Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of clothes treatment equipment, in particular, relates to a clothes treatment equipment and a control method thereof. BACKGROUND

[0002] The clothes treatment equipment with clothes drying function in the prior art generally sets a drying air duct communicating with the clothes treatment drum, and sets a heating device and a fan in the drying air duct. The air is driven to circulate between the clothes treatment drum and the drying air duct, and the air is heated when passing through the drying air duct, so as to continuously take out the moisture in the clothes, and realize the drying process. However, the above scheme is easy to bring the lint falling from the clothes into the drying air duct, and then the lint may be attached to the surface of the heating device in the drying air duct. In the process of continuous heating of the heating device, the residual lint may be burned due to the high temperature, which causes the dried clothes to have an odor, and even causes a fire hazard.

[0003] In view of the above problems, a non-contact heating method is currently proposed to realize the drying of clothes. For example, a clothes treatment device is disclosed in Chinese Patent No. 201710646637.1, which comprises: a drum composed of at least a part of metal, rotatably arranged around a rotating shaft; a washing tub for accommodating the drum; an induction part arranged in the washing tub for generating a magnetic field to heat the drum; and an air flow path part composed of a first air duct, a second air duct and a fan, the first air duct serving as a passage for discharging air outside the washing tub, the second air duct serving as a passage for flowing air into the inside of the washing tub, and the fan generating air flow, wherein the air flowing into the inside of the washing tub from the second air duct flows into the inside of the drum through the through hole arranged on the circumferential surface of the drum after passing through the drum opening part arranged in front of the drum, and then is discharged to the first air duct.

[0004] In the above scheme, the circulating air does not directly pass through the induction part for heating, which avoids the problem of burning of lint in the prior art, but the air duct and the fan located outside the drum still need to be arranged in the clothes treatment device, which occupies the internal space of the clothes treatment device. At the same time, the induction part only heats the drum wall, and the environment temperature of the clothes close to the wall is higher, and when the amount of clothes is large, the drying speed of different clothes may be inconsistent. On the other hand, the clothes directly contact the drum wall which is heated, and if the heating temperature is not stable, the clothes may be damaged due to the high temperature.

[0005] Therefore, the present application is proposed. SUMMARY

[0006] The technical problem solved by the present application is to overcome the deficiencies of the prior art, and provide a laundry treatment apparatus with an air agitation mechanism arranged in a laundry treatment drum, and a control method thereof, the air agitation mechanism being capable of generating an air flow in the drum by rotating, thereby causing the air in the drum to flow, bringing the heated air in the drum to be uniformly dispersed, and further causing the temperature distribution in the drum to be uniform, which is conducive to improving the drying effect of the laundry.

[0020] Preferably, the second rib is spaced apart from the outer periphery of the air agitation mechanism at one end close to the outer periphery of the air agitation mechanism.

[0021] More preferably, one end of the first protruding rib is flush with the outer periphery of the air agitation mechanism.

[0022] Further, the second protruding rib extends from the surface of the air agitation mechanism towards the direction away from the center of the air agitation mechanism at a certain angle with respect to the central end surface of the one end of the second protruding rib close to the center of the air agitation mechanism;

[0023] Preferably, the outer peripheral end surface of the other end of the second protruding rib extends from the surface of the air agitation mechanism towards the direction close to the center of the air agitation mechanism at a certain angle;

[0024] More preferably, the angle of the central end surface is larger than the angle of the outer peripheral end surface.

[0025] Further, the second protruding rib has a certain width along the circumferential direction of the air agitation mechanism, and the width of the second protruding rib gradually decreases towards the direction away from the surface of the air agitation mechanism;

[0026] Preferably, the two opposite side surfaces of the second protruding rib extend symmetrically towards each other along the direction away from the surface of the air agitation mechanism, and the distance between the two side surfaces gradually decreases along the direction away from the surface of the air agitation mechanism.

[0027] Further, the air agitation mechanism is a press-shaped structure of the drum body of the laundry treatment drum from outside to inside.

[0028] Further, the air agitation mechanism is arranged at the bottom of the laundry treatment drum, and the heating device is arranged outside the bottom of the laundry treatment drum, and the air inside the drum is heated by heating the bottom of the drum.

[0029] Preferably, the bottom of the drum is at least partially made of a metal material capable of generating eddy current in an alternating magnetic field, and the heating device comprises an electromagnetic heating module, which generates an outwardly radiating alternating magnetic field to heat the bottom of the drum.

