Description

Technical Field

[0001] The present invention relates to a fan, and in particular to a fan with a heating module. Background Art

[0002] When people take a bath in the bathroom, the use of hot water will increase the air temperature in the bathroom. However, when the existing ordinary bathroom exhaust fan works, it simply discharges the air in the bathroom. Since the discharged air carries heat, a large amount of heat will be taken away along with the air during the operation of the exhaust fan. On the other hand, the flow of gas will generate wind. When a person stands under the exhaust fan, the wind blowing on the body will make people feel cooler. Coupled with the loss of heat, people will feel uncomfortable. Summary of the Invention

[0003] In order to overcome the disadvantages that the existing exhaust fan discharges the air in the bathroom, takes away heat and generates wind, bringing discomfort to people, the present invention provides a fan with a heating module, which includes a fan housing and a fan body; the fan body is installed in the fan housing; It further includes a heating element and a cover; a heating element is arranged in the upper part of the fan housing, and heat is radiated and supplemented into the bathroom through the heating element to maintain the bathroom temperature; a cover is fixedly connected to the upper side of the fan housing, and the cover is provided with a constricted upper part.

[0004] As a preferred technical solution of the present invention, it further includes a bottom filter screen, and the bottom filter screen is detachably connected to the lower side of the fan housing.

[0005] As a preferred technical solution of the present invention, it further includes a top filter screen, and the top filter screen is detachably connected to the upper side of the fan housing; the heating element is installed on the top filter screen.

[0006] As a preferred technical solution of the present invention, an installation plate is arranged at the bottom of the fan housing.

[0007] As a preferred technical solution of the present invention, it further includes an outer air inlet duct and an inner exhaust duct; the upper part of the cover is detachably connected to the outer air inlet duct; the inner exhaust duct is fixedly connected to the inner side of the outer air inlet duct through a plurality of connecting rods; a first one-way ventilation member is arranged between the outer air inlet duct and the inner exhaust duct, and the wind can only pass through the first one-way ventilation member from top to bottom; a second one-way ventilation member is arranged in the inner exhaust duct, and the wind can only pass through the second one-way ventilation member from bottom to top.

[0008] As a preferred technical solution of the present invention, a third one-way ventilation member is arranged between the outer air inlet duct and the inner exhaust duct, and the wind can only pass through the first one-way ventilation member from left to right.

[0009] As a preferred technical solution of the present invention, the left part of the inner exhaust duct is shorter than the left part of the outer air inlet duct.

[0010] As a preferred technical solution of the present invention, it further includes a ventilation pipe and a filter screen; a ventilation pipe is fixedly connected to the left part inside the external air inlet pipe through a plurality of connecting rods; a filter screen is fixedly connected to the left side of the ventilation pipe, and the filter screen is fixedly connected to the external air inlet pipe.

[0011] As a preferred technical solution of the present invention, the ventilation pipe is 5-10 cm away from the internal exhaust air pipe, and the radius of the right part of the ventilation pipe is smaller than the inner diameter of the internal exhaust air pipe. Thus, part of the air discharged from the internal exhaust air pipe will transfer to the outside of the ventilation pipe.

[0012] As a preferred technical solution of the present invention, the ventilation pipe is arranged with a flared left side.

[0013] The beneficial effects of the present invention are as follows: When the present invention discharges the bathroom air to the outside, normal exhaust ventilation is achieved by the fan body working to generate upward air flow. When a person feels uncomfortable due to the coolness caused by the suction and blowing of the fan, the heating element can be controlled to work. The heat generated by the heating element radiates downward, and at the same time, under the action of the reduced mask housing, it gathers downward to fill the heat loss and maintain the bathroom temperature, making people feel warm and comfortable during bathing.

[0014] By regularly controlling the fan body to run in the reverse direction, the present invention sucks and blows the outside air into the bathroom, uses the outside air to dry the fan body and the heating element, and at the same time starts the heating element to further generate hot air, which can more thoroughly dry the fan body, effectively avoiding the reduction in the service life or damage of the exhaust fan due to a humid environment, and extending the service life of each component of the fan.

[0015] The bottom filter screen and the top filter screen of the present invention can prevent sundries from entering the fan housing and protect the internal structure of the fan.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: A fan with a heating module, as Figures 1-7 shown, includes a fan housing 1 and a fan body 2; the fan body 2 is installed inside the fan housing 1; it further includes a heating element 5 and a cover 6; the heating element 5 is arranged at the upper part inside the fan housing 1, and heat is radiated and supplemented into the bathroom through the heating element 5 to maintain the bathroom temperature; the cover 6 is fixedly connected to the upper side of the fan housing 1, and the cover 6 is provided with a reduced opening at the upper part, and the downward heat transfer of the heating element 5 is enhanced through the reduced opening cover 6. It further includes a bottom filter screen 3, and the bottom filter screen 3 is detachably connected to the lower side of the fan housing 1. It further includes a top filter screen 4, and the top filter screen 4 is detachably connected to the upper side of the fan housing 1; the heating element 5 is installed on the top filter screen 4. The bottom of the fan housing 1 is provided with a mounting plate 1a, and the present invention is installed on the bathroom ceiling through the mounting plate 1a.

[0020] The present invention (the fan with a heating module is also simply referred to as an exhaust fan below) is proposed in view of the problem that the existing exhaust fan will take away heat and generate wind when discharging the bathroom air, bringing discomfort to people.

