DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0027] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0028] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0029] See also Figures 1 to 4 As shown, according to an embodiment of the utility model, a kitchen air conditioner is provided, which has a drainage pipe, and the kitchen flue 1 has a first connecting port and a second connecting port, the end of the drainage pipe away from the kitchen air conditioner is connected to the flue 1 through the first connecting port, and the end of the range hood exhaust duct 2 away from the range hood is connected to the flue 1 through the second connecting port, and the position of the first connecting port is higher than the position of the second connecting port.

[0030] In this technical solution, the present application connects the drainage pipe of the kitchen air conditioner with the kitchen flue 1, and the connection point between the drainage pipe and the flue 1 is higher than the connection point between the range hood exhaust pipe 2 of the range hood and the flue 1. Since the hot air sucked by the range hood is always in a floating state in the flue 1, when the condensed water generated by the air conditioner is discharged into the flue through the drainage pipe, the condensed water with a downward trend is always evaporated and blown away by the hot air in the flue 1, and finally discharged along the flue 1 with the hot air, thereby solving the problem that the kitchen air conditioner discharges the condensed water to the outer wall through the drainage pipe, which will pollute the outer wall, and the problem that the kitchen pipe is connected to the sewer pipe of the vegetable washing basin to discharge the condensed water will be inconvenient. At the same time, there is also a solution in the prior art that uses a water wheel to beat the condensed water onto the condenser for evaporation to realize the discharge of condensed water. However, in the kitchen scenario, the condensed water generated by the indoor unit of the air conditioner will contain substances such as grease and organic carboxylic acid, which will bring certain risks of dirt, blockage and corrosion to the fins, copper pipes and other components of the outdoor unit of the air conditioner. The solution adopted by the present application of discharging condensed water into the flue 1 and evaporating and blowing away the condensed water by the hot air from the range hood to achieve condensed water discharge can also avoid the problem of condensed water causing certain dirt blockage and corrosion risks to the fins, copper tubes and other components of the air conditioner outdoor unit. Furthermore, since the condensed water does not pass through the range hood in the process of entering the flue, the condensed water will not corrode the range hood. Among them, the first connecting port and the second connecting port are respectively constructed on the side wall of the flue 1.

[0031] See also Figure 1 and Figure 2 As shown, as embodiment 1, the kitchen air conditioner includes a first unit, a second unit, a water pump 3 and a guide pipe 4, the first unit includes a water receiving tray 5, the second unit includes a fan 6 and an air conditioning exhaust pipe 7, the air conditioning exhaust pipe 7 is a drainage pipe, the water inlet of the water pump 3 is connected to the water receiving tray 5, the water outlet of the water pump 3 is connected to the inlet of the guide pipe 4, the outlet of the guide pipe 4 extends to the air inlet side of the fan 6, and the end of the air conditioning exhaust pipe 7 away from the flue 1 extends to the air outlet side of the fan 6.

[0032] In this embodiment, the water pump 3 pumps the condensed water collected in the water receiving pan 5 to the air inlet side of the fan 6 through the guide pipe 4. Under the high-speed rotation of the fan 6, the condensed water falling from the outlet of the guide pipe 4 is dispersed, and the blades of the fan 6 disperse the water droplets into water mist. The formed water mist enters the air conditioning exhaust pipe 7 from the air outlet side of the fan 6 under the action of wind, and then is discharged into the flue 1, thereby realizing a zero drainage design without the need to set up an additional condensed water drainage pipe in the kitchen. Among them, a water level detector 14 is also provided in the water receiving pan 5. When the water level detector 14 detects that the condensed water collected in the water receiving pan 5 reaches a preset height, the water pump 3 is turned on.

[0033] Specifically, as a derivative solution of the first embodiment, the kitchen air conditioner includes a first unit, a second unit and a guide pipe 4, the first unit includes a water collecting pan 5, the second unit includes a fan 6 and an air conditioning exhaust duct 7, the air conditioning exhaust duct 7 is a drainage pipe, the inlet of the guide pipe 4 is connected to the water collecting pan 5, the outlet of the guide pipe 4 extends to the air inlet side of the fan 6, the position of the water collecting pan 5 is higher than the position of the outlet of the guide pipe 4, and the end of the air conditioning exhaust duct 7 away from the flue 1 extends to the air outlet side of the fan 6.

