Detailed Description
Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.
The hand dryer 100 according to the embodiment of the present utility model is described below with reference to the accompanying drawings. As shown in fig. 1 to 6, the hand dryer 100 according to the embodiment of the present utility model includes a housing and a blower.
The housing has a passage 5 passing therethrough in the up-down direction. The shell also comprises an air outlet 3, and the air outlet 3 is arranged at the bottom of the shell. The fan is arranged in the shell, and the outlet of the fan is communicated with the air outlet 3.
In the related art, a single-sided air-out hand dryer is mostly in a cubic shape, and an air outlet is arranged below the single-sided air-out hand dryer. Because the cube shape shields light, the light of the hands of a user is darker, the moisture drying condition of the hands of the user is difficult to observe, and certain inconvenience is caused to use; meanwhile, the light of the ground below the installation projection surface of the appliance is darker due to shielding, so that the overall aesthetic degree of the bathroom is affected.
The bottom of the hand dryer 100 according to the embodiment of the present utility model is provided with the air outlet 3, so that the air flow formed by the blower can be discharged downwards from the air outlet 3 and dry the hands of the user. The shell is provided with the channel 5 penetrating the shell along the up-down direction, so that light can penetrate through the channel 5 to irradiate hands of a user positioned below the bottom of the shell, comfort of the user in use is improved, drying is convenient to observe, the bottom below the bottom of the shell is brighter, and brightness of a surrounding environment is improved.
The air outlet 3 below the bottom of the casing can cause the air flow at the bottom of the casing to flow at the time of air discharge, so that the air flow below the bottom of the casing is fast in velocity and small in pressure (air pressure), so that the passage 5 and the air above the passage 5 can flow toward the region where the pressure is small (bottom of the casing). And the channel 5 runs through the shell along the up-down direction, and the air outlet 3 is arranged at the bottom of the shell, so that the flow direction of the channel 5 and the air above the channel 5 is downward, and the air is convenient to flow downward (under the action of gravity), so that the channel 5 and the air above the channel 5 can dry the hands of a user together with the air discharged from the air outlet 3. That is, the hand dryer 100 according to the embodiment of the present utility model can make the air flow of the hand dryer 100 for drying the hands of the user larger when the air outlet 3 is exhausted by providing the passage 5 penetrating the hand dryer in the up-down direction and providing the air outlet 3 at the bottom of the housing, thereby facilitating the rapid drying of the hands of the user.
Accordingly, the hand dryer 100 according to the embodiment of the present utility model has advantages of high comfort in use, rapid drying, and improved brightness of the surrounding environment.
As shown in fig. 1 to 6, the hand dryer 100 according to the embodiment of the present utility model includes a housing and a blower.
The housing has a passage 5 passing therethrough in the up-down direction. The housing is annular and the inner annular surface of the housing defines a channel 5. Specifically, the housing includes an inner housing 1 and an outer housing 2, both of which are annular housings, the outer housing 2 being fitted around the outer peripheral side of the inner housing 1. The inner wall surface of the inner housing 1 forms an inner annular surface of the housing and defines a passage 5. For example, the inner case 1 may be a doughnut-shaped case, an elongated doughnut-shaped case (short side is arc-shaped), a rectangular doughnut-shaped case, and a polygonal doughnut-shaped case.
As shown in fig. 2 to 6, in some embodiments, the projected outer peripheral contour of the passage 5 is the same shape as the projected outer peripheral contour of the outer peripheral surface of the housing in a cross section perpendicular to the up-down direction. On a cross section perpendicular to the up-down direction, the projected outer peripheral contour of the passage 5 is the projected inner peripheral contour of the inner wall surface of the inner case 1, and the projected outer peripheral contour of the outer peripheral surface of the case is the projected outer peripheral surface of the outer case 2. That is, the shape of the inner case 1 is the same as the shape of the outer case 2. For example, the inner case 1 and the outer case 2 are both circular cases or rectangular annular cases. The up-down direction is shown by the arrow in the figure.
In some embodiments, in a cross section perpendicular to the up-down direction, the area ratio of the projected area of the passage 5 to the projected area of the outer peripheral surface of the housing is 1: (2-3). That is, in a cross section perpendicular to the up-down direction, the area ratio of the projected area of the inner wall surface of the inner case 1 to the projected area of the outer peripheral surface of the outer case 2 is 1: (2-3). For example, in a cross section perpendicular to the up-down direction, the area ratio of the projected area of the passage 5 to the projected area of the outer peripheral surface of the housing is 1:2.5.
as shown in fig. 2-6, in some embodiments, the projected peripheral profile of the channel 5 includes, in a cross-section perpendicular to the up-down direction, a first edge 51, a second edge 52, a third edge 53, and a fourth edge 54 that are connected in sequence. The first edge 51 and the third edge 53 are disposed opposite to each other in a first horizontal direction, and the second edge 52 and the fourth edge 54 are disposed opposite to each other in a second horizontal direction, the first horizontal direction being perpendicular to the second horizontal direction, and a length of each of the first edge 51 and the third edge 53 being equal to or greater than a length of each of the second edge 52 and the fourth edge 54. The first horizontal direction may be a front-rear direction, and the second horizontal direction may be a left-right direction. The front-rear direction and the left-right direction are indicated by arrows in the figure.
