Description

Technical Field

[0001] This utility model relates to a filter replacement mechanism for an air-conditioning type range hood. Background Technology

[0002] Existing technologies disclose various air-conditioning-style range hoods, which add an air conditioning component to a range hood platform, thus achieving both the functions of a range hood and an air conditioner. The air conditioning component includes an indoor unit module and an outdoor unit module. The indoor unit module includes an evaporator and an indoor fan, while the outdoor unit module includes a condenser and an outdoor fan. A compressor is connected to the condenser and evaporator via refrigerant piping, and cooling and heating functions are achieved through a four-way valve. The air-conditioning-style range hood has an evaporator chamber where the evaporator is placed, and a filter is placed above the evaporator to filter particulate matter and other harmful substances brought in by the indoor unit's air intake. The filter's filtering capacity decreases after a period of use, therefore the air-conditioning-style range hood reminds the user to replace the filter after a set usage time. However, due to the lack of user training, installing the filter presents some difficulty. The filter is installed approximately 2 meters above the ground, posing a safety hazard during replacement, and frequent filter replacements result in a poor user experience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a filter replacement mechanism for an air-conditioning range hood that can automatically replace the filter, in light of the above-mentioned existing technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a filter replacement mechanism for an air-conditioning type range hood, characterized in that: it includes an evaporator cavity for accommodating an evaporator, a spare filter cavity for accommodating a spare filter, and a waste filter collection cavity for accommodating a waste filter. The spare filter cavity and the waste filter collection cavity are respectively located on both sides of the evaporator cavity. It also includes a conveying mechanism. Along the airflow direction, a working filter is provided at the filter installation position upstream of the evaporator. The conveying mechanism can transport the working filter to the waste filter collection cavity and transport the spare filter in the spare filter cavity to the filter installation position to become a working filter.

[0005] In order to enable the conveying mechanism to smoothly move the filter screen, the conveying mechanism is a conveyor belt. The rear half of the conveyor belt is located in the spare filter screen cavity, and the front half of the conveyor belt is located above the evaporator cavity. The spare filter screen is placed in the rear half of the conveyor belt, the working filter screen is placed in the front half of the conveyor belt, and the waste filter screen collection cavity is located in front of the conveyor belt.

[0006] Preferably, the conveyor belt is arranged horizontally, and correspondingly, the working filter and the spare filter are arranged horizontally.

[0007] Further optimized, the filter installation position is equipped with telescopic valves on both the front and rear sides, capable of vertical extension and retraction. Under normal operating conditions, the telescopic valves extend downwards to confine the working filter within the valve's position. During filter replacement, the telescopic valves rise upwards, allowing the working filter to enter the waste filter collection chamber, while a spare filter is transported to the filter installation position. This configuration, through the coordination of the telescopic valves and the conveyor belt, ensures reliable confinement of the working filter under normal operating conditions and guarantees smooth movement of the filter by the conveyor belt during filter replacement.

[0008] To prevent airflow between different chambers, under normal operating conditions, the telescopic valve extends downwards and abuts against the conveyor belt, thus isolating the evaporator chamber, the spare filter chamber, and the waste filter collection chamber from each other.

[0009] In order to allow airflow to flow smoothly through the working filter and the evaporator cavity, the upper part of the working filter is the indoor unit air inlet, and the side of the evaporator cavity is equipped with an indoor unit fan. The indoor unit air inlet is connected to the air inlet of the indoor unit fan through the evaporator cavity.

[0010] To reduce the impact of wind resistance on the conveyor belt, the width of the working filter is greater than the width of the conveyor belt.

[0011] To facilitate the removal and placement of the filter screen, both the spare filter screen cavity and the waste filter screen collection cavity are equipped with filter screen removal and placement ports.

[0012] To facilitate the smooth falling of the working filter into the waste filter collection chamber, the bottom of the waste filter collection chamber is lower than the bottom of the spare filter chamber.

[0013] To ensure that all the spare filters stored in the spare filter chamber can be moved to the waste filter collection chamber after use, the waste filter collection chamber can hold a greater number of filters than the spare filter chamber can hold.

