Description

Technical Field

[0001] The utility model relates to the field of range hoods, in particular to a chassis structure of a detachable smokeless duct range hood. Background Art

[0002] In modern life, the kitchen is one of the most important rooms in the dining room. However, with the continuous development of cooking technology, the fumes and odors generated in the kitchen are becoming more and more serious. These fumes and odors will not only affect our health, but also our quality of life. Therefore, the kitchen is basically equipped with a range hood to discharge the fumes and odors to the outside through a pipe connected to the outside. However, this traditional range hood is not suitable for scenes where the exhaust pipe is difficult to install. For example, the catering industry often has problems such as long exhaust pipes and high costs, and high exhaust pressure during peak hours when there are many businesses. At the same time, directly discharging fumes into the atmosphere will also pollute the environment and affect nearby residents.

[0003] In response to the above problems, there is a type of smokeless duct range hood on the market. The fan continuously circulates the oil smoke in the range hood to absorb and discharge it into the room, and uses the filter device in the range hood to absorb and purify the oil smoke, so as to achieve the purpose of purifying the oil smoke and make the indoor air fresher. Since this type of range hood does not need to install an exhaust pipe and does not discharge oil smoke to the outside, it is widely used in the catering industry. However, since the smokeless duct range hoods used in the existing catering industry are large in size and the chassis is integrated, the range hood is easily restricted by the size of the kitchen entrance when it is moved to the kitchen for installation.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] See also Figure 1-Figure 6 The chassis structure of the detachable smokeless duct range hood of this embodiment includes a cover body 1 and a shell body 2. The cover body 1 and the shell body 2 are both hollow structures. The cover body 1 is provided with openings at both upper and lower ends. The shell body 2 is provided with an air inlet 21 and an air outlet 22. The lower end of the shell body 2 is adapted to fit and mount in the upper opening 12 of the cover body 1, and the air inlet 21 is connected to the upper opening 12 of the cover body 1.

[0024] The utility model installs a filter device 6 and a fan 7 in the cavity of the shell 2. Since the cavity of the shell 2 and the cavity of the cover body 1 are connected through the air inlet 21 and the upper opening 12, a negative pressure is formed in the shell 2 and the cover body 1 through the fan 7. Therefore, when cooking below the cover body 1 generates oil smoke, the oil smoke can be sucked into the cavity of the shell 2 by the lower opening 11 of the cover body 1 and enter the cavity of the shell 2 to be purified by the filter device 6. Finally, the purified air is discharged back into the room through the air outlet 22, thereby achieving the oil smoke purification effect of the smokeless duct range hood. Since the shell body 2 in the utility model is mounted in the upper opening 12 of the cover body 1, and the upper opening 12 of the cover body 1 is closed by the lower end of the shell body 2, it is ensured that the oil smoke in the cover body 1 can all enter the shell body 2 through the air inlet 21. Therefore, when installing the utility model, the cover body 1 can be first installed and fixed above the cooking area, and then the shell body 2 can be mounted in the upper opening 12 of the cover body 1, so that the cover body 1 and the shell body 2 can be carried separately, reducing the obstacles to the installation of the range hood when the kitchen entrance is small, and it is also more labor-saving to carry them separately, which improves the convenience of the utility model during installation.

[0025] See also Figure 2 , Figure 3 , Figure 4A support plate 13 is arranged inside the cover body 1. The support plate 13 is inclined with a higher front end and a lower rear end. A plurality of oil leakage holes 14 are arranged on the rear end of the support plate 13. An oil groove 15 is arranged at the bottom end of the rear side of the cover body 1. The oil groove 15 is located below the oil outlet hole. An oil outlet 16 with a valve connected to the oil groove 15 is arranged on one side of the cover body 1.

[0026] The oil fume separator 8 is a kind of oil fume separator 10, and the oil fume separator 10 ...

[0027] See also Figure 3 A plurality of hooks 5 are provided at the upper end of the cover body 1.

[0028] The cover body 1 is hoisted in the kitchen through the hook 5 and the screw mounting hole on the rear side of the cover body 1, which reduces the difficulty of installation of the present invention.

[0029] See also Figure 6 A sliding frame 23 for installing the filtering device 6 is arranged in the shell 2, and an installation opening 24 is opened on the front end surface of the shell 2. The installation opening 24 is located on the front side of the sliding frame 23. A control panel 3 is detachably arranged on the shell 2 at the installation opening 24, and the control panel 3 covers the installation opening 24.

[0030] The filter device 6 used in the existing smokeless duct range hood usually includes activated carbon adsorption plates, high and low voltage electrostatic field components, and UV photocatalyst catalytic components. The filter device 6 needs to be removed for cleaning or replacement after being used for a period of time. Therefore, the existing integrated chassis will make it inconvenient to remove and install the filter device 6.

[0031] In the present invention, the filter device 6 is slidably inserted into the sliding frame 23 through the installation opening 24, and the installation opening 24 is sealed by the control panel 3. At the same time, the control panel 3 and the housing 2 clamp the front and rear ends of the filter device 6 to fix the filter device 6, thereby simultaneously realizing the installation of the filter device 6 and the control panel 3. When removing the filter device 6, the control panel 3 is first removed, and then the filter device 6 is taken out. Therefore, the present invention can conveniently install and disassemble the filter device 6, which is convenient for later maintenance work. And when the range hood is installed in the kitchen, the cover body 1, the housing 2, the filter device 6 and the control panel 3 can be installed in sequence, avoiding the problem that the filter device 6 is installed in the housing 2 in advance, resulting in the housing 2 being too heavy and inconvenient to lift, thereby reducing the difficulty of installation.

[0032] See also Figure 5 , Figure 6 The left end of the control panel 3 is hingedly connected to the housing 2, and the right end of the control panel 3 is fixedly connected to the housing 2 by a hand screw 4.

[0033] The installation opening 24 is exposed by unscrewing the hand screw 4 and rotating the control panel 3, thereby facilitating installation and removal of the filter device 6 through the installation opening 24, simplifying the removal steps of the control panel 3 and reducing the complexity of the installation and removal operations of the filter device 6.

[0034] See also Figure 5 The air inlet 21 is arranged on the left side of the lower end surface of the shell 2, and the air outlet 22 is arranged on the right side of the front end surface of the shell 2.

[0035] Since the filter device 6 is installed in the middle position of the shell 2, and the air inlet 21 and the air outlet 22 are located on both sides of the filter device 6, it is ensured that the air mixed with oil fume gas moves from one side of the filter device 6 to the other side, thereby ensuring that the oil fume gas therein can be fully purified in the filter device 6, thereby improving the purification effect of the filter device 6 on oil fume.

[0036] See also Figure 6 A hanging plate 25 is detachably fixed on the front end surface of the shell 2, and the hanging plate 25 is fixed to the shell 2 by hand screws 4. The air outlet 22 is opened on the hanging plate 25, and a threaded hole 26 for installing the fan 7 is opened on the hanging plate 25 at the air outlet 22.

[0037] The fan 7 is arranged in the air outlet 22 to reduce the probability of direct contact between the fan 7 and the oil smoke, thereby reducing the rate at which the fan 7 is contaminated by the oil smoke and reducing the cleaning frequency of the fan 7. The hanging plate 25 is detachably fixed to the housing 2 by hand screws 4, which is convenient for the user to install the fan 7 and remove the hanging plate 25 to disassemble, clean or repair the fan 7.
