[0002] A water evaporation type air-conditioning fan (hereinafter referred to as an air-conditioning fan) is an energy-saving cooling product. Its principle is that a water evaporation carrier is installed at the air inlet of the body, a water tank is arranged at the lower end of the body, a water pump is placed in the water tank, and the water pump pumps the water in the water tank to the lower water trough to spray on the water evaporation carrier, making the water evaporation carrier wet. The fan runs at high speed, generating negative pressure inside the body, driving the outside air of the body to be inhaled from the air inlet of the body, passing through the water evaporation carrier, vaporizing water at normal temperature, and the water evaporation absorbs the vaporization heat to cool the water and the air. The unvaporized water flows back to the water tank for recycling, and the cooled air is blown out through the air duct and the air outlet, directly giving people a feeling of coolness. Since it does not use a compressor but uses an ordinary fan, it has low energy consumption and low cost, and is deeply favored by consumers in the hot summer. However, the air-conditioning fan is a single seasonal product, only suitable for use in the hot summer, and is idle for a long time during the year, resulting in a certain amount of time waste and resource waste.

[0016] A. In the warm and cold air blower provided by the present invention, an air duct is arranged outside the blower assembly, and an adjustable air duct structure is sleeved outside the air duct. The adjustable air duct is driven by a driving mechanism to rotate forward and backward relative to the air duct, so that the radial air inlet II on the adjustable air duct and the radial air inlet I on the air duct overlap or stagger. When the radial air inlet I and the radial air inlet II completely overlap, air will enter from the corresponding air inlets on the side shell I, side shell II and rear shell at the same time, and the maximum air volume will be obtained at the air outlet; when the radial air inlet II and the radial air inlet I on the air duct are in a staggered state, the radial air inlet will stop, and only the air entering from the axial air inlet on the rear shell is relied on, and the air outlet air volume is small. The structural principle and manufacturing process of controlling the air inlet of the present invention are simple, easy to install and produce, and the manufacturing cost is low.

[0017] B. The warm and cold air conditioner fan of the present invention can obtain a variety of air supply modes. When the warm air conditioner fan mode is turned on, the radial air inlet I and the radial air inlet II can be controlled to stagger, so that the air inlet direction is only axial, and the air enters from the back of the air duct, with high heating efficiency and warmer air outlet; when in the cold air conditioner fan mode, the radial air inlet I and the radial air inlet II are controlled to partially overlap or completely overlap, so that the air inlet direction is radial and axial, and the air enters from the periphery of the air duct and the rear shell, with smoother air inlet, large air volume and low noise.

[0018] C. When the warm and cold air conditioner fan of the present invention is in the warm air conditioner fan mode, the water evaporation carrier assembly can be controlled to work or not work; in a humid environment, the water evaporation carrier assembly does not work, which can reduce the indoor humidity; in a dry environment, the water evaporation carrier assembly works, which can increase the indoor humidity; by controlling the water evaporation carrier assembly to work or not work, the user can have a more comfortable indoor temperature and humidity environment.

[0019] D. The warm and cold air conditioner fan of the present invention can achieve multiple functions in one machine. It can be used for heating in winter, cooling in summer, humidifying when the air is dry, and dehumidifying when the air is humid. It saves the user the cost of purchasing multiple products, and the storage also occupies less space than multiple products, saving storage space. Description of the Drawings

