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

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0040] 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.
[0041] Example 1
[0042] Figure 1-Figure 5 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.
[0043] 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 described in detail 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 on the top of the refrigeration range hood and is used to discharge the heat emitted by the condenser.
[0044] 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 .
[0045] 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 usually provided with a display screen 111 for displaying the status information of the range hood. 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-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.
[0046] 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.
[0047] 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. 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. In order to ensure that the cold air has a sufficient air outlet range in the left and right directions, the cold air outlet 112 on the vertical wall 11 of the smoke hood 1 is a strip-shaped opening extending in the left and right directions, and correspondingly, the windshield 2 is a strip-shaped plate extending left and right.
[0048] The windshield 2 of this embodiment is driven by a connecting rod movement mechanism to move relative to the main body of the smoke hood 11. The connecting rod movement mechanism includes a first drive motor 201 and a first connecting rod 21 assembly, and the first connecting rod 21 assembly includes a first connecting rod 21 and a second connecting rod 22. The first connecting rod 21 and the second connecting rod 22 are parallel and arranged in sequence in the vertical direction. Figure 5 As shown, the first connecting rod 21 is located above the second connecting rod 22, and the first driving motor 201 is arranged on the main body of the smoke hood 1, and its power output shaft is drivingly connected to the first end of the first connecting rod 21. The second end of the first connecting rod 21 is rotationally connected to the back of the windshield 2, the first end of the second connecting rod 22 is rotationally connected to the main body of the smoke hood 1, and the second end of the second connecting rod 22 is rotationally connected to the windshield 2. A parallelogram connecting rod mechanism is formed between the first connecting rod 21, the second connecting rod 22 and the windshield 2, and when the first driving motor 201 rotates forward and reversely, it can drive the first connecting rod 21 to rotate around its first end, thereby realizing that the windshield 2 can move upward or downward smoothly.
[0049] A display screen 111 is also provided on the vertical wall 11 of the smoke collecting hood 1. The cold air outlet 112 of this embodiment is located above the display screen 111. The wind shield 2 can open the cold air outlet 112 by moving upward, and can close the cold air outlet 112 by moving downward.
[0050] 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 first drive motor 201 of the present embodiment is electrically connected to the control system of the range hood. The control system controls the first drive motor 201 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).
[0051] When the refrigeration function of the refrigeration range hood is not turned on, the connecting rod movement mechanism can block the cold air outlet 112 on the smoke hood 1 with the wind shield 2, 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 connecting rod movement mechanism can deviate the wind shield 2 from the cold air outlet 112 on the smoke hood 1 and open the cold air outlet 112. 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 when cooking, which improves the user experience.
[0052] Example 2
[0053] Figure 6-Figure 10Another preferred embodiment of the refrigeration range hood of the utility model is shown. The difference between this embodiment and embodiment 1 is that the upper and lower positions of the cold air outlet 112 on the vertical wall 11 of the fume hood 1 are different from the display screen 111. Specifically, in this embodiment, the cold air outlet 112 on the vertical wall 11 of the fume hood 1 is located below the display screen 111. The windshield 2 can open the cold air outlet 112 by moving downward, and can close the cold air outlet 112 by moving upward. Correspondingly, Fig.10 As shown, the first connecting rod 21 is located below the second connecting rod 22 , and the first driving motor 201 is also correspondingly arranged on the main body of the smoke hood 1 adjacent to the first connecting rod 21 , and its power output shaft is drivingly connected to the first end of the first connecting rod 21 .

The difference between this embodiment and the second embodiment is that the movement mode of the windshield 2 and the connecting rod movement mechanism for driving the windshield 2 to move are different. Specifically, the connecting rod movement mechanism includes a second drive motor 202 and a second connecting rod 22 assembly. The second connecting rod 22 assembly includes a third connecting rod 23 and a fourth connecting rod 24. The first end of the third connecting rod 23 is connected to the first end of the fourth connecting rod 24. The second end of the third connecting rod 23 and the second end of the fourth connecting rod 24 are respectively connected to the upper and lower areas of the windshield 2 so that the third connecting rod 23, the fourth connecting rod 24 and the windshield 2 form a triangular structure. The power output shaft of the second drive motor 202 is connected to the first end of the third connecting rod 23, and drives the second connecting rod 22 assembly and the windshield 2 to rotate upward or downward relative to the main body of the smoke hood 1. Fig.13 As shown, when the wind shield 2 is in the state of closing the cold air outlet 112, the wind shield 2 is in a vertically extended state, that is, it is located in front of the vertical wall 11 of the smoke hood 1 and is basically parallel to the vertical wall 11; when the wind shield 2 is in the state of opening the cold air outlet 112, the wind shield 2 is located in front of the inclined wall 12 and is parallel to the inclined wall 12.
[0056] The second drive motor 202 of the present embodiment is also electrically connected to the control system of the range hood. The control system controls the first drive motor 201 to drive the wind shield 2 to move and open or close the cold air outlet 112 according to the status signal of the range hood (such as whether the range hood is in the cooking state, or a temperature signal light corresponding to the temperature sensor of the kitchen environment provided on the range hood).
