Description

Technical Field

[0001] This invention relates to the field of home appliance technology, specifically to a clothing processing device and its control method. Background Technology

[0002] Clothes accumulate various stains during wear, such as dust, sweat, and oil. Traditional washing and rinsing methods rely primarily on water pressure and the chemical action of detergents. However, detergents often don't distribute evenly across the garment, making it difficult to completely remove many stains. This results in clothes looking less clean and affecting their appearance. Furthermore, bacteria, viruses, and other microorganisms on clothes may not be completely eliminated by regular washing methods, potentially leaving residues on the clothing.

[0003] Therefore, how to ensure that detergent comes into full contact with clothes and improve the washing efficiency is a problem that needs to be solved. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a clothing treatment device and its control method. By installing a micro-nano bubble generator on the outer drum, the problem of stains in clothing not being removed effectively and the problem of detergent not being able to fully contact the clothing are solved. The washing ratio is improved by bubble washing and spraying detergent.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] A garment processing device, the garment processing device comprising an inner drum, an outer drum, a bubble generating device, and a flow guiding structure;

[0007] The flow guiding structure is disposed on the outer side of the inner cylinder peripheral wall and protrudes towards the outer cylinder;

[0008] The bubble generator includes a bubble outlet, which is disposed between the inner cylinder and the outer cylinder.

[0009] Furthermore, the flow guiding structure extends along the axial direction of the inner cylinder;

[0010] The inner cylinder includes water-permeable holes, and the flow guiding structure is disposed between at least two of the water-permeable holes.

[0011] Furthermore, the bubble generating device is equipped with a light sensor at the bubble outlet end to sense the light beam from the water-permeable hole.

[0012] Furthermore, the bubble generating device is mounted on the outer cylinder, and the bubble outlet protrudes from the outside of the outer cylinder to the inside of the outer cylinder.

[0013] Furthermore, the bubble generating device includes a water inlet and an air inlet, the water inlet being connected to the circulating water pipeline of the clothing treatment equipment.

[0014] The bubble generating device also includes a mixing chamber, the interior of which is equipped with a spiral stirring structure for mixing and shearing the water flowing in from the water inlet and the gas drawn in from the air inlet to form micro-nano bubbles.

[0015] Furthermore, the garment treatment device is equipped with a spraying structure at the cylinder opening for spraying garment treatment agent into the inner cylinder.

[0016] A control method for the aforementioned garment processing equipment includes running a bubble wash program, controlling the bubble generating device to deliver bubbles into the drum, and increasing the bubble quantity parameter of the bubble wash program in response to a sensing signal triggered by a light sensor.

[0017] Furthermore, the bubble wash program includes a process of spraying a laundry treatment agent.

[0018] During the process of the bubble generating device delivering bubbles to the inner cylinder, the spraying structure is controlled to spray the clothing treatment agent into the inner cylinder.

[0019] Furthermore, after the bubble washing program is completed, a rinsing program is run.

[0020] The rinsing process includes a rinsing process and a bubble washing process, and the rinsing process and the bubble washing process are controlled to run alternately.

[0021] The bubble washing process includes controlling the bubble generating device to deliver bubbles into the cylinder;

[0022] Furthermore, during the operation of the rinsing program, in response to the sensing signal triggered by the light sensor, the bubble quantity parameter of the bubble washing program is increased.

[0023] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0024] 1. When the inner drum rotates, it causes the clothes to rub against the inner drum and also beats the clothes, simulating the friction and tumbling of clothes in water when hand washing.

[0025] 2. The inner cylinder has small holes at the location of the micro-nano bubble generator. At the same time, the bubble outlet end of the micro-nano bubble generator is equipped with a photoelectric sensor. Whenever the inner cylinder slowly rotates to the photoelectric sensor at the small holes, a pulse signal is generated. The micro-nano bubble generator increases the bubble flow rate and expands into the inner cylinder at high speed, thereby improving the diffusion of micro-nano bubbles.

