Description

Technical Field

[0001] The present invention relates to the field of prefabricated buildings, and particularly to a prefabricated wall panel and a prefabricated building constructed therefrom. Background Art

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to a factory. Building components and fittings are processed and manufactured in the factory and transported to the construction site, where they are assembled and installed on-site through reliable connection methods. Prefabricated buildings mainly include precast prefabricated concrete structures, steel structures, and modern timber structures. Because of their standardized design, factory production, assembly construction, information management, and intelligent applications, they are representatives of modern industrial production methods.

[0003] Container houses are common prefabricated buildings and are often used in people's daily lives, bringing more convenient and comfortable living. Container houses of different sizes can be made according to the number of people. However, there are still many disadvantages regarding the living problems of container houses. In harsh environments, especially in winter and summer, it will be very cold and hot. Currently, the scope of use of container houses is mostly temporary living places for construction sites, or products provided by outdoor camping merchants for users to choose. Compared with traditional housing, the construction and use of container houses are simpler, and the investment cost is lower. Whether for self-living or commercial use, a lot of expenses can be saved. As a temporary living place for residents, a container house is a place responsible for the daily life of residents. The living experience of residents is closely related to the supporting facilities of the container house. Although some container houses have completed the supporting facilities such as kitchens, bathrooms, bedrooms, and toilets, in terms of the experience during use, especially the experience of taking a bath outdoors, users often have a poor feeling. Since the areas where container houses are used are mostly remote outdoors, the temperature is relatively lower than that in the central areas where people are more concentrated. When taking a bath in a container house, without a suitable supporting heating system, there will be no good bathing experience. Seriously, it may even lead to illness due to getting cold, affecting the normal life of residents.

[0004] The invention patent with the application number 201410633137.0 discloses a container. The container is provided with a foldable bracket and a photovoltaic power generation system. The foldable bracket is arranged on the top of the container, and the photovoltaic power generation system includes a photovoltaic cell module, which is arranged on the foldable bracket. The container of the present invention provides living and office electricity for the mobile house through the foldable photovoltaic power generation system installed on the container body, collects solar energy to the greatest extent in different latitudes, and shades and shelters the mobile house from rain through the foldable photovoltaic bracket with adjustable inclination. It is detachable by itself, facilitating assembly and transportation.

[0005] The above technology supports the daily life and office electricity consumption of container houses through mobile phone solar energy, improving the daily life experience, but does not address the problem of the shower experience for residents. A utility model patent with the application number 201820232566.0 discloses a container house bathroom, belonging to the technical field of bathroom equipment, including a container box body, with a bathroom door and a bathroom window provided on the side wall of the container box body. Inside the container box body, there are several groups of bathroom units and a shower device, and several solar water heaters are provided on the top. The bathroom unit includes a partition, a small bathroom door, a toilet seat, and a washing device.

[0006] By setting up a bathroom and a shower area inside the container house and separating them from the living area, the occupancy experience of container house residents will be greatly improved, meeting the daily needs of residents. Urgently needed to solve is the problem of improving the shower experience of residents. Summary of the Invention

[0007] The present invention provides a prefabricated building that can reduce the generation of water mist during user bathing.

[0008] To solve the above technical problems, the present application provides the following technical solutions:

[0009] A prefabricated building includes a battery assembly and a shower device. The battery assembly is used to supply power to the shower device, and also includes: a house body and a bathroom;

[0010] The bathroom is assembled inside the house body, and the battery assembly is fixed on the inner side of the top of the house body;

[0011] The shower device is installed in the bathroom. A drainage channel for drainage is provided below the wall of the bathroom, and a floor drain opening for drainage is opened on the bathroom floor. The floor drain opening is communicated with a branch pipe of the drainage channel; a heating cavity is opened inside the corner wall of the bathroom, and the heating cavity is communicated with the upper end of the drainage channel;

