Example one
Referring to fig. 1 and 4, an embodiment of the present invention provides an electrostatic field structure capable of being automatically cleaned, where the electrostatic field structure 1 includes an insulating frame 10, a plurality of cathode plates 11 and a plurality of anode plates 12, the plurality of cathode plates 11 and the plurality of anode plates 12 are disposed in the insulating frame 10 at intervals, and a cathode plate 11 is disposed between two adjacent anode plates 12, each anode plate 12 and each cathode plate 11 form an electrostatic field when being powered on, so that oil drops and/or solid oil particles in oil smoke entering the electrostatic field are adsorbed on the anode plate 12, and all or part of the anode plates 12 are provided with one or more first heating portions 121 for heating the anode plates 12.
In the present embodiment, the electrostatic field structure 1 can be applied to a range hood. When the electrostatic field structure 1 is applied to a range hood, the electrostatic field structure 1 can be used as an oil fume separator of the range hood, generally in a manner of forming an electrostatic field inside the electrostatic field structure, so that when oil fume enters the electrostatic field structure 1, the anode plate 12 can adsorb substances such as small oil drops and solid oil particles in the oil fume on the surface of the electrostatic field structure, and thus, the smoke and the oil drops are separated from each other, so as to achieve the effect of purifying the oil fume.
Therefore, in order to enable the substance such as oil droplets and solid oil particles adsorbed on the anode plate 12 to be naturally dissolved and fall off the anode plate 12 to achieve the effect of automatic cleaning, and in order to enable the anode plate 12 to be sufficiently heated, it is preferable that all the anode plates 12 be provided with a plurality of first heating portions 121 for heating the anode plate 12. Specifically, the first heating part 121 may be an installation cavity for placing a heating element therein, a heating cavity for filling a heating medium therein, or a heating passage for introducing the heating medium therein.
More specifically, the first heating part 121 may be formed by providing or integrally molding a bar-shaped protrusion on the anode plate 12, and then forming the bar-shaped protrusion, that is, the first heating part 121 may be an elongated mounting cavity, a heating cavity, or a heating channel formed on the bar-shaped protrusion.
The heating element may be a heating wire or a heating tube disposed in the first heating part 121. In order to conveniently and timely replace the heating element when the heating element is out of order, the heating element is detachably disposed in the first heating part 121. The heating medium may be gas or liquid introduced into the first heating part 121. Wherein the gas may be steam and the liquid may be hot water having a certain temperature. Wherein the certain temperature can be 70-100 deg.C, such as 70 deg.C, 80 deg.C, 90 deg.C, 100 deg.C, etc.
No matter the anode plate 12 is heated by adopting a heating wire or a heating tube or the anode plate 12 is heated by introducing steam or liquid into the first heating part 121, substances polluting the environment are not generated, and the green environmental protection concept and the requirements of the manufacturing and processing industry are met.
As is well known, the cleaning method of the electrostatic field structure 1 of the conventional range hood is generally performed by removing the electrostatic field structure 1 and then directly spraying a cleaning liquid on the surface of the electrostatic field structure 1 to clean the electrostatic field structure 1. However, the above cleaning method has certain limitations, because the electrostatic field structure 1 is formed by a plurality of anode plates 12 and cathode plates 11 arranged at intervals, the distance between two adjacent plates is originally small, when cleaning liquid is sprayed, a large-range spraying method is adopted, no pertinence exists, the cleaning effect is not ideal, and the waste of the cleaning liquid is caused. In addition, because the number of plates of the electrostatic field structure 1 is large, the time consumed for cleaning is long, and the cleaning efficiency is not high.
