Abstract
Description
[Technical Field]
[0001] The present invention relates to the field of dryer devices, and more particularly to dryer devices having honeycomb air ducts. [Background technology]
[0002] In everyday life, hair dryers are commonly used home appliances for quickly drying and styling washed hair. They use a motor to generate airflow to dry and style hair. Conventional hair dryers have a heating element directly installed inside the housing, and a blower blows hot air toward the heating element. This method results in significant heat loss and a relatively low air velocity. While some hair dryers have a honeycomb structure at the air outlet, this structure is often used to reduce noise and does not improve the air volume, air velocity, or air temperature of the dryer.
[0003] Chinese Patent Publication No. CN221044457U (Patent Document 1) relates to an energy-saving, power-saving electric hair dryer in the field of household products. It includes a housing with an air inlet and an air outlet facing each other at both ends, a wind guide sleeve inside the housing, a brushless motor, a ceramic heating element, and a mica frame inside the wind guide sleeve, a fan inside the brushless motor, the ceramic heating element fixed to the mica frame and fixed inside the wind guide sleeve via the mica frame, the ceramic heating element having a number of honeycomb holes to form a honeycomb shape, and a number of heating wires wound around the outside of the mica frame. In this solution, the ceramic heating element is honeycomb-shaped, so air gathers and stagnates around the ceramic heating element, increasing the time it comes into contact with the ceramic heating element, effectively heating the air. Under the condition that the hot air blown out reaches the same temperature, the honeycomb-shaped ceramic heating element can save 20-30% of electrical energy. In this patent, only honeycomb ceramic is used as the heating element, and the hot air cools down to a certain degree after it leaves the heating element, resulting in heat loss.
[0004] Chinese Patent Publication No. CN220212216U (Patent Document 2) relates to an intake air duct module for a noise-reducing hairdryer. It includes an inner air duct housing, a printed circuit board (PCB), a noise-reducing honeycomb mesh, a high-speed motor, and a heater. The PCB, noise-reducing honeycomb mesh, high-speed motor, and heater are sequentially mounted inside the inner air duct housing along the air duct flow. An air outlet and an air intake are provided at the front and rear ends of the inner air duct housing, respectively. A noise-reducing honeycomb mesh is added between the intake air duct where the PCB is installed and the motor's air intake. The noise-reducing honeycomb mesh is used to concentrate and rectify the airflow in the intake air duct, thereby stabilizing the airflow entering the motor and reducing the impact of airflow turbulence in the PCB on the motor's air intake, thereby reducing wind noise. In this patent, the honeycomb mesh installed at the outlet only serves to reduce noise and does not improve air speed or temperature. [Prior art documents] [Patent documents]

In response to the above-mentioned deficiencies of the prior art, a dryer device having a honeycomb-shaped air duct is provided. [Means for solving the problem]
[0007] To solve the above problems, the present invention adopts the following technical solutions.
[0008] A dryer apparatus is constructed, comprising a housing, with an air inlet and an air outlet formed on both sides of the housing and a fluid passage formed within the housing, with shielding cases installed at the air inlet and the air outlet, and with a blower, a control board connected to the blower, and a control button connected to the control board installed within the housing, wherein the dryer apparatus further comprises a heating assembly installed within the fluid passage, the heating assembly connected to the control board, and the control board controls operation of the blower and the heating assembly, the heating assembly including a honeycomb air duct, and the blower operates to introduce fluid into the fluid passage through the air inlet, change the temperature of the fluid by the heating assembly including the honeycomb air duct, and then discharge the fluid from the air outlet.

The two sets of silicone covers come into contact with each other, reducing fluid movement loss during fan operation and improving energy utilization. Furthermore, if reinforcing ribs are installed inside the housing, the contact area between the silicone cover and the housing can be reduced, further reducing the transmission of vibrations during fan operation. Installing a heat insulating sheet between the honeycomb air duct and the outlet can prevent the honeycomb air duct's outlet temperature from becoming too high and coming into direct contact with the outlet, providing greater safety. The shield cases on both sides of the fluid passages are connected in a detachable structure, which makes it easy to clean and replace the shield cases, making the entire dryer device more convenient and efficient to use, with larger air volume, lower noise, higher air speed, and better air temperature control, making it safer and more efficient to use.

