Description

Technical Field

[0001] The present application relates to the technical field of air supply, and in particular to an air supply device and a skirting board. Background Art

[0002] In the related art, skirting heaters usually heat the air by convection and transfer heat by vertical convection. However, vertical convection skirting heaters can only emit heat upwards, and it is difficult to transfer heat to the surroundings. Moreover, the area above the ground and below the skirting cannot be heated, making it difficult to heat the feet of people, and inconvenient to use. Summary of the invention

[0003] Based on this, it is necessary to provide an air supply device and a skirting board to address the problem that the skirting board heater can only radiate heat upwards.

[0004] To achieve the above objectives, the technical solutions adopted in this application are as follows:

[0005] In a first aspect, an embodiment of the present application provides an air supply device, which is applied to a skirting board, and the air supply device includes:

[0006] The shell is divided into an air inlet bin and an air exhaust bin, the air inlet bin is provided with an air inlet on a side facing away from the air exhaust bin, the air exhaust bin is provided with a first air outlet on a side facing away from the air inlet bin, and a second air outlet is provided above the gravity direction, and the air inlet bin is connected with the air exhaust bin below the gravity direction;

[0007] A fan is installed at the connection point between the air inlet bin and the air exhaust bin, and the fan can absorb gas through the air inlet and discharge it through the first air outlet and the second air outlet.

[0008] Through the above design, the skirting board can provide heating in multiple directions, and can provide heating to the indoor area and the human foot area at the same time, thereby improving the user experience.

[0009] In one embodiment of the first aspect, the air supply device further includes a partition plate and a heating element, wherein the partition plate is fixed in the shell and divides the shell into the air inlet bin and the air exhaust bin, and the heating element is installed in the air exhaust bin and is located between the first air outlet and the fan;

[0010] The outer diameter of the fan is Ф, the distance between the fan axis and the lower end of the shell in the direction of gravity is h1, the distance between the center of the heating element and the lower end of the shell in the direction of gravity is h2, and it satisfies: h2

[0011] ​Through the above design, the output range of the fan is guaranteed, and the situation that the distance between the bottom of the fan and the shell is too large, resulting in insufficient air delivery, or the distance is too small, resulting in excessive wind flow loss, is avoided.

[0012] In one embodiment of the first aspect, the distance between the heating element and the axis of the fan is S1, and satisfies: 10mm+0.5Ф≤S1≤15mm+0.5Ф.

[0013] Through the above design, the overall structure of the air supply device can be made more compact, reducing the volume of the whole device. At the same time, the cold air delivered by the fan can be better exchanged with the heating element, ensuring the heat exchange rate and reducing the cross-flow diffusion of the cold air.

[0014] In one embodiment of the first aspect, the partition plate includes an arc segment, which is located at one end of the partition plate close to the fan, and the endpoint of the arc segment in the gravity direction and the axis of the fan are both located on a straight line L, and the straight line L forms an angle α with the horizontal direction and satisfies: 0°<α<20°.

[0015] Through the above design, the backflow wind generated during the conveying process of the fan is limited, and part of the airflow is prevented from flowing back to the air inlet bin under the guidance of the cross-flow impeller, thereby reducing wind loss.

[0016] In one embodiment of the first aspect, the partition plate further includes a sloped section, which is located on a side of the arc-shaped section facing away from the fan and forms an angle β with a horizontal direction and satisfies: 30°<β<60°.

[0017] Through the above design, the deflection angle of the airflow outflowing from the fan is reduced to avoid deflection at too large an angle causing the airflow to flow only through the upper half of the heating element, thereby resulting in low heat utilization efficiency and small outflow rate of the first air outlet.

[0018] In one of the embodiments of the first aspect, the air supply device further includes a diverter cone, which is installed above the gravity direction of the first air outlet, and the height of the diverter cone in the horizontal direction is h3, and satisfies: 10mm≤h3≤15mm.

[0019] Through the above design, the diameter of the air duct opening on the side of the second air outlet through which the warm air flows is limited, thereby limiting the amount of warm air supplied to the second air outlet, adjusting the warm air supply rates of the first air outlet and the second air outlet, and ensuring that the airflow to the first air outlet is blown out horizontally and the width of the entire machine is not too long.

