Description

Technical Field

[0001] The invention relates to the technical field of water heaters, in particular to a high energy efficiency integrated water heater and a water heater system. Background Art

[0002] At present, most regular households have installed water heaters to meet the bathing needs of the whole family. After each bath, the used hot water needs to be replenished, and the water heater needs to be reheated at this time;

[0003] In the current context of energy conservation and emission reduction, air-energy water heaters have become a trend; air-energy water heaters consist of an outdoor unit and a water tank, and the system absorbs external heat through refrigerant to produce hot water; low-temperature and low-pressure refrigerant flows into the outdoor unit evaporator, absorbs heat from the air, becomes high-temperature refrigerant and flows into the microchannels of the water tank, releasing heat to heat the water.

[0004] At the same time, a lot of water vapor will accumulate in the bathroom after bathing, and it often stays for several hours. When you enter the bathroom again at this time, the skin and breathing will feel uncomfortable due to the high water content in the air, and bacteria are very easy to breed in a long-term humid environment. Therefore, the bathroom also needs to be dehumidified after bathing;

[0005] To solve the problem of moisture in daily life, a common scenario is to use a ventilation fan, which relies on air circulation to directly extract the humid air in the room. Although it can quickly remove some of the moisture in the air, the dehumidification effect on the whole 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 cloudy and rainy outside and the humidity is high, the ventilation and dehumidification effect will be greatly reduced.

[0006] Another common situation is to use a dehumidifier to dehumidify the bathroom environment. The dehumidification effect is more thorough, and the refrigerant in the dehumidifier absorbs the heat of water vapor to condense and dehumidify. The dehumidifier allows low-temperature and low-pressure refrigerant to flow into the evaporator. At this time, air is continuously drawn from the room through the evaporator. Water vapor condenses on the evaporator when it is cold, and the moisture content of the air is reduced; the high-temperature refrigerant after heat exchange passes through the compressor, condenser and throttling device, and then becomes a low-temperature and low-pressure refrigerant again, and enters the evaporator to dehumidify the air.

[0007] In summary, after each bath, the two needs of replenishing hot water and removing moisture often occur at the same time; and the heating process of the air-energy water heater is very similar to the dehumidification process of the dehumidifier. When making hot water, the effective work process of the refrigerant is heat release, and in dehumidification, the effective work process of the refrigerant is heat absorption. The two processes just complement each other, and independent operation will waste energy.

[0008] Therefore, how to design a high energy efficiency all-in-one hot water machine and water heater system that can meet both hot water production and dehumidification needs through the same product is a technical problem that the industry urgently needs to solve. Summary of the invention

[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0046] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0047] At present, the heating process of the water heater and the dehumidification process of the dehumidifier complement each other. If the water heater and the dehumidifier are operated independently, there will be a problem of energy waste. Based on this problem, the design idea of ​​the present invention is to combine the hot water tank in the water heater with the dehumidification module in the dehumidifier to form a high energy efficiency ratio hot water integrated machine in the present invention, so that the present invention can execute the hot water mode and the dehumidification mode at the same time, avoiding the problem of energy waste caused by the independent operation of the two modes.

[0048] Based on the above design ideas, the present invention proposes a high energy efficiency integrated hot water machine, including a hot water tank and a dehumidification module;

[0049] The dehumidification module has at least two evaporators arranged in parallel, and ventilation pipes 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 arranged on the connecting pipeline between the evaporator and the hot water tank;

[0051] The high energy efficiency ratio integrated water heater proposed by the present invention switches the operation mode of the high energy efficiency ratio integrated water heater by adjusting the conduction state of the ventilation pipeline and the reversing valve;

[0052] The present invention can reasonably control the work process of the refrigerant through the arrangement of the reversing valve and the ventilation pipeline, so that the refrigerant can be transformed into effective work in both the heat release process and the heat absorption process, thereby improving the heat utilization rate of the entire water heater system.

[0053] Specifically, the dehumidification module in the present invention includes a first evaporator and a second evaporator, both ends of the first evaporator are respectively connected to a hot water tank, and both 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 provided at the connection between the first evaporator, the second evaporator, and the hot water tank.