[0030] Another object of the present application is to provide a control method of the above-mentioned laundry treatment device, wherein the heating device is turned on to heat, and the rotation of the air agitation mechanism is controlled to generate air flow inside the laundry treatment drum, and the temperature of the air inside the laundry treatment drum is uniformly distributed.

[0031] Further, the air agitation mechanism is connected to the laundry treatment drum, and when the heating device is turned on, the rotation of the laundry treatment drum is controlled to drive the air agitation mechanism to rotate synchronously, so as to generate air flow inside the laundry treatment drum.

[0032] Preferably, the air agitation mechanism is arranged at the bottom of the laundry treatment drum, and the heating device is arranged outside the bottom of the laundry treatment drum, and when the heating device is turned on, the rotation of the laundry treatment drum is controlled to drive the air agitation mechanism to rotate continuously, so as to make the air heated close to the bottom of the drum flow towards the opening of the drum.

[0033] Compared with the prior art, the present application has the following beneficial effects.

[0048] Embodiment 1

[0049] The present embodiment provides a laundry treating apparatus and a control method thereof.

[0050] The laundry treating apparatus of the present embodiment comprises:

[0051] A laundry treating cylinder for providing a laundry containing space;

[0052] A heating device for heating air inside the laundry treating cylinder. ​

[0053] The air agitation mechanism is protruded into the interior of the clothes treatment drum, and rotation of the air agitation mechanism generates air flow in the interior of the clothes treatment drum to uniformly distribute the temperature of the air in the interior of the clothes treatment drum.

[0054] In the above scheme, the air agitation mechanism is protruded into the interior of the clothes treatment drum, and rotation of the air agitation mechanism generates air flow in the interior of the clothes treatment drum to strengthen the air flow in the drum, which is conducive to uniform distribution of the heated air in the clothes treatment drum to the various regions in the interior of the clothes treatment drum, thereby improving the uniformity of the temperature distribution in the drum and improving the drying effect of the clothes. At the same time, the air is circulated in the interior of the clothes treatment drum by the air agitation mechanism, and the space required for setting the air duct and the fan outside the clothes treatment drum is saved.

[0055] On the other hand, since the heat generated by the heating device can only be transferred to the air within a certain range around the heating device, the air flow in the drum is strengthened by the air agitation mechanism, which is also conducive to the heated air flowing to other regions and also helps to drive the air with a lower temperature in other regions to the range of the heating device. This also helps to quickly heat the air in the drum under the action of the heating device, improves the air temperature rising rate in the drum, and further improves the drying efficiency of the clothes.

[0056] The control method of the clothes treatment device in the embodiment includes: the heating device is turned on to heat, and the air agitation mechanism is controlled to rotate to generate air flow in the interior of the clothes treatment drum to uniformly distribute the temperature of the air in the interior of the clothes treatment drum.

[0057] During the heating process, the air agitation mechanism is controlled to rotate to generate air flow in the drum, and the air with a higher temperature after being heated is sent to other regions in the drum to achieve the effect of uniform temperature distribution in the drum.

[0058] In a further scheme of the embodiment, the air agitation mechanism is connected with the clothes treatment drum. When the heating device is turned on, the clothes treatment drum is controlled to rotate to drive the air agitation mechanism to rotate synchronously to generate air flow in the interior of the clothes treatment drum.

[0059] In the above scheme, the clothes treatment drum needs to be controlled to rotate to turn over the clothes during the clothes drying process. The air agitation mechanism is connected with the clothes treatment drum, and the air agitation mechanism is driven to rotate synchronously by controlling the rotation of the clothes treatment drum, without the need to set a separate driving device for the air agitation mechanism, which is simple in structure and easy to control.

[0060] In the preferred embodiment of the present application, the air agitation mechanism is a profiled structure of the drum body of the laundry treating drum from outside to inside. In this way, the protruding air agitation mechanism can be directly formed on the drum body by a stamping process or other similar processes during the manufacturing process of the laundry treating drum, without the need to add additional assembly steps to install the air agitation mechanism on the drum body, thereby saving manufacturing procedures.

[0061] In the present application, the air agitation mechanism is provided with a plurality of ribs protruding towards the inside of the laundry treating drum. The rib structure agitates the air in the drum during rotation, which can significantly enhance the effect of air flow.

[0062] As shown in Figures 1 to 3 In the specific embodiment of the present application, the rib is a profiled structure of the drum bottom 100 of the laundry treating drum from outside to inside, and the drum bottom 100 itself is the air agitation mechanism.

[0063] Specifically, the rib includes:

[0064] The first rib 110 extends from the outer periphery to the inside of the drum bottom 100 and is arranged in a plurality along the circumference of the drum bottom 100.

