Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of water heaters, and in particular to a high-efficiency integrated water heater and water heater system. Background Technology
[0002] Most standard-sized homes now have water heaters installed to meet the bathing needs of the whole family. After each shower, the used hot water needs to be replenished, requiring the water heater to heat it up again.
[0003] In the current context of energy conservation and emission reduction, air source water heaters have become a trend. An air source water heater consists of an outdoor unit and a water tank. The system absorbs heat from the outside environment through refrigerant to produce hot water. The low-temperature, low-pressure refrigerant flows into the evaporator of the outdoor unit, absorbs heat from the air, and becomes high-temperature refrigerant. It then flows into the microchannels of the water tank and releases heat to heat the water.
[0004] At the same time, a lot of water vapor will accumulate in the bathroom after showering, and it often stays there for several hours. When you enter the bathroom again at this time, the skin and breathing will feel uncomfortable due to the high moisture content in the air. Moreover, bacteria can easily grow in a long-term humid environment. Therefore, it is also necessary to dehumidify the bathroom after showering.
[0005] In daily life, a common way to deal with humidity is to use exhaust fans, which rely on air circulation to directly extract humid air from the room. Although this can quickly remove some of the moisture in the air, its overall dehumidification effect on the room is limited and it is difficult to completely remove the moisture. At the same time, it is affected by the outdoor weather. If it is a cloudy or rainy day with high humidity, the dehumidification effect of the ventilation will be greatly reduced.
[0006] Another common approach is to use a dehumidifier to dehumidify the bathroom environment. This method is more thorough, utilizing the refrigerant inside the dehumidifier to absorb the heat of water vapor and condense it to remove moisture. The dehumidifier draws low-temperature, low-pressure refrigerant into the evaporator, continuously drawing air from the room through it. Water vapor condenses on the evaporator, reducing the air's moisture content. After heat exchange, the high-temperature refrigerant passes through the compressor, condenser, and throttling device, returning to a low-temperature, low-pressure state before entering the evaporator to dehumidify the air.
[0007] In summary, the needs for replenishing hot water and removing moisture often occur simultaneously after each shower; moreover, the heating process of an air source heat pump water heater is very similar to the dehumidification process of a dehumidifier. When producing hot water, the refrigerant's effective work process is heat release, while during dehumidification, the refrigerant's effective work process is heat absorption. These two processes complement each other, and operating them independently would result in energy waste.
[0008] Therefore, how to design a high-efficiency integrated water heater and water heater system that can meet both hot water production and dehumidification needs with the same product is a technical problem that the industry urgently needs to solve. Utility Model Content

[0044] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0045] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.
[0046] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0047] Currently, the heating process of a water heater and the dehumidification process of a dehumidifier are complementary. Operating the water heater and dehumidifier independently would result in energy waste. To address this issue, the design concept of this invention is to combine the hot water tank of a water heater with the dehumidification module of a dehumidifier, forming a high-efficiency integrated water heater. This allows the invention to simultaneously execute both hot water and dehumidification modes, avoiding the energy waste caused by operating the two modes independently.
[0048] Based on the above design concept, this utility model proposes a high energy efficiency ratio integrated water heater, including a hot water tank and a dehumidification module;
[0049] The dehumidification module has at least two evaporators connected in parallel, and ventilation ducts that are connected to the indoor and outdoor areas respectively.
[0050] The evaporator is connected to the hot water tank, and at least one reversing valve is installed on the connecting pipe between the evaporator and the hot water tank.
[0051] The high-efficiency water heater proposed in this utility model switches the operating mode of the high-efficiency water heater by adjusting the conduction state of the ventilation pipe and the reversing valve.
[0052] By setting up the aforementioned reversing valve and ventilation duct, this utility model can reasonably control the refrigerant's work process, enabling the refrigerant to effectively perform work during both the heat release and heat absorption processes, thereby improving the heat utilization rate of the entire water heater system.
[0053] Specifically, the dehumidification module of this utility model includes a first evaporator and a second evaporator. The two ends of the first evaporator are respectively connected to the hot water tank, and the two ends of the second evaporator are respectively connected to the connecting pipes between the first evaporator and the hot water tank.
[0054] A first reversing valve and a second reversing valve are installed at the connection between the first evaporator, the second evaporator, and the hot water tank.
