Description
Technical Field
The invention relates to a control method of bubble water equipment, in particular to an ice storage control method of a bubble water module.
Background
The bubble water has fresh taste, and can play a plurality of roles of suppressing appetite, eliminating constipation, blocking absorption of sugar and fat, neutralizing acidity in the body and the like, so the bubble water is more and more favored by users.
A bubble water machine is a machine that injects carbon dioxide into water and dissolves more carbon dioxide in the water by pressurizing to produce bubble water.
The existing bubble water machine generally comprises a water tank, an evaporator, a cold water coil pipe and a circulating pump, wherein the evaporator, the cold water coil pipe and the circulating pump are arranged in the water tank, water in the water tank is used as a cooling medium and used for refrigerating drinking water in the cold water pipe, and the circulating pump is used for stirring the water in the water tank to enable the water in the water tank to circulate. And meanwhile, the internal circulating pump disturbs the flow of the secondary refrigerant in the water tank, so that the heat exchange is enhanced, and the cold water yield of the product can be effectively improved.
However, if the ice storage amount is too large or uneven, the ice stored in the cold water coil and the bubble water machine is in the same water tank, and the cold water coil is blocked; if the amount of ice storage is too small, the amount of ice storage becomes insufficient, and the cold water performance of the bubble water machine is degraded. Meanwhile, the bubble water machine generally needs to normally operate at the ambient temperature of 4-38 ℃, and the whole ice storage process is controlled by only a temperature sensor in the water tank. This results in three situations where ice storage control is required: 1. when the water tank is completely free of ice, ice storage is started; 2. starting ice storage under the condition that the water tank has a part of ice; 3. ice is stored under the working condition of low temperature environment. When the bubble water machine is in a low-temperature environment working condition, ice storage is started from a completely ice-free condition, and the problem of ice blockage of the cold water coil due to overlarge icing quantity at the front part of the evaporating coil is easy to occur because the evaporating temperature is low and the icing speed is high.
Therefore, under the working condition of low-temperature environment, how to ensure enough ice storage quantity under the three conditions at the same time and not to cause ice blockage of the cold water coil pipe has become a technical problem to be solved in the field.

Optionally, before the refrigeration mode is started, detecting whether the water level in the water tank reaches a set water level, and if the water level in the water tank does not reach the set water level, supplementing water to the water tank to enable the water level in the water tank to reach the set water level.
Further, after the water level in the water tank reaches the set water level, whether a refrigeration switch is closed or not is detected, if yes, the refrigeration mode is started, and if not, the refrigeration standby state is entered.
Specifically, a ball float valve is arranged in the water tank, and whether water is needed to be replenished to the water tank is judged by detecting the position of the ball float valve.
More specifically, if the lower float of the float valve is not closed, water needs to be replenished to the water tank, and if the lower float of the float valve is closed, the water level in the water tank reaches a set water level.
Optionally, when the refrigeration mode is started, if the liquid temperature is less than or equal to a ℃, the refrigeration standby state is entered.
Optionally, a temperature detecting member is disposed in the water tank.
Further, the temperature detecting member is a temperature sensor.
Specifically, the temperature sensor is an NTC temperature sensor.
Optionally, when the circulation pump is operated periodically according to a set program, the circulation pump is operated periodically for one period according to operation Fmin and stop Gmin.
Optionally, during the period that the circulating pump operates for n periods according to a set program, if the liquid temperature is less than c ℃, the ice storage mode is forcedly exited.
Optionally, the refrigeration system comprises a compressor, a condenser, a throttling device and an evaporator which are sequentially connected to form a circulation loop, and the evaporator is arranged in the water tank; and when the ice storage mode is exited, the circulating pump is closed after the compressor is closed for Hmin.
Through the technical scheme, the invention has the following beneficial effects:
under the condition of low ambient temperature, when ice storage is started from completely no ice, the ice storage speed is increased, the forced exit ice storage mode is set to judge the temperature c, and when the detected liquid temperature in the water tank is smaller than c ℃, the forced exit ice storage mode is carried out, so that the situation that the ice layer at the front end part of the evaporator coil is too thick and exceeds the requirement to cause that the ice of the cold water coil is blocked and water cannot be discharged can be effectively prevented. Under normal temperature operating mode, the evaporating temperature of evaporimeter is comparatively stable, when reaching certain ice storage volume, and the liquid temperature in the water tank that detects also is a comparatively stable value, through setting up to withdraw from ice storage mode judgement temperature e, when the liquid temperature in the water tank that detects is less than e ℃ when, withdraws from ice storage mode, can satisfy the ice storage demand of water tank normal temperature operating mode. Also, a condition for exiting the ice storage mode is set: after the circulating pump runs for n periods according to a set program, if the temperature of the liquid in the water tank is lower than e ℃, exiting the ice storage mode; the situation that the evaporation temperature is firstly rapidly reduced and then is increased under the condition that the water tank is completely free of ice is effectively avoided.

