Description

Self-adaptive food purifier with grouping type purifying bins

Technical Field

The present application relates to food purifiers, and more particularly, to an adaptive food purifier having a modular purification cartridge.

Background

The food purifier is equipment for carrying out pesticide residue treatment on food materials. There are three technologies currently on the market: ozone, ultrasound and electrolyzed water. The water electrolysis technique is taken as an example for explanation: the water electrolysis technology adopts an electrochemical method, and the working principle of the water electrolysis technology is that at least two metal pole plates are placed in water and are respectively connected with the positive pole and the negative pole of a direct current power supply, so that a positive potential field is formed on the peripheral side of the metal pole plate connected with the positive pole, and a negative potential field is formed on the peripheral side of the metal pole plate connected with the negative pole, and a series of electrochemical changes can be generated in the water. First, the intermolecular attractive force (hydrogen bond) of the water molecule group is broken largely, and the number of constituent molecules of the water molecule group is largely reduced to form a small molecule group, thereby improving the water activity. Secondly, because the water used in most areas of China is tap water, the current flowing process leads chloridization dissolved in the water to synthesize hydrochloric acid and hypochlorous acid, and further leads the hydrochloric acid to be converted into new hypochlorous acid, strong oxygen and strong hydrogen. Thirdly, the covalent bond of part of water molecules is broken to form oxygen, hydrogen, hydroxyl and free radical (-OH).

Through the change, most of bacterial viruses and the like in food materials soaked in water can be quickly killed (about 30 seconds) by hydrochloric acid, hypochlorous acid, oxygen, hydrogen, hydroxyl and small molecular group water formed in the water, and residual pesticides, clenbuterol, hormones and antibiotics carried by meat, vegetables and the like soaked in the water are effectively degraded into inorganic salt, so that the original taste of the food is restored by removing the pesticide residues and the bacterial viruses, and the purpose of purifying the food is achieved.

At present, the food purifier is divided into according to the use occasion: home appliances and commercial appliances. The household machine is applied to families, and the commercial machine is applied to public occasions such as kindergartens, schools, canteens of institutions and the like. The problem that continuous work easily generates heat exists in domestic machine and commercial machine in the use, has two thousandths of commercial machine to have the problem of protectiveness shutdown in the start-up process, causes user experience poor.

SUMMERY OF THE UTILITY MODEL

The inventor finds that the reason for the problem of heat generation during continuous operation of the food purifier and the problem of protective shutdown is that: the salinity of water quality in different areas of China is different. The salinity of the water is expressed by the conductivity. The conductivity range of tap water in China is less than 1000 ppm. For example: the water conductivity of the tannin is 600ppm, and the conductivity is high. Southern Guangzhou uses water as the mineral permeating water and has low conductivity. And the higher the salinity of the water is, the higher the relative conductivity is, and the smaller the resistance value is. Under the condition of a certain voltage, the lower the resistance value is, the easier the current passes through, and the larger the current is than the original current, so that a large current is formed, and the food purifier is easy to heat when continuously working and even can cause protective shutdown. In order to solve the above problem, the inventors considered to increase the power of the power supply from the power supply design, which would greatly increase the product cost. The inventor also considers designing a set of circuit to reduce the current, which increases the complexity of the circuit and also greatly increases the product cost. Finally, in order to achieve the purposes of unchanged purification effect, no increase in product cost and no increase in circuit complexity, the inventor finds that the problems can be well solved by dividing a plurality of purification electrodes into a plurality of groups, putting only part of the purification electrode groups at the time of starting up, and putting the rest groups of the purification electrode groups at intervals of a preset time. The present application was devised based on this.

wherein the controller is configured to turn on only a portion of the set of purge electrodes at power-on.

Optionally, the controller is further configured to turn on a remaining set of purge electrodes every preset time after turning on the portion of the set of purge electrodes.

Optionally, the adaptive food purifier is a household appliance, the plurality of purifying electrodes are equally divided into three groups of purifying electrode groups, and the controller is configured to turn on only one group of purifying electrode groups at the time of starting the appliance, and turn on one of the remaining purifying electrode groups at a preset time interval.

Because only part of the purification electrode group is put in when the machine is started, large current cannot be generated when the machine is started.