[0026] 3. After the washing cycle, the rubbing stage generates a large amount of foam. The micro-nano bubbles allow the detergent foam to clean the clothing fibers more deeply. Combined with the spray above, the clothes are constantly enveloped in detergent foam, leaving no stains untouched. At the same time, the inner drum rotates at low speed, continuously tumbling the clothes in the detergent foam, simulating hand washing, providing an efficient and environmentally friendly way to clean clothes.

[0027] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Clothes accumulate various stains during wear, such as dust, sweat, and oil. Traditional washing, rinsing, and drying methods rely primarily on water pressure and the chemical action of detergents. However, detergents often fail to distribute evenly across the garment, making it difficult to completely remove many stains and leaving clothes looking unclean and affecting their appearance. Furthermore, bacteria, viruses, and other microorganisms on clothes cannot be completely eliminated by conventional washing methods alone.

[0041] This invention provides a clothing treatment device in which a micro-nano bubble generator is installed below the outer drum, solving the problem of ensuring sufficient contact between detergent and clothing. Combined with the spray technology above, this ensures even more thorough contact between detergent and clothing. The presence of micro-nano bubbles also enhances the impact force of the water flow, further improving the washing effect. Furthermore, the bursting of micro-nano bubbles generates energy, which helps remove stains and bacteria from clothing, providing double protection for cleanliness and hygiene. Simultaneously, the inner drum of the washing machine continuously rotates, causing the clothes to tumble and move. In this all-around environment, the clothes are as if they are in a simulated hand-washing environment. Stains are gradually peeled off and dissolved, greatly improving the washing efficiency and bringing users the most ideal and satisfactory washing results.

[0042] The micro-nano bubble generator is not only effective in the scrubbing and washing process, but can also generate micro-nano bubbles in the rinsing process to treat various stains. When used in conjunction with rinsing, the effect is even better. The micro-nano bubble generation and rinsing alternate according to the number of rounds set by the background program, and perform a final stain removal for the user before the dehydration process, which further improves the washing ratio and greatly enhances user satisfaction.

[0043] This embodiment provides a micro-nano bubble generator for garment processing. Through high-speed shearing technology, it rapidly shears gases such as air or oxygen into micro-nano-sized bubbles. These micro-nano bubbles are evenly distributed in water, forming a foam-like structure. When garments are immersed in water, they are continuously enveloped by these micro-nano bubbles. The rapid bursting of these bubbles in the water flow generates impact that penetrates deep into the garment fibers, helping to remove stains. Simultaneously, the impact of these bursting bubbles also has a sterilizing effect.

[0044] In this embodiment, the spray structure of a garment treatment device is positioned above the inner drum. Since the portion of the garment exposed above the water surface does not come into contact with the micro-nano bubbles, a high-concentration mist of mixed detergent is sprayed onto the garment through the spray nozzle, allowing the detergent to be more evenly dispersed above the garment. Spray technology typically combines high pressure and micro-nozzles to atomize water into extremely small droplets. These droplets form a thin detergent film on the surface of the garment, allowing the detergent to penetrate deeper into the garment fibers and improve the washing effect.

[0045] In some embodiments of this invention, when the inner drum rotates, it causes the clothes to rub against the inner drum and also beats the clothes, simulating the friction and tumbling of clothes in water during hand washing.

[0046] The inner cylinder has a small hole at the location of the micro-nano bubble generator. At the same time, a photoelectric sensor is installed at the outlet of the micro-nano bubble generator. Whenever the inner cylinder slowly rotates to the photoelectric sensor, a pulse signal is generated. The micro-nano bubble generator will increase the bubble flow rate and expand into the inner cylinder at high speed, thereby improving the diffusion rate of micro-nano bubbles.

[0047] A flow-guiding structure is added to the outer wall of the inner cylinder. When the inner cylinder rotates, some micro-nano bubbles flow into the inner cylinder under the action of the flow-guiding structure. In this way, the micro-nano bubbles are guided to the front and back sides of the inner and outer cylinders. This allows the micro-nano bubbles, which were originally aggregated and diffused, to diffuse efficiently and quickly to every position, greatly improving the stain removal ability of the micro-nano bubbles.

