[0003] In the related art, the kitchen air conditioner includes a casing, a refrigeration unit and a fresh air unit located inside the casing. The casing is provided with a fresh air outlet and a cold air outlet. The casing is also provided with a fresh air channel connecting the fresh air outlet and the fresh air unit, and a refrigeration channel connecting the cold air outlet and the refrigeration unit. The fresh air generated by the fresh air unit is blown from the fresh air outlet to the indoor room through the fresh air channel to purify the indoor air, and the cold air generated by the refrigeration unit is blown from the cold air outlet to the indoor room through the refrigeration channel to lower the indoor temperature, thereby achieving the purpose of cooling and cooling and improving the comfort of the indoor temperature. The cold air outlet is arranged close to the side of the fresh air outlet.

[0004] However, in the related art, the setting position of the cold air outlet is offset toward the fresh air outlet, resulting in uneven cold air blowing toward the user, thereby causing the user to feel uncomfortable. Summary of the Invention

[0010] In the kitchen air conditioner provided in the embodiment of the present application, a mixed air area and a first air guide plate are arranged on the main body, the mixed air area includes a first fresh air outlet and a cold air outlet arranged side by side along a first direction, and the cold air outlet and the first fresh air outlet are offset near one end of the mixed air area, the first fresh air outlet is connected with the fresh air channel, and the cold air outlet is connected with the refrigeration channel. The first air guide plate is arranged in the mixed air area, and a ring-shaped air outlet gap is formed between the peripheral wall of the first air guide plate and the mouth wall of the mixed air area. In this way, the fresh air airflow blown out through the first fresh air outlet and the cold air airflow blown out through the cold air outlet are first mixed in the mixed air area to form a mixed airflow, and then the mixed airflow formed in the mixed air area is evenly discharged circumferentially through the air outlet gap, thereby improving the uniformity of the cold air blown to the user, thereby improving the user's physical comfort.

[0011] In some embodiments, the top end of the first air guide plate is rotatably connected to the top of the air mixing area so that the first air guide plate rotates between a first state and a second state; when the first air guide plate rotates to the first state, an annular air outlet gap is formed between the peripheral wall of the first air guide plate and the outline of the air mixing area; when the first air guide plate rotates to the second state around the limited axis at its top, the first air guide plate opens the air mixing area, and an inclined angle is formed between the first air guide plate and the surface where the air mixing area is located.

[0017] In some embodiments, the kitchen air conditioner further comprises a second air guide plate, the second air guide plate being rotatably disposed at the oil fume suction port, the second air guide plate being configured to open or close the oil fume suction port;

[0018] The main body also has a second fresh air outlet, which is connected to the fresh air channel and is located between the oil fume suction port and the mixed air area.

[0019] In this way, when the fresh air flow blown out from the second fresh air outlet blows towards the surface of the second air guide plate, a wind curtain protective layer can be formed on the surface of the second air guide plate to prevent oil smoke from adhering to the surface of the second air guide plate.

[0020] In some embodiments, the kitchen air conditioner further includes a driving mechanism, which is respectively connected to the first air guide plate and the second air guide plate, and the driving mechanism is configured to synchronously drive the first air guide plate and the second air guide plate to rotate relative to the main body, so that the first air guide plate switches between the first state and the second state while the second air guide plate switches between opening and closing the oil fume suction port.

[0021] In this way, the first air guide plate and the second air guide plate are driven to move synchronously by the driving mechanism, which simplifies the operation steps, thereby allowing the first air guide plate and the second air guide plate to quickly switch between different states, thereby improving the switching efficiency.

[0022] In some embodiments, the body comprises a first shell, a second shell, and a third shell connected in sequence. Along the front-to-back direction of the body, the second shell is horizontally arranged, the first shell is located above the second shell and connected to the front side of the second shell; the third shell is located below the second shell and connected to the rear side of the second shell;

[0023] In this way, each functional area is clearly separated, avoiding interference between air flows and thus improving air handling efficiency.

[0024] In some embodiments, the air mixing area extends along the width direction on the first shell, and the air outlet direction of the first fresh air outlet is toward the cold air outlet.

[0025] In this way, the fresh air flow and the cold air are fully mixed, thereby improving the air comfort.

[0026] In some embodiments, the kitchen air conditioner further includes a wind shield, which is disposed at the first fresh air outlet and is configured to direct the air outlet direction of the first fresh air outlet toward the cold air outlet.

