Abstract
Description
Technical Field
[0001] The present invention relates to a fan, in particular to a fan with a heating module. Background Art
[0002] When people bathe in the bathroom, the use of hot water raises the air temperature. However, conventional bathroom exhaust fans simply exhaust the air. Because this exhausted air carries heat, a significant amount of heat is carried away along with the air during operation. Furthermore, the air flow creates wind, which can make people feel even cooler when standing beneath the exhaust fan. This wind, combined with the heat loss, can cause discomfort. Summary of the Invention
[0003] In order to overcome the disadvantage that the existing exhaust fan will take away the heat and generate wind when exhausting the bathroom air, which will cause discomfort to people, the present invention provides a fan with a heating module, including a fan housing and a fan body; the fan body is installed in the fan housing;
[0004] It also includes a heating element and a cover; a heating element is arranged on the upper part of the fan housing, and heat is radiated into the bathroom through the heating element to maintain the temperature of the bathroom; a cover is fixedly connected to the upper side of the fan housing, and the cover is arranged with a constricted upper portion.
[0005] As a preferred technical solution of the present invention, a bottom filter is also included, and the bottom filter is detachably connected to the lower side of the fan housing.
[0006] As a preferred technical solution of the present invention, it also includes a top filter screen, and the top filter screen is detachably connected to the upper side of the fan housing; a heating element is installed on the top filter screen.
[0007] As a preferred technical solution of the present invention, a mounting plate is provided at the bottom of the fan housing.
[0008] As a preferred technical solution of the present invention, it also includes an external air inlet duct and an internal air exhaust duct; the upper part of the cover shell is detachably connected to the external air inlet duct; the internal exhaust duct is fixedly connected to the internal side of the external air inlet duct through a number of connecting rods; a first one-way ventilation component is provided between the external air inlet duct and the internal exhaust duct, and wind can only pass through the first one-way ventilation component from top to bottom; a second one-way ventilation component is provided in the internal exhaust duct, and wind can only pass through the second one-way ventilation component from bottom to top.
[0009] As a preferred technical solution of the present invention, a third one-way ventilation component is provided between the external air inlet duct and the internal air exhaust duct, and the wind can only pass through the third one-way ventilation component from left to right.
[0010] As a preferred technical solution of the present invention, the left portion of the inner exhaust duct is arranged to be shorter than the left portion of the outer air inlet duct.
[0011] As a preferred technical solution of the present invention, it also includes a ventilation pipe and a filter screen; the ventilation pipe is fixedly connected to the left inner part of the external air inlet pipe through several connecting rods; the 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.
[0012] As a preferred technical solution of the present invention, the ventilation duct is 5 to 10 cm away from the inner exhaust duct, and the right radius of the ventilation duct is smaller than the inner diameter of the inner exhaust duct, so that the wind discharged from the inner exhaust duct will be partially transferred to the outside of the ventilation duct.
[0013] As a preferred technical solution of the present invention, the ventilation pipe is configured to expand on the left side.
[0014] The beneficial effects of the present invention are:
[0015] When exhausting bathroom air, the fan generates upward wind to achieve normal ventilation. If the fan's air causes discomfort due to the coolness of the air, the heating element is activated, radiating heat downward. Heat is then collected downward by the shrink housing, compensating for heat loss and maintaining a warm and comfortable bathroom temperature.
[0016] The present invention periodically controls the fan body to run in reverse to draw outside air into the bathroom, and uses the outside air to dry the fan body and the heating element. At the same time, the heating element is started to further generate hot air, which can dry the fan body more thoroughly, effectively avoiding the reduction in or damage to the exhaust fan's service life due to a humid environment, and extending the service life of various fan components.
[0017] The bottom and top filters of the present invention prevent debris from entering the fan housing, protecting the fan's internal structure. The additional filters intercept debris that enters when drawing in outside air. When the exhaust fan is operating, the cleverly designed ventilation duct and airflow pattern remove debris intercepted by the filters and debris on the left inner wall of the external air inlet duct, preventing debris from accumulating in the ventilation duct and ensuring the ventilation efficiency and normal operation of the exhaust fan.

DETAILED DESCRIPTION
[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Example 1: A fan with a heating module, such as Figure 1-7 As shown, the fan comprises a fan housing 1 and a fan body 2; the fan body 2 is mounted within the fan housing 1; a heating element 5 and a cover 6 are also included; a heating element 5 is mounted on the upper portion of the fan housing 1, radiating heat into the bathroom to maintain the bathroom temperature; a cover 6 is fixedly attached to the upper side of the fan housing 1, and the cover 6 is tapered at the top, which enhances downward heat transfer from the heating element 5. A bottom filter 3 is also included, which is removably connected to the bottom side of the fan housing 1. A top filter 4 is also included, which is removably connected to the top side of the fan housing 1; the heating element 5 is mounted on the top filter 4. A mounting plate 1a is provided at the bottom of the fan housing 1, and the present invention is mounted on the bathroom ceiling via the mounting plate 1a.
