[0029] Please see Figures 1-10This utility model discloses a cross-flow heater with humidifier function. The cross-flow heater includes two side plates 10 arranged in parallel, a back plate 20 and a tongue plate 30 installed at the opposite ends of the two side plates 10. In this embodiment, the back plate 20 and the tongue plate 30 are located at the front and rear ends of the side plates 10 and are spaced apart, and the two side plates 10, the back plate 20 and the tongue plate 30 together form the cross-flow air duct 50. A heating element 60 extending along the path direction is provided inside the cross-flow duct 50, and an airflow conveying device 80 is also provided along the path of the cross-flow duct 50. The airflow conveying device 80 is used to generate airflow in the cross-flow duct 50, which enters from the air inlet 53 of the cross-flow duct 50 and exits from the air outlet 54 of the cross-flow duct 50. A liquid storage tank 100 is provided on the outer surface of the back plate 20, and a spray nozzle 101 is provided at the upper end of the liquid storage tank 100. The heat generated by the heating element 60 can heat the liquid in the receiving cavity 103 of the liquid storage tank 100 through the back plate 20 and produce atomized material. The atomized material diffuses outward from the spray nozzle 101 to humidify the surrounding environment. A viewing window 102 is provided on the outer wall of the liquid storage tank 100 for observing the remaining liquid in the liquid storage tank 100.

[0030] In this embodiment, the heating element 60 is disposed on the back plate 20 so that the heat generated by the heating element 60 can be transferred to the liquid in the liquid storage tank 100 through the back plate 20. The liquid in the liquid storage tank 100 generates atomized material after being heated. The atomized material diffuses outward from the spray nozzle 101 to humidify the surrounding environment. Furthermore, the liquid in the liquid storage tank 100 is an aqueous solution.

[0031] In another embodiment, at least one end of the heating element 60 is disposed on one side of the side plate 10 and the other end extends into the cross-flow duct 50, or the other end is disposed on the other side of the side plate 10. The heating element 60 is spaced between the back plate 20 and the tongue plate 30 to divide the cross-flow duct 50 into a main duct 51 and a secondary duct 52. Heat is generated on both sides of the heating element 60, and the heat generated on both sides of the heating element 60 diffuses into the main duct 51 and the secondary duct 52, respectively. More specifically, the main duct 51 is located between the heating element 60 and the tongue plate 30, and the secondary duct 52 is located between the heating element 60 and the back plate 20. In this embodiment, the distance between the heating element 60 and the tongue plate 30 is greater than the distance between the heating element 60 and the back plate 20. More specifically, in this embodiment, the two side panels 10, the heating element 60, and the tongue plate 30 together form the main air duct 51; the two side panels 10, the heating element 60, and the back plate 20 together form the secondary air duct 52. Therefore, all the heat generated in the main air duct 51 is discharged from the air outlet 54 of the cross-flow air duct 50 for consumer use; the heat generated in the secondary air duct 52 is partially used to transfer to the water stored in the liquid storage tank 100 for atomization, and the remaining heat is discharged from the air outlet 54 of the cross-flow air duct 50 for consumer use.

[0032] In this invention, the heating element 60 is isolated from the aqueous solution in the storage tank 100 by the back plate 20. The advantage is that it prevents the heating element 60 from being directly heated by contact with the aqueous solution, which would cause surface calcification and impurities to adhere to the surface of the heating element 60, ultimately affecting the heat output of the heating element 60.

[0033] Please see Figures 3-6 The back plate 20 includes a first extension 21 and a second extension 22 that are connected to each other, and the first extension 21 and the second extension 22 are arranged at an angle.

[0034] The heating component 60 includes two interconnected heating units. Each heating unit includes a heating plate 61 extending in a plane and at least one heat sink 62 disposed on each heating plate 61. A heat-conducting unit 63 is disposed between the heat sink 62 and the heating plate 61. In this embodiment, the heating plate 61 is a thick-film heating plate.

