[0026] In this way, the air outlet direction and flow rate of the second fresh air outlet can be further accurately controlled, thereby enhancing the mixing effect of the fresh air flow and the cold air flow and reducing energy consumption.

[0027] In some embodiments, the outlet area of the cold air outlet is larger than the outlet area of the second fresh air outlet.

[0062] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0063] Please refer to Figure 1 and Figure 2 As shown, an embodiment of the present application provides a kitchen air conditioner 10, which includes a main body 100 and an oil fume fan. The main body 100 has a casing 140, and the main body 100 has a smoke collecting chamber 130 and an oil fume channel connecting the smoke collecting chamber 130 and the outside. The oil fume fan is arranged in the smoke collecting chamber 130 or the oil fume channel, and the casing 140 is provided with an oil fume suction port 143 connected to the smoke collecting chamber 130. The oil fume suction port 143 is connected to the smoke collecting chamber 130. The oil fume fan is used to generate negative pressure to suck oil fume, so that the oil fume flows into the smoke collecting chamber 130 through the oil fume suction port 143 and is discharged into the room through the flue.

[0064] In addition, in some embodiments, the kitchen air conditioner 10 also includes a fresh air unit and a refrigeration unit. The main body 100 also has a fresh air channel 110 and a refrigeration channel. The fresh air unit is used to generate fresh air airflow, and the fresh air channel 110 is connected to the air outlet end of the fresh air unit. The refrigeration unit is used to generate cold air, and the refrigeration channel is connected to the air outlet end of the refrigeration unit. The casing 140 is respectively provided with a fresh air outlet and a cold air outlet 1412. The fresh air outlet is connected to the fresh air channel 110, and the cold air outlet 1412 is connected to the refrigeration channel. In this way, the fresh air airflow generated by the fresh air unit can be discharged from the fresh air outlet through the fresh air channel 110 to the environment to improve the indoor air quality, and the cold air generated by the refrigeration unit is blown out from the cold air outlet 1412 through the refrigeration channel to lower the indoor temperature, thereby improving the indoor temperature comfort.

[0065] The fresh air outlet and the cold air outlet 1412 can be arranged above the oil fume suction port 143. In this way, when sucking oil fume, the fresh air outlet can deliver fresh air to the room, and the cold air outlet 1412 can deliver cold air to the room, thereby improving the indoor air quality and comfort.

[0066] However, the fresh air flow blown out from the fresh air outlet is clean room temperature air outdoors, while the temperature of the cold air flow blown out from the cold air outlet 1412 is lower. Therefore, there is a large temperature difference between the fresh air flow and the cold air flow. In this way, when the refrigeration unit and the fresh air unit are both in the on state, the cool air flow in the air is mixed with the fresh air flow at room temperature, which will make the user feel uncomfortable and thus affect the user's experience.

[0067] In view of the above problems, the kitchen air conditioner 10 provided in the embodiment of the present application, please refer to Figure 1 、 Figure 3 and Figure 4 As shown, a mixed air area 141 is provided on the casing 140, and the fresh air outlet includes a first fresh air outlet 142 and a second fresh air outlet 1411, and the first fresh air outlet 142 and the second fresh air outlet 1411 are respectively connected to the fresh air channel 110, wherein the second fresh air outlet 1411 and the cold air outlet 1412 are arranged in the mixed air area 141. In this way, the fresh air flow blown out through the second fresh air outlet 1411 and the cold air flow blown out through the cold air outlet 1412 are mixed in the mixed air area 141 and then discharged into the environment. In this way, the temperature difference between the fresh air flow and the cold air flow can be reduced, and the temperature of the fresh air flow can be lowered by the cold air to improve the uniformity of the air flow temperature in the blown air, thereby improving the indoor air quality and comfort, avoiding the problem of user discomfort caused by the large temperature difference between the fresh air flow and the cold air flow, and thus improving the user experience.

[0068] In some embodiments, the mixed air area 141, the first fresh air outlet 142 and the oil fume suction port 143 are arranged in sequence from top to bottom on the casing 140. In this way, the functional areas are clearly separated, avoiding interference between airflows, thereby improving air processing efficiency.

