Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a heat exchange device and a clothing treatment device. Background Technology

[0002] As people's living standards improve, clothes dryers have gradually become a common household appliance. The working principle of a clothes dryer is to use a heating device to heat relatively dry air, enabling it to carry moisture. The heated, dry air is then sent into the drum by a fan, coming into contact with the wet clothes and transferring heat to them. This causes the moisture in the clothes to evaporate as water vapor. The dry air absorbs the water vapor and becomes medium-to-high temperature saturated humid air. This saturated humid air is then carried away from the clothes by the fan, achieving the drying effect.

[0003] However, traditional clothes dryers generally suffer from low airflow during the drying process, which directly reduces drying efficiency. Prolonged drying not only consumes more energy but also causes considerable inconvenience for users. To address this problem, related technologies have been continuously explored and improved. For example, patent CN222100435U proposes installing dual impellers in the dryer's air duct and driving each impeller independently to increase airflow and thus improve drying efficiency. However, this solution has significant drawbacks. On the one hand, the dual impeller and independent drive design greatly increases the structural complexity of the dryer, making manufacturing and assembly more cumbersome, increasing production costs, and placing higher demands on manufacturing processes, hindering large-scale production and promotion. On the other hand, it also hinders the miniaturization of the dryer, occupying a significant amount of user space. Therefore, there is an urgent need for an innovative technological solution that can effectively improve the airflow and drying efficiency of a clothes dryer without significantly increasing structural complexity.

[0033] Embodiment 1

[0034] As Figures 1-4 shown, the present application discloses a heat exchange device, comprising:

[0035] A heating assembly 4 is used for heating air;

[0036] A fan assembly 5 comprises a supply air shell 502, a first fan 501 is arranged in the supply air shell 502, a air inlet part 101 is arranged on the lower side of the first fan 501, and the air inlet part 101 is communicated with the heating assembly 4;

[0037] The air supply shell 502 is provided with a mounting portion 503, a first gas flow path 504 is formed between the air supply shell 502 and the mounting portion 503, the inside of the mounting portion 503 forms a second gas flow path 505, the left end of the second gas flow path 505 is an air outlet 102, and the right end is an air inlet 103; the air outlet 102 is used for sending air flow into the air supply duct 3, and the air inlet 103 is used for introducing external air.

[0038] The mounting portion 503 is provided with a communication port 507, the first gas flow path 504 and the second gas flow path 505 are communicated through the communication port 507, the air flow sent by the first fan 501 enters the second gas flow path 505 through the first gas flow path 504 and the communication port 507, and drives the air flow flowing into the air inlet 103 to the air outlet 102.

[0039] The heat exchange device provided in the application, when the air flow sent by the first fan 501 enters the second gas flow path 505 through the first gas flow path 504 and the communication port 507, an entraining effect is generated, when the high-speed air flow flows into the second gas flow path 505 from the communication port 507, a low-pressure area is formed near the air inlet 103, thereby driving external air to flow into the air inlet 103, the entraining effect enables more air to enter the second gas flow path 505, and the air flow ejected from the communication port 507 is superimposed, so that the air supply amount is greatly improved, finally, the air supply amount is sent into the air supply duct 3 from the air outlet 102, and the air supply amount of the entire heat exchange device is significantly increased; for the clothes treatment device, the larger air volume can accelerate the contact between hot air and clothes and water evaporation, improve drying efficiency, and solve the problems of small air volume and low drying efficiency of the traditional clothes dryer.

[0040] The device only needs to cooperate the first fan 501 with the specially designed gas flow channel and the mounting portion 503 structure, so that the air supply amount is significantly improved, compared with the design of using double impellers or multiple fans to increase the air volume in the prior art, the structure of the design is simpler, the complexity of the equipment is reduced, the assembly difficulty and process requirement in the production and manufacturing process are reduced, the manufacturing cost of the heat exchange device is reduced, the workload and cost of later maintenance and repair are reduced, and the miniaturization design of the equipment is facilitated.

[0041] Preferably, the air supply duct 3 or the fan assembly 5 is provided with an overflow port for discharging excess air in the air supply duct 3, so as to ensure that the air pressure in the air supply duct 3 is in a set range.

