Fig. 1 shows a perspective view of a heating stove 10 in an embodiment of the present application, and fig. 2 shows a schematic view of the heating stove in an embodiment of the present application.
Referring to fig. 1 and 2, a heating stove 10 according to an embodiment of the present application includes a heating stove body 110 and a water tank assembly.
Referring to fig. 1 again in combination with fig. 3, the water tank assembly is disposed at one side of the heating stove body 110 side by side along a first direction, and includes two water tanks 130 having a heating function disposed side by side along a second direction and communicated with each other. Wherein the heating stove body 110 has a front side, and a first side and a second side adjacent to the front side and parallel to each other, the first direction is a direction in which the first side is directed to the second side, and the second direction is perpendicular to the front side of the heating stove body 110. Particularly, in the embodiment shown in fig. 1 and 3, the first direction is a left-right direction, and the second direction is a front-rear direction, so that the water tank assembly and the heating stove body 110 can be compactly arranged.
The orthographic projections of the two water tanks 130 in the water tank assembly on the second side face completely fall into the second side face, and it can be understood that the dimension of the water tank assembly along the second direction is not more than the dimension of the heating stove body 110 along the second direction, then the occupied dimension of the heating stove body 110 and the water tank assembly along the first direction is substantially equal to the sum of the dimensions of the heating stove body 110 and one water tank 130 along the first direction, and the occupied dimension of the heating stove body 110 and the water tank assembly along the second direction is equal to the dimension of the heating stove body 110 along the second direction. The water tank 130 with larger capacity is generally selected under the condition of the same surface area, correspondingly, the water tank 130 is selected as the water tank 130 with a cylindrical structure, so that a single large water tank with a cylindrical structure is taken as a reference object, the comparison reference is carried out under the condition that the volume of the reference object is equal to the total volume of the two water tanks 130, and the height of the reference object is equal to the height of the water tank 130, and the occupied size of the heating stove body 110 and the single large water tank along the first direction is approximately equal to the sum of the sizes of the heating stove body 110 and the single large water tank along the first direction; the occupied size of the heating stove body 110 and the single large tank in the second direction is still equal to the size of the heating stove body 110 in the second direction. Obviously, the diameter of the water tank 130 is smaller than that of the single large water tank, and thus, the occupied size of the heating stove body 110 and the single large water tank in the first direction is larger than that of the heating stove body 110 and the water tank assembly in the first direction. Therefore, compared with the whole occupied space of a single large water tank and the heating stove body 110, the whole occupied space of the two water tanks 130 and the heating stove body 110 is smaller, the size of the whole machine is favorably reduced, and the installation space of the heating stove 10 can be reduced to the maximum extent.
In some embodiments, the water tanks 130 are cylindrical structures, the diameter of the water tanks 130 is 140mm, and the total water volume of the two water tanks 130 is 18.5L; if a single large water tank with the volume of 18.5L is used as a reference object; in the case where the large tanks and the water tank 130 are the same height, the diameter of the single large tank is about 210 mm. If the heating stove body 110 has a dimension L along the first direction1And a dimension in the second direction of L2Wherein L is2Greater than 280mm, then the overall footprint of the two tanks 130 and the heating stove body 110 in the first direction is substantially equal to L1+140mm, the overall footprint of the two tanks 130 and the heating stove body 110 in the second direction being equal to L2(ii) a And a single large tank and heating stove body 110 integrated in a first directionFootprint size substantially equal to L1+210mm, the overall footprint of the single large tank and heating stove body 110 in the second direction is also equal to L2;It is apparent that the overall space occupied by the two water tanks 130 and the heating stove body 110 is smaller.
Further, the first side surface and the second side surface are perpendicular to the front side surface.
