Description

Technical Field

[0002] The kitchen environment is usually bad when cooking. In summer, the hot weather and the heat from the stove make the kitchen very hot and humid, and in winter, the cold weather makes users not want to cook. In order to solve the problem of hot and cold in the kitchen, some users choose to install air conditioning equipment in the kitchen. Installing air conditioners separately has problems such as installing external units, damaging the exterior walls, increasing costs, and the internal unit of the air conditioner being corroded by kitchen fumes. Some kitchen air conditioners use relatively good filter components to filter the air inlet of the air conditioner, which not only increases wind resistance and cost, but also cannot filter cleanly, making subsequent cleaning troublesome. In addition, installing an air conditioner means closing doors and windows to improve the cooling effect, which will lead to the accumulation of pollutants in the kitchen and make the kitchen environment worse.

[0032] The following embodiments illustrate the present invention, but the present invention is not limited by these embodiments. Modifying the specific embodiments of the present invention or making equivalent replacements for some technical features without departing from the spirit of the present invention scheme shall all be covered within the scope of the technical solution claimed by the present invention.

[0033] Embodiment 1

[0034] As Figure 1-2As shown in the figure, a range hood air conditioner according to this embodiment includes a range hood main body 1, a range hood fan assembly (not shown in the figure), a control assembly (not shown in the figure), and a refrigeration and heating device 2 electrically connected to the control assembly. The range hood main body 1 is provided with a flue 101. The range hood fan assembly is disposed in the flue 101 and electrically connected to the control assembly for sucking the cooking fumes generated during the cooking process. In addition, an air inlet 102, an air outlet 103, and an air duct 104 are provided on the range hood main body 1. The two ends of the air duct 104 are respectively communicated with the air inlet 102 and the air outlet 103, and the air duct 104 is communicated with the flue 101. The refrigeration and heating device 2 is disposed in the air duct 104 and can be switched between a refrigeration and heat dissipation mode and a heating and heat dissipation mode, so that the refrigeration and heating device 2 can provide cold air or hot air for the user through the air outlet 103. In this embodiment, the refrigeration and heat dissipation mode specifically means that the refrigeration and heating device 2 can provide cold air for the air outlet 103 and can dissipate heat through the flue 101 at the same time. The heating and heat dissipation mode specifically means that the refrigeration and heating device 2 can provide hot air for the air outlet 103 and can dissipate heat through the flue 101 at the same time.

[0035] It can be seen that for a range hood air conditioner according to this embodiment, by providing an air inlet 102, an air outlet 103, and an air duct 104 that are interconnected on the range hood main body 1, and a refrigeration and heating device 2 that can be switched between a refrigeration and heat dissipation mode and a heating and heat dissipation mode is disposed in the air duct 104. Compared with the solution of installing an air conditioner in the kitchen, the structure of the present invention is more compact. It can not only refrigerate in summer and heat in winter, but also prevent the refrigeration and heating device 2 from being corroded by kitchen fumes, improve the kitchen environment, and enhance the user experience. In addition, by connecting the air duct 103 with the flue 101, it realizes the full utilization of the range hood fan assembly to dissipate heat or cold for the refrigeration and heating device 2, improves the utilization rate of the range hood fan assembly, and reduces the manufacturing cost.

[0036] Specifically, the range hood main body 1 includes a box body 11 and a smoke collecting hood 12. The smoke collecting hood 12 is disposed at the bottom of the box body 11 and communicated with the box body 11. Part of the flue 101 is disposed in the smoke collecting hood 12, and a flue 101 inlet is provided at the bottom of the smoke collecting hood 12. Another part of the flue 101 is disposed in the box body 11, and a flue 101 outlet is provided at the top of the box body 11. The air inlet 102 is provided at the top of the box body 11, and the air outlet 103 is provided on the front of the smoke collecting hood 12 for blowing cold air or hot air towards the user. Part of the air duct 104 is disposed in the smoke collecting hood 12, and another part of the air duct 104 is disposed in the box body 11.

