  However, especially for small boats such as pleasure boats, even if there is a dedicated power source to obtain the power necessary for navigation, it is used for the operation of portable air conditioners as described above in terms of electrical connector equipment and capacity. In many cases, an inboard power source (external power source) that can be used is not equipped. For this reason, in the conventional portable air conditioner that uses the input power from the external power source terminal as the driving power of the device, for example, in a small ship under hot weather Despite the desire to use air conditioners when navigating and navigating in cold winds, there are many cases where it is necessary to give up the use of this, in terms of functionality and versatility. There was a problem.

  In order to solve this problem, it is conceivable to provide a portable air conditioner with a battery accommodating portion and operate the device with the output power of the battery accommodated in the battery accommodating portion. Due to changes in usage conditions such as changing the consumption rate of cold and warm heat depending on the season and weather, the battery power still remains considerably when the cold storage and warm heat of the heat storage agent is used up, When battery power is used up, there is still a significant amount of cold energy and thermal energy remaining in the heat storage agent, and there is an excess space in the device that does not contribute to the operation of the device due to the excess of the battery power or the excess of the cold or hot energy. As a result, the device value as a portable device (that is, the value of how high device performance can be exhibited in a portable device whose size is limited) Problem to become a low devices occurs.

  And in particular, when it is possible to switch between a battery operation mode in which the device is operated with the output power of the battery accommodated in the battery accommodating portion and an external power supply operation mode in which the device is operated with the input power from the external power supply terminal, When the external power supply operation mode is selected, the entire battery accommodating portion becomes an occupied space that is not involved in the operation of the device that merely accommodates the battery, so that the device value as the portable device described above is further reduced. Become a thing.

  In view of this situation, a main problem of the present invention is to effectively solve the above-described problems by adopting a rational device configuration for configuring a portable air conditioner.

[1] A first characteristic configuration of the present invention relates to a portable air conditioner,

In the state where the battery is accommodated in the battery accommodating portion and the heat storage agent is accommodated in the heat source accommodating portion, the output power of the battery accommodated in the battery accommodating portion is used as the driving power of the device, and the stored cold heat of the heat accumulating agent accommodated in the heat source accommodating portion Or the battery operation mode in which the generated air is generated by the air adjusting means using the retained heat, and the generated air or the generated air is sent out by the fan,
In a state where the heat storage agent is accommodated in both the battery accommodating portion and the heat source accommodating portion and the battery accommodating portion is an extension portion of the heat source accommodating portion, the input power from the external power supply terminal is used as the driving power of the device, and the battery accommodating portion and With the external power supply operation mode in which cold air or hot air is generated by the air adjusting means using the retained cold or retained heat of the heat storage agent accommodated in both of the heat source accommodating portions, and the generated cold air or the generated warm air is sent out by a fan. Mode switching means for switching is provided.

  In other words, according to the first feature configuration, the portable air conditioner is operated in the battery operation mode even in a situation where there is no external power source that can be used for the operation of the portable air conditioner (for example, on a pleasure boat or campsite). You can get a feeling of cooling by sending cool air and a feeling of heating by sending warm air, and if there is an appropriate external power supply, you can select the external power supply operation mode without requiring battery preparation. By operating the portable air conditioner, it is possible to obtain a feeling of cooling by the sent cool air and a feeling of heating by the sent warm air. In this respect, the portable air conditioner can be made excellent in functionality and versatility.

  In addition, in the external power supply operation mode in which the device is operated by the input power from the external power supply terminal, a state in which the heat storage agent is stored in the battery storage portion instead of an unnecessary battery and the battery storage portion is used as an extension portion of the heat source storage portion. Therefore, since the cold air or hot air is generated using the stored cold heat or the stored hot heat of the heat storage agent stored in both of the battery storage unit and the heat source storage unit, the battery storage is performed under the condition that there is no use time limit due to the battery capacity. The usable time of the device can be extended by the amount of cold or retained heat stored in the heat storage agent, and the battery storage can be used effectively in the operation of the device even in the external power supply operation mode. Thus, it is possible to obtain a device having a high device value as a portable device (how much high device performance can be exhibited in a portable device in which the size of the device is limited).