Referring to fig. 2 again, one water tank 130 on the upstream side is connected to the second end of the bathroom heat exchanger 120 through a pipeline, and the other water tank 130 on the downstream side provides bathroom hot water through a bathroom water supply pipeline, specifically, the water inlet pipe 150 is connected to the bathroom heat exchanger 120 and the water inlet pipe 150 is communicated with the second end of the bathroom heat exchanger 120, so that the fluid in the water inlet pipe 150 flows to the bathroom heat exchanger 120 and the two water tanks 130 in sequence and finally flows out through the bathroom water supply pipeline. And the heating stove body 110 has a heating outlet pipe 111, and hot water made through the heating stove body 110 can flow out through the heating outlet pipe 111 for user heating. Wherein the heating water outlet pipe 111 is configured to selectively communicate with the first end of the sanitary heat exchanger 120, then the hot water flowing out of the heating water outlet pipe 111 selectively exchanges heat with the cold water flowing from the water inlet pipe 150 to the water tank 130 to provide sanitary hot water through the sanitary water supply line.
The water in the water tank 130 can be heated during peak shifting power utilization or peak shifting water utilization, and the water in the bathroom water outlet pipe 140 can be heated, and then the bathroom water can be used instantly after being opened when a user uses the bathroom water.
Optionally, the sanitary water supply line is a sanitary water outlet pipe 140. The water flowing from the inlet pipe 150 to the outlet pipe 140 of the bathroom can exchange heat with the hot water in the two water tanks 130 in sequence, and the use of the two water tanks 130 can still ensure the heat exchange effect compared with the single large water tank.
Further, a heating bathroom switching valve 1111 is disposed at an outlet end of the heating outlet pipe 111, and a heating branch pipe 113 and a bathroom branch pipe 114 connected to a first end of the bathroom heat exchanger 120 are disposed at two outlets of the heating bathroom switching valve 1111, respectively. The hot water flowing out of the heating water outlet pipe 111 may be respectively flowed into the heating branch pipe 113 and/or the sanitary branch pipe 114 by means of the heating sanitary switching valve 1111.
Optionally, the heating stove body 110 includes a heating water return pipe 112 connected to the bathroom heat exchanger 120, one end of the heating water return pipe 112 far away from the bathroom heat exchanger 120 is connected to the heating water outlet pipe 111, wherein the heating water return pipe 112 and the bathroom branch pipes 114 are communicated with each other, the water inlet pipe 150 is connected to the heating water return pipe 112, cold water in the water inlet pipe 150 can flow to the heating water return pipe 112, and after being heated by the heating stove body 110, hot water obtained after heating can flow out from the heating water outlet pipe 111. In addition, the hot water flowing out of the heating water outlet pipe 111 selectively contacts with the fluid flowing from the water inlet pipe 150 to the bathroom heat exchanger 120 for heat exchange, and after the heat exchange is completed, the hot water flowing out of the heating water outlet pipe 111 may flow to the heating water outlet pipe 111 again through the heating water return pipe 112, and may be heated again by the heating stove body 110 in the process that the hot water flows to the heating water outlet pipe 111 again.
Specifically, the heating stove body 110 further includes a combustion mechanism 116 and a heating heat exchanger 115, high-temperature flue gas generated by combustion of the combustion mechanism 116 passes through the heating heat exchanger 115 and exchanges heat with water flowing from the heating water return pipe 112 to the heating water outlet pipe 111, so that the water is heated, and the obtained hot water flows out from the heating water outlet pipe 111.
It will be appreciated that the fluid in the sanitary branch line 114 exchanges heat with the fluid flowing from the inlet pipe 150 to the sanitary outlet pipe 140 by means of the sanitary heat exchanger 120, so that the fluid flowing out of the heating outlet pipe 111 is selectively in heat exchange contact with the fluid flowing from the inlet pipe 150 to the sanitary heat exchanger 120. That is, when the heating and bathroom switching valve 1111 is switched to communicate the heating outlet pipe 111 and the bathroom branch pipes 114, the cold water flowing from the inlet pipe 150 to the bathroom outlet pipe 140 flows through the bathroom heat exchanger 120, and exchanges heat with the hot water flowing from the bathroom branch pipes 114 to the bathroom heat exchanger 120, so that the cold water flowing from the inlet pipe 150 to the bathroom outlet pipe 140 is heated, and the heated hot water flows out from the bathroom outlet pipe 140 for the bathroom of the user. When the heating bath switching valve 1111 is switched to connect the heating water outlet pipe 111 with the heating branch pipe 113, the hot water flowing out of the heating water outlet pipe 111 flows into the heating branch pipe 113 for heating users. At this time, the hot water flowing out of the heating water outlet pipe 111 does not pass through the sanitary branch line 114 and does not exchange heat with the cold water flowing from the water inlet pipe 150 to the sanitary water outlet pipe 140.