[0069] like Figure 1 and Figure 2 As shown in, in some embodiments, the casing 140 includes a first shell 140a, a second shell 140b and a third shell 140c. For example, the second shell 140b is arranged in a horizontal direction. Along the front-to-back direction of the main body 100, the first shell 140a is located above the second shell 140b and is connected to the front side of the second shell 140b, and the third shell 140c is located below the second shell 140b and is connected to the rear side of the second shell 140b. In this way, the first shell 140a and the third shell 140c are staggered in the front-to-back direction, the mixed air area 141 is arranged on the first shell 140a, the first fresh air outlet 142 is arranged on the second shell 140b, and the oil fume suction port 143 is arranged on the third shell 140c. In this way, the oil fume suction port 143, the mixed air area 141 and the first fresh air outlet 142 are clearly separated, avoiding interference between airflows, thereby improving air processing efficiency.

[0070] In addition, by arranging the air mixing area 141 above the oil fume suction port 143 , the coverage area of the air mixing area 141 can be increased, thereby improving the air treatment efficiency.

[0071] Please refer to Figure 1 、 Figure 3 and Figure 4 As shown, the mixed air area 141 extends along the width direction on the first shell 140a. Along the extension direction of the mixed air area 141, the second fresh air outlet 1411 and the cold air outlet 1412 are arranged side by side, and the outlet direction of the second fresh air outlet 1411 is toward the cold air outlet 1412. In this way, the fresh air flow blown out by the second fresh air outlet 1411 is first fully mixed with the cold air, and then discharged into the environment through the mixed air area 141, thereby improving the uniformity of the air flow temperature and then improving the air comfort.

[0072] Please continue to refer to Figure 1 、 Figure 3 and Figure 4 As shown, the second fresh air outlet 1411 is arranged at a position near the end of one end of the mixed air area 141, and the cold air outlet 1412 is arranged on a side close to the second fresh air outlet 1411. In this way, the air outlet direction of the second fresh air outlet 1411 is toward the cold air outlet 1412, which can increase the mixing area of the fresh air flow blown out by the second fresh air outlet 1411 and the cold air flow in the mixed air area 141, thereby facilitating the full mixing of the fresh air flow and the cold air in the mixed air area 141, so as to improve the uniformity of the air flow temperature blown out from the mixed air area 141, thereby improving the user's comfort experience.

[0073] In some embodiments, the kitchen air conditioner 10 also includes a wind shield 200, which is movably arranged at the second fresh air outlet 1411. The wind shield 200 is configured to change the air outlet direction of the second fresh air outlet 1411. In this way, the air outlet direction of the second fresh air outlet 1411 is adjusted by the wind shield 200, so that the fresh air flow blown out from the second fresh air outlet 1411 is quickly mixed with the cold air, thereby improving the user's comfort experience.

[0074] For example, Figure 5 and Figure 6As shown, the windshield member 200 includes a windshield ring 210, a windshield end cover 220 and a drive motor 230; the windshield ring 210 is fixedly arranged at the second fresh air outlet 1411, and the side wall of the windshield ring 210 facing the cold air outlet 1412 has a first air outlet 211 connected to the fresh air channel 110, the windshield end cover 220 is rotatably sleeved on the outer periphery of the windshield ring 210 and connected to the output shaft of the drive motor 230, and the side wall of the windshield end cover 220 has a second air outlet 2 21. The driving motor 230 is used to drive the wind shield end cover 220 to rotate relative to the wind shield ring 210 to open or close the second fresh air outlet 1411; when the wind shield end cover 220 rotates to the second air outlet 221 and is connected to the first air outlet 211, the fresh air flow is blown toward the cold air outlet 1412 through the first air outlet 211 and the second air outlet 221 in turn. In this way, the air outlet direction of the second fresh air outlet 1411 can be accurately controlled to meet different environments and usage requirements.

[0075] Among them, the cross-sectional profile of the wind shield ring 210 includes but is not limited to a circle, and the cross-sectional profile of the wind shield end cover 220 matches the cross-sectional profile of the wind shield ring 210. When the wind shield ring 210 is inserted into the wind shield end cover 220, the gap between the wind shield ring 210 and the wind shield end cover 220 is as small as possible while ensuring that the wind shield ring 210 and the wind shield end cover 220 rotate relative to each other, so as to prevent the fresh air flow from leaking from the gap between the wind shield ring 210 and the wind shield end cover 220; exemplarily, a sealing ring can be provided between the wind shield ring 210 and the wind shield end cover 220, so that when the wind shield ring 210 and the wind shield end cover 220 can rotate relative to each other, the sealing ring is used to seal the gap between the wind shield ring 210 and the wind shield end cover 220 to prevent the fresh air flow from leaking from the gap between the wind shield ring 210 and the wind shield end cover 220.

