Description

Technical Field

[0001] This invention relates to the field of household air cooler technology, and specifically to a household air cooler with a multi-dimensional air delivery structure. Background Technology

[0002] A household air cooler (also called an evaporative air cooler) is a household cooling device that combines fan ventilation with water evaporation for cooling. Its core principle is to use water evaporation to absorb heat and lower the air temperature. It also has the effects of air delivery and humidification, making it a low-cost and low-energy cooling tool.

[0003] Current household air coolers generally use a mechanical transmission mechanism to convert the rotational motion of the motor into the reciprocating oscillation of the blades, thereby achieving airflow direction adjustment. Since multiple sets of blades are connected to the same swing arm, all sets of blades swing in the same direction when working. When people sit on both sides of the air cooler and the middle is empty, the existing blade oscillation method cannot adapt to this, making it difficult to make full use of the output cold air.

[0004] Therefore, it is necessary to provide a household air cooler with a multi-dimensional air delivery structure to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a household air cooler with a multi-dimensional air supply structure to solve the problem mentioned in the background art that existing household air coolers generally use a mechanical transmission mechanism to convert the rotational motion of the motor into the reciprocating oscillation of the blades to achieve airflow adjustment. Since multiple sets of blades are connected to the same swing arm, all sets of blades oscillate in the same direction when working, making it difficult to make full use of the delivered cool air.

[0006] Based on the above ideas, the present invention provides the following technical solution: a household air cooler with a multi-dimensional air supply structure, including a housing and multiple sets of horizontal swing blades installed at the opening of the housing. The horizontal swing blades can swing back and forth in the horizontal plane around the axis of the pin installed on them. The end of the horizontal swing blade is provided with a swing rod. The positioning shaft installed at the end of the horizontal swing blade is inserted into the positioning hole on the swing rod, so that the swing rod, the positioning shaft and the pin form a swinging parallelogram structure. The pin and the positioning shaft are fixed together by a connector so that the positioning shaft and the pin move synchronously in the vertical direction.

[0007] The swing arm is provided in two sets and is respectively matched with the positioning shaft at both ends of the transverse swing blade. The two sets of swing arms swing back and forth in different directions.

[0008] An adjusting belt is provided around the periphery of the transverse oscillating blades. The adjusting belt is configured to divide the multiple sets of transverse oscillating blades into two parts and distribute them to the two sets of oscillating rods, so that the two sets of oscillating rods can deliver air to different directions outside the housing during the reciprocating swing.

[0009] As a further aspect of the present invention: a panel is fixed at the opening of the housing, and a square frame is fixed at the inner side of the panel, and the pin passes through the square frame and can move vertically relative to the square frame.

[0010] As a further aspect of the present invention: the pin on the transverse swing blade passes through the square frame and contacts the adjusting belt; the pin at the top of the transverse swing blade contacts the inner part of the adjusting belt; and the pin at the bottom of the transverse swing blade contacts the outer part of the adjusting belt, so that the part of the adjusting belt that contacts the pin can move in the same direction.

[0011] As a further aspect of the present invention: the adjusting belt has a first groove that penetrates the inner and outer portions of the adjusting belt; the pin at the bottom of the transverse blade extends to the first groove and engages with the outer portion of the adjusting belt; the adjusting belt has a second groove that engages with the pin at the top of the transverse blade; the second groove penetrates the inner portion of the adjusting belt; initially, the pins at the top of multiple transverse blades abut against the inner portion of the adjusting belt and are offset from the second groove, so that the positioning shafts at the top of multiple transverse blades are disengaged from the swing rod.

[0012] As a further aspect of the present invention: a first inclined surface is provided at the end of the first slot, and the pressure of the first inclined surface on the pin shaft can cause the pin shaft to move in the direction closer to the transverse swing blade.

[0013] As a further aspect of the present invention: the end of the second slot is provided with a second inclined surface. When the adjusting belt is reset, the second inclined surface presses against the top pin of the transverse swing blade, causing the pin to re-abut against the inner part of the adjusting belt.

[0014] As a further embodiment of the present invention: both ends of the transverse swing blade protrude outward to form protrusions, and the pin and the positioning shaft are both installed at the protrusions.

[0015] As a further aspect of the present invention: a round hole for inserting a pin and a positioning shaft is provided at the protrusion on the transverse swing blade, and an elastic element is fixed between the connector and the transverse swing blade to make the pin and the transverse swing blade elastically connected.

