Description

Technical Field

[0001] This application relates to the field of washing appliance technology, and in particular to a dispensing device and a washing appliance. Background Technology

[0002] Washing appliances need to automatically dispense detergent during the washing process, so these appliances are equipped with a dispensing device. The dispensing device has a cavity that contains liquid detergent. When detergent needs to be dispensed, the detergent in the cavity is controlled to flow out and be directly or indirectly dispensed into the washing chamber. When detergent is not needed, it is necessary to prevent the detergent from flowing out of the cavity. However, during the washing process, the dispensing device may malfunction, causing the detergent in the cavity to flow out (leak) even when detergent is not needed, or even all the detergent to leak out of the washing chamber. Utility Model Content

[0003] This application aims to at least partially solve one of the technical problems in the related art. To this end, this application proposes a dispensing device.

[0004] To achieve the above objectives, this application discloses a dispensing device suitable for installation on the door of a washing appliance. The device is vertically positioned when the door is closed and horizontally positioned when it is open. The dispensing device includes a main body with a connected storage cavity and a partition cavity. The storage cavity is suitable for containing liquid detergent. When the door is open, the detergent is suitable for entering the partition cavity from the storage cavity. When the door switches from open to closed, the storage cavity and the partition cavity each retain detergent, and the detergent in the storage cavity and the detergent in the partition cavity are isolated from each other. The dispensing device is suitable for dispensing detergent from the partition cavity when the door is closed.

[0005] In some embodiments of this application, a communication port is provided between the storage cavity and the partition cavity, the communication port connecting the storage cavity and the partition cavity, so that when the door is in the open state, detergent can enter the partition cavity from the storage cavity through the communication port.

[0006] In some embodiments of this application, when the door is in the open state, the highest point of the detergent level in the storage cavity is higher than the lowest point of the connecting port and the lowest point of the partition, so that the detergent is suitable to enter the partition from the storage cavity through the connecting port.

[0007] In some embodiments of this application, when the door is in the open state, the bottom of the storage cavity is inclined from top to bottom toward the communication port and / or the partition.

[0008] In some embodiments of this application, when the door is closed, the highest point of the detergent level in the storage cavity is lower than the lowest point of the connecting port, and the highest point of the detergent level in the partition cavity is lower than the lowest point of the connecting port.

[0009] In some embodiments of this application, a partition is provided between the storage cavity and the partition cavity, the partition being adapted to isolate the detergent in the storage cavity from the detergent in the partition cavity when the door is in the closed state.

[0010] In some embodiments of this application, the partition is adapted to extend vertically when the door is in the closed state.

[0011] In some embodiments of this application, with reference to the door being in a closed state, the main body includes a front wall, a rear wall, a left side wall, a right side wall, a top wall, and a bottom wall. The partition is disposed between the front wall and the rear wall to divide the storage cavity and the partition cavity. A communication port connecting the storage cavity and the partition cavity is provided between the top of the partition and the top wall.

[0012] In some embodiments of this application, the volume of the storage cavity is greater than the volume of the partition cavity.

[0013] In some embodiments of this application, the main body is further provided with a feeding port, which is connected to the storage cavity to facilitate the replenishment of detergent into the storage cavity through the feeding port.

[0014] The second aspect of this application discloses a washing appliance, which includes the aforementioned dispensing device.

[0015] The technical solution of this application sets up a storage chamber and a partition chamber. The storage chamber is mainly used to store detergent. After each opening and closing of the door, a portion of the detergent enters the partition chamber and remains there, while the remaining detergent remains in the storage chamber. During the washing process of the washing appliance, the dispensing device dispenses detergent from the partition chamber, not the storage chamber. Even if the component controlling the detergent dispensing of the dispensing device malfunctions and causes detergent leakage from the partition chamber, only the detergent from the partition chamber will leak, and the detergent from the storage chamber will not leak, thus reducing the amount of detergent leakage.

