Abstract
Description
Technical Field
[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a control method for clothing processing equipment and clothing processing equipment. Background Technology
[0002] Washing machines or washer-dryer combos, as garment processing devices, are increasingly favored by users for their convenience and speed. When washing clothes, these devices heat the water to improve cleaning efficiency when the inlet water temperature is low, resulting in high temperatures inside the drum. This leads to high moisture content in the clothes and poor spin-drying efficiency. Normally, the drum speed is increased to improve spin-drying efficiency. However, when there are too few clothes in the drum, insufficient centrifugal force significantly reduces the centrifugal force required for spin-drying, resulting in poor spin-drying efficiency even for lightweight garments. Furthermore, during the drying stage, lightweight garments tend to stick to the back wall of the drum due to the small number of clothes, preventing them from moving with the drum and reducing the contact area between the clothes and the hot air, thus lowering drying efficiency. Therefore, there is an urgent need to design a control method for garment processing equipment that can improve both spin-drying and drying efficiency. Summary of the Invention
[0003] The purpose of this invention is to provide a control method and a garment processing device, which solves the technical problems in the prior art, such as unsatisfactory dehydration efficiency and the small contact area between the garment and the hot air during the drying process, which reduces the drying efficiency.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] This invention provides a control method for a garment processing device, comprising the following steps:
[0006] Obtain the dry weight of the garment and determine whether it is a lightweight garment;
[0007] If the garments are lightweight, a lightweight garment processing program is executed after the washing cycle: during the spin-drying process, the hot and humid air inside the washing drum of the garment processing equipment is cooled; during the drying process, the rotation speed of the washing drum is adjusted to N times the rotation speed of the washing drum in the normal drying program, where N is greater than 1.
[0008] The control method of this garment processing equipment is as follows: When the garments to be processed are lightweight garments, a lightweight garment processing program is executed after the washing program. During the dehydration process, the humid and hot air inside the washing drum of the garment processing equipment is cooled down to reduce the high temperature inside the washing drum caused by the heating of the washing water, thereby improving the condensation effect and thus improving the dehydration efficiency. During the drying process, the rotation speed of the washing drum is adjusted to N times the rotation speed of the washing drum in the normal drying program, so that the garments can rotate to the middle height with the water-repelling blades of the washing drum and be shaken off, increasing the contact area between lightweight garments and hot air and improving the drying efficiency.
[0009] As a preferred embodiment of the control method for the aforementioned garment processing equipment, obtaining the dry weight of the garments and determining whether they are lightweight garments includes the following steps:
[0010] The dry weight of clothing is obtained by fuzzy weighing.
[0011] Determine if the dry weight is less than 1 / M of the rated washing capacity;
[0012] If so, then it falls under the category of lightweight clothing.
[0013] The dry weight of clothes is obtained by using fuzzy weighing, which makes it easy to obtain the dry weight of clothes. When the dry weight is less than 1 / M of the rated washing capacity, it is considered a light garment. This method is used to determine whether a garment is a light garment and then run the corresponding program.
[0014] As a preferred embodiment of the control method for the aforementioned garment processing equipment, if the weight of a certain number of garments is not less than 1 / M of the rated washing capacity, then they are not considered lightweight garments, and a regular garment processing program is executed after the washing program.
[0015] For items that are not lightweight, simply follow the regular laundry treatment after the wash cycle.
[0016] As a preferred embodiment of the control method for the aforementioned garment processing equipment, the range of 1 / M is 1 / 10 to 1 / 8.
[0017] The above settings can effectively dehydrate and dry clothes within the corresponding range.
[0018] As a preferred embodiment of the control method for the aforementioned garment processing equipment, the cooling of the hot and humid air inside the washing drum of the garment processing equipment during the dehydration process includes the following steps:
[0019] Cooling air is introduced into the washing drum to cool down the hot and humid air inside the drum.
[0020] Cooling the hot and humid air inside the washing drum by introducing cooling air is easy to achieve.
[0021] As a preferred embodiment of the control method for the aforementioned garment processing equipment, the condenser of the garment processing equipment is connected to a fan, and the condenser and the fan are respectively connected to the washing drum to form an air circulation channel, wherein the cooling air is circulated into the washing drum.
[0022] The above method allows for the cooling of hot and humid air inside the washing drum using existing components.
[0023] As a preferred embodiment of the control method for the aforementioned garment processing equipment, the fan speed is 1 / P of the normal operating speed, where P is greater than 1.
[0024] The above settings prevent clothes from being blown to the back of the drum and from detaching from the water-repellent blades, thus affecting the dehydration effect.
[0025] As a preferred embodiment of the control method for the aforementioned garment processing equipment, the range of 1 / P is 1 / 4 to 1 / 3.
[0026] The above settings can both cool down the hot and humid air inside the washing drum and prevent clothes from being blown to the back of the drum, thus avoiding them from falling off the deflector blades and affecting the dehydration effect.
