Description

Technical Field

The utility model relates to the technical field of heat supply, in particular to a hydraulic module, an energy supply device and an energy supply system.

Background

At present, when the problem of different requirements of cooling and heating is solved, the heating and cooling functions are generally realized through two sets of relatively independent equipment. Corresponding to the home market, two sets of relatively independent devices for realizing heating and cooling functions are difficult to popularize, and users are generally not favored to purchase relatively independent devices in view of various reasons such as installation and maintenance. Therefore, a heat source unit with a heat supply function and a first heat exchange unit capable of supplying heat or cooling are integrated in the same device, so that the device has two main functions of heating and cooling.

However, since the heat source unit and the first heat exchange unit are integrated in one set of equipment, the internal structure is relatively complex, and complicated connection exists between the heat source unit and the first heat exchange unit, the first heat exchange unit in the equipment of different types has the characteristics of the equipment in terms of structural size and the like, and cannot have universality, so that the cost is not reduced in the production and manufacturing process of the equipment. In addition, the use of the previously existing first heat exchange unit is also disadvantageous in product upgrades. Finally, when the first heat exchange unit in the equipment fails or has a problem, maintenance personnel cannot easily replace or maintain the first heat exchange unit.

Likewise, a three-way connection may be connected to the second position of the first fluid output line 11, and the second connection tube 132 may be detachably connected to the three-way connection. By the above mode, the first connecting pipe 142, the second connecting pipe 142 and the first fluid output pipeline 11 can be conveniently installed and detached, and maintenance and replacement are facilitated. In other possible ways, a four-way connection may be connected to the first fluid output line 11, for example, the four-way connection may be substantially "pi" shaped, and the first connection pipe 142 and the second connection pipe 132 may be detachably connected to the four-way connection.

The hydraulic module 27 may include: a fluid driving unit 21 for driving the fluid in the second flow path 32 to flow.

The hydraulic module 27 may also include a first fluid input line 12 and a first fluid output line 11. The hydraulic module 27 may be detachably connected to the water inlet and outlet lines of the heat source unit 2 through the first and

second connection pipes

142 and 132.

In order to realize that the fluid driving unit 21, the first heat exchanging unit 3, the first connection pipe 142 and the second connection pipe 132 form separate modules, that a fixed connection is realized between each other, etc., as is possible, as shown in fig. 1 and 2, the hydraulic module 27 may comprise: a rear support plate 19, and a top plate 20 attached to the rear support plate 19. The rear support plate 19 may be detachably connected to the rear surface of the housing 1, for example, by screws or the like, to the housing 1. The top plate 20 may be detachably connected to the upper end surface of the housing 1. This makes it possible to support and fix the hydraulic module 27 by the housing 1, and also to detachably connect the hydraulic module 27 from the housing 1 to the housing 1.

As shown in fig. 1 and 2, the first heat exchange unit 3 may be fixedly coupled to the rear support plate 19. The fifth port 25, the sixth port 26, the third port 8 and the fourth port 9 are installed on the top plate 20 so that the corresponding fluid can be inputted or outputted from the upper end surface of the power supply device 100. Because the weight of the fluid driving unit 21 is large, the fluid driving unit 21 needs to be fixed and bear the weight, as a practical way, the inlet of the fluid driving unit 21 can face upwards, the inlet of the fluid driving unit 21 can be fixedly connected to the top plate 20 through the fourth port 9, so that more weight of the fluid driving unit 21 can be directly borne through the top plate 20, and the fluid driving unit 21 and the fourth port 9 can be directly connected with each other to avoid a pipeline with a longer length, so that the stability is improved. The outlet of the fluid driving unit 21 is connected with the first heat exchange unit 3 through the first fluid input pipeline 12 to achieve fixation, and the outlet of the fluid driving unit 21 can face downwards, so that the lower end of the fluid driving unit 21 is fixed to a certain extent, and shaking of the fluid driving unit 21 is prevented. The fluid driving unit 21 is used to drive the flow of the liquid in the second flow channel 32 of the first heat exchanging unit 3, for example, the fluid driving unit 21 may employ a pump or the like.

The hydraulic module 27 may have a height direction, a width direction, and a depth direction. In fig. 2, the vertical direction is the height direction, the left-right direction is the width direction, the direction substantially perpendicular to the paper surface is the depth direction, and in the depth direction, the direction close to the reader is the front, and the direction far from the reader is the rear. As shown in fig. 1 and 2, the fluid driving unit 21 may be located above the first heat exchanging unit 3 in the height direction, and the fluid driving unit 21 is staggered with the first heat exchanging unit 3 in the depth direction. Therefore, in the height direction, there is still room available below the fluid drive unit 21. Further, as shown in fig. 4, the hydraulic module 27 may include: and an electrical control box 22. The electrical control box 22 may be located below the fluid drive unit 21 in the height direction and in front of the first heat exchange unit 3 in the depth direction. By the arrangement, the whole hydraulic module 27 can be more compact and occupies less space.

As a possibility, at least part of the first fluid outlet line 11 may be located on one side of the first heat exchange unit 3 in the width direction, as shown in fig. 2. The first fluid outlet line 11 may be located behind the electrical control box 22 in the depth direction. The first fluid output pipe 11 may extend downward from the third port 8, extend forward after passing through the right side of the first heat exchange unit 3, and then bend into the rear of the electrical control box 22, i.e. the gap between the electrical control box 22 and the first heat exchange unit 3, and finally be connected to the inlet of the second flow channel 32 facing the front at the lower end of the first heat exchange unit 3. In the above manner, the space remaining in the hydraulic module 27 can be fully utilized to arrange the first fluid output pipe 11, so that the entire hydraulic module 27 is more compact.

