Description

Technical Field

[0001] This utility model relates to a device capable of both cooling and heating, and more particularly to a cooling and heating compatible electric fireplace for RVs. Background Technology

[0002] A motorhome, combining the functions of a "house" and a "vehicle," is a type of mobile vehicle equipped with essential home amenities. These amenities include: bedding, stove, refrigerator, cabinets, sofa, dining table and chairs, water heater, air conditioner, television, heater, and other furniture and appliances. A motorhome integrates "clothing, food, shelter, and transportation," realizing a fashionable product that allows one to "live while traveling and travel while living."

[0003] The air conditioning in a typical RV usually uses a compressor as the power source for cooling, which is not only noisy but also expensive. The heating equipment in a typical RV is usually a diesel heater, although an electric fireplace can also be used. However, an electric fireplace usually uses heating wires in conjunction with a fan to achieve heating, so it cannot achieve cooling and its function is relatively limited.

[0004] Therefore, the applicant designed a holographic RV heater with hot and cold air functions by utilizing the principle that semiconductors can generate heat and cool. Utility Model Content

For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element, without departing from the scope of this disclosure.

[0032] As will be fully understood by those skilled in the art, the features of the different embodiments of this disclosure may be coupled or combined with each other in part or in whole, and may cooperate with each other and be technically driven in various ways. The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0033] Reference Figures 1 to 7 This utility model discloses a heating and cooling compatible electric fireplace for RVs, including a heating and cooling semiconductor module 1. The heating and cooling semiconductor module 1 in this application is an externally purchased component. Its principle is as follows: a P-type semiconductor and an N-type semiconductor are used, and two metal conductors are welded together to form an electrical couple. When direct current flows from the N-type semiconductor to the P-type semiconductor, one of the metal conductors absorbs heat; this end is called the cold end. Meanwhile, the other metal conductor releases heat; this end is called the hot end. If the current direction is reversed, the cold and hot ends will be interchanged.

[0034] As shown in the figure, it also includes an outer casing 2, a fan 3 and a fan 4 disposed within the outer casing 2, and a heat exchanger 5 and a heat exchanger 6 on the heating and cooling semiconductor module 1. The heat exchanger 5 and the heat exchanger 6 are generally made of copper or aluminum, which have good thermal conductivity. The outer casing 2 has a chamber 7 and a chamber 8. The chamber 7 has an air inlet 9 and an exhaust 10; the chamber 8 has an air inlet 11 and an exhaust 12. The heat exchanger 5 is located in the chamber 7, and the heat exchanger 6 is located in the chamber 8. The fan 3 allows the air entering through the air inlet 9 to be heated or cooled by the heat exchanger 5 and then blown out through the exhaust 10. The fan 4 allows the air entering through the air inlet 11 to be heated by the heat exchanger 6 and then discharged through the exhaust 12. With the above structure, when cooling is required, the heating and cooling semiconductor module 1 and the heat exchanger 6 can exchange heat and then be discharged through the exhaust 12. The side of the heat exchanger 5 that is in contact with the heat exchanger absorbs heat, causing the temperature of the heat exchanger 5 to drop. As a result, the air is cooled after passing through the heat exchanger 5 and is finally blown out through the exhaust port 10, thereby lowering the temperature inside the RV. Similarly, when heating is required, the side of the heating and cooling semiconductor module 1 that is in contact with the heat exchanger 5 releases heat, causing the temperature of the heat exchanger 5 to rise. As a result, the air is heated after passing through the heat exchanger 5 and is finally blown out through the exhaust port 10, thereby raising the temperature inside the RV. Of course, based on the principle of the heating and cooling semiconductor module 1, the second heat exchanger 6 will also produce a heating and cooling process opposite to that of the heat exchanger 5. This process is opposite to the user's needs. Moreover, in order to prevent the heating and cooling semiconductor module 1 from being locally overcooled or overheated, it is necessary to draw in air through the air inlet 11 to exchange heat with the second heat exchanger 6. The air after heat exchange is exhausted outside the RV through the exhaust port 12.

[0035] Of course, for ease of installation, the second exhaust port 12 is connected to an exhaust pipe 13 that communicates with the outside. The exhaust pipe 13 can easily extend out of the RV, so that the air after heat exchange can be discharged through the second exhaust port 12.

[0036] As shown in the figure, the compartment 7 includes a receiving compartment 14 and an air duct 15 communicating with the receiving compartment 14. The heat exchanger 5 is installed in the receiving compartment 14. The air inlet 9 is located on the wall of the receiving compartment 14. The air outlet of the air duct 15 is the exhaust port 10. The fan 3 is installed outside the receiving compartment 14 and communicates with the air inlet 9. The fan 3 of this application is an axial flow fan. The axial flow fan directly draws air from the outer shell 2, and then blows the air into the receiving compartment 14 through the air inlet 9 and heats or cools it through the heat exchanger 5. Then it blows the air out of the air outlet of the air duct 15 into the interior of the RV. Of course, the outer shell 2 is also provided with a through hole opposite to the exhaust port 10 to facilitate the air blowing out.

[0037] As shown in the figure, both ends of the second chamber 8 are equipped with the second fan 4. The exhaust pipe 13 is connected to one of the second fans 4. The fan is a common exhaust fan. Because the exhaust path is long, this application has installed exhaust fans at both ends of the second chamber 8. One exhaust fan draws the air in the outer shell 2 into the second chamber 8 and after heat exchange through the heat exchanger 6, the heat-exchanged air is discharged into the exhaust pipe 13 by the other exhaust fan.

[0038] As shown in the figure, the heat exchanger 5 includes a square frame with openings on both sides. Several V-shaped heat exchange plates are provided inside the square frame. One opening is connected to the fan 3, and the other opening is connected to the air duct 15. The above structure not only has good heat exchange effect, but is also compatible with axial flow fans. The heat exchanger 6 has grooves on its left and right sides and bottom surface. Several heat dissipation plates are provided in the grooves, and the heat dissipation plates are arranged along the length of the grooves. The heat exchanger 6 has a heat exchange hole in its center. Air passes through the gaps between the heat dissipation plates and the heat exchange hole to achieve large-area heat exchange.

[0039] As shown in the figure, it also includes an inner shell 16 fixed inside the outer shell 2. The accommodating chamber 14 and the second chamber 8 are composed of the inner shell 16. The inner shell 16 is made of iron plate bent and welded and is fixed inside the outer shell 2 by screws. For ease of manufacturing and assembly, the inner shell 16 includes a left half shell 17 and a right half shell 18. The left half shell 17 and the right half shell 18 are connected as one piece by screws.

[0040] As shown in the figure, the outer shell 2 is provided with a display compartment 19, which contains an electronic screen 20 and a decorative artificial material 21. The opening of the display compartment 19 is provided with transparent glass 22. Because this product can heat and cool, an externally purchased electronic screen 20 is used as a display to match the heating and cooling effects. When heating, it can display flames, and when cooling, it can display snowflakes, thus giving people a psychological suggestion and achieving a better matching effect. Of course, the decorative artificial material 21 can also be selected as needed.

Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