[0055] See also Figure 1 , which is a schematic diagram of the structure of the high energy efficiency ratio water heater in a preferred embodiment of the present invention. In this embodiment, two evaporators are arranged in the dehumidification module, namely, evaporator 1 and evaporator 2, which are the first evaporator and the second evaporator mentioned above. Both evaporators are connected to the condenser in the water heating tank, which is the attached Figure 1 Microchannel condenser in;

[0056] A reversing valve is provided at two nodes where the first evaporator, the second evaporator, and the hot water tank are connected to each other. Figure 1 The first reversing valve and the second reversing valve in the dehumidification module can control the flow path of the refrigerant in the water heating tank and the dehumidification module by controlling the conduction state of the two reversing valves. At the same time, the ventilation pipeline is cooperated to control the outdoor and indoor air outlet and air intake, so that the present invention can work in different operation modes. In different operation modes, the requirements for the work of the refrigerant are different. For example, in the water heating mode, the effective work process of the refrigerant in the condenser is heat release, and in the dehumidification mode, the effective work process of the refrigerant in the evaporator is heat absorption. Through the above-mentioned configuration, the present invention can reasonably allocate the use of the refrigerant, so that the refrigerant can become effective work in both the heat release process and the heat absorption process, thereby improving the heat utilization rate of the entire water heater system.

[0057] Specifically, through the arrangement of the first reversing valve, the second reversing valve, and the ventilation pipeline, the present invention can be operated in four operation modes, namely, dehumidification mode, hot water making mode, first combined operation mode, and second combined operation mode. Here, the first combined operation mode is that the hot water making mode and the dehumidification mode are executed simultaneously, and the second combined operation mode is that the hot water making mode, the dehumidification mode, and the bathroom heater mode are operated simultaneously. The bathroom heater mode is also the working mode when the user takes a bath with hot water;

[0058] Among them, the first reversing valve and the second reversing valve are both bidirectional electronic expansion valves, which can not only adjust the flow rate of the refrigerant adaptively, but also control the flow direction of the refrigerant by its conduction state, so that the present invention can operate in different working modes;

[0059] The above four modes can be set according to the daily usage habits of the bathroom. Before bathing, the water heater needs to store hot water. At this time, it first enters the hot water making mode and starts to prepare hot water. During bathing, the second combined operation mode is turned on. At this time, the bathroom heater function is turned on, and the hot water making mode is used to replenish hot water for the hot water making tank, and dehumidification is performed through the dehumidification module. Then, after bathing is completed, the hot water is consumed, and the indoor humidity is very heavy. The first combined operation mode can be turned on. At this time, there is no need to turn on the bathroom heater function. It is only necessary to cooperate with the hot water making tank and the dehumidification module to perform the hot water making function and the dehumidification function at the same time. After completing the hot water making mode, the present invention can be converted to an independent dehumidification mode to further remove indoor moisture.

[0060] Each working mode of the present invention is described below respectively;

[0061] The high energy efficiency ratio water heater proposed by the present invention has a dehumidification mode;

[0062] In the dehumidification mode, the first reversing valve and the second reversing valve control the refrigerant to flow only between the first evaporator and the second evaporator.

[0063] Among them, the above dehumidification modes are specifically divided into: independent dehumidification mode, bathroom heater dehumidification mode, and independent bathroom heater mode;

[0064] In the independent dehumidification mode, the dehumidification module is connected to the outdoor ventilation pipeline, and the hot air generated by the second evaporator is blown to the outside;

[0065] In the Yuba dehumidification mode, 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 the independent bathroom heater mode, the dehumidification module is connected to both indoor and outdoor ventilation ducts, and the first evaporator is switched to draw air from the outside, and the hot air generated by the second evaporator is blown into the room.

[0067] See also Figure 2 , which is a schematic diagram of the refrigerant flow direction of the present invention in the dehumidification mode, at this time, the first reversing valve controls the upper pipeline of the first evaporator and the upper pipeline of the second evaporator to be connected, and both are disconnected from the condenser in the hot water tank, and the second reversing valve controls the lower pipeline of the first evaporator and the lower pipeline 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, and the refrigerant will only circulate between the first evaporator and the second evaporator, and the hot water tank will not participate in the circulation, that is, the hot water mode is not executed. At this time, the present invention works in the dehumidification mode, and the second evaporator acts as a condenser;

[0069] When the ventilation pipe connects the dehumidification module to the outside and the hot air generated by the second evaporator is blown to the outside, the present invention works in an independent dehumidification mode, which can be used after the hot water production is completed and when the bathing process is not in progress. At this time, there is no need for the condenser to provide heat for the room, and only the first evaporator is used to dehumidify the room through the refrigerant;

[0070] When the ventilation duct connects the dehumidification module to the room and blows the hot air generated by the second evaporator into the room, the present invention 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, thereby ensuring the indoor temperature. At the same time, the first evaporator starts to dehumidify the room.