[0076] It can be seen that the wind shield 200 adopts a knob-shaped structure, which can cause the air outlet direction to be toward the cold air outlet 1412 by rotation, so that the fresh air flow and the cold air flow are mixed and cooled before being blown to the user, thereby improving the comfort of the air flow; in addition, the wind shield 200 adopts a knob-shaped method to control the flow rate of the fresh air flow, thereby improving the mixing effect of the fresh air flow and the cold air flow, and reducing the energy consumption of the equipment.

[0077] Please refer to Figure 7 As shown, the ratio of the circumferential opening width of the second air outlet 221 to the circumferential length of the wind shield ring 210 is 1:4 to 1:3. In this way, the air outlet direction and flow rate of the second fresh air outlet 1411 can be further accurately controlled, thereby enhancing the mixing effect of the fresh air flow and the cold air flow and reducing energy consumption.

[0078] In addition, if Figure 1 、 Figure 3 and Figure 4 As shown, the outlet area of the cold air outlet 1412 is larger than the outlet area of the second fresh air outlet 1411. In this way, the ambient temperature can be quickly adjusted and the air flow efficiency can be improved.

[0079] Exemplarily, the ratio of the air outlet area of the mixed air region 141 to the total air outlet area of the second fresh air outlet 1411 and the cold air outlet 1412 is 2:1 to 3:1. In this way, the air flow distribution and air processing efficiency are optimized, thereby improving the user's comfort experience and reducing energy consumption.

[0080] In order to further improve the mixing effect and efficiency of the fresh air flow and the cold air flow in the air mixing area 141, in the embodiment of the present application, please refer to Figure 3 As shown, the cold air outlet 1412 has an air guide structure 300, and the air guide structure 300 is configured to guide the cold air flow blown out of the cold air outlet 1412 at least toward one side of the second fresh air outlet 1411. In this way, the outlet of the fresh air flow is toward the cold air outlet 1412, and the cold air outlet 1412 is provided with the air guide structure 300 so that the cold air flow blown out of the cold air outlet 1412 is at least toward one side of the second fresh air outlet 1411, so that in the mixed air area 141, the fresh air flow and the cold air flow flow in a direction close to each other, thereby further accelerating the mixing efficiency and effect of the fresh air flow and the cold air flow.

[0081] For example, Figure 3 As shown in , the air guide structure 300 is an air guide slope or an air guide arc surface inclined toward the outer peripheral side of the cold air outlet 1412. In this way, the air guide structure 300 has a simple structure, is easy to implement, and has low cost while meeting the air guide effect.

[0082] Please continue to refer to Figure 1 、 Figure 3 and Figure 4 As shown, the mixed air area 141 is provided with a first air guide plate 400, and the top of the first air guide plate 400 is rotatably connected to the first shell 140a so that the first air guide plate 400 at least opens or closes the cold air outlet 1412; when an air guide angle is formed between the first air guide plate 400 and the first shell 140a, the first air guide plate 400 is configured to guide the mixed air flow blown out of the mixed air area 141 downward, so that the gas formed by the mixture of the fresh air flow and the cold air flow can be accurately guided, thereby improving the uniformity of air conditioning.

[0083] Exemplarily, the first air guide plate 400 is rotatably connected to the first shell 140a via a rotating shaft. In this way, the first air guide plate 400 can close or open the mixed air area 141 by rotating relative to the first shell 140a. When the mixed air area 141 is in a non-working state, it can prevent oil smoke, water vapor, etc. from entering the fresh air channel 110 and the cold air channel 120 through the second fresh air outlet 1411 and the cold air outlet 1412 respectively, and adhering to the wall surfaces of the fresh air channel 110 and the cold air channel 120 to produce odor. In this way, the odor will be blown into the room with the subsequent fresh air airflow and cold air airflow and affect the user experience. Therefore, by setting the first air guide plate 400, when the mixed air area 141 is in a non-working state, the first air guide plate 400 closes the mixed air area 141, thereby improving the cleanliness of the inner wall surfaces of the fresh air channel 110 and the cold air channel 120.

[0084] In some embodiments, please refer to Figure 1 and Figure 2 As shown, a second air guide plate 600 is movably provided at the oil fume suction port 143. For example, the top of the second air guide plate 600 is rotatably connected to the third shell 140c, so that the oil fume suction port 143 can be closed or opened by rotating the second air guide plate 600; when cooking, the second air guide plate 600 opens the oil fume suction port 143, and a guide angle is formed between the second air guide plate 600 and the third shell 140c, so that the oil fume is guided to the oil fume suction port 143 through the second air guide plate 600, so as to improve the efficiency of extracting oil fume.

