For example, the inventor wants to solve a problem that a worker working in a high-temperature environment such as a tropical region where the temperature exceeds 40 ° or a steelworks, for example, damages to the lungs and exhaustion of physical strength caused by inhaling high-temperature air. Found that there is. If you continue to inhale air at high temperatures (for example, 40 ° to 60 °), humans will feel uncomfortable and uncomfortable with the airways and lungs, and will feel very tired. In some cases, serious damage or sequelae are caused to the human body.
The present invention has been made to solve the problems caused by sucking high-temperature air that could not be solved by the conventional techniques such as the above-described conventional cooling clothing.
Recognition of such a problem is not disclosed in the prior art.

The objective of this invention is providing the mask part provided with the cooling function by a circulating liquid.
An example of a specific purpose is as follows.
(A) To provide a mask portion having a cooling function capable of lowering the temperature of air actually taken in by an operator or the like wearing the mask portion with a relatively simple configuration.
(B) To provide a mask unit having a cooling function having a device for improving the cooling function when the temperature of air taken in by an operator or the like is lowered.
In addition, the subject of invention other than having described above, its solution means, and its effect are demonstrated in detail in description in the specification mentioned later.

Although the present invention can be expressed in many ways, for example, typical ones are configured as follows. In each of the following inventions, each symbol is shown as an example for easy understanding of the correspondence with the embodiment described later, and each component of the present invention corresponds to the configuration related to the symbol described in the embodiment. It goes without saying that it is not limited.
As described above, the present invention has been made by discovering that the present inventor is a technology that is eagerly desired to reduce discomfort and pain of workers who inhale high temperature air. It is. Furthermore, the present invention has been made by a continuous search for a configuration that can easily and inexpensively solve the above problems. It is clear that there is no invention where the problem is not recognized.

A characteristic configuration of the present invention for solving the above problems will be described.
The mask portion 1 having the cooling function by the circulating liquid of the present invention is provided on the cup portion 2 covering at least both the mouth and nose regions, and on the cup portion 2 to a person wearing the cup portion 2. An intake portion 5 that enables intake from the cup portion 2, a cooling liquid passage 13 that exists in the cup portion 2 and in which a liquid such as water circulates, and a shape that increases the heat exchange area of the liquid passage 13 And a liquid path constituent member 8 configured as described above (claim 1).
In the present invention, the liquid path constituent member and the cup part may be configured separately, or the cup part may be configured by the liquid path constituent member itself.
Furthermore, various materials, such as a synthetic resin and a metal, can be adopted as a material constituting the liquid path constituent member.

With this configuration, since a circulating liquid such as water is used, the air in the cup portion can be strongly cooled by taking more heat than the heat exchange of a gas such as a cooling fan. Further, since the heat exchange area of the liquid path can be increased by providing the liquid path constituting member, the cooling action by the liquid can be improved. Furthermore, since heat exchange is performed using the circulating liquid, it can be stably cooled for a long time.
In addition, since the liquid path constituting part is provided in the mask part, the operator can suck the low temperature air before it is warmed by the outside air by heat exchange.
One of the features of the present invention is that when the mask portion is cooled, a liquid is used at room temperature and the liquid is circulated.
In the structure of the conventional patent document 3, when the dry ice in the dry ice storage container is used up, it is necessary to supply new dry ice, which is troublesome and has a problem of high cost. On the other hand, in the present invention, since a liquid such as water circulates, the refrigerant can be used repeatedly, so that the mask portion can be cooled at a low cost.
Moreover, in the structure which applied the structure of patent document 3 to the mask part as it is, oxygen dioxide after dry ice vaporizes will fill a mask part, and since an operator becomes insufficient oxygen, from safety. Is also not preferable.

