Description

Technical Field

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

[0002] The existing air conditioner indoor unit blows the air flow after heat exchange through a conventional air outlet of the air conditioner. Its air outlet mode is conventional air outlet, and the air flow coming out of the conventional air outlet is fixed. Its radiation range is short and narrow, and it is impossible to achieve large-range and long-distance air supply. Thus, the room temperature distribution is not uniform. For example, during refrigeration, the temperature is cold near the air outlet of the air conditioner, while the temperature is relatively high far from the air outlet of the air conditioner. If the temperature in the distance is to reach the set temperature, the overall room temperature needs to be lowered to meet the requirement, or the air outlet direction is adjusted through a moving mechanism such as a deflector or louvers. Although the traditional air outlet auxiliary moving structures such as deflectors and louvers can change the overall air flow direction at the air outlet of the air conditioner to a certain extent, they are still far from achieving the functions of directional and fixed-point air supply.

[0003] Installing a vortex ring generating device on the air conditioner can achieve long-distance air supply. However, the independent setting of a fan in the vortex ring generating device will cause the structure of the air conditioner indoor unit to be complex, occupy a large space, and have high production and manufacturing costs.

[0009] The vortex ring air supply part is installed at the main air outlet. The vortex ring air supply part has a secondary air outlet and an air supply port.

[0013] In one embodiment, the air conditioner indoor unit further includes a heat exchanger, and the heat exchanger is installed in the heat exchange air duct and is inclined.

[0014] In one embodiment, the fan assembly is arranged below the heat exchanger and at the lower end of the heat exchange air duct.

[0015] In one embodiment, the fan assembly is an axial flow fan, a centrifugal fan, a cross-flow impeller or a mixed flow fan.

[0016] In one embodiment, the air supply port is circular.

[0017] In one embodiment, the vortex ring generating part includes a driving device and a switch door. The switch door is installed in the heat exchange air duct to block the airflow from the main air inlet to the air supply port. The driving device is connected to the switch door to drive the switch door to open or close.

[0018] In one embodiment, the flow collector is a flow collecting cover, and the flow collecting cover is tapered from the secondary air outlet to the air supply port.

[0019] The present invention also provides an air conditioner, which includes an air conditioner indoor unit and an air conditioner outdoor unit connected by a refrigerant pipe. Among them, the air conditioner indoor unit includes a housing, a fan assembly, a vortex ring air supply part and a vortex ring generating part.

[0020] The housing has a main air inlet, a main air outlet and a heat exchange air duct connecting the main air inlet and the main air outlet.

[0021] The fan assembly is installed in the heat exchange air duct, and the fan assembly drives the airflow to flow from the main air inlet to the main air outlet.

[0022] The vortex ring air supply part is installed at the main air outlet. The vortex ring air supply part has a secondary air outlet and an air supply port.

[0036] The realization of the object, functional features and advantages of the present invention will be further described in conjunction with the embodiments and with reference to the accompanying drawings. Specific embodiments

[0037] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0038] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution where A and B are satisfied simultaneously.

[0039] The present invention provides an indoor unit of an air conditioner, which can be a floor-standing indoor unit of an air conditioner, a mobile air conditioner, a wall-mounted indoor unit of an air conditioner, a window air conditioner, etc.

[0040] In the embodiments of the present invention, as Figures 1 to 8 shown, the indoor unit of the air conditioner includes a housing 1, a fan assembly 2, a vortex ring air supply part 3 and a vortex ring generating part 4.

[0041] The housing 1 has a main air inlet 11, a main air outlet 12 and a heat exchange air duct 13 connecting the main air inlet 11 and the main air outlet 12;

[0042] The fan assembly 2 is installed in the heat exchange air duct 13, and the fan assembly 2 drives the air flow to flow from the main air inlet 11 to the main air outlet 12;

[0043] The vortex ring air supply part 3 is installed at the main air outlet 12. The vortex ring air supply part 3 has a secondary air outlet 312 and an air supply outlet 321. The air passing area of the air supply outlet 321 is smaller than the air passing area of the secondary air outlet 312. The secondary air outlet 312 is communicated with the heat exchange air duct 13, and the air supply outlet 321 is arranged corresponding to the main air outlet 12; and

[0044] The vortex ring generating part 4 is installed on the heat exchange air duct 13 to open or block the heat exchange air duct 13, and the vortex ring generating part 4 has a periodic opening state and a normally open state.