[0037] As Figure 2-5As shown in the figure, specifically, the refrigeration and heating device 2 includes a refrigeration and heating component 21, a wind guiding mechanism 22, a driving mechanism, and a air supply component 23. Among them, the refrigeration and heating component 21 is arranged in the air duct 104 and is electrically connected to the control component. And the refrigeration and heating component 21 has a hot air duct 1041 and a cold air duct 1042, or the refrigeration and heating component 21 divides part of the air duct 104 into a hot air duct 1041 and a cold air duct 1042. The hot air duct 1041 is respectively communicated with the air inlet 102, the air outlet 103, and the flue 101. The cold air duct 1042 is respectively communicated with the air inlet 102, the air outlet 103, and the flue 101. The wind guiding mechanism 22 is rotatably arranged in the range hood main body 1 and can move between a refrigeration position and a heating position, and is used to control the on-off of the hot air duct 1041 with the air outlet 103 and the flue 101, and to control the on-off of the cold air duct 1042 with the air outlet 103 and the flue 101. The driving mechanism is arranged on the range hood main body 1 and is electrically connected to the control component, and the driving mechanism is connected to the wind guiding mechanism 22 to control the rotation of the wind guiding mechanism 22 between the refrigeration position and the heating position. The air supply component 23 is arranged in the air duct 104 and is electrically connected to the control component, and is used to blow cold air or hot air to the air outlet 103. Thus, the driving mechanism can be used to control the rotation of the wind guiding mechanism 22 between the refrigeration position and the heating position, so as to realize the switching between the refrigeration and heat dissipation mode and the heating and cold dissipation mode of the refrigeration and heating device 2.

[0038] In this embodiment, when the wind guiding mechanism 22 is controlled by the driving mechanism to be in the refrigeration position, the wind guiding mechanism 22 can conduct the cold air duct 1042 with the air outlet 103 and disconnect the cold air duct 1042 from the flue 101. At the same time, it can control the hot air duct 1041 to be conducted with the flue 101 and disconnect the hot air duct 1041 from the air outlet 103. At this time, the refrigeration and heating component 21 works to generate cold air and hot air. The cold air is blown by the air supply component 23 through the air outlet 103 to the user, realizing providing cold air for the user, while the hot air is inhaled into the flue 101 by the range hood fan component, realizing dissipating heat for the refrigeration and heating component 21 through the range hood fan component.

[0039] When the wind guiding mechanism 22 is controlled by the driving mechanism to be in the heating position, the wind guiding mechanism 22 can conduct the hot air duct 1041 with the air outlet 103 and disconnect the hot air duct 1041 from the flue 101. At the same time, it can control the cold air duct 1042 to be disconnected from the air outlet 103 and conduct the cold air duct 1042 with the flue 101. At this time, the refrigeration and heating component 21 works to generate cold air and hot air. The hot air is blown by the air supply component 23 through the air outlet 103 to the user, realizing providing hot air for the user, while the cold air is inhaled into the flue 101 by the range hood fan component, realizing dissipating cold for the refrigeration and heating component 21 through the range hood fan component.

[0040] Such as Figure 4 and Figure 6As shown, specifically, the refrigeration and heating component 21 includes a refrigeration and heating element 211 and a radiator 212. In the middle section of the air duct 104 (i.e., the lower end of the air duct 104 inside the box body 11), there is a vertically arranged fixing seat 107, and the fixing seat 107 is annular. The refrigeration and heating element 211 is installed on the fixing seat 107 and divides the middle section of the air duct 104 into a hot air duct 1041 and a cold air duct 1042. The refrigeration and heating element 211 has a cold end located in the cold air duct 1042 and a hot end located in the hot air duct 1041, and radiators 212 are respectively connected to the cold end and the hot end. Preferably, the refrigeration and heating element 211 is a semiconductor, and the radiator 212 is composed of several heat dissipation fins. Thus, it can be realized to refrigerate in summer through the cold end or heat in winter through the hot end, and the radiator 212 is used to dissipate cold for the cold end and dissipate heat for the hot end.

[0041] As Figure 2-5 shown, specifically, the hot air duct 1041 is connected to the flue 101 through a heat dissipation channel 105. The air guiding mechanism 22 includes two pull rods 221, a partitioning part 222 and an air guiding part 223. The two pull rods 221 are arranged side by side at intervals, and both ends of each pull rod 221 are respectively connected to the partitioning part 222 and the air guiding part 223. The partitioning part 222 is used to control the on-off of the air outlet 103 and the cold air duct 1042 and the on-off of the air outlet 103 and the hot air duct 1041. The air guiding part 223 is arranged at an interval with the partitioning part 222 and is used to control the on-off of the hot air duct 1041 and the heat dissipation channel 105. Thus, when the air guiding mechanism 22 is driven by a driving mechanism to rotate between the refrigeration position and the heating position, it is effectively ensured that the partitioning part 222 can control the on-off of the air outlet 103 and the cold air duct 1042 and the hot air duct 1041, and the air guiding part 223 controls the on-off of the hot air duct 1041 and the heat dissipation channel 105.

