Description

Technical Field

[0002] Traditional cabinet air-conditioning units are equipped with a heat exchanger to exchange heat for the fluid, and the motor drives the fan to rotate as the power to drive the air to flow in the air-conditioning unit. This form of air outlet requires the fan to be set on the outside of the air-conditioning unit shell and connected to the air outlet to attract the air flow from the air inlet to the air outlet. At this time, the static pressure of the air-conditioning unit only depends on the size of the internal cavity of the air-conditioning unit shell. If the shell volume is set to be smaller, the air flow will be directly discharged from the air inlet to the air outlet. Turbulence is likely to occur in the air in the shell, resulting in large noise and vibration of the shell, and the static pressure of the air outlet cannot be adjusted to meet the preset range. The user's comfort is poor. In order to control the static pressure within the preset range, the shell volume needs to be increased to control the outlet static pressure to reach the preset range, thereby reducing the noise and vibration of the shell, but this also increases the manufacturing cost.

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0053] The traditional cabinet air-conditioning unit is provided with a heat exchanger to exchange heat with the fluid, and the motor drives the fan to rotate as the power to drive the air to flow in the air-conditioning unit. For this air outlet form, the fan needs to be arranged on the outside of the air-conditioning unit shell 10 and connected with the air outlet 12 to attract the air flow from the air inlet 11 to the air outlet 12. At this time, the static pressure of the air-conditioning unit only depends on the size of the internal cavity of the air-conditioning unit shell 10. If the volume of the shell 10 is set to be smaller, the air flow will be directly discharged from the air inlet 11 to the air outlet 12. The air in the shell 10 is prone to turbulence, resulting in greater noise and vibration of the shell 10, and the static pressure of the air outlet 12 cannot be adjusted to meet the preset range. The user's comfort is poor. In order to control the static pressure within the preset range, it is necessary to increase the volume of the shell 10 to control the outlet static pressure of the air outlet 12 to reach the preset range, thereby reducing the noise and vibration of the shell 10, but this also increases the manufacturing cost.

[0054] In order to solve the technical problem in the prior art that the shell 10 is often large in size in order to stabilize the static pressure of the air-conditioning unit, the main purpose of the present application is to provide a static pressure regulating component and an air-conditioning unit that can effectively reduce the volume of the shell 10 on the basis of meeting the static pressure requirements of the user during use.

[0055] Therefore, the static pressure of the air-conditioning unit is a constant value, and the static pressure of the air-conditioning unit cannot be adjusted, resulting in the inability to adjust the static pressure of the air-conditioning unit to meet the different usage requirements of the user during the use of the air-conditioning unit, affecting the user's comfort. By arranging the guide mechanism 20 in the shell 10, the first guide component in the guide mechanism 20 is meshed and transmitted with the second guide component, and after the driving member 21 drives the first guide component to rotate, the second guide component rotates synchronously with the first guide component, and the fluid is guided from the shielding area 26 to the regulating chamber 13 on both sides, and finally the fluid converges at the front end of the air outlet 12 and is discharged through the air outlet 12, thereby achieving the purpose of flexibly adjusting the static pressure in the shell 10 through the guide mechanism 20 to meet different usage requirements.

[0056] refer to Figure 1-Figure 4 As shown, according to one aspect of the present application, a static pressure regulating assembly is provided, including a shell 10 and a flow guide mechanism 20, the shell 10 includes an air inlet 11, an air outlet 12 and a regulating chamber 13, the fluid is discharged from the air inlet 11 to the air outlet 12 through the regulating chamber 13, the flow guide mechanism 20 includes a driving member 21 and a plurality of flow guide members 22, an engaging structure 25 is provided between adjacent flow guide members 22, a plurality of flow guide members 22 are arranged in the regulating chamber 13, the driving member 21 drives one of the flow guide members 22 to rotate so that the fluid is discharged to the regulating chamber 13 outside the flow guide member 22.