As a possibility, as shown in fig. 2, at least part of the second connection pipe 132 and at least part of the first connection pipe 142 are located at one side of the first heat exchange unit 3 in the width direction. Since the left space of the right side of the first heat exchange unit 3 is large, the second connection pipe 132 and the first connection pipe 142 may be connected to the second position and the first position of the first fluid output line 11 at the right side of the first heat exchange unit 3, respectively. In the depth direction, at least part of the second connection pipe 132 and at least part of the first connection pipe 142 are located rearward of the electrical control box 22. One end of each of the second connection pipe 132 and the first connection pipe 142 is connected to the first fluid output pipe 11 and then extends downward, and then can be bent to enter the rear of the electric control box 22, that is, a gap between the electric control box 22 and the first heat exchange unit 3, and finally extends downward between the electric control box 22 and the first heat exchange unit 3, and can extend out of the hydraulic module 27 so as to be detachably connected with the fourth connection pipe 131 and the third connection pipe 141, respectively.

Further, as shown in fig. 1 and 2, the fourth port 9 and the third port 8 are located on the same side of the top plate 20 in the width direction, and the direction of the same side is the direction in which the first fluid output line 11 is located on one side of the first heat exchange unit 3. The fifth port 25 and the sixth port 26 are also located on the same side in the opposite direction to the same side of the fourth port 9 and the third port 8. In the thickness direction, the fourth port 9 is located at the front and the third port 8 is located at the rear. When the outlet of the first flow passage 31 of the first heat exchange unit 3 is located at the upper and forward-facing end face, the fifth port 25 is located at the front in the thickness direction, so that the fifth port 25 is connected to the outlet of the first flow passage 31 by piping, and the sixth port 26 is located at the rear. The inlet of the first flow passage 31 of the first heat exchange unit 3 may be located at a lower and forward-facing end surface, and a pipe connecting the inlet of the first flow passage 31 is connected to the sixth port 26 through the right side of the first heat exchange unit 3 and the upper region of the first heat exchange unit 3.

As a possibility, as shown in fig. 1, the top of the electrical control box 22 is provided with a water deflector 221. The water baffle 221 is in an inclined state and is used for guiding the condensed water of the fluid driving unit 21, so that the condensed water formed on the fluid driving unit 21 is prevented from dripping down to the top of the electric control box 22 and flowing into the electric control box 22, and further, the damage to electric equipment in the electric control box 22 is prevented. Further, in the horizontal direction, the lower end of the water baffle 221 extends beyond the side wall of the electrical control box 22, so as to prevent the condensed water flowing out from the lower end of the water baffle 221 from flowing through the side wall of the electrical control box 22 again. The water stop parts protruding upwards can be arranged on two sides of the water baffle 221, so that condensed water on the water baffle 221 cannot flow away from two sides and can only flow to one end of the water baffle 221 with a lower height and then be discharged downwards.

As a possibility, as shown in fig. 1, the hydraulic module 27 may comprise: a water collecting tray 23. The water collecting tray 23 is located below the first heat exchange unit 3 and is used for collecting condensed water generated on the outer wall surface of the first heat exchange unit 3. The water collecting tray 23 may also be used to receive condensed water liquid flowing down from the water baffle 221, and thus, the water collecting tray 23 is also located below the end of the water baffle 221 having a lower height. When the water collecting tray 23 is present, the first connection pipe 142 and the second connection pipe 132 may pass through the water collecting tray 23 while extending downward beyond the hydraulic module 27, so that the arrangement of the first connection pipe 142 and the second connection pipe 132 may be simplified.

In the embodiment of the present application, an energy supply device 100 is further provided, and fig. 5 is a schematic structural diagram of the energy supply device in the embodiment of the present utility model, and as shown in fig. 3 and fig. 5, the energy supply device 100 may include: a housing 1; a heat source unit 2 provided in the housing 1; and any of the hydraulic modules 27 described above. The first heat exchange unit is arranged in the shell. The water inlet pipeline and the water outlet pipeline of the heat source unit can be respectively communicated with the second flow passage. The water inlet pipeline and the water outlet pipeline of the heat source unit are detachably connected with the first connecting pipe and the second connecting pipe respectively.

In the entire energy supply device 100, as shown in fig. 5, the hydraulic module 27 may have a substantially rectangular parallelepiped shape, and the region occupied by the main components of the heat source unit 2 may have a substantially rectangular parallelepiped shape. The heat source unit 2 and the hydraulic module 27 are located on the left and right sides of the upper portion in the housing 1, respectively, in the width direction, and other components such as the piping state control unit 10, the fourth connection pipe 131, and the third connection pipe 141 are located on the lower portion or the lower bottom plate 1001 in the housing 1.

The water collecting tray 23 may have a water collecting chamber. The surface of the water collecting disc 23 forming the water collecting cavity is provided with a heat insulating layer. When the condensed water is collected in the water collecting cavity, the temperature of the outer wall surface of the water collecting disc 23 is relatively not too low due to the existence of the heat insulating layer, so that the possibility that the condensed water is regenerated on the outer wall surface of the water collecting disc 23 is reduced. As shown in fig. 5, when the condensed water is again generated on the outer wall surface of the water collecting tray 23, the condensed water continues to drop onto the lower part of the casing 1, and the lower part of the casing 1 is also electrically powered, which causes a certain risk. In addition, condensed water drops on other parts of the lower portion of the inside of the housing 1 or the outflow of the power supply device 100 from the lower portion of the housing 1 may cause a bad use experience to the user.