[0014] Compared with the prior art, the advantages of this utility model are as follows: The filter replacement mechanism of this air-conditioning range hood places a spare filter in the spare filter chamber, a working filter above the evaporator chamber, and a waste filter in the waste filter collection chamber. When the working filter needs to be replaced, it is transported to the waste filter collection chamber by the conveying mechanism and collected as a waste filter. At the same time, the spare filter in the spare filter chamber is transported to the top of the evaporator chamber for use as a working filter, realizing automatic filter replacement. Users do not need to manually replace the filter regularly, which greatly improves the user experience. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the filter replacement mechanism according to an embodiment of the present invention;

[0016] Figure 2 for Figure 1 A partial schematic diagram of the filter replacement mechanism shown. Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 and Figure 2 As shown, the filter replacement mechanism of the air-conditioning range hood in this embodiment includes components such as an evaporator cavity 1, a spare filter cavity 2, a waste filter collection cavity 3, a conveying mechanism, and a telescopic valve 5.

[0019] The evaporator chamber 1 houses the evaporator 9, the spare filter chamber 2 houses the spare filter 6, and the waste filter collection chamber 3 houses the waste filter 8. Figure 1 The direction indicated by the middle arrow A is forward. The spare filter chamber 2 is located at the rear of the evaporator chamber 1, and the waste filter collection chamber 3 is located at the front of the evaporator chamber 1. In this embodiment, the conveying mechanism is a conveyor belt 4, which is arranged horizontally. The rear half of the conveyor belt 4 is located inside the spare filter chamber 2, and the spare filter 6 is horizontally stacked on the rear half of the conveyor belt 4. The front half of the conveyor belt 4 is located above the evaporator chamber 1, and the front half of the conveyor belt 4 is the filter installation position. The working filter 7 is horizontally placed on the front half of the conveyor belt 4, and the width of the working filter 7 is greater than the width of the conveyor belt 4. The waste filter collection chamber 3 is located at the front of the conveyor belt 4.

[0020] The evaporator 9 is located below the working filter 7, which is located at the top of the evaporator cavity 1. Above the working filter 7 is the indoor unit air inlet 11. An indoor unit fan 10 is installed on the side of the evaporator cavity 1. The indoor unit air inlet 11 is connected to the air inlet of the indoor unit fan 10 through the evaporator cavity 1. That is, along the air flow direction, the evaporator 9 is located downstream of the working filter 7.

[0021] The front and rear sides of the filter installation position are equipped with telescopic valves 5 that can extend and retract vertically. Under normal working conditions, the telescopic valves 5 extend downward to limit the working filter 7 between the telescopic valves 5. Furthermore, the telescopic valves 5 extend downward and abut against the conveyor belt 4, thereby isolating the evaporator cavity 1, the spare filter cavity 2, and the waste filter collection cavity 3 from each other and preventing cross-ventilation between the cavities.

[0022] For easy access to and from the filter screen, both the spare filter screen chamber 2 and the waste filter screen collection chamber 3 are equipped with filter screen access ports. Furthermore, the bottom of the waste filter screen collection chamber 3 is lower than the bottom of the spare filter screen chamber 2 to ensure that the working filter screen 7 on the filter screen mounting position can fall smoothly into the waste filter screen collection chamber 3. The waste filter screen collection chamber 3 can hold a greater number of filter screens than the spare filter screen chamber 2, ensuring that the waste filter screen collection chamber 4 has sufficient capacity.

[0023] After the air-conditioning range hood has been running for a certain period of time, such as 500 hours, the filter needs to be replaced. When replacing it, the telescopic valves 5 on both sides of the working filter 7 rise up, and the conveyor belt 4 rotates forward. The conveyor belt 4 transports the working filter 7 to the waste filter collection chamber 3 to become the waste filter 8. At the same time, the spare filter 6 at the bottom of the spare filter chamber 2 is transported to the filter installation position to become the working filter 7. After the replacement is completed, the conveyor belt 4 stops rotating.
