Description

Technical Field

[0001] This application relates to the field of air supply technology, and in particular to an air supply device and a skirting board. Background Technology

[0002] In related technologies, baseboard heaters typically heat the air using convection, transferring heat through vertical convection. However, vertical convection baseboard heaters can only radiate heat upwards, making it difficult to transfer heat to the surrounding areas. Furthermore, they cannot heat the area above the floor but below the baseboard, making it difficult to warm the feet and inconvenient to use. Utility Model Content

[0003] Therefore, it is necessary to provide a ventilation device and a baseboard to address the problem that baseboard heaters can only radiate heat upwards.

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

[0005] In a first aspect, embodiments of this application provide an air supply device applied to a skirting board, the air supply device comprising:

[0006] The shell is internally divided into an air inlet chamber and an air outlet chamber. The air inlet chamber has an air inlet on the side opposite to the air outlet chamber, and the air outlet chamber has a first air outlet on the side opposite to the air inlet chamber. A second air outlet is provided above the gravity direction. The air inlet chamber and the air outlet chamber are connected below the gravity direction.

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

[0008] The above design enables the skirting board to provide heating from multiple directions, simultaneously heating the room and the area around the feet, thus 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, the partition plate being fixed inside the housing and dividing the housing into the air inlet chamber and the air outlet chamber, the heating element being installed in the air outlet chamber and located between the first air outlet and the fan;

[0010] The outer diameter of the fan is Ф, the distance between the fan shaft and the lower end of the housing in the direction of gravity is h1, and the distance between the center of the heating element and the lower end of the housing in the direction of gravity is h2, and the following conditions are met: h2

[0011] ​The above design ensures the output range of the fan and avoids situations where the gap between the bottom of the fan and the casing is too large, resulting in insufficient air delivery, or the gap is too small, resulting in excessive loss of airflow.

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

[0013] The above design allows for a more compact overall structure of the air supply device, reducing the overall size of the unit. Simultaneously, it ensures better heat exchange between the cold air delivered by the fan and the heating element, guaranteeing the heat exchange rate and reducing the cross-flow and diffusion of cold air.

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

[0015] The above design limits the backflow air generated during the fan's operation, preventing some airflow from flowing back to the air inlet chamber under the guidance of the cross-flow impeller, thus reducing wind power loss.

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

[0017] The above design reduces the deflection angle of the airflow from the fan, avoiding excessive deflection that causes the airflow to flow only through the upper half of the heating element, resulting in low heat utilization efficiency and small outflow from the first air outlet.

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

[0019] The above design limits the diameter of the air duct on one side of the second air outlet to restrict the flow of warm air, thereby limiting the amount of warm air supplied to the second air outlet, adjusting the warm air supply rate of the first and second air outlets, and ensuring that the airflow to the first air outlet is blown out horizontally and that the width of the whole unit is not too long.

[0020] In one embodiment of the first aspect, the distance between the diverter cone and the lower end of the housing in the direction of gravity is h4, and satisfies: h2≤h4≤2.2h2.

[0021] By adjusting the air volume of the first air outlet, the air flow ratio between the first air outlet and the second air outlet is limited, 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 flow divider cone is S2, and satisfies: 5mm≤S2≤10mm.

[0023] The above design ensures the effective distribution of warm air by the diversion cone, while also ensuring a compact overall structure and reducing the overall size of the unit.

[0024] In one embodiment of the first aspect, the air supply device further includes an adjustment mechanism, which includes a screw, a connecting rod, a slider, and a guide groove. The screw is rotatably disposed within the housing. 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 within the housing. The slider slides into the guide groove, and the end of the slider away from the connecting rod is connected to the diverting cone.

[0025] Through the above design, the flow divider cone can be moved up and down to adjust its relative height, thereby limiting the airflow ratio between the first air outlet and the second air outlet.

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

[0027] The above design reduces the lower gap of the fan, thereby reducing the fan's wind power loss and ensuring the fan's wind power delivery rate.

[0028] Secondly, this application also provides a skirting board, including the air supply device described in any of the above embodiments.

[0029] Through the above design, the skirting board can heat the area around the feet while providing upward heating, thus improving user comfort.

[0030] Compared to related technologies, the beneficial effects of this application are as follows: This application provides an air supply device and a skirting board, which can be used for multi-directional heating of the skirting board. The air supply device includes a housing and a fan. The housing is internally divided into an air inlet chamber and an air outlet chamber, and the fan is installed at the connection between the air inlet chamber and the air outlet chamber. The housing also has an air inlet located on one side of the air inlet chamber, a first air outlet opposite to the air inlet, and a second air outlet located above the gravity direction of the air outlet chamber. During the operation of the air supply device, the fan is driven after being powered on, and has already absorbed gas from the air inlet. After the gas enters the air inlet chamber, it is transported into the air outlet chamber by the fan, and finally discharged through the first and second air outlets. In this way, when the skirting board is used for heating, it can provide warm air upwards and to the side facing the user. While heating the room through the second air outlet, it also ensures the heating needs of the feet through the first air outlet, thereby increasing the heating area of ​​the skirting board and improving the user experience.