[0027] In this way, the air outlet direction of the first fresh air outlet is adjusted by the wind shield so that the fresh air flow blown out by the first fresh air outlet is quickly mixed with the cold air, thereby improving the user's comfort experience.

[0028] In some embodiments, the wind shield member includes a wind shield ring, a wind shield end cover and a drive motor; the wind shield ring is fixedly arranged at the first fresh air outlet, and the side wall of the wind shield ring facing the cold air outlet has a first air outlet connected to the fresh air channel, the wind shield end cover is rotatably sleeved on the outer periphery of the wind shield ring and connected to the output shaft of the drive motor, and the side wall of the wind shield end cover has a second air outlet, and the drive motor is used to drive the wind shield end cover to rotate relative to the wind shield ring to open or close the first fresh air outlet; when the wind shield end cover rotates to the second air outlet and is connected to the first air outlet, the fresh air flow is blown to the cold air outlet through the first air outlet and the second air outlet in sequence.

[0029] In this way, the air outlet direction of the first fresh air outlet can be accurately controlled to meet different environments and usage requirements.

[0030] In some embodiments, the ratio of the circumferential opening width of the second air outlet to the circumferential length of the wind shield ring is 1:4 to 1:3.

[0031] In this way, the air outlet direction and flow rate of the first fresh air outlet can be further accurately controlled, the mixing effect of the fresh air flow and the cold air flow can be enhanced, and energy consumption can be reduced.

[0032] In some embodiments, the outlet area of the cold air outlet is larger than the outlet area of the first fresh air outlet;

[0033] And / or, the ratio of the air outlet area of the mixed air area to the total air outlet area of the first fresh air outlet and the cold air outlet is 2:1 to 3:1.

[0034] In this way, the ambient temperature can be adjusted quickly and the air flow efficiency can be improved. In addition, the air flow distribution and air processing efficiency are optimized, thereby improving the user's comfort experience and reducing energy consumption.

[0036] In this way, the mixing efficiency of the fresh air flow and the cold air flow can be further accelerated.

[0037] In some embodiments, the air guide structure is an air guide slope or an air guide arc surface that is inclined toward the outer peripheral side of the cold air outlet.

[0071] 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.

[0072] Please refer to Figures 1 to 10 As shown, the kitchen air conditioner 10 provided in the embodiment of the present application is suitable for use in the kitchen. The kitchen air conditioner 10 includes a main body 100, a fume blower, a fresh air unit and a refrigeration unit. It can extract the fume in the kitchen, replace the air in the kitchen with clean fresh air from the outdoors, and cool the kitchen, etc., so as to improve the quality and comfort of the air in the kitchen, thereby improving the user experience.

[0073] Among them, the main body 100 is provided with a smoke collecting chamber 130, an oil smoke passage, a fresh air passage 110 and a refrigeration passage 120, and the oil smoke fan is arranged in the smoke collecting chamber 130 or the oil smoke passage. The main body 100 also has a shell, on which are respectively provided an oil smoke suction port 143, a fresh air outlet and a cold air outlet 1412. The oil smoke suction port 143 is communicated with the smoke collecting chamber 130, and the smoke collecting chamber 130 is communicated with the external air through the oil smoke passage. When cooking, the oil smoke fan is started to generate a negative pressure for sucking oil smoke, so that the oil smoke airflow in the kitchen can enter the smoke collecting chamber 130 through the oil smoke suction port 143 and be discharged through the oil smoke passage, thereby achieving the purpose of sucking oil smoke; in addition, the fresh air The air outlet is connected to the fresh air duct 110, and the fresh air duct 110 is connected to the air outlet end of the fresh air unit. When the fresh air unit starts working, the clean air outside is blown out through the fresh air outlet to improve the indoor air quality; and one end of the refrigeration channel 120 is connected to the cold air outlet 1412, and the other end is connected to the air outlet end of the refrigeration unit. In this way, the cold air generated by the refrigeration unit is blown out through the cold air outlet 1412 to cool the kitchen, thereby achieving the purpose of refrigeration; of course, the refrigeration unit can also heat. When the weather is cold in winter, the refrigeration unit can also heat, and the generated hot air is blown out through the cold air outlet 1412 to achieve the purpose of indoor heating.

[0074] Among them, the principle of the fume fan sucking out the fume, the principle of the fresh air unit generating the fresh air flow, and the principle of the refrigeration unit cooling and heating can all be referred to the relevant technology and will not be repeated here.