[0057] A flow guide mechanism 20 is provided in the regulating chamber 13 of the shell 10. A plurality of flow guide members 22 in the flow guide mechanism 20 are meshed for transmission. After the driving member 21 drives one flow guide member 22 to rotate, the other plurality of flow guide members 22 can follow. Through the flow guide members 22, the fluid is discharged from the air inlet 11 to the air outlet 12 along the outer peripheral side along the rotation direction of the flow guide members 22. Therefore, on the one hand, the flow guide mechanism 20 is used as the power to drive the fluid flow. On the other hand, since a plurality of the flow guide members 22 are provided in the regulating chamber 13, a driving member 21 drives a plurality of flow guide members 22 to rotate through meshing transmission. While increasing the power, a plurality of the flow guide members 22 change the flow direction of the fluid in the regulating chamber 13, guide the flow of the fluid, and effectively avoid the problem of turbulence of the fluid in the regulating chamber 13. Therefore, the noise and vibration of the shell 10 are reduced. On the basis of effectively reducing the size of the shell 10, the static pressure at the air outlet 12 is kept at a very constant size, thereby improving the comfort of the user during use.

[0058] In one embodiment, after the driving member 21 drives one of the guide members 22 to rotate, at least one of the guide members 22 discharges the fluid to both sides of the shell 10 to increase the moving path of the fluid in the regulating chamber 13 and prevent the fluid from flowing directly in a straight line along the air inlet 11 to the air outlet 12.

[0059] At the same time, when the driving member 21 drives the guide member 22 to rotate, the guide member 22 drives the fluid to flow along the arc-shaped airflow channel formed on the outside of the guide member 22, thereby further avoiding the problem of turbulence in the shell 10 and reducing the vibration and noise of the shell 10 during the guide process.

[0060] When the driving member 21 drives one of the guide members 22 to rotate, the other guide members 22 are engaged with each other in the form of transmission. By setting the rotational circumference of each guide member 22, the rotational speed of each guide member 22 is adjusted, thereby adjusting the flow speed of the fluid at different positions in the regulating chamber 13.

[0061] In one embodiment, the circumference of the outer periphery of the guide member 22 near the two sides of the shell 10 can be made greater than the circumference of the outer periphery of the guide member 22 at the middle position of the shell 10, so as to improve the guiding effect of the guide member 22 near the two sides of the shell 10 on the fluid, and control most of the fluid to be discharged from the air inlet 11 to the regulating cavity 13 on both sides of the shell 10, thereby increasing the movement path of the fluid in the regulating cavity 13, avoiding the fluid from flowing directly in a straight line along the air inlet 11 to the air outlet 12, thereby reducing the vibration and noise of the shell 10 during the fluid diversion process.

[0062] In one embodiment, the guide member 22 with a longer circumference on the periphery and the guide member 22 with a shorter circumference on the periphery can be spaced apart in the adjusting cavity 13 to adjust the guiding effect of the meshing area between two adjacent guide members 22 on the fluid. The specific spacing setting form can be adjusted by those skilled in the art according to actual usage conditions to the guiding effect at different positions of the adjusting cavity 13 in the shell 10.

[0063] refer to Figure 1As shown, two guide members 22 can be provided. In the present embodiment, two adjacent guide members 22 are meshed and driven in the form of gears. The driving member 21 only needs to drive one guide member 22 to rotate, and the other guide members 22 can guide the fluid in a follow-up manner. The driving member 21 drives the two guide members 22 to rotate, so that the two guide members 22 can release the gas to both sides of the shell 10, so that the fluid flows through the regulating cavity 13 surrounded by the outer side surface of the guide member 22 and the side surface of the shell 10. Since the outer side surface of the guide member 22 is arc-shaped, the fluid flows in an arc-shaped airflow channel formed close to the outer side surface of the guide member 22, thereby reducing the turbulence problem of the fluid during the flow, and effectively reducing the vibration and noise of the shell 10 during the diversion process.

[0064] Preferably, the circumferences of the two guide members 22 can be made equal, and the number of meshing teeth of the meshing structure 25 can be the same, so that the driving member 21 drives the two guide members 22 to guide the fluid at the same speed, so that the flow speed of the fluid on both sides of the shell 10 is the same, further reducing the turbulence problem of the fluid during the flow process, and effectively reducing the vibration and noise of the shell 10 during the diversion process.

[0065] refer to Figure 2 As shown, in the present embodiment, two guide members 22 are provided, and the structure of the guide member 22 can be provided as a fan structure. After the driving member 21 drives one fan to rotate, due to the meshing transmission of the blades of the two fans, the driving member 21 only needs to drive one fan to rotate, and the other fan can guide the fluid in a follow-up manner. The driving member 21 drives the two fans to rotate, so that the two fans can release the gas to both sides of the shell 10, so that the fluid flows through the regulating chamber 13 surrounded by the outer side surface of the fan and the side surface of the shell 10, thereby reducing the turbulence problem of the fluid during the flow process, and effectively reducing the vibration and noise of the shell 10 during the diversion process.

