Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] In a first aspect, the present invention provides a panel structure comprising:

[0011] Furthermore, the depth of the first water tank is close to and less than the height of the first panel body wall.

[0013] Furthermore, the depth of the second water tank is close to and less than the height of the cross frame.

[0014] Furthermore, the condensate tank includes a third water tank, which is excavated inside the second panel. A second partition is provided inside the third water tank to divide it into two independent third water tanks. An inlet and an outlet are respectively provided on the second panel corresponding to the positions of the two third water tanks. A first through-hole is provided in the third water tank connected to the inlet, and the first through-hole is directly opposite to the first inlet. A second through-hole is provided in the third water tank connected to the outlet, and the second through-hole is directly opposite to the first outlet.

[0015] Furthermore, the outlet is vertically higher than the inlet.

[0016] Furthermore, the outlet is 2-3 mm higher than the inlet.

[0017] Furthermore, the thermoelectric power generation module includes a thermoelectric power generation element and an energy storage component. The thermoelectric power generation element is attached to the inner wall of the first panel body, the side wall of the cross frame, and / or the inner wall of the second panel body; the energy storage component is electrically connected to the thermoelectric power generation element.

[0018] The panel structure provided by this invention recovers the heat energy generated by the outdoor unit and converts it into electrical energy by using thermoelectric power generation, thereby improving the overall energy utilization rate.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0043] like Figure 1 and Figure 2 As shown, the present invention provides a panel structure, including:

[0044] The first panel 1 is disposed at the air outlet end of the device to allow hot air to flow through; specifically, in this embodiment, as follows: Figure 1 As shown, the first panel 1 is installed on the air outlet side of the outdoor unit, that is, the front side of the outdoor unit. The heat generated by the condenser inside the outdoor unit is extracted by the axial fan inside the outdoor unit and blown to the external environment through the first panel 1, such as... Figure 2As shown, in order to prevent external debris from damaging the internal equipment of the outdoor unit, a grille structure is provided on the front side of the first panel 1.

[0045] The second panel 2 presses over the top of the first panel 1 to form the top cover of the equipment; that is, as... Figure 1 and Figure 2 As shown, the second panel 2 is the top cover of the outdoor unit.

[0046] A condensate tank is provided inside the first panel 1 and the second panel 2 to allow condensate to flow through the inside of the first panel 1 and the second panel 2 to exchange heat with the thermoelectric power generation module inside the first panel 1 and the second panel 2.

[0047] In this invention, in order to facilitate the installation of the condensate drain, the thickness of the second panel body 2, which serves as the top cover, is increased compared to the top cover of a traditional air conditioner, so as to facilitate the opening of a water drain inside the second panel body 2 and to facilitate the flow of condensate.

[0048] Thermoelectric power generation module is arranged on the first panel 1 and the second panel 2 to generate electricity by utilizing the temperature difference between condensate and hot air flow, or to cool down and dissipate heat when powered on.

[0049] The panel structure provided by this invention recovers the heat energy generated by the outdoor unit and converts it into electrical energy by using thermoelectric power generation, thereby improving the overall energy utilization rate. At the same time, energizing the thermoelectric generator can generate cooling, improving the operation of the outdoor unit in cooling mode.

[0050] Furthermore, in this embodiment, the condensate tank includes a first tank 3, a second tank 4, and a third tank 5. All condensate tanks are used for heat exchange through the flow of condensate. The first tank 3 is excavated inside the entire circumference of the side wall of the first panel 1, that is, the first tank 3 is arranged along the entire circumference of the first panel 1. Figure 10 As shown, it also includes a first inlet 6 and a first outlet 7 disposed on the first panel body 1 for communicating with the first water tank 3, and a first partition 8 is arranged in the first water tank 3 between the first inlet 6 and the first outlet 7 to separate the water tanks. Figure 11 As shown, the width of the first partition 8 is equal to the width of the first water tank 3, and the height of the first partition 8 is equal to the height of the first panel 1. The first partition 8 separates the entire first water tank 3 at the first partition 8, and the first inlet 6 is located at the beginning of the first water tank 3, close to the first partition 8. Condensate enters the first water tank 3 through the first inlet 6, and then flows along the entire first panel 1 to the first outlet 7 located on the other side of the first partition 8, so that the condensate flows out of the first water tank 3 through the first outlet 7.

[0051] For ease of setup and processing, the depth of the first water tank 3 is close to and less than the height of the wall of the first panel body 1. During processing, a groove can be cut into the wall of the first panel body 1, and then a cover plate can be placed on top to seal the first water tank 3 into a sealed water tank. Of course, other methods can also be used to process the first water tank 3, and no specific limitation is made here.

[0052] Furthermore, such as Figure 2 , 4 and Figure 8 As shown, in order to further recover waste heat and fully recover the heat in the hot airflow, a cross frame 9 is provided inside the air outlet cavity of the first panel body 1 to divide the inner cavity of the first panel body 1 into four independent air outlet cavities; as Figure 4 and Figure 8 As shown, the second water tank 4 is excavated inside the horizontal and vertical frame plates of the cross frame 9, and the two ends of the second water tank 4 are respectively connected to the first water tank 3. With this structure, the condensate entering through the first inlet 6 will circulate in the second water tank 4 in addition to the first water tank 3, thereby maximizing the contact area with the hot air flow and increasing the contact area of ​​the thermoelectric power generation module.

