The air conditioner includes an air conditioning unit (51) that performs an air conditioning operation; a battery (21) serving as a power source of the air conditioning unit (51); and a waste water container (22) which is provided in contact with the battery (21) and stores waste water (26) generated from the air conditioning unit (51) therein.
Description
Technical Field
The present invention relates to an air conditioner using a battery as a power source.
Background
Conventionally, an air conditioner using a battery, particularly a secondary battery, as a power source is known. The battery has temperature characteristics, and is suggested to be used in an appropriate operating temperature range according to the type of the battery in order to exhibit a predetermined performance. On the other hand, the battery generates heat during charging and discharging to become high in temperature, and becomes low in temperature in a cold region, and the battery is likely to deviate from an appropriate operating temperature range depending on the use environment. Therefore, the battery is forcibly cooled or heated as appropriate during charging and discharging of the battery.
For example, in patent document 1, in an electric vehicle, when the temperature of a battery mounted on the electric vehicle is lower than the temperature in the vehicle interior and is equal to or lower than a predetermined temperature set in advance, air in the vehicle interior is supplied to the battery, thereby preventing performance from being lowered due to a decrease in the temperature of the battery. Therefore, the configuration described in patent document 1 includes a temperature sensor that detects the temperature of the battery, a temperature sensor that detects the temperature in the vehicle interior, an air blowing mechanism that supplies air in the vehicle interior to the battery, and a control unit that controls the operation of the air blowing mechanism.

Disclosure of Invention
Technical problem to be solved by the invention
In warm regions and tropical regions other than cold regions, a problem is likely to arise in that the temperature of the battery increases due to heat generation during charge and discharge as compared with a temperature decrease. On the other hand, the structure including the above-described conventional air blowing mechanism is complicated. Therefore, when the conventional air blowing mechanism is applied to a countermeasure for preventing the battery from being heated to a high temperature, the configuration becomes large and the cost increases. In particular, in the case of a portable air conditioner used outdoors such as camping and sports tournaments, the above problem becomes remarkable because of the demand for miniaturization.
An object of one aspect of the present invention is to provide an air conditioner capable of cooling a battery with a simple and low-cost configuration.
Means for solving the problems
In order to solve the above problem, an air conditioner according to an aspect of the present invention includes: an air conditioning unit for performing an air conditioning operation; a battery serving as a power source of the air conditioning unit; and a waste water treatment part which is arranged in contact with the battery and stores waste water generated from the air conditioning part or flows into the air conditioning part.
Effects of the invention
According to an aspect of the present invention, the battery can be cooled with a simple and low-cost configuration.

Detailed Description
[ embodiment mode 1 ]
Embodiments of the present invention will be described below. Fig. 1 is a side view showing an external appearance of an air conditioner 1 according to the present embodiment. Fig. 2 is a schematic diagram showing the internal configuration of the air conditioner 1 shown in fig. 1.
(constitution of air conditioner 1)
As shown in fig. 1, the air conditioner 1 is a portable type device, and has a case 11 covering an outer surface. The case 11 has a side surface, a bottom surface, and an upper surface in a cylindrical shape, and the upper surface is formed in a curved surface shape so as to expand upward. The shape of the case 11 is not limited to the above shape, and is set as appropriate according to the application, for example.
A first intake port 12 is formed in the upper side and a second intake port 13 is formed in the lower side of the side surface of the casing 11. An air outlet 14 is formed at a position opposite to the positions of the first and second air inlets 12 and 13 on the side surface of the casing 11. A heat discharge opening 15 is formed in the upper surface of the case 11.
As shown in fig. 2, a battery 21, a waste water container (waste water treatment unit) 22, an evaporator 23, an evaporator blower fan 24, and a condenser 25 are provided in this order from the lowermost portion to the uppermost portion in the casing 11. The evaporator 23, the evaporator air-sending fan 24, and the condenser 25 are included in an air-conditioning unit 51 described later.
The first air intake port 12 is an opening through which outside air for supplying air to the condenser 25 is taken in. The second air inlet 13 is an opening through which outside air to be blown to the evaporator 23 is sucked. The air outlet 14 is an opening for sending out the cold air or the warm air generated by the air conditioning operation. The heat discharge port 15 is an opening through which heat generated by the air conditioning operation of the air conditioner 1 is discharged.
