[0002] As the most widely used household appliance in people's daily life, clothes processing equipment helps people get rid of the trouble of washing and drying clothes, bringing great convenience to people. However, with the increasing washing functions and types of clothes processing equipment, it is more suitable for users' different washing needs. At the same time, when dirt is formed between the inner and outer drums, it also increases the difficulty and cost of disassembling the inner drum and cleaning the outer drum.

[0003] Therefore, the existing clothes processing equipment adopts an inner drum without a dehydration hole, so that the washing water is only in the inner drum during the washing process, which completely solves the problem of dirt formed between the inner drum and the outer drum of the clothes processing equipment due to water accumulation. However, during the drying process, the clothes processing equipment dries by heating air, and the inner drum and the clothes inside are heated unevenly, resulting in low drying efficiency.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0052] like Figures 1 to 8 As shown, the present invention provides a clothing processing device and a control method thereof, wherein a heat conducting device 3 is arranged on the outer wall and / or the inner wall of an inner drum 2 and has a cavity for accommodating a heat conducting medium, so that the inner drum 2 without a dehydration hole and the clothes therein are heated evenly, the drying efficiency is high, and the stability and reliability of drying the inner drum 2 are improved.

[0053] Embodiment 1

[0054] like Figures 1 to 5 As shown, this embodiment provides a clothes processing device, including:

[0055] Inner drum 2, which can independently hold water during washing;

[0056] A heat conducting device 3, arranged on the outer wall and / or the inner wall of the inner tube 2, having a cavity for containing a heat conducting medium;

[0057] The heating device heats the inner cylinder 2 by heating the heat-conducting medium in the cavity.

[0058] The heat conducting device 3 is arranged on the outer wall and / or inner wall of the inner drum 2 and has a cavity for accommodating a heat conducting medium, so that the inner drum 2 without a dehydration hole and the clothes therein are heated evenly, the drying efficiency is high, and the stability and reliability of drying the inner drum 2 are improved.

[0059] In this embodiment, the heat conducting device 3 and the inner side and / or outer side of at least part of the side wall of the inner tube 2 enclose the cavity. Figure 1 As shown, the heat conducting device 3 encloses part of the outer side wall to form the cavity. By arranging the heat conducting device 3 between the inner tube 2 and the outer tube 4, the tube wall of the outer tube 4 is exposed to water or water vapor as little as possible, thereby reducing dirt and bacterial reproduction, and making the clothing processing equipment more stable and reliable.

[0060] In this embodiment, the heating device is an electromagnetic heating device 32; at least a part of the heat conducting device 3 is made of a metal material that can generate eddy currents in an alternating magnetic field.

[0061] Specifically, in this embodiment, the electromagnetic heating device 32 is arranged on the bottom of the side wall of the outer drum 4, so that the electromagnetic heating device 32 generates an alternating magnetic field, so that at least a part of the heat conducting device 3 generates eddy currents in the alternating magnetic field, thereby generating heat and heating the heat conducting medium. Therefore, the electromagnetic heating device 32 can realize contactless heating, thereby realizing that the clothing processing equipment does not affect the rotation of the inner drum 2 during the drying process, and realizes efficient and rapid heating through the electromagnetic heating principle.

[0062] More specifically, the electromagnetic heating device 32 is embedded in the bottom of the side wall of the outer tube 4, so that part of the surface of the electromagnetic heating device 32 extends into the inner side of the outer tube 4 and is spaced apart from the heat conducting device 3, further improving the heating efficiency of the electromagnetic heating device 32 on the heat conducting medium in the heat conducting device 3.

[0063] Therefore, contactless heating can be achieved by the electromagnetic heating device 32, thereby achieving that the rotation of the inner drum 2 is not affected during the drying process of the clothes processing device, and the efficiency of heating the heat-conducting medium is improved, thereby further improving the drying efficiency of the clothes processing device. In addition, the temperature of the heat-conducting medium can be better controlled by the electromagnetic heating device 32.

[0064] In this embodiment, Figures 1 to 4 As shown, the cavity of the heat conducting device 3 is provided with a liquid inlet and an exhaust port, the liquid inlet is provided with a liquid inlet portion that conducts one-way from the outside of the cavity to the inside thereof, and the exhaust port is provided with an exhaust portion 34 that conducts one-way from the inside of the cavity to the outside thereof.

[0065] The liquid inlet and the exhaust port make the cavity of the heat conducting device 3 more airtight. When the heat conducting medium inside is heated and pressurized, part of the gas can be discharged, thereby making the heat conducting device 3 more reliable and stable.

