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 cold air outlet channel is provided on the front side of the smoke collecting hood, and an air guide hood that can rotate relative to the main body of the smoke collecting hood is also provided at the cold air outlet. An air guide port is provided on the air guide hood, and the air guide hood has an open state in which the cold air outlet is opened and the air guide port is connected to the cold air outlet, and a closed state in which the cold air outlet is blocked as its rotation position changes.

[0011] In order to adjust the state of the air guide cover, the air guide cover is rotated with a straight line extending left and right as a rotation axis to connect the cold air outlet of the smoke collecting hood.

[0012] In order to ensure the 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 guide hood is also correspondingly long and strip-shaped, and the two ends of the air guide hood in the length direction are rotatably connected to the left and right sides of the cold air outlet.

[0013] Generally speaking, the rotation of the air guide hood can be manually operated by the user or driven by a drive motor. Preferably, in order to achieve automatic adjustment of the air guide hood, a drive motor is also included to drive the air guide hood to rotate. The drive motor is electrically connected to the control system of the range hood, and the control system controls the drive motor to drive the air guide hood to move and open or close the cold air outlet according to the status signal of the range hood.

[0014] In order to drive the air guide hood to rotate, one end of the cold air outlet of the smoke hood is provided with a positioning shaft extending toward the cold air outlet, and the end of the air guide hood adjacent to the positioning shaft has a positioning hole for the positioning shaft to rotate and limit therein, and the other end of the cold air outlet of the smoke hood is provided with a driving shaft extending toward the cold air outlet, and the end of the air guide hood adjacent to the driving shaft has a socket for the driving shaft to be inserted therein, the driving shaft is transmission-connected to the output shaft of the driving motor, and can be driven by the driving motor to rotate around its own axis, thereby driving the air guide hood to rotate.

[0015] In order to hide the driving motor and ensure the overall aesthetics, the driving motor is arranged in the smoke hood, the driving shaft is connected to the output shaft of the driving motor, and a clearance opening is provided on the end side wall of the cold air outlet of the smoke hood for the driving shaft to extend from the smoke hood into the cold air outlet.

[0016] In order to ensure the rotation stability of the air guide hood, the air guide hood includes at least two air guide ports arranged in sequence along the left and right directions, and two adjacent air guide ports are connected by support columns extending left and right. A vertically extending support plate is also provided at a position corresponding to each of the support columns in the cold air outlet of the smoke collecting hood, and the support plate has a rotating shaft hole for the corresponding support column to pass through along the left and right directions and to be able to rotate and limit therein.

[0017] As an improvement, the air guide cover includes a base plate and a U-shaped plate which is U-shaped as a whole, and two ends of the U-shaped plate are connected to the base plate to jointly define the air guide port.

[0018] As an improvement, there are at least two U-shaped plates, and the U-shaped plates are arranged in sequence and spaced apart along the length direction of the base plate.

[0019] 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 is arranged on the vertical wall.

[0020] In order to reasonably arrange the spatial positions of the display screen and the cold air outlet, a display screen for displaying status information of the range hood is also provided on the vertical wall of the smoke hood, and the cold air outlet is located above, below, on the left or on the right side of the display screen.

[0021] In order to reduce the speed of cold air flowing out of the air guide port and improve the blowing comfort of the user, the opening size of the air guide port of the air guide cover gradually increases along the air flow direction.

[0022] Compared with the prior art, the utility model has the following advantages: when the refrigeration function of the refrigeration range hood is not turned on, the wind shield can be flipped to block the cold air outlet of the smoke hood, so that the front appearance of the smoke hood is more coordinated and consistent, ensuring aesthetics. When the refrigeration function of the refrigeration range hood is turned on, the air guide hood can be deflected to open the cold air outlet, and the air guide port is connected to the cold air outlet. Since the cold air outlet is arranged on the front side of the smoke hood, 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.

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] 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.

[0036] Figure 1-Figure 11 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 4. 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.

[0037] The refrigeration device includes a refrigeration module, which can be located on the left or right side of the top of the smoke hood. The above-mentioned housing for placing the fan system can be made small and arranged side by side with the refrigeration module on the top of the smoke hood 1. The refrigeration module generally includes a compressor 171, a condenser 173 and an evaporator (not shown). The compressor 171, the condenser 173 and the evaporator are connected by a refrigerant pipeline. The working principle of the refrigeration module is the same as that of the existing air conditioner and will not be described in detail here. The refrigeration device has a cold air outlet channel 18 connected to the cold air fan 172. The evaporator is usually arranged in the cold air outlet channel 18 or at the inlet of the cold air fan to cool the air. The heat dissipation device 4 includes a heat dissipation fan 41, which is located at the top of the smoke hood and is used to discharge the heat emitted by the condenser.

[0038] The front side wall of the smoke collecting 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 115 for displaying the status information of the range hood, while the inclined wall 12 is relatively large in size, and is provided with a smoke inlet 13. The display screen 115 of this embodiment can be a single display screen used only to display the status information of the range hood (including the working status information of the range hood and the status information of the refrigeration function), or can be a touch screen with a touch adjustment function (that is, electrically connected to the control system of the range hood). In order to improve the smoke collection effect and reduce the escape of oil smoke, the smoke collecting hood 1 is also provided with a smoke baffle 19 that can rotate relative to the main body of the smoke collecting hood 1. Generally, the smoke baffle 19 is connected to the smoke collecting hood 1 by a hinge, and extends in the left-right direction relative to the rotation axis of the smoke collecting 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 prior arts and will not be described in detail here.