Detailed Description

FIG. 1 is a block schematic diagram of an adaptive food purifier having a ganged purification cartridge according to one embodiment of the present application. Fig. 2 is a schematic and diagrammatic view of the adaptive food purifier with a modular purification cartridge of fig. 1. Referring also to fig. 2, as shown in fig. 1, the present embodiment provides an adaptive food purifier 100 with grouped purifying bins, which is a polarization type purifier, and generally comprises: power supply 10, purification bin 20 and control module 30. The power supply 10 is used for supplying power to the control module 30 and the purification bin 20. The purification bin 20 is a grouped purification bin, and has a plurality of purification electrodes for placing in water containing food and purifying the food in an electrified state, and the purification electrodes are divided into a plurality of purification electrode groups 21. The control module 30 includes a controller 31 and a plurality of branch control circuits 32. The controller 31 is electrically connected to the power supply 10 and the plurality of branch control circuits 32, and is configured to generate a control signal according to a received external signal, control the plurality of branch control circuits 32 such that the plurality of branch control circuits 32 correspond to the plurality of purge electrode groups 21 one by one, and each branch control circuit 32 is configured to turn on or off the corresponding purge electrode group 21 according to the received control signal of the controller 31. Wherein the controller 31 is configured to turn on only a portion of the set of purge electrodes 21 at power-on.

Wherein, food purification machine 100 divides into according to the use occasion: home appliances and commercial appliances. The household machine is applied to families, and the commercial machine is applied to public occasions such as kindergartens, schools, canteens of institutions and the like.

The control module 30 may be implemented by a chip and a signal circuit. The control module 30 may also be implemented by signal circuitry. In this embodiment, the controller 31 may be an MCU (single chip microcomputer). The branch control circuit 32 is a circuit with an on-off. The on-off device can be a mos tube, a relay or a triode. The external signal may be an artificial input signal, for example, a signal generated when an operator presses a switch with a hand, presses both hands, or the like. The ambient signal may also be a feedback signal, e.g. generated by various sensors.

Further, in this embodiment, the controller 31 is further configured to turn on a remaining purge electrode set 21 every preset time after turning on the portion of the purge electrode sets 21.

Further, in this embodiment, the controller 31 is further configured to turn on one of the remaining purge electrode sets 21 to turn on all of the remaining purge electrode sets 21 at a predetermined time interval after turning on the portion of the purge electrode sets 21.

In particular, the adaptive food purifier 100 may be a home machine. The plurality of purge electrodes are equally divided into three groups of purge electrode groups 21. More specifically, in the present embodiment, the number of the purge electrodes of the home appliance is thirty-one, and the thirty-one purge electrodes are equally divided into three groups of purge electrode groups 21, and each of the purge electrode groups 21 is eleven. The three groups of purge electrode groups 21 are specifically a first purge electrode group, a second purge electrode group, and a third purge electrode group. Each set of purge electrode groups 21 is individually controlled by a corresponding branch control circuit 32. Of course, two sets of purge electrode sets 21 may be controlled independently, and the other set of purge electrode sets 21 may be controlled independently. If three groups of purification electrode groups 21 are connected in parallel for use, the use state before improvement is realized. In the present application, the controller 31 is configured to conduct only one or two sets of the purge electrode sets 21 at power-on, and conduct one remaining purge electrode set 21 at a predetermined time interval, that is, to implement the constant current power control at power-on. Constant current power supply control: for example, the home-machine set constant current value is 6A, and the commercial-machine set constant current value is 50A. When the salinity of the water quality is high (the conductivity is high), the current value of the household machine reaches 9A, the current value of the commercial machine may reach 70A, and the current is required to be not increased at a constant value at this time, so that the normal operation of the food purifier 100 is ensured. That is, when the power is turned on, the number of the cleaning electrode groups 21 is one or two, and the number of the groups to be turned on is small, for example, from 31 to 22, the current is reduced by one third. If the original peak current pulse is 9A, the current changes linearly, and the current pulse which is less input in one group is 6A. Such input ensures that automatic shutdown is not possible. One group with low efficiency is thrown, another group can be thrown at intervals of 5 seconds, the original 9A pulse is changed into 6A pulse, the constant current is 6A, and the constant current is increased to 7A on the basis of 6A and 6A, so that the food purifier 100 can never be stopped. The first purge electrode group 21 may be put in three times, and the second purge electrode group 21 may be put in 5 seconds after the first purge electrode group is put in, and the third purge electrode group 21 may be put in 5 seconds after the second purge electrode group is put in. Therefore, the problem of large current during starting can be solved, and the working efficiency is not reduced. Moreover, if the salinity of the used area is high, such as the tannin, two groups of purification electrode sets 21 can be directly used for working, the two groups of purification electrode sets 21 can achieve good effect, and the problem of heating can not be generated during continuous working.

In particular, referring to fig. 1, the adaptive food purifier 100 is a commercial machine. The existing commercial machine has one hundred, seventy and twelve purifying electrodes which are equally divided into four groups of purifying electrode groups 21, and each group of purifying electrode groups 21 has forty-three purifying electrode groups. The controller 31 is configured to turn on only three sets of the purge electrode sets 21 at the time of power-on, and turn on the remaining purge electrode sets 21 at a predetermined time interval. Therefore, the problem of protective shutdown possibly existing when the commercial machine is started in the prior art can be solved, and the purification efficiency of the commercial machine can be ensured.