(positional relationship between the waste water container 22 and the battery 21)
The battery 21 is a secondary battery that can be charged and discharged, and a conventional one can be used. The waste water container 22 is a container for storing waste water 26 generated in the evaporator 23. The water produced in the evaporator 23, i.e., the waste water 26, is received by a waste water tray 27 connected to the waste water container 22. Therefore, the waste water 26 in the waste water tray 27 flows into the waste water container 22 from the waste water tray 27. The waste water container 22 is disposed above the battery 21 in such a manner that the lower surface thereof is in contact with the upper surface of the battery.
The position of the waste water container 22 is not limited to the upper side of the battery 21, and may be disposed so as to contact the outer surface of the battery 21. For example, the waste water container 22 is disposed beside the battery 21 so as to contact the side surface of the battery 21.
(constitution of air-conditioning unit 51 of air-conditioner 1)
Fig. 3 is an explanatory diagram illustrating a cooling operation state of the air-conditioning unit 51 of the air-conditioner 1. Fig. 4 is an explanatory diagram illustrating a heating operation of the air-conditioning unit 51 of the air-conditioning apparatus 1.
The air conditioner 1 includes an air conditioning unit 51 shown in fig. 3 and 4 in detail. The air conditioning unit 51 is constituted by a refrigeration cycle that performs air conditioning operations, i.e., a cooling operation and a heating operation.
In the cooling operation of the air conditioning unit 51, as shown in fig. 3, the high-temperature and high-pressure refrigerant compressed by the compressor 31 is sent to the condenser 25 via the four-way valve 32. In the condenser 25, the air sucked in from the second air inlet 13 by the condenser fan 33 is sent toward the condenser 25 to be cooled, and the refrigerant is liquefied. The air having passed through the condenser 25 is discharged from the heat discharge port 15 in a state including heat released by liquefaction of the refrigerant in the condenser 25.
The liquefied refrigerant is injected into the evaporator 23 through a minute nozzle hole of the expansion valve 34 and is vaporized at a time. The vaporized refrigerant takes heat from the periphery of the evaporator 23, and the evaporator 23 is cooled. The air taken in from the first air intake port 12 by the evaporator air-sending fan 24 is cooled by passing through the evaporator 23. The cold air from the evaporator 23 is sent out from the air outlet 14. The refrigerant leaving the evaporator 23 returns to the compressor 31 and is compressed again.
In the heating operation of the air-conditioning unit 51, as shown in fig. 4, the high-temperature and high-pressure refrigerant compressed by the compressor 31 is sent to the condenser 25 via the four-way valve 32. In the condenser 25, the air sucked in from the second air inlet 13 by the condenser fan 33 is sent toward the condenser 25 to be cooled, and the refrigerant is liquefied. The air having passed through the condenser 25 is sent out as warm air from the air outlet 14 in a state including heat released by liquefaction of the refrigerant in the condenser 25.
The liquefied refrigerant is sent to the expansion valve 34, and is injected into the evaporator 23 from a minute nozzle hole of the expansion valve 34 to be vaporized at a time. The vaporized refrigerant takes heat from the periphery of the evaporator 23, and the evaporator 23 is cooled. The air taken in from the first air intake port 12 by the evaporator air-sending fan 24 is cooled by passing through the evaporator 23. The cold air from the evaporator 23 is discharged from the heat discharge port 15. The refrigerant leaving the evaporator 23 returns to the compressor 31 and is compressed again.
(advantages of air conditioner 1)
Since the air conditioner 1 of the present embodiment is provided with the waste water container 22 so as to be in contact with the battery 21, when the battery 21 generates heat due to discharge during operation of the air conditioner 1, the battery 21 can be cooled by the waste water 26 in the waste water container 22. That is, the air conditioner 1 can cool the battery with a simple and low-cost configuration without causing a reduction in the air conditioning function. This can prevent a decrease in performance due to a temperature increase of the battery 21 and prolong the operation time of the air conditioner 1.
[ embodiment 2 ]
Other embodiments of the present invention will be described below. For convenience of explanation, the same reference numerals are given to the components already described in the above embodiments and the components having the same functions, and the description thereof will not be repeated.