[0016] As a further aspect of the present invention: the swing arm is connected to the eccentric drive assembly, the eccentric drive assembly consists of an eccentric wheel and a cam shaft mounted on the eccentric wheel, the cam shaft and the axis of the eccentric wheel are offset from each other, and the swing arm is provided with a through groove for the cam shaft to pass through.

[0017] As a further aspect of the present invention: a longitudinal oscillating blade is installed at the opening of the housing, and the longitudinal oscillating blade is located outside the transverse oscillating blade.

[0018] Compared with the prior art, the beneficial effect of the present invention is that by disengaging a portion of the transverse pendulum from its engagement with the lower pendulum rod and establishing a connection with the upper pendulum rod, the transverse pendulum, divided into two parts, can rotate in different directions during the reciprocating swing of the two sets of pendulum rods. See details [link to specific description]. Figure 12 As shown, by controlling the distance the belt moves, the division of areas m and n can be controlled, which is beneficial to adjust the area of ​​the air outlet according to the number of people in the seats, thereby maximizing the utilization of the exhaust airflow.

Detailed Implementation

[0033] like Figures 1-12 As shown, a household air cooler with a multi-dimensional airflow structure includes a housing 1 and multiple sets of longitudinal blades 2 and multiple sets of transverse blades 3 disposed at the opening of the housing 1. The longitudinal blades 2 are used to adjust the airflow direction in the vertical direction, while the transverse blades 3 adjust the airflow direction in the horizontal direction. The housing 1 houses components such as a water tank, a water pump, a fan, a wet curtain, and a water distributor. The water pump draws cold water from the water tank to the water distributor and then delivers it to the wet curtain. The fan provides the airflow power. When the air passes through the wet curtain, the temperature of the outlet air decreases due to the heat absorption of water evaporation. Specifically, the air cooler can be selected from existing technologies, which will not be elaborated here.

[0034] Combination Figures 1-3 As shown, a U-shaped panel 5 is fixed to the opening of the housing 1, and a square frame 6 is fixed to the inner side of the panel 5. (Refer to...) Figure 4 As shown, the horizontal swing blade 3 is connected to the square frame 6 via a pin 301, allowing the horizontal swing blade 3 to swing horizontally. Specifically, the pin 301 passes through the square frame 6 and can move vertically relative to the square frame 6. Furthermore, swing rods 12 are provided at both the upper and lower ends of the horizontal swing blade 3, and the horizontal swing blade 3 is connected to the swing rods 12 via a positioning shaft 302, so that the swing rods 12, the positioning shaft 302, and the pin 301 form a parallelogram swing structure. The swing rods 12 are driven by an eccentric drive assembly to reciprocate, so that during the movement of the swing rods 12, multiple sets of horizontal swing blades 3 can be rotated.

[0035] The eccentric drive assembly is similar to the drive mechanism in existing air coolers, both consisting of an eccentric wheel 13 and a cam shaft 1301 mounted on the eccentric wheel 13. (Refer to...) Figure 3As shown, the convex shaft 1301 can be selectively fixed or rotatably connected to the eccentric wheel 13, and the axes of the convex shaft 1301 and the eccentric wheel 13 are offset from each other. The swing rod 12 has a T-shaped structure, and its protruding part has a through groove 1202 that slides with the convex shaft 1301. During the rotation of the convex shaft 1301 driven by the eccentric wheel 13, the convex shaft 1301 can slide in the through groove 1202, and the pressure of the convex shaft 1301 on the side wall of the through groove 1202 can drive the swing rod 12 to reciprocate in the horizontal plane to adjust the air outlet angle of the transverse swing blade 3. Unlike existing technologies, the swing rods 12 located at both ends of the transverse swing blades 3 always swing in opposite directions. Furthermore, among the multiple sets of transverse swing blades 3, a portion of the continuous transverse swing blades 3 can be selectively coupled to one of the swing rods 12, while another portion of the continuous transverse swing blades 3 is coupled to another swing rod 12. This structure allows the multiple sets of transverse swing blades 3 to be divided, directing the airflow towards different areas. See [reference needed] for details. Figure 12 As shown, one part of the horizontal oscillating blades 3 faces to one side and delivers air to area m, while the other part of the horizontal oscillating blades 3 faces to the other side and delivers air to area n. Compared with the uniform swing of the horizontal oscillating blades 3 in traditional air coolers, the horizontal oscillating blades 3 in this scheme can simultaneously deliver airflow in different directions, which is beneficial to maximizing the utilization of the delivered airflow.