[0045] In this embodiment, the housing 1 can be of an integral structure or can be formed by splicing several plates. The shapes of the main air inlet 11, the main air outlet 12, the secondary air outlet 312, and the air supply port 321 can be circular, elliptical, rectangular, polygonal, irregular, etc., or can be multiple micro holes, and their sizes and shapes are not specifically limited herein. The heat exchange air duct 13 means that the air flow entering from the main air inlet 11 can exchange heat in this channel and then be blown out from the main air outlet 12. The cross-sectional shape of the heat exchange air duct 13 can be circular, elliptical, arc-shaped, etc., and its extending shape can be straight cylindrical or bent, etc. The heat exchange air duct 13 can be directly formed by enclosing the housing 1 or can be formed by enclosing the inner wall of the air duct in the housing 1. The vortex ring air supply part 3 can be installed on the outer wall surface of the housing 1, can be installed inside the housing 1, or can be embedded on the housing 1. The vortex ring air supply part 3 and the housing 1 can be integrally formed or can be separately formed.

[0046] Figure 8 A two-dimensional simulation diagram of the formation of a vortex ring at the air supply port 321 of the vortex ring air supply part 2 is given. Here, the simulation is only a two-dimensional simulation of a radius cross-section of one air supply port 321. In other words, the two-dimensional simulation of the radius cross-section obtains a single vortex, the two-dimensional simulation of the diameter cross-section obtains a pair of vortices, and the three-dimensional simulation obtains a vortex ring. By making the air passing area of the air supply port 321 smaller than the air passing area of the secondary air outlet 312, therefore, in the air flow flowing from the secondary air outlet 312 to the air supply port 321, part of the air flow will flow along the inner wall surface of the vortex ring air supply part 3 and then flow out from the periphery of the air supply port 321, and the other part of the air flow will flow out from the middle of the air supply port 321. The part of the air flow flowing out from the edge of the air supply port 321 is defined as the edge air flow, and the air flow flowing out from the middle of the air supply port 321 is positioned as the middle air flow. Then, the edge air flow is subject to the resistance of the inner wall surface of the vortex ring air supply part 3. Compared with the middle air flow, the flow velocity is lower. This difference in flow velocity will cause a vortex ring air flow when the air flow flows out from the air supply port 321.

[0047] The vortex ring generating part 4 is installed in the heat exchange air duct 13, that is, the vortex ring generating part 4 can be installed inside the housing 1 or in the vortex ring air supply part 3. The vortex ring generating part 4 can be installed in the heat exchange air duct 13 in a detachable manner, or can be integrally formed with the housing 1 or the vortex ring air supply part 3. The vortex ring generating part 4 can be a structure such as a switch door 42, a fan structure, etc., as long as it can block and open the heat exchange air duct 13, and has a periodically open state and a normally open state. By setting the air outlet 321 corresponding to the main air outlet 12, the air conditioner indoor unit uses one air outlet both when the vortex ring generating part 4 is in the periodically open state and the normally open state. Then, in the conventional air supply mode and the vortex ring air supply mode in the air conditioner indoor unit, a common air outlet 321 is used, and the air sent out is the air flow after heat exchange. In this way, the structure of the air conditioner indoor unit is simplified, different user needs can be met, the user experience is improved, and the trend of consumption upgrading is satisfied.

