Abstract
Description
Technical Field
[0001] This invention relates to the field of ventilation and air exchange equipment technology, and in particular to a heating and air supply device. Background Technology
[0002] Typical heating and ventilation systems are equipped with multiple air outlets and corresponding heaters to heat multiple areas or spaces within a room. For example... Figure 1 As shown, a ceiling-mounted heater includes a first air outlet 101, a second air outlet 102, a heating element 103 disposed upstream of the first air outlet 101 and the second air outlet 102, and a first rotating damper 104 and a second rotating damper 105 disposed upstream of the heating element 103. The opening and closing of the first air outlet 101 or the second air outlet 102 is controlled by rotating the dampers in the air duct. When the first rotating damper 104 closes the first air outlet 101 and the second rotating damper 105 opens the second air outlet 102, warm air can be delivered into the room through the second air outlet 102. When the first rotating damper 104 opens the first air outlet 101 and the second rotating damper 105 closes the second air outlet 102, warm air can be delivered into the room through the first air outlet 101. When the first rotary damper 104 opens the first air outlet 101 and the second rotary damper 105 opens the second air outlet 102, warm air can be simultaneously delivered into the room through both the first air outlet 101 and the second air outlet 102. This allows for the separate supply of heating to multiple spaces or areas.
[0003] like Figure 1 The heating and ventilation device shown has multiple air outlets and corresponding heaters. To provide heating to multiple areas or spaces, heaters are installed at each of the air outlets. The overall heating power of the device is the sum of the power of each individual heater, and its maximum heating power is also the sum of the power of each individual heater. The maximum heating power of each air outlet is the maximum power of its corresponding heater, making it impossible to utilize the overall maximum heating power of the device to supply air to a specific area. Furthermore, when a user has a high heating demand for a particular area, the heating efficiency of that air outlet will also be limited by the power of the corresponding heater, making it impossible to flexibly adjust the heating power of each air outlet to meet the user's needs.

[0048] [First Embodiment]
[0049] This embodiment provides a heating and ventilation device, including: an air inlet for air intake; at least two air outlets for air exhaust; and a heating unit disposed upstream of the at least two air outlets. The heating unit includes: a heating unit for heating air; and a driving unit for moving the heating unit between the at least two air outlets. Through this design, the driving unit can move the heating unit to one or more of the at least two air outlets, thereby heating the air flowing through those outlets.

Figure 10 This is a schematic diagram of the heating section of the heating and ventilation device provided in the first embodiment of the present invention.
[0052] like Figures 2 to 10 As shown, this embodiment discloses a heating and air supply device 100, including a basket 110, an air inlet 115, a first air outlet 116, a second air outlet 117, a third air outlet 118, an air supply unit 120, and a third air outlet 118 and an air exchange unit 130 for ventilation.
[0053] The housing 110 forms the outline of the heating and ventilation device 100 and is a hollow polygonal shape. In this embodiment, the housing 110 is a hollow cuboid shape, including a bottom surface, a top surface opposite the bottom surface, and side surfaces connecting the bottom surface and the top surface. The side surfaces include opposing first side surface 111 and second side surface 112, and opposing third side surface 113 and fourth side surface 114. In this embodiment, the heating and ventilation device 100 is installed on the ceiling with its bottom surface facing the ground; therefore, the top surface is located above the bottom surface.
[0054] The air inlet 115 is an opening for air to enter the heating and ventilation device 100. In this embodiment, the air inlet 115 is located on the side of the housing 110, specifically, the air inlet 115 is an opening located on the third side 113 of the housing 110. Similarly, as long as air can be supplied to the heating and ventilation device 100, the air inlet 115 can also be located on the bottom or top surface of the housing 110, or other sides. Furthermore, the air inlet 115 can also be located on other components separate from the housing 110, such as a face shield.
[0055] The first air outlet 116 is an opening for air to be blown out. In this embodiment, the first air outlet 116 is located on the side of the basket 110, specifically on the first side 111 of the basket 110. Similarly, as long as air can be blown out of the heating and ventilation device 100, the first air outlet 116 can also be located on the bottom or top surface of the basket 110, or on other sides. Furthermore, the first air outlet 116 can also be located on other components separate from the basket 110 and connected to the basket 110 via pipes or the like.
[0056] The second air outlet 117 is an opening for air to be blown out. In this embodiment, the second air outlet 117 is located on the side of the basket 110, specifically on the surface of the basket 110 adjacent to or the same as the first air outlet 116. In this embodiment, the second air outlet 117 is located on the first side 111, adjacent to the first air outlet 116. Similarly, as long as air can be blown out of the heating and ventilation device 100, the second air outlet 117 can also be located on other surfaces of the basket 110. Furthermore, the second air outlet 117 can also be located on other components separate from the basket 110 and connected to the basket 110 via pipes or the like.
[0057] The third air outlet 118 is an opening for air to be blown out. In this embodiment, the third air outlet 118 is located on the side of the basket 110. Specifically, the third air outlet 118 is located on the second side 112 of the basket 110, opposite to the first air outlet 116 and the second air outlet 117. Similarly, as long as air can be blown out of the heating and ventilation device 100, the third air outlet 118 can also be located on other surfaces of the basket 110. Furthermore, the third air outlet 118 can also be located on other components separate from the basket 110 and connected to the basket 110 via pipes or the like.