[0039] The vertical wall 11 of the smoke hood 1 of this embodiment is also provided with a cold air outlet 111, which is connected to the cold air outlet channel 18 of the refrigeration device and is used to discharge cold air into the room. 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 111 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.

[0040] The cold air outlet 111 may be located above the display screen 115. Figure 1-6 The cold air outlet 111 may also be located below the display screen 115, as shown. Figure 7 Of course, there can be two display screens 115, which are respectively arranged on the left and right sides of the cold air outlet 111, such as Figure 8 shown.

[0041] The cold air outlet 111 of the smoke hood 1 of this embodiment is also provided with an air guide hood 2 that can rotate relative to the main body of the smoke hood 1 around an axis extending left and right. The air guide hood 2 has an open state of opening the cold air outlet 111 and a closed state of blocking the cold air outlet 111 as its rotation position 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 111 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 air guide hood 2 is a long strip extending left and right.

[0042] The air guide hood 2 of this embodiment is driven to rotate by the driving motor 3. One end of the cold air outlet 111 of the smoke hood 1 is provided with a positioning shaft 114 extending toward the cold air outlet 111, and the end of the air guide hood 2 adjacent to the positioning shaft 114 has a positioning hole 25 for the positioning shaft 114 to rotate and limit therein. The other end of the cold air outlet 111 of the smoke hood 1 is provided with a driving shaft 31 extending toward the cold air outlet 111, and the end of the air guide hood 2 adjacent to the driving shaft 31 has a socket 24 for the driving shaft 31 to be inserted therein, wherein the driving shaft 31 and the socket 24 are both non-circular, thereby achieving the purpose of torque transmission. The driving shaft 31 is connected to the output shaft of the driving motor 3 arranged in the smoke hood 1, and can be driven by the driving motor 3 to rotate around its own axis, thereby driving the air guide hood 2 to rotate. More specifically, the driving shaft 31 can adopt an axially hollow sleeve structure, so as to be sleeved and connected to the output shaft of the driving motor 3. The end side wall of the cold air outlet 111 of the smoke collecting hood 1 is also provided with a clearance hole 112 , which allows the driving shaft 31 to extend from the smoke collecting hood 1 into the cold air outlet 111 and then be inserted into the insertion hole 24 of the air guide hood 2 .

[0043] The driving motor 3 of this embodiment is electrically connected to the control system of the range hood, and the control system controls the driving motor 3 to drive the air guide cover 2 to move and open or close the cold air outlet 111 according to the state signal of the range hood. The "state signal of the range hood" can refer to the on / off signal of the refrigeration switch button of the range hood, or it can be a temperature signal detected by a sensor component integrated on the range hood, such as a temperature sensor. If the temperature sensor detects that the indoor temperature is greater than the set temperature, the refrigeration function is started, and at the same time, the driving motor 3 is controlled to drive the air guide cover 2 to open the cold air outlet 111.

[0044] The air guide cover 2 includes a base plate 21 and a U-shaped plate 22 which is U-shaped as a whole. The base plate 21 is in the shape of a long strip, and the two ends of the U-shaped plate 22 are connected to the base plate 21 to define the air guide port 20 together. In order to ensure the uniformity of the air outlet, a corresponding partition plate can also be provided in the air guide port 20 to form a plurality of sub-air guide ports 20. The air guide cover 2 has at least two U-shaped plates 22, each of which is arranged in sequence along the length direction of the base plate 21, and the two adjacent U-shaped plates 22 are connected by support columns 23 extending left and right, thereby forming at least two air guide ports 20 arranged in sequence along the left and right directions on the air guide cover 2. In order to ensure the rotation stability of the air guide cover 2, a vertically extending support plate 113 is further provided in the cold air outlet 111 of the smoke collecting cover 1 at a position corresponding to each support column 23, and a rotating shaft hole 1130 is provided in the front of the supporting plate 113, and the axis of the rotating shaft hole 1130 extends in the left and right directions and is located on the same axis as the axis of the positioning shaft 114 and the driving shaft 31 mentioned above. The front edge of the support vertical plate 113 also has an installation opening that penetrates the shaft hole 1130 backwards. The support column 23 of the air guide cover 2 can be installed into the shaft hole 1130 from front to back through the installation opening and rotated to be limited therein.

[0045] See also Figure 5 and Figure 6 When the air duct 2 is in the state of closing the cold air outlet 111, the base plate 21 of the air duct 2 faces outward, while the U-shaped plate 22 faces inward. In order to avoid interference with other components during the rotation of the air duct 2, the width of the base plate 21 of the air duct 2 of this embodiment is greater than the width of the U-shaped plate 22, wherein the width of the base plate 21 matches the width of the cold air outlet 111. When the air duct 2 is in the closed state, the base plate 21 of the air duct 2 can just cover the cold air outlet 111, thereby ensuring the overall aesthetics of the range hood. In addition, the opening size of the air duct 20 of this embodiment (such as Figure 6 The upper and lower dimensions d) of the air guide port 20 shown in the figure gradually increase along the air flow direction, thereby reducing the outlet speed of the cold air flowing out of the air guide port 20 and improving the blowing comfort of the user.

[0046] When the air guide hood 2 is in the state of opening the cold air outlet 111, the extension direction of the air guide port 20 of the air guide hood 2 is basically arranged horizontally. Preferably, the front edge of the base plate 21 can be slightly tilted upward, so that the cold air outlet direction can be slightly tilted upward, bringing comfortable cool breeze to the user while avoiding interference with oil smoke.

[0047] 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 .

[0048] The "fluid communication" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part respectively), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, conduit, guide member, hole, groove, etc., or a chamber allowing fluid to flow through, or a combination of the above.