[0034] In this technical solution, the water pump 3 is omitted, and only gravity is used to guide the condensed water in the water receiving tray 5 to the air inlet side of the fan 6 through the guide pipe 4, and then the blades of the fan 6 are used to break up the water droplets into water mist, and then the wind force of the fan 6 is used to make the water mist enter the air conditioning exhaust pipe 7, and then discharged into the flue 1. The fan 6 can be a centrifugal fan, see Figure 2 As shown, the centrifugal fan is placed flat in the second unit, the top of the centrifugal fan is its air inlet side, the right side of the centrifugal fan is its air outlet side, the second end of the guide tube 4 extends to the top of the centrifugal fan, and the condensed water flowing out of the guide tube 4 is broken into water mist by the blades of the centrifugal fan during the falling process. Of course, the fan 6 can also be an axial flow fan. When the fan 6 is an axial flow fan, its installation method and other related components can be adjusted accordingly, so that the condensed water flowing out of the guide tube 4 can also be broken into water mist.

[0035] As a specific implementation, a diverter plate is provided at the outlet of the flow guide tube 4 , and a plurality of water outlet holes are constructed on the diverter plate; or an atomizer is provided at the outlet of the flow guide tube 4 .

[0036] In this embodiment, the diverter plate is similar to the shower head. When the diverter plate is set at the outlet of the guide tube 4, since there are multiple water outlet holes on the diverter plate, the water flow out of the guide tube 4 will become multiple thinner water flows, so that the water flow is initially thinned before being dispersed by the fan 6, which is conducive to the water flow being dispersed into ultrafine water mist by the fan 6, and then conducive to the condensed water being evaporated and discharged in the flue. When an atomizer is set at the outlet of the guide tube 4, the water flow out of the guide tube 4 can be turned into mist in advance, and the mist water flow can be converted into nano-scale mist particles after being dispersed by the fan 6, which is conducive to the condensed water being evaporated and discharged in the flue. Among them, the atomizer can be an ultrasonic atomizer.

[0037] More specifically, a one-way valve is provided in the air conditioning exhaust duct 7, and its function is to exhaust the exhaust air of the fan 6 of the second unit only in one direction to the flue 1, and the smoke in the flue 1 cannot flow back into the kitchen air conditioner.

[0038] See also Figure 4 As shown, as a second embodiment, the kitchen air conditioner includes a first unit, a water pump 3 and a drainage pipe 8. The first unit includes a water receiving tray 5, the drainage pipe 8 is a drainage pipe, the water inlet of the water pump 3 is connected to the water receiving tray 5, and the water outlet of the water pump 3 is connected to an end of the drainage pipe 8 away from the flue 1.

[0039] In this embodiment, the water pump 3 directly discharges the condensed water collected in the water receiving tray 5 into the flue 1 through the drainage pipe 8, which is simpler than the solution of the first embodiment. When the drainage pipe 8 is a drainage pipe, a third connecting port can be constructed on the side wall of the flue 1, and the end of the drainage pipe 8 away from the air conditioner is connected to the flue 1 through the first connecting port, the end of the range hood exhaust pipe 2 away from the range hood is connected to the flue 1 through the second connecting port, and the end of the air conditioning exhaust pipe 7 away from the air conditioner is connected to the flue 1 through the third connecting port.

[0040] See also Figure 4 As shown, an atomizing device is provided at one end of the drainage pipe 8 away from the first unit. By providing the atomizing device, the water flow can be atomized into mist before entering the flue 1, which is conducive to the condensed water being evaporated and discharged in the flue 1. The atomizing device can be an ultrasonic atomizer or other forms of atomizers.

[0041] As a derivative solution of the second embodiment, the kitchen air conditioner includes a first unit and a drainage pipe 8. The first unit includes a water receiving tray 5. The drainage pipe 8 is a drainage pipe. One end of the drainage pipe 8 away from the flue 1 is connected to the water receiving tray 5. The position of the water receiving tray 5 is higher than the position of the first connecting port.

