[0036] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] The disclosure below provides many different embodiments or examples for implementing different structures of the embodiments of the present application. In order to simplify the disclosure of the embodiments of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the embodiments of the present application. In addition, the embodiments of the present application may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0038] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations.

[0039] In order to solve the problems in the prior art, the present application provides a pipe arrangement and a heating and cooling unit. The pipe arrangement can allow heat to flow from bottom to top during heating, thereby reducing the temperature difference at different heights in the indoor environment.

[0040] Figure 1 A schematic structural diagram of a pipe arrangement device provided in an embodiment of the present application is shown; Figure 2 A schematic diagram showing the structure of a pipe arrangement device provided in an embodiment of the present application when a cooling and heating unit operates in cooling mode; Figure 3 A schematic diagram showing the structure of a pipe arrangement device provided by an embodiment of the present application when the cooling and heating unit operates in heating mode; Figure 4 A schematic structural diagram of a docking base and a floor heating system provided in an embodiment of the present application is shown; Figure 5 A schematic structural diagram of a pipe arrangement device and a floor heating system provided in an embodiment of the present application is shown.

[0041] like Figure 1-5 As shown, an embodiment of the present application provides a pipe drain device, which is applied to a cooling and heating unit. The cooling and heating unit includes an indoor unit and an outdoor unit. The pipe drain device includes: an air supply component 1 and a telescopic drain pipe 2.

[0042] The input end of the air supply component 1 is connected to the air outlet end of the indoor unit.

[0043] One end of the telescopic row pipe 2 is connected to the output end of the air supply component 1. The telescopic row pipe 2 is provided with multiple first air outlets 21 at intervals along the first direction X. A fan blade assembly 22 is provided at the first air outlet 21. The fan blade assembly 22 is used to adjust the opening of the first air outlet 21 and the air outlet direction at the first air outlet 21.

[0044] The telescopic tube 2 can be extended and retracted along a first direction X to adjust the height of the first air outlet 21. Specifically, the first direction X is a vertical direction, and the height of the first air outlet 21 is adjusted by extending and retracting the telescopic tube 2. Optionally, the first direction X can be arranged at an acute angle to the vertical direction, so that the height of the first air outlet 21 can be changed when the telescopic tube 2 is extended and retracted along the first direction X.

[0045] In the present application, the height of the first air outlet 21 is adjusted by extending and retracting the telescopic exhaust pipe 2, and the air outlet direction at the first air outlet 21 is adjusted by the fan blade assembly 22. When cooling, the height of the first air outlet 21 can be raised, and the first air outlet 21 can be made to discharge air downward, so that the cold air can settle from top to bottom in the room. When heating, the height of the first air outlet 21 can be lowered, and the air outlet direction of the first air outlet 21 can be adjusted, so that the hot air flows from bottom to top in the room, thereby reducing the temperature difference at different heights of the indoor environment.

[0046] In the related art, the existing cooling and heating units are all combined with indoor and outdoor units. The installation positions of the indoor and outdoor units are fixed, and the air supply method generally adopts central air supply or side air outlet on one side of the wall. When operating in cooling mode in summer, the fan cools and discharges cold air from top to bottom. The density of cold air is large, the cooling rate is fast, and the power consumption is stable. However, when hot air needs to be discharged in winter, the upper or side air outlet methods will cause the hot air to gather above the room due to the low density of hot air, and the cooling rate is low, resulting in great heat loss. At the same time, the air outlet method is fixed, and the hot air close to the fan side will blow directly on the human body, causing great discomfort, and the single-point air supply causes a huge temperature difference in the entire environment, resulting in uneven heat in the space.

[0047] In the embodiment of the present application, the height of the first air outlet 21 can be adjusted by extending and retracting the telescopic exhaust pipe 2, and the first air outlet 21 is arranged at intervals along the extension direction of the telescopic exhaust pipe 2, so that air is supplied to multiple points in the vertical space of the room, thereby making the temperature of the indoor environment uniform.

