Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an electric two-way valve used for an air conditioner and the air conditioner. Background Art

[0002] At present, the two-way valve includes a valve body, a valve core arranged in the valve body, and a transmission structure connected to the valve core and extending outside the valve body. The movement of the valve core is controlled by the transmission structure to realize the on-off of the two-way valve. For example, in a two-way valve with a valve core moving up and down, the valve core is connected to a valve stem, and the valve stem extends to the outside of the valve body and is connected to a handwheel. When the handwheel rotates, the valve stem moves up and down, thereby driving the valve core to move up and down to realize the on-off of the two-way valve. As the working time of this two-way valve increases, the working medium is prone to leakage at the joint between the valve stem and the valve body, which affects the use of the two-way valve and thus affects the user experience.

[0053] Figure 1 is a schematic structural diagram of an electric two-way valve according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 5 The embodiment of the utility model provides an electric two-way valve 10 for an air conditioner, comprising a valve body 100, a valve core 200 and an electromagnet 300. The valve body 100 has a valve core cavity, and a first connecting port 102 and a second connecting port 101 are arranged on the cavity wall of the valve core cavity. The valve core 200 is movably installed in the valve core cavity to move to a first position, or to a second position where the first connecting port 102 and the second connecting port 101 are connected, or to a third position between the first position and the second position. The valve core 200 is configured to move under the action of a magnetic force. The electromagnet 300 is arranged on the valve body 100, and the electromagnet 300 is configured to generate a suction force on the valve core 200 after being energized to generate magnetism, so that the valve core 200 moves from the first position to the second position.

[0054] After the electromagnet 300 is energized, it generates magnetic force to drive the valve core 200 to move. The valve core 200 moves from the first position to the second position, and has at least three working positions. In the first position, the valve core 200 disconnects the connection between the first connecting port 102 and the second connecting port 101. In the second position, the valve core 200 connects the first connecting port 102 and the second connecting port 101. In the third position, the valve core 200 enables the valve body 100 to transport the refrigerant at a certain flow rate, which is less than the maximum flow rate of the first connecting port 102 and the second connecting port 101. That is, the valve core 200 can adjust the flow rate of the refrigerant transported by the valve body 100. In the above setting, the valve core is set in the valve core cavity and moves by magnetic force. No other transmission structure is required. In addition to the first connecting port and the second connecting port, the valve body does not need to open other installation ports, thereby eliminating the leakage problem in the prior art and improving the user experience.

[0055] In some alternative embodiments of the present invention, the electromagnet 300 is configured to generate a suction force on the valve core 200 after being energized to generate magnetism, so that the valve core 200 moves from the second position to the first position.

[0056] In some embodiments of the present invention, Figures 1 to 3 As shown, the valve core 200 is a spherical valve core 200 .

[0057] The provision of the spherical valve core 200 can reduce the resistance to the fluid in the valve core cavity, and the spherical valve core 200 is in line contact with the valve core cavity, so the sealing effect is better and there will be no internal leakage of the medium after sealing.

[0058] In some embodiments of the present invention, the spherical valve core 200 is made of magnetic material. Magnetic material refers to a material with magnetism, including iron, cobalt, nickel, neodymium iron boron, ferrite, etc. These materials can be magnetized under the action of an external magnetic field and generate a magnetic field themselves. This arrangement allows the spherical valve core 200 to move under the action of the magnetic force after the electromagnet 300 is energized to generate magnetism.

[0059] In some alternative embodiments of the present invention, the spherical valve core 200 is a magnet. A magnet refers to an object that is processed and assembled from magnetic materials to have a certain shape and a specified magnetic direction and can generate a stable magnetic field.

[0060] In some alternative embodiments of the present invention, the spherical valve core 200 includes a spherical shell and an adsorbing member disposed in the spherical shell, and the adsorbing member is made of a magnetic material, or the adsorbing member is a magnet. That is, after the electromagnet 300 is energized to generate magnetism, the built-in adsorbing member and the electromagnet 300 generate magnetic force to drive the spherical valve core 200 to move.

[0061] In some embodiments of the present invention, the valve body 100 includes a first valve body portion 110 and a second valve body portion 120 . The first valve body portion 110 is installed on the second valve body portion 120 . The first valve body portion 110 and the second valve body portion 120 cooperate to define a closed valve core cavity.

[0062] In these embodiments, the valve body 100 is a two-body arrangement, and the first valve body portion 110 is installed on the second valve body portion 120 to jointly define a valve core cavity. Compared with the valve body 100 being integrally formed, this arrangement facilitates the installation of the valve core 200, and the valve core 200 is first installed in the first valve body portion 110, and then the second valve body portion 120 is installed, or the valve core 200 is first installed in the second valve body portion 120, and then the first valve body portion 110 is installed. This arrangement also facilitates the realization of a sealing effect, preventing refrigerant leakage, especially preventing the leakage of explosive refrigerants.