[0048] The water level in the inner drum is maintained at a low position, just enough to soak the clothes. The slow rotation of the inner drum, combined with micro-nano bubble and spray technology, not only provides a powerful cleaning effect but also reduces physical damage to clothes. Because the impact of micro-nano bubbles is gentle, and the spray structure is fine, the spray falls slowly in a uniform mist form, without causing abrasion to clothes. The application of this technology in washing machines enables efficient and gentle washing of clothes.

[0049] After the washing cycle, the rubbing stage generates a large amount of foam. The micro-nano bubbles allow the detergent foam to clean the clothing fibers more deeply. Combined with the spray above, the clothes remain enveloped in detergent foam. At the same time, the inner drum rotates gently, continuously tumbling the clothes in the detergent foam, simulating hand washing, providing an efficient and environmentally friendly method for cleaning clothes.

[0050] Secondly, during the rinsing cycle after the main wash cycle, the micro-nano bubble generator continues to function. Each time the light sensor detects a beam of light at the inner drum's opening, it increases the amount of micro-nano bubbles generated. Specifically, when the inner drum's opening rotates to the light sensor, a pulse signal is triggered, increasing the amount of micro-nano bubbles produced. The flow-guiding structure on the outer wall of the inner drum also accelerates the diffusion of micro-nano bubbles, enhancing cleaning power. By setting the number of cycles, rinsing and micro-nano bubble generation can alternate.

[0051] The following is for reference Figures 1 to 4 This invention describes a garment processing device.

[0052] A garment processing device includes an inner drum 1, an outer drum 2, and a bubble generating device 3. The bubble generating device 3 includes a bubble outlet 31, which is disposed between the inner drum 1 and the outer drum 2. The bubble outlet 31 is configured to deliver bubbles into the outer drum 2, specifically delivering bubbles between the inner drum 1 and the outer drum 2. During the process of delivering bubbles into the outer drum 2 by the bubble generating device 3, some bubbles will be delivered into the inner drum 1.

[0053] Specifically, the garment processing equipment also includes a housing, a bubble generating device 3 installed between the housing and the outer cylinder 2 and fixed on the housing, and a bubble outlet end 31 protruding from the outside of the outer cylinder 2 to the inside of the outer cylinder 2.

[0054] like Figure 1 , Figure 2 The diagram of the garment processing equipment shown is as follows: Figure 3The schematic diagram of the flow guiding structure shown illustrates that in a drum washing machine, the aforementioned bubble generating device 3 is installed between the inner drum 1 and the outer drum 2. A flow guiding structure 4 is provided on the outer wall of the inner drum 1. The bubble generating device 3 delivers bubbles to the interior of the outer drum 2 and the interior of the inner drum 1. During the rotation of the inner drum 1, the flow guiding structure 4 on the outer wall of the inner drum 1 guides the bubbles between the outer drum 2 and the inner drum 1, preventing microbubbles from remaining between the outer and inner drums.

[0055] In some embodiments of this invention, the garment processing device further includes a flow guiding structure 4, which is disposed on the outer wall of the inner cylinder 1 and extends from the outer wall of the inner cylinder 1 toward the outer cylinder 2; the inner cylinder 1 includes water permeable holes 5, and the flow guiding structure 4 is disposed between the water permeable holes 5.

[0056] Specifically, the inner drum of the garment processing equipment includes multiple water-permeable holes 5, which are evenly arranged around the perimeter of the inner drum 1, with a flow guide structure 4 between at least two water-permeable holes 5. In a preferred embodiment, eight flow guide structures 4 are evenly and at equal intervals arranged on the outer wall of the inner drum 1. The length of the flow guide structure 4 can be set as needed.

[0057] like Figure 2 The schematic diagram of the flow guiding structure of a garment processing device shown is a flow guiding structure 4 between the inner cylinder 1 and the outer cylinder 2 as seen in the front view of the garment processing device. The side view shows the flow guiding structure 4 extending from the opening of the inner cylinder 1 towards the bottom of the inner cylinder 1. The flow guiding structure 4 includes a flow guiding structure protrusion 41 and a flow guiding structure bottom wall 42. The flow guiding structure protrusion 41 protrudes from the inner wall of the inner cylinder 1 towards the outer cylinder 2, which can better guide the microbubbles between the inner cylinder 1 and the outer cylinder 2.

