Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, and in particular to an air source heat pump with automatic water replenishment and humidification. Background Technology

[0002] An air source heat pump is a highly efficient heat energy lifting and transfer device based on the reverse Carnot cycle principle. It can use a small amount of electricity as power to transfer low-temperature heat from the outdoor air to the indoor environment through a refrigerant, thereby providing heating to the indoor space.

[0003] When the indoor unit of an air source heat pump, also known as a hot air blower, is working, the hot air outlet continuously supplies hot air into the room, which will reduce the humidity of the indoor air and make people feel dry. Therefore, some air source hot air blowers have introduced a humidification unit to increase the humidity of the indoor air.

[0004] In traditional air source heat pumps with humidification functions, the humidification unit requires users to replenish clean water periodically. This necessitates removing the humidification unit from the air source heat pump, refilling it with water, and then reinstalling it. The disassembly, reassembly, and water replenishment process is cumbersome and often consumes a certain amount of the user's time. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an air source hot air blower with automatic water replenishment and humidification to solve the above problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides an air source hot air blower with automatic water replenishment and humidification, which includes a casing and a humidification unit.

[0008] The front shell of the housing has a panel mounting opening, and an air vent panel is covered on the panel mounting opening. The bottom of the air vent panel has a lower air outlet. A bottom bracket extending forward is fixed to the bottom of the housing, and a side bracket extending outward is fixed to the side shell of the housing. The humidification unit includes a water tank, an atomizer, a float valve, and a water replenishment tank. The atomizer is placed in the water tank, which is supported and fixed on the bottom bracket. The water tank has a water mist outlet for discharging water mist from in front of the lower air outlet. The float valve is fixed through one side of the water tank. The float valve has a water outlet at the lower part inside the water tank and a water inlet on the side of the float valve protruding outside the water tank. The water replenishment tank is supported and fixed on the side bracket, and the bottom of the water replenishment tank is connected to the water inlet of the float valve through a connecting pipe.

[0009] Preferably, the float valve includes a valve body tube, a stop plug, a hinge, a connecting rod, and a float. The stop plug slides against the inner wall of the valve body tube. The stop plug is connected to a linkage rod at one end of the connecting rod. The stop plug and the connecting rod can rotate through the hinge. The outlet is located at the lower part of the valve body tube, and the inlet is located on one side of the valve body tube. The float is connected to the other end of the connecting rod and is used to move the stop plug within the valve body tube via the connecting rod to close or allow the connection between the outlet and the inlet.

[0010] Preferably, the top of the water tank is provided with a water pipe interface, and the water pipe interface is provided with a screw cap to seal it.

[0011] Preferably, the water tank includes a tank body and a cover plate covering the tank body, and the cover plate has a hollowed-out side to form the water mist outlet.

[0012] Preferably, a splash guard extends from the side wall of the tank below the water mist outlet, and the splash guard is inclined downward.

[0013] Preferably, the bottom of the tank is recessed to form a pit, the atomizer is installed in the pit, and a mist pipe is connected above the atomizer to guide the water mist to the cover plate.

[0014] Preferably, the bottom of the cover plate is provided with a wire through hole, and the bottom of the body shell is provided with a clearance opening corresponding to the wire through hole. The body shell is equipped with a humidification electronic control unit.

[0015] The technical effects achieved by this utility model include:

[0016] The aforementioned air-source hot air blower with automatic water replenishment and humidification has a water tank for the humidification unit installed at the bottom of the unit casing. The atomizer converts the water in the tank into water mist, which is blown out from the front of the lower air outlet of the unit casing to humidify the hot air. By introducing a float valve and a water replenishment tank, when the water level in the tank drops, the float valve can automatically open to connect with the water replenishment tank to replenish water in the tank. This eliminates the tedious manual operation process of users removing the water tank to replenish water and then reinstalling it, thus improving the user experience.

[0017] The water tank is installed on the side shell, making it easy for users to observe the water level inside and add water at any time by opening the cap. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the drawings. The embodiments of this utility model shown in and described with reference to the drawings are merely exemplary, and this utility model is not limited to these embodiments.

[0028] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related are omitted.

[0029] like Figure 1 As shown, this embodiment of the invention provides an automatic water replenishment and humidification air source hot air blower, which includes a casing 1 and a humidification unit 2. Combined with... Figure 2As shown, a panel mounting opening 101 is provided on the front shell surface 1a of the fuselage 1, and an air vent panel 11 is provided on the panel mounting opening 101. A lower air outlet 110 is provided at the bottom end of the air vent panel 11. A bottom bracket 12 extending forward is fixed to the bottom of the fuselage 1, and a side bracket 13 extending outward is fixed to the side shell surface 1b of the fuselage 1.

[0030] Combination Figure 1 and Figure 3 As shown, the humidification unit 2 includes a water tank 21, an atomizer 22, a float valve 23, and a water supply tank 24. The atomizer 22 is placed inside the water tank 21, which is fixed on the bottom bracket 12. The water tank 21 is provided with a water mist outlet 210 for discharging water mist from in front of the lower air outlet 110. The float valve 23 is fixed through one side of the water tank 21. The lower part of the float valve 23 inside the water tank 21 has a water outlet 230a, and the side of the float valve 23 protruding outside the water tank 21 has a water inlet 230b. The water supply tank 24 is fixed on the side bracket 13, and the bottom end of the water supply tank 24 is connected to the water inlet 230b of the float valve 23 through a connecting pipe 241.

