Description

TECHNICAL FIELD

[0001] The present application relates to instant drink machine control technology, in particular to a method for protecting a thyristor of an instant drink machine. BACKGROUND

[0002] At present, the instant drink machine (such as a boiling water bottle and an instant drink machine) of a low-cost solution adopts a relay to control an instant heating tube. Since the solution adopts a relay to adjust power, the relay is frequently actuated, which is likely to cause damage to the relay. If power adjustment is not performed, the effect of the water temperature is difficult to guarantee under different working conditions, thereby affecting the service life of the whole machine.

[0003] In other solutions, a solution also adopts a thyristor to drive a high-power heating tube, which facilitates adjustment of heating power. However, if the user continuously dispenses hot water, the thyristor is likely to be powered for a long time under a large current, which causes the temperature of the thyristor to rapidly rise. In the case of continuous dispensing of hot water, the junction temperature of the thyristor is likely to be reached, thereby causing control failure of the thyristor and affecting the service life of the whole machine. At present, there is still no effective method to reduce the temperature rise of the thyristor during continuous dispensing of hot water, and long-term continuous dispensing of water will affect the service life of the whole machine.

[0046] In the exemplary embodiments of the present application, the time length of the water boiling stage and / or the waiting stage in the hot water dispensing process can be adjusted adaptively by identifying the number of recorded continuous hot water making pots (identification operation times), so as to reduce the temperature rise of the thyristor. The adjustment schemes of the time length of the waiting stage and the time length of the water boiling stage are described in detail below.

[0056] In the exemplary embodiments of the present application, during the continuous hot water dispensing process, if normal temperature water is suddenly selected, i.e. the heating tube does not need to be controlled by the thyristor, the continuous hot water making cycle number M can be cleared. When the continuous hot water making is started again, the M is counted again.

[0057] In the exemplary embodiments of the present application, after the n-th hot water dispensing cycle is completed, the method can further comprise:

[0058] When the interval time t is greater than or equal to the first time ta and less than a preset second time tb, it is determined that the current instant drinking machine enters the continuous hot water dispensing state again after the pause, the last continuous hot water making cycle number M is kept, and the time length of the waiting stage in the n+1-th hot water dispensing cycle is adjusted according to the M and the first time ta.

[0059] In the exemplary embodiments of the present application, the second time tb can comprise:

[0065] Scheme two, adjustment scheme of the length of the boiling stage (such as Figure 3

[0066] In the exemplary embodiments of the present application, according to the selection of the water temperature grade, the target temperature Tn can be determined, the length of the waiting stage is adaptively adjusted, and the reduction of the silicon temperature rise is realized.

[0067] In the exemplary embodiments of the present application, the mediation scheme can include:

[0068] 1) In the first round of heating water, after selecting the temperature grade (target temperature T1), the length of the boiling stage Ton and the length of the waiting stage Toff are used for water making, the whole boiling making is started to be timed, the interval time t from the completion of the whole boiling making to the start of the next working stage is counted, if t meets the time range of , then the hot water is selected to continue to be made (in the case of user's need, for example, the customer selects the temperature grade of hot water), and the number of continuous hot water making M is recorded to be added by 1 (i.e. M=M+1, the initial value of M is 0), at this time M=1;

[0069] 2) In the second round of heating water, after selecting the temperature grade (target temperature T2), the length of the boiling stage can be adjusted to The length of the waiting stage can be kept as Ton, after the completion of the whole boiling making (hot water making period), the interval time t from the completion of the whole boiling making to the start of the next boiling stage is started to be timed, if t meets the time range of , then the hot water is selected to continue to be made (in the case of user's need, for example, the customer selects the temperature grade of hot water), and the number of continuous hot water making M is recorded to be added by 1, at this time M=2;

