Description

The present invention relates to an outlet mechanism of a carbon dioxide gas generator.

Regarding the outlet mechanism of the carbon dioxide gas generator, the applicant has made a useful proposal. That is, Japanese Patent Application Laid-Open No. 2014-12190 (referred to as Document (1)). The present invention intends to optimize the concentration and temperature by mixing with the inside air or exhausting CO2 while suppressing the abnormal generation of CO2 (carbon dioxide gas) due to incomplete combustion. However, it is considered that further improvement is desired in terms of physically adjusting the optimization of the outlet temperature while using the outlet.

It is rational and effective to provide a pair of outlets as a method for optimizing the outlet temperature while using this outlet.

Based on this idea, if there is a prior document, there is a device described in Japanese Patent Publication No. 48-36048 (referred to as Reference (2)). This device has a structure having two exhaust ports (branch ducts) in the duct, but it uses the carbon dioxide gas of the carbon dioxide gas cylinder, does not handle the temperature of the carbon dioxide gas, and simply uses the branch duct. , It is considered that the carbon dioxide gas is dispersed. In addition, there is a device described in Japanese Patent Publication No. 53-54839 (referred to as Reference (3)). This idea is a combination of a heater and a carbon dioxide generator. Utilizing the common use of kerosene, a valve is provided in the duct of the heater, and the control of this valve controls the carbon dioxide generated during the use of the heater. , It is a structure to discharge into the house. Therefore, it is considered that the operation of the heater is indispensable, the usage period is limited, and the versatility is lacking.

Hereinafter, a preferred embodiment of the present invention will be described.

The carbon dioxide gas generator A shown in FIG. 1 and the like is arranged so as to be adjacent to the wife surface H1 of the house H. Explaining the carbon dioxide gas generator A, the carbon dioxide gas generator A is composed of a rectangular main body 1 and a hot air chamber 2 communicating with the main body 1, and the upper opening 1a of the main body 1 is warm. It communicates with the lower opening 2a of the air chamber 2. Therefore, as will be described later, the combustion gas B generated in the can body 100 is sent to the warm air chamber 2 (combustion gas chamber).

At the center of the main body 1 (an example), a space area A1 (a region between the inner peripheral surface of the main body 1 and the can body 100) is provided on the inner peripheral surface thereof, and the can body 100 which is a combustion chamber is provided. Has been done. An injection port of the burner 101 is provided on the side surface of the can body 100 (to the left in FIG. 1). Further, on the upper part of the can body 100, a combustion gas discharge pipe 102 (with a diffusion umbrella) facing upward (upward in FIG. 1) is provided. A blower 103 is provided at the lower part of the can body 100 (downward in FIG. 2). In the figure, 104 is a pump for sending fuel, and 105 is a plurality of air intake holes 105 provided in the lower wall plate of the can body 100, and air inside (outside) the house is taken into the can body 100. In the figure, 106 shows a control device. The control device 106 controls the burner 101, the blower 103, the pump 104, and the like.

Further, in FIG. 3, the warm air chamber 2 includes a first air outlet 200 (first opening) on the left side and a second air outlet 201 (second opening) on the right side in the drawing. The first outlet 200 closes the lower side of the first outlet cylinder portion 200-1 with a plate portion 200a, and forms a first opening on the remaining upper side. Further, the second outlet 201 forms the top of the second outlet cylinder portion 201-1 as a converging taper 201-1a, and the second opening of the bottom portion 201-1d of the second outlet cylinder portion 201-1. A straightening vane 202 is provided which is inclined inward from the end and inclined upward. The straightening vane 202 is provided in a direction orthogonal to the blowing direction of the second outlet 201, and both ends thereof reach both side surfaces 201-1b and 201-1c of the second blowing cylinder portion 201-1. That is, for example, the straightening vane 202 does not suddenly send the high-temperature combustion gas B flowing through the bottom portion 201-1d of the second outlet cylinder portion 201-1 to the crop of the house H from the second outlet 201, but temporarily. Guard and drive towards the first outlet 200, preferably by this first outlet 200, bring the hot combustion gas B to a lower temperature (lower) to the optimum temperature (optimal temperature). It is a structure that plays a role of sending to the crops of House H and also to the height of the first outlet 200. Therefore, as described above, the first outlet 200 is opened on the upper side (upper side) of the first outlet cylinder portion 200-1. At the first outlet 200, a part of the air in the house H sucked through the air intake hole 105 is connected to the front side of the can body 100 (in FIG. 2, the left side 100a in the same direction) and the headquarters of the burner 101. Since the relatively low temperature air passing through the gap 3 reaches the inside of the warm air chamber 2 via the upper opening 1a and the lower opening 2a, it is mixed with the high temperature combustion gas B in this space region A1 and the temperature is adjusted. It goes down and can be sent to the crops of House H as so-called combustion gas B at an appropriate temperature. Another means of using the combustion gas B at an appropriate temperature is a structure in which the first outlet 200 is opened above the first outlet cylinder portion 200-1 to gain the residence time of the high-temperature combustion gas B in the space region A1. (The timing of lowering the temperature of the high-temperature combustion gas B remaining in the warm air chamber 2 is planned).

In the figure, 107 indicates a flame. Further, the movable straightening vane 202 of FIG. 4 has a structure in which the lower end portion on the second opening side is pivotally supported by the bottom portion 201-1d, and has a structure of approximately 90 ° via a mechanism such as manual or automatic. It is movable within the range. This allows the proper temperature (and / or proper amount) of CO2 to be sent to the crops in House H.

Hereinafter, the flow of air C, combustion gas B, CO2, etc. flowing through the main body 1 will be described. When the burner 101 is turned on, the flame 107 is injected into the can body 100, and the combustion gas B is generated in the can body 100. At the time of combustion, the air X in the house H sucked from the air intake hole 105 rises after reaching the space region A1 by the blower 103, and becomes the combustion gas B discharged from the discharge pipe 102. It mixes and lowers the temperature, converts it into CO2 at an appropriate temperature, and guides it to the warm air chamber 2 via the upper opening 1a and the lower opening 2a. After that, the air is blown into the warm air chamber 2 in an accelerated state from the first air outlet 200 and the second air outlet 201.

In the warm air chamber 2, the CO2 sent from the lower opening 2a is sent to the first outlet 200 and the second outlet 201, respectively. As described above, the first outlet 200 and the second outlet 201 are sent. And the difference in height (the first outlet 200 is high "with plate 200a", while the second outlet 201 is low "with taper 201-1a") and the difference in position ( By utilizing the difference in opening height) and the installation of the straightening vane 202, CO2 of the same temperature is blown out substantially evenly from the first outlet 200 and the second outlet 201, and preferably, the air is blown substantially evenly. Ensure speed and / or substantially equal air flow.

The optimum temperature of CO2 is supplied to the crops of House H when necessary.

The sensor is provided at an appropriate position in the house H, but is not shown.

Each of the above-mentioned structures is a description of a preferred example of the present invention. Therefore, the present invention is not limited to the above-described embodiments, and a structure in which a part of the configuration is changed within the scope of the invention, a structure capable of achieving the same features and effects, and the like are within the scope of the present invention.