For example, the inner case 1 includes a first panel 11, a second panel 12, a third panel 13, and a fourth panel 14 connected in this order, and each panel of the inner case 1 is arc-transitioned. The outer shell 2 comprises a first shell 21, a second shell 22, a third shell 23 and a fourth shell 24 which are connected in sequence, and each shell of the outer shell 2 has an arc transition. The first casing 21, the first panel 11, the third panel 13, and the third casing 23 are disposed in this order in the first horizontal direction (front to rear), and the second casing 22, the second panel 12, the fourth panel 14, and the fourth casing 24 are disposed in this order in the second horizontal direction (right to left). The lower edge of the first panel 11 is a first edge 51, the lower edge of the second panel 12 is a second edge 52, the lower edge of the third panel 13 is a third edge 53, and the lower edge of the fourth panel 14 is a fourth edge 54.
The shell also comprises an air outlet 3, and the air outlet 3 is arranged at the bottom of the shell. Specifically, the bottoms of the inner casing 1 and the outer casing 2 are connected by a bottom plate 25, and the air outlet 3 is formed on the bottom plate 25, and the thickness direction of the bottom plate 25 is the up-down direction. The number of the air outlets 3 is one or more.
As shown in fig. 1 to 6, in some embodiments, the air outlet 3 includes a plurality of sub-air outlets 3 disposed at intervals, so that the structural strength of the bottom plate 25 can be improved, and the extending direction of the sub-air outlets 3 is consistent with the extending direction of the air outlet 3.
In some embodiments, the length of the perpendicular from any point of the air outlet 3 to the edge of the channel 5 at the bottom of the housing is no more than 1cm. Specifically, the distance from any point of the air outlet 3 to the channel 5 is 1cm or less. According to bernoulli's principle: in the fluid medium (air flow), the pressure at the position with higher flow rate is lower than that at the position with lower flow rate, namely, the flow rate is high and the pressure is low; the flow rate is small and the pressure is large. The proximity of the outlet 3 to the channel 5 allows a faster flow rate of the air flow below the channel 5, so that the channel 5 and the air above the channel 5 can flow downwards.
In some embodiments, the length direction of the air outlet 3 is the second horizontal direction, and the air outlet 3 is adjacent to the first edge 51 in the first horizontal direction. Specifically, the air outlet 3 is a rectangular outlet, and the width direction of the air outlet 3 is a first horizontal direction. The air outlet 3 is adjacent to the first edge 51 in the first horizontal direction, i.e. the air outlet 3 is adjacent to the channel 5 in the first direction. The proximity of the outlet 3 to the channel 5 in the first direction allows a faster flow rate of the air flow below the channel 5, so that the channel 5 and the air above the channel 5 can flow downwards.
For example, the length direction of the air outlet 3 is the left-right direction, the width is the front-rear direction, and the air outlet 3 is adjacent to the first edge 51 (the passage 5) in the front-rear direction. The distance between the air outlet 3 and the channel 5 in the front-rear direction is 0.5cm. The air outlet 3 includes a plurality of sub-air outlets whose length direction is the left-right direction.
In some embodiments, the air outlet 3 is annular in horizontal cross section around the channel 5, the air outlet 3 being adjacent to the channel 5 in the horizontal direction. Therefore, the air flows discharged from the air outlet 3 are arranged on the periphery side of the bottom of the channel 5, so that the air flow speed below the channel 5 is high, the downward flow of the air above the channel 5 and the channel 5 is further facilitated, and the air flow for drying a user is large. For example, the annular air outlet 3 is in close contact with the inner housing 1.
In some embodiments, the bottom of the housing is provided with a sensing element 6, the sensing element 6 being adjacent to the air outlet 3 in a horizontal direction. Thereby, when the user stretches into the bottom of the bottom shell to enable the sensing element 6 to sense hands, the air flow of the fan is discharged from the air outlet 3 so as to dry. For example, the sensing element 6 may be a light sensor or a heat sensor.
The fan is arranged in the shell, and the outlet of the fan is communicated with the air outlet 3. The casing has the installation chamber and with the air intake 4 of installation chamber intercommunication, air intake 4 is located the bottom of casing. The installation cavity is provided with a ventilating duct and a fan, the inlet of the fan is communicated with the air inlet 4, the outlet of the fan is communicated with the inlet of the ventilating duct, and the outlet of the ventilating duct is communicated with the air outlet 3. Specifically, the air inlet 4 is provided on the bottom plate 25, so that dust is not easily accumulated at the air inlet 4. The air inlet 4 is formed by a plurality of sub-air inlets arranged in a matrix so as to increase the structural strength of the housing (the bottom plate 25), and the inlet of the fan is adjacent to the air inlet 4.
As shown in fig. 1 and 2, in some embodiments, the air outlet 3 extends in a horizontal direction, and the air outlet 3 and the air inlet 4 are located on both sides of the channel 5 in the horizontal direction. For example, the air outlet 3 and the air inlet 4 are located on both sides of the passage 5 in the front-rear direction.
As shown in fig. 3 and 4, in the first embodiment, the air outlet 3 extends in the second horizontal direction (left-right direction), and the air outlet 3, the sensing element 6, the duct 5, and the air inlet 4 are disposed in this order in the first horizontal direction (front-rear direction).
In the second embodiment, the air outlet 3 extends in the second horizontal direction (left-right direction), and the sensing element 6, the air outlet 3, the duct 5, and the air inlet 4 are disposed in this order in the first horizontal direction (front-rear direction).