  In the implementation of the first characteristic configuration, various materials such as ice, dry ice, and other latent heat storage agents can be adopted as the heat storage agent for cooling, and hot water, heated ceramics, etc. as the heat storage agent for heating Various types of solids and latent heat storage agents can be used.

Various types of systems such as a system, a system that cools or heats air with a heat exchanger that allows a circulating heat medium to flow with the heat storage agent, and generates cold air or hot air can be adopted.

[2] The second characteristic configuration of the present invention specifies an embodiment suitable for the implementation of the first characteristic configuration.
As the mode switching means, a power supply switching means for switching between a state in which the output power of the battery accommodated in the battery accommodating portion is the driving power of the apparatus and a state in which the input power from the external power supply terminal is the driving power of the apparatus. While providing
Communication switching means for switching between a state in which the battery housing part and the heat source housing part are separated from each other by the partition wall part and a state in which the partition by the partition wall part is released and the battery housing part and the heat source housing part are in communication with each other It is in the point which is provided.

  In other words, in this second characteristic configuration, each battery is stored in a state in which the battery and the heat storage agent are isolated from each other by switching to the non-communication state in which the battery housing portion and the heat source housing portion are partitioned by the partition wall by switching by the communication switching means. The battery operation mode is realized by setting the output power of the battery accommodated in the battery accommodating portion to drive power of the apparatus by switching by the power source switching means.

  Moreover, the battery accommodating part and the heat source accommodating part are substantially made into one accommodating part by making the battery accommodating part and the heat source accommodating part into a communication state in which the partition by the partition wall is released by switching by the communication switching means. Thus, the external power supply operation mode is realized by allowing the heat storage agent to be stored in both the storage units and setting the input power from the external power supply terminal as the drive power of the apparatus by switching by the power supply switching means.

  And according to this 2nd characteristic structure, since a battery accommodating part and a heat source accommodating part are substantially made into one accommodating part by communication in external power supply operation mode, in each of these battery accommodating part and a heat source accommodating part In the external power supply operation mode for storing the heat storage agent, as in the case of the battery operation mode, the battery storage unit and the heat source storage can be performed only by taking out the stored cold heat or the stored heat of the heat storage agent stored in the heat source storage unit from the heat source storage unit. Means for taking out the stored cold heat or the stored hot heat of the heat storage agent stored in the storage section from both of the sections, and thereby taking out the stored cold heat or stored heat of the heat storage agent stored in the heat source storage section from the heat source storage section; Separately, compared with the additional equipment for external power supply operation mode, the structure of the device is compared with that for taking out the stored cold heat or stored heat of the heat storage agent stored in the battery storage section from the battery storage section. And it can be based, together may in inexpensive equipment cost, portability of the portable air conditioner by compact and lightweight can be enhanced.

  In the implementation of the second characteristic configuration, the power supply switching means and the communication switching means may be either individually switched by different operations on them or switched by both common operations.

  Further, in order to release the partition by the partition wall by the communication switching means in the external power supply operation mode and to make the battery housing portion and the heat source housing portion communicate with each other, for example, a method of removing the partition wall portion or a communication port formed in the partition wall portion. Various partition releasing methods such as a method of opening the communication port by operating the obturator can be adopted.

  In addition, the power supply switching means is automatically operated in conjunction with the connection and release of the terminal with respect to the battery, or in conjunction with the storage of the battery in the battery housing and the removal of the battery from the battery housing. It is also possible to automatically switch the operation in conjunction with the connection and disconnection of the external power supply terminal with respect to the external power supply.