[0020] In one of the embodiments of the first aspect, a distance between the splitter cone and a lower end of the shell in the gravity direction is h4, and satisfies: h2≤h4≤2.2h2.

[0021] Through the above design, the air outlet of the first air outlet is adjusted, thereby limiting the air flow ratio between the first air outlet and the second air outlet, thereby ensuring the heat dissipation effect of the air supply device.

[0022] In one embodiment of the first aspect, the distance between the heating element and the diverter cone is S2, and satisfies: 5mm≤S2≤10mm.

[0023] Through the above design, the diversion effect of the diversion cone on the warm air is guaranteed, and at the same time, the overall structure is guaranteed to be compact and the volume of the whole machine is reduced.

[0024] In one of the embodiments of the first aspect, the air supply device also includes an adjusting mechanism, which includes a screw, a connecting rod, a slider and a guide groove. The screw is rotatably arranged in the shell, one end of the connecting rod is threadedly connected to the screw, and the other end is connected to the slider. The guide groove is fixed in the shell, and the slider is slidably matched with the guide groove and the end away from the connecting rod is connected to the diverter cone.

[0025] Through the above design, the splitter cone can be moved up and down, and the relative height of the splitter cone can be adjusted, thereby limiting the air volume ratio between the first air outlet and the second air outlet.

[0026] In one of the embodiments of the first aspect, the air supply device also includes a guide plate, one end of the guide plate is located below the gravity direction of the air inlet, and the other end extends in a direction away from the air inlet in the downward direction of the gravity direction, and the fan is installed above the gravity direction of the guide plate.

[0027] Through the above design, the gap below the fan is reduced, thereby reducing the wind loss of the fan and ensuring the wind transmission rate of the fan.

[0028] In a second aspect, an embodiment of the present application further provides a skirting board, comprising the air supply device described in any of the above embodiments.

[0029] Through the above design, the skirting board can provide heating upwards and at the same time provide heating to the foot area of ​​the human body, thereby improving the user comfort.

[0030] Compared with the related art, the beneficial effect of the present application is as follows: the present application provides an air supply device and a skirting board, which can be used for multi-directional heating of skirting boards. The air supply device includes a shell and a fan, and the shell is divided into an air inlet bin and an air exhaust bin, and the fan is installed at the connection between the air inlet bin and the air exhaust bin. The shell is also provided with an air inlet located on one side of the air inlet bin, a first air outlet arranged opposite to the air inlet, and a second air outlet located above the gravity direction of the air exhaust bin. During the operation of the air supply device, the fan is driven after being powered on, and has absorbed gas from the air inlet. After the gas enters the air inlet bin, it enters the air exhaust bin under the transportation of the fan, and is finally discharged through the first air outlet and the second air outlet. In this way, when the skirting board is in heating operation, warm air can be provided to the upper side and the side facing the user, and while heating the room through the second air outlet, the heating needs of the human feet are guaranteed through the first air outlet, thereby increasing the heating area of ​​the skirting board and improving the user experience.

[0045] See also Figure 1 As shown, the embodiment of the present application provides an air supply device 100, which can realize air supply operations in multiple directions, meet the diverse needs of users, and improve user experience. It should be noted that the air supply device 100 provided in the embodiment of the present application can be used in various air supply equipment such as heating, cooling, and fresh air. For ease of understanding, the embodiment of the present application uses skirting as an application scenario to realize multi-directional heating operations of skirting.

[0046] Specifically, the air supply device 100 includes a housing 110 and a fan 120. The housing 110 is provided with an air inlet 113 and a plurality of air outlets. The fan 120 is installed in the housing 110, and during operation, absorbs indoor air from the air inlet 113 and discharges the air through the air outlets to meet the user's multi-directional air supply needs.