[0058] The air supply unit 120 is used to supply air from the air inlet 115 to the first air outlet 116 or the second air outlet 117, or simultaneously to both the first air outlet 116 and the second air outlet 117. In this embodiment, the air supply unit 120 is disposed in the housing 110, connecting the air inlet 115 with the first air outlet 116 and the second air outlet 117. The air supply unit 120 includes a snail shell forming an air path for supplying air from the air inlet 115 to the first air outlet 116 and the second air outlet 117, fan blades disposed in the snail shell, and a motor for controlling the rotation of the fan blades. In this embodiment, the fan blades are centrifugal fan blades. The snail shell includes a snail shell top plate with a snail shell air inlet 115, a snail shell bottom plate disposed on the opposite side of the snail shell top plate, and a snail shell side plate connecting the snail shell top plate and the snail shell bottom plate. The snail shell's top plate, bottom plate, and side plates constitute the snail shell's air outlet. The snail shell also includes a tongue 121 located on the side plate, closest to the fan blades.
[0059] The ventilation unit 130 is used to supply air from the air inlet 115 to the third air outlet 118. In this embodiment, the ventilation unit 130 is disposed in the housing 110 and connects the air inlet 115 and the third air outlet 118. The ventilation unit 130 includes a snail shell forming an air path for supplying air from the air inlet 115 to the third air outlet, fan blades disposed in the snail shell, and a motor for controlling the rotation of the fan blades. In this embodiment, the fan blades are centrifugal fan blades. The snail shell includes a top plate with a snail shell air inlet 115, a bottom plate disposed on the opposite side of the top plate, and a side plate connecting the top plate and the bottom plate. The top plate, bottom plate, and side plate constitute the snail shell air outlet.
[0060] In this embodiment, the first air outlet 116 and the second air outlet 117 connect to the indoor environment, and the third air outlet 118 connects to the outdoor environment. That is, the heating and air supply device 100 connects to the indoor environment through the first air outlet 116 and the second air outlet 117, and to the outdoor environment through the third air outlet 118. Therefore, the air supply unit 120 connects to the indoor environment and supplies air to the indoor environment through the first air outlet 116 and the second air outlet 117. The ventilation unit 130 connects to the outdoor environment and exchanges air with the outdoor environment through the third air outlet 118.
[0061] In this embodiment, when the air supply unit 120 is activated, air enters the heating and air supply device 100 through the air inlet 115, passes sequentially through the air inlet 115 of the snail shell of the air supply unit 120 and the fan blades, and is then guided by the snail shell to be supplied to the room through the first air outlet 116 or the second air outlet 117, or simultaneously through the first air outlet 116 and the second air outlet 117. When the ventilation unit 130 is activated, air enters the heating and air supply device 100 through the air inlet 115, passes sequentially through the air inlet 115 of the snail shell of the ventilation unit 130 and the fan blades, and is then guided by the snail shell to be supplied to the outside through the third air outlet 118.
[0062] The heating and ventilation device 100 also includes a heating element 140.
[0063] The heating element 140 is located upstream of the first air outlet 116 and the second air outlet 117, and downstream of the fan blades of the air supply unit 120. In this embodiment, the heating element 140 is located downstream of the air outlet of the snail shell of the air supply unit 120.
[0064] The heating unit 140 includes a heating unit 141, a driving unit 142, and a transmission unit 143.
[0065] Heating unit 141 is used to heat the flowing air and is located upstream of the first air outlet 116 and the second air outlet 117. Heating unit 141 includes, but is not limited to, a PTC (Positive Temperature Coefficient) heater. Heating unit 141 has an air inlet surface 1411 facing upstream for air to flow in, and an air outlet surface 1412 facing downstream for air to be blown out. Air outlet surface 1412 is located on the side of heating unit 141 facing the first air outlet 116 and the second air outlet 117. In this embodiment, heating unit 141 is a PTC heater with a maximum power of 3000 watts.
[0066] In this embodiment, the first air outlet 116, the second air outlet 117, the third air outlet 118, and the air inlet surface 1411 and air outlet surface 1412 of the heating unit 141 are all parallel to the axial direction of the air supply unit 120 and the ventilation unit 130, that is, they are arranged parallel to the axial direction of the fan blades of the air supply unit 120 and the ventilation unit 130, which is beneficial to improving the space utilization rate inside the basket 110.
[0067] Preferably, the heating unit 141 has a curved surface protruding from the upstream side to the downstream side. That is, the heating unit 141 has a curved surface with its center located on the upstream side. In this embodiment, both the air outlet surface 1412 and the air inlet surface 1411 of the heating unit 141 are curved surfaces protruding downstream, as shown in the example. Figures 3 to 5Viewed vertically from the perspective shown, the heating unit 141 has an arc shape that curves and protrudes downstream. Similarly, the heating unit 141 may also have only the air outlet surface 1412 or the air inlet surface 1411 set as curved surfaces.
[0068] The drive unit 142 is used to control the movement of the heating unit 141 between the first air outlet 116 and the second air outlet 117. The drive unit 142 includes, but is not limited to, a stepper motor. The drive unit 142 is located upstream of the heating unit 141, and controls the heating unit 141 to move back and forth between the first air outlet 116 and the second air outlet 117. In this embodiment, the axial direction of the drive unit 142, for example, the extension direction of the output shaft of the stepper motor, is parallel to the plane where the first air outlet 116 and the second air outlet 117 are located, i.e., the side of the housing 110.
