Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a heating evaporator suitable for deodorizing a room or aroma.
[0002]
[Prior art]
For example, Japanese Patent Laid-Open No. 8-148 discloses a heating evaporator that vaporizes and evaporates a liquid such as a chemical solution to deodorize a room.
[0003]
The outline of the heating evaporator is that a heating element such as a heater is provided in the evaporator body with the liquid container set at the lower part, and heat is applied to the liquid absorption core that sucks up the chemical in the liquid container by the heating element. It has a structure that promotes vaporization and transpiration and diffuses to the outside from the transpiration port provided above the evaporator body.
[0004]
[Problems to be solved by the invention]
The chemical liquid in the liquid container is heated by a heating element such as a heater so that vaporization and transpiration are promoted and diffused out of the transpiration port, but the transpiration port has a constant opening area. It is a fixed type.
[0005]
The opening area of the evaporation port is designed based on the size of the standard room to be used, so when using it in a room larger than the standard, there is a surface that the vaporized chemical solution is difficult to spread throughout the room, On the other hand, when used in a small room, there is a problem that it is not possible to respond in detail according to the size of the room to be used, such as being excessively spread over the whole room.
[0006]
Accordingly, an object of the present invention is to provide a heating evaporator that can be used in an optimum state according to the size of the room.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, according to claim 1 of the present invention, a liquid container provided with a liquid absorption core for sucking up an internal chemical solution, and a evaporator having a liquid container set at the lower part and a transpiration port at the upper part. It consists of a main body and a heating unit that is fixedly supported in the main body of the evaporator and heats the liquid absorption core, and the evaporation port is vaporized by controlling the opening area of the evaporation port small by an opening control means. When the chemical solution passes through the transpiration port, the flow rate becomes high and rises upward, and by controlling the opening area of the transpiration port widely, the vaporized chemical solution flows through the transpiration port. It is possible to adjust so as to slow down and rise low .
[0008]
Thereby, for example, when the room to be used is large, the opening area of the evaporation port is controlled to be small. As a result, when the vaporized chemical solution passes through the transpiration port, the flow velocity increases due to the reduction in the cross-sectional area of the flow path, rises upward, and spreads over a wide area. It becomes like this. Moreover, when the room to be used is small, the opening area of the transpiration port is controlled widely. As a result, when the vaporized chemical solution passes through the transpiration port, the flow velocity slows down due to the enlargement of the cross-sectional area of the flow path, and it rises low. From small to small rooms can be used in an optimal state.
[0009]
According to the second aspect of the present invention, the opening degree control means is integrally fixed to the operation lever protruding outward from the evaporator body and the operation lever, and the opening area of the evaporation port is enlarged or reduced by sliding movement. It is characterized by comprising a control door.
[0010]
Thus, by operating the operation lever according to the size of the room, it becomes possible to easily control the opening area of the transpiration port, and the structure can be simplified.
[0011]
According to a third aspect of the present invention, the opening degree control means is a drive that fully opens the transpiration port when the plug of the evaporator body is attached to the socket and fully closes the transpiration port when the plug is removed from the socket. It is characterized by comprising a control door of the type.
[0012]
Thereby, when not in use, the transpiration port is fully closed, so that it is possible to delay wasteful natural vaporization of the chemical liquid.
[0013]
According to a fourth aspect of the present invention, the transpiration port is formed by a main opening and a sub-opening opening provided near the main opening and having a smaller opening area than the main opening.
[0014]
As a result, a wide diffusion state can be obtained, and the liquid can surely come out from the evaporation port, so that there is no adhesion of the chemical solution vaporized inside.
[0015]
According to claim 5 of the present invention, the evaporator body is provided with an air inlet having a total opening area larger than the total opening area of the transpiration port.
[0016]
Thereby, the upward flow toward a transpiration port increases, and it becomes possible to diffuse the chemical | medical solution vaporized within the transpiration | evaporator main body smoothly outside.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to FIGS. 1 to 6.
[0018]
FIG. 1 shows a schematic cross-sectional view of the heating evaporator 1.
[0019]
The evaporator body 3 of the heating evaporator 1 is made of a synthetic resin material, and a heating unit 5 is arranged inside, while a liquid container 7 containing a chemical solution is detachably inserted and set in the lower part. ing. The evaporator body 3 can be divided into the front and rear 3a, 3b from the butt line 11 shown in FIG. 3 by loosening the fastening screw 9, and the evaporation port 13 is provided at the center of the upper surface of the evaporator body 3, and the lower part thereof. A slit-like air intake 15 is provided on each of the left and right sides when viewed from the front.
[0020]
The air inlet 15 has a total opening area larger than the total opening area of the transpiration port 13, and a reliable upward flow from the air intake 15 toward the upper transpiration port 13 is ensured.
[0021]
The transpiration port 13 is formed by a main opening 17 that is formed in a round hole shape and penetrates vertically, and a sub-opening opening 19 having a smaller opening area than the main opening 17 at the four peripheral edges of the main opening 17. The opening area can be adjusted by the degree control means 21.
[0022]
The opening degree control means 21 is a band-plate-shaped member that expands / contracts the opening area of the transpiration port 13 by a manual operation lever 23 protruding outward from the evaporator body 3 and sliding movement of the operation lever 23 (arrow in FIG. 1). The control door 25 is comprised.