The water tank 3 is located below the water receiving tray 36 and is connected to the water outlet II 36.3 on the water receiving tray 36. A water evaporation carrier I 23 is provided inside the rear shell 11, and a water storage cavity 7.2 is provided on the top cover 7. The water outlet I 7.1 on the water storage cavity 7.2 corresponds to and communicates with the upper end of the water evaporation carrier I 23. A water pump assembly 37 is provided in the water tank 3, including a water pump and a pumping pipeline. The water pump is installed in the water tank 3 and is connected to the water inlet 7.3 on the water storage cavity 7.2 through the pumping pipeline. A grille-shaped air outlet is provided on the front shell 1, an axial air inlet 11.1 is provided on the rear shell 11, and air inlets I 5.1 and II 8.1 are provided on the side shell I 5 and the side shell II 8 respectively. For details, see Figure 4As shown, of course, the air inlet can also be provided only on the side shell I or the side shell II; a heating element 26, a fan assembly, an air duct 27, an adjustable air duct 32, and a driving mechanism are also provided in the hollow cavity a. The heating element 26 can be a common heating wire heating element or a PTC heating element on the market, which generates heat to heat the air; the heating element 26 is located in front of or behind the fan assembly, and the fan assembly is located in the air duct 27. The fan assembly here includes a blade bundle 24, a fan blade 25, and a motor III 33. The motor III 33 is installed on the rear shell 11, the fan blade 25 is installed on the main shaft of the motor III, and the blade bundle 24 is a plastic part with a nut or a nut structure. Its function is to fix the fan blade 25. The fan blade 25 is arranged behind the blade bundle 24 and can be made of plastic or metal. Its function is to generate negative pressure when rotating, so that air can enter the inside of the fan body from the outside for air circulation. The motor III 33 is arranged behind the heating element 26 and is a common shaded pole motor, capacitor motor or DC motor on the market. The air duct 27 has openings at both ends, and its axis is arranged along the direction of the axial air inlet 11.1 to the air outlet 1a. The rear end of the air duct 27 is installed on the front shell 1 through fasteners such as bolts, or can also be installed on the rear shell 11. A plurality of radial air inlets I 27.1 are provided on the air duct 27. Its material is preferably a high-temperature resistant engineering plastic. The radial air inlet I 27.1 serves as an air inlet from the side, and the opening at the rear end of the air duct 27 serves as a wind gathering function. The air duct 27 is arranged outside the fan blade 25. In order to achieve a better wind gathering effect, the air duct 27 is preferably a stepped cylindrical structure. The adjustable air duct 32 has openings at both ends. It is sleeved on the outer cylindrical surface of the air duct 27. It is preferably a hollow cylindrical structure, and the material is a high-temperature resistant engineering plastic. A plurality of radial air inlets II 32.1 are provided on its cylindrical surface. The opening sizes of the radial air inlet I 27.1 and the radial air inlet II 32.1 can be kept the same, and the number of openings is the same. The adjustable air duct 32 has a rotation function relative to the air duct 27, and the relative rotation position of the adjustable air duct 32 relative to the air duct 27 can be adjusted by setting a manual structure or a driving mechanism, such as Figure 10 and Figure 11 shown; the driving mechanism includes a motor I 29, a gear 30, and a rack 28. The gear 30 is connected to the driving shaft of the motor I 29. The rack 28 is arc-shaped and is fixedly connected to the adjustable air duct 32. The gear 30 meshes with the rack 28. When the motor I 29 drives the gear 30 to rotate, the gear 30 drives the rack 28 and the adjustable air duct 32 to rotate, so as to effectively control the radial air intake volume entering the air duct 27 from the adjustable air duct 32. When the radial air inlet II on the adjustable air duct corresponds completely to the radial air inlet I on the air duct, the air intake volume of the air duct will be the largest. When the radial air inlet I and the radial air inlet II are completely staggered, the air duct 27 serves as a closed channel and only allows air to enter from the axial air inlet of the rear shell.

[0065] such as Figure 10 、Figure 11 and Figure 12 As shown in Figure 11 and Figure 12 , the rack 28 is arranged behind the air duct 27. It is an arc-shaped plate structure with teeth, made of engineering plastic, and functions to drive the adjustable air duct 21 to rotate. The motor I 29 is arranged behind the gear 30. It is a common synchronous motor or stepper motor on the market, and it functions to provide rotational force. The gear 30 is arranged behind the rack 28, and it functions to transmit the rotational force and drive the rack 28 to rotate. The motor cover 31 is arranged behind the motor I 29. It is a semi-circular cover structure and functions to protect and fix the motor I 29. The adjustable air duct 32 in the present invention itself has the functions of air intake, air concentration, and controlling the air intake area, and can well control the air volume entering the air duct 27 from both sides and the rear side.

The water evaporation carrier I 23, the water evaporation carrier II 35, and the water evaporation carrier III 34 surround both sides and the rear end of the air duct 27. The upper ends of the water evaporation carrier I 23, the water evaporation carrier II 35, and the water evaporation carrier III 34 respectively correspond to the water outlet I 7.1. The water flowing out from the water outlet I is sprayed on the three water evaporation carriers to wet the water evaporation carriers. The water receiving tray 36 is arranged below the water evaporation carrier I 23, the water evaporation carrier II 35, and the water evaporation carrier III 34. The excess water will flow into the water tank 3 from the water outlet II 36.3 of the water receiving tray 36.

The upper end of the water storage cavity 7.2 is open and corresponds one-to-one with the upper ends of the water evaporation carrier I 23, the water evaporation carrier II 35, and the water evaporation carrier III 34. The bottom of the water storage cavity 7.2 is provided with a plurality of drain outlets I 7.1 and a water inlet 7.3 connected to the water pump assembly 37. The drain outlet 7.1 is used to let the water added by the user flow down to the water evaporation carrier and finally into the water tank 3. The water storage cavity 7.2 is used to store water. The water inlet 7.3 is connected to the water pump assembly 37, and the water pumped up by the water pump assembly 37 flows into the water storage cavity 7.2 through this port. At the same time, a movable upper cover 6 is provided at the upper end opening of the water storage cavity 7.2. When the water storage cavity 7.2 is filled with water, the upper opening of the water storage cavity 7.2 is covered by the upper cover 6. The upper cover 6 is arranged above the front shell 1 and is a plate-shaped structure made of engineering plastic. Its function is to decorate and prevent the water pumped up by the water pump assembly 37 from splashing out.