[0016] Other advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of this application. Attached Figure Description

If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0038] The first aspect of this application discloses a dispensing device suitable for installation on the door of a washing appliance. The door has a closed state and an open state. In the closed state, the door is vertically positioned, and in the open state, it is horizontally positioned. The washing appliance has a washing chamber in which a target object can be washed. When the door is closed, the washing chamber is closed; when the door is open, the washing chamber is open. When a target object needs to be loaded into the washing chamber, the door is open and horizontally positioned. When a target object needs to be washed, the door is closed and vertically positioned. The dispensing device is installed on the inside of the door. When the door is open, detergent can be added to the dispensing device, which is temporarily stored inside. During the washing process, the detergent inside the dispensing device is controlled to be dispensed into the washing chamber. In this embodiment, the detergent is a liquid detergent. The main function of the detergent is to clean and remove dirt, or it can be used as an auxiliary agent for cleaning and removing dirt. Of course, detergents with other functions can also be used, such as rinse aids.

[0039] To prevent detergent from leaking out of the dispensing device completely when the device malfunctions, this embodiment addresses this issue.

[0040] Combination Figure 4 , Figure 7 and Figure 8As shown, in some embodiments, the dispensing device includes a main body 1000, which has a storage cavity 1100 and a partition cavity 1200 connected to each other. The storage cavity 1100 is used to store liquid detergent. When the door is in the open state, the detergent enters the partition cavity 1200 from the storage cavity 1100. It can be understood that as long as detergent enters the partition cavity 1200 when the door is in the open state, regardless of the amount of detergent entering the partition cavity 1200, it can be considered that detergent enters the partition cavity 1200 from the storage cavity 1100. When the door switches from the open state to the closed state, the storage cavity 1100 and the partition cavity 1200 respectively retain detergent, and the detergent in the storage cavity 1100 is isolated from the detergent in the partition cavity 1200. In other words, when the door is in the open state, a portion of the detergent enters the compartment 1200 from the storage chamber 1100, while the remaining detergent remains in the storage chamber 1100. When the door switches from the open state to the closed state, the aforementioned portion of the detergent remains in the compartment 1200, and the aforementioned remaining detergent remains in the storage chamber 1100. The detergent in the storage chamber 1100 is isolated from the detergent in the compartment 1200. It can be understood that the isolation of the detergent in the compartment 1200 from the detergent in the storage chamber 1100 means that in this state, the detergent in the compartment 1200 cannot enter the storage chamber 1100, and the detergent in the storage chamber 1100 cannot enter the compartment 1200.

[0041] In this embodiment, when the door is closed, the dispensing device is suitable for dispensing detergent into the diaphragm 1200. That is, when the washing machine is in the washing process and detergent needs to be added, the dispensing device controls the detergent in the diaphragm 1200 to be dispensed into the washing chamber. During the washing process, if the mechanism controlling the dispensing of detergent into the diaphragm 1200 malfunctions, the detergent in the diaphragm 1200 may leak. However, in this state, since the detergent in the diaphragm 1200 is isolated from the detergent in the storage chamber 1100, even if all the detergent in the diaphragm 1200 leaks and enters the washing chamber, the detergent in the storage chamber 1100 will not enter the diaphragm 1200 and leak. This reduces the amount of leakage when detergent leakage occurs due to a malfunction of the dispensing device.

[0042] For example, the main body 1000 is provided with an outlet 1210, which is connected to the cavity 1200. The dispensing device also includes an actuator 2000, which can block and disconnect from the outlet 1210. When the actuator 2000 blocks the outlet 1210, it can prevent the detergent in the cavity 1200 from being discharged from the outlet 1210. When the actuator 2000 disconnects from the outlet 1210, it can allow the detergent in the cavity 1200 to be discharged from the outlet 1210. That is, when detergent needs to be dispensed, the actuator 2000 is controlled to disconnect from the outlet 1210, and the detergent flows out from the outlet 1210. When the detergent dispensing is completed, the actuator 2000 is controlled to block the outlet 1210, and the detergent cannot flow out from the outlet 1210. It should be noted that the detergent needs to enter the washing cavity after flowing out from the outlet 1210. The manner in which the detergent enters the washing cavity is not limited in this article. During the washing process, if the seal between the actuator 2000 and the outlet 1210 fails, the detergent in the compartment 1200 will leak out through the outlet 1210. However, the detergent in the storage compartment 1100 will not enter the compartment 1200 and leak out through the outlet 1210, thus reducing the amount of detergent leakage when the seal between the actuator 2000 and the outlet 1210 fails. In particular, the amount of detergent stored in the compartment 1200 can be designed to be the amount required for a single wash. Even if all the detergent in the compartment 1200 leaks out during a single wash and into the washing chamber, although it is not at a suitable washing stage, the impact on the washing process can still be reduced compared to related technologies.

