The overhead air conditioning system of the elevator car means that after the air conditioning system directly places or hangs the air conditioning host on the outer side of the top of the elevator car, air in the elevator car is pumped out through an air inlet and an air inlet structure of the air conditioning host, and after the air conditioning host refrigerates (heats), the air is returned into the elevator car through an air outlet and an air supply structure, so that the aim of adjusting the air temperature in the elevator car is achieved.

In one embodiment, as shown in fig. 1 to 5, an elevator air conditioner 1 is provided, and the elevator air conditioner 1 may specifically include an air conditioner main unit 100, where the air conditioner main unit 100 includes a main unit housing 110 having a mounting cavity (not labeled in the drawings), a compressor 120, a condenser 130, an evaporator 140, and an electric tapping structure 150. Wherein, the two opposite sides of the installation cavity in the first direction are respectively provided with a condenser installation area (not labeled in the figure) and an evaporator installation area (not labeled in the figure), the condenser 130 is installed in the condenser installation area, the evaporator 140 is installed in the evaporator installation area, the compressor 120 is installed between the condenser 130 and the evaporator 140, and the compressor 120 is respectively connected with the condenser 130 and the evaporator 140. The condensed water formed in the evaporator seating area may flow to the condenser seating area through the bottom wall 111 of the installation cavity, the condenser seating area is further installed with the electric tapping structure 150, and the tapping part of the electric tapping structure 150 is located below the condenser 130 to sputter the condensed water in the condenser seating area into the condenser 130 through the tapping part (not shown) of the electric tapping structure 150 so that the condensed water may be evaporated by the condenser 130.

It can be understood that, in the elevator air conditioner 1 according to the embodiment of the present application, the air conditioner host 100 can be directly placed or suspended on the outer side of the top of the elevator car, and the air in the elevator car is pumped out, cooled (heated) by the air conditioner host 100 and then sent back into the elevator car 2, so that the purpose of adjusting the air temperature in the elevator car is achieved. Taking the present elevator air conditioner 1 as an example, it mainly uses a refrigerant to cool air, the refrigerant is compressed into high-temperature and high-pressure gas by the compressor 120, and then the heat is emitted by the condenser 130 to become high-pressure liquid. Next, the high-pressure liquid is throttled down by an expansion valve to become a low-pressure liquid to be transferred to the evaporator 140. In the evaporator 140, the low-pressure liquid absorbs the heat of the air drawn back in the elevator car and evaporates, so that the temperature of the air is reduced and the air is returned to the elevator car 2, and the purpose of reducing the temperature in the elevator car is achieved. Finally, the refrigerant again enters the compressor 120, and circulates.

In addition, in order to realize the whole power supply operation of the air conditioner host 100, a power box 160 is further installed in the installation cavity, and the power box 160 is electrically connected with various electrical components (including but not limited to the compressor 120) in the air conditioner host 100.

In this way, in the embodiment of the present application, when the condensed water is generated in the air conditioning main unit 100, that is, when the condensed water is formed on the evaporator mounting area due to the operation of the evaporator 140, the condensed water flows to the condenser mounting area through the bottom wall 111 of the mounting cavity and is temporarily stored at the bottom of the condenser mounting area, at this time, the electric beating structure 150 is started, so that the condensed water in the condenser mounting area is sputtered into the condenser 130 through the beating part of the electric beating structure 150, so that the condensed water can be evaporated by the condenser 130, and the condensed water does not need to be directly discharged to the outside through a drain pipe as in the conventional household air conditioner, and meanwhile, the heat dissipation problem of the condenser 130 can be further solved by evaporating the condensed water through the condenser, thereby ensuring the stable operation of the condenser 130. Therefore, the technical scheme can effectively solve the problem of discharging condensed water in the elevator air conditioner 1.

In some examples, as shown in fig. 1, 2 and 3, the electric tapping structure 150 includes a tapping wheel 151 having a tapping portion and a tapping motor 152 driving the tapping wheel 151 to rotate, the tapping wheel 151 being disposed under the condenser 130 to tap condensed water in a condenser seating area under the driving of the tapping motor 152. Thus, through the above structure arrangement, the beating wheel 151 is driven to rotate by the water beating motor 152, so that the beating part of the beating wheel 151 continuously beats the condensed water in the condenser arrangement area in the rotation process, and the condensed water is continuously sputtered into the condenser 130, and finally the condensed water can be evaporated by the condenser 130.