[0075] Among them, the fresh air flow blown out by the fresh air outlet is clean room temperature air outdoors, while the temperature of the cold air flow blown out by the cold air outlet 1412 is lower. Therefore, the cold air outlet 1412 is usually offset close to one side of the fresh air outlet so that the cold air flow and the fresh air flow can mix. However, due to the large temperature difference between the fresh air flow and the cold air flow, when the refrigeration unit and the fresh air unit are both in the on state, the cool air flow in the air will be mixed with the fresh air flow at room temperature, causing the user to feel uncomfortable.

[0076] In order to improve the temperature uniformity of the fresh air flow and the cold air flow, the kitchen air conditioner 10 provided in the embodiment of the present application, please refer to Figures 1 to 6 As shown, by setting a mixed air area 141 on the shell, the mixed air area 141 has a first fresh air outlet 1411 and a cold air outlet 1412 arranged side by side along a first direction, and the cold air outlet 1412 and the first fresh air outlet 1411 are offset near one end of the mixed air area 141, the first fresh air outlet 1411 is connected with the fresh air channel 110, and the cold air outlet 1412 is connected with the refrigeration channel 120. In this way, the fresh air flow blown out through the first fresh air outlet 1411 and the cold air flow blown out through the cold air outlet 1412 are first fully mixed in the mixed air area 141, and then blown into the environment in a concentrated manner, so that the temperature difference between the fresh air flow and the cold air flow can be reduced, thereby improving the temperature uniformity of the fresh air flow and the cold air flow, and then improving the indoor air quality and comfort, and avoiding the problem of user discomfort caused by the large temperature difference between the fresh air flow and the cold air flow.

[0077] For example, Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the air mixing area 141 is in the shape of an elongated strip, and the length direction of the air mixing area 141 is consistent with the width direction of the body 100, and the width direction of the body 100 is as shown in FIG. Figure 1 and Figure 4 The left and right directions of the middle body 100.

[0078] Please continue to refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the first 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 first fresh air outlet 1411, and the air outlet direction of the first 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 first 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, thereby improving the temperature uniformity and enhancing the user's physical comfort.

[0079] In addition, the first air guide plate 400 is movably provided at the mixed air area 141 to open or close the mixed air area 141. When the first air guide plate 400 closes the mixed air area 141, it can prevent water vapor, oil smoke, etc. from entering the fresh air channel 110 and the refrigeration channel 120 to produce odor; when the first air guide plate 400 is in the open state, a guide angle is formed between the first air guide plate 400 and the shell to guide the airflow blown out from the mixed air area 141, thereby improving the directionality of the blown airflow.

[0080] However, when the first fresh air outlet 1411 is set at the end of the mixed air area 141, and the cold air outlet 1412 is offset close to one side of the first fresh air outlet 1411, the cold air outlet 1412 is offset relative to the first air guide plate 400, which may cause the mixed air flow after the fresh air flow and the cold air flow to be unevenly discharged in the length direction of the mixed air outlet. That is, along the length direction of the mixed air area 141, the air flow rate at one end is large and the air flow rate at the other end is small, which may cause the user to feel uncomfortable.

[0081] In order to improve the uniformity of the air outflow in the mixed air area 141, in the embodiment of the present application, Figure 3 and Figure 6 As shown, the first air guide plate 400 is arranged in the air mixing area 141, and an annular air outlet gap 144 is formed between the peripheral wall of the first air guide plate 400 and the outline of the air mixing area 141. In this way, the cold air flow blown out by the cold air outlet 1412 and the fresh air flow blown out by the first fresh air outlet 1411 are fully mixed in the air mixing area 141, and then discharged into the environment along the air outlet gap 144, thereby improving the air outlet uniformity of the air mixing area 141, and then improving the user's physical comfort.

[0082] In some embodiments, the first air guide plate 400 is movably disposed at the air mixing area 141, and the first air guide plate 400 has a first state and a second state relative to the body 100. When the first air guide plate 400 is in the first state, the first air guide plate 400 is buckled on the air mixing area 141, and an annular air outlet gap 144 (such as Figure 3As shown in the figure, the first air guide plate 400 is arranged in a "suspended state" at the air mixing area 141. In this way, the mixed airflow formed by the fresh air flow and the cold air flow mixed in the air mixing area 141 is blown out uniformly along the circumferential direction of the air outlet gap 144, thereby improving the air outlet uniformity of the air mixing area 141 and further improving the user's physical comfort.

