Description

Technical Field

[0001] The utility model relates to the field of cleaning machines, in particular to a heat dissipation structure and a fabric cleaning machine. Background Art

[0002] Because cleaning products, especially fabric cleaning machines, require power components in the suction drive mechanism to be waterproof and noise-reducing, the power components are usually wrapped and sealed inside the entire machine. This causes the power components to rise in temperature very high, affecting their lifespan and making it difficult to pass safety regulations for temperature rise testing.

[0003] The Chinese invention patent document with the authorization publication number CN201624600U discloses an air duct structure for a vacuum cleaner, including a dust collection duct for vacuuming operations and a cooling duct for heat exchange of the motor in the vacuum cleaner, wherein the dust collection duct and the cooling duct are two independent air passages. The air duct structure of the vacuum cleaner separates the dust collection duct from the cooling duct so that the two ducts do not interfere with each other. On the one hand, it ensures that the vacuum cleaner has a good suction effect, and on the other hand, it also achieves good heat dissipation of the motor. However, since both the cold air inlet and the hot air outlet use the same cooling duct, the cold air and the hot air affect each other, resulting in a less than ideal heat dissipation effect. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the utility model provides a heat dissipation structure and a fabric cleaning machine.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model provides a heat dissipation structure, comprising:

[0007] a power mechanism, the power mechanism having a cold air inlet and a hot air outlet, the cold air inlet being used to allow external cold air to enter the power mechanism, and the hot air outlet being used to discharge hot air generated by heat exchange between the external cold air and the heat generated by the operation of the power mechanism to the outside of the power mechanism; and

[0008] The body has an inner cavity, an air inlet duct and an air outlet duct, the inner cavity accommodates the power mechanism, the air inlet end of the air inlet duct is used to communicate with the outside world, the air outlet end of the air inlet duct is connected to the cold air inlet, the air inlet end of the air outlet duct is connected to the hot air outlet, and the air outlet end of the air outlet duct is used to communicate with the outside world, and the air inlet duct and the air outlet duct are respectively placed on both sides of the inner cavity.

[0009] The heat dissipation structure of the present invention includes a power mechanism and a machine body, wherein the power mechanism has a cold air inlet and a hot air outlet, the cold air inlet can allow external cold air to enter the power mechanism, and the hot air outlet can guide the hot air formed by the external cold air and the heat generated by the operation of the power mechanism to the outside of the power mechanism, the machine body has an inner cavity, an air inlet duct and an air outlet duct, the inner cavity accommodates the power mechanism, the air inlet end of the air inlet duct can be communicated with the outside, the air outlet end of the air inlet duct can be communicated with the cold air inlet, so that the external cold air can enter the power mechanism through the air inlet duct, the air inlet end of the air outlet duct can be communicated with the hot air outlet, and the air outlet end of the air outlet duct can be communicated with the outside, so that the hot air formed after heat exchange with the power mechanism can be guided to the outside through the air outlet duct, thereby realizing heat dissipation of the power mechanism. In the invention, since the air inlet duct for the cold air and the air outlet duct for the hot air are independently arranged and the air inlet duct and the air outlet duct are respectively placed on both sides of the inner cavity, the air inlet duct and the air outlet duct do not interfere with each other, and the cold air and hot air can be isolated, and the cold air and the hot air will not be mixed with each other, thereby ensuring that the cold air can dissipate the heat of the power mechanism more efficiently, that is, it can efficiently discharge the heat generated when the power mechanism is working, improve the heat dissipation effect, enable the power mechanism to pass the safety test requirements, and at the same time, avoid continuous high temperature that reduces the service life of the power mechanism. In addition, since the air inlet duct and the air outlet duct are structures formed on the body, there is no need to add additional heat dissipation duct structural parts. The structure is simple and practical, and the cost is low, which is conducive to the promotion and application of the heat dissipation structure and electrical appliances such as fabric cleaning machines that use the heat dissipation structure.