[0053] Furthermore, to maximize contact, the depth of the second water tank 4 is close to and less than the height of the cross frame 9. It should be noted that the second water tank 4 can also be manufactured using the same method as the first water tank 3 described above; no specific limitation is made here.

[0054] Furthermore, such as Figure 2 , 3 As shown in Figures 5 and 9, the third water tank 5 is excavated inside the second panel body 2. In fact, the second panel body 2 is a hollow structure, and the third water tank 5 is the cavity inside the second panel body 2. The shape of this cavity is the same as that of the second panel body 2. To improve heat exchange efficiency, the length and width of the third water tank 5 are close to and smaller than the length and width of the second panel body 2. The optimal implementation is that the inner wall thickness of the second panel body 2 is thinner than the outer wall thickness. Of course, they can also be set to be the same thickness, or the outer wall to be thicker than the inner wall; no specific limitation is made here, but the optimal method is still that the inner wall is thinner than the outer wall. To facilitate the inflow and outflow of condensate, a second partition 10 is provided inside the third water tank 5 to divide the third water tank 5 into two independent third water tanks 5. The second panel body 2 has an inlet 11 and an outlet 12 corresponding to the positions of the two third water tanks 5, respectively. Figure 5As shown, a first through-hole 13 is provided in the third water tank 5 connected to the inlet 11. The first through-hole 13 is directly opposite to the first inlet 6, so that after the condensate enters the third water tank 5 through the inlet 11, it can flow out through the first through-hole 13, then enter the first water tank 3 through the first inlet 6, and then flow through the first water tank 3 and the second water tank 4 before flowing out through the first outlet 7. A second through-hole 14 is provided in the third water tank 5 connected to the outlet 12. The second through-hole 14 is directly opposite to the first outlet 7, so that the condensate flowing out through the first outlet 7 can enter the second through-hole 14, and then flow through the third water tank 5 before being discharged through the outlet 12.

[0055] Furthermore, in order to ensure that the condensate tank is full of water, the outlet 12 is vertically higher than the inlet 11.

[0056] Furthermore, the outlet 12 is 2-3 mm higher than the inlet 11.

[0057] like Figure 2 , 3 As shown in Figures 4, 6, 8, 9, and 11, the thermoelectric power generation module further includes a thermoelectric power generation element 15 and an energy storage component. The thermoelectric power generation element 15 is attached to the inner wall of the first panel body 1, the side wall of the cross frame 9, and / or the inner wall of the second panel body 2. The energy storage component is electrically connected to the thermoelectric power generation element 15.

[0058] like Figure 3 As shown, in this embodiment, the energy storage component is a battery module 18, installed inside the second panel 2 and located at the top of the third water tank 5. Of course, the energy storage component can also be placed in other locations, and no specific limitation is made here.

[0059] In this embodiment, there are 17 thermoelectric generators 15 in total. Eight of them are attached to the inner wall of the first panel body 1, another eight are attached to the side wall of the cross frame 9, and the last one is attached to the inner wall of the second panel body 2 facing the first panel body 1.

[0060] like Figure 1 and Figure 3 As shown, the present invention provides an outdoor unit, including a casing, a condenser, a fan, panel structures disposed on the rear and top sides of the casing, and temperature sensors disposed on the inner and outer sides of the casing, specifically, as shown... Figure 3 As shown, the temperature sensing element includes an inner temperature sensing element 16 and an outer temperature sensing element 17.

[0061] The outdoor unit provided by the present invention uses a thermoelectric generator 15 and a condensate drain tank installed at the rear air outlet panel and the top cover. By using the hot air blown out by the outdoor unit of the air conditioner and the condensate generated by the indoor unit, a large temperature difference is formed on both sides of the semiconductor generator, generating electricity and storing the electricity in the battery pack. The electricity in the battery pack can power other household appliances or the air conditioner, thereby improving energy efficiency.

[0062] The present invention provides an air conditioner, including the outdoor unit described above.

[0063] Thermoelectric power generation is a technology that directly converts heat energy into electrical energy using thermoelectric conversion materials based on the Seebeck effect. When a temperature difference occurs between the two ends of the semiconductor material inside the thermoelectric generator, an electromotive force (EMF) is generated, and the greater the temperature difference, the higher the EMF. Based on this, this invention utilizes the hot air blown out by the outdoor unit of an air conditioner and the condensate produced by the indoor unit to create a large temperature difference between the two sides of the semiconductor generator, generating electricity. This electricity is stored in a battery pack, which can then power other household appliances or the air conditioner, improving energy efficiency. The specific implementation method is as follows:

