Description

Technical Field

[0001] The utility model relates to the technical field of fan devices, in particular to a temperature-regulating window-type fresh air fan device. Background Art

[0002] A thermostatic window ventilation unit combines air exchange and temperature regulation, typically installed in a window or wall opening. It's primarily used to improve indoor air quality while maintaining a comfortable temperature. The unit draws in fresh air from the outside and removes exhaust gases and pollutants. The unit typically features heating or cooling functions to adjust the indoor temperature for comfort throughout the seasons. Users can set their desired temperature to maintain a stable indoor environment, regardless of outside temperature fluctuations.

[0003] The air outlet of a window fan is usually provided with an adjustable louver group, and by adjusting the up and down inclination angles of the louvers, the fan can supply air to different upper and lower positions. The angle of the existing window fan booster nozzle cannot be adjusted, and the booster nozzle can only supply air in one direction. When the inclination angle of the louvers is too large, the wind ejected by the booster nozzle blows directly to the blade surface of the louver, so that the wind flow rate begins to decay due to resistance, and cannot be quickly discharged from the fan. At this time, the user can perceive a decrease in the air volume, and habitually increase the power of the fan, which leads to a lack of user experience and consideration of energy saving and efficiency improvement, and the fan cannot be used efficiently and fully utilized. Therefore, a temperature-controlled window fresh air fan device is proposed. Utility Model Content

When the inclination angle of the louver is too large, the wind ejected by the booster nozzle directly impacts the blade surface of the louver, causing the wind flow rate to begin to decay and cannot be quickly discharged from the fan, resulting in a reduction in the air volume that the user can perceive.

[0027] Example

[0028] Reference Figure 1-Figure 5 , is an embodiment of the present utility model, which provides a temperature-adjustable window-type fresh air blower device, comprising: a blower unit 100 and a regulating unit 200;

[0029] The fan unit 100 includes a housing 101 and an air duct 102 fixedly mounted on the inner wall of the housing 101. A composite filter 103 and an electric heater 104 are fixedly mounted on the inner wall of the housing 101 from left to right. The bottom of the air duct 102 is fixedly connected to a blower 105. One side of the housing 101 is fixedly connected to an air inlet louver group 106 via bolts. An evaporator 107 is fixedly mounted on the inner wall of the housing 101. A compressor 108 is fixedly mounted at the bottom of the inner cavity of the housing 101. A control panel 109 is fixedly mounted on one side of the housing 101. The fan unit 100 also includes a condensing assembly 110 for adjusting the air temperature.

[0030] The adjustment unit 200 includes an air supply louver group 201 fixedly connected to one side of the casing 101, and multiple pairs of fixed plates 202 are fixedly connected to one side of the air duct 102. A boost nozzle 203 is rotatably connected between each pair of fixed plates 202, and a metal hose 204 is fixedly connected to the air duct 102. The multiple boost nozzles 203 distributed vertically are staggered and fixedly connected to each other with multiple connecting ropes 205, and the multiple boost nozzles 203 distributed horizontally at the top are fixedly connected to a connecting plate 206. The adjustment unit 200 also includes a traction component 207 for pulling the air supply louver group 201 and the boost nozzle 203 for synchronous deflection.

[0031] Among them, the traction assembly 207 includes a pulley 2071 fixedly connected to the top of the inner cavity of the casing 101, and a traction rope 2072 is fixedly connected between the louver at the bottom of the air supply louver group 201 and the connecting plate 206. The traction rope 2072 passes through the pulley 2071 and contacts the pulley 2071. A turning handle 2073 is rotatably connected to one side of the casing 101. The turning handle 2073 passes through one side of the casing 101 and is fixedly connected to the louver at the bottom of the air supply louver group 201. A threaded rod 2074 is threaded through one side of the turning handle 2073, and a plurality of limiting holes that fit the threaded rod 2074 are opened on one side of the casing 101.

