Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a heat storage belt, a roll-up heat storage device, an air conditioner and a control method thereof. Background Art

[0002] The defrosting process of an air conditioner usually affects the user's comfort. In defrost mode, heating is interrupted and even cooling needs to be started, causing the indoor temperature to drop and the waiting time to be long, making the user feel uncomfortable.

[0003] To address this issue, an existing air conditioner features a thermal storage tank. The refrigerant pipe continuously curves through the thermal storage tank, which houses multiple phase-change material cartridges. When the air conditioner is heating, heat from the refrigerant pipe is transferred to the phase-change material cartridges via the heat transfer medium within the thermal storage tank. The phase-change material undergoes a phase change from solid to liquid, storing heat. During defrosting, the solenoid valve in the thermal storage tank's refrigerant pipe opens, allowing low-temperature refrigerant to enter the refrigerant pipe, where it absorbs heat from the phase-change material. The heat released by the phase-change material is used to raise the temperature of the low-temperature refrigerant, defrosting the outdoor unit. This eliminates the need to shut down the indoor unit.

[0004] However, existing air conditioners with thermal storage tanks have a problem: during defrost, the indoor temperature remains heated, and the refrigerant in the outdoor unit's heat exchanger remains low. Relying solely on the heat from the thermal storage tank for defrosting results in low defrost efficiency and a low upper limit on defrost capacity. Therefore, ensuring both effective defrosting and user comfort has become a pressing technical challenge. Summary of the Invention

[0005] The first purpose of the present invention is to provide a retractable heat storage belt, which absorbs heat from the collecting pipe when retracted and can be unfolded and sent to the room, thereby solving the problem of indoor cooling and user discomfort while ensuring the defrosting effect.

[0006] The second purpose of the present invention is to provide a retractable heat storage device, which absorbs the heat from the collecting pipe when retracted and can be unfolded and sent to the room, thereby solving the problem of indoor cooling and user discomfort while ensuring the defrosting effect.

[0007] The third object of the present invention is to provide an air conditioner that solves the problem of indoor temperature reduction causing user discomfort while ensuring the defrosting effect.

[0008] A fourth object of the present invention is to provide a method for controlling an air conditioner, which solves the problem of user discomfort caused by indoor cooling while ensuring the defrosting effect.

[0009] The first object of the present invention provides a heat storage belt comprising a phase change material unit and a belt body, wherein the belt body is made of a flexible heat-conducting material, and a plurality of phase change material units are arranged in an array on an extended surface of the belt body; the heat storage belt can be changed between an unfolded state and a reeled state, and the inner periphery of the heat storage belt in the reeled state forms a tube setting position.

[0010] As can be seen from the above scheme, when rolled up, the heat storage belt wraps around the main gas collection pipe, absorbing some of the heat transferred from the main gas collection pipe through the heat absorption layer, thereby storing thermal energy. When the air conditioner is in defrost mode and heating is interrupted, the first air outlet closes, the heat storage belt is transformed into the unfolded state, and the air supply device blows the indoor warm air towards the heat storage belt, continuously radiating the warm air into the room. This ensures that the indoor temperature remains constant even in normal defrost mode (which requires stopping heating) or rapid defrost mode (which requires cooling), ensuring both the defrost effect and the user's comfort.

[0011] A further solution is that the outer surface and / or the inner surface of the belt body is provided with a plurality of grooves spaced apart along the unfolding line of the belt body, and the grooves pass through along the winding axis of the belt body.

[0012] As can be seen from the above, the arrangement of the grooves reduces the resistance to belt winding, and the thermal storage belt can be unfolded and wound more smoothly.

[0013] A further solution is that the heat storage belt further includes a tooth group, which is arranged on the outside of the belt body and extends along the unfolding line of the belt body.

[0014] As can be seen from the above, the tooth group is used to cooperate with the gear, and the motor can drive the heat storage belt to automatically unfold and reel.

[0015] The second object of the present invention provides a retractable heat storage device comprising the above-mentioned heat storage belt; further comprising a main body assembly, wherein a belt setting position is formed in the main body assembly, and the main body assembly is provided with a first outlet, the first outlet being connected to the belt setting position; the heat storage belt can be retracted in the belt setting position, and the heat storage belt can be unfolded outside the main body assembly through the first outlet; the main body assembly is provided with a pipe through hole, and the pipe through hole is connected to the pipe setting position along the axial direction of the reeling axis of the belt body.