[0042] Preferably, the partitioning part 222 is a partition board, and the included angle between the partitioning part 222 and the pull rod 221 is a right angle. The air guiding part 223 is a telescopic air guiding board, and the end of the air guiding part 223 far from the pull rod 221 is fixedly connected to the inner side wall of the hot air duct 1041 near the entrance of the heat dissipation channel 105 or the inner side wall of the upper side wall of the heat dissipation channel 105. More preferably, the end of the air guiding part 223 far from the pull rod 221 is fixedly connected to the inner side wall of the upper side wall of the heat dissipation channel 105, so that when the air guiding mechanism 22 is in the refrigeration position, the partitioning part 222 conducts the air outlet 103 and the cold air duct 1042, disconnects the air outlet 103 and the hot air duct 1041, and the air guiding part 223 is in a contracted state (see Figure 3 ) to conduct the hot air duct 1041 and the heat dissipation channel 105 for heat dissipation; when the air guiding mechanism 22 is in the heating position, the partitioning part 222 disconnects the air outlet 103 and the cold air duct 1042, conducts the air outlet 103 and the hot air duct 1041, and the air guiding part 223 is in an extended state (see Figure 5)Disconnect the hot air duct 1041 from the heat dissipation channel 105 so that the hot air blows towards the user.

[0043] Preferably, the driving mechanism in this embodiment is a driving motor or a solenoid valve. The air guiding part 223 is a telescopic air guiding plate made of plastic, and the air supply assembly 23 is an axial flow fan.

[0044] As Figure 1 and Figure 6-7 shown, further, it further includes a partition plate 3. The range hood main body 1 is also provided with a cold air dissipation channel 106. The two ends of the cold air dissipation channel 106 are respectively communicated with the cold air duct 1042 and the flue 101. The partition plate 3 is movably arranged in the cold air duct 1042 to control the on-off of the cold air duct 1042 and the cold air dissipation channel 106. The air guiding mechanism 22 is provided with a pushing block 2201 capable of pushing the partition plate 3 to move. The pushing block 2201 is arranged on the partition part 222 and its orientation is opposite to that of the pull rod 221. Thus, when the air guiding mechanism 22 is in the heating position, the pushing block 2201 can push the partition plate 3 to move upward to make the cold air duct 1042 communicate with the cold air dissipation channel 106, so that the cold air sequentially passes through the cold air dissipation channel 106 and the flue 101 for cold air dissipation; when the air guiding mechanism 22 is in the cooling position, the pushing block 2201 moves away from the partition plate 3, and the partition plate 3 moves downward to reset under its own gravity, so that the cold air duct 1042 is disconnected from the cold air dissipation channel 106, so that the cold air blows towards the user through the air outlet 103.

[0045] As Figure 7 shown, preferably, two vertically arranged chutes 108 are arranged side by side at intervals on the inner side wall of the cold air duct 1042. The two chutes 108 are respectively located on the opposite outer sides of the entrance of the cold air dissipation channel 106. The partition plate 3 is slidably mounted on the chutes 108. In other embodiments, the partition plate 3 can also be mounted on the inner side wall of the cold air duct 1042 by means of hinge.

[0046] More preferably, the number of the cold air dissipation channels 106 is two, and the two cold air dissipation channels 106 are respectively arranged on the left and right outer sides of the box body 11. The number of the partition plates 3 and the pushing blocks 2201 also corresponds to two. The two partition plates 3 are respectively slidably arranged on the left and right inner side walls of the cold air duct 1042, and the two pushing blocks 2201 are arranged on the opposite sides of the partition part 222 at positions corresponding to the partition plates 3. Thus, through the cooperation of the two cold air dissipation channels 106, the two partition plates 3 and the two pushing blocks 2201, the cold air dissipation area is effectively increased and the cold air dissipation effect is improved.

[0047] Further, it further includes a filtering device (not shown in the figure). The filtering device is arranged at the air inlet 102 to prevent pollutants such as dust from entering the air duct 104 through the air inlet 102.

[0048] As Figure 2As shown in FIGS. 3 or 4, further, it further includes a first temperature detection device 4 for detecting the inlet air temperature in real time. The first temperature detection device 4 is arranged at the air inlet 102 or at a position of the air duct 104 close to the air inlet 102. The control component is electrically connected to the first temperature detection device 4 and is used to adjust the working power of the refrigeration and heating device 2 according to the preset temperature and / or the inlet air temperature. In this embodiment, the first temperature detection device 4 is arranged at a position of the air duct 104 close to the air inlet 102, that is, at the upper end of the air duct 104 inside the box body 11.

[0049] Further, it further includes a second temperature detection device (not shown in the figure) for detecting the kitchen environment temperature in real time. The second temperature detection device is arranged on the range hood main body 1 and is electrically connected to the control component. The control component can adjust the working power of the refrigeration and heating device 2 according to at least the preset temperature, the inlet air temperature and the kitchen environment temperature, so as to ensure that the hot air or cold air blown to the user is the temperature set by the user.