[0070] 3) In the nth round of heating water, after selecting the temperature grade (target temperature Tn), the length of the boiling stage can be adjusted to The length of the waiting stage can be kept as Ton, after the completion of the whole boiling making, the interval time t from the completion of the whole boiling making to the start of the next boiling stage is started to be timed, if t meets the time range of , then the hot water is selected to continue to be made (in the case of user's need, for example, the customer selects the temperature grade of hot water), and the number of continuous hot water making M is recorded to be added by 1, at this time M=n-1;

[0071] 4) In the (n+1)th round of heating water, after selecting the temperature grade (target temperature Tn+1), the length of the boiling stage can be adjusted to The length of the waiting stage can be kept as Toff; after the completion of the whole boiling making, the interval time t from the completion of the whole boiling making to the start of the next boiling stage is started to be timed, if t meets the time range of , then the hot water is selected to continue to be made (in the case of user's need, for example, the customer selects the temperature grade of hot water), and the number of continuous hot water making M is recorded to be added by 1, at this time M=n.​

[0072] In the exemplary embodiments of the present application, the method can further comprise: when the next water dispensing after the nth hot water dispensing cycle is non-hot water, determining that the instant drinking machine ends the continuous hot water dispensing state, and clearing the value M of the continuous hot water making cycle count bit.

[0073] In the exemplary embodiments of the present application, during the continuous hot water dispensing, if normal temperature water is suddenly selected, i.e. the heating tube does not need to be controlled by the thyristor, the continuous hot water making cycle count M can be cleared. When the continuous hot water making is started again, M is counted again.

[0074] In the exemplary embodiments of the present application, after the nth hot water dispensing cycle ends, the method can further comprise:

[0075] when the interval time t is greater than or equal to the first time ta and less than a preset third time tc, determining that the instant drinking machine enters the continuous hot water dispensing state again after the pause, retaining the value M of the last continuous hot water making cycle count bit, and adjusting the time of the water boiling stage in the (n+1)th hot water dispensing cycle according to the value Nn and the first time ta.

[0076] In the exemplary embodiments of the present application, the third time tc can comprise:

[0077] In the exemplary embodiments of the present application, after the whole water boiling making (the nth hot water dispensing cycle) is completed, the interval time t from the start of the timing to the start of the next water boiling stage, if t satisfies the time range of , the continuous making cycle count M is not increased but also cleared.

[0078] In the exemplary embodiments of the present application, after the nth hot water dispensing cycle ends, the method can further comprise:

[0079] when the interval time t is greater than or equal to the third time tc, determining that the instant drinking machine ends the continuous hot water dispensing state, and clearing the value M of the continuous hot water making cycle count bit.

[0080] In the exemplary embodiments of the present application, after the whole water boiling making (the nth hot water dispensing cycle) is completed, the interval time t from the start of the timing to the start of the next water boiling stage, if t satisfies the time range of , the continuous making cycle count M is not increased but also cleared.

[0081] In the example embodiments of the present application, by adaptively adjusting the length of the water boiling stage, the working time Ton of the water boiling stage is shortened, the length of the water boiling stage controlled by the silicon controlled rectifier is reduced, and as the water boiling time is reduced, the temperature of the silicon controlled rectifier is rapidly reduced, thereby guaranteeing the user's water experience to the greatest extent, i.e., without affecting the instant drinking effect, while guaranteeing the normal temperature rise of the silicon controlled rectifier. In addition, according to the user's use condition, the continuous production cycle number M is cleared in time, thereby further improving the user's use experience. In addition, as the continuous water is continuously discharged, the length of the water boiling stage and the length of the waiting stage are gradually balanced, i.e., the temperature of the silicon controlled rectifier is no longer continuously increased, and at the same time, the user is informed to not continuously use hot water.

[0082] In the example embodiments of the present application, by shortening the working time Ton of the water boiling stage, the temperature of the silicon controlled rectifier can be reduced, but it cannot be reduced unlimitedly, otherwise the normal water boiling operation cannot be met. In the example embodiments of the present application, by continuously adjusting the length of the water boiling stage, the temperature rise of the silicon controlled rectifier gradually reaches the temperature balance through the intermittent working mode.