[0023]
As shown in FIG. 3, the operating lever 23 can be slid upward and downward with the standard position P1 as the center. By operating the operating lever 23 downward, the opening area of the transpiration port 13 increases sequentially, and the opening is opened at the lowest position. It is set to maximize the area.
[0024]
By operating upward from the standard position P1, the opening area of the transpiration port 13 is sequentially reduced, and the opening area is set to be the smallest at the highest position.
[0025]
In this case, the control door 25 is an embodiment of a size that controls the main opening 17 and the sub opening 19 simultaneously. For example, as shown by a two-dot chain line in FIG. In addition to the main control door S1 that controls opening and closing, a U-shaped sub control door S2 that controls opening and closing of the sub opening 19 across the control door S1 is provided, and each of the control doors S1 and S2 can be operated independently. You may do it. As a result, the opening area can be adjusted over a wide range.
[0026]
As shown in FIG. 5, a drive type control door 29 that is controlled by a solenoid 27 is provided in the transpiration port 13, and the transpiration port 13 is fully closed when the plug 31 of the evaporator body 3 is attached to the socket 33. At the same time, the transpiration port 13 may be fully closed when the plug 31 is removed from the socket 33. As a result, when not in use, the transpiration port 13 is fully closed, so that it is possible to delay wasteful natural vaporization.
[0027]
On the other hand, the liquid container 7 has a liquid absorption core 35 extended upward from the container main body 7a through the cap mounting portion 7b, and is formed in an elliptical shape on the front surface of the container main body 7a as shown in FIG. An engaging projection 37 is provided.
[0028]
When the container main body 7 a is inserted into the lower part of the evaporator main body 3, the engaging protrusion 37 forcibly expands the skirt of the evaporator main body 3, and the engaging hole 39 provided in the evaporator main body 3. The fixing support of the liquid container 7 is ensured by the engagement state between the engagement hole 39 and the engagement protrusion 37 by the restoring force that the skirt of the evaporator body 3 returns to the original by engaging with each other. It has become.
[0029]
The liquid absorption core 35 is made of a material resistant to heat that absorbs the chemical solution of the container body 7. When the liquid container 7 is inserted and set in the lower part of the evaporator body 3, the liquid absorption core 35 is slightly above the heating element 45 of the heating unit 5. The length that protrudes to
[0030]
As shown in FIG. 6, the heating unit 5 is surrounded by an insulating material, and includes a heating control unit 43 and a heating element 45, and the mounting unit 47 is a support member provided in the evaporator body 3 by screws 49. 51 is fixedly supported. The terminal 43 a of the heating control unit 43 is mounted on the support member 51 and is electrically connected to the plug 31 protruding from the rear side of the evaporator body 3. By inserting the plug 31 into the socket 33, current is supplied. It is a PTC heater that flows and heats the heating element 45.
[0031]
The heating element 45 is formed in a ring shape that surrounds the outer periphery of the liquid absorbent core 35 with a slight gap.
[0032]
In FIG. 2, reference numeral 53 denotes a pilot lamp which is turned on during use.
[0033]
According to the heating and evaporating apparatus 1 configured as described above, heat is applied to the liquid absorption core 35 by inserting the plug 31 into the socket 33, and the vaporized chemical liquid is diffused out from the evaporating port 13. At this time, a reliable upward flow toward the transpiration port 13 is obtained by the air intake port 15, and the main opening port 17 and the sub-opening port 19 surely let it go out, so that there is no adhesion of the chemical solution vaporized inside. .
[0034]
On the other hand, for example, when used in a large room from a standard room (about 6 cm), the operating lever 23 is operated to reduce the opening area of the transpiration port 13. Thereby, since the flow-path cross-sectional area of the transpiration port 13 becomes narrow, the flow velocity at the time of passing through the transpiration port is increased, so that it rises high upward and reliably spreads over a wide range.
[0035]
Next, when the room to be used is small, the operating lever 23 is operated to increase the opening area of the transpiration port 13. Thereby, since the flow-path cross-sectional area of the transpiration port 13 spreads, and the flow velocity at the time of passing through the transpiration port becomes slow, it rises low and diffuses over a narrow range.
[0036]
Therefore, it can be used in an optimal state according to a small room to a large room.
[0037]
【The invention's effect】
As described above, according to the first aspect of the present invention, it can be used in an optimal state from a small room to a large room by adjusting the opening area of the transpiration port by the opening control means.
[0038]
According to the second aspect of the present invention, since the opening and closing control of the transpiration port is performed by the operation lever and the control door, the structure can be simplified.
[0039]
According to the third aspect of the present invention, since the evaporation port can be fully closed when not in use, wasteful natural vaporization of the chemical solution can be delayed.
[0040]
According to the fourth aspect of the present invention, the chemical liquid vaporized over a wide area can be diffused by the main opening and the sub-opening opening, and the chemical liquid vaporized inward can be surely removed from the evaporation port. Particle adhesion is eliminated.
[0041]
According to the fifth aspect of the present invention, the upward flow toward the transpiration port is increased by the air intake having a large opening area, and the vaporized chemical liquid can be smoothly diffused to the outside.
