Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a refrigeration range hood. Background Art

[0002] The refrigeration range hood integrates the air conditioning component with the range hood, and the range hood shell is provided with an air conditioning outlet. The air conditioning range hood can work in multiple different modes. As long as the air conditioning mode is turned on, the air conditioning outlet will blow out cold or hot air, which can be blown directly to the cook or to the kitchen, thereby effectively improving the cook's cooking experience.

[0003] For example, the Chinese invention patent application with application number CN202321527202.2 (authorization announcement number: CN219976623U) discloses an air conditioner and a hood and air conditioner combination unit, in which both the refrigeration device and the heat dissipation device are arranged inside the kitchen, and the heat generated inside the heat dissipation device is blown into the exhaust pipe through the second fan, and discharged from the exhaust pipe to the outdoor environment, so as to discharge the heat generated inside the heat dissipation device during the operation of the air conditioner to the outdoors, so that the air conditioner can normally regulate the temperature of the kitchen environment. The air conditioner can also include a panel, and a panel return air port and a panel air outlet are opened on the panel, and the second air port is connected to the panel air outlet, and the cold air in the refrigeration shell after heat exchange with the evaporator is blown out from the air outlet, the second air port and the panel air outlet to the kitchen environment in sequence. The panel can shield the refrigeration device and the heat dissipation device to improve the decorative effect of the air conditioner. The panel can also be hinged with an air guide plate, which can guide the air outlet direction of the air conditioner to meet the user's demand for the air outlet direction.

[0004] However, the integrated kitchen air-conditioning range hood in the above patent application still has certain shortcomings. This type of range hood generally sets the air outlet on the upper edge of the cabinet door, so that the air outlet is embedded in the cabinet, which has better integrity and is relatively beautiful. However, due to the high air outlet and the angle, the cold air cannot reach or blows on the head when standing in front of the range hood, which makes the comfort poor. In addition, due to the long air outlet distance, the cold air effect is poor, which greatly reduces the user experience.

[0005] Therefore, the existing refrigeration range hoods need further improvement. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a refrigeration range hood which can take into account both the aesthetics of installation and the cooling effect in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the above technical problems is: a refrigeration range hood, comprising:

[0008] The oil fume suction device comprises a fume collecting hood and a fan system, wherein the fume collecting hood is provided with a fume inlet, and the fan system is in fluid communication with the fume inlet of the fume collecting hood;

[0009] The refrigeration device comprises a refrigeration module and a cold air outlet channel connected to the refrigeration module.

[0010] A cold air outlet connected to the air outlet channel is provided at the front side of the smoke collecting hood, and a wind shield which can move relative to the main body of the smoke collecting hood to open or close the cold air outlet is also provided at the cold air outlet;

[0011] An air-conditioning control button operation area electrically connected to the control system of the range hood is provided on the front side of the smoke collecting hood in the area adjacent to the cold air outlet. When the wind shield closes the cold air outlet, the wind shield simultaneously blocks the front side of the air-conditioning control button operation area. When the wind shield opens the cold air outlet, the wind shield simultaneously moves away from the air-conditioning control button operation area so that the air-conditioning control button operation area is exposed.

[0012] In order to ensure the cold air outlet range in the left and right directions, the cold air outlet is a strip-shaped opening extending along the left and right directions of the smoke hood, and the air conditioning control button operation area is located on the left or right side of the cold air outlet.

[0013] As an improvement, the air conditioning control button operation area is configured as a touch button area or a mechanical button area.

[0014] In order to prevent the opening and closing of the wind shield from affecting the range hood function control operation of the range hood, a range hood control button operation area electrically connected to the range hood control system is provided on the front side of the smoke hood corresponding to the bottom of the cold air outlet.

[0015] In order to facilitate users to turn on and off the refrigeration function, an air conditioning control switch button is also provided on the front side of the smoke collecting hood corresponding to the lower part of the cold air outlet.

[0016] As an improvement, the wind shield is arranged on the smoke hood in a manner that it can move up and down relative to the main body of the smoke hood, and when the wind shield opens the cold air outlet, the wind shield is located above the cold air outlet. It is conceivable that the wind shield can also be installed on the main body of the smoke hood in a fixed-axis rotation or non-fixed-axis rotation manner.

[0017] Taking into account the installation height of the smoke hood of the range hood, in order to adapt to it, the height of the cold air outlet from the ground after installation is about 1.5m to 1.65m. The front side wall of the smoke hood includes a vertical wall extending vertically and an inclined wall extending obliquely backward and downward from the bottom of the vertical wall. The smoke inlet is provided on the inclined wall, and the cold air outlet and the air conditioning control button operation area are both arranged on the vertical wall.

[0018] In order to improve the smoke collection effect and reduce the escape of oil smoke, it also includes a smoke baffle which is rotatably arranged on the main body of the smoke collecting hood and can open and close the smoke inlet.