[0032] The inner cavity of the housing 101 is divided into three areas by three partitions of different sizes. The bottom partition forms a sealed space with the bottom of the housing 101, and the other two partitions are staggered and fixedly connected to the inner wall of the housing 101. When the air passes through the air inlet louver group 106, the air will pass through the two partitions at the top in sequence and enter the air duct 102. When the outdoor ambient temperature is lower than the indoor temperature at night, the blower 105 is started. The high-speed rotation of the internal impeller of the blower 105 generates positive air pressure and wind force, so that Air from the outside of the housing 101 is drawn into the housing 101 through the air inlet louver set 106, and then filtered by the composite filter 103. The composite filter 103 is provided with multiple layers of different types of filter materials. Among them, the primary efficiency layer captures larger particles, the intermediate efficiency layer captures smaller particles, and finally, the HEPA layer captures tiny particles and bacteria, ensuring that various pollutants in the air are effectively removed. The filtered air enters the blower 105, and the blower 105 delivers the air to the air duct 102;

[0033] Then the air in the air duct 102 is transported to the boost nozzle 203 through the metal hose 204. The end of the boost nozzle 203 is designed to be conical, so that the air in the air duct 102 is compressed and discharged from the air supply louver group 201. The air supply louver group 201 can adjust the up and down angles of the air blown by the fan, thereby achieving the purpose of constant oxygen temperature control. When the temperature difference between indoor and outdoor is small, the compressor 108 can be turned on for cooling or the electric heater 104 can be turned on for auxiliary temperature control. When the compressor 108 is cooling, the refrigerant in the compressor 108 absorbs heat in the evaporator 107 and turns into gas, lowering the ambient temperature. When heating, the refrigerant absorbs external heat, and the gas is compressed by the compressor 108 to increase the pressure and temperature. The evaporator 107 can remove heat from the cooled fluid, absorb a large amount of heat and output low temperature. The condensing component 110 cooperates with the evaporator 107 to cool the outdoor cold air and increase the outdoor temperature, thereby realizing heat exchange and temperature control between indoor and outdoor.

[0034] The electric heater 104 generates heat by heating a resistance wire with electric current. The control panel 109 allows the user to control the equipment in the housing 101 to adjust the fan temperature and operating mode. The composite filter 103, electric heater 104, blower 105, evaporator 107, compressor 108 and control panel 109 are all conventional means in the field of fan devices. The technology is very mature, and the working principle and connection relationship are not further described here.

[0035] When the air supply angle of the air supply louver group 201 needs to be adjusted, the threaded rod 2074 is rotated to disengage it from the limiting hole on one side of the housing 101, and the air supply louver group 201 is driven to deflect as a whole by rotating the handle 2073, so that the air supply louver group 201 can deflect up and down. In the process of the air supply louver group 201 deflecting upward, the louver blade at the bottom of the air supply louver group 201 will pull the traction rope 2072, so that the traction rope 2072 is on the pulley 2071. The traction rope 2072 slides, and the connecting plate 206 is pulled upward, so that the opening of the boost nozzle 203 is deflected upward. The multiple boost nozzles 203 distributed vertically are staggered and connected to each other through the connecting rope 205, so that the connecting plate 206 can drive all the boost nozzles 203 to deflect upward through the connecting rope 205. After the deflection, the threaded rod 2074 is rotated to insert it into the corresponding limiting hole to fix the direction of the air supply louver group 201 and the boost nozzle 203;

[0036] At this time, when the boost nozzle 203 sprays air, the air will pass through the gaps between the multiple louvers in the air supply louver group 201, so that the louvers will not cause too much obstruction to the air, and reduce the attenuation of the wind speed caused by the louvers, so that the user can intuitively feel the wind delivered by the fan from a physical sense, thereby improving the user experience. When the air supply louver group 201 needs to be deflected downward, the handle 2073 is rotated in the opposite direction to make the louvers of the air supply louver group 201 tilt downward as a whole. At this time, the traction rope 2072 will not pull the connecting plate 206, and the connecting plate 206 and the multiple boost nozzles 203 tilt downward by their own gravity to ensure that the boost nozzle 203 and the air supply louver group 201 are tilted downward at the same angle. After the adjustment is completed, the tilt angle is fixed by the threaded rod 2074.