[0048] Specifically, the fan assembly 22 can control the opening and air supply direction of the first air outlet 21. The fan assembly 22 includes a fan blade movably disposed at the first air outlet 21 and a drive mechanism that drives the fan blade to swing. The drive mechanism drives the fan blade to swing, adjusting the opening and air supply direction of the first air outlet 21, thereby adjusting not only the air volume but also the air supply direction. A single drive mechanism can be used to drive all fan blades for synchronous adjustment, saving the installation of drive mechanisms. Alternatively, a single drive mechanism can control the swinging of one or more fan blades, thereby achieving precise air supply. For example, when the cooling and heating unit is operating in heating mode, the telescopic pipe 2 is extended and retracted, and the drive mechanism controls the fan blade located at the top to close the upper first air outlet 21, while the drive mechanism controls the fan blade located at the bottom to open the lower first air outlet 21 to a certain angle, thereby supplying air to a specific height. This can avoid the discomfort caused by hot air directly blowing on the human body. Moreover, since the hot air flows from the bottom to the top in the room, and the human activity area is also located in the lower area of the room, the lower area can be quickly heated to the desired temperature. Compared to existing cooling and heating units, when heating the lower area of the room to the required temperature, the temperature of the upper area of the room is higher than that of the lower area, resulting in heat waste. Therefore, the pipe arrangement in this application can heat the lower area of the room to the required temperature with less energy consumption.

[0049] In some embodiments, a second air outlet 23 is provided at one end of the telescopic exhaust pipe 2 away from the air supply assembly 1 , and a first baffle 24 for controlling the opening and closing of the second air outlet 23 is provided at the second air outlet 23 .

[0050] In this application, the second air outlet 23 is provided at the bottom of the telescopic tube 2, the top of which is connected to the air supply assembly 1. The opening and closing of the second air outlet 23 can be controlled by providing a first baffle 24. When the indoor temperature needs to be quickly adjusted, the air supply assembly 1 can be adjusted to maximum power, and then the first air outlet 21 and the second air outlet 23 are fully opened to increase the air output.

[0051] Specifically, when the cooling and heating unit is running in the rapid cooling mode, the extension length of the telescopic exhaust pipe 2 is adjusted, and after adjusting the height of the first air outlet 21 and the height of the second air outlet 23, the first air outlet 21 and the second air outlet 23 are all opened, and the air supply component 1 is turned on to the maximum power to quickly send cold air into the room, thereby achieving rapid cooling of the room.

[0052] When the cooling and heating unit is running in the rapid heating mode, adjust the extension height of the telescopic exhaust pipe 2, adjust the height of the first air outlet 21 and the second air outlet 23, open the first air outlet 21 and the second air outlet 23, turn on the air supply component 1 to the maximum power, and quickly send hot air into the room, thereby achieving rapid heating of the room.

[0053] In some embodiments, the pipe drainage device also includes a docking base 3, which is arranged on the extension path of the telescopic pipe 2. One end of the docking base 3 is connected to the floor heating system 4, and the other end is provided with a connection port 31, which is used to connect to the second air outlet 23.

[0054] In the present application, when the cooling and heating unit operates in the heating mode, the telescopic exhaust pipe 2 can also be extended to connect with the connection port 31 of the docking base 3. The air supply component 1 sends the hot air into the floor heating system 4 through the telescopic exhaust pipe 2 and the docking base 3, thereby heating the room through the floor heating system 4. The heat of the floor heating system 4 is from bottom to top, achieving heating of the entire room, which can ensure the temperature of the lower area of the room and the temperature of the indoor floor.

[0055] Specifically, the second air outlet 23 and the connecting port 31 can be connected by magnetic attraction, and a sealing structure is provided at the second air outlet 23 and the connecting port 31 to ensure the sealing effect of the connection, so as to ensure that the hot air can be fully delivered to the floor heating system 4.

[0056] In some embodiments, a second baffle 32 is provided at the connection port 31 of the docking base 3 , and the second baffle 32 is used to control the opening and closing of the connection port 31 .

[0057] In the present application, the second baffle 32 can be used to close the connection port 31 during normal operation, thereby preventing external impurities from entering the docking base 3, keeping the interior of the docking base 3 clean, and not affecting the normal use of the floor heating system 4. When hot air needs to be introduced into the floor heating system 4, the second air outlet 23 is connected to the connection port 31, and the first baffle 24 and the second baffle 32 are both opened to drain the water in the floor heating system 4 and send hot air into the floor heating system 4. The normal operation of the floor heating system 4 can be achieved without the need for external hot water.

