Description

Technical Field

[0001] The present application relates to the technical field of ventilation equipment, and specifically discloses an indoor ventilation equipment. Background Art

[0002] Ventilation equipment is mainly used for the exchange of indoor and outdoor air, sending fresh air from the outside into the room to replace the dirty air in the room. Ventilation equipment not only has the function of accelerating air circulation, but also can control the temperature and humidity of the supplied gas through the heat exchange plate installed inside.

[0003] The ventilation equipment used in residential areas usually includes the following structure: a ventilation main body, an air intake pipe connected to the ventilation main body and used to supply outside air, an air supply pipe connected to the ventilation main body and used to discharge new ventilation air into the house, and a heat exchange plate installed in the air supply pipe. A fan blade mechanism driven by a motor as a power element is installed in the ventilation main body. The fan blade mechanism cooperates with the air intake pipe to introduce outside air, and after filtering, it is sent into the house through the air supply pipe.

[0004] In the prior art, most ventilation bodies use the holes opened on their own shells as the source of external gas supply, and no longer connect to the air intake duct separately, and install the air filtration structure in the air supply duct. During long-term use, the dust entrained by the external air will not only adhere to the air filtration structure, but also adhere to the fan blades of the fan blade mechanism.

[0005] Therefore, in view of this, the inventor provides an indoor ventilation device to solve the above-mentioned problem. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that in the ventilation main body structure used in traditional ventilation equipment, during the ventilation process, the air filtering structure is placed behind the ventilation main body structure, so that the dust in the air will not only adhere to the air filtering structure, but also adhere to the fan blade mechanism of the ventilation main body.

[0007] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides an indoor ventilation device, including a ventilation main body arranged outside one side wall, an air intake pipe arranged on the wall surface of the side adjacent to the ventilation main body, and an air supply pipe arranged on the inside of the ventilation main body and used to supply air to the room, a ventilation component for air intake is arranged in the ventilation main body, a heat exchange plate is arranged in the air supply pipe, a guardrail with a plurality of holes is arranged at the bottom end of the air intake pipe, an air filter structure is also slidably connected in the air intake pipe above the guardrail, and a dust discharge outlet for the air filter structure to slide out is arranged on the side of the air intake pipe close to the room.

[0008] Furthermore, an inner inclined surface is integrally formed inwardly on the outer side of the bottom of the air intake duct, connecting the bottom end surface of the bottom channel and the outer end surface.

[0009] Furthermore, an air inlet extending to the top of the inner inclined surface is opened at the bottom of the air inlet duct, and the baffle covers the air inlet.

[0010] Furthermore, the holes on the guardrail are all elliptical through holes.

[0011] Furthermore, each of the railings below the holes is fixedly connected with a water guide platform, and the top end surface of the water guide platform is concave inwards and forms an arc surface for rainwater to flow into the hole.

[0012] Furthermore, the air filtering structure includes a rectangular frame slidably connected to the inner wall of the air intake duct, a sealing plate fixed to the rectangular frame and clamped to the dust discharge port, and a plurality of filter screens fixed in the rectangular frame and capable of covering the inner chamber of the air intake duct.

[0013] Furthermore, the filter screens are distributed in a staggered manner within the frame, and adjacent staggered filter screens can completely cover the inner chamber of the air intake duct.

[0014] The principle and effect of this scheme are:

[0015] 1. Compared with the prior art, the utility model uses a ventilation component to introduce external air through the home pipes and suck it into the air supply pipe, controls the temperature and humidity through the heat exchange plate in the air supply pipe, and filters the dust in the air through the guardrail and the air filter structure above, thereby solving the problem that the main ventilation structure used in traditional ventilation equipment has the problem that during the ventilation process, the dust in the air will not only adhere to the air filter structure, but also to the fan blade mechanism of the ventilation body because the air filter structure is placed behind the main ventilation structure.

[0016] 2. Compared with the prior art, the baffle of the utility model is arranged at the bottom of the air intake duct, and no debris will fall into the air intake duct. During non-working period, it can also reduce the amount of external air entering and reduce the accumulation of dust.

[0017] 3. Compared with the prior art, the air filter structure of the utility model is connected to the air intake duct by sliding. After long-term operation, the dust accumulated in the air filter structure can be cleaned by sliding the air filter structure out of the air intake duct, which is more convenient and quick.

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] The figure marks in the drawings of the specification include: wall 1, glass 2, air supply pipe 3, shell 4, adapter box 5, top channel 6, bellows 7, air guide box 8, fixing rod 9, fan blades 10, guardrail 11, bottom channel 12, filter 13, water guide platform 14, heat exchange plate 15, and drive motor 16.

[0025] A indoor ventilation device, for example Figure 1 As shown:

[0026] It includes a ventilation body, an air intake pipe installed on a wall surface adjacent to the ventilation body, and an air supply pipe 3 installed inside the ventilation body. The utility model is applied to indoor ventilation. In this embodiment, a chamber for installing the air supply pipe 3 is opened on the wall 1 above the window sill. The air supply pipe 3 is installed in the chamber, the ventilation body is installed on the outside of the wall 1, and the air intake pipe is installed on the outer wall of the wall 1 on the left side. The indoor and outdoor environments are separated by glass 2 at the window sill.