[0012] A heating part is arranged in the heating cavity. The heating part includes: a heating module. The battery assembly is used to supply power to the heating module. The heating module is fixed on the wall close to the bathroom side. The shower device includes a cold water pipe and an electric water heater. The water outlet end of the cold water pipe is communicated with the electric water heater. The front section of the cold water pipe is vertically fixed in the heating cavity, and the end of the cold water pipe close to the electric water heater is fixed in the heating module;

[0013] It further includes a support rod parallel to the front section of the cold water pipe. The upper end of the support rod is located in the heating chamber, and the lower end of the support rod is arranged in the drainage channel. It also includes a number of water scraping rings. The inner ring of the water scraping ring is slidably connected to the front section of the cold water pipe, and the outer ring of the water scraping ring is fixedly connected to the support rod. A sliding block is fixed at the lower end of the support rod, and the sliding block is slidably connected to the drainage channel. The sliding block is located below the connection between the floor drain opening and the branch pipe of the drainage channel. A fixed platform is fixedly arranged in the drainage channel below the sliding block. A first spring is arranged between the fixed platform and the sliding block. The upper end of the first spring is fixedly connected to the bottom of the sliding block, and the lower end of the first spring is fixedly connected to the fixed platform. It further includes a diversion channel for diverting the water from above the fixed platform to below the fixed platform. An inlet of the diversion channel is arranged between the initial position of the sliding block and the fixed platform, and an outlet of the diversion channel is arranged in the drainage channel below the fixed platform.

[0014] It further includes an exhaust fan. An air outlet communicating with the outside is opened above the heating chamber, and an air inlet communicating with the bathroom is opened below. The exhaust fan is installed at the air inlet of the heating chamber for sucking the water mist generated during bathing in the bathroom from below into the heating chamber.

[0015] It further includes a switch device for controlling the heating module to be powered on when the sliding block moves down to the limit position.

[0016] Basic principle of this solution: When taking a bath in winter, water flows from the floor drain into the branch pipe of the drainage channel, then flows to the drainage pipe and converges above the sliding table. When the sliding table is not lowered to the limit position, the sliding table blocks the diversion channel. As the bathing water continues to increase, the mass of the water converging above the sliding block increases. Under the action of gravity, the sliding block moves downward. When the sliding block moves downward to the limit position, the inlet of the diversion channel is exposed, and water flows from the inlet of the diversion channel to the outlet and is discharged into the drainage channel below. When the sliding block moves downward to the limit position, the switch device is triggered, and at this time, the heating module and the exhaust fan are started. As the bathing time increases, due to the large temperature difference between the water temperature and the room temperature, air atomization is caused, and a large amount of water mist is generated in the bathroom. The exhaust fan extracts the hot water mist from the bathroom to the heating cavity. Since one section of the cold water pipe of the electric water heater is arranged in the heating cavity, the hot water mist contacts the cold cold water pipe, and the water mist will condense into small water droplets and adhere to the cold water pipe. Moreover, since the air outlet faces the outside with a lower temperature, the hot water mist enters from the lower air inlet. Due to the chimney effect, the hot water mist will rise, so as to fully contact the cold water pipe. The water scraping ring is slidably connected to the cold water pipe, and the water scraping ring synchronously slides up and down with the sliding block through the support rod, so as to scrape off the water droplets condensed on the cold water pipe and drip into the drainage channel below the heating cavity, completing the preliminary removal of the water droplets on the cold water pipe in the heating cavity. After the heating module is powered on, it heats the bathroom and dries the heating cavity at the same time, preventing excessive moisture from remaining and causing corrosion and damage to the heating cavity and the cold water pipe, etc.

[0017] Beneficial effects of this solution: 1. When the sliding block moves downward to the limit position, the switch device is triggered, so that the exhaust fan and the heating module are powered on, completing automatic control. Since the power of the current water heater is insufficient in the early stage of startup and a part of cold water will be discharged, the mass of this part of cold water is matched with the mass required for the sliding block to move from the initial position to the limit position, so that when the water heater just outputs hot water, the heating module is triggered to start and heat the household taking a bath. The household can also make preparations during this time and can feel the heating of the heating module when starting to take a bath, improving the shower experience of the household.