[0016] As can be seen from the above scheme, the retractable heat storage device is installed outside the indoor unit's gas collection main pipe. When rolled up, the heat storage belt wraps around the gas collection main pipe, absorbing some of the heat transferred from the gas collection main pipe through the heat absorption layer, thereby storing thermal energy. When the air conditioner is in defrost mode and heating is interrupted, the first air outlet closes, the heat storage belt is converted to the unfolded state, and the air supply device blows the indoor warm air towards the heat storage belt, continuously radiating the warm air into the room. This ensures that the indoor temperature remains constant even in normal defrost mode, which requires stopping heating, or rapid defrost mode, which requires cooling. This ensures both the defrosting effect and the user's comfort.

[0017] A further solution is that it also includes a first drive unit and a first gear, and the first gear is driven to rotate by the first drive unit; the thermal storage belt also includes a tooth group, which is arranged on the outside of the belt body and extends along the unfolding line of the belt body; the first gear is engaged with the tooth group, and the first drive unit works to drive the thermal storage belt to switch between the unfolded state and the reeled state.

[0018] As can be seen from the above, the first driving unit can drive the heat storage belt to automatically unfold and reel.

[0019] A further solution is that the main body component includes two support seats, which are arranged opposite to each other along the axial direction of the winding shaft of the thermal storage belt; at least one support seat is provided with a spiral groove, the spiral groove is open toward the belt setting position, the spiral groove is connected to the first outlet, and a part of the thermal storage belt in the winding state is located in the spiral groove; at least one support seat is provided with a through hole for passing the pipe.

[0020] As can be seen from the above, the arrangement of the spiral groove ensures that the thermal storage belt can be rolled up and unfolded along the spiral line, thereby having better stability.

[0021] A further solution is to also include an insulation pipe; along the axial direction of the winding shaft, the insulation pipe is connected between the two support seats and communicated with the pipe through hole, and the insulation pipe is located at the inner periphery of the thermal storage belt in the winding state and the outer periphery of the pipe setting position.

[0022] As can be seen from the above, the insulation pipe set outside the gas collecting main pipe can better collect the heat of the gas collecting main pipe, and then transfer the heat to the rolled-up heat storage belt to ensure heat utilization.

[0023] A further solution is that a window is provided in the main component, and the belt setting position can be connected to the outside of the main component through the window; the main component includes a blocking member that is controllably opened and closed and is provided at the window.

[0024] As can be seen from the above, when the auxiliary heating mode is in operation, the blocking member can be controlled to open, and a portion of the rolled-up heat storage belt is exposed, and the heat stored in the heat storage belt can be used to supplement heat.

[0025] A further solution is to further include a second driving unit and a second gear, the second gear is driven to rotate by the second driving unit; the blocking member is slidably arranged, and a rack extending along the circumference of the blocking member is provided on the blocking member, and the rack is engaged with the second gear.

[0026] As can be seen from the above, under this setting, the opening and closing of the blocking member are automatically achieved by electronic control.

[0027] The air conditioner provided by the third purpose of the present invention includes an air collecting pipe, including the above-mentioned retractable heat storage device, and the air collecting pipe passes through the pipe through hole and the pipe setting position.

[0028] A further solution is that it also includes a machine body, a second air guide assembly and a second air supply device, the machine body is provided with a second air inlet, a second air outlet and a second air duct formed between the second air inlet and the second air outlet, the second air guide assembly is provided at the second air outlet, and the second air supply device is provided in the second air duct; the machine body is provided with a second outlet, the second outlet is connected to the first outlet, and the thermal storage belt in the expanded state extends to an external position outside the machine body through the second outlet; the second air outlet can be adjusted to an angle for discharging air toward the external position by controlling the second air guide assembly.

[0029] As can be seen from the above scheme, the machine body originally has a first air inlet, a first air supply device and a first air outlet. Now, a second air inlet, a second air duct, a second air outlet, a second air guide component and a second air supply device are added to the roll-up heat storage device. When the heat storage is unfolded, it is opened outside the machine body. By controlling the second air guide component to make the second air outlet discharge air toward the outside, and then controlling the second air supply device to operate, even if the defrost is stopped, the indoor air passes through the second air duct, is sent out from the second air outlet and is blown toward the heat storage belt to be heated, which can ensure that the indoor temperature remains unchanged.

[0030] A further solution is that the roll-up heat storage device is arranged in the second air duct, and after the blocking member is opened, the belt setting position is connected to the second air duct.