As shown in fig. 1 and 2, the water collecting tray 23 may be fixedly coupled to the rear support plate 19 to achieve fixation of the water collecting tray 23. The water collecting tray 23 is positioned below the first heat exchange unit 3 and the electric control box 22. Therefore, the water collecting tray 23 can be fixedly connected with the lower end of the electric control box 22, and most of the weight of the electric control box 22 can be supported and born through the water collecting tray 23, and the electric control box 22 can be fixed. The side of the electric control box 22 facing the first heat exchange unit 3 is fixedly connected with the first heat exchange unit 3 through a fixed connection assembly 24. The upper and/or middle portions of the electrical control box 22 may be further secured by one or more securing connection assemblies 24 to thereby increase the securement of the electrical control box 22. As a possibility, the stationary connection assembly 24 may also be fixed to the first fluid input line 12 between the outlet of the fluid drive unit 21 to the first heat exchange unit 3. For example, one end of the fixed connection assembly 24 is fixedly connected to the first heat exchange unit 3, and the other end of the fixed connection assembly 24 is fixedly connected to the electrical control box 22. The central portion of the fixed connection assembly 24 may clamp the first fluid input line 12 to secure the first fluid input line 12. This is more advantageous for improving the firmness of the first fluid input line 12 for supporting or fixing the fluid drive unit 21 for improving the stability of the fluid drive unit 21.

As shown in fig. 3, the heat source unit 2 may include an inlet and an outlet, and fluid may flow in from the inlet of the heat source unit 2, flow out from the outlet of the heat source unit 2 after being heated by the heat source unit 2. The inlet of the heat source unit 2 and the outlet of the heat source unit 2 can be respectively communicated with the second flow passage 32. Since the water inlet pipeline may include an inlet of the heat source unit 2, may also include an inlet of the heat source unit 2 and a pipeline connected at the outlet, and the water outlet pipeline may include an outlet of the heat source unit 2, may also include an outlet of the heat source unit 2 and a pipeline connected at the outlet, the water inlet pipeline and the water outlet pipeline of the heat source unit 2 are detachably connected with the first heat exchange unit 3.

The heat source unit 2 may be a device capable of heating a fluid. As a practical matter, the heat source unit 2 may include at least one of: gas water heating unit, electric water heating unit, hanging stove unit, etc.

The energy supply device 100 in the embodiment of the present application may have a first working state, where the second flow channel 32 cools the input fluid to form a cold fluid and outputs the cold fluid. The heat source unit 2 may be in a standby or a stop state without supplying heat.

In the first operating condition described above, the third port 8 and the fourth port 9 are used to communicate with the inlet and outlet, respectively, of the heat exchange tubes in the fan coil 300, as shown in fig. 3. At this time, the first flow channel 31 may be fed with a cold fluid, so as to cool the fluid flowing through the second flow channel 32, and the cooled fluid flows out from the third port 8 and is supplied to the heat exchange tube in the fan coil 300, so that the cold fluid exchanges heat with the air flowing outside the heat exchange tube, thereby cooling the air, and also dehumidifying the air. The fluid exiting the heat exchange tubes in the fan coil 300 is recirculated back to the fourth port 9 of the power supply 100 and so on.

The energy supply device 100 in the embodiment of the present application may have a second working state, in which the second flow channel 32 heats the input fluid to form a hot fluid and outputs the hot fluid; at least part of the hot fluid in the second flow path 32 flows into the heat source unit 2 through the inlet of the heat source unit 2, is further heated by the heat source unit 2, and is output back to the second flow path 32 through the outlet of the heat source unit 2.

In the second operating condition described above, the third port 8 and the fourth port 9 may be used for communication with the heat exchange ends, respectively, as shown in fig. 3. The fluid in the heat exchange end enters the second flow channel 32 through the fourth port 9 to exchange heat and raise temperature, at least part of the fluid entering the second flow channel 32 can flow into the heat source unit 2 through the inlet of the heat source unit 2, the fluid is further heated by the heat source unit 2 and then is output into the second flow channel 32 through the outlet of the heat source unit 2, and finally the hot fluid is output and supplied to the heat exchange end through the third port 8. Through the above-described process, the fluid input into the fourth port 9 can be heated simultaneously by the second flow passage 32 of the first heat exchange unit 3 and the heat source unit 2, so that the degree of heating of the fluid and the temperature after heating can be further increased. Particularly, when the first heat exchange unit 3 is a heat exchange component in the heat pump device 400, the heat source unit 2 is a gas hot water unit, an electric hot water unit, a wall-hanging stove unit, or the like, the above manner can increase the temperature of the hot fluid output from the third port 8 of the energy supply device 100 in low-temperature weather, and can also achieve the effect of improving energy efficiency.

The second position of the first fluid output pipe 11 is located upstream of the first position, so that it is ensured that in the second operating state, at least part of the heated fluid output by the second fluid passage 32 after being heated can flow into the heat source unit 2 from the first position, be further heated by the heat source unit 2, be output through the outlet of the heat source unit 2, and flow into the second position of the first fluid output pipe 11 through the second position. Further, the first location may be located adjacent to the second location, thereby allowing for a smaller differential pressure at both locations.