[0037] In addition, the condensation component 110 includes a condenser 1101 fixedly mounted on the bottom of the inner wall of the casing 101, a condensation water pipe 1102 is fixedly connected to one side of the evaporator 107, a fan 1103 is fixedly mounted on one side of the condenser 1101, the air inlet louver group 106 is located on one side of the inner cavity of the casing 101 and is fixedly sleeved with filter cotton, a water receiving tray 111 is slidably provided on one side of the casing 101, the water receiving tray 111 is located below the condensation water pipe 1102, a floating plate 112 is slidably provided on the inner wall of the water receiving tray 111, and a transparent window 113 corresponding to the position of the floating plate 112 is inlaid on one side of the casing 101.

[0038] The air inlet louver group 106 can filter the air preliminarily while it is being taken in through the filter cotton to reduce the burden on the composite filter 103. The condenser 1101 is used for cooling. The high-temperature and high-pressure gas refrigerant flows from the compressor 108 into the condenser 1101. In the condenser 1101, the refrigerant gas releases heat to the external environment through the heat exchanger, thereby cooling. The fan 1103 is used to help the condenser 1101 take away the heat. A copper pipe that passes through the partition is fixedly connected between the evaporator 107 and the compressor 108. The copper pipe is responsible for transporting the refrigerant that has absorbed heat in the evaporator 107 and turned into gas to the compressor 108. The moisture generated by the operation of the evaporator 107 is discharged through the condensed water pipe 1102.

[0039] The condensation water pipe 1102 passes downward through the bottom partition, and the condensation water discharged from the condensation water pipe 1102 can be collected through the water receiving tray 111 to prevent the condensation water from wetting the interior of the casing 101. When the condensation water contacts the float plate 112, the float plate 112 floats up due to buoyancy. The user can observe the position of the float plate 112 through the transparent window 113 to remind the user of the water level in the water receiving tray 111. When the float plate 112 rises to the highest point, the water receiving tray 111 is taken out and the condensation water in the water receiving tray 111 is poured out to prevent the water in the water receiving tray 111 from overflowing in the casing 101.

[0040] Furthermore, a UV lamp 114 and a negative ion generator 115 are fixedly installed on the inner wall of the casing 101 from top to bottom. The UV lamp 114 and the negative ion generator 115 are both located on one side of the evaporator 107. Mounting grooves are provided on the top and bottom of the casing 101, and fixing clips 116 are provided on the inner sides of the two mounting grooves.

[0041] The UV lamp 114 and the negative ion generator 115 are both located on one side of the evaporator 107. The UV lamp 114 can emit ultraviolet rays to kill bacteria and viruses in the air. The negative ion generator 115 absorbs dust and other pollutants in the air by releasing negative ions, causing them to settle, thereby refreshing the air, thereby improving air cleanliness and user comfort. The composite filter 103, electric heater 104, blower 105, evaporator 107, compressor 108 and control panel 109 are all conventional means in the field of fan devices, and the technology is very mature. The fixing clip 116 is hidden and is used to fix the fan in a hidden position. It is also easy to maintain and replace. The above-mentioned UV lamp 114, negative ion generator 115 and fixing clip 116 are also conventional means in the field of fan devices, and the technology is very mature. No further elaboration is made on the working principle and connection relationship here.

[0042] During use, when it is necessary to adjust the air supply angle of the air supply louver group 201, the threaded rod 2074 is rotated to disengage it from the limiting hole on one side of the casing 101, and the air supply louver group 201 is driven to deflect as a whole by rotating the handle 2073. During the upward deflection of the air supply louver group 201, the louver blade at the bottom of the air supply louver group 201 will pull the traction rope 2072. At this time, the traction rope 2072 will pull the connecting plate 206 upward, so that the opening of the boost nozzle 203 as a whole deflects upward. After the deflection, the threaded rod 2074 is rotated to insert it into the corresponding limiting hole to fix the direction of the air supply louver group 201 and the boost nozzle 203.

[0043] When the air supply louver group 201 needs to be deflected downward, the handle 2073 is rotated in the opposite direction so that the louvers of the air supply louver group 201 are tilted downward as a whole. At this time, the traction rope 2072 will not pull the connecting plate 206, and the connecting plate 206 and the multiple boost nozzles 203 are tilted downward by their own gravity to ensure that the boost nozzles 203 and the air supply louver group 201 are tilted downward at the same angle. After the adjustment is completed, the tilt angle is fixed by the threaded rod 2074.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
