Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning indoor unit and an air conditioner. Background Art

[0002] Common floor-standing air conditioners all use a single cross-flow impeller or a single centrifugal impeller. The high-speed rotation of the impeller generates negative pressure, thereby driving the flow of gas, which is then sent out from the air outlet of the air conditioner through the heat exchanger, fan duct, and air guide mechanism. Since the air flow blown out of the air outlet of the floor-standing air conditioner is in a single form, it is impossible to form effective gas convection in the room, which causes the user to feel stuffy and affects the user experience. Long-distance air supply can be achieved by setting up a vortex ring generating device. However, the existing vortex ring generating device can usually only supply air in a fixed direction and cannot change the air supply direction, which leads to uneven indoor temperature distribution.

[0040] It should be noted that if any directional indications (such as up, down, left, right, front, back, etc.) are involved in the embodiments of the present invention, such directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly. In addition, the meaning of "and / or" appearing throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or solutions that meet both A and B.

[0041] The present invention proposes an air conditioner indoor unit that not only implements vortex ring air supply (i.e., air is blown out in a ring-shaped pattern), but also can change the air supply direction, thereby achieving a more uniform indoor temperature distribution and improving user comfort. The air conditioner indoor unit can be a floor-standing indoor unit or a wall-mounted indoor unit. The following description uses a floor-standing indoor unit as an example.

[0042] See also Figures 1 to 5 The present invention provides an air-conditioning indoor unit 100, comprising:

[0043] A housing 110 having a first air inlet 113 and a first air outlet 114 communicating with the first air inlet 113;

[0044] A vortex ring generating device 120 is installed on the housing 110. The vortex ring generating device 120 includes a wind tube 122, a flow collecting member 123 and a vortex ring generating portion 126. The wind tube 122 has a second air inlet 122a and a second air outlet 122b. The flow collecting member 123 is installed on the second air outlet 122b. The flow collecting member 123 is provided with an air supply port 1231 connected to the wind tube 122. The air flow area of ​​the air supply port 1231 is smaller than the air flow area of ​​the second air outlet 122b. The air supply port 1231 is connected to the room through the first air outlet 114. The vortex ring generating portion 126 is used to periodically drive the air flow to be blown out through the flow collecting member 123, or to periodically allow the air flow to pass through and be blown out through the flow collecting member 123.

[0045] The current collecting member 123 is rotatable relative to the housing 110 and has a rotation trajectory, and a center line of the rotation trajectory does not coincide with a center line of the air outlet 1231 .

[0046] In an embodiment of the present invention, the air conditioning indoor unit 100 has a first air outlet 114, which can realize vortex ring air supply. Specifically, the housing 110 includes a front panel 111 and two side panels 112 connecting the two sides of the front panel 111, and the first air outlet 114 is provided on the front panel 111. It is understandable that in order to realize various forms of air supply, the air conditioning indoor unit 100 may also have a second air outlet 122b (conventional air outlet), and the second air outlet 122b is provided on at least one of the side panels 112. A damper is installed at the second air outlet 122b, and the damper is used to open or close the second air outlet 122b.

[0047] See also Figure 1 and Figure 2 In one embodiment, the first air inlet 113 is disposed at the lower end of the housing 110, and the first air outlet 114 and the second air outlet 122b are both disposed at the upper end of the housing 110. An air duct is formed within the housing 110, connecting the first air inlet 113, the first air outlet 114, and the second air outlet 122b. A fan assembly 160 and a heat exchanger 150 are disposed within the air duct. Driven by the fan assembly 160, air enters the air duct from the first air inlet 113, undergoes heat exchange in the heat exchanger 150, and is then blown out from the first air outlet 114 and / or the second air outlet 122b, thereby achieving a more uniform indoor temperature distribution.

[0048] In an embodiment of the present invention, the vortex ring generating device 120 is capable of periodically blowing out a vortex ring airflow. The vortex ring generating device 120 can be installed inside or outside the housing 110, and is not specifically limited here. Specifically, a vortex ring air duct is formed in the vortex ring generating device 120. There are many ways to form the vortex ring air duct. For example, the vortex ring air duct can be formed by the cavity of the wind tube 122, or can be formed by the cavity of the wind tube 122 and other components (such as the vortex ring generating part 126). The vortex ring generating part 126 is installed in the vortex ring air duct to periodically drive the airflow to be blown out through the collecting part 123, or to periodically allow the airflow to pass through and be blown out through the collecting part 123.