  Furthermore, as an essential problem, when a gas that is not liquid is used, the heat capacity of the gas is significantly smaller than that of a refrigerant that is liquid at room temperature, and the mask portion may not be cooled to a practical level. . For example, when considering a moving worker engaged in construction work in a high-temperature area, if the configuration is such that air that is cooler than the outside air temperature is supplied to the mask part worn by the worker, the heat is heavy and heavy. It is necessary to wear an exchange device (for example, an air conditioner and its outdoor unit can be understood) and its driving power source. If the fluid to be supplied is a gas configuration, the worker must wear the heavy heat exchanger and its power supply on the body, and it is easy to understand that this is impossible in reality. It can be done.

In the present invention, for example, as shown in FIG. 7, an opening 12 is provided in the liquid path constituent member 8 so as to avoid the liquid path 13, and air is sucked from the intake section 5 through the liquid path constituent member 8. It is configured to be possible (claim 2).
If it is this structure, even if it is the structure which provided the liquid path structural member which has the surface and shape which block | inhale inhalation in a cup part, it becomes possible to deliver air to an operator's nose and mouth via an opening part.

In the present invention, the liquid passage 13 is constituted by the liquid pipe 13 (Claim 3).
In the present invention, for example, as shown in FIG. 4, the liquid path constituting member 8 includes a plurality of concavo-convex portions 11 on at least one of the face 7 side and the outer side of the wearer, and intake air from the intake portion 5. And the shape of the liquid tube 13 in the cup portion 2 is maintained by engaging the plurality of concavo-convex portions 11 so as to hold the liquid tube 13. (Claim 4 dependent on claim 3).

In the present invention, for example, as shown in FIG. 6, the configuration of the liquid path constituent member 8 and the liquid path 13 is configured by an integral molded product 14 such as a synthetic resin, and the molded product 14 is connected to the cup portion 2. (Claim 5).
As described above, the configuration of “providing the molded product in the cup portion” includes a configuration in which the molded product is accommodated in the cup portion and a configuration in which the molded product itself is the cup portion.
With this configuration, the liquid path can be arranged so as to increase its heat exchange area simply by providing an integral molded product in the cup portion, and the liquid pipe is swung or meandered and fixed. Compared to the above, the manufacture of the mask portion is simplified.

In the present invention, for example, as shown in FIGS. 8 and 9, when viewed from the direction L facing outward from the face 7 on which the cup portion 2 is mounted, the liquid path constituting member 8 is disposed on the cup portion 2. The present invention is characterized in that it is configured by a side surface portion 24 existing on the side surface side, and the liquid path 13 is swung and supported by the side surface portion 24 a plurality of times (Claim 6).
If it is this structure, a liquid path structure member can be comprised by the cheap and simple structure of turning and supporting a liquid path in the side part of a cup part in multiple times.

In the present invention, for example, as shown in FIG. 5, a liquid container 20 that stores the liquid for cooling and a pump 19 that circulates the liquid in the liquid path 13 are provided. 7).
In the present invention, the intake section 5 is composed of a functional sheet having various filter functions (claim 8).
In the present invention, the intake section 5 is constituted by a member provided with a plurality of intake openings 28 (Claim 9).

In the present invention, for example, as shown in FIG. 10, the liquid path constituting member 8 has a base body 34 which is a spiral shape or a concentric circular shape and is made of an elastically deformable material. Has a gap 30 between spirals or concentric circles, and a liquid passage 13 provided in the base 34 (claim 10).
In the present invention, for example, as shown in FIG. 11, the liquid path constituting member 8 is fixedly provided in the liquid path 13 and a flat sheet-shaped member 40 in which a plurality of the liquid paths 13 are formed. And a fiber member 41 having flexibility, and the fiber member of the fiber member 41 intersects at least the vertical direction of the sheet member 40 (claim 11).
If it is this structure, a heat exchange area can be enlarged by forming a some liquid path in a flat sheet-like member. In addition, even when the sheet member is deformed so as to bend by being fixed in the liquid passage in a state where the fiber member intersects in the vertical direction, a good liquid can be obtained through the gap formed by the intersection of the fiber member. It can be set as the liquid path which can ensure the flow of.