As a possibility, as shown in fig. 3, the power supply device 100 may include: and a pipeline state control unit 10 for controlling the on-off of the inlet of the heat source unit 2 and the second flow channel 32 and/or the on-off of the outlet of the heat source unit 2 and the second flow channel 32. In the first operation state, the pipeline state control unit 10 needs to control the disconnection of the inlet of the heat source unit 2 from at least one of the second flow passage 32 and the outlet of the heat source unit 2 from the second flow passage 32, so that it is possible to make the fluid in the second flow passage 32 not flow into the heat source unit 2. In the second operating state, the pipeline state control unit 10 needs to control the inlet of the heat source unit 2 to communicate with the second flow passage 32, and the outlet of the heat source unit 2 to communicate with the second flow passage 32, so that the fluid in the second flow passage 32 can flow into the inlet of the heat source unit 2, and the fluid flowing out of the outlet of the heat source unit 2 can flow back into the second flow passage 32.

In order to allow a detachable connection between the inlet and outlet of the heat source unit 2 and the first heat exchange unit 3, in one possible embodiment, the energy supply device 100 may include: a third connection pipe 141, the third connection pipe 141 being connectable to a water inlet pipe at an inlet of the heat source unit 2, the first connection pipe 142 being detachably connected to the third connection pipe 141; the fourth connection pipe 131, the fourth connection pipe 131 can be connected with an outlet pipe at the outlet of the heat source unit 2, and the second connection pipe 132 and the fourth connection pipe 131 are detachably connected. With the above structure, the first heat exchange unit 3 can be detachable from the heat source unit 2 to be replaceable, whereby the first heat exchange unit 3 can be adapted as a standard module to, for example, different heat source units 2, and in addition, the maintenance of the first heat exchange unit 3 can be facilitated. In some embodiments, the first heat exchange unit 3 may be a heat exchange component in the heat pump device 400, where the first heat exchange unit may have a refrigerant leakage or the like that needs to be overhauled, and by taking the first heat exchange unit 3 as an independent detachable module, the first heat exchange unit 3 may be quickly and conveniently detached from the housing 1 of the energy supply device 100 for maintenance or inspection, and may be conveniently reinstalled in the housing 1 of the energy supply device 100 at a later stage, so that the maintenance speed may be improved and the difficulty of maintenance may be reduced.

Further, as shown in fig. 3 and 5, the third connection pipe 141 and the first connection pipe 142 may be detachably connected by plugging. The fourth connecting pipe 131 and the second connecting pipe 132 are detachably connected in a plugging manner. Because the other ends of the third connecting pipe 141 and the first connecting pipe 142 are connected, the other ends of the fourth connecting pipe 131 and the second connecting pipe 132 are connected, and the connecting pipes cannot rotate, compared with other detachable modes, the plugging mode can avoid rotating during connection, so that the first heat exchange unit 3 is more convenient to detach from or install in the shell 1 of the energy supply device 100, the time is saved, and the operation of maintenance personnel is facilitated.

In one possible embodiment, the connection pipes can be plugged together by the following structure. Fig. 6 is a schematic diagram of a plug-in position of an inner pipe and an outer pipe in an embodiment of the present utility model, as shown in fig. 6, one of the third connecting pipe 141 and the first connecting pipe 142 is the inner pipe 15, and the other is the outer pipe 16. And/or one of the fourth connection pipe 131 and the second connection pipe 132 is the inner pipe 15 and the other is the outer pipe 16. When the inner tube 15 is inserted into the outer tube 16, a clip 17 capable of keeping the inner tube 15 inserted into the outer tube 16 is installed outside the inner tube 15 and the outer tube 16. The inner tube 15 and the outer tube 16 are effectively prevented from being separated by the clamping member 17. Further, fig. 7 is a cross-sectional view of the junction of the inner tube and the outer tube in fig. 6, wherein the inner wall of the outer tube 16 has a first blocking portion 161 and the outer wall of the outer tube 16 has a second blocking portion 162 as shown in fig. 7. The outer wall of the inner tube 15 has a third blocking portion 151. The inner tube 15 can be inserted into the outer tube 16, and the first blocking portion 161 can limit the end portion of the inner tube 15 or the third blocking portion 151. The distance of insertion of the inner tube 15 into the outer tube 16 is controlled by this structure. The holder 17 has an upper blocking portion 171 and a lower blocking portion 172, the upper blocking portion 171 being capable of abutting against the third blocking portion 151, and the lower blocking portion 172 being capable of abutting against the second blocking portion 162. When the clamping member 17 is sleeved on the inner tube 15 and the outer tube 16, the inner tube 15 cannot be pulled out of the outer tube 16 through the structure.

In order to ensure the tightness between the inner tube 15 and the outer tube 16, as shown in fig. 7, as a possibility, the outer wall of the inner tube 15 has a fourth blocking portion 152, and a seal ring 18 is provided between the outer wall of the inner tube 15 and the inner wall of the outer tube 16, the seal ring 18 being located between the third blocking portion 151 and the fourth blocking portion 152.

As shown in fig. 1 and 5, the first fluid output line 11 may be provided inside the housing 1. When the fourth port 9 communicates with the inlet of the second flow channel 32 via the fluid drive unit 21, the first fluid input line 12, the fluid drive unit 21 and the first fluid input line 12 may also be arranged inside the housing 1. The hydraulic module 27 may be detachably connected to the housing 1. When the first heat exchange unit 3 requires maintenance, the hydraulic module 27 can be detached directly from the housing 1 of the power supply device 100.