[0047] In this specific embodiment, the interior of the housing 110 is divided into an air inlet bin 111 and an air exhaust bin 112. An air inlet 113 is provided on the side of the air inlet bin 111 facing away from the air exhaust bin 112, and a first air outlet 114 is provided on the side of the air exhaust bin 112 facing away from the air inlet bin 111. A second air outlet 115 is provided above the gravity direction of the air exhaust bin 112, and the air inlet bin 111 and the air exhaust bin 112 are connected below the gravity direction. The fan 120 is installed at the connection between the air inlet bin 111 and the air exhaust bin 112 so as to absorb gas through the air inlet 113 and discharge it through the first air outlet 114 and the second air outlet 115.

[0048] The air inlet 113 is located above one side of the shell 110, and the fan 120 is arranged at the lower end of the air inlet 113 to ensure that a large amount of air can enter the air inlet bin 111 and be transported to the exhaust bin 112 by the fan 120, so as to ensure the air supply rate of the air supply device 100. At the same time, the first air inlet 113 is located at the bottom of the side of the shell 110 away from the air inlet 113 to achieve air supply to the foot area of ​​the human body. The second air inlet 113 is located at the top of the shell 110 to discharge the air flow upward to ensure the indoor air supply demand. In addition, the size of the air inlet 113 is much larger than the size of the first air outlet 114 and the second air outlet 115 to avoid the loss of air during the flow process, resulting in insufficient air outlet of the first air outlet 114 and the second air outlet 115, and further ensure the air supply rate of the air supply device 100.

[0049] It is understandable that the air inlet 113, the first air outlet 114 and the second air outlet 115 are all provided with a grille structure to protect the air outlet. In addition, the air supply device 100 provided in the present application is not limited to the air outlet in two directions. In other embodiments, the air supply device 100 can also provide air outlets on different sides of the housing 110 according to the needs of the user to achieve air supply in more directions.

[0050] See also Figure 2 As shown, in some embodiments, the air supply device 100 further includes a partition plate 130 and a heating element. The partition plate 130 is fixed in the housing 110 and divides the housing 110 into an air inlet bin 111 and an air exhaust bin 112. The heating element is installed in the air exhaust bin 112 and is located between the first air outlet 114 and the fan 120. The outer diameter of the fan 120 is Ф, the distance between the axis of the fan 120 and the lower end of the housing 110 in the direction of gravity is h1, and the distance between the center of the heating element and the lower end of the housing 110 in the direction of gravity is h2, and it satisfies: h2

[0051] Specifically, the top and side of the partition plate 130 are sealed and connected to the housing 110, and only the bottom side is spaced from the housing 110 to connect the air inlet bin 111 and the air exhaust bin 112, so that the airflow is transported to the air exhaust bin 112 through the air inlet bin 111. The fan 120 is installed on the side of the air inlet bin 111 close to the air exhaust bin 112, and is located at the bottom of the partition plate 130 to transport the airflow to the air exhaust bin 112. The heating element is installed on the side of the air exhaust bin 112 close to the air inlet bin 111, and is also located at the bottom of the partition plate 130, so that after the fan 120 transports the cold air to the air exhaust bin 112, the cold air flows through the heating element and exchanges heat with the heating element to form warm air, and then is discharged through the first air outlet 114 and the second air outlet 115 to meet the indoor heating demand.

[0052] ​Furthermore, the fan 120 adopts a cross-flow impeller, and h1 is the distance between the axis of the fan 120 and the housing 110 in the direction of gravity, that is, the height range of h1 is the output area of ​​the fan 120. By setting the outer diameter Ф of the fan 120 to be greater than or equal to h1, the output range of the fan 120 is guaranteed, avoiding the situation where the distance between the bottom of the fan 120 and the housing 110 is too large, resulting in insufficient air delivery, or the distance is too small, resulting in excessive wind flow loss.

[0053] Furthermore, by setting the distance h2 between the center of the heating element and the shell 110 in the gravity direction smaller than h1, the cold air can flow through the heating element to the maximum extent after being transported to the exhaust bin 112 by the fan 120, so as to improve the heat exchange efficiency of the air and ensure the supply of warm air.

[0054] Of course, in other embodiments, the heating element may also be a refrigeration heat exchanger to meet the demand for cold air supply. The specific principles are the same as those in the above embodiments and will not be repeated here.