[0035] The heating component 60 includes a first heating plate 611 and a second heating plate 612 that are connected to each other and arranged at the same angle to the back plate. The first heating plate 611 is arranged parallel to the first extension section 21, and the second heating plate 612 is arranged parallel to the second extension section 22.

[0036] In this embodiment, the first extension 21 and the second extension 22 of the back plate 20 are set at an angle, and the first heating plate 611 and the second heating plate 612 of the heating component 60 are also designed at the same angle. This allows the heat generated by the heating component 60 to remain at the connection between the first extension 21 and the second extension 22 and be transferred through the back plate 20 to the receiving cavity 103 of the liquid storage tank 100. This ensures that the heat transferred from the heating component 60 to the liquid storage tank 100 is sufficient to atomize the aqueous solution, thereby generating atomized material that is sprayed out from the spray nozzle 101 to humidify the surrounding environment.

[0037] Please see Figure 10 The tongue plate 30 includes a first extension section 31 and a second extension section 32 connected to each other. The first extension section 31 is arranged parallel to the first extension section 21, and the second extension section 32 is arranged parallel to the second extension section 22. The tongue plate 30 also includes a guide extension section 33 connected to the first extension section 31. The tail end of the guide extension section 33 is arranged to expand outward at the air inlet end of the cross-flow duct 50 to facilitate the airflow entering the cross-flow duct 50 from the air inlet end of the cross-flow duct 50.

[0038] Please see Figure 8 and Figure 9 In this embodiment, the first heating plate 611 and the second heating plate 612 are thick-film heating plates. The thick-film heating plates are printed with resistive circuits. The resistive circuits are disposed on the side facing the back plate 20. The resistive circuits of the thick-film heating plates are the core area for generating heat. They face the back plate so as to facilitate the rapid transfer of the heat generated by the resistive circuits to the aqueous solution in the liquid storage tank 100, so that it is atomized and discharged from the spray nozzle 101 to humidify the surrounding environment.

[0039] Furthermore, a first radiator 621 is mounted on the first heating plate 611, and a second radiator 622 is mounted on the second heating plate 612. The first radiator 621 is mounted on the first heating plate 611 facing the tongue plate 30, and the second radiator 622 is mounted on the second heating plate 612 facing the tongue plate 30. Additionally, a heat-conducting unit 63, which is a graphite sheet, is installed between the first heating plate 611 and the first radiator 621, and between the second heating plate 612 and the second radiator 622.

[0040] In one embodiment, a protective film 64 is also covered on one side of the resistive circuit of the thick film heating plate. The protective film 64 is used to prevent dust, impurities and the like from adhering to the surface of the resistive circuit and affecting the heat generation of the thick film heating plate. In addition, dust, impurities and the like may be conductive and reduce the insulation performance of the thick film heating plate.

[0041] Please see Figures 1-5 In this embodiment, the airflow conveying device 80 is a cross-flow fan, which is rotatably mounted between the two side plates 10. Furthermore, the cross-flow heater also includes a drive motor 90 for driving the cross-flow fan to rotate. The drive motor 90 is mounted on the side plate 10, and its drive shaft is fixedly connected to the cross-flow fan and can drive the cross-flow fan to rotate around the axis of the drive shaft to generate driving force to transport the airflow within the cross-flow duct 50 to the air outlet of the cross-flow duct 50.

[0042] This utility model provides a cross-flow heater with humidification function. When operating, it humidifies the surrounding environment, preventing excessive dryness caused by prolonged heat generation from the heater's heating unit. This ensures that consumers will not experience dry skin or cracking even in dry environments heated by the heater for extended periods, making it popular with consumers. Furthermore, the design of the viewing window 102 in the liquid storage tank 100 allows for real-time monitoring of the remaining liquid level in the containing cavity 103, preventing dry burning.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model 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 this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