[0069] The transmission unit 143 is used to connect the heating unit 141 and the drive unit 142. In this embodiment, the transmission unit 143 is located in the radial direction of the drive unit 142. The radial direction refers to the direction from the center of the drive unit 142's rotating shaft, such as the output shaft of a stepper motor, outwards along the radius. That is, the transmission unit 143 extends from the outer periphery of the drive unit 142 to the outermost periphery to connect with the heating unit 141. Driven by the drive unit 142, the heating unit 141 can perform circular motion between the first air outlet 116 and the second air outlet 117 with the drive unit 142 as the center and the transmission unit 143 as the radius, thereby heating the air at the first air outlet 116 and / or the second air outlet 117.
[0070] In this embodiment, the transmission unit 143 extends from the outer periphery of the drive unit 142 to a more outer periphery and is connected to the heating unit 141, so that the heating unit 141, transmission unit 143, and drive unit 142 form a fan-shaped orthographic projection on the bottom surface of the housing 110. Specifically, the transmission unit 143 is a flat plate extending from the outer periphery of the drive unit 142 to a more outer periphery. Similarly, as long as it can connect to the heating unit 141 and make it rotate around the drive unit 142, the transmission unit 143 can also be a long strip extending from the outer periphery of the drive unit 142 to a more outer periphery.
[0071] In this embodiment, the heating unit 141 moves between the first air outlet 116 and the second air outlet 117, including but not limited to the following states: the air outlet surface 1412 of the heating unit 141 is completely opposite to the first air outlet 116; or the air outlet surface 1412 of the heating unit 141 is completely opposite to the second air outlet 117; or a portion of the air outlet surface 1412 of the heating unit 141 is opposite to the first air outlet 116, while the other portion is opposite to the second air outlet 117.
[0072] The heating and ventilation device 100 also includes a first air duct and a second air duct.
[0073] The first air path connects the air inlet 115 and the first air outlet 116, guiding air from the air inlet 115 to the first air outlet 116. In this embodiment, the first air outlet 116 is an air outlet near the tongue 121 of the snail shell of the air supply unit 120. The air inlet 115, the snail shell of the air supply unit 120, and the first air outlet 116 form the first air path.
[0074] The second air path connects the air inlet 115 and the second air outlet 117, guiding air from the air inlet 115 to the second air outlet 117. In this embodiment, the second air outlet 117 is an air outlet located further away from the snail shell tongue 121 of the air supply unit 120 than the first air outlet 116. The air inlet 115, the snail shell of the air supply unit 120, and the second air outlet 117 form the second air path.
[0075] The heating and air supply device 100 also includes an air duct partition 150.
[0076] An airflow partition 150 is disposed between the first air outlet 116 and the second air outlet 117, protruding from the junction of the first and second airflow paths to separate them. The airflow partition 150 forms part of the airflow wall of the first and second airflow paths. In this embodiment, the airflow partition 150 protrudes upstream of the first and second air outlets 116 and 117, forming a flat plate protruding from the bottom to the top surface of the housing 110. In this embodiment, the airflow partition 150 includes a front airflow partition plate 151 and a rear airflow partition plate 152. The front airflow partition plate 151 is disposed downstream of the heating unit 141, separating the first air outlet 116 and the second air outlet 117. The rear airflow partition plate 152 is disposed upstream of the heating unit 141 and located between the heating unit 141 and the drive unit 142. There is a space 154 between the front air duct partition 151 and the rear air duct partition 152 for the heating unit 141 to pass through. That is, when viewed from the top and bottom surfaces of the housing 110, at least a portion of the air duct partition 150 is located downstream of the heating unit 141, and at least a portion is located between the heating unit 141 and the drive unit 142.
[0077] The air duct partition 150 is also provided with a through hole 153 for the transmission unit 143 of the heating unit 140 to pass through. Furthermore, in this embodiment, a sealing element is provided between the through hole 153 and the transmission unit 143. The sealing element includes, but is not limited to, rubber, sponge, etc.
[0078] In addition, the heating and ventilation device 100 also includes an air path switching unit 160.
[0079] The airflow switching unit 160 is located upstream of the first air outlet 116 and the second air outlet 117 and downstream of the air inlet 115, and upstream of the heating unit 140. It is used to control the on / off state of the first and second airflow paths, or to control the on / off state of either the first or second airflow path separately. The airflow switching unit 160 includes a first guide vane 161 and a second guide vane 162 for blocking the conduction of either the first or second airflow path.
[0080] The first air guide vane 161 is flat, with its surface intersecting the bottom surface of the housing 110. It has a front end near the heating unit 141 and an end end opposite the front end, away from the heating unit 141. In this embodiment, the first air guide vane 161 is disposed between the fan blades of the heating unit 140 and the air supply unit 120, and is located upstream of the drive unit 142. The front end of the first air guide vane 161 is connected to the drive unit 142 of the heating unit 140, and the drive unit 142 controls the first air guide vane 161 to move between the first air outlet 116 and the second air outlet 117. In this embodiment, the length of the first air guide vane 161 is less than the distance between the air supply unit 120 and the drive unit 142. The length of the first air guide vane 161 refers to the distance between its front end and its end end. The distance between the air supply unit 120 and the drive unit 142 refers to the straight-line distance between the outer periphery of the fan blades of the air supply unit 120 and the outer periphery of the drive unit 142, to avoid the first air guide vane 161 colliding with the air supply unit 120 when it moves with the drive unit 142. In this embodiment, the front end of the first air guide vane 161 is integrally formed with the transmission unit 143 and then connected to the drive unit 142 together with the transmission unit 143. Similarly, the front end of the first air guide vane 161 can also be separately set from the transmission unit 143 and connected to the drive unit 142 respectively.