[0048] It should be noted that when the vortex ring generating part 4 is closed, that is, blocking the air flow in the heat exchange air duct 13 from flowing to the air outlet 321, the vortex ring generating part 4 can completely block the heat exchange air duct 13, or can partially close the heat exchange air duct 13. For example, only 2 / 3, 4 / 5, 5 / 6, 9 / 10, etc. of the channel cross-section of the heat exchange air duct 13 is closed. It can be understood that when the vortex ring generating part 4 is in the periodically open state, that is, when the vortex ring generating part 4 works, at this time the air conditioner indoor unit is in the vortex ring air supply mode. When the heat exchange air duct 13 is blocked, since the fan assembly 2 is continuously drawing in air, a certain volume of air will accumulate in the heat exchange air duct 13. When the heat exchange air duct 13 is opened, due to the pressure difference, a driving force is formed to drive the air flow to flow to the air outlet 321, and the air passing area of the air outlet 321 of the vortex ring air supply part 3 is smaller than the air passing area of the secondary air outlet 312, then the vortex ring air flow can be blown out from the air outlet 321. The vortex ring generating part 4 being in the periodically open state can stably output the vortex ring air flow from the air outlet 321. At the same air volume, the vortex ring air supply method can achieve directional, fixed-point, and long-distance air supply. And during the transmission of the vortex ring, heat exchange occurs with the surrounding ambient air, and the temperature difference between the vortex ring temperature and the surrounding air temperature is not large, ensuring that there will be no obvious overcooling or overheating feeling when the vortex ring blows on people, improving comfort. When the vortex ring generating part 4 is in the normally open state, at this time the air conditioner indoor unit is in the conventional air supply mode, that is, when the vortex ring generating part 4 is in the power-off state, that is, when the vortex ring generating part 4 does not work, the vortex ring generating part 4 is in the normally open state, so that the air flow at the main air inlet 11 can continuously and smoothly blow out from the air outlet 321.

[0049] Specifically, please refer to Figures 2 to 7, the blower assembly 2 can be an axial flow fan, a centrifugal fan, a cross-flow impeller, a mixed-flow fan, etc. As long as it can drive sufficient air flow to blow from the main air inlet 11 to the main air outlet 12. And for the vortex ring air supply mode and the conventional air supply mode of the air conditioner indoor unit, two blower assemblies 2 do not have to be used. The entire air conditioner indoor unit can use one blower assembly 2 to drive sufficient air flow, thus simplifying the overall structure of the unit and reducing the cost. When the blower assembly 2 is an axial flow fan, it can be a single axial flow fan, or a contra-rotating fan or a multi-stage fan. In this way, the power of the blower assembly 2 can be increased and the air volume can be greatly improved. The blower assembly 2 can be installed below the heat exchanger 5 in the heat exchange air duct 13, or above the heat exchanger 5. When the blower assembly 2 is of different types, the opening positions of the main air outlet 12 and the main air inlet 11 can be adjusted accordingly, and it should be ensured that the entire air conditioner indoor unit shares one air outlet and has a vortex ring air supply mode and a conventional air supply mode.

[0050] In the air conditioner indoor unit of the present invention, by installing the vortex ring air supply part 3 at the main air outlet 12, the air supply port 321 is arranged corresponding to the main air outlet 12, so that the air passing area of the air supply port 321 is smaller than that of the secondary air outlet 312. The vortex ring generating part 4 is used to open or block the heat exchange air duct 13, and has a periodic opening state and a normally open state. Then, when the vortex ring generating part 4 is in the periodic opening state, a vortex ring air flow is blown out from the air supply port 321 to achieve directional, fixed-point and long-distance air supply. When the vortex ring generating part 4 is in the normally open state, the air supply port 321 blows out the conventional air after heat exchange, so that the air conditioner indoor unit has multiple air supply modes. At the same time, by installing the blower assembly 2 in the heat exchange air duct 13 and making the blower assembly 2 drive the air flow to flow from the main air inlet 11 to the main air outlet 12, the air conditioner indoor unit uses one blower assembly 2 to drive in the vortex ring air supply mode and the conventional air supply mode, thus simplifying the structure of the air conditioner indoor unit, reducing the occupied space of the machine, and having low production and manufacturing costs.

[0051] Specifically, as Figure 2 and Figure 3 shown, the vortex ring air supply part 3 includes a wind cylinder 31 and a flow collector 32. The wind cylinder 31 is provided with a secondary air inlet 311 and a secondary air outlet 312. The secondary air inlet 311 is communicated with the heat exchange air duct 13. The flow collector 32 is installed at the secondary air outlet 312, and the flow collector 32 is provided with an air supply port 321.

