Temperature control controller with circuit board damage prevention structure

Abstract

The present invention relates to a temperature control controller having a circuit board damage prevention structure, wherein the circuit board is assembled to a front cover integrally formed with a lower operation button, thereby allowing for easy assembly, and when the upper operation button or the lower operation button is pressed, a push part spaced apart from the upper switch presses the upper switch, or a lower operation button spaced apart from the lower switch presses the lower switch, thereby preventing damage to the circuit board caused by malfunction of the upper or lower switches. According to the present invention, a push part and a lower operation button for pressing the upper and lower switches of a substrate are integrally formed on a base body, so that the substrate can be easily assembled to the base body. When assembling the substrate to the base body, the upper and lower switches are aligned with the positions of the push part and the lower operation button, thereby shortening the time required to assemble the substrate to the base body. Furthermore, since the upper and lower operation buttons are installed on the base body, there is no risk of the upper and lower operation buttons being pressed during the substrate assembly process. In particular, the upper and lower switches are prevented from being pressed by the upper and lower operation buttons during substrate assembly, thereby drastically reducing the rate of substrate damage. Additionally, the push part and the lower operation button are maintained at a predetermined distance from the upper and lower switches, so there is no risk of the upper and lower switches malfunctioning due to fine operation.

Description

Technology Field

[0001] The present invention relates to a temperature control controller, and more specifically, to a temperature control controller having a circuit board damage prevention structure that prevents malfunction of the upper and lower switches or damage to the circuit board by maintaining the push part and lower operation button of the base body at a predetermined distance from the upper and lower switches of the circuit board, while forming the lower operation button integrally so that it can be pressed on the base body, thereby preventing the upper and lower switches from being maintained in a pressed state due to the push part and lower operation button. Background Technology

[0002] Generally, a boiler consists of a temperature control controller (e.g., a room controller) installed on the wall of each room and a boiler installed on the wall of the boiler room, and the temperature control controller and the boiler maintain a communication connection.

[0003] Here, when the temperature controller installed in each room is operated, the communication signal from this temperature controller is transmitted to the integrated controller, and at this time, the integrated controller transmits the signal from each room's temperature controller to the boiler, thereby controlling and operating the boiler.

[0004] Patent Document 1 describes a conventional temperature control controller. Referring thereto, the controller comprises a substrate having an operation button formed on the front and a display formed on the upper side of the operation button, a finishing plate formed at the rear of the substrate that allows the substrate to be received and finishes the rear side of the substrate, a front portion formed at the front of the substrate that covers the front of the substrate by forming a step that divides the upper and lower parts of the front, and a through hole formed on the lower front portion based on the step to expose the operation button to the front, and a protector cover that covers the display, which is fastened to the step of the main body to cover the upper part based on the step of the main body.

[0005] Here, after receiving a circuit board with an integrally formed operation button into a finishing plate, and fastening the main body to the edge of the finishing plate so that the front of the circuit board is covered by the main body, the operation button is exposed to the front of the main body through a through hole, and the display of the circuit board is exposed to the front through a through hole formed through the front of the main body.

[0006] Then, the protector cover is positioned at a predetermined angle relative to the ledge of the main body, and with the bottom of the protector cover resting on the ledge of the main body, the top of the protector cover is rotated toward the front of the main body so that the protector cover covers the top of the main body.

[0007] However, the above-described patent document 1 has an operation button formed integrally on the front surface of the substrate, which can cause damage to the substrate or the operation button by forcibly pressing the operation button into the front surface during the process of assembling the substrate to the main body. Additionally, if the substrate is incorrectly assembled to the main body, the operation button remains pressed against the front surface, causing the temperature control controller to malfunction and resulting in damage to the substrate. Furthermore, since the operation button is in close contact with the front surface of the substrate, frequent malfunctions of the operation button occur due to fine operation. In particular, when assembling the substrate to the front surface, there is the inconvenience of having to precisely assemble the operation button so that it passes through the through hole of the front surface. Consequently, the assembly fixation is very inconvenient, and the assembly time is long, leading to a problem of reduced product reliability. Prior art literature

[0099] The upper entry guide surface (332b) is frictionally rubbed around the edge of the upper fastening hole (317) to guide the upper entry projection (332a) into the upper fastening hole (317).

[0101] A temperature control controller having a circuit board damage prevention structure according to the present invention configured as described above is used as follows.

[0102] First, a substrate (100) having a display (101) and upper and lower switches (102, 103) formed thereon is provided, and a front cover (300) and a rear cover (200) are positioned on the front and rear sides, respectively, based on the substrate (100), so that the edges of the front and rear covers (300, 200) are closely fastened to each other.

[0103] Then, the substrate (100) is covered by the front and rear covers (300, 200), and accordingly, the substrate (100) is wrapped between the front and rear covers (300, 200).

[0104] At this time, the display (101) of the substrate (100) passes through the through hole (312) formed in the base frame (310) of the front cover (300), and the display (101) is exposed to the front of the base body (310).

[0105] And, the push portion (313) of the base body (310) is positioned to correspond to the upper switch (102) of the substrate (100), and also, the lower operation button (314) is positioned to correspond to the lower switch (103).

[0106] At this time, the pressing part (313c) of the push part (313) is maintained at a fixed distance from the upper switch (102) while its center coincides with the center of the upper switch (102), and the lower operating button (314) is positioned to correspond to the lower switch (103) and is maintained at a fixed distance from the lower switch (103).

[0107] Next, the upper operating button (320) is positioned on the slit jaw (311) of the base body (310), and in that state, the fitting protrusion (321) of the upper operating button (320) is forcibly fitted into the fitting hole (311a) formed in the slit jaw (311) so that the upper operating button (320) is maintained in a state of being fastened to the slit jaw (311).