[0081] The second air guide vane 162 is flat, with its surface intersecting the bottom surface of the housing 110. It has a front end connected to the first air guide vane 161 and an end end located opposite the front end. The front end of the second air guide vane 162 is connected to the end end of the first air guide vane 161. This connection can be direct or indirect. A direct connection between the first air guide vane 161 and the second air guide vane 162 means that the front end of the second air guide vane 162 and the end end of the first air guide vane 161 are integrally formed. However, the connection point between the front end of the second air guide vane 162 and the end end of the first air guide vane 161 is designed to be thinner or elastic or flexible, allowing for a movable connection between the second air guide vane 162 and the first air guide vane 161, enabling the second air guide vane 162 to rotate around the end end of the first air guide vane 161. In this embodiment, the length of the second air guide vane 162 is less than the length of the first air guide vane 161.
[0082] In this embodiment, the airflow switching unit 160 further includes a connecting unit 163. The connecting unit 163 is disposed within the housing 110 and is used to connect the first air guide vane 161 and the second air guide vane 162, thereby movably connecting the first air guide vane 161 and the second air guide vane 162. Specifically, the second air guide vane 162 can rotate around the connecting unit 163, that is, the end of the second air guide vane 162 moves in a circular motion around the connecting unit 163. In this embodiment, the connecting unit 163 includes a rotating shaft. The end of the first air guide vane 161 has a connecting hole for the rotating shaft to pass through, and the front end of the second air guide vane 162 has a connecting hole for the rotating shaft to pass through. The rotating shaft of the connecting unit 163 passes through the connecting holes of the first air guide vane 161 and the second air guide vane 162, thereby movably connecting the first air guide vane 161 and the second air guide vane 162.
[0083] In this embodiment, the air path switching unit 160 may further include a guide unit 164.
[0084] The guiding unit 164 is used to guide the second air guide vane 162 to move between the first air path and the second air path. That is, under the guidance of the guiding unit 164, the second air guide vane 162 can move from the first air path to the second air path, or from the second air path to the first air path, or from the first air path or the second air path to the intersection of the first air path and the second air path. The intersection of the first air path and the second air path includes the adjacent part of the first air path and the vicinity of the adjacent part, that is, the position on the first air path near the second air path and the position on the second air path near the first air path.
[0085] The guide unit 164 is a guide rail that engages with the end of the second air guide vane 162. Under the action of external force, the end of the guide unit 164 can slide along the guide rail. In this embodiment, the guide rail is provided on the top surface of the basket 110. Specifically, the guide rail is provided on the top surface of the snail shell of the air supply unit 120, and the first air guide vane 161 and the second air guide vane 162 are provided inside the snail shell of the air supply unit 120. Similarly, the guide rail can also be provided on the bottom surface of the basket 110 or other locations.
[0086] The guide unit 164 includes a first guide rail 1641 and a second guide rail 1642.
[0087] The first guide rail 1641 is disposed in the first air passage, including one end located outside the first air passage and the other end located at the junction of the first air passage and the second air passage. The outside of the first air passage refers to the side of the first air passage closer to the side of the basket 110 and farther away from the second air passage. In this embodiment, one end of the first guide rail 1641 is connected to the tongue 121 of the snail shell and is in a straight line shape inclined from the tongue 121 towards the drive unit 142. Furthermore, the end of the first guide rail 1641 near the drive unit 142 is located between the connecting unit 163 and the drive unit 142.
[0088] The second guide rail 1642 is disposed in the second air passage, including one end located on the outer side of the second air passage and the other end located at the junction of the first air passage and the second air passage. The outer side of the second air passage refers to the side of the second air passage closer to the side of the basket 110 and farther away from the first air passage. In this embodiment, one end of the second guide rail 1642 is connected to the opposite side of the snail shell tongue 121 and is arc-shaped, protruding from the downstream side to the upstream side of the heating unit 141. Viewed from the bottom plate of the snail shell to the top plate of the snail shell, the guide unit 164 is approximately in the shape of the number 2, that is, the first guide rail 1641 and the second guide rail 1642 are combined to form an approximately in the shape of the number 2.
[0089] In this embodiment, the first guide rail 1641 and the second guide rail 1642 are grooves provided on the top surface of the snail shell. The end of the second air guide 162 is engaged in the groove.
[0090] The other end of the first guide rail 1641 located at the intersection of the first air path and the second air path is connected to or overlaps with the other end of the second guide rail 1642 located at the intersection of the first air path and the second air path, so that the second air guide vane 162 can slide directly from the first guide rail 1641 to the second guide rail 1642, or slide directly from the second guide rail 1642 to the first guide rail 1641.
[0091] The specific implementation of the first embodiment will be described below.
