[0002] Ultra-long wave electric fields are now widely used in various equipment for processing food. For example, ultra-long wave electric fields are added to low-temperature quick-freezers.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] To further describe the solution of the present application, in one example of the present application, Figure 1 As shown, the circuit comprises:

[0033] Ultra-long wave unit, used to generate high voltage electric field;

[0034] Motor M3, used for controlling the ultra-long wave unit to release residual electricity;

[0035] A relay, used to control the power on and off of the ultra-long wave unit and the forward and reverse rotation of the motor;

[0036] A door switch unit, used to control the conduction of the relay coil;

[0037] Among them, the first end of the door switch unit is connected to the live wire L, the second end of the door switch is connected to the first end of the relay coil KB, the second end of the relay coil KB is connected to the neutral line N, the first end of the ultra-long wave unit is connected to the neutral line N, the second end of the ultra-long wave unit is connected to the second end of the relay first switch KA1, the first end of the relay first switch KA1 is connected to the controller output terminal Y8, the third end of the relay first switch KA1 is disconnected, the first end of the relay second switch KA2 is connected to the controller output terminal Y8, the second end of the relay second switch KA2 is connected to the first end of the motor M3, the third end of the relay second switch KA2 is connected to the second end of the motor M3, and the third end of the motor M3 is connected to the neutral line L.

[0038] In an embodiment of the present application, when the door switch unit is closed (i.e., the live wire is connected to the relay coil), power is supplied to both ends of the relay coil KB, and the first switch KA1 and the second switch KA2 of the adsorption relay are connected from the first and second ends to the first and third ends, thereby powering off the ultra-long wave unit, and at the same time, the single machine M3 changes from forward transmission to reverse transmission, thereby driving the ultra-long wave unit to connect to the bottom line PE to release residual power. When the door switch unit is disconnected (i.e., the live wire is disconnected from the relay coil), power is not supplied to both ends of the relay coil KB, and the first switch KA1 and the second switch KA2 of the relay are connected to the first and second ends, thereby powering on the ultra-long wave unit, and at the same time, the single machine M3 changes from reverse transmission to forward transmission, thereby driving the ultra-long wave unit to disconnect from the ground wire PE, and the ultra-long wave unit works normally.

[0039] It should be noted that the relay includes two parts, a relay coil and a relay switch. In the embodiment of the present application, one relay coil is used to control two relay switches at the same time. When the ultra-long wave unit works normally, the controller controls the operation of the ultra-long wave unit through the output terminal Y8, and the on or off of the door switch unit is a forced control of the ultra-long wave unit in an emergency. At this time, since the controller output terminal Y8 is disconnected from the ultra-long wave unit, the controller can no longer control the ultra-long wave unit. At the same time, when the device door is opened, the door switch unit is turned on. At this time, the ultra-long wave unit is disconnected from the controller output terminal and connected to the ground wire PE to release electricity to prevent users from electric shock. When the device door is closed, the door switch unit is disconnected and the ultra-long wave unit works normally.

[0040] In order to release the residual power in time, in some embodiments, Figure 1 As shown, the ultra-long wave unit includes an ultra-long wave power supply V1 and an ultra-long wave release electrode E3, wherein:

[0041] The first end of the ultra-long wave power supply V1 is the first end of the ultra-long wave unit, the second end of the ultra-long wave power supply V2 is connected to the first end of the ultra-long wave release electrode E3, the third end of the ultra-long wave power supply V1 is connected to the second end of the ultra-long wave release electrode E3, and the fourth end of the ultra-long wave power supply V1 is the fourth end of the ultra-long wave unit.

[0042] In the embodiment of the present application, the ultra-long wave power supply V2 is used to receive an external power supply to supply power to the ultra-long wave unit, and the ultra-long wave release electrode E3 is used to release the residual power of the ultra-long wave unit by connecting to the ground wire.

[0043] In order to stop the single machine rotation in time, in some embodiments, such as Figure 1 As shown, the circuit further includes a first limit switch S1 and a second limit switch S2, wherein:

[0044] The first end of the first limit switch S1 is connected to the third end of the relay second switch KA2, the second end of the first limit switch S1 is connected to the second end of the motor M3, the first end of the second limit switch S2 is connected to the second end of the relay second switch KA2, and the second end of the second limit switch S2 is connected to the first end of the motor M3.

[0045] In this embodiment, the circuit sets the first limit switch S1 and the second limit switch S2 between the motor M3 and the second switch KA2 of the relay. When the motor is forwarded to the second limit switch S2, the second limit switch S2 is disconnected, and the power supply of the motor M3 is disconnected and stops rotating. This can save energy and increase the service life of the motor. Similarly, when the motor is reversed to the first limit switch S1, the first limit switch S1 is disconnected, and the power supply of the motor M3 is disconnected and stops rotating.

[0046] It should be noted that the above preferred embodiment is only a specific implementation scheme proposed in this application. Those skilled in the art can select other connection positions of the limit switch as needed, which all belong to the protection scope of this application.

[0047] To further prevent the user from being electrostatically actuated, in some embodiments, the door switch unit includes one or more door actuation switches connected in parallel.