[3] A third characteristic configuration of the present invention relates to a portable air conditioner,

  In addition, in a form in which one part of the battery housing part and the heat source housing part is used as the other extension part, the volume of the battery housing part and the volume of the heat source housing part are increased and decreased in a contradictory manner. The volume ratio between the battery and the heat source container can be changed, and by changing the volume ratio, both the capacity of the battery accommodated in the battery container and the amount of the heat storage agent accommodated in the heat source container are ensured as large as possible. However, it is possible to make adjustments so that there is no excess or deficiency in the usage status of the device at that time.

Various systems, such as a system that generates cold air or hot air by cooling or heating air with a heat exchanger that allows a circulating heat medium to flow between the heat storage agent and the heat storage agent, can be employed.

  In addition, in the implementation of the third characteristic configuration, the output power of the battery accommodated in the battery accommodating portion is used as the driving power of the device, and the air conditioning is performed using the retained cold or retained heat of the heat storage agent accommodated in the heat source accommodating portion. The battery operation mode in which the cool air or the warm air is generated by the means and the generated cool air or the generated warm air is sent out by the fan, and the heat storage stored in the heat source storage unit using the input power from the external power supply terminal as the drive power of the device A mode switching unit is added to generate cold air or hot air using the air conditioning means using the stored cold or warm temperature of the agent, and to switch to the external power supply operation mode in which the generated cold air or generated hot air is sent out by a fan. Thus, higher functionality and versatility may be obtained.

  In the implementation of the third characteristic configuration, the change in the volume ratio between the battery housing unit and the heat source housing unit by the volume ratio changing unit may be a stepwise change or a continuous change.

  In other words, according to the fifth feature configuration, for example, when carrying the device, the blower side case and the accommodating portion side case are connected to carry them as a single portable device case, and the device can be used. In some cases, the connection between the blower side case and the housing part side case can be released, and the blower side case and the housing part side case can be installed at locations suitable for the respective installations. While obtaining high portability as an effect of the characteristic configuration, it is possible to make the device more excellent in functionality and versatility in terms of use of the device.

  In the implementation of the fifth characteristic configuration, the air adjusting means, the mode switching means, or the volume ratio changing means may be provided in either the air blowing side case or the accommodating portion side case, and the air blowing side case and the accommodating portion. The interior may be divided into a side case.

[6] The sixth characteristic configuration of the present invention specifies an embodiment suitable for the implementation of any of the first to fifth characteristic configurations,
The air conditioning means includes a heat transfer medium housed in a heat source housing section together with a plurality of heat storage containers enclosing a heat storage agent, or a heat source housing section in a heat source housing section and a battery housing section together with a plurality of heat storage containers encapsulating a heat storage agent. It is the point which has the structure which produces | generates cold wind or warm air using the holding | maintenance cold heat or holding | maintenance heat of the heat-medium liquid accommodated in both the expansion parts.

  In other words, in the sixth feature configuration, the heat transfer liquid is cooled or heated by exchanging heat with the heat storage agents in the plurality of heat storage containers containing the heat transfer liquid, and the retained heat of the cooled heat transfer liquid or the heated heat transfer medium is stored. Cold air or hot air is generated using the retained heat of the liquid (that is, the cold or warm heat originally stored in the heat storage agent).

  And according to this 6th characteristic structure, since a thermal storage agent is divided and enclosed with a plurality of thermal storage containers, even if there is a state where a thermal storage agent turns into a liquid, a thermal storage agent is in the device at the time of carrying of the device. It can be effectively prevented from shaking greatly, and since the heat transfer fluid is stored with multiple heat storage containers, the heat transfer solution can be stored in a small amount, and the heat transfer solution can be used when carrying the device. Can be prevented from shaking greatly in the apparatus, which makes it easier to carry the apparatus and further enhances the portability of the apparatus.

[7] The seventh characteristic configuration of the present invention specifies an embodiment suitable for the implementation of the sixth characteristic configuration.