[0049] The vortex ring generating unit 126 can have various structures. For example, in one embodiment, the vortex ring generating unit 126 includes a switch door and a second drive mechanism. The switch door is installed within the vortex ring air duct to block the airflow within the vortex ring air duct from flowing toward the flow collector 123. The second drive mechanism is connected to the switch door to periodically drive it open and close, thereby periodically allowing airflow to pass through and be blown out through the flow collector 123. Driven by the second drive mechanism, the switch door can rapidly open and close, resulting in pulsed airflow from the air outlet 1231, which provides the necessary conditions for vortex ring generation. When the switch door is closed, the air generated by the fan assembly 160 generates high pressure before the switch door. When the switch door is opened, the high-pressure airflow in front of the switch door rapidly passes through the switch door, and the flow collector 123 accelerates the high-pressure airflow, forming a vortex ring at the air outlet. It should be noted that the closure can be complete or partial, for example, closing 2 / 3, 4 / 5, 5 / 6, 9 / 10, etc.

[0050] The switch door can be a louver structure, a door panel structure, a fan structure, or the like. By periodically opening or closing the switch door structure, air with a certain pressure accumulated on one side of the switch door is rapidly directed toward the air outlet 1231, where it forms a vortex ring and is blown out. In one embodiment, the switch door includes multiple blades, and the vortex ring generating unit 126 also includes a transmission member that is connected to the multiple blades. A second drive device is connected to the transmission member to drive the transmission member to open or close the multiple blades. In this embodiment, the blade structure makes the opening and closing method of the switch door simpler, more reliable, and easier to implement. In one embodiment, the drive device is an electromagnet, and the transmission member includes a gear connected to a blade shaft, a rack connected to the electromagnet, and a transmission rod connected to the multiple blade shafts. The electromagnet pulse drives the rack, which in turn drives the gear to rotate, thereby driving the multiple blades to open or close. The electromagnet provides a pulse signal, which drives the rack to reciprocate, thereby driving the gear to rotate, thereby driving the multiple blades to open and close rapidly within a certain angle.

[0051] In another embodiment, the vortex ring generating unit 126 can also be a compression structure, or an air compressor, etc., so that the air flow can be periodically driven to be blown out through the collecting member 123. By periodically disturbing the air flow in the vortex ring air duct by the vortex ring generating unit 126, the air flow can be pushed out from the air supply port 1231 and have a certain flow rate. Due to the pressure difference between the central area and the peripheral area of ​​the air supply port 1231, the air flow at the side of the air supply port 1231 is supplemented to the edge of the air supply port 1231, so that a vortex ring airflow can be blown out at the air supply port 1231, and the diameter of the vortex ring airflow gradually increases, thereby achieving long-distance and wide-area air supply. Specifically, the vortex ring generating unit 126 includes a driving member (not shown) and a compression member (not shown). The compression member is installed in the vortex ring air duct. The driving member is connected to the compression member to periodically drive the compression member to squeeze the gas on the side of the vortex ring air duct close to the air supply port 1231 and blow the gas out through the air supply port 1231.

[0052] In this embodiment, the compression member can be a piston structure, a film structure, etc. When the compression member is a piston structure, the piston is sealed with the inner wall surface of the vortex ring air duct and can move relative to it. When the driving member drives the piston to move in the vortex ring air duct, it can compress the gas on the side of the vortex ring air duct close to the air supply port 1231, and then push the gas to form a vortex ring airflow and blow it out from the air supply port 1231. There can be many types of piston structures. For example, in one embodiment, the piston structure includes a push plate and a push rod connected to the push plate, and the push plate is movably connected to the inner wall surface of the vortex ring air duct. The driving member drives the push rod to drive the push plate to move in the vortex ring air duct. When the compression member is a film structure, the film structure is a flexible material or an elastic material, and the film structure is fixedly connected to the inner wall surface of the vortex ring air duct. By pushing and pulling the film structure, the gas on the side of the vortex ring air duct close to the air supply port 1231 can be periodically squeezed, thereby driving the airflow to form a vortex ring airflow and blow it out from the air supply port 1231.