[0055] Please see Figure 1This is a schematic diagram of a preferred embodiment of the high-efficiency integrated hot water heater proposed in this utility model. In this embodiment, the dehumidification module is equipped with two evaporators, namely evaporator 1 and evaporator 2, which are also the first evaporator and the second evaporator mentioned above. Both evaporators are connected to the condenser in the hot water tank, i.e., attached... Figure 1 Microchannel condenser in the middle;
[0056] A reversing valve is installed at each of the two nodes connecting the first evaporator, the second evaporator, and the hot water tank. Figure 1 The first and second reversing valves in the system control the flow path of the refrigerant in the hot water tank and dehumidification module by controlling their on / off states. Simultaneously, in conjunction with the ventilation duct, they control the airflow to and from the outdoor and indoor areas, allowing the system to operate in different modes. Different operating modes require different refrigerant work. For example, in hot water mode, the effective work process of the refrigerant in the condenser is heat release; in dehumidification mode, the effective work process of the refrigerant in the evaporator is heat absorption. Through the above-mentioned design, the system can rationally allocate the use of refrigerant, ensuring that the refrigerant effectively performs work in both heat release and heat absorption processes, thereby improving the overall heat utilization rate of the water heater system.
[0057] Specifically, through the aforementioned first reversing valve, second reversing valve, and ventilation duct, this utility model can operate in four operating modes: dehumidification mode, hot water production mode, first combined operation mode, and second combined operation mode. Here, the first combined operation mode is the simultaneous execution of hot water production mode and dehumidification mode, and the second combined operation mode is the simultaneous operation of hot water production mode, dehumidification mode, and bathroom heater mode. The bathroom heater mode is the working mode when the user uses hot water for showering.
[0058] The first and second reversing valves mentioned above are both bidirectional electronic expansion valves, which can adaptively adjust the flow of refrigerant and control the direction of refrigerant flow through their conduction state, so that this utility model can operate in different working modes.
[0059] The above four modes can be set according to the daily usage habits of the bathroom. Before showering, the water heater needs to store hot water. At this time, it first enters the hot water production mode to start preparing hot water. During the shower, the second combined operation mode is activated. At this time, the bathroom heater function is turned on, and the hot water production mode is used to replenish the hot water tank and dehumidify through the dehumidification module. After showering, the hot water is consumed and the indoor humidity is high. The first combined operation mode can be activated. At this time, it is not necessary to turn on the bathroom heater function. It is only necessary to use the hot water tank and the dehumidification module to perform the hot water production and dehumidification functions simultaneously. After completing the hot water production mode, this utility model can be converted into an independent dehumidification mode to further remove indoor humidity.
[0060] The working modes of this utility model will be described below;
[0061] The high-efficiency water heater proposed in this utility model has a dehumidification mode;
[0062] In dehumidification mode, the first and second reversing valves control the refrigerant to flow only between the first and second evaporators.
[0063] The dehumidification modes mentioned above are specifically divided into: independent dehumidification mode, bathroom heater dehumidification mode, and independent bathroom heater mode.
[0064] In independent dehumidification mode, the dehumidification module is connected to the outdoor ventilation duct, and the hot air generated by the second evaporator is blown outdoors.
[0065] In the dehumidification mode of the bathroom heater, the dehumidification module is connected to the indoor ventilation duct, and the hot air generated by the second evaporator is blown into the room;
[0066] In independent bathroom heater mode, the dehumidification module is connected to both indoor and outdoor ventilation ducts, and the first evaporator switches to draw air from the outside, while the hot air generated by the second evaporator is blown into the room.
[0067] Please see Figure 2 This is a schematic diagram of the refrigerant flow direction in the dehumidification mode of this utility model. At this time, the first reversing valve controls the upper pipe of the first evaporator and the upper pipe of the second evaporator to be connected, and both are disconnected from the condenser in the hot water tank. The second reversing valve controls the lower pipe of the first evaporator and the lower pipe of the second evaporator to be connected, and both are disconnected from the condenser in the hot water tank.
[0068] At this time, the first evaporator and the second evaporator are completely disconnected from the condenser in the hot water tank. The refrigerant will only circulate between the first evaporator and the second evaporator. The hot water tank does not participate in the circulation, that is, it does not execute the hot water production mode. At this time, the present invention works in the dehumidification mode, and the second evaporator acts as the condenser.
[0069] When the ventilation duct connects the dehumidification module to the outside and the hot air generated by the second evaporator is blown to the outside, this utility model works in independent dehumidification mode. It can be used after hot water production is completed and when the bathing process is not underway. At this time, there is no need for the condenser to provide heat to the room. The room can be dehumidified by the first evaporator through the refrigerant.
[0070] When the ventilation duct connects the dehumidification module to the room and the hot air generated by the second evaporator is blown into the room, this utility model works in the bathroom heater dehumidification mode. The second evaporator acts as a condenser, which can generate hot air and blow the hot air into the room through the ventilation duct to ensure the indoor temperature. At the same time, the first evaporator starts to dehumidify the room.
[0071] When the ventilation duct connects the dehumidification module to both indoor and outdoor ventilation ducts, and the first evaporator is switched to draw air from the outside while the hot air generated by the second evaporator is blown into the room, this utility model operates in independent bathroom heater mode. At this time, the second evaporator mainly plays a role, generating hot air and blowing it into the room to preheat the bathroom.
