Generally, a clothes dryer includes a drying cylinder (not shown in the figure) capable of containing clothes to be dried and a drying passage 2 communicating with the drying cylinder, wherein a fan 1 is arranged at one end of the drying passage 2, and One end communicates with the drying cylinder, so that the airflow guided by the fan 1 can enter the drying cylinder. And the heating device 3 capable of dissipating heat is arranged in the drying channel 2, so that the airflow in the drying channel 2 can be heated during the process of flowing through the heating device 3, so that the air becomes dry and hot and enters the drying cylinder. In this case, the moisture contained in the clothes in the drying drum is evaporated under the action of the dry hot air flow, and is discharged to the outside of the drying drum along with the air flow when the air flow in the drying drum is discharged, thereby reducing the amount of clothes in the drying drum. The moisture content in the fabric makes the wet clothes dry gradually. As an example, the drying passage 2 may be a pipeline structure capable of guiding airflow into the drying cylinder, and the fan 1 includes a volute 11 communicated with the pipeline structure and a fan 12 arranged in the volute, and the fan 12 rotates to make the The air is introduced into the above-mentioned pipeline structure and flows into the drying cylinder along the pipeline structure, so as to enter the drying cylinder to dry clothes. Preferred implementations of the present invention will be described in detail below in combination with the above implementations of the clothes dryer.

Referring to FIG. 1 first, FIG. 1 is a schematic diagram of the installation of the heating device of the present invention in a clothes dryer. As shown in FIG. 1 , specifically, the heating device 3 includes a heating member 31 and a flow blocking member 32 , wherein the heating member 31 is arranged in the drying channel 2 , and the flow blocking member 32 is arranged on the heating member 31 . The flow blocking member 32 can make the airflow in the drying channel 2 form a vortex when flowing through the surface of the heating member 31 , so as to prolong the heating time of the airflow by the heating member 1 . Specifically, when the airflow flows along the surface of the heating member 31, the bottom airflow close to the heating member 31 is blocked by the flow blocking member 32, and the flow velocity of the bottom airflow is reduced, while the top layer airflow slightly farther away from the heating member 31 is not blocked. The normal velocity of flow hindered, so the top-level airflow is relatively thinner because the airflow behind it flows forward faster, so that the bottom-level airflow flows to the rear of the top-level airflow and merges with the top-level airflow to form a circular flow along the surface of the heating member 31 vortex. Since the above-mentioned airflow flows in the above-mentioned vortex mode, on the one hand, compared with the way of directly flowing through the heating member 31, the time for the airflow to pass through the heating member 31 is prolonged, thereby prolonging the contact time between the airflow and the heating member 31, so that the airflow More heat can be absorbed from the heating member 31 during the process of flowing through the heating member 31 , preventing the airflow from flowing out of the drying channel 2 when the airflow is not fully heated, and ensuring the temperature of the airflow after heating. On the other hand, under the blocking effect of the flow blocking member 32, the confluence effect between the top airflow and the bottom airflow in the airflow is enhanced, so that the bottom airflow which is closer to the heating member 31 can mix with the top airflow after being rapidly heated (or transfer heat to the top-level airflow with a slightly lower temperature), thereby increasing the overall heating speed of the airflow and improving the overall heating efficiency of the airflow. Moreover, the improvement of the above-mentioned heating efficiency is not achieved by raising the temperature of the heating member 31 at all. While the heating efficiency is improved, it also ensures that the energy consumption of the clothes dryer will not increase, so that the clothes dryer can dry clothes in an energy-saving and efficient manner. .

In a possible implementation manner, the heating member 31 is a heating pipe, and the heating pipe is straight and tubular, and the flow blocking member 32 is arranged on the straight tubular heating pipe to prolong the air flow flowing along the heating pipe. heating time.

As a preferred implementation manner, the heating member 31 is a serpentine heating pipe, and the flow blocking member 32 is arranged on the serpentine heating pipe. Through the above-mentioned serpentine arrangement, the heating pipe with a larger length can be accommodated in the drying channel 2, and the contact area between the airflow and the heating member 31 is increased, so that the overall heat dissipation area of the heating member 31 is increased, so that the airflow can be heated faster. heating. The preferred embodiments of the present invention will be further expanded below in combination with the above preferred embodiments.

Referring next to FIG. 2 , FIG. 2 is a schematic structural diagram of the heating device of the present invention. As shown in Figure 2, according to the orientation in Figure 2, the specific structure of the serpentine heating pipe can be as follows: the serpentine heating pipe includes five straight pipe sections 311 arranged at intervals in the drying channel 2 from top to bottom and can A plurality of curved pipe sections 312 connecting the ends of two adjacent straight pipe sections, the flow blocking member 32 is arranged on the straight pipe section 311, so that the air flow flows from the right side of the heating pipe to the left side of the heating pipe During the process, a vortex can be formed on the straight pipe section 311 many times, so that the contact time between the air flow and the heating pipe (mainly the straight pipe section 311 ) is prolonged. That is to say, the arrangement of the above-mentioned serpentine heating pipe and the flow blocking member 32 can increase the contact area between the airflow and the heating pipe (or increase the heat dissipation area of the heating pipe) while also prolonging the flow of the airflow through the heating pipe. The tube process further improves the heating efficiency of the airflow.