  That is, according to the seventh feature configuration, it is possible to prevent the heat storage container from rattling when the device is carried by positioning by the container arrangement structure, and in combination with the effect of the sixth feature configuration, Carrying can be further facilitated, and the portability of the device can be further enhanced.

  In the implementation of the seventh characteristic configuration, the container arrangement structure is different from the heat source container or the heat source container and the additional part of the heat source container in the battery container in place of the heat storage container. It is desirable to have a structure that can directly accommodate the heat storage agent.

[8] The eighth characteristic configuration of the present invention specifies an embodiment suitable for the implementation of any of the first to seventh characteristic configurations,

In other words, a terminal storage means is provided that can be freely switched to a storage release state that is exposed in the battery housing.

  That is, according to the eighth characteristic configuration, when the battery is accommodated in the battery accommodating portion in the battery operation mode in the implementation of the first characteristic configuration, the terminal accommodating means is brought into the storage release state, and the battery accommodating portion In the external power supply operation mode, when the battery housing part is an extension part of the heat source housing part, the terminal storage means is placed in the stowed state, while the battery connection terminal in the battery is in an exposed state that can be connected to the housing battery. Thereby, the battery connection terminal in the battery accommodating part can be stored hermetically and contact with the heat storage agent accommodated in the battery accommodating part can be prevented.

  Similarly, in the implementation of the third characteristic configuration, in a state where a part of the battery housing part is not an extension part of the heat source housing part, the terminal storage means is released from the storage state, and that part of the battery housing part (still heat source The battery connection terminal of the part that is not an additional part of the housing part is in an exposed state that can be connected to that part of the battery, whereas a part of the battery housing part is an additional part of the heat source housing part Then, by putting the terminal storage means in the retracted state, the battery connection terminal of that portion (additional portion of the heat source accommodating portion) in the battery accommodating portion is hermetically stored, and contact with the heat storage agent accommodated in that portion is made. Can be prevented.

  That is, due to these, while adopting a configuration in which the battery housing part or a part thereof is used as an extension part of the heat source housing part, such as early deterioration of the battery connection terminal due to contact between the battery connection terminal and the heat storage agent Various inconveniences can be effectively prevented.

  FIG. 1 shows a state in which the portable air conditioner X is used on a pleasure boat. As shown in FIG. 2, in this portable air conditioner X, 1 is a rectangular parallelepiped portable device case. The inside of the device case 1 is partitioned into an air adjustment unit 2, a battery housing unit 3, and a heat source housing unit 4 in the longitudinal direction.

  On one end surface portion in the longitudinal direction of the portable device case 1, an air inlet 5 for taking in air OA outside the case is formed in the air adjusting portion 2 arranged on one end side in the case longitudinal direction. A fin tube type heat exchanger 6 for exchanging heat of the intake air OA from the intake port 5 with the heat transfer fluid W is provided in close proximity to the intake port 5 and the adjusted air that has passed through the heat exchanger 6 An air chamber 7 for receiving SA (that is, intake air OA whose temperature is adjusted by heat exchange with the heat transfer fluid W) is formed.

  In addition, the air adjusting unit 2 is supplied with an air supply chamber 9 communicated with two air outlets 8 formed on the upper surface of one end in the longitudinal direction of the portable device case 1, and adjusted air SA in the air chamber 7. A fan 10 that is supplied to the air chamber 9 and discharged from the air outlet 8 is internally provided, and further, heat is supplied through the circulation path 11 between the heat source housing 4 and the heat exchanger 6 disposed on the other end side in the longitudinal direction of the case. A circulation pump 12 that circulates the liquid medium W and a controller 13 that controls operation of the apparatus are housed.

  Of the upper surface portion of the portable device case 1, the portions corresponding to the heat source accommodating portion 4 disposed on one end side in the case longitudinal direction and the battery accommodating portion 3 disposed in the center portion in the case longitudinal direction are provided with these heat source accommodating portions. 4 and the battery housing portion 3 are provided with a common opening / closing lid 14, and by opening the opening / closing lid 14, the battery 15 (storage battery in this example) for the battery housing portion 3 is opened as shown in FIGS. 3 and 4. An operation for putting in and out the heat storage container 16 with respect to the heat source housing 4 is performed.