FIG. DETAILED DESCRIPTION OF THE INVENTION
[0020] In order to clarify the objectives, technical solutions and advantages of the embodiments of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any creative effort are all within the scope of protection of the present invention.
[0021] As shown in FIGS. 1 and 2, a preferred embodiment of the hair dryer of the present invention includes a housing 10, which is divided into upper and lower parts. A handle 103 is formed in the lower part, and a fluid passage 102 is formed in the upper part. Openings are provided on both the left and right sides of the fluid passage, and a fluid passage shield case 20 is connected to the openings. A control board 40, a control button 50 connected to the control board, and a battery 30 are installed within the handle. A blower 60 and a heating assembly 80 are installed within the fluid passage, and both the blower and the heating assembly are connected to the control board. The control board controls the rotation of the blower to cause the fluid to flow within the fluid passage, and the control board controls the heating of the heating assembly. After passing through the heating assembly, the fluid is heated and blown out by the blower. The handle is used to adjust the direction of the heated fluid.
[0022] 2 and 3 , an inlet 105 is formed on the left side of a fluid passage 102, and an outlet 106 is formed on the right side. An inlet cover 200 is fitted to the inlet, and an outlet cover 201 is fitted to the outlet. A blower 60 is installed adjacent to the inlet, and a heating assembly 80 is installed adjacent to the outlet. The blower 60 operates to draw fluid into the passage through the inlet, blow the fluid toward the heating assembly to heat it, and then discharge the heated fluid through the outlet. To allow more of the fluid drawn into the blower to be discharged through the heating assembly, silicone covers 70 are fitted to the outside of both the blower and the heating assembly, and the two sets of silicone covers are connected to each other to prevent fluid loss when the blower blows the fluid toward the heating assembly.
[0023] 1 to 3 and 7 to 10, the housing 10 includes a left housing 100 and a right housing 101, and connecting rings 107 are installed on both the left and right sides of the upper part of the housing, wherein an engagement hole 1070 is installed on the connecting ring on one side of the intake port, and a rotary locking groove is installed on the connecting ring on one side of the outlet port, and the rotary locking groove includes an insertion groove 1071 installed on the connecting ring and a rotation groove 1072 connected to the insertion groove, and locking arms 1073 are installed on both sides of the insertion groove, and a stopper post 1074 is installed in the rotation groove, the outlet cover 201 is connected to the housing by the connecting ring, a shielding mesh is installed on the outlet cover, and a locking block 203 is installed on the inner wall of the end connected to the housing, and there is a gap 204 between the locking block and the shielding mesh 202. The locking block is inserted into the pivot groove through the insertion groove, the outlet cover is rotated to insert the locking block into the pivot groove, and the locking arm is placed in the gap, at which point the locking arm generates a lock on the locking block to connect the outlet cover to the housing. To detach the cover, simply rotate it in the opposite direction until the locking block contacts the stopper post, completing the connection between the outlet cover and the housing. The intake cover and outlet cover have the same structure, and the detachable connection between the intake cover and the housing can be completed by facing the locking block toward the engagement opening 1070 and pressing it until the locking block engages into the engagement opening. Both detachable connection methods are applicable to connecting the intake cover, the outlet cover, and the housing.
[0024] Furthermore, as shown in FIGS. 2 to 6 and 11 to 12, the housing is provided with multiple sets of reinforcing ribs 108 arranged circumferentially. A locking groove 1080 is formed in the center of each reinforcing rib near the blower. An outer boss 700 is provided on the outside of the silicone cover 70 connected to the blower, corresponding to the locking groove, to prevent the blower from rotating inside the housing. An inner convex ring 701 is provided on one end of the silicone cover, located close to the air intake port so that the blower can only be connected to the silicone cover from the opposite side. A stopper ring 104 is also provided at the air intake port to restrict the position of the blower. Fitting the silicone cover around the blower reduces the transmission of vibrations from the blower to the housing and reduces noise during operation. The reinforcing ribs not only increase the strength of the housing, but also reduce the contact area between the silicone cover and the housing, further reducing the transmission of vibrations from the blower. The heating assembly 80 is formed by a heating pipe set 800, which is formed by joining multiple heat tube units 805 in a honeycomb shape. Although the present invention uses a honeycomb shape, the heat tube units 805 may be joined in other shapes. That is, the use of the heat tube units 805 as air guides and their own heat generation are both within the scope of the present invention. Furthermore, the air duct may be formed in a curved or other irregular shape, which will not be described in detail here. An outer mica sheet 801 is installed on the exterior of the heating pipe set, and a silicone cover is fitted to the exterior of the outer mica sheet. An inner mica sheet 803 may be installed in the center of the heating pipe set, and both the outer mica sheet and the inner mica sheet may have a locking groove 804. A mica baffle 802 is installed in the locking groove. The mica baffle is placed at the outlet of the heating pipe set, ensuring a gap between the heating pipe set and the outlet.
[0025] The heating pipe set is connected to the control board and uses its own heat generated when powered on to heat the fluid blown by the fan after it contacts the heat tube, increasing the contact area between the fluid and the heat tube and improving heating efficiency. A heating element is installed between the fan and the heating pipe set. The fan blows the fluid toward the heating element to heat it, and the fluid then passes through the heating pipe set and is blown out through the outlet. This improves air speed and volume, but this method is slightly slower than heat transfer generated by the heating pipe set itself. Furthermore, a mica baffle installed between the heating pipe set and the outlet prevents the outlet temperature from becoming too high, making it safer and more efficient to use. Experimental comparisons have shown that the dryer device of this invention has various advantages over Laifen's blower in use, including significant advantages in air volume, noise, air speed, and air pressure. The specific test conditions, test methods, and test results are shown in Table 1.
[0026] [Table 1]
[0027] Furthermore, the left and right housings 100 and 1011 are connected by a locking structure, and a seal structure is provided at the connection point. The locking structure includes a locking block installed on the left housing and a bump installed on the right housing, and the bump is connected to the locking block to achieve locking. The seal structure includes a seal groove 1001 installed on the left housing and a seal post 1011 installed on the right housing, and the seal post is engaged in the seal groove to achieve sealing.
