Description

Technical Field

[0001] This invention relates to the field of valve body technology, specifically to a multi-way valve device. Background Technology

[0002] Currently, mainstream heat pump air conditioners, water heaters and other systems on the market use four-way reversing valves to switch the refrigerant flow path in the system, thereby realizing the cooling, heating and defrosting functions of the entire system.

[0003] Taking air conditioners as an example, the existing four-way valve connects the indoor heat exchanger to the C-connector and the outdoor heat exchanger to the E-connector. When the system is running, the variable frequency compressor and electronic expansion valve match the heat exchanger and environmental conditions to adjust the operating status and achieve rapid temperature (heating).

[0004] The traditional four-way valve has the following shortcomings: the C-connector of the four-way valve is connected to the indoor heat exchanger and the E-connector is connected to the outdoor heat exchanger. The four-way valve only has two switching states: cooling and heating. The operating mode is relatively limited and cannot be adjusted to the optimal operating condition according to a specific environment. Therefore, it is not good in terms of energy saving or comfort.

[0005] This case arose because of the shortcomings of existing four-way valves. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a multi-way valve device that solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-way valve device, comprising a valve body, a D channel, an S channel, a C1 channel, a C2 channel, an E1 channel, and an E2 channel. The D, S, C1, C2, E1, and E2 channels are all connected to the valve body. The D and S channels are inlet and outlet channels connecting the valve body to an external carrier, respectively. A switching assembly is provided within the valve body. The switching assembly includes two through sections, each capable of connecting the D channel to one or both C channels, and the S channel to one or both E channels.

[0008] The valve body includes a housing and upper and lower valve seats at the upper and lower ends of the closed housing.

[0009] The D channel is connected to the side of the housing, the S channel is connected to the bottom center of the lower valve seat, and the C1, C2, E1, and E2 channels are located at the bottom of the lower valve seat and are distributed at an angle around the S channel.

[0010] The C1 and C2 channels, and the E1 and E2 channels are symmetrically arranged on both sides of the S channel, with each of the C1 and C2 channels and the E1 and E2 channels spaced 60° apart.

[0011] The switching component includes a slider and a driver. The slider is rotatably disposed between the upper valve seat and the lower valve seat. The driver is used to drive the slider to rotate. The cross-section of the slider does not completely cover the housing. The missing part is an external notch. A sunken fan-shaped opening is provided on the bottom of the slider opposite to the external notch. The external notch and the fan-shaped opening are two through parts. The fan-shaped opening covers the S channel. The external notch and the fan-shaped opening can simultaneously pass through one or two C channels and E channels.

[0012] The slider has a stop piece on its side that can block the D channel.

[0013] The D channel, S channel, C1 channel, C2 channel, E1 channel, and E2 channel are pipes or flow channels.

[0014] This invention provides a multi-way valve device. It has the following advantages: 1. Compared to a four-way valve, this multi-way valve device increases the number of E and C channels, allowing it to match more outdoor and indoor heat exchangers in air conditioning heat pump systems. It can switch operating conditions according to different working environments to achieve energy-saving effects. Attached Figure Description

[0017] This invention provides a multi-way valve device, such as... Figure 1-11 As shown, it includes a valve body, D channel 3, S channel 4, C1 channel 5, C2 channel 6, E1 channel 7, and E2 channel 8. D channel 3, S channel 4, C1 channel 5, C2 channel 6, E1 channel 7, and E2 channel 8 are all connected to the valve body.

[0018] Channel D3 and channel S4 are inlet and outlet channels connecting the valve body to an external carrier. A switching assembly is installed inside the valve body; the switching assembly includes two through sections, each of which can connect channel D3 to one or both channels C, and channel S4 to one or both channels E.

[0019] Taking an air conditioning heat pump system as an example, channel D3 is used to connect to the compressor exhaust port, and channel S4 is used to connect to the compressor return port. This air conditioner has two outdoor heat exchangers and two indoor heat exchangers. Channels C15 and C26 are connected to the inlets of the two outdoor heat exchangers, respectively, and channels E17 and E28 are connected to the outlets of the two indoor heat exchangers, respectively. The piping between the two outdoor heat exchangers and the two indoor heat exchangers is controlled in parallel via expansion valves.

[0020] The valve body includes a circular housing 1 and upper valve seats 10 and lower valve seats 2 at the upper and lower ends of the closed housing 1. A chamber is formed between the upper valve seats 10 and the lower valve seats 2.

