Abstract

This application provides a kitchen air conditioner, relating to the field of kitchen equipment technology, to solve the technical problem of oil fumes and water vapor easily flowing back into the fresh air duct, generating odors. The kitchen air conditioner includes a main body, a guide component, and a drive mechanism. The main body has a first shell and a second shell, with the second shell located above the first shell. The first shell is connected to the rear edge of the second shell and has a gap with the front edge of the second shell, extending towards the front side of the first shell. The main body has a fresh air duct and a smoke collection chamber inside. The first shell has an air intake communicating with the smoke collection chamber, and the second shell has an air outlet communicating with the fresh air duct. The guide component is rotatably disposed at the air outlet and can open and close the air outlet. When the guide component opens the air outlet, the air outlet has a first guide state of forward airflow and a second guide state of backward airflow. Thus, when the air outlet does not blow fresh air outward, the guide component moves to the closed state to prevent oil fumes and water vapor from flowing back into the fresh air duct.

Description

Technical Field

[0001] This application relates to the field of kitchen equipment technology, and more particularly to a kitchen air conditioner. Background Technology

[0002] As living standards continue to improve, the comfort of the kitchen environment, as an indispensable part of family life, is receiving increasing attention. In order to save space and improve integration, kitchen air conditioners not only integrate the function of absorbing oil fumes, but also integrate functions such as air conditioning to regulate the kitchen temperature and improve environmental comfort.

[0003] In related technologies, a kitchen air conditioner includes a casing, an independent fresh air unit and a smoke collection chamber located inside the casing. The smoke collection chamber is connected to a flue, and a fume fan is installed in the flue. The kitchen air conditioner has a fresh air duct connected to the air outlet of the fresh air unit. The casing has a fresh air outlet connected to the fresh air duct and a fume extraction port connected to the smoke collection chamber. When the fume fan is running, the fumes in the kitchen enter the smoke collection chamber through the fume extraction port and are discharged along the flue. Meanwhile, the fresh air flow generated by the fresh air unit is discharged from the fresh air outlet through the fresh air duct to purify the air in the kitchen.

[0004] However, fumes and moisture can easily flow back into the fresh air duct through the fresh air outlet and adhere to the walls of the fresh air duct. Over time, this can easily breed odors and pollute the fresh air flow blown out from the subsequent fresh air outlet. Utility Model Content

[0005] In view of the above problems, this application provides a kitchen air conditioner, which aims to solve the problem that oil fumes and water vapor backflow and adhere to the wall of the fresh air duct, which easily breeds odors and pollutes the fresh air flow blown out from the subsequent fresh air outlet.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] This application provides a kitchen air conditioner, including:

[0008] The body has a first shell and a second shell, the second shell is located above the first shell, and the first shell is connected to the rear edge of the second shell and has a gap with the front edge of the second shell. The body has a fresh air channel and a smoke collection chamber inside, the first shell has an air intake that communicates with the smoke collection chamber, and the second shell has an air outlet that communicates with the fresh air channel.

[0009] The air guide is rotatably disposed at the air outlet and can open and close the air outlet under the drive of the first drive mechanism. When the air guide opens the air outlet, the first drive mechanism drives the air guide to rotate so that the air outlet has a first air guide state of forward airflow and a second air guide state of backward airflow.

[0010] In this embodiment, a guide element and a first driving mechanism are provided at the air outlet. The guide element opens and closes the air outlet under the drive of the first driving mechanism. On the one hand, when the guide element closes the air outlet, it blocks the air outlet to prevent oil fumes, water vapor, etc. from flowing back into the fresh air channel and adhering to the wall of the fresh air channel to produce odors, thereby improving the cleanliness of the fresh air flow when the air outlet is open. On the other hand, when cooking, the guide element rotates to open the air outlet, and the first driving mechanism can drive the guide element to rotate so that the air outlet has a first guiding state of forward airflow and a second guiding state of backward airflow, thereby accelerating the replacement of indoor air with clean outdoor air and improving indoor air quality.

[0011] In some embodiments, when the first driving mechanism drives the guide to rotate to close the air outlet, the guide completely blocks the air outlet.

[0012] This design, when the air outlet is closed, further prevents oil fumes and moisture from flowing back into the fresh air duct and adhering to the duct wall to produce odors, thereby improving the cleanliness of the fresh air flow when the air outlet is open.

[0013] In some embodiments, when the air outlet is in the second flow-guiding state of rearward flow, the angle of inclination between the flow guide and the first housing is 15° to 60°.