[0065] The second rib 120 is arranged between two adjacent first ribs 110.

[0066] Preferably, the first rib 110 extends along the radial direction of the drum bottom 100, and the second rib 120 is arranged between any two adjacent first ribs 110.

[0067] In a further embodiment of the present application, the second rib 120 extends along the radial direction of the drum bottom 100 and is arranged on the angle bisector of the included angle formed between two adjacent first ribs 110.

[0068] Preferably, the first rib 110 extends from the outer periphery of the drum bottom 100 to the center of the drum bottom 100, and the extension ends of a plurality of first ribs 110 are connected. The second rib 120 is spaced apart from the first rib 110 at one end close to the center of the drum bottom 100.

[0069] In detail, the drum bottom 100 of the present application is provided with three first ribs 110, which are uniformly distributed along the circumference of the drum bottom 100, and the included angle between two adjacent first ribs 110 is 120°. Three second ribs 120 are also arranged on the angle bisectors of the included angles, i.e., the included angle between the first rib 110 and the second rib 120 is 60°.

[0070] The first protruding ribs 110 and the second protruding ribs 120 are formed by the profiling structure of the bottom 100 itself, and the recessed groove structure is formed in the area corresponding to the first protruding ribs 110 and the second protruding ribs 120 outside the bottom 100. In particular, the recessed groove structure formed by each first protruding rib 110 is communicated at the center of the bottom 100, thereby forming a mounting space for the tripod, and the tripod is connected with the driving shaft to realize the rotation of the clothes processing drum driven by the driving device, and the structure is more stable.

[0071] In the above scheme, the first protruding ribs 110 and the second protruding ribs 120 rotate together with the clothes processing drum, and during the rotation of the clothes processing drum, the first protruding ribs 110 and the second protruding ribs 120 cooperate to form an effect similar to that of the blades of an axial flow fan, causing forced convection of air in the drum, accelerating the flow speed of air in the drum, and the effect of strengthening air flow is better.

[0072] In a further scheme of the embodiment, the central end face 121 of the second protruding rib 120 close to one end of the center of the bottom 100 extends from the surface of the bottom 100 to the direction away from the center of the bottom 100.

[0073] Preferably, the outer peripheral end face 122 of the other end of the second protruding rib 120 extends from the surface of the bottom 100 to the direction close to the center of the bottom 100.

[0074] More preferably, the inclination degree of the central end face 121 is greater than the inclination degree of the outer peripheral end face 122.

[0075] In the above scheme, the central end face 121 of the second protruding rib 120 is provided as an inclined surface, so that the second protruding rib 120 gradually protrudes from the position close to the center of the bottom 100 to the outer peripheral direction, and the stirring degree of air gradually increases, which can have a more significant effect of strengthening air flow. The outer peripheral end face 122 of the second protruding rib 120 is also provided as an inclined surface, but the inclination degree is smaller, which on the one hand ensures the stirring degree of air of the second protruding rib 120 close to the outer periphery of the bottom 100, and on the other hand can leave a certain gap between the outer end of the second protruding rib 120 and the drum wall of the clothes processing drum, thereby ensuring the formation of air convection.

[0076] In the embodiment, there is a certain gap between the one end of the second protruding rib 120 close to the outer periphery of the bottom 100 and the outer periphery of the bottom 100, which further ensures that there is sufficient gap between the outer end of the second protruding rib 120 and the drum wall.

[0077] Further, one end of the first protruding rib 110 is flush with the outer periphery of the bottom 100, and the tripod mounted outside the bottom 100 can be fixed with the bottom 100 through the outer end face 111 of the first protruding rib 110, and the mounting mode is stable and firm.

[0078] In the embodiment, the second protruding ribs 120 have a certain width along the circumference of the drum bottom 100, and the width of the second protruding ribs 120 gradually narrows away from the surface of the drum bottom 100.

[0079] Preferably, the two second side surfaces 123 of the second protruding ribs 120 symmetrically extend towards each other away from the surface of the drum bottom 100, and the distance between the two second side surfaces 123 gradually decreases away from the surface of the drum bottom 100.

[0080] In the above scheme, the cross section of the second protruding ribs 120 is approximately isosceles trapezoidal, which is closer to the structure of a fan blade, and is conducive to the flow of air along the surface of the second side surface 123, thereby further improving the effect of strengthening air convection, increasing the air flow speed, and thus increasing the air temperature rise rate to improve the drying efficiency of the clothes.