[0021] like Figure 3 As shown, channel D 3 connects to the side of housing 1 and communicates with the internal chamber. Channel S 4 connects to the bottom center of lower valve seat 2 and communicates with the internal chamber. Fan-shaped opening 93 always extends through channel S 4. Channels C1 5, C2 6, E1 7, and E2 8 are located at the bottom of lower valve seat 2 and are distributed at an angle around channel S 4.

[0022] like Figure 4 As shown, channels C1 5 and C2 6, and channels E1 7 and E2 8 are symmetrically arranged on both sides of channel S 4. Channels C1 5 and C2 6 are spaced 60° apart, and channels E1 7 and E2 8 are spaced 60° apart. Channels C1 5 and E2 8 are spaced 120° apart, and channels C2 6 and E1 7 are spaced 120° apart.

[0023] The switching assembly includes a slider 9 and a driver. The slider 9 is rotatably mounted between the upper valve seat 10 and the lower valve seat 2 via a main shaft 12. The lower end of the main shaft 12 is pivotally connected to the S channel 4 via a bushing 13. The driver, a stepper motor 11, drives the slider 9 to rotate. The slider 9 does not completely cover the housing 1; the missing part is an outer notch 92. The cavity between the outer notch 92 and the housing 1 is the outer cavity. A recessed fan-shaped opening 93 is provided on the bottom of the slider 9 opposite to the outer notch 92. The cavity within the fan-shaped opening 93 is the inner cavity. The outer notch 92 and the fan-shaped opening 93 are two through-sections. The fan-shaped opening 93 covers the S channel 4, and the outer notch 92 and the fan-shaped opening 93 can simultaneously penetrate one or two C channels and E channels. Figure 6 As shown, the fan-shaped opening 93 only passes through one E1 channel 7. (As...) Figure 7 As shown, the fan-shaped opening 93 simultaneously connects E1 channel 7 and E2 channel 8.

[0024] The side of the slider 9 is provided with a stop plate 94 that can block the D channel 3. When the slider 9 drives the stop plate 94 to rotate to the position of blocking the D channel 3, the fluid in the D channel 3 cannot enter the chamber.

[0025] Channels D (3), S (4), C1 (5), C2 (6), E1 (7), and E2 (8) are pipes or flow channels. In this embodiment, pipes are used, but it is not limited to integrating the above channels into the carrier in the form of flow channels.

[0026] Working principle: This multi-way valve, when paired with two outdoor heat exchangers and two indoor heat exchangers, offers six operating conditions: Operating condition one, such as Figure 6 As shown, the fluid flow path is: compressor → D channel 3 → C1 channel 5 → outdoor heat exchanger 1 → expansion valve → indoor heat exchanger 1 → E1 channel 7 → S channel 4 → compressor.

[0027] Operating condition two, such as Figure 7 As shown, the fluid flow path is: compressor → D channel 3 → C1 channel 5, C2 channel 6 → outdoor heat exchanger 1, outdoor heat exchanger 2 → expansion valve → indoor heat exchanger 1, indoor heat exchanger 2 → E1 channel 7, E2 channel 8 → S channel 4 → compressor.

[0028] Operating condition three, such as Figure 8 As shown, the fluid flow path is: compressor → D channel 3 → C2 channel 6 → outdoor heat exchanger 2 → expansion valve → indoor heat exchanger 2 → E2 channel 8 → S channel 4 → compressor.

[0029] Operating condition four, such as Figure 9 As shown, the fluid flow path is: compressor → S channel 4 → E2 channel 8 → indoor heat exchanger 2 → expansion valve → outdoor heat exchanger 2 → C2 channel 6 → D channel 3 → compressor.

[0030] Operating condition five, such as Figure 10 As shown, the fluid flow path is: compressor → S channel 4 → E1 channel 7, E2 channel 8 → indoor heat exchanger 1, indoor heat exchanger 2 → expansion valve → outdoor heat exchanger 1, outdoor heat exchanger 2 → C1 channel 5, C2 channel 6 → D channel 3 → compressor.

[0031] Operating condition six, such as Figure 11 As shown, the fluid flow path is: compressor → S channel 4 → E1 channel 7 → indoor heat exchanger 1 → expansion valve → outdoor heat exchanger 1 → C1 channel 5 → D channel 3 → compressor.