[0048] In this embodiment, the door switch unit includes one or more parallel door switches. When the door switch unit includes multiple parallel door switches, as long as one door switch is closed, the relay coil will be energized and the ultra-long wave unit will stop working; only when all door switches are disconnected (that is, no device door is opened) will the ultra-long wave unit work normally. Figure 1 As shown, the door switch unit includes two door switches connected in parallel.

[0049] In order to quickly release the residual power, in some embodiments, such as Figure 2 As shown, the circuit further includes a connecting mechanism L1, which is used to connect the rotor of the motor M3 and the ultra-long wave release pole E3.

[0050] In this embodiment, the ultra-long wave release pole E3 is connected to the rotor of the motor M3 through the connecting mechanism L1. When the motor M3 rotates, the ultra-long wave release pole E3 can be quickly driven to rotate, thereby realizing the connection or disconnection of the ultra-long wave release pole E3 with the ground wire.

[0051] It should be noted that the above preferred embodiment is only a specific implementation scheme proposed in this application. Those skilled in the art can choose other connection methods between the ultra-long wave release pole and the motor rotor as needed, all of which belong to the protection scope of this application.

[0052] In order to accurately stop the motor from rotating, in some embodiments, as Figure 2 As shown, the length of the connection mechanism L1 is greater than or equal to a first distance between the first limit switch S1 and the rotor, and the length of the connection mechanism L1 is greater than or equal to a second distance between the second limit switch S2 and the rotor.

[0053] In this embodiment, when the motor is in the positive direction and reaches the second limit switch S2, the connecting mechanism L1 contacts the second limit switch, the second limit switch S2 is disconnected, and the motor is powered off and stops. Similarly, when the motor is in the negative direction, the first limit switch S1 is disconnected, and the motor is powered off and stops. Therefore, in order to enable the first and second limit switches to contact the connecting mechanism L1, the distance from the first and second limit switches to the motor rotor needs to be less than or equal to the length of the connecting mechanism.

[0054] In order to configure the space reasonably, in some embodiments, the first distance is equal to the second distance.

[0055] In this embodiment, preferably, the distances between the first and second limit switches and the motor rotor are generally controlled, and the forces when the first and second limit switches contact the connecting mechanism can be controlled by adjusting the first and second distances, thereby disconnecting the switches in time.

[0056] In order to ensure that the motor stops rotating while the residual electricity is released, in some embodiments, the rotor, the first limit switch and the ground contact end are in the same horizontal plane.

[0057] In this embodiment, the motor rotor, the second limit switch and the ground contact end are in the same horizontal plane, which can ensure that the connecting mechanism contacts the second limit switch when the ultra-long wave release electrode contacts the ground contact end.

[0058] It should be noted that the scheme of the above preferred embodiment is only a specific implementation scheme proposed in the present application, and the connecting mechanism is generally straight by default. Those skilled in the art can also set other structures to ensure that the connecting mechanism contacts the second limit switch while the ultra-long wave release electrode contacts the ground contact end. For example, the connecting mechanism is set to a curved shape, and then the positions of the second limit switch and the ground contact end are set accordingly. These all belong to the protection scope of the present application.

[0059] The invention discloses an ultra-long wave discharge circuit, which comprises an ultra-long wave unit for generating a high-voltage electric field; a motor for controlling the ultra-long wave unit to release residual electricity; a relay for controlling the power supply disconnection of the ultra-long wave unit and the forward and reverse rotation of the motor; and a door switch unit for controlling the conduction of a relay coil; wherein the first end of the door switch unit is connected to a live wire, the second end of the door switch is connected to the first end of the relay coil, the second end of the relay coil is connected to a neutral wire, the first end of the ultra-long wave unit is connected to the neutral wire, the second end of the ultra-long wave unit is connected to the second end of a first switch of the relay, the first end of the first switch of the relay is connected to an output end of a controller, the third end of the first switch of the relay is disconnected, the first end of the second switch of the relay is connected to the output end of the controller, the second end of the second switch of the relay is connected to the first end of the motor, the third end of the second switch of the relay is connected to the second end of the motor, and the third end of the motor is connected to the neutral wire, thereby timely and efficiently releasing the ultra-long wave electricity, reducing the potential safety hazard of electric shock to users, and the invention has a simple circuit structure and strong practicality, and effectively avoids electric shock to users while saving costs.

[0060] Correspondingly, an embodiment of the present invention further provides an ultra-long wave discharge device, which includes the ultra-long wave discharge circuit as described above.

[0061] In order to further illustrate the technical concept of the present invention, the present invention also proposes an ultra-long wave discharge method, which is applied to the above-mentioned device, such as Figure 3 As shown, the specific steps of the method are as follows:

[0062] S301, when any device door is opened, the ultra-long wave unit stops working, and the motor drives the ultra-long wave unit to connect to the ground wire.

[0063] In this step, when any device door is opened, the ultra-long wave unit is powered off and stops working, and the motor drives the ultra-long wave unit to connect to the ground wire, thereby releasing residual electricity, so as to ensure that the user will not be electrocuted when opening the device door to access things.

[0064] S302, when all the device doors are closed, the ultra-long wave unit works normally, and the motor drives the ultra-long wave unit to disconnect from the ground wire.

[0065] In this step, when all the equipment doors are closed, the equipment is closed, the ultra-long wave unit is powered on and works normally, and the motor drives the ultra-long wave unit to disconnect from the ground wire.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
