Description

Technical Field

[0001] The present application relates to the technical field of kitchen equipment, and in particular to a kitchen air conditioner. Background Art

[0002] With the continuous improvement of the quality of life, the kitchen, as an indispensable part of family life, is increasingly valued for its environmental comfort. In order to save space and improve integration, kitchen air conditioners not only integrate the function of extracting oil smoke, but also integrate functions such as air conditioning to adjust the kitchen temperature and improve environmental comfort.

[0003] In the related technology, 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. Among them, an air guide plate is provided at the cold air outlet, and the air guide plate is used to guide the cold air flow blown out of the cold air outlet.

[0004] However, in the related art, when the cold air outlet is cooling, the temperature on the side of the air guide plate facing the cold air outlet is lower, causing the water vapor in the air to easily encounter the cold and produce condensation water when it meets the side of the air guide plate facing the cold air outlet. When a certain amount of condensation water accumulates, it will drip along the lower edge of the air guide plate into the inside of the stove or pot, resulting in a poor user experience. Summary of the Invention

[0005] In view of the above problems, an embodiment of the present application provides a kitchen air conditioner, which aims to solve the problem that condensation water is easily formed on the air guide plate and drips into the stove or pot, resulting in a poor user experience.

[0006] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:

[0007] An embodiment of the present application provides a kitchen air conditioner, comprising a main body, wherein a fresh air duct and a refrigeration duct are formed in the main body, and a mixed air outlet is formed on the main body, wherein the mixed air outlet comprises a first fresh air outlet and a cold air outlet, wherein the first fresh air outlet and the cold air outlet are arranged side by side along the length direction of the mixed air outlet, wherein the first fresh air outlet is connected to the fresh air duct, and the cold air outlet is connected to the refrigeration duct;

[0008] a first air guide plate movably disposed at the cold air outlet, the first air guide plate being configured to change an air outlet direction of the cold air outlet;

[0009] A wind shield and a driving mechanism, wherein the wind shield is arranged at the first fresh air outlet, and the driving mechanism is configured to drive the wind shield to move in the front-to-back direction relative to the main body, and the side wall of the wind shield has an air outlet hole connected to the first fresh air outlet; when the driving mechanism drives the wind shield to move in the front-to-back direction, the air outlet direction of the air outlet hole is at least toward the side of the first air guide plate facing the cold air outlet.

[0010] In an embodiment of the present application, a wind shield is provided at the first fresh air outlet, and the wind shield is provided adjacent to the first air guide plate. The first wind shield moves along the front-to-back direction of the first air guide plate under the driving force of the driving mechanism. The first wind shield has an air outlet hole connected to the first fresh air outlet. When the driving mechanism drives the first wind shield to move along the front-to-back direction, the fresh air flow blown out of the first fresh air outlet is blown toward the side of the first air guide plate facing the cold air outlet through the air outlet hole. In this way, the temperature of the side of the first air guide plate facing the cold air outlet can be increased, and the condensation water generated by the water vapor in the air encountering the cold surface of the first air guide plate facing the cold air outlet can be reduced, thereby preventing the condensation water from dripping into the stove or pot, thereby improving the user experience.

[0011] In some embodiments, the wind shield 200 is rotatably disposed at the first fresh air outlet, and the driving mechanism is configured to drive the wind shield 200 to rotate around its own axis to change the position of the air outlet in the front-to-back direction.

[0012] In this way, the wind shield can be moved in the front-rear direction by screwing the wind shield, which has a simple structure, is easy to implement and has low cost.

[0013] In some embodiments, when the air outlet direction of the air outlet is toward the cold air outlet, the fresh air flow blown out of the air outlet and the cold air flow blown out of the cold air outlet are mixed at the mixing outlet and then blown out.

[0014] In this way, the temperature uniformity of the cold air blowing towards the user can be improved, thereby improving the user's physical comfort.

[0015] In some embodiments, the first fresh air outlet is arranged at a position close to the end of one end of the mixed air outlet, and the cold air outlet is arranged on a side close to the first fresh air outlet.

[0016] In this way, the fresh air flow and the cold air are easily mixed at the mixing outlet, thereby improving the user's comfort experience.