[0066] In this embodiment, Figures 2 to 4As shown, the liquid inlet part includes: a one-way liquid inlet valve 31, used for blocking the liquid inlet; a water inlet pipe 33, used for pushing the one-way liquid inlet valve 31 to open the liquid inlet; a first motor 35, used for driving the water inlet pipe 33 to reciprocate; the first motor 35 drives the water inlet pipe 33 to be inserted into the liquid inlet, and pushes the one-way liquid inlet valve 31 to open the liquid inlet; the first motor 35 drives the water inlet pipe 33 to be removed from the liquid inlet, the water inlet pipe 33 is separated from the one-way liquid inlet valve 31, and the one-way liquid inlet valve 31 re-blocks the liquid inlet.

[0067] Specifically, the channels of the one-way liquid inlet valve 31 and the exhaust part 34 are both provided with elastic elements and blocking elements, the blocking element compresses the elastic element to open the channel, and the elastic element resets the blocking element to block the channel. The water inlet cannula 33 is a hard hollow pipe, which is inserted into the one-way liquid inlet valve 31 and pushes the blocking element to compress the elastic element to open the channel.

[0068] More specifically, in the process of the electromagnetic heating device 32 heating the heat-conducting medium in the heat-conducting device 3, the heat-conducting medium expands due to temperature increase, and then when the pressure in the cavity of the heat-conducting device 3 reaches a certain value, the sealing member in the exhaust part 34 is pushed to compress the elastic element, and then the channel is opened to exhaust and reduce pressure, so that there is enough space in the cavity to allow more heat-conducting medium to be fully heated and heated, thereby ensuring rapid heating and making the heat-conducting device 3 more reliable and stable when the temperature of the heat-conducting medium is high.

[0069] In a specific application of this embodiment, the water inlet pipe 33 is connected to the water inlet system of the washing equipment, so that the heat transfer medium introduced into the heat transfer device 3 by the liquid inlet part is liquid water. The steam discharged from the heat transfer device 3 by the exhaust part 34 is cooled and liquefied between the inner tube 2 and the outer tube 4, and is discharged from the outer tube 4 to the drain outlet of the drain device 5 together with the washing water.

[0070] Therefore, through the water inlet pipe 33 and the first motor 35, the heat transfer medium can be input when the heat transfer device 3 is arranged on the inner side of at least part of the side wall of the inner tube 2, while ensuring that there is no heat transfer medium between the inner tube 2 and the outer tube 4.

[0071] Specifically, Figures 2 to 4 As shown, the water inlet cannula 33 is arranged through the outer cylinder 4, and the first motor 35 is arranged on the outer wall of the outer cylinder 4. More specifically, the first motor 35 drives the water inlet cannula 33 to reciprocate through a worm gear mechanism.

[0072] In this embodiment, Figure 1 and 5As shown, the clothing processing device further includes: a vacuum device 74, a dynamic sealing device 75 and a transmission shaft 62; the transmission shaft 62 is connected to the inner drum 2, and an airflow channel connecting the inner and outer sides of the inner drum 2 is arranged inside the transmission shaft 62, and the dynamic sealing device 75 is arranged at one end of the airflow channel located outside the inner drum 2; the vacuum device 74 is connected to the inner part of the inner drum 2 through the airflow channel. The transmission shaft 62 is connected to the second motor 71, so that the second motor 71 drives the inner drum 2 to rotate.

[0073] In this embodiment, Figure 1 and 5 As shown, one end of the dynamic sealing device 75 is rotatably sealedly connected to the ventilation duct 73 of the vacuum pumping device 74, and the other end is connected to the port of the air flow channel.

[0074] During the drying process, the ventilation duct 73 of the vacuum device 74 is fixed, while the transmission shaft 62 rotates under the drive of the second motor 71. By providing a dynamic sealing device 75, the connection between the ventilation duct 73 and the air flow channel can achieve relative rotation and ensure the airtightness of the connection, thereby improving the vacuuming efficiency and the drying efficiency of the inner drum 2.

[0075] Specifically, Figure 5 As shown, the second motor 71 directly drives the transmission shaft 62 by frequency conversion, and a dynamic sealing device 75 is sleeved on the end of the transmission shaft 62 and inserted into the ventilation duct 73 of the vacuum device 74, so that the dynamic sealing device 75 blocks the gap between the inner wall of the ventilation duct 73 and the outer wall of the transmission shaft 62. More specifically, the dynamic sealing device 75 is a dynamic sealing ring.

[0076] Therefore, by means of the vacuum device 74 and the sealing device 75, the moisture and air in the inner drum 2 can be extracted while ensuring the airtightness of the inner drum 2, thereby further improving the drying efficiency.

[0077] Specifically, Figure 1 and 5 As shown, an air flow channel is provided at the axis center of the transmission shaft 62. A transmission shaft housing 63 is provided at the outer periphery of the transmission shaft 62 of the inner drum 2, and the transmission shaft housing 63 is provided with at least two bearings 61 to further improve the sealing performance of the sealing connection at the inner drum 2 where the rotating transmission shaft 62 is inserted, so as to further improve the airtightness inside the inner drum 2, thereby further improving its drying efficiency.