(constitution of air conditioner 2)
Fig. 5 is a schematic diagram showing the internal configuration of the air conditioner 2 according to the present embodiment. As shown in fig. 5, the air conditioner 2 includes a waste water pipe (waste water treatment unit) 41 instead of the waste water tank 22 of the air conditioner 1. The waste water pipe 41 has an upstream end connected to the waste water tray 27 and a downstream end provided with an on-off valve 42. The waste water pipe 41 is preferably made of a material having good thermal conductivity, for example, a material containing aluminum as a main component. The on-off valve 42 is opened and closed by, for example, manual operation. The other configurations of the air conditioner 2 are the same as those of the air conditioner 1 described above.
(positional relationship between the waste water pipe 41 and the battery 21)
The waste water pipe 41 is a pipe for discharging the waste water 26 generated in the evaporator 23 to the outside of the body. The waste water 26 generated in the evaporator 23 is received by the waste water tray 27, flows through the waste water pipe 41, and is discharged to the outside of the body by opening the open/close valve 42. The waste water pipe 41 is provided on the upper surface of the battery 21 so as to contact the battery 21. Therefore, the upper surface of the battery 21 is preferably gently inclined downward from the upstream side to the downstream side of the waste water pipe 41.
The position of the waste water pipe 41 is not limited to the upper surface of the battery 21, and may be disposed so as to contact the outer surface of the battery 21. For example, the waste water pipe 41 may be disposed around the battery 21 so as to contact the side surface of the battery 21. The above configuration is also the same in the air conditioner 3 described later.
(advantages of air conditioner 2)
Since the air conditioner 2 of the present embodiment is provided with the waste water pipe 41 so as to be in contact with the battery 21, when the battery 21 generates heat due to discharge during operation of the air conditioner 2, the battery 21 can be cooled by the waste water 26 flowing through the waste water pipe 41. That is, the air conditioner 1 can cool the battery with a simple and low-cost configuration without causing a reduction in the air conditioning function. This can prevent a decrease in performance due to a temperature increase of the battery 21 and prolong the operation time of the air conditioner 2. The configuration of the air conditioner 2 having the waste water pipe 41 as described above is suitable for a small-sized air conditioner not including the waste water tank 22.
(concrete constitution example of waste water pipe 41)
Fig. 6 is a perspective view showing a specific configuration example of the waste water pipe 41. As shown in fig. 6, the waste water pipe 41 may be provided in a state of meandering on the upper surface of the battery 21. In such a configuration, the contact area between the waste water pipe 41 and the battery 21 is increased, and the cooling function of the battery 21 by the waste water 26 flowing through the waste water pipe 41 can be improved.
[ embodiment 3 ]
Another embodiment of the present invention will be described below. For convenience of explanation, the same reference numerals are given to the components already described in the above embodiments and the components having the same functions, and the description thereof will not be repeated.
(constitution of air conditioner 3)
Fig. 7 is a schematic diagram showing the internal configuration of the air conditioner 3 according to the present embodiment. Fig. 8 is a front view of the heat sink 43 shown in fig. 7.
As shown in fig. 7, the air conditioner 3 includes a waste water pipe 41, similarly to the air conditioner 2, instead of the waste water tank 22 of the air conditioner 1. The air conditioner 3 further includes a heat sink 43.
The heat sink 43 is fixed to the upper surface of the battery 21. The fins 43 are preferably made of a material having good thermal conductivity, for example, a material containing aluminum as a main component, as in the waste water pipe 41. As shown in fig. 8, the heat sink 43 has a through hole 43c in the lower base 43a, and the waste water pipe 41 penetrates the through hole 43 c. The upper portion of the heat sink 43 is a fin portion 43b, and at least a part of the fin portion 43b is present in the air passage of the air between the evaporator 23 and the evaporator air-sending fan 24.
The evaporator air-sending fan 24 rotates during operation of the air conditioner 3, and a flow of air from the second air inlet 13 toward the air outlet 14, that is, a flow of air from the evaporator 23 toward the evaporator air-sending fan 24 is generated between the evaporator 23 and the evaporator air-sending fan 24. However, the heat radiation fins 43 are disposed at positions that do not significantly affect the original wind flow between the evaporator 23 and the evaporator air-sending fan 24. The other configurations of the air conditioner 3 are the same as those of the air conditioners 1 and 2 described above.