[0052] In this embodiment, the vortex ring air supply part 3 includes an air duct 31 and a flow collector 32, which can increase the air supply space of the vortex ring air supply part 3 and is more conducive to the formation of a vortex ring. The flow collector 32 and the air duct 31 can be integrally formed or separately formed. It can be understood that when the flow collector 32 and the air duct 31 are separately formed, the flow collector 32 and the air duct 31 are hermetically connected. When the flow collector 32 and the air duct 31 are integrally formed, a virtual dividing line is defined with the connection between the air duct 31 and the flow collector 32 as the boundary. One side of the dividing line is the air duct 31, and the other side is the flow collector 32, and a secondary air outlet 312 of the air duct 31 is formed at the dividing line. Undoubtedly, the air passing area of the secondary air outlet 312 is larger than the air passing area of the air supply port 321 of the flow collector 32. The extending directions of the outer wall surfaces of the flow collector 32 and the air duct 31 can be the same, that is, the length extension lines of their outer wall surfaces are in a straight line. At this time, the vortex ring air supply part 3 has a complete shape without a wiring connection. The extending directions of the outer wall surfaces of the flow collector 32 and the air duct 31 can be different, that is, the length extension lines of their outer wall surfaces are arranged at an angle. At this time, a wiring connection will be formed at the connection between the flow collector 32 and the air duct 31.

[0053] In one embodiment, an inner wall of an air duct is provided inside the housing 1, and the inner wall of the air duct encloses to form a heat exchange air duct 13. The inner wall of the air duct is connected to the flow collector 32. By forming the heat exchange air duct 13 through the inner wall of the air duct, compared with directly forming the air duct by the inner cavity of the housing 1, it is easier to ensure the sealing performance and stability of the heat exchange air duct 13. The flow collector 32 and the inner wall of the air duct can be integrally formed or separately formed. The flow collector 32 and the inner wall of the air duct can be detachably connected by means of screws, snap connections, etc.

[0054] In a preferred embodiment, as Figures 1 to 7 shown, the housing 1 extends vertically. The main air inlet 11 is opened at the lower end of the housing 1, and the main air outlet 12 is opened at the upper end of the housing 1. The fan assembly 2 is arranged close to the main air inlet 11. In this way, air flows from the air inlet at the lower end of the housing 1 to the main air outlet 12 at the upper end of the housing 1, that is, to the air supply port 321. When the air conditioner indoor unit is in the vortex ring air supply mode, the vortex ring air flow blown out from the air supply port 321 at the upper end of the housing 1 has a certain distance from the ground, has sufficient air supply space, and is not easily blocked by the ground, so the air supply can be sent farther, and it is easier to achieve directional, fixed-point, and long-distance air supply. When the air conditioner indoor unit is in the conventional air supply mode, the air supply radiation range from the air supply port 321 at the upper end of the housing 1 is large and more in line with the user's air blowing requirements. Arranging the fan assembly 2 close to the main air inlet 11 ensures sufficient air intake, so as to drive sufficient air flow into the housing 1.

[0055] In one embodiment, please refer to Figures 2 to 7, the indoor air conditioner further includes a heat exchanger 5, which is installed in the heat exchange air duct 13 and is inclined. The heat exchanger 5 can be a finned-tube evaporator, a plate evaporator, etc. By arranging the heat exchanger 5 inclined in the heat exchange air duct 13, sufficient air inlet space can be formed while ensuring that the heat exchanger 5 can exchange heat. It can be understood that the windward surface of the heat exchanger 5 faces the air inlet.

[0056] On the basis of the above embodiments, further, the fan assembly 2 is arranged below the heat exchanger 5 and is located at the lower end of the heat exchange air duct 13. Installing the fan assembly 2 below the heat exchanger 5 can make full use of the space between the heat exchanger 5 and the housing 1, thus making the overall structure more compact. And it can ensure that a sufficient amount of air flow passes through the heat exchanger 5 for heat exchange, so that the heat exchange effect of the indoor air conditioner is better.

[0057] In a preferred embodiment, as Figure 1 shown, the air outlet 321 is circular. When the air outlet 321 is square or polygonal, the stress is more concentrated at the corner transition of the air outlet 321, and the air resistance received by the periphery of the air outlet 321 is uneven, thus generating a relatively large noise. By making the air outlet 321 circular, the air resistance received is small and uniform, so the noise generated when the air outlet 321 supplies air is smaller.