Continuing to refer to FIG. 1 and FIG. 2 , as a preferred embodiment, the flow blocking member 32 includes a plurality of concave structures arranged at intervals on the heating pipe, and the concave structures allow airflow to flow into the concave structures and form vortex. Specifically, a plurality of convex strips 321 are arranged at intervals on the straight pipe section 311, and the above-mentioned concave structure is a groove 322 formed between the two convex strips 321; or the concave structure is directly arranged on the straight pipe section 311 The groove 322 on. When the air flow flows along the straight pipe section 311 of the heating member 31 , the bottom air flow can be blocked by the groove wall of the groove 322 to form a vortex with the top air flow.

In order to ensure that the airflow flowing along the circumferential pipe wall of the straight pipe section 311 can be fully heated, preferably, the groove 322 is an annular groove provided on the straight pipe section 311 .

In a possible implementation manner, the width of the notch of the groove 322 is greater than the width of the bottom of the groove. Or the width of the notch of the groove 322 is smaller than the width of the groove bottom.

In a possible implementation manner, the sidewall surface of the trench 322 is a straight slope. Alternatively, the sidewall surface of the groove 322 is an arc-shaped slope.

With regard to the above embodiment, it can be understood that the specific shape of the groove 322 is not limiting, and the two formation methods and the four shape features of the above two grooves 322 can be freely combined according to the heating requirements. The following will combine the above six A preferred structure of the trench 322 will be described by combining various embodiments of the trench 322 .

Referring to FIG. 3 again, FIG. 3 is a schematic structural diagram of a heating device according to a first embodiment of the present invention. As shown in FIG. 3 , a plurality of ridges 321 are arranged at intervals on the straight pipe section 311 of the heating pipe, and grooves 322 are formed between two adjacent ridges 321 . And the width of the notch of the groove 322 is smaller than the width of the groove bottom. As an example, the protruding line 321 is an annular protruding line with an approximately isosceles trapezoidal cross-sectional shape disposed on the straight pipe section 311 , so that the sidewall surface of the groove 322 is a straight slope. In this case, when the bottom airflow enters the groove 322, the inward straight slope on the groove 322 can prevent the low-layer airflow from quickly flowing out of the groove 322, so that there is enough contact time between the airflow and the heating tube, The airflow can be heated more fully.

Continue to refer to FIG. 4 , which is a schematic structural diagram of a heating device according to a second embodiment of the present invention. As shown in FIG. 4 , a plurality of ridges 321 are arranged at intervals on the straight pipe section 311 of the heating pipe, and grooves 322 are formed between two adjacent ridges 321 . And the width of the notch of the groove 322 is greater than the width of the groove bottom. As an example, the convex strip 321 is an annular convex strip with a semicircular cross-sectional shape disposed on the straight pipe section 311 , so that the sidewall surface of the groove 322 is an arc-shaped slope. In this case, when the bottom airflow enters the groove 322, the low-layer airflow can quickly flow out of the groove 322 along the outwardly expanding arc slope of the groove 322, ensuring the flow speed of the eddy current, so that the heating process of the airflow does not If it is too long, the hot and dry air can quickly enter the drying cylinder, ensuring the drying efficiency of the dryer.

Finally, refer to FIG. 5 . FIG. 5 is a schematic structural diagram of a heating device according to a third embodiment of the present invention. As shown in FIG. 5 , a plurality of grooves 322 are arranged directly and at intervals on the straight pipe section 311 of the heating pipe. The width of the notch of the groove 322 is larger than the width of the groove bottom and the sidewall surface of the groove is an arc-shaped slope. As an example, the groove 322 is an annular groove with a semicircular cross section, so that the side walls of the groove 322 are moderately shrunk, so that the obstruction of the groove 322 to the airflow is neither too large nor too small, The airflow has a moderate flow velocity, so that the airflow can be heated more fully and the heating process can be avoided from being too long.

Those skilled in the art can understand that, firstly, the heating member 31 is not limited to the serpentine shape shown in FIGS. shape) or other shapes such as stepped shape (including the bent extension part similar to serpentine shape), as long as the shape of the heating member 31 can make it have a large enough heating area. Secondly, although the three preferred implementations of the groove 322 are described in conjunction with the combination of four specific shape features such as the width of the notch and the bottom of the groove and the shape of the side wall, it is obvious that the shape features of the groove 322 are not Limited to the above four types, for example, the width of the notch of the groove 322 may also be equal to the width of the groove bottom, and the sidewall surface of the groove 322 may also be a vertical plane. The specific shape of the groove 322 is sufficient as long as it can meet the functional requirements of forming eddy currents. All the changes of the above shapes are within the principle and protection scope of the present invention.

To sum up, the clothes dryer of the present invention includes a drying system, the drying system includes a drying channel and a heating device is arranged in the drying channel. Wherein, the heating device includes a heating pipe and concave structures disposed on the heating pipe at intervals. Through the above settings, the airflow can form a vortex when it flows through the surface of the heating tube under the blocking effect of the concave structure, thereby prolonging the heating time of the heating tube for the airflow, ensuring that the airflow can be fully heated by the heating tube without increasing The heating efficiency of the airflow is improved under the premise of the dryer consuming energy.

So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings, but those skilled in the art will easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