[0083] When the first air guide plate 400 moves to the second state, the bottom of the first air guide plate 400 is tilted toward the side away from the body 100, so that a guide angle is formed between the first air guide plate 400 and the surface where the air mixing area 141 is located, that is, there is an inclined angle between the first air guide plate 400 and the surface where the air mixing area 141 is located (such as Figure 6 As shown in ), in this way, the mixed air area 141 can discharge air with high power under the guiding effect of the first air guide plate 400, which can improve the air discharge efficiency, thereby improving the air processing efficiency, for example, improving the cooling efficiency.

[0084] For example, Figure 6 As shown in , when the first air guide plate 400 is in the second state, the inclination angle between the first air guide plate 400 and the surface where the air mixing area 141 is located is 15° to 60°. For example, the inclination angle can be represented by β, and β can be 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., so as to change the diversion direction by adjusting the diversion angle between the first air guide plate 400 and the main body 100, thereby improving the user's physical comfort.

[0085] Among them, such as Figure 3 and Figure 6 As shown, the first air guide plate 400 has a connecting portion 410, which includes but is not limited to a connecting column or a connecting rod. The first air guide plate 400 is rotatably connected to the main body 100 through the connecting portion 410, so that the first air guide plate 400 can rotate relative to the main body 100, thereby allowing the first air guide plate 400 to switch between the first state and the second state.

[0086] In some embodiments, the kitchen air conditioner 10 also includes a wind shield 200, which is movably arranged at the first fresh air outlet 1411. The wind shield 200 is configured to change the air outlet direction of the first fresh air outlet 1411. In this way, the air outlet direction of the first fresh air outlet 1411 is adjusted by the wind shield 200, so that the fresh air flow blown out by the first fresh air outlet 1411 is quickly mixed with the cold air, thereby improving the user's comfort experience.

[0087] For example, Figures 12 to 14As shown, the windshield 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 first 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 first 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 to 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 first fresh air outlet 1411 can be accurately controlled to meet different environments and usage requirements.

[0088] 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.

[0089] 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.

[0090] Please refer to Figure 14 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 first 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.

[0091] In addition, if Figure 4As shown, the outlet area of the cold air outlet 1412 is larger than the outlet area of the first fresh air outlet 1411. In this way, the ambient temperature can be quickly adjusted and the air flow efficiency can be improved.

[0092] Exemplarily, the ratio of the outlet area of the mixed air region 141 to the total outlet area of the first fresh air outlet 1411 and the cold air outlet 1412 is 2:1 to 3:1. In this way, the airflow distribution and air processing efficiency are optimized, thereby improving the user's comfort experience and reducing energy consumption.

[0093] In order to further improve the mixing effect and efficiency of the fresh air flow and the cold air flow in the mixed air area 141, in an embodiment of the present application, 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 the side of the first fresh air outlet 1411. In this way, the outlet of the fresh air 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 the side of the first 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.

[0094] Illustratively, 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.

[0095] In some embodiments, as Figure 7 and Figure 9 As shown, the shell also has a second fresh air outlet 142, which is connected to the fresh air channel 110. In this way, the second fresh air outlet 142 can provide outdoor clean fresh air to the room alone, thereby improving the indoor air quality.

[0096] like Figure 7 As shown, the mixed air area 141, the second fresh air outlet 142 and the oil fume suction port 143 are arranged in sequence from top to bottom on the main body 100. In this way, the functional areas are clearly separated, avoiding interference between airflows, thereby improving air processing efficiency.

[0097] Return to reference Figure 1 and Figure 4As shown, the shell includes a first shell 140a, a second shell 140b and a third shell 140c. Along the front and rear direction of the main body 100, the first shell 140a is connected to the front side of the second shell 140b and extends upward, and the third shell 140c is connected to the rear side of the second shell 140b and extends downward; the mixed air area 141 is arranged on the first shell 140a, the first fresh air outlet 1411 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 1411 are clearly separated to avoid interference between airflows, thereby improving air treatment efficiency.

[0098] 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.

[0099] Please refer to Figure 7 and Figure 8 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.

[0100] 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.

[0101] However, when the second air guide plate 600 and the third shell 140c are assembled, there will be an installation error, which will result in a gap 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 the oil smoke is sucked out, part of the oil smoke airflow will overflow into the environment through the gap (such as Figure 9 ), which results in technical problems with poor air quality in the kitchen.