[0055] Continue reading Figure 3 As shown, in some embodiments, the partition plate 130 includes an arc segment 131, which is located at one end of the partition plate 130 close to the fan 120, and the upper end point of the arc segment 131 in the gravity direction and the axis of the fan 120 are both located on a straight line L, and the straight line L forms an angle α with the horizontal direction and satisfies: 0°<α<20°.

[0056] For example, the angle α between the straight line L and the horizontal direction can be 1°, 5°, 7°, 9°, 11°, 13°, 15°, 17°, 19°, etc., which can be selected according to the size design of the fan 120 and is not specifically limited here. By setting the above angle, the return wind generated during the conveying process of the fan 120 is limited, and part of the airflow is prevented from returning to the air inlet bin 111 under the guidance of the cross-flow impeller, thereby reducing wind loss.

[0057] Furthermore, the partition plate 130 further includes a sloped surface section 132 , which is located on a side of the arc-shaped section 131 facing away from the fan 120 , and forms an angle β with the horizontal direction, and satisfies: 30°<β<60°.

[0058] For example, the angle β between the inclined surface section 132 and the horizontal direction can be 31°, 35°, 40°, 45°, 50°, 55°, 57°, 59°, etc., which can be selected according to actual needs and is not specifically limited here. By setting the above angle, the deflection angle of the airflow outflowing from the fan 120 is reduced to avoid the deflection at too large an angle causing the airflow to flow only through the upper half of the heating element, thereby resulting in low heat utilization efficiency and a small outflow rate of the first air outlet 114.

[0059] In some embodiments, the air supply device 100 also includes a guide plate 160, one end of which is located below the air inlet 113 in the direction of gravity, and the other end extends in a direction away from the air inlet 113 in the direction of gravity, and the fan 120 is installed above the guide plate 160 in the direction of gravity.

[0060] Specifically, the guide plate 160 is arranged to be inclined along the air inlet 113 toward the first air outlet 114, so that when the fan 120 is installed above the guide plate 160, the conveying airflow of the fan 120 is guided to ensure that the airflow can flow into the exhaust bin to the maximum extent. At the same time, the arrangement of the guide plate 160 reduces the gap below the fan 120, thereby reducing the wind loss of the fan 120 and ensuring the wind delivery rate of the fan 120.

[0061] Preferably, an arc-shaped depression is provided on one side of the guide plate 160 close to the fan 120 , so as to match the circular structure of the fan 120 and further enhance the guidance of the output airflow of the fan 120 .

[0062] Furthermore, the distance between the heating element and the axis of the fan 120 is S1, and satisfies: 10mm+0.5Ф≤S1≤15mm+0.5Ф.

[0063] It is understandable that the distance S1 between the heating element and the axis of the fan 120 is 10mm-15mm larger than the radius of the fan 120, that is, the distance between the heating element and the fan 120 is 10mm-15mm. Exemplarily, the distance between the heating element and the fan 120 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc., which can be reasonably selected according to the actual size of the product, and is not specifically limited here. Through the above-mentioned size setting, the overall structure of the air supply device 100 can be more compact and the volume of the whole machine can be reduced. At the same time, the cold air transported by the fan 120 can be better exchanged with the heating element 140, ensuring the heat exchange rate and reducing the cross-flow diffusion of the cold air.

[0064] In some embodiments, the air supply device 100 further includes a diverter cone 150 , which is installed above the first air outlet 114 in the direction of gravity. The diverter cone 150 has a horizontal height of h3 and satisfies: 10 mm ≤ h3 ≤ 15 mm.

[0065] Specifically, the diverter cone 150 is arranged between the first air outlet 114 and the second air outlet 115, and together with the partition plate 130, forms an exhaust passage for the second air outlet 115, so that the warm air formed by heat exchange of the heating element is diverted at the diverter cone 150, limiting the air flow rate of the first air outlet 114 and the second air outlet 115, and preventing a large amount of warm air from being discharged from the first air outlet 114 which is closer.