[0010] In one embodiment, the air inlet duct and the air outlet duct are spaced apart along the first direction of the body, so that the distance between the air inlet end of the air inlet duct and the air outlet end of the air outlet duct is far enough, thereby effectively isolating the air inlet duct and the air outlet duct, effectively avoiding the mutual mixing of cold air and hot air, and being more conducive to heat dissipation.

[0011] In one embodiment, the hot air outlet and the outlet end of the air outlet duct are spaced apart along the first direction of the body, that is, the hot air outlet and the outlet end of the air outlet duct are both located in the same direction of the body, which can effectively shorten the distance between the hot air outlet and the outlet end of the air outlet duct, thereby shortening the length of the air outlet duct, so that the hot air can be more smoothly discharged to the outside of the body, which is conducive to further improving the heat dissipation efficiency.

[0012] In one embodiment, the hot air outlet is aligned with the outlet end of the air outlet duct, or the hot air outlet is located below or above the outlet end of the air outlet duct. When the hot air outlet is aligned with the outlet end of the air outlet duct, the distance between the hot air outlet and the outlet end of the air outlet duct is the shortest, which means the length of the air outlet duct can be minimized, allowing the hot air to be more smoothly discharged to the outside of the machine, resulting in higher heat dissipation efficiency. When the hot air outlet is located below or above the outlet end of the air outlet duct, the distance between the hot air outlet and the outlet end of the air outlet duct can also be effectively shortened, thereby shortening the length of the air outlet duct and allowing the hot air to be more smoothly discharged to the outside of the machine, which helps further improve heat dissipation efficiency.

[0013] In one embodiment, the cold air inlet and the air inlet end of the air inlet duct are spaced apart along the first direction of the body, that is, the cold air inlet and the air inlet end of the air inlet duct are both located in the same direction of the body, which can effectively shorten the distance between the cold air inlet and the air inlet end of the air inlet duct, thereby shortening the length of the air inlet duct, so that the cold air can be more smoothly introduced into the interior of the power mechanism, which is conducive to further improving the heat dissipation efficiency.

[0014] In one embodiment, the cold air inlet is aligned with the air inlet end of the air inlet duct, or the cold air inlet is located below or above the air inlet end of the air inlet duct, so as to effectively shorten the length of the air inlet duct and enable the cold air to be more smoothly introduced into the interior of the power mechanism, thereby further improving the heat dissipation efficiency.

[0015] In one embodiment, the housing further comprises an installation cavity, located between the air inlet and outlet ducts, for accommodating electrical components. This allows the installation cavity to effectively isolate the air inlet and outlet ducts, preventing cold air and hot air from mixing, while also improving the space utilization between the air inlet and outlet ducts. This improves the space utilization of the installation cavity and makes the overall heat dissipation structure more compact.

[0016] In one embodiment, the power mechanism comprises:

[0017] A cover body is provided in the inner cavity, and has the cold air inlet, the hot air outlet and an accommodating cavity;

[0018] A power component is disposed in the accommodating cavity, the power component is provided with an output shaft, and a portion of the output shaft extends outside the accommodating cavity;

[0019] an isolation seal, the isolation seal being interposed between the power component and the inner wall of the accommodating chamber to separate the accommodating chamber into an upper chamber section and a lower chamber section, the upper chamber section being connected to the cold air inlet and forming an airflow channel with the power component, and the lower chamber section being connected to the hot air outlet; and