[0014] This setting improves the accuracy of guiding the fresh air flow backward.

[0015] In some embodiments, when the air outlet is in a first airflow guiding state with the air outlet facing forward, the angle between the airflow guide and the lower surface of the second housing is 15° to 60°.

[0016] This setting improves the accuracy of guiding the fresh airflow forward.

[0017] In some embodiments, when the room is not in a cooking state and the indoor air quality is poor, the first drive mechanism drives the air guide to open the air outlet and swing back and forth in the front-back direction, so that the air outlet switches between the first air guide state of forward airflow and the second air guide state of backward airflow.

[0018] This setup increases the area covered by the fresh airflow, thereby accelerating the exchange of indoor air for clean outdoor air.

[0019] In some embodiments, the kitchen air conditioner further includes an air quality detector and a controller. The controller is signal-connected to the air quality detector and the first drive mechanism, respectively. The air quality detector is configured to detect indoor air quality so that the controller controls the first drive mechanism to change the motion state of the air guide based on the detection result of the air quality detector.

[0020] With this setup, indoor air quality can be detected by an air quality sensor, and based on the detection results, the controller can automatically control the first drive mechanism to change the movement state of the air guide, thereby enhancing the intelligence of the kitchen air conditioner.

[0021] In some embodiments, the second housing has a first limiting structure and a second limiting structure. When the air outlet is in a second flow guiding state of rearward airflow, the flow guiding member abuts against the first limiting structure. When the air outlet is in the first flow guiding state of forward airflow, the flow guiding member abuts against the second limiting structure.

[0022] This configuration, through the first and second limiting structures, limits the movement of the guide component, thereby improving the accuracy of the guide component's movement position.

[0023] In some embodiments, both the first limiting structure and the second limiting structure are limiting protrusions.

[0024] This design results in a simple, easy-to-implement, and low-cost limit structure.

[0025] In some embodiments, the air quality detection device includes at least one of a particulate matter detector and a gas detector.

[0026] This setup can improve the accuracy and reliability of the air quality detection structure.

[0027] In some embodiments, the first driving mechanism includes a drive motor, the drive shaft of which is connected to the air guide, and the drive shaft has two opposite rotation directions to drive the air guide to open and close the air outlet.

[0028] With this configuration, the first drive mechanism has a simple structure, is easy to implement, and has low cost.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0046] Please refer to Figure 1 As shown in the figure, this application embodiment provides a kitchen air conditioner 10, which includes a main body 100 and a fume fan. The main body 100 has a housing, and the main body 100 has a smoke collection chamber 150 and a flue connecting the smoke collection chamber 150 and the outside. The fume fan is disposed in the smoke collection chamber 150, the flue, or other locations. The housing is provided with an air intake 111 that communicates with the smoke collection chamber 150. The air intake 111 is connected to the smoke collection chamber 150. The fume fan is used to generate negative pressure to draw in oil fumes, so that the oil fume airflow enters the smoke collection chamber 150 through the air intake 111 and is discharged into the room through the flue.

[0047] In addition, in some embodiments, the kitchen air conditioner 10 also includes a fresh air unit, and the body 100 has a fresh air channel 160 connected to the air outlet of the fresh air unit. The fresh air unit is used to generate fresh air flow, and the housing has an air outlet 121 connected to the fresh air channel 160. In this way, the fresh air flow generated by the fresh air unit can be discharged into the environment through the fresh air channel 160 and the air outlet 121 to improve the air quality of the environment.

[0048] Please refer to Figure 1 As shown, the housing has a first housing 110 and a second housing 120. The first housing 110 is, for example, the housing facing the user when cooking food, that is, the front side of the main body 100 faces the user. The second housing 120 is located above the first housing 110, and the rear edges of the first housing 110 and the second housing 120 are connected. There is a gap between the front edges of the first housing 110 and the second housing 120. The first housing 110 has an air intake 111 for absorbing oil fumes, and the second housing 120 has an air outlet 121 for blowing out fresh air. In this way, when cooking, the fume fan is started, and the cooking fumes can be drawn into the smoke collection chamber 150 through the air intake 111 and discharged through the flue. The air outlet 121 is usually oriented away from the first housing 110 to output fresh air into the room, thereby purifying the air in the environment.