[0063] Furthermore, in some embodiments of the present invention, the first valve body portion 110 has a first valve core cavity portion, the second valve body portion 120 has a second valve core cavity portion, and the first valve core cavity portion and the second valve core cavity portion are arranged opposite to each other to form a valve core cavity.

[0064] In some embodiments, the first valve body portion 110 and the second valve body portion 120 are identical, which can reduce processing costs.

[0065] In some alternative embodiments of the present invention, Figure 2 As shown, the first valve body 110 has a valve core cavity and an installation opening communicating with the valve core cavity, and the second valve body 120 closes the installation opening.

[0066] In these embodiments, the first communication port 102, the second communication port 101 and the installation opening are all arranged on the side wall of the first valve body 110. When installing the valve core 200, the valve core 200 is first installed in the first valve body 110, and then the second valve body 120 is installed at the installation opening to close the installation opening. After the valve core 200 is installed in place, the second valve body 120 can be used to close the installation opening.

[0067] In some alternative embodiments of the present invention, the second valve body portion 120 has a valve core cavity and an installation opening communicating with the valve core cavity. The first valve body portion 110 closes the installation opening.

[0068] In these embodiments, the first communication port 102, the second communication port 101 and the installation opening are all disposed on the side wall of the second valve body 120. When installing the valve core 200, the valve core 200 is first installed in the second valve body 120, and then the first valve body 110 is installed at the installation opening to close the installation opening.

[0069] Of course, in some embodiments of the present invention, the valve body 100 may also be integrally formed, which can save manufacturing and installation costs of the valve body 100 .

[0070] In some embodiments of the present invention, Figures 1 to 3 As shown, the electromagnet 300 is arranged outside the valve body 100. Being arranged outside is convenient for both installation and maintenance of the electromagnet 300.

[0071] In some embodiments of the utility model, the electric two-way valve further includes a reset device, which is disposed in the valve core cavity. The direction of the force provided by the reset device to the valve core 200 is opposite to the direction of the force provided by the electromagnet 300 to the valve core 200.

[0072] The reset device is used to reset the valve core 200. For example, the valve core 200 moves from the first position to the second position under the action of the magnetic force of the electromagnet 300, that is, the valve body 100 changes from the disconnected state between the first communication port 102 and the second communication port 101 to the connected state between the first communication port 102 and the second communication port 101. When the valve body 100 does not need to transport refrigerant, the electromagnet 300 is not energized, the magnetism disappears, the magnetic force disappears, and the valve body 100 moves from the second position to the first position under the action of the reset device, and the valve body 100 changes from the connected state between the first communication port 102 and the second communication port 101 to the disconnected state between the first communication port 102 and the second communication port 101. Of course, the reset device can also move the valve core 200 from the third position to the first position.

[0073] In some embodiments of the present invention, Figures 1 to 3 As shown, the reset device is a compression spring 400 , one end of the compression spring 400 is fixedly connected to the valve body 100 , and the other end of the compression spring 400 is fixedly connected to the valve core 200 .

[0074] The elastic force of the compression spring 400 is used to provide resistance to the attraction between the valve core 200 and the electromagnet 300. The electromagnet 300 is energized to generate magnetic force, so that the valve core 200 moves under the action of the magnetic force and compresses the compression spring 400. When the electromagnet 300 is not energized, the magnetism disappears, the magnetic force disappears, and the valve body 100 moves in the opposite direction under the action of the compression spring 400. Further, the valve core 200 can be controlled to be in the second position or the third position by adjusting the current of the electromagnet 300. When the flow rate of the refrigerant needs to be adjusted, the current of the electromagnet 300 can be set, and when the valve core 200 is in the third position, the elastic force of the compression spring 400 is equal to the magnetic force. When it is necessary to fully connect the first connecting port 102 and the second connecting port 101, the current of the electromagnet 300 can be increased, and the valve core 200 moves to the second position and moves to the second position.

[0075] In some alternative embodiments of the present invention, the compression spring 400 may only be in contact with the valve core 200 without being connected. That is, during the movement of the valve core 200, the valve core 200 may roll. As a result, the sealing surface of the spherical valve core 200 each time in the first position will be at a different position of the sphere, which can reduce the wear of the spherical valve core 200 and extend its service life. Moreover, the arrangement that the spherical valve core 200 is not connected to the compression spring 400 also facilitates the installation and manufacture of the electric two-way valve.