[0053] In an embodiment of the present invention, the current collecting member 123 is installed at the second air outlet 122b, and the current collecting member 123 and the wind tube 122 can be integrally formed. Of course, the current collecting member 123 and the wind tube 122 can also be separately set. That is to say, the wind tube 122 can rotate with the current collecting member 123, or it can be fixed on the housing 110 without rotating, which will be described in detail below. There can be various structures of the current collecting member 123. For example, in one embodiment, the current collecting member 123 is cylindrical, and the current collecting member 123 is tapered along the direction of the wind tube 122 toward the air supply port 1231, so that the air flow area of ​​the air supply port 1231 can be smaller than the air flow area of ​​the first air outlet 114. In another embodiment, the current collecting member 123 can also be plate-shaped, and the air supply port 1231 is opened on the current collecting plate.

[0054] It is worth mentioning that the current collecting part 123 is rotatable relative to the housing 110 and has a rotation trajectory, and the center line of the rotation trajectory does not coincide with the center line of the air outlet 1231, so that when the current collecting part 123 is driven to rotate, the position of the air outlet 1231 can be continuously changed, thereby changing the air supply direction. Here, it needs to be explained that the rotation trajectory can be a circular trajectory, an elliptical trajectory, a spiral trajectory or a trajectory of other shapes, etc.; the center line of the air outlet 1231 refers to a straight line passing through the center of the air outlet 1231 and perpendicular to the air supply surface. The center line of the rotation trajectory does not coincide with the center line of the air outlet 1231 means that the center line of the rotation trajectory deviates from the center line of the air outlet 1231, that is, the center line of the rotation trajectory is different from the center line of the air outlet 1231. In this embodiment of the present invention, the flow collecting member 123 is connected to the indoor environment through the first air outlet 114, and the flow collecting member 123 can rotate relative to the housing 110 to change the air supply direction of the air outlet 1231. Therefore, the air supply area of ​​the first air outlet 114 must be larger than the air supply area of ​​the air outlet 1231. In addition, the shape of the air outlet 1231 is not specifically limited. For example, the shape of the air outlet 1231 can be triangular, circular, elliptical, square, or other special shapes.

[0055] The air conditioner indoor unit 100 of the present invention includes a vortex ring generating device 120 installed on a housing 110, the vortex ring generating device 120 includes a wind tube 122, a flow collecting member 123 and a vortex ring generating portion 126, the wind tube 122 has a second air inlet 122a and a second air outlet 122b; the flow collecting member 123 is installed at the second air outlet 122b, and the flow collecting member 123 is provided with an air supply port 1231 connected to the wind tube 122, and the air flow area of ​​the air supply port 1231 is The air supply port 1231 is connected to the indoor room through the first air outlet 114, and the vortex ring generating portion 126 is used to periodically drive the airflow to be blown out through the flow collecting member 123, or to periodically allow the airflow to pass through and be blown out through the flow collecting member 123. The flow collecting member 123 is rotatable relative to the housing 110 and has a rotation trajectory, and the centerline of the rotation trajectory does not coincide with the centerline of the air supply port 1231. In this way, by driving the flow collecting member 123 to rotate about its rotation trajectory, the air supply direction of the air supply port 1231 can be changed, thereby changing the air supply direction of the air conditioner indoor unit 100, making the indoor temperature distribution more uniform and improving the user experience.

[0056] See also Figure 4 and Figure 5In one embodiment, the air duct 122 is mounted on the housing 110, and the current collecting member 123 is rotatably connected to the air duct 122. In this embodiment, the air duct 122 is fixed to the housing 110, and the current collecting member 123 is rotatable relative to the air duct 122. It is understood that in another embodiment, the air duct 122 can rotate together with the current collecting member 123. Specifically, the air duct 122 is rotatably mounted on the housing 110, and the current collecting member 123 is connected to the air duct 122.

[0057] In order to better drive the current collecting member 123 to rotate, the air conditioner indoor unit 100 further includes a first driving device 130 . The first driving device 130 is connected to the current collecting member 123 to drive the current collecting member 123 to rotate.

[0058] There are many possible structures of the first driving device 130, which are not specifically limited here. Figure 5 、 Figure 6 and Figure 7 In one embodiment, the first driving device 130 includes a first motor 131 and a gear 132 disposed on the motor shaft of the first motor 131. The current collecting member 123 is provided with a rack 133 that meshes with the gear 132. The rack 133 extends along the circumference of the current collecting member 123. In another embodiment, the first driving device 130 includes a second motor and a first gear 132 disposed on the motor shaft of the second motor. The current collecting member 123 is provided with a second gear 132 that meshes with the first gear 132.