In this patent, however, a first heating part 121 is provided on the anode plate 12 of the electrostatic field structure 1, and by using the first heating part 121 to arrange a heating element or introduce a heating medium, compared to the electrostatic field structure 1 of the conventional range hood, since the heating medium or the heating element is provided inside the first heating part 121 and the anode plate 12 is provided with the plurality of first heating parts 121, therefore, the heating of the anode plate 12 is all-round, and as can be seen from the phenomenon that substances such as oil droplets and solid oil particles are dissolved under the action of high temperature, as long as the anode plate 12 keeps a certain heating temperature, the oil droplets and solid oil particles adhered to the anode plate 12 are naturally dissolved and dropped from the anode plate 12, but are not adhered to the surface of the anode plate 12, therefore, the surface of the anode plate 12 can be kept clean, and the purpose of cleaning the anode plate 12 can be achieved without disassembling the electrostatic field structure 1.
In addition, the first heating part 121 is disposed on the anode plate 12, which is targeted to heat all the anode plates 12 and avoid waste of the heating medium.
In the present embodiment, as shown in fig. 2 and 3, the anode plate 12 is a strip-shaped plate, and in order to enable the anode plate 12 to be sufficiently heated, it is preferable that all the anode plates 12 are provided with a plurality of first heating portions 121 for heating the anode plate 12, and therefore, as an alternative embodiment, the length direction X1 of the first heating portions 121 may be set to be the same as the width direction X2 of the anode plate 12, and the plurality of first heating portions 121 may be set at intervals along the length direction Y2 of the anode plate 12. Of course, as another embodiment, the longitudinal direction X of the first heating unit 121 may be provided1And the length direction Y of the anode plate 122In the same direction, the plurality of first heating portions 121 extend in the width direction X of the anode plate 122The arrangement is spaced.
Further, as shown in fig. 1, 2, and 4, the insulating frame 10 is a rectangular frame, and the width direction X of the insulating frame 10 is3Respectively, a smoke inlet side (e.g., the left side of the insulating frame 10 in fig. 1 and 4) from which the oil smoke enters the electrostatic field and is discharged through the smoke outlet side, and a smoke outlet side (e.g., the right side of the insulating frame 10 in fig. 1 and 4), from which the oil smoke is discharged in the width direction X of the insulating frame 103And the width direction X of the anode plate 122In the same direction, i.e. the direction of the oil smoke flowing through the electrostatic field and the width direction X of the anode plate 122In the same direction, the surface of the anode plate 12 on the side close to the smoke inlet side generally has more substances such as oil droplets and solid oil particles adhered to the surface. In this regard, in order to always maintain a relatively high temperature on the surface of the anode plate 12 on the side closer to the smoke intake side, the first heating portion 121 is preferably arranged in the longitudinal direction X1And the width direction X of the insulating frame 103In the same direction, i.e., the longitudinal direction X of the first heating part 1211And the width direction X of the anode plate 122In the same direction, the plurality of first heating portions 121 extend in the longitudinal direction Y of the anode plate 122The first heating part 121 is spaced apart from the anode plate 12, so that the first heating part covers the anode plate 12 to heat the anode plate 12, thereby reducing oil droplets attached to the anode plate 12.
Furthermore, the direction of the matter such as oil drops and solid oil particles (downwards under the action of gravity) and the anode plate are12 in the width direction X2In the same direction, namely, the substances such as oil droplets and solid oil particles and the like drop from the upper side of the anode plate 12 along the lower side of the anode plate 12, and by adopting the arrangement mode, the surface of one side of the anode plate 12 close to the smoke inlet side can always keep a relatively high temperature so as to ensure that most or all the substances such as the oil droplets and the solid oil particles and the like adhered to the anode plate 12 can be dissolved and drop; but also can avoid the condition that the temperature of the lower side of the anode plate 12 is lower, so that substances such as oil drops and solid oil particles are accumulated on the lower side of the anode plate 12, and the cleaning effect of the anode plate 12 is influenced.