[0083] In the example embodiments of the present application, a scheme of directly shortening the water boiling time Ton after recording the number of continuous hot water production is also proposed.

[0084] In the example embodiments of the present application, the method can further include:

[0085] When the number M reaches the cycle number Q, the length of the water boiling stage is directly adjusted to Ton-TQ; wherein Q is the cycle number of the previous use before the temperature rise of the silicon controlled rectifier reaches the limit value, and TQ is the preset adjustment time length capable of making the silicon controlled rectifier reach the temperature stable value.

[0086] In the example embodiments of the present application, the adjustment scheme can include:

[0087] 1) In the first cycle of producing hot water, after selecting the temperature grade (target temperature T1), the water is produced by using the water boiling stage length Ton and the waiting stage length Toff, the whole water production is completed, the interval time t from the beginning of the next water boiling stage is started to be counted, if t satisfies the time range of , then the continuous hot water production is selected (in the case that the user needs, for example, the customer selects the temperature grade of the hot water), and the continuous hot water production cycle number M is recorded to be increased by 1 (i.e., M=M+1, the initial value of M is 0), at this time, M=1;

[0088] 2) In the second cycle of producing hot water, after selecting the temperature grade (target temperature T2), the water is produced by using the water boiling stage length Ton and the waiting stage length Toff, the whole water production (hot water discharge cycle) is completed, the interval time t from the beginning of the next water boiling stage is started to be counted, if t satisfies the time range of the time range of TQ, the method selects to continue to output hot water (in the case that the user needs, for example, the user selects a temperature grade of hot water), and records the number of continuous hot water making rounds M plus 1, at this time M = 2;

[0089] 3), by analogy, in the nth round of continuous hot water making, after selecting a temperature grade (target temperature Tn), the method uses the time length Ton of the water boiling stage and the time length Toff of the waiting stage to make water, after the whole water boiling making is completed, the method starts timing the interval time length t to the start of the next water boiling stage, if t satisfies the time range of TQ, the method selects to continue to output hot water (in the case that the user needs, for example, the user selects a temperature grade of hot water), and records the number of continuous hot water making rounds M plus 1, at this time M = n-1;

[0090] 4), when M ≥ Q, the time length of the water boiling stage can be adjusted to Ton-TQ, and the time length of the waiting stage can be kept as Toff; after the whole water boiling making is completed, the method starts timing the interval time length t to the start of the next water boiling stage, if t satisfies the time range of TQ, the method selects to continue to output hot water (in the case that the user needs, for example, the user selects a temperature grade of hot water), and records the number of continuous hot water making rounds M plus 1, at this time M = n.

[0091] In the exemplary embodiments of the present application, the method can further comprise: when the next water output after the nth hot water output period ends is non-hot water, then the method determines that the instant drinking machine ends the continuous hot water output state, and clears the value M of the continuous hot water making round count bit.

[0092] In the exemplary embodiments of the present application, in the process of continuous hot water output, if normal temperature water is suddenly selected to be output, that is, the heating tube is not controlled by the silicon controlled rectifier, then the method can clear the value M of the continuous hot water making round count bit. When the continuous hot water making is started again, the method re-counts M.

[0093] In the exemplary embodiments of the present application, the method can further comprise:

[0094] When TQ < t < 2 * TQ, the method determines that the instant drinking machine enters the continuous hot water output state again after a pause, keeps the value M of the continuous hot water making round count bit, and adjusts the time length of the waiting stage and / or the time length of the water boiling stage in the nth+1 hot water output period according to the first time length ta;

[0095] When t ≥ 2 * TQ, the method determines that the instant drinking machine enters the continuous hot water output state again after a pause, and clears the value M of the continuous hot water making round count bit.

[0096] In the exemplary embodiments of the present application, the entire water boiling preparation (the nth hot water dispensing cycle) is completed, the interval time t from the start of the next water boiling stage is counted, if t satisfies the time range of TQ < t < 2*TQ, it is selected to continue dispensing hot water, and the continuous preparation round number M is recorded without increasing but also without being cleared.