Referring to fig. 1 to 3, the present invention provides an ice storage control method of a bubble water module, the bubble water module includes a refrigeration system, a water tank 1, a water inlet channel and a carbonization tank 4, a refrigeration end of a refrigeration device of the refrigeration system contacts with a cooling medium in the water tank 1, a cold water coil 56 positioned in the water tank is arranged on the water inlet channel, one branch water channel of the water inlet channel is connected with the carbonization tank 4, and a circulation pump 3 is arranged on the water tank 1; the bubble water module ice storage control method comprises the following steps:
when the refrigeration mode is started, detecting the temperature of liquid in the water tank 1, and if the temperature of the liquid is higher than a ℃, starting the compressor 21 of the refrigeration system to start refrigeration and simultaneously starting the circulating pump 3;
continuously detecting the liquid temperature in the water tank 1 until the liquid temperature is lower than b ℃, entering an ice storage mode, and controlling the circulating pump 3 to run periodically according to a set program;
continuously detecting the temperature of the liquid in the water tank 1, and forcedly exiting the ice storage mode if the temperature of the liquid is less than c ℃;
if the liquid temperature is greater than or equal to c ℃, judging whether the first power-on refrigeration is performed or whether the liquid temperature is greater than d ℃ during the operation of the compressor 21 at this time; if both conditions are not met, when the liquid temperature is less than e ℃, exiting the ice storage mode; if one of the two conditions is met, after the circulating pump 3 runs for n periods according to a set program, if the liquid temperature is less than e ℃, exiting the ice storage mode;
wherein a is the refrigeration starting judging temperature of the refrigeration system, b is the ice storage mode judging temperature of the refrigeration system, c is the forced ice storage mode judging temperature, d is the total consumption judging temperature of the stored ice in the water tank, e is the ice storage mode judging temperature, and c is smaller than e.
The existing bubble water machine stores cold energy in an ice cold storage mode, meanwhile, a built-in circulating water pump disturbs the flow of the refrigerating medium in the water tank, heat exchange between the refrigerating medium and the evaporator is enhanced, ice stored by the cold water coil pipe and the bubble water machine is in the same water tank, and if the ice storage amount is too large or uneven, ice blockage of the cold water coil pipe can be caused; if the ice storage amount is too small, the ice storage amount is insufficient and the cold water performance of the whole machine is reduced. Ice storage control is required to face three conditions: 1. when the water tank is completely free of ice, ice storage is started; 2. starting ice storage under the condition that the water tank has a part of ice; 3. ice is stored under the working condition of low ambient temperature. In particular, when ice is stored at a low ambient temperature (typically, the ambient temperature is 10 ℃ or lower), ice blocking of the cold water coil 56 is likely to occur due to the low evaporation temperature and the high ice formation rate, which is caused by the large amount of ice formation at the front of the evaporator coil.
Through careful study on technical problems in the prior art, the ice storage control method of the bubble water machine is specifically designed, the forced-exit ice storage mode is set to judge the temperature c, ice storage is started from a completely ice-free condition in low ambient temperature, and the ice storage mode is forced to exit as long as the detected liquid temperature in the water tank 1 is less than c ℃, so that the ice storage amount under the working condition of low ambient temperature can be reduced, the protection of the cold water coil 56 is further realized, and the ice blockage problem of the cold water coil 56 is prevented. Meanwhile, the judging temperature e and c of exiting the ice storage mode are smaller than e, the evaporation temperature of the evaporator is stable under the normal temperature working condition (generally, the ambient temperature is about 25 ℃, for example, 15 ℃ to 35 ℃), and the liquid temperature in the detected water tank 1 is in a stable value when a certain ice storage amount is reached, so that the ice storage requirement of the normal temperature working condition can be met by exiting the ice storage mode when the liquid temperature in the detected water tank 1 is smaller than e ℃. When the water tank starts to store ice completely without ice, the circulating pump 3 needs to operate for n periods according to a set program, then judges whether the detected liquid temperature in the water tank 1 is lower than e ℃, if yes, the ice storage mode is exited, and the control setting can prevent the situation that the evaporation temperature is firstly rapidly reduced and then increased under the situation, so that the ice storage quantity is not satisfied and the ice storage requirement is effectively realized. Therefore, through the design of the bubble water module ice storage control step, three parameters are correspondingly set for three ice storage control conditions, ice storage requirements of ice storage control under three conditions can be completely met, a new ring temperature sensor is not needed to be added as a judgment basis, and cost is saved.