[0081] In the embodiment, the two first side surfaces 112 of the first protruding ribs 110 are also inclined surfaces, and symmetrically extend towards each other away from the surface of the drum bottom 100, so that the width of the first protruding ribs 110 gradually narrows away from the surface of the drum bottom 100.

[0082] Specifically, the width of the first protruding ribs 110 on the surface of the drum bottom 100 is greater than the width of the second protruding ribs 120 on the surface of the drum bottom 100, and the width of the first top surface 113 of the first protruding ribs 110 away from the surface of the drum bottom 100 is greater than the width of the second top surface 124 of the second protruding ribs 120 away from the surface of the drum bottom 100.

[0083] In a further scheme of the embodiment, the protruding height of the second protruding ribs 120 from the surface of the drum bottom 100 is different from the protruding height of the first protruding ribs 110 from the surface of the drum bottom 100. Preferably, the protruding height of the second protruding ribs 120 is greater.

[0084] In the above scheme, with the rotation of the clothes treatment drum, the second protruding ribs 120 play a dominant role in stirring air, and the first protruding ribs 110 are mainly used to form the mounting space of the tripod, but the inner side surface of the first protruding ribs 110 protruding from the drum bottom 100 can also assist the second protruding ribs 120 in stirring air during the rotation of the clothes treatment drum. Through the cooperation of the second protruding ribs 120 and the first protruding ribs 110, the air in the drum is forced to circulate during the rotation of the clothes treatment drum, and the circulating flow of the air in the drum can continuously carry out the moisture in the clothes, thereby achieving the drying of the clothes.

[0085] In the clothes treatment device provided by the embodiment, the heating device is specifically arranged outside the drum bottom 100 of the clothes treatment drum, and the air in the clothes treatment drum is heated by heating the drum bottom 100.

[0086] Correspondingly, the control method of the clothes treatment device comprises: when the heating device is turned on, controlling the clothes treatment drum to continuously rotate, and driving the air stirring mechanism to continuously rotate, so that the air near the bottom 100 of the drum flows to the direction of the drum opening.

[0087] In the above scheme, the heating device is arranged outside the clothes treatment drum and does not rotate with the clothes treatment drum. The installation of the heating device and the connection of the power supply line are more convenient.

[0088] The heating device heats the bottom 100 of the drum to heat the air in the drum. The temperature of the bottom 100 is relatively high. On the one hand, the clothes in the drum are mainly in contact with the drum wall, and less in contact with the bottom 100 of the drum, so that damage to the clothes caused by high temperature can be avoided as much as possible.

[0089] On the other hand, the air near the bottom 100 of the drum can be heated after the bottom 100 of the drum is heated. The air stirring mechanism on the bottom 100 of the drum, i.e. the first protruding rib 110 and the second protruding rib 120, can rotate with the clothes treatment drum, so that the air near the bottom 100 of the drum flows to the direction of the drum opening, thereby driving the heat to disperse to the direction of the drum opening. At the same time, the air near the drum opening with a lower temperature flows to the bottom 100 of the drum under the action of convection, and is then heated by the bottom 100 of the drum. Through the cooperation of the heating device and the air stirring mechanism, the uniform distribution of the temperature in the drum is achieved, which is also conducive to improving the heating speed and thereby improving the drying efficiency of the clothes.

[0090] By driving the air in the drum to circulate through the bottom 100 of the drum, and heating the air in the drum, an effect similar to that of an oven can be achieved. The higher the speed of the clothes treatment drum, the higher the heating efficiency, and the better the drying effect of the clothes.

[0091] The heating device can be an electric heating device, such as a heating wire. However, since the electric heating device does not rotate with the clothes treatment drum, it is not in direct contact with the bottom 100 of the clothes treatment drum, and generally needs to have a certain gap with the bottom 100 of the drum. The existence of the gap will cause a certain degree of loss of the heat generated by the electric heating device, which cannot be completely transmitted to the bottom 100 of the drum, thereby reducing the heating efficiency of the electric heating device.

[0092] In the preferred scheme of the present embodiment, the bottom 100 of the drum is at least partially made of a metal material capable of generating eddy current in an alternating magnetic field, and the heating device comprises an electromagnetic heating module. The electromagnetic heating module generates an outwardly radiating alternating magnetic field to heat the bottom 100 of the drum.

[0093] The cylinder bottom 100 in the embodiment is integrally formed and is made of a metal material that can be excited by an alternating magnetic field to generate eddy current. An electromagnetic heating module is used as a heating device, and the cylinder bottom 100 is heated by the radiation of a magnetic field to the cylinder bottom 100, thereby achieving the purpose of heating the air in the cylinder. The electromagnetic heating module can realize efficient non-contact heating of the cylinder bottom 100, reducing heat loss, thereby achieving the purpose of energy saving while ensuring higher heating efficiency.