[0076] In some alternative embodiments of the utility model, the reset device may also be a tension spring. The tension spring may be located on the side of the valve core 200 away from the electromagnet 300. When the electromagnet 300 is energized and generates magnetism, the attraction between the valve core 200 and the electromagnet 300 overcomes the pulling force of the tension spring and moves from the first position to the third position or the second position, thereby realizing the opening and closing of the first communication port 102 and the second communication port 101 or adjusting the flow of the refrigerant.

[0077] In some embodiments of the present invention, Figure 1 As shown, a bracket 500 is provided in the valve core cavity, the bracket 500 is fixedly connected to the cavity wall of the valve core cavity, and the compression spring 400 is installed on the bracket 500. The bracket can be a frame body, which does not affect the flow of the refrigerant. It can also be a plate.

[0078] Further, in some embodiments of the present invention, Figure 1 As shown, the bracket is in a plate shape, and a connecting hole 501 is opened on the bracket. The refrigerant flows through the connecting hole 501 to connect the first connecting port and the second connecting port.

[0079] In some embodiments of the present invention, Figure 3 As shown, a partition 600 is provided in the valve core cavity, and a third communication port 601 is provided on the partition 600. The valve core 200 is configured to open or close the third communication port 601. The first communication port 102 is connected to the second communication port 101 via the third communication port 601. The provision of the partition 600 is conducive to the sealing of the valve core 200. The spherical valve core 200 can move to the partition 600 to close the third communication port 601, and can also move away from the partition 600 to open the third communication port 601.

[0080] In some embodiments of the present invention, Figure 1As shown, the opening at one end of the valve core cavity is the first communication port 102. The opening at the other end of the valve core cavity is the second communication port 101. The area of ​​the maximum cross section of the valve core 200 is larger than the area of ​​the opening at one end of the valve core cavity, and the area of ​​the maximum cross section of the valve core 200 is smaller than the area of ​​the opening at the other end of the valve core cavity. In other words, the opening at one end of the valve core cavity is smaller than the opening at the other end of the valve core cavity. When the valve core 200 moves to the opening at one end of the valve core cavity, since the area of ​​the maximum cross section of the valve core 200 is larger than the area of ​​the opening at one end of the valve core cavity, the opening at one end of the valve core cavity is blocked, thereby disconnecting the first communication port 102 and the second communication port 101. This arrangement is conducive to the installation of the valve core 200. When installing the valve core 200, the valve core 200 is installed into the valve core cavity from the second communication port 101. Obviously, this arrangement is more conducive to the sealing between the valve core 200 and the valve core cavity.

[0081] In an alternative embodiment of the present invention, one end opening of the valve core cavity is communicated with the first communication port 102 .

[0082] Further, in some embodiments of the utility model, the valve core cavity includes a gradually expanding channel, and one end opening of the gradually expanding channel is an end opening of the valve core cavity. The other end opening of the gradually expanding channel is an end opening of the valve core cavity. In some embodiments, the valve core cavity is truncated cone-shaped. The small end of the truncated cone is the opening of one end of the valve core cavity, and the large end of the truncated cone is the opening of the other end of the valve core cavity. The spherical valve core 200 is arranged in the gradually expanding channel and slides or rolls in the gradually expanding channel. When the spherical valve core 200 slides or rolls to the side of the small end of the truncated cone, the first connecting port 102 and the second connecting port 101 are disconnected. Of course, in other embodiments, the cross-section of the gradually expanding channel is not circular, and the maximum cross-sectional profile of the valve core 200 can be set to be consistent with the cross-sectional profile of the gradually expanding channel at a certain position. When the valve core 200 moves to this position, the first connecting port 102 and the second connecting port 101 are disconnected.

[0083] In an alternative embodiment of the present invention, the other end opening of the gradually expanding channel is connected to the other end opening of the valve core chamber via the communication channel. The area of ​​the maximum cross section of the valve core 200 is smaller than the area of ​​the other end opening of the gradually expanding channel, and the area of ​​the maximum cross section of the valve core 200 is smaller than the area of ​​the minimum cross section of the communication channel.

[0084] In some embodiments of the present invention, the cavity wall of the valve core cavity includes an end wall disposed between the first communication port 102 and the second communication port 101, a fourth communication port is disposed on the end wall, one end opening of the valve core cavity is the fourth communication port, and the valve core 200 is configured to open or close the fourth communication port. The function of the end wall is similar to that of the partition 600, both of which are conducive to the sealing of the valve core 200. The spherical valve core 200 can move to the end wall to close the fourth communication port to disconnect the first communication port 102 and the second communication port 101, and can also move away from the end wall to open the fourth communication port to connect the first communication port 102 and the second communication port 101.