[0078] Specifically, the laundry processing device is a drum washing machine, and a machine door 13 is provided on the outer shell 12, and the inner drum 2 is provided with a laundry placement opening 21 at a position corresponding to the machine door 13, for placing the laundry to be washed and / or dried into the inner drum 2 through the laundry placement opening 21. An upper table panel 11 is provided on the upper part of the outer shell 12, and at least two legs 14 are provided at the bottom of the outer shell 12 for supporting the laundry processing device. More specifically, the laundry placement opening 21 is a door structure, which is more convenient for users to put in laundry.

[0079] In this embodiment, the inner drum 2 is provided with a centrifugal valve located on the same side as its clothing placement port 21, and a drain outlet is provided on the outer drum 4 near the centrifugal valve. A drain device 5 and a drain pipeline are provided on the outside of the drain outlet. Through the high-speed rotation of the inner drum 2, the internal water flow is thrown through the centrifugal valve to between the inner drum 2 and the outer drum 4, and is pumped away and discharged through the drain device 5.

[0080] In this embodiment, the drying process of the clothes processing device is as follows: after detecting that the liquid inlet of the heat conducting device 3 is aligned with the water inlet plug 33, the first motor 35 is powered to push the water inlet plug 33 to insert the one-way liquid inlet valve 36, so that the liquid inlet part introduces a certain amount of heat conducting medium into the heat conducting device 3, and then stops the introduction, and the one-way liquid inlet valve 36 is automatically locked by separating the water inlet plug 33 and the one-way liquid inlet valve 31, and the electromagnetic heating device 32 is powered to generate an alternating magnetic field, so that the heat conducting device 3 generates eddy currents in the alternating magnetic field and generates heat;

[0081] When the pressure in the cavity of the heat-conducting device 3 reaches a certain value, the steam of the heat-conducting medium pushes the exhaust part 34 to open, exhaust and reduce pressure, so that the heat-conducting medium continues to rapidly heat up and release heat;

[0082] The heat conducting device 3 conducts heat to the inner drum 2 and the clothes therein. When the heat conducting device 3 reaches the set temperature, the vacuum device 74 is turned on to extract the water vapor and air in the inner drum 2, thereby lowering the boiling point of the water inside the inner drum 2, so that the water on the surface of the clothes evaporates and the water inside the clothes penetrates to the surface and evaporates;

[0083] The inner drum 2 is driven to rotate by the transmission shaft 62, so that the clothes inside are continuously rotated and beaten, and the clothes are evenly heated, which speeds up the drying process.

[0084] After the drying operation time is over, the vacuuming device 74 is stopped, and the vacuuming device 74 and the electromagnetic heating device 32 are turned off.

[0085] Preferably, during the drying process, after the drying operation time reaches the set time, after detecting that the liquid inlet of the heat-conducting device 3 is aligned with the water inlet plug 33, the inner drum 2 stops rotating, and the first motor 35 is powered to push the water inlet plug 33 to insert the one-way liquid inlet valve 36, so that the liquid inlet part re-introduces a certain amount of heat-conducting medium into the heat-conducting device 3. Afterwards, the first motor 35 drives the water inlet plug 33 and the one-way liquid inlet valve 31 to separate, and after the one-way liquid inlet valve 36 is automatically locked, the inner drum 2 starts to continue rotating.

[0086] In this embodiment, the clothing processing equipment also has a preheating part and a condensing part. The preheating part is used to heat the heat-conducting medium to a preheating temperature before drying begins, and when drying starts, the heat-conducting medium at the preheating temperature is passed into the heat-conducting device 3 to further improve the drying efficiency; the condensing part is used to condense the water vapor flowing out of the air flow channel into liquid and discharge it through the main drain pipe of the clothing processing equipment.

[0087] In this embodiment, the heat conducting device 3 is arranged on the outer wall and / or the inner wall of the inner drum 2 and has a cavity for accommodating a heat conducting medium, so that the inner drum 2 without a dehydration hole and the clothes inside thereof are heated evenly, the drying efficiency is high, and the stability and reliability of the drying of the inner drum 2 are improved; the liquid inlet and the exhaust port are used to make the cavity of the heat conducting device 3 have better airtightness, and part of the gas can be discharged during the process of heating and pressurizing the heat conducting medium inside the cavity, thereby making the reliability and stability of the heat conducting device 3 higher; the vacuum device 74 and the sealing device 75 can be used to ensure the airtightness of the inner drum 2 while extracting water vapor and air in the inner drum 2, thereby further improving the drying efficiency.