[0042] As a preferred example of the present application, the first fan 501 comprises a fan blade and a high-speed motor, and the high-speed motor is used for driving the fan blade.

[0043] Specifically, the high-speed motor can drive the fan blade to a high speed, and the air volume of the fan is closely related to the speed, the higher the speed, the more air the fan pushes in a unit of time, therefore, using the high-speed motor to drive can significantly increase the air supply of the first fan 501, when the high-speed airflow is injected into the second gas flow path 505 from the communication port 507, a stronger injection effect is formed, more external air is introduced, the air supply is further increased, and the air conveying capacity of the entire heat exchange device is further enhanced, air is more effectively sent into the air supply duct 3, and the drying efficiency and heat exchange effect are improved.

[0044] The high-speed motor in the application has a speed greater than 5000r / min, and in the existing clothes dryer, the motor speed of the fan is generally 1700-2800r / min.

[0045] As a preferred example of the present application, the first gas flow path 504 includes a first flow part 5041 and a second flow part 5042 in communication, the second flow part 5042, the first flow part 5041 and the first fan 501 are sequentially arranged from top to bottom, the first fan 501 is an axial flow fan, the axial direction of the first fan 501 is perpendicular to the direction of the air outlet 102 of the second gas flow path 505, and the second flow part 5042 is concentrically arranged with the second gas flow path 505.

[0046] Specifically, the second flow part 5042 is annular, the airflow transported by the first fan 501 enters the second flow part 5042 after passing through the first flow part 5041, the airflow fills the second flow part 5042 to increase the pressure in the second flow part 5042, so that the airflow is injected into the second gas flow path 505 at high speed from the communication port 507, greatly enhancing the speed of the airflow in the second gas flow path 505, and further enhancing the air conveying capacity of the fan assembly 5.

[0047] As a preferred example of the present application, the right end of the second gas flow path 505 is in communication with the heating assembly 4, and the heating assembly 4 is provided with a first air vent for introducing external air.

[0048] Specifically, after the external fresh air enters the heating assembly 4, it can fully contact the heating element of the heating assembly 4 to achieve more efficient heating, and because the temperature of the fresh air is relatively low, the temperature difference between the heating element is large, according to the heat exchange principle, the larger temperature difference can speed up the heat transfer speed, so that the air is heated to the required temperature faster, and the heated hot air can be more effectively mixed with other airflows after entering the second gas flow path 505, improving the efficiency of the entire heat exchange process.

[0049] As a preferred example of the present application, the air inlet 103 is in communication with the outside world, for introducing external air.

[0050] Specifically, the air inlet 103 directly communicates with the outside world to introduce external air, which can improve the ejecting effect, guide more external fresh air into the second gas flow path 505, increase the air supply and drying efficiency of the entire heat exchange device, and simplify the structure of the heat exchange device, facilitating production and manufacturing.

[0051] On the other hand, during the drying of clothes, the participation of fresh air also helps to reduce the generation of odor, so that the dried clothes have a fresh smell, improving the user's experience.

[0052] As a preferred example of the present application, the mounting portion 503 is annular, and the communication openings 507 are arranged in an array on the mounting portion 503.

[0053] Specifically, the plurality of communication openings 507 arranged in an array can make the airflow in the first gas flow path 504 uniformly enter the second gas flow path 505. This design provides a structural basis for such uniform air intake, so that the airflow can flow into the second gas flow path 505 from various positions in the circumferential direction of the mounting portion 503 at the same time, ensuring the uniformity of airflow distribution in the second gas flow path 505. Uniform airflow distribution helps to reduce airflow turbulence in the second gas flow path 505. When the airflow uniformly flows from the plurality of communication openings 507, no local high-speed or low-speed airflow region is formed, reducing the possibility of airflow collision and interference, so that the airflow can flow more smoothly in the second gas flow path 505, reducing energy loss and improving the airflow conveying efficiency of the entire heat exchange device.

[0054] As a preferred example of the present application, the second flow portion 5042 is provided with a heating device 506, and the heating device 506 is used for heating the air flowing through the second flow portion 5042.