[0019] In order to achieve the purpose of automatically opening and closing the cold air outlet according to the state of the range hood, it also includes a driving device for driving the wind shield to move relative to the main body of the smoke hood. The driving device is electrically connected to the control system of the range hood, and the control system controls the driving device to move the wind shield according to the state signal of the range hood to open or close the cold air outlet.

[0020] As an improvement, the fan system and the refrigeration module are both arranged on the top of the smoke hood.

[0021] Compared with the prior art, the utility model has the following advantages: the cold air outlet is set on the front side of the smoke hood. Since the height of the smoke hood (generally about 1.5m to 1.65m above the ground) is relatively suitable, the user can feel the cold air effect more directly during cooking, which improves the user experience. When the refrigeration function of the refrigeration range hood is turned on, the wind shield deviates from the cold air outlet on the smoke hood, and the cold air outlet can be opened. Since the air conditioning control button operation area is also arranged adjacent to the cold air outlet, when the wind shield opens the cold air outlet, the air conditioning control button operation area is also exposed at the same time, which is convenient for the user to adjust the function. When the refrigeration function of the refrigeration range hood is not turned on, the wind shield can simultaneously block the cold air outlet on the smoke hood and the air conditioning control button operation area, so that the front appearance of the smoke hood is more coordinated and consistent, ensuring aesthetics.

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0030] Figure 1-Figure 6 A preferred embodiment of the refrigeration range hood of the utility model is shown. The refrigeration range hood includes a fume suction device, a refrigeration device and a heat dissipation device 3. The fume suction device includes a fan system 15, a fume hood 1 and a shell 16 connected to the top of the fume hood 1. The fan system 15 is arranged in the shell 16. The fan system 15 generally adopts a centrifugal fan for sucking and exhausting oil fume. The sucked smoke can be discharged from the smoke outlet 14 at the top. A smoke inlet 13 is provided on the fume hood 1. For example, the fume hood 1 of a conventional top-suction range hood has a smoke inlet 13 at the bottom, and the fume hood 1 of a close-suction range hood has a smoke inlet 13 on the front side wall. The fume hood 1 of the refrigeration range hood of this embodiment adopts a fume hood structure similar to that of a close-suction range hood, which will be described in detail below.

[0031] The above-mentioned refrigeration device and heat dissipation device constitute the air conditioner indoor device for realizing the refrigeration function of the refrigeration range hood. The refrigeration device includes a refrigeration module 17, which can be located on the right (left) side of the refrigeration range hood. It generally includes a compressor, a condenser and an evaporator. The compressor, the condenser and the evaporator are connected through a refrigerant pipeline. The working principle of the refrigeration module is the same as that of the existing air conditioner, which will not be repeated here. The refrigeration device has a cold air outlet channel 18, and the evaporator is usually arranged in the cold air outlet channel 18. The heat dissipation device 3 is generally a heat dissipation fan, which is located at the top of the refrigeration range hood and is used to discharge the heat emitted by the condenser.

[0032] The bottom of the smoke collecting hood 1 is also provided with an oil cup 4 extending left and right, for collecting the oil dripping from the smoke collecting hood 1 .

[0033] The front side wall of the smoke hood 1 of the range hood device includes a vertical wall 11 extending vertically and an inclined wall 12 extending obliquely backward and downward from the bottom of the vertical wall 11. The vertical wall 11 is relatively short in upper and lower dimensions, and is provided with a range hood control button operation area 114 for users to control the functions of the range hood, wherein the range hood control button operation area 114 can be a touch button area or a mechanical button area. The inclined wall 12 is relatively large in size, and is provided with a smoke inlet 13. In order to improve the smoke collection effect and reduce the escape of oil smoke, the smoke hood 1 is also provided with a smoke baffle 19 that can rotate relative to the main body of the smoke hood 1. Generally, the smoke baffle 19 is connected to the smoke hood 1 by a hinge, and extends in the left and right direction relative to the rotation axis of the smoke hood 1, and can open and close the smoke inlet 13 during the rotation process. The rotating connection mechanism and working process of the smoke baffle 19 are both existing technologies and will not be repeated here.

[0034] The vertical wall 11 of the smoke hood 1 of this embodiment is also provided with a cold air outlet 112, which is connected to the cold air outlet channel 18 of the refrigeration device and is used to discharge cold air into the outlet. Considering that the height position of the vertical wall 11 of the smoke hood 1 (generally about 1.5m to 1.65m above the ground) is relatively suitable, the cold air outlet 112 at this height position discharges air forward, and the user can directly feel the cold air effect during cooking, thereby improving the user's experience.

[0035] In order to ensure that the cold air has a sufficient outlet range in the left and right directions, the cold air outlet 112 on the vertical wall 11 of the smoke hood 1 of this embodiment is a strip opening extending in the left and right directions, wherein the cold air outlet 112 is located above the range hood control button operation area 114.

