[0002] In the prior art, with the continuous improvement of living conditions and the continuous improvement of living standards, modern families have higher requirements for the comfort of indoor environment. As a special functional area in the home, the bathroom environment comfort is particularly concerned. In the bathroom, due to the frequent generation of a large amount of water vapor in daily activities such as showering and bathing, the indoor humidity rises sharply. This increase in humidity not only reduces the user's comfort experience, but also may cause a series of problems, such as mold growth, damp objects, etc.

[0003] To solve the problem of damp bathroom, some users choose to install independent dehumidifiers. However, independent dehumidifiers are usually large in size, occupying valuable bathroom space, especially for smaller bathrooms, which will appear more crowded.

In particular, installing a drain pipe in a renovated bathroom requires grooving the wall or floor, which is time-consuming and laborious. If the drain pipe is not installed properly or the drainage is not smooth, it may cause water leakage, equipment damage and other problems. Utility Model Content

[0011] A further solution is that the radius of the water pumping wheel is smaller than half the height of the first fin or the second fin.

[0012] In order to prevent condensed water from splashing, a water baffle is provided between the first fin and the second fin, and the water baffle is used to guide the water-lifting device to lift up the condensed water that has not fallen on the first fin and the second fin and flow it back into the water receiving tray.

DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Example 1.

[0029] First, as Figures 5 to 9 As shown, this embodiment provides a bathroom heater 200, including a housing 50 and a dehumidification component 100 disposed in the housing 50. Specifically, the housing 50 is provided with an air inlet 51, a first air outlet 52, and a second air outlet 53; a first air valve 54 is disposed in the first air outlet 52, and a second air valve 55 is disposed in the second air outlet 53, the first air valve 54 is used to selectively open or close the first air outlet 52, and the second air valve 55 is used to selectively open or close the second air outlet 53; a fan 56 is disposed in the housing 50; and the air inlet 51 is connected to the first air outlet 52 to form an air circulation channel ( Fig. 9 The air inlet 51 is connected to the second air outlet 53 to form an exhaust passage ( Figure 8 The dashed line B).

[0030] In this embodiment, the dehumidification component 100 is integrated inside the casing 50, and is used to provide a dehumidification function for the bathroom heater 200. That is, the main function of the dehumidification component 100 is to condense the water vapor in the inhaled humid air into water, and lift it to the condenser fins for evaporation through a water pumping device, and finally discharge it to the outside through an exhaust duct to achieve efficient dehumidification. The detailed structure will be introduced in detail later.

[0031] The bathroom heater 200 provided in the first aspect of the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0032] In the specific implementation, in order to improve the overall aesthetics and installation stability of the bathroom heater 200, it can be installed in conjunction with the bathroom ceiling 60 during the installation process, for example, Figure 6 As shown, the housing 50 of the bathroom heater 200 can be fixed on the bathroom wall by means of a mounting bracket 57, and the mounting bracket 57 can be hidden inside the suspended ceiling 60 so that the bathroom heater 200 is integrated with the suspended ceiling 60. This installation method not only enhances the visual coordination and makes the bathroom heater 200 more integrated with the bathroom decoration style, but also avoids the exposure of the bathroom heater 200, reduces the risk of bumps and damages, and improves safety.

[0033] When working, Figure 8 and Fig. 9 As shown, illustratively:

[0034] When dehumidification is required, the fan 56 is controlled to start, and the first air valve 54 is opened to conduct the air circulation channel ( Fig. 9 The dotted line C in the figure) and the second air valve 55 is closed to cut off the exhaust passage ( Figure 8The dotted line B in the figure) indicates that the humid air in the bathroom will enter the casing 50 from the air inlet 51, flow through the dehumidification component 100 for dehumidification, and the dry air after dehumidification will be blown back to the bathroom through the first air outlet 52, thereby achieving dehumidification of the bathroom, preventing mold growth, keeping items dry, and improving user comfort and health.

[0035] When ventilation is required, the fan 56 is controlled to start, and the second air valve 55 is opened to connect the exhaust passage ( Figure 8 The dotted line B in the figure) and at the same time close the first air valve 54 to cut off the air circulation channel ( Fig. 9 The dotted line C in the figure), at this time, the air in the bathroom will enter the casing 50 from the air inlet 51, and finally be directly discharged to the outside through the second air outlet 53, so as to realize ventilation of the bathroom, remove odor and keep the air fresh.