[0066] It should be noted that the fan blades have sufficient meshing strength and mechanical strength so that after the driving member 21 can drive one fan to rotate, the other meshing transmission fan can rotate synchronously to drive the fluid to be diverted.

[0067] refer to Figure 3 As shown, the guide members 22 are provided with three, referring to Figure 4 As shown, four guide members 22 are provided. By providing a plurality of guide members 22, the guide effects at different positions in the regulating cavity 13 are adjusted, thereby improving the flexibility during use.

[0068] Preferably, the circumference of the outer periphery of the guide member 22 near the two sides of the shell 10 can be made greater than the circumference of the outer periphery of the guide member 22 at the middle position of the shell 10, so as to improve the guiding effect of the guide member 22 near the two sides of the shell 10 on the fluid, and control most of the fluid to be discharged from the air inlet 11 to the regulating cavity 13 on both sides of the shell 10, thereby increasing the movement path of the fluid in the regulating cavity 13, avoiding the fluid from flowing directly in a straight line along the air inlet 11 to the air outlet 12, thereby reducing the vibration and noise of the shell 10 during the fluid diversion process.

[0069] In one embodiment, the guide member 22 with a longer circumference on the periphery and the guide member 22 with a shorter circumference on the periphery can be spaced apart in the adjusting cavity 13 to adjust the guiding effect of the meshing area between two adjacent guide members 22 on the fluid. The specific spacing setting form can be adjusted by those skilled in the art according to actual usage conditions to the guiding effect at different positions of the adjusting cavity 13 in the shell 10.

[0070] In actual use, the circumference ratio of the longer circumference flow guide member 22 to the shorter circumference flow guide member 22 can be adjusted so that the flow guide speed of the longer circumference flow guide member 22 on both sides of the shell 10 meets the use requirements.

[0071] refer to Figure 1 and Figure 2 As shown, according to an embodiment of the present application, the flow guide mechanism 20 includes a shielding area 26 and two flow guides 22, the two flow guides 22 are meshed for transmission, the shielding area 26 is the meshing transmission area between the two flow guides 22, and the driving member 21 drives one of the flow guides 22 to rotate so that the fluid is guided out of the regulating chamber 13 outside the shielding area 26. The driving member 21 drives one of the flow guides 22 to guide the regulating chambers 13 on both sides of the housing 10, that is, the two flow guides 22 drive the fluid to be guided from the shielding area 26 to the regulating chambers 13 on both sides of the housing 10.

[0072] The shielding area 26 can be made to correspond to the position of the air inlet 11, so that the fluid can escape to the outside of the shielding area 26, so as to increase the movement path of the fluid in the regulating chamber 13, avoid the fluid from flowing directly in a straight line along the air inlet 11 to the air outlet 12, and thereby reduce the vibration and noise of the shell 10 during the fluid diversion process.

[0073] Furthermore, the shielding area 26 can be arranged in the middle of the shell 10 to fully utilize the guiding effect of the guiding mechanism 20 on the fluid, forming an arc-shaped air flow channel on both sides of the shell 10, thereby avoiding turbulence of the fluid in the regulating chamber 13.

[0074] refer to Figure 1 and Figure 2 As shown, according to one embodiment of the present application, the guide member 22 includes a shaft portion 221 and a plurality of guide portions 222 , and the plurality of guide members 22 are circumferentially spaced apart and arranged on the circumferential side of the shaft portion 221 , and adjacent guide members 22 are meshed and transmitted through the guide portions 222 .

[0075] The shaft 221 of one of the guide members 22 is axially connected to the driving member 21, and the shaft 221 is driven to rotate by the driving member 21 to rotate multiple guide members 22. The guide members 22 on two adjacent guide members 22 are meshed and transmitted to drive multiple guide members 22 to rotate synchronously through one driving member 21. The guide portion 222 has a certain radial extension length so that two adjacent guide members 22 can be meshed through the guide portion 22. The guide portion 222 can be set to a gear structure, and can also have a fan blade structure, thereby driving multiple guide members 22 to rotate, and the driving member 21 can be set to a motor.

[0076] According to an embodiment of the present application, a plurality of the guide parts 222 are arranged at equal intervals along the circumferential side of the shaft part 221, and a plurality of the guide parts 222 are arranged at equal intervals along the circumferential side of the shaft part 221 to improve the uniformity of the guide member 22 in the process of guiding the fluid. In one embodiment, the two guide members 22 have the same structure, so that the flow velocity and flow rate of the fluid in the regulating chamber 13 on both sides of the housing 10 are the same, so as to further improve the stability of the static pressure at the position of the air outlet 12.