Alternatively, a heating circulation pump 1121 is disposed on the heating water return pipe 112, the heating water outlet pipe 111, and the bathroom branch pipes 114 are connected to form a heating circulation pipe, and water in the heating circulation pipe circulates and flows under the driving of the heating circulation pump 1121.
Further, the heating stove 10 further includes a bathroom return pipe 1401 connected to the bathroom outlet pipe 140, and one end of the bathroom return pipe 1401 far away from the bathroom outlet pipe 140 is connected to the inlet pipe 150, so that the inlet pipe 150, the bathroom heat exchanger 120, the bathroom outlet pipe 140 and the bathroom return pipe 1401 are connected to form a bathroom circulation pipeline. The hot water flowing out from the bathroom outlet pipe 140 can flow into the inlet pipe 150 through the bathroom return pipe 1401, and flow to the bathroom heat exchanger 120 and the bathroom outlet pipe 140 again, which is beneficial to the heat exchange: the water in the bathroom circulating pipeline can exchange heat with the water in the water tank 130 quickly, and the water in the bathroom circulating pipeline can also exchange heat with the hot water in the bathroom branch pipeline 114 quickly, so that the heat exchange efficiency can be improved.
Can set up bathroom circulating pump 1402 on bathroom return water pipe 1401, make the water circulation in the bathroom circulating line flow with the help of bathroom circulating pump 1402, be favorable to the circulation of heat transfer to go on, improve heat exchange efficiency.
Further, referring to fig. 2 again in combination with fig. 4, each of the water tanks 130 includes a tank body 131 and a tank heat exchange pipe 132 disposed in the tank body 131, and the water tank 130 is in heat exchange contact with the fluid flowing from the inlet pipe 150 to the outlet pipe 140 of the bathroom by means of the tank heat exchange pipe 132. The water tank heat exchange tubes 132 of the two water tanks 130 are connected to each other, and ends of the water tank heat exchange tubes 132 of the two water tanks 130, which are far away from each other, are respectively connected to the second end of the sanitary heat exchanger 120 and the sanitary water supply pipeline, that is, ends of the water tank heat exchange tubes 132 of the two water tanks 130, which are far away from each other, are respectively connected to the second end of the sanitary heat exchanger 120 and the sanitary water outlet pipe 140. In the process of flowing from the water inlet pipe 150 to the bathroom water outlet pipe 140, the cold water flows into the two water tank heat exchange pipes 132 in sequence, can exchange heat with the water in the two water tanks 130 in sequence, and finally flows to the bathroom water outlet pipe 140. The water flowing from the water inlet pipe 150 to the bathroom water outlet pipe 140 can be heated by means of the water tank 130 with the heating function, and the water in the water tank 130 and the water in the bathroom water outlet pipe 140 can also be heated during peak-shifting power utilization, so that the effect of heating immediately after opening is achieved, and the user experience can be improved.
This heating stove 10 is during the use, the hot water that heating outlet pipe 111 flows out can flow to bathroom lateral conduit 114, make the hot water that flows in bathroom lateral conduit 114 and the cold water that flows to bathroom outlet pipe 140 by inlet tube 150 carry out the heat exchange, the hot water that obtains after the heat exchange can pass through the water tank heat exchange tube 132 of water tank 130, still can carry out the heat exchange with the water of storing in water tank 130, and prevent the water in the water tank and scatter and disappear from the heat of the hot water of bathroom outlet pipe 140 from bathroom heat exchanger 120 with the help of the water tank of taking the heating function, can realize the heat preservation of water tank 130 and bathroom outlet pipe 140, make the user when using the bathroom water, can reach and open the effect of heating promptly, user's experience sense has been improved.