[0017] In some embodiments, the outlet area of the cold air outlet is larger than the outlet area of the air outlet hole.

[0018] In this way, the cooling efficiency can be improved and the ambient temperature can be adjusted quickly.

[0019] In some embodiments, the ratio of the air outlet area of the mixed air outlet to the total air outlet area of the air outlet hole and the cold air outlet is 2:1 to 3:1.

[0020] In this way, the fresh air flow and the cold air flow can be fully mixed at the mixing air outlet, thereby improving the uniformity of the cold air temperature blown to the user, thereby improving the user's physical comfort.

[0021] In some embodiments, the first air guide plate has a guide structure on its side surface facing the cold air outlet, and the guide structure extends toward both sides along the length direction of the first air guide plate. The guide structure is configured to guide the condensed water formed by the first air guide plate to both sides of the first air guide plate.

[0022] In this way, the formed condensed water is guided to both sides of the first air guide plate by the guide structure, thereby preventing the condensed water from directly dripping into the stove or pot below.

[0023] In some embodiments, the diversion structure is in at least one of a circular arc shape and an elliptical arc shape.

[0024] In this way, the effect of guiding the condensed water to both sides is improved.

[0025] In some embodiments, the diversion structure is at least one of a diversion protrusion or a diversion groove.

[0026] In this way, the diversion structure is simple, easy to implement and low in cost.

[0027] In some embodiments, a water collection container is provided at each of the two ends of the diversion structure, so that the condensed water diverted to the two ends by the diversion structure is collected in the water collection container.

[0028] In this way, the condensed water directed to both sides is collected in the water storage container, thereby preventing the condensed water from dripping onto the stove from both sides of the first air guide plate, thereby improving the user experience.

[0029] In some embodiments, the water accumulation container is detachably connected to the first air guide plate.

[0030] In this way, it is convenient to disassemble the water accumulation container to clean the condensed water and wash the water accumulation container.

[0031] In some embodiments, the driving mechanism includes a driving motor and a power transmission component, the driving motor is fixed to the main body, and the driving shaft of the driving motor has two opposite rotation directions, the power transmission component is connected to the driving shaft of the driving motor, and the wind shield is connected to the power transmission component; when the driving shaft rotates in different rotation directions, the wind shield is driven by the power transmission component to move forward or backward along the front-to-back direction to change the position of the air outlet in the front-to-back direction.

[0032] In this way, the driving direction of the driving force applied to the power transmission member is changed by the forward and reverse rotation of the driving motor, thereby changing the moving direction of the windshield member.

[0033] In some embodiments, the power transmission member is a worm, and the drive shaft of the drive motor has drive teeth that mesh with the worm.

[0034] In this way, the driving motor drives the worm to rotate, and the worm drives the windshield to rotate. The movement direction of the windshield is controlled by the different rotation directions of the driving motor. The structure is simple, easy to implement and low in cost.

[0035] In some embodiments, the main body further has an oil fume passage, and the main body has an oil fume suction port, which is connected to the oil fume passage and is located below the mixed air outlet.

[0036] In some embodiments, when the wind shield moves forward along the front-to-back direction and extends the first fresh air outlet, the air outlet is opposite to the side edge of the first air guide plate to guide the airflow blown out of the air outlet to the two side surfaces of the first air guide plate.

[0037] In this way, the side edge of the first air guide plate can guide the airflow blown out of the air outlet to the two side surfaces of the air guide plate, so as to increase the contact area between the airflow blown out of the air outlet and the first air guide plate, increase the temperature of the surface of the first air guide plate, and reduce the condensation water generated by the water vapor in the air encountering cooling on the surface of the first air guide plate.

[0038] In some embodiments, the thickness of the side edge of the first air guide plate facing the air outlet increases gradually from the direction of the first air guide plate approaching to the direction away from the air outlet, so as to guide the airflow blown out of the air outlet.

[0039] In this way, the fresh air flow blown out of the air outlet can be guided to the surface of the first air guide plate, thereby improving the efficiency of the fresh air flow blown out of the air outlet to quickly cover the surface of the first air guide plate, so as to quickly increase the temperature of the surface of the first air guide plate and reduce the condensation water generated by the water vapor in the air when it is cooled on the surface of the first air guide plate.