[0092] When the heating and ventilation device 100 is running and the ventilation unit 120 is running, air enters the heating and ventilation device 100 from the air inlet 115 under the action of the ventilation unit 120. After passing through the snail shell air inlet 115, fan blades, air path switching part 160 and heating part 140 of the ventilation unit 120 in sequence, it is blown into the room to the first air outlet 116 or the second air outlet 117, or simultaneously to the first air outlet 116 and the second air outlet 117.
[0093] like Figure 3As shown, since the heating unit 141 of the heating section 140 can move between the first air outlet 116 and the second air outlet 117, when the heating unit 141 moves to the upstream side of the first air outlet 116 and the air outlet surface 1412 of the heating unit 141 is completely opposite to the first air outlet 116, that is, when the heating unit 141 is away from the upstream side of the second air outlet 117, the heating and air supply device 100 can deliver warm air to the first air outlet 116 and cool air to the second air outlet 117 at the same time. This achieves separate air supply to multiple spaces or multiple areas. In addition, when a user needs to deliver warm air through the first air outlet 116 to quickly heat up the corresponding indoor space, the heating unit 141 moves to the first air outlet 116 and its air outlet surface 1412 is completely opposite to the first air outlet 116, and the heating unit 141 is controlled to heat at maximum power. Thus, the maximum heating power of the heating and air supply device 100 can be fully utilized.
[0094] like Figure 4 As shown, similarly, when the heating unit 141 moves to the upstream side of the second air outlet 117, and the air outlet surface 1412 of the heating unit 141 is completely opposite to the second air outlet 117, that is, when the heating unit 141 is away from the upstream side of the first air outlet 116, the heating and air supply device 100 can simultaneously deliver warm air to the second air outlet 117 and cool air to the first air outlet 116, thereby achieving separate air supply to multiple spaces or areas. Furthermore, when a user needs to quickly heat the corresponding indoor space by delivering warm air through the second air outlet 117, the heating unit 141 moves to the second air outlet 117, with its air outlet surface 1412 completely opposite to the second air outlet 117, and the heating unit 141 is controlled to heat at maximum power, thus fully utilizing the maximum heating power of the heating and air supply device 100.
[0095] like Figure 5 As shown, when the user needs warm air to be delivered from both the first air outlet 116 and the second air outlet 117 simultaneously, the heating unit 141 is moved to the junction of the first air outlet 116 and the second air outlet 117. That is, a portion of the air outlet surface 1412 of the heating unit 141 faces the first air outlet 116, and another portion faces the second air outlet 117. Specifically, the heating power of the heating unit 141 or the area of the air outlet surface 1412 facing the first air outlet 116 and the second air outlet 117 is controlled according to the user's needs to adjust the temperature of the warm air blown out from the first air outlet 116 and the second air outlet 117. For example, if the heating power of the heating unit 141 remains unchanged, and the area ratio of the air outlet surface 1412 of the heating unit 141 to the area ratio of the first air outlet 116 and the second air outlet 117 is controlled to be 2:1, then the temperature ratio of the air supplied by the first air outlet 116 and the second air outlet 117 can be adjusted, thereby making the air supply temperature of the heating and air supply device 100 more flexible.
[0096] Furthermore, since the heating unit 140 includes a transmission unit 143 and a drive unit 142, and the heating unit 141 is connected to the drive unit 142 via the transmission unit 143, the heating unit 141 moves in a circular motion around the drive unit 142. As a result, the movement of the heating unit 141 can be made smoother.
[0097] When air is blown from the fan blades of the air supply unit 120 to the first air outlet 116 and the second air outlet 117, the air is blown to the first air outlet 116 or the second air outlet 117 under the action of the air path switching part 160 provided on the upstream side of the heating part 140.
[0098] When the drive unit 142 of the heating unit 140 rotates from the second air outlet 117 side to the first air outlet 116 side, the transmission unit 143 also rotates from the second air outlet 117 side to the first air outlet 116 side. Under the action of the transmission unit 143, the heating unit 141 rotates from the second air outlet 117 side to the first air outlet 116 side. Since the front end of the first air guide vane 161 of the air path switching unit 160 is connected to the upstream side of the drive unit 142, when the drive unit 142 rotates from the second air outlet 117 side to the first air outlet 116 side, the front end of the first air guide vane 161 rotates with the drive unit 142 from the outer periphery of the first air outlet 116 side to the second air outlet 117 side. The end of the first air guide vane 161 rotates around the drive unit 142. When the air outlet surface 1412 of the heating unit 141 is completely opposite to the first air outlet 116, the first air guide 161 moves to the side of the second air outlet 117 and blocks a part of the second air outlet 117.
[0099] Meanwhile, since the front end of the second guide vane 162 is movably connected to the end of the first guide vane 161 through the connecting unit 163, when the end of the first guide vane 161 makes a circular motion around the driving unit 142, the second guide vane 162 will also be driven.