As a possible embodiment, fig. 4 is a system diagram of a cold and hot energy supply system including an energy supply device according to an embodiment of the present utility model in another implementation, and as shown in fig. 4, the energy supply device 100 may include a first port 4 and a second port 5, where the first port 4 and the second port 5 are used to communicate with a heat exchange end. The heat exchange end may be different from or the same as the heat exchange end of the second flow path 32 for supplying cold and/or heat, and is not limited in this application.

As shown in fig. 4, the first port 4 can communicate with an inlet of the heat source unit 2, and the second port 5 can communicate with an outlet of the heat source unit 2. The fluid may flow in from the first port 4, then into the inlet of the heat source unit 2, after being heated by the heat source unit 2, then out through the outlet of the heat source unit 2, and finally out from the second port 5.

The energy supply device 100 in the embodiment of the present application may have a third working state, where the second flow channel 32 cools the input fluid to form a cold fluid and outputs the cold fluid. The heat source unit 2 receives the fluid input from the first port 4, heats the fluid to form a hot fluid, and outputs the hot fluid to the second port 5.

In the third operating condition described above, the first port 4 and the second port 5 are used to communicate with the inlet and outlet, respectively, of the first heat exchange tube 3001 in the fan coil 300, as shown in fig. 4. The power supply apparatus 100 may include: a third port 8 in communication with an outlet of the second flow path 32; and a fourth port 9 communicating with the inlet of the second flow passage 32. The third port 8 and the fourth port 9 are for communication with the inlet and outlet, respectively, of the second heat exchange tube 3002 in the fan coil 300. At this time, the first flow channel 31 may be fed with a cold fluid, so that the fluid flowing through the second flow channel 32 may be cooled, the cooled fluid flows out from the third port 8 and is supplied to the second heat exchange tube 3002 in the fan coil 300, and the cold fluid exchanges heat with air flowing through the outside of the second heat exchange tube 3002, so that the air may be cooled, and the air may also be dehumidified. At the same time, the fluid in the first heat exchange tube 3001 in the fan coil 300 flows into the first port 4, is heated by the heat source unit 2 to form a hot fluid, and then flows back into the first heat exchange tube 3001 through the second port 5. The hot fluid exchanges heat with air flowing outside the first heat exchange tube 3001 so that the air can be warmed up. When the air is dehumidified by the second heat exchange tube 3002, the temperature thereof is reduced, and then the air can be warmed up by the first heat exchange tube 3001, so that the air is dehumidified by the fan coil 300, but the temperature thereof is not significantly reduced or is substantially the same as before entering the fan coil 300. The dehumidified air output through the process can meet the requirements that a user dehumidifies and needs to keep the temperature from being reduced too much, and the comfort of the user can be effectively improved.

When the first port 4 and the second port 5 of the energy supply device 100 are not connected to other, e.g. not in communication with the inlet and the outlet of the first heat exchange tube 3001 in the fan coil 300, nor the energy supply device 100 is in the first operating state, the heat source unit 2 further comprises a first blocking member capable of blocking the first port 4 and a second blocking member capable of blocking the second port 5. In this way it is ensured that in the second operating state of the power supply device 100 fluid flowing through the second fluid outlet line 13, the second fluid inlet line 14 does not leak from the first port 4 and the second port 5. To facilitate plugging or unsealing the first port 4 and the second port 5, the first port 4 and the second port 5 may be located outside the housing 1 or on the housing 1.

In one possible embodiment, as shown in fig. 4 and 5, the energy supply device 100 may include: and a second three-way joint 6. The first connection port of the second three-way joint 6 forms a second port 5, the second connection port of the second three-way joint 6 is connected to the water outlet line of the heat source unit 2, and the third connection port of the second three-way joint 6 can be communicated with the second position of the first fluid outlet line 11. For example, the third connection port of the second three-way joint 6 can communicate with the second position of the first fluid output line 11 via the second fluid output line 13. The line state control unit 10 may include a first opening and closing valve 101 connected to the second fluid output line 13. Further, fig. 10 is an enlarged schematic diagram of the first on-off valve in fig. 5, as shown in fig. 10, the second fluid output pipeline 13 and the first on-off valve 101 are detachably connected in a plugging manner, so that the first on-off valve 101 can be conveniently and quickly mounted on the second fluid output pipeline 13, two ends of the second fluid output pipeline 13 are connected with other components, and thus the first on-off valve 101 can be mounted without rotating, time is saved, and later maintenance and replacement are facilitated.

In one possible embodiment, as shown in fig. 4 and 5, the energy supply device 100 may include: a first three-way joint 7. The first connection port of the first three-way joint 7 forms the first port 4, the second connection port of the first three-way joint 7 is connected with the water intake pipe of the heat source unit 2, and the third connection port of the first three-way joint 7 can be communicated with the first position of the first fluid output pipe 11. For example, the third connection port of the first three-way joint 7 can be in communication with the first position of the first fluid output line 11 via the second fluid input line 14. The line state control unit 10 includes a second on-off valve connected to the second fluid input line 14. Further, the second fluid output pipe 13 is detachably connected with the second opening/closing valve by plugging. Similarly, the two ends of the second fluid output pipe 13 are connected with other parts, so that the second on-off valve can be installed without rotation, time is saved, and later maintenance and replacement are facilitated. A flow rate detection device 28 may be connected to the first fluid output line 11 to detect the flow rate of the fluid output from the first heat exchange unit 3. The flow sensing device 28 may be located upstream of the first location.