[0043] Combination Figure 4 and Figure 7 As shown, in some embodiments, a connecting port 1001 is provided between the storage cavity 1100 and the partition cavity 1200. The connecting port 1001 connects the storage cavity 1100 and the partition cavity 1200. When the door is in the open state, detergent can enter the partition cavity 1200 from the storage cavity 1100 through the connecting port 1001. The storage cavity 1100 and the partition cavity 1200 are connected through the connecting port 1001. When the door is in the open state, the dispensing device is also horizontally positioned. A portion of the detergent enters the partition cavity 1200 from the storage cavity 1100 through the connecting port 1001, and the remaining portion of the detergent remains in the storage cavity 1100. When the door is switched from the open state to the closed state, the dispensing device changes from horizontal to vertical positioning. The aforementioned portion of the detergent remains in the partition cavity 1200 and cannot enter the storage cavity 1100 through the connecting port 1001, and the aforementioned remaining portion of the detergent remains in the storage cavity 1100 and cannot enter the partition cavity 1200 through the connecting port 1001.

[0044] Optionally, in some embodiments, when the door is open, the highest point of the detergent level in the storage cavity 1100 is higher than the lowest point of the connecting port 1001 and the lowest point of the partition 1200, so that the detergent can enter the partition 1200 from the storage cavity 1100 through the connecting port 1001. In this state, because the detergent level in the storage cavity 1100 is higher, the detergent can pass through the connecting port 1001 and enter the partition 1200 under the action of gravity until the detergent level in the partition 1200 is the same as the detergent level in the storage cavity 1100. Detergent is present in both the partition 1200 and the storage cavity 1100. This arrangement facilitates the entry of detergent from the storage cavity 1100 through the connecting port 1001 into the partition 1200 when the door is open.

[0045] Optionally, in some embodiments, combined with Figure 4 , Figure 5 and Figure 6 As shown, when the door is open, the bottom of the storage cavity 1100 is inclined from top to bottom toward the connecting port 1001 and / or the partition 1200. The so-called bottom of the cavity is defined with the door in the open position as a reference, and the bottom of the storage cavity 1100 at this time is regarded as the bottom of the cavity (the front wall 1310 in the following text constitutes the bottom of the cavity when the door is open). The bottom of the cavity is designed to be inclined toward the connecting port 1001 and / or the partition 1200, so that the detergent in the storage cavity 1100 can more easily flow to the connecting port 1001 and then enter the partition 1200 under the guidance of the bottom of the partition 1200.

[0046] Optionally, in some embodiments, when the door is closed, the highest point of the detergent level in the storage cavity 1100 is lower than the lowest point of the connecting port 1001, and the highest point of the detergent level in the partition cavity 1200 is lower than the lowest point of the connecting port 1001. In this state, since the lowest point of the connecting port 1001 is higher than both the detergent level in the partition cavity 1200 and the detergent level in the storage cavity 1100, the detergent in the partition cavity 1200 cannot enter the storage cavity 1100 through the connecting port 1001, and the detergent in the storage cavity 1100 cannot enter the partition cavity 1200 through the connecting port 1001, thus isolating the detergent in the partition cavity 1200 from the detergent in the storage cavity 1100.

[0047] Taking a single door opening and closing process as an example, when the door is open, the detergent level in storage chamber 1100 is higher, and due to the inclined guide at the bottom of storage chamber 1100, the detergent can pass through the connecting port 1001 and enter the compartment 1200 under the influence of gravity, until the detergent level in compartment 1200 is the same as that in storage chamber 1100. Detergent is present in both compartment 1200 and storage chamber 1100. When the door switches from open to closed, the detergent in compartment 1200 falls back under gravity until its level is below the lowest point of connecting port 1001, and the detergent in storage chamber 1100 also falls back under gravity until its level is below the lowest point of connecting port 1001. At this point, detergent remains in both compartment 1200 and storage chamber 1100.