[0100] Since the airflow switching unit 160 also includes a guide unit 164 that engages with the end of the second airflow guide 162, and one end of the first guide rail 1641 is located outside the first airflow path and the other end is located at the intersection of the first airflow path and the second airflow path, and one end of the second guide rail 1642 is located outside the second airflow path and the other end is located at the intersection of the first airflow path and the second airflow path, when the front end of the second airflow guide 162 is driven by the first airflow guide 161, for example, when the first airflow guide 161 moves from the side of the first air outlet 116 to the side of the second air outlet 117, that is, from the side of the first airflow path to the side of the second airflow path, the front end of the second airflow guide 162 will also move from the side of the first airflow path to the side of the second airflow path, thereby driving the end of the second airflow guide 162 to move from the side of the first airflow path to the side of the second airflow path. Since the end of the second guide vane 162 engages with both the first and second guide rails 1641 and 1642, when the second guide vane 162 moves from the first airflow path to the second airflow path, its end, guided by the first guide rail 1641, first moves along the first guide rail 1641 from the tongue 121 towards the drive unit 142. When the end of the second guide vane 162 reaches the junction of the first and second guide rails 1641, it is located downstream of the connecting unit 163. The end of the second guide vane 162 then moves from the first guide rail 1641 to the second guide rail 1642, continuing along the second guide rail 1642 towards the second air outlet 117. When the end of the second guide vane 162 moves along the second guide rail 1642 to the opposite side of the snail shell tongue 121, it is located upstream of the connecting unit 163. At this time, the second air guide 162 contacts the side wall of the snail shell, and the first air guide 161 and the second air guide 162 completely block the second air outlet 117, that is, the second air path is cut off.
[0101] Furthermore, an air duct partition 150 is provided between the first and second air ducts, and a through hole 153 is provided on the air duct partition 150. When the heating unit 141 moves between the first air outlet 116 and the second air outlet 117, the transmission unit 143 passes through the through hole 153 and moves relative to the through hole 153. When the air outlet surface 1412 of the heating unit 141 is completely opposite to the first air outlet 116 or the second air outlet 117, the transmission unit 143 seals the through hole 153.
[0102] When air is blown from the fan blades of the air supply unit 120 toward the first air outlet 116 and the second air outlet 117, the second air outlet 117 is blocked by the first guide vane 161 and the second guide vane 162 included in the air path switching part 160. Therefore, the air originally blown toward the second air outlet 117 is guided by the air path switching part 160 and blown sequentially toward the first air path, the heating unit 141, and the first air outlet 116. Furthermore, since the transmission unit 143 seals the through hole 153 at this time, it can prevent air in the first air path from being blown into the second air path through the through hole 153 of the air path partition part 150.
[0103] Therefore, while ensuring that the heating unit 141 can move smoothly between the first air outlet 116 and the second air outlet 117, it can prevent air from being blown out from the through hole 153, which could lead to air leakage or even noise.
[0104] Similarly, when the heating unit 141 moves from the first air outlet 116 side to the second air outlet 117 side, the first air guide vane 161 and the second air guide vane 162 move from the second air outlet 117 side to the first air outlet 116 side. When the air outlet surface 1412 of the heating unit 141 is completely opposite to the second air outlet 117, the transmission unit 143 seals the through hole 153. The first air guide vane 161 and the second air guide vane 162 completely cover the first air outlet 116 and are inclined from the first air outlet 116 side to the second air outlet 117 side. Therefore, when air is blown from the fan blades of the air supply unit 120 towards the first air outlet 116 and the second air outlet 117, since the first air outlet 116 is blocked by the first guide vane 161 and the second guide vane 162 included in the air path switching part 160, the air originally blown towards the first air outlet 116 is guided by the air path switching part 160 to be blown sequentially towards the second air path, the heating unit 141, and the second air outlet 117. Furthermore, since the transmission unit 143 seals the through hole 153 at this time, it can prevent air in the second air path from being blown out through the through hole 153 of the air path partition part 150 into the second air path.
[0105] When the heating unit 141 moves to the junction of the first air outlet 116 and the second air outlet 117, the drive unit 142 controls the heating unit 141 to rotate to the junction of the first air outlet 116 and the second air outlet 117. At this time, a part of the air outlet surface 1412 of the heating unit 141 is opposite to the first air outlet 116, and another part is opposite to the second air outlet 117. Furthermore, the first air guide vane 161, driven by the drive unit 142, rotates to the junction of the first air outlet 116 and the second air outlet 117. Guided by the connecting unit 163 and the guiding unit 164, the end of the second air guide vane 162 moves from one side of the first air outlet 116 or the second air outlet 117 to the junction of the first air outlet 116 and the second air outlet 117. At this time, the end of the second guide vane 162 is located at the junction of the first guide rail 1641 and the second guide rail 1642, and the first guide vane 161 and the second guide vane 162 are in a folded state. The end of the second guide vane 162 is located downstream of the end of the first guide vane 161, and there is a certain distance between the end of the first guide vane 161 and the fan blade of the air supply unit 120.
[0106] Thus, the first air path and the second air path are connected between the end of the first guide vane 161 and the fan blades of the air supply unit 120. When air is blown from the fan blades of the air supply unit 120 towards the first air outlet 116 and the second air outlet 117, and reaches the end of the first guide vane 161, it will be guided by the first guide vane 161 and the second guide vane 162, and divided into two streams of air that are blown towards the first air path and the second air path respectively. When air enters the first air path and is blown towards the first air outlet 116, since a part of the air outlet surface 1412 of the heating unit 141 is opposite to the first air outlet 116, at least a part of the air entering the first air path will also be blown towards the heating unit 141, and after being heated by the heating unit 141, it will be blown into the room through the first air outlet 116. Similarly, when air enters the second air duct and blows toward the second air outlet 117, since a portion of the air outlet surface 1412 of the heating unit 141 is opposite to the second air outlet 117, at least a portion of the air entering the second air duct will also be blown toward the heating unit 141, and after being heated by the heating unit 141, it will be blown into the room through the second air outlet 117.