In the above embodiment, the third connecting pipe 141 is connected to the third connecting port of the first three-way joint 7. A first connecting pipe 142 is connected to the first position of the first fluid output line 11. The second fluid input line 14 includes a third connection pipe 141 and a first connection pipe 142. A fourth connection pipe 131 is connected to the third connection port of the second three-way joint 6. A second connection pipe 132 is connected to the second position of the first fluid output pipe 11. The second fluid output line 13 includes a fourth connection pipe 131 and a second connection pipe 132.

In other possible embodiments, as shown in fig. 4 and 5, the pipeline state control unit 10 may be configured to control the on-off state between the third connection port of the first three-way joint 7 and the first position of the first fluid output pipeline 11 and/or the on-off state between the third connection port of the second three-way joint 6 and the second position of the first fluid output pipeline 11.

Specifically, the pipeline state control unit 10 may include: a first on-off valve 101 connected between the third connection port of the second three-way joint 6 and the first fluid output pipe 11. In the first operating state, the first opening/closing valve 101 may be in a closed state, and the second flow passage 32 cools the input fluid to form a cold fluid and outputs the cold fluid; the heat source unit 2 receives the fluid input from the first port 4, heats the fluid to form a hot fluid, and outputs the hot fluid to the second port 5.

As a possibility, as shown in fig. 4, the pipeline state control unit 10 may include: the unidirectional flow guiding mechanism 102 is connected between the third connecting port of the first three-way joint 7 and the first position of the first fluid output pipeline 11, and the unidirectional flow guiding mechanism 102 can be conducted from the first position to the third connecting port of the second three-way joint 6 under preset pressure; or, a second on-off valve connected between the third connection port of the first three-way joint 7 and the first position of the first fluid output pipe 11. In the first operating state, the second opening/closing valve may be in a closed state. The unidirectional diversion mechanism 102 or the second on-off valve may be provided such that the first operation state of the energy supply device 100, in which cold fluid of the second flow passage 32 of the first heat exchange unit 3 cannot enter the heat source unit 2, can still be made to operate normally when the first on-off valve 101 fails. It should be noted that, the unidirectional diversion mechanism 102 needs to be capable of opening communication under a certain fluid pressure, so that in the first working state, the unidirectional diversion mechanism 102 cannot be opened by a smaller pressure at both ends. Next, the unidirectional flow guide mechanism 102 or the second on-off valve may be provided to detect the heat source unit 2 by using the liquid when the energy supply device 100 is checked for air tightness, so that the liquid is prevented from entering the first heat exchange unit 3. This is because the liquid is difficult to drain once it has entered the first heat exchange unit 3 and may flow out during transport of the later energy supply device 100, resulting in wetting of the package.

Further, as shown in fig. 5, when the pipeline state control unit 10 includes the unidirectional flow guiding mechanism 102, the unidirectional flow guiding mechanism 102 may be disposed in the third connection port of the first three-way joint 7. In this way, the space occupied by the components of the power supply device 100 can be reduced. In addition, when the third connection port of the first three-way joint 7 can be communicated with the first position of the first fluid output pipeline 11 through the second fluid input pipeline 14, the second fluid input pipeline 14 is only required to be connected with the third connection port of the first three-way joint 7 once, so that the connection of the unidirectional flow guiding mechanism 102 in the second fluid input pipeline 14 is avoided, and the connection step is also required twice. Therefore, the above-mentioned method can reduce the installation steps in the production of the energy supply device 100, and also can make the maintenance of the energy supply device 100 more convenient and faster. Further, as shown in fig. 8, the second fluid input pipeline 14 can be detachably connected with the third connecting port of the first three-way joint 7 in a plugging manner, so that the installation between the second fluid input pipeline 14 and the first three-way joint 7 can be completed without rotating, time is saved, and later maintenance and replacement are facilitated. Similarly, as shown in fig. 9, the second fluid output pipeline 13 may be detachably connected with the third connection port of the second three-way joint 6 in a plugging manner.

When the pipeline and the three-way joint are detachably connected in an inserting mode, after the pipeline is inserted into the connecting port of the three-way joint, a groove body is formed in the side wall of the connecting port of the three-way joint, a limiting piece can be installed in the groove body, the limiting piece can be a clamp with a limiting effect, and the pipeline inserted into the connecting port of the three-way joint is limited through the limiting piece so as to prevent the pipeline from being separated from the connecting port of the three-way joint.

As a possible configuration, fig. 10 is an enlarged schematic view of the first opening/closing valve in fig. 5, and as shown in fig. 10, the second fluid output pipe 13 and the first opening/closing valve 101 may be configured to be inserted between the inner pipe 15 and the outer pipe 16. Both ends of the first opening/closing valve 101 correspond to the outer pipe 16, and the second fluid output pipe 13 corresponds to the inner pipe 15. After the two ends of the first on-off valve 101 are spliced with the second fluid output pipeline 13, the two ends of the first on-off valve 101 can be similarly limited by adopting the sleeved clamping piece 17, so that the first on-off valve 101 and the second fluid output pipeline 13 are effectively prevented from being separated.

As a possible embodiment, fig. 11 is a schematic structural view of the condensate water draining device in the first embodiment of the present utility model, fig. 12 is a schematic structural view of the condensate water draining device in the second embodiment of the present utility model, and fig. 13 is a schematic structural view of the condensate water draining device in the third embodiment of the present utility model, as shown in fig. 3, 11 to 13, the energy supply device 100 may include: the condensed water drain device 200. The condensed water drain device 200 collects condensed water in the water collecting tray 23 and condensed water generated by the heat source unit 2, and then discharges the condensed water together with the energy supply device 100. The condensed water drain device 200 may have first and

second ports

2001 and 2002, drain ports 2003, and the heat source unit 2 and the water collecting tray 23 are connected to the first and

second ports

2001 and 2002, respectively, through pipes so that the generated condensed water can be input to the first and

second ports

2001 and 2002, respectively, and drained from the drain ports 2003. The number of drain ports 2003 in the power supply apparatus 100 can be reduced by the condensed water drain apparatus 200 so that only one drain pipe is required to be connected to the drain ports 2003 in the entire power supply apparatus 100 at a later stage.