[0058] Figure 3 The following is shown Figure 2 The enlarged schematic diagram of region A, i.e., the schematic diagram of the flow guiding structure 4, shows that the bottom wall 42 of the flow guiding structure is fitted to the outer wall of the inner cylinder 1, and there is a preset distance between the protrusion 41 of the flow guiding structure and the outer cylinder 2. Therefore, the flow guiding structure 4 is set on the originally smooth outer wall of the inner cylinder 1 to promote better flow of microbubbles between the outer cylinder 2 and the inner cylinder 1. When the inner cylinder 1 rotates at high speed, the flow guiding structure 4 exerts a greater force on the microbubbles between the outer cylinder 2 and the inner cylinder 1. When the inner cylinder 1 rotates at low speed, the flow guiding force of the flow guiding structure 4 on the microbubbles between the outer cylinder 2 and the inner cylinder 1 is smaller than the force when rotating at high speed.

[0059] like Figure 4 As shown, the bubble generating device 3 includes a water inlet 32 ​​and an air inlet 33. The water inlet 32 ​​is connected to the circulating water pipeline of the clothing processing equipment. The bubble generating device 3 also includes a mixing chamber 34. The interior of the mixing chamber 34 is provided with a spiral stirring structure, which is used to mix and shear the water flowing in from the water inlet 32 ​​and the gas drawn in from the air inlet 33 to form micro-nano bubbles.

[0060] For example, when multiple bubble generating devices 3 are provided, multiple bubble generating devices 3 can be installed at multiple locations between the inner cylinder 1 and the outer cylinder 2, such as at least two bubble generating devices 3. The amount of micro-nano bubbles transported between the outer cylinder 2 and the inner cylinder 1 will also increase. To better transport the remaining bubbles between the outer cylinder 2 and the inner cylinder 1 to the inner cylinder 1, multiple flow guiding structures 4 can be provided. For example, when one bubble generating device 3 is provided, the corresponding number of flow guiding structures 4 is eight. Then, when two bubble generating devices 3 are provided, at least nine flow guiding structures 4 are provided, with nine to sixteen being exemplary. In this way, when conveying bubbles to the inner cylinder 1, the corresponding flow guiding structures 4 play a better guiding role in conjunction with the amount of bubbles transported by the bubble generating devices 3.

[0061] Alternatively, in a top-loading washing machine, an air bubble generator 3 can be installed between the inner drum 1 and the outer drum 2, and a flow guiding structure 4 can be provided on the outer wall of the inner drum 1. The air bubble generator 3 does not need to rotate with the inner drum 1.

[0062] The space between the inner drum 1 and the outer drum 2 inherently involves water circulation and air pressure balance during equipment operation. The bubble generator, installed between the inner drum 1 and the outer drum 2, can better utilize the water flow and air pressure environment in this area. During microbubble generation, the existing water flow dynamics between the outer drum 2 and the inner drum 1 can be used to distribute the microbubbles more evenly in the water. Simultaneously, the generation and release of microbubbles can be optimized based on the air pressure between the inner drum 1 and the outer drum 2, ensuring that the size and quantity of microbubbles better meet washing requirements.

[0063] In some embodiments of this invention, holes are made on the side wall of the inner cylinder 1 in the direction of the bubble outlet 31 of the bubble generator 3. A light sensor 7 is provided on the bubble outlet 31 of the bubble generator 3. The light sensor 7 can sense not only the light beam of the water-permeable hole 5, but also the light beam of the hole.

[0064] Combined with appendix Figure 1 To further explain the solution of creating holes in the inner cylinder 1, multiple holes can be set. When only one hole is set, it is equivalent to the light sensor of the bubble generator sensing a beam of light once every time the inner cylinder 1 rotates.

[0065] In some embodiments of this invention, the garment treatment device further includes a spraying structure 6, which is installed at the nozzle and is used to spray garment treatment agent into the inner drum 1.

[0066] The light sensor 7 generates a sensing signal when it detects light at the hole. The light sensor 7 can also be used to sense light beams from the permeable holes.