[0071] When the ventilation duct connects the dehumidification module with both indoor and outdoor ventilation ducts, and controls the first evaporator to switch to draw air from the outside, and the hot air generated by the second evaporator is blown into the room, the present invention works in the independent bathroom heater mode. At this time, the second evaporator mainly plays a role, generating hot air through the second evaporator and blowing it into the room to preheat the bathroom.

[0072] It can be seen from the above settings that in the dehumidification mode of the present invention, the first evaporator and the second evaporator can also independently constitute a refrigeration or heating system. At the same time, in conjunction with the conduction direction of the ventilation pipeline, the present invention can be operated in independent dehumidification mode, bathroom heater dehumidification mode and independent bathroom heater mode, thereby making the present invention adaptable to various usage scenarios.

[0073] Furthermore, the high energy efficiency ratio integrated water heater proposed in the present invention also has a water-making mode;

[0074] In the hot water mode, the first reversing valve and the second reversing valve control the refrigerant to flow between the first evaporator and the hot water tank and between the second evaporator and the hot water tank;

[0075] The ventilation pipeline controls the first evaporator and the second evaporator to draw air from the outside at the same time.

[0076] See also Figure 3 , which is a schematic diagram of the refrigerant flow direction in the hot water making mode of the present invention. At this time, the first reversing valve and the second reversing valve connect the connecting pipeline between the first evaporator and the condenser, and the connecting pipeline between the second evaporator and the condenser. At this time, the refrigerant can circulate between the first evaporator and the condenser, and between the second evaporator and the condenser. At this time, the working principle of the hot water tank is consistent with the working principle of the hot water tank under the traditional structure. The first evaporator and the second evaporator inhale 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, so that the cold water is heated up and becomes hot water, and is stored in the hot water tank, realizing the hot water making function, so as to facilitate the use of hot water in the bathroom heater mode.

[0077] Furthermore, the high energy efficiency ratio integrated water heater proposed in the present invention 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 refrigerant to flow between the first evaporator and the hot water tank and between the second evaporator and the hot water tank;

[0079] The ventilation pipeline controls the first evaporator and the second evaporator to draw air from the room at the same time.

[0080] The first combined operation mode here is the dehumidification mode and the hot water mode mentioned above, which are executed simultaneously. Figure 4 , which is a schematic diagram of the refrigerant flow direction in the first combined operation mode of the present invention. In the first combined operation mode, the flow path of the refrigerant is the same as that in the hot water making mode. Only the ventilation pipeline needs to be adjusted, and the first evaporator and the second evaporator are changed to inhale air from the room. At this time, the working principle of the first evaporator and the second evaporator is consistent with the working principle of the dehumidification module under the traditional structure, and the working principle of the condenser in the hot water tank is consistent with the working principle of the condenser under the traditional structure. The main differences are:

[0081] In the traditional mode, the hot water tank and the dehumidification module are independently set up, and the two modes are respectively operated in different modules. There are actually both condensers and evaporators in the hot water tank, but the condenser plays a role in heat exchange to heat the cold water in the hot water tank, but the refrigerant in the evaporator can only exchange heat with the air for heat absorption. 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 plays a role in heat exchange and dehumidification. 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 setting of the present application, after the hot water tank and the dehumidification module are combined with each other, for the hot water tank, its useless evaporator part is transformed into the first evaporator and the second evaporator in the dehumidification module for dehumidification, and for the dehumidification module, its useless condenser part is transformed into the condenser in the hot water tank for hot water production. At this time, the heat release process and the heat absorption process of the refrigerant are both effective, that is, in this mode, the present invention can significantly improve the utilization rate of energy.

[0083] The first combined operation mode and the second combined operation mode are the two most important operation modes of the present invention. In these two operation modes, the heat absorption process and heat release process of the refrigerant can be fully utilized. However, the core idea of ​​the present invention is not just to propose the above two modes, but to propose a high energy efficiency integrated water heater, which can adapt to the operation of multiple operation modes, meet the applicability requirements of various scenarios, and improve the utilization rate of energy.