[0085] Under ideal conditions, when a guide angle is formed between the second air guide plate 600 and the third shell 140c, there is no gap between the upper end surface of the second air guide plate 600 and the third shell 140c, thereby preventing part of the oil smoke from flowing outward between the top end surface of the second air guide plate 600 and the third shell 140c when the oil smoke is extracted.

[0086] However, there may be installation errors when assembling the second air guide plate 600 and the third shell 140c, which may result in a gap being formed between the upper end surface of the second air guide plate 600 and the surface of the third shell 140c when a guide angle is formed between the second air guide plate 600 and the third shell 140c. In this way, when extracting oil smoke, part of the oil smoke airflow will overflow outward into the environment through the gap, thereby causing a technical problem of poor air quality in the kitchen.

[0087] Based on the above problems, the kitchen air conditioner 10 provided in the embodiment of the present application, when a guide angle is formed between the second air guide plate 600 and the third shell 140c, an installation gap 700 is set between the top end surface of the second air guide plate 600 and the surface of the third shell 140c, that is, a installation gap 700 with a certain width is deliberately set between the top end surface of the second air guide plate 600 and the surface of the third shell 140c. In addition, a first fresh air outlet 142 is provided on the second shell 140b. When the oil fume suction port 143 sucks oil fume, the air outlet direction of the first fresh air outlet 142 is at least toward the third shell 140c, and the fresh air flow blown toward the third shell 140c flows from top to bottom along the plate surface of the third shell 140c. In this way, when the fresh air flow blown out from the first fresh air outlet 142 flows through the installation gap 700, the fresh air flow and the oil fume flow form a collision at the installation gap 700 (such as Figure 2 ), thereby suppressing the overflow of oil smoke into the environment, thereby improving the air quality and enhancing the user experience; and forming an installation gap 700 between the second air guide plate 600 and the third shell 140c, compared with the requirement of no installation gap 700 in the ideal state, reducing the installation difficulty and installation cost.

[0088] Thus, in the embodiment of the present application, first, when the second air guide plate 600 forms a guide angle with the third shell 140c on the main body 100, an installation gap 700 is provided between the top end surface of the second air guide plate 600 and the surface of the third shell 140c. Secondly, the fresh air flow from the first fresh air outlet 142 is at least partially guided to the third shell 140c, so that the fresh air flow blown to the third shell 140c flows from top to bottom along the surface of the third shell 140c and the air guide plate, and flows through the installation gap 700. The flow direction of the fresh air flow at the installation gap 700 is opposite to the overflow direction of the oil fume flow at the installation gap 700. In this way, the oil fume flow can be suppressed from overflowing outward from the installation gap 700 through the principle of mutual offset between the fresh air flow and the oil fume flow. That is, the fresh air flow is equivalent to forming a wind curtain protection layer at the installation gap 700 to block the oil fume flow, thereby improving the effect of suppressing the diffusion of oil fume; in addition, it can also reduce the installation difficulty between the second air guide plate 600 and the third shell 140c, thereby reducing the installation cost.

[0089] It can be understood that by setting the first fresh air outlet 142 between the mixed air area 141 and the oil fume suction port 143, the fresh air flow blown out by the first fresh air outlet 142 can be offset against the oil fume flow at the installation gap 700 to suppress the oil fume from overflowing outwards. At the same time, the distance between the first fresh air outlet 142 and the installation gap 700 is shortened, thereby ensuring that the fresh air flow blown out by the first fresh air outlet 142 has a certain strength to ensure the offsetting effect with the oil fume flow, thereby ensuring the effect of suppressing the overflow of oil fume; in addition, by setting the first fresh air outlet 142 separately, there is no need to divert part of the air flow in the mixed air area 141 to the installation gap 700, thereby improving the mixed air flow blown out of the mixed air area 141, thereby improving the indoor air quality and comfort, thereby improving the user experience.

[0090] In order to ensure that the fresh air flow suppresses the overflow of oil smoke at the installation gap 700, the flow rate of the fresh air flow blown out from the first fresh air outlet is greater than the speed of the rising oil smoke at the installation gap, and the suction force and flow rate at the oil smoke suction port are not equal to the suction force and flow rate at the installation gap 700, so as to further improve the reliability and stability of the air curtain protective layer formed at the installation gap 700, thereby further improving the effect of suppressing the spread of oil smoke.