[0036] In practical use, in order to adjust the range of regions m and n, this scheme provides an adjusting belt 8 on the outside of the transverse swing blade 3. The adjusting belt 8 can be, for example, a flexible belt with a certain thickness, and the adjusting belt 8 is a closed ring structure. Figure 3 , Figures 5-7 The diagram illustrates the arrangement of the adjusting belt 8, which is a U-shaped structure covering multiple sets of transverse blades 3. Pins 301 on the transverse blades 3 pass through the square frame 6 and contact the adjusting belt 8. It should be noted that the pin 301 at the top of the transverse blades 3 contacts the inner part of the adjusting belt 8. Figure 6 Part a; while the pin 301 located at the bottom end of the transverse sway vane 3 contacts the outer part of the adjusting belt 8, that is: Figure 6 part b in, combined with Figures 6-7 As shown, this method enables the portion of the adjusting belt 8 that contacts the pin 301 to move in the same direction.

[0037] Furthermore, the adjusting belt 8 has a first slot 801 that penetrates both the inner and outer portions of the adjusting belt 8, allowing the pin 301 at the bottom of the transverse oscillating blade 3 to pass through the first slot 801 on the inner side of the adjusting belt 8 and extend to the first slot 801 on the outer side. The adjusting belt 8 also has a second slot 802 that engages with the pin 301 at the top of the transverse oscillating blade 3, penetrating the inner portion of the adjusting belt 8. Initially, the pins 301 at the top of the multiple sets of transverse oscillating blades 3 are all abutted against the inner portion of the adjusting belt 8 and offset from the second slot 802, disengaging the positioning shaft 302 at the top of the transverse oscillating blade 3 from the swing rod 12. Meanwhile, the pins 301 at the bottom of the multiple sets of transverse oscillating blades 3 are all located at the first slot 801, allowing the positioning shaft 302 at the bottom of the transverse oscillating blade 3 to engage with the swing rod 12.

[0038] Combination Figures 1-5 As shown, the pin 301 and the positioning shaft 302 are fixedly connected by a plate-shaped connector 15, so that the pin 301 and the positioning shaft 302 can move synchronously in the vertical direction. The rocker arm 12 is provided with a positioning hole 1201 that cooperates with the positioning shaft 302. When the adjusting belt 8 squeezes the pin 301 and causes the pin 301 to move towards the transverse rocker arm 3, one end of the positioning shaft 302 can be moved out of the positioning hole 1201 on the rocker arm 12, so that the rocker arm 12 is disengaged from the transverse rocker arm 3.

[0039] As described above, since the pins 301 at the top of the multiple sets of horizontal blades 3 initially abut against the inner part of the adjusting belt 8, the multiple sets of horizontal blades 3 are disengaged from the upper swing rod 12. Under these circumstances, by driving the lower swing rod 12 to reciprocate in the horizontal plane, the air outlet angle of the multiple sets of horizontal blades 3 can be uniformly adjusted. This part is similar to the structure of existing air coolers.

[0040] When it is necessary to divide multiple sets of transverse oscillating blades 3 into zones, the adjusting belt 8 can be driven along... Figure 7The movement is directed in the direction indicated by the middle arrow, aligning the pin 301 at the top of the transverse swing blade 3 with the second slot 802. This causes the pin 301 at the top of the transverse swing blade 3 to spring outwards, while the positioning shaft 302 springs out and inserts into the positioning hole 1201 of the upper swing rod 12. Simultaneously, the pin 301 below the transverse swing blade 3 is offset from the first slot 801 and abuts against the outer part of the adjusting belt 8. By adjusting the pressure of the belt 8 on the pin 301 below the transverse swing blade 3, the pin 301 moves closer to the transverse swing blade 3, causing the positioning shaft 302 to disengage from the lower swing rod 12. Thus, a portion of the transverse swing blade 3 disengages from the lower swing rod 12 and establishes a connection with the upper swing rod 12. This allows the two transverse swing blades 3, divided into two parts, to rotate in different directions during the reciprocating swing of the two sets of swing rods 12. (See attached diagram). Figure 12 As shown, by controlling the distance the belt 8 moves, the divided areas m and n can be controlled, which is beneficial to adjust the area of ​​the air outlet according to the number of people in the seats, thereby maximizing the utilization of the outgoing airflow.