[0102] Based on the above problems, the kitchen air conditioner 10 provided in the embodiment of the present application is Figures 7 to 10As shown, 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 to say, an 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 second fresh air outlet 142 is set on the second shell 140b. When the oil fume suction port 143 sucks oil fume, the air outlet direction of the second 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 second 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 (as shown in FIG. Figure 10 ), 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.

[0103] Thus, it can be seen that 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 second 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.

[0104] It can be understood that by arranging the second 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 second 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 second fresh air outlet 142 and the installation gap 700 is shortened, thereby ensuring that the fresh air flow blown out by the second 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 separately arranging the second fresh air outlet 142, 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 from the mixed air area 141, thereby improving the indoor air quality and comfort, thereby improving the user experience.

[0105] 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 blown out by the second fresh air outlet is greater than the speed of the rising oil smoke at the installation gap, and the suction force and flow rate of 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.

[0106] Please continue to refer to Figure 10 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 10 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 10 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] It should be noted that the width of the installation gap 700 refers to the width of the installation gap 700. Figure 8 The size of the middle installation gap 700 in the front-to-back direction.

[0111] Please continue to refer to Figures 7 to 10 As shown, the kitchen air conditioner 10 also includes a guide plate 500, which is rotatably arranged at the second fresh air outlet 142. The air outlet direction of the second fresh air outlet 142 is adjusted by rotating the guide plate 500, wherein the guide plate 500 can be switched between a closed state, a forward guiding state, and a backward guiding state.

[0112] When the fume suction port 143 draws in the fume, the guide plate 500 moves to a backward guiding state, and the guide plate 500 guides the air outlet direction of the second fresh air outlet 142 to form an inclined angle with the third shell 140c, so as to guide the fresh air flow at the second fresh air outlet 142 through the guide plate 500, thereby improving the accuracy of the flow direction of the fresh air flow at the second fresh air outlet 142, so that the fresh air flow blown out by the second 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 overflow of fume and improve the adhesion of fume to the surface of the air guide plate, thereby enhancing the user experience.

[0113] Illustratively, the contour shape of the guide plate 500 matches the contour shape of the second fresh air outlet 142. In this way, when the guide plate 500 moves to the closed state, the guide plate 500 closes the second fresh air outlet 142, which 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 second 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.

[0114] When the guide plate 500 is in the open state and when in the non-cooking state, the guide plate 500 moves to the forward guiding state, and the fresh air flow blown out from the second 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.

[0115] In addition, the guide plate 500 can also 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.

[0116] Of course, the guide plate 500 can be connected to the drive motor by means of a rotating shaft, so that the drive motor can drive the guide plate 500 to rotate relative to the main body, thereby switching between the closed state, the forward diversion state, and the backward diversion state, or the guide plate can be driven to swing back and forth by the forward and reverse rotation of the drive motor.

[0117] Please refer to Figure 11 As shown, the kitchen air conditioner also includes a driving mechanism, which is connected to the first air guide plate 400 and the second air guide plate 600 respectively. The driving mechanism is configured to synchronously drive the first air guide plate 400 and the second air guide plate 600 to rotate relative to the main body 100, so that the first air guide plate 400 switches between the first state and the second state while the second air guide plate 600 switches between opening and closing the oil fume suction port. In this way, the first air guide plate 400 and the second air guide plate 600 are driven to move synchronously by the driving mechanism, which simplifies the operating steps, thereby allowing the first air guide plate 400 and the second air guide plate 600 to quickly switch between different states, thereby improving the switching efficiency.

[0118] In summary, in the kitchen air conditioner provided in the embodiment of the present application, a mixed air area and a first air guide plate are arranged on the main body, the mixed air area includes a first fresh air outlet and a cold air outlet arranged side by side along a first direction, and the cold air outlet and the first fresh air outlet are offset near one end of the mixed air area, the first fresh air outlet is connected with the fresh air channel, and the cold air outlet is connected with the refrigeration channel, and the first air guide plate is arranged in the mixed air area, and an annular air outlet gap is formed between the peripheral wall of the first air guide plate and the mouth wall of the mixed air area. In this way, the fresh air airflow blown out through the first fresh air outlet and the cold air airflow blown out through the cold air outlet are first mixed in the mixed air area to form a mixed airflow, and then the mixed airflow formed in the mixed air area is evenly discharged circumferentially through the air outlet gap, thereby improving the uniformity of the cold air blown to the user, thereby improving the user's physical comfort.