[0040] In addition to the technical problems solved by the embodiments of the present application, the technical features that constitute the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the kitchen air conditioner provided by the embodiments of the present application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific implementation methods.

[0061] 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.

[0062] Please refer to Figure 1 、 Figure 2 、 Figures 7 to 9 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.

[0063] 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 1411. 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 1411, 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 1411 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 1411 to achieve the purpose of indoor heating.

[0064] 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.

[0065] 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 1411 is lower. 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.

[0066] 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 5 As shown, a mixed air outlet 141 is provided on the housing, wherein the mixed air outlet 141 has a first fresh air outlet and a cold air outlet 1411. The mixed air outlet 141 is in a long strip shape, and the first fresh air outlet and the cold air outlet 1411 are arranged side by side along the length direction of the mixed air outlet 141. Figure 1 As shown in FIG, the length direction of the mixing air outlet 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 Left and right direction in .

[0067] Among them, the first fresh air outlet is connected with the fresh air channel 110, and a wind shield 200 is provided at the first fresh air outlet. An air outlet hole 210 connected with the first fresh air outlet is provided on the side wall of the wind shield 200. When fresh air needs to be delivered into the room, the air outlet hole 210 faces the cold air outlet 1411, and the cold air outlet 1411 is connected with the refrigeration channel 120. In this way, the fresh air flow blown out of the first fresh air outlet is blown to one side of the cold air outlet 1411 through the air outlet hole 210, and is mixed with the cold air flow blown out of the cold air outlet 1411 at the mixing air outlet 141, and then is blown into the environment together. In this way, 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, thereby 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.

[0068] Please continue to refer to Figure 1 and Figure 2 As shown, the first fresh air outlet is arranged at a position near the end of one end of the mixing outlet 141, and the cold air outlet 1411 is arranged on a side close to the first fresh air outlet, and the air outlet direction of the first fresh air outlet is toward the cold air outlet 1411, which can increase the mixing area of the fresh air flow blown out by the first fresh air outlet and the cold air flow at the mixing outlet 141, thereby facilitating the full mixing of the fresh air flow and the cold air at the mixing outlet 141, thereby improving the temperature uniformity and enhancing the user's physical comfort.

[0069] In addition, the cold air outlet 1411 can be one or more, so that the flow rate of the cold air flow can be increased, thereby improving the efficiency of cooling or heating, for example, Figure 1 and Figure 2 As shown in the figure, there are two cold air outlets 1411, and the two cold air outlets 1411 are arranged close to the first fresh air outlet at the end, so as to facilitate sufficient mixing of the fresh air flow and the cold air flow, and cool the fresh air flow by the cold air flow to improve the user's physical comfort.

[0070] Please refer to Figures 1 to 5 As shown, the outlet area of the cold air outlet 1411 is larger than the outlet area of the air outlet hole 210, so that the ambient temperature can be adjusted quickly and the cooling efficiency can be improved.

[0071] In addition, the ratio of the outlet area of the mixing outlet 141 to the total outlet area of the first fresh air outlet and the cold air outlet 1411 is 2:1 to 3:1. In this way, the airflow distribution and air treatment efficiency are optimized, and the fresh air flow and the cold air flow can be fully mixed at the mixing outlet 141, thereby improving the uniformity of the cold air temperature blown to the user, thereby improving the user's physical comfort and reducing energy consumption.

[0072] Please refer to Figures 1 to 5 As shown, a first air guide plate 300 is also provided at the mixing air outlet 141, and the first air guide plate 300 is movably provided at the cold air outlet 1411 to open or close the cold air outlet 1411. It should be noted that in the embodiment of the present application, when the first air guide plate 300 closes the cold air outlet 1411, the first air guide plate 300 not only covers the cold air outlet 1411, but also covers at least the rest of the mixing air outlet 141 except the position of the wind shield 200. When the first air guide plate 300 closes the cold air outlet 1411, it can prevent water vapor, oil smoke, etc. from entering the refrigeration channel 120 and generating odor; when the first air guide plate 300 is in the open state, a guide angle is formed between the first air guide plate 300 and the shell to guide the mixed airflow after the cold air flow and the fresh air flow are mixed, thereby improving the directionality of the mixed airflow blown into the environment.