[0036] In addition, in this embodiment, the bathroom heater 200 can also be integrated with a PTC heater. The PTC heater (not shown) is installed at the outlet of the air circulation channel. When warm air is needed, the fan 56 is controlled to start, and the first air valve 54 is opened to conduct the air circulation channel, and the second air valve 55 is closed to cut off the exhaust channel. At this time, air will enter the bathroom heater 200 from the air inlet 51, and after being heated by the PTC heater, it will be blown out through the first air outlet 52 to form warm air to provide warmth for the bathroom. Compared with the traditional electric heating wire heater, the PTC heater can respond to temperature changes more quickly and can maintain the set temperature more stably to avoid the temperature being too high or too low.

[0037] In another example, if Figure 6 As shown, the vent assembly 52a can be set on the ceiling 60 of the bathroom. In specific implementation, the vent assembly 52a can be conveniently set at the position desired by the user on the ceiling 60. For example, according to the layout of the bathroom and the needs of the user, the vent assembly 52a can be set in the center of the bathroom, above the shower area or other suitable positions. Then, the first air outlet 52 of the bathroom heater 200 is connected to the vent assembly 52a through a pipe. When the bathroom heater 200 is in dehumidification mode, the dehumidified and dried air will be transported to the vent assembly 52a through the pipe, and then evenly distributed to the entire bathroom through the vent assembly 52a, so as to achieve more uniform air circulation, avoid local dryness or humidity, and improve the dehumidification effect.

[0038] Below, the dehumidification component 100 provided in the second aspect of the embodiment of the present application will be described in detail with reference to the accompanying drawings.

[0039] like Figures 1 to 3As shown, the dehumidification component 100 includes an evaporator 10 and a condenser 20, and a water receiving tray 30 for receiving condensed water generated by the evaporator 10 and the condenser 20. The condenser 20 includes a first fin 21 and a second fin 22 that are spaced apart. A water lifting device 40 is rotatably provided in the water receiving tray 30. The water lifting device 40 is located between the first fin 21 and the second fin 22, and is used to lift the condensed water in the water receiving tray 30 and spread it onto the first fin 21 and the second fin 22.

[0040] During specific implementation, the evaporator 10 utilizes the circulation of the refrigerant to make the surface temperature of the evaporator 10 lower than the dew point temperature of the air. When the air flows through the evaporator 10, the water vapor in the air encounters the surface of the evaporator 10 with a lower temperature and is condensed into liquid water, forming tiny water droplets. These water droplets will adhere to the surface of the evaporator 10. As the dehumidification process proceeds, more and more water droplets gather together and eventually drop into the water receiving tray 30 below the evaporator 10 due to gravity. At the same time, the condenser 20 changes the refrigerant from a gaseous state to a high-pressure liquid state. Heat is released in this process. The released heat will heat the air after dehumidification to compensate for the heat loss during the air dehumidification process, so that the temperature of the blown air will not be too low, thereby improving user comfort.

[0041] Among them, a water lifting device 40 is arranged inside the water receiving tray 30, and the water lifting device 40 is located between the first fin 21 and the second fin 22. Its function is to lift the condensed water in the water receiving tray 30 and evenly spread it on the first fin 21 and the second fin 22. In this embodiment, the water lifting device 40 can adopt various forms, such as a small water pump, an impeller, etc. The lifted condensed water is evaporated using the heat of the fins (21, 22), and the evaporated water vapor will be directly discharged to the outside with the air flow in the exhaust channel. This does not require a special external drain pipe for the water receiving tray 30, and there is no need to separately groove the wall and floor for the external drain pipe. It is more convenient to install and use, especially suitable for bathroom spaces that have been decorated, avoiding cumbersome installation processes and damage to walls and floors, and also reducing the risk of problems such as leakage.