[0031] When the aforementioned air source hot air blower is working, the atomizer 22 consumes water from the water tank 21 and converts it into water mist. The water mist rises to the top of the water tank 21 and is emitted from the water mist outlet 210. The lower air outlet 110, located behind the water mist outlet 210, blows the water mist out. As the water in the water tank 21 is gradually consumed, the water level in the tank decreases. The float valve 23 in the water tank 21 opens the connection between the water outlet 230a and the water inlet 230b, allowing water from the high-level water replenishment tank 24 to be automatically supplied to the water tank 21 through the connecting pipe 241 and the float valve 23. When the water level in the tank rises again, the float valve 23 gradually closes, completing the automatic water replenishment of the humidification unit 2. This eliminates the need for the user to disassemble the water tank 21 of the humidification unit 2, making it more convenient to use.

[0032] Because in the prior art, after the humidification unit 2 is installed, it is not easy for the user to observe the remaining water level in the water tank 21. In particular, for the convenience of water supply, the air source hot air blower usually installs the humidification unit 2 near the bottom air outlet 110, which may often cause the water in the water tank 21 to dry up and become unusable without the user noticing in time. The water replenishment tank 24 provided in this embodiment is installed on the side shell 1b, which makes it easy to observe the water level. The water replenishment tank 24 can be made of a light-transmitting material.

[0033] Combination Figure 1 and Figure 4As shown, the float valve 23 includes a valve body tube 231, a stop plug 232, a hinge 233, a connecting rod 234, and a float 235. The stop plug 232 slides against the inner wall of the valve body tube 231. The stop plug 232 is connected to a linkage support rod 236 provided on one end of the connecting rod 234 and can be rotated through the hinge 233. The outlet 230a is located at the lower part of the valve body tube 231, and the inlet 230b is located on one side of the valve body tube 232. The float 235 is connected to the other end of the connecting rod 234 and is used to drive the stop plug 232 to move within the valve body tube 231 through the connecting rod 234, so as to close or allow the connection between the outlet 230a and the inlet 230b. When the water level in the tank 21 drops, the float 235 pulls the connecting rod 234 downward, thereby causing the stop plug to slide to the right in the valve body pipe 231 through the linkage rod 236, opening the outlet pipe 230a, allowing water from the inlet 230b to supply water to the tank 21 through the outlet pipe 230a; as the water level in the tank gradually rises, the float valve 235 will pull the connecting rod 234 upward, thereby causing the stop plug to slide to the left in the valve body pipe 231 through the linkage rod 236, closing the outlet pipe 230a and stopping the water supply.

[0034] After the water in the water tank 24 is used up, water can be poured directly into the water tank 24. In this embodiment, the top of the water tank 24 is provided with a water pipe interface, and the water pipe interface is provided with a screw cap 242 to seal it. Water can be directly supplied to the water tank 24 by connecting to the user's home faucet through a hose.

[0035] The water tank 21 has a box-shaped structure. The water tank 21 includes a tank body 211 and a cover plate 212 covering the tank body 211. One side of the cover plate 212 is hollowed out to form the water mist outlet 210.

[0036] The inner wall of the tank 211 has an inner edge that can support the cover plate 212, corresponding to the bottom of the water mist outlet 210. A splash guard 213 extends from the side wall of the tank 211 and is inclined downward. The splash guard 213 is set to prevent the bottom of the water mist outlet 210 from being completely exposed. The mist enters the water mist outlet 210 through the gap between the splash guard 213 and the cover plate 212, preventing the water in the tank 21 from splashing out due to shaking.

[0037] The bottom of the tank 211 is recessed to form a pit 2110. The atomizer 22 is installed in the pit 2110. The atomizer 22 is connected to the top of the atomizer 22 to guide the water mist to the cover plate 212. The atomizer 22 is installed in the pit 2110, which is lower than other areas of the bottom of the tank 211. That is, at the lowest point where the float 235 sinks, there is no water in other areas of the bottom of the tank 211. The atomizer 22 can still use the water in the pit 2110 to provide water mist, waiting for the float valve 235 to open to replenish water, ensuring that the water mist supply is uninterrupted and facilitating the orderly automatic water replenishment.

[0038] The bottom of the cover plate 212 is provided with a wire through hole 2120, and the bottom of the body shell 1 is provided with a clearance opening 102 corresponding to the wire through hole 2120. The body shell 1 houses a humidification electronic control unit. The atomizer 22 is electrically connected to the humidification electronic control unit through a wire 222 passing through the wire through hole 2120 of the cover plate 212 and the clearance opening 102 of the body shell 1. Waterproofing treatment is required after the wire 222 is inserted into the wire through hole 2120. Figure 3 The wavy line indicates that the extension of the wire 222 has been omitted. The front shell 1a of the body shell 1 is provided with a control panel 14 that is connected to the humidification electronic control unit. Thus, the user can control the operation of the atomizer 22 through the control panel 14 to select whether humidification is needed.