[0048] Combination Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments, a partition 1370 is provided between the storage cavity 1100 and the partition cavity 1200. The partition 1370 is adapted to isolate the detergent in the storage cavity 1100 from the detergent in the partition cavity 1200 when the door is closed. The partition 1370 facilitates the isolation of the detergent in the partition cavity 1200 from the detergent in the storage cavity 1100.

[0049] Optionally, the partition 1370 is adapted to extend vertically when the door is closed. The vertical extension of the partition 1370 facilitates the side-by-side arrangement of the compartment 1200 and the storage compartment 1100, which helps to maximize the use of space.

[0050] Combination Figures 4 to 8As shown, the orientation is with the door closed as a reference. The user stands in front of the washing appliance to control the opening and closing of the door. The main body 1000 has a front wall 1310, a rear wall 1320, a left side wall 1330, a right side wall 1340, a top wall 1350, and a bottom wall 1360. The front wall 1310, rear wall 1320, left side wall 1330, right side wall 1340, top wall 1350, and bottom wall 1360 together enclose a certain space. A partition 1370 is set between the front wall 1310 and the rear wall 1320, and the top of the partition 1370 and the top wall 1350 are alternately arranged to form a communication opening 1001. The bottom of the partition 1370 is connected to the bottom wall 1360, thus dividing the storage cavity 1100 and the partition cavity 1200. When the door is open, the partition 1200 and the storage chamber 1100 are arranged horizontally. At this time, detergent can enter the partition 1200 from the storage chamber 1100 through the connecting port 1001. When the door is closed, the partition 1200 and the storage chamber 1100 are arranged vertically. Through the isolation of the partition 1370, the detergent in the partition 1200 cannot enter the storage chamber 1100, and the detergent in the storage chamber 1100 cannot enter the partition 1200.

[0051] Combination Figure 8 As shown, in some embodiments, the volume of the storage cavity 1100 is greater than the volume of the partition cavity 1200, for example, the volume of the storage cavity 1100 is two, three, four or more times the volume of the partition cavity 1200. By such a configuration, the frequency of replenishing detergent can be reduced.

[0052] Taking a dishwasher as an example, the detergent is rinse aid. When using the dishwasher for the first time, the door is opened, dishes (the target items) are loaded into the washing chamber, and rinse aid (detergent) is injected into the storage chamber 1100. At this time, some rinse aid enters the partition chamber 1200 from the storage chamber 1100. Then the door is closed, leaving rinse aid in both the partition chamber 1200 and the storage chamber 1100. During the washing process, rinse aid from the partition chamber 1200 is added to the washing chamber. After the washing cycle, the door is opened again, the dishes (the target items) are removed, and the door is closed. During the process of opening and closing the door after the washing cycle, some rinse aid enters the partition chamber 1200 from the storage chamber 1100, leaving rinse aid in both the partition chamber 1200 and the storage chamber 1100.

[0053] When using the dishwasher for the second time, the control door opens, the dishes (target items) are loaded into the washing chamber, and then the control door closes. At this time, the partition 1200 and the storage chamber 1100 respectively retain rinse aid. During the washing process, the control chamber 1200 releases rinse aid into the washing chamber. After the washing is finished, the control door opens, the dishes (target items) are removed, and then the door is closed. During the process of opening and closing the door after the washing is finished, some rinse aid enters the partition 1200 from the storage chamber 1100, so that the partition 1200 and the storage chamber 1100 respectively retain rinse aid.

[0054] Similarly, the size of the storage cavity 1100 and the partition cavity 1200 can be designed according to the actual situation, so that it is not necessary to add rinse aid to the storage cavity 1100 every time the dishwasher is used, but only after multiple uses of the dishwasher.

[0055] Understandably, because the volume of the storage chamber 1100 is larger than that of the partition chamber 1200, under multiple uses of the dishwasher, the amount of detergent entering the partition chamber 1200 remains constant each time the dishwasher is used, until the amount of detergent in the storage chamber 1100 decreases below a certain level. This ensures a consistent detergent dispensing rate during the first few uses of the dishwasher. Understandably, the amount of detergent in the storage chamber 1100 can be monitored by a detection device to remind the user to replenish it in time. For example, the amount of detergent entering the partition chamber 1200 is consistent during the first 20 door openings and closings, but decreases during the 21st door opening and closing. This ensures a consistent detergent dispensing rate during the first 20 uses, and an alarm can be triggered on the 21st use to remind the user to replenish the detergent.