[0042] In addition, when the bathroom heater 200 is used in a hot and humid environment such as in summer, the heat released by the condenser 20 may cause the exhaust air temperature to rise, affecting the user experience. By spraying condensed water onto the first fin 21 and the second fin 22, the evaporation of the condensed water can be used to take away part of the heat, thereby lowering the fin temperature, and then lowering the exhaust air temperature, making the blown air cooler and more comfortable, thereby improving the user experience. Moreover, spraying condensed water onto the first fin 21 and the second fin 22 can absorb part of the heat released by the condenser 20 and lower the temperature of the condenser 20, which helps to improve the condensation efficiency of the refrigerant and make the refrigerant change from gas to liquid faster, thereby improving the refrigeration efficiency of the entire dehumidification assembly 100. While achieving better dehumidification effect, it can also reduce energy consumption, save energy and protect the environment.

[0043] In some embodiments, Figure 1 and Figure 3 As shown, the water pumping device 40 includes a water pumping wheel 41 arranged in the water receiving tray 30 and a driving motor 42 arranged on the outer wall of the water receiving tray 30. The output shaft of the driving motor 42 passes through the outer wall of the water receiving tray 30 and is coaxially connected to the water pumping wheel 41.

[0044] In specific implementation, the water-lifting wheel 41 can be in various forms, such as a centrifugal impeller, the blades of which are bent outwards. When the impeller rotates, the condensed water will be thrown to the outer edge of the impeller, and move upward along the outer edge of the impeller, and finally be lifted out of the water receiving tray 30. The material of the water-lifting wheel 41 can be plastic or metal, for example, corrosion-resistant, high-strength engineering plastic or stainless steel. In order to improve the water-lifting efficiency, in this embodiment, the outer surface of the water-lifting wheel 41 is also designed with a rib structure for guiding the water flow. The rib structure can make the condensed water form a more regular water flow on the surface of the water-lifting wheel 41, reduce turbulence and energy loss, so as to more effectively lift the condensed water from the water receiving tray 30 and transport it to a certain height, so as to better spread it on the first fin 21 and the second fin 22, thereby improving the evaporation efficiency and cooling effect of the condensed water.

[0045] In some embodiments, Figure 3 and Figure 8As shown, the water pumping wheel 41 is vertically arranged between the first fin 21 and the second fin 22, and the axial direction of the water pumping wheel 41 is perpendicular to the length direction of the condenser 20. With this structural design, on the one hand, the water pumping device 40 can occupy less space, which is conducive to the overall compact design; on the other hand, the vertically arranged water pumping wheel 41 can more effectively use the centrifugal force generated by the rotation to lift the condensed water to a higher position, thereby increasing the head, that is, a higher head means that the condensed water can be sprayed to a larger range, more evenly and more evenly spread on the surface of the first fin 21 and the second fin 22, enhancing the spraying effect, and effectively improving the evaporation efficiency and cooling effect of the condensed water. In addition, the structure in which the axial direction of the water pumping wheel 41 is perpendicular to the length direction of the condenser 20 enables the water flow trajectory generated by the rotation of the water pumping wheel 41 to cover the fin surface of the condenser 20 to the greatest extent, ensuring that the condensed water can be more evenly spread to various areas in the length direction of the first fin 21 and the second fin 22.

[0046] In some embodiments, Figure 4 As shown, the water-lifting wheel 41 includes a circular first part 411 and an annular second part 412, and a plurality of spokes 413 connected between the first part 411 and the second part 412; the rib structure includes a plurality of convex ribs 414 protruding from the surface of the second part 412, and each of the convex ribs 414 is spirally arranged in an annular direction at intervals along the center of the second part 412.

[0047] With this structural design, on the one hand, when the water-pumping wheel 41 rotates, the spirally annularly spaced ribs 414 can guide the condensed water to move upward along the outer edge of the water-pumping wheel 41, forming a more regular water flow, reducing turbulence and energy loss, and improving water pumping efficiency. On the other hand, the water-pumping wheel 41 is divided into a first part 411 and a second part 412 and connected by spokes 413, so that a gap can be left in the middle of the water-pumping wheel 41, which can effectively reduce the windward area of ​​the water-pumping wheel 41, thereby reducing the force of the airflow on the water-pumping wheel 41 during dehumidification, guiding the airflow to pass through the water-pumping wheel 41 smoothly, greatly reducing the interference of the airflow on the rotation posture of the water-pumping wheel 41, and maintaining the stable rotation of the water-pumping wheel 41.