(advantages of air conditioner 3)
In the air conditioner 3 of the present embodiment, as in the case of the air conditioner 2, since the waste water pipe 41 is provided so as to be in contact with the battery 21, when the battery 21 generates heat due to discharge during operation of the air conditioner 2, the battery 21 can be cooled by the waste water 26 flowing through the waste water pipe 41. That is, the air conditioner 1 can cool the battery with a simple and low-cost configuration without causing a reduction in the air conditioning function. This can prevent a decrease in performance due to a temperature increase of the battery 21 and prolong the operation time of the air conditioner 2.
Since the heat sink 43 is fixed to the upper surface of the battery 21, at least a part of the fin 43b is present in the air passage of the air between the evaporator 23 and the evaporator air-sending fan 24, and the cooling of the battery 21 can be promoted by the air between the evaporator 23 and the evaporator air-sending fan 24. Also, the battery 21 can be cooled even when no wastewater flows through the wastewater pipe 41.
Further, since the waste water pipe 41 is provided so as to penetrate the heat radiating fins 43, that is, so as to pass through the inside of the heat radiating fins 34, the waste water 26 in the waste water pipe 41 can be cooled by the heat radiating fins 43. This can further improve the cooling function of the battery 21 by the waste water 26 in the waste water pipe 41.
The waste water pipe 41 is not limited to the structure penetrating the fins 43, and may be disposed independently of the fins 43.
(concrete constitution example of waste water pipe 41)
Fig. 9 is a perspective view showing a specific configuration example of the waste water pipe 41. As shown in fig. 9, the waste water pipe 41 is provided in a state of meandering on the upper surface of the battery 21 as in the case of fig. 6, and the cooling function of the battery 21 by the waste water 26 flowing through the waste water pipe 41 can be improved.
The heat sink 44 has a base 44a, a piece 44b, and a through hole 44c, as in the heat sink 43. The through-holes 44c of the heat sink 44 are in the longitudinal direction of the heat sink 44, unlike the heat sink 43. Therefore, the longitudinal direction of the fin 44 is parallel to the direction of the meandering waste water pipe 41. The other heat dissipation fins 44 are arranged in the same manner as the heat dissipation fins 43.
The advantage of having the fins 44 and the waste water pipe 41 penetrating the fins 44 is the same as in the case of the configuration shown in fig. 7.
[ embodiment 4 ]
Another embodiment of the present invention will be described below. For convenience of explanation, the same reference numerals are given to the components already described in the above embodiments and the components having the same functions, and the description thereof will not be repeated.
(construction of Fan control System 52)
Fig. 10 is a block diagram showing a configuration of a fan control system 52 included in the air-conditioning apparatus 4 according to the present embodiment. The air-conditioning apparatus 4 is configured such that the air-conditioning apparatus 3 is further provided with a fan control system 52.
As shown in fig. 10, fan control system 52 includes a temperature sensor 53 and a fan control unit 54. The temperature sensor 53 measures the temperature of the battery 21.
The fan control unit 54 is constituted by, for example, a microcomputer, and rotates the evaporator air-sending fan 24 when the temperature of the battery 21 detected by the temperature sensor 53 exceeds a predetermined threshold value. The predetermined threshold value is, for example, an upper limit value of an appropriate operating temperature range according to the type of the battery.
(operation of Fan control System 52 and advantages of air conditioner 4)
The battery 21 is charged by receiving a direct current (for example, 24V) from a power supply unit. The power supply unit may be an internal power supply unit included in the air conditioner 4, or may be an external power supply unit.
During charging, the temperature of the battery 21 rises, and the temperature tends to exceed the upper limit value (threshold value) of the appropriate operating temperature range. Therefore, the fan control unit 54 rotates the evaporator air-sending fan 24 at, for example, a low speed when the temperature of the battery 21 detected by the temperature sensor 53 exceeds a threshold value. This makes it possible to promote cooling of battery 21 by fins 43 and 44 by blowing air against fins 43 and 44. As a result, temperature rise during charging of the battery 21 is suppressed, and the battery 21 can be charged at high speed. Also, deterioration of the battery 21 due to a temperature rise during charging can be suppressed.