[0049] In addition, to improve the efficiency of fume extraction, in some embodiments, please continue to refer to... Figure 1As shown, a guide plate 130 is movably disposed at the air intake 111. For example, the top of the guide plate 130 is rotatably connected to the first housing 110. Thus, by rotating the guide plate 130, the air intake 111 can be closed or opened. When cooking, the guide plate 130 opens the air intake 111, and a guiding angle is formed between the guide plate 130 and the first housing 110 to guide the oil fumes to the air intake 111, thereby improving the efficiency of oil fume extraction.

[0050] Ideally, when the air guide plate 130 and the first housing 110 form a guiding angle, there is no gap between the upper end face of the air guide plate and the first housing 110, which can prevent some of the oil fume from overflowing outward between the top end face of the air guide plate 130 and the first housing 110 when the oil fume is sucked up.

[0051] However, during assembly, there may be installation errors between the air guide plate 130 and the first housing 110. This can result in a gap between the upper surface of the air guide plate 130 and the surface of the first housing 110 when a guide angle is formed between them. Consequently, during the extraction of fumes, some of the fumes will overflow into the environment through this gap (e.g., when the fumes are extracted). Figure 3 (as shown in the image), which leads to technical problems such as poor air quality in the kitchen.

[0052] Based on the above problems, this application provides a kitchen air conditioner 10, which aims to solve the technical problem of oil fumes overflowing outward due to error gap between the air guide plate 130 and the first housing 110.

[0053] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0054] Please refer to Figure 1 , Figure 3 and Figure 4 As shown, in the kitchen air conditioner 10 provided in this embodiment, when the air guide plate 130 and the first housing 110 form a guiding angle, an installation gap 140 is provided between the top end face of the air guide plate 130 and the surface of the first housing 110. That is, an installation gap 140 with a certain width is intentionally provided between the top end face of the air guide plate 130 and the surface of the first housing 110. In addition, when the air intake 111 draws in oil fumes, the air outlet 121 is directed at least towards the first housing 110, and the fresh air flow blowing towards the first housing 110 flows from top to bottom along the plate surface of the first housing 110. In this way, when the fresh air flow passes through the installation gap 140, the fresh air flow and the oil fume flow form an opposing force at the installation gap 140 (e.g., Figure 3As shown in the figure, this can suppress the overflow of oil fumes into the environment, thereby improving air quality and enhancing the user experience; and the installation gap 140 formed between the air guide plate 130 and the first housing 110 reduces the installation difficulty and cost compared to the ideal state of having no installation gap 140.

[0055] Therefore, in this embodiment, firstly, when a guiding angle is formed between the air guide plate 130 and the first housing 110 on the main body 100, an installation gap 140 is provided between the top end face of the air guide plate 130 and the surface of the first housing 110. Secondly, the fresh airflow from the air outlet 121 is at least partially guided to the first housing 110, so that the fresh airflow blowing towards the first housing 110 flows from top to bottom along the surface of the first housing 110 and the air guide plate 130. The flow direction of the fresh airflow through the installation gap 140 is opposite to the overflow direction of the oil fume airflow at the installation gap 140. In this way, the oil fume airflow can be suppressed from overflowing outward from the installation gap 140 by the principle of mutual opposition between the fresh airflow and the oil fume airflow. That is, the fresh airflow is equivalent to forming an air curtain protective layer at the installation gap 140 to block the oil fume airflow, thereby improving the effect of suppressing the diffusion of oil fumes. In addition, the installation difficulty between the air guide plate 130 and the first housing 110 can be reduced, thereby reducing the installation cost.

[0056] To ensure that the fresh airflow suppresses the overflow of oil fume at the installation gap 140, the velocity of the fresh airflow blown out of the air outlet 121 is greater than the velocity of the rising oil fume at the installation gap. The suction force and velocity of the air intake 111 are not equal to the suction force and velocity at the installation gap 140, so as to further improve the reliability and stability of the air curtain protective layer formed at the installation gap 140, thereby further improving the effect of suppressing the diffusion of oil fume.

[0057] Please continue to refer to Figure 3 As shown, the fresh airflow from the surface of the first housing 110 to the guide plate 130, under the suction force of the oil fume extraction, will flow along the outer surface of the guide plate 130 (e.g., Figure 3 The upper surface of the air guide plate 130) guides the inner surface of the air guide plate 130 (such as... Figure 3 The airflow flows along the lower surface of the guide plate 130 and is drawn into the smoke collection chamber 150 through the air intake 111 along with the oil fume airflow. In this way, the fresh airflow flowing along the surface of the guide plate 130 can form an airflow protective layer on the surface of the guide plate 130 to prevent oil fumes from adhering to the surface of the guide plate 130, thereby improving the cleanliness of the guide plate 130.