Further, referring again to fig. 4, the tank heat exchanging pipe 132 is constructed to spirally extend from one end of the tank body 131 to the other end of the tank body 131 around the center line of the tank body 131. The contact area between the water tank heat exchange tube 132 and the water in the water tank body 131 can be increased, the heat exchange efficiency between the water in the water tank heat exchange tube 132 and the water in the water tank body 131 can be increased, and the water flowing from the water inlet tube 150 to the bathroom water outlet tube 140 can be heated more quickly.
Further, referring to fig. 2 again, each of the tank bodies 131 is provided with a heating member 133 for heating the liquid in the corresponding tank body 131, so that two heating members 133 can be heated together, or one of the heating members 133 can be heated, and the number of the heating members 133 to be heated is selected according to actual needs.
Further, referring to fig. 2 again, one end of the heating element 133 is connected to the water tank body 131, and the other end extends into the water tank body 131, and the heating element 133 is embedded in the water tank 130, so that the overall occupied space of the water tank 130 can be further reduced.
Alternatively, the heating member 133 is a heating coil, which can increase the contact area of the heating member 133 with the fluid in the water tank 130, thereby improving the heating efficiency and the heat-insulating effect of the water tank 130.
Alternatively, the heating member 133 is an electric heating member that heats the water in the water tank 130 by electric heating.
It should be noted that, the peak power consumption can be staggered, so that the water in the water tank 130 is heated to a heat preservation state, so as to ensure that the user can be heated when using the bathroom water, and the experience of the bathroom water is improved.
Further, referring to fig. 1 again, the heating stove 10 further includes a housing 160 (a partial structure of the housing 160 is schematically shown in fig. 1), the heating stove body 110 and the water tank assembly are both located in the housing 160, and the heating stove body 110 and the water tank assembly are installed in the housing 160, so that the overall carrying and the overall installation of the heating stove 10 are facilitated, and the heating stove is more beautiful.
Fig. 5 is a flow chart showing a control method of the heating stove 10 in an embodiment of the present application.
Referring to fig. 5, the control method of the heating stove 10 includes the steps of:
causing the heating stove 10 to start.
S410, under the condition that the heating stove 10 is in the heating bathroom mode, whether the actual water temperature of the bathroom water outlet pipe 140 is larger than or equal to a first preset temperature T or not is judged1。
When the heating stove 10 is in the heating bathroom mode, the heating water outlet pipe 111 is communicated with the bathroom branch pipes 114. The fluid flowing out of the water inlet pipe 150 flows to the bathroom heat exchanger 120 and the bathroom water outlet pipe 140 in sequence, and the fluid flowing out of the heating water outlet pipe 111 flows to the bathroom branch pipes 114. The cold water flowing from the water inlet pipe 150 to the bathroom heat exchanger 120 and the bathroom water outlet pipe 140 is heated by the hot water flowing from the heating water outlet pipe 111, that is, the cold water flowing from the water inlet pipe 150 to the bathroom water outlet pipe 140 can be heated by the hot water prepared by the heating furnace body 110 when the heating furnace 10 is in the heating bathroom mode.
S420, if the actual water temperature of the bathroom water outlet pipe 140 is greater than or equal to the first preset temperature T1And stopping the heating bathroom mode. First presetTemperature T1Equivalent to the target outlet water temperature T of the outlet pipe 140 of the bathroom0。
S422, the heating stove 10 is controlled to be switched from the heating bathroom mode to the water tank heat preservation mode, so that the actual water temperature of the bathroom water outlet pipe 140 is not less than a second preset temperature T2Wherein the second preset temperature T2Greater than or equal to a first preset temperature T1. By using the heating bathroom mode, the actual water temperature of the bathroom water outlet pipe 140 can be heated to the target water outlet temperature T of the bathroom water outlet pipe 1400Stopping the heating bathroom mode, and maintaining the actual water temperature of the bathroom water outlet pipe 140 at a first preset temperature T or higher by means of the water tank heat preservation mode1Second predetermined temperature T2That is, the water in the bathroom outlet pipe 140 is preheated in the heating bathroom mode, and the water in the bathroom outlet pipe 140 is insulated in the water tank insulation mode, so that the operation time of the heating bathroom mode can be reduced, the frequent switching between the heating bathroom mode and the single heating mode due to the insulation of the bathroom outlet pipe 140 during the heating of the heating stove 10 can be avoided, and the influence on the heating of the user can be reduced.