[0072] As can be seen from the above settings, in dehumidification mode, the first evaporator and the second evaporator can also independently form a refrigeration or heating system. At the same time, in combination with the direction of the ventilation duct, the present invention can operate in independent dehumidification mode, bathroom heater dehumidification mode and independent bathroom heater mode respectively, so that the present invention can adapt to various different usage scenarios.
[0073] Furthermore, the high-efficiency water heater proposed in this utility model also has a hot water production mode;
[0074] In hot water production mode, the first reversing valve and the second reversing valve control the flow of refrigerant between the first evaporator and the hot water tank and the second evaporator and the hot water tank.
[0075] The ventilation duct controls the first and second evaporators to draw air from the outside simultaneously.
[0076] Please see Figure 3 This is a schematic diagram of the refrigerant flow direction in the hot water production mode of this utility model. At this time, the first reversing valve and the second reversing valve connect the connecting pipes of the first evaporator and the condenser, as well as the connecting pipes of the second evaporator and the condenser. The refrigerant can circulate between the first evaporator and the condenser, and between the second evaporator and the condenser. The working principle of the hot water tank is the same as that of the traditional hot water tank. The first evaporator and the second evaporator draw air from the outside. When the refrigerant passes through the condenser in the hot water tank, it exchanges heat with the cold water in the hot water tank, raising the temperature of the cold water and turning it into hot water, which is then stored in the hot water tank to realize the hot water production function, so that hot water can be used in the bathroom heater mode.
[0077] Furthermore, the high-efficiency integrated water heater proposed in this utility model also has a first combined operation mode;
[0078] In the first combined operation mode, the first reversing valve and the second reversing valve control the flow of refrigerant between the first evaporator and the hot water tank and the second evaporator and the hot water tank;
[0079] The ventilation duct controls the first and second evaporators to draw air from the room simultaneously.
[0080] The first combined operation mode here refers to the simultaneous execution of the dehumidification mode and the hot water production mode mentioned earlier. Please refer to [link / reference]. Figure 4This is a schematic diagram of the refrigerant flow in the first combined operation mode of this utility model. In this first combined operation mode, the refrigerant flow path is the same as in the hot water production mode. Only the ventilation pipe needs to be adjusted to change the first and second evaporators to draw air from the room. At this time, the working principle of the first and second evaporators is the same as that of the dehumidification module in the traditional structure. The working principle of the condenser in the hot water tank is the same as that of the condenser in the traditional structure. The main difference is:
[0081] In the traditional mode, the hot water tank and the dehumidification module are set up separately and operate in different modules. The hot water tank actually contains both a condenser and an evaporator, but only the condenser functions to exchange heat and heat the cold water in the tank. However, the refrigerant in the evaporator can only exchange heat with the air to absorb heat. In this process, the effective work done by the refrigerant is heat release, and the heat absorption process of the evaporator is completely wasted. Similarly, the dehumidification module also has a condenser and an evaporator, but only the evaporator functions to exchange heat and dehumidify. In this process, the effective work done by the refrigerant is heat absorption, and the heat release process of the condenser is completely wasted.
[0082] However, under the above-mentioned configuration of this application, after the hot water tank and the dehumidification module are combined together, the useless evaporator part of the hot water tank is converted into the first evaporator and the second evaporator in the dehumidification module for dehumidification, and the useless condenser part of the dehumidification module is converted into the condenser in the hot water tank for hot water production. At this time, both the heat release process and the heat absorption process of the refrigerant are effective. That is, under this mode, the present invention can significantly improve the energy utilization rate.
[0083] The first and second combined operation modes are the two most important operation modes of this utility model. Under these two operation modes, the heat absorption and heat release processes of the refrigerant can be fully utilized. However, the core idea of this utility model is not simply to propose the above two modes, but to propose a high energy efficiency integrated water heater that can adapt to the operation of multiple operation modes, meet the applicable needs of various scenarios, and improve the energy utilization rate.
[0084] Furthermore, the high-efficiency integrated water heater proposed in this utility model has a second combined operation mode;
[0085] In the second combined operation mode, the first reversing valve and the second reversing valve control the flow of refrigerant between the first evaporator and the hot water tank and between the first evaporator and the second evaporator;
[0086] The ventilation duct controls the first evaporator to draw air from the room and controls the hot air generated by the second evaporator to blow into the room.