[0045] See Figure 1 As shown, an embodiment of this application provides an air supply device 100 that can perform air supply operations in multiple directions, meeting diverse user needs and improving user experience. It should be noted that the air supply device 100 provided in this application embodiment can be used in various heating, cooling, and fresh air supply equipment. For ease of understanding, this application embodiment uses skirting boards as an application scenario to achieve multi-directional heating operations on the skirting boards.

[0046] Specifically, the air supply device 100 includes a housing 110 and a fan 120. The housing 110 has an air inlet 113 and multiple air outlets. The fan 120 is installed inside the housing 110 and, during operation, draws indoor air from the air inlet 113 and discharges the air through the various 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 chamber 111 and an air outlet chamber 112. An air inlet 113 is provided on the side of the air inlet chamber 111 facing away from the air outlet chamber 112, and a first air outlet 114 is provided on the side of the air outlet chamber 112 facing away from the air inlet chamber 111. A second air outlet 115 is provided above the air outlet chamber 112 in the direction of gravity, and the air inlet chamber 111 and the air outlet chamber 112 are connected below in the direction of gravity. A fan 120 is installed at the connection between the air inlet chamber 111 and the air outlet chamber 112 to absorb gas through the air inlet 113 and discharge it through the first air outlet 114 and the second air outlet 115.

[0048] An air inlet 113 is located on the upper side of one side of the housing 110, and a fan 120 is positioned at the lower end of the air inlet 113 to ensure that a large amount of air can enter the air intake chamber 111 and be transported to the exhaust chamber 112 by the fan 120, thus ensuring the air supply rate of the air supply device 100. Simultaneously, the first air inlet 113 is located at the bottom of the housing 110 on the side away from the air inlet 113, to provide air supply to the foot area. The second air inlet 113 is located at the top of the housing 110 to exhaust air upwards, ensuring indoor air supply needs. Furthermore, the size of the air inlet 113 is significantly larger than the sizes of the first air outlet 114 and the second air outlet 115 to avoid insufficient airflow from the first air outlet 114 and the second air outlet 115 due to air loss during airflow, further ensuring the air supply rate of the air supply device 100.

[0049] Understandably, the air inlet 113, the first air outlet 114, and the second air outlet 115 are all equipped with grille structures to protect the air outlets. Furthermore, the air supply device 100 provided in this application is not limited to air outlets in two directions. In other embodiments, the air supply device 100 can also have air outlets on different sides of the housing 110 according to user needs, to achieve air supply operations 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 inside the housing 110 and divides the housing 110 into an air inlet chamber 111 and an air outlet chamber 112. The heating element is installed in the air outlet chamber 112 and 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, satisfying: h2

[0051] Specifically, the top and sides of the partition plate 130 are sealed to the housing 110, with only the bottom side forming a gap to connect the air inlet chamber 111 and the air outlet chamber 112, facilitating airflow from the air inlet chamber 111 to the air outlet chamber 112. The fan 120 is installed on the side of the air inlet chamber 111 near the air outlet chamber 112 and at the bottom of the partition plate 130 to direct airflow to the air outlet chamber 112. The heating element is installed on the side of the air outlet chamber 112 near the air inlet chamber 111 and also at the bottom of the partition plate 130. After the fan 120 delivers cold air to the air outlet chamber 112, the cold air flows through the heating element and exchanges heat with it to form warm air, which is then discharged through the first air outlet 114 and the second air outlet 115 to meet indoor heating needs.

[0052] ​Furthermore, the fan 120 adopts a cross-flow impeller, and h1 is the distance between the shaft of the fan 120 and the casing 110 in the direction of gravity. That is, the output area of ​​the fan 120 is within the height range of h1. 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, and the insufficient air volume delivery caused by the excessive distance between the bottom of the fan 120 and the casing 110, or the excessive loss of air flow caused by the excessive distance between the distance between the bottom of the fan 120 and the casing 110, is avoided.

[0053] Furthermore, by setting the distance h2 between the center of the heating element and the housing 110 in the direction of gravity to be less than h1, the cold air can circulate to the heating element to the maximum extent after being delivered to the exhaust chamber 112 by the fan 120, thereby improving the heat exchange efficiency of the air and ensuring the supply of warm air.

[0054] Of course, in other embodiments, the heating element can also be a refrigeration heat exchanger to meet the cold air supply requirements. The specific principle is the same as 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 near the fan 120. The upper end of the arc segment 131 in the direction of gravity and the axis of the fan 120 are both located on a straight line L. 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., and can be selected according to the size design of the fan 120. No specific limitation is made here. By setting the above angle, the backflow air generated during the fan 120's conveying process is limited, preventing some airflow from flowing back to the air inlet chamber 111 under the guidance of the cross-flow impeller, thus reducing wind power loss.