In the above embodiment, the heat source unit 2 may be a device that generates condensed water, and for example, the heat source unit 2 may include a wall-mounted boiler unit, a gas water heater unit. The wall-mounted furnace unit or the gas hot water unit comprises a condensing heat exchanger; a shell 201 surrounding at least part of the condensing heat exchanger. The gas of the wall-hanging stove unit or the gas hot water unit can generate water vapor after being combusted in the cover body 201, and condensed water can be formed on the cover body 201 after being cooled. Therefore, the condensed water generated in the cover 201 needs to be discharged. The first port 2001 of the condensate drain device 200 may be connected to the housing 201 by a conduit to receive condensate within the housing 201.

As a possibility, as shown in fig. 11 to 13, the condensed water drain device 200 may include: a water seal assembly 2004 having a water seal function. The water seal assembly 2004 can prevent the fume inside the housing 201 from leaking out through the drain port 2003 of the condensed water drain device 200. The water seal assembly 2004 has a first port 2001, and the first port 2001 is used for collecting condensed water of the heat source unit 2 through a pipe. For example, when the heat source unit 2 may include a wall-hanging stove unit or a gas hot water unit, the cover 201 is connected to the first interface 2001 through a pipe.

In one possible embodiment, as shown in fig. 11, the water seal assembly 2004 may have a second port 2002, the second port 2002 being connected to the water collection tray 23 by a pipe. In this embodiment, the outlet of the water seal assembly 2004 may be a drain port 2003. The water seal module 2004 functions to collect and collect the condensed water in the water collecting tray 23 and the condensed water generated from the heat source unit 2, as well as the water seal function. Further, the housing 1 may include a lower plate 1001, and the water seal assembly 2004 is disposed above the lower plate 1001, for example, fixedly disposed on an upper end surface of the lower plate 1001, so that an outlet of the water seal assembly 2004 passes through the lower plate 1001 from top to bottom, thereby facilitating the connection of the drain pipe to the drain port 2003 outside the lower plate 1001 of the power supply apparatus 100 after the installation of the power supply apparatus 100 is completed.

In another possible embodiment, as shown in fig. 12, the condensed water drain device 200 may include: three-way structure 2005. The first orifice of the three-way structure 2005 is connected to the outlet of the water seal assembly 2004, the second orifice of the three-way structure 2005 forms the second interface 2002, and the third orifice of the three-way structure 2005 forms the drain port 2003. Condensed water generated by the heat source unit 2 is discharged into a first pipe orifice of the three-way structural member 2005 after passing through the water seal assembly 2004, the condensed water in the water collecting tray 23 is discharged into a second pipe orifice of the three-way structural member 2005, the condensed water is summarized through the three-way structural member 2005, and finally the condensed water is discharged through a third pipe orifice of the three-way structural member 2005.

Further, in this embodiment, as shown in fig. 12, the water seal assembly 2004 may be located above the lower plate 1001, for example, fixedly disposed on an upper end surface of the lower plate 1001, so that an outlet of the water seal assembly 2004 passes through the lower plate 1001 from top to bottom. The first orifice of the three-way structure 2005 is connected to the outlet of the water seal assembly 2004 below the lower base plate 1001. The second pipe orifice of the three-way structure 2005 passes through the lower plate 1001 from bottom to top, and the pipe connected to the water collecting tray 23 is connected to the second pipe orifice of the three-way structure 2005 above the lower plate 1001. Through the structure, the pipeline connected with the water collecting disc 23 does not need to pass through the lower base plate 1001 downwards, so that the three-way structural member 2005 can be connected with the pipeline connected with the water collecting disc 23 and the outlet of the water seal assembly 2004 quickly and conveniently, the installation time is saved, and meanwhile, the lower base plate 1001 can play a clamping and fixing role on the second pipe orifice of the three-way structural member 2005, so that the three-way structural member 2005 cannot fall off easily.

In order to facilitate the connection of the first orifice of the three-way structure 2005 with the outlet of the water seal assembly 2004, the connection of the second orifice of the three-way structure 2005 with the pipe connected with the water collection tray 23, the first orifice of the three-way structure 2005 may be connected with the outlet of the water seal assembly 2004 by plugging, and the pipe connected with the water collection tray 23 may also be connected with the second orifice of the three-way structure 2005 by plugging. In order to achieve the above objective, when the first pipe orifice of the three-way structure 2005 moves upwards and is plugged with the outlet of the water seal assembly 2004, the second pipe orifice of the three-way structure 2005 can pass through the lower bottom plate 1001 upwards at the same time, the first pipe orifice of the three-way structure 2005 needs to be arranged upwards, and the second pipe orifice of the three-way structure 2005 needs to be arranged upwards.