It should be noted that, when the heating stove 10 is in the water tank heat preservation mode, the heating outlet pipe 111 is linked together with the heating branch pipeline 113, and the heating outlet pipe 111 is not linked together with the bathroom branch pipeline 114, so, the fluid that the heating outlet pipe 111 flows out only flows to the heating branch pipeline 113, and the heating stove 10 is still in the single heating mode, can satisfy heating demand and bathroom demand simultaneously under the condition of not influencing each other, reduces the influence to user's heating better. Specifically, when the heating stove 10 is in the water tank heat preservation mode, the fluid flowing out of the water inlet pipe 150 flows to the bathroom heat exchanger 120 and the bathroom water outlet pipe 140 in sequence, and the fluid flowing out of the heating water outlet pipe 111 flows to the heating branch pipe 113. The actual water temperature of the bathroom water outlet pipe 140 is not less than the second preset temperature T by using the water tank heat preservation mode2The actual water temperatures of the bathroom outlet pipe 140 and the bathroom return pipe 1401 and the water temperature of the water in the water tank 130 are approximately consistent and are in a heat-preserving state.
Optionally, the first preset temperature T1Equal to the target outlet water temperature T of the bathroom outlet pipe 1400The second predetermined temperature T may be set in consideration of heat loss in the pipe2Is greater than the target outlet water temperature T of the bathroom outlet pipe 1400。
In particular, a first preset temperature T1Is equal to T0Second predetermined temperature T2Is equal to T0+3。
Further, the heating stove 10 further comprises a control device, and the control device is used for judging whether the actual water temperature of the bathroom water outlet pipe 140 is greater than or equal to the first preset temperature T or not when the heating stove 10 is in the bathroom water mode and in the heating bathroom mode1(ii) a If yes, the heating stove 10 is controlled to be switched from the heating bathroom mode to the water tank heat preservation mode, so that the actual water temperature of the bathroom water outlet pipe 140 is not less than the second preset temperature T2。
In some embodiments, the bathroom water outlet pipe 140 is provided with a temperature probe, and the temperature probe and the heating bathroom switch valve 1111 are electrically connected to the control device respectively. The actual water temperature of the bathroom water outlet pipe 140 can be obtained by means of the temperature probe, and the control device is used for controlling the heating bathroom switching valve 1111 to switch to the heating water outlet pipe 111 to be communicated with the bathroom branch pipeline 114 according to the actual water temperature obtained by the temperature probe, so that the heating stove 10 operates in the heating bathroom mode. The control device is further configured to control the heating bathroom switching valve 1111 to switch to the heating water outlet pipe 111 to communicate with the heating branch pipe 113 according to the actual water temperature obtained by the temperature probe, so that the heating stove 10 operates the water tank heat preservation mode and the single heating mode.

After heating stove 10 starts, can make heating stove 10 running water tank heat preservation mode before the user uses the bathroom water, and then make bathroom outlet pipe 140's actual temperature not less than the second and predetermine temperature T2. The water in the water tank 130 can be heated under the condition of off-peak power utilization, and the water temperature in the water tank 130 is approximately consistent with the water temperature of the bathroom water outlet pipe 140 and tends to be in a constant temperature state, so that the effect of instant heating and instant heating can be achieved when a user uses bathroom water in a power utilization peak period. In addition, before the user uses the bathroom water, the actual water temperature of the bathroom water outlet pipe 140 is greater than or equal to the second preset temperature T2And a second predetermined temperature T2Greater than or equal to a first preset temperature T1The time for preheating by using the heating bathroom mode can be further reduced, and the influence on the heating of users can be further reduced.