[0107] In addition, since the length of the second air guide 162 is less than the length of the first air guide 161, when the second air guide 162 moves to the junction of the first air outlet 116 and the second air outlet 117, the end of the second air guide 162 is located between the end and the front end of the first air guide 161. This can prevent the second air guide 162 from being unable to fold with the first air guide 161 due to interference between the second air guide 162 and the drive unit 142, thereby reducing the airflow area and causing problems such as reduced air volume or noise.
[0108] Therefore, the heating unit 141 can move between the first air outlet 116 and the second air outlet 117, and the air temperature blown out from the first air outlet 116 and the second air outlet 117 can be flexibly controlled by controlling the relative areas of the heating unit 141 with the first air outlet 116 and the second air outlet 117. At the same time, the movement of the first air guide vane 161 and the second air guide vane 162 can be controlled simultaneously by a single drive unit 142, thereby meeting various air supply needs of users while saving costs.
[0109] [Second Embodiment]
[0110] The second embodiment of the present invention will be described below, wherein the parts that are the same as those in the first embodiment will not be repeated.
[0111] Figure 11 This is a schematic diagram of the internal structure of the heating and ventilation device provided in the second embodiment of the present invention. Figure 11 As shown, in this embodiment, the first guide rail 1641 includes a first outer guide rail 1641a and a first inner guide rail 1641b. The first outer guide rail 1641a is an arc-shaped section protruding from one end of the first guide rail 1641 to the other end, from the downstream side to the upstream side of the first air passage. The first inner guide rail 1641b is connected to the first outer guide rail 1641a and is an approximately straight section extending from the outer periphery to the inner periphery of the first air passage. Figure 11 As shown, in the installed state, when viewed from above and below the housing 110, the first guide rail 1641 has an approximate "2" shape.
[0112] Similarly, the second guide rail 1642 includes a second outer guide rail 1642a and a second inner guide rail 1642b. The second outer guide rail 1642a is an arc-shaped section protruding from one end of the second guide rail 1642 to the other end, from the downstream side to the upstream side of the second air passage. The second inner guide rail 1642b is connected to the second outer guide rail 1642a and is an approximately straight section extending from the outer periphery to the inner periphery of the second air passage. Figure 11 As shown, in the installed state, when viewed from above and below the housing 110, the second guide rail 1642 forms an approximately inverted "2" shape that is symmetrical about the centerline with the first guide rail 1641.
[0113] Since the end of the second guide vane 162 engages with both the first guide rail 1641 and the second guide rail 1642, when the second guide vane 162 moves from the first air passage side to the second air passage side, its end, guided by the first guide rail 1641, first rotates clockwise around the connecting unit 163 along the first outer guide rail 1641a. When the end of the second guide vane 162 moves along the first outer guide rail 1641a to the point where it connects with the first inner guide rail 1641b, the end of the second guide vane 162 is located downstream of the connecting unit 163. As the front end of the second guide vane 162 continues to move towards the second air outlet 117 along with the first guide vane 161, the end of the second guide vane 162 moves along the first inner guide rail 1641b, and, guided by the first inner guide rail 1641b, the end of the second guide vane 162 continues to move towards the second air outlet 117. When the end of the second guide vane 162 moves to the junction of the first inner guide rail 1641b and the second inner guide rail 1642b, the second guide vane 162 coincides with or nearly coincides with the first guide vane 161, and the end of the second guide vane 162 is located downstream of the end of the first guide vane 161. As the second guide vane 162 continues to move along the second guide rail 1642, the end of the second guide vane 162 first moves along the second inner guide rail 1642b, and then rotates along the second outer guide rail 1642a towards the outer periphery of the second air passage. The end of the second guide vane 162 is first located downstream of the end of the first guide vane 161, and then moves upstream of the connecting unit 163. When the air outlet surface 1412 of the heating unit 141 is completely opposite to the first air outlet 116, the first air guide vane 161 moves to the upstream side of the second air outlet 117, while the end of the second air guide vane 162 is located upstream of the connecting unit 163 and contacts the side wall of the snail shell of the air supply unit 120. At this time, the first air guide vane 161 and the second air guide vane 162 completely block the second air outlet 117 and tilt from the side of the second air outlet 117 towards the side of the first air outlet 116, that is, the second air path is blocked.
[0114] [Third Embodiment]
[0115] The third embodiment of the present invention will be described below, wherein the parts that are the same as those in the first and second embodiments will not be repeated.
[0116] Figure 12 This is a schematic diagram of the structure of the heating and air supply device provided in the third embodiment of the present invention, in which the first air path and the second air path are simultaneously connected. Figure 13 This is a schematic diagram of the structure of the heating and air supply device provided in the third embodiment of the present invention, showing the first air path being open and the second air path being closed. Figure 14 This is a schematic diagram of the structure of the heating and air supply device provided in the third embodiment of the present invention, showing the second air path opening and the first air path closing.