[0036] See also Figure 1The front side of the smoke collecting hood 1 is correspondingly provided with an air conditioning control switch button 114 below the cold air outlet 1, and the air conditioning control switch button 114 is arranged adjacent to the range hood control button operation area 114. The air conditioning control switch button 114 is electrically connected to the control system of the range hood and is used to control the opening and closing of the air conditioning indoor device.

[0037] The cold air outlet 112 of the smoke hood 1 is also provided with a windshield 2 that can move relative to the main body of the smoke hood 1. Corresponding to the above-mentioned strip-shaped cold air outlet 112, the windshield 2 is a strip-shaped plate extending left and right. The windshield 2 has an open state of opening the cold air outlet 112 and a closed state of shielding the cold air outlet 112 as its position relative to the main body of the smoke hood 1 changes. The left and right dimensions of the windshield 2 are larger than the left and right dimensions of the cold air outlet 112, and are basically consistent with the left and right dimensions of the smoke hood 1.

[0038] The windshield plate 2 of this embodiment is slidably disposed on the main body of the smoke hood 1 in such a manner that it can move up and down relative to the main body of the smoke hood 1. Specifically, Figure 5 The back structure of the windshield 2 of this embodiment is shown. The back of the windshield 2 is connected to the main body of the smoke hood 1 through a vertically extending slide rail assembly 20, thereby ensuring the stability of the windshield 2 moving up and down.

[0039] The windshield 2 is driven up and down by a driving device, specifically, the driving device includes a driving motor (not shown) and a gear rack transmission assembly, the gear rack transmission assembly includes a transmission rack 22 vertically arranged on the back of the windshield 2 and a gear 23 meshing with the transmission rack 22, and the gear 23 is connected to the output shaft of the driving motor. When the driving motor rotates forward and reverse, the power is transmitted to the rack through the gear 23, thereby driving the windshield 2 to move up or down. Specifically, the cold air outlet 112 of this embodiment is located above the display screen 111. The windshield 2 can open the cold air outlet 112 by moving upward, and can close the cold air outlet 112 by moving downward.

[0040] Combination Figure 1 and Figure 2 The front side of the smoke hood 1 is also provided with an air conditioning control button operation area 113 which is electrically connected to the control system of the range hood in the area adjacent to the cold air outlet 112. Specifically, Figure 2As shown, the air conditioning control button operation area 113 is located on the right side of the cold air outlet 112. When the wind shield 2 closes the cold air outlet 112, the wind shield 2 also blocks the front side of the air conditioning control button operation area 113, so that the cold air outlet 112 and the air conditioning control button operation area 113 are not visible on the front side, thereby improving the overall aesthetics of the range hood. When the refrigeration function of the refrigeration range hood is turned on, the wind shield 2 moves upward under the drive device to open the cold air outlet 112. In this state, the wind shield 2 is located above the cold air outlet 112, and the air conditioning control button operation area 113 is also exposed, which is convenient for users to adjust the air conditioning function.

[0041] See also Figure 6 In order to limit the upper and lower limit positions of the windshield 2, the back of the windshield 2 is also provided with a limit post extending backward near its lower edge. When the windshield 2 moves upward to open the cold air outlet 112, the limit post 21 can cooperate with the corresponding limit structure on the main body of the smoke hood 1 in the upper and lower directions to prevent the windshield 2 from moving excessively upward.

[0042] In order to achieve the purpose of automatically opening and closing the cold air outlet 112 according to the state of the range hood, the driving motor of this embodiment is electrically connected to the control system of the range hood. The control system controls the driving device to drive the wind shield 2 to move and open or close the cold air outlet 112 according to the state signal of the range hood (such as whether the range hood is in the cooking state, or the temperature signal light corresponding to the range hood for identifying the kitchen environment temperature sensor).

[0043] When the wind shield 2 opens the cold air outlet 112 , the front wall of the wind shield 2 is flush with the front wall of the main part of the vertical wall 11 of the smoke hood 1 , thereby making the front side wall of the smoke hood 1 more coordinated and improving the aesthetics.

[0044] When the refrigeration function of the refrigeration range hood is not turned on, the wind shield 2 can cover the cold air outlet 112 on the smoke hood 1, so that the front side appearance of the smoke hood 1 is more coordinated and consistent, ensuring aesthetics. When the refrigeration function of the refrigeration range hood is turned on, the wind shield 2 can be deviated from the cold air outlet 112 on the smoke hood 1, and the cold air outlet 112 is opened. Since the cold air outlet 112 is set at the front side of the smoke hood 1, its height position (generally about 1.5m to 1.65m above the ground) is relatively suitable, and the user can feel the cold air effect more directly during cooking operations, which improves the user experience.