[0028] The present invention (the fan with a heating module is hereinafter referred to as an exhaust fan) is proposed to address the problem that existing exhaust fans exhaust bathroom air, which takes away heat and generates wind, causing discomfort to people.
[0029] When the present invention discharges the bathroom air to the outside, the fan body 2 generates wind from bottom to top, and the air in the bathroom is pumped toward the cover 6 and then discharged from the bathroom.
[0030] When people are bathing in the bathroom, in order to prevent the fan body 2 from discharging air and taking away heat while generating wind, which would cause discomfort to people, the heating element 5 can be controlled to generate heat and radiate downwards through the heating element 5 to fill the heat loss caused by the discharge of air to maintain the temperature of the bathroom, thereby avoiding people feeling uncomfortable. At the same time, the cover 6 with a narrowed upper portion can reduce the transfer of heat to the outside and improve the downward heat transfer of the heating element 5.
[0031] In the embodiment of the present invention, the heating element 5 may be a heating lamp, which provides heat by irradiating downwards.
[0032] The present invention prevents foreign matter from entering the fan housing 1 through the bottom filter 3 and the top filter 4 .
[0033] Example 2: Based on Example 1, Figure 1-7 As shown, it also includes an external air inlet duct 101 and an internal air exhaust duct 102, and the left ends of the external air inlet duct 101 and the internal air exhaust duct 102 are connected to the outside world; the upper part of the cover 6 is detachably connected to the external air inlet duct 101; the inner side of the external air inlet duct 101 is fixedly connected to the internal air exhaust duct 102 through a number of connecting rods; between the external air inlet duct 101 and the internal air exhaust duct 102, and in the direction close to the cover 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; in the internal exhaust duct 102, and in the direction close to the cover 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.
[0034] Based on Example 1, since the exhaust fan works in the bathroom, and the bathroom is a humid environment, the fan body 2 and the heating element 5 will be shortened in a humid environment for a long time, and the condensed water of the exhaust fan will suddenly drip downwards and cause people to feel uncomfortable. Based on this problem, the present invention can periodically control the fan body 2 to run in reverse, that is, to generate wind from top to bottom, and then draw the outside air into the bathroom through the channel between the external air inlet pipe 101 and the internal exhaust pipe 102. 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 the fan body 2 and the heating element 5 are dried by the outside air. Because the structure of the fan body 2 is more sophisticated, the heating element 5 can also be started to heat at this time, thereby generating downward hot air to dry the fan body 2 more thoroughly, thereby avoiding the reduction of the service life or damage of the exhaust fan due to the humid environment.
[0035] It should be noted that during normal bathroom air extraction, the air passes through the second one-way ventilation member 102a and is discharged from the inner exhaust duct 102. Furthermore, the radius of the inner exhaust duct 102 is smaller than the constriction of the housing 6, thus facilitating downward transfer of heat generated by the heating element 5 to supplement the heat removed by the bathroom air.
[0036] In the 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 one-way deformable thin plates, which is a prior art and will not be described in detail here.
[0037] Example 3: Based on Example 2, Figure 1-7 As shown, a third one-way ventilation element 101b is provided between the outer air inlet duct 101 and the inner air exhaust duct 102, away from the housing 6. Wind can only pass through the third one-way ventilation element 101b from left to right. The left portion of the inner exhaust duct 102 is shorter than the left portion of the outer air inlet duct 101. It also includes a ventilation duct 201 and a filter screen 202. The ventilation duct 201 is fixedly connected to the inner left portion of the outer air inlet duct 101 via a number of connecting rods. The filter screen 202 is fixedly connected to the left side of the ventilation duct 201, and the filter screen 202 is fixed to the outer air inlet duct 101. The ventilation duct 201 is 5 to 10 cm away from the inner exhaust duct 102, and the radius of the right portion of the ventilation duct 201 is smaller than the inner diameter of the inner exhaust duct 102. As a result, the air discharged from the inner exhaust duct 102 is partially diverted to the outside of the ventilation duct 201. The ventilation duct 201 is configured to expand on the left side.
[0038] In Example 2, since the exhaust fan needs to draw air from the outside into the bathroom, there is a possibility that debris outside the bathroom will be drawn into the exhaust fan. Based on this problem, the present invention intercepts the debris by setting a filter 202. At this time, the debris accumulates on the filter 202. When the present invention draws the air in the bathroom to the outside, the wind flows to the ventilation pipe 201 through the inner exhaust duct 102. Part of the wind passes through the inside of the ventilation pipe 201, and part of the wind passes through the outside of the ventilation pipe 201, thereby blowing away the debris intercepted on the filter 202. At the same time, the wind sent out from the outside of the ventilation pipe 201 is oblique, which can blow away the debris on the left inner wall of the outer air inlet duct 101. In this way, the present invention can prevent external debris from accumulating in the outer air inlet duct 101 and the inner exhaust duct 102, thereby ensuring the smooth flow of the pipeline.
[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