[0058] In some embodiments, the pipe arrangement further includes a partition 5 disposed within the docking base 3. The partition 5 divides the interior of the docking base 3 into a supply air section 33 and a return air section 34, which are interconnected. The supply air section 33 and the return air section 34 are respectively connected to the air inlet and air outlet of the floor heating system 4, thereby allowing the air in the docking base 3 and the floor heating system 4 to circulate back. Specifically, the second baffle 32 is partially open. The open portion connects the connecting port 31 with the second air outlet 23, and the unopened portion is used to guide the air in the return air section 34 to the supply air section 33.

[0059] In this application, after the hot air enters the docking base 3, it first enters the floor heating system 4 through the supply air section 33, flows through the entire floor heating system 4 to achieve the purpose of floor heating heating, and then enters the return air section 34 from the air outlet of the floor heating system 4, and is re-merged into the supply air section 33 in the return air section 34, so that a hot air circulation reflux is formed in the floor heating system 4, which can fully utilize the heat, unlike the existing floor heating system 4, where the hot water still returns with a certain temperature after flowing through the floor heating system 4, thereby causing heat waste.

[0060] Furthermore, the air in the floor heating system 4 is not clean and is prone to breeding bacteria in a relatively closed environment. This application prevents the air in the floor heating system 4 from entering the room by forming a hot air circulation backflow between the floor heating system 4 and the docking base 3. Optionally, when the pressure inside the floor heating system 4 is too high, a pressure relief valve can be provided to relieve the pressure in the floor heating system 4, thereby discharging some of the gas in the floor heating system 4 to the outside through the pressure relief valve.

[0061] In some embodiments, the pipe arrangement further includes a water pan 6 , which is disposed in the air supply section 33 or in the floor heating system 4 , so that the hot air entering the floor heating system 4 can heat the water in the water pan 6 .

[0062] In this application, by setting up a water pan 6, hot air can evaporate the water in the water pan 6 into water vapor. By circulating the water vapor between the floor heating system 4 and the docking base 3, the heat exchange effect can be achieved, thereby improving the utilization rate of heat and reducing heat loss.

[0063] The exhaust pipe device adjusts the height of the first air outlet 21 by extending and retracting the telescopic exhaust pipe 2, and adjusts the air outlet direction at the first air outlet 21 through the fan blade assembly 22. During cooling, the height of the first air outlet 21 can be raised, and the first air outlet 21 can be made to discharge air downward, so that the cold air can settle from top to bottom in the room. During heating, the height of the first air outlet 21 can be lowered, and the air outlet direction of the first air outlet 21 can be adjusted, so that the hot air can flow from bottom to top in the room, thereby reducing the temperature difference at different heights in the indoor environment.

[0064] An embodiment of the present application provides a cooling and heating unit, comprising: an indoor unit and an outdoor unit; and the above-mentioned exhaust pipe device, wherein the air supply component of the exhaust pipe device is connected to the air outlet end of the indoor unit.

[0065] The cooling and heating unit in this application generates cooling or heating through the cooperation of the compressors of the indoor and outdoor units. The cooling or heating is then delivered to the telescopic pipe 2 by the air supply assembly 1. The height of the first air outlet 21 can be adjusted by extending and retracting the telescopic pipe 2. The opening and air supply direction of the first air outlet 21 can be adjusted by the fan assembly 22. The height and direction of the air supply can be adjusted according to demand, thereby achieving flexible air supply. Moreover, compared to the existing single-point air supply model, it can also achieve multi-point air supply in the vertical direction, ensuring more uniform air output in the vertical direction and ensuring uniform indoor temperature.

[0066] Figure 6 A flow chart of a floor heating unit control method provided in an embodiment of the present application is shown.

[0067] like Figure 6 As shown, the embodiment of the present application provides a control method for the above-mentioned cooling and heating unit, including:

[0068] S1. Obtain the operating mode of the cooling and heating units;

[0069] S2. According to the operation mode of the cooling and heating unit, the height of the first air outlet 21 of the telescopic exhaust pipe 2 is adjusted, and the air outlet direction at the first air outlet 21 is adjusted.