In another possible way when the condensate drain device 200 includes a three-way structure 2005, as shown in fig. 12, the condensate drain device 200 may include: a connection joint 2006 provided on the lower plate 1001. The connection joint 2006 is provided to penetrate and can be fixed to the lower plate 1001. The two ends of the connecting joint 2006 are respectively used for connecting the three-way structural part 2005 and a pipeline connected with the water collecting disc 23. Specifically, the first orifice of the connection joint 2006 is higher than the upper end surface of the lower plate 1001, and the second orifice of the connection joint 2006 is lower than the lower end surface of the lower plate 1001, and the first orifice of the connection joint 2006 forms the second interface 2002. By the above structure, the pipe connected to the water collecting tray 23 can be directly connected to the first pipe orifice of the connection joint 2006 in the housing 1, for example, inserted into the first pipe orifice of the connection joint 2006. The first orifice of the three-way structure 2005 is connected with the outlet of the water seal assembly 2004, the second orifice of the three-way structure 2005 is connected with the second orifice of the connecting joint 2006, and the third orifice of the three-way structure 2005 forms the drain port 2003. Also, in the above embodiment, the water seal assembly 2004 is located above the lower plate 1001, and the outlet of the water seal assembly 2004 is formed to pass through the lower plate 1001 from the top down; three-way structure 2005 is located below lower plate 1001. The first orifice of the three-way structure 2005 is connected to the outlet of the water seal assembly 2004 by way of plugging. The second pipe orifice of the three-way structure 2005 is connected with the second pipe orifice of the connecting joint 2006 in a plugging manner. In this way, the three-way structure 2005 can be directly, conveniently and quickly connected to the outlet of the water seal assembly 2004, the second orifice of the connection joint 2006, directly outside the housing 1.

As a practical matter, as shown in fig. 12 and 13, a liquid level detecting member 20041 for detecting the liquid level of the liquid accumulated in the water seal assembly 2004 is provided in the water seal assembly 2004. When the outlet of the water seal assembly 2004 and the downstream thereof are blocked, the water in the water seal assembly 2004 cannot be smoothly discharged, and the liquid level detecting member 20041 can timely detect that the accumulated water in the water seal assembly 2004 exceeds the preset liquid level, and at this time, the energy supply device 100 can send out a prompt signal to inform the user to clean the outlet of the water seal assembly 2004 and the downstream thereof, so as to ensure smooth liquid discharge.

When the condensed water discharged from the heat source unit cannot be discharged through the drain port 2003, the liquid level detecting member 20041 can detect the occurrence of this and allow the energy supply device to issue a prompt signal. When the condensed water discharged from the water collecting tray 23 cannot be discharged through the drain port 2003, the liquid level detecting member 20041 can detect the occurrence of this and allow the energy supply device to send a prompt signal. Therefore, by means of the liquid level detecting piece 20041, whether the condensed water discharged by the heat source unit and the water collecting tray can be smoothly discharged out of the energy supply device or not can be detected at the same time, the using amount of the liquid level detecting piece 20041 is reduced, and the manufacturing cost of the energy supply device is saved.

In one embodiment, as shown in fig. 12 and 13, the water seal assembly 2004 has a first water storage flow path 20042 and an overflow flow path 20043 therein. The first water storage flow passage 20042 and the overflow flow passage 20043 extend in a substantially vertical direction. The lower end of the overflow flow passage 20043 is communicated with the drain port 2003, and the upper end of the overflow flow passage 20043 is communicated with the upper end of the first water storage flow passage 20042 through the communication cavity 20047. The lower end of the first water storage flow passage 20042 can communicate with the first inlet of the water seal assembly 2004. The first water storage flow passage 20042 stores water, thereby playing the role of water seal. When the water in the first water storage flow passage 20042 exceeds the lowest position of the communication cavity 20047, the water can flow into the overflow flow passage 20043 and be discharged. The liquid level detecting member 20041 may be disposed in the communication chamber 20047, for example, at a position at or above the middle of the communication chamber 20047. Because the flow rate of the condensed water flowing into the water seal assembly 2004 is generally small, the water in the first water storage flow passage 20042 does not reach the position of the liquid level detecting member 20041 when flowing to the overflow flow passage 20043 through the communicating chamber 20047.

When the water seal assembly 2004 has the second port 2002, the second port 2002 may be located on the overflow path 20043 as shown in fig. 11, as is possible when the second port 2002 is connected to the water collecting tray 23 by a pipe.

When the power supply device 100 is started to be used immediately after being installed, the water seal assembly 2004 does not have water therein and cannot function as a water seal, so further, as shown in fig. 12 and 13, the water seal assembly 2004 has the second water storage flow passage 20044 therein. The second water storage flow path 20044 has a tendency to extend in a vertical direction, and an upper end of the second water storage flow path 20044 communicates with the first inlet of the water seal assembly 2004. A floating member 20045 capable of moving in the vertical direction and a floating seat 20046 having a connection passage 200461 are provided in the second water storage flow passage 20044, and when the floating member 20045 blocks one end of the connection passage 200461, the second water storage flow passage 20044 is disconnected from the first water storage flow passage 20042; when the float 20045 is separated from one end of the connection passage 200461, the second water storage flow passage 20044 communicates with the first water storage flow passage 20042 through the connection passage 200461. When there is no water in the second water storage flow passage 20044, the floating member 20045 cannot float, and at this time, the floating member 20045 blocks the connection passage 200461. The function of the water seal can be realized through the structure at the moment. When the condensed water continuously flows into the water seal assembly 2004, after the condensed water in the second water storage flow passage 20044 reaches a certain degree, the floating piece 20045 floats, the second water storage flow passage 20044 is communicated with the first water storage flow passage 20042 through the connecting passage 200461, and at the moment, the function of water seal is realized through the condensed water.