[0055] Specifically, the heating device 506 is arranged in the second flow portion 5042, which can make the heated air more uniformly diffuse in the first gas flow path 504. Since the air is heated during flow, the hot air is continuously mixed in the channel, avoiding local overheating or overcooling, thereby ensuring the uniformity of the hot air temperature entering the second gas flow path 505 and the air supply pipeline 3, and further improving the heat exchange effect.

[0056] On the other hand, the heating device 506 can be adjusted in real time according to the actual temperature in the heat exchange device, which helps to maintain the temperature balance of the whole system, and when the heating assembly 4 has temperature fluctuations or abnormalities, the heating device 506 can play a certain compensation role to ensure that the hot air temperature is stable, and ensure that the equipment is always in good working condition.

[0057] As a preferred example of the present application, the second flow part 5042 is provided with a guide vane, which can make the airflow in the second flow part 5042 flow spirally.

[0058] Specifically, when the airflow flows spirally, its movement path in the second flow part 5042 becomes longer, and since the second flow part 5042 is provided with a heating device 506, the longer movement path means that the air has more contact time with the heating device 506, which makes the air more fully absorb the heat emitted by the heating device 506, thereby improving the heating efficiency of the air, making the delivered hot air temperature higher and more uniform, and enhancing the heat exchange effect of the whole heat exchange device; The spirally flowing airflow forms a kind of turbulent flow state, which can promote the mixing of hot air in the second flow part 5042, and the hot air constantly collides and merges with each other during the flow process, so that the heat can be more evenly spread to the whole airflow, compared with the linearly flowing airflow, the spirally flowing airflow can effectively avoid the situation of local temperature being too high or too low, ensure that the temperature of the hot air entering the second gas flow path 505 is more balanced, and thereby improve the quality of heat exchange.

[0059] As a preferred example of the present application, the fan assembly 5 includes a first air supply device and a second air supply device, the first air supply device is a perfusion fan, the second air supply device is a axial flow fan, the first air supply device is communicated with the heating assembly 4 through the air supply pipeline 3, the air outlet side of the first air supply device is communicated with the air inlet side of the second air supply device, and the second air supply device is arranged in the direction of the air outlet side of the first air supply device.

[0060] Specifically, the flooding fan can generate a relatively uniform and wide wind field, and the air outlet of the flooding fan is concentrated in a plane, which is suitable for the air supply requirement of the long strip air outlet, and can make the air flow relatively uniformly in a certain range. The axial flow fan has the characteristics of large flow and low wind pressure, and can quickly transport a large amount of air. The flooding fan is used as the first air supply device, and the axial flow fan is used as the second air supply device, so that the advantages of the two can be combined. The first air supply device is communicated with the heating assembly 4 through the air supply pipeline 3, so that the hot air from the heating assembly 4 can be well distributed and adjusted before entering the second air supply device. The flooding fan can uniformly disperse the hot air on the air outlet plane, so as to avoid the hot air being concentrated in a certain area. Then, the axial flow fan further accelerates the transport of the hot air that has been preliminarily distributed, so that the distribution of the finally sent hot air in space is more uniform, which is beneficial to improving the heat exchange efficiency and the drying effect.

[0061] Preferably, the fan assembly 5 comprises a first air supply device and a second air supply device, the first air supply device is a flooding fan, the second air supply device is an axial flow fan, and the first air supply device is arranged on the air outlet side of the second air supply device.

[0062] The utility model discloses a kind of clothes processing equipment, including the heat exchange device as described in above embodiment, still including cabinet 1 and drum assembly 2, the drum assembly 2 is arranged in the inside of the cabinet 1, the fan assembly 5 is connected into drum assembly 2 by the hot air generated by the heating assembly 4, for drying clothes in drum assembly 2, other structures of the clothes processing equipment are same with prior art, no longer too much here.

[0063] As a preferred example of the utility model, the heating assembly 4 can be any one or a combination of two of electric heating assembly and heat pump heating assembly.

[0064] As an example of the utility model, the clothes processing equipment can use any one or a combination of multiple of direct drying, condensation drying and heat pump drying.

[0065] The above only is the preferred embodiment of the utility model, and does not use to limit the utility model, and any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
