After being driven by a water pump, water is distributed to several two-way valves through several multi-way valves. The opening or closing of the two-way valves indicates whether the room is cooling or heating. There are a large number of two-way valves and the flow channel plate is large in size. Summary of the Invention

[0004] The inventors discovered that because the two-way valve and several multi-way valves are all installed on the same side of the flow channel plate, the size of the flow channel plate becomes large.

[0005] The purpose of this application is to provide a heat pump water heater thermal management device, including a flow channel plate, a first valve, a second valve, and a third valve. The first valve is used to control the opening and closing of the underfloor heating channel, and the second valve is used to control the opening and closing of the cooling channel. The first valve and the third valve are located on different sides of the flow channel plate, and the first valve, the second valve, and the third valve are all connected to the flow channel plate.

The interface of the first valve is connected to the branch flow channel, the interface of the second valve is connected to the branch flow channel, and the interface of the third valve is connected to either the main flow channel or the branch flow channel.

[0006] In this application, by having the first valve and the third valve located on different sides of the flow channel plate, the size of the flow channel plate is reduced by utilizing the space on different sides of the flow channel plate.

[0007] Another objective of this application is to provide a heat pump water heater thermal management device, including a flow channel plate, a first valve, a second valve, a first sub-valve, and a second sub-valve.

The second valve and the first valve are located on different sides of the flow channel plate. The first valve, the second valve, the first sub-valve, and the second sub-valve are all connected to the flow channel plate. The flow channel plate has a main flow channel and branch flow channels. The interface of the first valve and the interface of the second valve are connected to the branch flow channels, and the interface of the first sub-valve and the interface of the second sub-valve are connected to either the branch flow channels or the main flow channels.

[0025] The exemplary embodiments of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0026] Reference Figure 1 , Figure 2 as well as Figure 3 A heat pump water heater thermal management device includes a flow channel plate 1, a first valve 41, a second valve 42 and a third valve 5. The first valve 41 is used to control the on / off of the floor heating channel in the room, and the second valve 42 is used to control the on / off of the cooling channel in the room.

[0027] The first valve 41 and the third valve 5 are located on different sides of the flow channel plate 1. The first valve 41, the second valve 42 and the third valve 5 are all connected to the flow channel plate 1. The flow channel plate 1 has a main flow channel 11 and a branch flow channel 12. The interface of the first valve 41 is connected to the branch flow channel 12, the interface of the second valve 42 is connected to the branch flow channel 12, and the interface of the third valve 42 is connected to either the main flow channel 11 or the branch flow channel 12.

[0028] In some embodiments, the first valve 41 and the second valve 42 are two-way valves, and the third valve 5 is a multi-way valve. The first valve 41 is used to control the opening and closing of the underfloor heating channels in each space, and the second valve 42 is used to control the opening and closing of the refrigeration channels in each space.

[0029] By placing the first valve 41 and the third valve 5 on different sides of the flow channel plate 1, the space utilization on the flow channel plate 1 is improved by utilizing the different sides of the flow channel plate 1, thereby reducing the size of the flow channel plate 1.

[0030] In some implementations, refer to Figure 1 as well as Figure 2 The first valve 41 is a two-way valve, and the second valve 42 is a two-way valve. The flow channel plate 1 has a thickness direction Z. The direction in which at least two first valves 41 and second valves 42 are distributed is defined as a first linear direction X, which is perpendicular to the thickness direction Z. The first valves 41 and second valves 42 are all located on the same side of the flow channel plate 1. Specifically, the third valve 5 includes a first sub-valve 51 and a second sub-valve 52. Further, the first sub-valve 51 is a three-way valve, and the second sub-valve 52 is a three-way valve.

[0031] Furthermore, the interfaces of the first valve 41 and the second valve 42 are both connected to the branch flow channel 12; the interfaces of the first sub-valve 51 and the second sub-valve 52 are both connected to the main flow channel 11 or the branch flow channel 12.

[0032] Since the interfaces of the first valve 41, the second valve 42, the first sub-valve 51, and the second sub-valve 52 are used to communicate with external components, such as the underfloor heating coil 93 or fan coil unit 92 in a heat pump water system, by setting the first valve 41 and the second valve 42 on one side of the flow channel plate 1 and the first sub-valve 51 and the second sub-valve 52 on the other side of the flow channel plate 1, it is easy to distinguish and connect them. For example, the interfaces of the first valve 41 and the second valve 42 on the same side of the flow channel plate 1 are all connected to the inlet of the external component, and the interfaces of the third valve 5 on the other side of the flow channel plate 1 are all connected to the outlet of the external component.