[0070] In this application, the extension length of the telescopic exhaust pipe 2 can be adjusted according to the operating mode of the cooling and heating unit to adjust the height of the first air outlet 21, and the angle of the fan blade assembly 22 can be adjusted to adjust the air volume and air outlet direction of the first air outlet 21. The air supply height and air supply direction can be adjusted according to needs to achieve flexible air supply.

[0071] Specifically, the control method includes:

[0072] S3. When the cooling and heating unit operates in cooling mode, the telescopic pipe 2 is extended to a first length and the angle of the fan blade assembly 22 is adjusted to a first angle so that the cold air blown out of the first air outlet 21 settles from top to bottom in the room;

[0073] S4. When the cooling and heating unit operates in heating mode, the telescopic exhaust pipe 2 is adjusted to a second length, and the angle of the fan blade assembly 22 is adjusted to a second angle, so that the hot air blown out of the first air outlet 21 flows from bottom to top in the room.

[0074] In the present application, when the cooling and heating unit is operating in cooling mode, the telescopic exhaust pipe 2 is extended to a first length, so that the first air outlet 21 is maintained at a relatively high height. The angle of the fan assembly 22 is then adjusted to a first angle, so that the air discharged from the first air outlet 21 can be discharged downward, thereby causing the discharged cold air to settle from top to bottom in the room, cooling the room. When the cooling and heating unit is operating in heating mode, the telescopic exhaust pipe 2 is extended to a second length, so that the first air outlet 21 is maintained at a relatively low height. The angle of the fan assembly 22 is then adjusted to a second angle, raising the air supply direction of the first air outlet 21, thereby causing the discharged hot air to flow from bottom to top in the room, achieving rapid heating of the lower area of the room.

[0075] In some embodiments, a second air outlet 23 is provided at one end of the telescopic exhaust pipe 2 away from the air supply assembly 1 , and a first baffle 24 for controlling the opening and closing of the second air outlet 23 is provided at the second air outlet 23 ; the control method further includes:

[0076] S5. When the cooling and heating unit operates in the rapid cooling mode, the telescopic pipe 2 is extended to the first length, the fan assembly 22 adjusts the first air outlet 21 to be fully open, and the first baffle 24 adjusts the second air outlet 23 to be fully open;

[0077] S6. When the cooling and heating unit operates in the rapid heating mode, the telescopic pipe 2 is extended to the second length, the fan blade assembly 22 adjusts the first air outlet 21 to be fully opened, and the first baffle 24 adjusts the second air outlet 23 to be fully opened.

[0078] In the present application, when the cooling and heating unit operates in a rapid cooling mode, the first air outlet 21 and the second air outlet 23 can be fully opened, the power of the air supply component 1 can be adjusted to the maximum, and the air output volume can be increased, thereby achieving rapid cooling of the room. When the cooling and heating unit operates in a rapid heating mode, the first air outlet 21 and the second air outlet 23 can be fully opened, the power of the air supply component 1 can be adjusted to the maximum, and the air output volume can be increased, thereby achieving rapid heating of the room.

[0079] In some embodiments, the pipe arrangement further includes a docking base 3, which is disposed on the extension path of the telescopic pipe 2. One end of the docking base 3 is connected to the floor heating system 4, and the other end is provided with a connection port 31, which is used to connect to the second air outlet 23. The control method further includes:

[0080] S7. When the cooling and heating unit operates in heating mode, the telescopic exhaust pipe 2 extends to the third length and connects to the connection port 31 of the docking base 3. The fan assembly 22 adjusts the first air outlet 21 to close, so that the hot air enters the floor heating system 4 through the second air outlet 23.

[0081] In the present application, when the cooling and heating unit is operating in the heating mode, the telescopic exhaust pipe 2 can also be extended to the maximum length. At this time, the telescopic exhaust pipe 2 is docked with the docking base 3 and closed through the first air outlet 21. The hot air from the cooling and heating unit enters the floor heating system 4 through the telescopic exhaust pipe 2 and the docking base 3, and the indoor temperature is increased by the floor heating system 4. The cooling and heating unit is combined with the floor heating system 4, and the floor heating system 4 can be operated without an external hot water source. Compared with direct blowing of hot air, the heating of the floor heating system 4 can avoid indoor dryness, and can prevent physical discomfort caused by direct blowing of hot air, thereby improving comfort.