[0027] In a preferred embodiment of the control method for the aforementioned garment processing equipment, the range of N is 2-4.
[0028] The above settings can effectively improve drying efficiency.
[0029] The present invention also provides a garment processing device, which applies the control method of the garment processing device described above.
[0030] This garment processing equipment improves the drying efficiency of lightweight garments through the control method described above.
[0031] The beneficial effects of this invention are:
[0032] The control method for the garment processing equipment proposed in this invention, when the garments to be processed are lightweight garments, executes a lightweight garment processing program after the washing program: During the dehydration process, the humid and hot air inside the washing drum of the garment processing equipment is cooled down, reducing the high temperature inside the washing drum caused by the heating of the washing water, improving the condensation effect, and thus improving the dehydration efficiency; During the drying process, the rotation speed of the washing drum is adjusted to N times the rotation speed of the washing drum in the normal drying program, allowing the garments to rotate to the middle height with the water-repelling blades of the washing drum and be shaken off, increasing the contact area between the lightweight garments and the hot air, and improving the drying efficiency.
[0033] The garment processing equipment proposed in this invention improves the dehydration and drying efficiency of lightweight garments through the control method described above. Attached Figure Description

[0040] Example 1:
[0041] Washing machines or washer-dryer combos, as garment processing devices, are increasingly favored by users for their convenience and speed. When washing clothes, these devices heat the water to improve cleaning efficiency when the inlet water temperature is low, resulting in high temperatures inside the drum. This leads to high moisture content in the clothes and poor spin-drying efficiency. Normally, the drum speed is increased to improve spin-drying efficiency. However, when there are too few clothes in the drum, insufficient centrifugal force significantly reduces the centrifugal force required for spin-drying, resulting in poor spin-drying efficiency even for lightweight garments. Furthermore, during the drying stage, lightweight garments tend to stick to the back wall of the drum due to the small number of clothes, preventing them from moving with the drum and reducing the contact area between the clothes and the hot air, thus lowering drying efficiency. Therefore, there is an urgent need to design a control method for garment processing equipment that can improve both spin-drying and drying efficiency.
[0042] To solve the above problems, such as Figure 1 As shown, this embodiment provides a control method for a garment processing device, including the following steps:
[0043] S11. Obtain the dry weight of the clothing and determine whether it is lightweight clothing;
[0044] S12. If the garments are lightweight, a lightweight garment processing program will be executed after the washing program: During the spin-drying process, the hot and humid air inside the washing drum of the garment processing equipment will be cooled; during the drying process, the rotation speed of the washing drum will be adjusted to N times the rotation speed of the washing drum in the normal drying program, where N is greater than 1.
[0045] The control method of this garment processing equipment is as follows: When the garments to be processed are lightweight garments, a lightweight garment processing program is executed after the washing program. During the dehydration process, the humid and hot air inside the washing drum of the garment processing equipment is cooled down to reduce the high temperature inside the washing drum caused by the heating of the washing water, thereby improving the condensation effect and thus improving the dehydration efficiency. During the drying process, the rotation speed of the washing drum is adjusted to N times the rotation speed of the washing drum in the normal drying program, so that the garments can rotate to the middle height with the water-repelling blades of the washing drum and be shaken off, increasing the contact area between lightweight garments and hot air and improving the drying efficiency.
[0046] Example 2:
[0047] This embodiment provides a control method for a garment processing device. This embodiment is an improvement based on Embodiment 1, such as... Figure 2 As shown, the control method for the garment processing equipment includes the following steps:
[0048] S21. Obtain the dry weight of the clothes by fuzzy weighing;
[0049] The dry weight of clothes is easily obtained by using fuzzy weighing. Obtaining the dry weight of clothes using fuzzy weighing is a standard operation in garment processing equipment; the specific steps and procedures for obtaining the dry weight of clothes using fuzzy weighing will not be detailed here.
[0050] It should be noted that the weight obtained by fuzzy weighing is the weight of the clothes before they were submerged in water, at which point no water had entered the garment and the clothes were not yet wet.
[0051] S22. Determine if the dry weight is less than 1 / M of the rated washing capacity;
[0052] Rated washing capacity is an important indicator for evaluating laundry processing equipment. It represents the maximum weight of laundry that the equipment can handle in a single wash cycle. This data is usually measured in kilograms, providing users with a clear reference.
[0053] By determining whether the obtained dry weight is less than 1 / M of the rated washing capacity, it can be determined whether the clothes to be treated are lightweight. Comparing these values makes it easy to conclude whether the clothes are lightweight, allowing for targeted treatment when they are indeed lightweight.
[0054] S231. If so, then it is a light garment and a light garment treatment program will be performed after the washing program.