[0084] Furthermore, the high energy efficiency ratio integrated water heater proposed in the present invention has a second combined operation mode;

[0085] In the second combined operation mode, the first reversing valve and the second reversing valve control the refrigerant to flow 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 is the dehumidification mode, hot water mode and bathroom heater mode mentioned above, which are executed simultaneously. Figure 5, which is a schematic diagram of the refrigerant flow direction in the second combined operation mode of the present invention. In the second combined operation mode, the flow path of the refrigerant is similar to that in the first combined operation mode. The main difference lies in the refrigerant flow direction at the second evaporator. The first reversing valve and the second reversing valve are configured to control the refrigerant in the second evaporator to flow to the first evaporator, which is opposite to the flow direction of the refrigerant in the first combined operation mode. After this configuration, the second evaporator actually acts as a condenser, which can cooperate with the condenser in the water heating tank for heating. At this time, through the configuration of the ventilation pipeline, the first evaporator can draw air from the water vapor in the room (that is, the bathroom), thereby absorbing heat and exchanging 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 water heating tank for preparing hot water. The refrigerant entering the second evaporator exchanges heat with the indoor air, generates hot air and blows it into the room, thereby realizing the above-mentioned bathroom heater function.

[0088] It can be seen that the present invention realizes a combined system of a dehumidification module and a water heating tank through the above-mentioned arrangement, and cooperates with the ventilation duct to adjust the ambient temperature, which can solve the drawbacks existing in the application of a single household appliance, such as the dehumidifier causing the indoor ambient temperature to rise and the comfort level to decrease when in use, and the waste of cooling capacity of the outdoor unit when the water heater is in use.

[0089] The above four modes can be collectively referred to as three working conditions. The first working condition is independent dehumidification, which is the dehumidification mode mentioned above. At this time, the first evaporator and the second evaporator form a system, and the ventilation duct forms a cycle with the indoor environment to perform dehumidification.

[0090] The second working condition is independent hot water production, which is the hot water production mode mentioned above. At this time, the first evaporator and the second evaporator are both used as evaporator components, and the condenser is used as a condenser component to form a system, and air is drawn from the outside, which does not affect the indoor ambient temperature and humidity;

[0091] The third working condition is the combined working 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 part and form a system with the condenser, or the second evaporator and the condenser can form a condenser part and form a system with the first evaporator. On the basis of the second working condition, the indoor temperature and humidity are controlled by circulating indoors.

[0092] In the present invention, a corresponding operation panel can be provided 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 making function;

[0093] Automatically control the start and stop of heating according to the set water temperature in each time period;

[0094] By opening and closing the first reversing valve and the second reversing valve, and switching the ventilation pipeline, the hot water making function, the bathroom heater function and the dehumidification function 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, the present invention can automatically switch, and the dehumidification mode and the hot water making mode also support the timed shutdown function.

[0095] In addition, the present invention can also realize a clothes drying function, and it can set a folding clothes drying rack at the air outlet of the dehumidification module, so that clothes can be dried synchronously while dehumidifying the bathroom.

[0096] See also Figure 6 The present invention can also adopt a one-to-two external unit form, connecting the condenser in the hot water tank, the evaporator in the dehumidification module and the evaporator in the compressor in series, and by controlling the opening and closing of each reversing valve, one of them can be controlled separately not to participate in the system operation, thereby realizing the three operating modes of dehumidification mode, hot water mode, and combined mode (including the first combined operation mode and the second combined operation mode).

[0097] Furthermore, in the present invention, when the above modules are arranged, since the humidity in the bathroom is at a high temperature and the gas rises upward, the dehumidification module part can be installed in the bathroom in a suspended ceiling style, which can more thoroughly remove the humidity in the room and avoid moisture residue, while also saving space; at the same time, the fins of the first evaporator and the second evaporator in the dehumidification module are arranged obliquely, and the guide groove is used to guide the water to the external unit for discharge, so as to avoid the condensed water from dripping back into the room;

[0098] In order to adapt to the high humidity environment in the bathroom all year round, the above-mentioned fins need to use golden anti-corrosion fins to extend their service life, and at the same time add a layer of grille to cover it and ensure its appearance.

[0099] The present invention can also design air outlets 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, it can help accelerate dehumidification, and on the other hand, it can provide a bathroom heater function to increase the room temperature of the bathroom. At the same time, the air outlet needs to be set to avoid blowing directly on people.

[0100] Furthermore, the present invention also proposes a water heater system, which has the above-mentioned high energy efficiency ratio water heater integrated machine.

[0101] Compared with the prior art, the present invention has the following beneficial effects:

[0102] The present invention rationally utilizes the two complementary processes of dehumidification and hot water making, integrates the hot water tank and the dehumidification module, and allows the refrigerant to become effective work in both the heat release process and the heat absorption process. The present invention can simultaneously meet the needs of hot water making and dehumidification, thereby improving the heat utilization rate of the entire water heater system.

[0103] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