[0073] However, the temperature of the side surface of the first air guide plate 300 facing the cold air outlet 1411 (for example, represented by the inner surface of the first air guide plate 300) is relatively low. Therefore, when water vapor in the environment encounters the inner surface of the first air guide plate 300, it is easily cooled to form condensation water. When a certain amount of condensation water accumulates, it will flow downward along the first air guide plate 300 and directly drip into the stove or pot below the first air guide plate 300, resulting in a poor user experience.

[0074] In order to reduce the formation of condensed water, in the embodiment of this application, please refer to Figures 1 to 5 As shown in, the kitchen air conditioner 10 also includes a driving mechanism, and the wind shield 200 is arranged at the first fresh air outlet and is connected to the driving mechanism. The driving mechanism is used to drive the wind shield 200 to move in the first fresh air outlet along the front-to-back direction of the main body 100, so that the position of the air outlet hole 210 on the wind shield 200 relative to the cold air outlet 1411 in the front-to-back direction can be changed. In this way, when the driving mechanism drives the wind shield 200 to move along the said front-to-back direction, the air outlet direction of the air outlet hole 210 is at least toward the side of the first air guide plate 300 facing the cold air outlet 1411, so that the fresh air flow blown out of the first fresh air outlet is blown toward the side of the first air guide plate 300 facing the cold air outlet 1411 through the air outlet hole 210. In this way, the fresh air flow with higher temperature can increase the temperature of the inner surface of the first air guide plate 300, reduce the condensation water generated by the water vapor in the air encountering the cold on the inner surface of the first air guide plate 300, thereby avoiding the condensation water dripping into the stove or pot, thereby improving the user experience.

[0075] Among them, the wind shield 200 is inserted into the first fresh air outlet and is sealed with the mouth wall of the first fresh air outlet. The wind shield 200 can move in the forward and backward directions only under the driving force of the driving mechanism. In this way, the fresh air flow can be prevented from leaking between the mouth wall of the first fresh air outlet and the outer wall of the wind shield 200.

[0076] In some embodiments, the wind shield 200 is a rotating part, and the driving mechanism can drive the wind shield 200 to rotate around its own axis to change the position of the air outlet 210 in the front-to-back direction. In this way, by screwing the wind shield 200, the wind shield 200 can be moved in the front-to-back direction. The structure is simple, easy to implement, and low in cost.

[0077] For example, Figure 3 As shown in , the wind shield 200 is in the retracted state. At this time, the fresh air flow blown out by the air outlet 210 can blow the rear edge of the inner surface of the first air guide plate 300 (i.e., the side close to the cold air outlet 1411) to avoid the formation of condensation water on the rear edge of the inner surface of the first air guide plate 300; and as shown in Figure 4 and Figure 5 As shown in the figure, the wind shield 200 is in an extended state. At this time, the fresh air flow blown out by the air outlet 210 can blow the front edge of the inner surface of the first air guide plate 300 (that is, the side away from the cold air outlet 1411) to avoid the formation of condensation water on the front edge of the inner surface of the first air guide plate 300; and the driving mechanism can drive the wind shield 200 to reciprocate between the contracted state and the extended state. In this way, the fresh air flow blown out by the air outlet 210 can blow back and forth the front edge and the rear edge of the inner surface of the first air guide plate 300, thereby avoiding the formation of condensation water on the inner surface of the first air guide plate 300.

[0078] In some embodiments, the driving mechanism includes a driving motor and a power transmission component. The driving motor is fixed to the main body, and the driving shaft of the driving motor has two opposite rotation directions. The power transmission component is connected to the driving shaft of the driving motor, and the wind shield 200 is connected to the power transmission component. When the driving shaft rotates in different rotation directions, the wind shield 200 is driven by the power transmission component to move forward or backward in the front-to-back direction to change the position of the air outlet in the front-to-back direction. In this way, the driving direction of the driving force applied to the power transmission component is changed by the forward and reverse rotation of the driving motor, thereby changing the movement direction of the wind shield.

