Description

Technical Field

[0001] The present application relates to the technical field of heating equipment, and in particular to an air inlet grille and a heater. Background Art

[0002] Temperature sensors are essential and important components in heating equipment such as heaters. They are used to detect the ambient temperature in order to achieve adaptive adjustment of the heating power of the heater. For heaters, the outer shell and internal structure of the heater are easily affected by the heating element itself and increase the temperature. In traditional designs, temperature sensors are usually directly installed on the outer shell of the heater. Therefore, the temperature detection data of the temperature sensor is easily affected and causes misjudgment of the heater. Therefore, in some improvement schemes, in order to reduce the influence of the heating element in the outer shell on the temperature sensor, technicians choose to install the temperature sensor at a position far away from the heating element, such as installing the temperature sensor at the bottom of the outer shell. However, this will cause the temperature sensor's temperature measuring probe to be unable to fully contact the ambient airflow for temperature measurement, which will also cause inaccurate temperature measurement results.

[0026] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0027] In the description of the present application, it should be understood that the terms "length", "width", "thickness", "up", "down", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or state relationships based on the positions or state relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0028] In addition, some of the above terms may be used to express other meanings in addition to indicating a position or state relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0029] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0030] In addition, unless otherwise expressly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be internal communication between two elements, or it can be only surface contact. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] If certain words are used in the specification and claims to refer to specific components, those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use differences in names as a way to distinguish components, but use differences in components' functions as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to"; "substantially" means that those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0032] See also Figure 1 and Figure 2 , the embodiment of the present application provides an air inlet grille 100, which is applied to a heater 200 (see Figure 7 ), which is a structure that the outside air needs to pass through when entering the interior of the heater 200. The air inlet grille 100 includes a grille plate 10 and a temperature sensor 40. The grille plate 10 is the main structure of the air inlet grille 100, which is a plate-like structure. As a specific example, in the drawings of this specification, the grille plate 10 is a roughly rectangular plate-like structure. In other embodiments, the grille plate 10 can also be a plate-like structure that is roughly square, circular, or other shapes.

[0033] The grille plate 10 is provided with a detection hole 101 and a plurality of air inlet holes 102. The grille plate 10 has a first side 20 and a second side 30 that are arranged opposite to each other. The first side 20 is the air inlet side. The detection hole 101 and the air inlet hole 102 both penetrate the first side 20 and the second side 30. When the heater 200 is working, the external airflow can move from the first side 20 through the air inlet holes 102 and the detection hole 101 to the second side 30, so the first side 20 is the "air inlet side". The "first side 20" can be understood as the side of the grille plate 10 away from the interior of the heater 200, and the "second side 30" can be understood as the side of the grille plate 10 close to the interior of the heater 200.

[0034] The temperature sensor 40 is fixedly arranged on the grille plate 10 and located on the second side 30. The temperature sensor 40 includes a temperature measuring probe 401. The temperature measuring probe 401 is arranged corresponding to the detection hole 101 so that the temperature measuring probe 401 is exposed on the first side 20 through the detection hole 101. The above-mentioned "exposed on the first side 20" should be understood as: the user can observe the temperature measuring probe 401 through the detection hole 101 on the first side 20, and the outside air can pass through the temperature measuring probe 401 when passing through the detection hole 101, so that the temperature measuring probe 401 can obtain detection data.

[0035] Through the above arrangement, when the air inlet grille 100 is installed on the heater 200 for use, the external airflow can enter the interior of the shell of the heater 200 from the detection hole 101 and the air inlet hole 102. When the airflow passes through the detection hole 101, it will pass through the temperature probe 401 of the temperature sensor 40, so that the temperature sensor 40 can detect the ambient temperature. And because the temperature probe 401 of the temperature sensor 40 is far away from the shell and internal structure of the heater 200, it can reduce the detection error caused by the heating element of the heater 200 to the temperature sensor 40, thereby improving the detection accuracy of the temperature sensor 40, and further ensuring that the heater 200 can accurately control the temperature. In addition, because the temperature probe 401 can be suspended through the detection hole 101, the temperature probe 401 does not need to contact the grille plate 10, so the error effect of the grille plate 10 on the temperature sensor 40 can be reduced, thereby further improving the temperature measurement accuracy of the temperature sensor 40.