In general, a control system is used to coordinate and command each element of the bubble water module to implement a corresponding function, in the technical field of control of the bubble water machine, the control system belongs to a conventional technology for control, for example, in the control system, a PLC (programmable logic controller), a singlechip and the like are used as controllers, and on the basis of knowing the technical concept of the present invention, it is possible for those skilled in the art to implement control operation of the bubble water module in combination with the control system, so that the control system is not described again.
In a specific embodiment, the mode of turning off the circulation pump 3 after turning off the compressor 21 Hmin may be adopted to implement exiting the ice storage mode.
In a specific embodiment, the refrigerating device of the refrigerating system is not limited to the evaporator 23, but a conventional semiconductor refrigerating sheet may be used, and the refrigerating end of the semiconductor refrigerating sheet absorbs heat in the water tank 1 to perform refrigeration and ice storage.
In a specific embodiment, the circulation pump 3 may be set to perform periodic operation according to the operation Fmin and the stop Gmin as one period, for example, F is preferably 2, g is preferably 4, and during the period that the circulation pump 3 operates for n periods according to the set program, the circulation pump 3 is set to perform periodic operation according to the mode of operating for 2min and stopping for 4 min; or F is 3, G is 3, and the circulating pump 3 is set to periodically run according to the modes of running for 3min and stopping for 3 min; f and G can be valued according to the actual use condition.
When the water tank 1 starts to store ice under the condition of no ice, the evaporation temperature is likely to be reduced rapidly and then increased, so that the ice storage amount is not satisfied and the ice storage mode is conveniently exited. The value of n is preferably 6 according to the actual use condition, or may be other suitable values, such as 5, 7, 8, etc., and under the normal temperature working condition, after the circulating pump 3 operates for n periods according to the set program, the expected ice storage requirement can be basically realized, and at this time, if the temperature of the liquid in the water tank 1 is less than e ℃, the ice storage mode can be exited, and the ice blockage problem of the cold water coil 56 does not occur.
In order to cope with the low ambient temperature, when the detected temperature c of the liquid in the water tank 1 is no matter whether the operation of the circulation pump 3 is completed for n periods or not, the ice storage mode is directly forced to be exited, and the compressor 21 is turned off, so that the problem of ice blockage of the cold water coil 56 is effectively prevented.
Referring to fig. 3, when the bubble water machine is turned on, the bubble water machine needs to be powered on, and the powering-on refers to powering on a circuit of the bubble water machine. Then, the water level in the water tank 1 is detected, it is determined whether the water level in the water tank 1 reaches the set water level, and if the water level in the water tank 1 does not reach the set water level, the water tank 1 is replenished with water so that the water level in the water tank 1 reaches the set water level.
Specifically, in the example of fig. 2, the float valve 11 is used to determine whether the water level in the water tank 1 reaches the set water level, if the float valve 11 is not closed, the first solenoid valve 53 and the second solenoid valve 55 are opened, tap water is filtered by the filter 52, the water tank 1 is replenished, if the float valve 11 is closed, the water level in the water tank 1 is regarded as reaching the set water level, and when the water level in the water tank 1 reaches the set water level, the second solenoid valve 55 is closed.
As a specific embodiment, a liquid level sensor may be used to detect the water level in the water tank 1, for example, two liquid level probes are disposed in the up-down direction of the water tank 1, to detect the upper limit and the lower limit of the water level of the water tank 1 respectively, when the water level in the water tank 1 falls to the lower limit of the water level, to supplement water to the water tank 1 in time, to prevent the evaporator 23 and the cold water coil 56 from being exposed on the water surface, to affect the refrigerating effect, and when the water level in the water tank 1 rises to the upper limit of the water level, to alarm in time, to stop water inflow, and to prevent water from overflowing the water tank 1 due to too high water level.
Further, the water inlet time can be set, and when the water inlet exceeds the set water inlet time, the water inlet is stopped, so that the situation that the liquid level detection piece breaks down and the detection result is inaccurate is avoided.