[0057] Furthermore, the partition plate 130 also includes an inclined section 132, which is located on the side of the arc section 131 facing away from the fan 120 and forms an angle β with the horizontal direction, satisfying: 30°<β<60°.

[0058] For example, the angle β between the inclined section 132 and the horizontal direction can be 31°, 35°, 40°, 45°, 50°, 55°, 57°, 59°, etc., and can be selected according to actual needs, without specific limitations here. By setting the above angle, the deflection angle of the airflow out of the fan 120 is reduced, avoiding excessively large deflection angles that cause the airflow to only flow through the upper half of the heating element, resulting in low heat utilization efficiency and small outflow from the first air outlet 114.

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

[0060] Specifically, the guide plate 160 is inclined along the air inlet 113 towards the first air outlet 114, thereby guiding the airflow of the fan 120 when it is installed above the guide plate 160, ensuring that the airflow can flow into the exhaust chamber to the maximum extent. At the same time, the arrangement of the guide plate 160 reduces the lower gap of the fan 120, thereby reducing the wind power loss of the fan 120 and ensuring the wind power delivery rate of the fan 120.

[0061] Preferably, the guide plate 160 has an arc-shaped recess on the side near the fan 120, so as to match the circular structure of the fan 120 and further enhance the guidance of the airflow output by 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] Understandably, 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, i.e., the distance between the heating element and the fan 120 is 10mm-15mm. For example, the distance between the heating element and the fan 120 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc., and can be reasonably selected according to the actual size of the product; no specific limitation is made here. Through the above-mentioned dimensional settings, the overall structure of the air supply device 100 can be made more compact, reducing the overall size of the unit. At the same time, it allows the cold air delivered by the fan 120 to exchange heat better with the heating element 140, ensuring the heat exchange rate and reducing the cross-flow and diffusion of cold air.

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

[0065] Specifically, the diversion cone 150 is disposed between the first air outlet 114 and the second air outlet 115, and together with the partition plate 130, forms the exhaust channel of the second air outlet 115. This allows the warm air generated by heat exchange through the heating element to be diverted at the diversion cone 150, limiting the airflow between the first air outlet 114 and the second air outlet 115, and preventing a large amount of warm air from being discharged from the closer first air outlet 114.

[0066] For example, the horizontal height h3 of the diversion cone 150 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc., and can be reasonably selected according to actual needs, without being specifically limited here. By setting the horizontal height of the diversion cone 150, the diameter of the air duct opening on one 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, while ensuring that the airflow to the first air outlet 114 is blown out horizontally and the width of the whole unit is not too long.

[0067] Furthermore, the distance between the diverter cone 150 and the lower end of the housing 110 in the direction of gravity 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 flow ratio between the first air outlet 114 and the second air outlet 115, ensuring the heat dissipation effect of the air supply device 100.

[0068] In a set of comparative embodiments, by setting different ratios of h4 to h2, the simulated airflow ratio of the first air outlet 114 and the second air outlet 115 was obtained. 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)]]> ratio of air flow rate 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] As shown in Table 1, 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 and 23.4, indicating that the heat dissipation effect of the air supply device 100 is good.

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

[0073] For example, the distance S2 between the heating element and the flow divider cone 150 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc., and can be reasonably selected according to actual needs, without being specifically limited here. By setting the above distance, the flow divider cone 150 can ensure the flow distribution effect of warm air, while ensuring the overall structure is compact and reducing the size 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, which includes a screw 171, a connecting rod 172, a slider 173, and a guide groove 174. The screw 171 is rotatably disposed within the housing 110. One end of the connecting rod 172 is threadedly connected to the screw 171, and the other end is connected to the slider 173. The guide groove 174 is fixed within the housing 110. The slider 173 slides within the guide groove 174, and the end of the slider 173 away from the connecting rod 172 is connected to the diverter cone 150.

[0075] Specifically, the bottom of the screw 171 can be rotatably mounted inside the housing 110 via a bearing or bushing. The top plate extends out of the housing 110 and is equipped with a knob structure, so that the screw 171 can be rotated by turning the knob with external force. The guide groove 174 can be defined by two oppositely arranged rods. 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 via a slider 173. When the screw 171 rotates, the connecting rod 172 cannot rotate with the screw 171, but 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 flow divider cone 150 can also be adjusted up and down using other driving methods. For example, a hydraulic cylinder, a pneumatic cylinder, or other telescopic workpiece can be used to directly control the up and down movement of the flow divider cone 150, or the position adjustment of the flow divider cone 150 can be achieved indirectly through gear transmission, chain transmission, etc. This embodiment does not make specific limitations.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