[0036] See also Figure 4 In some embodiments, the temperature sensor 40 further includes a connecting wire 402, which is an electric wire or a conducting wire with a rubber sleeve or a plastic sleeve on the outer surface, and one end of the connecting wire 402 is electrically connected to the temperature measuring probe 401. The air inlet grille 100 further includes a fixing component 50, which is disposed on the grille plate 10 and located on the second side 30, and the fixing component 50 fixes the connecting wire 402 on the grille plate 10.

[0037] Through the above arrangement, the fixing assembly 50 can improve the stability of the connection between the temperature sensor 40 and the grid plate 10, thereby ensuring that the position of the temperature sensor 40 remains stable, so that the temperature sensor 40 can perform stable temperature measurement.

[0038] Please continue reading Figure 4 In some embodiments, the fixing assembly 50 includes a receiving groove 501 and a clamping member 502. The receiving groove 501 is located on the second side 30. The connecting wire 402 is located in the receiving groove 501 and is routed along the extension direction of the receiving groove 501. The clamping member 502 clamps and fixes the connecting wire 402 in the receiving groove 501 to achieve a stable connection between the connecting wire 402 and the receiving groove 501.

[0039] Through the above arrangement, the accommodating groove 501 can guide the routing of the connecting wire 402 and can also protect the connecting wire 402 to reduce the possibility of the connecting wire 402 being accidentally pulled and moved, thereby further improving the stability of the temperature sensor 40 installed on the grid plate 10.

[0040] Please also see Figure 5 and Figure 6 In some embodiments, the accommodating groove 501 includes a straight section 5011 and a curved section 5012, the curved section 5012 is continuously connected to the straight section 5011, the curved section 5012 is located at one end of the straight section 5011 close to the detection hole 101, and is bent relative to the straight section 5011, and the connecting line 402 is laid along the curved section 5012 and the straight section 5011. Among them, the straight section 5011 extends roughly along a straight line, and the curved section 5012 extends along a curve. As a specific example, in the drawings of the specification of this embodiment, the curved section 5012 is roughly in the shape of a semicircular ring. In other embodiments, the curved section 5012 can also be in the shape of a wavy curve or any other arbitrary curve shape, which is not limited to this.

[0041] Through the above-mentioned arrangement, since the accommodating groove 501 is provided with a straight section 5011 and a curved section 5012, the connecting line 402 is laid along the straight section 5011 and the curved section 5012, so the connecting line 402 itself will also bend when passing through the curved section 5012. At this time, when the connecting line 402 is pulled by an external force, the curved section 5012 can form an obstacle to the connecting line 402, thereby reducing the possibility of the connecting line 402 moving after being pulled. Therefore, the stability of the connection between the temperature sensor 40 and the grille plate 10 can be further improved, and the occurrence of inaccurate detection results due to accidental movement of the temperature measuring probe 401 of the temperature sensor 40 can be avoided as much as possible.

[0042] See also Figure 4In some embodiments, the fixing assembly 50 further includes a guide post 503 and a positioning member 504. The guide post 503 is disposed in the curved section 5012 and is specifically connected to the grille plate 10. The connecting wire 402 surrounds the outer periphery of the guide post 503 to form a curved structure. The positioning member 504 is connected to the guide post 503. The positioning member 504 presses the connecting wire 402 against the curved section 5012. As a specific example, in the drawings of the specification of this embodiment, the guide post 503 is a substantially cylindrical structure, the central axis of which is substantially perpendicular to the grille plate 10. The guide post 503 is provided with a threaded hole along the direction of its central axis. The positioning member 504 is a bolt, the rod of which is threadedly inserted into the threaded hole to achieve the connection between the positioning member 504 and the guide post 503. The head of the bolt presses the connecting wire 402 against the curved section 5012 to fix the connecting wire 402. In other embodiments, the positioning member 504 may also be a fastener such as a screw or a rivet. After the positioning member 504 is connected to the guide column 503 , the head of the positioning member 504 can press the connecting wire 402 to fix the connecting wire 402 .