In the present embodiment, as shown in fig. 4, the insulating frame 10 is a rectangular frame, and includes a first fixing case 101 and a second fixing case 102 which are arranged in parallel and at an interval, and a space formed between the second fixing case 102 and the first fixing case 101 is an installation space of the anode plate 12 and the cathode plate 11, wherein the second fixing case 102 is fixed with the first fixing case 101 by a fixing rod 103. And the second stationary housing 102 and the first stationary housing 101 are each provided with a ceramic fuse tube 13. Specifically, the first stationary housing 101 includes a first stationary plate 101a and a first side plate 101b connected to the first stationary plate 101a, and the second stationary housing 102 includes a second stationary plate 102a and a second side plate 102b connected to the second stationary plate 102a, the second stationary plate 102a and the first stationary plate 101a being arranged in parallel at an interval to form an installation space for installing the anode plate 12 and the cathode plate 11. And the second side plate 102b and the first side plate 101b are both provided with ceramic fuse tubes 13, so that the electrostatic field structure 1 is powered off and stops running when electric leakage occurs, a protection effect is achieved, and meanwhile, a user is reminded that parts of the electrostatic field structure 1, such as the anode plate 12 and the cathode plate 11, need to be replaced.
Further, in order to fix the anode plates 12 and the cathode plates 11 in the insulating frame 10, the electrostatic field structure 1 further includes a cathode conductive pillar 14 and an anode conductive pillar (not shown) disposed in the insulating frame 10 in parallel and at an interval, the cathode plates 11 are disposed through the cathode conductive pillar 14, and the anode plates 12 are disposed through the anode conductive pillar.
In this embodiment, the heating medium is preferably a gas. In order to prevent heat generated by the gas introduced into the first heating part 121 from being diffused to the external environment, and prevent the anode plate 12 from being damaged due to the excessive gas introduced into the first heating part 121, which causes a safety accident, the first heating part 121 is a cavity with two open ends, and includes a first end opening 121a and a second end opening 121b opposite to the first end opening 121a, the first end opening 121a is connected to the gas supply device 2 for supplying the gas, and the second end opening 121b is provided with a control valve 3 for controlling the gas in the first heating part 121 to be discharged from the second end opening 121 b. Since the control valve 3 is provided at the second end opening 121b of the first heating part 121, it is used to control whether the gas is discharged from the second end opening 121 b. When the control valve 3 controls the gas not to be discharged through the second end opening 121b, when the gas is introduced into the first heating portion 121, the gas is not in direct contact with the external environment, so that when the anode plate 12 is heated, the heat is not diffused to the external environment quickly, the anode plate 12 can be heated quickly, and energy conservation and high efficiency are achieved. Therefore, the heat loss is less, namely, the heating of the anode plate 12 is more energy-saving and efficient by adopting the scheme of the patent.
It can be known that, when the pressure inside the first heating part 121 reaches a certain pressure value, the control valve 3 is automatically opened to discharge the gas inside the first heating part 121, so as to reduce the pressure inside the first heating part 121. Specifically, as shown in fig. 6, the electrostatic field structure 1 further includes a controller 4 and a pressure sensor 5 electrically connected to the controller 4, the pressure sensor 5 is disposed in the first heating portion 121 and is configured to sense the pressure in the first heating portion 121 and send a sensing signal to the controller 4, and the controller 4 is configured to control the opening and closing of the control valve 3 according to the sensing signal so as to adjust the pressure in the first heating portion 121. That is, when the pressure sensor 5 senses that the pressure inside the first heating part 121 is increased to a certain pressure value, a corresponding sensing signal is generated and sent to the controller 4, and the controller 4 controls the control valve 3 to be automatically opened according to the sensing signal, so as to discharge the gas inside the first heating part 121. And when pressure sensor 5 senses that the pressure inside first heating portion 121 reduces to certain pressure value, can generate corresponding inductive signal and send this inductive signal to controller 4, controller 4 at this moment just can control this control valve 3 self-closing according to this inductive signal, prevents the gaseous exhaust in first heating portion 121, prevents that the heat from spreading external environment, and is energy-conserving high-efficient.
