Technical Field

[0001] The utility model relates to the field of range hoods, and in particular to a thin smokeless pipe range hood with a high- and low-voltage electrostatic purification module and a mounting structure thereof. Background Art

[0002] The smokeless internal circulation range hood is a new type of range hood with two functions: internal circulation and purification. Internal circulation is to circulate the oil smoke indoors through certain technical means, thereby reducing dependence on outdoor air. Purification is to filter the oil smoke multiple times through efficient purification technology, and finally effectively remove the harmful substances in it, which can improve the air quality in the kitchen and reduce pollution to the outdoor environment.

[0003] Existing smokeless duct range hoods usually use high and low voltage electrostatic fields to purify oil smoke. The high and low voltage electrostatic fields are installed in a box and the box is then installed above the smoke hood. Therefore, this type of smokeless duct range hood is relatively high and low, and is difficult to install in a kitchen with a relatively narrow space. Therefore, there is an existing thin smokeless duct range hood that reduces the size of the range hood by directly installing the high and low voltage electrostatic fields in the smoke hood. However, how to reasonably design the installation position and installation method of the high and low voltage electrostatic fields in the smoke hood while ensuring the purification effect on the oil smoke so that the volume of the smoke hood is as small as possible is a problem that this type of thin smokeless duct range hood needs to solve. Utility Model Content

[0004] The purpose of the utility model is to provide a thin smokeless duct range hood with a high and low voltage electrostatic purification module and its mounting structure. The module and its mounting structure divide the internal space of the smoke hood by a partition and place the electrostatic field components on both sides of the partition, thereby ensuring the purification effect of the electrostatic field components while reasonably planning the installation position of the electrostatic field components to reduce the volume of the smoke hood.

[0007] In the above technical solution, preferably, a plurality of mounting holes are opened on the lower side of the smoke hood, and the mounting bracket is inserted and fits over the mounting holes and is detachably fixed to the lower side of the smoke hood.

[0008] In the above technical solution, preferably, a power supply module is provided on the smoke hood and the partition, and the ends of the two conductive rods of the electrostatic field element are inserted into the power supply module and the electrostatic field element is powered by the power supply module.

[0010] In the above technical solution, preferably, a compression spring is sleeved on the lower end of the conductive contact.

[0012] Compared with the prior art, the utility model has the following advantages and effects:

[0013] The utility model uses a partition and an electrostatic field element to divide the smoke hood into an air inlet chamber, an air outlet chamber and a transition chamber located at the front side.

At the same time, by arranging the partition, the electrostatic field elements are placed side by side on the left and right, which can make the structure inside the smoke hood more compact, thereby reducing the front and rear width required for the smoke hood, and is suitable for kitchens with relatively narrow space, thereby realizing a reasonable design of the position of the electrostatic field elements in the smoke hood.

DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-Figure 4 The present embodiment is a thin smokeless duct range hood with a high and low voltage electrostatic purification module and its mounting structure, comprising a smoke hood 1, a plurality of electrostatic field components 2 and a mounting bracket 3, wherein the electrostatic field components 2 are arranged in the left and right directions and the plurality of electrostatic field components 2 are placed side by side in the cavity of the smoke hood 1 of the range hood, a partition 4 is arranged in the front and back directions in the smoke hood 1, the upper side, the lower side and the rear side of the partition 4 are all in contact with the inner wall of the smoke hood 1, the plurality of electrostatic field components 2 are arranged on the left and right sides of the partition 4, the air outlet 11 and the air inlet 12 of the smoke hood 1 are respectively located on the left and right sides of the partition 4 and the air outlet 11 and the air inlet 12 are both located on the rear side of the electrostatic field component 2, the mounting bracket 3 is arranged in the smoke hood 1, and the electrostatic field component 2 is fixed on the mounting bracket 3.

[0021] Existing smokeless internal circulation oil fume purification integrated machines usually have an exhaust device (such as a fan) installed in the machine body to suck the oil fume from the air inlet 12 of the machine body, which is a conventional technical means in the field. In the utility model, the exhaust device is installed at the air outlet 11 of the smoke hood 1, and the oil fume is discharged through the exhaust device after purification, which can reduce the pollution of the exhaust device by the oil fume.