[0059] In addition, there is no specific limitation on the structure of the current collecting member 123. Figure 6 In one embodiment, the current collecting member 123 includes an air outlet ring 124, the air outlet 1231 is formed on the air outlet ring 124, and the rack 133 is provided on one end of the air outlet ring 124 close to the air cylinder 122. Figure 5 In another embodiment, the flow collecting member 123 further includes a guide tube 125 connected to the air outlet ring 124 , the air outlet 1231 is formed on the air outlet ring 124 , and the rack 133 is provided on the guide tube 125 .

[0060] Further, see Figure 5 and Figure 7 The vortex ring generating device 120 also includes a mounting bracket 127 installed on the second air outlet 122b, the mounting bracket 127 has a mounting ring 128, the current collecting member 123 is rotatably installed in the mounting ring 128, and the first driving device 130 is installed on the mounting bracket 127.

[0061] Specifically, the mounting ring 128 is located between the air duct 122 and the current collecting member 123 to connect the air duct 122 and the current collecting member 123. Considering that the current collecting member 123 is rotatably mounted in the mounting ring 128, in order to reduce the friction between the current collecting member 123 and the mounting ring 128, a plurality of first limiting ribs 1281 can be provided in the mounting ring 128. The plurality of first limiting ribs 1281 are arranged at intervals along the circumference of the mounting ring 128. Since the current collecting member 123 is rotatably engaged with the plurality of first limiting ribs 1281, the contact area between the current collecting member 123 and the mounting ring 128 can be reduced, thereby reducing the friction between the current collecting member 123 and the mounting ring 128, making it easier for the current collecting member 123 to rotate.

[0062] See also Figure 7 To prevent the current collecting member 123 from moving in the air supply direction driven by the airflow, a limiting portion 1282 can be provided at one end of the mounting ring 128 near the current collecting member 123. The limiting portion 1282 abuts against the current collecting member 123 to limit the position of the current collecting member 123 in the air supply direction. Specifically, the limiting portion 1282 can be an inward flange formed at the end of the mounting ring 128 near the current collecting member, but is not limited thereto.

[0063] In one embodiment, the limiting portion 1282 is arranged in a ring shape. In order to reduce the friction between the current collecting member 123 and the limiting portion 1282, a plurality of second limiting ribs 1283 are provided on the limiting portion 1282, and the plurality of second limiting ribs 1283 are arranged at intervals along the circumference of the limiting portion 1282. Since the current collecting member 123 abuts against the plurality of second limiting members, the contact area between the current collecting member 123 and the limiting portion 1282 can be reduced, thereby reducing the friction between the current collecting member 123 and the limiting portion 1282, and also making the current collecting member 123 easier to rotate. In this embodiment, the plurality of second limiting ribs 1283 are provided on the surface of the limiting portion 1282 close to the wind tube 122, and the plurality of first limiting ribs 1281 are provided on the inner edge of the limiting portion 1282.

[0064] On the basis of the above embodiments, in order to make the air flow blown out of the air outlet 1231 more uniform, the vortex ring generating device 120 further includes a rectifying component 140 (such as Figure 5 As shown), wherein the rectifying component 140 can be arranged on the side of the vortex ring generating portion 126 close to the wind tube 122; of course, the rectifying component 140 can also be arranged on the side of the vortex ring generating portion 126 away from the wind tube 122.

[0065] Specifically, the rectifying component 140 may be a rectifying plate, but is not limited thereto. The rectifying component 140 is used to rectify the airflow blowing toward the collecting member 123 , which is conducive to forming a stable vortex ring and realizing long-distance air supply, thereby making the indoor temperature distribution more uniform.

[0066] The present invention further provides an air conditioner comprising an outdoor unit and an indoor unit 100. The specific structure of the indoor unit 100 is similar to that of the aforementioned embodiments. Since the present air conditioner utilizes all of the technical solutions of all of the aforementioned embodiments, it at least possesses all of the beneficial effects brought about by the technical solutions of the aforementioned embodiments, which will not be described in detail here.