[0056] Combination Figure 1 and Figure 2 As shown, in some embodiments, the main body 1000 is also provided with a feeding port 1110, which is connected to the storage cavity 1100 to facilitate the replenishment of detergent into the storage cavity 1100 through the feeding port 1110. When detergent needs to be replenished, the door is in the open state, and the dispensing device is arranged approximately horizontally. The user can replenish detergent into the storage cavity 1100 through the feeding port 1110. After the detergent enters the storage cavity 1100, a portion of the detergent enters the partition cavity 1200. It is understood that the main body 1000 is generally provided with a cover 1120, which is used to close and open the feeding port 1110.

[0057] Combination Figure 3 , Figure 4 , Figure 9 , Figure 10 and Figure 11As shown, in some embodiments, the main body 1000 is provided with an outlet 1210 communicating with the cavity 1200. The dispensing device also includes an actuator 2000 and a drive mechanism 3000. The actuator 2000 is used to block the outlet 1210 and to disengage from the outlet 1210. The actuator 2000 is adapted to prevent the detergent in the cavity 1200 from flowing out of the outlet 1210 when blocking the outlet 1210, and to allow the detergent in the cavity 1200 to flow out of the outlet 1210 when disengaging from the outlet 1210. The drive mechanism 3000 is adapted to drive the actuator 2000 to move so that the actuator 2000 disengages from the outlet 1210.

[0058] When detergent needs to be added, the control actuator 2000 disengages from the outlet 1210, allowing the detergent to flow out. Upon completion of detergent addition, the control actuator 2000 blocks the outlet 1210, preventing further detergent flow. The detergent, after exiting the outlet 1210, must eventually enter the washing chamber. The method by which the detergent enters the washing chamber is not specified in this paper. The disengagement of the actuator 2000 from the outlet 1210 is achieved through the drive mechanism 3000, a component that outputs power. By configuring the drive mechanism 3000, automatic detergent addition during the washing process can be achieved.

[0059] Optionally, combined Figure 12 and Figure 13 As shown, in some embodiments, the drive mechanism 3000 includes an output gear 3200, the output gear 3200 is provided with a toothed portion 3210, the actuator 2000 is provided with a rack portion 2100, and the output gear 3200 is adapted to drive the actuator 2000 to move by meshing the toothed portion 3210 and the rack portion 2100 when rotating.

[0060] The drive mechanism 3000 outputs power through the output gear 3200, thereby driving the actuator 2000. The output gear 3200 outputs power in a rotating manner. For example, the drive mechanism 3000 includes a power source 3100, which can be of various types, such as a motor that converts electrical energy into mechanical energy. Specifically, the motor can be a stepper motor, a servo motor, etc. The power source 3100 directly or indirectly drives the output gear 3200 to rotate. The movement of the actuator 2000 is specifically manifested as the rotation of the output gear 3200 driving the actuator 2000 to move. When the output gear 3200 rotates, the gear tooth 3210 rotates accordingly. Through the meshing of the gear tooth 3210 with the rack part 2100, the rotation of the output gear 3200 drives the rack part 2100 to linearly displace, thereby causing the actuator 2000 to disengage from the outlet 1210.

[0061] Combination Figure 12 and Figure 13 As shown, in some embodiments, the toothed portion 3210 is adapted to separate from the rack portion 2100 after the actuator 2000 disengages from the outlet 1210. The dispensing device also includes an elastic element 4000, which is adapted to generate force on the actuator 2000 to drive the actuator 2000 toward the outlet 1210 to block the outlet 1210 after the toothed portion 3210 and the rack portion 2100 separate.