Optionally, in the process of preheating in the heating bathroom mode, water in the bathroom circulation pipeline may be circulated by the bathroom circulation pump 1402, so as to improve the preheating efficiency. The water in the bathroom circulating pipeline can circularly flow under the heat preservation mode of the water tank, so that the heat preservation efficiency is improved, the water in the bathroom circulating pipeline is circulated under the driving of the bathroom circulating pump 1402, and finally the bathroom circulating pipeline is circulatedThe water temperature in the water tank 130 is consistent with the water temperature in the water tank, which is more beneficial to quickly make the actual water temperature of the bathroom water outlet pipe 140 greater than or equal to the second preset temperature T2。
Optionally, the heating stove 10 is operated in the tank warming mode in case of off-peak electricity utilization to heat the water in the tank 130 such that the water temperature in the tank 130 and the water temperature of the bathroom outlet pipe 140 are substantially at the second preset temperature T2And the water tends to be in a constant temperature state, so that the water can achieve the effect of heating when the user uses the water for the bathroom at the peak time of power utilization.

Wherein the lower limit temperature of the heat preservation is less than the third preset temperature T3. According to the critical time t of water for bathroom1And judging whether the user uses the bathroom water for a short time. The heat-retaining lower limit temperature is a lower limit temperature of the heat-retaining mode of the operation tank of the heating stove 10, and thus, whether the heat-retaining mode of the operation tank of the heating stove 10 is required to be switched to another mode or not is judged under the condition that the heating stove is not in the bathroom water use mode for the first time. At this time, the operation time of the bathroom water mode is greater than the bathroom water critical time t1And the actual water temperature of the bathroom outlet pipe 140 is less than or equal to the lower temperature limit of the heat preservation, it indicates that the user starts to use the bathroom water for a long time, the user has a possibility of bathing, and the actual water temperature of the bathroom outlet pipe 140 is lower than the third preset temperature, which also indicates that the water tank heat preservation mode can no longer meet the bathroom requirements of the user at this time, so the heating mode by the heating element 133 is not suitable, and the heating bathroom mode is more suitable for use, for example, the heating mode is performed by means of the combustion mechanism 116 of the heating stove body 110, the heating heat exchanger 115, the bathroom heat exchanger 120, and the like.

And by means of the two conditions, the heating stove 10 can select the water tank heat preservation mode preferentially, the running time of the heating bathroom mode is reduced, and the influence on the heating of users is also reduced.
Further, the actual water temperature of the bathroom water outlet pipe 140 is not less than the second preset temperature T2The method is realized by adopting the following steps:
so that the liquid in one 130 of the two water tanks 130 is heated, and after a preset time interval, the actual water temperature of the bathroom water outlet pipe 140 is less than the second preset temperature T2Heating the liquid in the other 130 of the two water tanks until the actual water temperature of the bathroom outlet pipe 140 is not less than the second preset temperature T2. The water in the corresponding water tank 130 can be heated by the heating element 133, the two water tanks 130 of the water tank assembly are respectively and independently controlled, the heating element 133 corresponding to one water tank 130 is firstly started, and after a preset time interval, the water outlet pipe 140 of the bathroom is real according to the fact of the bathroomWhether the water temperature is lower than the second preset temperature T2It is judged whether or not the heating member 133 corresponding to the other water tank 130 is activated. During this period, if the actual water temperature of the bathroom outlet pipe 140 is greater than or equal to the second preset temperature T2Then, the heating member 133 is stopped from heating.
In some embodiments, the predetermined time interval is 3-10 minutes.
Alternatively, all the heating members 133 are electrically connected to the control device, respectively. The control device heats at least one of the two heating elements 133 according to the actual water temperature of the bathroom water outlet pipe 140 obtained by the temperature probe.
Optionally, the water in the bathroom circulating pipeline is circulated under the driving of the bathroom circulating pump 1402, and finally the water temperature in the bathroom circulating pipeline is kept consistent with the water temperature in the water tank 130, which is more beneficial to quickly making the actual water temperature of the bathroom water outlet pipe 140 greater than or equal to the second preset temperature T2。
In some embodiments, the predetermined time interval is 3-10 minutes.
In some embodiments, each water tank 130 is provided with a water tank heat exchange pipe 132 and a heating element 133 inside, so that the water tank 130 has the characteristics of small occupied space, large water storage capacity, constant water temperature and the like, the overall size of the heating stove 10 is small, and the installation space of the heating stove 10 can be reduced to the maximum extent.