[0027] like Figure 2 and Figure 3 As shown, the ventilation body includes a shell 4, a rotating shaft bracket installed on the inner side of the left end of the shell 4, and a fan blade 10 mechanism installed in the shell 4 through the rotating shaft bracket. A transfer box 5 connected to the shell 4 is also installed at the left end of the shell 4, and two fixing rods 9 are respectively welded to the top of the shell 4, and the shell 4 is a cylindrical shell 4. The fan blade 10 mechanism includes a driven rotating shaft installed on the rotating shaft bracket and rotatable, and a fan blade 10 circumferentially fixedly installed on the driven rotating shaft. A fixing bracket is installed above the wall 1 to connect and fix the fixing rod 9 by bolts to stabilize the shell 4.

[0028] The air supply pipe 3 is installed at the left end of the shell 4 through a transition box, and is connected to the shell 4 through the transition box. In this embodiment, the air supply pipe 3 is rectangular, and the two ends of the transition box wrap the air supply pipe 3 and the end of the shell 4 respectively. A motor bracket is installed at the right end of the air supply pipe 3, and a drive motor 16 is installed through the motor bracket. The output shaft of the drive motor 16 is connected to the driven shaft through a coupling. The motor bracket wraps to the outside of the motor and fits the inner wall of the air supply pipe 3. A heat exchange plate 15 and a honeycomb mesh plate are also installed inside the air supply pipe 3 to reduce noise.

[0029] Inside the air supply pipe 3, on the top surface of the indoor wall 1, there is also an air guide box 8. The left end of the air guide box 8 is connected to the end of the air supply pipe 3, and a plurality of exhaust grooves are horizontally opened inside the air guide box 8. A connecting air chamber connecting the air supply pipe 3 and the exhaust grooves is also opened inside the air guide box 8.

[0030] like Figure 3 As shown, the air intake duct includes a top channel 6, a middle channel and a bottom channel 12 which are connected sequentially from top to bottom. The top channel 6 has an air outlet, and an air inlet is opened on the right side of the adapter box 5, and the air outlet and the air inlet are connected by a bellows 7.

[0031] The middle channel is a transition channel. The thicknesses of the top channel 6 , the middle channel and the bottom channel 12 are equal. However, the width of the top channel 6 is longer than that of the bottom channel 12 , and the length of the top channel 6 is shorter than that of the bottom channel 12 .

[0032] At the bottom end of the bottom channel 12, an air inlet is opened, and the outer side of the bottom end of the bottom channel 12 is integrally formed with an inclined surface inward to form an inner inclined surface connecting the bottom end surface of the bottom channel 12 and the outer end surface. The air inlet extends from the bottom end of the bottom channel 12 to the inner inclined surface, and the air inlet is completely covered by a guardrail 11, and a plurality of elliptical through holes are opened on the guardrail 11. The guardrail 11 located on the inner inclined surface is also integrally formed with a plurality of water guide platforms 14 respectively located on the outer side of the bottom end of the circular through holes. The top end surface of the water guide platform 14 is concave inward and forms an arc surface for rainwater to flow into the elliptical through holes.

[0033] A dust outlet is also provided on the left wall of the bottom channel 12 above the air inlet, and two transverse grooves are provided on the corresponding inner wall of the bottom channel 12. An air filter structure is installed in the bottom channel 12 through the dust outlet and the transverse grooves. The air filter structure includes a rectangular frame, a sealing plate installed on the left side of the rectangular frame, and a plurality of filters 13 installed in the rectangular frame. The sealing plate can completely close the dust outlet, and a key is integrally formed on the inner side of the sealing plate. A slot for the key to be inserted is provided at the dust outlet. The rectangular frame is fixed by the connection between the key and the slot. A pull ring is also installed on the left side of the sealing plate, which facilitates the pulling out of the frame. Each filter 13 completely covers the internal chamber of the bottom channel 12, and connecting rods for fixing the filter 13 are respectively welded on the front and rear sides of the rectangular frame.

[0034] In this embodiment, the installed filters 13 are staggered in the frame, and every two staggered filters 13 can completely cover the inner chamber of the bottom channel 12. Moreover, the installed bottom channel 12, the middle channel and the top channel 6 are all close to the window sill, and the bottom channel 12, the middle channel and the top channel 6 are fixed to the outer wall of the wall 1 by bolts.

[0035] When the utility model is used, the driven shaft is driven to rotate by the driving motor 16, which drives the fan blades 10 to rotate to introduce the outside air through the air inlet and suck it into the air supply pipe 3. The temperature and humidity are regulated by the heat exchange plate 15 in the air supply pipe 3, and the dust in the air is filtered by the baffle 11 at the air inlet and the filter 13 above.

[0036] Moreover, in this embodiment, the air inlet opened by the bottom channel 12 is located at the bottom. After the outside air is introduced into the bottom channel 12 from the air inlet, the dust carried by it will accumulate on the filter screen 13 of the air filtering structure, instead of flowing into the filter screen 13 with the air flow or falling inward from the filter screen 13 as when the air inlet is opened horizontally or at the top.

[0037] Furthermore, the guardrail 11 used is also provided with a water guide platform 14. When it rains, the rainwater flowing down can be guided to the inner end surface through the arc surface on the water guide platform 14, and flow out along the guardrail 11 at the bottom to clean the guardrail 11. Furthermore, the guardrail 11 is provided at the bottom to prevent the outside from falling in and entering;

[0038] Furthermore, by arranging an air filter structure near the window, it is convenient to pull out the frame through the pull ring and clean the filter 13 installed in the frame, and the staggered filter 13 structure makes the rising airflow staggered, thereby increasing the dust removal rate.

[0039] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