[0020] A heat dissipation impeller is sleeved on the output shaft, the heat dissipation impeller is located in the lower chamber section, and can rotate with the output shaft. The heat dissipation impeller is used to guide the hot air in the air flow channel to the hot air outlet. In this way, when the power component is working, the output shaft rotates to drive the heat dissipation impeller to rotate. The heat dissipation impeller rotates to draw external cold air into the cold air inlet through the air inlet duct. The cold air enters the air flow channel through the cold air inlet and exchanges heat with the heat generated by the power component during operation, thereby forming hot air. Under the guidance of the heat dissipation impeller, the hot air passes through the lower chamber section, the hot air outlet, and the air outlet duct in sequence and is discharged to the outside. In particular, an isolation seal can be used to isolate the cold air in the air flow channel from the hot air in the lower chamber section, effectively limiting the hot air in the lower chamber section from flowing into the air flow channel, that is, effectively preventing the cold air and hot air from mixing with each other, so that the heat generated by the power component during operation can only be discharged through the hot air outlet and will not mix with the air flow channel area, which is conducive to further improving the heat dissipation effect.

[0021] In one embodiment, the isolation seal is provided with a first sealing portion and a second sealing portion, wherein the first sealing portion is sleeved on the outer peripheral wall of the power component, the first sealing portion is arranged around the power component, the first end of the second sealing portion is connected to the first sealing portion, the second end of the second sealing portion is separated from the power component, the second sealing portion is arranged around the first sealing portion and is inclined outward and downward relative to the first sealing portion, and the second sealing portion abuts against the inner wall of the accommodating cavity. Particularly, since the first end of the second sealing portion is connected to the first sealing portion and the second end of the second sealing portion is separated from the power component, the second sealing portion can move relative to the first sealing portion. During installation, the first sealing portion is first pre-installed on the outer peripheral wall of the power component, and then the power component is installed into the cover until the second sealing portion abuts against the inner wall of the accommodating cavity. The installation operation is simple and can greatly improve the installation efficiency. At the same time, the sealing reliability is high and can effectively isolate cold air and hot air.

[0022] In one embodiment, the body further comprises a dust suction cavity, a dust suction air inlet and a dust suction air outlet, the dust suction cavity is located on one end of the lower cavity section away from the upper cavity section, and the dust suction air inlet and the dust suction air outlet are both connected to the dust suction cavity;

[0023] The power mechanism further comprises:

[0024] A dust collection impeller is sleeved on the output shaft and can rotate with the output shaft. The dust collection impeller is used to create a negative pressure in the dust collection chamber. Thus, when the power component is operating, the output shaft rotates, driving the dust collection impeller to rotate. The rotation of the dust collection impeller creates a negative pressure in the dust collection chamber, sucking ambient air and dust into the body through the dust collection air inlet, separating dust and impurities through the filtration system, and then discharging clean air out of the body through the dust collection air outlet.

[0025] The utility model also provides a fabric cleaning machine, comprising the above-mentioned heat dissipation structure.

[0026] The fabric cleaning machine of the present invention adopts the above-mentioned heat dissipation structure, in which, the air inlet duct for the cold air and the air outlet duct for the hot air are independently arranged, and the air inlet duct and the air outlet duct are respectively placed on both sides of the inner cavity, so that the air inlet duct and the air outlet duct do not interfere with each other, and the cold air and the hot air can be isolated, and the cold air and the hot air will not be mixed with each other, thereby ensuring that the cold air can dissipate the heat of the power mechanism more efficiently, that is, it can efficiently discharge the heat generated when the power mechanism is working, improve the heat dissipation effect, and enable the power mechanism to pass the requirements of safety tests. At the same time, it avoids continuous high temperature that reduces the service life of the power mechanism. In addition, since the air inlet duct and the air outlet duct are structures formed on the body, there is no need to add additional heat dissipation duct structural parts. The structure is simple and practical, and the cost is low, which is conducive to the promotion and application of heat dissipation structures and electrical appliances such as fabric cleaning machines that use the heat dissipation structure.

The second sealing portion 132 is arranged around the first sealing portion 131 and is inclined outward and downward relative to the first sealing portion 131. The second sealing portion 132 abuts against the inner wall of the accommodating cavity 113. Among them, since the first end of the second sealing part 132 is connected to the first sealing part 131 and the second end of the second sealing part 132 is separated from the power component 12, the second sealing part 132 can move relative to the first sealing part 131.