[0021] When the present invention discharges the bathroom air outwards, the fan body 2 works to generate an upward wind from bottom to top, and the air in the bathroom is pumped towards the cover 6 and then discharged from the bathroom.

[0022] When a person takes a bath in the bathroom, to avoid the discomfort caused by the wind generated while the fan body 2 discharges air and takes away heat; the heating element 5 can be controlled to work, generate heat through the heating element 5 and radiate downward, filling the heat loss caused by air discharge to maintain the bathroom temperature, thereby avoiding discomfort for people. At the same time, the upper constricted housing 6 can reduce the heat transfer to the outside world and improve the heat transfer of the heating element 5 downward.

[0023] In the embodiment of the present invention, the heating element 5 can be a heating lamp tube, and heat is provided by irradiating downward through the heating element 5.

[0024] The present invention avoids sundries from entering the fan housing 1 through the bottom filter screen 3 and the top filter screen 4.

[0025] Embodiment 2: On the basis of Embodiment 1, as Figures 1-7 shown, it further includes an outer air inlet pipe 101 and an inner air discharge pipe 102. The left ends of the outer air inlet pipe 101 and the inner air discharge pipe 102 are connected to the outside; the upper part of the housing 6 is detachably connected to the outer air inlet pipe 101; the inner air discharge pipe 102 is fixedly connected to the inner side of the outer air inlet pipe 101 through a plurality of connecting rods; between the outer air inlet pipe 101 and the inner air discharge pipe 102, and in the direction close to the housing 6, a first one-way ventilation member 101a is provided, and the wind can only pass through the first one-way ventilation member 101a from top to bottom; inside the inner air discharge pipe 102, and in the direction close to the housing 6, a second one-way ventilation member 102a is provided, and the wind can only pass through the second one-way ventilation member 102a from bottom to top.

[0026] On the basis of Embodiment 1, since the exhaust fan works in the bathroom, and the bathroom belongs to a humid environment, and the fan body 2 and the heating element 5 being in a humid environment for a long time will reduce their service life, and the condensed water of the exhaust fan dripping suddenly downward will also cause discomfort to people. Based on this problem, the present invention can regularly control the fan body 2 to run in reverse, that is, generate wind from top to bottom, and then through the channel between the outer air inlet pipe 101 and the inner air discharge pipe 102, draw the outside air into the bathroom. In this way, the air passes through the first one-way ventilation member 101a, and then the air blows to the fan body 2 and the heating element 5, and then dries the fan body 2 and the heating element 5 through the outside air. Also, because the structure of the fan body 2 is more precise, the heating element 5 can also be started to heat at this time, and then generate hot air downward to dry the fan body 2 more thoroughly, so as to avoid the reduction or damage of the service life of the exhaust fan caused by the humid environment.

[0027] It should be noted that when the present invention normally sucks and discharges the air in the bathroom, the air passes through the second one-way ventilation member 102a and discharges outward from the inner air discharge pipe 102. And the radius of the inner air discharge pipe 102 is relatively smaller than the constriction of the housing 6, so it is more conducive to the heat generated by the heating element 5 to be transferred downward to supplement the heat taken away by the bathroom air.

[0028] In an embodiment of the present invention, the first one-way ventilation member 101a and the second one-way ventilation member 102a are each composed of a plurality of thin plates with one-way deformation, which is the prior art and will not be elaborated here.

[0029] Embodiment 3: On the basis of Embodiment 2, as Figures 1-7 shown, between the outer air inlet pipe 101 and the inner air discharge pipe 102, and in the direction away from the housing 6, a third one-way ventilation member 101b is provided. The wind can only pass through the first one-way ventilation member 101a from left to right. The left part of the inner air discharge pipe 102 is set shorter than the left part of the outer air inlet pipe 101. It further includes a ventilation pipe 201 and a filter screen 202; the left part inside the outer air inlet pipe 101 is fixedly connected with the ventilation pipe 201 through a plurality of connecting rods; the left side of the ventilation pipe 201 is fixedly connected with the filter screen 202, and the filter screen 202 is fixedly connected with the outer air inlet pipe 101. The ventilation pipe 201 is 5 - 10 cm away from the inner air discharge pipe 102, and the radius of the right part of the ventilation pipe 201 is smaller than the inner diameter of the inner air discharge pipe 102. Thus, part of the wind discharged from the inner air discharge pipe 102 will transfer to the outside of the ventilation pipe 201. The ventilation pipe 201 is set to have a flared left side.

[0030] In Embodiment 2, since the exhaust fan needs to suck the outside air into the bathroom, there may be a situation where sundries outside the bathroom are sucked into the exhaust fan. Based on this problem, the present invention intercepts the sundries by setting the filter screen 202. At this time, the sundries accumulate at the filter screen 202. When the present invention pumps the air in the bathroom to the outside, the wind flows from the inner air discharge pipe 102 to the ventilation pipe 201. Part of the wind passes through the inside of the ventilation pipe 201, and part passes through the outside of the ventilation pipe 201, thereby blowing off the sundries intercepted on the filter screen 202. At the same time, the wind sent out from the outside of the ventilation pipe 201 is oblique, and thus can blow off the sundries on the inner wall of the left side of the outer air inlet pipe 101. In this way, the present invention can avoid the accumulation of external sundries in the outer air inlet pipe 101 and the inner air discharge pipe 102, ensuring the smoothness of the pipeline.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that these embodiments can be changed without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