[0067] When the light sensor 7 sends a sensing signal, the bubble outlet 31 emits a microbubble.

[0068] The spray structure 6 can evenly spray the laundry detergent onto the clothes being treated in the inner drum 1. For example, when the parts of the clothes above the water surface cannot come into contact with the micro-nano bubbles, a high-concentration mist of mixed detergent can be sprayed onto the clothes through the spray nozzles of the spray structure 6. The laundry detergent can include different types such as detergent and fabric softener; the detergent can better break down stains on the clothes. Compared to directly adding the laundry detergent into the drum, which may result in localized accumulation and uneven distribution, spraying the laundry detergent into the inner drum 1 ensures that the detergent covers the clothes more evenly, avoiding situations where some areas have too much or too little detergent, thus affecting the washing quality.

[0069] like Figure 4 As shown, the photosensitive sensor 7 generates a sensing signal by sensing the light at the sensing hole or the light beam from the water-permeable hole 5, which serves as a trigger mechanism to precisely control the amount of micro-nano bubbles delivered by the bubble outlet 31. Sensing the light at the sensing hole is preferred because the hole is designed to distinguish it from the water-permeable hole. In some preferred embodiments of this example, when a hole is created, it is sensed once when the inner cylinder 1 rotates once. Therefore, the number of times the bubble delivery amount of the bubble generating device 3 increases after the inner cylinder 1 rotates once is one. In other preferred embodiments, the water-permeable hole can be used as the sensing point for the photosensitive sensor 7. Since the distance between at least two water-permeable holes 5 in the inner cylinder 1 is small, this also increases the number of times the photosensitive sensor 7 increases the bubble delivery amount of the bubble generating device 3. That is, the number of times the bubble delivery amount of the bubble generating device 3 increases after the inner cylinder 1 rotates once is at least two. In other preferred embodiments, the water-permeable holes 5 in the inner cylinder 1 can be marked so that the number of times the bubble delivery amount of the bubble generating device 3 increases or decreases under the action of the photosensitive sensor can be adjusted.

[0070] In some embodiments of this invention, the light sensor 7 can be an infrared sensor device. Utilizing infrared light to detect permeable holes or openings improves sensing accuracy. The infrared light emitted by the sensor illuminates the surface of the target object. When the infrared light encounters a permeable hole or opening, its optical properties, such as reflection and absorption, differ due to the different material structure at the opening compared to the surrounding solid parts. For example, a complete solid surface mostly or regularly reflects infrared light, while holes or permeable holes cause changes in the scattering, refraction, or absorption of infrared light. Therefore, even with clothing obstructing the view, the light sensor can detect the permeable hole or opening. In the optimal embodiment of this invention, when installing a bubble generator, the opening is used as the sensing position of the light sensor. This is because the opening position of the opening can be set according to the position corresponding to the bubble outlet of the bubble generator, not limited to the fixed position of the permeable hole, increasing flexibility. When at least two bubble generators are installed, both the holes and the water permeable holes can be used as sensing positions for the photosensitive sensors. For example, when one bubble generator is installed, if the bubble outlet of the bubble generator needs to correspond to the water permeable hole, the photosensitive sensor set on the bubble outlet of this bubble generator is used to sense the position of the water permeable hole. When another bubble generator is installed, if the bubble outlet of the bubble generator does not need to correspond to the water permeable hole, a hole is made in the inner cylinder at the position corresponding to the bubble outlet of the bubble generator, and the photosensitive sensor set on the bubble outlet of this bubble generator is used to sense the position of the hole.

[0071] In some schemes of this embodiment, with Figures 1 to 4 Based on the garment processing equipment shown, a control method for the garment processing equipment is provided.

[0072] like Figures 5 to 6 As shown, during the bubble washing program, the bubble generating device is controlled to deliver bubbles into the inner cylinder. In response to the sensing signal triggered by the light sensor, the bubble quantity parameter of the bubble washing program is increased.

[0073] The bubble wash program includes a process of spraying laundry detergent. During the process of the bubble generator delivering bubbles to the inner drum, the spraying structure is controlled to spray laundry detergent into the inner drum.

