Description

Technical Field

[0001] This utility model relates to the field of prefabricated house technology, and in particular to a prefabricated house that is easy to ventilate. Background Technology

[0002] Prefabricated houses are mainly composed of light steel structures, walls, roofs, doors and windows, etc. They are usually used for temporary or semi-permanent places, such as construction sites, field work sites, emergency shelters, offices and dormitories.

[0003] Existing prefabricated housing technologies, such as the patent disclosed in CN215490141U, disclose a prefabricated house that facilitates ventilation. While this prefabricated house overcomes the problems of poor ventilation in existing prefabricated houses, it cannot meet the requirement of "cool outside, warm inside; warm outside, cool inside." For example, in multi-person dormitories or hospital wards, when the outdoor temperature is below zero degrees Celsius, a certain amount of ventilation is still needed to prevent carbon dioxide accumulation. However, if the prefabricated house of this patent is used, cold air will enter the room, causing the indoor temperature to drop and affecting comfort. Furthermore, this patented prefabricated house does not achieve cooling and insulation effects. Therefore, this utility model proposes a prefabricated house that facilitates ventilation, solving at least one of the aforementioned technical problems. Utility Model Content

[0004] In order to overcome at least one of the technical problems mentioned in the background art, the present invention provides a prefabricated house that is easy to ventilate.

[0005] The technical solution is as follows: A prefabricated house with convenient ventilation includes a prefabricated house body. A partition is fixedly connected inside the prefabricated house body, dividing the prefabricated house body into a heat exchange chamber for containing water and a living room for normal use. A water level sensor and a temperature sensor are installed in the heat exchange chamber. A temperature controller is installed on the side wall of the prefabricated house body. The output end of the temperature controller is connected to the heat exchange chamber through a water inlet pipe, and the input end of the temperature controller is connected to the heat exchange chamber through a water outlet pipe. At least two ventilation components are installed on the living room. Each ventilation component includes a frame installed on the living room. Louvers, a heat exchanger, and an exhaust fan are sequentially installed in the frame from the outside to the inside of the prefabricated house body. One end of the heat exchanger is connected to the heat exchange chamber through a water pump installed on the bottom of the partition, and the other end is connected to the heat exchange chamber through a pipe and a one-way valve. The exhaust fan is installed in the frame through a rotating assembly.

[0006] Furthermore, the ventilation assembly also includes a baffle plate, and a baffle plate is also installed between the exhaust fan and the heat exchanger.

[0007] Furthermore, the ventilation assembly also includes a dustproof plate, with dustproof plates installed between the louvers and the heat exchanger, and on the frame located inside the main body of the prefabricated house.

[0008] Furthermore, the rotating assembly includes an arc plate and a drive motor. The arc plates are symmetrically rotatably connected within the frame. The exhaust fan is mounted on the arc plate. The drive motor is mounted on the outer wall of the frame. The output shaft of the drive motor is connected to the rotating shaft of one of the arc plates.

[0009] Furthermore, the partition plate is evenly distributed with through grooves, and an installation box is installed in the through groove. The installation box is hollow and filled with phase change material. Half of the installation box is located in the heat exchange chamber, and the other half is located in the living room.

[0010] Furthermore, a sealing ring is provided between the partition and the mounting box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model is equipped with ventilation components and other parts. When the exhaust fan is turned on, air is blown from the outside of the prefabricated house to the inside of the prefabricated house. When the water pump is turned on, the water pump draws water from the heat exchange chamber and delivers it to the heat exchanger. The heat exchanger exchanges heat with the air entering the prefabricated house, thereby regulating the temperature of the air entering the prefabricated house. This allows the ventilation to meet the requirement of "cold outside and hot inside, hot outside and cold inside", thus maintaining a certain amount of ventilation in winter and not being affected by the cold outside.

[0013] 2. This utility model includes components such as a temperature controller, a partition, and a mounting box. In summer, the temperature controller cools the water in the heat exchange chamber to form cold water, while the phase change material absorbs heat from the living room, thereby lowering the temperature of the living room. In winter, the temperature controller heats the water in the heat exchange chamber to form hot water, while the phase change material absorbs heat from the water in the heat exchange chamber and stores the heat in the phase change material. At the same time, the heat absorbed by the phase change material is released into the living room, causing the temperature in the living room to rise, thus achieving a good heating effect in the living room.