[0066] For example, the height h3 of the diverter cone 150 in the horizontal direction can be 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, etc., which can be reasonably selected according to actual needs and is not specifically limited here. By setting the height dimension of the diverter cone 150 in the horizontal direction, the diameter of the air duct on the side of the second air outlet 115 is limited, thereby limiting the amount of warm air supplied to the second air outlet 115, adjusting the warm air supply rate of the first air outlet 114 and the second air outlet 115, and ensuring that the airflow to the first air outlet 114 is blown out horizontally and the width of the whole machine is not too long.

[0067] Furthermore, the distance between the diverter cone 150 and the lower end of the housing 110 in the gravity direction is h4, and satisfies: h2≤h4≤2.2h2. By adjusting the distance between the bottom of the diverter cone 150 and the housing 110, the air volume of the first air outlet 114 can be adjusted, thereby limiting the air volume ratio between the first air outlet 114 and the second air outlet 115, thereby ensuring the heat dissipation effect of the air supply device 100.

[0068] In a group of comparative embodiments, by setting different ratios of h4 to h2, the simulated air flow ratio of the first air outlet 114 and the second air outlet 115 is obtained, and the specific parameters are shown in Table 1.

[0069] h4:h2 <![CDATA[First air outlet flow rate (m 3 / s)]]> <![CDATA[Second air outlet flow rate (m 3 / s)]]> Air flow ratio 0.8 0.04 0.07 0.57 1 0.106 0.124 0.85 1.2 0.121 0.111 1.1 1.4 0.136 0.109 1.25 1.6 0.146 0.097 1.5 1.8 0.167 0.073 2.3 2 0.206 0.042 4.9 2.2 0.234 0.01 23.4

[0070] Table 1

[0071] It can be seen from Table 1 that when h2≤h4≤2.2h2 is satisfied, the simulated airflow ratio of the first air outlet 114 and the second air outlet 115 is between 0.85-23.4, and the heat dissipation effect of the air supply device 100 is better.

[0072] Furthermore, the distance between the heating element and the diverter cone 150 is S2, and satisfies: 5mm≤S2≤10mm.

[0073] For example, the distance S2 between the heating element and the diverter cone 150 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc., which can be reasonably selected according to actual needs and is not specifically limited here. By setting the above distance, the diverter cone 150 can ensure the diversion effect of the warm air, while ensuring the overall structure is compact and reducing the volume of the whole machine.

[0074] Continue reading Figure 4 and Figure 5As shown, in some embodiments, the air supply device 100 further includes an adjustment mechanism 170, and the adjustment mechanism 170 includes a screw rod 171, a connecting rod 172, a slider 173, and a guide groove 174. The screw rod 171 is rotatably disposed in the housing 110, one end of the connecting rod 172 is threadedly connected to the screw rod 171, and the other end is connected to the slider 173, the guide groove 174 is fixed in the housing 110, and the slider 173 is slidably matched with the guide groove 174 and the end away from the connecting rod 172 is connected to the diverter cone 150.

[0075] Specifically, the bottom of the screw 171 can be rotatably installed in the housing 110 through a bearing or a bushing, and the top plate extends out of the housing 110 and is provided with a knob structure, so that the screw 171 can be rotated by turning the knob by external force. The guide groove 174 can be defined by two rods arranged opposite to each other, one end of the connecting rod 172 is threadedly engaged with the screw 171, and the other end is engaged with the guide groove 174 through the slider 173, so that when the screw 171 rotates, the connecting rod 172 cannot rotate with the screw 171, and can only move up and down along the guide groove 174, thereby controlling the up and down movement of the diverter cone 150 and adjusting the relative height of the diverter cone 150.

[0076] Of course, in other embodiments, the splitter cone 150 can also be adjusted up and down by other driving methods, such as a telescopic workpiece such as a hydraulic cylinder or a pneumatic cylinder to directly control the up and down movement of the splitter cone 150, or an indirect method such as a gear transmission or a chain transmission to achieve the position adjustment of the splitter cone 150, etc., which is not specifically limited in this embodiment.

[0077] An embodiment of the present application further provides a skirting board, comprising the air supply device 100 in any of the above embodiments.

[0078] This embodiment has the air supply device 100 in any of the above embodiments, and therefore has all the beneficial effects of the air supply device 100 in any of the above embodiments, which will not be described in detail here.

[0079] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