[0043] Through the above-mentioned arrangement, the guide column 503 realizes the connection between the positioning member 504 and the grille plate 10, and the positioning member 504 can improve the stability of the connection between the connecting wire 402 and the grille plate 10 by pressing the connecting wire 402 against the bending section 5012, thereby further improving the stability of the connection between the temperature sensor 40 and the grille plate 10 to ensure that the temperature measuring probe 401 can measure the temperature accurately and stably.

[0044] Please continue reading Figure 6 In some embodiments, the fixing assembly 50 further includes a clamping rib 505, which is disposed on the inner side wall of the receiving groove 501 and is spaced relative to the guide column 503, and the connecting wire 402 is clamped between the clamping rib 505 and the guide column 503. As a specific example, in the drawings of the specification of this embodiment, the clamping rib 505 is a plate-like structure disposed on the inner side wall of the receiving groove 501, and the connecting wire 402 passes through the gap between the clamping rib 505 and the guide column 503 and is clamped and fixed by the clamping rib 505 and the guide column 503. Through the above arrangement, the stability of the connecting wire 402 in the receiving groove 501 can be improved, that is, the stability of the installation of the temperature sensor 40 can be improved. In other embodiments, a serrated structure may be further provided on the surface of the clamping rib 505 facing the guide column 503 , which can improve the clamping effect of the clamping rib 505 and the guide column 503 on the connecting wire 402 , and further improve the stability of the connecting wire 402 in the receiving groove 501 .

[0045] In some embodiments, the air inlet grille 100 further includes a buffer 60, which is disposed on the positioning member 504 and is squeezed between the positioning member 504 and the connecting line 402. As a specific example, the buffer 60 may be an annular structure made of rubber or silicone material, which is disposed on the surface of the positioning member 504 facing the guide column 503. When the positioning member 504 is connected to the guide column 503, the buffer 60 will be pressed against the connecting line 402 by the positioning member 504, thereby avoiding direct contact and friction between the positioning member 504 and the connecting line 402, so as to protect the connecting line 402. Through the above arrangement, the soft buffer 60 can better fit the connecting line 402, so as to increase the pressing area of ​​the positioning member 504 on the connecting line 402, and while protecting the connecting line 402, it can also improve the pressing and fixing effect of the positioning member 504 on the connecting line 402.

[0046] In some embodiments, the receiving groove 501 may be a groove-shaped structure formed by a recessed structure disposed on the second side 30 of the grid plate 10, or may be a groove-shaped structure formed by a recess of the grid plate 10 itself, or may be a groove-shaped structure defined by a surrounding plate disposed on the grid plate 10 (in this embodiment, the receiving groove 501 is formed by a surrounding plate, and the surrounding plate includes the "bottom plate 5013" and the "side plate 5014" hereinafter). In this embodiment, the receiving groove 501 includes a bottom plate 5013 and two side plates 5014 disposed relatively spaced apart, and the bottom plate 5013 is located between the two side plates 5014, so as to be spliced ​​together to define the receiving groove 501. The clamping member 502 includes a first clamping portion 5021 and a second clamping portion 5022, the first clamping portion 5021 and the second clamping portion 5022 are respectively connected to the two side plates 5014, the first clamping portion 5021 and the second clamping portion 5022 are arranged at intervals, and the connecting line 402 passes through the gap between the first clamping portion 5021 and the second clamping portion 5022 and is clamped and fixed by the first clamping portion 5021 and the second clamping portion 5022. As a specific example, in the drawings of the specification of this embodiment, the clamping member 502 is arranged in the straight section 5011 of the receiving groove 501, and the number is one. In other embodiments, the clamping member 502 can be arranged not only in the straight section 5011, but also in the curved section 5012, and the number of the clamping members 502 can also be two, three, four, etc., which is not limited to this, and the plurality of clamping members 502 are arranged in sequence along the extending direction of the receiving groove 501.

