  However, in the above-described heat retention mat for piglets, the electric heater 2 is not laid on the entire lower surface of the surface cover 3, and the constant width portion of the outer peripheral portion is directly below the mat body 1 on the lower side of the surface cover 3. It has become. Therefore, the surface temperature of the portion of the surface cover 3 where the electric heater 2 is not laid is lower than that of the portion where the electric heater 2 inside is laid. As a result, piglets who prefer a warm place will feel uncomfortable in the low temperature part when getting on and off the heat-insulating mat, and will dislike riding the heat-insulating mat even though the center part of the heat-insulating mat is warm. was there. As a result, the frequency of use of the heat-insulating mat is reduced, and the growth may be adversely affected.

  Moreover, since the above-mentioned heat retention mat for piglets has a structure in which the upper surface of the electric heater 2 is covered with the surface cover 3 made of vinyl chloride, the surface cover 3 is formed by rubbing the surface cover 3 with claws. The nail touches the exposed electric heater 2 directly and the piglet may get an electric shock. As a result, there was a problem that the piglet that had received an electric shock learned to get an electric shock by using the heat-insulating mat and could not get on the heat-insulating mat again. In addition, the workers involved in raising piglets accidentally get an electric shock by touching the electric heater 2 by accidentally damaging the surface cover 3 of the heat-insulating mat with sharp nails, cutters, etc. There was also a problem that occurred. Therefore, the present invention proposes a heat retention mat for small animals such as piglets that eliminates the use of the low-temperature part of the outer periphery and is not repelled, and also proposes a heat retention mat for small animals such as piglets that can prevent electric shock accidents. Aimed to do.

  In order to solve the above problems, the present invention has a resin main body, a planar electric heater that is laminated on the upper surface of the main body and is smaller than the main body, and an uneven surface for preventing slippage on the outer surface. A heat retention mat for small animals such as piglets, which is formed and includes a top surface of the electric heater and a resin surface cover bonded to the outer periphery of the upper surface of the main body and the outer peripheral side surface of the main body. An aluminum sheet is laid on the entire surface. In the heat retention mat for small animals such as piglets, a power cord for supplying power to the electric heater and a grounded three-pole power plug, one end connected to the aluminum sheet and the other end connected to the ground 3 And a ground wire connected to a plug blade for the ground electrode of the pole power plug. Furthermore, a temperature sensor embedded in the main body for detecting the mat temperature, and a controller for controlling a current supplied to the electric heater based on the temperature detected by the temperature sensor.

According to the present invention described above, since the aluminum sheet is laid on the entire lower surface of the front cover, the heat generated by the electric heater is transmitted to the outer periphery of the front cover without the electric heater through the aluminum sheet having good heat conductivity. Thus, the entire surface of the front cover is kept at a predetermined temperature. As a result, it is solved that small animals such as piglets avoid the heat retention mat.
In addition, the grounded aluminum sheet is laid on the upper side of the electric heater, so that the electric heater is protected against external force, and even when the electric heater is exposed, the electric heater and the aluminum sheet are short-circuited. Electric shock accidents are prevented.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an enlarged cross-sectional view showing a part of a heat insulating mat according to the present invention. As shown in the drawing, an aluminum sheet 10 is bonded to the back surface of a surface cover 3 made of soft vinyl chloride having an uneven surface on the top surface. The aluminum sheet 10 is preferably a composite material in which an aluminum foil and a polyester film are bonded to achieve smoothness and heat resistance. In addition, an electric heater 2 made of a carbon wire surface heating element that is slightly smaller than the entire mat is disposed below the aluminum sheet 10, and a thermostat is placed on the center line in the width direction of the mat on the lower surface of the electric heater 2. 4, 5 and the temperature sensor 6 are embedded in the mat body 1 made of a vinyl chloride resin. These thermostats 4 and 5 and the temperature sensor 6 are connected to a controller.

  The aluminum sheet 10 is laminated between the electric heater 2 and the front cover 3 and is extended over the entire back surface of the front cover 3 so that the electric heater is interposed through the aluminum sheet 10 having good thermal conductivity. The front cover 3 positioned outside the mat body 1 and positioned on the outer peripheral edge of the mat body 1 is also heated. This is because, in the conventional heat insulating mat as shown in FIG. 6, the outer peripheral edge of the mat body is cold, but the outer peripheral edge of the mat body is heated substantially uniformly. Avoiding the low temperature part of the mat is eliminated.