[0079] In some embodiments, the power transmission member is a worm gear, and the windshield member 200 is coaxially connected to the worm gear. The driving shaft of the driving motor has driving teeth, and the driving teeth and the worm gear are engaged. In this way, the driving motor drives the worm gear to rotate, and the worm gear drives the windshield member to rotate. The movement direction of the dry windshield member is determined by the different rotation directions of the driving motor. The structure is simple, easy to implement, and low cost.

[0080] In other embodiments, the driving mechanism includes a driving motor, the driving shaft of the driving motor has two opposite rotation directions, the driving shaft is provided with driving teeth, the wind shield 200 is a cylindrical structure, and the outer peripheral wall of the wind shield has helical teeth matching the driving teeth, and the helical teeth are engaged with the driving teeth. In this way, when the driving shaft rotates forward or reverse, it can drive the wind shield 200 to rotate around its own axis and move in the front-to-back direction to change the position of the air outlet 210 in the front-to-back direction.

[0081] In some embodiments, when the wind shield 200 moves forward in the front-to-back direction and extends the first fresh air outlet, for example, the wind shield 200 can switch between a retracted state and an extended state. When the wind shield 200 is in the extended state, the air outlet 210 is opposite the side edge of the first air guide plate 300 to guide the airflow blown out of the air outlet 210 to the two side surfaces of the first air guide plate 300, that is, the side edge of the first air guide plate 300 diverts the fresh air flow blown out of the air outlet 210 to the two surfaces adjacent to the side edge. In this way, the contact area between the airflow blown out of the air outlet 210 and the first air guide plate 300 can be increased, the surface temperature of the first air guide plate 300 can be increased, and the condensation water generated by the water vapor in the air encountering cooling on the surface of the first air guide plate 300 can be reduced.

[0082] In some embodiments, as the first air guide plate 300 approaches and moves away from the air outlet 210, the thickness of the side edge of the first air guide plate 300 facing the air outlet 210 increases successively to guide the airflow blown out by the air outlet 210. In this way, the fresh air flow blown out by the air outlet 210 can be guided toward the surface of the first air guide plate 300, thereby improving the efficiency of the fresh air flow blown out by the air outlet 210 to quickly cover the surface of the first air guide plate 300, so as to quickly increase the temperature of the surface of the first air guide plate 300 and reduce the condensation water generated when water vapor in the air is cooled on the surface of the first air guide plate 300.

[0083] In addition, please refer to Figure 5 and Figure 6 As shown, the first air guide plate 300 has a guide structure 310 on one side of the surface facing the cold air outlet 1411. The guide structure 310 is arranged along the length direction of the first air guide plate 300 (ie, the width direction of the body 100, as shown in FIG. Figure 5 The guide structure 310 extends toward both sides (left and right directions), and is configured to guide the condensed water formed by the first air guide plate 300 toward both sides of the first air guide plate 300. In this way, the formed condensed water is guided to both sides of the first air guide plate 300 by the guide structure 310, thereby preventing the condensed water from directly dripping into the stove or pot below.

[0084] like Figure 6As shown in the figure, the guide structure 310 is in at least one of a circular arc shape and an elliptical arc shape. For example, along the length direction of the first air guide plate 300, the guide structure 310 bends downward from the middle to both sides to enhance the effect of guiding the condensed water to both sides.

[0085] For example, when there are multiple air guide structures 310, the multiple air guide structures 310 are arranged at intervals along the vertical direction of the first air guide plate 300, wherein the contour shapes of the multiple air guide structures 310 can be at least one of an arc shape and an elliptical shape, that is, the contour shapes of the multiple air guide structures 310 can be the same or different, and the specific adaptive design is based on actual needs, and no specific limitation is made here.

[0086] Please continue to refer to Figure 6 As shown, the guide structure 310 is at least one of a guide protrusion or a guide groove. In this way, the condensed water flows along the extension direction of the guide protrusion, or the condensed water flows along the extension direction of the guide groove. The guide structure 310 is simple, easy to implement, and low in cost.

[0087] In addition, in order to prevent condensed water from dripping onto the stove along the two ends of the guide structure 310, in an embodiment of the present application, there are water accumulation containers at both ends of the guide structure 310, so that the condensed water guided to the two ends by the guide structure 310 is collected in the water accumulation containers. In this way, the condensed water guided to both sides is collected in the water accumulation containers, thereby preventing condensed water from dripping onto the stove from both sides of the first air guide plate 300, thereby improving the user experience.

