Description

Technical Field

[0001] This application relates to the field of bathroom technology, and in particular to a hot and cold bathtub. Background Technology

[0002] As people's living standards improve and the home furnishing industry develops rapidly, people's demand for home furnishing products is increasing. More and more young people want to install bathtubs when renovating their bathrooms, which meets people's current demand for high-quality home furnishing products.

[0003] Traditional bathtubs are simply tubs for holding water; as long as water can be added, they meet people's bathing needs. With the development of the bathroom industry, people have endowed bathtubs with more functions, such as automatic water supply and drainage, automatic heating, and automatic water level detection—features that are now quite common. Furthermore, with the rapid rise of the smart home industry, people have increasingly higher demands for the diverse functions of home products. This necessitates that manufacturers design appropriate hardware for bathtubs to meet automation requirements.

[0004] In addition, research shows that taking cold showers has many health benefits and can play a certain role in health care. However, a small group of people are accustomed to taking cold showers, which means that the same bathtub cannot meet the preferences of different users in the same family, and therefore cannot meet the needs of different users.

[0005] Some related technologies include temperature-adjustable massage bathtubs that use compressors to both cool and heat the water in the tub, meeting the needs of different users to some extent. However, these bathtubs, which use compressors to both cool and heat a single tub, are not only expensive to install and maintain, but also difficult to repair. Furthermore, current bathtubs typically only have one tub, preventing multiple users from bathing simultaneously; or, if users want to bathe in water of different temperatures, a large water change is required, which takes a considerable amount of time, resulting in insufficient time and affecting the bathing experience.

Pipe 212 and the second outlet pipe 222 are connected, and the hot water return pipe 364 is connected to the first outlet pipe 212 and the second outlet pipe 222 respectively; the control component includes a controller 410, a first solenoid valve 420 and a second solenoid valve 430. The controller 410 is disposed in the housing 100 and is connected to the cooling and heating component 300. The inlet end of the first solenoid valve 420 is connected to the first outlet branch pipe 362 or the third outlet branch pipe 352, and the outlet end of the first solenoid valve 420 is connected to the first inlet pipe 211. The inlet end of the second solenoid valve 430 is connected to the second outlet branch pipe or the fourth outlet branch pipe 353, and the outlet end of the second solenoid valve 430 is connected to the second inlet pipe 221. The first solenoid valve 420 and the second solenoid valve 430 are connected to the controller 410 respectively.

[0028] When the first bath 210 and the second bath 220 are simultaneously hot bathing, the controller 410 controls the inlet end of the first solenoid valve 420 to connect with the first outlet branch pipe 362 and the inlet end of the second solenoid valve 430 to connect with the second outlet branch pipe. At this time, the cooling and heating component 300 outputs hot water through the first outlet branch pipe 362 and the second outlet branch pipe, and sends it into the first bath 210 and the second bath 220 through the first inlet pipe 211 and the second inlet pipe 221 respectively. At the same time, the first outlet pipe 212 and the second outlet pipe 222 output the water in the first bath 210 and the second bath 220 respectively, and return it to the cooling and heating component 300 through the hot water return pipe 364.

[0029] When the first bath 210 and the second bath 220 are simultaneously in a cold bath, the controller 410 controls the inlet of the first solenoid valve 420 to connect with the third outlet branch pipe 352 and the inlet of the second solenoid valve 430 to connect with the fourth outlet branch pipe 353.

At this time, the cooling and heating component 300 outputs hot water through the first outlet branch pipe 362 and cold water through the fourth outlet branch pipe 353 respectively. The hot water is sent into the first bath 210 through the first inlet pipe 211 and the cold water is sent into the second bath 220 through the second inlet pipe 221. At the same time, the first outlet pipe 212 and the second outlet pipe 222 output the water in the first bath 210 and the second bath 220 respectively, and return it to the cooling and heating component 300 through the hot water return pipe 364 and the cold water return pipe respectively.

[0031] When the first bath 210 and the second bath 220 are in cold and hot bath respectively, the controller 410 controls the inlet of the first solenoid valve 420 to connect with the third outlet branch pipe 352 and the inlet of the second solenoid valve 430 to connect with the second outlet branch pipe. At this time, the cooling and heating component 300 outputs cold water through the third outlet branch pipe 352 and hot water through the second outlet branch pipe. The cold water is sent into the first bath 210 through the first inlet pipe 211 and the hot water is sent into the second bath 220 through the second inlet pipe 221. At the same time, the first outlet pipe 212 and the second outlet pipe 222 output the water in the first bath 210 and the second bath 220 respectively, and return it to the cooling and heating component 300 through the hot water return pipe 364 and the cold water return pipe respectively.

[0032] The hot and cold bathtubs described in this application not only enable multiple users to take a hot bath at the same time, multiple users to take a cold bath at the same time, or multiple users to take a cold bath or a hot bath separately, but also enable the same user to quickly switch between hot and cold baths without waiting for a long time to adjust the temperature, thus improving the bathing experience for the user.

Further, an expansion valve 370 is provided at the first end of the dryer filter 330, and the condenser 320 and the first heat exchanger 350 are respectively connected to the expansion valve 370. By adopting the above structure, hot or cold water can be output for hot or cold baths, thereby meeting the user's needs and improving the user's bathing experience. It is conceivable that both the hot water return pipe 364 and the cold water return pipe 354 are equipped with water pumps 380 to facilitate the discharge of hot and cold water, resulting in a simple structure and easy operation.

[0034] In some embodiments of this application, the cooling and heating assembly 300 further includes a sterilizer 390, which is respectively installed in the cold water outlet pipe 351 and the hot water outlet pipe 361.

Furthermore, the housing 100 is provided with steps 110, and the first bathtub 210 and the second bathtub 220 are provided with benches 240. By providing steps 110, when the first bathtub 210 and the second bathtub 220 are at a relatively high height, the user can enter the first bathtub 210 and the second bathtub 220 via the steps 110, improving the user experience; by providing benches 240, the user can sit on the benches 240 while bathing, improving the user's bathing experience. It is conceivable that the first bath 210 and the second bath 220 are respectively equipped with temperature sensors, which are connected to the controller 410 and the cooling and heating components 300, so as to monitor the temperature of the first bath 210 and the second bath 220 in real time and keep the first bath 210 and the second bath 220 in a constant temperature state, thereby improving the user's bathing experience.

[0036] In some embodiments of this application, the controller 410 is provided with a control panel, which is disposed on the surface of the housing 100. The control panel is a touchscreen. Users can turn the hot and cold bathtubs on or off via the control panel, and can also preset the temperatures of the first bathtub 210 and the second bathtub 220. Furthermore, the controller 410 is provided with one or more modules such as a Bluetooth module, a WIFI module, and a remote control module, thereby further improving intelligent operation, meeting user needs, and enhancing the user experience.