[0058] In an embodiment, please refer to Figures 2 to 5 , the vortex ring generating part 4 includes a driving device 41 and a switch door 42. The switch door 42 is installed in the heat exchange air duct 13 to block the air flow from the main air inlet 11 to the air outlet 321. The driving device 41 is connected to the switch door 42 to drive the switch door 42 to open or close.

[0059] In this embodiment, the driving device 41 may include a control board and a driving member. The control board controls the driving member to drive the switch door 42 to periodically open or close the heat exchange air duct 13, and can also drive the switch door 42 to be in an always-open state. The driving device 41 may be disposed inside the heat exchange air duct 13 or outside the heat exchange air duct 13. In order to prevent the driving device 41 from obstructing the air flow inside the heat exchange air duct 13, preferably, the control member is disposed outside the heat exchange air duct 13. The switch door 42 is disposed inside the heat exchange air duct 13 and divides the heat exchange air duct 13 into two parts. Then, the switch door 42 can be used to block the air flow from the main air inlet 11 to the air supply port 321. When the switch door 42 is in the always-open state, the vortex ring generating part 4 does not work, and the air conditioner indoor unit is in the conventional air supply mode. At this time, the air flow inside the heat exchange air duct 13 directly flows out from the air supply port 321. When the switch door 42 is closed, that is, the air flow inside the heat exchange air duct 13 is blocked from flowing to the air supply port 321, and the main air inlet 11 continuously admits air. At this time, a certain amount of air flow can be accumulated inside the heat exchange air duct 13 to form a certain pressure. Thus, when the switch door 42 is opened, the air flow inside the heat exchange air duct 13 can form a driving force and blow out from the air supply port 321 to form a vortex ring. In this way, the periodic opening or closing of the switch door 42 enables the air flow to flow out in a pulsed manner, so that the air conditioner indoor unit has a vortex ring air supply mode and can realize long-distance and directional air supply of the vortex ring. The switch door 42 can be a louver structure, a fan structure, a door panel structure, etc., as long as it can periodically block the air flow inside the heat exchange air duct 13 from flowing to the flow collector 32 to form a vortex ring and blow out. Through the structure of the driving device 41 plus the switch door 42, the structure is simple, stable, and easy to control, thus being more conducive to the smooth generation of the vortex ring air flow.

[0060] In combination with the above embodiment having the flow collector 32, further, as Figures 1 to 3 shown, the flow collector 32 is a flow collecting cover, and the flow collecting cover is tapered from the secondary air outlet 312 to the air supply port 321. The cross-sectional shape of the flow collecting cover can be circular, elliptical, rectangular, etc. In order to reduce the wind resistance, the flow collecting cover is generally cylindrical. By making the flow collecting cover tapered from the secondary air outlet 312 to the air supply port 321, the flow collecting cover can collect the air sent out from the secondary air outlet 312 and make the generation and blowing of the vortex ring smoother.

[0061] In another embodiment, the current collector 32 is a current collecting plate which is installed at the air outlet. An air supply opening 321 is formed in the current collecting plate. The current collecting plate can be a plate covering the secondary air outlet 312. By forming an air supply opening 321 smaller than the secondary air outlet 312 in the current collecting plate, when the air flow blows from the secondary air outlet 312 to the air supply opening 321, due to the partial blocking effect of the current collecting plate, the air flow blown out from the air supply opening 321 can be in a vortex ring shape. Moreover, the structure of the current collecting plate is simple and easy to manufacture and process. In other embodiments, the current collector 32 can also be formed by enclosing several plates. By setting the air supply opening 321 on one of the plates, the formation of a vortex ring can also be achieved.

[0062] The present invention also provides an air conditioner, which includes an outdoor unit and an indoor unit of the air conditioner. The outdoor unit and the indoor unit of the air conditioner are connected by a refrigerant pipe. The specific structure of the indoor unit of the air conditioner refers to the above embodiments. Since this air conditioner adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0063] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