[0072] As Figure 4As shown, the side case I5 and the side case II8 respectively form a hollow mounting groove I5.2 and a mounting groove II8.2 towards the inside.

The water passing port III11.5 at the upper end of the rear case is for water to pass through from above.

[0075] As a further preferred embodiment of the present invention, the side case I5, the side case II8 and the rear case 11 can also be made into an integral body to form a U-shaped shell structure. The air inlets I5.1, II8.1 and the axial air inlet 11.1 on it are combined to form an annular air inlet, and the water evaporation carrier I23, the water evaporation carrier II35 and the water evaporation carrier III34 form an integral body, that is, an annular water evaporation carrier. Placing the annular water evaporation carrier in the annular mounting groove of the U-shaped shell can also achieve the purpose of the present invention.

[0076] In addition, as Figure 4 shown, the front shell 1 is a hollow cavity structure with openings at both ends. A front net 21 is installed at the opening at the air inlet end of the front shell, and an air outlet adjustment grille that can change the air outlet direction is provided at the opening at the air outlet end of the front shell. The front net 21 is fixedly connected to the air outlet end of the air duct 27. Preferably, the front shell 1 includes a hollow circular cavity 1.1 on one side and a square cavity 1.2 on the other side. The front net 21 is installed at the position of the hollow circular cavity 1.1, and a horizontal blade 2 that can swing up and down and a vertical blade 18 that can swing left and right are installed at the position of the square cavity 1.2.

[0077] The specific structure is described as follows:

[0078] The horizontal blade connecting rod I12 is arranged behind the horizontal blade 2, which is a straight rod with multiple rotating shafts and is made of engineering plastic. Each rotating shaft corresponds to a horizontal blade 2, and its function is to enable the horizontal blade 2 to swing up and down synchronously, which is a common structure in the market. The motor bracket I13 is arranged behind the horizontal blade 2, which is a flat plate structure and is made of engineering plastic, and its function is to fix the motor II14. The motor II14 is arranged below the motor bracket I13 and is a common stepping motor or synchronous motor in the market, and its function is to provide rotational force. The vertical blade connecting rod I15 is arranged above the motor bracket I13, which is a straight rod with a runway circular ring structure and is made of engineering plastic, and its function is to move left and right under the action of the cam 16 so that the vertical blade 18 can swing.

[0079] The cam 16 is set on the rotating shaft of the motor II14, and is made of engineering plastic. Its function is to provide the rotational force to the motor II14 to make it rotate, drive the vertical blade connecting rod I15 to move left and right, and then the vertical blade 18 connected to the vertical blade connecting rod I15 to swing synchronously, so as to switch the wind direction in the left and right directions. The horizontal blade connecting rod II17 is set on one side of the horizontal blade 2. It is a straight rod with a porous structure and is made of engineering plastic. Its function is to connect the horizontal blades 2 in series. The vertical blades 18 are set behind the horizontal blades 2. They are long sheet-like structures and are made of engineering plastic. There are 7 pieces or other numbers. Their function is to change the wind direction. The horizontal blade bracket I19 is set on one side of the horizontal blade 2. It is a sheet-like structure with a semicircular notch and is made of engineering plastic. Its function is to support the horizontal blade 2 on one side so that the horizontal blade 2 can maintain the spacing. The vertical blade connecting rod II20 is set on the vertical blade 18. It is a straight rod with a hollow structure and is made of engineering plastic. Its function is to fix the vertical blade so that the vertical blade 18 can maintain the spacing. The front screen 21 is set behind the vertical blades 18. It is a circular arc-shaped bar structure made of high-temperature resistant engineering plastics, with air outlets on it, which plays a role in air outlet and protection. The horizontal blade bracket II22 is set on the opposite side of the horizontal blade bracket I19. It is a sheet-like structure with semicircular notches and is made of engineering plastics. Its function is to support the horizontal blades on one side to keep the horizontal blades apart. Of course, it is also possible to set up an independent drive structure to enable each horizontal blade to automatically flip up and down, or to use other air outlet adjustment grille structures that can automatically or manually change the air outlet direction. I will not go into details here.

[0080] The present invention is provided with a fan for air circulation, a water evaporation component for water circulation, and an adjustable air duct component for changing the air inlet direction on the upper part of the whole machine; and a water pump component for pumping water and a water tank for storing water on the lower part.