Further, it can be known that, with the solution of the present embodiment, it is usually performed when the electrostatic field structure 1 has stopped the oil-smoke separation operation. That is, generally, since the gas is introduced into the first heating portion 121 of the anode plate 12 only when the electrostatic field structure 1 stops operating, in order to automatically introduce the gas into the first heating portion 121 of the anode plate 12 when the electrostatic field structure 1 stops operating, as shown in fig. 6, the gas supply device 2 is provided with an actuator 6 and a detector 7 electrically connected to the controller 4, the actuator 6 is configured to control the gas in the gas supply device 2 to be introduced into the first heating portion 121, the detector 7 is configured to detect an operating state of a power supply electrically connected to the anode plate 12 and the cathode plate 11, generate a detection signal, and transmit the detection signal to the controller 4, and the controller 4 is further configured to control the activation and the deactivation of the actuator 6 according to the detection signal. When the detector 7 detects that the power supply connected to the anode plate 12 and the cathode plate 11 is in a state of being changed from an operating state to a non-operating state, a detection signal is sent to the controller 4, and the controller 4 controls the starter 6 to automatically start according to the detection signal, so that the gas in the gas supply device 2 is introduced into the first heating part 121 of the anode plate 12.
Specifically, after cooking is finished for a period of time, the gas supply device 2 automatically supplies gas to the first heating portion 121 of the anode plate 12 to heat the anode plate 12, so that oil droplets and solid oil particles adhered to the anode plate 12 are dissolved. It should be noted that the gas is introduced into the first heating portion 121 of the anode plate 12 all the time in this process. When oil droplets and solid oil particles on the anode plate 12 are almost completely dissolved, gas introduction into the first heating portion 121 of the anode plate 12 may be stopped first, because the heated anode plate 12 does not immediately recover to the initial temperature due to the fact that gas introduction into the first heating portion 121 of the anode plate 12 is stopped, that is, after gas introduction into the first heating portion 121 of the anode plate 12 is stopped, the anode plate 12 may still maintain a certain temperature for a certain time, so that the oil droplets and the solid oil particles adhered to the anode plate 12 are completely dissolved and drop from the anode plate 12, so as to achieve the cleaning effect, and meanwhile, the use of gas may be saved.
In the present embodiment, in order to communicate the first heating part 121 with the air supply device 2, the electrostatic field structure 1 further includes one or more first connecting pipes 15, a first end opening 121a of each first heating part 121 is connected with a first pipe (not shown), one end of each first connecting pipe 15 is connected in series with each first pipe, and the other end of each first connecting pipe 15 is used for connecting the air supply device 2. Specifically, the first connecting pipe 15 is fixedly disposed on the insulating frame 10, and the first pipe extends from inside of the insulating frame 10 to outside of the insulating frame 10 and is connected to the first connecting pipe 15. As can be seen from the above, since the plurality of first heating portions 121 are provided at intervals in the width direction of the anode plate 12, the first channel should be provided for each first heating portion 12.
As an alternative embodiment, there is one first connecting pipe 15, and each anode plate 12 is provided with one first heating part 121 to form a row of first heating parts, so that the first heating part 121 on each anode plate 12 can be communicated with the air supply device through one first connecting pipe 15.
As another alternative embodiment, the first connecting pipe 15 is provided in plural, and each anode plate 12 is provided with a plurality of first heating portions 121. Since the anode plates 12 are spaced apart from each other, the first heating portions 121 of all the anode plates form a plurality of rows of first heating portions, wherein the arrangement direction of each row of first heating portions is the same as the longitudinal direction of the insulating frame, and each row of first heating portions corresponds to one first connecting pipeline 15, thereby achieving communication between all the first heating portions and the air supply device 2.
Since the anode plate 12 of the present invention is preferably provided with the plurality of first heating portions 121, the plurality of first connecting pipes 15 are preferably provided.
Further, since the plurality of anode plates 12 are disposed at intervals in the installation space formed between the first fixing plate 101a of the first fixing housing 101 and the second fixing plate 102a of the second fixing housing 102, that is, in the insulating frame, in order not to affect the self-operation of the electrostatic field structure 1, the first connecting pipe 15 is disposed opposite to the first end opening 121a of each row of the first heating portion, the structure is compact, and the occupied space of the first connecting pipe 15 is saved.
