting inertia of the water pump is reduced.

[0075] Preferably, the second time threshold is set to 72 hours, i.e. 3 days.

[0076] The second time threshold can be set according to actual needs.

[0077] In specific implementation, the anti-stuck operation module 2 is specifically configured to control the water pump to operate at a preset power or a preset speed for a preset time when the continuous non-starting time meets the anti-stuck triggering condition.

[0078] Preferably, the preset power is a low power, the preset speed is a low speed, and the preset time is preferably 5 seconds.

[0079] The preset power, the preset speed, and the preset time can be set according to actual needs.

[0080] The following specific example is used to further illustrate the control method for preventing the water pump in the water heater from being stuck, which is described in detail in the following. Figure 2 The method includes the following steps:

[0081] (1) When the water pump non-starting time counting is greater than a set value 1 (such as 72 hours), the water pump allows the starting flag bit to be 1;

[0082] (2) When the water pump non-starting time counting is greater than a set value 2 (such as 168 hours), the water pump forcibly starts the flag bit to be 1, and the water pump allows the starting flag bit to be cleared to 0;

[0083] (3) Under the condition that the water pump allows the starting flag bit to be 1, if the system is in a working state and the water pump is not running, the water pump anti-stuck output flag bit is 1;

[0084] (4) Under the condition that the water pump forcibly starts the flag bit to be 1, the water pump anti-stuck output flag bit is 1;

[0085] (5) If the water pump anti-stuck flag is 1, control the water pump to rotate for a fixed time (e.g. 5 seconds), and after 5 seconds, the water pump anti-stuck flag is cleared to 0.