[0041] Reference Figures 1-3 As shown, a first motor 14 is fixed at both the top and bottom of the transverse oscillating blade 3 inside the housing 1. The output shaft of the first motor 14 is connected to the eccentric wheel 13 to drive the eccentric wheel 13 to rotate. Figures 3-5 As shown, rotating shafts 7 are provided at the beginning, end, and bends of the adjusting belt 8. It should be noted that the rotating shafts 7 and the adjusting belt 8 can be connected by friction or by meshing. A second motor 16 is installed at one of the rotating shafts 7. The second motor 16 is fixedly installed inside the housing 1, and its output end is connected to the rotating shaft 7 to drive it to rotate, thereby rotating the adjusting belt 8 to distribute the multiple sets of transverse blades 3. The cross-section of the rotating shaft 7 along its own axis can be T-shaped to prevent the rotating shaft 7 from disengaging from the adjusting belt 8.

[0042] In actual use, support components are provided at both ends of the swing arm 12. The support components and the swing arm 12 form a parallelogram swing structure to maintain the stability of the swing arm 12. Specifically, the support components include a support member 10, a rotating rod 9, and a connecting rod 11. The connecting rod 11 is selectively fixed to the housing 1 or the panel 5, and the connecting rod 11 is coaxially arranged with the pin 301. The rotating rod 9 is rotatably connected to the connecting rod 11 along the circumferential direction. One end of the shaft-shaped support member 10 is inserted into the positioning hole 1201 at the end of the swing arm 12, and the other end is rotatably engaged with the rotating rod 9 through a tapered roller bearing. This structure is beneficial for supporting the swing arm 12, thereby maintaining the stability of the swing arm 12.

[0043] Reference Figures 1-2 As shown, the longitudinal swing blade 2 can be adjusted by manual drive, or it can be driven to swing by a mechanism similar to that at the transverse swing blade 3. Specifically, the longitudinal swing blade 2 can be selected from the existing technology, which will not be elaborated here.

[0044] Reference Figure 3 As shown, a retainer 4 is fixedly installed on the inner side of the square frame 6, and the transverse swing blade 3 is hinged to the retainer 4. Specifically, the hinge axis is collinear with the axis of the pin 301. This structure helps to improve the stability of the transverse swing blade 3 during installation.

[0045] Reference Figure 5 As shown, a first stop 501 and a second stop 502 with plate-like structures are fixed on the inner wall of the panel 5. Specifically, the first stop 501 is located at the top of the transverse swing blade 3 and contacts the inner side of the adjusting belt 8 away from the pin 301. The second stop 502 is located at the bottom of the transverse swing blade 3 and contacts the outer side of the adjusting belt 8 away from the pin 301. This structure helps to support the adjusting belt 8, so that the adjusting belt 8 can be stably engaged with the pin 301.

[0046] Reference Figure 8 As shown, the end of the first slot 801 is provided with a first inclined surface 8011. When the adjusting belt 8 is in accordance with... Figure 7 When moving in the direction indicated by the middle arrow, the pressure exerted on the pin 301 by the first inclined surface 8011 causes the first pin 301 to move towards the transverse swing blade 3. (Refer to...) Figure 10 As shown, the end of the second slot 802 is provided with a second inclined surface 8021. When the adjusting belt 8 is reset, the second inclined surface 8021 presses against the top pin 301 of the transverse swing blade 3, which can cause the pin 301 to abut against the inner part of the adjusting belt 8 again.

[0047] Reference Figure 11 As shown, both ends of the transverse swing blade 3 protrude outward to form protrusions 303, and the pin 301 and the positioning shaft 302 are installed at the protrusions 303. In actual use, the protrusions 303 on the transverse swing blade 3 are provided with round holes for the pin 301 and the positioning shaft 302 to be inserted. An elastic element 17 is fixed between the connecting member 15 and the transverse swing blade 3. The elastic element 17 can be, for example, a spring, so as to realize the elastic engagement between the pin 301 and the transverse swing blade 3. When the pin 301 is disengaged from the adjusting belt 8, the elastic force of the elastic element 17 allows the pin 301 and the positioning shaft 302 to pop outward.

[0048] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.