[0031] As can be seen from the above, under this setting, when running the auxiliary heating mode, the blocking member can be controlled to open, and a part of the rolled-up heat storage belt is exposed to the second air duct, and the heat stored in the heat storage belt can be used to supplement the heat.

[0032] The fourth object of the present invention provides a control method for an air conditioner, the air conditioner adopts the above-mentioned air conditioner; the control method includes: entering the defrost mode: closing the first air outlet; controlling the first drive unit to change the heat storage belt to an expanded state, controlling the second air guide assembly to adjust the second air outlet to an angle that can discharge air toward an external position, and controlling the operation of the second air supply device.

[0033] As can be seen from the above scheme, whether in normal defrost mode (with heating stopped) or rapid defrost mode (with cooling), simply closing the first air outlet ensures that airflow is delivered only through the second air outlet. Air delivered from the second air outlet is blown toward the heat storage area, where it is heated, ensuring that the indoor temperature remains constant. Therefore, the present invention ensures user comfort without sacrificing defrost efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The heat storage belt 1 includes a phase change material unit 12 and a belt body 11. The belt body 11 is made of a flexible, heat-conducting material. The phase change material unit 12 is arranged in a rectangular sheet shape. Multiple phase change material units 12 are arranged in a rectangular array on the extended surface of the belt body 11. The phase change material units 12 are enclosed by the belt body 11 and are not exposed on the surface of the belt body 11. The phase change material unit 12 undergoes a phase change from solid to liquid after absorbing heat, and changes from liquid to solid after releasing heat.

[0046] The belt body 11 has an inner side 101 and an outer side 102 on either side of its thickness. The heat storage belt 1 also includes a tooth set 13, which is disposed on the outer side 102 of the belt body 11 and extends along the unwinding line L of the belt body 11. Furthermore, a tooth set 13 is provided on both axial sides of the reeling axis C of the heat storage belt 1. The surface of the outer side 102 is provided with a plurality of grooves 111 spaced apart along the unwinding line L of the belt body 11. The grooves 111 extend along the reeling axis C of the belt body 11. In the y-axis direction, the belt body 11 includes a spacer between two adjacent rows of phase change material units 12. Preferably, the grooves 111 are provided in this spacer to prevent the belt body 11 from affecting its sealing and wrapping of the phase change material units 12.

[0047] in, Figures 1 to 3 A unified spatial rectangular coordinate system is established, and the extended surface of the unfolded and flattened heat storage belt 1 is parallel to the xy axis plane, as shown in FIG. Figures 1 to 3 As shown, the unfolding line L in the unfolded state is a straight line extending along the y-axis direction; Figure 5 As shown, the unwinding line L in the reeled state is a spiral line and the spiral line is located in a plane perpendicular to the reeling axis C. In the present invention, the reeling axis C is the center line of the thermal insulation tube 26 of the reel-type thermal storage device. The x-axis in the coordinate system represents the axial direction of the reeling axis C, and the axial direction of the reeling axis C is consistent with the width direction of the air conditioner body.

[0048] Recombination Figure 4 and Figure 5 The roll-up heat storage device includes a heat storage belt 1 and a main assembly 2. The main assembly 2 includes a support base 21, a heat-insulating shell 22, a blocking member 23, a first drive unit 24, a first gear 241, a second drive unit 25, a second gear 251, and a heat-insulating tube 26. The support base 21, the first drive unit 24, the first gear 241, the second drive unit 25, and the second gear 251 are each two.

[0049] The two support seats 21 are axially symmetrical. A through-hole 210 is provided on each support seat 21. The centerline of the through-hole 210 is the winding axis C. The through-hole 210 extends through opposite sides of the support seat 21 along the axial direction of the winding axis C. Along the axial direction of the winding axis C, the side of the support seat 21 opposite to the other support seat 21 is the inner side. The support seat 21 includes a spiral groove 211 and a slide groove 213 provided on the inner side. Both the spiral groove 211 and the slide groove 213 are open along the axial direction of the winding axis C. The spiral groove 211 is provided around the through-hole 210, and the end of the spiral groove 211 extending along its own spiral line also forms a second outlet portion 2201b that communicates with the outside of the main assembly 2. The slide groove 213 is provided on the outer periphery of the spiral groove 211, and the center of the slide groove 213 is parallel to the center of the through-hole 210.