  FIG. 2 is a circuit diagram showing an electrical configuration of the heat insulating mat of FIG. An electric heater 2, thermostats 4, 5, a temperature sensor 6 and an aluminum sheet 10 are disposed in the mat body 1, and these are connected to a controller 8 by a cord 15. A three-core cord is connected to the primary side of the controller 8 and the other end is connected to a grounded three-pole power plug 11. A grounding wire 12 connected to the aluminum sheet 10 is connected to the plug electrode blade for the grounding electrode of the three-pole power plug 11 via the controller 8. The three-pole power plug 11 is inserted into a grounded three-pole power outlet (not shown) and supplied with power when the heat insulating mat is used.

  The electric heater 2 is made of a carbon wire surface heating element and uses about 180 W. The thermostats 4 and 5 are provided for safety in the event that the controller 8 fails, and those with an operating temperature of 55 ° C. are used. The temperature sensor 6 uses a thermistor or the like. Reference numeral 7 denotes a set temperature input means comprising a dial type variable resistor or the like. When this mat is used for raising piglets, a temperature corresponding to the age of the piglets is set manually. The controller 8 compares the set temperature input from the set temperature input means 7 with the mat temperature detected by the temperature sensor 6 and controls the electric heater 2 on / off.

  That is, the controller 8 supplies AC100V to the electric heater 2 if the mat temperature is lower than the set temperature, and stops supplying AC100V to the electric heater 2 if the mat temperature is higher than the set temperature. In addition, since the carbon wire surface heating element is used as the electric heater 2, the leakage current when a part of the electric heater 2 is damaged becomes small. Therefore, the influence on piglets and the like is insignificant, and safety can be obtained as compared with other series electrode type and planar type electric heaters. Further, in the present invention, as described above, the controller 8 can change the set temperature so that when the mat is used for raising a piglet, the breeder, according to the age of the piglet, It is possible to finely adjust the set temperature.

  Further, the aluminum sheet 10 is disposed in close contact with the upper surface of the electric heater 2, so that the electric heater 2 is protected against external force, and the surface cover 3 is damaged by claws such as piglets. Even when the aluminum sheet 10 and the electric heater 2 are damaged, or when the electric heater 2 is accidentally damaged by a nail or a blade when the insulation mat is cleaned, the leakage current from the electric heater 2 is By flowing to the ground wire 12 through the aluminum sheet 10, an electric shock accident can be prevented. If a current leaks from the electric heater 2 to the aluminum sheet 10, the earth leakage breaker is activated and the power supply is shut off.

  FIG. 3 is an explanatory view showing a method for manufacturing a heat retention mat for piglets according to the present invention. In order to manufacture a heat retention mat for piglets, first, as shown in FIG. 1 (a), a surface cover 3 made of a soft vinyl chloride sheet larger than the finished mat is placed with the concavo-convex surface downward, that is, downward, and an adhesive on the back surface. The aluminum sheet 10 and the electric heater 2 made of a carbon wire surface heating element are stacked and bonded together. Next, as shown in FIG. 2 (b), the surface cover 3 to which the aluminum sheet 10 and the electric heater 2 are bonded is placed in the mold 9 while facing downward, and although not shown here, the thermostats 4 and 5, The sensors 6 and their wiring cords are arranged on the electric heater 2.

  Next, as shown in FIG. 3C, the regenerated PVC 17 that is softened by heating and softening is pressed down to a predetermined thickness on the entire inner surface of the mold 9. Next, as shown in FIG. 4D, after the compressed PVC is cooled and hardened, the ends of the surface cover 3 and the aluminum sheet 10 taken out from the mold 9 and protruding to the periphery are cut and removed to remove the mat body. To complete. Next, the controller 8, the three-pole power plug 11, etc. are attached to complete the whole. As described above, in the present invention, the aluminum sheet 10 and the electric heater 2 are arranged so as to overlap the inside of the surface cover 3 made of a vinyl chloride sheet, and the outer side thereof is further covered with the regenerated vinyl chloride 17. The entire structure excluding the electric heater 2 is made of polyvinyl chloride, which facilitates production and improves the durability in a structurally stable manner. In the present invention, in particular, the cost can be reduced by using recycled PVC. Of course, it is also possible to manufacture using a new PVC which is not a recycled PVC.

  The present invention can be used for breeding small animals such as dogs and cats in addition to breeding piglets.