[0088] Embodiment 2

[0089] like Figures 1 to 6 As shown, this embodiment provides a clothing processing device, and the difference between this embodiment and the first embodiment is that the heat conduction device 3 is arranged on the outer side of the side wall of the inner drum 2 and circumferentially surrounds the side wall to form a cavity for accommodating a heat conduction medium.

[0090] Specifically, Figure 6 As shown, the exhaust port of the chamber and the exhaust portion 34 disposed therein are provided in two groups, and are symmetrically arranged relative to the central axis of the inner tube 2 .

[0091] Therefore, in this embodiment, the inner drum 2 and the clothes therein are heated more evenly, further improving the drying efficiency of the clothes processing device.

[0092] Embodiment 3

[0093] like Figure 1 , 2As shown in , 3, 4, 5 and 7, this embodiment provides a clothing processing device. The difference between this embodiment and embodiment 1 and embodiment 2 is that the heat conducting device 3 is arranged on the inner side of part of the side wall of the inner drum 2 to form a cavity for accommodating a heat conducting medium.

[0094] In this embodiment, the heat conducting device 3 directly contacts the clothes, which enhances the efficiency of heat transfer and further improves the drying efficiency of the clothes processing device.

[0095] Specifically, Figure 7 As shown, the heat conducting device 3 is arranged on a part of the side wall of the inner tube 2 near the bottom, and an openable and sealable exhaust port and liquid inlet are arranged at positions corresponding to the heat conducting device 3 of the inner tube 2. More specifically, an exhaust portion 34 of the heat conducting device 3 is inserted into the exhaust port of the inner tube 2, and a one-way liquid inlet valve 31 is inserted into the liquid inlet.

[0096] Therefore, in this embodiment, the clothes are in direct contact with the heat conducting device 3, so that the heat conducting device 3 has a higher drying efficiency for the clothes.

[0097] Embodiment 4

[0098] like Figure 1 , 2 As shown in , 3, 4, 5 and 8, this embodiment provides a clothing processing device. The difference between this embodiment and embodiment 1, embodiment 2 and embodiment 3 is that the heat conducting device 3 is arranged on the inner side of the side wall of the inner drum 2 and circumferentially surrounds the side wall to form a cavity for accommodating a heat conducting medium.

[0099] The electromagnetic heating device 32 and the heat-conducting device 3 therein circumferentially surround the inner wall of the inner drum 2 so that the heat-conducting device 3 can directly and more evenly contact the clothes.

[0100] Specifically, Figure 8 As shown, the inner tube 2 is provided with an openable and sealable exhaust port and liquid inlet at positions corresponding to the heat conducting device 3. More specifically, the exhaust port of the inner tube 2 is inserted with an exhaust portion 34 of the heat conducting device 3, and the liquid inlet is inserted with a one-way liquid inlet valve 31.

[0101] More specifically, Figure 8 As shown, the exhaust port of the chamber and the exhaust portion 34 disposed therein include two groups, which are respectively disposed on opposite sides of the side wall of the inner tube 2.

[0102] Therefore, in this embodiment, the inner drum 2 and the clothes therein are heated more evenly, further improving the drying efficiency of the clothes processing device.

[0103] Embodiment 5

[0104] This embodiment provides a clothes processing device, and the difference between this embodiment and the first to fourth embodiments is that the heat conducting device 3 surrounds part of the bottom of the inner drum 2 to form the cavity. It is more convenient to install the heat conducting device 3 inside or outside the inner drum 2, and the heat conducting device 3 dries the clothes more evenly.

[0105] Embodiment 6

[0106] like Figures 1 to 8 As shown, this embodiment provides a control method for a clothes processing device, and the control method of this embodiment is used to control the clothes processing devices described in Embodiments 1 to 5, including:

[0107] Before the drying starts, the water is preheated to the preheating temperature, and after detecting that the liquid inlet of the heat-conducting device 3 is aligned with the water inlet plug 33, the first motor 35 is powered to push the water inlet plug 33 to insert into the one-way liquid inlet valve 36, so that the liquid inlet part introduces a certain amount of heat-conducting medium into the heat-conducting device 3, and then stops the introduction, and the first motor 35 drives the water inlet plug 33 and the one-way liquid inlet valve 31 to separate, and the electromagnetic heating device 32 is powered to generate an alternating magnetic field;

[0108] After the heat conducting device 3 reaches the set temperature, the vacuum device 74 is turned on to extract the water vapor and air in the inner drum 2, lowering the boiling point of the water inside the inner drum 2, so that the water on the surface of the clothes evaporates and the water inside the clothes penetrates and evaporates to the surface, and the second motor 71 is turned on to drive the transmission shaft 62 and drive the inner drum 2 to rotate, so that the clothes inside are continuously rotated and beaten, and are evenly heated, thereby accelerating drying;

[0109] After the drying operation time is over, the vacuuming device 74 is stopped, and the vacuuming device 74 and the electromagnetic heating device 32 are turned off.