[0058] Therefore, the kitchen air conditioner 10 provided in this application embodiment can not only suppress the oil fumes from overflowing outward from the installation gap 140 between the air guide plate 130 and the first housing 110, but also form an airflow protection layer to improve the situation of oil fumes adhering to the surface of the air guide plate 130 and enhance the user's experience.

[0059] For example, the width of the installation gap 140 is 1mm to 10mm. For instance, when the air guide plate 130 and the first housing 110 form a flow guiding angle, the installation gap 140 between the top end face of the air guide plate 130 and the surface of the first housing 110 is 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc., to ensure that the intensity of the fresh airflow at the installation gap 140 is greater than the intensity of the oil fume airflow at the installation gap 140, so that they can counteract each other at the installation gap 140, thereby suppressing the diffusion of oil fumes and improving the effect of suppressing the diffusion of oil fumes.

[0060] Therefore, in this embodiment, the width of the installation gap 140 includes, but is not limited to, 1mm to 5mm. As long as the fresh airflow and the oil fume airflow are opposed at the installation gap 140 and the oil fume can be suppressed from overflowing outward from the installation gap 140, no specific limitation is made here.

[0061] It should be noted that the 140mm installation gap refers to a width within, for example... Figures 2 to 4 The installation clearance of 140 is the dimension in the front-to-back direction.

[0062] Because the air outlet is located above the air inlet, residual oil fumes and moisture in the environment can easily flow back into the fresh air duct 160 from the air outlet and adhere to the wall surface of the fresh air duct 160. Over time, this can easily breed odors. The fresh air flow that is subsequently blown out of the fresh air duct 160 will be contaminated by the oil fumes and other contaminants adhering to the wall surface of the fresh air duct 160, resulting in the fresh air flow also containing odors and oil stains, reducing the cleanliness of the fresh air flow. In addition, the fresh air flow along the surface of the first housing and the surface of the air guide plate is not easy to form a clean air flow protective layer. Oil stains and other contaminants carried in the fresh air flow are easy to adhere to the surface of the air guide plate and the surface of the first housing, thus affecting the user experience.

[0063] Please refer to Figures 1 to 5As shown, the kitchen air conditioner 10 also includes a first driving mechanism and a guide member 200. The guide member 200 is movably disposed at the air outlet 121, and the first driving mechanism drives the guide member 200 to move, so that the guide member 200 closes or opens the air outlet 121. When the guide member 200 is in the open state, the guide member 200 is used to adjust the air outlet direction of the air outlet 121. For example, the guide member 200 is used to guide the air outlet direction of the air outlet 121 toward the surface of the first housing 110, so that the air outlet 121 is in a second guiding state of rearward air outlet; the guide member 200 can also guide the air outlet direction of the air outlet 121 toward the front side of the first housing 110, so that the air outlet 121 is in a first guiding state of forward air outlet; or, the guide member 200 can close the air outlet 121, so that the guide member 200 is in the closed state.

[0064] Specifically, such as Figure 2 As shown, when not cooking and the indoor air cleanliness is good (i.e., the fresh air unit does not need to be activated to purify the air), the first drive mechanism drives the guide 200 to close the air outlet 121, that is, the guide 200 moves to the closed state. This prevents residual oil fumes, water vapor, etc. in the environment from flowing back onto the wall of the fresh air duct 160 and producing odors. This also prevents odors generated in the fresh air duct 160 from being blown out with the subsequent fresh air flow, thus affecting the cleanliness of the fresh air flow. It also improves the cleanliness of the clean airflow protective layer formed when the subsequent fresh air flow is guided backward, protecting the surface of the guide plate and the first housing, preventing oil fumes from adhering to the surface of the guide plate and the first housing. Figure 3 As shown, when cooking, the air guide plate 130 opens the air intake, the air guide 200 opens the air outlet 121, and the air outlet 121 is in the second airflow guiding state of rearward airflow. That is to say, the air guide 200 can guide the airflow direction of the air outlet 121 to form an inclined angle with the first housing 110, so as to guide the fresh airflow at the air outlet 121 through the air guide 200, improve the accuracy of the flow direction of the fresh airflow at the air outlet 121, so that the fresh airflow blown out of the air outlet 121 flows from top to bottom along the surface of the first housing 110 to the air guide plate 130, and flows along the plate surface of the air guide plate 130, and forms a countercurrent with the oil fume airflow at the installation gap 140, so as to suppress the oil fume from overflowing outward and improve the adhesion of oil fume to the surface of the air guide plate 130, thereby improving the user experience; Figure 4 As shown, after cooking is finished, the range hood can be set to a low setting to absorb the small amount of residual oil fumes floating in the room. At this time, no more oil fumes are generated in the stove area. At this time, the guide can rotate forward so that the air outlet 121 is in the first guide state of forward airflow. In this way, the generated fresh air flow can replace the indoor air with clean outdoor air, improve the indoor air quality, and enhance the user experience.