[0048] In some embodiments, Fig. 9 As shown, in order to optimize the spatial layout, a mounting bracket 31 for supporting the evaporator 10 and the condenser 20 is provided in the water receiving tray 30 , and the output shaft of the driving motor 42 is located between the condenser 20 and the bottom surface of the water receiving tray 30 .

[0049] Specifically, by integrating the mounting bracket 31 into the water receiving tray 30, the space of the water receiving tray 30 can be effectively utilized, avoiding the extra space occupied by the dehumidification component 100, making the dehumidification component 100 more compact, improving the space utilization rate, and being easier to integrate into the equipment such as the bathroom heater 200; and by setting the output shaft of the driving motor 42 between the condenser 20 and the bottom surface of the water receiving tray 30, the shielding of the first fin 21 and the second fin 22 by the water receiving tray 30 can be minimized, ensuring the full contact between the fin and the air, improving the heat dissipation efficiency, and improving the performance and dehumidification effect of the condenser 20. In this embodiment, the radius of the water wheel 41 is less than half the height of the first fin 21 or the second fin 22.

[0050] In some embodiments, Figure 1 and Figure 3 As shown, a water baffle 32 is provided between the first fin 21 and the second fin 22 , and the water baffle 32 is used to guide the water lifting device 40 to lift up the condensed water that has not fallen on the first fin 21 and the second fin 22 and flow it back into the water receiving tray 30 .

[0051] During specific implementation, after the water-lifting device 40 lifts up the condensed water, a part of the condensed water will fall on the first fin 21 or the second fin 22 to evaporate; another part of the condensed water may splash to places outside the fins due to inertia or other reasons, such as the inside or outside of the bathroom heater 200, which may cause damage to other electrical components, and the water baffle 32 can effectively block the splashing condensed water and guide it to flow back into the water receiving tray 30, avoiding the splashing of condensed water and preventing it from contacting electronic components.

[0052] In some embodiments, Figure 2 and Fig. 9 As shown, it also includes a controller, a first liquid level sensor 33 and a second liquid level sensor 34. The first liquid level sensor 33 is electrically connected to the controller, and is used to detect a first threshold height of the liquid level in the water receiving tray 30; the second liquid level sensor 34 is electrically connected to the controller, and is used to detect a second threshold height of the liquid level in the water receiving tray 30; when the first liquid level sensor 33 detects that the liquid level in the water receiving tray 30 reaches the first threshold height, the controller controls the water pumping device 40 to start working; when the second liquid level sensor 34 detects that the liquid level in the water receiving tray 30 drops to the second threshold height, the controller controls the water pumping device 40 to stop working.

[0053] In specific implementation, the controller can be a microprocessor or a single-chip microcomputer, etc., which is used to receive signals from the liquid level sensors 33 and 34, and control the start and stop of the water pumping device 40 according to a preset program. When the dehumidification component 100 is working, the condensed water generated by the evaporator 10 and the condenser 20 will flow into the water receiving tray 30. When the liquid level in the water receiving tray 30 reaches the first threshold height, the first liquid level sensor 33 will detect the liquid level change and send a signal to the controller. After receiving the signal, the controller will control the water pumping device 40 to start working and lift the condensed water in the water receiving tray 30. As the water pumping device 40 works, the liquid level in the water receiving tray 30 will gradually decrease. When the liquid level drops to the second threshold height, the second liquid level sensor 34 will detect the liquid level change and send a signal to the controller. After receiving the signal, the controller will control the water pumping device 40 to stop working.

[0054] In this way, the control method based on the liquid level sensor can realize automatic control of the water pumping device 40 without manual intervention, which is more convenient and intelligent. That is, the water pumping device 40 will only be started when needed, avoiding unnecessary energy consumption, improving the efficiency of the dehumidification component 100, and being more energy-saving and environmentally friendly.

[0055] The dehumidification assembly and bathroom heater provided in this embodiment lift the condensed water through the water lifting device and transport it to the fin surface of the condenser, so that the condensed water absorbs heat and evaporates on the fin surface and is discharged outside the bathroom heater, thereby realizing condensed water treatment without drain pipes, avoiding grooving in walls and floors and exposed drain pipes, and simplifying the installation process and installation costs.
