Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically, to a flow valve and an air conditioner. Background Technology

[0002] In the field of air conditioning, when dehumidification is required, the condenser needs to deliver refrigerant to the evaporator. The evaporator then fully utilizes the heat absorption properties of the refrigerant to lower the indoor temperature, thereby achieving the dehumidification effect.

[0003] However, in existing technologies, the flow valve in air conditioners can only control the flow or shut-off of refrigerant, resulting in only two dehumidification modes: dehumidification mode and non-dehumidification mode. Users can only control the on / off state of the dehumidification mode, and cannot control the degree of dehumidification. Even when only a slight dehumidification is needed, the entire dehumidification system must be fully activated, leading to wasted air conditioning energy. Summary of the Invention

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] Please refer to Figures 1 to 3 In the diagram, the X direction represents the left-right direction. The arrows in the diagram indicate the refrigerant flow direction. This application provides a flow valve for controlling the flow rate of refrigerant. The flow valve includes: a flow control component, which internally has a receiving cavity 100 and multiple branch channels 180, all of which are connected to the receiving cavity 100. A slider 130 is disposed within the receiving cavity 100, and the slider 130 is used to move within the receiving cavity 100 to control the number of branch channels 180 connected to the receiving cavity 100. The slider 130 also divides the receiving cavity 100 into a first receiving cavity 110 and a second receiving cavity 120 that are not interconnected. A pressure control component is used to control the pressure ratio between the first receiving cavity 110 and the second receiving cavity 120, so as to drive the slider 130 to move within the receiving cavity 100 by changing the pressure ratio.

[0022] For details, please continue to refer to Figure 1 The flow channel 180 includes a first flow channel 181, a second flow channel 182, and a third flow channel 183, all of which are located at the lower end of the receiving cavity 100. The slider 130 also includes a first baffle 150, which divides the receiving cavity 100 into a first receiving cavity 110 and a second receiving cavity 120 that are isolated from each other. By changing the pressure ratio between the first receiving cavity 110 and the second receiving cavity 120 using the pressure control component, the slider 130 can move left and right along the inner wall of the receiving cavity 100 under pressure.

[0023] Please refer to Figure 2 When the pressure in the second receiving cavity 120 is greater than the pressure in the first receiving cavity 110, the slider 130 will move from right to left, reaching the position shown in the figure. At this point, the slider 130 blocks the passage between the first receiving cavity 110 and the first branch channel 181, thereby reducing the total flow rate of refrigerant flowing out of the branch channel 180. As the slider 130 continues to move to the left, the total amount of refrigerant flowing out of the branch channel 180 can be gradually reduced, or even completely blocked. In summary, this application can control the movement of the slider 130 by pressure, thereby adjusting the total amount of refrigerant flowing out of the branch channel 180. When the branch channel 180 of the flow valve of this application is connected to the evaporator 300, the degree of dehumidification of the air conditioner can be controlled by controlling the amount of refrigerant entering the evaporator 300.

[0024] In some embodiments, please refer to Figures 1 to 3 The flow control assembly also includes a second baffle 160 and a connecting rod 140. The slider 130 is movably disposed in the receiving cavity 100, and together with the slider 130, it defines a first receiving cavity 110. One end of the connecting rod 140 is connected to the second baffle 160, and the other end is connected to the slider 130. When the slider 130 moves, the second baffle 160 moves together with the slider 130 under the support of the connecting rod, so as to maintain the constant size of the space of the first receiving cavity 110.

[0025] In the actual use of the flow valve, when precise refrigerant flow control is required, such as reducing the flow rate to two-thirds of its original value, if the second baffle 160 is not installed, when the slider 130 moves to the left... Figure 2 As the space of the first receiving cavity 110 decreases, the pressure of the refrigerant in the first receiving cavity 110 will increase, which will lead to an increase in the flow velocity of the refrigerant. This may cause the flow rate of the refrigerant to be the same as or too small as before the slider 130 blocked the first diversion channel 181, so that the flow control is not equal to two-thirds. At the same time, the pressure change in the first receiving cavity 110 will also cause the slider 130 to move a shorter distance, requiring the second receiving cavity 120 to continuously increase the pressure to push the slider 130 to move, resulting in increased energy consumption. Furthermore, the gradual reduction in the volume of the first receiving cavity 110 may also cause the refrigerant in the diversion channel 180 to become blocked due to the rapid change in the flow area.