[0065] For example, the air guide 200 includes, but is not limited to, a deflector plate whose profile shape matches the profile shape of the air outlet 121.

[0066] In some embodiments, when the first driving mechanism drives the guide to rotate to close the air outlet, the guide 200 completely blocks the air outlet 121. This further prevents oil fumes, water vapor, etc. from entering the fresh air duct 160 and adhering to the wall of the fresh air duct 160 to produce odors, thereby improving the user experience.

[0067] In some embodiments, the guide member 200 is disposed at the air outlet 121 and rotatably connected to the second housing 120. Thus, by rotating the guide member 200 relative to the second housing 120, the guide member 200 can open or close the air outlet 121. When the air outlet 121 is open, the guide member 200 can guide the fresh air flow to the rear or front side, so that the air outlet 121 has a first guiding state of forward airflow and a second guiding state of rear airflow. The switching method and structure are simple, easy to implement, and low in cost.

[0068] For example, the air guide 200 can be rotatably connected to the second housing 120 via a rotating shaft, so that the air guide 200 can rotate relative to the second housing 120, thereby allowing the air guide 200 to open or close the air outlet 121 by rotating, thus meeting different needs.

[0069] In some embodiments, such as Figure 3 As shown, when the air outlet 121 is in the second guiding state, the angle of inclination between the guide member 200 and the first housing 110 is 15° to 60°, and the angle of inclination is represented by β, for example, so that the fresh airflow blowing from the air outlet to the first housing 110 is above the air intake 111, and then flows from top to bottom along the surface of the first housing, so that the fresh airflow can counteract the oil fumes at the installation gap 140 to suppress the oil fume overflow; wherein, the angle of inclination β between the guide member 200 and the first housing 110 is 15°, 20°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., as long as the contact point between the fresh airflow blowing to the first housing 110 and the first housing 110 is above the air intake 111, so that the fresh airflow can counteract the oil fume airflow at the installation gap 140 by flowing from top to bottom along the surface of the first housing 110.

[0070] Additionally, please refer to Figure 4As shown, when the air outlet 121 is in the first guiding state, the angle between the guide member 200 and the lower surface of the second housing 120 is 15° to 60°, for example, represented by α, so that the guide member 200 guides the fresh air flow to the front side of the first housing 110. The angle α between the guide member 200 and the lower surface of the second housing 120 is 15°, 20°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc., as long as it can guide the fresh air flow to the front side.

[0071] The air guide 200 can rotate relative to the second housing 120, either manually, mechanically, or electrically. As long as the air guide 200 can rotate relative to the second housing 120 to change the direction of the fresh air flow, no specific restrictions are imposed here.

[0072] In some embodiments, the first driving mechanism is connected to the air guide 200. The first driving mechanism is used to drive the air guide 200 to move relative to the second housing 120 to open or close the air outlet 121 or adjust the air outlet direction of the air outlet 121. In this way, by driving the air guide 200 to rotate relative to the second housing 120 through the first driving mechanism, when the air outlet 121 is in the open state, the rotation of the air guide 200 can switch the air outlet direction of the air outlet 121 between the first air guide state and the second air guide state, thereby improving the accuracy of the air outlet direction and the intelligence of the kitchen air conditioner 10.

[0073] For example, the first drive mechanism includes a first drive motor, the drive shaft of the first drive motor having two opposite rotation directions, the drive shaft of the first drive motor can be directly connected to the guide member 200, so that the guide member 200 can be driven to move in the front-back direction by the forward and reverse rotation of the first drive motor, thereby opening and closing the air outlet 121 or adjusting the air outlet direction of the air outlet 121; another example, the first drive mechanism may also include a transmission gear set, the transmission gear set being connected between the drive shaft of the first drive motor and the guide member 200, so that the speed and direction of the drive shaft of the first drive motor can be changed by the transmission gear set, so that the guide member 200 rotates according to a preset speed and rotation direction, thereby improving the guiding accuracy of the fresh air flow.