[0042] In this technical solution, the water pump 3 is omitted, and only gravity is used to discharge the condensed water in the water receiving tray 5 into the flue 1 through the drainage pipe 8. The design is simpler and the cost is reduced by omitting the water pump 3.

[0043] See also Figure 1 and Figure 4 As shown, an installation space is formed between the kitchen ceiling board 9 and the top of the kitchen, and the kitchen air conditioner is installed in the installation space.

[0044] In this technical solution, the space below the ceiling panel 9 is the kitchen space 19. When the air conditioner is installed in the installation space formed between the ceiling panel 9 and the top of the kitchen, it is equivalent to not being able to see the air conditioner in the kitchen space 19, which is more aesthetically pleasing. In addition, the installation position of the air conditioner is relatively high, which also facilitates the installation of its drainage pipe higher than the position of the range hood exhaust pipe 2 of the range hood. Among them, the first unit and the second unit are both fixed to the top (ceiling) of the kitchen through a plurality of suspension rods 17. The first connecting port and the second connecting port are both located on the side wall of the flue 1 in the installation space. The range hood exhaust pipe 2 passes through the ceiling panel 9 and is connected to the flue 1 through the second connecting port, that is, the range hood exhaust pipe 2 has a partial section blocked by the ceiling panel 9, which also has a certain aesthetic effect.

[0045] It should be noted that the first unit also includes a first shell 13, an evaporator 12 and an air outlet duct 15, the water receiving tray 5 is installed at the bottom of the first shell 13, the evaporator 12 is in the first shell 13, and is located above the water receiving tray 5. The first unit can be called an evaporation unit. The evaporator 12 is a three-stage structure, which includes a first section and a second section opposite to each other and a third section located between the first section and the second section. The evaporator 12 is arranged along the three side walls of the first shell 13. The water receiving tray 5 corresponds to the structure of the evaporator 12, and includes two side collecting parts and a main collecting part located between the two side collecting parts. The water pump 3 and the water level detector 14 are arranged in the middle area of ​​the main collecting part. Therefore, the middle area of ​​the main collecting part is relatively large. In order to facilitate the condensed water to be collected in the middle area of ​​the main collecting part, so that the water pump 3 can transport the condensed water away, it can be considered to make the positions of the two side collecting parts higher than the position of the main collecting part. Of course, the water pump 3 can also be installed in the second unit, and the water inlet of the water pump 3 only needs to be connected to the water receiving tray through a water pipe. The first housing 13 has two air outlets on one side wall where the evaporator 12 is not arranged. One end of the two air outlet ducts 15 is connected to the two air outlets respectively, and the other ends of the two air outlet ducts 15 are connected to the kitchen space 19. Therefore, the cold air during cooling by the air conditioner can be transported to the kitchen space 19 through the two air outlet ducts 15. The first housing 13 is composed of a bottom plate, four side panels and a top cover.

[0046] It should also be noted that the second unit also includes a second shell 18 and a condenser (not shown in the figure), and the condenser and the fan 6 are both installed in the second shell 18. The second unit can be called a condensing unit, so the airflow driven by the fan 6 eventually forms hot air, and the airflow discharged from the air conditioning exhaust duct 7 is hot air, so that the water mist can be heated in the air conditioning exhaust duct 7, which is more conducive to the water mist being evaporated and discharged in the flue 1. Among them, the second shell 18 is also composed of a chassis, four side panels and a top cover. It can be understood that the first unit and the second unit are connected by a refrigerant connecting pipe 16 to realize the circulation of the refrigerant between the first unit and the second unit.

[0047] See also Figure 1 and Figure 4 As shown, a return air vent 10 is constructed on the ceiling plate 9, and the air conditioner can return air through the return air vent 10. At the same time, a return air hole can be constructed on the wall between the ceiling plate 9 and the top of the kitchen for returning air. One end of the return air hole is connected to the installation space, and the other end of the return air hole is connected to the external space, which is equivalent to the air conditioner being able to introduce outdoor fresh air. For buildings with more complex designs, a return air duct 11 with a certain length can be inserted into the return air hole to extend it to the outdoors, so that it can be ensured that the return air in the air conditioner contains outdoor fresh air.

[0048] It is easy for those skilled in the art to understand that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred implementations of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