[0094] In the embodiment, the first and second protruding ribs 110 and 120 integrally arranged on the cylinder bottom 100 can strengthen the air flow in the laundry treatment cylinder during the rotation of the laundry treatment cylinder, and cooperate with the heating device to uniformly heat the air in the laundry treatment cylinder, thereby improving the uniformity of the temperature distribution in the cylinder and improving the drying effect of the laundry.

[0095] Embodiment Two

[0096] The difference between the embodiment and the above-mentioned embodiment one is that the air agitation mechanism is a separate part rotatably installed in the interior of the laundry treatment cylinder.

[0097] Specifically, the air agitation mechanism has a disc structure coaxially arranged with the cylinder bottom of the laundry treatment cylinder, and the first and second protruding ribs are arranged on the surface of the side of the disc structure facing away from the cylinder bottom, for generating air flow in the laundry treatment cylinder during the rotation of the disc structure.

[0098] In the embodiment, the specific structure of the first and second protruding ribs is basically the same as that in the first embodiment. The higher the rotation speed of the air agitation mechanism, the more significant the effect of strengthening the air flow, and the better the drying effect of the laundry. However, the laundry treatment cylinder is used to hold the laundry to be dried, and is limited by the weight of the laundry, so the rotation speed of the laundry treatment cylinder cannot be increased unlimitedly. By arranging the air agitation mechanism as a separate part, the rotation speed of the air agitation mechanism can be controlled independently, thereby increasing the upper limit of the rotation speed of the air agitation mechanism and further improving the drying effect of the laundry.

[0099] Further, in the embodiment, the air agitation mechanism can be made of a metal material, and an electromagnetic heating module as a heating device radiates an alternating magnetic field to the air agitation mechanism to heat it, thereby heating the air in the cylinder.

[0100] Embodiment Three

[0101] The difference between the embodiment and the above-mentioned embodiment one is that the air agitation mechanism is arranged on the cylinder wall of the laundry treatment cylinder.

[0102] Specifically, the air agitation mechanism includes a plurality of protruding ribs arranged on the cylinder wall of the laundry treatment cylinder and protruding into the interior of the laundry treatment cylinder.

[0103] Preferably, the convex ribs are a compression structure of the laundry treating drum from outside to inside, which are formed directly on the drum wall during the forming process of the drum wall, saving the assembly process.

[0104] In detail, the convex ribs are arranged along the circumferential direction of the drum wall and extend from the drum bottom to the drum opening.

[0105] In the embodiment, the convex ribs arranged on the drum wall serve as the air stirring mechanism, which stirs the air along the circumferential direction with the rotation of the laundry treating drum, drives the air in the drum to flow along the circumferential direction, and makes the heat in the drum evenly distributed, thereby improving the drying efficiency of the laundry and the user experience.

[0106] Embodiment Four

[0107] The difference between the embodiment and the above-mentioned embodiment one is that the air stirring mechanism is arranged inside the laundry treating drum and protrudes into the interior of the laundry treating drum.

[0108] In one scheme of the embodiment, the part of the laundry treating drum located at the outer periphery of the drum opening is provided with a protruding structure that protrudes into the interior of the laundry treating drum, and the protruding structure is preferably a compression structure of the laundry treating drum from outside to inside.

[0109] The protruding structure rotates synchronously with the laundry treating drum, stirs the air in the drum opening region, and thus generates air flow in the drum. The air flowing in the drum cooperates with the heating device, so that the temperature in the drum is more evenly distributed, thereby improving the drying effect of the laundry.

[0110] In another scheme of the embodiment, the drum opening of the laundry treating drum is provided with an openable / closable drum door, and the air stirring mechanism is arranged on the inner side of the drum door and protrudes into the interior of the laundry treating drum.

[0111] Specifically, the drum door is provided with convex ribs as the air stirring mechanism. Preferably, the convex ribs are a compression structure of the drum door from outside to inside.

[0112] In the above scheme, the specific structure of the convex ribs is similar to that in the first embodiment, including the first convex ribs and the second convex ribs extending along the radial direction of the drum door, which can effectively stir the air in the drum, thereby generating air flow from the drum opening to the drum bottom, and helping the air temperature in the drum to be evenly distributed during the heating process of the heating device.

[0113] Further, the heating device in the embodiment is installed outside the barrel mouth of the clothes treatment barrel, preferably opposite to the barrel door.