[0074] Please refer to Figure 5As shown, by setting the first driving mechanism, the air guide 200 can also be driven to swing back and forth in the front and back direction. In this way, when the indoor air quality is poor in the non-cooking state, the first driving mechanism drives the air guide 200 to swing back and forth in the front and back direction. For example, the first driving mechanism drives the air guide 200 to swing back and forth between the position corresponding to the first air guide state and the position corresponding to the second air guide state. That is, the air outlet 121 switches between the first air guide state and the second air guide state. In this way, the coverage of the fresh air flow can be increased, thereby quickly replacing the indoor air with clean outdoor air and improving the air purification efficiency.

[0075] In some embodiments, the kitchen air conditioner 10 further includes an air quality detector and a controller (not shown in the figure). The controller is signal-connected to the air quality detector and the first drive mechanism, respectively. The air quality detector is configured to detect indoor air quality. When the indoor air quality is poor and the kitchen is not in a cooking state, the controller controls the first drive mechanism to drive the air guide to swing back and forth between the position corresponding to the first air guide state and the position corresponding to the second air guide state, so as to increase the coverage of the fresh air flow, thereby quickly replacing the indoor air with clean outdoor air and improving the air purification efficiency.

[0076] The air quality detection device includes, but is not limited to, at least one of a particulate matter detector and a gas detector, for detecting PM2.5, PM10, particulate matter composition of cooking fumes, and harmful gases in cooking fumes.

[0077] In addition, the second housing 120 has a first limiting structure and a second limiting structure (not shown in the figure). When the air outlet 121 is in the second flow guiding state, the flow guiding member 200 abuts against the first limiting structure; when the air outlet 121 is in the first flow guiding state, the flow guiding member 200 abuts against the second limiting structure. In this way, the accuracy and reliability of the flow guiding member 200 switching between the first flow guiding state and the second flow guiding state can be improved, thereby improving the reliability of the air outlet direction.

[0078] For example, both the first limiting structure and the second limiting structure include, but are not limited to, limiting protrusions, as long as they can limit the flow guide 200 at the positions corresponding to the first flow guide state and the second flow guide state, respectively, without specific limitations.

[0079] In some embodiments, the kitchen air conditioner 10 further includes a second drive mechanism connected to the air guide plate 130. The second drive mechanism is configured to drive the air guide plate 130 to rotate relative to the first housing 110, so that the air guide plate 130 closes or opens the air intake 111. By driving the air guide plate 130 to rotate relative to the first housing 110 through the second drive mechanism, the intelligence of the kitchen air conditioner 10 is further improved.

[0080] For example, the second drive mechanism includes a second drive motor, the drive shaft of which can be directly connected to the air guide plate 130 to drive the air guide plate 130 to rotate relative to the second housing 120; in addition, the second drive mechanism may also include a transmission gear set, which is connected between the drive shaft of the second drive motor and the air guide plate 130 to change the speed and direction of the drive shaft of the second drive motor, so that the air guide plate 130 rotates according to a preset speed and rotation direction, thereby improving the guiding accuracy of the oil fume airflow.

[0081] Of course, the air guide plate 130 can also be rotated manually or mechanically to open or close the air intake 111.

[0082] In summary, the kitchen air conditioner provided in this application embodiment has a guide member and a first driving mechanism at the air outlet. The guide member opens and closes the air outlet under the drive of the first driving mechanism. On the one hand, when the guide member closes the air outlet, it blocks the air outlet to prevent oil fumes, water vapor, etc. from flowing back into the fresh air duct and adhering to the wall of the fresh air duct to produce odors, thereby improving the cleanliness of the fresh air flow when the air outlet is open. On the other hand, during cooking, the guide member rotates to open the air outlet, and the first driving mechanism can drive the guide member to rotate so that the air outlet has a first guiding state of forward airflow and a second guiding state of backward airflow, thereby accelerating the replacement of indoor air with clean outdoor air and improving indoor air quality.

[0083] Furthermore, when the air guide plate forms a guiding angle with the first housing on the main body, an installation gap is set between the top end face of the air guide plate and the surface of the first housing. On the other hand, when extracting fumes, the air outlet is directed at least towards the first housing. In this way, the fresh airflow blowing towards the first housing flows from top to bottom along the plate surface of the first housing, so that the fresh airflow and the fumes flow at the installation gap form a countercurrent, thereby suppressing the fumes from overflowing into the environment, thereby improving air quality and enhancing the user experience.

[0084] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0085] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0086] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0087] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