In some examples, as shown in fig. 1, 2 and 3, the bottom wall 111 of the mounting cavity is disposed obliquely in the first direction such that a portion of the bottom wall 111 of the mounting cavity located in the condenser placement area is lower than a portion located in the evaporator placement area. In this way, by the above-described arrangement, it is better ensured that condensate water formed on the evaporator receiving area as a result of the operation of the evaporator 140 can flow completely through the bottom wall 111 of the installation space to the condenser receiving area. Further, the bottom wall 111 of the mounting cavity 111 is arranged in a structure with two high sides and a low middle in a second direction, and the second direction is perpendicular to the first direction. Thus, through the above structure, the condensed water on two sides of the bottom wall 111 of the installation cavity in the second direction can be collected better, and then flows from the bottom of the evaporator installation area to the bottom of the condenser installation area through the bottom wall 111 of the installation cavity, so that the condensed water is concentrated at the bottom of the condenser installation area.

In some examples, as shown in fig. 1, 2 and 3, a portion of the bottom wall 111 of the installation cavity located in the condenser installation area is convexly provided with a plurality of baffles 112, the tops of the plurality of baffles 112 are abutted against the bottom of the condenser 130, and the plurality of baffles 112 are arranged in a staggered manner in the first direction so as to form a labyrinth water storage tank at the bottom of the condenser 130. Therefore, through the structure, the evaporator placement area can temporarily store the condensed water through the labyrinth water storage tank, so that the condensed water is intensively treated at the bottom of the condenser placement area. Further, the beating part of the electric beating structure 150 is arranged in the labyrinth water storage tank to beat the condensed water in the labyrinth water storage tank, so, through the arrangement of the structure, the beating part of the electric beating structure 150 mainly performs condensed water beating operation in the labyrinth water storage tank, and the sputtered condensed water can only be sputtered onto the condenser 130 or onto the wall of the labyrinth water storage tank, so that the problem that the sputtered condensed water splashes with other components in the installation cavity is avoided. Furthermore, the air conditioner host 100 further comprises a water level detection switch (not shown) and an alarm module (not shown), wherein the water level detection switch is positioned in the labyrinth water storage tank, a water outlet (not shown) communicated to the outer side of the host housing 110 is formed in the side wall of the labyrinth water storage tank, and the water outlet is sealed by the leakage prevention plug.

It will be appreciated that the plurality of baffles 112 mentioned in the above example may be replaced by a first baffle having a middle opening and a second baffle according to actual needs, where the first baffle and the second baffle are both extended along the second direction, and the top of the first baffle abuts against the bottom of the condenser 130 to form a rectangular water storage tank having a middle opening in cooperation with the side wall of the installation cavity, the second baffle is disposed at a distance from the middle opening in the first direction, the second baffle is located outside the rectangular water storage tank, and the length of the second baffle in the second direction is greater than the length of the middle opening in the second direction, so as to block the middle opening in a staggered manner. At this time, the flapping part of the electric flapping structure 150 may be placed in the rectangular water storage tank to flap the condensed water in the rectangular water storage tank, i.e. the flapping part of the electric flapping structure 150 mainly performs the operation of flapping the condensed water in the rectangular water storage tank, and the sputtered condensed water can only be sputtered onto the condenser 130 or onto the wall of the rectangular water storage tank, so as to avoid the problem that the sputtered condensed water splashes with other components in the installation cavity. The above-mentioned water level detection switch can specifically detect the water level through a sensing piece arranged in the labyrinth water storage tank or the rectangular water storage tank and having a preset height, so that when the water level in the labyrinth water storage tank or the rectangular water storage tank reaches the preset height and contacts with the sensing piece, a corresponding control signal is output through the sensing piece, so that the air conditioner host 100 is controlled to stop, and meanwhile, the alarm module is controlled to give a corresponding prompt to a user. The alarm module can specifically give corresponding reminding to the user in a voice mode or a man-machine interface display mode or an audible and visual reminding mode.