[0091] Please continue to refer to Figure 2 As shown, the fresh air flow from the plate surface of the third shell 140c to the second air guide plate 600, under the suction force of the smoke, the fresh air flow will flow along the outer plate surface of the air guide plate (for example Figure 2 The upper surface of the second air guide plate 600 in the embodiment of the present invention) to the inner plate surface of the second air guide plate 600 (such as Figure 2 The fresh air flows along the lower surface of the second air guide plate 600 in the oil smoke chamber 130 and is sucked into the smoke collecting chamber 130 through the oil smoke suction port 143. In this way, the fresh air flow flowing along the surface of the second air guide plate 600 can form an air flow protection layer on the surface of the second air guide plate 600 to prevent the oil smoke from adhering to the surface of the second air guide plate 600, thereby improving the cleanliness of the second air guide plate 600.

[0092] It can be seen that the kitchen air conditioner 10 provided in the embodiment of the present application can not only suppress the oil smoke from overflowing outward from the installation gap 700 between the second air guide plate 600 and the third shell 140c, but also form an airflow protection layer to improve the situation where the oil smoke adheres to the surface of the second air guide plate 600, thereby enhancing the user experience.

[0093] Exemplarily, the width of the installation gap 700 is 1 mm to 10 mm. For example, when a guide angle is formed between the second air guide plate 600 and the third shell 140c, the installation gap 700 between the top end surface of the second air guide plate 600 and the surface of the third shell 140c is 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc., to ensure that the intensity of the fresh air flow at the installation gap 700 is greater than the intensity of the oil fume flow at the installation gap 700, and can form a counter-attack with the oil fume flow at the installation gap 700 to suppress the diffusion of oil fume, thereby improving the effect of suppressing the diffusion of oil fume.

[0094] Therefore, in the embodiment of the present application, the width dimension of the installation gap 700 includes but is not limited to 1mm to 10mm. As long as the fresh air flow forms a counter-flow with the oil smoke flow at the installation gap 700 and can suppress the oil smoke from overflowing outward from the installation gap 700, no specific restrictions are made here.

[0095] It should be noted that the width of the installation gap 700 refers to the width of the installation gap 700. Figure 2 The size of the middle installation gap 700 in the front-to-back direction.

[0096] Please continue to refer to Figure 1 and Figure 2 As shown, the kitchen air conditioner 10 also includes a guide plate 500, which is movably arranged at the first fresh air outlet 142, and the guide plate 500 is configured to adjust the air outlet direction of the first fresh air outlet 142; when the oil fume suction port 143 sucks oil fume, the guide plate 500 guides the air outlet direction of the first fresh air outlet 142 to form an inclined angle with the first shell 140a, so as to guide the fresh air flow at the first fresh air outlet 142 through the guide plate 500, thereby improving the accuracy of the flow direction of the fresh air flow at the first fresh air outlet 142, so that the fresh air flow blown out by the first fresh air outlet 142 flows from top to bottom along the surface of the third shell 140c to the second air guide plate 600, and flows along the plate surface of the second air guide plate 600, so as to suppress the oil fume from overflowing outward, and improve the oil fume adhering to the surface of the air guide plate, thereby improving the user experience.

[0097] Illustratively, the contour shape of the guide plate 500 matches the contour shape of the first fresh air outlet 142, so that the guide plate 500 can open or close the first fresh air outlet 142. When the guide plate 500 closes the first fresh air outlet 142, it can prevent oil smoke, water vapor, etc. from entering the fresh air duct 110 and adhering to the wall surface of the fresh air duct 110 to produce odor. When the fresh air unit is started and the guide plate 500 opens the first fresh air outlet 142, the odor in the fresh air duct 110 will be blown out together with the fresh air flow, thereby affecting the user's experience; in addition, since the blown fresh air flow is mixed with oil smoke, water vapor, etc. that flow back into the fresh air duct 110, the cleanliness of the fresh air flow blown to the second air guide plate 600 is poor, and thus a clean air flow protection layer cannot be formed to protect the plate surface of the second air guide plate 600, further affecting the user's experience.

[0098] When the guide plate 500 is in the open state and when in the non-cooking state, the fresh air flow blown out from the first fresh air outlet 142 only purifies the indoor environment, the fresh air flow can be guided toward the front side of the third shell 140c (for example, the side facing the user) through the guide plate 500 to quickly replace the indoor air with clean outdoor air, thereby improving the indoor air quality and enhancing the user experience.