  A flat rectangular parallelepiped shaped heat storage container 16 accommodated in the heat source accommodation unit 4 is filled with a latent heat storage agent Z for cooling having a specific heat and viscosity larger than water and having a melting point near 0 ° C. , Together with a plurality of heat storage containers 16 in a state where the internal latent heat storage agent Z is solidified by cooling, a heat transfer liquid W (in this example, heat exchange with the latent heat storage agent Z in the heat storage containers 16 via the container wall) Water).

  That is, in this portable air conditioner X, the heat cooled by the heat exchange with the latent heat storage agent Z by operating the circulation pump 12 and the fan 10 using the output power of the battery 15 accommodated in the battery accommodating unit 3 as drive power. The medium liquid W is circulated through the heat exchanger 6, the intake air OA is cooled by the heat exchanger 6 by heat exchange with the cooling heat medium liquid W, and the adjusted air SA (that is, cold air) after the cooling is blown. It sends out from the outlet 8.

  An air guide hose 17 can be connected to each of the two air outlets 8. By connecting an air guide hose 17 having an appropriate length to the air outlet 8, the cool air SA ( The adjusted air) is blown out from the tip of the air guide hose 17 in a required direction, or can be guided to a required location.

  Further, a cap 18 that closes the air outlet 8 can be attached to the air outlet 8, so that the air guide hose 17 is connected to only one air outlet 8 as shown in FIG. 8 can be selected as appropriate, such as a usage mode in which the cap 18 is closed as a spare, or a usage mode in which the wind guide hose 17 is connected to both the outlets 8 and the cold air SA is sent out from both the outlets 8. It is.

  An external power supply terminal 20 connected to a general commercial power source, which is an external power supply, is provided on one side surface of the portable device case 1 via a detachable connection cord 19, and one end of the portable device case 1 is provided. At the upper part of the surface portion, an operation unit 25 is provided in which an operation switch 21, a strength adjustment tool 22, a battery lamp 23, and an external power lamp 24 are arranged on a case wall portion that is inclined upward.

  When the operation switch 21 is turned ON when the external power supply terminal 20 is not connected to a general commercial power supply, the controller 13 uses the output power of the battery 15 accommodated in the battery accommodating portion 3 as the driving power of the apparatus. The operation of the apparatus is started with the power supply circuit automatically switched to the power supply state, and the battery lamp 23 is lit. In this battery power supply state, the circulation pump 12 and the fan 10 are driven by the output power of the battery 15. Cold air S is generated and sent out during operation.

  In addition, when the operation switch 21 is turned ON with the external power supply terminal 20 connected to the general commercial power supply, the controller 13 receives input power from the external power supply terminal 20 (that is, power supplied from the general commercial power supply). The operation of the apparatus is started in a state where the power supply circuit is automatically switched to the external power supply state in which the drive power of the apparatus is used, and the external power supply lamp 24 is lit. In this external power supply state, the external power supply terminal 20 The cold air SA is generated and sent out by the operation of the circulation pump 12 and the fan 10 by the input power from.

  The controller 13 is configured to blink the battery lamp 23 when the voltage of the battery 15 in the battery housing unit 3 drops to the threshold voltage (that is, the remaining power of the battery 15 decreases) in the battery power supply state. It is.

  The strength adjusting tool 22 adjusts the output of the apparatus. When the strength adjusting tool 22 is operated, the controller 13 controls the outputs (rotations) of the circulation pump 12 and the fan 10 in accordance with the operation. Thus, the amount of air sent out of the cold air SA is increased or decreased while keeping the temperature of the cold air SA substantially constant.