[0050] The following combines Figure 2-5 to illustrate the working principle of the range hood air conditioner in this embodiment:

[0051] As Figure 2-3 shown, when refrigeration and heat dissipation are required, when the control component controls the air guiding mechanism 22 to be in the refrigeration position through the driving mechanism, at this time, the partition part 222 of the air guiding mechanism 22 conducts the cold air duct 1042 and the air outlet 103, disconnects the hot air duct 1041 and the air outlet 103, and the air guiding part 223 of the air guiding mechanism 22 is in a contracted state and conducts the hot air duct 1041 and the heat dissipation channel 105. The partition plate 3 resets under its own gravity and disconnects the cold air duct 1042 and the cold air dissipation channel 106. The refrigeration and heating component 21 works to generate cold air and hot air. The cold air is blown to the user through the air outlet 103 by the air supply component 23, realizing providing cold air for the user, while the hot air is sucked into the flue 101 through the heat dissipation channel 105 under the action of the range hood fan component, realizing heat dissipation for the refrigeration and heating component 21.

[0052] As Figure 4-5 shown, when heating and cold dissipation are required, when the control component controls the air guiding mechanism 22 to be in the heating position through the driving mechanism, at this time, the partition part 222 of the air guiding mechanism 22 disconnects the cold air duct 1042 and the air outlet 103, conducts the hot air duct 1041 and the air outlet 103, and the air guiding part 223 of the air guiding mechanism 22 is in an extended state and cuts off the hot air duct 1041 and the heat dissipation channel 105. The partition plate 3 slides upward under the pushing action of the push block 2201 and conducts the cold air duct 1042 and the cold air dissipation channel 106. The refrigeration and heating component 21 works to generate cold air and hot air. The hot air is blown to the user through the air outlet 103 by the air supply component 23, realizing providing hot air for the user, while the cold air is sucked into the flue 101 through the cold air dissipation channel 106 under the action of the range hood fan component, realizing cold dissipation for the refrigeration and heating component 21.

[0053] Embodiment 2

[0054] As Figure 8 shown, a control method for a range hood air conditioner, which is applied to a range hood air conditioner as described in Embodiment 1. Since the structure of the range hood air conditioner has been described in detail, specifically and clearly in Embodiment 1, it will not be elaborated here. The control method includes the following steps:

[0055] S1: Start the air conditioner function; Specifically, there is an air conditioner function key on the control component. After the user presses the air conditioner function key, the air conditioner function is started.

[0056] S2: Determine whether to enter the cooling and heat dissipation mode. If so, control the air guiding mechanism 22 of the refrigeration and heating device 2 to be in the cooling position and enter step S3. If not, control the air guiding mechanism 22 of the refrigeration and heating device 2 to be in the heating position and enter step S3;

[0057] S3: Obtain temperature parameters, where the temperature parameters include a preset temperature or / and an inlet air temperature;

[0058] S4: Control the working state of the refrigeration and heating device 2 according to the obtained temperature parameters.

[0059] It can be seen that by controlling the air guiding mechanism 22 to be in the cooling position or the heating position, the range hood air conditioner is realized to switch between the cooling and heat dissipation mode and the heating and cooling mode, and by controlling the working state of the refrigeration and heating device 2 according to the temperature parameters, it is effectively ensured that the hot air or cold air blown to the user is the temperature set by the user, improving the kitchen environment and enhancing the user experience.

[0060] Preferably, in step S2, for the determination of whether to enter the cooling and heat dissipation mode, it is determined by judging whether the user sets the cooling function. If so, enter the cooling and heat dissipation mode, control the air guiding mechanism 22 of the refrigeration and heating device 2 to be in the cooling position and enter step S3; if not, enter the heating and cooling mode, control the air guiding mechanism 22 of the refrigeration and heating device 2 to be in the heating position and enter step S3. Thus, the manual control of the range hood air conditioner to provide cold air or hot air is realized.

[0061] Preferably, in step S2, for the determination of whether to enter the cooling and heat dissipation mode, it can also be determined by comparing the inlet air temperature or the ambient temperature with [minimum value, maximum value]. If the inlet air temperature or the ambient temperature is less than or equal to the minimum value, enter the heating and cooling mode, control the air guiding mechanism 22 of the refrigeration and heating device 2 to be in the heating position and enter step S3; if the inlet air temperature or the ambient temperature is greater than or equal to the maximum value, enter the cooling and heat dissipation mode, control the air guiding mechanism 22 of the refrigeration and heating device 2 to be in the cooling position and enter step S3. Thus, the automatic control of the range hood air conditioner to provide cold air or hot air is realized, improving the product intelligence.

[0062] In addition, when the intake air temperature or the ambient temperature ∈ (minimum value, maximum value), the user can set the refrigeration function according to actual needs. If so, enter the refrigeration and heat dissipation mode; if not, enter the heating and heat dissipation mode.

[0063] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
