Abstract

This invention is an insulated bag which is capable of heating or cooling drinks and food. In the bag fits drinks box and food box, to the outside of the boxes attached heating film or PTC plate and semi-conductor refrigerating plate. The boxes are wrapped with insulating material. To the top inside cover of the food box fixes a refrigerating fan for fast refrigeration. The power is provided by battery or outside input. The bag is outfitted with battery shortage protection unit, short circuit protection unit and over heat protection unit. A temperature controller controls heating or refrigerating to the preset temperature. When short of battery or the temperature reaches the preset one, the bag sounds correspondingly. A metal (or plastic / nylon) unloadable rack to the outside of the bag and designed according to human body back is capable of heat dissipation in hot weather.

Description

Technical field:

[0001] The present invention is a kind of electric heating film (or PTC ceramic heating sheet) and semiconductor cooling sheet that can use the energy in the battery or connect the DC power supply from the outside to generate heat and cold in backpacks, satchels, and handbags. On the outer wall of the water box (water cup) and the food box, there is a multi-purpose heating and cooling insulation bag for heating or cooling water (beverage) and food. It can control the temperature of the heated and cooled water and food. Its circuit has short-circuit protection. Over-temperature protection, battery under-voltage (over-discharge) protection, can cut off the heating or cooling circuit power supply, and protect the safety of the battery pack and the entire circuit (including electric heating film and semiconductor cooling sheet). It can also use language (or music) to remind the user when the battery is under-voltage (over-discharged) or the heating and cooling tem...

Examples

Embodiment approach 1

[0007] 1. Inclusion structure:

[0008] According to Fig. 1 in knapsack, satchel, handbag (1a), the top of bag body has zip lock (1b), and the top in its bag is equipped with the water box (3) that has handle and cover (4) and food box ( 2) with the cover (5), the water discharge valve (20), a refrigerating cycle DC 12V fan (6) is adorned in the inside of the food box cover. Its outer wall of water box (3) and food box (2) is pasted with electric heating film (or PTC heating sheet) (7a) and (7b) that overtemperature protector (8a) and (8b) are connected in series on the positive pole line of the power supply, It has overtemperature protector (preventing semiconductor refrigeration sheet from overheating and burning) (10c) and (10d) semiconductor refrigeration sheet (10a) and (10b) at the positive line of the power supply, and the thermosensitive sensor probe (26 ) and (27). In the side of the non-human body in the bag, there are cooling fans (18), air ducts (19a), radiators ...

Embodiment approach 2

[0022] 1. Inclusion structure:

[0023] (1), the first inclusion structure:

[0024]In Fig. 1c: by hot water box (23a) and hot water box cover (28a), cold water box (23b) and cold water box cover (28b) replace the water box (3) and water box cover (4) of Fig. 1b. Replace the water discharge joint (20) of Fig. 1b by the hot water joint (32a), the cold water joint (32b), replace the valve (11a) with the garden arc valve (24), add the bottom box (25), and do the position Adjustment. Available hot food box cover (5a) and hot food box (2a) and cold food box cover (5b) and cold food box (2b) of Fig. 1h, replace food box cover (5) and food box (2) in Fig. 1, electric heating Film [or PTC heating sheet] (7a), (7b) and semiconductor refrigeration sheet (10a), (10b) and its overtemperature protector (8a) (8b) and (10c), (10d) and temperature sensor (26a ), (26b) and (27a), (27b) are attached to the outer walls of the water box and food box as shown in Figure 1c and Figure 1h, and two...

Embodiment approach 3

[0041] 1. Inclusion structure:

[0042] By the water cup (29) water cup cover (30) of Fig. 1d, replace the water box (3) of Fig. 1b and the water box cover (4) and the water discharge joint door (20), and cancel valve (11a), also can not replace, Food box (2) remains unchanged. Cancel the over-temperature protectors (10c) and (10d) of the semiconductor refrigeration sheet (10a) and (10b) of the water box and the food box and the semiconductor refrigeration sheet thereof, fan (18) and air duct (19a) and radiator (19b) And (19c) air inlet (19d) and air port cover (19e), air outlet (19f) and (19g) and air port cover (19h) and (19i), diode D3, D4, food box refrigeration circulation fan (6).