[0026] In summary, in this embodiment, a second baffle 160 is provided, and the second baffle 160 can move together with the slider 130 through the connecting rod 140. At this time, as the slider 130 moves to the left, the size of the first receiving cavity 110 remains unchanged, that is, the pressure can also remain unchanged, thereby improving the accuracy of the flow control of the flow valve, reducing the energy consumption of the flow valve or the air conditioner equipped with the flow valve, and avoiding refrigerant blockage.

[0027] In some embodiments, please refer to Figures 1 to 3 The flow control assembly also includes a spring 170, one end of which abuts against the second baffle 160, and the other end against the inner wall of the receiving cavity 100, for driving the baffle and slider 130 to reset. During the adjustment of the flow valve, the slider 130 often needs to move to the left to control the flow and then return to its original position, thereby keeping the flow valve in a state where the diversion channel 180 is fully connected to the first receiving cavity 110 when not in operation. At the same time, compared with using a motor and pressure control assembly to reset the slider 130, the reset of the spring 170 only requires the addition of a spring 170, and the reset function can be achieved without the need for additional mechanisms, thereby reducing the production cost of the flow valve.

[0028] In some embodiments, please refer to Figures 1 to 3 The pressure control assembly includes: a flow conduit 230, a main conduit 210, a flow restrictor, and a pressure dividing conduit 220. The flow conduit 230 is connected to the first receiving cavity 110; the pressure dividing conduit 220 is connected to the second receiving cavity 120; the flow restrictor is used to reduce the flow rate of the pressure dividing conduit 220 and / or the flow conduit 230 to control the pressure ratio of the first receiving cavity 110 and the second receiving cavity 120; one end of the main conduit 210 is supplied with gas or liquid, and the other end is connected to the flow conduit 230 and / or the pressure dividing conduit 220.

[0029] When both the flow conduit 230 and the pressure-reducing conduit 220 are connected to the main pipe 210, the flow restrictor reduces the refrigerant flow rate, thereby making the pressure of the refrigerant flowing into the first receiving cavity 110 lower than the pressure of the refrigerant in the second receiving cavity 120, thus achieving the effect of driving the slider 130 to move through pressure. It can be understood that the flow restrictor can also reduce the flow rate in the pressure-reducing conduit 220, thereby making the pressure in the second receiving cavity 120 lower than that in the first receiving cavity 110, achieving the reset or rightward movement of the slider 130. It can be understood that the flow restrictor includes a contraction assembly that reduces the pipe diameter, a continuously bent pipe, and a pipe with a diameter smaller than that of the pressure-reducing conduit 220 and the flow conduit 230, thereby achieving the effect of reducing the flow rate.

[0030] In some embodiments, please refer to Figures 1 to 3 If the flow-limiting component is a capillary tube 240, with one end connected to the main pipe 210 and the other end connected to the flow conduit 230, it is used to reduce the refrigerant flow rate. In this case, the diameter of the capillary tube 240 is smaller than that of the flow conduit 230. Therefore, when the flow conduit 230 is connected to the main pipe 210 via the capillary tube 240, it can effectively limit the flow. Compared to using a contraction assembly for flow limiting, directly using the capillary tube 240 for flow limiting reduces the production cost of the flow valve.

[0031] In some embodiments, please refer to Figures 1 to 3 The flow-limiting element is a capillary tube 240, which includes a first capillary tube 241 and a second capillary tube 242. The pressure-splitting conduit 220 includes a first pressure-splitting conduit 221 and a second pressure-splitting conduit 222. One end of the first pressure-splitting conduit 221 is connected to the main guide tube 210, and the other end is connected to the second receiving cavity 120. One end of the first capillary tube 241 is connected to the main guide tube 210, and the other end is connected to the second pressure-splitting conduit 222 and the second capillary tube 242. The second pressure-splitting conduit 222 is connected to the second receiving cavity 120. One end of the second capillary tube 242 is connected to the first capillary tube 241, and the other end is connected to the flow conduit 230. At this time, the pressure ratio of the first receiving cavity 110 and the second receiving cavity 120 can be controlled by controlling the connection or closure of the first and second pressure-splitting tubes.