[0074] Before the rinsing cycle of the washing program starts, the spray structure is controlled to spray the garment treatment agent into the drum;

[0075] After the rinsing program starts, the rinsing process and the bubble washing process run alternately.

[0076] Specifically, during the washing program, if the main wash cycle is determined to be completed, the bubble wash cycle is then started. The bubble wash cycle includes the spraying of laundry detergent; during the bubble wash cycle, laundry detergent is sprayed into the drum. That is, the bubble wash cycle involves the bubble generator supplying bubbles to the inside of both the outer and inner drums, while the spraying structure simultaneously sprays laundry detergent into the inner drum.

[0077] The bubble wash program includes a bubble quantity parameter that is adjusted in response to a light sensor signal. Specifically, the light sensor generates a signal each time it detects a beam of light at the water permeability holes or openings in the inner drum. The controller then controls the bubble generator to increase the bubble delivery rate based on this signal. This ensures that the total number of bubbles inside the outer drum remains within a certain range during the inner drum's rotation, preventing areas from being ineffectively filled or not fully covered by bubbles, thus affecting the washing effect.

[0078] Each time the light sensor detects a beam of light at the water-permeable hole or opening in the inner drum, it generates a sensing signal, increasing the amount of air bubbles delivered. This means that the water-permeable hole or opening is exposed, and increasing the amount of air bubbles delivered at this time makes it easier for the air bubbles to fully enter the inner drum. The impact force of the air bubbles on the clothes can more effectively remove stains from the clothes, enhancing the stain removal ability.

[0079] If the bubble wash program is determined to be finished, the rinsing program will be run. The rinsing program includes a rinsing process and a bubble wash process, which are run alternately.

[0080] During the bubble washing process, the bubble quantity parameter is increased in response to the sensing signal from the light sensor.

[0081] For example, a washing program includes a main wash program, a rinsing program, a spin-drying program, and a draining program. The main wash program is the stage in which the clothes are washed with water containing a laundry detergent.

[0082] After the main wash cycle ends, the micro-nano bubble generator produces bubbles, the inner drum rotates, and induction signals are triggered at the holes. The controller then controls the bubble generator to increase the amount of bubbles produced. The flow-guiding structure on the outside of the inner drum enhances bubble diffusion, which, together with the rotation of the inner drum, simulates hand washing. At the same time, the spraying structure sprays a mist of detergent, covering the surface of the clothes with the mist of detergent. The flow-guiding structure can be a flow guide rib.

[0083] The running time of the bubble wash program can be further limited based on the weight or material of the clothes in the drum. Furthermore, in some embodiments of this program, the bubble wash program can run once before the main wash program begins and once or more after the main wash program ends. This allows for better contact between the clothes and the laundry detergent, removing stubborn stains and improving the washing efficiency.

[0084] In some embodiments of this invention, the provided garment processing device includes one or more of the following components: a processing component, a memory, a power component, a sensor component, a communication component, and a processor.

[0085] The processing component typically controls the overall operation of the garment processing equipment, including related operations such as display, audible alerts, water filling programs, soaking programs, washing programs, rinsing programs, spin-drying programs, drying programs, disinfection programs, and sterilization programs. The processing component may include one or more processors to execute instructions to complete all or part of the steps of the aforementioned garment processing equipment control methods. Furthermore, the processing component may include one or more modules to facilitate interaction between the processing component and other components.

[0086] The memory is configured to store various types of data to support the operation of a multi-drum washing machine. Examples of this data include instructions for any application or method operating on the garment handling equipment, historical washing data, etc. The memory can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EPROM), erasable programmable read-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, magnetic disk, or optical disk.

[0087] The power components provide power to the various components of the garment handling equipment.

[0089] The communication components are configured to facilitate wired or wireless communication between the garment handling device and other devices. The garment handling device can access wireless networks based on communication standards, such as WiFi, 2G, or 3G, or combinations thereof.

[0090] In an exemplary embodiment, the garment processing device may be implemented by one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic components to execute the control method of the garment processing device described above.