[0047] Through the above arrangement, since the connecting wire 402 passes through the gap between the first clamping portion 5021 and the second clamping portion 5022 and is clamped, the stability of the connecting wire 402 in the receiving groove 501 can be improved, thereby improving the stability of the connection between the temperature sensor 40 and the grille plate 10. In addition, the clamping member 502 can also prevent the connecting wire 402 from loosening and shifting due to vibration during the operation of the heater 200, thereby causing the temperature sensor 40 to measure the temperature inaccurately.

[0048] Please continue reading Figure 6 In some embodiments, the fixing assembly 50 further includes an elastic hook 506, which includes a first clamping portion 5061 and a second clamping portion 5062. The first clamping portion 5061 and the second clamping portion 5062 are respectively connected to the two side panels 5014, and the first clamping portion 5061 and the second clamping portion 5062 are spaced apart. The temperature measuring probe 401 passes through the gap between the first clamping portion 5061 and the second clamping portion 5062 and is clamped and fixed by the first clamping portion 5061 and the second clamping portion 5062. The "elasticity" in the "elastic hook 506" should be understood as: at least part of the structure of the elastic hook 506 (used to contact the temperature probe 401) is made of elastic material (such as elastic plastic, rubber or silicone, etc.). Since this part of the structure is elastic, it can not only increase the fitting area between the elastic hook 506 and the temperature probe 401 and improve the fixing effect, but also avoid hard contact between the elastic hook 506 and the temperature probe 401, thereby protecting the temperature probe 401 from damage. As a specific example, in the drawings of the specification of this embodiment, the first clamping portion 5061 and the second clamping portion 5062 are respectively arranged at one end of the two side plates 5014 close to the detection hole 101, and at least part of the temperature probe 401 passes through the gap between the first clamping portion 5061 and the second clamping portion 5062 and is clamped. Through the above arrangement, the elastic hook 506 can reinforce the temperature measuring probe 401 of the temperature sensor 40, thereby ensuring that the temperature measuring probe 401 is always located at the detection hole 101, so that the temperature measuring probe 401 can accurately measure the temperature of the airflow passing through the detection hole 101. In addition, the first clamping portion 5061 and the second clamping portion 5062 are both provided with hook structures at one end away from the side plate 5014, and the two hook structures are arranged opposite to each other to clamp the temperature measuring probe 401 together, which can further improve the clamping effect of the elastic hook 506 on the temperature measuring probe 401.

[0049] Please refer again Figure 1In some embodiments, a plurality of air inlet holes 102 are arranged on the grille plate 10 according to a certain period. The above-mentioned "certain period" should be understood as: the plurality of air inlet holes 102 can be arranged according to any arrangement rules such as matrix arrangement, horizontal / vertical arrangement, star-shaped arrangement or concentric circle arrangement. Among them, the air inlet holes 102 can have a variety of specifications and styles with different shapes. For example, the plurality of air inlet holes 102 can include at least one of holes of different shapes such as a perfect circle hole, an elliptical hole, a rectangular hole, or a plurality of air inlet holes 102 include holes of the same shape but different sizes. In the drawings of the specification of the present embodiment, the air inlet holes 102 are all long waist-shaped holes, but the lengths of different air inlet holes 102 are different. The plurality of air inlet holes 102 are roughly arranged and distributed in a matrix, so as to enrich the style of the air inlet holes 102 and improve the aesthetics of the air inlet grille 100. In other embodiments, the air inlet holes 102 can also be through holes of other styles such as a circular hole, a rectangular hole, etc., which are not limited to this. For further information, please refer to Figure 2 and Figure 3 A blind hole 103 is provided on the first side 20 of the grille plate 10. The contour of the blind hole 103 is the same as the contour of at least one of the plurality of air inlet holes 102. The arrangement of the blind hole 103 and the plurality of air inlet holes 102 follows a certain period (that is, the blind hole 103 and the plurality of air inlet holes 102 are arranged and combined according to a certain specification pattern). The accommodating groove 501 is located on the second side 30 of the grille plate 10 at a position corresponding to the blind hole 103.