[0033] In some implementations, refer to Figure 3 as well as Figure 4 The flow channel plate 1 includes a first plate 13 and a second plate 14, both of which are made of plastic. The first plate 13 and the second plate 14 are welded together, forming a main flow channel 11 and a branch flow channel 12 between them. A first valve 41 and a second valve 42 are both connected to the first plate 13, and a third valve 5 is connected to the second plate 14. Specifically, the first valve 41 and the second valve 42 are both connected to the first plate 13, and the first sub-valve 51 and the second sub-valve 52 are both connected to the second plate 14.

[0035] In some implementations, refer to Figure 1 The heat pump water heater thermal management device includes a heat exchanger 8, a water pump 81, a filter 82, and an overflow valve 83. The heat exchanger 8, water pump 81, filter 82, and overflow valve 83 are all connected to the flow channel plate 1. Specifically, the heat exchanger 8, water pump 81, filter 82, and overflow valve 83 are all connected to the main flow channel 11. At least a portion of the heat exchanger 8, at least a portion of the water pump 81, at least a portion of the filter 82, the first valve 41, and the second valve 42 are located on the same side of the flow channel plate 1. At least a portion of the third valve 5 and the overflow valve 83 are located on the same side of the flow channel plate 1.

[0036] Furthermore, the heat exchanger 8, water pump 81, and filter 82 are connected to the first plate 13, and the overflow valve 83 is connected to the second plate 14.

A first valve 41 and a second valve 42 are both connected to the flow channel plate 1. Along the thickness direction Z, the first valve 41 and the second valve 42 are located on the same side of the flow channel plate 1. The first connection port 24 communicates with the interface of the first valve 41, and the second connection port 34 communicates with the interface of the second valve 42. Along the thickness direction Z, the first connection port 24 and the second connection port 34 are located on the same side of the flow channel plate 1, and the first connection port 24 and the second connection port 34 are located on the same side of the first valve 41. The flow channel plate 1 has a thickness direction Z. Along the thickness direction Z, the first valve 41 and the third valve 5 are located on opposite sides of the flow channel plate 1. Specifically, the first connection port 24 and the second connection port 34 both face the same side. Specifically, the first plate 13 has a first connection port 24 and a second connection port 34.

[0038] By having the first connection port 24 and the second connection port 34 both located on the same side of the flow channel plate 1, and the first connection port 24 connected to the interface of the first valve 41, and the second connection port 34 connected to the interface of the second valve 42, and the first connection port 24 and the second connection port 34 both facing the same side, it is convenient to connect the first connection port 24 and the second connection port 34 to external components.

[0039] In some implementations, refer to Figure 3 as well as Figure 4 The branch flow channel 12 includes a first branch 121 and a second branch 122. The heat pump water heater thermal management device includes a first mounting part 2 and a first connecting part 21. The first mounting part 2 is connected to the flow channel plate 1, and the first connecting part 21 is connected to the first mounting part 2. The first mounting part 2 has a first hole 22, and the first connecting part 21 has a first connecting channel 23. The first hole 22 communicates with the first branch 121. The first valve 41 is at least partially located in the first hole 22. The first connecting channel 23 communicates with the interface of the first valve 41. The first connecting port 24 communicates with the first connecting channel 23 and is exposed to the outside of the heat pump water heater thermal management device. The extension direction of the first connecting channel 23 is defined as the second straight direction Y. The second straight direction Y, the first straight direction X, and the thickness direction Z are mutually perpendicular.

[0040] In some implementations, refer to Figure 3 as well as Figure 4 The heat pump water heater thermal management device includes a second mounting part 3 and a second connecting part 31. The second mounting part 3 is connected to the flow channel plate 1, and the second connecting part 31 is connected to the second mounting part 3. The second mounting part 3 has a second hole 32, and the second connecting part 31 has a second connecting channel 33. The second hole 32 communicates with the second branch 122. The second valve 42 is at least partially located in the second hole 32. The second connecting channel 33 communicates with the interface of the second valve 42. The second connecting port 34 communicates with the second connecting channel 33. The second connecting port 34 is exposed to the outside of the heat pump water heater thermal management device. The second connecting channel 33 extends along the second straight direction Y. Along the second straight direction Y, the first connecting part 21 and the second connecting part 31 are both located on the same side of the first mounting part 2 and the second mounting part 3.

[0041] Specifically, refer to Figure 3 as well as Figure 4 The flow channel plate 1 has a first surface 131 and a second surface 141. Along the thickness direction Z, the first surface 131 is located on one side of the second surface 141 and is parallel to the second surface 141. A first mounting portion 2 and a second mounting portion 3 protrude from the first surface 131 in a direction away from the interior of the flow channel plate 1. With this arrangement, the first valve member 41 is installed in the first hole 22 and the second valve member 42 is installed in the second hole 32. This improves the connection strength between the flow channel plate 1 and the first valve member 41, and also improves the connection strength between the flow channel plate 1 and the second valve member 42, while reducing the material of the flow channel plate 1. Only the first mounting portion 2 and the second mounting portion 3 protrude from the flow channel plate 1.