[0117] like Figures 12 to 14As shown, in this embodiment, the air path switching unit 160 includes a first air guide vane 161 and a second air guide vane 162, as well as a first air guide driving unit 1611 driving unit 142 and a second air guide driving unit 1621 driving unit 142 that drive the first air guide vane 161 and the second air guide vane 162 respectively.
[0118] The first air guide vane 161 is disposed in the first air passage, located upstream of the first air outlet 116 and the heating unit 141. The first air guide vane 161 is flat, with its surface intersecting the bottom surface of the housing 110, and has a front end away from the heating unit 141, and an end located on the opposite side of the front end, close to the heating unit 141.
[0119] The first air guide drive unit 1611 and drive unit 142 are located outside the first air passage. In this embodiment, the first air guide drive unit 1611 and drive unit 142 are connected to the front end of the first air guide vane 161. The end of the first air guide vane 161 moves in a circular motion around the first air guide drive unit 1611 and drive unit 142.
[0120] The second air guide vane 162 is disposed in the second air passage, located upstream of the second air outlet 117 and the heating unit 141. The second air guide vane 162 is flat, with its surface intersecting the bottom surface of the housing 110. It has a front end away from the heating unit 141 and an end located on the opposite side of the front end, close to the heating unit 141.
[0121] The second air guide drive unit 1621 and drive unit 142 are located outside the second air passage. In this embodiment, the second air guide drive unit 1621 and drive unit 142 are connected to the front end of the second air guide vane 162. The end of the second air guide vane 162 moves in a circular motion around the second air guide drive unit 1621 and drive unit 142.
[0122] When the control heating unit 141 moves to the first air outlet 116, and the air outlet surface 1412 of the heating unit 141 is completely opposite to the first air outlet 116, the first air guide drive unit 1611 drives the first air guide vane 161 to rotate to the outer periphery of the first air path. At this time, the first air guide vane 161 does not block the first air outlet 116.
[0123] At the same time, the second air guide drive unit 1621 and the drive unit 142 control the second air guide vane 162 to rotate towards the inner circumference of the second air path. At this time, the second air guide vane 162 blocks the second air outlet 117 and tilts from the upstream side towards the drive unit 142 of the heating part 140.
[0124] When air is blown from the fan blades of the air supply unit 120 towards the first air outlet 116 and the second air outlet 117, the air that was originally going to the second air path is guided by the second air guide 162 to the first air path because the second air outlet 117 is blocked by the second air guide 162. At the same time, since the heating unit 141 is completely opposite to the first air outlet 116 and the first air guide 161 does not block the first air outlet 116, it is possible to control the heating and air supply device to deliver warm air to the first air outlet 116.
[0125] In addition, if the second air guide 162 does not block the second air outlet 117 at this time, the heating and air supply device can be controlled to send cool air to the second air outlet 117.
[0126] Therefore, the temperature of the air supplied from the first air outlet 116 and the second air outlet 117 can be flexibly controlled.
[0127] Similarly, when the heating unit 141 moves to the second air outlet 117, the first air guide vane 161 blocks the first air outlet 116 and tilts from the upstream side towards the drive unit 142 of the heating section 140, while the second air guide vane 162 does not block the second air outlet 117. Therefore, when air is blown from the fan blades of the air supply unit 120 towards both the first and second air outlets 116 and 117, the air originally intended for the first air path is guided by the first air guide vane 161 and blown towards the second air path because the first air outlet 116 is blocked. Furthermore, since the heating unit 141 is completely opposite to the second air outlet 117, and the second air guide vane 162 does not block the second air outlet 117, it is possible to control the heating and air supply device to deliver warm air to the second air outlet 117.
[0128] In addition, if the first air guide vane 161 does not block the first air outlet 116 at this time, the heating and air supply device can be controlled to send cool air to the first air outlet 116.
[0129] When the heating unit 141 moves to the junction of the first air outlet 116 and the second air outlet 117, both the first air guide vane 161 and the second air guide vane 162 rotate towards the outer periphery of the first and second air paths. At this time, the first air guide vane 161 controls the opening of the first air path, and the second air guide vane 162 controls the opening of the second air path. When air is blown from the fan blades of the air supply unit 120 towards the first air outlet 116 and the second air outlet 117, it can be blown into the first and second air paths respectively. A portion of the air in the first air path blows towards the heating unit 141, and a portion of the air in the second air path blows towards the heating unit 141, thereby delivering warm air to the first air outlet 116 and the second air outlet 117 respectively.
[0130] [Fourth Embodiment]
[0131] The fourth embodiment will be described below, and the parts that are the same as those in the first embodiment or the second and third embodiments will not be repeated.
[0132] In this embodiment, the heating unit 140 further includes a transmission unit 143 that connects the heating unit 141 and the driving unit 142.
[0133] In this embodiment, the transmission unit 143 is located in the axial direction of the drive unit 142. That is, in the installed state of the heating and air supply device, the transmission unit 143 is located below the drive unit 142 and above or below the heating unit 141. In this embodiment, the drive unit 142 is located above the heating unit 141, and the transmission unit 143 is located between the drive unit 142 and the heating unit 141.
[0134] Thus, driven by the transmission unit 143, the heating unit 141 can move relative to the drive unit 142 between the first air outlet 116 and the second air outlet 117, thereby heating the air in the first air path and / or the second air path.