[0081] like Figure 8 As shown, when using the cold air mode, the user can open the upper cover 6 and add water to the water storage chamber 7.2 of the top cover 7. The water flows through the water outlet 7.1 under the action of gravity to the water evaporation carrier I23, the water evaporation carrier II35, and the water evaporation carrier III34. After the water is evenly distributed on the water evaporation carrier, it continues to flow down to the water receiving box 36. After being collected by the water receiving chamber 36.1 of the water receiving box 36, it flows into the water tank through the water outlet II36.3. The fan assembly is working, the heating element is not working, and the fan assembly is working. The negative pressure generated will cause the wind to pass through the air inlet I5.1, the air inlet II8.1, and the axial air inlet 11.1, and then through the water evaporation carrier I23, the water evaporation carrier II35, and the water evaporation carrier III34. The air is humidified and enters the interior of the fuselage. At this time, the radial air inlet II32.1 of the adjustable air duct 32 coincides with the radial air inlet I27.1 of the air duct 27. The wind can enter the air duct 27 radially and axially, and then be blown out through the air outlet of the front shell. The wind is humidified by water and can be used to cool the human body and humidify the room.

[0082] As shown Figure 9 in the figure, when the hot air mode is used, the user does not need to add water. The fan assembly works, the heating element works, and the motor I29 works to drive the gear 30 to rotate. The gear 30 then drives the rack 28 to rotate, and the gear 30 further drives the adjustable air duct 32 to rotate. The radial air inlet II32.1 of the adjustable air duct 32 is offset from the radial air inlet I27.1 of the air duct 27. The air inlet mode is the same as that of the cold air mode, but there is no water on the water evaporation carrier, and the air will not be humidified. At this time, the air can only enter the air duct 27 from the axial air inlet 11.1, and after being heated by the heating element 26, it is blown out from the front net 21. The air is heated by the heating element, and the air is warm and can be used for heating and indoor drying. See Figure 9

[0083] When the hot air humidification mode is used, the user adds water. The fan assembly works, the heating element works, and the motor I29 works to drive the gear 30 to rotate. The gear 30 then drives the rack 28 to rotate, and the gear 30 further drives the adjustable air duct 32 to rotate. The radial air inlet II32.1 of the adjustable air duct 32 is offset from the radial air inlet I27.1 of the air duct 27. The air inlet mode is the same as that of the cold air mode, and the air will be humidified. At this time, the humidified air enters the air duct 27 from the axial air inlet 11.1 in the radial direction, and after being heated by the heating element 26, it is blown out from the front net 21. The air is humidified by water and heated by the heating element 26. The air is warm and humid, and can be used for heating, humidifying, and is not likely to cause dry skin of people.

[0084] The present invention is provided with a total of three air inlets on the two side shells and the rear shell, and a water evaporation carrier is arranged at each air inlet, while an air outlet is arranged on the front shell. A wind channel is arranged inside the fan body, and an adjustable wind channel is arranged outside the wind channel. A heating element is arranged in the wind channel, and a fan assembly is arranged in front of or behind the heating element. The fan assembly can be inside the wind channel or not. A casing is arranged outside the adjustable wind channel, and a stepper motor is arranged behind the wind channel. The opening and closing of the air inlets in the radial direction are realized by controlling the adjustable wind channel through the stepper motor. When it is necessary to use it as a warm air air conditioner fan, the heating element works, and the water evaporation carrier works or does not work (it can humidify when working). The adjustable wind channel is adjusted to close the radial air inlets, and there is only one air inlet direction, which is to intake air from behind the heating element. The air passes through behind the heating element, and the fan rotates at a high speed, generating negative pressure inside the fuselage. This prompts the air outside the fuselage to be inhaled from the axial air inlet at the back, and heat exchange occurs between the heating element in the middle of the wind channel. After the cold air becomes hot air, it is blown out from the air outlet on the front shell, which is suitable for indoor heating in cold winters. When it is necessary to use it as a cold air air conditioner fan, the heating element does not work, the water evaporation carrier works, and the adjustable wind channel is adjusted to open the radial air inlets. The air inlet direction is multi-directional, and the air enters the wind channel from the back and the circumference, and then is blown out from the air outlet on the front shell of the front, which is suitable for cooling and relieving heat in hot summers; at the same time, a horizontal and vertical blade assembly is arranged in front of the air outlet. When the horizontal and vertical blades swing, the direction of the air blown out up, down, left and right can be adjusted. The principle and structure of the present invention are simple, and it is convenient for users to operate. Compared with traditional air conditioner fans, an adjustable wind channel and a heating element assembly for adjusting the air inlet direction are arranged inside the fuselage, realizing the functions of cold and warm air, multi-functional in one machine, and reducing the procurement cost of consumers.