As a specific embodiment, a water pump may be used instead of the first electromagnetic valve 53 and the second electromagnetic valve 55, when the water pump is started, tap water is filtered by the filter 52 to replenish water to the water tank 1, if the float below the float valve 11 is closed, the water level in the water tank 1 is regarded as reaching the set water level, and when the water level in the water tank 1 reaches the set water level, the water pump is turned off to stop replenishing water. The accurate water inlet time can be obtained by calculating the working time of the water pump, and the water inlet time can be used as the set water inlet time to prevent erroneous judgment.
In particular embodiments, whether the cooling mode is enabled may be determined by determining whether the cooling switch is closed. Specifically, when the cooling switch is detected not to be closed, the cooling standby state is entered until the cooling switch is detected to be closed, and when the cooling switch is detected to be closed, the control system controls the compressor 21 to be started, and the cooling operation is started. For example, a circuit switch, such as a rocker switch, a push button switch, a rotary switch, etc., is arranged in the control circuit of the compressor 21, and when the rocker switch is closed, the control system receives an electric signal generated by closing the rocker switch, so as to control the compressor 21 to start and start refrigeration operation; when the control system receives no electric signal generated by closing the rocker switch, the compressor 21 is controlled to be closed, and the refrigerating standby state is entered. Or, the control system may be a touch panel disposed on the bubble water machine, and a refrigeration button is disposed on the touch panel as a refrigeration switch, when the control system receives an electrical signal corresponding to the refrigeration start sent by the touch panel, the refrigeration switch is regarded as being closed, the compressor 21 is controlled to start, and the refrigeration operation is started, and when the control system receives an electrical signal corresponding to the refrigeration start sent by the touch panel or an electrical signal corresponding to the refrigeration stop sent by the touch panel, the refrigeration switch is regarded as not being closed, and the control system enters a refrigeration standby state.

Referring to the front-back data comparison table of the ice storage control method using the bubble water module, wherein the normal temperature working condition is exemplified by 25 ℃, the comparison is carried out, the low environment temperature working condition is exemplified by 4 ℃, and in actual use, three conditions are faced for ice storage control: 1. when the water tank is completely free of ice, ice storage is started; 2. starting ice storage under the condition that the water tank has a part of ice; 3. ice is stored under the working condition of low ambient temperature. Three parameters are set, and are detected by an NTC temperature sensor, and parameters required by three conditions of ice storage control can be obtained by combining the characteristics of a refrigerating system and reading the NTC in multiple dimensions.
Firstly, during normal temperature working conditions, the evaporating temperature of the evaporator 23 is stable, when a certain ice storage amount is reached, the temperature detected by the NTC is also a stable value, so that the ice storage requirement of the normal temperature working conditions can be met by setting the ice storage mode exit judging temperature e ℃ and exiting the ice storage mode after the liquid temperature in the water tank 1 is smaller than e ℃.
Secondly, when the water tank 1 starts to store ice under the condition of no ice, the evaporation temperature is likely to be reduced rapidly and then increased, so that the ice storage amount is not satisfied and the ice storage mode is conveniently exited, therefore, under the condition, after the circulating pump 3 is set to operate for n periods according to a set program, if the liquid temperature in the water tank 1 is less than e ℃, the ice storage mode is exited, the situation can be avoided, and the ice storage requirement is realized.
Finally, the evaporating temperature under the working condition of low ambient temperature is far lower than that under the working condition of normal temperature, the ice storage speed is increased, and at the moment, when the water tank 1 is completely free of ice, the circulating pump 3 runs for n periods according to a set program, the front end part of the evaporator coil is possibly too thick to exceed the requirement, and the cold water coil 56 is possibly blocked by ice to be discharged. In consideration of the situation, if the temperature c (c < e) is determined by setting the forced-exit ice storage mode, and if the NTC temperature of the liquid in the water tank 1 is less than c ℃, the circulating pump 3 is closed after the compressor is directly closed for 1min no matter whether the operation of the circulating pump 3 is completed or not, the ice storage amount under the low-environment temperature working condition can be reduced by forcibly exiting the ice storage mode, the protection of the cold water coil 56 during ice storage under the low-environment temperature working condition is further realized, the ice blockage of the cold water coil 56 is prevented, and the reliability of ice storage under the low-environment temperature working condition is ensured.
Three parameters under different conditions are respectively set in combination with the characteristics of the refrigerating system, three conditions are needed to face ice storage control, the NTC is adopted to detect the liquid temperature in the water tank 1, and multidimensional interpretation is carried out so as to obtain comparison data of ice storage requirements corresponding to the three conditions of ice storage control, so that the ice storage requirements of the ice storage control under the three conditions can be completely solved, a new ring temperature sensor is not needed to be added as a judgment basis, and the cost is saved.