[0099] In some embodiments, the guide plate 500 is arranged at the first fresh air outlet 142 and is rotatably connected to the second shell 140b. When the guide plate 500 rotates relative to the second shell 140b, the air outlet direction of the first fresh air outlet 142 is changed. In this way, the air outlet direction of the fresh air flow of the first fresh air outlet 142 is changed by rotating the guide plate 500 relative to the second shell 140b. The structure is simple, easy to implement, and low in cost.

[0100] Exemplarily, the guide plate 500 can be rotatably connected to the second shell 140b via a rotating shaft so that the guide plate 500 can rotate relative to the second shell 140b, thereby allowing the guide plate 500 to open or close the first fresh air outlet 142 by rotating, thereby meeting different needs.

[0101] In some embodiments, the kitchen air conditioner 10 also includes a first driving mechanism, which is connected to the guide plate 500. The first driving mechanism is configured to drive the guide plate 500 to move relative to the second shell 140b to adjust the air outlet direction of the first fresh air outlet 142. In this way, the guide plate 500 is driven by the first driving mechanism to rotate relative to the second shell 140b to automatically adjust the air outlet direction of the fresh air airflow from the first fresh air outlet 142, thereby improving the accuracy of the air outlet direction and the intelligence of the kitchen air conditioner 10.

[0102] Exemplarily, the first drive mechanism includes a first drive motor, and the output shaft of the first drive motor can be directly connected to the guide plate 500 to drive the guide plate 500 to rotate relative to the second shell 140b; in addition, the first drive mechanism can also include a transmission gear set, which is connected between the output shaft of the first drive motor and the guide plate 500 to change the speed and direction of the output shaft of the first drive motor through the transmission gear set, so that the guide plate 500 rotates according to a preset speed and rotation direction, thereby improving the accuracy of guiding the fresh air flow.

[0103] In addition, the first driving mechanism can also drive the guide plate 500 to swing back and forth in the front and rear directions. In this way, when not cooking, if the indoor air quality is poor, the guide plate 500 is in a reciprocating swinging motion mode, which can increase the coverage of the fresh air flow, thereby quickly replacing the indoor air with clean outdoor air and improving the air purification efficiency.

[0104] In some embodiments, the kitchen air conditioner 10 also includes a second driving mechanism, which is connected to the second air guide plate 600. The second driving mechanism is configured to drive the second air guide plate 600 to rotate relative to the third shell 140c so that the second air guide plate 600 closes or opens the oil fume suction port 143. By driving the second air guide plate 600 to rotate relative to the third shell 140c through the second driving mechanism, the intelligence of the kitchen air conditioner 10 is further improved.

[0105] Exemplarily, the second drive mechanism includes a second drive motor, and the output shaft of the second drive motor can be directly connected to the second air guide plate 600 to drive the second air guide plate 600 to rotate relative to the third shell 140c; in addition, the second drive mechanism can also include a transmission gear set, which is connected between the output shaft of the second drive motor and the second air guide plate 600 to change the speed and direction of the output shaft of the second drive motor through the transmission gear set, so that the second air guide plate 600 rotates according to a preset speed and rotation direction, thereby improving the guidance accuracy of the oil fume airflow.

[0106] Of course, the second air guide plate 600 can also be rotated manually or mechanically to open or close the oil fume suction port 143 .

[0107] The kitchen air conditioner 10 also includes a third drive mechanism, which is connected to the first air guide plate 400. The third drive mechanism is configured to drive the first air guide plate 400 to rotate relative to the first shell 140a so that the first air guide plate 400 closes or opens the mixed air area 141. By driving the first air guide plate 400 to rotate relative to the first shell 140a through the third drive mechanism, the intelligence of the kitchen air conditioner 10 is further improved.

[0108] In summary, in the embodiment of the present application, a mixed air area is set up, which includes a second fresh air outlet and a cold air outlet. In this way, the fresh air flow blown out by the second fresh air outlet and the cold air blown out by the cold air outlet are mixed in the mixed air area and then discharged into the environment, so as to reduce the temperature difference between the fresh air flow and the cold air flow, thereby improving the indoor air quality and comfort, avoiding the problem of user discomfort caused by the large temperature difference between the fresh air flow and the cold air flow, and thus improving the user experience.