[0018] 1. Since the water temperature difference is small when the water heater discharges cold water and no water mist will be generated, through the setting of the switch device, the exhaust fan is triggered to start only when hot water is discharged later, reducing the energy waste of the exhaust fan.

[0019] 2. During bathing, the water mist in the bathroom increases significantly. The water mist is continuously drawn into the heating chamber from the air inlet through the exhaust fan, reducing the residual water droplets on the bottom and walls of the bathroom. Since the heating module heats the walls of the bathroom, the temperature difference between the wall and the water mist is small, which will also reduce the residual water droplets on the wall, and then most of the water mist can enter the heating chamber through the exhaust fan, completing the removal of water mist in the bathroom, so that the occupants who are bathing have a wider field of vision than when there is no water mist removal, thereby improving the shower experience.

[0020] 3. The water mist gathered in the heating chamber condenses on the cold water pipe. While condensing, the heat it carries also remains on the cold water pipe. This part of heat can preheat the cold water in the cold water pipe, completing the recovery and utilization of waste heat and saving energy.

[0021] 4. The part of the cold water pipe close to the water heater is set in the heating module. The heating module can preheat the cold water pipe while heating the bathroom wall.

[0022] 5. As the water flow stops temporarily during the bathing process (for example, when turning off the water and applying shampoo) or when the bathing is finished, the gravity applied on the top of the sliding block decreases. Under the reset of the first spring, the sliding block moves upward, driving the guide rod to move upward, so that the wiper ring moves up and down, scraping off the water droplets condensed on the cold water pipe and dropping them into the drainage channel below. The residual heat of the heating module after stopping will dry the heating chamber and reduce the residual moisture in the heating chamber.

[0023] Furthermore, it also includes a solar panel, which is fixed to the upper end of the house body. The battery assembly is used to store energy collected from the solar panel and output a rated voltage.

[0024] Beneficial effects: Solar panels can continuously provide electricity for container houses, improving the living experience of residents and ensuring their daily needs.

[0025] Furthermore, a second spring is provided between the upper end of the support rod and the wall above the bathroom, one end of the second spring is fixedly connected to the upper end of the support rod, and the other end of the second spring is fixedly connected to the wall above the bathroom.

[0026] Beneficial effect: Used to pull the guide rod upward to scrape off water drops on the cold water pipe at the end of bathing.

[0027] Furthermore, a guide rod is protruding and fixed on the lower end of the sliding block, and a limiting groove is fixedly provided on the fixed platform, and the guide rod is slidably connected inside the limiting groove.

[0028] Beneficial effect: the moving direction of the sliding block is made constant, and the sliding block is prevented from being misplaced during the movement.

[0029] Further, the switch device is a push switch, and the push switch is arranged at the bottom of the limit groove. When the sliding block moves down to the limit position, the guide rod abuts against the push switch and triggers the heating module to be powered on.

[0030] Further, a plurality of groups of the limit grooves are symmetrically arranged.

[0031] Further, a retaining net is fixed at the air inlet.

[0032] Further, a support plate is fixedly arranged near the air inlet of the heating cavity. A plurality of air-permeable holes for water mist to pass through are formed in the support plate, and the exhaust fan is installed on the support plate with its fan surface tilted upward towards the bathroom.

[0033] Further, a heat insulation layer is arranged in the wall body of the house body.

[0034] An assembled wall panel, the wall panel is integrally molded from a PP modified material and a thermoplastic material with long glass fibers, and the house body is assembled from the wall panels.

[0035] Beneficial effects: The new composite material formwork can improve the construction quality of concrete in housing construction projects, reduce project costs, shorten the construction period, and enhance on-site safety and civilization. Description of the Drawings