[0077] According to an embodiment of the present application, one of the guide members 22 is a driving wheel, and the other guide member 22 is a driven wheel, the driving wheel and the driven wheel are meshed for transmission, and the shielding area 26 is a traditional meshing area between the driving wheel and the driven wheel.

[0078] The driving member 21 is connected to the driving wheel, and the driven wheel is meshed with the driving wheel for transmission. The driving wheel drives the driven wheel to rotate, and the shielding area 26 forms an arc-shaped air flow channel to guide the fluid to the regulating cavity 13 on both sides of the shell 10, thereby improving the movement path of the fluid in the regulating cavity 13, avoiding the fluid from flowing directly in a straight line from the air inlet 11 to the air outlet 12, thereby reducing the vibration and noise of the shell 10 during the fluid diversion process.

[0079] According to an embodiment of the present application, the housing 10 includes a guide plate 14, the guide plate 14 extends from the air inlet 11 to the air outlet 12, and a protrusion 141 is provided on the side of the guide plate 14 facing the air guide mechanism 20, so that the protrusion 141 forms a constriction 131 in the adjustment cavity 13. Figure 5-Figure 6As shown, the guide plate 14 is arranged on both sides of the shell 10, and the guide plate 14 is used to improve the stability of the fluid flowing in the regulating chamber 13. The guide plate 14 includes a protrusion 141, and the protrusion 141 protrudes toward one side of the guide mechanism 20 to form a constriction 131 in the regulating chamber 13. The constriction 131 increases the flow speed of the fluid and strengthens the guide effect of the guide mechanism 20 on the fluid.

[0080] The protrusion 141 moves from the side of the shell 10 where the air inlet 11 is located to the side of the shell 10 where the air outlet 12 is located, and extends along the circumference of the shell 10, so that the fluid adheres to the guide plate and flows from the air inlet 11 to the air outlet 12.

[0081] refer to Figure 6 As shown, according to an embodiment of the present application, the protrusion 141 is an arc-shaped plate protruding toward one side of the regulating chamber 13. The arc-shaped plate reduces the friction resistance between the fluid and the guide plate when the fluid flows to the protrusion 141, thereby increasing the fluid flow rate and reducing the vibration of the housing 10.

[0082] According to one embodiment of the present application, the regulating chamber 13 comprises:

[0083] An air inlet cavity 132 is disposed between the air inlet 11 and the constriction 131 so that airflow is introduced into the constriction 131 through the air inlet cavity 132;

[0084] The air outlet cavity 133 is disposed between the constriction 131 and the air outlet 12 , so that the airflow is introduced into the air outlet cavity 133 through the constriction 131 .

[0085] In one embodiment, the volume of the air inlet chamber 132 is smaller than the volume of the air outlet chamber 133, so as to improve the confluence effect of the air outlet chamber 133 on the fluid after guidance, balance the fluid flow rate in the air flow channel formed between multiple guide members 22 and between the guide members 22 and the shell 10, and improve the stability of the static pressure at the air outlet 12.

[0086] According to one embodiment of the present application, the guide plate 14 comprises:

[0087] The first confluence portion 142 faces the air inlet cavity 132 and is connected to one end of the protrusion 141 so that the airflow is introduced from the air inlet 11 through the first confluence portion 142 into the constriction 131;

[0088] The second confluence portion 143 faces the air outlet cavity 133 and is connected to the other end of the protrusion 141 , so that the airflow is introduced into the air outlet cavity 133 through the second confluence portion 143 .

[0089] refer to Figure 7 As shown, the first confluence portion 142 is an arc-shaped plate member recessed toward one side of the regulating chamber 13, so that the airflow is introduced from the air inlet 11 into the constriction 131 through the first confluence portion 142. The second confluence portion 143 is also an arc-shaped plate member recessed toward one side of the regulating chamber 13, so that the airflow is introduced into the air outlet chamber 133 through the second confluence portion 143. Through the first confluence portion 142, the second confluence portion 143 and the protrusion 141, the fluid close to the two sides of the shell 10 can flow in contact with the guide plate 14 and finally merge with the fluid in the regulating chamber 13 in the air outlet chamber 133. Through the air outlet chamber 133, the flow velocity of the fluid at each position is further balanced, and the static pressure at the position of the air outlet 12 is further stabilized.