The self-adaptive food purifier 100 with the grouped purifying bins divides a plurality of purifying electrodes into a plurality of groups of purifying electrode groups 21 which can be controlled independently, and when the self-adaptive food purifier is started, the self-adaptive food purifier is configured to be only connected with a part of the purifying electrode groups 21 and then connected with the rest of the purifying electrode groups 21 at intervals of preset time. Since only a part of the purge electrode group 21 is put in at the time of power-on, a large current is not generated at the time of power-on. And the rest of the purification electrode groups 21 are put into work together subsequently, so that the purification efficiency is ensured. Because the power of the power supply 10 is not increased, the complexity of the circuit is not greatly increased, and only the control circuit is slightly adjusted, the original product cost can be basically kept unchanged.

In this embodiment, as shown in fig. 2, the adaptive food purifier 100 with a grouped purifying bin further includes a TDS conductivity measuring module 40 electrically connected to the control module 30 for monitoring conductivity in water to generate a feedback signal and sending the feedback signal to the control module 30, and the controller 31 is further configured to receive the feedback signal and accordingly control different groups of purifying electrode groups to operate. For example, when the TDS conductivity measuring module 40 detects that the conductivity of the water is 600ppm after the household appliance is fully turned on, the controller 31 controls the first branch control circuit to be disconnected, and two sets of purification electrode sets are left to operate. At this moment, not only can work efficiency be guaranteed, but also the problem of generating heat that continuous operation brought can be avoided. When the TDS conductivity measurement module 40 detects conductivity in the water at 100ppm, for example, after the household machine is fully powered on, the controller 31 keeps the three sets of cleaning electrode sets in operation.

In this embodiment, as shown in fig. 2, the food purifier 100 is powered by the same power source. The power supply 10: two output points are provided, one is a working output and provides large current for the work of the purifying bin 20; the other is the control circuit output, which powers the control module 30.

The control part: is divided into two parts. One part is a controller 31(MCU) which mainly has the functions of signal acquisition, analysis and output; the other part is a large current output control part which is controlled by the MCU and receives signals from the MCU so as to carry out the next work. The large current control part is internally provided with one to a plurality of branch control circuits 32, and each branch circuit is identical and equivalent. Each branch circuit corresponds to a particular purge electrode set 21 in purge bin 20. Wherein a primarily functioning on-off switch (mos) in the branch control circuit 32 connects the power supply 10 with the purge electrode group 21 of the purge bin 20, denoted as mos1, mos2. The mos receives a signal from the MCU to control whether each branch control circuit 32 is turned on, i.e., whether the power supply 10 supplies power to a certain purge electrode group 21.

Working part (purification bin 20): inside the purifying chamber 20, there are TDS conductivity measuring module 40, and several purifying electrode sets 21 corresponding to each branch control circuit 32 of the large current control part.

The working principle is as follows:

when the water purifier is started to work, the purifying bin 20 is placed in a water pool, and the TDS conductivity measuring module 40 in the purifying bin 20 starts to work first to monitor the water quality. The data that will gather feeds back to controller 31MCU (singlechip), and controller 31 processing information carries out analysis and judgement, gives the mos pipe transmission signal of the on-off ware of branch control circuit 32, controls on-off ware mos and closes or breaks off, and different TDS numerical values can make the mos of different quantity close or break off. Thereby controlling the operation of different numbers of purifying electrodes in the purifying bin 20 to realize the normal operation of the food purifier 100.

The food purifier 100 can work normally in all areas, namely, the purifier can work normally under the condition of municipal tap water (the conductivity is less than 1000ppm), and a good purification effect is achieved.

FIG. 4 is a schematic flow chart diagram of a method of controlling an adaptive food purifier having grouped purification bins according to one embodiment of the present application. The embodiment also provides a control method of the self-adaptive food purifier with the grouped purifying bin, the self-adaptive food purifier is a polarized purifier, the self-adaptive food purifier comprises a purifying bin, the purifying bin is the grouped purifying bin, the purifying bin is provided with a plurality of purifying electrodes, the purifying electrodes are divided into a plurality of purifying electrode groups, and each purifying electrode group is controlled independently. The control method comprises the following steps: when the machine is started, only part of the purification electrode group is conducted.

As shown in fig. 3, the control method further includes: and after the partial purification electrode groups are conducted, conducting the other purification electrode groups at intervals of preset time.

As shown in fig. 4, the control method further includes: after the partial purification electrode groups are conducted, conducting one other purification electrode group at a preset time interval until all the other purification electrode groups are conducted.