[0064] In cooling mode, the outdoor unit uses an axial fan to blow the heat generated by the condenser through the first panel 1 of the outdoor unit. This invention increases the thickness of the first panel 1 (this thickness refers to...). Figure 3 (As shown in the horizontal specifications from left to right), the contact area between the thermoelectric generator 15 and the hot airflow is increased, and a cross-shaped frame 9 structure is added in the middle. The thermoelectric generator 15 is designed on the inner wall, and a condensate drain is added between the inner and outer walls of the first panel 1. Condensate drains are also provided between the cross-shaped frames 9. Figure 3As shown, the second panel 2 has an inlet 11 and an outlet 12 on its upper part. A second baffle 10 is installed in the third water tank 5 between the inlet 11 and the outlet 12. Condensate flows from the inlet 11 into the condensate tank (third water tank 5) and finally flows out from the outlet 11. The outlet 12 is 2-3mm higher than the inlet, allowing the condensate tank to be filled with condensate. Two condensate pipes are connected to the inlet 11 and the outlet 12 respectively to facilitate the inflow and outflow of condensate. The condensate pipe connected to the inlet 11 is connected to the drain pipe of the indoor unit, and the condensate pipe connected to the outlet 12 is connected to the drain pipe of the indoor unit. This structure allows the condensate generated by the indoor unit to flow into the outdoor unit. The outlet drains the condensate that has flowed through the outdoor unit, preventing the condensate from being discharged directly from the outdoor unit. The second baffle 10 is installed in the middle of the condensate tank inside the second panel 2. Condensate flows into the second panel 2 from the right and flows out from the left. When hot air is blown out from the first panel 1, it passes over the outer surface of the thermoelectric generator 15, raising its temperature. Simultaneously, cooler condensate generated in the indoor cooling mode flows in the condensate tank, lowering the temperature of the inner surface of the thermoelectric generator 15. This creates a significant temperature difference between the inner and outer surfaces of the thermoelectric generator 15, generating electricity. The electricity generated by the thermoelectric generator 15 is stored in the battery module. The stored electricity can be supplied to power appliances such as electric water heaters, and can also power the thermoelectric generator 15 in reverse. Furthermore, when current is applied from different ports, the inner and outer surfaces of the thermoelectric generator 15 will produce different effects, achieving cooling on one side and heating on the other.

[0065] Thermoelectric element 15 structure as follows Figure 6 As shown, the electricity generated by the thermoelectric generator 15 is output to the battery module through ports A and B. Simultaneously, the electricity stored in the battery module can also be input to the thermoelectric generator through ports A and B. When electricity is input from port A, the outer surface of the thermoelectric generator absorbs heat from the outside environment. The absorbed heat is released through the inner surface, and the released heat can be absorbed by the condensate in the water tank. Through the heat absorption and release of the thermoelectric generator, the heat generated by the outdoor unit can be output more quickly, improving the cooling capacity of the air conditioner in high-temperature environments.

[0066] like Figure 7 As shown, the present invention provides a control method for recovering waste heat or cooling the aforementioned air conditioner, comprising:

[0067] The air conditioner is switched to cooling mode; at this time, the outdoor unit condenser generates heat, which is blown out by the axial fan and sent to the outside environment through the grille structure on one side of the first panel 1; in order to achieve waste heat recovery, the heat in this part of the airflow is reused.

[0068] The outdoor unit temperature T1 and the ambient temperature T2 are obtained by using an internal temperature sensor and an external temperature sensor, respectively.

[0069] Based on the acquired outdoor unit temperature T1 and ambient temperature T2, the temperature is compared with the set temperature value T. Based on the comparison result, the thermoelectric power generation module is controlled to perform waste heat recovery or rapid cooling.

[0070] Furthermore, based on the acquired outdoor unit temperature T1 and ambient temperature T2, a comparison is made with the set temperature value T. Based on the comparison result, the thermoelectric power generation module is controlled to perform waste heat recovery or rapid cooling, including:

[0071] When T > T1-T2, waste heat recovery is performed. The thermoelectric generator in the thermoelectric generator module uses the temperature difference between the condensate generated by the indoor unit and the hot air flow generated by the outdoor unit to start the power generation mode, and transmits the generated electricity to the energy storage component (battery module) in the thermoelectric generator module through the A and B ports on the thermoelectric generator 15.

[0072] When T≤T1-T2, rapid cooling is performed. The energy storage component supplies power to the thermoelectric generator, which absorbs the heat generated by the outdoor unit and discharges it through the condensate generated by the indoor unit.

[0073] Control principle such as Figure 7 As shown, a temperature sensor is installed on the inner and outer sides of the first panel 1 of the outdoor unit, respectively, to monitor the internal temperature of the outdoor unit and the ambient temperature outside the outdoor unit. By determining whether the internal temperature of the outdoor unit and the ambient temperature are lower than a certain critical set temperature value T, it is determined whether to supply power to the thermoelectric generator to accelerate the heat dissipation of the outdoor unit.

[0074] By utilizing the working principle of thermoelectric generators, the heat energy generated by the air conditioner is recovered and used to generate electricity. The generated electricity is stored in batteries, and the electrical energy in the batteries can power other household appliances, as well as the air conditioner and thermoelectric generators, thereby improving the working environment of the air conditioner, increasing its operating efficiency, and improving the operating environment of the outdoor unit.

[0075] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