[0088] Alternatively, when there are multiple guide structures 310, water collection containers can be set at the bottom of both ends of the first air guide plate 300 so that the condensed water dripping along both ends of each guide structure 310 can be collected in the water collection container, thereby improving the user experience.

[0089] In some embodiments, the water accumulation container and the first air guide plate 300 can be integrally formed, which can reduce the installation process and lower the installation cost.

[0090] In other embodiments, the water accumulation container is detachably connected to the first air guide plate 300. For example, the water accumulation container is detachably connected to the first air guide plate 300 by snap connection, screw connection, or magnetic adsorption. This makes it easy to disassemble the water accumulation container to clean the condensed water and wash the water accumulation container.

[0091] In some embodiments, as Figure 2 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.

[0092] like Figure 2 As shown, the mixed air outlet 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.

[0093] In some embodiments,

[0094] Continue to refer to Figure 1 and Figure 2 As shown, the main body 100 has a shell, which 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, that is, the second shell 140b is arranged horizontally, the first shell 140a is located above the second shell 140b and is connected to the front edge of the second shell 140b, and the third shell 140c is located below the second shell 140b and is connected to the rear edge of the second shell 140b; the mixing air outlet 141 is arranged on the first shell 140a, the first fresh air outlet 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 mixing air outlet 141 and the first fresh air outlet are clearly separated, avoiding interference between airflows, thereby improving air treatment efficiency.

[0095] In addition, by arranging the mixing air outlet 141 above the oil fume suction port 143 , the coverage area of the mixing air outlet 141 can be increased, thereby improving the air treatment efficiency.

[0096] 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. Thus, by rotating the second air guide plate 600, the oil fume suction port 143 can be closed or opened. When cooking, the second air guide plate 600 opens the oil fume suction port 143, and a guide angle (such as 0.0015°) is formed between the second air guide plate 600 and the third shell 140c. Figure 2 ), so as to guide the oil smoke to the oil smoke suction port 143 through the second air guide plate 600 to improve the efficiency of sucking oil smoke.

[0097] 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.

[0098] However, there will be installation errors when assembling the second air guide plate 600 and the third shell 140c, which will cause an error gap to be 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 sucking out 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.

[0099] Based on the above problems, the kitchen air conditioner 10 provided in the embodiment of the present application is Figures 7 to 9 As 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 9 ), 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.

[0100] 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.

[0101] It can be understood that by arranging the second fresh air outlet 142 between the mixing outlet 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 of the mixing outlet 141 to the installation gap 700, thereby improving the mixed air flow blown out by the mixing outlet 141, thereby improving the indoor air quality and comfort, thereby improving the user experience.

[0102] 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 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 143 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.

[0103] Please continue to refer to Figure 9 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 9 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 9 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] It should be noted that the width of the installation gap 700 refers to the width of the installation gap 700. Figures 7 to 9 The size of the middle installation gap 700 in the front-to-back direction.

[0108] Please continue to refer to Figures 7 to 9 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] Of course, the guide plate 500 can be connected to the drive motor by means of a rotating shaft, so that the drive motor drives the guide plate 500 to rotate relative to the main body 100, thereby switching between the closed state, the forward diversion state, and the backward diversion state, or the guide plate 500 can be driven to swing back and forth by the forward and reverse rotation of the drive motor.

[0114] In summary, in the embodiment of the present application, a wind shield is provided at the first fresh air outlet, and the wind shield is provided adjacent to the first air guide plate. The first wind shield moves along the front-to-back direction of the first air guide plate under the driving force of the driving mechanism. The first wind shield has an air outlet hole connected to the first fresh air outlet. When the driving mechanism drives the first wind shield to move along the front-to-back direction, the fresh air flow blown out of the first fresh air outlet is blown toward the side of the first air guide plate facing the cold air outlet through the air outlet hole. In this way, the temperature of the side of the first air guide plate facing the cold air outlet can be increased, and the condensation water generated by the water vapor in the air encountering the cold surface on the side of the first air guide plate facing the cold air outlet can be reduced, thereby avoiding the condensation water dripping into the stove or pot, thereby improving the user experience.