In some examples, as shown in fig. 1, 3 and 5, the air conditioner host 100 further includes a first ventilation air duct 171 and a first air suction assembly 172, the first ventilation air duct 171 is installed in the condenser installation area, and the side wall of the installation cavity adjacent to the first ventilation air duct 171 in the first direction is provided with an air inlet and an air outlet of the first ventilation air duct 171 respectively. The first suction assembly 172 and the condenser 130 are both installed in the first ventilation air duct 171, and the condenser 130 is located between the first suction assembly 172 and the air inlet of the first ventilation air duct 171. Therefore, through the arrangement of the above structure, after the air in the hoistway is pumped into the first ventilation air duct 171, the air needs to pass through the condenser 130 first, so as to better bring the heat emitted by the condenser 130 in the first ventilation air duct 171 and the evaporated condensed water to the air outlet of the first ventilation air duct 171 completely, and then discharge the heat and the evaporated condensed water to the hoistway again.

It will be appreciated that the first suction assembly 172 described above may specifically employ a centrifugal fan to better draw air from the hoistway into the first ventilation duct 171. In order to better form the first ventilation air duct 171 and to accommodate and assemble the centrifugal fan, a first upper air duct body 1711 having an air outlet and an upper fan mounting groove and a first lower air duct body 1712 having a lower fan mounting groove may be provided, wherein the upper fan mounting groove is communicated with the air outlet, and when the first upper air duct body 1711 and the first lower air duct body 1712 are connected together, the upper fan mounting groove and the lower fan mounting groove form a complete fan mounting groove and the first ventilation air duct 171 to correspondingly accommodate and assemble the centrifugal fan.

In some examples, as shown in fig. 1, 3 and 4, the air conditioner host 100 further includes a second air ventilation duct 181 and a second air extraction component 182, the second air ventilation duct 181 is installed in the evaporator installation area, and the side wall of the installation cavity adjacent to the second air ventilation duct 181 in the first direction is provided with an air inlet and an air outlet of the second air ventilation duct 181 respectively. The second exhaust component 182 and the evaporator 140 are both installed in the second ventilation air duct 181, and the evaporator 140 is located between the second exhaust component 182 and the air inlet of the second ventilation air duct 181. Therefore, through the arrangement of the structure, after the air in the elevator car is pumped into the second air passage 181, the air is required to pass through the evaporator 140, and after being completely cooled by the evaporator 140, the air is brought to the air outlet of the second air passage 181 so as to be discharged into the elevator car again.

It will be appreciated that the second suction assembly 182 may be embodied as a centrifugal fan to better draw air from the elevator car into the second ventilation duct 181. In order to better form the second ventilation air duct 181 and to accommodate and assemble the centrifugal fan, a second upper air duct body 1811 having an air outlet and an upper fan mounting groove and a second lower air duct body 1812 having a lower fan mounting groove may be provided, wherein the upper fan mounting groove is communicated with the air outlet, and when the second upper air duct body 1811 and the second lower air duct body 1812 are connected together, the upper fan mounting groove and the lower fan mounting groove form a complete fan mounting groove and the second ventilation air duct 181 to correspondingly accommodate and assemble the centrifugal fan.

In some examples, as shown in fig. 1 and 2, the air inlet of the first ventilation air duct 171 and the air inlet of the second ventilation air duct 181 are both laid with the first filter screen 113. Thus, through the above-described structural arrangement, the air in the hoistway and the air in the elevator car can be prevented from bringing other impurities into the first ventilation air duct 171 and the second ventilation air duct 181. Further, in order to better dissipate heat of other components in the installation cavity, two opposite sides of the installation cavity in the second direction are respectively provided with a heat dissipation opening 114, and the heat dissipation opening 114 is paved with a second filter screen 115, wherein the second direction is perpendicular to the first direction. Thus, through the arrangement of the second filter screen 115, the air in the well can be effectively prevented from bringing impurities into the installation cavity.

In some examples, as shown in fig. 1, 2 and 3, the elevator air conditioner 1 further includes an elevator air conditioner air inlet structure 200 and an elevator air conditioner air supply structure 300, the air inlet of the second ventilation duct 181 is communicated with the car top air inlet of the elevator car through the elevator air conditioner air inlet structure 200, and the air outlet of the second ventilation duct 181 is communicated with the car top air outlet of the elevator car through the elevator air conditioner air supply structure 300. In this way, the air conditioner host 100 can pump out the air in the elevator car through the air inlet of the second ventilation air duct 181 and the air inlet structure 200 of the elevator air conditioner, and send the air back to the elevator car 2 through the air outlet of the second ventilation air duct 181 and the air inlet structure 300 of the elevator air conditioner after the air conditioner host 100 refrigerates (heats), so that the purpose of adjusting the air temperature in the elevator car is achieved.