[0022] When the utility model is used, the oil smoke enters the cavity on the right side of the partition 4 through the air inlet 12 and moves forward through the electrostatic field element 2 on the right side of the partition 4, then the oil smoke bypasses the partition 4 and passes through the electrostatic field element 2 on the left side of the partition 4 to enter the cavity on the left side of the partition 4, and finally is discharged through the air outlet 11. Therefore, the utility model uses the partition 4 and the electrostatic field element 2 to divide the smoke hood 1 into three cavities, namely the air inlet chamber 14, the air outlet chamber 16 and the transition chamber 15 located on the front side. The oil smoke passes through the air inlet chamber 14, the transition chamber 16 and the transition chamber 15 in sequence. The transition chamber 15 and the air outlet chamber 16 purify the oil fume twice through the electrostatic field elements 2 at two positions, between the air inlet chamber 14 and the transition chamber 15 and between the transition chamber 15 and the air outlet chamber 16, thereby improving the purification effect of the electrostatic field elements 2; at the same time, by setting the partition 4, the electrostatic field elements 2 are placed side by side on the left and right, which can make the internal structure of the smoke hood 1 more compact, thereby reducing the front and rear width required for the smoke hood 1, which is suitable for kitchens with relatively narrow space, and realizes the reasonable design of the position of the electrostatic field elements 2 in the smoke hood 1.

[0023] See also Figure 2 , Figure 3 A plurality of mounting holes 13 are provided on the lower side of the smoke hood 1 , and the mounting bracket 3 is inserted and fits over the mounting holes 13 , and the mounting bracket 3 is detachably fixed on the lower side of the smoke hood 1 .

[0024] The electrostatic field element 2 is installed by fixing the electrostatic field element 2 to the upper end of each mounting bracket 3 one by one, then inserting the electrostatic field element 2 and the mounting bracket 3 upward into the mounting hole 13 as a whole and fixing the lower end of the mounting bracket 3 to the lower side of the smoke hood 1; when removing the electrostatic field element 2, the mounting bracket 3 is removed from the smoke hood 1 and pulled downward to remove the electrostatic field element 2 from the smoke hood 1, so that the electrostatic field element 2 can be removed for cleaning and maintenance after being used for a period of time.

[0025] See also Figure 1 A power supply module 5 is provided on the smoke hood 1 and the partition 4, and the ends of the two conductive rods 21 of the electrostatic field component 2 are inserted into the power supply module 5 and the electrostatic field component 2 is powered by the power supply module 5.

[0026] In the present invention, a control module 6 for controlling the range hood is arranged in the front side of the smoke collecting hood 1 .

[0027] When the electrostatic field element 2 is installed in the smoke hood 1 through the mounting bracket 3, the two conductive rods 21 on the electrostatic field element 2 are electrically connected to the power supply module 5 to realize power supply to the electrostatic field element 2. Therefore, in the utility model, the control module 6 of the range hood can be electrically connected to the power supply module 5 in advance. When the electrostatic field element 2 is installed in the smoke hood 1, the electrostatic field element 2 can be conveniently controlled by the control module 6, thereby facilitating the use of the utility model. At the same time, the position of the power supply module 5 is adapted to the position of the electrostatic field element 2 after installation. The power supply module 5 can also play a positioning role in the installation of the electrostatic field element 2, thereby facilitating the installation of the electrostatic field element 2 and reducing the probability of the electrostatic field element 2 being skewed during installation.

[0028] See also Figure 4 The power supply module 5 includes a base 51 and a conductive contact 52. The base 51 is fixed on the smoke hood 1 or the partition 4. Two vertical slide grooves 53 are provided on the base 51. The lower end of the slide groove 53 is provided with an opening 54. Two conductive contacts 52 are provided and are respectively located at the top of the two slide grooves 53.

[0029] When the electrostatic field component 2 is inserted upward into the smoke hood 1, the ends of the two conductive rods 21 on one side of the electrostatic field component 2 can be inserted into the slide groove 53 through the buckles at the lower end of the slide groove 53 and move upward along the slide groove 53. When the mounting bracket 3 is fixed to the smoke hood 1, the two conductive rods 21 of the electrostatic field component 2 are respectively in contact with the two conductive contacts 52 to achieve electrical connection, thereby guiding the installation of the electrostatic field component 2 through the slide groove 53. At the same time, the conductive rods 21 of the electrostatic field component 2 inserted into the slide groove 53 can play a certain fixing role on the electrostatic field component 2, thereby improving the stability of the electrostatic field component 2 fixed in the smoke hood 1.

[0030] See also Figure 4 The lower end of the conductive contact 52 is sleeved with a compression spring 55.

[0031] The compression spring 55 can play a buffering role when the conductive rod 21 of the electrostatic field device 2 moves upward and contacts the conductive contact 52, thereby avoiding the probability of the electrostatic field device 2 moving too fast and causing the conductive rod 21 and the conductive contact 52 to collide and be damaged, thereby improving the safety of the utility model during installation.

[0032] See also Figure 4 The lower opening 54 of the slide groove 53 is in an inverted funnel shape.

[0033] The inverted funnel-shaped opening 54 can guide the process of inserting the conductive rod 21 of the electrostatic field element 2 into the slide groove 53 , thereby facilitating the installation of the electrostatic field element 2 .

Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