[0055] After numerical comparison, it was found that the weight of some garments was less than 1 / M of the rated washing capacity, indicating that the garments to be treated were lightweight garments. Therefore, a lightweight garment treatment program was executed after the washing program.
[0056] S232. If the weight of a certain number of garments is not less than 1 / M of the rated washing capacity, then they are not considered lightweight garments. After the washing program, the regular garment processing program will be executed until the program ends.
[0057] After numerical comparison, if the weight of the garments is not less than 1 / M of the rated washing capacity, and the garments to be processed are not lightweight, then the regular garment processing program, i.e. the regular spin-drying and drying program, should be executed after the washing program until the end.
[0058] The range of 1 / M is 1 / 10 to 1 / 8, and this range allows for better dehydration and drying of clothes within the corresponding range. For example, 1 / M can be 1 / 10, 1 / 9, 1 / 8, etc. In this embodiment, clothes with a dry weight less than 1 / 10 of the rated washing capacity are considered lightweight clothes. In other embodiments, the range of 1 / M can be adjusted and is not limited to 1 / 10 to 1 / 8.
[0059] S24. During the dehydration process, cooling air is introduced into the washing drum to cool down the hot and humid air inside the drum.
[0060] Cooling air is introduced into the washing drum to lower the temperature of the hot and humid air inside. This method is easy to implement. By introducing cooling air into the washing drum, the hot and humid air inside can be condensed, reducing the moisture content of lightweight clothes, thereby improving the dehydration efficiency and quality of lightweight clothes.
[0061] Specifically, the condenser of the garment processing equipment is connected to a fan, and both the condenser and the fan are connected to the washing drum to form an air circulation channel. The condenser cools the circulating air to form cooled air, which is then forced into the washing drum through the inlet end by the fan to cool the hot and humid air inside. The cooled air then re-enters the condenser under the action of the fan, forming a cycle. This air circulation channel formed by the condenser, fan, and washing drum effectively cools the hot and humid air inside the washing drum, utilizing existing components of the garment processing equipment without requiring additional components.
[0062] Optionally, during the dehydration stage, the fan speed is 1 / P of the normal operating speed, where P is greater than 1. Preferably, 1 / P ranges from 1 / 4 to 1 / 3. This setting can both cool the hot and humid air inside the washing drum and prevent the clothes from being blown to the back of the drum, thus avoiding the clothes detaching from the deflector blades and affecting the dehydration effect. Optionally, 1 / P can be 1 / 4, 7 / 24, 1 / 3, etc. In this embodiment, the fan speed is 1 / 4 of the normal operating speed. The normal operating speed is the fan speed during the drying process in a conventional clothing processing program.
[0063] It should be noted that the range of 1 / P can be adjusted according to needs, and is not limited to 1 / 4 to 1 / 3.
[0064] S25. During the drying process, the rotation speed of the washing drum is adjusted to N times the rotation speed of the washing drum in the normal drying program.
[0065] Optionally, N ranges from 2 to 4, for example, N can be 2, 2.5, 3, 3.5, 4, etc. In this embodiment, the rotation speed of the washing drum is adjusted to three times the rotation speed of the washing drum in the normal drying program, so that lightweight clothes can adhere to the circumferential wall of the washing drum and be shaken off as the water-repelling blades of the washing drum rotate to the middle height, thereby increasing the contact area between the lightweight clothes and the hot air and improving the drying efficiency. The normal drying program is the drying program in a conventional clothing handling process.
[0066] It should be noted that the range of N is not limited to 2-4 and can be adjusted according to requirements.
[0067] S26, Program ends.
[0068] Once the drying process is complete, the entire garment processing procedure is finished.
[0069] Example 3:
[0070] The present invention also provides a garment processing device, which uses the control method of the garment processing device in any of the above embodiments to process garments.
[0071] Specifically, the garment processing equipment includes a housing, an outer drum housed within the housing, and a washing drum rotatably housed within the outer drum. Garments to be washed are placed into the washing drum for washing, spin-drying, and drying processes. A condenser and a fan are located inside the housing and outside the outer drum, connected to each other and also connected to the washing drum to form a circulation path. Air circulates within this path, and the condenser cools the circulating air to create cooled air. This cooled air enters the washing drum through an inlet, further cooling the hot and humid air inside. It then re-enters the condenser under the action of the fan, completing the circulation. This air circulation path, formed by the condenser, fan, and washing drum, effectively cools the hot and humid air inside the washing drum. This method utilizes existing components of the garment processing equipment to cool the hot and humid air within the washing drum, eliminating the need for additional components and reducing the cost of retrofitting the garment processing equipment.
[0072] Alternatively, the garment handling equipment can be a washing machine or a washer-dryer combo.
[0073] The garment processing equipment processes garments using the control method of the garment processing equipment in any of the above embodiments, thereby improving the dehydration and drying efficiency of lightweight garments.
[0074] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