[0050] The insulation shell 22 is a cylindrical structure with a notch. The insulation shell 22 is actually composed of a first plate body 22a and a second plate body 22b that are separated from each other. A first outlet portion 2201a connected to the outside of the main body component 2 is formed between the lower sides of the first plate body 22a and the second plate body 22b, and a window 2202 connected to the outside of the main body component 2 is formed between the upper sides of the first plate body 22a and the second plate body 22b.

[0051] The blocking member 23 is a plate made of insulating material. Racks 231 extending circumferentially along the blocking member's axis are provided at both axial ends. The blocking member's axis is parallel to the axis of the reel C. Two support seats 21 are connected to the insulation shell 22 on either axial side, forming a belt-setting position 220 between the two support seats 21 and the inner circumference of the insulation shell 22. The blocking member 23 is mounted on either axial side in two slide grooves 213 of the two support seats 21. A second drive unit 25 is fixedly mounted on the support seat 21. The rack 231 of the blocking member 23 meshes with a second gear 251. Driven by the second drive unit 25, the blocking member 23 is controllably opened and closed at a window 2202 on the outer periphery of the belt-setting position 220. The blocking member 23 can move between a position blocking the window 2202 and a position opening the window 2201.

[0052] Furthermore, the two second outlet portions 2201b and the first outlet portion 2201a form a first outlet 2201, which communicates between the belt setting position 220 and the exterior of the main assembly 2. Furthermore, the thermal insulation tube 26 is axially connected between the two support seats 21, and the thermal insulation tube 26 communicates with the two through-holes 210, forming a passage through the thermal storage device for the passage of the gas collecting pipe.

[0053] The heat storage belt 1 is set in the belt setting position 220. In particular, the opposite sides of the winding shaft C of the heat storage belt 1 are respectively set in the spiral grooves 211 of the two support seats 21, and at least the tail of the heat storage belt 1 extends to the outside of the main assembly 2 through the first outlet 2201. Figure 6 When the heat storage belt 1 is in the reeled state, the majority of the heat storage belt 1 is reeled in the belt mounting position 220 and along the spiral groove 211. Only the tail portion of the heat storage belt 1 extends out of the main assembly 2 through the first outlet 2201. At this point, the thermal insulation tube 26 is located within the inner periphery of the reeled heat storage belt 1 and outside the tube mounting position 10.

[0054] The first driving unit 24 is fixedly mounted on the support base 21 , and the tooth set 13 on the heat storage belt 1 is engaged with the first gear 241 . Thus, driven by the first driving unit 24 , the heat storage belt 1 can change along the spiral groove 211 between a retracted state and an unreeled state.

[0055] See also Figure 5 and Figure 6 The air conditioner includes an air collecting pipe 8 and a body 9. The air collecting pipe 8 is the main air collecting pipe of the indoor unit. The body 9 includes a shell, a first air supply device 94 and a first air guide assembly 95 of the existing indoor unit. The shell is provided with a first air inlet 9110 and a first air outlet 9120 of the existing shell. The first air inlet 9110 is located at the top of the body 9 and the first air outlet 9120 is located at the bottom front of the body 9. The first air supply device 94 is a cross-flow fan, and the first air guide assembly 95 is an air guide plate assembly that can be opened and closed at the first air outlet 9120.

[0056] The air conditioner of the present invention also includes a rollable heat storage device, a second air guide assembly 93, and a second air supply device 3. Furthermore, the outer casing is provided with a second air inlet 9210 and a second air outlet 9220.

Furthermore, the housing 9 includes a second air duct 920 formed between the second air inlet 9210 and the second air outlet 9220. The second air supply device 3 is disposed in the second air duct 920. Specifically, the second air supply device 3 includes an exhaust turbine assembly, and three second air supply devices 3 are spaced apart along the width of the housing 9. Furthermore, the rollable heat storage device is disposed in the second air duct 920. When the blocking member 23 is opened, the heat storage belt in the belt setting position 220 communicates with the second air duct 920 through the window 2202. The gas collecting pipe 8 passes through the pipe through hole 210 and the pipe setting position 10 and is located in the thermal insulation pipe 26.

[0058] Embodiment of a control method for an air conditioner The air conditioner adopts the air conditioner of the above-mentioned air conditioner embodiment.

[0059] See also Figure 7 and Figure 8 In the initial state, the air conditioner is running in heating mode, and the heat storage belt 1 is in the rolled-up state.