[0032] For example, let the pressure inside the first pressure-sharing conduit 221 be P10, the pressure inside the second pressure-sharing conduit 222 be P20, and the pressure inside the flow conduit 230 be P30. Since the first pressure-sharing conduit 221 is directly connected to the main guide tube 210, the two ends of the second pressure-sharing conduit 222 are connected to the first capillary tube 241 and the second capillary tube 242 respectively, and the flow conduit 230 is connected to the second capillary tube 242, therefore P10 is greater than P20, which is greater than P30. At this time, based on the connection status of both the first and second pressure-sharing conduits 221 and 222 with the second receiving cavity 120, the pressure in the second receiving cavity 120 can be any one of P10+P20, P10, or P20. Specifically, when both the first and second pressure-sharing conduits 221 and 222 are connected, the pressure in the second receiving cavity 120 is P10+P20. When only the first pressure-sharing conduit 221 is connected, the pressure in the second receiving cavity 120 is P10. When only the second pressure-dividing conduit 222 is connected, the pressure in the second receiving cavity 120 is P20.

[0033] In summary, slider 130 has three moving speeds. If the first baffle 150 is not provided on the left side of slider 130, as slider 130 moves to the left, the space of the first receiving cavity 110 will decrease, meaning the pressure component of the first receiving cavity 110 will increase. At this time, the pressure of slider 130 can be measured... Figure 2 Location and Figure 3 The pressure in the first receiving cavity 110 at its current position is denoted as P31 and P32, respectively. By adjusting the size of the capillary tube 240, P10 + P20 equals P32, and P20 equals P31. Therefore, when only the second pressure-dividing conduit 222 of the second receiving cavity 120 is connected, the slider 130 is located at... Figure 2 At this position, the first branch channel 181 is blocked by the slider 130, reducing the amount of refrigerant allowed to flow through the flow valve. When the second receiving cavity 120 is connected to the first pressure dividing conduit 221 and the second pressure dividing conduit 222, the slider 130 is located at... Figure 3 At this position, both the second branch channel 182 and the first branch channel 181 are blocked by the slider 130, thus further reducing the amount of refrigerant allowed to pass through the flow valve. In other words, three-stage control of the flow valve is achieved, enabling the air conditioner equipped with the flow valve to have high, medium, and low dehumidification modes, thereby improving the energy efficiency of the air conditioner.

[0034] It is understandable that when the flow valve has a spring 170 and a first baffle 150, let the spring force of the spring 170 be F10, and the areas of the first baffle 150 and the second baffle 160 both be S. Let the rightward force on the first baffle 150 be F20 and the leftward force be F3, then the following relationship exists: F20 = F10 + P10 / S; F30 = P20 / S, or F30 = (P10 + P20) / S; As can be seen from the above embodiment, as the slider 130 moves, the spring 170 will continue to compress, and the elastic force F10 will increase. Let the slider 130 be located at... Figure 2 At the position shown, the elastic force of spring 170 is F11, and the following relationship exists: F20=F30=F10+P10 / S=P20 / S. At this time, only the second pressure dividing conduit 222 is connected to the second receiving cavity 120, the first diversion channel 181 is blocked by the slider 130, and the flow rate allowed by the flow valve is relatively small.

[0035] Let slider 130 be located at Figure 3 At the position shown, its elastic force is F12, and the following relationship exists: F20=F30=F12+P10 / S=(P10+P20) / S. At this time, the first pressure dividing conduit 221 and the second pressure dividing conduit 222 are both connected to the second receiving cavity 120. The first diversion channel 181 and the second diversion channel 182 are both blocked by the slider 130, and the flow rate allowed by the flow valve is the minimum.

[0036] Furthermore, the pressure ratio between the first receiving cavity 110 and the second receiving cavity 120 is (0.3~0.75):1. At this time, the acceleration and speed of the slider 130 when sliding are appropriate, which can avoid the slider 130 moving too fast and shaking off or moving too slowly and causing the dehumidification mode switching time to be too long.