  The battery housing portion 3 and the heat source housing portion 4 are formed by partitioning the inside of the heat insulating tank 26 formed in the portion of the portable device case 1 excluding the air adjustment portion 2 into two regions by the partition wall 27. In addition, the partition wall 27 that is a partition wall between the battery housing unit 3 and the heat source housing unit 4, the tank wall of the heat insulating tank 26, and the opening / closing lid 14 that is a lid for the heat insulating tank 26 are each subjected to heat insulation treatment.

  In addition, a communication port 28 that allows the battery housing 3 and the heat source housing 4 to communicate with each other is formed in the lower portion of the partition wall 27, and a closing tool 29 that closes the communication port 28 can be attached to the communication port 28. It is.

  That is, when the battery 15 is housed in the battery housing 3 and the heat storage container 16 and the heat transfer fluid W are housed in the heat source housing 4, the communication port 28 is closed by the closing tool 29. The battery housing part 3 and the heat source housing part 4 are partitioned in a watertight manner by the partition wall 27 so as to prevent the heat medium liquid W from entering the battery housing part 3.

  On the other hand, when the apparatus 15 is operated in an external power supply state in which the input power from the external power supply terminal 20 is the driving power of the apparatus and the battery 15 is not required, the battery 15 is replaced as shown in FIGS. The battery storage unit 3 also stores the heat storage container 16 together with the heat transfer fluid W so that the battery storage unit 3 can be used as an extension of the heat source storage unit 4.

  At this time, the communication medium 28 between the battery housing unit 3 and the heat source housing unit 4 is opened by opening the communication port 28 of the partition wall 27 and allowing the battery housing unit 3 and the heat source housing unit 4 to communicate with each other at the lower part. The heat between the heat source housing portion 4 and the heat exchanger 6 by the circulation pump 12 is obtained by making the battery housing portion 3 and the heat source housing portion 4 substantially one heat source housing portion. By extracting the retained cold heat of the latent heat storage agent Z in the heat source storage unit 4 by circulation of the liquid medium W, the stored cold heat of the latent heat storage agent Z in the battery storage unit 3 can be extracted together.

  That is, in this portable air conditioner, the following three operation modes (A) to (C) can be alternatively selected.

  (A) The battery 15 is housed in the battery housing 3 and the heat storage container 16 (in other words, the latent heat storage agent Z) and the heat transfer fluid W are housed in the heat source housing 4 and the output power of the battery 15 is supplied to the device. By using the battery power state as the driving power of the battery 15 and operating the circulation pump 12 and the fan 10 with the output power of the battery 15, the cold air SA is generated using the cold heat stored in the latent heat storage agent Z in the heat source housing 4. Battery operation mode for sending out the generated cold air SA (see FIGS. 3 and 4).

  (B) In a state in which the heat storage container 16 (latent heat storage agent Z) and the heat transfer fluid W are stored in both the battery storage unit 3 and the heat source storage unit 4, the input power from the external power supply terminal 20 is used as the drive power of the device. By taking the external power supply state and operating the circulation pump 12 and the fan 10 with the input power from the external power supply terminal 20, the stored cold heat of the latent heat storage agent Z in both the heat source storage unit 4 and the battery storage unit 3 is reduced. An external power supply operation mode in which the cold air SA is generated and the generated cold air SA is sent out (see FIGS. 5 and 6).

  (C) While the battery 15 is housed in the battery housing 3 and the heat storage container 16 (latent heat storage agent Z) and the heat transfer fluid W are housed in the heat source housing 4, the input power from the external power supply terminal 20 is By taking the external power supply state as the driving power and operating the circulation pump 12 and the fan 10 by the input power from the external power supply terminal 20, the cold air SA is generated using the cold heat stored in the latent heat storage agent Z in the heat source housing unit 4. A battery storage operation mode for generating and sending out the generated cold air SA.

  In other words, in this portable air conditioner, by operating in the battery operation mode, the device can be used even in a situation where there is no appropriate external power source that can be used for the operation of the device (for example, on a pleasure boat or campsite).
