As shown in FIG. 3, a DC jack 23 and an AC jack 24 are provided on the side portion 31 b of the outer frame body 31. A battery of the two-wheeled vehicle is connected to the DC jack 23, and DC power is supplied from the battery to the electronic circuit components constituting the cooling unit 6, the heat radiating fan 11, and the internal fan 12. When an AC power source is connected to the AC jack 24 and no battery is connected to the DC jack 23, the AC power is converted to DC power, and DC power is supplied to the electronic circuit components, the heat radiating fan 11, and the internal fan 12. Although the arrangement position of the electronic circuit component is not shown, the electronic circuit component is arranged in a space formed by the base 31 e and the attachment member 13 or in a cooling air passage located on the heat radiation side fin 10.

  As shown in FIG. 5, the electronic circuit component drives at least the thermoelectric element 8 and controls the current flowing in the thermoelectric element 8 and the heat dissipation fan 11, and the rotation speed of the heat dissipation fan 11. And a heat radiating fan driving means 102 for controlling the thermoelectric element driving means 101 and the heat radiating fan driving means 102 in response to a detection signal from the acceleration sensor 100.

  The acceleration sensor 100 is attached to the cooling air path forming member 15. The acceleration sensor 100 detects the acceleration of the motorcycle and controls the thermoelectric element driving means 101 and the heat radiating fan driving means 102 via the control means 103. When the speed of the two-wheeled vehicle increases and the acceleration increases, the air taken in from the intake portion 52a increases and the airflow flowing from the arrow A to C increases, so that the radiating fan 11 is stopped or the radiating fan 11 The heat radiating fan driving means 102 is controlled so that the driving state does not hinder the flow. As the air flow increases, the heat radiation by the heat radiation side fins 10 also increases, so that the current flowing through the thermoelectric element 8 can be reduced, and the thermoelectric element driving means 101 is controlled so as to decrease the current flowing through the thermoelectric element 8. As a result, power consumption by the power source 200 connected to the DC jack 23 or the AC jack 24 can be reduced.

  Also, if the motorcycle refrigerator continues to operate when the motorcycle has been stopped for a long time, if the battery is used as the power source 200, the battery power is used with insufficient power supplied to the battery, The battery and the refrigerator for the motorcycle may be disturbed. However, in the refrigerator for a motorcycle according to the first embodiment, the timer receives a detection signal indicating that the motorcycle is stopped from the acceleration sensor 100, and the thermoelectric element is connected via the control means 103 when the detection signal indicating the stop continues for a long time. The driving unit 101 stops the thermoelectric element 8, and the heat radiating fan driving unit 102 stops the heat radiating fan 11. As a result, excessive use of the battery can be prevented.

The two-wheeled refrigerator shown in Embodiment 1 configured as described above is attached to the rear loading platform of the two-wheeled vehicle as shown in FIG. At the time of attachment, it has a top valley region 3c lower than the upper surface of the front region 3a and the rear region 3b, and the length in the front-rear direction of the front region 3a is shorter than the length in the front-rear direction of the rear region 3b. Do not make a mistake.
Since it can be mounted on the carrier of the motorcycle without making a mistake in the front-rear direction, the intake portion 52a can be easily installed toward the front in the traveling direction of the motorcycle. In addition, as shown in FIG. 6, the front region 3 a and the top valley region 3 c are interposed between the driver's back and the intake portion 52 a, so that the intake portion 52 a is blocked by the driver's own back. There is no fear of getting lost. Therefore, the traveling wind is efficiently taken in from the intake portion 52a, and the heat radiation on the heat radiation side fin 10 can be sufficiently performed in the traveling state of the motorcycle. Further, the heat dissipation fan 11 can be stopped by the detection signal from the acceleration sensor 100, and the power consumption of the power source 200 can be reduced. Further, by stopping the radiating fan 11, the traveling wind from the intake portion 52 a is not hindered by the radiating fan 11 itself.

Since the cooling unit 6 is disposed in the upper unit 3, when the lid body 17 is opened and closed for putting food in and out of the storage section of the inner case 42, the temperature change in the storage section of the inner case 42 due to opening and closing of the lid body 17 is caused. Minimized.
When a thing containing much moisture such as ice or fish is accommodated in the accommodating portion of the inner case 42, the leaked moisture or the like is discharged out of the lower housing case 4 through the drain pipe 45. When the storage part of the inner case 42 is soiled by moisture remaining without being discharged and needs to be cleaned, the upper unit 3 can be removed from the lower housing case 4 and cleaning is easy.

Further, since the cooling unit 6 and the electronic circuit components are arranged in the upper unit 3, the water leaked when the water containing a lot of water is stored in the storage part of the inner case 42, and the water washing of the storage part of the inner case 42 There is no possibility that the cooling unit 6 and the electronic circuit components are damaged by the water from the cleaning.
Since the acceleration sensor 100 detects the traveling state of the two-wheeled vehicle and controls the heat dissipation fan 11 and the thermoelectric element 8, the heat radiation in the traveling state of the two-wheeled vehicle is efficiently used and the two-wheeled vehicle is stopped. The power supply to the heat dissipation fan 11 and the thermoelectric element 8 can be suppressed.