[0042] In some implementations, refer to Figure 3as well as Figure 4 The first plate 13 has a first surface 131, the second plate 14 has a second surface 141, the first mounting part 2 is connected to the first plate 13, and the second mounting part 3 is connected to the first plate 13. Specifically, the first plate 13, the first mounting part 2, and the second mounting part 3 are a single piece.

[0043] The first connecting part 21 and the second connecting part 31 are connected to the external component. The first connecting part 21 and the second connecting part 31 are connected to the flow channel plate 1 through the first mounting part 2 and the second mounting part 3. The flow channel plate 1, which is more stable to install than the first valve 41, is connected to the external component, which reduces the occurrence of the first valve 41 being pulled out of the flow channel plate 1 when it is directly connected to the external component, or causing the connection between the first valve 41 and the flow channel plate 1 to become loose. Compared with the flow channel plate 1, the connection between the first valve 41 and the flow channel plate 1 is less stable.

[0044] In some implementations, refer to Figure 1 as well as Figure 3 The third valve 5 includes a first sub-valve 51 and a second sub-valve 52. The distribution direction of at least two first valves 41 and second valves 42 is a first straight direction X. The first sub-valve 51 has at least three interfaces, and the second sub-valve 52 has at least three interfaces. Along the thickness direction Z, the first sub-valve 51 and the second sub-valve 52 are located on the same side of the flow channel plate 1. Along the thickness direction Z, the first sub-valve 51 and the first valve 41 are located on both sides of the flow channel plate 1.

[0045] Furthermore, referring to Figure 1 as well as Figure 5 Along the first straight direction X, the first sub-valve 51 is at least partially located between the first valve 41 and the second valve 42. By positioning the first sub-valve 51 at least partially between the first valve 41 and the second valve 42, fluid can immediately enter the first valve 41 and the second valve 42 after passing through the first sub-valve 51, shortening the distance between the first sub-valve 51 and the first valve 41 and between the first sub-valve 51 and the second valve 42, resulting in a compact structure and further reducing the size of the flow channel plate 1.

[0046] Specifically, refer to Figure 1 as well as Figure 2 Both the first sub-valve 51 and the second sub-valve 52 are connected to the second plate 14. Specifically, the first sub-valve 51 is connected to the second surface 141, and the second sub-valve 52 is connected to the second surface 141.

[0047] In some implementations, refer to Figure 6The plane perpendicular to the thickness direction Z is defined as the first projection plane S. The orthographic projection of the first valve 41 onto the first projection plane S is the first projection S1. The orthographic projection of the third valve 5 onto the first projection plane S is the second projection S2. The first projection S1 and the second projection S2 are distributed along the first straight line direction X. The second projection S1 is at least partially located within the first projection S2.

[0048] Specifically, refer to Figure 6 The first valve 41 and the second valve 42 are projected onto the first projection plane S as the first projection S1, and the first sub-valve 51 is projected onto the first projection plane S as the second projection S2. The first projection S1 and the second projection S2 are distributed along the first straight line direction X.

[0049] In some implementations, refer to Figure 1 as well as Figure 2 The first sub-valve 51 and the second sub-valve 52 are distributed along the second straight direction Y. The second straight direction Y, the first straight direction X, and the thickness direction Z are mutually perpendicular. Along the first straight direction X, the second sub-valve 52 is at least partially located between the first valve 41 and the second valve 42. This is achieved by positioning the second sub-valve 52 at least partially between the first valve 41 and the second valve 42.

[0050] Specifically, refer to Figure 1 as well as Figure 2 Along the second straight line direction Y, the first connection port 24, the second connection port 34, and the second sub-valve 52 are all located on the same side of the first sub-valve 51. This arrangement makes it easy to ensure that the opening directions of the interface of the second sub-valve 52 are consistent with those of the first connection port 24 and the second connection port 34.

[0051] In some implementations, refer to Figure 1 as well as Figure 3 The third valve component 5 includes a first sub-valve component 51 and a second sub-valve component 52.

[0066] In some implementations, refer to Figure 7 as well as Figure 9 At least two first valve members 41 are provided, and the at least two first valve members 41 are distributed along the first direction X1. Along the first direction X1, the at least two first valve members 41 are located on the same side of the second sub-valve member 52.

[0067] Specifically, refer to Figure 7 as well as Figure 9 At least two second valves 42 are provided, and the at least two second valves 42 are distributed along the first direction X1. Along the first direction X1, the at least two second valves 42 are located on the same side of the first sub-valve 51.

[0068] Furthermore, referring to Figure 7 as well as Figure 9The flow channel plate 1 has a thickness direction Z. Along the thickness direction Z, the first valve 41 and the second sub-valve 52 are located on the same side of the flow channel plate 1.