[0062] Specifically, the shifting tooth 3210 is not arranged along the entire circumference of the output gear 3200, but at a certain position on the circumference of the output gear 3200. Thus, when the output gear 3200 rotates, the shifting tooth 3210 meshes with the rack 2100 and drives the actuator 2000 to disengage from the outlet 1210. When the output gear 3200 continues to rotate at a certain angle, the shifting tooth 3210 separates from the rack 2100. In this embodiment, by setting an elastic element 4000, the elastic element 4000 generates force on the actuator 2000. When the output gear 3200 rotates and the toothed part 3210 meshes with the rack part 2100, thereby driving the actuator 2000 to disengage from the outlet 1210, the elastic element 4000 undergoes elastic deformation to accumulate elastic potential energy and generate force on the actuator 2000. When the output gear 3200 continues to rotate at a certain angle, the toothed part 3210 separates from the rack part 2100, and the elastic element 4000 releases elastic potential energy, thereby driving the actuator 2000 to move towards the outlet 1210 and block the outlet 1210. In this way, when the output gear 3200 drives the actuator 2000, the outlet 1210 can be blocked without changing the direction of movement of the output gear 3200, which is more conducive to the control of the drive mechanism 3000.

[0063] Understandably, by alternately engaging and disengaging with the rack section 2100 as the output gear 3200 rotates, multiple detergent dispensing operations can be achieved. For example, when the output gear 3200 rotates two revolutions, the gear part 3210 and the rack section 2100 sequentially undergo four steps: engagement, disengagement, engagement, and disengagement. The first step causes the actuator 2000 to disengage from the outlet 1210; the second step causes the actuator 2000 to block the outlet 1210; the third step causes the actuator 2000 to disengage from the outlet 1210; and the fourth step causes the actuator 2000 to block the outlet 1210. Thus, two rotations of the output gear 3200 complete two detergent dispensing operations. Alternatively, it can be understood that when the output gear 3200 rotates for the first time, the toothed part 3210 and the rack part 2100 first mesh and then separate to complete the first addition of detergent. When the output gear 3200 rotates for the second time, the toothed part 3210 and the rack part 2100 continue to mesh and then separate to complete the second addition of detergent, and so on.

[0064] Combination Figure 12 and Figure 13 As shown, in some embodiments, the actuator 2000 includes a flexible sealing plug 2200, which is adapted to disengage from and seal the outlet 1210 via the sealing plug 2200. Specifically, the flexible sealing plug 2200 is elastically deformable. For example, the sealing plug 2200 is made of materials such as silicone or rubber. With this configuration, when the actuator 2000 seals the outlet 1210, the sealing plug 2200 contacts the outlet 1210 and seals it. The sealing plug 2200 deforms, thereby better sealing the outlet 1210.

[0065] The second aspect of this application discloses a washing appliance, which can be a dishwasher, a washing machine, etc. Of course, the washing appliance can also be other types of products. The washing appliance includes the above-mentioned dispensing device, which is used to install on the door of the washing appliance. The door has a closed state and an open state. When the door is closed, it is vertically arranged. When the door is open, it is horizontally arranged. Vertical can be understood as roughly up and down. Horizontal and vertical are perpendicular, which can be understood as horizontal direction.

[0066] The dispensing device includes a main body 1000, which has a storage chamber 1100 and a partition chamber 1200 connected to each other. The storage chamber 1100 is used to store liquid detergent. When the door is open, the detergent enters the partition chamber 1200 from the storage chamber 1100. When the door is closed, both the storage chamber 1100 and the partition chamber 1200 retain detergent, and the detergent in the storage chamber 1100 is isolated from the detergent in the partition chamber 1200. When the door is closed, the dispensing device is suitable for dispensing detergent from the partition chamber 1200. That is, when the washing appliance is in the washing process and detergent needs to be added, the dispensing device controls the detergent in the partition chamber 1200 to be dispensed into the washing chamber. If the detergent dispensing mechanism in the control chamber 1200 malfunctions during the washing process of the washing appliance, the detergent in the control chamber 1200 may leak. However, in this state, since the detergent in the control chamber 1200 is isolated from the detergent in the storage chamber 1100, even if all the detergent in the control chamber 1200 leaks and enters the washing chamber, the detergent in the storage chamber 1100 will not enter the control chamber 1200 and leak. This reduces the amount of leakage when detergent leakage occurs due to a malfunction in the dispensing device.

[0067] It is understood that the dispensing device of the washing appliance in this embodiment adopts the technical solution of the above embodiment, and therefore has at least the beneficial effects brought about by the technical solution of the above embodiment, which will not be repeated here.

[0068] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