[0087] The second combined operation mode here refers to the simultaneous execution of the dehumidification mode, hot water mode, and bathroom heater mode mentioned earlier. Please refer to [link / reference]. Figure 5 This is a schematic diagram of the refrigerant flow direction in the second combined operation mode of this utility model. In this second combined operation mode, the refrigerant flow path is similar to that in the first combined operation mode. The main difference lies in the refrigerant flow direction at the second evaporator. By setting the first and second reversing valves, the refrigerant in the second evaporator is controlled to flow to the first evaporator, which is opposite to the refrigerant flow direction in the first combined operation mode. With this setting, the second evaporator actually acts as a condenser, which can work together with the condenser in the hot water tank to generate heat. At this time, through the setting of the ventilation pipe, the first evaporator can draw air from the water vapor in the room (i.e., the bathroom) to absorb heat and exchange heat with the refrigerant. This part of the refrigerant will enter the condenser and the second evaporator respectively. The refrigerant entering the condenser exchanges heat with the cold water in the hot water tank to produce hot water. The refrigerant entering the second evaporator exchanges heat with the air in the room and generates hot air which is blown into the room, thereby realizing the above-mentioned bathroom heater function.
[0088] As can be seen, this utility model, through the above-mentioned settings, realizes a combined system of dehumidification module and hot water tank, and, in conjunction with ventilation ducts, regulates the ambient temperature. This solves the drawbacks of individual home appliances during use, such as dehumidifiers causing indoor ambient temperature to rise and comfort to decrease, and water heaters wasting cooling capacity of the outdoor unit.
[0089] The above four modes can be collectively referred to as three operating conditions. The first operating condition is independent dehumidification, which is the dehumidification mode mentioned above. In this case, the first evaporator and the second evaporator form a system, and the ventilation duct forms a circulation with the indoor environment to perform dehumidification.
[0090] The second operating condition is independent hot water production, which is the hot water production mode mentioned above. In this case, both the first and second evaporators are used as evaporator components, and the condenser is used as a condenser component to form a system. It draws air from the outside and does not affect the indoor ambient temperature and humidity.
[0091] The third operating condition is the combined operating condition, which is the first combined operation mode and the second combined operation mode mentioned above. In this case, the first evaporator and the second evaporator can form an evaporator component and together with the condenser to form a system. Alternatively, the second evaporator and the condenser can form a condenser component and together with the first evaporator to form a system. Based on the second operating condition, the indoor temperature and humidity are controlled by circulating from the room.
[0092] This utility model can be equipped with a corresponding operation panel to control the execution of the above four modes respectively, and can also be used to control the opening and closing of the dehumidification function, the bathroom heater function, and the hot water production function.
[0093] The system automatically starts and stops heating based on the water temperature set for each time period.
[0094] By using the opening and closing of the first and second reversing valves, as well as the switching of the ventilation duct, the functions of hot water production, bathroom heater, and dehumidification can be turned on and off at any time, and can be combined arbitrarily without restriction. According to the combination of function opening and closing, this utility model can automatically switch, and the dehumidification mode and hot water production mode also support timed shutdown function.
[0095] In addition, this utility model can also realize the function of drying clothes. It can set a folding clothes rack at the air outlet of the dehumidification module, so that clothes can be dried at the same time while dehumidifying the bathroom.
[0096] Please see Figure 6 This utility model can also adopt a one-to-two outdoor unit configuration, connecting the condenser in the hot water tank, the evaporator in the dehumidification module, and the evaporator in the compressor in series. By controlling the opening and closing of each reversing valve, one of them can be controlled to not participate in the system operation, thereby realizing three operating modes: dehumidification mode, hot water mode, and combined mode (including the first combined operation mode and the second combined operation mode).
[0097] Furthermore, in this utility model, when setting the above modules, since the humidity and temperature in the bathroom are high and the gas rises, the dehumidification module can be installed in the bathroom using a ceiling-mounted method, which can more thoroughly remove indoor moisture, avoid moisture residue, and save space; at the same time, the fins of the first evaporator and the second evaporator in the dehumidification module are arranged at an angle, and with the help of the guide groove, the water is guided to the outdoor unit for discharge, preventing condensate from dripping back into the room;
[0098] To adapt to the high humidity environment of the bathroom, the aforementioned fins need to be made of gold-colored anti-corrosion fins to extend their service life. At the same time, an additional layer of grille is added for concealment to ensure aesthetics.
[0099] This invention can also design air vents in the middle and bottom of the bathroom to introduce the hot air blown out by the second evaporator into the room. On the one hand, this can help accelerate dehumidification, and on the other hand, it can provide a bathroom heater function to increase the bathroom temperature. At the same time, the air vents need to be set to avoid blowing directly on people.
[0100] Furthermore, this utility model also proposes a water heater system that has the aforementioned high energy efficiency integrated water heater.
[0101] Compared with the prior art, the present invention has the following beneficial effects:
[0102] This invention rationally utilizes the two complementary processes of dehumidification and hot water production, integrating the hot water tank and the dehumidification module. This allows the refrigerant to simultaneously perform work during both the heat release and heat absorption processes, enabling the invention to meet both hot water production and dehumidification needs at the same time, thus improving the heat utilization rate of the entire water heater system.
[0103] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
