[0016] In order to enable those skilled in the art of the present technology to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. As Figure 1 and Figure 2 shown, an air conditioner unit with integrated heating and humidification includes a protective outer shell 1, a filtering section 2, a heat exchange coil section 3, a heating and humidification section 4, and a blower 5. The protective outer shell 1 is a through-type structure with openings on both left and right sides and is made of stainless steel as a whole. The filtering section 2 is located inside the protective outer shell 1 near the air inlet. The filtering section 2 uses a four-peak bag filter to intercept impurities in the air. Along the air inlet direction, the heat exchange coil section 3 is located behind the filtering section 2 to preprocess the filtered gas. The heating and humidification section 4 is located behind the heat exchange coil section 3. The heating and humidification section 4 includes a fixed outer shell 410, a water receiving tray 420, and a steam generator 430. The water receiving tray 420 is located below the fixed outer shell 410. The fixed outer shell 410 is a hollow structure that is wider at the top and narrower at the bottom and has a funnel shape. The steam generator 430 is located inside the fixed outer shell 410 to generate saturated steam for heating and humidifying the air. The blower 5 is located behind the heating and humidification section 4 near the air outlet and attracts air into the machine body by generating negative pressure.

[0017] As shown Figure 2 in the figure, the steam generator 430 includes a make-up water pipe 431, a steam drum 432, an electric heater 433, an intake pipe 434, a heat exchange drum 435, an exhaust pipe 436 and a fixing clip 437. One end of the make-up water pipe 431 is connected to the steam drum 432, and the other end passes through the fixing housing 410 and is connected to the protective housing 1. The make-up water pipe 431 is made of metal as a whole to fix the steam drum 432 inside the fixing housing 410. The electric heater 433 is installed on the inner wall of the steam drum 432. Most of the space in the steam drum 432 is filled with water, and the electric heater 433 is immersed in the water. One end of the intake pipe 434 is connected to the top end of the steam drum 432, and the other end extends deep into the heat exchange drum 435. Most of the space in the heat exchange drum 435 is filled with water and submerges the deep part of the intake pipe 434. The surface of the end of the intake pipe 434 extending deep into the heat exchange drum 435 is provided with multiple circles of exhaust holes. The fixing clip 437 is fixedly connected to the inner wall of the fixing housing 410 and clamps the heat exchange drum 435 to fix it. The exhaust pipe 436 is arranged at the top end of the heat exchange drum 435 to discharge saturated steam. All parts of the steam generator 430 are made of materials resistant to high temperature and high pressure.

[0018] As shown Figure 3 in the figure, the fixing housing 410 includes a connecting part 411 and a housing part 412. The connecting part 411 is arranged at the frame of the fixing housing 410 and is an integral structure with the fixing housing 410. The connecting part 411 is in an overall right-angled structure, and one side is attached to the protective housing 1. The surface attached to the protective housing 1 is provided with through holes to fixedly connect the fixing housing 410 to the inner wall of the protective housing 1 through special screws. The housing part 412 is in an overall funnel shape that is wider at the top and narrower at the bottom, with a hollow structure inside. The bottom is designed with an opening above the water receiving tray 420 and is smaller than the size of the water receiving tray 420. The top end of the inner wall is designed with an upwardly concave arc, such a design enables the condensed water to quickly flow into the water receiving tray 420. The two opposite sides of the housing part 412 facing the wind are designed with louvers, and the fan blades on both sides are in a fixed inclined design, and the inclined directions are all towards the inside of the fixing housing 410. The generated steam is easily blocked and turned into condensed water and flows into the water receiving tray 420. The louver design allows air to flow into the fixing housing 410 more evenly, facilitating heating and humidification.

[0019] As shown Figure 4As shown in the figure, the water receiving tray 420 includes a water receiving tray body 421, a fixed base 422, and a drain pipe 423. The water receiving tray body 421 is a hollow rectangular parallelepiped structure with an open top, and its width is greater than the widest part at the top of the fixed housing 410. The fixed base 422 is a right prism structure distributed on both sides of the water receiving tray 420. The right prism is provided with through holes and is fixed to the inner wall of the protection housing 1 by special screws. The right-angled end of the right prism abuts against the right-angled corner formed by the water receiving tray 420 and the inner wall of the protection housing 1.

[0020] As Figure 5 As shown in the figure, the heat exchange coil section 3 includes a support plate 310 and heat exchange tubes 320. One support plate 310 is installed on each side of the heat exchange tubes 320. The support plate 310 is fixed to the inner wall of the protection housing 1 to fix the heat exchange tubes 320 installed between the support plates 310. The multiple heat exchange tubes 320 are connected in series to form a circuit and are parallel to each other. The water inlet and outlet of the circuit are fixed at the support plate 310 and communicate with the protection housing 1 to facilitate drainage and water inlet. The circuit formed by the heat exchange tubes 320 is vertically distributed between the support plates 310, and the heat exchange tubes 320 connected to the upper and lower ends of the support plate 310 are more than those connected to the middle circuit. Since more heat exchange tubes 320 have a higher heat exchange capacity, the number of heat exchange tubes 320 at the upper and lower ends of the support plate 310 is increased to make the overall heat exchange of the heat exchange coil section 3 uniform.

[0021] Principle of solving the problem: After the blower 5 is powered on and operates near the air outlet of the machine body, negative pressure air is generated and attracted to enter from the air inlet. After the air is attracted into the air conditioner body, it first passes through the filter section 2. The bag filter at the filter section 2 intercepts dust and other impurities in the air. Then, the filtered air enters the heat exchange coil section 3. Warm water flows through the heat exchange tubes 320 at the heat exchange coil section 3 to preheat the passing air, reducing the amount of condensed water generated by the contact of the supercooled air with the subsequent steam. After the pre-treated air enters the heating and humidifying section 4, the electric heater 433 on the inner wall of the steam barrel 432 continuously heats the water in the steam barrel 432 to generate superheated steam. The generated superheated steam enters the heat exchange barrel 435 through the inlet pipe 434. The superheated steam discharged from the exhaust holes on the surface of the inlet pipe 434 exchanges heat with the water in the heat exchange barrel 435 to become saturated steam. The generated saturated steam is discharged through the outlet pipe 436 into the solid housing 410 to heat and humidify the passing air. The entire heating and humidifying section 4 integrates the heating section and the humidifying section of the traditional air conditioning unit, making the overall volume smaller and the installation simpler. The air only needs to pass through one device, the heating and humidifying section 4, and can be transferred to the room through the air outlet faster.

[0022] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