[0108] Here, when the fixing projection (321a) of the insertion projection (321) is inserted into the insertion hole (311a), the entry guide surface (321b) is frictionally applied around the edge of the insertion hole (311a), thereby guiding the fixing projection (321a) to enter the center of the insertion hole (311a), so that the fixing projection (321a) is inserted and fixed within the insertion hole (311a).

[0109] Then, the upper operating button (320) is fixed to the slit jaw (311), and at this time, the fastening protrusion (325) of the upper operating button (320) is fitted and fixed into the fastening hole (318) of the base body (310), so that both ends of the upper operating button (320) are fixed in close contact with the front of the base body (310).

[0110] In particular, as the upper operating button (320) is fixed to the slit jaw (311), each of the buttons (322) is positioned to correspond to the push portion (313), and accordingly, the operating projection (324) is maintained in a state of close contact with the pressing portion (313c) of the push portion (313).

[0111] Next, the protector cover (330) is positioned in front of the base body (310), and with the top of the protector cover (330) tilted away from the base body (310), the bottom of the protector cover (330) is pressed against the seating ledge (315).

[0112] Then, when the upper end of the protector cover (330) is rotated toward the base body (310) with respect to the above-mentioned mounting portion (315), the side connecting projection (331) of the protector cover (330) is inserted and coupled into the side connecting hole (316) of the base body (310), and the upper connecting projection (332) is inserted and coupled into the upper connecting hole (317) of the base body (310), so that both ends and the upper end of the protector cover (330) are closely coupled to both sides and the upper surface of the base body (310).

[0113] That is, as the protector cover (330) is rotated and fastened, the side entry projection (331a) of the side joint connecting projection (331) enters the side joint connecting hole (316) to a predetermined depth, and by positioning the side locking projection (331b) within the side joint connecting hole (316), the side locking projection (331b) is locked and fixed within the side joint connecting hole (316).

[0114] Additionally, the upper entry guide surface (332b) of the upper fastening projection (332) frictionally contacts the edge of the upper fastening hole (317), thereby guiding the upper entry projection (332a) to be inserted and fastened into the center of the upper fastening hole (317), so that the upper entry projection (332a) is inserted and fixed within the upper fastening hole (317).

[0115] Then, the protector cover (330) is fixed in close contact with the front of the base body (310), and at this time, the display (101) is visible through the protector cover (330) made of a transparent material.

[0116] Afterwards, the rear cover (200) is fixedly installed on the wall of the indoor space, and when the upper operation button (320) is pressed in that state, the button (322) of the upper operation button (320) is pressed, and the pressing part (313c) of the push part (313) is pressed by the operating projection (324). At this time, the pressing part (313c) moves toward the upper switch (102), thereby pressing and operating the upper switch (102).

[0117] Here, by pressing the upper switch (102), an operation signal corresponding to the input of the upper switch (102) is output to the display (101), and at the same time, an operation signal is output to an integrated controller (not shown) or a boiler (not shown).

[0118] At this time, the elastic extension part (313b) connected to the pressure part (313c) is bent by the pressure part (313c) and guides the pressure part (313c) to move toward the upper switch (102). Then, at the moment the pressing of the button (322) is released, it is restored to its original state by the elastic force, thereby returning the pressure part (313c) to its original position.

[0119] In particular, the above buttons (322) are maintained in a state of being connected to each other by the connecting part (323), and by the operation of pressing the above buttons (322), the connecting part (323) bends in the press-fit direction with respect to the above removal groove (323a), thereby independently operating each of the above buttons (322).

[0120] Then, the above-mentioned pressurizing part (313c) is maintained at a predetermined distance from the above-mentioned upper switch (102).

[0121] On the other hand, when the lower operation button (314) is pressed, the lower switch (103) is pressed by the lower operation button (314), and at this time, an operation signal corresponding to the input of the lower switch (103) as described above is output to the display (101), and at the same time, an operation signal is output to an integrated controller (not shown) or a boiler (not shown).

[0122] At this time, the lower operating button (314) is formed integrally on the front surface of the base body (310) in an injection molding method to have elasticity, so that it returns to its original position after pressing.

[0123] Here, the lower operating button (314) is maintained at a predetermined distance from the lower switch (103).

[0124] That is, the pressing part (313c) of the push part (313) and the lower operating button (314) are maintained at a predetermined distance from the upper and lower switches (102, 103), thereby preventing the upper and lower switches (102, 103) from malfunctioning due to fine operation of the upper operating button (320) or the lower operating button (314).

[0125] As described above, the structure for preventing the upper and lower operation buttons (320, 314) from malfunctioning due to the push part (313) and lower operation button (314) by forming the push part (313) and lower operation button (314) of the base body (310) at a predetermined distance from the upper and lower switches (102, 103) is such that the push part (313) and lower operation button (314) that press and operate the upper and lower switches (102, 103) of the substrate (100) are integrally formed on the base body (310), allowing the substrate (100) to be easily assembled to the base body (310), and when the substrate (100) is assembled to the base body (310), the upper and lower switches (102, 103) align with the positions of the push part (313) and lower operation button (314), thereby allowing the substrate (100) The time required to assemble the base body (310) can be shortened.

[0126] The temperature control controller having a circuit board damage prevention structure according to the present invention described above is not limited to the embodiments described above, and its technical spirit extends to the scope in which any person with ordinary knowledge in the field to which the present invention belongs can implement it by making various modifications without departing from the gist of the present invention as claimed in the following claims.