Detailed Implementation

[0020] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0021] A type of prefabricated house that is easy to ventilate, such as Figures 1-5As shown, the structure includes a prefabricated house main body 101. A partition 103 is sealed and fixedly connected inside the prefabricated house main body 101, dividing it into a heat exchange chamber 1011 for containing water and a living room 1012 for normal use. A temperature controller 102 is installed on the side wall of the prefabricated house main body 101. The output of the temperature controller 102 is connected to the heat exchange chamber 1011 via an inlet pipe 104, and the input of the temperature controller 102 is connected to the heat exchange chamber 1011 via an outlet pipe 105. A water level sensor and a temperature sensor (not shown in the figure) are installed inside the heat exchange chamber 1011. The water level sensor... Sensors and temperature sensors can accurately determine the water level and temperature inside the heat exchange chamber 1011. Two ventilation components are installed on the living room 1012. Evenly distributed channels are present on the partition 103, and mounting boxes 401 are installed within these channels. The mounting boxes 401 are made of copper, which has excellent thermal conductivity. The mounting boxes 401 are hollow and filled with a phase change material, specifically paraffin wax. Before use, the paraffin wax is heated to its phase change temperature, turning it into a liquid. The molten paraffin wax is then poured into the mounting boxes 401 and allowed to cool naturally. This results in a phase change material capable of storing temperature. During installation, the mounting boxes... Half of 401 is located in the heat exchange chamber 1011, and the other half is located in the living room 1012. A sealing ring 402 is provided between the partition 103 and the mounting box 401. Specifically, the ventilation assembly includes a frame 201 installed on the living room 1012. Inside the frame 201, from the outside to the inside of the main body of the prefabricated house 101, louvers 202, a heat exchanger 203, and an exhaust fan 204 are installed sequentially. The louvers 202 can be used to adjust the air intake and exhaust volume. One end of the heat exchanger 203 is connected to the heat exchange chamber 1011 through a water pump 207 installed on the bottom surface of the partition 103, and the other end is connected to the heat exchange chamber 1011 through a pipe and a one-way valve. The ventilation system includes a fan 204 installed inside the frame 201 via a rotating assembly. The ventilation system also includes a baffle 205, which is installed between the fan 204 and the heat exchanger 203. The baffle 205 is a highly efficient adsorbent, such as activated carbon, which can adsorb water molecules in the air to achieve dehumidification and prevent humid air from entering the living room 1012. The ventilation system also includes a dustproof plate 206, which is installed between the louvers 202 and the heat exchanger 203 and inside the frame 201 of the prefabricated house. The dustproof plate 206 is specifically a filter screen used to filter dust and other solid impurities.

[0022] Specifically, the rotating assembly includes an arc plate 301 and a drive motor 302. The arc plate 301 is symmetrically rotatably connected inside the frame 201. The exhaust fan 204 is mounted on the arc plate 301. The drive motor 302 is mounted on the outer wall of the frame 201. The output shaft of the drive motor 302 is connected to the rotating shaft of one of the arc plates 301. Initially, the fan blades of the exhaust fan 204 face inward towards the main body 101 of the prefabricated house, so that air can initially flow from the outside to the inside of the main body 101 of the prefabricated house.

[0023] Therefore, in use, a heat exchange chamber 1011 is formed on the upper part of the main body 101 of the prefabricated house via partition 103. The heat exchange chamber 1011 is filled with water, and the water temperature in the heat exchange chamber 1011 can be controlled by temperature controller 102. This allows the water in the heat exchange chamber 1011 to be heated to hot water or cooled to cold water. For example, in summer, the water in the heat exchange chamber 1011 can be cooled to cold water by temperature controller 102. The phase change material absorbs heat from the living room 1012 and stores the heat in the phase change material, thereby lowering the temperature of the living room 1012. The heat absorbed by the phase change material is then released into the water in the heat exchange chamber 1011, causing the water in the heat exchange chamber 1011 to heat up. When the water temperature is high enough, the water in the heat exchange chamber 1011 flows out through the water outlet pipe 10. 5. The water is sent back to the temperature controller 102 for cooling. After cooling, the water flows into the heat exchange chamber 1011 through the inlet pipe 104. This allows the living room 1012 to achieve good cooling. The use of phase change material can reduce temperature fluctuations in the living room 1012 and maintain a comfortable temperature. In winter, the temperature controller 102 heats the water in the heat exchange chamber 1011 to hot water. The phase change material absorbs the heat from the water in the heat exchange chamber 1011 and stores the heat in the phase change material, thereby lowering the water temperature in the hot chamber 1011. The heat absorbed by the phase change material is then released into the living room 1012, raising the temperature in the living room 1012 and thus achieving a good heating effect in the living room 1012.

[0024] Simultaneously, the exhaust fan 204 is started, causing its blades to rotate and air to blow from the outside of the prefabricated house body 101 into its interior. The water pump 207 is also started, drawing water from the heat exchange chamber 1011 and delivering it to the heat exchanger 203. The heat exchanger 203 exchanges heat with the air entering the prefabricated house body 101, thereby regulating the temperature of the air entering the prefabricated house body 101. For example, in summer, the water pump 207 delivers cold water from the heat exchange chamber 1011. The cold water enters the heat exchanger 203, where it absorbs heat and cools the air entering the main body 101 of the prefabricated house. In winter, the water pump 207 inputs hot water from the heat exchange chamber 1011 into the heat exchanger 203, where it releases heat and heats the air entering the main body 101 of the prefabricated house. This allows for ventilation to achieve the desired effect of "cold outside, hot inside, and hot outside, cold inside," thus maintaining a certain amount of ventilation in winter and preventing ventilation from being affected by the cold outside.

[0025] Because there are two ventilation components, when ventilation is needed, one of the exhaust fans 204 can be rotated to start the drive motor 302. The output shaft of the drive motor 302 then drives the arc plate 301 to rotate 180 degrees, which in turn rotates the exhaust fan 204 180 degrees. Then, both exhaust fans 204 are started simultaneously. One exhaust fan 204 delivers air from the outside of the prefabricated house body 101 to the inside of the prefabricated house body 101, while the other exhaust fan 204 delivers air from the inside of the prefabricated house body 101 to the outside of the prefabricated house body 101. In this way, the ventilation operation can be completed.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