[0060] Control methods include: The air conditioner system executes step S1 and determines to enter the normal defrost mode according to the input instruction or the automatic judgment result: First, step S2 is executed to control the first air supply device 94 to stop, and the first air guide component 95 to close the first air outlet 9120.

[0061] Then, step S3 is executed to control the first driving unit 24 to unfold the heat storage belt 1 to the unfolded state and reach the external position 909, and control the second air guide assembly 93 to adjust the second air outlet 9220 to an angle capable of blowing air toward the external position 909 where the heat storage belt 1 is located.

[0062] Then, step S4 is executed to stop the heating operation, and finally step S5 is executed to start the second air supply device 3.

[0063] See also Figure 7 and Figure 9 In the initial state, the air conditioner is running in heating mode, and the heat storage belt 1 is in the rolled-up state.

[0064] Control methods include: The air conditioner system executes step S11, and when it is determined to enter the rapid defrost mode according to the input instruction or the automatic judgment result: First, step S12 is executed to control the first air guide assembly 95 to close the first air outlet 9120 .

[0065] Then, step S13 is executed to control the first driving unit 24 to unfold the heat storage belt 1 to the unfolded state and reach the external position 909, and control the second air guide assembly 93 to adjust the second air outlet 9220 to an angle capable of blowing air toward the external position 909 where the heat storage belt 1 is located.

[0066] Then, step S4 is executed to start the cooling operation. Finally, step S5 is executed to start the second air supply device 3.

[0067] In the air conditioner and control method thereof of the present invention, the initial heat storage belt 1 wraps around the gas collecting main pipe when rolled up, and absorbs part of the heat transferred by the gas collecting main pipe through the heat absorption layer to store thermal energy. When the air conditioner is running for heating and needs to be defrosted, whether it is ordinary defrosting or rapid defrosting, when the air conditioner is interrupted from heating in the defrosting mode, the first air outlet 9120 is closed, the heat storage belt 1 is converted to the unfolded state, and the air supply device blows the indoor warm air to the heat storage belt 1, and continuously radiates the warm air into the room. In this way, even in the ordinary defrosting mode where the heating operation needs to be stopped or the rapid defrosting mode where the cooling operation needs to be stopped, it can be ensured that the indoor temperature remains unchanged. The air conditioner of the present invention uses its own heat storage device, which can serve as an alternative heat source to continuously supply hot air to the room during the defrosting period of the air conditioner, thereby avoiding the indoor temperature from dropping and maintaining the user's comfort. That is, it ensures both the defrosting effect and the user's physical sensation.

[0068] Furthermore, the control method further includes, before entering the defrost mode: When the temperature of the refrigerant pipe of the outdoor heat exchanger is detected to be lower than the preset temperature threshold, the air conditioner will automatically enter the defrost mode if the temperature of the refrigerant pipe of the outdoor heat exchanger is still lower than the preset temperature threshold after the preset time. For example, the temperature of the refrigerant pipe is detected once every 0.5 hours. When the temperature of the refrigerant pipe is lower than -8℃, the air conditioner will continue to monitor for 60 seconds. If the monitoring value is still lower than -8℃, the air conditioner will enter the defrost mode. Figure 8 Normal defrost mode or Figure 9 The fast defrost mode is shown.

[0069] See also Figure 7 and Figure 10 The air conditioning system executes step S21, and the air conditioning system operates in heating mode. At this point, the heat storage belt 1 is in the retracted state. Next, step S22 is executed, controlling the second drive unit 25 to open the window 2202. Finally, step S23 is executed, controlling the second air supply device 3 to activate and the second air guide assembly 93 to open the second air outlet 9220 and supply air downward. When the air conditioner indoor unit is in normal heating mode, the heat storage device is used to provide dual heat sources and multi-angle heating. When the heating mode is running, the first air supply device 94 rotates and the first air outlet 9120 is opened. The air conditioner indoor unit delivers warm air to the central area of the room through the original air supply angle of the first air outlet 9120. The heat storage belt 1 remains in a rolled-up state and the window 2202 is opened. Part of the heat absorption layer of the heat storage belt 1 is exposed to the second air duct 920. At the same time, the second air supply device 3 is started to extract indoor warm air and blow it through the second air duct 920 where the heat storage belt 1 is exposed, and then guide it back to the indoor environment from the second air outlet 9220 at a low angle. In this way, the indoor temperature can be evenly distributed in all directions, allowing users to quickly feel warm and greatly improving the user experience.

[0070] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