In the present invention, for example, as shown in FIG. 12, the liquid path constituting member 8 includes a metal base 51 having high thermal conductivity, the liquid path 52 formed in the metal base 51, and the metal. It has the uneven part 53 for heat exchange for liquids which increases the heat exchange area provided in manufacture base 51, (claim 12).
With this configuration, a metal base having a higher thermal conductivity than a member such as a synthetic resin, such as a metal such as copper or aluminum, is used as the liquid path constituent member so that the entire liquid path constituent member is in a low temperature state. Therefore, cooling efficiency can be increased.
In the present invention, for example, as shown in FIG. 16, an intake passage 57 formed in the metal base 51 is provided, and the vertical uneven portion for air (for example, the vertical uneven portion shown in FIG. 13) is provided in the intake passage 57. The heat exchange area is increased by providing the portion 69, etc. (Claim 13).
If it is this structure, the air which flows through an intake passage with the metal base | substrate which fell in temperature will be cooled strongly, and the temperature of the air inhaled from a nose or a mouth can be lowered efficiently.

The air intake structure in the mask portion 1 is configured so as to be inhaled. (Claim 14).
With this configuration, it is possible to remarkably reduce the intake of air having a high external temperature directly from the mouth or nose through the mask portion, so that the temperature of the intake air can be efficiently reduced.

In the present invention, for example, as shown in FIG. 16, the intake passage 57 of the mask portion 1 and the exhaust passage 58 communicating with the exhaust portion 66 of the mask portion 1 are configured as separate passages, respectively, A check valve 59 is provided that suppresses mixing of air sucked 57 and human exhaust discharged from the exhaust passage 58. (Claim 15).
With this configuration, by providing a check valve, it is possible to suppress mixing of the air sucked into the intake passage and the human exhaust discharged from the exhaust passage, so that the warm human exhaust and the cooled intake It can reduce that cooling efficiency falls by mixing.
In the present invention, the liquid path constituting member 8 having the liquid path 52 and the intake path 57 is configured to include at least one casting (claim 16).
If it is this structure, the manufacturing cost in the case of comprising a liquid path structural member can be reduced.

In the present invention, the constituent material of the mask part 1 is made of a material lower than the thermal conductivity of the metal base 51, and the metal base 51 is not directly exposed to the outside air due to the presence of the constituent material of the mask part 1. Thus, the liquid path constituting member 8 is arranged in the mask portion 1 (Claim 17).
With this configuration, the high temperature outside air and the liquid path constituent member are partitioned in terms of heat conduction by the low thermal conductivity constituent material, and the temperature of the liquid path constituent member is increased by the high temperature outside air. Can be suppressed.
In the present invention, for example, as shown in FIGS. 12 to 15, the liquid passage 52 and the intake passage 57 formed in the metal base 51 are both formed at the front and back positions on one plane. (18).
With this configuration, the cooling efficiency can be increased.

The heat exchange uneven part 53 can also form unevenness on the outside of the metal substrate 51. The simplest configuration is a configuration in which a cooling fin or the like (not shown) provided in the engine is provided on the metal base 51 itself. Even in this configuration, it is preferable to provide a cover member (not shown) that covers the cooling fins or the like so as to control the flow of air sucked from the air intake portion of the mask portion. Even in this case, the cover member has an intake opening (not shown). This cover member may be made of synthetic resin.

The preferred configuration of the present embodiment proposes an efficient configuration for lowering the intake air as compared to a configuration in which a cooling fin or the like is simply provided.
Specifically, first, there is a point that an intake passage 57 is formed in the metal base 51 in addition to the liquid passage 52, and a heat exchange uneven portion 53 is formed in the intake passage 57.
With regard to the configuration of the liquid passage 52, as shown in FIG. 12, a liquid inlet 55 and a liquid outlet 56 for cooling are formed in a first metal flat plate 54 such as a casting, and the liquid communicating the liquid inlet 55 and the liquid outlet 56 is formed.