[0050] Through the above arrangement, since the contour of the blind hole 103 is the same as the contour of at least one of the plurality of air inlet holes 102, the consistency of the arrangement and distribution of the plurality of air inlet holes 102 can be ensured, thereby ensuring the aesthetics of the air inlet grille 100. Moreover, since the receiving slot 501 is located at the position corresponding to the blind hole 103 on the second side 30 of the grille plate 10, the blind hole 103 can shield the connection line 402 between the receiving slot 501 and the temperature sensor 40 to prevent the user from seeing the exposed connection line 402 on the first side 20, thereby further improving the aesthetics of the air inlet grille 100. In addition, the arrangement of the blind hole 103 can also prevent the airflow from blowing directly to the temperature sensor 40, thereby preventing the temperature sensor 40 from being accidentally displaced, thereby further improving the stability of the connection between the temperature sensor 40 and the grille plate 10.

[0051] Please continue reading Figure 1 The plurality of air inlet holes 102 together constitute an air inlet area 104 (i.e. Figure 1), the air inlet area 104 has a height direction X and a width direction Y that are perpendicular to each other, the minimum distance from the detection hole 101 along the height direction X to the edge of the air inlet area 104 is greater than one-third of the maximum dimension of the air inlet area 104 in the height direction X, and the minimum distance from the detection hole 101 along the width direction Y to the edge of the air inlet area 104 is greater than one-third of the maximum dimension of the air inlet area 104 in the width direction Y. The above-mentioned "the minimum distance from the detection hole 101 to the edge of the air inlet area 104 along the height direction X" should be understood as: the minimum straight-line distance from the central axis of the detection hole 101 to any edge line of the air inlet area 104 along the height direction X. Similarly, the above-mentioned "the minimum distance from the detection hole 101 to the edge of the air inlet area 104 along the width direction Y" should be understood as: the minimum straight-line distance from the central axis of the detection hole 101 to any edge line of the air inlet area 104 along the width direction Y".

[0052] Through the above configuration, it is possible to ensure that the detection hole 101 is approximately located in the center of the air inlet area 104, avoiding the detection hole 101 being too close to the edge of the air inlet area 104, thereby reducing the error caused by the high temperature area around the air inlet area 104 on the temperature measurement of the temperature sensor 40.

[0053] See also Figure 7 Based on the above-mentioned air inlet grille 100, this embodiment also provides a heater 200, and the heater 200 includes a shell 201, a heating device (not shown in the figure) and the above-mentioned air inlet grille 100. As a specific example, in the drawings of the specification of this embodiment, the shell 201 is roughly in the shape of a rectangular parallelepiped. In other embodiments, the shell 201 can also be roughly in the shape of a cube, a cylinder or any other shape, which is not limited to this. The heating device is arranged in the shell 201, and is used to generate high temperature to heat the air to achieve a heating effect. The air inlet grille 100 is connected to the shell 201, and the detection hole 101 and the air inlet hole 102 connect the internal space of the shell 201 with the outside world, so that the outside air enters the interior of the heater 200 through the air inlet grille 100.

[0054] Through the above-mentioned arrangement, the outside air can be detected by the temperature measuring probe 401 of the temperature sensor 40 when passing through the detection hole 101, thereby facilitating the temperature sensor 40 to obtain the real and accurate ambient temperature. Moreover, since the temperature sensor 40 is arranged at a roughly middle position of the air inlet grille 100, the error in the detection result caused by other high-temperature areas such as the shell 201 can be reduced, so that the heater 200 can achieve precise temperature control and improve the user experience.