[0090] refer to Figure 8-Figure 9 As shown, in any of the above embodiments, the air guide mechanism 20 further includes a transmission 24, and the driving member 21 is transmission-connected to the air guide mechanism 20 via the transmission 24. The output power of the driving member 21 is adjusted by the transmission 24, and then the rotation speed of the plurality of air guide members 22 in the air guide mechanism 20 is adjusted to adjust the static pressure value at the air outlet 12.

[0091] Preferably, the transmission 24 is a continuously variable transmission 24 , and thus, the user can flexibly adjust the static pressure at the air outlet 12 according to actual usage conditions.

[0092] According to an embodiment of the present application, the flow guiding mechanism 20 includes a control member 23, which is disposed at the air outlet 12 and is used to detect the static pressure value of the air outlet 12, and the control member 23 is electrically connected to the driving member 21. Further, the control member 23 includes a sensor, a processor and a controller, so that the sensor detects the static pressure value at the air outlet 12, compares and judges the static pressure value at the air outlet 12 with the range of preset static pressure values ​​in the processor, and when the static pressure value at the air outlet 12 meets the preset range, sends an instruction to the controller, and sends an instruction to the driving member 21 through the controller to adjust the power output efficiency of the driving member 21, thereby adjusting the flow guiding effect of the flow guiding mechanism 20 on the fluid in the regulating chamber 13.

[0093] The sensor is a static pressure sensor, which is disposed at the air outlet 12 to detect the static pressure value at the air outlet 12 .

[0094] refer to Fig.10As shown, in one embodiment, the movement speed of the driving wheel and the driven wheel is variable, that is, the static pressure outside the air outlet 12 is also variable. A preset static pressure value can be set first, and the continuously variable transmission 24 will adjust the speed. When the motor is running, the continuously variable transmission 24 will make the driving wheel run to the corresponding speed so that the air supply at the air outlet 12 reaches the desired static pressure.

[0095] When it is detected that the static pressure coming out of the air outlet 12 deviates from the target static pressure value, the air outlet 12 is equipped with a static pressure sensor for detecting the static pressure of the air outlet 12. If there is a deviation, it will be fed back to the continuously variable transmission 24, and the gear speed will be adjusted again to correct the static pressure of the air outlet 12. The sensor will feed back the detected data again and make continuous corrections to make the final static pressure stable and at the expected value.

[0096] According to an embodiment of the present application, the housing 10 includes a silencer 15, which is disposed inside the housing 10. The silencer 15 further reduces the noise during the fluid diversion process in the housing 10, and at the same time, effectively reduces the vibration of the housing 10.

[0097] According to another aspect of the present application, an air conditioning unit is provided, comprising the static pressure regulating assembly described in any one of the above embodiments.

[0098] refer to Fig.11 and Fig.12 As shown, according to an embodiment of the present application, the air conditioning unit includes a heat exchanger 30, and the heat exchanger 30 is arranged at the air inlet 11 to exchange heat with the fluid through the heat exchanger 30. Then, the heat exchanger 30 is used to exchange heat with the gas entering the regulating chamber 13. For example, the heat exchanger 30 is set as a surface cooler, and the fluid after heat exchange is guided by the guide mechanism 20 to improve the heat exchange efficiency.

[0099] As an example, this cabinet type gear coil air conditioner unit has panels in six directions with sound absorbing cotton glued on them for absorbing noise, and is equipped with a surface cooler and a guide plate 14 inside. The surface cooler is placed at the air inlet 11 to cool the incoming wind, and the power of the incoming wind comes from the movement of the gears. There are two gears, namely the driving gear and the driven gear and their respective gear shafts. The driving gear shaft is driven by the stepless transmission 24 on the top of the unit, and the stepless transmission 24 is driven by the motor on the unit.

[0100] Here we will explain the principle of how the meshing movement of gears can deliver air. The movement direction of the active gear is clockwise. This movement direction causes the meshing of the two gears to always disengage in the direction of the cooler (equivalent to the heat exchanger 30). This small space becomes larger, causing the pressure in this place to decrease, and the air with a higher pressure outside the cooler will be pressed in. Two air passages (equivalent to the regulating chamber 13) are formed between the guide plate 14 and the gear. After the wind comes in, it passes through these two passages, gathers behind the gear (equivalent to the air outlet chamber 133), and goes out from the air outlet 12.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