As shown in FIG. 16, the check valve 59 is often composed of an intake side check valve 59 and an exhaust side check valve 59. Specifically, a check valve 59 is employed that is configured to easily open in the direction in which intake air is sucked from the intake passage 57 and has a function of preventing breathing into the intake passage 57 from entering the intake passage 57.
Such a check valve 59 is, for example, a communication port (not shown) that faces the connection portion 67 of the intake passage 57 with respect to the space of the connection portion 67 that communicates with the intake passage 57 and the exhaust passage 58 that communicate with the mouth and the nose. 1), a configuration in which a seat member or the like that opens in response to a negative pressure state in which air is sucked from the mouth and nose can be exemplified. Similarly, as the check valve 59 provided in the exhaust passage 58, a seat member or the like that opens is connected to the exhaust passage 58 or the connection portion in response to the pressurized state in the connection portion 67 to the extent that air is discharged from the mouth and nose.

Various configurations can be adopted for the mask configuration having the intake passage 57 / intake portion 5 and the exhaust passage 58 / exhaust portion 66. For example, a configuration in which two (or a plurality of) intake portions 5 are provided and an exhaust passage 58 and an exhaust portion 66 are provided near the mouth may be employed. FIG. 15 illustrates two intake portions 5 on one side in a configuration in which the intake portion 5 and the exhaust portion 66 are provided at different positions on the face.
Further, in FIG. 15, the metal base 51 is fixed to the mounting portion 70 without a gap. That is, the attachment part 70 functions as a substantially ring-shaped attachment base provided in the mask part. Note that the arrows shown in FIG. 15 indicate the flow of intake air.

Hereinafter, the operation of the present embodiment will be briefly described.
In FIG. 16, the high-temperature air sucked from the intake portion 5 of the mask portion 1 is sucked into the intake passage 57 in the metal base 51 from the base-side suction port 63, and the meandering intake air as shown in FIG. The air passes through the passage 57 and is sucked into the intake side opening 60 from the base side communication port 64. An intake-side check valve 59 shown in FIG. 16 is provided at a predetermined position of the intake passage 57 or the connecting portion 67 including the intake-side opening 60, and allows only suction from the operator's nose and mouth.

Further, as described above, since the intake structure is formed in the mask portion so that the air sucked from the intake portion 5 is sucked through the path connected to the intake passage 57 only from the base-side intake port 63, the high temperature The problem of sucking outside air can be solved.

On the other hand, as shown in FIG. 12, the fluid path 52 in the metal base 51 is constantly circulated from the liquid inlet 55 to the liquid outlet 56, so that the low-temperature liquid circulates. Due to the circulation of the liquid, the metallic substrate 51 itself becomes a low temperature state in a short time.
The low temperature state of the metal base 51 is thermally isolated from the high temperature of the outside air by the cup portion 2 of the mask portion 1 being made of a material having low thermal conductivity such as synthetic resin or rubber. Since the low temperature state is continuously maintained, the air can be stably cooled.
In this embodiment, both the liquid passage 52 and the intake passage 57 formed in the metal base 51 as the liquid passage constituting member 8 are configured such that the respective passages are formed on the back and front of one plane. The low temperature state of the liquid passage 52 can be efficiently transmitted to the intake air flowing through the intake passage 57. The advantage of this configuration is that, for example, in a three-dimensional space, the cooling performance is improved as compared with a configuration in which the plane in which the liquid passage 52 extends and the plane in which the intake passage 57 extends are arranged orthogonally, for example, like a T-shape. be able to. The reason is that the configuration in which the liquid passage 52 and the intake passage 57 are formed on the back and front of one plane can improve heat conduction, and the air flowing through the intake passage 57 can be strongly cooled in a short time.