[0037] When both the first pressure dividing conduit 221 and the second pressure dividing conduit 222 are blocked, that is, when the pressure control component is in a non-working state, the slider 130 is located under the action of the spring 170. Figure 1 At the position shown, the flow rate allowed by the flow valve is at its maximum. In summary, this embodiment of the application can achieve control of the flow valve at three positions by connecting and disconnecting the first pressure-dividing conduit 221 and the second pressure-dividing conduit 222.

[0038] In some embodiments, please refer to Figures 1 to 3 The pressure control component also includes an electromagnetic structure 250, which can be a solenoid valve used to control the connection or disconnection of the pressure-distributing conduit 220 to control the pressure ratio between the first receiving chamber 110 and the second receiving chamber 120. The electromagnetic structure 250 controls the connection or disconnection of the pressure-distributing conduit 220 by electromagnetically controlling a magnetic slider 130 to compress the pressure-distributing conduit 220. Alternatively, the electromagnetic structure 250 may include a transfer chamber with at least one flow port at its upper end and a flow pipe at its lower end, connected to the second receiving chamber 120, and the flow port connected to the pressure-distributing conduit. In this case, the electromagnetic structure 250 can control the connection or disconnection between the pressure-distributing conduit 220 and the second receiving chamber 120 by controlling the magnetic slider 130 to block the flow port. Please refer to [further details to be added]. Figure 1 When there are multiple pressure-dividing conduits 220, the number of flow ports can be the same as the number of pressure-dividing conduits 220, and the pressure-dividing conduits 220 and the flow ports correspond one-to-one. At this time, the high, medium and low gears of the flow valve can be switched by controlling the slider 130 to move.

[0039] In some embodiments, please refer to Figure 1 The direction of movement of slider 130 is the length direction, and the number of branch channels 180 is N, where N is greater than 2; The length of slider 130 is greater than the sum of the lengths of N-1 branch channels 180. The length of slider 130 is... Figure 1 As shown in the diagram, the sum of the lengths of the N-1 branch channels 180 is B. If A is less than B, then when slider 130 is located... Figure 2 When A is greater than or equal to B, slider 130 will not be able to simultaneously block the first branch channel 181 and the second branch channel 182, thus preventing slider 130 from accurately adjusting the position of the flow valve. Only when A is greater than or equal to B can slider 130 simultaneously block multiple branch channels 180, thereby achieving precise multi-position control of the flow valve. Please refer to [the relevant documentation / reference]. Figure 1 The sum of the lengths of the N-1 branch channels 180 should be understood as including the diameter of the branch channel 180 and the distance between adjacent branch channels 180.

[0040] Please refer to Figure 2 and Figure 3 This application also provides an air conditioner, which includes a condenser 500, a flow valve, an evaporator 300, and a compressor 400. The condenser 500 is used to convert refrigerant gas into refrigerant, and is connected at one end to the compressor 400 and at the other end to the flow valve. The evaporator 300 is connected at one end to the flow valve and at the other end to the compressor 400. The flow valve is located between the evaporator 300 and the condenser 500 and is used to control the flow rate of the refrigerant. At this time, the compressor 400 can provide power to the refrigerant.

[0041] In some embodiments, please refer to Figures 1 to 3 The number of evaporators 300 corresponds to the number of branch channels 180; each branch channel 180 is connected to a corresponding evaporator 300. The branch channels 180 include a first branch channel 181, a second branch channel 182, and a third branch channel 183. The evaporators 300 include a first evaporator 310, a second evaporator 320, and a third evaporator 330. The first branch channel 181, the second branch channel 182, and the third branch channel 183 are respectively connected to the first evaporator 310, the second evaporator 320, and the third evaporator 330. Compared to multiple branch channels 180 connected to a single evaporator 300, this embodiment of the application allows for changing the size of multiple evaporators 300 to alter the dehumidification effect corresponding to high, medium, and low settings during air conditioning dehumidification, and also facilitates the individual maintenance and disassembly of the evaporators 300.