[0085] The utility model also provides an air conditioner, comprising a first indoor unit, a second indoor unit, and an electric two-way valve and a three-way pipe of any of the above embodiments. The first indoor unit has a first evaporator. The second indoor unit has a second evaporator. The three-way pipe includes an inlet for the refrigerant to enter and a first outlet and a second outlet connected to the inlet, the first outlet is connected to the inlet of the first evaporator, and the second outlet is connected to the inlet of the second evaporator. The electric two-way valve is arranged between the first outlet and the inlet of the first evaporator.

[0086] The air conditioner here has at least two indoor units, and the refrigerant enters from the inlet of the three-way pipe and flows out from the first outlet and the second outlet respectively, and enters the corresponding first evaporator and the second evaporator to achieve heat exchange with the airflow flowing through the surface of the first evaporator and the airflow flowing through the surface of the second evaporator. The electric two-way valve is arranged between the first outlet and the inlet of the first evaporator to achieve control of the working state of the first indoor unit.

[0087] In an alternative embodiment of the present invention, the electric two-way valve is arranged between the second outlet and the inlet of the second evaporator.

[0088] The utility model also provides an air conditioner, such as Figure 4 As shown, the air conditioner includes an indoor unit 70, a condenser 20, a compressor 30, a four-way reversing valve 40, a gas-liquid separator 50, a throttle valve 60, a three-way pipe and an electric two-way valve 10 of any of the above embodiments. The indoor unit 70 has a first air supply duct and a second air supply duct, a first evaporator 71 is arranged in the first air supply duct, and a second evaporator 72 is arranged in the second air supply duct. The three-way pipe includes an inlet for the refrigerant to enter and a first outlet and a second outlet connected to the inlet, the first outlet is connected to the inlet of the first evaporator 71, and the second outlet is connected to the inlet of the second evaporator 72. In some embodiments, the electric two-way valve 10 is arranged between the first outlet and the inlet of the first evaporator, the second connecting port 101 is connected to the first outlet through a pipeline, and the first connecting port 102 is connected to the inlet of the first evaporator through a pipeline.

[0089] After being compressed by the compressor, the refrigerant enters the condenser 20 in the form of high-temperature and high-pressure gas through the gas-liquid separator 50 and the four-way reversing valve 40. When flowing out of the condenser, the refrigerant becomes liquid and enters the throttle valve, and then enters the inlet of the three-way pipe in the form of low-temperature and low-pressure gas, and flows out from the first outlet and the second outlet respectively, and enters the corresponding first evaporator 71 and the second evaporator 72 to achieve heat exchange with the airflow flowing through the surface of the first evaporator and the airflow flowing through the surface of the second evaporator. The electric two-way valve 10 is arranged between the first outlet and the inlet of the first evaporator to realize the on-off of the supply of refrigerant to the first evaporator.

[0090] In an alternative embodiment of the present invention, the electric two-way valve 10 is disposed between the second outlet and the inlet of the second evaporator 72 , the second communication port 101 is communicated with the second outlet through a pipeline, and the first communication port 102 is communicated with the inlet of the second evaporator 72 through a pipeline.

[0091] In some embodiments of the present invention, Figure 5 As shown, the indoor unit further includes a housing 80 and an air mixing fan 86. The housing 80 has a first air supply duct 81 and a second air supply duct 82, and an air mixing inlet 85 is provided on the front wall of the housing 80, wherein the first air supply duct 81 and the second air supply duct 82 are sequentially arranged along the width direction of the housing 80, a first connecting port 83 is provided on the side wall of the first air supply duct 81 facing the second air supply duct 82, and a second connecting port 84 is provided on the side wall of the second air supply duct 82 facing the first air supply duct 81. The air mixing inlet 85 is arranged between the first air supply duct 81 and the second air supply duct 82.

[0092] When the indoor unit of the air conditioner is working, the air mixing fan 86 starts to work, and the indoor air is sucked into the housing 80 by the air mixing inlet 85. Then, under the action of the air mixing fan 86, a part of the indoor air enters the first air supply duct through the first connecting port 83, and the indoor air is mixed with the heat exchange air in the first air supply duct before being blown out indoors. Another part of the indoor air enters the second air supply duct through the second connecting port 84, and the indoor air is mixed with the heat exchange air in the second air supply duct before being blown out indoors. Since the wind blown out of the first air supply duct and the second air supply duct is a mixed wind of the heat exchange air and the indoor air, when the indoor unit of the air conditioner is in the cooling mode, the indoor air can neutralize the relatively strong cold wind, so that the wind blown out of the indoor unit of the air conditioner is cool but not cold. When the indoor unit of the air conditioner is in the heating mode, the indoor air can neutralize the relatively strong warm wind, so that the wind blown out of the indoor unit of the air conditioner is warm but not dry, thereby improving the user experience.
